Patent number: 5386921Abstract: A metal utensil with handles shaped onto the marginal portions thereof can be manufactured in a simple, material-saving manner. Such a utensil can be used in a more universal manner than conventional utensils. A utensil usable as either a container part (10) and/or a lid part (15), has handles (4) for holding the utensil with a handle attachment (12) shaped onto the rim of the opening to which a handle is connected.Type: GrantFiled: February 7, 1994Date of Patent: February 7, 1995Assignee: Heinrich Kuhn Metallwarenfabrik AGInventor: Jacques Kuhn

Patent number: 5307951Abstract: The invention shows how a metal utensil with handles shaped onto the marginal portions thereof can be manufactured in a simple, material-saving manner. Such a utensil can be used in a more universal manner than conventional utensils.The metal utensil comprising the container part (10) and/or the lid part (15), with handles (4) for holding the utensil, is characterized in that the handle parts have at least one handle attachment (12) for fixing a handle (4) shaped onto the rim of the opening.As a result of the special shaping of the handle attachments a system utensil is obtained, with e.g. significantly improved stackability, reciprocal usability, e.g. bain marie cooking and more extensive uses, e.g. as a pouring, steaming or sieving vessel. Through shaping and the use of heat distributing laminated materials a local overheating in the vessel is virtually impossible and a uniform heat distribution over the entire vessel surface is ensured. The handle attachments 12, e.g.Type: GrantFiled: March 30, 1992Date of Patent: May 3, 1994Assignee: Heinrich Kuhn Metallwarenfabrik AGInventor: Jacques Kuhn

Patent number: 5135128Abstract: A water kettle is equipped with a handle, a first end of which is joined to lower regions of the side of the kettle by a hinge, and a second end of which is fitted on the diametrically opposite side with a spout lid for covering (and opening) the kettle's spout. When the kettle is in the rest position, as a result of its weight the handle will drop until the handle comes to stop on the spout and the spout lid covers the spout opening. When the kettle is lifted by the handle or tipped into the pouring position, the handle swings back to a stop in the spout and the associated spout lid is removed from the spout opening. Following this swiveling movement, the raised spout lid is brought into a position which deflects steam flowing out of the spout opening in such a way that a user's hand holding the handle is not directly exposed to the steam. The spout lid is provided with a device for emitting an acoustic signal when the boiling point is reached in the interior of the kettle.Type: GrantFiled: October 20, 1990Date of Patent: August 4, 1992Assignee: Heinrich Kuhn Metallwarenfabrik AGInventor: Jacques Kuhn

Patent number: 4790292Abstract: A cooking vessel suitable for use with induction plates as well as with conventional electric cooking plates, ceramic hobs or gas cookers has an inner wall, an outer wall, and a thermally conductive plate arranged along the bottom of the vessel and between the inner and outer walls. The outer wall is formed of a composite material having an outer layer of a rust-proof material, a middle layer of a ferromagnetic material, and an inner layer of a rust-proof material. The inner wall is connected to the outer wall in a gas-tight manner along the rim of the vessel.Type: GrantFiled: October 27, 1986Date of Patent: December 13, 1988Assignee: Heinrich Kuhn Metallwarenfabrik AGInventor: Jacques Kuhn
