1. A heater device for heating objects, comprising:
- a first compartment having a quantity of heat generating material therein;
a second compartment having a quantity of activation material therein capable of activating the heat generating material upon mutual contact;
the first compartment and second compartment together being sized to present a heating surface to the object to be heated;
a divider positioned in the first compartment and extending into the second compartment forming a barrier to maintain separation between the activation material and the heat generating material;
an opening member mounted on the device positioned in alignment with the barrier of the divider; and
an access element positionable in the open member and movable into contact with the barrier of the divider to open the barrier and permit access of the activation material to the heat generating material to permit a heat generating reaction there between.

Abstract
A heater device for heating objects, including a compartment having a heat generating material and a second compartment having an activation material to generate heat upon mutual contact. The compartments are adapted to present a heating surface to the object to be heated. A divider is positioned in the compartments forming a barrier to maintain separation between reaction components until opened by an opening member positioned in alignment with the divider. An access element is movable into contact with the barrier to permit a heat generating reaction there between.

11. The device of claim 18, which further includes an object to be heated and a tab on the heat absorbing material, such that the device is adapted to be folded over the object so that the heat absorbing material is external to the object and the heating surface is proximate the object, and the tab is adapted to maintain the folded device with the heating surface proximate the object.

13. A heater device for heating objects, comprising:
-
a first compartment having a quantity of calcium oxide therein; a second compartment having a quantity of water therein capable of activating the heat generating material upon mutual contact; the first compartment and second compartment together being sized to present a heating surface to the object to be heated; a divider positioned in the first compartment and extending into the second compartment forming a barrier to maintain separation between the water and the calcium oxide; an opening member mounted on the device positioned in alignment with the barrier of the divider; and an access element positionable in the open member and movable into contact with the barrier of the divider to open the barrier and permit access of the water to the calcium oxide to permit a heat generating reaction there between, wherein the access element is a longitudinal member having an axis and a diameter sized to enter the opening member and having a length sufficient to reach the barrier of the divider, whereby movement of the access element against the barrier opens the barrier to permit access of the water to the calcium oxide. - View Dependent Claims (10, 14, 15, 16)
