Abstract
Abstract A novel food container for the storage and transport of food, particularly hot food such as pizza. The container comprises an identical upper and lower portion, each portion having a flat, base surface, outwardly extending side walls with a circumferential lip therearound. A locking means is carried on the lip to releasably lock the upper and lower portions together. A plurality of vertical honeycombs are on the interior of the base surface and a plurality of buttresses are found in the interior side walls. The device is preferably made of an expanded material such as polystyrene and only requires an single mould to manufacture it.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
199 words
An insulated, hermetically-sealable, thin-walled food container for the storage and transport of food, comprising: (a) an upper portion and a lower portion, said upper and said lower portions being identical, each said portion comprising: (i) a thin-walled flat base surface, (ii) thin, outwardly-extending side walls, and (iii) a circumferential lip around the top of said side walls; (b) locking means adapted to releasably and hermetically lock said upper and lower portions together, (c) a plurality of elongate wall members integral with and upstanding from the interior surface of said base surface, each of said plurality of wall members being integrally joined at each end thereof to two others of said wall members to define a regular pattern of hexagonally-shaped recesses upstanding from said base surface, except for said wall members immediately adjacent said side wall which are joined to each other at each end and from the outer perimeter of said regular pattern of recesses, and (d) a plurality of vertical elongate parallel ribs integral with and extending from the interior of each side wall to impart strength thereto, said ribs extending downwardly into integral join with the integrally-joined ends of said perimeter-forming wall members adjacent said side walls.
Claim 2
Dependent Claim
199 words
An insulated, hermetically-sealable, thin-walled food container for the storage and transport of food, comprising: (a) an upper portion and a lower portion, said upper and said lower portions being identical, each said portion comprising: (i) a thin-walled flat base surface, (ii) thin, outwardly-extending side walls, and (iii) a circumferential lip around the top of said side walls; (b) locking means adapted to releasably and hermetically lock said upper and lower portions together, (c) a plurality of elongate wall members integral with and upstanding from the interior surface of said base surface, each of said plurality of wall members being integrally joined at each end thereof to two others of said wall members to define a regular pattern of hexagonally-shaped recesses upstanding from said base surface, except for said wall members immediately adjacent said side wall which are joined to each other at each end and from the outer perimeter of said regular pattern of recesses, and (d) a plurality of vertical elongate parallel ribs integral with and extending from the interior of each side wall to impart strength thereto, said ribs extending downwardly into integral join with the integrally-joined ends of said perimeter-forming wall members adjacent said side walls.

Claim 8
Dependent Claim
246 words
A polystyrene insulated hermetically-sealable, thin-walled food container for the storage and transport of food, comprising: (a) an upper portion and a lower portion, said upper and said lower portions being identical, each said portion comprising: (i) a thin-walled flat base surface, (ii) thin outwardly-extending side walls, and (iii) a circumferential lip around the top of said side walls; (b) locking means adapted to releasably and hermetically lock said upper and said lower portions together, said locking means comprising a protrusion extending upwardly from the top surface of said lip about one-half the circumference of said lip and a complementary recessed portion in the remaining one-half portion of the circumference of said lip; (c) a plurality of elongate wall members integral with and upstanding from the interior surface of said base surface, each of said plurality of wall members being integrally joined at each end thereof to two others of said wall members to define a regular pattern of hexagonally-shaped recesses upstanding from said base surface, except for said wall members immediately adjacent said side wall which are joined to each other at each end and form the outer perimeter of said regular pattern of recesses, and (d) a plurality of vertical elongate parallel ribs integral with and extending from the interior of each side wall to impart strength thereto, each rib extending the height of the side wall and downwardly into integral join with the integrally-joined ends of said perimeter-forming wall members adjacent said side walls.
Claim 9
Dependent Claim
246 words
A polystyrene insulated hermetically-sealable, thin-walled food container for the storage and transport of food, comprising: (a) an upper portion and a lower portion, said upper and said lower portions being identical, each said portion comprising: (i) a thin-walled flat base surface, (ii) thin outwardly-extending side walls, and (iii) a circumferential lip around the top of said side walls; (b) locking means adapted to releasably and hermetically lock said upper and said lower portions together, said locking means comprising a protrusion extending upwardly from the top surface of said lip about one-half the circumference of said lip and a complementary recessed portion in the remaining one-half portion of the circumference of said lip; (c) a plurality of elongate wall members integral with and upstanding from the interior surface of said base surface, each of said plurality of wall members being integrally joined at each end thereof to two others of said wall members to define a regular pattern of hexagonally-shaped recesses upstanding from said base surface, except for said wall members immediately adjacent said side wall which are joined to each other at each end and form the outer perimeter of said regular pattern of recesses, and (d) a plurality of vertical elongate parallel ribs integral with and extending from the interior of each side wall to impart strength thereto, each rib extending the height of the side wall and downwardly into integral join with the integrally-joined ends of said perimeter-forming wall members adjacent said side walls.
