Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skin applicator having a valve mechanism for applying a liquid or powder coating agent such as a drug or cosmetic.

[0002]

2. Description of the Related Art Conventionally, as an applicator for applying an application agent for skin, an applicator having a tip end of an applicator main body and an application destination fixed thereto is known. As the applicator body, there are known a shaft cylinder having only a function as a gripping portion, a shaft cylinder having a coating agent accommodating portion formed therein, and the like. As an application destination, a brush and the like used for an eyeliner and the like of makeup tools are known. Each brush has multiple independent brushes that are bundled together, and the bases of the brushes are put together by gluing or welding, tied with a thread, and the cross section is round. A brush and a flat brush with a flat shape are known. Since the round brush-shaped brush ears have a substantially conical shape, the visibility of the tip of the brush is good, and the cosmetic agent can be accurately applied to the intended place.

In addition to the brush-brush type applicator described above, a flexible and deformable application destination is attached in front of the opening of the container body having the application agent accommodation chamber, and between the application agent accommodation chamber and the application destination. There is an applicator in which a valve mechanism is arranged. As this applicator, Japanese Utility Model Publication No. 42-13671 discloses a valve hole 2 having a collar 1a formed on the upper side and a hole formed in the center so that a valve rod 3 integral with a conical valve seat 3a is projected to a lower inner edge 1b. The upper end of the locked spiral ridge 4 is fixed to the lower surface of the valve seat 3a 3a ', and the inner lid 1 with the valve seat pressed against the valve hole 2 is inserted into the mouth of the container body 8 and The outer lid 5 having the thick sponge rubber body 7 adhered to the receiving plate 5a from the upper part is capped so that the valve rod 3 penetrates the valve hole 6 at the center of the receiving plate and is inserted into the sponge rubber body. A device having a coating liquid container formed by capping the cap 10 is disclosed. When the skin is touched by insects such as mosquitoes and the drug solution is applied to the affected area with the above-mentioned liquid container for application, the sponge rubber body, which is the application destination, is soft and elastic, so the drug solution is applied to the affected area affected by the insect. It can be applied uniformly.

[0004]

With an applicator using a brush tip, when the drug solution is applied to the affected area by the skin being caught by insects such as mosquitoes, it is good to apply it accurately to the affected area. Since the brush is soft, there is a problem that it takes time to neutralize the venom of insects until the applied drug solution penetrates deep into the affected area, and it is difficult to immediately reduce the itch. Also, when applying a hair-growth agent to the scalp with an applicator that uses a brush tip, the brush tip may be deformed and damaged by hair, etc., or it may be blocked by the hair and the hair-growth agent may not be sufficiently supplied to the hair root, or the brush tip is soft. As the brush tip spreads and deforms and the side surface of the brush tip contacts the scalp, there is a problem that it is difficult to exert a massage effect by stimulating the scalp. Furthermore, since the brush brush requires multiple brushes and it is necessary to put them together, it takes a lot of work, and the detailed shape (length, thickness,
There is a problem that there are variations in the tapered shape, etc.). On the other hand, with an applicator using a sponge rubber body, in order to neutralize the venom of insects, it takes time until the applied drug solution penetrates deep into the affected area, and it is difficult to immediately reduce the itch. there were. When applying a hair-growth agent to the scalp with an applicator that uses a sponge rubber body, as with the brush, it is difficult to supply the hair-growth agent to the hair roots due to the hair being blocked or it is soft, so stimulating the scalp There was a problem that it was difficult to express the massage effect of. Further, the sponge rubber body, which is the application destination of the application liquid container described above, has a substantially columnar shape, but since the circular surface of the tip is flat and wide, even when trying to apply mainly to the affected part that was caught by an insect, the tip The chemical solution had to be applied so that the circular surface of was directed to the position considered to be the affected area. That is, unlike the above-described applicator using a brush, there is a problem in that it is difficult to apply the chemical solution accurately, centering on the place where the insect bites. The present invention shortens the time until the applied drug solution penetrates into the back of the affected area, and accelerates drug efficacy such as reducing itchiness quickly. In addition, it should be possible to supply a sufficient amount of hair restorer to the scalp even if there is hair, so that the massage effect can be exhibited by stimulating the scalp. Further, like an applicator using a brush, it enables accurate application of the drug solution to an affected part such as a place where a bug is caught, and there is little manufacturing variation like an applicator using a sponge rubber body. An object is to provide an applicator for skin. From the above problems, the present inventor has completed the present invention by paying attention to the hardness of the application piece such as the application destination member and studying an appropriate flexural load range.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a large number of flexibly deformable coating pieces are continuously provided at a base portion in front of an opening of a container having a storage portion for coating agent therein, and a valve mechanism is provided at a rear portion thereof. A coating tip provided with a valve seat portion for receiving a valve, a leading tip piece that can be flexurally deformed rearward from the center of the tip of a large number of coating pieces, and a valve portion that abuts the valve seat portion of the valve mechanism are connected in series. In the applicator with a valve in which a valve member biased from is arranged, the deflection load of each application piece of the application destination is 0.0 per 1 mm displacement.
The gist of the present invention is to provide a skin applicator characterized in that the deflection load of the tip piece of the valve member is set to be larger than the deflection load of the application piece to be 02N to 0.020N.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail below with reference to the accompanying drawings. First Embodiment FIGS. 1 to 5 show a first embodiment. 1 is a sectional view of a main part, FIG. 2 is a side view of FIG. 1, FIG. 3 is a top view of FIG. 2 excluding a cap, and FIG. 4 is an explanatory view of a coating state of the first embodiment. Yes, FIG. 5 is an explanatory diagram of a coating state in which the coating tip is excessively pressed in the first embodiment. Reference numeral 1 in FIG. 1 is a container. The container 1 is provided with a storage portion for storing the coating agent in the rear, an opening at the front end in the front, and a male screw portion around the opening. In front of the container body 1, a front shaft 2 having a substantially tubular shape as a whole and penetrating therethrough is attached by screwing. The front shaft 2 has a single-cylindrical member on the front side and a double-cylindrical member on the rear side. A female screw portion is provided on the inner surface of the outer cylinder between the rear double cylinders so as to be screwed with the male screw portion of the previous container.

The front shaft 2 is provided with a coating destination 3 which projects from the inside to the front and which is flat in the front and cylindrical in the rear and communicates with the front and back. The application destination 3 includes a coating portion 3b in which a large number of coating pieces 3a that can be flexibly deformed and have a substantially semicircular cross section are formed, an outer cylinder portion 3c that follows the coating portion 3b, and an outer cylinder portion 3
It is formed by the inner cylindrical portion 3d provided inside the front of c. The coating portion 3b has a substantially semicircular cross section having a circular outer side and a flat inner side, and has a plurality of coating pieces 3a that are tapered from the rear side to the front side in a row in the lateral direction. It is formed by superimposing a large number and aligning the outer row and the inner row at the tips, and is a flat, flat brush-like shape as a whole. The tip of each application piece 3a is provided to have a hemispherical and pointed shape. The shape of the application piece 3a
The taper from the back to the front means that when the application tip is molded by the injection molding method, the thin application piece that is resin-filled in the mold may be stretched, twisted, cut or damaged. This is so that it can be easily taken out from the mold (= improving the mold releasability) without being provided. Further, by tapering the application pieces, the gap between the application pieces becomes wider in the front and narrower in the back, so that the coating agent can be easily guided to the front of the application destination, and the outer side at the rear of the application destination can be achieved. It is also made possible to suppress the exudation of the coating agent. In the applicator for skin of the present invention, the deflection load of each application piece at the application destination is 1
It is necessary to make 0.002N to 0.020N per mm displacement. This is because when the deflection load is less than 0.002N, the skin of the skin is struck by insects such as mosquitoes, and when the drug solution is applied to the affected area, the application point becomes too soft like a brush, so the skin surface is not affected. The expansion and contraction effect is weak, and the applied drug solution is used to neutralize the venom of insects until the applied drug solution penetrates deep into the affected area.
It takes time and it is difficult to immediately reduce itchiness. If it exceeds 0.020N, if the application tip is accidentally pressed against the skin excessively, the application tip will become too hard. This is because there is a problem that it becomes excessive and the skin is damaged. By the way,
The bending load of the coating piece 3a can be set from design elements such as length, thickness, width, and elastic coefficient of the material used by using a cantilever beam load calculation formula. On the front inner surface of the coating row on the center side of the coating portion 3b, two locking portions 3e each having a substantially right-angled triangle shape with rounded vertices when viewed from the upper surface protruding inward are provided so as to be arranged in point symmetry at the center. ing. Through holes are formed inside the coating destination 3. The coating piece 3 is placed in this through hole.
a An opening having a square cross section is provided from the rear end toward the rear, a cylindrical inner cylinder 3d is provided behind the opening, and a valve seat of the valve mechanism is provided at an intermediate position in the front and rear of the inner surface of the inner cylinder 3d. Part 3f
Is provided. A projecting peripheral rib is provided on the outer peripheral rear end of the outer cylindrical portion 3c of the application destination 3 to connect the front shaft 3 and the rib over the rib.

Inside the coating destination 3, the coating piece 3a of the coating destination 3 is provided.
The valve member 4 having a valve function and a spring function is attached from the center of the front end to the rear end through the opening. The front end of the valve member 4 is provided with a deflectable tip piece 4a. The tip piece 4a is provided so that the front end is located immediately behind the locking portion 3e of the coating destination 3, and the rear side thereof is the coating destination 3
It is provided so as to pass through the opening. Here, the tip piece 4a
It is necessary to make the bending load of the coating material larger than that of the coating piece 3a. This is because when the flexural load of the tip piece 4a is smaller than the flexural load of the coating piece 3a, the valve opening in the valve mechanism becomes insufficient and the problem of insufficient discharge of the coating agent occurs. For this reason, the tip piece 4a has a rectangular plate-like cross section, its thickness and width are made larger than those of the application piece 3a of the application destination 3, and its length is made a little longer, so that the valve opening in the valve mechanism is increased. Is sufficient so that the coating agent can be appropriately discharged. Therefore, the deflection load of the tip piece 4a becomes large with the deflection load of the application piece 3a of the application destination 3 and the tip piece 4a of the valve member 4 using the same material. The bending load of the tip piece 4a can be calculated by using the cantilever beam load calculation formula to calculate the length, thickness,
It can be set from design factors such as width and elastic modulus of the material used. A valve portion 4b having a hemispherical shape on the front side is provided at the rear end of the front piece 4a. A tubular front tubular portion 4c is provided behind the valve portion 4b. Two spring portions 4d each having a substantially semicircular vertical cross section and a spiral shape as a whole are continuously provided behind the front cylindrical portion 4c.
A cylindrical rear cylinder portion 4e is provided rearward from the rear end of the spring portion 4d. The rear cylinder portion 4e is provided so as to be fitted to the inner surface of the outer cylinder portion 3c of the application destination 3 at the rear side. The valve member 4 is fixed to the outer cylinder portion 3c of the application destination 3 by the rear rear cylinder portion 4e, and the valve portion 4b biased forward by the spring portion 4d is connected to the valve seat portion 3f of the application destination 3 and the circumferential line. The valve mechanism is formed by closely contacting and pressing.

Deflection load of application destination: 0.0383N Deflection load of valve member: 0.3450N

Regarding the effects of the first and second examples, the first comparative example and the second comparative example together with FIG. 4, which is an explanatory view of the state of application to the skin of the arm, are excessively applied to the same part. The description will be made with reference to FIG. 5, which is an explanatory view of the application state where the tip is pressed. Reference numeral 6 is the skin of the arm. When the application piece of the application destination is pressed against the skin at the time of application, as shown in FIG. 4, the skin at the pressed portion is dented and the application piece is bent and deformable, so that the application piece is bent and deformed. At the same time, the tip piece of the valve member that is projected between the rows of application pieces can also be bent and deformed, so that it is bent and deformed. At this time, the front end of the front end of the valve member is locked and abutted on the rear surface of the front end of the application piece pressed against the skin, and the front end of the front piece is prevented from slipping forward. Therefore, the force of the tip deflection to return to the original shape acts against the spring portion behind the valve portion, the valve portion of the valve member separates from the valve seat portion of the application destination, opens the valve, and The coating agent is supplied to the coating piece to be coated. Regarding the degree of deflection of the application piece and the tip piece, the application piece is made larger than the tip piece, so that the chord length of the curve is smaller in the application piece than in the tip piece. Then, the dimensional difference in the chord length becomes the moving distance to the rear of the valve portion, that is, the valve opening length. Therefore, the valve opening length increases as the difference in the degree of deflection increases. Thus, in the skin applicator according to the present invention, at the time of application, the application piece of the application destination and the tip piece of the valve member are flexibly deformed, but at the same time, the tip end of the valve member is attached to the rear surface of the engaging portion of the application piece. Locks and abuts to open the valve, so the opening length of the valve can be efficiently increased, or the opening operation of the valve responds immediately, so an appropriate discharge amount can be secured even if the viscosity of the coating liquid of the coating agent increases. However, the time required for the coating liquid to pass through the valve opening portion can be shortened.

Further, observing a state in which the application portion of the application destination is pressed against the skin of the arm, the tip of each application piece is not pressed against the skin in a gathered state, but each application piece individually. It is pushed away. That is, the skin is raised between the tips of the application pieces. In this way, since the skin is pressed against a large number of dots, which is the total number of applied pieces, on the skin surface, a part that is pressed and compressed, and a part that is stretched due to a ridge that is between the pressed parts. Occurs, and at the same time, the coating agent from the container is supplied to the skin surface. When the application part is moved on the skin, the compression part and the extension part of the skin are reversed. For hairy skin such as the scalp,
The application piece of the application destination enters between the hairs, that is, the hair is interposed between the application pieces, the tip of the application piece is pressed against the scalp surface, and the application agent is directly supplied to the scalp. Here, when the drug solution was applied to the affected area held by the insect by pressing it at an angle of 70 degrees, which is a general condition of use, and the reduction in itching sensation due to pain on the skin was evaluated. Although the effect can be recognized in the first example, the second example, and the second comparative example, in the first comparative example, the application destination largely bends as shown in FIG. 5, no pain sensation occurs, and the effect of reducing itchiness is reduced. unacceptable. On the other hand, when the state of being pressed against the skin covering the hard bones of the skull, such as the scalp, is observed, a large number of points are pressed with the tip of each application piece being individually separated. A coating agent as a hair promoting agent was applied by pressing the coating tip in a general use state at an angle of 70 degrees, and the pressing feeling of the coating tip on the scalp was evaluated. In the second example and the second comparative example, a feeling of massage is recognized, but in the first comparative example, the application tip is largely bent, and the feeling of massage is not recognized. Next, looking at the situation where the coating destination is excessively pressed, in the first embodiment and the second embodiment, the coating destination bends largely as shown in FIG. 5, the side surface of the coating destination is pressed, and Since the tip does not dig into the skin, no local pain sensation occurs, but in the second comparative example, the application tip is hard and the pain sensation becomes excessive before it is largely bent as shown in FIG. Therefore, in the case of an insect bite, in the compressed part of the skin, a slight pain sensation occurs to relieve the itchiness, and in the stretched part of the skin, the absorption of the drug solution is promoted by the expansion of cells and hair roots. In other words, it is possible to alleviate the itching sensation and accelerate the absorption of the drug solution to the affected area at the same time, and it is possible to accelerate the drug efficacy. The scalp can bring a feeling of massage. Even if the application target is accidentally pressed excessively, the application target is largely deflected and the side surface of the application target is pressed, so that the skin is not damaged. Even with a hairy skin such as a scalp, it is not hindered by hair, and the application agent can be supplied at the same time when the tip of the application piece to be applied is directly pressed against the skin surface. Even when the coating agent is being supplied,
Unlike the applicator using a sponge rubber body, the application agent stored in the sponge rubber body is not applied, but a hygienic application agent is supplied from the container to the skin surface at the same time as the valve is opened at the time of application. So it is more hygienic. Also, the visibility of the application destination is good, as with an applicator using a brush tip, and
It is possible to provide an application destination with less manufacturing variation, such as an applicator using a sponge rubber body. Separately, if a member such as an application destination is molded using a thermoplastic resin material in which an antibacterial agent is kneaded, propagation of various bacteria adhering from the skin or the atmosphere can be reduced. The applicator can also be used as a massage cosmetic agent for the skin of the face, a depilatory agent, and the like.

The effects of the third and fourth embodiments will be described together with the third comparative example. The third embodiment, the operational effect of the fourth embodiment is substantially the same as the first embodiment, when the application piece of the application destination is pressed against the skin at the time of application, the skin of the pressed portion is depressed and the application piece is flexible. Since it is deformable, it can be bent and deformed. At the same time, the tip piece of the valve member provided at the center of the application portion is also bendable and deformable, so that it is also curved and deformed.
At this time, the front end of the front end of the valve member is locked and abutted on the rear surface of the front end of the application piece pressed against the skin, and the front end of the front piece is prevented from slipping forward. Therefore, the force of the tip deflection to return to the original shape acts against the spring portion behind the valve portion, the valve portion of the valve member separates from the valve seat portion of the application destination, and the valve opens,
The coating agent in the container is supplied to the coating piece to be coated. Also regarding the degree of deflection of the coating piece and the tip piece, the same as in the first embodiment, the greater the difference in the degree of deflection of the coating piece and the tip piece,
The valve opening length also becomes longer. In this way, the skin applicators according to the third and fourth examples can be applied in the same manner as in the first example. Furthermore, since the inner cylinder part of the application destination and the front cylinder part of the valve member are both long in the front and back, the gap between them is also long in the front and back, and even a low-viscosity liquid coating agent can be used depending on the liquid viscosity. An appropriate discharge amount can be secured by setting a different gap value. The tip of the brush is round, so no matter which direction you apply it,
It can be applied with a uniform width.

Further, in the state in which the application portion of the application destination is pressed against the skin, the tip of each application piece is pressed apart from each other as in the first embodiment, so that the tip of the application piece is pressed. Causes skin bumps. The skin is pressed against a large number of dots, which is the total number of applied pieces, and a part where the skin is pressed and compressed and a part where a ridge that is a space between the presses is stretched is generated on the skin surface. The state of application to the scalp and the like is the same as in the first embodiment. At the affected part of the insect bite, the itch feeling is alleviated and the drug solution is absorbed at the same time. Here, the medicinal solution was applied to the affected part held by the worm by pressing it with the application tip being in a general use state obliquely (for example, 70 degrees), and evaluated for reduction of itching sensation due to pain sensation on the skin. However, the effect is recognized in the third example, the fourth example, and the third comparative example. Next, looking at the situation where the application tip is excessively pressed, in the third and fourth examples, the application tip bends greatly, the side surface of the application tip is pressed, and the tip of the application piece bites into the skin. Since there is no local pain sensation, in the third comparative example, the application tip is hard and the pain sensation is excessive and it cannot be used. The effect on the affected area and scalp, etc.
Other characteristics are similar to those of the first embodiment.

[0021]

EFFECT OF THE INVENTION The skin applicator of the present invention shortens the time taken for the drug solution, which is an application agent, to penetrate into the deep part of the affected area, speeding up the medicinal effect such as reducing itchiness. Further, even if hair is present, a hair-growth agent, which is an application agent, can be sufficiently supplied to the scalp, and a massage effect by stimulating the scalp can be exhibited. Further, like an applicator using a brush, it enables accurate application of a drug solution to an affected area such as a place where a bug is caught, and there is little manufacturing variation like an applicator using a sponge rubber body. It has the advantage of being able to provide a skin applicator.
