Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 202 words
A lunch box or similar apparatus, comprising: a. a load accommodating assembly having a bottom surface and first, second, third and fourth side surfaces, to thereby form a box-like structure with a top open surface, said bottom surface and said side surfaces fabricated from a relatively hard substance of an opaque nature and at least one surface having imprinted thereon permanent graphic data, b. a cover member pivotally mounted to one of said side surfaces to cover said top open surface in a closed position, c. said exposed outer areas of said bottom surface, and said first, second, third and fourth side surfaces covered by a smooth transparent plastic material to enable said permanent graphic data to be viewed, said transparent plastic capable of having applied thereto graphic data impressed thereon by means of a waxy crayon writing substance, d. said inside surface of said cover member facing said top open surface further covered by said smooth plastic material, to also enable application thereto of erasable graphic data by said waxy crayon writing substance, and e. means secured to one of said surfaces forming said box-like structure and within the load accommodating portion of said assembly for accommodating a waxy crayon instrument.
