Description

Cosmetic container containing a subcutaneously penetrating skin stimulator that minimizes skin irritation}

The present invention relates to a cosmetic container including a subcutaneous penetration type skin stimulator that minimizes skin irritation.

The dermis, which forms wrinkles on the skin, constitutes the lowest layer of the epidermis, and is composed of a thicker layer than the epidermis, with a thickness of about 0.7 mm to 4 mm. The dermal layer contains collagen, and as aging progresses, the amount of collagen decreases, resulting in dry skin or wrinkles, resulting in reduced skin elasticity.

In order to generate such collagen, a cosmetic solution containing nutrients such as vitamin C or peptide is applied to the skin or sprayed to increase skin elasticity.

However, the amount of nutrients in the cosmetic solution passing through the stratum corneum of the skin is less than 0.3% of the total content, and the remaining 99.7% does not pass through the outermost sebum of the skin, remaining on the skin or drying up.

Conventionally, a roller having protrusions for skin penetration has been used. At the same time as the projections penetrate the skin, the cosmetic solution containing nutrients penetrates into the dermis, and when the skin is finely wounded, collagen is naturally produced by the skin's own natural healing power, so the skin can be regenerated. can That is, it is possible to reduce aged skin by inducing natural healing collagen production, such as laser peeling or peeling, without damaging the epidermal layer.

Recently, microneedle technology has been developed and used as a pharmaceutical, medical, or cosmetic substance delivery device. As a prior art disclosing microneedle technology, there is a 'microneedle patch and microneedle system' of Korean Patent Publication No. 10-2021-0029581. It is a technology that applies microneedles to patches. Specifically, the microneedles are configured to include a plurality of microneedles that are individualized from each other and have upper and lower portions and a water-soluble base layer bonded to the plurality of microneedles to two-dimensionally arrange the plurality of microneedles. When applied to the skin, moisture is supplied to the water-soluble base layer, so that the water-soluble base layer is removed and the plurality of two-dimensionally arranged microneedles are individualized.

However, the prior art does not disclose a configuration for effectively injecting a cosmetic solution into the skin using a needle as a structure for individualization of microneedles. As described above, when the cosmetic solution does not penetrate into the skin, most of the bar is ineffective, and thus, a structure that maximizes the penetration amount of the cosmetic solution into the skin is required.

Hereinafter, the present invention will be described in detail through the accompanying drawings and examples. A detailed description thereof has been omitted.

In addition, terms to be described later are terms defined in consideration of functions in the present invention, which may vary according to the intention or custom of a user or operator. Therefore, the definition should be made based on the contents throughout this specification.

First, the skin stimulator according to the present invention strikes the end of the skin such as the face, and is configured to penetrate a cosmetic solution containing nutrients such as collagen and vitamin C while entering a plurality of sharp needles such as needles into the dermis. do. For the convenience of the user, it is formed in a size that can be gripped by hand.

The fluid receptor 10 is a size that can be gripped by hand, and a cosmetic solution containing various nutrients is stored therein. The fluid container 10 is formed in a cylindrical shape with an open top so as to be discharged through the fluid discharge hole 11 at the top when it is tilted or pressurized inward.

A cap module 50 capable of covering the housing 20 may be formed above the fluid container 10 (see FIG. 10). The upper part of the fluid container 10 in which the fluid discharge hole 11 is formed has a smaller diameter than the body of the fluid container 10, and a housing coupling groove 13 into which the lower portion of the housing 20 is fitted is formed around the circumference. .

At this time, the lower part of the housing 20 has a smaller diameter than the upper part, and a cross section protrudes in an 'L' shape from the outer circumferential surface of the lower part of the housing 20, so that the lower surface of the housing 20 is in close contact. The lower part of the housing 20 is formed to have a smaller diameter than the upper part, so that the lower part of the housing 20 is fitted into the upper part of the receptor 10.

On the other hand, a fitting protrusion 23 is formed on the lower inner circumferential surface of the housing 20 and closely fixed to the upper outer circumferential surface of the fluid container 10 .

The needle plate 40 is formed in a disk shape. Although FIGS. 1 and 2 illustrate that the needle plate 40 has a flat shape as an example, the needle plate 40 may be formed to have a predetermined curvature. Since a person's face is not flat and has curves, the needle plate 40 formed in a hemispherical shape may be more effective than a flat shape. At this time, the user may be guided to use the fluid container 10 while rubbing it up and down or left and right while holding the fluid container 10 .

A fluid discharge hole 31 is formed in the center of the flow path plate 30, through which the cosmetic solution discharged along the fluid discharge hole 11 and the fluid transfer path 21 moves, and the cosmetic solution moves to the fluid transfer groove 32. will do On the other hand, a plurality of needles 41 are radially formed on the needle plate 40, and the cosmetic solution discharged to the fluid moving groove 32 may be discharged to the outside through the fluid passage hole 42.

With this structure, the cosmetic solution is discharged through the fluid through hole 42 adjacent to the needle 41 penetrating into the skin, and the cosmetic solution is easily injected into the skin so that the number of taps on the skin is relatively small, and the cosmetic solution penetrates the skin efficiently. can increase

A plate groove 33 in which the needle plate 40 is seated is formed on the upper surface of the flow path plate 30, and the circumference and upper portion of the flow path plate 30 and the needle plate 40 are formed around the housing 20. An enclosing separation prevention sphere 24 is formed. Accordingly, the flow path plate 30 on which the needle plate 40 is seated may not be separated from the seating groove 22 .

With this structure, the needle plate 40 in which the single flow path plate 30 and the needle 41 are integrally formed is fixed to the housing 20 so that the overall structure is very simple, and thus manufacturability can be increased, and manufacturing cost can be increased. You can also save money.

Hereinafter, a second embodiment of the needle plate applied to the skin stimulator of the present invention will be described with reference to FIGS. 3 to 7. For convenience of description, a description overlapping with that of the first embodiment will be omitted, and description will focus on differences.

The needle plate 640 of the second embodiment is different from the needle plate of the first embodiment in that the peripheral passage portion 643 surrounding the needle body 6412 is provided.

The needle plate 640 includes a base portion 645 formed in a disc shape, and has a structure in which a plurality of needles 641 are formed on the base portion 645 . Here, the needle 641 may have a radial shape. The peripheral passage part 643 is formed in the base part 645 and is formed for each needle 641 .

Referring to FIG. 4 , the peripheral passage part 643 surrounds the needle body 6412 and is configured to inject a cosmetic solution into the skin from the outside of the needle body 6412 . The above-described needle flow path portion 413 is located inside the needle 41, and has a structure for supplying a cosmetic solution through a fluid through hole 411 formed in the needle 41, but the second embodiment is a needle flow path portion 6413 ), as well as a structure for supplying the cosmetic solution through the peripheral passage portion 643.

The cosmetic solution supplied through the peripheral passage part 643 may be supplied along the outer circumferential surface of the needle body 6412. The needle body 6412 is formed in a horn shape, and is configured to flow along the outer circumferential surface of the horn.

Since the needle passage part 6413 is configured in a horn shape, the discharge pressure of the cosmetic solution can be increased. When the shape of the needle passage part 6413 is formed to correspond to the shape of the needle body 6412, manufacturing may be facilitated. When the needle 641 is extruded and the fluid passage hole 6411 is punched at the same time, it is most advantageous to configure the needle flow passage 6413 in a shape corresponding to the shape of the needle body 6412. .

The peripheral flow path portion 643 is configured to surround the needle body 6412, and has a structure in which the flow path is concentrated on the needle body 6412. It is not simply a structure in which the flow path is disposed between the needle bodies 6412, but a structure for concentrating on the needle bodies 6412 and flowing along the outer circumferential surface of the needle bodies 6412.

Depending on the size of the needle 641, it may vary, but the needle 641 may be configured in a replaceable form. That is, in FIG. 12, the cone-shaped needle body 6412 is applied, but a needle body of a different shape, such as a polygonal pyramid or a whirlwind cone, may be applied.

Referring to FIG. 5 , various forms of the peripheral passage part 643 will be described.

5(a) shows a concentric circle-shaped peripheral passage portion 643a, (b) shows a star-shaped peripheral passage portion 643b, and (c) shows a square-shaped peripheral passage portion 643c. , and (d) shows the peripheral passage portion 643d in the form of a combination of unit semicircles.

Among them, (b) and (d) of FIG. 5 will be described. All of these are structures in which unit shapes repeat and surround the needle body 6412. 5(b) is a structure in which triangles are combined, and has a star shape as a whole. 5(d) shows a structure in which semicircles are combined. Of course, a flower shape may be formed by combining figures having a predetermined curvature rather than a semicircle.

Here, the preset shape of the peripheral passage portion 643 is formed so that the horizontal cross-sectional area gradually increases as it is closer to the needle body 6412 based on the horizontal cross-section. The fluid discharged from the peripheral passage part 643 is supplied while flowing along the outer circumferential surface of the needle body 6412, and it is preferable that the horizontal cross-sectional area of the adjacent side of the needle body 6412 is maximized. That is, by forming as described above, the injection efficiency of the fluid can be maximized.

Referring to FIGS. 6 and 7 , a vertical section of the peripheral flow path portion 643 will be described in detail. The peripheral passage part 643 may have a straight vertical section (refer to FIG. 12(b) ), but may be formed in a horn shape rather than a straight line in consideration of fluid supply efficiency. By forming the peripheral flow path portion 643 in a horn shape, it is possible to maximize the discharge pressure of the fluid and smoothly supply it to the skin.

A vertical cross section of the peripheral passage portion 643 may be divided into a first side surface 643b adjacent to the needle passage portion 6413 and a second side surface 643a opposite to the first side surface 643b. In this case, the slopes of the first side surface 643b and the second side surface 643a may be formed to be different from each other. As described above, the fluid discharged through the peripheral passage portion 643 is supplied while flowing along the outer circumferential surface of the needle body 6412 to have a predetermined direction.

Specifically, by increasing the inclination of the first side surface 643b and decreasing the inclination of the second side surface 643a, the fluid discharge direction can be guided toward the outer circumferential surface of the needle body 6412. Referring to FIG. 15, it is a structure in which 2 is larger than 1. Since the first side surface 643b, which is the second side, has a relatively small resistance to hinder the flow of fluid, the fluid discharged through the peripheral passage part 643 may be deflected toward the second side surface 643a.

Meanwhile, the needle plate 640 of the skin stimulator according to the present invention can be manufactured by the following method. The method includes steps S110 to S130.

Step S110 is a step of preparing the base part 645. The base part 645 is preferably composed of a metal plate having a predetermined thickness. Extrusion and perforation are performed, and it is preferable that the material has a predetermined rigidity and is suitable for extrusion and perforation.

Step (S120) is a step of forming the needle 641 of the base portion 645 by using an extruder, forming a fluid through hole 6411 at the tip of the needle 641 and surrounding the needle 641. This is a step of perforating the peripheral flow passage part 643. The position of the fluid through hole 6411 and the perforated hole of the peripheral passage part 643 may vary depending on their shapes.

Step S130 is a step of separating the base part 645 from the extruder. That is, it is a step to be finally completed. At this time, handles 644a and 644b may be formed on one side of the edge of the base portion 645 .

In the present invention, the above embodiment is an example, and the present invention is not limited thereto. Anything that has substantially the same configuration as the technical concept described in the claims of the present invention and achieves the same operational effect is included in the technical scope of the present invention.
