Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
177 words
An apparatus for dispensing liquid comprising in combination, a first cylindrical container having an open top and a closed bottom, a second cylindrical container adapted to be snugly received in said first container so as to provide a liner therefor, said second container having a closed top provided with two spaced frangible sealing elements, a liquid conduit depending from one of said sealing means to a point adjacent the bottom of said second container and a closure means adapted to be sealingly secured over the top of said first container and having a plurality of depending rupture means adapted to be placed in registry with said frangible sealing means and when pressed downwardly on said sealing means, to rupture them, said rupture means comprising pointed tubular elements, one of which, after such rupture, will be placed in communication with the interior of said liquid conduit, while the other will be placed in communication with the top portion of said second container, to provide a passage for introducing gas under pressure to expel liquid from said second container.
Claim 2
Independent Claim
177 words
An apparatus for dispensing liquid comprising in combination, a first cylindrical container having an open top and a closed bottom, a second cylindrical container adapted to be snugly received in said first container so as to provide a liner therefor, said second container having a closed top provided with two spaced frangible sealing elements, a liquid conduit depending from one of said sealing means to a point adjacent the bottom of said second container and a closure means adapted to be sealingly secured over the top of said first container and having a plurality of depending rupture means adapted to be placed in registry with said frangible sealing means and when pressed downwardly on said sealing means, to rupture them, said rupture means comprising pointed tubular elements, one of which, after such rupture, will be placed in communication with the interior of said liquid conduit, while the other will be placed in communication with the top portion of said second container, to provide a passage for introducing gas under pressure to expel liquid from said second container.
Claim 3
Dependent Claim
31 words
Apparatus as in claim 1 wherein each of said sealing elements is provided with a central marking to facilitate proper positioning of said rupture means with respect to said sealing elements.
Claim 4
Dependent Claim
48 words
Apparatus as in claim 1 wherein said second container has a bottom closure which is outwardly concave and inwardly convex and said liquid conduit has an open lower end which is cut off on an incline so that it generally parallels the inner surface of said bottom closure.
Claim 5
Dependent Claim
82 words
Apparatus as in claim 3, further including a dish-shaped member fitted between the concave bottom surface of the second container and the bottom of the first container and having its convex outer surface fitting snugly within said concave bottom surface and a compression spring bearing against the bottom of said first container and the interior of said dish-shaped member for cushioning said second container in said first container and for permitting free rotational movement of said second container in said first container.
Claim 6
Dependent Claim
19 words
Apparatus as in claim 4 including means for firmly holding said closure means in position and said first container.
Claim 7
Dependent Claim
18 words
Apparatus as in claim 5 wherein said last-mentioned means comprises engaging screw threads on said closure and container.
Claim 8
Dependent Claim
41 words
Apparatus as in claim 6 wherein said sealing means comprise plugs of elastic material which are compressed and inserted into openings in the top wall of said second container, said openings being slightly smaller than the normal size of said plugs.
Claim 9
Dependent Claim
30 words
Apparatus as in claim 7 wherein said rupture means are provided above and adjacent their pointed ends with openings providing communication between the exterior and interior of said rupture means.
Claim 10
Dependent Claim
58 words
Apparatus as in claim 8 wherein the tops and side walls of said second container are crimped together to provide an annular ring and said closure means is provided with a downwardly opening groove which embraces said ring and the upper edge of the wall of the first container when said closure and containers are in assembled condition.
