A Safety Cap for the Pressure Release Valve of a Pressure Cooker and a Pressure Cooker Using the Same

摘要

This is a safety cap made of a mesh casing body and attachment frame that covers the pressure release valve of a pressure cooker. The stainless steel wavy mesh has openings of equal size or smaller than the air intake apertures of the pressure release valve. The mesh catches food and prevents the pressure release valve from clogging. There are three main ways to install the safety cap to the pressure cooker: directly attaching it to the pressure release valve via the attachment frame; directly attaching it to the lid; and attaching it to a specialized lid chamber. If the pressure cooker is made of aluminum or other materials, then the safety cap can be snap-fitted or screw-mounted for each installation method. If the pressure cooker is made of carbon core stainless steel, in addition to the snap-fit and screw-mount, it can also be magnetically attached for each installation method.
