Abstract

A container including a paperboard shell layer and a paperboard core layer. The container has a predetermined removable portion the provides for a separable cap portion. The body portion of the container extends from the shell bottom edge to a lower line of limitation. The body portion includes a lobe beneath the lower line of limitation defining the body. The lobe can be used to tightly fit the cap portion to the body portion after opening the container.

First claim

What is claimed is:

1. A container comprising:
a paperboard shell layer about a longitudinal axis and extending from a shell bottom edge to a shell top edge, wherein said shell layer comprises:
a body portion extending from said shell bottom edge to a lower line of limitation;
a predetermined removable portion extending from said lower line of limitation to an upper line of limitation; and
a cap portion extending from said upper line of limitation to said shell top edge; and
a paperboard core layer extending at least partially about said longitudinal axis and interior to said shell layer, wherein said core layer is joined to said body portion and extends from below said lower line of limitation to above said upper line of limitation;
wherein said body portion comprises a lobe immediately below said lower line of limitation and has a peripheral exterior length orthogonally about said longitudinal axis immediately below said lobe;
wherein said lobe has a lobe exterior length orthogonal to or about said longitudinal axis and said lobe exterior length is more than 5% of said peripheral exterior length; and
wherein said lobe has a lobe exterior height parallel to said longitudinal axis and said lobe has a lobe exterior length to lobe exterior height ratio greater than 1.

2. The container according to claim 1 , wherein said body portion comprises a plurality of said lobes.

3. The container according to claim 1 , wherein said container is a regular right prism.

4. The container according to claim 1 , wherein said container is a right circular cylinder.

5. The container according to claim 1 , wherein said body portion comprises two said lobes and said lobes are spaced apart from one another by straight segments of said lower line of limitation.

6. The container according to claim 1 , wherein said body portion comprises three or four said lobes spaced about said longitudinal axis.

7. The container according to claim 1 , wherein said body portion comprises a plurality of said lobes spaced apart from one another by from 10% to 80% of said peripheral exterior length.

8. The container according to claim 1 , wherein said core layer is discontinuous about said longitudinal axis.

9. The container according to claim 1 , wherein said lobe has a curved upper contour about said longitudinal axis.

10. The container according to claim 1 , wherein said core layer extends to a core rim above said upper line of limitation, wherein said container contains a plurality of articles comprising perfume, and said articles are filled in said container to a fill level below said core rim.

11. The container according to claim 1 , wherein said shell layer has an interior facing surface oriented towards said longitudinal axis, and wherein said interior facing surface above said lower line of limitation comprises at least one dosing indicia.

12. The container according to claim 1 , wherein said core layer extends to a core rim above said upper line of limitation, wherein said core rim is located at a rim distance from said shell bottom edge as measured parallel to said longitudinal axis and said rim distance is a function of position about said longitudinal axis, and wherein said core rim has a rim distance global maxima and a rim distance global minima ( 210 ) relative to said shell bottom edge.

13. The container according to claim 12 , wherein said longitudinal axis is between said global maxima and said global minima.

14. The container according to claim 12 , wherein said core rim is elliptical.

15. The container according to claims 12 , wherein said container further comprises a tear strip between said predetermined removable portion and said core layer and extending at least partially about said longitudinal axis, wherein said tear strip is joined to said predetermined removable portion, wherein said tear strip has an initiation end external to said container and said initiation end is within 40 degrees of said global minima as measured about said longitudinal axis.

16. The container according to claim 15 , wherein said body portion comprises two said lobes and said lobes are spaced apart from one another by straight segments of said lower line of limitation.

17. The container according to claim 12 , wherein said core layer is discontinuous about said longitudinal axis.

18. The container according to claim 12 , wherein said core layer extends to a core rim above said upper line of limitation, wherein said container contains a plurality of articles comprising perfume, and said articles are filled in said container to a fill level below said core rim.

19. The container according to claim 18 , wherein said shell layer has an interior facing surface oriented towards said longitudinal axis, and wherein said interior facing surface above said lower line of limitation comprises at least one dosing indicia.
