DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0030] An autonomous feeding system 10 according to an embodiment is depicted generally in FIG. 1. Although autonomous feeding system 10 can be used for any number of purposes, the illustrated embodiment is especially adapted for delivering liquid or semi-liquid (alternately referred to as semi-solid) nutrition to a user. Autonomous feeding system 10 may be particularly useful in facilitating autonomous feeding (i.e., feeding oneself) by a young child from a receptacle containing pured baby food.

[0031] Referring to FIGS. 1-2, autonomous feeding system 10 generally includes adapter 20 and conduit 60. In embodiments, autonomous feeding system 10 may also include a receptacle 70, such as the jar depicted in FIGS. 10-11. It will be easily recognized that the receptacle 70 can be a common baby food jar, or other well-known container that typically contains liquid or semi-liquid food.

[0032] As shown in FIGS. 1-4, adapter 20 generally includes extension 22, cover portion 24, outer sidewalls 26, inner sidewalls 28 and projection 30. Adapter 20 may also include transition area 32 between extension 22 and cover portion 24, as well as lip 34. Outer sidewalls 26 may include ridges 35 adapted to facilitate gripping of outer sidewalls 26 by a user. As outlined below in further detail, adapter 20 is specifically configured to be coupled with the receptacle 70, thus providing the ability for a young child to feed themselves.

[0033] Outer sidewalls 26 extend circumferentially about cover portion 24. Inner sidewalls 28 are spaced apart from outer sidewalls 26 such that inner sidewalls 28 and outer sidewalls 26 form gap 36. Outer sidewalls 26 and inner sidewalls 28 extend generally away from extension 22. Gap 36 is generally configured to conformingly receive receptacle 70 so as to form a substantially liquid-impermeable compression fit, or seal, about a rim portion of the receptacle.

[0034] As shown in FIGS. 1-7, cover portion 24, outer sidewalls 26 and inner sidewalls 28 are adapted to a receive a receptacle having a substantially circular opening, such as the receptacles shown and described in USD289259, USD298592, USD516429 and USD754544. In alternative embodiments, cover portion 24, outer sidewalls 26 and inner sidewalls 28 are configured to receive a receptacle defining a non-circular opening, such as a baby food container defining a substantially rectangular opening.

[0035] Extension 22 includes elongated portion 38 having a proximal end 40 and distal end 42. Extension 22 defines extension channel 43 and may also include ribbing 44 extending between proximal end 40 and distal end 42. As depicted in FIGS. 1-4, proximal end 40 terminates in transition area 32. Alternatively, proximal end 40 may terminate in cover portion 24 without the presence of transition area 32. Distal end 42 of extension 22 defines opening 46. Opening 46 may be configured in any number of ways. As depicted in FIG. 8, for example, distal end 42 of extension includes a plurality of flaps 48 arranged so as to define opening 46 in a cross, or +, shape. In an alternative embodiment, distal end 42 may define a single slit such that deformation of distal end 42 produces opening 46. In yet another embodiment, distal end 42 defines an unobstructed aperture. A feature and advantage of the present system is the ability to modify the size and/or shape of opening 46 so as to control the flow rate of non-solid materials, such as pured baby food, through extension channel 43.

[0036] Projection 30 generally extends away from extension 22 in a direction that is substantially parallel with outer sidewalls 26 and inner sidewalls 28. As shown in FIGS. 1-4, projection 30 extends slightly beyond the plane defined by lip 34. In alternative embodiments, projection 30 may extend before or substantially coextensive with the plane defined by lip 34. Projection 30 also defines projection channel 50 adapted to receive conduit 60. Projection channel 50 is in fluid communication with channel 43 of elongated portion 38 of extension 22. As shown in FIGS. 2 and 4, extending between and in fluid communication with projection channel 50 and extension channel 43 is transition area channel 52. Transition area channel 52 may be chamfered to facilitate the formation of a compression fit about conduit 60. The location in transition area channel 52 or projection channel 50 at which conduit 60 occupies a resting position is referred to herein as the conduit stop. Referring to FIG. 2, conduit stop 27 is shown as the location where projection 26 meets transition area 32.

[0037] Conduit 60 is a generally tubular member 62 having first end 64 and a second end 66. Conduit 60 defines conduit channel 68 extending between the first and second ends 64, 66. Although FIGS. 1 and 9-11 depict conduit 60 as a generally linear structure, conduit 60 may be non-linear as well. First end 64 of conduit 60 is adapted to be received by projection channel 50 such that projection 50 forms a seal around first end 64 of conduit. Therefore, the diameter of conduit 60 will generally be minimally larger that the diameter of projection channel 50. Second end 66 of conduit 60 may have the same of different dimensions as first end 64 of conduit. In an embodiment, second end 64 is canted with respect to tubular member. Although the diameters of conduit channel 68 and extension channel 43 can be different, they are generally substantially similar or the same to facilitate cleaning of the conduit channel 68 and extension channel 43 with a single cleaning device, such as a tube brush.

[0038] The length of conduit 60 can be varied in accordance with user preference. Additionally, various conduits 60 of different length may be provided such that a user can select the optimum length for a given receptacle 70. Referring to FIG. 4, a type of receptacle 70, such as glass baby food jar, has sidewalls 72 and bottom surface 74. Bottom surface 74 is concave such that bottom surface 74 has apex 76 and defines circumferential furrow 78 where sidewalls 72 meet bottom surface 74. In an embodiment, tubular member 62 has a length that is substantially equal to the distance between furrow 78 and stop 27.

[0039] The dimensions of the various features and components of autonomous feeding system 10 can be varied to conform to them to the sizes and shapes of different types of receptacles 70. In the embodiment depicted in FIGS. 3b and 4b, autonomous feeding system 10 is adapted to 4 oz. or 6 oz. baby food jars manufactured by Gerber, Beech-Nut and/or Earth's Best Organic.

[0040] Adapter 20 is preferably made from a resilient polymer, although other materials could be used. In an embodiment, the heretofore described components of adapter 20 are integrally formed from a silicone polymer. In an alternative embodiment, outer sidewalls 26 of adapter 20 are made from a rigid material, such as plastic or metal, and may include complementary threads such that adapter 20 can be screwed onto the threaded rim portion of receptacle 70. Conduit 60 is generally made from a polymer characterized by a greater degree of stiffness. In an embodiment, conduit 60 is made from BPA-free plastic. One skilled in the art will readily recognize, however, that adapter 20 and conduit 60 can be made from any number of materials without departing from the spirit or scope of the present invention.

[0041] Autonomous feeding system 10 can be used for any number of purposes; however, autonomous feeding system 10 is particularly adapted to provide facilitate utensil-free extraction of semi-solid or pured food from a jar. In this manner, a young child can feed himself or herself by simply sucking on a straw-like flexible tube rather than requiring the assistance of a parent or other caregiver in being fed by a spoon.

[0042] A method according to an embodiment of the present invention includes inserting conduit 60 into projection 30 and subsequently fitting cover portion 24 of adapter 20 about the rim of receptacle 70. Since adapter 20 is generally made from a substantially resilient material, cover portion 24 can be stretch-fit about and forms a seal around the rim of receptacle 70. As previously described, outer sidewalls 26 may alternatively be made from a rigid material and include interior-facing threads such that adapter 20 can be screwed onto receptacle 70. Embodiments in which outer sidewalls 26 are threaded typically will not include inner sidewalls 28.

[0043] As adapter 20 is fitted about receptacle 70, the concave shape of bottom surface 74 of receptacle 70 naturally urges second end 66 of conduit 60 toward furrow 78, as shown in FIG. 10. In embodiments, the inherent elasticity of cover portion 24 provides assistance in retaining of second end 66 of conduit 60 within furrow 78. With conduit 60 positioned in furrow 78, receptacle 70 can be oriented by a user so as to maximize the quantity of food that can be accessed by a user with autonomous feeding system 10.

[0044] Since adapter 20 is substantially sealed about receptacle 70 and conduit 60 is substantially sealed within projection 30 while channel 43 of extension 22 remains in fluid communication with conduit channel 68, a user can create negative pressure by sucking on distal end 42 of extension 22. This negative pressure causes a liquid or pured (or other semi-solid) food to be drawn from receptacle 70, through conduit channel 68 and extension channel 43, and exit through opening 46 in distal end 42 of extension 22. When the user is done sucking on extension 22 and the pressure is equalized, the small size of opening 46 substantially prevents the liquid or pured food from leaking through opening 46 even if receptacle 70 is tipped sideways or upside-down.

[0045] Various embodiments of the invention have been described above for purposes of illustrating the details thereof and to enable one of ordinary skill in the art to make and use the invention. The details and features of the disclosed embodiment or embodiments are not intended to be limiting, as many variations and modifications will be readily apparent to those of skill in the art. Accordingly, the scope of the present disclosure is intended to be interpreted broadly and to include all variations and modifications coming within the scope and spirit of the appended claims and their legal equivalents.
