Abstract
A box of the type to hold pies, such as pizza pies, which comprises a basic cardboard structure and a restrainer in an inactive form. When the box has been used for its purpose and it is time to be disposed of, the box is destructively folded into a log-shaped structure, which is prevented from spontaneously unfolding by activation of the restrainer.
Claims12
A box assembly comprising:
- a cardboard box;
- and
- a restrainer in an inactive status, the restrainer being adaptable to assist the cardboard box in retaining a folded position after said cardboard box
- has been used to hold an item,
- has been destructively folded to form a log-shaped structure in order to be discarded, and
- after the restrainer has been activated:
- with the requirement that
- (a) the restrainer comprises an opening and an extension adaptable to fit in the opening, and
- (b) the cardboard box comprises destructive latent folding lines, the destructive latent folding lines arranged at such intervals from each other, so that when the cardboard box structure is destructively folded around said latent lines, said cardboard box structure allows the restrainer to be activated by an operator positioning the extension into the opening.

A box assembly comprising:
- a cardboard box;
- and
- a restrainer in an inactive status, the restrainer being adaptable to assist the cardboard box in retaining a folded position after said cardboard box
- has been used to hold an item,
- has been destructively folded to form a log-shaped structure in order to be discarded, and
- after the restrainer has been activated;
- with the requirement that
- (a) the restrainer is an integral part of the cardboard box structure.
- (b) the restrainer comprises an opening on the cardboard box and an extension adaptable to fit in the opening,
- (c) the cardboard box further comprises latent folding lines, the latent lines arranged at such intervals from each other, so that when the cardboard box is destructively folded around said latent lines, said cardboard box allows the restrainer to be activated by an operator positioning the extension into the opening.

A combination comprising:
- a box assembly and a pie contained in the box assembly
- the box assembly comprising:
- a cardboard box;
- and
- a restrainer in an inactive status, the restrainer being adaptable to assist the cardboard box in retaining a folded position after said cardboard box
- has been used to hold an item,
- has been destructively folded to form a log-shaped structure in order to be discarded, and

A combination comprising:
- a box assembly and an item contained within said box assembly:
- the box assembly comprising
- a cardboard box having a front side;
- and
- a restrainer in an inactive status, the restrainer being adaptable to assist the cardboard box in retaining a folded position after said cardboard box
- has been used to hold the item,
- has been destructively folded to form a log-shaped structure in order to be discarded, and
- the restrainer has been activated;
- with the requirement that
