Abstract

A container is formed of a generally bowl-shaped receptacle which is open at the top. The bottom of the receptacle is provided with a depending shoulder having a recess in the inner surface thereof. A base is secured to the receptacle by means of locking arms which engage the recess in the shoulder. The top portion of the base is sufficiently flexible to permit the two sections of the container to be snapped together when assembled.

A container suitable for use in packaging foodstuffs and the like comprising a generally bowl-shaped receptacle open at the top, the bottom of said receptacle being provided with a circumferential depending shoulder the inner surface of which is provided with a continuous circumferential recess, the portion of said inner surface below said recess being convex in radiant cross section and the portion of said inner surface above said recess being concave in radial cross section and a base secured to said receptacle, the top of said base being provided with a plurality of raised radially extending locking arms, the outer surfaces of which are of substantially the same configuration as the inner surface of said shoulder the top portion of said base being sufficiently flexible to cause the outer surfaces of said projections to mate with the inner surface of said shoulder and be locked therewith when the container is assembled by said base being positioned adjacent said receptacle and a force being applied to the central region of said base in a direction toward said receptacle.

2. The container of claim 1 in which said base is of generally bowl-shaped configuration and is inverted relative to said receptacle, said base being of smaller size than said receptacle to form a compote dish.
