Abstract

The present invention comprises a container portion for holding a dyeing liquid inside, and a coating portion formed at the opening of the container portion for applying the dyeing liquid inside the container portion to the scalp, wherein the coating portion is inserted into the opening of the container and has a discharge port on one side for discharging the dyeing liquid inside the container; a valve inserted into the inner part of the cap to open and close the discharge port of the cap through rotation to control the amount of dyeing liquid discharged from the container portion; a head inserted into the outer part of the cap to rotate the valve through rotation, discharges the dyeing liquid discharged from the discharge port of the cap onto the scalp through pumping, and applies the discharged dyeing liquid to the scalp to form dots; a joint connected between the valve and the head to transmit the rotational force of the head to the valve and enable the movement of the head during pumping; and a stopper inserted at the outer end of the inner part of the cap to prevent the head from detaching from the cap. By comprising the above, the present invention integrates a container for holding the dye solution and a coating part for applying the dye solution to the scalp, thereby enabling convenient use and facilitating easy scalp dyeing, while significantly reducing the dyeing time required. Furthermore, it prevents the dye solution adsorbed on the coating part from dripping down and contaminating clothing or the surroundings during the process of the coating part moving from the case to the scalp, which is a problem in conventional devices. Additionally, since the discharge of the dye solution can be blocked and the discharge volume arbitrarily controlled through the valve of the coating part, the user can adjust the amount of dye solution used as desired. Moreover, the dye solution is easily dispensed onto the scalp through the pumping function of the head, and by applying the dispensed dye solution in a dot-like pattern, uniform application of the dye solution is possible, thereby maximizing the dyeing effect. Furthermore, the simple structure reduces costs, enabling mass production, and the ease of assembly and disassembly for cleaning ensures high accessibility for consumers.

Description

Stamper for scalp dyeing The present invention relates to a scalp dyeing stamper, and more specifically, to a scalp dyeing stamper capable of easily applying a dyeing solution to a scalp with insufficient hair. The causes of hair loss can be broadly divided into internal and external environmental factors. Internal factors include genetics, hormonal imbalances, stress, and diseases, while external environmental factors include scalp uncleanliness, environmental pollution, and chemical treatments. The recent surge in the young population experiencing hair loss is often caused by exposure to harmful environments, work stress, and poor dietary habits; therefore, it is necessary to address the issue by paying attention to basic nutrition and hair care in daily life, or by using hair loss medication for appropriate treatment in the early stages. Methods for treating or improving hair loss include non-surgical drug therapy, surgical hair transplantation, wigs, and scalp covering. In particular, scalp covering methods include hair fibers and scalp micropigmentation (SMP). However, hair fibers cause significant inconvenience in daily life due to dust scattering, and people inevitably hesitate to undergo SMP due to concerns about health and hygiene, illegal procedures, high costs, and the burden of pain. Consequently, scalp dyeing is gaining popularity as an alternative to hair fibers or scalp micropigmentation, as it minimizes the burden associated with scalp coverage. Scalp dyeing allows for the natural concealment of hairless areas by applying a dyeing solution to the scalp where hair is scarce, and the device used for such scalp dyeing is disclosed in detail as prior art in Korean Registered Utility Model Publication No. 20-0495025. According to the prior art described above, a conventional scalp dyeing device is configured with a case containing a dyeing liquid on one side and a coating part that comes into contact with the scalp on the other side, and the method of use is to put the dyeing liquid into the case, then place the coating part into the case so that the coating part absorbs the dyeing liquid, and then apply the dye by contacting the coating part with the absorbed dye to the scalp. However, conventional scalp dyeing devices had the following problems during use because the coating part and the case were configured separately. First, since the coating part had to be inserted into the case and adhered multiple times, it was cumbersome and time-consuming, causing significant inconvenience in use. Second, as the coating part moved from the case to the scalp, the dye liquid adhered to the coating part often dripped down, contaminating clothes or the surrounding area. Third, if a part of the coating part failed to adhere to the dye liquid contained in the case, the dye liquid was not applied evenly to the scalp, resulting in a high likelihood of uneven dyeing.
