Embodiment

[0054] The present invention will be described below through several implementation modes constituting specific embodiments with reference to the accompanying drawings.

Embodiment approach 1

Fig. 1 shows patch preparations such as cataplasms in Embodiment 1 as an example of the present invention. Figure 1.1 for its stereogram, Figure 1.2 for side view.

[0056] The patch cataplasm 1 in the embodiment shown in FIG. The basic structure of the laminate of the two release films 41 and 42 on the paste surface of the paste 3.

[0057] Among the two peeling films bonded on the plaster 3 surface of the patch 1, the first peeling film 41 located on the lower side is configured in such a way that it has a V-shaped peeling film shape bent at its central part. One side of the bent V-shaped first peeling film 41 is pasted from the end of the above-mentioned plaster face, with the bent portion 44 facing the center of the plaster, and the other side of the V-shaped peeling film is used as the pinching portion 45 .

[0058] On the other hand, among the two peeling films attached to the plaster surface, the second peeling film 42 positioned on the upper side thereof is constitu...

Embodiment approach 2

[0069] In this embodiment, the composition of the cataplasm 1 is the same as that of the previous embodiment, including a support 2, a paste 3 coated on the entire surface of the support 2, and a paste attached to the paste 3 as a laminate. Two stripping films 41,42 on the plaster face. In this embodiment, the two peeling films 41 and 42 are peeling films that siliconize polyethylene terephthalate sheets with a thickness of 25 to 38 μm and then emboss with a diamond pattern.

[0070] In addition, in the two peeling films bonded on the surface of the paste body 3, the cut surfaces at the ends of the nip portions 45 and 46 are corrugated.

[0071] The method for sticking the cataplasm 1 of the present embodiment to the affected part is the same as the method of the above-mentioned embodiment. In the present embodiment, the material of the two peeling films is a polyethylene terephthalate sheet, and its sheet thickness is 25mm. ~38 μm, higher hardness than the non-extended polyp...

Abstract

It is intended to provide an adhesive patch which can be safely and hygienically applied without touching an ointment in the course of from stripping a stripping film to applying the patch. Namely, an adhesive patch having a laminated structure comprising a support, a sticky ointment spread on almost the entire face of the support and a stripping film adhered to the ointment face, characterized in that: (a) The stripping film adhered to the ointment face consists of two stripping films; (b) the first stripping film is a V-shaped stripping film which is folded at the center and one face of the thus folded V-shaped stripping film is adhered from the edge of the ointment face so that the folded part face the center of the ointment while the other face of the V-shaped stripping film is employed as a knob; and (c) the second stripping film is adhered to the remainder of the ointment face and a laminated part is provided so that the edge of the second stripping film covers the folded part of the first V-shaped stripping film, thereby employing the laminated part as a knob.
