Abstract

A container cover locking assembly comprises 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 which depend downwardly from the ridge, extend along a substantial portion thereof and curve outwardly toward yet terminate skirt of the skirt. The locking assembly allows a simplified molding process for a container cover which is assembled with a container body of the type having curved mounting seat formed from the upper edge of the container walls.

Claims

1. A locking assembly for a container cover used with a container body of the type having a cover seat formed from the inwardly curved upper edges of the container body'"'"'s side panels, comprising:

a base member;

a continuous peripheral skirt depending downwardly from said base member;

a ridge depending downwardly from said base member, said ridge being spaced inwardly from and parallel with said skirt and forming together with said skirt and the portion of said base member between said skirt and said ridge a mounting channel which engages said container mounting seat; and

several tapered locking lips depending from said ridge and curving outwardly toward yet terminating short of said skirt for urging said container cover down against said mounting channel.

2. The device of claim 1 wherein the container cover is integrally molded from a resinous material.

3. The container cover of claim 1 wherein the peripheral skirt depends downwardly below the terminal portion of the locking lip.

4. The locking means of claim 1 wherein the tapered locking lip terminates in a bevelled edge which urges said lip away from the skirt during the installation of the cover onto the container body mounting seat.

5. The device of claims 1 or 4 wherein the container cover is rectangular and the locking lips laterally extend for a substantial portion along each edge of said cover.

6. The device of claims 1 or 4 wherein the container cover is circular and includes a plurality of arcual locking lips.

7. The device of claims 1 or 4 wherein the tapered locking lips extend downwardly below the terminal edge of the cover seat.
