  • Patent number: 9078539
    Abstract: Cookware comprising a selectively bonded composite of at least two layers of materials wherein the first of the at least two layers of materials has a plurality of spaced-apart bubbles formed on its surface, defining a cooking surface of the cookware, and a second layer of two layers of material is bonded thereto, wherein the bonding between the bubbles and the second material is of a lesser degree than the bonding between the first and second layers of materials in areas intermediate the bubbles, whereby a coefficient of heat conductivity is greater in the intermediate areas than in the bubbles.

  • Patent number: 9060639
    Abstract: Cookware, such as a stock pot, fry pan, sauté pan, griddle, or grill, comprising a basic three-ply bonded composite includes two layers of an aluminum alloy, such as 3003 or the like, bonded on opposed sides to a core layer of higher purity aluminum, such as 1050, 1100, 1145, or the like, to define a three-ply composite cookware product. One or more additional layers of higher purity aluminum are bonded intermediate one or more additional layers of aluminum alloy to form five-ply, or seven-ply, or more, bonded composite cookware products. The exterior layers of aluminum alloy may also include a non-stick coating and/or an anodized coating.

  • Publication number: 20130119069
    Abstract: A device for holding a lid to a pot to permit the pouring of liquid from the pot while retaining a food product within the pot, including a pair of spaced apart hook members attached to opposed top edges of the pot and positioned off-set from a centerline of the pot. The hook members each include a horizontal top flange turned inwardly toward the pot, whereby when the pot is moved to a pouring position, the liquid forces the lid to separate from the pot and the top flanges of the hook members to engage the lid to maintain a predetermined pouring gap between the lid and the pot and also to prevent the lid from sliding forward off the pot due to their off-set positioning from the pot centerline.

  • Patent number: 8137732
    Abstract: A flavor infusion device for roasting poultry, such as chicken, comprising an elongated metal member having an attachment means at one end for attachment to a sidewall of a roasting pan, a radiused bent portion extending upwardly from the attachment means, and a horizontal arm portion extending from the radiused bent portion in a substantially horizontal orientation relative to the roasting pan to support an open cavity of the poultry, said horizontal arm portion having a flavor cup associated therewith for receiving an infusion flavoring liquid therein. A method of roasting poultry comprising the steps of providing a flavor infusion device, attaching the device to a sidewall of a roasting pan, placing an infusion liquid in the cup, mounting the poultry on the horizontal arm of the device, preferably in a breast-down orientation, and roasting the poultry.

  • Patent number: 8133596
    Abstract: Cookware having improved uniform heat transfer over the entire cross section thereof, the cookware formed from a multi-layered composite metal having a layer of stainless steel roll bonded at or near the core of the composite to act as a thermal barrier and provide more uniform heat distribution on the cook surface. The stainless layer is roll bonded to layers of aluminum which, in turn, is roll bonded to layers of stainless steel or aluminum or copper. The layer of stainless steel adjacent to the cooking range may be a ferromagnetic grade of stainless steel if induction-type heating is desired. The cookware may include a non-stick surface applied thereto.

  • Patent number: 7980171
    Abstract: A cooking or food warming appliance having a heated heat sink plate situated in a vacuum environment within an outer shell. A food vessel intimately engages the heat sink plate along a food contacting surface thereof by virtue of the vacuum. The vacuum eliminates air gaps between the food contacting surface of the food vessel and the heat sink plate so as to provide instantaneous and uniform heating of the food vessel. The vacuum environment also provides thermal insulation for the heat sink plate whereby heat loss by convection is virtually eliminated.
