摘要

A plastic container and cover assembly which is opened with mutilation or severing of an outer top peripheral portion of the container, and reclosed with the original cover for reuse; the peripheral portion of the cover is of inverted U-shape providing an inner flange for frictional or snap interlocking with the container body wall and an outer dependent flange extending into an upwardly open groove or trough on the container, the horizontal flange portion of the cover overlying an outward radial rim portion on the container which rim portion is peripherally weakened continuously or at intervals to be severed therealong upon removal of the container grooved portion and cover with discarding of the severed grooved portion and permissive reuse of the cover to close the container, and with the weakened portion severed along at least a substantial portion thereof following any attempt to pry the cover from the container grooved portion, thus indicating a mutilation of that portion of the container as a tell-tale.
