Abstract

A leak proof container and a method of forming the container from a blank. The blank includes a bottom panel, first and second side panels connected to the bottom panel at opposing lateral edges, and first and second end portions located at opposing longitudinal ends of the blank. Each end portion includes an inner end panel connected to the bottom panel, an outer end panel connected to the inner end panel, and first and second corner panels forming gussets connected to a respective one of the first and second side panels and connected to the inner end panel. An adhesive area is located on one side of the blank and comprises at least a portion on each of the outer end panel and the inner end panel. The adhesive area adheres the gussets to the inner end panel and to the outer end panel.

First claim

What is claimed is:

1. A blank for making a leak proof container, the blank having an inner side and an outer side and comprising:
a bottom panel having a plurality of peripheral edges;
first and second side panels connected to the bottom panel at opposing lateral peripheral edges and defining lower edges of the container;
first and second end portions located at opposing longitudinal ends of the blank, each end portion including:
an inner end panel connected to a longitudinal peripheral edge of the bottom panel;
an outer end panel having an inner longitudinal edge hingedly connected to a longitudinal edge of the inner end panel;
first and second corner panels, each corner panel having a longitudinal edge connected to a respective one of the first and second side panels and a lateral edge connected to a lateral edge of the inner end panel; and
an adhesive area located on one side of the blank and comprising at least a portion on each of the outer end panel and the inner end panel, wherein the adhesive area extends longitudinally generally continuously from the outer end panel to the inner end panel.

2. The blank as set forth in claim 1 , wherein the adhesive area comprises first and second laterally spaced adhesive areas.

3. The blank as set forth in claim 2 , wherein the first and second adhesive areas include outer lateral edges located adjacent to respective lateral edges of the outer end panels and adjacent to respective lateral edges of the inner end panels.

4. The blank as set forth in claim 3 , wherein the adhesive areas each include an inner lateral edge, parallel to the outer lateral edges of the adhesive areas, and an inner longitudinal edge having at least a portion defining an angled corner forming an obtuse angle extending from a respective inner lateral edge.

5. The blank as set forth in claim 2 , wherein the first and second adhesive areas extend longitudinally generally continuously from the outer end panel to the inner end panel.

6. The blank as set forth in claim 2 , wherein the adhesive areas are defined by an application of hot melt glue.

7. The blank as set forth in claim 1 , wherein the corner panels are formed as square panels, and including a diagonal fold line dividing each corner panel into first and second triangular gusset panels.

8. The blank as set forth in claim 7 , wherein each corner panel includes a lateral edge that is colinear with a lateral edge of the blank defined by an edge of one of the first and second side panels.

9. The blank as set forth in claim 1 , wherein a longitudinal dimension of the outer end panel is substantially less than a longitudinal dimension of the inner end panel.

10. The blank as set forth in claim 1 , wherein the adhesive area is located on the outer side of the blank.

11. The blank as set forth in claim 1 , wherein the adhesive area is located on the inner side of the blank.

12. The container as set forth in claim 1 , wherein a gusset fold line extends from the bottom of the container to the inner longitudinal edge of the outer end panel.
