Patent Images
1. A rigid container for containing liquid contents during lyophilization thereof and for retaining the resulting lyophilized product therein under subatmospheric pressure subsequent to lyophilization, said container comprising:
- a lower container body comprising a lower wall in a continuous peripheral side wall;
containing means located adjacent to the upper edge of said side wall and exterior to said container body, said container means accommodating a deformable porous spacer and a rigid cover for said container body, said rigid cover adapted with means to slidably attach to said upper edge and seal said container;
wherein the upper surface of said spacer is in contact with said cover in a manner to retain said cover above said container body whereby exertion of a sufficient downward force upon said cover compresses said spacer and allows said cover to securely attach to said upper edge and seal said container, whereby said compressed spacer is prevented from contact with the contents within the sealed container; and
at least one sealable port in said cover or in said lower container body.
