Abstract
An improved container cover locking assembly has a base member with a continuous peripheral skirt depending therefrom and a ridge parallel to yet spaced inwardly from the skirt along the underside of the base member. Tapered locking lips depend downwardly from the ridge, extend along a substantial portion thereof and curve outwardly toward, yet terminate short of, the skirt. At least one support rib is vertically disposed along each of the locking lips to stiffen the lips in the normal locking position. The locking assembly allows a simplified molding process for a container cover which is assembled with a container body of the type having a curved mounted seat formed from the upper edge of the containers's walls.
