Benefits of technology

[0010]An aspect of the present invention is to provide a simpler and more cost-effective device for pressure release of closed containers when heated.

Problems solved by technology

When the container is heated, the pressure rises, which, upon reaching a pressure limit value and thus a limit temperature, could cause the container to burst and the container's contents to come out in uncontrolled fashion.

Abstract

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.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority from German Patent Application Serial No. 20 2009 012 542.4, filed Sep. 17, 2009, the entire contents of which is herein incorporated fully by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a safety device for releasing pressure from closed containers when heated. More specifically, the present invention relates to a disk or plate for covering the opening of a container, wherein the disk or plate dissolves at a particular temperature threshold so as to release pressure within the container when heated.[0004]2. Description of the Related Art[0005]When fluids are transported in closed containers, considerable pressure can build up in the interior of the containers, particularly if the container is heated; this can ultimately cause the container to burst. For this reason, for example, in trade-law regulations with regard to construction of metallic i...
