Abstract:

An inexpensive portable food container capable of keeping food cold and fresh for several hours. The apparatus comprises two parts: a main compartment consisting of rigid sidewalls and a bottom, and a cover removable from said main compartment, wherein said sidewalls, said bottom and said cover contain a refrigerant substance that remains cold for several hours. The apparatus is designated to be placed inside a fridge (or any similar device) until the refrigerant substance gets cold or frozen. Afterwards, users can place food inside the main compartment, close it with the cover and carry the apparatus with them for later consumption of fresh food. The apparatus can be carried inside a handbag, briefcase, backpack, or any similar device.

Description

The present invention relates to a portable food container capable of keeping the food cold and fresh for several hours. The apparatus can be easily carried in a handbag, briefcase, backpack, or any similar device, for later consumption of the food.

The invention will be better understood after a study of the following detailed description. Such description makes reference to the annexed drawing, wherein:

FIG. 1 is a side perspective view of the portable apparatus according to the present invention.

FIG. 2 is a cross sectional view of the portable apparatus shown in FIG. 1.

The operation of the portable apparatus will be described. A numeral 1 designates the cover of the apparatus: a cover removable from the main compartment. The cover keeps the main compartment sealed when closed, and can be removed to put in or take out food. The cover is filled with a refrigerant substance that remains cold for several hours after being kept at low temperatures.

A numeral 2 designates the main compartment of the apparatus: a container designed to place food inside it. The upper part of the main compartment can be closed with the removable cover designated with numeral 1 and described above. The sidewalls and bottom of the said main compartment are filled with a refrigerant substance that remains cold for several hours after being kept at low temperatures.

A numeral 3 designates the refrigerant substance (that remains cold for several hours after being kept at low temperatures) filling the cover of the apparatus.

A numeral 4 designates the refrigerant substance (that remains cold for several hours after being kept at low temperatures) filling the sidewalls and the bottom of the main compartment.

The apparatus is designated to be placed inside a fridge (or similar device) until the refrigerant substance gets cold or frozen. Afterwards, the user can place food inside the main compartment (designated with numeral 2), close it with the cover (designated with numeral 1) and carry the apparatus with him/her for later consumption of fresh food. The apparatus will keep the food cold and fresh for several hours.

Claims

1. The present invention generally relates to portable food containers, specifically to an inexpensive portable food container capable of keeping food cold and fresh for several hours. The apparatus can be easily carried in a handbag, briefcase, backpack, or my similar device, for later consumption of the food.
