| 20110062157 | SYSTEM FOR PRESSURE RELEASE FROM A CLOSED CONTAINER AND A CONTAINER FOR USE THEREFORE - The invention is a safety device, and a container utilizing such a device, for release of pressure from a closed container, when the container is heated. The container has a ventilation opening, sealed by a disk which is made to melt at a critical temperature. The disk is manufactured from a plastic and has at least one recess in the area of the ventilation opening. The ventilation opening is situated at one end of a ventilation pipe, wherein the pipe is at least partially overlapped by the affixing device and detachably connected to it. The ventilation pipe has an exterior threading located at the end of the pipe overlapped by the affixing device. The detachable connection can be made by screwing the sleeve nut onto the exterior threading. The disk has a design of varied geometry embedded therein; the design creating varying surface thicknesses for the disk, which allow the disk to melt at varying rates depending upon the temperature of the interior of the container. | 03-17-2011 |
