DETAILED DESCRIPTION

(12) Although the embodiments of the body liquid receptacle and multi-liner assembly and corresponding parts thereof consist of certain geometrical configurations as explained and illustrated herein, not all of these components and geometries are essential and thus should not be taken in their restrictive sense. It is to be understood, as also apparent to a person skilled in the art, that other suitable components and cooperation thereinbetween, as well as other suitable geometrical configurations, may be used for the body liquid receptacle and multi-liner assembly, as will be briefly explained herein and as can be easily inferred herefrom by a person skilled in the art. Moreover, it will be appreciated that positional descriptions such as above, below, left, right and the like should, unless otherwise indicated, be taken in the context of the figures and should not be considered limiting.

(13) In the following description, the same numerical references refer to similar elements. Furthermore, for the sake of simplicity and clarity, namely so as to not unduly burden the figures with several reference numbers, not all figures contain references to all the components and features, and references to some components and features may be found in only one figure, and components and features of the present disclosure which are illustrated in other figures can be easily inferred therefrom. The embodiments, geometrical configurations, materials mentioned and/or dimensions shown in the figures are optional, and are given for exemplification purposes only.

(14) Referring now to the drawings and, more particularly referring to FIGS. 1 and 2, there is shown a body liquid receptacle assembly 20 including a multi-liner assembly 24 engaged with a body liquid receptacle 22 (shown separately in the exploded view of FIG. 3). In the illustrated embodiment, the multi-liner assembly 24 is engaged with the body liquid receptacle 22 such that it completely covers upper and side portions of body liquid receptacle 22, thereby protecting the body liquid receptacle 22 for sanitary purposes.

(15) In an embodiment, the multi-liner assembly 24 is detachably engaged with the body liquid receptacle 22. As shown in the exploded view of FIG. 3, the body liquid receptacle 22 defines a body liquid receiving cavity 26. In the present embodiment, the cavity 26 is partially closed, in that it includes a bottom wall 32 with apertures 38 defined therein. However, it should be appreciated that in other embodiments, the cavity can be opened in a bottom thereof (i.e. bottomless, without a bottom wall 32), or closed (i.e. it includes bottom wall 32 without apertures 38). In the engaged configuration, the multi-liner assembly 24 at least partially lines the body liquid receiving cavity 26 to receive and contain body liquids received therein, as will be described in more details below. In the embodiment shown in FIGS. 1 and 2, the multi-liner assembly 24 entirely lines the body liquid receiving cavity 26, and entirely covers exterior surfaces of the body liquid receptacle 22 on a top side thereof.

(16) Referring again to FIG. 3, in the embodiment shown, the body liquid receptacle 22 is a bedpan with a receptacle body 28 having a peripheral wall 30 and the bottom wall 32 together defining the cavity 26, and a seat member 34 extending peripherally outwardly from an upper edge of the peripheral wall 30. In the embodiment shown, the seat member 34 peripherally surrounds the cavity 26. However, in an alternative embodiment, the seat member 34 can partially surround the cavity 26. In the embodiment shown, the seat member 34 peripherally ends with a rim 36, spaced-apart from the peripheral wall 30.

(17) In the embodiment shown, the bottom wall 32 includes a plurality of apertures 38 defined therein. As can be appreciated, these apertures can act as handles to aid in maneuvering the bedpan to position it correctly for use. It is appreciated that the shape, the number and the configuration of the apertures can vary from the embodiment shown. Moreover, as mentioned above, in an alternative embodiment, the bottom wall 32 can be free of apertures or the bedpan can be free of bottom wall 32 closing the cavity 26.

(18) As it will be appreciated, the body liquid receptacle 22 can differ from the bedpan shown in the accompanying figures. In alternative embodiments, the body liquid receptacle 22 can be a urinal device designed and conceived to receive urine or an emesis (vomit) container designed and conceived to receive emesis. It is appreciated that the shape of the body liquid receptacle will vary from the embodiment shown depending on its intended use.

(19) Referring back to FIGS. 1 and 2, there is shown that, in the engaged configuration, the body liquid receptacle 22 is at least partially covered by the multi-liner assembly 24. In the embodiment shown, in the engaged configuration, the multi-liner assembly 24 covers (lines) the cavity 26 and an upper surface of the seat member 34. As mentioned above, the purpose of the multi-liner assembly 24 is to cover an outer surface of the body liquid receptacle 22, and receive and contain body liquid received in the cavity 26 of the body liquid receptacle 22.

(20) Referring to FIGS. 3 and 4, there is shown that, in an embodiment, the multi-liner assembly 24 includes a substantially rigid receptacle engagement support 40 and a plurality of superposed lining units 42a, 42b, 42c, 42u supported by the receptacle engagement support 40. Each one of the lining units 42a, 42b, 42c, 42u includes a liquid impermeable layer or cover 44, such as a plastic film, and an absorbent material layer (or pad) 46 superposed to an upper surface 43 of the lining unit 42, for example on a top side of the impermeable layer 44. As can be appreciated, when the lining units 42a-42u are superposed on one another, an absorbent material layer 46 extends between the liquid impermeable covers 44 of two consecutive lining units.

(21) The receptacle engagement support 40 can have a shape which partially reproduces the shape of the body liquid receptacle 22 to be engageable therewith. For example the rigid support 40 can comprise one or several U-shaped elements 41 configured to engage around an interior or exterior of the receptacle. In other embodiments, the rigid support 40 can alternatively or additionally comprise protrusions and/or apertures for engaging with complementary protrusions and/or apertures in the body liquid receptacle 22. In the embodiment shown, the receptacle engagement support 40 includes a U-shaped element 41 comprising a peripheral wall section 48, a seat member section 50, and a rim section 52. The support 40 is substantially ring-shaped, as it runs continuously along a contour of seat member 34. The support 40 is engageable by superposition to the peripheral wall 30, the seat member 34, and the rim 36 of the body liquid receptacle 22. The peripheral wall section 48 defines a cavity 53 which is aligned with the cavity 26 of the body liquid receptacle 22, when engaged therewith. In the present embodiment, the cavity 53 of the engagement support is open in that it does not include a bottom wall; the engagement support 40 is thus substantially ring-shaped with a U-shaped cross-section. However, it is appreciated that in other embodiments, the cavity 53 can be closed or partially closed by having a bottom wall or part of a bottom wall.

(22) It should be appreciated that other shapes and configurations of the support 40 are also possible. For example, instead of having a U-shaped cross section, support 40 can be a substantially flat ring formed with only seat member section 50. Lining units 42 can be adhered to a top surface of the flat ring, while a bottom surface of the flat ring can be adhered to support 40, for example using an adhesive, or by providing protrusions and/or apertures complementary to protrusions and apertures in seat member 34 of receptacle 22. In other alternative implementations, the support 40 can be a ring formed only with a peripheral wall section 48 or a rim section 52.

(23) In an embodiment, the receptacle engagement support 40 is substantially rigid to maintain its shape when disengaged from the body liquid receptacle 22. For instance and without being limitative, it can be made of plastics or molded fiber or pulp, such as cellulose fiber or cardboard. In some embodiments, the rigid support can comprise a metallic or plastic wire which reproduces a contour of the body liquid receptacle 22. The lining units 42a-42u can thus be attached to the wire, which can maintain a shape of the multi-liner assembly at least until it is engaged with the body liquid receptacle 22 (for example, the wire can maintain the lining units 42 in an open or extended configuration so that it can easily fit over the receptacle 22). In other embodiments, instead of being a continuous ring, support 40 can be made of one or several separate elements for engaging the multi-liner assembly 24 with the receptacle 22. For example, support 40 can comprise one or several clips (or other attachment mechanisms) which are positioned to removably attach to a particular portion of receptacle 22, such as a U-shaped element which only extends along a small segment, or a partial contour of seat member 34. In some embodiments, support 40 can serve to align multi-liner assembly 24 in a proper position on receptacle 22, and the assembly 24 can be engaged with the receptacle using other attachment mechanisms, for example by folding lining units 42 around rim section 36.

(24) In the engaged configuration of the multi-liner assembly 24 with the body liquid receptacle 22, the receptacle engagement support 40 is engaged with the body liquid receptacle 22. In an embodiment, the receptacle engagement support 40 is removably engageable with the body liquid receptacle 22. In the embodiment shown, in the engaged configuration, the peripheral wall section 48, the seat member section 50, and the rim section 52 of the receptacle engagement support 40 are superposed to the respective one of the peripheral wall 30, the seat member 34, and the rim 36 of the body liquid receptacle 22.

(25) As mentioned above, the multi-liner assembly 24 includes a plurality of superposed lining units 42a, 42b, 42c, 42u, which are supported by the receptacle engagement support 40. The lining units 42 are said to be superposed in that they are positioned one on top of the other in a stacked configuration. The liquid impermeable covers 44 of the lining units 42a, 42b, 42c, 42u extend above the receptacle engagement support 40 and are engaged therewith. In the embodiment shown, the liquid impermeable covers 44 cover the peripheral wall section 48, the seat member section 50, and the rim section 52 and extends in the cavity 53 defined by the peripheral wall section 48. Thus, when the multi-liner assembly 24 is engaged with the body liquid receptacle 22, the superposed lining units 42, and more particularly the liquid impermeable covers 44 line (or cover) the cavity 26 of the body liquid receptacle 22.

(26) In the embodiment shown, and also as shown in FIG. 8B, each one of the lining units 42 has an overall bag shape to have a bottom section 45 insertable in the cavity 26 and an upper section 47 which can be wrapped around the seat member section 50. For example, when the lining units 42 are extended as shown in FIG. 3 and FIG. 8B, bottom section 45 can be a central section containing absorbent material 46, and upper section 47 can be an outer peripheral region containing elastic 56 and/or drawstring 57. However, it is appreciated that in an alternative embodiment (not shown), the shape of the liquid receptacle 22 (including the shape of the peripheral wall section 48, seat member section 50, rim section 52, or other sections) can vary from the embodiment shown, and the shape of the lining units 42 can vary accordingly.

(27) The liquid impermeable cover 44 is made of a liquid-proof material, such as and without being limitative a plastic film. In an embodiment, it is sized to at least partially cover the cavity 26 of the body liquid receptacle 22.

(28) Preferably, at least one of the lining units 42 comprises an attachment mechanism for securing the lining unit 42 to the body liquid receptacle 22. In the present embodiment, each one of the lining units 42 has an attachment mechanism which comprises an elastic band 56 in a peripheral region thereof, close to a free edge. More particularly, an elastic band 56 surrounds peripherally each one of the lining units 42. In an alternative embodiment, the elastic band 56 can partially surround peripherally the lining units 42. For instance, the elastic band 56 can include two or more elastic band sections extending along longitudinal sides of each one of the lining units 42. The elastic band 56 is designed to engage the rim section 52 of the receptacle engagement support 40 by maintaining the peripheral region of the lining unit 42 under the rim section 52, as shown in FIG. 4, thereby wrapping the seat member section 50. In the present embodiment, each of the lining units 42 is thus secured to the body liquid receptacle 22 by first engaging with the engagement support 40 via the elastic bands 56, and then to the body liquid receptacle 22 via the engagement support 40. In alternate embodiments, the lining units 42 can secure to the body liquid receptacle 22 directly, for example by omitting the engagement support 40 and wrapping the elastic band 56 directly around the rim section 36 of body liquid receptacle 22.

(29) As can be appreciated, properties of elastic 56, such as its tension, length, position, configuration, etc. can vary to attach more or less tightly to the engagement support 40, to attach it to different sections thereof, or to have the elastic 56 perform other functions. For example, in some embodiments, the elastic band 56 can alternatively or additionally serve as a closure mechanism. For example, the elastic 56 can be tensioned such that impermeable cover 44 retracts to a closed configuration, when the lining unit 42 is removed from the body liquid receptacle 22 or multi-liner assembly 24.

(30) As can be further appreciated, other attachment and/or closure mechanisms can be provided in addition or in place of the elastic 56. For example, attachment and/or closure mechanisms can include tie-downs, hook and loop fasteners, buttons, snaps, strings (such as a drawstring), adhesives, etc. In some embodiments, closure mechanism can simply include a peripheral region of lining unit 42 configured to fold over rim section 52 to secure to support 40, and/or configured to fold over itself to close the lining unit 42.

(31) In the present embodiment, the lining units 42 include a drawstring 57 (or ribbon) in a peripheral region thereof. As illustrated, the drawstring 57 is contained in a sleeve of a peripheral region of the lining units 42, adjacent the elastic 56. Preferably, the drawstring 57 is spaced apart from the elastic 56, such that elastic is provided in an outermost peripheral region of the lining units 42 and the drawstring 57 is in a peripheral region radially inward relative thereto. The drawstring 57 can be pulled out through an opening of the sleeve, causing the peripheral region of the lining unit 42 to bunch up and close. The lining unit 42 can thus be secured to the engagement support 40 and/or the body liquid receptacle 22 by wrapping the lining unit 42 around the support 40 and/or receptacle 22, and pulling the drawstring 57 to tighten the peripheral region of the lining unit 42 under the rim section 52 of support 40. Moreover, when lining unit 42 is removed from the body liquid receptacle 22 or multi-liner assembly 24, the drawstrings 57 can be pulled to move the lining unit 42 into a closed configuration. Although in the present embodiment the lining unit 42 includes both an elastic 56 and a drawstring 57, it is appreciated that in some embodiments the lining unit 42 can include only an elastic 46 or only a drawstring 57.

(32) In other embodiments, the attachment mechanism can comprise an adhesive on an underside or bottom side of some or all lining units 42, or of the multi-liner assembly 24, for attaching the lining unit 42 or multi-liner assembly 24 to a surface onto which the lining unit 42 or multi-liner assembly 24 is superimposed. In an embodiment, the lining units 42 can have a temporary adhesive provided on a bottom surface thereof, for example on a bottom side of the impermeable layer 44, or on a top side of the impermeable layer 46 of a lining unit 42 positioned thereunder. The adhesive is referred to as temporary in that adhesive can be disengaged and lining unit 42 can be removed without causing damage to the impermeable layer 44, by applying sufficient pulling force on lining unit 42. In this fashion, topmost lining unit 42u adheres to a top surface of lining unit 42c positioned thereunder. Lining unit 42c adheres to lining unit 42b, and this continues all the way until bottommost lining unit 42a which adheres directly to body liquid receptacle 22 or support 40. Each of the lining units 42 can be individually removed by disengaging its corresponding temporary adhesive. In some embodiments, a removable protective film can be provided on the top side of impermeable layer 44 to cover and protect absorbent material 46. In such embodiments, the adhesive can be provided on a top side of the protective film, or aligned with the protective film on the bottom side of a lining unit 42 superimposed thereon. In this fashion, topmost lining unit 42u can adhere to lining unit 42c via the protective film. When topmost lining unit 42u is removed, the protective film is removed therewith, exposing the absorbent material 46. Subsequent adjacent layers of lining units 42 can be configured in a similar fashion.

(33) In some embodiments, bottommost lining unit 42a can be permanently attached to receptacle 22 or support 40. The attachment is said to be permanent in that the adhesive or other attachment mechanism securing bottommost lining unit 42a is strong enough such that lining unit 42a cannot be removed without damaging impermeable layer 44. In some embodiments, an attachment mechanism can be provided on the engagement support 40 or on the receptacle 22 for securing the bottommost lining unit 42a.

(34) In the embodiment shown in FIG. 3, each one of the liquid lining units 42 includes a front removal tab 58a and a rear removal tab 58b extending outwardly from a periphery thereof. The purpose of which will be described in more detail below. It is appreciated that, in an alternative embodiment, the lining units 42 can be free of removal tabs, can include more removal tabs, such as a lateral tab, or can include only one removal tab, such as either the front removal tab, the rear removal tab or the lateral one. As will be described in more details below, one or more of the removal tabs 58a, 58b can have adhesive properties.

(35) As mentioned above, each one of the lining units 42a, 42b, 42c, 42u also includes the absorbent material layer 46. The absorbent material layer 46 is superposed to an upper surface of the respective one of lining units 42, for example on the liquid impermeable covers 44. Thus, in the embodiment shown, the multi-liner assembly 24 includes four lining units 42a, 42b, 42c, 42u wherein 42u is the uppermost one of the lining units, and 42a is a bottommost one of the lining units. When the multi-liner assembly 24 is mounted to the receptacle engagement support 40 (and optionally when the support 40 is engaged with the body liquid receptacle), the topmost lining unit 42u is exposed, whereas subsequent lining units 42a-42c are covered by the topmost lining unit 42u. More particularly, the absorbent material layer 46 of the uppermost lining unit 42u is exposed in the cavity 26 and visible from outside, and is thus positioned to receive body liquid in the cavity 26, as shown in FIG. 1. The impermeable cover 44 of topmost lining unit 42u prevents body liquid in the cavity 26 from contaminating subsequent lining units 42a-42c and the body liquid receptacle 22 itself.

(36) It is appreciated that the number and the shape of the lining units 42 of the multi-layer assembly 24 can vary from the embodiment shown. The multi-layer assembly 24 can have two or more superposed lining units 42.

(37) The uppermost lining unit 42u is detachable and removable from the remaining ones of the lining units 42 of the multi-liner assembly 24. Once the uppermost lining unit 42 is detached and removed, the lining unit 42c extending below and adjacent to the uppermost lining unit 42u before detachment and removal becomes the uppermost lining unit of the multi-liner assembly 24 with its absorbent material layer 46 being exposed. The new uppermost lining unit 42u is now detachable and removable from the remaining ones of the lining units 42 of the multi-liner assembly 24.

(38) The absorbent material layer 46 can be secured to its respective liquid impermeable cover 44 or can be provided separately and removable from the liquid impermeable cover 44.

(39) The absorbent material layer 46 is designed to capture liquids and can comprise, for example, a polymer or gel. The absorbent material layer substantially instantaneously holds liquids to ease handling. For example, it can include a superabsorbent polymer, i.e. a polymer that can absorb and retain extremely large amounts of a liquid relative to its own mass. As mentioned above, the absorbent material layer 46 can be a distinct component from the liquid impermeable cover 44 or it can be provided as a single-piece. For example, the gelling agent can be in powder crystal or fiber form, spread out over or stuck to the upper surface of each one of the liquid impermeable covers 44. It can be contained in a sachet which is placed or affixed to the upper surface of each one of the liquid impermeable covers 44. For example, it can be glued. The sachet can be made of a water soluble material or made of a material that is made fragile by the liquid so that it breaks upon contact with it (e.g. paper or cellulose wadding). Alternatively, in the embodiment shown in FIG. 5, the gelling agent particles (not shown) can be inserted into a non-woven material layer 62, such as and without being limitative cellulose pulp fluff, and covered with a top sheet 64, such as and without being limitative a non-woven cellulosic-fiber based tissue sheet. The top sheet 64 is liquid permeable. In an alternative embodiment, the non-woven material layer 62 including the gelling agent particles can be sandwiched between two sheets. In the embodiment shown in FIG. 5, the liquid impermeable cover 44 is used as an impermeable back sheet. The top sheet 64 can cover an entire surface of the liquid impermeable cover 44, or only a portion thereof, with the absorbent material layer 46 being sandwiched inbetween. In an embodiment, the absorbent material layer 46 has a smaller surface area than the liquid impermeable cover 44 and the top sheet 64, if any. In an embodiment, the elastic band 56 and/or drawstring 57 can be sandwiched between the liquid impermeable cover 44 and the top sheet 64, as shown in FIG. 5.

(40) Additional products can be added to the absorbent material layer 46 to improve comfort conditions. For example, it can include deodorants, antiseptics, virucides, antiretroviral, microbicides, bactericides, fungicides, or reagents, etc.

(41) Turning now to FIG. 6, there is shown that, when used, the multi-liner assembly 24 is engaged with the body liquid receptacle 22. In the embodiment shown, the multi-liner assembly 24 is engaged with the body liquid receptacle 22 by superposing the receptacle engagement support 40 to the body liquid receptacle 22 with aligned cavities 26, 53. When the multi-liner assembly 24 is engaged with the body liquid receptacle 22, the absorbent material layer 46 of the uppermost lining unit 42u is exposed in the cavity 26 and the liquid impermeable cover 44 of the uppermost lining unit 42u covers the cavity 26. In the embodiment shown, the seat member 34 is covered by the liquid impermeable cover 44 of the uppermost lining unit 42u with the elastic band 56 extending under the rim section 52 of the receptacle engagement support 40.

(42) When body liquid is received in the cavity 26, the absorbent material layer 46 of the uppermost lining unit 42u absorbs the body liquid and jellifies same. The uppermost lining unit 42u can then be individually removed from the multi-liner assembly 24 to leave a subsequent one of the lining units 42 exposed. Preferably, the removal tabs 58 of lining units 42 and/or the openings exposing drawstring 57 are positioned such that the tabs 58 and/or drawstrings 57 of the uppermost lining unit 42u are visible and accessible when the multi-layer assembly 24 is engaged with the body liquid receptacle 22. For example, the tab 58 and/or drawstring 57 opening can be positioned on an interior of lining unit 42u, so that when peripheral region of lining unit 42u is folded back over rim 52, tab 58 and/or drawstring 57 is visible on an exterior side of the receptacle 22, for example on or under rim 52. Alternatively, elastic band 56 can extend at least partially in a peripheral region inward relative to the tabs 58, allowing tabs to hang freely on the exterior of the receptacle 22 when the elastic band 56 is engaged with the receptacle 22 and/or support 40. In this fashion, uppermost lining unit 42u can be detached from the other ones of the lining unit 42a, 42b, 42c by pulling one or more of the removal tabs 58a, 58b and/or by pulling drawstring 57 to stretch the elastic band 56 and pull the liquid impermeable cover 44 of the uppermost lining unit 42u above the seat member 34. Once detached from the remaining lining units of the multi-layer assembly 24, the detached lining unit 42u is a pouch with an open mouth defined by the elastic band 56 and/or drawstring 57 as shown in FIG. 6. The absorbent material layer 46 is contained in the bottom of the pouch with any free liquid. The resilient properties of the elastic band 56 in the peripheral region of the lining unit 42 and/or pulling the drawstring 57 closes the open mouth of the pouch to reduce body liquid spillage, as shown by the arrows in FIG. 6.

(43) The lining units 42, detached and removed, can then be closed using a closure mechanism to prevent access to the absorbent material layer 46 and disposed. For example, the closure mechanism can comprise an adhesive on a first end 59a and/or second end 59b of the lining unit 42, for example on at least one of the removal tabs 58a, 58b. The adhesive can be used to close the removal tabs 58a, 58b as shown in FIG. 7. For instance, the peripheral region of lining unit 42 can be folded closed, and the tab with the adhesive on one side can be folded over and adhered to the opposite side of lining unit 42 to secure the sides together and close the lining unit. In some embodiments, for example if the liquid impermeable cover 44 includes two removal tabs 58a, 58b, the liquid impermeable cover 44 can be closed by superposing the two removal tabs 58a, 58b and applying a slight pressure thereon, as shown in FIG. 7. In some embodiments, for example when the closure mechanism includes a drawstring 57, the drawstring 57 can be pulled to completely close off a top portion of the lining unit 42, as shown in FIG. 8C. The top portion can further be tied in a knot to prevent body liquid contained therein from escaping, as shown in FIG. 8D.

(44) As shown in FIG. 6, when the uppermost lining unit is removed, the lining unit 42c extending below and adjacent to the uppermost lining unit 42u before detachment and removal becomes the uppermost lining unit of the multi-liner assembly 24 engaged with the body liquid receptacle 22 with its absorbent material layer 46 being exposed. The body liquid receptacle 22 can be used again without requiring to be cleaned or insertion and engagement of another lining assembly. The similar steps can be carried out until the multi-liner assembly 24 is empty of lining unit 42.

(45) It is appreciated that, in an alternative embodiment, the multi-liner assembly 24 can be free of receptacle engagement support 40 and that the superposed lining units 42 can be engaged directly with the body liquid receptacle 22. A lowermost one of the superposed lining units 42 can include an adhesive, such as a peelable adhesive, which can be activated when engaged with the body liquid receptacle 22, as described above. In some embodiments, also as described above, each of the lining units 42 in the multi-liner assembly 24 can be temporarily adhered to one another. The bottommost lining unit 42a can then be permanently or temporarily attached to the body liquid receptacle 22 directly. In some embodiments, each lining unit 42 can have its peripheral section wrapped directly around rim section 36 of receptacle 22. More lining units 42 can be added afterwards to provide more removable layers as necessary.
