Embodiment approach 1

[0030] Such as figure 2 As shown, the skin adhesive laminate 101 is composed of a disposable body warmer 110 as a heat donor and an adhesive 120 using an adhesive transdermal absorbent or the like as a drug.

[0031] Disposable heating bag 110 encloses exothermic agent 111 in flat exothermic agent containing layer 112, and on the upper surface of this exothermic agent containing layer 112, an air-permeable surface 113 made of a gas-permeable film is provided. The lower surface is provided with a second adhesive layer 114 . The exothermic agent 111 is a mixed powder formed by mixing iron powder, water, vermiculite, activated carbon, salt, etc., and is an exothermic agent that reacts with oxygen to generate heat. In addition, as an exothermic agent, the above-mentioned mixed powder may be molded into a sheet shape or an exothermic agent that holds the above-mentioned mixed powder in a sheet may be used. At least a part of the air-permeable surface 113 is air-permeable so that...

Abstract

The invention provides a skin patch laminate body, whereby it is possible to conveniently peel off only the heat imparting body after the exothermic effects of the heat imparting body are no longer present, and a new heat imparting body can be reattached on the skin patch body remaining on the skin. The skin patch laminate body is composed of a heat imparting body and a skin patch body having a skin patch functional layer. In the heat imparting body, a flat exothermic agent accommodating layer for accommodating an exothermic agent is formed, and a second adhesive layer is formed on a lower surface of the exothermic agent accommodating layer. The skin patch body has a base layer, and a skin patch functional layer. A first adhesive layer for adhering directly to the skin is formed on a lower surface of the skin patch functional layer. The second adhesive layer of the heat imparting body is affixed to an upper surface of the base layer of the skin patch body so that the base layer and the heat imparting body are integrated with each other, and the first adhesive layer of the skin patch body is affixed to the skin. The adhesive strength between the second adhesive layer and the base layer is less than the adhesive strength between the first adhesive layer and the skin or other surface.

Description

technical field [0001] The present invention relates to a skin-attached laminate including a heating element. Background technique [0002] Conventionally, when applying a transdermal analgesic and anti-inflammatory external adhesive plaster to warm the skin of the affected area, it has been proposed that a disposable warming bag is attached in advance to the back side of the drug application surface of the adhesive plaster (see Patent Document 1). [0003] Moreover, it has been proposed that in addition to the warming effect of the disposable foot warmer, the effect of improving the symptoms of cold syndrome is also sought, and the disposable foot warmer is provided with a protrusion that stimulates acupuncture points, and a structure using a magnet on the protrusion (see Patent Document 2). [0004] In addition, the following structure of patch integrated with a disposable heating bag has been proposed, which is characterized in that, in order to achieve the coordination ...
