1. Field of the Invention
The invention generally relates to container systems.
2. Description of Related Art
There are several inventions relating to the temporary storage of food for later consumption, such as lunchboxes. In the past, some lunchbox designs were made out of rigid material, such as metal or a hard plastic. Later developments in thermal insulation gave way to lunchboxes being made out of a softer material. The outside of these softer lunchboxes would generally be made of nylon, while the inside would generally be made of an easily cleanable water resistance material. Sandwiched between the nylon and water resistant materials would be a thermal insulator to better keep any food contained within the lunchbox at its original temperature.
However, while these soft lunchboxes were useful for the storage and transportation of food, they generally had limited use beyond this function. Further, if one had a need for a placemat, one would either need to carry the placemat separate from the lunchbox or place the placemat inside the lunchbox, taking valuable space which could be used for food storage.
A container system foldable into a placemat includes a front panel, a back panel, a center panel, and a border panel. The front, back, and border panels each include an inner edge and an outer edge. The center panel includes three inner edges and an outer edge. The center panel may be foldably connected to the front, back, and border panels, such that a first inner edge of the center panel may be adjacent to an inner edge of the front panel. A second inner edge of the center panel may be adjacent to an inner edge of the back panel, and a third inner edge of the center panel may be adjacent to an inner edge of the border panel. An attachment mechanism extends along the outer edges of the center, front, back, and border panels. The attachment mechanism allows closure of the container system to define the substantially enclosed interior space.
In one embodiment, the attachment mechanism may include a starting point and an ending point. The starting point may be substantially adjacent to an intersection of the front, center, and border panels. The ending point may be substantially adjacent to an intersection of the back, center, and border panels. However, the starting point and the ending point may be located at any suitable location.
In another embodiment, the attachment mechanism may be a zipper tooth track system. In this embodiment, a zipper head engages the zipper tooth track system, so as to allow the opening and closing of the container system.
In yet another embodiment, the front panel and/or back panel may have a flap attached. When the flap is in a folded position, the flap can be stored within the container system. When the flap is unfolded, the flap functions to increase the surface area when the container system is unfolded into a placemat.
Further objects, features, advantages and embodiments of this invention will become readily apparent to persons skilled in the art after a review of the following description, with reference to the drawings and claims that are appended to and form a part of this specification.

The center panel 16 may be foldably connected to the front panel 12, the back panel 14, and the border panel 18. More specifically, the first inner edge 32 of the center panel 16 may be adjacent and foldably attached to the inner edge
of the front panel 12. The second inner edge 34 of the center panel 16 may be adjacent and foldably attached to the inner edge 24 of the back panel 14. In like manner, the third inner edge 36 of the center panel 16 may be adjacent and foldably attached to the inner edge 28 of the border panel 18.
The front panel 12, back panel, 14, center panel 16 and border panel 18 may be rectangular in shape. However, as will be described in the paragraphs that follow, the front panel 12 and back panel 14 may be any suitable shape. The surface areas of the front panel 12 and back panel 14 may be substantially equal to one another. Additionally, the surface areas of the front panel 12 and/or back panel 14 may be larger than the surface area of the center panel 16. For example, the surface areas of the front panel 12 or back panel 14 may be greater than or equal to the surface area of the center panel 16.
The front panel 12, back panel, 14, center panel 16 and/or border panel 18 may be made of a flexible material, such as nylon. At least one side of the front panel 12, back panel, 14, center panel 16 and/or border panel 18 may be constructed of or covered by a water resistant material.
An attachment mechanism 40 extends along the outer edges 22, 26, 30, and 38 of the front panel 12, back panel 14, border panel 18, and the center panel 16, respectively. The attachment mechanism 40 has a starting point 42 and an ending point 44. The starting point 42 may be substantially adjacent to an intersection of the front panel 12, the center panel 16, and the border panel 18. The ending point 44 may be substantially adjacent to an intersection of the back panel 14, the center panel 16, and the border panel 18. However, the starting point and ending point 44 may be located at any suitable location. The attachment mechanism 40 allows closure of the container system 16 to define a substantially enclosed interior space 46.
The attachment mechanism 40 may include a first zipper tooth track 46 and a second zipper tooth track 48. The first zipper tooth track 46 starts at the starting point 42 and ends at the ending point 44, extending along the outer edges 22, 38, and 26 of the front panel 12, center panel 16, and the back panel 14, respectively. The second zipper tooth track 48 starts at the starting point 42 and ends at the ending point 44, extending along the outer edge 30 of the border panel 18. Further, the attachment mechanism 40 includes at least one zipper head 50 that engages the first zipper tooth track 46 and the second zipper tooth track 48 and is configured to attach and detach the first zipper tooth track 46 to the second zipper tooth track 48. Additionally, the attachment mechanism 40 may optionally include a second zipper head 51 that engages the first zipper tooth track 46 and the second zipper tooth track 48 and is configured to attach and detach the first zipper tooth track 46 to the second zipper tooth track 48.
While this embodiment discloses that the attachment mechanism 40 is a zipper system, it should be understood that any number of different attachment mechanisms may be used. For example, the attachment mechanism 40 may be a hook and loop fastener where the hook fastener is configured to removably engage the loop fastener. Additionally, the attachment mechanism 40 may be a series of buttons, snappable attachments, magnetic attachments or an adhesive attachment system.

The first flap 52 further includes retainers 56, and 58, that mate with retainers 60 and 62 that are located on the first panel 12. When in a mating position, the first flap 52 is retained to the front panel 12, as best shown in
The retainers 56, 58, 60, 62, 64, 66, 68, and 70 may be any type of retainer capable of holding the flaps 52 and 54 to the front panel 12 and back panel 16, respectively. Retainers 56, 58, 60, 62, 64, 66, 68, and 70, may be hook and loop fasteners, buttons, snaps, magnets, or adhesives, or any system capable of retaining the flaps 52 and 54 to the front panel 12 and the back panel 16, respectively.

The second section 90 may be foldably attached to the first section 88 and the third section 92. This allows the border panel 18 to be folded at the intersections between the second section 90 and the third section 92 and the intersection between the first section 88 and the second section 90. As best shown in
As stated previously, the front panel 12 and back panel 16 may take a variety of different shapes. For example, referring to
