Container with improved retention properties and improved corner structures

A shallow container formed from a unitary, prescored blank and comprising:

• a bottom panel
• a top panel,
• a first side wall hingedly connecting said top and bottom panels, said side wall having first and second ends,
• second third outer side walls connected to and depending from one of said bottom and top panels,
• second and third inner side walls connected to and depending from the other of said bottom and top panels,
• at least one fourth side wall connected to and depending from one of said top and bottom panels and closure means connected thereto for selectively maintaining said top panel in a closed position,
• first and second pairs of inner and outer rear diagonal side wall panels connected to said second inner and outer side walls and said third inner and outer side walls, respectively,
• first and second pairs of inner and outer coupling panels connecting each of said first and second pairs of inner and outer rear diagonal wall panels to said top and bottom panels, and
• first and second set-up panels connected, respectively, to said first and second ends of said first side wall, said first and second set-up panels also being connected, respectively, to said first and second pairs of inner and outer coupling panels.

• second and third outer side wall means connected to and depending from one of said bottom and top panels and
• second and third inner side wall means connected to and depending from the other of said bottom and top panels, said second and third inner and outer side wall means defining at least one channel therebetween,
• a fourth side wall connected to and depending from one of said top and bottom panels and closure means connected thereto for selectively maintaining said top panel in a closed position,
• first vent means defining an inlet through which warm air from the inside of the container can enter said at least one channel, and
• second vent means spaced from said first vent means and defining an outlet through which warm air can exit said at least one channel,
• wherein, warm air entering said at least one channel from inside the container raises the temperature within said at least one channel, so as to reduce the rate at which heat is transferred through said inner side wall means from the interior of the container.

A shallow container for hot food products such as pizza pies, said container comprising

• a bottom panel having an inside surface and an outside surface,
• a top panel having an inside and an outside surface,
• a rear wall hingedly connecting said top and bottom panels,
• two opposed side walls having inside and outside surfaces, said side walls being connected to said top or bottom panel,
• a front wall connected to said top or bottom panel,
• a sheet of foil material having first and second opposed major surfaces, said first major surface being bonded to and covering substantially all of the inside surface of said bottom panel, in face-to-face relationship therewith, said inside surface of said top panel being substantially free of foil material, and
• depressions provided in said sheet of foil material for releasing moist air from between said second opposed major surface of said sheet of foil material and a hot food product carried thereon.
