First, the drug layer protective material 1 and the adhesive surface protective material 4, which are adhered to each other so as to be peeled off, are peeled off and then attached to the affected part. In this case, since the drug layer protective material is silicone coated to increase the peeling force, the adhesive layer protective material is not necessary, and thus the drug layer protective material may be attached to the affected part after peeling only the drug layer protective material.

Although the manufacturing process of this invention is demonstrated based on the Example described below, this invention is not limited to the Example described below.

Example

The preparation of the poultice agent which has the adhesive face of this invention was performed as follows.

First, a drug was prepared according to a general method of preparing a poultice. Pharmaceutical drug was applied to the drug layer protecting material using a poultice coating wherein the coating thickness of the drug were controlled through the coating thickness control on the applicator, the size of the final sample 16.25 × 10 cm ² be when the final weight that is drug layer, The regulator was applied by adjusting the regulator so that the total weight of the double-sided adhesive tape constituting the drug layer protective material, the base material and the adhesive face was about 14 to 20 g. At this time, a 4.7 cm wide application barrier was installed at intervals of 14 cm to prevent the drug from being applied to this area, thereby securing a space in advance for the double-sided adhesive tape.

Nonwoven fabric was used as the base material. One adhesive side protective material of the pre-prepared 4.5 cm wide double-sided adhesive tape was removed and attached to the adhesive side to which the drug layer was attached to the base material at intervals of 14.2 cm.

The base material with the double-sided adhesive tape attached to the drug layer already applied. At this time, it was very important to attach the double-sided adhesive tape secured in advance to the drug layer protective material and the position of the double-sided adhesive tape previously attached to the base material.

The sample to which the base material was attached was cut into a size of 16.25 × 10 cm ² to measure the weight. At this time, when the final weight does not meet the desired weight, the coating thickness controller of the poultice applicator was adjusted again to apply the drug to prepare a sample of the desired weight.

The mounting position of the double-sided adhesive tape was prepared by attaching it in the longitudinal direction, that is, 10 cm in the longitudinal direction of the foaming agent in the manufacturing process.

The manufacture of the double-sided adhesive tape was performed as follows.

First of all, an organic solvent-based rubber pressure-sensitive adhesive was used as the pressure-sensitive adhesive material. If necessary, water-soluble acrylic pressure-sensitive adhesives, water-soluble rubber pressure-sensitive adhesives, and hot melt pressure-sensitive adhesives may also be used.

The adhesive material was applied to the pressure-sensitive adhesive protective material to a thickness of about 150um and then dried for 20 minutes in a drying oven at a temperature of about 95 ℃ and immediately attached to the adhesive surface base material on the dried adhesive surface. At this time, OPP transparent film was used as a base material. The adhesive material was applied to another adhesive surface protective material in the same manner, and the base material surface made before the adhesive surface was dried and reattached to the adhesive surface. This was cut into a 4.5 cm width to prepare a double-sided adhesive tape was used in the preparation of a poultice agent having an adhesive surface.

Figure 4 shows a method of using a poultice using a general close contact cloth, this is simply as follows when comparing the poultice having a pressure-sensitive adhesive of the present invention and its use method.

How to use general adhesive cloth

① Remove the adhesive on the center of the adhesive cloth

② Attaching a poultice agent to the center of the contact cloth

③ Remove the poultry drug layer protective material

④ Remove the adhesive pad protective surface

⑤ Attached to affected part

How to use the poultice agent having the adhesive side of the present invention

① Removing the poultice drug layer protective material

② Removing adhesive surface protection material

③ Attached to affected part

Or if the drug layer protective material is coated with silicone to increase the peeling force (no adhesive surface protective material is used)

① Removing the poultice drug layer protective material

② Attached to affected part

As described above, since the poultice having an adhesive face on both sides of the poultice agent of the present invention has an adhesive face, when the user wants to attach the poultice agent to the affected area, only the drug layer protective material and the adhesive surface protective material or the drug layer protective material are removed. It can be used quickly, and it has strong adhesive force compared to the poultice without contact cloth, so it does not fall easily even after attaching, so it can work comfortably.
