Welcome to my site.
This project was developed by a former Engineer and now a patent agent assistant studding towards LLM degree. Seeing new inventions is very interesting to me. I created this site to outlines my favorite inventions along with inventions that I believe have potential.

Pizza carrier

by Sutton, Bernard;



The invention relates to hot food carriers in general and in particular to a hot food carrier for pizza and other so-called "take out" foods which it is desirable to maintain hot until they are consumed. A carrier of this kind must be capable of maintaining food at substantially its preparation temperature for as long as possible and must protect the food from damage while it is being carried.

Accordingly it is the object of the invention to provide a food carrier which will maintain the heat of pizza or other hot foods for a substantial period of time until these are ready to be consumed.

Another object of the invention is to provide a carrier of such character which is provided with insulating means for maintaining the heat within the carrier.

A further object of the invention is provide a food carrier which sturdy, light weight and simple in construction, efficient in operation and economical to manufacture.

The foregoing objects will become apparent from the following description and accompanying drawing.

Referring now to the drawing in detail, the pizza carrier shown in FIG. 1 comprises a tray cover having an outer front wall 4, a rear wall 5 a top wall and side walls. The tray cover is formed with inner walls forming an enclosed chamber filled with heat insulating material. The rear wall of the cover is provided with a pair of hooks 10, 12 which are engageable with cleats 14, 16 on rear wall 17 of tray 18 which receives a pizza or similar 4 or another heated food desired to be kept warm. The tray 18 is formed with an outer bottom wall 20 and an inner bottom wall 22. A layer of heat insulating material known in the art to interposed between the two bottom walls. The bottom wall 22 is formed with upwardly extending spacers 26 which serve to support a pizza or other food article carrier in carrier 2. The front wall 28 of the tray has a cut out portion 3 for conveniently grasping the pizza when removing it from the tray. As shown in FIG. 3, there are provided a pair of batches for securing removably the tray cover 2 to the tray 18.

The latches consist of leaf springs 34, 36 secured to outer front wall 4 of the cover and an inner wall 5 by a rivet 38. Secured to each free end of leaf springs 34, 36 is a pin 40 which is adapted to enter holes 40, 42 under the bias of leaf springs 34, 36 respectively.

A carrying handle 46 is provided for the pizza carrier. The carrying handle consists of an "H"-shaped piece of flexible plastic material. The free ends of the handle can be readily inserted in or removed from brackets 50 by contracting the ends to the position illustrated by dotted lines in FIG. 6.
