Accordingly, it may be appreciated that there continues to be a need for a new and improved illuminated lunch box as set forth by the instant invention which addresses both the problems of ease of use as well as effectiveness in construction and in this respect, the present invention substantially fulfills this need.

In view of the foregoing disadvantages inherent in the known types of lunch box apparatus now present in the prior art, the present invention provides an illuminated lunch box wherein the same is arranged to provide for illumination during use of the lunch box structure. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved illuminated lunch box which has all the advantages of the prior art lunch box apparatus and none of the disadvantages.

To attain this, the present invention provides a lunch box arranged for illumination during conditions of limited available light, wherein the lunch box includes an upper housing pivotally mounted to a lower housing, with illumination chamber positioned to a top wall of the upper housing and operative through a switch positioned rearwardly of the illumination housing relative to an associated handle. An electrically transmissive hinge is mounted between the upper housing and lower housing to direct electrical communication between batteries mounted within the lower housing to the illumination chamber within the upper housing.

My invention resides not in any one of these features per se, but rather in the particular combination of all of them herein disclosed and claimed and it is distinguished from the prior art in this particular combination of all of its structures for the functions specified.
