ABSTRACT:
A folded wrapper for a food product such as a taco or sandwich, the wrapper formed from a unitary circular blank of paperboard. In order to accommodate the thickness of the food product without squeezing it, the wrapper is provided with two major parallel fold lines at a generally diametrical fold location. The spacing between these lines is generally that of the thickness of the food product. When folded however about these fold lines, the wrapper would fold about only one or the other of them, thereby squeezing the product. Further, the ends of the folds would be open and thus permit pastes of other semi-liquid or liquid components of the product to escape. To seal the ends of the fold, and also to prevent folding about only one of the major parallel pairs of fold lines, the major parallel fold lines are shortened and a pair of shorter fold lines, located midway of the parallel fold lines and extending radially inwardly from the wrapper periphery, are provided. The wrapper is releasably latched at the peripheries of the two folded halves by interengaging ears and slots.
