Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a patch for use on the skin.

[0002]

2. Description of the Related Art The quality required for a patch is that the intended effect (treatment, prevention, inspection, etc.) is first exhibited, but it is also required that the patch does not stand out or smell when applied. To be done. On the other hand, in some cases, the date and time of application and the time of application are written on the surface of the patch in order to remember the information when applying. In particular, in the case of a patch for administering a drug for the purpose of treatment, it is necessary to periodically replace the patch, and it is important to fill in important information more than being inconspicuous.

However, there is no convenient conventional patch having a space for entry, and a white base material or the like is used as a support to give a clean feeling, and a transparent or semitransparent base is used. It was only devised to make it inconspicuous with the base material or to color the skin color system at best. For this reason, it was uncertain that the necessary information was relied on for memory and that even if it was filled in, there was omission. Further, since the surface of the support is not selected for writing, there is a problem that ink is repelled when writing with a pen or the like, and the ink is later dropped off to stain clothes.
