Patent number: 5465654Abstract: 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.Type: GrantFiled: November 19, 1993Date of Patent: November 14, 1995Assignee: Food and Agrosystems, Inc.Inventors: Rauno A. Lampi, John N. Bindon, Anthony J. G. Bowles, Thomas R. Parks

Patent number: 5442998Abstract: 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.Type: GrantFiled: November 23, 1993Date of Patent: August 22, 1995Inventor: Karl Niese

Patent number: 5441169Abstract: A saucepan of the double boiler type. The saucepan includes a lower water receptacle, an upper food receptacle and an attached handle. The handle defines an enclosed fill chamber which communicates with the lower water receptacle via a hole. A cap is connected to the handle by an over center hinge and covers a fill hole through which water may be introduced into the chamber and thence to the water receptacle. The cap may have a hole therein to provide an aural indicator of water boiling in the water receptacle.Type: GrantFiled: January 10, 1994Date of Patent: August 15, 1995Inventor: Christopher K. Petty

Patent number: 5430928Abstract: In order to fix a perforated plate (2) to the bottom (1) of a vessel, the plate is fixed by closed-die forging, in particular by cold striking so as to make the metal of the bottom (1) penetrate into the openings (4) in the plate (2). At the same time as the closed-die forging operation, a series of reliefs (5) is formed on the surface of the perforated plate (2) as well as on the surface of the bottom (1) of the vessel.Type: GrantFiled: March 3, 1994Date of Patent: July 11, 1995Assignee: SEB S.A.Inventor: Denis Flammang

Patent number: 5404800Abstract: In accordance with this invention, a convection oven rack is provided which includes a base portion and a plurality of bracket portions attached thereto. Each bracket has a curved interior side that corresponds to the exterior curved shape of a cooking dish insertable between the brackets and on top of the base portion. Attached to the second end of each bracket is a handle portion for gripping. A plurality of padded insulating pads are positioned on the top side of the base portion and the interior side wall of the brackets. In operation, the rack remains attached to the dish during cooking. When cooking is completed, the lid of the dish, which houses a fan and cooking element, is removed so that the rack serves as an insulated holding means whereby food may be served directly from the dish.Type: GrantFiled: May 6, 1994Date of Patent: April 11, 1995Assignee: Airlux Electrical Co., Ltd.Inventor: Maxwell Hsu

Patent number: 5402714Abstract: A fork segregating partitioning array for use with a fondue pot. The fondue pot is of the type defining a container with a large cavity to receive meltable foodstuff to be warmed by a heating source. The partitioning array consists of a cup member, freely releasably engageable into the container large cavity, and at least two partitioning walls disposed in crossing fashion relative to one another, whereby four distinct subcavities are defined within the cup member. The subcavities are for use in segregating a corresponding number of forks in cooking fondues such as meat fondue or chinese fondue. The cup member is further pierced by a plurality of through-bores, for free passage of the meat soup between the fondue pot and the cup member and vice-versa.Type: GrantFiled: July 19, 1993Date of Patent: April 4, 1995Inventors: Robert Deneault, Pierre Vigneault

Patent number: 5392948Abstract: A nestable, stackable mixing bowl is provided having a radiused sidewall and a wide concave rim flange. The rim flange provides a handle around the entire circumference of the bowl, providing an easy way to grasp the bowl while pouring. The rim flange is provided with three integral equidistantly spaced pourspouts, thus requiring less manipulation for positioning the bowl for pouring. The bottom of the bowl is provided with an annular rib to provide stability to the bowl. The bowl is also provided with a lid shaped to cover the bowl and to accept the rim flange. The lid has a central circular depressed portion sized to matingly engage the bottom rib of a smaller capacity bowl, providing stable stacking.Type: GrantFiled: May 19, 1994Date of Patent: February 28, 1995Assignee: Tucker HousewaresInventor: Kathy McEntee
