Abstract

A generally rectangular blank of preferably cardboard material having a multitude of strategically positioned cut lines, fold lines, and perforated tear lines. The present invention can be formed into at least two differently shaped and sized boxes; thus, efficiently accommodating a whole pizza in its original rectangular shape, and efficiently accommodating a slice or other portion of pizza in its reduced-size, triangular shape. In addition to the typical cut and fold lines found in a common pizza box, the present invention provides, generally, eight sets of perforated tear lines strategically positioned such that a rectangularly-shaped pizza box may be torn along the perforated tear lines to form a generally triangularly-shaped, smaller dimensioned pizza box.

A variable sized and shaped pizza box, comprising:

a blank of material for forming an approximately rectangular pizza box;
a plurality of fold lines formed in said blank of material for forming said pizza box with a top, a bottom, two bottom side walls, a bottom front side wall, two top side walls, and a top front side wall, and further comprising two spaced-apart fold lines formed near the center of the blank for forming a rear side wall;
and,
a plurality of tear lines formed in said blank of material and disposed so as to enable separation of said blank along said tear lines such that said approximately rectangular pizza box may be reconfigured into an approximately triangular pizza box, said plurality of tear lines further comprising:
a first tear line beginning approximately at one side edge of the pizza box and extending approximately along and parallel with the fold line proximal to the front edge, to a predetermined point which is located at a distance equal to approximately twice the height of a side wall of the box;
a second tear line extending from said point at approximately a 135-degree angle and extending to the fold line formed proximal to the opposite side edge of the pizza box;
a third tear line located at approximately the mid-point between the two side edges, said third tear line interrupting said second tear line by forming a generally U-shaped tab portion extending generally downward from, and perpendicular to, said second tear line;
a fourth tear line extending upwardly from the end of said second tear line and approximately along the fold line to approximately the first spaced-apart fold line formed near the center of the blank for forming the rear side wall of the pizza box when folded;
a fifth tear line extending outward to the proximal side edge;
a sixth tear line beginning approximately at the intersection of the second spaced-apart fold line formed near the center and the side edge fold line proximal thereto, and extending upwardly along said side edge fold line a predetermined distance equal to approximately the height of a side wall of the box;
a seventh tear line extending therefrom at approximately a 45-degree angle until said seventh tear line intersects the fold line proximal to the rear edge of the blank;
and,
an eighth tear line extending generally along the fold line proximal to the rear edge to the same side edge as the first tear line begins.

A variable sized and shaped pizza box, comprising:

an approximately rectangular blank of material, said blank further comprising fold lines formed near the edges thereof and spaced a distance therefrom, said fold lines being disposed for forming the pizza box with a top, a bottom, two bottom side walls, a bottom front side wall, two top side walls, and a top front side wall, and further comprising two spaced-apart fold lines formed near the center of the blank for forming a rear side wall;
said blank further comprising a plurality of tear lines, said plurality of tear lines comprising:
a first tear line beginning approximately at one side edge of the pizza box and extending approximately along and parallel with the fold line proximal to the front edge, to a predetermined point which is located at a distance equal to approximately twice the height of a side wall of the box;
a second tear line extending from said point at approximately a 135-degree angle and extending to the fold line formed proximal to the opposite side edge of the pizza box;
a third tear line located at approximately the mid-point between the two side edges, said third tear line interrupting said second tear line by forming a generally U-shaped tab portion extending generally downward from, and perpendicular to, said second tear line;
a fourth tear line extending upwardly from the end of said second tear line and approximately along the fold line to approximately the first spaced-apart fold line formed near the center of the blank for forming the rear side wall of the pizza box when folded;
a fifth tear line extending outward to the proximal side edge;
a sixth tear line beginning approximately at the intersection of the second spaced-apart fold line formed near the center and the side edge fold line proximal thereto, and extending upwardly along said side edge fold line a predetermined distance equal to approximately the height of a side wall of the box;
a seventh tear line extending therefrom at approximately a 45-degree angle until said seventh tear line intersects the fold line proximal to the rear edge of the blank;
and,
an eighth tear line extending generally along the fold line proximal to the rear edge to the same side edge as the first tear line begins;
wherein when said pizza box is folded about said fold lines, said pizza box is rectangular shaped, and wherein when said blank of material is torn about said tear lines and folded about said fold lines, said pizza box is triangularly shaped.
