    摘要： An improved container for storing and transporting a hot pizza product that includes a top and bottom with nonzero Gauss curvatured structures over a major portion of the supporting surface so that less material need be used for fabrication without a lowering of structural integrity. The top and bottom members are adapted to nest with other like tops and bottom members to reduce the need storage space near the pizza oven where they are ready for use without preassembly. The floor of the bottom comprises upstanding projections with small top surface area to reduce the heat conduction path and to support the product above the floor to form an air insulating space between the product and the floor. The bottom member includes a sidewall that intersects the floor to form a supporting line when resting on a supporting surface, thermal conduction being limited to such line. The curved, convex shape of the floor then provides a closed air insulating space between the bottom and the resting surface. Channels are provided in the top and bottom for rigidity and to assist cutting the product and nesting completely assembled boxes for transport. Other features are disclosed.

    摘要： A method of separation from a stack of sheets a block of predetermined number of sheets, the method including retaining the stack so that a portion of one edge of each consecutive foremost sheet is free to bend away from the stack, directing a plane of air flow sequentially on to the foremost surfaces of a predetermined number of foremost sheets to bend at least a portion of the free edge of each of the predetermined number of foremost sheets away from the stack, separating the bent predetermined number of foremost sheets into a block and removing the block from the remaining sheets in the stack. Preferably, the plane of the air flow intersects the plane of the sheets in the stack in the range of 5.degree.-10.degree.. The plane of the air flow can be directed to bend the free edge or just the corners of sheets in the block to be separated. In one example, the stack foremost end is inclined downward and the air flow is directed upward.
