The present invention mainly includes two parts, namely the substrate 1 and the coating Layer 2, the coating layer 2 is set on one side of the substrate 1, and then the side with the coating layer 2 is attached to the receptor 3. The shape of the substrate 1 is not limited, and can be designed according to the needs of use , Such as the mask in Figure 4A or the bandage in Figure 4B can be implemented arbitrarily.

Please refer to Fig. 2A, Fig. 2B and Fig. 2C, which are the cross-sectional schematic diagrams of the particles of the present invention, and the cross-sectional schematic diagrams of the irritated state of the particles (1) and (2), with supplementary reference to Figs. 1 and 4A As shown in Figure 4B, the coating layer 2 mainly includes a plurality of particles 21. The particles 21 include a shell 211 and at least one filler 212. The shell 211 has at least one accommodating space, and the filler 212 is disposed in As described in the containing space, the shell 211 is made of lipid, fatty acid, wax, mineral oil, glyceride, polysiloxane, or any combination thereof. The filler 212 is determined according to requirements and can be used for skin care. Active essence or disinfectant or medical agent for medical use, etc.

The housing 211 has a working temperature range, and the working temperature range is 30°C to 70°C. When the housing 211 is in this working temperature range, the housing 211 will gradually dissolve and become thinner until the housing 211 A hole appears to release the filler 212 inside.

Further, in addition to the above-mentioned temperature method, the housing 211 can cause holes to be generated in the housing 211 through pressure changes, such as pressing the coating layer 2 to cause the housing 211 to be broken due to force. The filling 212 is released.

In other words, in the state of general non-use, it is necessary to maintain low temperature and avoid heavy pressure to avoid the release of the filler 212 due to the rupture of the shell 211. When it is to be used, it can be dissolved by the above-mentioned temperature or broken by pressure. Or, the filler 212 is released to the receptor 3 to achieve the purpose of use.
