Abstract
Abstract Container for the transport and consumption of pizza and food in general, consisting of a cover equipped with a small peripheral step (5) of same cover under the upper level (7) of the rim (8); this step is interrupted at constant angular intervals by niches (9) tapered towards the bottom, which end at the bottom of the container; these niches are intercalated with analogous niches (14) of inferior depth compared to that of the niches (9), limited by the level (13) and of such dimensions that they consent the outer walls of the niches (9) to fit into the inner part of the niches (14): the step (5) and the niches (9, 14) are protruding towards the outside compared with the walls (4) of the cover. Once arranged the food at the inside of the container, it is possible to place a lid (17) on it, the projections (18) of which come to lean on the bottom levels (13) of the niches (14), or it is possible to place another container on it, resting the bottom of the niches (9) on the levels (13) a.s.o. When empty, the containers fit closely into each other with a minimum of encumberment as to height, as their niches (9) are in correspondence.

Claim 1
Independent Claim
248 words
Container for the transport or storage of food, comprising: a side wall shaped as a truncated cone or truncated pyramid with any chosen number of sides, growing narrower towards the bottom; a bottom wall connected to the lower end of said side wall; and a projecting upper grip and stiffener rim extending from the top of said side wall, said rim having a peripheral edge; wherein said side wall includes: a small peripheral step therein below and inside of the upper level of said peripheral rim, said peripheral step protruding to the outside compared to the portion of said side wall therebelow; a plurality of first niches therein interrupting said peripheral step at intervals of constant width, which first niches grow narrower towards the bottom, the walls of said first niches originating at the upper level of said rim and extending to said bottom wall, said first niche-walls projecting towards the outside compared to the portion of said side wall below said peripheral step; and a plurality of second niches therein, each said second niche being disposed at half the interval between successive ones of said first niches, the walls of each said niche originating at the level of said peripheral step and extending to a level above said bottom, wherein said second niches grow narrower toward the bottom and have a floor closing the bottom thereof, the level of said floor being at or above the level of the food anticipated to be carried by the container.
Claim 2
Dependent Claim
248 words
Container for the transport or storage of food, comprising: a side wall shaped as a truncated cone or truncated pyramid with any chosen number of sides, growing narrower towards the bottom; a bottom wall connected to the lower end of said side wall; and a projecting upper grip and stiffener rim extending from the top of said side wall, said rim having a peripheral edge; wherein said side wall includes: a small peripheral step therein below and inside of the upper level of said peripheral rim, said peripheral step protruding to the outside compared to the portion of said side wall therebelow; a plurality of first niches therein interrupting said peripheral step at intervals of constant width, which first niches grow narrower towards the bottom, the walls of said first niches originating at the upper level of said rim and extending to said bottom wall, said first niche-walls projecting towards the outside compared to the portion of said side wall below said peripheral step; and a plurality of second niches therein, each said second niche being disposed at half the interval between successive ones of said first niches, the walls of each said niche originating at the level of said peripheral step and extending to a level above said bottom, wherein said second niches grow narrower toward the bottom and have a floor closing the bottom thereof, the level of said floor being at or above the level of the food anticipated to be carried by the container.
