Abstract

A reclosable food container is created from a unitary blank. The container includes a bottom panel, a pair of opposing end panels extending from the first bottom panel, a lateral side panel extending from the first bottom panel, and an opposing side panel extending from the bottom panel on an opposing side to the lateral side panel. The container also includes a plurality of foldable gussets, where each gusset hingedly connects a side panel-end panel pair. The container also includes a lid extending from the lateral side panel, where the lid includes a top panel and a tuck flap. There is a score line between at least one of the lateral side panel and the top panel, and the top panel and the tuck flap. The score line has a ratio of penetration between about 0.1 and about 0.9.

Claims

1. A reclosable food container created from a unitary blank, the container comprising:

a bottom panel;

a pair of opposing end panels extending from the bottom panel;

a lateral side panel extending from the bottom panel;

an opposing side panel extending from the bottom panel on an opposing side to the lateral side panel;

a plurality of foldable gussets, each gusset hingedly connecting a side panel-end panel pair;

a lid extending from the lateral side panel, the lid comprising a top panel and a tuck flap;

a score line between at least one of the lateral side panel and the top panel, and the top panel and the tuck flap, wherein the score line has a ratio of penetration between about 0.1 and about 0.9.

2. The food container of claim 1 wherein each opposing end panel further comprises a splash guard flap extending therefrom.

3. The food container of claim 2 wherein the tuck flap of the lid engages the splash guard flaps when the lid is in a dosed orientation.

4. The reclosable food container of claim 3 further comprising:

a pair of locking slits formed at opposite edges of a junction between the top panel and the tuck flap;

wherein the locking slits increase a retention strength of the engagement between the respective opposing splash guard flaps when the lid is in a closed orientation.

5. The food container of claim 1 wherein the side panels and end panels slope upward at a predetermined angle from the bottom panel such that a pair of food containers are nestable one within another.

6. The food container of claim 1 wherein respective ones of the panels are defined on the blank by fold lines.

7. The food container of claim 1 wherein the score line has a ratio of penetration between about 0.3 and about 0.7.

8. The food container of claim 1 wherein the score line has a ratio of penetration between about 0.45 and about 0.55.

9. The food container of claim 1 wherein the score line has a ratio of penetration about 0.5.

10. The food container of claim 1 wherein the score line has a ratio of a length between an unscored portion and a scored portion between about 0.1 and about 0.5.

11. The food container of claim 1 wherein the score line has a ratio of a length between an unscored portion and a scored portion between about 0.15 and about 0.25.

12. The food container of claim 1 wherein the score line has a ratio of a length between an unscored portion and a scored portion of about 0.2.

13. The food container of claim 1, wherein the opposing side panel further comprises a locking tab mechanism, and the tuck flap further comprises a locking slot mechanism.

14. The food container of claim 13, wherein the lid engages at least one of the opposing side, the pair of opposing hinge panels, and the locking tab mechanism when in a closed orientation.
