Abstract

A plastic container with an inverted V-shaped rim at the upper edge of its body. The rim configuration makes it easy to pour contents from the container and, after pouring, any material remaining on the rim will slide off. A cover with a V-shaped flange mates with the rim which holds it out of contact with the inner and outer surface of the body wall. The cover also has a pocket containing a sealing ring which is passed against the rim by a locking strap to seal the container.
