Abstract
The present invention relates to a composite container comprising a bottom film layer and a top film layer at least partially adhered to the bottom film layer. The top film layer is scored to form at least one resealable flap and at least one pull tab which is not adhered to the bottom film layer. The bottom film layer comprises at least one cavity opening. A cardboard layer is adhered on its lower surface to the upper surface of the top film layer, wherein the cardboard layer has at least one cavity opening which is substantially aligned with the scoring of the top film layer resealable flap and the cardboard layer is perforated to define a perimeter of at least one pull tab which is substantially aligned with and adhered, on its underside, to the upper surface of the top film layer pull tab.

A resealable container comprising a container body having at least four sidewalls, a top wall, and a bottom wall, wherein at least one of the walls has a composite structure which comprises:
- a bottom film layer;
- a top film layer at least partially adhered on its lower surface to the upper surface of the bottom film layer, wherein:
- the top film layer is scored to form at least one resealable flap and at least one pull tab continuous with the resealable flap, wherein the resealable flap is resealably adhered to the bottom film layer and the pull tab is not adhered to the bottom film layer;
- and
- the bottom film layer comprises at least one cavity opening;

- an unaffixed portion, in which the top film layer and the bottom film layer are separate from each other,
- an overcut formed in the top film layer along at least a portion of an outer periphery of the releasably affixed portion to form a flap and a pull tab, wherein the pull tab is disposed within the unaffixed portion, and
- an undercut formed in the bottom film layer along at least a portion of an inner periphery of the releasably affixed portion;
- and
- a fibrous material layer forming an interior cavity for storing items, comprising an opening which provides access to the interior cavity wherein:
- the opening is substantially aligned with the inner periphery of the releasably affixed portion of the film,
