US4360118A — Self-mating pizza pie container

Claim 1

Independent Claim 294 words

A self-mating pizza pie container comprising, in combination, a pair of identical, circular, lower and upper container half-sections, each having a flat circular body portion and a relatively short rim member defining, together with its body portion, a shallow recess, said rim member, at the inside thereof, defining an obtuse angle with respect to the inside of said circular body portion, the insides of said body portion and said rim having smooth surfaces, each container half-section having, in its peripheral rim member, opposed locating pin and locating recess means for the interfitting reception of the complemental locating pin and locating recess means of the companion half-section for relative rotational locating for closure of said two half-sections, each container half-section further having in its peripheral rim member resilient means adapted to interhookingly engage under rim member edge portions of the companion container half-section upon said half-sections being so relatively located and interfitted for closure, said interhookingly engaging means comprising a first, upwardly-extending, terminal rim portion integrally formed with each of said rim members, and a second downwardly-inclined terminal rim portion integrally formed with each of said rim members, said first terminal rim portions being of such configuration as to overlap in close-fitting nesting relation upon said lower and upper container half-sections being so interfitted for closure, said second terminal rim portions each further comprising a plurality outwardly-extending hook portions defining resilient, inwardly-extending shoulders adapted to interhookingly engage edge portions of the second terminal rim portion of the companion container half-sections upon a pair of said container sections being so interfitted for closure, said first terminal rim portion extending approximately 180 circular degree about its circular body portion, and said second terminal rim portion extending approximately the remaining 180 circular degrees about its circular body portion.

Claim 2

Dependent Claim 294 words

A self-mating pizza pie container comprising, in combination, a pair of identical, circular, lower and upper container half-sections, each having a flat circular body portion and a relatively short rim member defining, together with its body portion, a shallow recess, said rim member, at the inside thereof, defining an obtuse angle with respect to the inside of said circular body portion, the insides of said body portion and said rim having smooth surfaces, each container half-section having, in its peripheral rim member, opposed locating pin and locating recess means for the interfitting reception of the complemental locating pin and locating recess means of the companion half-section for relative rotational locating for closure of said two half-sections, each container half-section further having in its peripheral rim member resilient means adapted to interhookingly engage under rim member edge portions of the companion container half-section upon said half-sections being so relatively located and interfitted for closure, said interhookingly engaging means comprising a first, upwardly-extending, terminal rim portion integrally formed with each of said rim members, and a second downwardly-inclined terminal rim portion integrally formed with each of said rim members, said first terminal rim portions being of such configuration as to overlap in close-fitting nesting relation upon said lower and upper container half-sections being so interfitted for closure, said second terminal rim portions each further comprising a plurality outwardly-extending hook portions defining resilient, inwardly-extending shoulders adapted to interhookingly engage edge portions of the second terminal rim portion of the companion container half-sections upon a pair of said container sections being so interfitted for closure, said first terminal rim portion extending approximately 180 circular degree about its circular body portion, and said second terminal rim portion extending approximately the remaining 180 circular degrees about its circular body portion.

Claim 3

Dependent Claim 75 words

A self-mating pizza pie container as defined in claim 1, wherein said opposed locating pin and locating recess means comprises a locating pin and a complemental locating recess diametrically-opposed to one another in each rim member of each container half-section, the longitudinal axes of which locating pin and recess are perpendicular with respect to the plane of their associated circular body portion, said locating pins extending outwardly of the recesses of their respective container half-sections.

Claim 4

Dependent Claim 29 words

A self-mating pizza pie container as defined in claim 1, wherein said container half-sections are integrally fabricated of a synthetic plastic material having a low coefficient of thermal conductivity.

Claim 5

Dependent Claim 23 words

A self-mating pizza pie container as defined in claim 1, wherein said container half-sections are integrally formed of a foamed synthetic plastic material.

Claim 6

Dependent Claim 26 words

A self-mating pizza pie container as defined in claim 4, wherein the undersides of said container half-sections are integrally formed with a plurality of radially-extending ribs.
