Abstract

A container including a longitudinal overlapping seam extending from an end seam and a mold part line extending from the closed end of the container to the open end of the container. The container wall consists of a one-piece thermoplastic substrate.

First claim

What is claimed is:

1. A container comprising:
an open end;
a closed end opposing said open end;
a container wall extending longitudinally between said closed end and said open end about a longitudinal axis;
an end seam extending at least partially across said closed end;
a longitudinal overlapping seam extending from said end seam, a portion of said overlapping seam extending from said end seam and longitudinally along said container wall; and
a mold part line extending from said closed end to said open end;
wherein said open end is narrower than at least a portion of said container away from said open end of said container;
wherein said closed end and said container wall consist of a one-piece thermoplastic substrate;
wherein said container has a height extending between said closed end and said open end;
wherein said overlapping seam along said container wall has an overlap magnitude ( 430 ) at a location about 10% of the height away from said closed end; and
wherein at a location that is about 10% of the height away from said closed end said mold part line and said overlapping seam are within a distance of one another of less than about five times said overlap magnitude.

2. The container according to claim 1 , wherein said part line protrudes from said container wall.

3. The container according to claim 1 , wherein said container comprises an additional mold part line extending from said closed end to said open end.

4. The container according to claim 3 , wherein said mold part lines are on opposite sides of said container.

5. The container according to claim 1 , wherein said container further comprises a label spaced apart from said overlapping seam and said mold part line.

6. The container according to claim 5 , wherein said label comprises a label substrate and ink.

7. The container according to claim 6 , wherein said label is an in-mold label.

8. The container according to claim 6 , wherein said label is bonded to said container wall.

9. The container according to claim 6 , wherein said label is an adhesive label.

10. The container according to claim 1 ,
wherein said container wall extends around a longitudinal axis;
wherein at mid-height along said longitudinal axis said container has a local maximum internal dimension orthogonal to said longitudinal axis, a local major axis coincident with said local maximum internal dimension, a local minor axis orthogonal to said local major axis and said longitudinal axis, a local minor internal dimension coincident with said local minor axis, and a local aspect ratio defined as a ratio of said local maximum internal dimension to said local minor internal dimension, wherein said local aspect ratio is greater than about 1.

11. The container according to claim 10 , wherein said mold part line is nearer to where a front plane defined by said local major axis and said longitudinal axis intersects said container wall than where a sagittal plane defined by said local minor axis and said longitudinal axis intersects said container wall.

12. The container according to claim 11 , wherein said mold part line is substantially coincident with where said front plane intersects said container wall.

13. The container according to claim 10 , wherein said local aspect ratio is greater than 1.3.

14. The package according to claim 1 , wherein said thermoplastic substrate comprises a composition selected from the group consisting of polyethylene terephthalate, polystyrene, polypropylene, polyethylene, polyvinyl chloride, nylon, ethyl vinyl alcohol, and mixtures thereof.

15. The package according to claim 1 , wherein at a location that is about 10% of the height away from said closed end said container wall has a thickness away from said overlapping seam and said overlap magnitude is more than about 1.5 times said thickness of said container wall as measured at a distance from said overlapping seam equal to said overlap magnitude.

16. The package according to claim 1 , wherein said container wall has a thickness away from said overlapping seam, wherein said overlapping seam at a location that is about 10% of said height away from said closed end is thicker than any other portion of said container wall at a location that is about 10% of said height away from said closed end.
