Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a plaster that is applied to the surface of the human body and is used for relieving symptoms such as muscle pain and stiffness.

[0002]

[Prior art]

 The conventional plaster of the type has a structure in which an adhesive layer is provided on one surface of a sheet-shaped base material, and the adhesive layer contains a medicinal component, and the sheet-shaped base material is made of rubber magnet or the like. There are those using a permanent magnet plate.

[0003]

[Problems to be solved by the device]

 This type of plaster lacks the function of protecting the affected area due to the thin thickness of the sheet-shaped substrate, and when an external force acts on the application site, the external force directly acts on the affected area, causing pain on the affected area. There's a problem.

The present invention has been made in view of the above problems, and an object thereof is to provide a plaster capable of protecting an affected area from external force by imparting a cushioning property to a sheet-shaped base material.

[0005]

[Means for Solving the Problems]

 The invention according to claim 1 is a plaster in which a pressure-sensitive adhesive layer is provided on one surface of a sheet-shaped substrate and the adhesive layer contains a medicinal component, and a cushion layer is provided on the sheet-shaped substrate.

The invention according to claim 2 is a plaster in which an adhesive layer is provided on one surface of a sheet-like base material having a magnetizing layer, and a cushion layer is provided on the sheet-like base material.

A third aspect of the invention is the plaster according to the second aspect, wherein the adhesive layer contains a medicinal component.

A fourth aspect of the invention is the plaster according to any one of the first to third aspects, in which the sheet-shaped base material is formed in a size that can be cut into arbitrary small pieces.

[0009]

[Action]

 Since the cushion layer is provided on the sheet-shaped base material, even if an external force is applied from above the attachment site, the cushion layer cushions the external force so that the external force does not directly act on the affected area and the affected area does not feel pain.

[0010]

【Example】

 FIG. 1 shows the appearance of a plaster 1 according to the first embodiment of the present invention. The plaster 1 comprises a sheet-shaped base material 2 and a release paper 3, and the sheet-shaped base material 2 is provided with a cushion layer 4 and an adhesive layer 5.

The pressure-sensitive adhesive layer 5 is formed by applying a pressure-sensitive adhesive 7 on one surface of a tough sheet 6 such as cloth, non-woven fabric, paper, etc., so that the release paper 3 can be peeled off on the coated surface of the pressure-sensitive adhesive 7. It is attached.

An acrylic adhesive or a rubber adhesive is used as the adhesive 7, and the adhesive 7 contains medicinal components such as a skin stimulant and an anti-inflammatory analgesic. As the medicinal component, for example, methyl salicylate, menthol, peppermint oil, etc. are used, but the medicinal component is not limited to these, and other medicinal components may be added.

The cushion layer 4 is formed by stacking and adhering an elastic plate material 9 such as sponge, urethane foam, or styrofoam on the other surface of the sheet 6, and its thickness is set to about 3 to 5 mm. If it is less than 3 mm, it lacks in cushioning effect, and if it is more than 5 mm, it becomes bulky and gives a feeling of strangeness.

As the release paper 3, kraft paper that has been subjected to a release treatment such as silicon coating, plastic film, cellophane, or the like is used.

FIG. 2 shows the external appearance of the plaster 1 according to the second embodiment of the present invention. In this embodiment, the sheet-shaped substrate 2 comprises a cushion layer 4, an adhesive layer 5 and a magnetizing layer 8, and the cushion layer 4 is constructed by using two elastic plate members 10 and 11.

The elastic plate members 10 and 11 are made of the same material as in the first embodiment, and the elastic plate members 10 and 11 are laminated and adhered to both surfaces of the flexible permanent magnet plate 12. A magnetizing layer 8 is provided between the cushion layers 4 and 4. It is desirable that the thickness of each elastic plate member 10, 11 is appropriately set so that the total sum thereof is about 3 to 5 mm.

The permanent magnet plate 12 is made by kneading a powder of a permanent magnet material such as ferrite and an elastic material such as rubber or elastic plastic, and rolling the mixture into a thin plate. It is formed by cutting to the size of. The permanent magnet plate 12 having the N pole on one surface and the S pole on the other surface is formed by the above-mentioned magnetizing treatment. The magnetizing such that the N and S magnetic poles are formed in strips and are alternately inverted. It may be treated.

In the case of this embodiment, the adhesive layer 5 is formed by directly applying the adhesive 7 on the surface of the second elastic plate material 11. However, as in the first embodiment, the cloth, the nonwoven fabric, The pressure-sensitive adhesive 7 may be applied to one surface of a tough sheet such as paper and the other surface of the sheet may be bonded to the elastic plate member 11. Note that the release paper 3 is releasably attached to the coated surface of the adhesive 7 as in the first embodiment.

FIG. 3 shows the external appearance of the plaster 1 according to the third embodiment of the present invention. In the third embodiment, similarly to the second embodiment, the cushion layer 4 and the magnetizing layer 8 are formed with the permanent magnet plate 12 interposed between the first and second elastic plate members 10 and 11. However, for the adhesive layer 5, the adhesive 7 is applied to one surface of a strong sheet 6 such as cloth, nonwoven fabric, or paper, and the other surface of the sheet 6 is adhered to the elastic plate material 11. Contains medicinal ingredients such as skin stimulants and anti-inflammatory analgesics.

In each of the above examples, the paper 3 is peeled off and attached to the affected area as it is, but as shown in FIG. 4, the sheet-shaped substrate 2 can be cut into small pieces of arbitrary size. It may be formed into a size. In the case of this example, the size is cut according to the size of the affected area, and the small piece is attached to the affected area. Note that vertical and horizontal cutting lines 13 as shown in FIG. 4 may be shown on the surface of the release paper 3, and by cutting along the cutting lines 13, small pieces of various sizes may be obtained. The embodiment of FIG. 4 has the same laminated structure as the third embodiment of FIG. 3, but has the same laminated structure as the first embodiment of FIG. 1 and the second embodiment of FIG. May be.

In wearing each of the embodiments of FIGS. 1 to 3, after the release paper 3 is peeled from the sheet-shaped substrate 2, the adhesive layer 5 is placed downward as shown in FIG. Is positioned on the affected area and attached to the skin surface 14.

In the embodiment of FIG. 1, the medicinal component contained in the adhesive layer 5, the magnetic force line from the magnetizing layer 8 in the embodiment of FIG. 2, and the medicinal component and the magnetic force line in the embodiment of FIG. Each acts on the affected area to relieve symptoms.

When an external force is applied from above the application site, the cushion layer 4 is provided on the sheet-shaped base material 2. Therefore, the cushion layer 4 does not directly apply the external force to the affected area, and the affected area feels pain. Do not let

[0024]

[Effect of device]

 According to this invention, as described above, since the cushion layer is provided on the sheet-shaped base material, even if an external force acts on the affixed site, the cushion layer cushioning action does not directly act on the affected area, causing pain on the affected area. Do not feel. Further, in the invention according to claim 4, since the sheet-shaped base material is formed into a size that can be cut into arbitrary small pieces, the sheet-shaped base material is cut into a size according to the size of the affected area and the small piece is attached to the affected area. That is, the practical effect is remarkable.
