DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the adhesive sheet for hair removal of the present invention will be described below with reference to the drawings. First, an embodiment of the present invention (first invention) described in claim 1 will be described with reference to FIGS. Here, FIG. 1 is a perspective view showing a hair removal adhesive sheet according to the first embodiment of the present invention described in claim 1, and FIG. 2 (a) is a cross-sectional view taken along line AA of FIG. FIG. 2B is a sectional view taken along line BB of FIG. 1. 3A and 3B are explanatory diagrams illustrating a use state of the depilation adhesive sheet of FIG. 1, wherein FIG. 3A illustrates a state in which a support sheet is adhered to a depilation portion, and FIG. FIG. 3 is a diagram showing a state in which the hair removal tool 6 is used to remove the hair.

The adhesive sheet 1 for depilation of the first embodiment is an adhesive sheet for depilation in which a release sheet 3 is coated on one surface of a support sheet 2 having an adhesive layer 2a on one surface. The adhesive sheet 2 is provided with a slit 4 so that the support sheet 2 can be partially peeled off from the depilated portion after the support sheet 2 is adhered to the depilated portion via the adhesive layer 2a. Is an adhesive force that does not accompany hair removal when peeled off from the hair removal target portion.

As shown in FIG. 1, the depilatory adhesive sheet 1 is a substantially rectangular and flat sheet, and comprises a support sheet 2 having an adhesive layer 2a on one surface, and the adhesive layer 2a of the support sheet 2. And a release paper 3 to be coated.

The support sheet 2 is formed by forming the adhesive layer 2a on one surface of a sheet-like material made of an arbitrary material such as paper or a synthetic resin film. The adhesive strength of the adhesive layer 2a is such that when the support sheet 2 is adhered to the depilated portion via the adhesive layer, it does not fall naturally from the depilated portion, but substantially when the support sheet 2 is peeled off from the depilated portion. It is preferable that the adhesive has a low adhesive strength that does not involve hair removal, and that it does not easily peel off when the hair removal tool is applied to the exposed portion. The pressure-sensitive adhesive layer 2a is formed by applying a predetermined pressure-sensitive adhesive to one surface of the support sheet 2 so as to obtain such a pressure-sensitive adhesive strength. The above-mentioned hair removal part means a skin surface of a desired part where hair removal is desired, and examples thereof include a skin surface such as an arm, a leg, a face, an armpit, and a bikini line.

Examples of the material of the pressure-sensitive adhesive constituting the pressure-sensitive adhesive layer 2a include rubber-based, acrylic, vinyl ether-based, and silicone-based materials.
For example, in addition to natural rubber, styrene / butadiene copolymer rubber, polyisobutylene, isobutylene / isoprene copolymer rubber (butyl rubber), thermoplastic rubber (styrene / isoprene / styrene block copolymer, styrene / butadiene / styrene block copolymer, chloroprene rubber, Butadiene / acrylonitrile block copolymer). Examples of the acrylic material include polybutyl acrylate, polyoctyl acrylate (mainly 2-ethylhexyl), and copolymers prepared by selecting an appropriate copolymer based on these, and the like.
Examples of the vinyl ether-based material include polymers such as vinyl ethyl ether, vinyl butyl ether, and vinyl isobutyl ether. Examples of the silicone-based material include a polymer mainly composed of a polydimethylsiloxane polymer.

The materials for these pressure-sensitive adhesives are generally provided in the form of a solution or an emulsion, but can also be prepared by a heat calendering treatment or a hot melt treatment.
Among the above-mentioned pressure-sensitive adhesives, acrylic pressure-sensitive adhesives are particularly preferred. If acrylic pressure-sensitive adhesives are used, a highly safe pressure-sensitive adhesive sheet for depilation with little irritation to the skin can be obtained.

The release paper 3 covers the adhesive layer 2a of the support sheet 2 and prevents the adhesive 2a from decreasing before the use of the adhesive sheet 1 for hair removal. It is for improving the preservability, transportability and the like of the pressure-sensitive adhesive sheet 1 for use. The adhesive layer 2a of the release paper 3
The release surface is subjected to a release treatment so that the release paper 3 is easily released from the adhesive layer 2. The release treatment is not particularly limited as long as the release paper 3 can be released from the pressure-sensitive adhesive layer 2a, and includes various conventionally known release treatments. Further, the release paper 3 may be one that can be released by selecting a material for forming the release paper 3 without using a release process.

The support sheet 2 in the depilatory adhesive sheet 1 of the first embodiment has a plurality of slits 4.
Are provided in parallel with each other. These slits 4
Is that the support sheet 2 can be partially peeled off from the part to be depilated after the support sheet 2 is adhered to the part to be depilated via the above-mentioned adhesive layer 2a. The support sheet 2 adhered to the depilation portion can be peeled off for each portion sandwiched between the slits 4 (hereinafter, sometimes referred to as a narrow band portion 5). Incidentally, the reason why the slits 4 are provided in parallel with each other in the adhesive sheet for hair removal of the first embodiment is that it is simple in process, and
This is because partial peeling of the support sheet 2 becomes extremely easy.

Each of the slits 4 is provided such that an interval H between adjacent slits (see FIG. 2) is 1 to 30 mm, more preferably 4 to 15 mm. When the interval between the slits is less than 1 mm, it is difficult to peel off each of the strip-shaped portions, and at the time of a hair removal operation to be described later, the range of hair removal at one time becomes too small, and the efficiency of the hair removal process is reduced. And so on. On the other hand, if the distance between the slits is more than 30 mm, the range of hair removal at one time becomes excessive, so that the effect of reducing pain cannot be expected much.

As shown in FIG. 2A, each slit 4 is provided so as to reach the adhesive layer 2a. When the slits 4 are provided so as to reach the adhesive layer 2a in this manner, it is easy to peel off each of the strip-shaped portions 5, and workability is improved. However, the slit is the adhesive layer 2
Even if it does not reach a, the slit does not need to reach the adhesive layer 2a if the support layer has slits so that the support sheet can be peeled off while the adhesive layer is broken when the support sheet is peeled off. As shown in FIG. 1, each of the slits 4 is provided so as to extend from one end to the other end of the support sheet 2, and the strip-shaped portions 5 can be peeled off from either end. I can do it.

Next, a method for using the pressure-sensitive adhesive sheet 1 for hair removal, that is, a hair removal method according to an embodiment of the present invention will be described. First, the release paper 3 is peeled off to expose the adhesive layer 2a. Then, as shown in FIG. 3 (a), the adhesive layer 2a
To make the support sheet 2 adhere to the skin surface. Next, the support sheet 2 is peeled off at a portion divided by the slits 4, that is, one (or a plurality of strips) of the strip-shaped portions 5 in some cases. Then, as shown in FIG. 3B, the part exposed by the peeling is subjected to a hair removal treatment with a hair removal tool 6 such as a commercially available electric hair removal tool. After performing hair removal treatment on the first exposed portion, the first strip-shaped portion 5
Then, the next strip-like portion 5 is peeled off. As a result, the skin surface that has not been subjected to the hair removal treatment is newly exposed, and the hair removal treatment is performed on the exposed portion by the hair removal tool 6 in the same manner as described above. The hair removal device 6 shown in FIG. 3 is a commercially available electric hair removal device, a hair removal device having a plurality of clam-like holding portions that open and close with rotation at the tip thereof, and holding the waste hair by the holding portions. It is a mechanism of pulling out while pulling.

In this manner, by partially repeating the peeling of the support sheet 2 and the hair removal treatment of the exposed portion by the hair removal tool, the entire depilated portion to which the support sheet 2 is adhered is removed. Can be surely removed one by one. According to this hair removal method, the support sheet 2 is partially peeled off, and only the exposed portion is treated, so that the range of the hair removal treatment at one time is limited. The pain associated with the processing is significantly reduced as compared with the case where the processing is performed. In addition, the support sheet 2 in the pressure-sensitive adhesive sheet 1 for depilation of the present embodiment includes:
Since it becomes a form adapted to the shape of the hair removal part and adheres to the hair removal part, a series of hair removal treatments by such a method can be easily performed.

The order of the partial peeling of the support sheet 2 is not particularly limited.
May be peeled in order from one end to the other end in a direction perpendicular to the direction, or may be peeled in order from the center to the end. In addition, the user can perform the peeling in a desired order that has been learned through experience and is considered to be the most pain-reducing.

Next, one embodiment (referred to as a second embodiment) of the present invention (second invention) according to claim 3 will be described with reference to FIG.
This will be described with reference to FIG. Here, FIG. 4 is a diagram showing the pressure-sensitive adhesive sheet 10 for hair removal according to the present embodiment, wherein FIG. 4 (a) is a perspective view, and FIG. 4 (b) is a cross-sectional view taken along line CC of FIG. 4 (a). FIG. The adhesive sheet 10 for depilation of the second embodiment has an adhesive layer 2
