Abstract

Abstract An improved lunch box assembly including a main housing having a lid portion and a base portion hingedly secured with one another so as to provide access to an opened interior of the improved lunch box assembly. Further, a display panel is included and secured in overlying relation to one exterior wall surface of the main housing so that it defines a pocket therebetween which is visually accessible through a display opening defined in the display panel. Also, a display insert is included and structured to be removably inserted into the pocket between the display panel and the exterior wall surface so that a primary display face thereof is visible through the display opening in the display panel and so that while it is securely maintained within the pocket when in use it can also be easily removed for convenient cleaning or interchanging with a new display insert.
