ABSTRACT:
A tear open and relockable cardboard container is disclosed comprising a first and a second top member having a first and a second top fold and a first and a second top edge which top members are secured in an overlapping relationship to form a top of the container. The first top member has a container aperture perforation with a locking projection extending toward the first edge. Locking slots extend from the sides of the container aperture perforation. The second member has a first and a second perforation with a lift tab fold line extending between the first and second perforation defining a lift tab therebetween. A lift tab perforation is located on the second top member and intersects the lift tab fold line forming a reopen tab. The container is opened by raising the lift tab to expose the container aperture. The container is relocked by inserting the lift tab into the locking slots with the locking projection extending through the lift tab perforation resulting in a first engagement between the lift tab and the bottom surface of the first member and resulting in a second engagement between the reopen tab and the top surface of the first member. The lift tab forms an obtuse angle with the second member resulting in an increase in the force of the first and second engagements by the weight of the contents of the container upon the lift tab when the container is overturned. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
