Paper based container for household products
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 core layer has a core rim located at a rim distance that is a function of position about the longitudinal axis of the container.
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 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 pour spout having a rim distance global maxima and a rim distance global minima relative to said shell bottom edge;
wherein at any position about said longitudinal axis said cap portion has a cap portion height measured parallel to said longitudinal axis between said upper line of limitation and said shell top edge and said predetermined removeable portion has a predetermined removeable portion maximum height measured parallel to said longitudinal axis and said cap portion height is greater than said predetermined removable portion maximum height.
2. The container according to claim 1 , wherein said longitudinal axis is between said global maxima and said global minima.
3. The container according to claim 1 , wherein said core rim is elliptical.
4. The container according to claim 1 , wherein said core rim is parallel to a plane oriented at an angle that is more than five degrees out of plane with respect to said shell bottom edge.
5. The container according to claim 1 , 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.
6. The container according to claim 1 , wherein said shell layer comprises a weakly connected longitudinal seam extending at least partway between said shell bottom edge and said shell top edge.
7. The container according to claim 6 , wherein said longitudinal seam is within 40 degrees of said global minima as measured about said longitudinal axis.
8. The container according to claim 1 , wherein said container is a right circular cylinder.
9. The container according to claim 1 , wherein said core layer is discontinuous about said longitudinal axis.
10. The container according to claim 9 , wherein said core layer is discontinuous about said longitudinal axis at a location within 40 degrees of said global minima as measured about said longitudinal axis.
11. The container according to claim 1 , wherein said body portion has a peripheral exterior length orthogonally about said longitudinal axis immediately below said lower line of limitation, and wherein at said rim distance global minima said core layer extends above said upper line of limitation by from 5% to 50% of said peripheral exterior length.
12. 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.
13. The container according to claim 1 , wherein said container contains a plurality of articles, wherein said articles comprise perfume.
14. The container according to claim 1 , wherein said core rim is elliptical and wherein said core rim is parallel to a plane oriented at an angle that is more than five degrees out of plane with respect to said shell bottom edge.
15. The container according to claim 14 , wherein said core layer is discontinuous about said longitudinal axis.
16. The container according to claim 15 , wherein said shell layer has an interior facing surface ( 240 ) oriented towards said longitudinal axis, and wherein said interior facing surface above said lower line of limitation comprises at least one dosing indicia.
17. The container according to claim 16 , wherein said container contains a plurality of articles, wherein said articles comprise perfume.
