Abstract
A paint or similar can adapted to retain its lid in fluid tight condition against mechanical or pressure disturbances. The can has a ring element secured to the top of its sidewall and a lid assembled onto the ring element. Rubber or other sealant can be disposed between the ring element and lid to form one or more continuous seals between the ring element and lid. A metallic overcap having a debossment is placed over the lid. Stretchable adhesive tape is adherently applied to the overcap and the sidewall to hold the overcap down tightly against the lid with the debossment pressing against the lid to prevent the lid from backing off from the ring element and breaking the seal. The overcap has a circular central opening to uncover most of the top portion of said lid to allow the top portion of said lid to swell upwardly upon an increase of pressure within the can without dislodging the overcap. The debossment is at an intermediate position between the central opening and the outer periphery of the overcap.
