  The present invention relates to a hair removal apparatus and a hair removal method used for removing unwanted hair of a body for the purpose of beauty and the like.

  Conventionally, as a method for removing unwanted hair on the body such as arms, armpits, legs, etc., a method is known in which a pressure-sensitive adhesive sheet having a strong adhesive force is applied to the skin and then the adhesive sheet is peeled off together with the unwanted hair. . However, this hair removal method has a possibility of peeling off to the stratum corneum constituting the surface layer of the skin, and has a problem from the viewpoint of skin care and has a defect that pain is accompanied at the time of hair removal.

  Therefore, the following hair removal pressure-sensitive adhesive sheet has been proposed as a method of leaving only the dead hair while leaving the stratum corneum. This hair removal pressure-sensitive adhesive sheet is composed of two layers: a film layer with weak adhesive strength that adheres to the skin when attached to the skin, and a hair removal agent layer that adheres the attached unwanted hair with strong adhesive strength. Yes.

Since the stratum corneum is not in direct contact with the strong depilatory agent layer, the pressure-sensitive adhesive sheet for hair removal having such a structure can leave only the dead hair leaving the stratum corneum when peeled off ( Patent Document 1).

  Further, the present invention is a hair removal method for removing unwanted hair using the hair removal apparatus according to any one of claims 1 to 3, wherein the high frequency current output from the high frequency transmission circuit is applied to the adhesive sheet adhered to a treatment site. The present invention provides a hair removal method characterized in that the adhesive sheet is peeled off with unwanted hair after a predetermined time has passed.

A hair removal apparatus according to the present invention is a hair removal apparatus comprising an apparatus main body having at least a high-frequency transmission circuit, and an adhesive sheet in which a conductive layer and an adhesive layer are laminated on the surface of a sheet material having a required width, The apparatus body includes a lead wire that sends out a high-frequency current output from the high-frequency transmission circuit, and the adhesive sheet includes an electrode to which the lead wire can be attached and detached, and the electrode and the conductive layer are in contact with each other. As a result, a high-frequency current propagates to the hair root tissue through the adhesive sheet adhered to the treatment site, and this high-frequency current is converted into heat energy inside the hair root tissue to generate heat and destroy the hair root tissue. Thereafter, a wide range of hair removal treatment can be efficiently performed by peeling the adhesive sheet together with the dead hair.
And when pulling out unwanted hair, the hair root is destroyed, so the pain when peeling off is alleviated and there is almost no residual hair left.
Furthermore, since the conductive layer is formed on the upper part of the pressure-sensitive adhesive layer, there are various excellent effects that a high-frequency current flows throughout the pressure-sensitive adhesive layer and efficiently propagates to the hair root tissue.

  Then, the conductive layer contains metal powder or carbon, so that the conductivity becomes good, and the high-frequency current is efficiently propagated to the hair root tissue, and the hair root tissue is destroyed.

  Furthermore, since collagen is added to the pressure-sensitive adhesive layer, the collagen functions to activate cell functions and enhance immunity. Therefore, it is effective for skin rejuvenation at the same time as hair removal treatment. Has an effect.

  The hair removal method according to the present invention is a hair removal method for removing unwanted hair using the hair removal apparatus according to any one of claims 1 to 3, wherein the hair removal method outputs to the pressure-sensitive adhesive sheet adhered to a treatment site by the high-frequency transmission circuit. The high frequency current is applied, and after a predetermined time has elapsed, the adhesive sheet is peeled off with the unwanted hair, whereby the high frequency current is propagated to the hair root tissue through the adhesive sheet adhered to the treatment site, and this high frequency current is transferred to the hair root tissue. It is converted into heat energy inside and generates heat and destroys the root tissue. After that, by peeling off the adhesive sheet together with the dead hair, there is an excellent effect that a wide range of hair removal treatment can be efficiently performed.

  The purpose of carrying out a wide range of hair removal treatment with low pain and efficiency was realized by using an adhesive sheet that can propagate a high-frequency current to the treatment site. That is, a high-frequency current is propagated through the pressure-sensitive adhesive sheet to the hair root tissue to destroy a wide range of hair root tissues at once, and the pressure-sensitive adhesive sheet is peeled off together with the dead hair after a predetermined time.

  Next, embodiments of the present invention will be described with reference to the drawings. First, FIG. 1 is a block diagram of a hair removal apparatus according to the present invention, in which reference numeral 10 denotes an apparatus main body, 11 denotes a power supply circuit, 12 denotes a high-frequency transmission circuit, 13 denotes a lead wire, and 14 denotes an adhesive sheet.

  The power supply circuit 11 is a circuit for stably supplying necessary power, is configured to be connected to a commercial power supply (not shown), and is connected to the high-frequency transmission circuit 12. The high-frequency transmission circuit 12 is a circuit for transmitting and supplying a high-frequency current, and a lead wire 13 is connected to the high-frequency transmission circuit 12. The lead wire 13 is configured to be detachably connected to the adhesive sheet 14. Therefore, when an output switch (not shown) is turned on, a high-frequency current output from the high-frequency transmission circuit 12 flows through the lead wire 13 and is applied to the adhesive sheet 14.

  The apparatus main body 10 is formed in a required case, and the power supply circuit 11 and the high-frequency transmission circuit 12 are housed inside the apparatus main body 10. An output switch (not shown) is provided at a predetermined position of the apparatus main body 10.

  As shown in FIGS. 2 and 3, a hook-shaped fitting member 15 is provided at one end of the lead wire 13, and a recess 15 a is formed in the lower portion of the fitting member 15. And it is the structure which can connect the fitting member 15 to the electrode 16 of the adhesive sheet 14 mentioned later so that attachment or detachment is possible.

The pressure-sensitive adhesive sheet 14 is formed in various sizes and shapes in accordance with the body part to be removed. If an example of the shape is illustrated, it is formed in a rectangular shape as shown in FIG.
Further, as shown in FIG. 3, the pressure-sensitive adhesive sheet 14 includes a synthetic resin sheet material 17, a conductive layer 18a and a pressure-sensitive adhesive layer 18b laminated on the surface of the sheet material 17, and a surface of the pressure-sensitive adhesive layer 18b. It is comprised from the release paper 19 affixed on the, and the electrode 16 is provided in the edge part.

  The conductive layer 18 a is formed of a conductive material obtained by mixing an appropriate resin agent in a material having good conductivity, for example, metal powder such as silver powder, gold powder, copper powder, or carbon, and this is applied to the surface of the sheet material 17. The desired thickness is applied by a predetermined means such as coating or printing. A pressure-sensitive adhesive layer 18b having a required thickness is formed below the conductive layer 18a.

  As the pressure-sensitive adhesive constituting the pressure-sensitive adhesive layer 18b, a conventionally known pressure-sensitive adhesive having relatively good conductivity is used. As an example of the component of the pressure-sensitive adhesive, an acrylic type mainly composed of polyacrylic acid resin, a vinyl ether type mainly composed of vinyl ethylene ether, and an acrylic type mainly composed of polybutyl acrylate. Various components such as those and other silicone-based ones may be used. In short, it is only necessary to use an adhesive that has a component capable of firmly adhering the dead hair of the body.

  Moreover, you may mix | blend a required amount of collagen in the said component of the adhesive layer 18b. In this case, since collagen functions to activate cell functions and enhance immunity, it is effective for activating the skin where the adhesive sheet 14 is adhered, that is, rejuvenating the skin.

  As shown in FIG. 3, the electrode 16 has a fitting bulge 16 a that slightly bulges, an upper flange 16 b, and a lower flange 16 c formed integrally. The concave portion 15a of the fitting member 15 can be detachably connected to the fitting convex portion 16a. Further, the sheet material 17 is sandwiched between the upper flange portion 16b and the lower flange portion 16c, and the lower flange portion 16c is in contact with the conductive layer 18a.

  Next, a hair removal method using the hair removal apparatus configured as described above will be described. First, the release paper 19 of the pressure-sensitive adhesive sheet 14 is peeled off, and is adhered in a state of being in close contact with a part of the body where hair is to be removed. At this time, the unwanted hair is firmly adhered to the adhesive layer 18b.

  When the output switch is turned on, a high-frequency current is output from the high-frequency transmission circuit 12, flows through the lead wire 13, is sent to the electrode 16, and is further transmitted to the conductive layer 18a via the lower flange portion 16c. It is transmitted to the pressure-sensitive adhesive layer 18b. At this time, since the conductive layer 18a exists above the adhesive layer 18b, a high-frequency current flows over the entire adhesive layer 18b.

  Further, the high-frequency current applied to the pressure-sensitive adhesive layer 18b propagates to the hair root tissue, and is converted into heat energy therein to generate heat and destroy the hair root tissue. As an example of the high-frequency current, it is desirable to pass a current of 50 to 60 volts at an output of 27.120 megahertz. After about 3 to 10 minutes have passed in this state, the pressure-sensitive adhesive sheet 14 is peeled off together with the dead hair. At this time, since the hair root has already been destroyed, there is little pain when the adhesive sheet 14 is peeled off, and there is almost no residual hair remaining.

  In addition, since the adhesive sheet 14 is disposable, it may be discarded as it is after use, and post-processing is simple. Further, when the hair removal apparatus is used next time, a new pressure-sensitive adhesive sheet 14 may be set, and the hair removal treatment can always be performed in a clean state.

  The hair removal apparatus and the hair removal method of the present invention can perform a hair removal treatment on a part of the body, such as an arm, an armpit, a leg, or a bikini line, which is anxious about unwanted hair.

It is a block diagram of the hair removal apparatus which concerns on this invention. It is a perspective view of the adhesive sheet of the hair removal apparatus which concerns on this invention.
