Publication number: 20080277400Abstract: A heat retaining dish includes a pressure relief mechanism and has a heat retention material capable of being heated by microwave or other thermal radiation in order to maintain any food placed on the dish at an elevated temperature. The heat retention material is capable of accommodating expansion during heating of the device, and when an overpressure condition occurs as a result of inadvertent overheating, the pressure relief mechanism vents the pressure to the ambient environment. The pressure relief mechanism is an integral part of the wall construction of at least one of the portions making up the housing of the device, and deformation due to overpressure directly causes the opening of the pressure relief mechanism as soon as the housing is deformed sufficiently to open a fluid communication path through an aperture in the wall.Type: ApplicationFiled: May 8, 2007Publication date: November 13, 2008Applicant: Sierra Housewares, Inc.Inventors: Thomas J. Welsh, Vangelis Economou

Patent number: 6210032Abstract: A stirring pitcher which is easy to break down for cleaning and which has a uniquely shaped container that has at its bottom a trough with a contour that matches the contour of the stirrer spoon end. The stirrer includes a handle portion that extends above a container cover, and a stirrer portion which extends below the cover. Preferably the stirrer portion is detachable from the handle portion. The stirrer includes a pivot which is transverse to the longitudinal direction of the container trough, so that pivoting of the spoon about the pivot causes the spoon end to sweep the complete volume adjacent the container bottom.Type: GrantFiled: March 23, 2000Date of Patent: April 3, 2001Assignee: Sierra Housewares, Inc.Inventor: David J.
