  • Patent number: 6748722
    Abstract: A method for reducing heat loss of hot pizzeria pizza shipped in corrugated box packaging. The method involves placing a recently-cooked pizzeria pizza into a corrugated box having at least one tab-like structure projecting downward from a wall structure of the box and extending beyond a bottom edge of a wall panel by a distance of at least nine millimeters when the box is in a fully-erected format, whereby the method solves the problem of a downward-warping bottom panel of a loaded corrugated pizza box coming into contact with a cool support surface underneath the box.

  • Publication number: 20030211215
    Abstract: A method and system whereby a pizza company that makes pizzas from dough balls can create and control an optimal rate of proofing development for a plurality of dough balls disposed in various points, or stages, of proofing development. The method comprises the steps of (1) providing a computer-based dough ball management algorithm incorporating a dough ball proofing-progression measurement system, (2) periodically transmitting into the algorithm one or more dough ball usage values and one or more dough ball proofing-point inventory values, (3) periodically receiving computer-generated dough ball management information from the algorithm, and (4) based on the information, moving a particular quantity of dough balls of a particular point of proofing development from a refrigerated environment to a warm-air environment, resulting in the dough balls reaching a level of optimal proofing development by the time that they're needed for making into pizzas.
