Abstract
Abstract A container comprised of a top member having an opening for filling and pouring in the conventional manner and a bottom member integrally connected together by a flexible compressible or collapsible mid-section. Means are also provided for externally connecting between the top and bottom member of the container, which external means operate to alter and maintain the internal volume of the container. Progressive adjustments in internal volume are possible.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
151 words
A container for storing material therein and having an opening adapted for filling and pouring said material contents, said material including volatile components generating a gas pressure in the portion of said container not filled with said material, said internal pressure exceeding the external ambient pressure, comprising: a first portion, a second portion, and a third collapsible portion positioned between said first and second portions and joined thereto to form an enclosure for said stored material; adjustable means for incrementally collapsing said collapsible portion, the internal volume of said container being varied for each incremental adjustment, and for maintaining said container at each condition of adjusted internal volume, the volume of said container being subject to reduction incrementally for storage of said container after portions of said contents are discharged from said opening; and means for sealing said opening against the escape of said internal gas under pressure to said ambient.
Claim 2
Dependent Claim
151 words
A container for storing material therein and having an opening adapted for filling and pouring said material contents, said material including volatile components generating a gas pressure in the portion of said container not filled with said material, said internal pressure exceeding the external ambient pressure, comprising: a first portion, a second portion, and a third collapsible portion positioned between said first and second portions and joined thereto to form an enclosure for said stored material; adjustable means for incrementally collapsing said collapsible portion, the internal volume of said container being varied for each incremental adjustment, and for maintaining said container at each condition of adjusted internal volume, the volume of said container being subject to reduction incrementally for storage of said container after portions of said contents are discharged from said opening; and means for sealing said opening against the escape of said internal gas under pressure to said ambient.
Claim 3
Dependent Claim
23 words
A container as claimed in claim 1, wherein said internal volume is reduced by reducing the distance between said first and second portions.
Claim 4
Dependent Claim
73 words
A container as claimed in claim 2, wherein said adjustable means includes at least two threaded elements, a first said threaded element being connected to said first container portion, a second said threaded element being connected to said second container portion, said at least two threaded elements being threadably engaged, said distance between said first and second portions being adjustable by varying the amount of engagement of said at least two threaded elements.
Claim 5
Dependent Claim
62 words
A container as claimed in claim 3, wherein said first threaded element at least in part encloses therein said first portion of said container, and said second threaded element at least in part encloses said second container portion, the combination of said at least two threaded elements, when threadably engaged, enclosing at least in part said third collapsible portion of said container.
Claim 6
Dependent Claim
47 words
A container as claimed in claim 3, wherein said first container portion is cylindrical and said first threaded element is formed on the surface of said cylinder, said second threaded element being one of a threaded nut and a threaded shell rotatably engaging said first threaded element.
Claim 7
Dependent Claim
63 words
A container as claimed in claim 2, wherein said adjustable means includes at least a tooth on a side surface of said first container portion, and a nut connected to said second container portion, said nut having at least one pawl extending therefrom, one end of said at least one pawl being adapted to selectively and releasably engage said at least one tooth.
Claim 8
Dependent Claim
74 words
A container as claimed in claim 6, wherein the number of said teeth is at least two, said teeth being spaced apart longitudinally in the direction of adjusting said distance between said first and second container portions, said one end of said at least one pawl being adapted to releasably engage successive teeth in said longitudinal direction as said distance is reduced, whereby said container is maintainable at a plurality of different internal volumes.
Claim 9
Dependent Claim
62 words
A container as claimed in claim 7, wherein said first container portion and said nut are circular, said nut being rotatably connected to said second portion, said teeth being discontinuous around the circumference of said first container portion, rotation of said nut causing said pawl to disengage from said teeth, said disengaged pawl being slidable in said lengthwise direction without tooth engagement.
Claim 10
Dependent Claim
76 words
A container as claimed in claim 2, wherein said adjustable means includes at least two telescoping elements, a first said telescoping element being connected to said first container portion, a second said telescoping element being connected to said second container portion, and means for connecting together said telescoping elements with varying amounts of overlap of said telescoping elements, said container internal volume being decreased as the amount of said overlap of said telescoping elements is increased.
Claim 11
Dependent Claim
37 words
A container as claimed in claim 9, wherein said means for connecting together said telescoping elements includes holes in said telescoping elements, and pegs removably fitted simultaneously into aligned holes in at least two said telescoping elements.
Claim 12
Dependent Claim
60 words
A container as claimed in claim 9 or 10, wherein said first telescoping element at least in part encloses therein said first container portion and said second telescoping element at least in part encloses said second container portion, the combination of said at least two telescoping elements, when connected together, enclosing at least in part said third collapsible container portion.
Claim 13
Dependent Claim
85 words
A container as claimed in claim 2, wherein said adjustable means includes a first offset element connected to said first container portion, and a second offset element connected to said second container portion, a third offset element connected between said first and second offset element, means for selectively setting the length of said third offset element between said first and second offset elements, and for releasably holding said selected length, said distance between said first and second container portions being related to said selected length.
Claim 14
Dependent Claim
69 words
A container as claimed in claim 12, wherein said third offset element is cylindrical, and said setting and holding means includes a threaded member on one of said first and second offset elements, said cylindrical element passing slidably through said threaded member, and a nut mating with said threaded member, tightening said nut to said threaded member releasably holding the setting of said cylindrical element in said threaded member.
Claim 15
Dependent Claim
68 words
A container as claimed in claim 12, wherein said third offset element is a wavy member, one of said first and second offset elements including a portion for releasably engaging said wavy member, said engagement portion being resilient, said wavy member being movable through said resilient portion, the resilience of said portion releasably holding said wavy member at any selected position along the length of said wavy member.
Claim 16
Dependent Claim
67 words
A container as claimed in claim 2, and further comprising gripper means connected to said first and to said second container portions, and flexible means extending between said gripper means on said first and second container portions, the length of said flexible means being variable, reducing the length of said flexible means extended between said first and second container portions reducing the internal volume of said container.
