Patent abstract
The present invention creates a new rigid degassing valve. The valve of the present invention utilizes a relatively stiff support body in order to successfully vent gases, such as carbon dioxide, from within the packaging. Carbon dioxide may be created by organic products placed in the packaging which causes the package to expand. The valve of the current invention maintains its shape as the package becomes bloated and takes on a rounded shape due to carbon dioxide expended by the roasted coffee beans.
