  • Patent number: 5779080
    Abstract: The invention features a multi-purpose baking pan having a pan portion for holding batter. A pastry holder is included to allow the user to bake differently-shaped pastries which can be inserted into the pan portion. The pan portion has a rectangular bottom wall with two side walls which extend integrally in the same direction from the bottom wall along the opposite edges. There are two end members, located at the short sides of the rectangular bottom, which each have a rod-like hinge pin. Rotating an end member, by grasping and raising the lower portion thereof, allows the user to slide out the pastry holder without damage to the pastries or to the user. The multi-purpose baking pan also has a cover to protect the pastries within the baking pan.

  • Patent number: 5775208
    Abstract: A pizza pan system includes a pizza pan including a bottom wall, a side wall circumferentially about the bottom wall such that the bottom wall and side wall cooperate to define an area for containing pizza dough, and a rim circumferentially about the outer edge of the side wall; and a lid-like member mating with said rim enabling pizza dough to be compressed between said lid-like member and said rim to produce single-crusted, fold-over or double-crusted pizzas. The system allows storage of panned pizza dough within a substantially air tight chamber. The pans of the system can be stacked to economize on countertop or storage space. The area for confining pizza dough allows, in conjunction with a trimming means, consistent reproduction of aesthetically pleasing pizza shapes. A method of preparing pizza includes rolling dough, placing the dough in a pizza pan, and placing a lid over the pizza pan to compress, shape, conform and trim dough about a rim area of the pizza pan and lid.

  • Patent number: 5730045
    Abstract: The present invention relates to a cooking apparatus to facilitate straining requirements. The cooking apparatus includes a pot and lid that can be securely integrated to function as a strainer. The lid includes a circumferentially extending flange that is designed to slide into the pot and rest on the rim of the pot. The flange includes a pair of opposing perforation regions and a pair of opposing protrusion elements. The pot includes a corresponding pair of notches and channels to receiving the protrusion elements to secure the lid to the pot. In a straining position the lid is secured to the pot, with the protrusion elements positioned in the channels and with the perforations regions aligned with dipped outer edges in the rim of the pot to facilitate pouring and straining. In a non-straining position the lid is merely resting in the notches to permit easy removal of the lid.

  • Patent number: 5730308
    Abstract: A closure for covering the opening of a vessel containing a supply of cooking fluid preferably includes a flexible inner member adapted to cover the opening of the vessel in sealing engagement therewith and an outer member adapted to be positioned above the inner member. A coupling assembly is provided to couple the inner member to the outer member when the closure assembly is removed from the vessel. The coupling assembly permits a portion of the inner member to expand away from the outer member in response to an increase in temperature within the cooking vessel. The inner member is preferably a low thermal conductivity material so that after the inner surface of the inner member, which is exposed to vaporized cooking fluid, reaches the temperature of the vapor condensing thereon, the rate of additional condensation is substantially reduced. The vapor conserved by reduced condensation on the inner surface is used to generate pressure in the vessel more rapidly.

  • Patent number: 5564590
    Abstract: A cooking vessel having a multiple bottom structure. The cooking vessel strengthens the structure of a bottom plate, made of copper, copper alloy, aluminum or aluminum alloy, by simple insertion of a reinforcing member on the bottom plate. The reinforcing member is made of a ferrous metal or a nonferrous metal different from the material of the bottom plate. With the difference of heat conduction between the bottom plate and the reinforcing means made of different materials, the heat transfer rate, the heat conductivity and the heat preservation of the vessel bottom are remarkably improved. When the reinforcing member is magnetized, the cooking vessel can be used with an induction heater. The reinforcing member is inserted in the bottom plate such that its bottom is leveled with a bottom surface of the bottom plate. In production of the cooking vessel, the bottom plate is preheated to temperatures ranged from 470.degree. C. to 490.degree. C.

  • Patent number: 5507220
    Abstract: A cooking utensil having three layer member includes a thermal retaining space between the intermediate member and the outer member, an air passage formed vertically in a part of the circumference between the side walls of the outer member and the intermediate member, and which is communicated with the heat retaining space, and a thermal retaining activator mounted on the exit of the air passage, and which selectively communicates the space with the atmosphere or not. Air in the heat retaining space is heated by heat transmitted from the outer member and the intermediate member made of material having high thermal conductively is indirectly heated by heat transmitted from the air in the space. Therefore heat energy of the intermediate member is uniformly spread out throughout the whole surface thereof so that heat is not focused at any part of the intermediate member and the food in the inner member which is closedly contacted with the intermediate member is not scorched or burned.

  • Patent number: 5503062
    Abstract: The invention is a reinforcing support structure for a pan adapted to contain an object. The pan has a pan bottom and a sidewall extending upwardly from the periphery of the pan bottom. An outwardly extending rim is formed on the upwardly extending sidewall around the entire circumference of the pan. An outer support for holding the pan has an upper support portion and a lower support portion. The upper support portion is applied to the entire outwardly extending rim of the pan to support and reinforce the extending rim. The lower support portion also includes a plurality of horizontal support members wherein at least one of the horizontal support members is formed in a zigzag shape. An object support rack is disposed within the pan to support the object when the object is disposed in the pan. The object support rack includes a spacer for spacing the object apart from the pan bottom.

  • Patent number: 5465654
    Abstract: A convenient serving-size pan (10) with flange (13), and flanged lid (11) removably attached by a hinge (14), enabling a wide range of pourable, particulate, and solid foods to be cooked in quantity in forced-air convection ovens. The pan and lid are fabricated of highly heat conductive materials with interior surfaces suitable for direct food contact. Exterior surfaces of the pans are smooth and plain to minimize insulative film coefficients and maximize heat transfer. A vertical stacking system provides effective use of oven space while maintaining sufficient space between pans for effective heat transfer.

  • Patent number: 5442998
    Abstract: A pressure cooker has a lid displaceable in the vertical direction with respect to the cooker to reduce the residual pressure in the cooker and to permit opening of the cooker without any rotary movement. Tongues projecting downwards between the dome edge and the cooker edge, in conjunction with guide slots provided in clips which hold together the cooker and the lid ensure radial opening and closing movements of the clips. A centering ring located in the dome and extending into the cooker facilitates the engagement of the lid on the cooker. The centering ring carries the sealing ring and the tongues and is based away from the dome by springs supported on the dome. The dome and the centering ring are guided on one another by interengaging elements and can be locked together in the open position.
