DETAILED DESCRIPTION OF THE EMBODIMENTS

[0190] The invention will be described with reference to the Figures.

[0191] It should be understood that the detailed description and specific examples, while indicating exemplary embodiments of the apparatus, systems and methods, are intended for purposes of illustration only and are not intended to limit the scope of the invention. These and other features, aspects, and advantages of the apparatus, systems and methods of the present invention will become better understood from the following description, appended claims, and accompanying drawings. It should be understood that the Figures are merely schematic and are not drawn to scale. It should also be understood that the same reference numerals are used throughout the Figures to indicate the same or similar parts.

[0192] One aspect of the invention provides a partitioning component for dividing a feeding bottle into two sections: one associated with a container part of the bottle and one associated with a teat part of the bottle. The partition allows for at least partial retention of liquid in the teat part even when the bottle is tipped in a horizontal position, the more natural position for feeding a user such as a baby or toddler. To enable flow of fluid between the two sections, the partitioning component comprises a passageway arrangement which comprises one or more openings and the passageway arrangement configured to enable flow of both liquid and air across the partition in different directions. This allows liquid to pass in, and air to pass out, of the teat section during filling of the teat. To enable maximal retention of liquid inside the teat section when the bottle is tilted in the horizontal position, the openings of the passageway arrangement are all confined to a single region of the partitioning component which, in use, is arranged offset on one diametric side of the bottle volume or of the teat volume.

[0193] FIG. 1 illustrates a feeding bottle device 100 in an unassembled (FIG. 1a) and assembled (FIG. 1b) state in cross-sectional view. Feeding bottle device 100 comprises a teat component 110, which is attached to a container component 120 by means of an attachment component 130. The attachment component may for example be in the form of a locking ring. It may comprise a screw thread. Other possibilities are also possible such as a friction fit coupling for instance.

[0194] The teat component 110 defines a teat volume 115 therein. The container component 120 defines a container volume 125 therein. When the bottle 100 is assembled, the teat volume and container volume together form a total enclosed volume of the bottle. The bottle has a longitudinal axis 145 parallel with the length of the container, the axis illustrated by dotted line 145. The bottle has a base at one longitudinal end, the base defined by an end wall of the container component, and a top end at the other longitudinal end, formed by the teat component.

[0195] Usually, feeding bottle device 100 and more precisely a container volume 125 within container component 120 is filled with a liquid food, such as milk, which is then fed to an infant out of teat component 110. For this purpose, feeding bottle device 100 in the assembled state illustrated in FIG. 1 is maintained at an angle which allows milk or other liquid to enter the teat volume 115 within teat component 110. The position in FIG. 1 corresponds to an operating position, in which feeding bottle device 100 is inclined such that a teat component 110 points downwards at a certain angle such that liquid enters a teat volume 115.

[0196] The inclination shown in FIG. 1 is unfavorable since it differs from a natural feeding position of an infant, which is substantially horizontal, and since it favors the infant's swallowing of air. Nevertheless, despite being unfavorable, feeding with the illustrated inclination is classically performed in order to keep teat volume 115 filled with liquid and not with air through gravity even if a liquid level within container component 120 drops.

[0197] To allow a more horizontal feeding, embodiments in accordance with the present invention provide a partitioning component 210 arranged to fluidly divide the bottle volume into two longitudinal sections, a teat section extending from the top end of the bottle to the partitioning component, and a container section extending from the partitioning component toward the base of the bottle.

[0198] FIG. 2 illustrates a first example embodiment in accordance with one aspect of the present invention.

[0199] The partitioning component 210 is shown in FIG. 2.

[0200] The partitioning component 210 comprises a fluid passageway arrangement 215 comprising one or more openings 225 for permitting flow of fluid across the partitioning component.

[0201] The passageway arrangement 215 is located offset from a center of the component (indicated by a cross illustrated at the center of the component in FIG. 2b), on one diametric side of the partitioning component, and wherein the remainder of the partitioning component is fluid impermeable. A diametric dimension, D, of the partitioning component 210 is indicated in FIG. 2b.

[0202] The passageway arrangement 215 is configured to permit flow of both liquid and air in different directions across the partitioning component.

[0203] The partitioning component in this example is illustrated as located at the interface between the container component 120 and the teat component 110. As such, the teat section and container section correspond in this case respectively to the teat volume 115 and container volume 125 referred to previously, and thus these integers may be referred to interchangeably in the descriptions to follow.

[0204] However, the partitioning component can be positioned at any point along the longitudinal length of the bottle, for example it may be further inside the length of the container toward the base end, or may be further inside the teat component. In these cases, the teat section and container section may not correspond exactly to the teat volume 115 and the container volume 125.

[0205] The partitioning component 210 for example comprises a membrane or disk extending radially across the bottle volume between the inner walls of bottle.

[0206] The partitioning component 210 has a diametric or radial dimension, D, associated with it. It may have a uniform diameter or radius (e.g. in the case of a circular component), or the radius or diameter may vary in length as a function of angle about a center point of the component (e.g. oval or elliptical component). The outer boundary of the component may be generally round, e.g. an outer envelope is generally round, but shaped to match a shape of the outline of the inner walls of the bottle between which it extends. For example it may have a polygonal outer boundary shape in some examples.

[0207] The partitioning component 210 is configured to be arranged in the bottle with the diametric dimension extending obliquely to the bottle longitudinal axis, for example extending perpendicularly to the longitudinal axis 145.

[0208] The passageway arrangement 215 in this example is shown comprising a single opening 225, located adjacent one edge of the partitioning component, and configured to permit flow of both liquid and air in different directions across the partitioning component. As shown, there are no other openings in the passageway arrangement, so that at least one whole diametric side of the partitioning component is fluid impermeable. In this example, the passageway arrangement 215 is at a distance from an outer boundary of the partitioning component no greater than one quarter of the diametric height, D, of the partitioning component 210.

[0209] However, as will be seen from the embodiments discussed below, this is represents one example only, and the configuration of the passageway arrangement 215 may differ in different embodiments.

[0210] Functioning of feeding bottle device 100 is as described as follows. A caregiver assembles feeding bottle device 100 by usually inserting teat component 110 into attachment component 130, optionally then covering this assembly using a cap (not shown). Container component 120 is filled with milk or other liquid food and then partitioning component 210 is provided in the opening of container volume 125 before attachment component 130 is attached to container component 120, for instance by screwing it on.

[0211] After assembly, the filling of the teat section 115 is schematically and exemplarily illustrated in FIG. 2a. The feeding bottle 100 is turned upside down, i.e. teat component 110 is facing vertically down, to allow the teat section 115 to be filled with milk or other liquid 150 provided in container component 120. The passageway arrangement 210 permits flow of liquid 150 into the teat section 115, and simultaneous flow of air 160 outward from the teat section into the container section 125. Air 160, which previously was present in teat volume 115, can thus escape teat volume 115 through the passageway arrangement 215, and liquid 150 present in container volume 125 can at the same time pass into teat volume 115.

[0212] Once teat volume 115 is filled, feeding of the infant (or baby, or other user) can start.

[0213] FIG. 2c schematically and exemplarily illustrates a feeding position in which feeding bottle device 100 is positioned substantially horizontally. Teat volume 115 is completely filled with liquid and liquid drawn from teat component 110 by the infant is replaced through the passageway arrangement 215 with liquid 150 from the container volume 125.

[0214] Due to the fact that the passageway arrangement 215 is offset from the center on one diametric side, this means that a majority area portion of the partitioning component, extending diametrically above the passageway arrangement 215 is fluid impermeable, and thus does not allow leakage of fluid out from the teat section. This means that the volume of liquid 150 received in the teat section 115 after filling is effectively retained inside the teat by the fluid-impermeable major region of the partitioning component 210. As such, a filled teat can be maintained, making it easier for a user to draw fluid even in the horizontal position, and avoiding the possibility of air becoming trapped at an upper region of the teat section.

[0215] The only fluid communication between the teat section 115 and the container section 125 is via the passageway arrangement 215. Since this is positioned in an eccentric, offset position, it means that this arrangement is generally always located beneath a level of the liquid 150 in the container section. As such, ingress of air into the teat section in the horizontal position, from the container section, is avoided, since only the liquid is in communication with the passageway arrangement. However, more liquid can be continuously drawn in to the teat section as the infant or other user feeds, to thereby keep the teat section 115 filled with liquid.

[0216] Thus it can be seen the configuration of the passageway arrangement 215 enables inflow of liquid and outflow of air during filling of the teat, and furthermore enables effective retention of received liquid filling the teat section 115 when in the horizontal position.

[0217] The bottle may comprise a further fluid passage arranged to provide fluid communication between an outside of the bottle and the container section of the bottle volume. This allows air to enter the container section as liquid is drawn from the bottle through the teat.

[0218] The further fluid passage may for example comprise an inlet (e.g. valve) in the teat component fluidly connected to an outside of the bottle, and further fluidly connected (e.g. via a connection pipe or conduit) to the container section (for example by-passing the teat section). In one set of embodiments for instance, the inlet may be fluidly connected to the container section via a passageway that runs at least in part through the body of the partitioning component. For example the partitioning component may comprise a fluid inlet arranged to fluidly couple with the fluid inlet or valve in the bounding wall of the teat section when the bottle is assembled, and to channel air from this inlet through a conduit running through at least a part of the partitioning component body, and then out through an outlet fluidly coupled with the container section of the volume when the bottle is assembled. This outlet is preferably arranged on a diametrically opposite side of the partitioning component to the passageway arrangement 215. For example, the fluid conduit may extend in a circumferential path around at least a portion of the partitioning component to deliver air to the outlet into the container section. It may therefore provide a fluid guidance ring. The fluid conduit does not provide fluid communication between the container volume 125 and the teat volume 115, but by-passes this teat volume.

[0219] The fluid outlet to the container component may comprise an extended channel section which extends a certain distance longitudinally into the container component so that the air is delivered at a region of the container component further towards a base of the container. This may avoid the air entering any liquid collected at a top of the container volume, for example when the bottle is tilted toward the teat during drinking.

[0220] Alternatively an air inlet (e.g. valve) may be provided in the container component providing fluid connection between the outside of the bottle and the container section 125 of the volume to permit entry of air as fluid leaves the container component.

[0221] As noted, the passageway arrangement 215 is configured to permit simultaneous flow of liquid and air in opposite directions across the partitioning component.

[0222] In particular, the one or more openings of the passageway arrangement are sized and shaped to provide two simultaneous fluid flow-paths, separated spatially, to permit said flow of both liquid and air.

[0223] In the example of FIG. 2, the passageway arrangement 215 consists of a single opening 225 (preferably a through-hole in the partitioning component 210) which is of sufficient size to provide two flow paths in opposite directions through the opening at the same time.

[0224] By way of non-limiting, example, it has been found in one set of experiments by the inventors that a single opening of diameter greater than 10 mm is sufficient for two flow paths to be reliably provided across the opening. More preferably, the single opening may be provided with diameter greater than 12 mm, for example greater than 14 mm. These represent one example range of dimensions which may be advantageous in accordance with one or more embodiments. However, opening sizes smaller than those set out above may also be functional, and the optimal size for the opening may depend upon the size of the bottle volume (and hence the likely liquid pressure through the holes) and also the materials of the partitioning component. Thus the above example dimensions are not limiting for the inventive concept.

[0225] FIG. 3 illustrates a variation on the embodiment of FIG. 2. This embodiment is the same as that of FIG. 2 in all respects except that the single opening 225 of the passageway arrangement 215 is elongate, i.e. is longer in one dimension (‘elongate dimension’) than it is wide.

[0226] Making the opening elongated will result in a greater flow area and thus an improved fluid flow, without any need to the need to bring the hole closer to the center of the partitioning component

[0227] Moreover, the elongate hole better enables the spatial separation of the liquid and air flowpaths. As mentioned above, preferably the passageway arrangement, even where it comprises only a single opening 225, is sized and shaped to provide at least two simultaneous (independent) flowpaths separated in space, to thereby allow the independent passage of liquid into the teat section 115 and air out of the teat section 215 during filling. An elongate hole makes this easier, and may provide greater spatial separation between these flow paths, potentially enabling the flow of each (air and liquid) to be increased.

[0228] A further possible embodiment is shown in FIG. 4.

[0229] This is again the same in all respects as that of FIG. 2 or 3, except that in this case the passageway arrangement 215 comprises a pair of two openings 225a, 225b, spaced close together. Preferably the openings are through-holes in the partitioning component.

[0230] Where two openings are provided, these may each be provided at a smaller diameter compared to the single opening of the embodiments of FIGS. 2 and 3 without loss of functionality.

[0231] Preferably the two holes are substantially the same size (e.g. substantially the same cross-section and/or surface area). Substantially means for example with less than 10% or 5% difference in size.

[0232] Providing two separate holes that are close together on the same side of the partition 210 further improves the flow as this arrangement tends to encourage the liquid and air to spontaneously separate in their flows between the two holes, and to therefore respectively flow through different of the holes, especially if the bottle is tilted slightly. In other words, the dual-hole arrangement encourages the two fluid types to ‘choose a side’. Thus, this better ensures spatial separation of the flow paths for air and liquid respectively, since each of these two fluid types is typically flowing selectively through only one of the holes. Thus, flow can be improved.

[0233] It is noted that multiple flowpaths are still provided by the single-hole embodiments discussed above, but depending upon the orientation of the bottle and the levels of the fluid, sometimes these can partially or temporarily interfere. Separate holes can potentially better prevent this from happening.

[0234] However, on the other hand, a single hole may be preferable from a manufacturing perspective, since it is easier and faster to form a single hole than two separate holes. A single hole may also be easier to clean, thus improving user convenience and hygiene.

[0235] FIG. 5 shows a further example embodiment.

[0236] This embodiment is again the same in all respects as previously described embodiments apart from the configuration of the passageway arrangement 215. In this embodiment, the passageway arrangement comprises a single opening 225, but formed by a cut-out section, cut into the side edge of the partitioning component 120. The cut-out in this example has an arcuate boundary on one side, extending concavely into the body of the partitioning component 210.

[0237] The cut-out thus takes the form of indent in the rim of the partitioning component, the indent defining the opening 225, with the opening being bounded on one side by the remainder of the partitioning component, and on the other side by part of the inner wall of the bottle 100 (when in position, during use).

[0238] Thus, in this embodiment, the single opening 220 is formed at the very side edge of the partitioning component itself. It is thus located maximally off-center, in a maximally eccentric position. This therefore maximizes the area of the partitioning component which is fluid impermeable, thus maximizing the area which can act to retain liquid inside the teat section 115 when the bottle is in a horizontal position (shown in FIG. 5c for example). More specifically, it maximizes the diametric height of the section of the partitioning component which acts as a retaining wall against liquid escape from the teat in the horizontal position. This means, the teat can continue to be maintained filled even with the liquid level in the container section 125 at a very low level.

[0239] Although the example of FIG. 5 has a single opening formed as a cut-out, in further embodiments, multiple openings 225 may be provided, each similarly formed from a cut-out into the side wall of the partitioning component.

[0240] A further set of embodiments is illustrated in FIG. 6.

[0241] In this set of embodiments, the passageway arrangement 215 comprises a plurality of openings 225, and wherein the openings are arranged to be at different heights along a longitudinal axis of the bottle.

[0242] An example is illustrated in cross-section in FIG. 6a, in plan view in FIG. 6b and in perspective view in FIG. 6c.

[0243] In this example, the passageway arrangement 210 comprises two openings 225a, 255b, a boundary of a first 225a of the openings arranged to be at a first height, and a boundary of a second of the openings 225b arranged to be a different, greater height. Height in this case means a height along a direction of the longitudinal axis 145 of the feeding bottle 100 or a height along an axis normal to a plane defined by the partitioning component. Thus, in this example, the first 225a of the openings is arranged to be closer to the teat 110 and the second of the openings 225b s arranged to be closer to the base end of the container 120.

[0244] The difference in the opening heights is facilitated in this example by providing a partitioning component 210 having an extruded portion 226 on one side, the extruded portion having a upper surface which is at a raised height relative to the upper surface of the other side of the partitioning component (the flat side), and wherein the second (higher) 225b of the openings being formed in the upper surface of the extruded portion 226.

[0245] The first (lower) 225a opening is formed in the non-extruded, flat side of the partitioning component 210.

[0246] Providing openings at different heights further assists with the provision of the dual flow paths for simultaneous passage of air and liquid. This is because the different heights further encourages the two fluid types (air and liquid) to selectively flow each through a different one of the holes. It in other words further encourages the two fluid types to ‘choose a side’ through which to flow. Due to the different heights, this happens spontaneously without the need to tip the bottle to initiate the flow separation. Thus, this better ensures separation of the flow paths for air and liquid respectively, since each of these two fluid types typically flows selectively through only one of the holes. Thus, flow can be improved.

[0247] Another example of this set of embodiments is illustrated in FIG. 5d. This example also comprises a passageway arrangement 215 comprising two openings 225a, 225b, with the two openings elevated at different heights along the direction of the longitudinal axis 145 of the bottle (when the bottle is assembled with the partition arrangement 210 in place). In this example, the upper surface of the partition arrangement 210 is contoured or profiled so as to define a slope which inclines from one portion of the outer boundary of the partitioning component 210 to an elevated height, and wherein one of the openings 225b is formed in the upper surface at said elevated height. A first 225a (lower) of the two openings 225a is formed in a lower, flat section of the partitioning component upper surface, with the sloping, contoured part surrounding this flat part, with a vertical wall bridging the gap in heights between two regions.

[0248] The two openings in this example are directly adjacent in a radial or planar dimension, but separated height-wise (i.e. in a longitudinal or axial dimension). The height distance between the two holes is greater than the distance between them in the radial or planar direction.

[0249] The sloping of the upper surface away from the raised opening 225 in this example effectively provides a funnel shape which encourages flow of air out of the teat though the upper opening 225 when the bottle is held in the upside-down position during filling (as in FIG. 6a), and encourages flow of liquid out of the teat section when held upright during emptying of the teat section after feeding. The sloping could alternatively be provided in the inverted direction to instead encourage liquid flow in to the teat during filling and flow of air into the teat during emptying.

[0250] The multiple heights can be provided by the passageway arrangement, even in the case that it comprises only a single opening.

[0251] One example is shown in FIGS. 7a-7c for example. Again, this embodiment differs from previous embodiments only in respect of the passageway arrangement 215.

[0252] In this example, the passageway arrangement 215 comprises a single opening 225, and wherein a boundary of this opening has a split height. In particular, one side 227 of the opening is at a first height along the direction of the bottle longitudinal axis, and the other, opposing, side 228 is at a second, greater height.

[0253] In this particular example, the surface of the partitioning component 210 is arranged to slope or curve upwards to meet said higher side 228.

[0254] Due to the different heights of the two sides 227, 228 of the opening 225 boundary, this again encourages (spatial) separation of the flow paths of the air 160 and liquid 150, but without the need to provide more than one opening.

[0255] Preferably, the single opening 225 is elongate (as shown in FIG. 7b), which provides greater flow area for the fluids, which better facilitates the spatial separation of the flow paths for the air and liquid respectively.

[0256] A further example embodiment is shown FIG. 8. This is the same in all respects as each of the previous embodiments, except for the arrangement of the fluid passageway arrangement 215.

[0257] In this embodiment, the passageway arrangement 215 comprises a single opening 225. The single opening in this example is elongate. The surface of the partitioning component 210 is arranged to slope or curve downward away from all sides of the opening 225 to thereby define a funnel shape around the opening 225.

[0258] The funnel shape provides a dual function: during filling of the teat (FIG. 8a) it encourages the air to flow out of the teat; during emptying of the teat (by tipping the bottle 100 upright), it encourages all of the liquid left in the teat section 115 to flow out of the teat section. It thus provides a fluid guidance function.

[0259] The sloping could alternatively be provided in the inverted direction to instead preferentially encourage liquid flow in to the teat during filling and flow of air into the teat during emptying.

[0260] A funnel shape such as this can be added to any one or more of the openings in any of the other embodiments described above to provide this fluid guidance function.

[0261] In accordance with any of the above described embodiments, the following represent possible advantageous features which may be incorporated. These features may be applied or incorporated to any embodiment of the invention described in this disclosure.

[0262] In accordance with some examples, the region of the partitioning component 210 containing the passageway arrangement 215 may be limited in its area so that it extends from an outer boundary of the element across a radial distance of no greater than one quarter of a diameter, D, of the partitioning component, and preferably less than one fifth of the diameter, and more preferably less than one sixth of the diameter, and even more preferably less than one tenth of the diameter. The smaller the diametric height of the section containing the openings 225, the greater the fluid retention capability within the teat section 125 during use.

[0263] For example, the region containing the passageway arrangement may be segment shaped section, having a segment saggita of no greater than one quarter of a diameter of the partitioning component, and preferably less than one fifth of the diameter, and more preferably less than one sixth of the diameter, and even more preferably less than one tenth of the diameter.

[0264] In advantageous examples, the region of the partitioning component 210 containing the passageway arrangement 215 may extend across less than one quarter of the total perimeter of the partitioning component, and preferably less than one fifth of the perimeter and preferably less than one sixth of the perimeter.

[0265] For example, the partitioning component may have a circumference, and the region containing the partitioning component may define a segment of the partitioning component, and wherein an arc length of the segment is less than one quarter of the total circumference/perimeter of the partitioning component, and preferably less than one fifth of the circumference and preferably less than one sixth of the circumference.

[0266] According to one aspect of the present invention, there may be provided just a partitioning component 210 in accordance with any of the embodiments outlined above, and wherein this component is configured to be affixed or otherwise fitted to the bottle 100 during assembly of the bottle. In some cases for example, the partitioning component is a membrane or disk component which sits in a receiving cavity or a supporting ledge at an interface between the container component 120 and the teat component 110, so that it can be simply placed in position during assembly of the bottle 100.

[0267] In accordance with a further aspect, there may be provided a feeding bottle 100 comprising:

[0268] a teat component 110, and a container component 120, the components being attachable to one another to form an enclosed bottle volume therein, the bottle volume extending longitudinally from a base end of the bottle, formed by the container component, to a top end of the bottle, formed by the teat component; and

[0269] a partitioning component 120 in accordance with any example or embodiment outlined above or described below, or in accordance with any claim of this application.

[0270] In one set of embodiments, the partitioning component may be formed integrally with either the teat component or the container component.

[0271] In another set of components, the feeding bottle may include attachment means by which the partitioning component is retained in position in the bottle.

[0272] Although in examples, described above, the partitioning component is formed of a single unitary body, this is not essential. In accordance with one or more further embodiments, the partitioning component may comprise a plurality of parts, which may be connected, or may be spaced apart. This may be the case for example in examples in which the bottle container and and/or teat is shaped such that the internal volume is asymmetric in cross-sectional shape along at least one region, or for instance divides into multiple channels. Here, to provide a partitioning component which successfully fluidly divides the bottle volume, the partitioning component must likewise be formed asymmetric or formed of multiple parts to span the different channels or regions of the internal volume.

[0273] Furthermore although in the embodiments discussed above, the passageway arrangement is formed at a location offset from a center of the partitioning component, on one diametric side of the partitioning component, this is not essential. More broadly, the passageway arrangement may be arranged such that when the component is in position in the bottle, the passageway arrangement is offset from a central axis of the bottle, e.g. a central longitudinal axis of the bottle, on one diametric side of the bottle.

[0274] More preferably, the passageway arrangement may be offset from a central axis of the teat component specifically, on one diametric side of the teat section 115 of the volume. In this way, the volume which can be retained in the teat section by the non-permeable part of the component is maximized.

[0275] To illustrate this, one example is schematically depicted in FIG. 9. In this example, the container component 120 and the teat component 110 are joined together via-an off-center coupling, which forms a narrowed-width neck section of the bottle volume which is off-center with respect to the longitudinal axis 145 of the overall bottle volume. This narrowed width section is at the junction between the container component 120 and the teat component 110. The partitioning component 210 is located at the junction between the container component 120 and the teat component 110, positioned within the narrow width neck section. It comprises a passageway arrangement 215 which is approximately central within the partitioning component itself, but which is offset from a central longitudinal axis of the bottle volume 145, and more particularly, is offset from a central axis 147 of the treat component 110, on one diametric side of the teat section of the bottle internal volume. (In this example the teat volume central axis 147 and overall bottle central axis 145 are aligned, but this may not always be the case)

[0276] In some embodiments, the partitioning component may be an integral part of the teat component or container component.

[0277] Examples will now be described in accordance with a further aspect of the invention. Features of these embodiments may equally be applied or combined into any of the embodiments discussed above.

[0278] In accordance with a further aspect of the invention there is provided an arrangement for a feeding bottle, the feeding bottle comprising a teat component 110, and a container component 120, which together define a bottle volume extending longitudinally between a base end of the container component, and a top end of the teat component. The bottle volume may be understood as having a longitudinal axis extending from said base end to said top end, and a diametric dimension extending orthogonal to the longitudinal axis.

[0279] The arrangement comprises an internal element 310 for positioning inside the bottle volume, and a protruding element 320 arranged for extending from the internal element to an outside of the bottle when the bottle is in an assembled state, with the internal element in position, for providing an interconnection between inside and outside of the bottle.

[0280] The internal element is for locating at a position inside the bottle, either inside the container or inside the teat component. It is for being fixed in position. The internal element effectively provides an internal anchoring element for holding the interconnect component in place. It may be an integral part of the container or the teat component or may be a separate element arranged to be fixed in position in use.

[0281] The bottle volume is defined at least in part by respective internal cavities of the teat component and container component.

[0282] The arrangement provides an interconnection between the bottle volume inside the bottle, and the outside of the bottle.

[0283] The internal element is preferably configured to be positioned in the bottle such that it is exposed to (i.e. it is arranged to come into contact with) and/or has fluid, mechanical, electrical and/or data communication access to the bottle volume, i.e. the contents of the bottle volume. Preferably, it is exposed to (i.e. it is arranged to come into contact with) and/or has fluid, mechanical, electrical or data communication access to both the teat section of the volume and the container section of the volume. This way interconnection is facilitated between the outside of the bottle and both the teat and container sections of volume.

[0284] Here, reference to teat section and container sections of the volume can be understood as follows. A teat section of the volume may extend from the top end of the bottle to the internal element, and a container section may extending from the internal element toward the base of the bottle.

[0285] FIGS. 10-12 show different views of one example arrangement 300 according to one or more embodiments. The arrangement comprises an internal element 310 which is substantially disc shaped and a protruding element 320 which outwardly extends from the internal element 310 substantially normal to the plane of the disc shape of the internal element. In this particular example, the internal element is configured to be positioned in use at an interface or junction between the container component 120 and the teat component 110. It may rest atop, or abut, an upper edge or rim of the container component. In this way, when the bottle is assembled, it is arranged exposed to both the teat volume above it and the container volume below it. The arrangement 300 can thus provide an interconnection between the outside of the bottle and both the teat volume 115 and the bottle volume 125.

[0286] The feeding bottle 100 comprises a coupling arrangement 340 for coupling the teat component 110 to the container component 120, and wherein the protruding element 320 is arranged to extend to an outside of the bottle via passage through the coupling arrangement. In this example, the coupling is a screw coupling 342.

[0287] In particular, the protruding element passes between interfacing parts or surfaces of the coupling arrangement. The interfacing parts are the outer rim surface of the container component and the inner rim surface of the teat component 110.

[0288] In this example, the protruding element 320 follows a hook or flap shape for permitting the member to extend over the top of an upper edge of the container component 120, to permit passage of the protruding element to the outside of the container component.

[0289] It extends over the top edge and down at least a portion of the outside wall of the container component.

[0290] A rounded disc end cap 380 is provided on the external portion of the protruding element 320 which extends substantially parallel with a longitudinal axis of the bottle 100.

[0291] A stem part 360 of the protruding element 320 extends over a top edge of the container 120 component, down an outside of the container component wall through a break formed in the screw threads 344 on the container component, before turning and extending outwardly away from the wall (e.g. substantially orthogonally from the stem) to define a short tail section 370. This tail section then is connected to the end disc cap element 380, a plane of the disc cap 380 extending substantially perpendicular to the direction of the tail section 370.

[0292] When the bottle is assembled with the teat component 110 attached to the container component 120 as shown in FIG. 12, the disc end cap 380 is shaped and sized so that it protrudes vertically above a lower-most (bottom) edge of the teat component 110, so that it spans a junction or interface line between the teat component 110 and the container component 120.

[0293] The protruding element 320 provides a visual indication of an orientation of the internal element 310 of the arrangement 300 which is visible from outside the bottle when the bottle is assembled. It also provides a tactile indicator (by virtue of the disc end cap element 380), meaning that an orientation of the internal element 310 can be sensed just by feeling the position of the end cap around the outer circumference of the bottle. This can be done even in low light.

[0294] The protruding element is connected with a fixed position relative to the internal element, meaning that the orientation of the internal element is directly coupled with a position of the protruding element at an outside of the bottle.

[0295] In some embodiments, the internal element may carry or be coupled to a further functional element also for location in the bottle volume when assembled, and wherein the protruding element has a fixed position relative to the further functional element, such that an external portion of the protruding element may provide a visual and/or tactile indication of the position (e.g. orientation) of the functional element inside the bottle. By way of example, the further functional element might be any one or more of: a passageway arrangement formed in the internal element (as in examples discussed above) for permitting passage of fluid across the element; a valve, an air-channeling element, a sensor, or even an electrical component such as a heater or mixer.

[0296] The internal element is adapted to provide a support function, for holding the protruding element in a fixed position relative to the container component and teat component.

[0297] In accordance with one set of embodiments, the internal element may be a partitioning component for dividing an internal volume of the bottle. It may be a partitioning component in accordance with any of the examples outlined above or described below or in accordance with any claim of this application. Thus, the features described herein pertaining to the arrangement comprising internal element and protruding element may be understood to be applicable and fully compatible with any of the example partitioning component embodiments described above.

[0298] For example, in the example shown in FIGS. 10-12, the internal element 310 is also a partitioning component for the bottle, comprising a passageway arrangement 215 confined to one diametric side of the internal element 310, offset from a center of the internal element.

[0299] Where the internal element takes the form of a partitioning component, advantageously the protruding element 320 may be for providing a visual indication of an orientation of the internal element 310 relative to the bottle. This allows an orientation of the passageway arrangement 315 to be determined from the outside of the bottle, which enables a user to know in which axial orientation the bottle should be held in order to ensure that the passageway arrangement is positioned at a gravitationally lowest point (see discussion above). For example, the protruding element 320 may be arranged diametrically opposite the passageway arrangement, so that a user knows that the external part of the protruding element should be facing vertically upward in order for the passageway arrangement to be pointing downward. An externally exposed part of the protruding element thus provides a visual and tactile indicator of an orientation of the internal element.

[0300] A further example arrangement in accordance with one or more embodiments is shown in FIG. 13. This example is similar to that of FIGS. 10-12, except that the protruding portion 320 does not comprise a disc end cap which extends substantially parallel to the longitudinal axis of the bottle. Instead, the stem 360 of the protruding portion ends in the tail section 370 which outwardly extends from the stem section 360 in a direction away from the bottle container 120, either substantially perpendicular to the extension direction of the stem section 360 or obliquely with respect to this direction, e.g. obliquely in a direction downward toward a base of the bottle.

[0301] A further example arrangement in accordance with one or more embodiments is shown in FIGS. 14-17. FIGS. 14 and 15 show cross-sectional views of the example arrangement 300. FIG. 16 shows a perspective view of the arrangement fitted in position within a teat component 110 of the bottle. FIG. 17 shows a perspective view of the external section of the protruding element 320 of the arrangement 300, as visible from outside the bottle when the bottle is fully assembled with the arrangement in position.

[0302] This example is similar to those of FIGS. 10-13 described above, except for the very end part of the protruding element 320, at the end of the stem 360 and tail 370 section. Instead of ending in a disc end cap 380 as in FIGS. 10-12, the protruding element, at the end of the tail section 370, turns to extend in a direction upward, substantially parallel with the longitudinal axis of the bottle, toward a top end of the bottle (toward the top of the teat component. This upward extending section thereby forms an upstanding tab member 420.

[0303] The external part of the protruding element thus defines a U-shape. The U-shape in this example is shaped to bend down and around and back up a lower edge or rim 112 of the container component, so that, when the bottle is fully assembled, the lower edge of the wall of the container component is effectively accommodated within the U-shape defined by the external part of the protruding element 320.

[0304] A further example arrangement in accordance with one or more embodiments is shown in FIGS. 18 and 19.

[0305] In this example, the internal element 310 is configured to be positioned inside an upper region of the teat component. The protruding element extends downwardly from the plane of the internal element and at a slight oblique angle such that it may pass through interfacing surfaces of the coupling between the teat component 110 and the container component 120 situated below. The protruding element is a flat or laminar element to allow it to fit through the coupling arrangement. The protruding element comprises a stem section 360. The stem section comprises a narrow width portion 360a which is arranged to pass though the coupling between the teat component and the container, and a wider width portion 360b which is arranged to be exposed outside of the bottle when assembled, and at a level below the screw coupling. The larger width portion provides a visual and tactile indicator element for example.

[0306] The protruding element 320 further comprises a tail section 370 which extends obliquely away from the wider width portion 360b of the stem.

[0307] In accordance with each of the examples of FIGS. 10-19, the internal element comprises a disc element shaped for traversing a cross-section of the bottle volume.

[0308] In accordance with each of the examples of FIGS. 10-17, the internal element is configured to be positioned at an interface or junction between the container component and the teat component of the bottle. However, this is not essential, and it may be position at any location along the bottle volume. By way of example, in the example of FIGS. 18 and 19, the internal element 310 is positioned inside the teat component 110 and the protruding element is arranged to extend down from the teat component through a passageway in the screw ring coupling to the outside of the bottle.

[0309] In accordance with each of the above examples, the protruding element 320 of the arrangement 300 is configured to extend from the inside to the outside of the bottle via a coupling arrangement 340, 342 of the bottle. In each of the illustrated examples, it extends through a space formed between interfacing parts (faces) of the coupling means. The coupling arrangement in this case is between the container component 120 and the teat component 110, and comprises a screw coupling comprising a pair of complementary threaded areas 344, 346 provided on outside and inside rim surfaces of the container 120 and teat 110 component respectively. The thread coupling is shaped to define a space or channel to accommodate passage of the protruding element 320 between the interfacing rim surfaces, through the coupling arrangement to an outside of the bottle.

[0310] In particular examples, at least one of the thread portions 346 may be provided circumferentially discontinuous to thereby define at least one circumferential gap 352 in the threads, the gap arranged to accommodate passage of the protruding element. In preferred embodiments, only one of the thread portions is provided discontinuous and the other is continuous.

[0311] This example configuration is shown most clearly in FIG. 16. Here, the thread portion 346 of the teat component 110 is shown. The thread portion is provided on an inner surface of the teat component outer wall, adjacent a lower rim of the teat component. In this example, the thread portion is circumferentially discontinuous around the circumference of the teat component rim. The discontinuous thread portions thus form multiple circumferentially spaced thread sections 350a, 350b, 350c, 350d (latter not visible), separated by gaps 352. The protruding element 320 extends through one of the gaps or breaks 352 formed in the threads. It is noted that the complementary thread portion on the container component may be continuous around the circumference of the container rim. In this way, the threads of the teat component are always able to thread couple with the container component threads regardless of the orientational position of the teat component.

[0312] One of the thread portions (the one comprised by the container component) is preferably adjacent an upper rim of the container component, and wherein the internal element is configured to be positioned within the bottle volume at a location at or above said upper rim of the container component, and wherein the protruding element is configured to downwardly extend over said thread portion. This thread portion may be continuous. The protruding element 320 is accommodated through a gap formed in the container component threads for example.

[0313] Although in each of the examples described above, the provided arrangement 300 takes the form of a partitioning component for the feeding bottle, this is only one example function for the arrangement, and is not essential to the general concept. In general, the arrangement is configured simply to provide an interconnection between the inside and outside of the bottle. This can be useful, as discussed above, for facilitating external visual and/or tactile indication of an orientation of the internal element, by providing that the protruding component 320 provides a physical connection between the internal element 310 and the outside of the bottle.

[0314] In particular, the protruding element has a fixed position relative the internal element 301, which means that changes in the orientation of the internal element (inside the bottle) as the bottle is rotated are directly coupled to changes in a position of the protruding element at the outside of the bottle (e.g. the indicator element). For example the angular position of the protruding element around the bottle changes.

[0315] In some embodiments, the internal element may carry or be coupled to a further functional element also for location in the bottle volume when assembled, and wherein the protruding element has a fixed position relative to the further functional element, such that an external portion of the protruding element may provide a visual and/or tactile indication of the position (e.g. orientation) of the functional element inside the bottle. By way of example, the further functional element might be any one or more of: a passageway arrangement formed in the internal element (as in examples discussed above) for permitting passage of fluid across the element; a valve, an air-channeling element, a sensor, or even an electrical component such as a heater or mixer.

[0316] Additionally or alternatively, the protruding element may be configured to provide an electrical and/or data connection between the inside and the outside of the bottle.

[0317] In particular, in some embodiments, the protruding element 320 may incorporate an electrically conducting element for providing an electrical interconnection between the inside and outside of the bottle. An electrical connection may be useful for supplying a power to an internal electrical component such an internal heater, and internal mixing mechanism, an internal light or any other electrical component.

[0318] Additionally or alternatively, in some embodiments, the protruding element 320 may comprise a data-carrying line for providing a data interconnection between an inside and outside of the bottle. A data connection may be useful for receiving data from one or more sensors such as a temperature sensor for instance.

[0319] Additionally or alternatively, in some embodiments, the protruding element may incorporate a fluid passageway (e.g. air and/or liquid) from the inside the bottle to outside the bottle. It may for instance include an integrated fluid conduit for facilitating this. This could be useful for example for diverting air out of a certain section of the bottle volume, or providing an overspill outlet for instance.

[0320] The bottle may be provided in combination with the arrangement 300 with internal element and protruding element 320, or the arrangement 300 may be provided by itself for fitting into a bottle.

[0321] Examples will now be described in accordance with a further aspect of the invention. Features of these embodiments may equally be applied or combined into any of the embodiments discussed above

[0322] In accordance with a further aspect of the invention there is provided an internal element 310 for a feeding bottle, the feeding bottle comprising a teat component 110, and a container component 120, which together define a bottle volume extending longitudinally between a base end of the container component, and a top end of the teat component, the bottle volume having a longitudinal axis extending from said base end to said top end,

[0323] the internal element 310 comprising a disc element 620 configured to be positioned within the bottle volume extending transverse the longitudinal axis, and further comprising one or more tab elements 640 protruding from an outer periphery 630 of the disc element for being received between interfacing parts of a coupling arrangement 340, 342 of the bottle.

[0324] An example internal element 310 in accordance with one or more embodiments is shown schematically in FIG. 20 and FIG. 21, in cross-section and plan views respectively. The internal element 310 comprises a disc shaped portion (disc element) 620 and further comprises a set of one or more tab elements 640. In the example of FIG. 20 and FIG. 21, a plurality of tab elements 640a-640d is provided. In the particular example illustrated, four tab elements are provided. However, any other number of tab elements may be provided. Preferably the one or more tab elements are arranged in an annularly symmetric pattern or configuration around the perimeter of the disk element 620.

[0325] The one or more tab elements 640 are configured for being received between interfacing parts of a coupling arrangement of the bottle, for example a coupling arrangement between the container component and the teat component. The function of this is to provide support to the internal element against downward forces imposed by the coupling between the components of the bottle which might otherwise force the internal element downward, e.g. buckling, deforming or displacing it. The tab elements being trapped in the coupling arrangement provides a resistance against such forces.

[0326] In the particular example shown in FIG. 22, the tab elements 340 are for being received between interfacing parts of a screw coupling arrangement 342 which couples the teat component to the container component.

[0327] The tab components 640 are configured to be received between threads of the screw coupling.

[0328] Although in the example shown in FIG. 21, the disc element portion 620 of the internal element 310 takes the form of a continuous planar disc, in other embodiments, it may take the form of an annular disk (i.e. defining a ring shape). The particular shape may depend upon the function for which the internal element is used 310.

[0329] There are different options for the configuration and function of the internal element 310.

[0330] In some examples, it may be a partitioning component for fluidly dividing an internal volume of the bottle and mediating flow of fluid between them.

[0331] For example, it may be a partitioning component for fluidly dividing the bottle volume into two longitudinal sections, a teat section 115 extending from the top end of the bottle to the partitioning component, and a container section 125 extending from the partitioning component toward the base of the bottle. It may for example be a partitioning component in accordance with any of the examples described above or below, or in accordance with any claim of this application. Thus any of the features described herein in relation to the internal element according to this aspect of the invention may be applied or incorporated into any of the example partitioning component embodiments outlined above.

[0332] By way of example, FIG. 22 shows one example internal element 310 in accordance with one or more embodiments of the present aspect which takes the form of a partitioning component, and comprises a fluid passageway arrangement 215 comprising one or more openings 220 for permitting flow of fluid across the partitioning component.

[0333] However, the internal element 310 can take different forms for performing different functions.

[0334] By way of example, FIG. 23 shows an example internal element 310 in accordance with one or more embodiments of this aspect which comprises a protruding element 320 arranged for extending from the internal element 310 to an outside of the bottle when the bottle is in an assembled state, for providing an interconnection between the inside and outside of the bottle. For example, the internal element may thus take the form of an internal element of an arrangement 300 in accordance with any of the example embodiments discussed above in relation to FIGS. 10-19, or as set out in any claim of this application. Thus, features of the presently described internal element 310 may be applied or incorporated into any of the example arrangement 300 embodiments discussed above.

[0335] For example, tab elements 640 in accordance with embodiments of the present aspect are shown as included on the internal element 310 of the example of FIG. 10-12 (see FIGS. 10 and 11), and also on the internal element of FIG. 13. However, the tab elements are not essential in those embodiments, and may be omitted in variations.

[0336] Returning to the example of FIG. 23, the internal element 310 in this example comprises the protruding element 320 and further comprises a set of tab elements 640a-c arranged protruding from the outer periphery of the disc element part 620 of the internal element 310. Three tab elements are provided in this example but more or fewer may be provided in variations on this example.

[0337] In the example of FIG. 23, the disc part 620 of the internal element 310 incorporates a fluid passageway arrangement 215 for permitting passage of fluid across the element. The internal element 310 in this example may thus perform the function of a partitioning component as discussed above. However, in other examples, an internal element can be provided with the tabs 640 and protruding element 320 but without being for the function of providing a partitioning component. For example, the disc element 620 part of the internal element could be annular (ring shaped) in form, so that fluid can effectively flow freely across the element, so it does not fluidly partition the volume.

[0338] The disc part 620 of the internal element 310 defines a plane. The tab elements 640 in this example extend obliquely with respect to this plane. In particular, they extend in a direction obliquely downward, toward a base of the container component when the internal element is in position. This is visible for example in FIG. 22 and FIG. 23, and also in the schematic cross-sectional view of FIG. 20.

[0339] This oblique shape can provide greater stability to the internal element since it effectively provides a hook shape for the element to hook over a top edge of the container component, or to hook inside a coupling arrangement within which it is received.

[0340] In accordance with one or more embodiments, the disc 620 of the internal element 310 may define a plane, and wherein the one or more tab elements are resiliently bendable in a direction oblique to the plane.

[0341] The one or more tab elements 640 may be formed of a resilient or elastic material in some examples, for example an elastomeric material. In some examples, an outer rim portion of the internal element 310 may be formed of a resilient or elastic material, for example an elastomeric material.

[0342] In accordance with the example of FIG. 22 and FIG. 23, the internal element 310 is configured to be positioned at an interface or junction between the teat component 110 and the container component 120 of the bottle. The internal element is illustrated placed in this position in FIG. 22 for example.

[0343] In accordance with one or more advantageous examples, the one or more tab elements 640 may each comprise one or more protrusions or bosses formed on at least one face of the tab element. This is illustrated in FIG. 24 for example. FIG. 24 shows an underside surface of the internal element 301 illustrated in FIG. 13. Only half of the internal element 301 is shown. In this example, each of the tab elements 640 comprises a plurality of bosses or balls 720 which protrude from an underside face of the tab elements. These protrusions provide additional friction for increasing a friction between the tab elements and the coupling arrangement within which they are received. This helps with even more securely retaining the internal element 301 in position, against movement, once the bottle is assembled with the tab elements 640 received within the coupling arrangement 340, 342.

[0344] In particular examples, the disc part 620 of the internal element may define a plane, and the tab elements 640 may protrude obliquely with respect to this plane, for example as illustrated in the example of FIG. 24 (and Fig.23). Thus in this case, the tab elements may effectively hook over a top rim edge of the container component. By providing the optional protrusions or bosses 720 on the underside of the tab elements 640, friction is increased and the tab elements may provide at least partial clamping of the internal element to the container component. This prevents the internal element being dragged along around the screw ring coupling 342 when the teat component is screwed onto the container component. Hence they provide a frictional resistance against axial rotation of the internal element.

[0345] As mentioned above, in the particular example shown in the Figures, the tab elements 640 are for being received between interfacing parts of a screw coupling arrangement 342 which couples the teat component to the container component.

[0346] The screw coupling 342 comprises complementary thread portions 344, 346 provided on outer and/or inner surfaces of the teat component and container component respectively, one of the thread portions being located adjacent an upper edge of the container component 120. The thread portions may be thread rings, or portions of a thread ring.

[0347] The thread portions 344 extend discontinuously around the perimeter of at least one of the teat component 110 and container component 120, to form multiple circumferentially spaced thread sections 350, and wherein the internal element 310 comprises a respective tab element 640 for each of the thread sections of the coupling arrangement.

[0348] This example configuration of threads is shown for example FIG. 16. Here, the thread portion 346 of the teat component 110 is shown. The thread portion is provided on an inner surface of the teat component outer wall, adjacent a lower rim of the teat component. In this example, the thread portion is circumferentially discontinuous around the circumference of the teat component rim. The discontinuous thread portions thus form multiple circumferentially spaced thread sections 350. This arrangement is also visible in FIG. 19.

[0349] The thread portion 344 of the container component 120 may be continuous, so that the discontinuous thread portion 346 of the teat component 110 may couple to it regardless of orientational position.

[0350] Although in each of the examples discussed above, a plurality of tab elements are provided, in other example just one tab element may be provided. By way of one illustration, the example arrangement of FIG. 18 (discussed above) provides one example of an internal element 310 which comprises a single tab element 420. The single tab element extends annularly all the way around the circumference of the disc element portion of the internal element 310. It thus provides a circumferentially symmetric tab arrangement. The internal element of FIG. 18 is part of an arrangement 300 comprising the internal element and a protruding element 320 and has been discussed above.

[0351] The single tab 640 element may be formed of a flexible or elastomeric material to permit it to flex to be received within the coupling 340, for example between threads of a screw coupling 342.

[0352] In examples in which a plurality of tab elements 640 is provided, preferably the tabs are positioned in diametrically opposing pairs around the rim of the disc element. This provides symmetrical support for the disc element against buckling.

[0353] Variations to the disclosed embodiments can be understood and effected by those skilled in the art in practicing the claimed invention, from a study of the drawings, the disclosure and the appended claims. In the claims, the word “comprising” does not exclude other elements or steps, and the indefinite article “a” or “an” does not exclude a plurality.

[0354] The mere fact that certain measures are recited in mutually different dependent claims does not indicate that a combination of these measures cannot be used to advantage.

[0355] If the term “adapted to” is used in the claims or description, it is noted the term “adapted to” is intended to be equivalent to the term “configured to”.

[0356] Any reference signs in the claims should not be construed as limiting the scope.
