Another important feature of this invention is that food may be stored in the lunch bag for several hours without being deteriorated or turning cold, particularly in hot weather due to the refrigerating effect imparted by the frozen ice pack and due to the heating effect imparted by the heating elements inserted therein.
In one embodiment, the lunch bag device comprises a body component that is configured in a rectangular shape but can be any suitable shape as is known in the art. The body component comprises an interior cavity, defining a heated section or chamber, and a cooled section or chamber, which are separated by a divider. Specifically, the body component comprises an upstanding peripheral wall defining the rectangular configuration and the divider which forms the two internal chambers or sections for carrying hot and cold food. The two chambers open upwardly and are closed by a flip cover. The chambers each have a floor from which projects opposing side walls, and front and back walls. Specifically, the lunch bag device is of the open-top type construction and comprises a front wall, a back wall, a floor, and a pair of side walls, forming an interior rectangular cavity which is bisected by the divider.
In one embodiment, the interior cavity is divided into two food containing sections or chambers. Thus, the interior cavity of the body component is comprised of two halves. Each of these halves or sections is an internal compartment. Also, the flip cover acts as an insulating cover and has a flat surface, which is used to seal each of these sections when closed. The divider is a permanent interior wall in the middle of the interior cavity, which helps separate the two sections, such that section one does not affect the temperature in section two and vice versa. In another embodiment, the body component can be divided into a plurality of sections adapted to contain foods via the use of more than one divider. Any suitable number of sections can be created by using the dividers, as is known in the art based on the wants and/or needs of a user.

In this embodiment, an insulating material is disposed between the outer walls of the body component and the inner liner and is disposed substantially evenly between the outer walls and the inner liner filling the space therebetween, to protect the food contents placed in the food sections from losing their temperature. Typically, the insulating material suitable for use in making the body component of this invention may be formed of a lightweight polymeric material, such as polystyrene or polyurethane foam. Further, in this embodiment, each of the body component's walls comprise an outer wall and an inner wall, with all of the walls being made of a suitable flexible fabric or plastic material and being preferably waterproof or water repellent.
In one embodiment, the inner liner may be a separate structure from the outer wall, or it may also be secured either adhesively or by stitching or by any other suitable method directly to the inner surface of the outer walls, thereby forming a unitary composite inner wall of the body component. In this embodiment, the outer walls of the body component are formed of a suitable cloth or plastic material, while the inner liner is made of a waterproof material, such as a flexible plastic film or a rubber-treated fabric, and comprise a space for a frozen ice pack or heating element to keep the food contents in the sections cold or hot.
In one embodiment, the flip cover is secured to and hinges from the back wall of the body component. When in place to cover the interior cavity, the flip cover acts as an insulating cover and has a flat surface, which is used to seal each of the food sections when closed. Typically, the flip cover has a manually removable attachment element in the form of a latch. The latch is disposed to engage and be manually released from engagement with the front wall of the body component. The body component further includes a carrying handle or multiple handles and a carrying strap, both fixed to opposing side walls of the body component. The handle is small in length relative to the carrying strap and also is rigid. The carrying strap is much greater in length and is flexible compared to the handle. Having both assures maximal convenience when carrying and transporting the lunch bag device. Further, the handle and carrying strap may be formed, if desired, of the same material as the outer wall of the body component. The handle and strap are affixed by stitching or sewing one end thereof to the upper portion of the side wall of the body component, the other free end of the handle and strap being either stitched or sewed or detachably fastened to the upper portion of the opposing side wall by conventional cooperating snaps or similar fasteners.
In one embodiment, the body component comprises a conventional zipper instead of a flip cover for closing the device. Specifically, in this embodiment, the means for opening and closing the body component is a conventional zipper disposed across the top of the body component for the removable placing of food items and of the ice pack or heat element therein. When the lunch bag device is closed by means of a zipper, a substantially air-tight seal is formed, whereby a refrigerating and/or heating temperature may be maintained inside the food chambers of the body component in the presence of the inserted ice pack or heat element.
In one embodiment, the lunch bag device is made of a very strong, durable, and washable material as is known in the art, such as, but not limited to, polypropylene, polycarbonate, polyethylene, polyethylene terephthalate, polyvinyl chloride, polystyrene, etc. Generally, the lunch bag device is also manufactured from a material that is water resistant or waterproof, or the body component comprises a coating that is water resistant or waterproof.
