Description

Gel nail sticker iron and iron tip {GEL NAIL STICKER IRON AND IRON TIP}

The present invention relates to a gel nail sticker iron and an iron tip used in gel nail stickers.

Nail art is a field of beauty art that is widely used not only by the younger generation but also by women of various ages, and has recently been used by men as well. Accordingly, various nail materials and design techniques that reflect the tastes of various consumers are being researched recently.

Conventional nail art mainly consisted of uniformly applying liquid nail polish of various colors to the fingernails (hereinafter used as a concept including toenails), but this liquid nail polish method was difficult to work with and took time to dry after application. It takes a lot of time and has the problem of poor durability.

Dry nail stickers were developed to overcome the problems of liquid nail polish. Since most dry nail stickers are films made from the same raw materials as liquid nail polish, there is a problem of poor durability after attachment and poor sustainability.

Artificial nails that are made of plastic or vinyl and are relatively durable have been developed, but they have the disadvantage of not being able to naturally fit on the nail and being easily separated due to poor adhesion due to their lack of flexibility and elasticity.

To compensate for these shortcomings, gel nails (ultraviolet gel nails) were developed in which liquid nail polish containing UV curing resin is applied to the nail and then cured using a UV curing machine. This method has many advantages, such as durability, but, like the early liquid nail polish, the process of applying it to the nail is difficult, and the process becomes more complicated when patterns of various shapes are included.

Recently, semi-cured gel nail stickers have been developed. These gel nail stickers have the advantage of being relatively better at adhering to artificial nails made of plastic or vinyl as they are attached in a semi-cured state. However, gel nail stickers in a semi-hardened state may harden when exposed to natural light during the manufacturing or distribution process, and in this case, there is a problem in that it is difficult to attach to the nail.

In addition, there is a problem that slight shrinkage of the sticker occurs during the photocuring process after attachment to the nail, creating a fine gap between the sticker and the nail, thereby weakening the adhesive strength. Moreover, moisture penetrates through these gaps, further weakening the adhesive strength. However, there is a problem that it causes nail damage such as nail fungus. Moreover, there is the inconvenience of having to use scissors individually to cut the gel nail stickers to fit the tip of the nail after attaching them to the nail.

The present invention aims to solve the problems of the conventional gel nail stickers described above.

The purpose of the present invention is to provide a gel nail sticker iron that can heat and soften the gel nail sticker before attaching it to the nail to increase adhesion and prevent a gap from forming between the sticker and the nail area.

Another object of the present invention is to provide a gel nail sticker iron that can be easily cut to fit the tip of the nail after attaching the gel nail sticker to the nail.

Another object of the present invention is to provide an iron tip used in the gel nail sticker iron.

In order to achieve the above object, according to one aspect of the present invention, a handle (10); An iron tip (20) coupled to one end of the handle (10) and used to heat and iron the gel nail sticker; A heater 30 provided inside the handle 10 to transfer heat to the iron tip 20; A gel nail sticker iron is provided, characterized in that it includes a control unit 40 that controls the heater 30.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Before explaining the invention, terms for nail parts related to gel nail stickers are first defined with reference to FIG. 1. In Figure 1, reference number 1 represents a finger (when referring to a toenail, it represents a toe), and reference number 7 represents a gel nail sticker. In this specification, reference numbers 2 to 6 are sequentially referred to as the nail body, nail tip, upper slough area, nail side, and crescent moon area.

As shown, the gel nail sticker iron according to this embodiment includes a handle 10, an iron tip 20, a heater 30, a control unit 40, an operation unit 50, and a temperature sensing unit ( 60).

The handle 10 is a part that the user holds with his hand when using the gel nail sticker iron of the present invention. The handle 10 may be made of a common insulating and insulating material such as plastic. The shape of the handle 10 may be cylindrical as shown in FIG. 2, but it is not limited thereto and may have various shapes that are comfortable for the user to hold by hand. Inside the handle 10, a space is formed where other components such as the heater 30, the control unit 40, and the temperature sensing unit 60 can be installed.

The iron tip 20 is coupled to one end of the handle 10 and serves to heat and iron the gel nail sticker (see reference number 7 in FIG. 1; reference numbers omitted below). The term ‘ironing’ here does not mean smoothing out wrinkles as if ironing clothes with a general clothing iron, but rather means softening the semi-hardened gel nail sticker, stretching it, pressing it, or doing other necessary processing. In other words, it is a general term for all operations performed using the iron tip (20) on gel nail stickers.

The material of the iron tip 20 may be a metal material commonly used in the iron industry, or insert silicone, in which a metal is inserted into silicone rubber, may be used. If the insert is made of silicone, it has the advantage of preventing burns.

The iron tip 20 includes a generally convex tip back portion 21 on the lower side, a generally concave tip inner surface portion 22 on the upper side on the opposite side, a tip distal end 24 at the tip, tip side portions 25 on both sides, and , and is composed of a coupling portion 27 at the rear end. The iron tip 20 has a certain thickness, and each corner that can come into contact with the skin around the nail is preferably processed to be round, such as the tip distal end 24 shown in FIG. 5.

The tip back part 21 is a part that is in direct contact with the gel nail sticker at the beginning of the nailing process, and is a part that receives heat from the heater 30 to heat and soften the gel nail sticker. In this embodiment, the tip back portion 21 has an overall convex shape, but its central area may have a flat shape to increase the contact area with the gel nail sticker.

The tip inner surface portion 22 is used to press the gel nail sticker attached to the nail as a whole, and has an overall concave shape to correspond to the curved surface of the nail body. According to this configuration, there is an advantage that the gel nail sticker can be pressed stably as a whole when the curved surface of the tip inner surface 22 matches the curved surface of the nail body.

A convex portion 23 may be formed in the central area of the tip inner surface portion 22 as shown in FIGS. 2 and 3. Since it is sufficient for the convex portion 23 to be relatively convex compared to the concave inner surface of the tip inner surface portion 22, not only does the upper surface protrude upward with respect to the horizontal plane, but also coincides with the horizontal plane or is lower than the horizontal plane. It can be included. According to this configuration, there is an advantage that the gel nail sticker can be partially pressed even when the curved surface of the tip inner surface 22 and the curved surface of the nail body do not match.

The tip end portion 24 is a part that contacts the gel nail sticker on the inside of the nail, that is, toward the stomach skin area, and serves to spread and press the gel nail sticker toward the stomach skin area. With this configuration, it is possible to prevent the gel nail sticker from lifting off the nail in the upper skin area.

In addition, the tip end portion 24 also serves to cut the outside of the nail, that is, the portion of the gel nail sticker protruding outside the tip of the nail, after the process of attaching the gel nail sticker to the nail is completed. Accordingly, you can easily cut gel nail stickers without using separate scissors. At this time, cutting is performed while pressing the gel nail sticker with the tip end portion 24, so that the gel nail sticker can be prevented from lifting off the tip of the nail.

The tip side portion 25 is a part that contacts the gel nail sticker on both sides of the nail, that is, the nail side, and serves to spread and press the gel nail sticker toward the nail side. With this configuration, it is possible to prevent the gel nail sticker from lifting off the nail at the side of the nail.

The coupling portion 27 extends from the neck portion 26 at the rear end of the iron tip 20, that is, opposite the tip end portion 24, and is detachably coupled to the handle 10. The end of the coupling portion 20 is connected to the heater 30 on the inside of the handle 10 and receives heat from the heater 30. 3 to 5 show a flat protrusion-shaped coupling portion 27, and a corresponding coupling groove (not shown) is formed in a corresponding portion of the handle 10. The coupling portion 27 and the coupling groove may be coupled by an interference fit method. The coupling portion 27 and the handle 10 can be coupled using various methods known in the technical field other than these methods.

The iron tip 20 having the above-described configuration can be provided in a plurality of types to suit various shapes of nails, that is, fingernails or toenails. Accordingly, any one iron tip 20 is attached to the handle 10. It can be used in selective combination. In this case, the iron tip 20 on which the above-described convex portion 23 is formed can be prepared separately from the iron tip 20 on which the convex portion 23 is not formed.

The heater 30 is provided inside the handle 10 and serves to transfer heat to the iron tip 20. The heater 30 can use a typical electric heater used in the iron field, and its configuration is widely known in the technical field, so detailed description is omitted.

The control unit 40 is provided inside the handle 10 and controls the entire ironing device, and in particular, controls the heater 30 and the display unit 70, which will be described later.

The operation unit 50 is provided on the outside of the handle 10 and includes an on-off unit 51 that turns the device on and off and a temperature control unit 52 that controls the temperature of the heater 30. . The on-off unit 51 and the temperature control unit 52 may be configured using a conventional push button method or various other methods known in the technical field.

The temperature sensing unit 60 is provided to contact the coupling portion 27 of the iron tip 20 on the inside of the handle 10, detects the temperature of the iron tip 20, and transmits the detected temperature information to the control unit 40. send. According to this temperature information, the control unit 40 can control the heater 30 and the display unit 70, which will be described later. The temperature sensing unit 60 can use a normal temperature sensor, and its configuration is widely known in the technical field, so detailed description is omitted.

The gel nail sticker iron according to this embodiment may further include a display unit 70 that displays the temperature detected by the temperature sensor 60. The display unit 70 may be disposed adjacent to the manipulation unit 50 on the outside of the handle 10 as shown in FIG. 2 . The display unit 70 may be configured in various ways known in the technical field, such as an LED lamp.

Among the configurations of this embodiment described above in the block diagram of FIG. 6, the heater 30 centered on the control unit 40, the on-off unit 51, the temperature control unit 52, the temperature detection unit 60, and the display unit 70. ) and power control relationships are schematically shown.

Power supply to the gel nail sticker iron according to this embodiment can be done through the USB port 80 as shown in FIG. 2, and of course, various methods known in the technical field can be used.

Meanwhile, in this embodiment, the temperature of the iron tip 20 is preferably adjusted in three stages: a preheating stage, a working stage, and a cutting stage.

The preheating step is a step of preheating the iron tip 20 to facilitate nailing work, and is preferably performed at approximately 25 to 40°C.

The work step is a nailing work step in which the gel nail sticker is heated to soften and attached to the nail, and is preferably performed at approximately 40 to 55°C. This takes into account the fact that if the heating temperature is lower than 40℃, the gel nail sticker will not be sufficiently softened, and if the heating temperature is higher than 55℃, there is a risk of burns.

The cutting step is a step of cutting the portion of the gel nail sticker that protrudes out of the tip of the nail after the process of attaching the gel nail sticker to the nail is completed. It is preferably performed at approximately 55 to 60°C to facilitate cutting. This takes into account the fact that if the temperature is higher than 60℃, the risk of burns is very high.

Here, the values that determine the temperature range are not mathematically exact, and are, of course, values that allow for some errors during work.

As the temperature of the iron tip 20 is divided into three stages, the preheating stage, the working stage, and the cutting stage, it is desirable that the display unit 70 is also configured to reflect the three stages. For example, the preheating step can be displayed in yellow, the heating step in red, and the cutting step in white.

Hereinafter, with reference to FIG. 7, the process of attaching a gel nail sticker to a fingernail using the gel nail sticker iron according to this embodiment will be described.

First, prepare for nailing work by removing the cuticle and loose skin near the top of the nail and the side of the nail in advance, and operate the heater 30 by manipulating the on-off part 51 and operating the temperature control part 52. The gel nail sticker is softened by pressing it with the tip back part 21 of the iron tip 20, where the temperature has passed through the preheating stage and reached the heating stage through manipulation (S1).

Next, use both hands to slightly stretch and spread the softened gel nail sticker according to the shape and length of the nail (S2).

Next, attach the gel nail sticker to the nail while maintaining balance on both sides from the top of the nail (S3).

Next, stretch and press the gel nail sticker to fit the upper skin area with the tip tip (24) (S4), and stretch and press the gel nail sticker to fit the side of the nail with the tip side (25) (S5). . At this time, steps S4 and S5 may be performed in a different order.

Next, press the entire nail body with the inner surface of the tip (22) so that the gel nail sticker is stably attached to the nail (S6). In this case, when the above-described convex portion 23 is formed on the tip inner surface portion 22, the convex portion 23 can be used to partially press.

Next, the temperature control unit 52 is operated to increase the temperature of the iron tip 20 to the cutting stage, and the gel nail sticker is cut to fit the tip of the nail using the tip end 24 (S7).

Next, the gel nail sticker is cured using a normal curing machine (S8). With this, attachment of the gel nail sticker is completed.

In the above, the present invention has been described in detail through examples and the accompanying drawings, but the technical idea of the present invention should be determined by the matters stated in the claims, and within the scope of the technical idea of the present invention. There may be various modifications and equivalent examples.
