  • Patent number: 5064055
    Abstract: A cooking utensil for use on both gas, electric and induction stoves is provided composed of a container liner of stainless steel with a comparatively low wall thickness, a comparatively thick bottom plate of aluminum or a metal of similarly good heat-conducting properties and a bottom disc that is at least partially composed of magnetizable material disposed on the outside of the bottom plate. The bottom plate disposed on the outside bottom of the container and possibly the bottom disc disposed on the outside of the bottom plate can be attached by a commonly known hammer-press technique at an increased temperature preferably with an intermediate foil of aluminum or a material of similarly good heat-conducting properties. Particularly favorable results for cookware in terms of expansion reaction and corrosion have been achieved utilizing a bottom disc of a nickel alloy having the following composition: Ni: 50-100%; Cr: up to 6%; Mo: up to 6%; Cu: up to 14%; Mn: up to 6%; Si: up to 1.5%; C: up to 0.

  • Patent number: 5012951
    Abstract: A hopper for use with a hollow cylindrical container open at one end. The open container end has an exposed edge. The hopper comprises a plurality of at least two partial hoppers, the partial hoppers extending generally at right angles to the axis of the container and being disposed one below the other. All partial hoppers are secured together, each partial hopper having an outer periphery of the same shape as the periphery of the open container end. At least the uppermost partial hopper has its peripheral edge secured to the exposed edge of the open container end. All partial hoppers have a common opening spaced inwardly from the peripheries of the partial hoppers and have a common center aligned with the axis of the container.

  • Patent number: 4998638
    Abstract: A can has a film which is stretched on the inside of an end plate thereof so as to be deflectable in and out of contact with the end plate so that the can which has heated contents packed and sealed therein can be prevented from deformation caused as the contents cool down. The above-mentioned can is manufactured by overlaying the end plate and the film one on top of the other and then unitarily securing the end brim of the can body and the peripheral edge portion of the end plate to each other by double seaming, with the film disposed on the inside of the end plate.
