Problems solved by technology

[0014] (5) Furthermore, since the fingertips directly touch the paste, the paste becomes unhygienic, and care must be taken when attaching it to the damaged skin, so it is not ideal
[0015] (6) Also, since the fingertips are in direct contact with the paste, there is a possibility that the medicinal ingredients contained in the paste may transfer to the fingertips
[0016] (7) In addition, the above Figure 16 In the preparation method of the patch shown, when the pinched portion of the lower release film 4b is bent in-line, in order to prevent springback, the bent portion is heated by ultrasonic heat sealing or the like to soften the material, Then bend it into any size and form it with nip rollers, so it is not suitable for materials with high melting point, and the material is limited. In addition, when the machine is stopped or restarted, the quality will become unstable, so careful confirmation and management are required.

Embodiment

[0061] 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.

[0063] 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.

[0064] 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 .

[0065] On the other hand, among the two peeling films bonded on the plaster surface, the second peeling film 42 positioned on the upper side is configured so t...

Embodiment approach 2

[0077] In this embodiment, the composition of the cataplasm 1 is the same as that of the previous embodiment. As a laminate, it includes a support 2, a plaster 3 coated on the entire surface of the support 2, and a paste attached to the plaster 3. Two stripping films 41,42 on the plaster face. In this embodiment, for example, the plaster 3 is a plaster 3 composed of sodium polyacrylate or the like as a coating paste 3 on almost the entire surface of the support 2, and the plaster 3 contains, for example, an anti-inflammatory and analgesic drug biphenyl Drugs such as acetic acid and water, etc.

[0078] In addition, in this embodiment, as the two release films 41 and 42, the second release film 42 on the upper side is a non-stretched polypropylene film with a thickness of 30 to 50 μm, and a release film that is embossed with a tortoise shell pattern.

[0079] On the other hand, for the first release film 41 on the lower side, a tube-shaped release film that has no stretched po...

Abstract

A method of producing a skin patch (1) which has a layered structure comprising a support (2), a pressure-sensitive ointment (3) spread almost allover one face of the support (2) and two peeling films (41 and 42) bonded to the ointment face, wherein the first peeling film (41) is a V-shaped peeling film folded at the center thereof and bonded to the ointment face so that the folded part of one face of the folded V-shaped peeling film faces toward the center of the ointment, while the second peeling film (42) is bonded to the remainder of the ointment face so that the edge (47) thereof covers the folded part of the first peeling film, characterized in that at least a half of the ointment face spared on the support (2) is bonded to a tubular peeling film and then the tubular peeling film is halved so as to form the first peeling film which is folded at the center thereof.

Description

technical field [0001] The present invention relates to a patch such as cataplasm for the purpose of anti-inflammatory, analgesic, or itching treatment, and a preparation method thereof. More specifically, it relates to an excellent patch and a method for producing the same, which can be easily applied from the peeling film to the patch even for elderly people or patients with poor grip strength, not only for healthy people. A series of operations with attached movements, and the hands do not touch the paste at all, which can be applied safely and hygienically.
