FIELD OF THE INVENTIONThe invention relates generally to the field of food serving and containers but more particularly to a lunch box that can unfold into a placemat.
BACKGROUND OF THE INVENTIONThere are several inventions in the field of food serving that present products that have two uses. Most have to do with combining utensils with placemats. Others are more like trays with predefined cavities that act like bowls or plates.
There are of course a variety of boxes which can be unfolded into flat pieces of cardboards designed for single use but these patents are generally for the manufacturing process or to disclose means for storage of boxes which are made out of flat sheets of cardboard.
There does not appear to be a practical way to provide for a lunch box that also acts as a placemat.
SUMMARY OF THE INVENTIONIn view of the foregoing disadvantages inherent in the known devices now present in the prior art, the present invention, which will be described subsequently in greater detail, is to provide objects and advantages which are:
To provide for a lunch container or lunch box which can be easily unfolded to create a practical placemat.
To provide for a lunch container that is designed for multiple usage and not for one time disposable usage.
To provide for a lunch container that can easily be carried about by hand or on a bicycle rack or such racks.
To provide for a lunch container having insulating capabilities.
To provide for a lunch container wherein the placemat configuration presents a useable surface that is easy to clean.
To provide for a lunch container with features such as holding straps for utensils and optional integrated pouch.
To provide for a container that can be used for a variety of other purposes besides carrying food, such as a make up kit.
To attain these ends, the present invention generally comprises a collapsible lunch box adapted to be formed into a placemat, the lunchbox comprising a front panel member; two side panel members connected to the front panel member along two opposite side edges of the front panel member; a bottom panel member connected to a bottom edge of the front panel member; a back panel member connected to a bottom edge of the bottom panel member opposite from the bottom edge of the front panel member; and a top panel member connected to a bottom edge of the back panel member opposite from the bottom edge of the bottom panel member; wherein side edges of the two side panel edges are adapted to be removably connected to side edges of the bottom, back, and top panel members to form the collapsible lunch box, and disconnected to form the placemat.
The placemat is adapted to lay flat on the surface of a table member and defines two surfaces; one of the two surfaces is an inside surface formed from a cotton material having an inner face laminated with a metalized finish; the second of the two surfaces is an outside surface formed from a layer of material having a rough texture that is adapted to limit slipping relative to the surface of a table member and is adapted to be on the outside of the lunch box when the side panel members are connected to the bottom, back, and top panel members, and is adapted to contact the table member surface when the side panel members are disconnected from the bottom, back, and top panel members forming the placemat; and a layer of insulating material located in between the inside and outside surfaces.
In a preferred embodiment, the connections between the side panel members and the front panel member are flexible.
In another aspect of the invention, the removable connections between the side panel members and the bottom, back, and top panel member include zipper members.
In a preferred embodiment, the insulating material of the inside surface is formed from POLAR.
The rough textured material of the outside surface is formed from nylon.
The zipper members are formed from nylon.
In a preferred embodiment the zipper members are formed as first and second zipper members, wherein the first zipper member runs along at least three sides of one of the side panel members, and the second zipper member runs along all four sides of the other of the side panel members and the side of the front panel member opposite the bottom panel member. The second zipper member also runs along a side of the side panel member that the first zipper member is not located.
