Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
203 words
A two-piece nestable cup-like container comprising, in combination: a sidewall formed from a single double-ended sheet of a heat-shrinkable thermoplastic material, and having an inner surface adapted to contact a liquid product to be contained in said container, the ends of said sheet being joined to one another to form a liquid-tight seam extending from the top to the bottom of said container, said container having a mouth at its top which is defined by the upper portion of the sidewall, said upper portion being reversely folded into a relatively thin tight bead which surRounds said mouth, said sidewall continuously and progressively tapering inwardly and downwardly from a point near the open mouth of the container to a point near the bottom of the container for a major portion of the height of the container, the height of said major portion constituting substantially more than one-half of the height of said container, the thickness of the sidewall increasing continuously and progressively over said major portion from a lesser thickness at the top to a greater thickness at the bottom thereof; and a piece separate from the unitary sidewall and sealingly joined thereto for closing the bottom of the container in a liquid-tight manner.
Claim 2
Dependent Claim
203 words
A two-piece nestable cup-like container comprising, in combination: a sidewall formed from a single double-ended sheet of a heat-shrinkable thermoplastic material, and having an inner surface adapted to contact a liquid product to be contained in said container, the ends of said sheet being joined to one another to form a liquid-tight seam extending from the top to the bottom of said container, said container having a mouth at its top which is defined by the upper portion of the sidewall, said upper portion being reversely folded into a relatively thin tight bead which surRounds said mouth, said sidewall continuously and progressively tapering inwardly and downwardly from a point near the open mouth of the container to a point near the bottom of the container for a major portion of the height of the container, the height of said major portion constituting substantially more than one-half of the height of said container, the thickness of the sidewall increasing continuously and progressively over said major portion from a lesser thickness at the top to a greater thickness at the bottom thereof; and a piece separate from the unitary sidewall and sealingly joined thereto for closing the bottom of the container in a liquid-tight manner.
Claim 3
Dependent Claim
17 words
A container according to claim 1 where said heat-shrinkable thermoplastic material is an expanded, heat-shrinkable thermoplastic material.
Claim 4
Dependent Claim
29 words
A container according to claim 2 wherein said expanded heat-shrinkable thermoplastic material comprises polystyrene of an average density of the order of 10 to 18 pounds per cubic foot.
Claim 5
Dependent Claim
33 words
A container in accordance with claim 3 wherein the thickness of the sidewall of such container, at an elevation proximate to the upper open end thereof, is of the order of 20-30 mils.
Claim 6
Dependent Claim
40 words
A container according to claim 2 wherein the taper of the major portion of the sidewall increases from a minimum taper at an upper, thinner region of said major portion to a greater taper at a lower, thicker region thereof.
Claim 7
Dependent Claim
40 words
A container according to claim 5 wherein said taper is of the order of 5*-7* at the upper region of the major portion of the sidewall and is of the order of at least 15* at the lower region thereof.
Claim 8
Dependent Claim
30 words
A container according to claim 5 wherein said taper increases progressively from said minimum taper to said greater taper along the distance from said upper region to said lower region.
Claim 9
Dependent Claim
59 words
A container according to claim 1 wherein the sidewall is provided with an inwardly extending shoulder at a location outside of said major portion against which a portion of a substantially identical container is adapted to abut when said substantially identical container is inserted into said container in nested relationship to maintain a predetermined minimum spacing between said containers.
Claim 10
Dependent Claim
43 words
A pair of substantially identical containers each of which is constructed in accordance with claim 8, one of said containers being inserted in the other in nested relationship with said portion of said container abutting against the said shoulder of the other container.
Claim 11
Dependent Claim
40 words
A container according to claim 8 wherein said inwardly extending shoulder is located in said sidewall at a location below said major portion, and wherein the portion of a substantially identical container is an annular portion of the bottom thereof.
Claim 12
Dependent Claim
47 words
A pair of substantially identical containers each of which is constructed in accordance with claim 10, one of said containers being inserted in the other in nested relationship with said annular portion of the bottom of said container abutting against the said shoulder of the other container.
Claim 13
Dependent Claim
43 words
A container according to claim 2 wherein the ends of the sheet of thermoplastic material are joined to one another in an overlapped relationship, and wherein the sidewall is of a reduced thickness and increased density in the region of the overlapping ends.
Claim 14
Dependent Claim
32 words
The combination comprising a container according to claim 1 and a liquid contained therein, said liquid being in face to face contact with the inner surface of the sidewall of the container.
Claim 15
Dependent Claim
25 words
The combination according to claim 13 wherein the heat-shrinkable thermoplastic material is an expanded, heat-shrinkable thermoplastic material and wherein the liquid is a hot beverage.
Claim 16
Dependent Claim
23 words
A container according to claim 1 wherein said unitary sidewall is formed from a sheet of rectangular configuration of said heat-shrinkable thermoplastic material.
Claim 17
Dependent Claim
20 words
A container according to claim 1 wherein the ends of said sheet are joined to one another by heat sealIng.
Claim 18
Dependent Claim
35 words
A two-piece container according to claim 1 wherein the sidewall has an annular, inturned, transversely extending portion and wherein the piece separate from the unitary sidewall is joined to said inturned portion by heat sealing.
Claim 19
Dependent Claim
31 words
A container according to claim 5 wherein the product of sidewall circumference and sidewall thickness is substantially constant at all elevations from said upper thinner region to said lower thicker region.
