Abstract

A reclosable container made of a semi-rigid paperboard material or the like has a lower component with a bottom panel and an upstanding side wall and an upper component or lid that is pivotally connected to the lower component along one edge thereof. An opposite edge of the lid component has a tab formed therein which can be punched out and folded inwardly relative to the lid to releasably engage a horizontal extension or catch formed along the corresponding top edge of the lower component of the container.

Claims

1. A reclosable container formed from a semi-rigid material comprising in combination:

a lower component having a bottom panel and a side wall connected to and projecting upwardly from the bottom panel, said side wall having an upper edge and a catch defined by a substantially perpendicular extension from said side wall along said upper edge, said extension having a bottom surface, and

an upper component adapted to overlie the lower component, said upper component having a top panel with a downwardly directed flange, said flange having an integrated tab formed thereon, said tab having a top edge defined by a fold line, and a remaining edge defined along a perforated line in said flange such that said tab can be folded inwardly along said fold line after said perforated line has been severed such that at least a portion of said remaining edge is directed substantially upwardly and positioned to engage said bottom surface of said extension when said upper component of the container is positioned over said lower component.

2. The container of claim 1 further including a pivotal connection between said upper component and said lower component.

3. The container of claim 2 wherein said pivotal connection is on an opposite side of said container from said catch.

4. The container of claim 3 wherein said flange is secured to said side wall adjacent to said tab and said flange further includes a tear away strip allowing said flange to be separated from said side wall adjacent to said tab.

5. The container of claim 1 wherein said container is formed from a flat blank of said semi-rigid material and wherein said catch is defined within the portion of said blank from which said side wall is formed and has a perforated line defining an edge of said catch which perforated line is at least partially severable to permit said catch to be formed from said side wall when the container is formed from said blank.

6. The container of claim 1 wherein said side wall has four perpendicular panels, each panel of said side wall being perpendicular to said bottom panel and having an panel upper edge which cooperates with the other panel upper edges in forming said upper edge of the lower component in a quadrilateral configuration.

7. The container of claim 6 wherein said upper component includes a quadrilateral top panel and said downwardly directed flange is comprised of three panel flanges, each panel flange disposed perpendicularly to an edge of said top panel with the fourth edge of said top panel defining a hinged connection with an associated one of said panel upper edges.

8. The container of claim 7 wherein said tab is formed in the panel flange opposite said hinged connection.

9. The container of claim 8 wherein said catch is positioned on the panel upper edge opposite said hinged connection.

10. The container of claim 1 wherein said downwardly directed flange has a lower edge and wherein said tab is spaced upwardly from said lower edge.

11. The container of claim 5 wherein the perforations in said perforated line defining an edge of said catch extend only partially through said semi-rigid material.

12. The container of claim 11 wherein said catch is formed from a delaminated layer of said side wall.

13. The container of claim 5 wherein the perforations in said perforated line defining an edge of said catch extend completely through said semi-rigid material.

14. The container of claim 13 wherein said catch is formed from the fill thickness of said side wall.
