BACKGROUND

Food spoilage is a natural occurring process. When food is subjected to temperatures in the “danger zone” above 40 degree F. and below 140 degree F. the toxins multiply at an exponential rate. The toxins in turn leave bacteria on your food. Bacteria, yeasts and molds are among common causes of spoilage and food poisoning. Chilling food helps delay the food poisoning and spoiling process because the toxins grow at a slower rate, thus leaving fewer bacteria, and keeping food safe to eat for a longer period of time. Many portable containers are available to keep food chilled for a period of time. One impact of chilling food is that it can impact sensory details such as texture, taste, and smell. Human beings evolved to prefer hot food. Warmth enhances flavor on the sensory papillae of our tongues and heating food boosts its energy value.

The exterior plastic parts may be fabricated using plastic injection, co molded silicone injection, Surface Mount (SMT) assembly providing low cost and scalable manufacturing systems of one embodiment.

Heat Plate Assembly Insert:

FIG. 37shows for illustrative purposes only an example only an example of an exploded view of a small pizza delivery bag of one embodiment.FIG. 37shows the food transport warming system heat plate assembly insert3701components. An integrated insulating back layer3703is coupled to a heat plate3702to provide insulation from a heat plate3702protecting a small pizza delivery bag and directing heat inward. A battery box3607configured to hold at least one battery3609. In some embodiments the heat plate3702may have a cloth silicone or other material protective covering.

The heat plate assembly insert3701is configured to be easily portable so that food can be warmed in multiple diverse and varying small pizza delivery bags3600ofFIG. 36. The heat plate assembly insert3701devices are self-contained and food safe. Power is supplied by a customized rechargeable battery pack3609. Heating power, charging and battery safety circuits are all contained in the PCBA3610ofFIG. 36. When the system is activated the PCBA3610ofFIG. 36will convert electrical energy to heat energy and disperse it through conductors including for example the heat plate assembly insert3701or other conductors of one embodiment.

The battery box3607is connected to the heat plate3702with a heating plate plug3707. The heat plate assembly insert3701is placed along the sides of the small pizza delivery bag3600ofFIG. 36and, in some embodiments; multiple units may be used in one small pizza delivery bag3600ofFIG. 36. The heat elements transfer heat into the small pizza delivery bag3600ofFIG. 36to help keep food warm. The small heat plate assembly insert3701systems are attached to the inner surface of the small pizza delivery bag3600ofFIG. 36with Velcro3704in one embodiment. Other embodiments could include brackets, clips, or other attachment systems.

The heat plate assembly insert3701may be configured in shapes and sizes for various small pizza delivery bag3600ofFIG. 36types and sizes. For example one shape and size for a small pizza delivery bag3600ofFIG. 36, in another example for a larger pizza delivery bag with an optional shelf system3907ofFIG. 39. In other embodiments the heat plate assembly insert system devices may be configured for specific food types for example configured in shapes and sizes for various pizza delivery bag types and sizes.
