Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
285 words
In a compressible drinking apparatus for holding a quantity of liquid and including a deformable liquid-containing bag having an open end, a hollow neck member for substantially fluid-tight sealing engagement with the open end of the liquid-containing bag so as to enable liquid in the bag to communicate with the hollow interior of said neck member and for completing with the bag a substantially closed container for holding a quantity of liquid, flexible straw means in the liquid-containing interior of the bag and communicating fluid-tightly through said neck member with the exterior of said closed container such that when an external deforming force is inwardly applied to the bag the liquid therein contained is forced through said straw means to the exterior of the container and dispensed from said straw means for drinking, and storage enabling means on the bag and including means cooperable with said neck member such that when the contained liquid has been dispensed from the bag through said straw means said drinking apparatus is compressible to a compact, unitary storage condition in which said storage enabling means is moved into holding cooperation with said neck member while the bag and flexible straw means are deformedly disposed in the hollow interior of said neck member and therein captured by the cooperative holding of the neck member and storage enabling means, said neck member including a filling opening defined therein remote from its engagement with the bag and communicating with the hollow interior of said neck member for enabling the addition of liquid to the bag through said neck member, and a sealing cap engageable with said neck member for fluid-tightly closing said filling opening when the bag contains a quantity of liquid.
Claim 2
Dependent Claim
285 words
In a compressible drinking apparatus for holding a quantity of liquid and including a deformable liquid-containing bag having an open end, a hollow neck member for substantially fluid-tight sealing engagement with the open end of the liquid-containing bag so as to enable liquid in the bag to communicate with the hollow interior of said neck member and for completing with the bag a substantially closed container for holding a quantity of liquid, flexible straw means in the liquid-containing interior of the bag and communicating fluid-tightly through said neck member with the exterior of said closed container such that when an external deforming force is inwardly applied to the bag the liquid therein contained is forced through said straw means to the exterior of the container and dispensed from said straw means for drinking, and storage enabling means on the bag and including means cooperable with said neck member such that when the contained liquid has been dispensed from the bag through said straw means said drinking apparatus is compressible to a compact, unitary storage condition in which said storage enabling means is moved into holding cooperation with said neck member while the bag and flexible straw means are deformedly disposed in the hollow interior of said neck member and therein captured by the cooperative holding of the neck member and storage enabling means, said neck member including a filling opening defined therein remote from its engagement with the bag and communicating with the hollow interior of said neck member for enabling the addition of liquid to the bag through said neck member, and a sealing cap engageable with said neck member for fluid-tightly closing said filling opening when the bag contains a quantity of liquid.
Claim 3
Dependent Claim
15 words
In a compressible drinking apparatus according to claim 1, said neck member being relatively rigid.
Claim 4
Dependent Claim
22 words
In a compressible drinking apparatus according to claim 1, means on said neck member for releasable cooperation with said storage enabling means.
Claim 5
Dependent Claim
19 words
In a compressible drinking apparatus according to claim 1, said storage enabling means being formed integral with the bag.
Claim 6
Dependent Claim
26 words
In a compressible drinking apparatus according to claim 1, said storage enabling means being carried on an end of the bag substantially opposite its open end.
Claim 7
Dependent Claim
203 words
A compressible drinking apparatus comprising a deformable bag having an opening through which liquid may be supplied to said bag, a hollow neck member having an opening through which liquid may be supplied to said bag, said bag and neck member being connected with each other to retain open said bag opening and to support said bag from said neck member, a cap releasably cooperable with said neck member for fluid tightly closing said bag opening to prevent the loss of liquid therefrom, storage means connected with said bag and cooperable with said neck member to store said bag within said neck member when liquid is dispensed from said bag to retain said bag in a compressed condition between said storage means and said neck member and being releasable from said cooperation with said neck member to enable said compressed beg to expand when a liquid is supplied thereinto, and straw means in said bag and extending outwardly therefrom to the exterior of said drinking apparatus to enable the withdrawal and dispensing of liquid from said bag, said straw means being deformable to be compactly compressed with and within said bag when said bag is compressed between said storage means and neck member.
Claim 8
Dependent Claim
203 words
A compressible drinking apparatus comprising a deformable bag having an opening through which liquid may be supplied to said bag, a hollow neck member having an opening through which liquid may be supplied to said bag, said bag and neck member being connected with each other to retain open said bag opening and to support said bag from said neck member, a cap releasably cooperable with said neck member for fluid tightly closing said bag opening to prevent the loss of liquid therefrom, storage means connected with said bag and cooperable with said neck member to store said bag within said neck member when liquid is dispensed from said bag to retain said bag in a compressed condition between said storage means and said neck member and being releasable from said cooperation with said neck member to enable said compressed beg to expand when a liquid is supplied thereinto, and straw means in said bag and extending outwardly therefrom to the exterior of said drinking apparatus to enable the withdrawal and dispensing of liquid from said bag, said straw means being deformable to be compactly compressed with and within said bag when said bag is compressed between said storage means and neck member.
Claim 9
Dependent Claim
30 words
A drinking apparatus as in claim 6, said straw means in said drinking apparatus extending outwardly therefrom through said neck member to enable the withdrawal of liquid from said bag.
Claim 10
Dependent Claim
33 words
A drinking apparatus as in claim 7, said connection between said bag and said neck member providing for a fluid tight connection therebetween and being releasable for exchange and replacement of said bags.
