Abstract
A package containing a particulate product under pressure which automatically releases the pressure upon opening with an ordinary can opener, while preventing escape of the particulate material. The package is made up of a container having a closed top and a closed bottom which are connected to a body portion to define a gas tight interior compartment. The container has an inwardly directed bead along the perimeter of the body of the container located at a predetermined distance from the top. A non-porous product separator is placed within the container above the bead so that its perimeter is adjacent to the perimeter of the body of the container. The separator divides the interior compartment into a product chamber, below the separator, and a product free chamber above the separator. The distance from the bead to the top of the container is such that rocking of the separator with respect to the vertical axis of the container is prevented to the extent that the particulate product is prevented from migrating around the separator and into the product-free chamber before and during opening.
