Abstract
Abstract A tetrahedral or similarly shaped container is provided with a pair of tabs at one end. By pulling apart the tabs, an opening is formed at the one end. The end seal at the tab end of the container is shaped and positioned so as to provide for the combination of ease of opening, strong seal which will not distort the configuration of the container. The spout or seal opening region of the seal lies essentially in one longitudinal half of the container, inorder to provide a seal opening structure which utilizes a minimum amount of container material, while providing reasonably large tabs. Preferably, the seal opening is proximate one side of the container, so as to provide a pour spout, particularly in repeated use containers.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
91 words
A hollow container comprising: a cylindrical body portion having a pair of transversely sealed ends, each of said ends of said cylindrical body portion lying substantially in a plane, the plane of one of the ends of said cylindrical body potion being at approximately a right angle to the plane of the other end of said cylindrical body, one of said sealed ends having tab sections extending beyond the end seal, said seal deviating from a straight line in a region which lies essntially in one longitudinal half of the container.
Claim 2
Dependent Claim
91 words
A hollow container comprising: a cylindrical body portion having a pair of transversely sealed ends, each of said ends of said cylindrical body portion lying substantially in a plane, the plane of one of the ends of said cylindrical body potion being at approximately a right angle to the plane of the other end of said cylindrical body, one of said sealed ends having tab sections extending beyond the end seal, said seal deviating from a straight line in a region which lies essntially in one longitudinal half of the container.
Claim 3
Dependent Claim
98 words
A hollow container having a cylindrical body portion and a pair of sealed ends, each of said end seals being transverse to the longitudinal axis of said container and substantially offset with respect to the plane of the other of said seals, thereby causing said cylindrical body portion to be non-circular in cross-section, one of said seals having at least a region which deviates from a straight line, said region being proximate a side of the container, and a tab region, said tab region being unsealed free ends of said container adjacent to said one of said seals.
Claim 4
Dependent Claim
98 words
A hollow container having a cylindrical body portion and a pair of sealed ends, each of said end seals being transverse to the longitudinal axis of said container and substantially offset with respect to the plane of the other of said seals, thereby causing said cylindrical body portion to be non-circular in cross-section, one of said seals having at least a region which deviates from a straight line, said region being proximate a side of the container, and a tab region, said tab region being unsealed free ends of said container adjacent to said one of said seals.
Claim 5
Dependent Claim
17 words
The structure of claim 2, wherein said cylindrical body portion is in the form of a teterahedron.
Claim 6
Dependent Claim
18 words
The structure of claim 2, wherein the plane of said seals are at right angles to each other.
Claim 7
Dependent Claim
49 words
The structure of claim 1, further comprising a tab region, sad tab region being bounded on one side by said one of said seals and extending beyond said one of said seals, said region being sealed at its peripheral edges, and a drinking straw enclosed within said tab region.
Claim 8
Dependent Claim
23 words
The structure of claim 2, wherein said one of said seals has a pair of sealed sections which extend into the tab region.
Claim 9
Dependent Claim
105 words
A hollow container having a cylindrical body portion and a pair of sealed ends, each of said sealed ends having end seals transverse to the longitudinal axis of said container and lying substantially in a plane, the plane of one of said seals being substantially offset with respect to the plane of the other of said seals, thereby causing said cylindrical body portion to be non-circular in cross-section, a tab region, said tab region being formed by ends of said container which extend beyond one of said seals, and a drinking straw in said tab region, said tab region being sealed along its peripheral edges.
Claim 10
Dependent Claim
105 words
A hollow container having a cylindrical body portion and a pair of sealed ends, each of said sealed ends having end seals transverse to the longitudinal axis of said container and lying substantially in a plane, the plane of one of said seals being substantially offset with respect to the plane of the other of said seals, thereby causing said cylindrical body portion to be non-circular in cross-section, a tab region, said tab region being formed by ends of said container which extend beyond one of said seals, and a drinking straw in said tab region, said tab region being sealed along its peripheral edges.
Claim 11
Dependent Claim
16 words
The structure of claim 7, wherein said cylindrical body is in the form of a tetrahedron.
Claim 12
Dependent Claim
18 words
The structure of claim 7, wherein the planes of said seals are at right angles to each other.
Claim 13
Dependent Claim
23 words
The structure of claim 7, wherein said one of said seals has a pair of seal sections which extend into said tab region.
Claim 14
Dependent Claim
71 words
A hollow tube having a plurality of spaced seals, adjacent seals lying in non-parallel planes and each seal lying in a plane parallel to an alternate seal, thus forming a plurality of hollow containers, every other seal being a composite seal and including two mirror image seals having a region which deviates from a straight line, said region being essentially in one longitudinal half of said container which includes the region.
Claim 15
Dependent Claim
71 words
A hollow tube having a plurality of spaced seals, adjacent seals lying in non-parallel planes and each seal lying in a plane parallel to an alternate seal, thus forming a plurality of hollow containers, every other seal being a composite seal and including two mirror image seals having a region which deviates from a straight line, said region being essentially in one longitudinal half of said container which includes the region.
Claim 16
Dependent Claim
