  • Patent number: 10717252
    Abstract: Provided is an article of cookware and a method of making the same. The cookware has a multi-layer bonded composite wall structure having an inner metal layer and an outer metal layer, and a core layer between the inner layer and the outer layer. The core layer has at least two perforated graphite plates, each plate having a plurality of spaced-apart holes formed therethrough, and at least one intermediate metal element disposed between the at least two perforated graphite plates and extending through the plurality of spaced-apart holes of each of the at least two perforated graphite plates. The at least one intermediate metal element is metallurgically bonded to the inner layer and the outer layer at least through the plurality of spaced-apart holes.

  • Patent number: 10478012
    Abstract: A method of making cookware containing a bonded composite comprising the steps of providing at least two layers of materials by pressurizing and heating 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. The method also includes providing a plurality of sets of bonding blank assemblies by solid state processing under pressure and heat.

  • Patent number: 9756979
    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: 9144349
    Abstract: A pot rack comprising at least one track member having spaced-apart rails with at least an upper rail surface having a ferromagnetic property and at least one hook member having a lower hook portion for releasably engaging a kitchen utensil, and an upper cap portion of a dimension greater than a spacing between the rails wherein the cap portion includes a magnetic member which is magnetically attracted to the upper rail surface of each of the rails and a shank portion interconnecting the upper cap portion and the lower hook portion. A hook member for use on a slotted ferromagnetic rail comprising a head portion, an integral shank portion and a hook portion extending from the shank portion, said head portion having magnetic means associated therewith to establish a magnetic attraction between the head portion and the rail.
