Abstract
The present invention provides a heat package wherein a surface of a generating heat element that generates heat when exposed to atmosphere is placed against or attached to a heat conductive member. The heat element is protected from atmosphere until use. The heat package may include a heat-generating element attached to an insulating member with one or more air spaced there between. An outer surface of the heat-generating element can be exposed to atmosphere to produce heat when desired.
Claims17
A disposable heat package, comprising:
- a container formed using an insulating member;
- a heat-generating element in the container, wherein the heat-generating element generates heat when it comes in contact with the outside air;
- a heat-conductive container configured to contain a material to be heated, placed on the heat-generating element for transferring heat from the heat-generating element to the material inside the heat-conductive container, wherein the heat-generating element is placed only on one of a side and bottom surface of the heat-conductive container;
- and
- a disposable seal for protecting the heat-generating element from the outside air, and wherein the heat-generating element is exposed to the outside air only when the disposable insulating member is removed from the container formed of the insulating member.

A heat package, comprising:
- a heat-conductive container configured to hold therein a material to be heated;
- a heat-generating element attached to an outside surface of the heat-conductive container, the heat-generating element configured to generate heat when exposed to an outside air;
- and
- a removable seal configured to seal an outside surface of the heat-generating element, wherein the heat-generating element is exposed to the outside air to generate heat only when the seal is removed from the heat-generating element.
