AI Technical Summary
Conventional large disposable warmers with divided release paper cause clothing damage due to repeated adherence to the same place, leading to fiber peeling and garment deterioration.
The release paper on the adhesive surface of disposable warmers is divided into four or more sections to reduce the adhesive contact area, allowing alternating attachment to minimize garment damage.
This division method reduces clothing damage by half, extending the lifespan of garments by maintaining adhesive strength while minimizing surface area contact.

Abstract
Description
Technical Field
[0001] The present invention relates to a disposable warmer to be attached to clothing.
Background Art
[0002] Conventionally, in the case of a large-sized disposable warmer to be attached to clothing, a release paper on the adhesive surface is known to be divided into two or three sheets.
Patent Documents
[0003] Searching for "disposable warmer" in J-PlatPat, nothing related to the release paper was found.
Summary of the Invention
Problems to be Solved by the Invention
[0004] In a disposable warmer, those having an adhesive surface to be attached to clothing have a release paper attached to the adhesive surface. In a small disposable warmer, the release paper is not divided, but in a large disposable warmer, there is one in which the release paper is divided into two or three parts. In many cases, the part of the body to be warmed by the disposable warmer is determined by the person. Then, the adhesive surface of the disposable warmer will be repeatedly attached to the same place on the clothing. Since the place where the disposable warmer is attached to the clothing is the same, when peeling off the disposable warmer from the clothing, the fibers on the surface of the clothing adhere to the adhesive surface and are peeled off, so the clothing will be damaged by repeated use of the disposable warmer. The present invention is devised to reduce the damage to the clothing to which the disposable warmer is attached.
Means for Solving the Problems
[0005] Divide the release paper on the adhesive surface of the disposable warmer into four or more parts.
Effects of the Invention
[0006] For example, if the release paper is divided into four sections horizontally, you first peel off the first and third sections and stick it to the clothing. In this case, the second and fourth sections of release paper remain on the adhesive surface. Next time you use it, peel off the second and fourth layers of release paper and stick it to your clothes. In this case, the first and third layers of release paper will remain on the adhesive surface. The adhesive on disposable hand warmers is consistently strong, so even half of the adhesive surface is sufficient to stick to clothing and maintain adhesion. Reducing the adhesive surface area by half would halve the damage to clothing, helping to extend the lifespan of garments. Depending on the adhesive strength of the adhesive surface, if it adheres to clothing using one-third or one-quarter of the adhesive surface, it can be divided into six or eight sections. In this case, further reduction in damage to clothing can be expected. [Brief explanation of the drawing]

[Figure 2] This is a drawing of the release paper of the present invention, divided vertically into four sections. [Figure 3] This is a drawing of the cross-shaped division of the release paper of the present invention. [Figure 4] This is a drawing of the X-shaped division of the release paper of the present invention. [Figure 5] This is a drawing of the eight divisions of the release paper of the present invention. [Figure 6] This is a drawing of the release paper of the present invention divided into six sections. [Modes for carrying out the invention]
[0008] The release paper (2) attached to the adhesive surface of the disposable hand warmer (1) is divided into 4, 6, or 8 sheets, but the number of sheets can be any odd number. Various division patterns are possible for the release paper (2). The divisions can be vertically divided into 4 or 6 sections, horizontally divided into 4 or 6 sections, or divided diagonally into 4 sections to form an "X" or a cross, or punched out in the shape of a circle or a square.
