Abstract

A convolute paperboard container comprising a closed bottom, and an upstanding continuous sidewall extending from the bottom and terminating in an upper rim. The container when viewed transversely of its longitudinal axis is curvilinear oblong or oval in shape such that the sidewall comprises broad front and back panels connected by curved side panels of a reduced radius of curvature. A side seam extending vertically from the bottom of the container to its upper rim is positioned along the sidewall in an offset position such that a major portion of the front and back sidewall panels remains uninterrupted by the side seam for purposes of displaying marketing and/or instructional indicia.

Claims

1. A container for storing and packaging dry, semi-dry or liquid goods, said container having a longitudinal axis and comprising:

a closed bottom;

an upstanding sidewall wrapped about said longitudinal axis of the container and extending from the closed bottom to form a storage cavity, wherein said sidewall forms a curvilinear and oblong perimeter about the container storage cavity when viewed transversely of the longitudinal axis of said container, said perimeter being defined by a major axis a of greater length than a minor axis b and said sidewall comprising a broad front panel connected to a broad back panel by curved side panels, wherein each of said curved side panels has a smaller radius of curvature than said broad front and back panels; and

an offset side seam extending longitudinally along said upstanding sidewall such that said side seam is positioned within one of said curved side panels remote from a line of intersection between said major axis a and said sidewall.

2. A container in accordance with claim 1, wherein said container is formed of paperboard.

3. A container in accordance with claim 1, wherein said sidewall and closed bottom together form a cavity accessible through an open top bounded by an upper rim.

4. A container in accordance with claim 3, wherein said container includes a closure lid adapted to releasably close said open top.

5. A container in accordance to claim 4, wherein said closure lid comprises a reusable lid which is adapted for repeated closure of said open top.

6. A container in accordance to claim 4, wherein said closure lid comprises a disposable ring pull lid.

7. A container in accordance with claim 3, wherein said container additionally comprises a tamper evident sealing membrane applied to the container along said upper rim.

8. A container in accordance with claim 7, wherein said tamper evident/sealing membrane is formed of a flexible material selected from the group consisting of foil, paper, plastic, or laminate.

9. A container in accordance with claim 2, wherein said paperboard is coated with a barrier material.

10. A container in accordance with claim 9, wherein said barrier material is selected from the group consisting of a heat sealable plastic material.

11. A container in accordance with claim 1, wherein said offset side seam is positioned within one of said curved side panels at an angle ranging from 30°

to 70°

from the line of intersection of major axis a and said sidewall, said angle being measured from a center of the radius of curvature of the curved side panel.

12. A container in accordance with claim 11, wherein said offset side seam is positioned within one of said curved side panels at an angle of about 45°

from the line of intersection of major axis a and said sidewall.

13. A container for storing and packaging dry, semi-dry or liquid goods, said container having a longitudinal axis and comprising:

a closed bottom having an outer periphery that is curvilinear in shape;

an upstanding sidewall extending upward from the outer periphery of said closed bottom and terminating in an upper rim such that the sidewall and closed bottom together define a cavity accessible through an open top bounded by said upper rim, the sidewall being formed from a sheet of paperboard wrapped about the longitudinal axis of said container, said sheet of paperboard including side edges that are secured together in overlapping relation to form a side seam extending from said closed bottom to said upper rim, the container when viewed transverse of said longitudinal axis forms a perimeter around the cavity that is curvilinear and oblong in shape, said perimeter being defined by a major axis a having a greater length than a minor axis b and said sidewall comprising a broad front panel connected to a broad back panel by curved side panels wherein the curved side panels have a radius of curvature that is less than the radius of curvature of the broad front and back panels, and wherein the side seam is in an offset position along said sidewall such that the side seam extends within one of said curved side panels remote from a line of intersection between the major axis a and the sidewall.

14. A container in accordance with claim 13, wherein said offset side seam is positioned within one of said curved side panels at an angle ranging from 30°

to 70°

from the line of intersection of major axis a and said sidewall, said angle being measured from a center of the radius of curvature of the curved side panel.

15. A container in accordance with claim 14, wherein said offset side seam is positioned within one of said curved side panels at an angle of about 45°

from the intersection of major axis a and said sidewall.
