A carrying hand or a shoulder belt can be attached to the carrying case 9 as necessary to facilitate carrying.

The wet tissue storage unit 4 has a pair of wide rubber belts 10 and 11 disposed therein at appropriate intervals, and stops both ends of each of the rubber belts 10 and 11 at a position slightly below the opening edge. Thus, a so-called floating bottom 12 whose height changes in accordance with an increase / decrease in the content (wet tissue) is formed, and the rubber belts 10 and 11 constituting the floating bottom 12 are subjected to shrinkage (tensile force) of the content (wet tissue). ) Is always lightly pressed against the inner surface of the main lid 3 in the closed state.

On the inner side of the main lid 3, a pocket component 13 made of aluminum vapor-deposited cloth, which functions advantageously to reduce the risk of burns due to contact and to improve heat reflection, has the aluminum vapor-deposited surface outside. In this state, the pocket constituent pieces 13 are overlapped with each other, and the entire peripheral edge of the pocket component piece 13 except for the side near the base end of the main lid portion 3 meets the peripheral edge of the main lid portion 3 to provide the concealed pocket 14. A planar heat source body 15 to be described later is placed in the concealed pocket 14.

That is, power is received from the secondary battery 16 via the battery terminal 27, and a stable voltage is supplied to the heat source body 15 via the heater terminal 28 according to the switching operation of the switch 17.

After the heat source 15 reaches about 60 ° C. by continuous energization for about 8 minutes in an environment where the outside air temperature is 20 ° C., the power source control section 18 repeatedly turns off the power for 30 seconds and energizes for 40 seconds. An overdischarge prevention circuit is provided for the battery to shut off the current when the voltage drop due to the decrease in the battery capacity is detected during the continuous energization while performing the heat retention control.

The present invention can be carried out by making various modifications without departing from the spirit of the present invention, for example, as follows. Reach.・ Use waterproof cloth, heat insulating cloth, heat-resistant synthetic resin, or other materials instead of cloth.・ Use hooks, snaps, strings, etc. instead of fasteners.
