It is apparent that there presently exists a wide variety of apparatus commonly designated as lunch boxes and used by school children for carrying their lunches to school. Such apparatus is similar in nature in that they all possess the same general appearance of a boxlike assembly with a cover member pivotally secured to a side surface for opening and closing the lunch box for access to the contents.

The usual devices are fabricated from metal, wood or hard plastic in order to protect the contents enclosed therein. It is not uncommon that school children who possess such apparatus use the same to strike others and a great many injuries occur due to such uses.

Besides this problem is the general discipline problem commonly associated with school lunch periods. It is desirable in order to maintain good discipline to keep the children busy and to restrain them from fighting and so on. The teacher or supervisor of such a lunch period would attempt to have the children work when they finish lunch or engage in some artistic endeavor. The problem in doing this is that lunch rooms or similar places do not havethe facilities to permit such endeavors.

BRIEF DESCRIPTION OF PREFERRED EMBODIMENT The present invention serves to alleviate the above problems by providing a lunch box having exposed surfaces covered with a soft smooth plastic capable of accommodating crayon writing and capable of being easily erased. Embodiments of this invention include fixed graphic data impressed on the outside exposed surface of the lunch box, which surface is covered by a smooth, transparent plastic material, thus enabling the child or operator to color according to theimpressed data on the surface thereof. Other embodiments include crayon accommodating pouches secured to appropriate inside surfaces of the lunch box to provide a child with a complete dual purpose apparatus, one capable of transporting food as well as enabling the child to color, draw on the surfaces thereof, while further providing impact protection to therefore import greater safety standards to such apparatus.

BRIEF DESCRIPTION OF DRAWINGS FIG. 1 is a plan view of a lunch box according to this invention.

FIG. 2 is a front view of a lunch box according to this invention.

FIG. 3 is a front view of an alternate embodiment of a lunch box.

FIG. 4 is a cross sectional view of a typical surface of the lunch box according to this invention.

FIG. 5 is across sectional view of an alternate embodiment of a surface of a lunch box.

DETAILED DESCRIPTION OF FIGURES Referring to FIG. 1 numeral 10 references a typical lunch box configuration. Although the unit is shown as a rectangular box-like assembly, it is understood that I other geometrical configurations will serve as well.

The lunch box 10 has an open top surface 11, which can be covered at will by means of the pivotally mounted cover assembly 12. Such cover assemblies 12 are conventionally mounted to an appropriate side surface by means of hinges 14 or other suitable devices. The cover assembly includes a clasp 15 which conventionally coacts with a corresponding catch member 16 on the appropriate side surface.

A handle member 17 is shown to enable a child or other operator to conveniently carry the lunch box.

Such lunch boxes, as indicated, are typically fabricated from metal, wood or plastic all of which are relatively hard and sturdy. The lunch box 10 as shown is also fabricated from such a material, but the exposed surfaces thereof are covered by a layer of smooth plastic, such as a vinyl plastic 20. The plastic may be glued by means of a transparent epoxy substance onto the exposed surface of the lunch box or alternatively be placed over the surfaces and stitched at the edges thereof. In any event the corners and edges of the bottom and four side surfaces may be covered by a soft pliable material such as vinyl covered cotton or fiberglass mold 21. The molding serving to protect the apparatus and user from impact.

The vinyl covering 20 has a smooth surface which serves to accommodate writing by means of a waxy substance as a crayon. Due to the relatively low frictional coefficient of such surfaces the adhesion between crayon is not strong and hence the writing can be easily wiped off by means of a suitable cloth or towel.

The cover member 12 has both the outside surface (not shown) and inside surface covered by a smooth vinyl plastic material 22. The inside of the cover member 12 may have imprinted on the relatively hard base material a series of lines 24 and other data, such as letters of the alphabet and so on. The cover member 12 also may include a crayon accommodating pouch 25, with a cloth accommodating pocket 26. The lunch box 10 therefore includes a plurality of crayons 27 and an erasing cloth28.

Hence, the child after lunch can use this lunch box as a portable desk top or writing surface. The child removes any desired crayon 27 from the' pouch 25 and can practice penmanship on the lines 24 or color or draw on any of the outer surfaces. The child can erase any data by using the cloth as by wiping the crayon off and so on.

A crayon pouch 30 can also be located on a side surface and can have a cover to prevent the crayons from spilling out during transport of the lunch box assembly.

The apparatus therefore serving the above noted multiple functions, while the cost of the apparatus remains virtually unchanged due to the inexpensive costs of the vinyl covering as well as the crayon pouch and crayon tools. The relative dimensions of such a lunch box may vary but typically are about 7 inches by 8 inches and approximately 3 to 4 inches deep.

FIG. 2 shows either the top or bottom surfaces laminated with a smooth, crayon writing accommodating plastic 35, stitched over the appropriate surfaces.

FIG. 3 shows a top or bottom surface of a lunch box 40 wherein the smooth plastic laminate is a transparent vinyl 41. The surface has a base member 42 fabricated from a metal, wood or hard plastic upon which the outline of a scene is permanently impressed on a white, yellow or other contrasting background. The child can now color the scene as desired. It is of course understood that any graphic data can be so included. For example, the data instead of the landscape shown may include outline drawings of popular TV shows, storybook scenes, sports events and so on. The graphic data can be selected according to the age group desired, the sex of the child and therefore include educational data, as

arithmetic problems and so on.

FIG. 4 shows a cross section of a typical side member. The bottom or base layer 42 is, as indicated, fabricated from a hard substance. It is upon this substance that the fixed graphic data can be impressed. The base layer 40 has laminated thereon a smooth plastic cover layer 45, of a suitable vinyl and so on to accommodate crayon writing while permitting easy erasing by means of a suitable cloth or other material. Layer 45 can be bonded to layer 44 directly or by means of sticking and so on. For direct bonding a clear epoxy or glue is used.

FIG. 5 shows a base layer 50, an intermediate layer 51 and a smooth plastic laminate layer 52. The intermediate layer 51 is fabricated from a soft pliable material as a sponge, rubber or cotton composite. This acts as a cushion to further protect against impact. In this case the vinyl layer is opaque and attractively colored and can again directly accommodate crayon or waxy substance imprints.

Such data can be easily removed by means of a cloth 28 as shown in FIG. 1.

The apparatus therefore provides a versatile assembly for a school child and alleviates many problems as described above.

While the invention has been particularly shown and described with reference to the above figures, it will be understood by those skilled in the art that the foregoing and other changes in form and details may be made therein without departing from the spirit and scope of the invention.
