Description
BACKGROUND OF THE INVENTION
This invention relates to load accommodating structures,
particularly to such structures for containing school children's
lunches and the like.
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 box-like 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 have the
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
the impressed 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.

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 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 cloth 28.
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.
