ABSTRACT:
A wedge shape folding carton is adapted for packaging individual slices of food product, preferably pizza slices. The blank for the wedge shape carton is generally trapezoidal in shape composed of three generally equilateral triangles positioned in juxtaposed serial spaced relation with the spacing between adjacent triangles filled by a pair of elongate rectangular size panels. A third elongate generally rectangular side panel extends from the base or free remaining side of the middle triangle. One of the end triangles has a cut-out portion formed on its base, and also has a generally rectangular fourth side panel extending from its remaining side. The middle triangle in the trapezoidal blank forms the bottom of the carton, the three rectangular side panels surrounding the bottom panel are folded perpendicular to the bottom panel to form the sides of the wedge shape carton, and the top of the carton is formed by bending the end triangle having the cut-out portion over the bottom triangle such that its fourth side panel is positioned in lapped relation with the side panel extending from the free side of the bottom triangular panel. The third triangular panel forms a cover for the cut out portion of the top triangle and is foldable over the top triangle and simply secured thereover by a tab and groove cut-outs in the top and cover triangles, respectively.
