Claim 2

In combination, a container and a cover for the container, said container comprising: a bottom, a connected sidewall, said sidewall having an upper edge, an outwardly extending element on said edge, a downward extension on said outwardly extending element, said extension being spaced from the sidewall, an outwardly extending footlike member on the extension and an outstanding abutment at the junction of the outstanding element and the extension; said cover comprising a main body member having an upwardly extending element adjacent the periphery thereof, an outwardly extending element on the upwardly extending element and a downward extension at the terminal edge of the outwardly extending element, an inwardly extending projection at the inner aspect of said extension adapted to snap in under the abutment on the container with the outwardly extending element of the cover in substantial contact with the outwardly extending element at the edge of the container.

Claim 3

In combination, a container and a resilient cover for the container, said container comprising: a bottom, a sidewall connected thereto, said sidewall having an upper edge, a multiple flange at said upper edge including an outstanding member, a downward extension thereon spaced from the sidewall, a terminal outstanding member on the lower edge of the downward extension, and an outwardly extending abutment at the juncture of the outstanding member and the extension; said cover comprising a main body portion for disposition in the container at the upper edge thereof, and a multiple flange on the main body portion at the periphery thereof; said cover flange comprising a U-shaped trough having an outer and an inner wall, an outstanding member on the outer wall of the U-shaped member, a downturned extension at the periphery of the cover outstanding member, and an inwardly projecting rim on the downturned extension, constructed and arranged to latch under the abutment but being resilient enough to be capable of manual release therefrom to remove the cover.

Claim 4

In combination, a container and a resilient cover for the container, said container comprising: a bottom, a sidewall connected thereto, said sidewall having an upper edge, a multiple flange at said upper edge including an outstanding member, a downward extension thereon spaced from the sidewall, a terminal outstanding member on the lower edge of the downward extension, and an outwardly extending abutment at the juncture of the outstanding member and the extension; said cover comprising a main body portion for disposition in the container at the upper edge thereof, and a multiple flange on the main body portion at the periphery thereof; said cover flange comprising a U-shaped trough having an outer and an inner wall, an outstanding member on the outer wall of the U-shaped member, a downturned extension at the periphery of the cover outstanding member, and an inwardly projecting rim on the downturned extension, constructed and arranged to latch under the abutment but being resilient enough to be capable of manual release therefrom to remove the cover.

Claim 5

The combination of claim 1 wherein the container terminal outstanding member underlies the inwardly projecting rim.

Claim 6

The combination of claim 1 wherein the container terminal outstanding member underlies the inwardly projecting rim in spaced relation thereto.

Claim 7

The combination of claim 1 wherein the container terminal outstanding member underlies the inwardly projecting rim and extends outwardly at least as far as the edge of the cover downturned extension.

Claim 8

The combination of claim 1 including a bead on the sidewall of the container in position to impinge upon the outer wall of the U-shaped trough of the cover.
