A self-contained meal assembly comprises a heating bag, a food pouch, and a heating element. In operation, a heating element is placed along a bottom portion of a heating bag, a food pouch is placed inside proximate the heating element, a predetermined amount of water or other nonflammable aqueous liquid is added, and the heating bag is resealed thereby allowing an exothermic reaction to occur within the heating bag. One or more steam vents may be formed through a heating bag allow steam to discharge from the interior of the heating bag during operation. The configuration of the steam vent(s) allows a controlled release of high temperature steam from the heating bag as it circulates within the heating bag to the steam vent(s) at a safe discharge angle relative to the sides of the heating bag.

The present invention may be used for self-heating edible fluids without an external heating source, and no or minimal leakage or spilling. It may consist of a fully sealed container body that prevents the leakage or mixing of an activation substance and edible fluid. A body inside of the container may behave as conductive wall separating the activation substance and edible fluid to prevent mixing. The invention includes a chemical pack tool that may be punctured into the container and seal the punctured hole so the is no leakage. As the exothermic reaction takes place, a built-in vent or existing one-way valves/vents may be used to prevent excess pressure build up, and then pushed back in to fully seal the container again when it is no longer needed.

A food container using a heating element, which container enhances convenience since a user can simply inject water toward the heating element by opening an inflow passage of an outer container without removing an inner container, and can keep the heating element stable in a simplified structure since a space containing the heating element inside the outer container and a space containing water are formed to be divided by a protrusion jaw but to communicate with each other.

A lunch box container includes: a main container; and an auxiliary container configured to be accommodated in the main container, wherein the auxiliary container is made of a material heatable on an induction cooktop.

A sealed package is disclosed for a self-heating assembly that produces heat by virtue of a liquid reactant reacting exothermically with a solid reactant to heat a product. The sealed package includes an outer container, a lower support structure (e.g., of open cell foam) within the outer container, a layer of the solid reactant above the lower support structure and within the outer container, an upper structure (e.g., of open cell foam, as well) above the solid reactant and within the outer container, and an upper layer that is permeable to liquid and that extends across an otherwise open top of the outer container above the upper structure.

A thermal container for transporting hot fast food having a body that forms a main box which defines an internal space for the food, includes on the inside an internal receptacle for incorporating heat emitters and a double ventilation system for circulating air between the internal receptacle and the internal space, allowing the heat from the heat emitters to circulate towards the food, keeping it warm, and aeration towards the outside, avoiding steam condensation. The double ventilation system has internal air circulation slots in the internal receptacle and external ventilation slots and holes in the main box. The internal receptacle can be a separate box from the main box which fits over the inner base of the main box.

The present invention relates to exothermically heated and portable heater tray assemblies, systems, their use, including related methods of manufacture and kits. In addition, mobile applications utilized in conjunction with the heater tray assemblies and systems contemplated herein.

A self-heating product pouch has a first thin flexible material that surrounds and defines a product compartment. A second thin flexible material is coupled to an outwardly-facing surface of the first thin flexible material to define a first heater compartment that is outside, but thermally coupled to, the product compartment. A first thin porous substrate inside the first heater compartment. A granular reactant is distributed throughout the first thin porous substrate. A frangible container is inside the first heater compartment. A liquid reactant is inside the frangible container. The granular reactant and the liquid reactant are adapted to react exothermically upon contact with one another.

This invention describes a phase change material being 1,3-propanediol ester where the 1,3-propanediol ester can be either a 1,3-propanediol monoester or a 1,3-propanediol diester. This invention further describes the use of 1,3-propanediol ester as a phase change material for releasing or absorbing latent heat during melting or crystallization. This invention also describes the use of the phase change material for use in non-food and food applications.

A thermally-controlled container for wet tissue, includes a first containing portion, a second containing portion, and a thermal element. A first fastening portion extends along an edge of the first containing portion. A first insulation layer is located on the first containing portion. The second containing portion is coupling to the first containing portion. A containing room is defined between the first containing portion and the second containing portion for receiving the wet tissue. A second fastening portion extends along an edge of the second containing portion to detachably engage with the first fastening portion. A second insulation layer is located on the second containing portion. The thermal element is used for heating the wet tissue.
