Abstract
Abstract A container with a resealable sealing device consisting of a paper of foil blank and a sealing flap which can be produced inexpensively by means of die cutting. A pressure sensitive adhesive is used to make the sealing flap of the container resealable and the sealing flap is attached in a strong yet flexible manner. Die cut tear prevention holes are used to prevent the sealing flap from tearing away from the container.

A container with a resealable sealing device, comprising in combination, a container having an outer surface, an elongated inner flap, and an elongated sealing flap overlying said inner flap, said inner flap having a periphery with a forward and rearward portion, the forward portion of said periphery being cut out from said surface and terminating at said rearward portion, the rearward portion of said periphery being integrally attached to said surface along a line of attachment, said inner flap being pivotally liftable with respect to said outer surface along said line of attachment, said sealing flap having adhesive applied along one surface thereof and being attached onto said inner flap by means of said adhesive, said sealing flap being larger than said inner flap so as to define a peripheral border around said inner flap, said peripheral border including a front border portion, side border portions and a rear border portion, the rear border portion overlapping the rearward portion of said periphery of the inner flap, and being permanently attached to the outer surface of the container by means of said adhesive, a pair of opposing L-shaped cuts formed into said sealing flap commencing from opposing side edges thereof and partially extending into said side border portions of said sealing flap and then extending rearwardly toward the permanently attached rear border portion and terminating at said line of attachment, a first pair of tear prevention holes formed at the termination of said L-shaped cuts, and a second pair of tear prevention holes formed at the termination of said forward portion peripheral cut of said inner flap, all said tear prevention holes lying on said line of attachment, whereby said sealing flap can be pivotally lowered to replace said inner flap into its cut out and thereby seal the container by having the front border portion and the side border portions of said peripheral border of the sealing flap adhere to the container outer surface by means of said adhesive, and can pivotally be lifted to open the container without the permanently attached rear border portion lifting off and without said inner flap being detached.
