Abstract

Abstract A compressible feeding apparatus for dispensing liquids, semi-solid foodstuffs or other edible or medicinal materials for feeding or administering to an infant, invalid or other person requiring assistance in such matters. The compressible feeding apparatus includes a feeding apparatus which includes a compressible receptacle, a nozzle assembly removably mounted on the receptacle and a utensil assembly slideably mounted on the nozzle assembly. The nozzle assembly includes as interior channel in communication with the interior of the receptacle and the utensil assembly includes an interior passage in communication with the interior channel. The sidewalls of the interior passage of the utensil assembly are configured to form, in combination with the nozzle assembly, a closeable valve for the feeder apparatus.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 332 words
A compressible feeding apparatus comprising: an axially compressible receptacle having an interior opening for storing liquid, semi-solid foodstuffs or other edible or medicinal materials therein, said receptacle having an open end in communication with said interior opening, a projecting neck section at said open end and a bottom section; a nozzle assembly removably mounted on said receptacle to cover said open end, said nozzle assembly having a nozzle section having an exterior surface, an interior channel in communication with said open end and said exterior surface for passage of said materials therethrough and a lid section for mating with said receptacle, said lid section comprised of a raised section which circumferentially surrounds said nozzle section, a generally flat section for grasping said compressible feeding apparatus during axial compression of said receptacle, said axial compression actuated by pressure exerted on said bottom section, and a circumferential sidewall integrally formed with the outer periphery of said flat section, said circumferential sidewall mating with said projecting neck section of said compressible receptacle; and a utensil assembly having an exterior surface, said utensil assembly mounted on said nozzle assembly and displaceable between first and second positions, said utensil assembly having an interior passage defined by an interior sidewall for the delivery of said material therefrom, said utensil assembly having a widened section circumferentially extending around said exterior surface of said utensil assembly, said widened section providing for ready grasping when movement of said utensil assembly between said first and second positions is desired and a circumferential end wall; wherein, in said first position, said interior channel and interior passage are in communication with each other and, in said second position, said interior channel is blocked from communication with said interior passage by the mating of said interior sidewall of said utensil assembly and said exterior surface of said nozzle assembly, said utensil assembly end wall and said raised section of said lid section circumferentially engaging along their widths when said apparatus is in said second position.
Claim 2
Dependent Claim 332 words
A compressible feeding apparatus comprising: an axially compressible receptacle having an interior opening for storing liquid, semi-solid foodstuffs or other edible or medicinal materials therein, said receptacle having an open end in communication with said interior opening, a projecting neck section at said open end and a bottom section; a nozzle assembly removably mounted on said receptacle to cover said open end, said nozzle assembly having a nozzle section having an exterior surface, an interior channel in communication with said open end and said exterior surface for passage of said materials therethrough and a lid section for mating with said receptacle, said lid section comprised of a raised section which circumferentially surrounds said nozzle section, a generally flat section for grasping said compressible feeding apparatus during axial compression of said receptacle, said axial compression actuated by pressure exerted on said bottom section, and a circumferential sidewall integrally formed with the outer periphery of said flat section, said circumferential sidewall mating with said projecting neck section of said compressible receptacle; and a utensil assembly having an exterior surface, said utensil assembly mounted on said nozzle assembly and displaceable between first and second positions, said utensil assembly having an interior passage defined by an interior sidewall for the delivery of said material therefrom, said utensil assembly having a widened section circumferentially extending around said exterior surface of said utensil assembly, said widened section providing for ready grasping when movement of said utensil assembly between said first and second positions is desired and a circumferential end wall; wherein, in said first position, said interior channel and interior passage are in communication with each other and, in said second position, said interior channel is blocked from communication with said interior passage by the mating of said interior sidewall of said utensil assembly and said exterior surface of said nozzle assembly, said utensil assembly end wall and said raised section of said lid section circumferentially engaging along their widths when said apparatus is in said second position.
Claim 3
Dependent Claim 37 words
A compressible feeding apparatus as set forth in claim 1 wherein said interior passage includes a first, narrower section from which said material is delivered, and a second, wider section which slideably mates with said nozzle assembly.
Claim 4
Dependent Claim 48 words
A compressible feeding apparatus as set forth in claim 2 wherein said nozzle assembly further comprises a conically shaped nozzle end which terminates in a generally flat tip, said nozzle end having annular apertures along the conical sides thereof, said annular apertures in communication with said interior channel.
Claim 5
Dependent Claim 52 words
A compressible feeding apparatus as set forth in claim 3 wherein said wider section of said interior sidewall of said utensil assembly is conically shaped to complement said conically shaped nozzle end, said complementary interior sidewall mating with said conically shaped nozzle end when said utensil assembly is in said second position.
Claim 6
Dependent Claim 42 words
A compressible feeding apparatus as set forth in claim 4 wherein said generally flat tip of said nozzle assembly is received in said interior passage when said utensil assembly is in said second position, said nozzle assembly tip, thereby blocking interior passage.
Claim 7
Dependent Claim 35 words
A compressible feeding apparatus as set forth in claim 5 wherein said compressible receptacle further comprises a plurality of axially protruding bellows with circumferential ribs positioned therebetween, said bellows being compressible at said circumferential ribs.
Claim 8
Dependent Claim 26 words
A compressible feeding apparatus as set forth in claim 6 wherein said bottom section inwardly protrudes to provide improved grasping of said receptacle during axial compression.
Claim 9
Dependent Claim 38 words
A compressible feeding apparatus according to claim 1 wherein said projecting neck section further comprises a threaded protrusion and wherein the interior of said lid sidewall further comprises a protrusion for threaded engagement with said projecting neck section.
Claim 10
Dependent Claim 80 words
A compressible feeding apparatus according to claim 1 wherein said nozzle assembly further comprises a circumferential rib for limiting the travel of said slideably mounted utensil assembly and wherein said interior sidewall of said utensil assembly further comprises an inner circumferential rib for engaging said circumferential rib of said nozzle assembly to limit the travel of said slideably mounted utensil assembly, the ribs of said nozzle and utensil assemblies engaging when said compressible feeding apparatus is in said first position.
Claim 11
Dependent Claim 54 words
A compressible feeding apparatus according to claim 9 and further comprising a cap threadably mountable on said sidewall of said lid section of said nozzle assembly when said apparatus is in said second position, thereby covering said nozzle and utensil assemblies and preventing movement of said utensil assembly between said first and second positions.
