Abstract
A pressure-motion compensating diaphragm for air and liquid tight sealing, in combination with a cap, of a container. The diaphragm has (1) an edge engaging at least one of the cap and the container, and positioning the diaphragm horizontally in the container proximate the neck of the container and under the cap; (2) a center deflector button; and (3) a plurality of silfon tori segments extending from the edge to the center deflector button. The dimensions and geometries of the edge, center deflector button, and tori segments are predetermined to compensate uniquely for forces applied to the diaphragm and created by pressure changes inside and outside the container that occur as the container is filled with a product and processed through filling, pasteurization, or cooling steps. Also provided is an apparatus including the cap, the container, and the diaphragm for releasably storing the product.
