Abstract
A food service container is provided comprising a rimmed receptacle and a lockable paperboard lid. The lid consists of a cover panel with a pair of extension tabs formed at opposed edges of the cover panel, and a locking assembly depending from each extension tab. Each locking assembly comprises an outer wall panel foldably connected to the extension tab and depending downwardly therefrom, means in each outer wall panel defining a semi-detachable retaining tongue, a bottom wall panel foldably connected to the outer wall panel and extending inwardly therefrom, an inner wall panel foldably connected to the inner wall panel and secured in underlying relation to each extension tab, and an engagement slot formed at the junction of inner wall panel and the glue flap. The lid is locked to the receptacle by engaging the rim of the receptacle in the two slots, and detaching the retaining tongues from the outer wall panels to engage the portions of the rim protruding through the slots so that the retaining tongues exert outward and upward biases on the rim.
