Abstract: Medical waste, i.e., infectious material such as needles and sharps, are contained in a system that meets Federal Regulations concerning the storage and disposal of medical waste, while also meeting Federal Regulations concerning transportation of such medical waste, yet also is environmental friendly upon disposal. The system includes a one-piece, monolithic plastic bottle contained in a unitary metal outer container, with a one-way plug located in a neck of the bottle to permit items to enter the bottle but to prevent those items from leaving the bottle via the neck. A closure is attached to the neck, with a lid and an overcap ring covering the closed bottle for shipping. Adhesive material can be used to further seal the system, with the container being placed in a corrugated carton that is then sealed with further adhesive for transportation.

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.
