Problems solved by technology

[0008] However, the disposable heating packs of Patent Documents 1 and 2, or adhesive agent-applied surface and disposable heating pack or making bumps in the heating pack itself, are not formed as a separable disposable heating pack and provide therapeutic effects other than it. The structure of the part, when the heating effect of the disposable heating bag disappears, the part that provides the therapeutic effect other than the disposable heating bag should also be thrown away
[0009] In addition, the patch of Patent Document 3 is peeled off from the disposable heating bag when the heating effect of the disposable heating bag disappears, and a new disposable heating bag can be used again by sticking a new disposable heating bag on the patch, but it cannot be peeled off from the skin. To stretch the film of the patch and only peel off the disposable heating bag, it is necessary to peel off the film from the skin and then peel off the heating bag from the film
However, the pasting after the second time becomes easy to peel off due to the weakened adhesive force of the film, so how to simply peel off the heating element as a disposable heating bag and leave the other parts that provide therapeutic effects in skin problem

no. 1 Embodiment approach

[0063] figure 1 It is a cross-sectional view showing the first embodiment of the skin sticking laminate. like figure 1 As shown, the skin sticking laminate 1 is composed of a heat donor 10 , a skin sticking body 20 and an easily peelable adhesive layer 30 .

[0064] The heat imparting body 10 is formed in such a manner that two exothermic agent containing layers 12 accommodate the exothermic agent 11 in a flat shape from both sides. Air-permeable layer 13 that oxidizes and generates heat. By making both surfaces of the heat donor body air permeable, air can be further sent to the exothermic agent, enabling rapid heating. However, on the other side (easily peelable layer) side, it takes effort to form the easily peelable pressure-sensitive adhesive layer in order to supply air to the exothermic agent (details will be described later).

[0065]The skin sticking body 20 is provided with: a base material layer 21, which functions as the bottom layer of the skin sticking body 2...

no. 2 Embodiment approach

[0081] figure 2 It is a sectional view showing the second embodiment of the skin sticking laminate. The description overlapping with the above-mentioned embodiment is omitted.

[0082] The skin sticking laminate 1A is the same as the above-described embodiment in that it is composed of the heat donor 10A, the skin sticking body 20A, and the easily peelable pressure-sensitive adhesive layer 30A.

[0083] The heat imparting body 10A is formed so that two exothermic agent storage layers 12A accommodate the exothermic agent 11A in a flat shape from both sides, and in this embodiment, one exothermic agent accommodating layer 12A is formed for exposing the exothermic agent 11A to the air. And the heat-generating air-permeable layer 13A is oxidized, and the other heat-generating agent containing layer 12A is formed as an air-impermeable layer 14A that does not allow air to pass through. By making the surface bonded with the base material layer 21A of the skin sticker 20A an air-im...

Abstract

The invention provides a skin patch laminate body, from which a heat imparting body is simply peeled after the heat imparting body finishes heating. The skin patch laminate body is characterized by comprising a skin patch body 20 including a base layer 21 and a skin adhesive layer 22 being formed on one surface of the base layer for being directly applied to the skin and a heat imparting body 10 including an exothermic agent 22 and an exothermic agent-accommodating layer 12 that accommodates the exothermic agent therein, wherein the exothermic agent-accommodating layer 12 on one surface of the heat imparting body 10, and the other surface of the base layer 21 of the skin patch body 20 are attached to each other via a peelable adhesive layer 30.

Description

technical field [0001] The present invention relates to a laminated body that includes a heating element and is attached to the skin. Background technique [0002] In the past, when warming the skin of the affected area with a transdermal analgesic and anti-inflammatory external adhesive plaster, a disposable heating bag is previously bonded 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 heating effect of the disposable foot warmer, it also seeks the effect of improving the symptoms of cold syndrome, and that the disposable foot warmer has a protrusion that stimulates acupuncture points, and uses a magnet as the structure of the protrusion (see Patent Document 2). [0004] In addition, in order to achieve the synergistic effect of the warming of the heating bag and the warming stimulation of the plaster, it is proposed to provide an adhesive layer on the surfac...
