A foam sandwich package having a dish section and a cover section and a latching mechanism comprising a forwardly projecting latching tongue extending into a latching aperture. The tongue is biased forwardly by the dish section and the aperture is formed in the cover portion. The dish section may be hingedly connected to the cover section, and score lines in the hinge section may be so arranged that they assist in maintaining a bias of the latching tongue forwardly.

A foam sandwich package comprising: a lower dish section and an upper cover section for covering said dish section, said dish section comprising a supporting floor and an upstanding peripheral side wall extending upwardly and outwardly from the floor to an upper peripheral wall edge, said floor being proportioned to support said dish section on a table surface, said cover section comprising a dome and a peripheral side wall extending downwardly and outwardly from said dome to a lower peripheral wall edge, said dome being proportioned to support said cover section on a table surface, said cover section defining a depending peripheral skirt circumscribing the major portion of said lower peripheral wall edge and which skirt, when said cover section is juxtaposed with said dish section, embraces and circumscribes a major poRtion of said upper peripheral wall edge, a latching mechanism for said dish and cover sections comprising at least one rigid latching tongue, said tongue laterally extending from said dish section at a front portion of said dish side wall, said latching tongue projecting forwardly of said front wall portion and lying in a plane substantially parallel to the plane of a table surface when said dish section is supported on a table surface, and said latching mechanism further comprising a complementary latching aperture defined in the side wall of said cover section for each said latching tongue, each said latching aperture opening laterally of the side wall of said cover section and being positioned adjacent said lower peripheral wall edge and having a width at least as great as the width of the latching tongue, a web at the base of the latching aperture and projecting the outwardly of said cover side wall and being proportioned to underlie a latching tongue when said cover and dish sections are juxtaposed and latched, said front wall portion of said dish section including a resilient portion generally beneath said latching mechanism which when pushed inwardly allows the latching tongue to be retracted inwardly of the inner edge of the surfaces defining said latching aperture and then, when released, biases the latching tongue outwardly through the latching aperture, and wherein a said latching tongue, when said cover and dish sections are juxtaposed and latched, projects outwardly beyond the skirt and over a said web, and wherein said lower dish section maintains an outward bias against the upper cover section at the latching mechanism, thereby to help maintain the latching mechanism in a latched condition and to help prevent accidental opening of the package, and in which said latching tongue and said front wall portion merge in a reinforcing strut.
