Description

Skin stimulator that increases skin penetration of cosmetics

The present invention relates to a skin stimulator that increases the penetration of cosmetics into the skin.

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.

Terms used herein, including technical or scientific terms, may have the same meaning as commonly understood by one of ordinary skill in the art described herein.

Among the terms used herein, terms defined in a general dictionary may be interpreted as having the same or similar meaning as the meaning in the context of the related art, and unless explicitly defined herein, they are not interpreted in an ideal or excessively formal meaning. don't In some cases, even terms defined herein cannot be interpreted to exclude embodiments of the present application.

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 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 by hitting the end of the skin such as the face. 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. 14). 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.

First embodiment of needle plate

Hereinafter, a first embodiment of the needle plate 40 applied to the skin stimulator of the present invention will be described with reference to FIGS. 3 to 6.

Figure 3 is a perspective view of a first embodiment of a needle plate of the skin stimulator according to the present invention, Figures 4 and 5 are cross-sectional views showing a cross section of the needle plate of the skin stimulator according to the present invention, Figure 6 is a cross-sectional view of the needle plate according to the present invention This is a plan view of the first embodiment of the needle plate of the skin stimulator according to the present invention.

In the needle plate 40 of the present invention, at least one needle 41 protrudes from the body surface 45 and is positioned on the upper part of the flow path plate 30 so that the needle 41 is drawn into the skin. At this time, the needle plate 40 includes a fluid through hole 411 communicating with the fluid discharge hole 31, and the fluid through hole 411 covers a part of the needle 41 and a part of the needle plate body surface 45. It consists of an area that includes all

Referring first to FIG. 6 , the fluid through hole 411 is composed of a region including both the needle 41 and the body surface 45 . That is, it can be understood as an area that spans the inclined surface of the needle 41 and the main body surface 45 . Compared to the second embodiment to be described later, the first embodiment exhibits an effect of allowing the fluid to be drawn into the human body more smoothly.

This is because when the fluid through-hole 411 is formed at the tip of the needle 41, a strong pressure is required for fluid to be drawn into the skin, and if the pressure is not reached, the drawing effect may be reduced.

In the first embodiment, a fluid through hole 411 is formed at a part farthest from the tip of the needle 41, and a part of the fluid through hole 411 is formed so that it can enter the skin, so that fluid can enter. efficiency can be maximized.

Referring to Figures 3 and 6, the needle 41 may be configured in the shape of a quadrangular pyramid. This is an exemplary shape of the needle 41, and may be composed of other types of horns. The inside of the needle 41 is provided with a needle passage portion 413 communicating with the fluid discharge hole 31 (see Figs. 4 and 5). The needle passage portion 413 may be divided into an upper needle passage portion 413a and a lower needle passage portion 413b. Since the diameter of the upper needle passage portion 413a is larger than that of the lower needle passage portion 413b, the pressure of the fluid discharged from the upper needle passage portion 413a may be increased.

Referring to FIG. 2 together, a flow path plate 30 may be positioned below the lower needle flow path portion 413b. As described above, the flow plate 30 is provided with a plate groove 33. The plate groove 33 is formed in a radial shape, extending outward from the center of the plate groove 33, and this radial groove (fluid movement groove 32) is configured to communicate with the needle passage portion 413. .

The needle plate main body surface 45 is formed in a disk shape, and the needles 41 may be arranged symmetrically with respect to an imaginary boundary line passing through the central point of the needle plate main body surface 45 . At this time, the fluid through-holes 411 are arranged to face each other symmetrically around the virtual boundary line. That is, based on the virtual boundary line, the needle 41 and each fluid through hole 411 are all arranged symmetrically.

When the needle 41 group disposed on the outermost side of the needle plate body surface 45 is referred to as a first stage group, and the needle 41 group closest to the imaginary boundary is referred to as an N-stage group, in the first stage group The number of needles 41 is arranged to increase toward the Nth stage group. That is, the number of needles 41 is maximum at a position adjacent to the virtual boundary line, and the number of needles 41 on the outermost side is minimum.

At this time, if the first stage group consists of a number of needles 41, the Nth stage group is formed to consist of a*N number of needles 41. 6 shows an example consisting of a total of three groups. An example in which the first stage group is composed of two needles and the third stage group is composed of six needles. At this time, for the efficiency of fluid introduction, the needles 41 of the first stage group among the needles 41 disposed on the needle plate main body surface 45 are formed so that the fluid through-holes 411 are not provided. In addition, it is preferable that the first and last needles 41 of the needles 41 of the third stage group are also configured not to have fluid passage holes 411 .

Second embodiment of needle plate

Hereinafter, a second embodiment of the needle plate 40 applied to the skin stimulator of the present invention will be described with reference to FIGS. 7 to 14.

7 is an enlarged view of a needle plate of a second embodiment of the skin stimulator according to the present invention, and FIG. 8 is an enlarged schematic view of the needle body of FIG. 7 .

The needle plate 40 of the present invention has a structure in which fluid is supplied to the inside of the skin through a needle flow passage 413 built into the needle 41 while the needle 41 is inserted into the skin. The fluid receptor 10 is tilted or pressurized so that the fluid (meaning 'cosmetic solution') is discharged to the fluid discharge hole 11, and the fluid discharged from the fluid discharge hole 11 forms a flow path in the vertical direction. It flows into the fluid flow path 21.

The fluid that has flowed to the upper end of the fluid flow path 21 flows up to the fluid discharge hole 31 of the flow path plate 30, and the fluid discharge hole 31 and/or the fluid flow groove 32 has each needle 41 ) communicates with the needle passage part 413 built in. Each of the needles 41 includes a needle passage portion 413, and the fluid is configured to be discharged from the needle 41 through the needle passage portion 413.

Specifically, the needle 41 includes a needle body 412, a needle passage portion 413, and a fluid through hole 411.

Referring to FIG. 7 , the fluid through hole 411 is located at the front end of the needle body 412 . The fluid through hole 411 means a hole (or opening) through which fluid is discharged. When the fluid passage hole 411 is located at the front end of the needle body 412, there is an advantage in that the fluid can be injected into the deepest position while the needle 41 is inserted into the skin.

The needle body 412 is formed into a shape for insertion into the skin. That is, it is preferable to be formed in a cone shape in which the horizontal cross-sectional area decreases toward the top. The upper end of the needle 41 is a part that penetrates the skin. This is because when the upper end of the needle 41 is not sharp, the needle body 412 is not retracted and a bending phenomenon may occur. Accordingly, the fluid stored in the skin stimulator of the present invention can be composed of a cosmetic solution that exhibits a greater effect when inserted inside the skin rather than applied to the outside of the skin. As described above, the lower end 414 of the needle body 412 may be configured to have the largest cross-sectional area (meaning a horizontal cross-sectional area).

As shown in FIG. 12 , the shape of the cross section of the needle body 412 may be selected as an appropriate shape according to the designer's choice. All are formed in a horn shape, but as shown in FIG. 12 (a), the horizontal cross section may be composed of a quadrangle, and as shown in FIG. 12 (b), the horizontal section may be composed of a triangle. These only show examples of horizontal cross-sections, and specify in advance that they may be configured in a variety of shapes as well as n-gons.

The needle passage part 413 is located inside the needle body 412 . That is, the inner circumferential surface (or inner surface) of the needle body 412 having a predetermined thickness forms an empty space, and the empty space forms the needle passage portion 413 . The shape of the needle passage part 413 may correspond to the shape of the needle body 412 . When the needle body 412 has a conical shape, it means that the needle passage part 413 may also have a conical shape.

The needle passage part 413 may be formed such that its horizontal cross-sectional area decreases toward the top. Examples include shapes such as a cone, a quadrangular pyramid, and a polygonal pyramid. As the needle passage portion 413 narrows toward the front end, the cosmetic solution can be smoothly injected into the skin even when the needle 41 is drawn into the skin. That is, by maximizing the discharge pressure of the cosmetic solution, it is possible to smoothly inject into the skin. This is because when the needle 41 is drawn into the skin, it may receive resistance pressure from materials inside the skin. By exceeding this resistance pressure, the cosmetic solution can be supplied into the skin.

9 to 11 show modified examples in which the fluid through-holes of the needle body are formed at various positions. 9 and 10 show a structure in which fluid through-

holes

1411 and 2411 are formed on the outer circumferential surface of the needle body, and FIG. 11 shows a structure in which the fluid through-hole 3411 is positioned slightly below the tip of the needle body.

The modified example of the needle 141 shown in FIG. 9 shows a structure in which the fluid through hole 1411 is located only on the outer circumferential surface of the needle body 1412. In the modified example, the distal end forms a cusp, which is the most advantageous structure for the needle 141 to be drawn into the skin.

The modified example of the needle 241 shown in FIG. 10 shows a structure in which fluid through-

holes

2411 and 2415 are formed on the outer circumferential surface and the front end of the needle body 2412, respectively. The modified example includes a fluid through hole 2415 at the front end, so that the cosmetic solution can be supplied to a position deep in the skin. In addition, fluid through-holes 2411 are formed at predetermined intervals on the outer circumferential surface of the needle body 2412, so that the cosmetic solution can be supplied to all positions from the top to the bottom where the needle 241 is inserted into the skin. For example, when the height of the needle body 2412 is 0.01 mm, the cosmetic solution can be supplied to any height from 0 to 0.01 mm based on the vertical cross section of the skin.

The modified example of the needle 341 shown in FIG. 11 shows a structure in which the front end of the needle body 3412 forms an apex, but a fluid through hole 3411 is formed below the apex adjacent to the apex. Based on the vertical cross section, the needle body may be divided into a first side 3412 and a second side 3415. Although the slopes of the first and second sides 3412 are currently shown in FIG. 11 as being the same, the slopes may be formed differently.

For example, the second side slant 2 may be larger than the first side slant 1 . 11, the fluid passage hole 3411 has a structure biased to the outer circumferential surface 3412 on the second side, so that the second side slope 2 is set to the first side slope in order to adjust the direction in which the cosmetic solution is discharged. It is to make it larger than (1). This is because a larger inclination provides less friction or resistance when the fluid flows along the inner circumferential surface. That is, it is preferable to form a larger slope on the side where the fluid through hole 3411 is deflected.

12 shows a modified example in which a needle body is formed in various shapes. 12 (a) to (c) show a structure in which the fluid through-

holes

411a, 411b, and 411c are located at the front ends.

12 (a) shows a needle 41a in the form of a quadrangular pyramid with a square horizontal cross section, (b) shows a needle 41b in the shape of a triangular pyramid with a triangular horizontal cross section, and (c) shows a needle 41b in the shape of a cone. The needle 41c is a type in which the needle 41c is equipped with a needle body in order to better enter the skin. The drawing-in blades extend in the same direction as the drawing-in direction, and a plurality of drawing-in wings may be provided along the outer circumferential surface of the needle body.

13 shows a modified example of the needle passage part.

13 (a) shows a cylindrical needle passage part 4413, and (b) shows a tree-shaped needle passage part 5413.

The cylindrical needle passage part 4413 means a structure in which the inner circumferential surface of the needle body 4412 is formed in a cylindrical shape. That is, as a structure formed in a straight line, it can be applied when a small amount or one-time injection of fluid into the skin.

The tree-shaped needle passage part 5413 may be divided into a plurality of regions from an upper end to a lower end. 13(b) shows a structure divided into first to

fourth zones

5413a, 5413b, 5413c, and 5413d. Inclinations of the first to

fourth regions

5413a, 5413b, 5413c, and 5413d may be formed differently. The slope of the first region 5413a is the gentlest, and the slope of the fourth region 5413d is the largest. This is because it is the most adjacent part to the skin in the state of being drawn into the skin, by forming the largest slope, to minimize the frictional force and the resistance force.

Description of cap module

Referring to FIG. 14, the cap module 50 applicable to the skin stimulator of the present invention will be described. The cap module 50 is composed of a push unit 51 and a cap frame 56. The cap frame 56 is configured in a hollow shape, and the push unit 51 is configured to move in the vertical direction. The inside of the cap frame 56 is provided with a disinfection solution storage unit 53 in which a disinfectant solution (eg, alcohol) is stored.

Referring to (b) of FIG. 14, a discharge hole is formed on the lower side of the disinfection solution storage unit 53, and when the disinfection solution storage unit 53 moves downward by pressing through the push unit 51, the supply The disinfectant solution is configured to flow to the lower side of the cap frame 56 through the hole.

A suction hole is formed on the lower side of the cap frame 56, and is configured to match the discharge hole to receive the disinfectant solution only when the disinfectant solution storage unit 53 moves downward. In normal times, the disinfection solution storage part 53 rises again by the vertical elastic part 54, and the discharge hole and the suction hole do not coincide with each other, so that the flow of the disinfection solution is blocked.

Since the skin stimulator according to the present invention is provided with a needle plate 40 that is inserted into the skin, disinfection is required due to its nature. Although there is a method of separately spraying the disinfectant solution, it is most efficient to use the disinfectant solution stored in the cap module 50 as it is very cumbersome from the user's point of view.

A plurality of disinfectant spray holes 55 are provided on the bottom surface of the cap module 50. When the push unit 51 is pressurized, the disinfectant solution is sprayed onto the needle plate 40 through the disinfectant spray holes 55. can be sprayed. This process is preferably performed in a state where the cap module 50 covers the fluid container 10, that is, in a state where the cap module 50 is inserted.

In the process of removing the cap module 50 after spraying the disinfectant solution, the sprayed disinfectant solution may evaporate into the air.

Meanwhile, the needle plate 40 applied to the present invention may be used once. This is because there is a risk of infection and the needle 41 may be contaminated when used by a large number of users. Accordingly, it is preferable that the needle plate 40 is used once. For the convenience of one-time use, handles 44a and 44b may be provided on one side of the needle plate 40 . The

handles

44a and 44b are formed in an 'L' shape and can be easily removed from the plate groove 33. In addition, when the new needle plate 40 is seated in the plate groove 33, the needle plate 40 can be stably inserted into the plate groove 33 through the

handles

44a and 44b.

Third embodiment of needle plate

Hereinafter, a third embodiment of the needle plate applied to the skin stimulator of the present invention will be described with reference to FIGS. 15 to 19. For convenience of description, overlapping descriptions with those of the first and second embodiments will be omitted, and description will focus on differences.

The needle plate 640 of the third embodiment is distinguished from the needle plates of the first and second embodiments 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. 16 , 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 third 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, the structure in which the cone-shaped needle body 6412 is applied in FIG. 16, but a needle body of a different shape, such as a polygonal pyramid or a whirlwind cone, can be applied.

Referring to FIG. 19 , various forms of the peripheral passage part 643 will be described.

19 (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. 19 will be described. All of these are structures in which unit shapes repeat and surround the needle body 6412. 19(b) is a structure in which triangles are combined, and has a star shape as a whole. 19(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. 18 and 19 , a vertical section of the peripheral flow path portion 643 will be described in detail. The peripheral passage part 643 may be configured in a straight vertical section (refer to FIG. 16(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. 19, 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 .

The above embodiment in the present invention 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 effect is included in the technical scope of the present invention.
