Description
BACKGROUND OF THE INVENTION
1. Field of the Invention

The present invention relates to an insulated lunch bag and, more particularly, to an insulated lunch bag that has a compartment specially insulated for keeping food hot and another compartment to keep the food cold.


2. Description of the Related Art

Several designs for lunch bags have been designed in the past. None of them, however, include a plurality of insulated materials for keeping hot or cold the food stored therein.


Applicant believes that a related reference corresponds to U.S. Pat. No. 9,498,036 issued for a carrying kit which is used to maintain foodstuff at a desired temperature which has a divide unit and hot/cold packs. Applicant believes that another related reference corresponds to U.S. Pat. No. 8,573,002 issued for a portable cooler with a plurality of compartments for holding food and drink items while keeping them cold. None of these references, however, teach of a soft sided bag assembly with handles and an insulated internal divider which allows the user to carry both hot and cold food items in separate compartments while still maintaining the temperature of the food items.


Other documents describing the closest subject matter provide for a number of more or less complicated features that fail to solve the problem in an efficient and economical way. None of these patents suggest the novel features of the present invention.


SUMMARY OF THE INVENTION

It is one of the objects of the present invention to provide an insulated lunch bag that includes a handle to easily carry the lunch bag.


It is another object of this invention to provide an insulated lunch bag that includes two compartments which are accessible through a zipper.


It is still another object of the present invention to provide an insulated lunch bag that includes a housing having a soft outer surface and an insulated inner surface.


It is yet another object of this invention to provide such a device that is inexpensive to implement and maintain while retaining its effectiveness.


Further objects of the invention will be brought out in the following part of the specification, wherein detailed description is for the purpose of fully disclosing the invention without placing limitations thereon.
