Dual compartment sandwich package

A dual compartment foam package having a pair of adjacent complementary food portion holding chambers for the open-face halves of a sandwich, including a hot meat product and cool trimmings, such as lettuce and tomato and the like, comprising:

• a foam base having two integrally formed compartments in substantially planar side-by-side longitudinal relationship;
• a foam cover having a pair of integrally formed domes in substantially planar side-by-side longitudinal relationship for covering said base;
• one said dome being coextensive with one said compartment to define a first chamber, the other said dome being coextensive with said other compartment to define a second chamber;
• cooperating latching means on said base and on said cover for releasably securing together said base and cover in chamber-forming array;
• insulating means forming an external seal for insulating the hot meat product and cool trimmings from the ambient atmosphere
• base reinforcing and barrier means including
• a transversely extending bi-ended rib located between the base compartments and having a pre-determined upper surface profile extending above the adjacent compartments,
• the ends of the rib being transversely spaced apart from the insulating means to define recesses
• and cover reinforcing and barrier means including a transversly extending bi-ended rib located between but spaced apart from the cover domes and having an open lower surface profile adapted to mate with the base transverse rib with surface-to-surface contact,
• the cover end reinforcing barrier means further including a plurality of reinforcing struts, each strut extending longitudnally between the cover domes and joining an end of the cover rib to form an H-patterned reinforcement structure between the domes to rigidify the closed package so as to resist package bending along the longitudinal and transverse axes.

A foam sandwich package comprising a pair of adjacent chambers for holding complementary food portions, each chamber comprising a coextensive compartment and dome,

• a first package portion having two integrally formed open-topped compartments in substantially planar side-by-side longitudinal relationship, each of said compartments comprising a bottom wall, an upwardly tapering end wall, and a pair of side walls;
• a second package portion having a pair of integrally formed domes in substantially planar side-by-side longitudinal relationship for covering said first package portion, each of said domes comprising a top wall, a downwardly tapering end wall, and a pair of side walls,
• cooperating latching means on said first and on second package portions of releasably securing together said package portions in chamber-forming array;
• base reinforcing and barrier means including
• a transversely extending bi-ended rib located between the base compartments and having a predetermined upper surface profile extending above the adjacent compartments,
• and cover reinforcing and barrier means including a transversly extending bit-ended rib located between but spaced apart from the cover domes and having an open lower surface profile adapted to mate with the base transverse rib with surface-to-surface contact,
• the cover and reinforcing barrier means further including a plurality of reinforcing struts, each strut extending longitudinally between the cover domes and joining an end of the cover rib to form an H-patterned reinforcement structure between the domes to rigidify the closed package so as to resist package bending along the longitudinal and transverse axes.
