That is, as shown in FIG. 1 and FIG. 2, when the support portion 20 is provided, the rib 40 is provided at the same position as the start point of the support portion 20. Thus, by using the support portion 20 and the rib 40 in combination, it is possible to maintain the shape of the gastrocnemius muscle and to further prevent the loss of the pumping effect by the muscle. The rib 40 does not necessarily have to be used in combination with the support portion 20, and the rib 40 can be provided with the function of holding the gastrocnemius with only the rib 40 without providing the support portion 20.

〔how to use〕
In order to wear the covering tool 1 formed in this way, first, a toe is inserted from the upper opening 10A. Then, the region close to the ankle is taken out from the lower opening 10B, and the upper opening 10A is pulled upward so that the support portion 20 is located in the vicinity of the gastrocnemius muscle of the calf, and the wearing is completed. At this time, since the entire covering tool 1 is formed to have a diameter smaller than that of the calf, it is necessary to put a finger from the upper opening 10A and pull it upward while spreading the covering tool 1. Since the waterproof part 30A which consists of a convex ridge of a book is formed, the upper opening 10A can be smoothly pulled up by putting a finger on these convex ridges.

During wearing, since the diameter is smaller than a part of the human body to be worn and the openings are provided at both ends, a high moisturizing effect can be obtained without losing the moisture of the skin. In addition, pressure is applied to the gastrocnemius muscle constituting the calf in order to closely press the calf in a state where the fabric forming the covering tool 1 is stretched. As a result, it is possible to obtain the effect of preventing lymph from staying in the vicinity of the calf, and it is possible to prevent edema. In addition, since the covering device 1 is provided with the support portion 20 for fixing the gastrocnemius and holding the muscle, the pumping effect by the muscle can be maintained without breaking the shape of the gastrocnemius, and further prevention of edema You can get the effect of Furthermore, since a rib 40 is formed at a position corresponding to the lower end of the gastrocnemius muscle inside the covering tool 1, the shape of the gastrocnemius muscle is maintained together with the effect by the support portion 20, and the pump effect by the muscle is further enhanced. It can be further improved.

Moreover, although you may wear the covering tool 1 on bare skin, the effect can be improved by applying the oil which has a tightening effect and a massage effect on a skin, and wearing the covering tool 1 on it. That is, in addition to the pressurization effect and the gastrocnemius muscle support effect of the covering tool 1, the further edema prevention effect can be obtained by adding the effect by oil. Also, by applying oil, the friction between the skin and the fabric is eliminated, and smooth wear becomes possible. As oil to be applied to the skin, in addition to those having a tightening effect and a massage effect, so-called aroma oils with a scent can be applied.

Moreover, the effect of edema prevention can be expected by bathing in the state which wore the covering tool 1 in this embodiment. That is, since the covering tool 1 in the embodiment is made of an elastomer such as thin silicone rubber, the thermal conductivity is high, and if bathing while being worn, a higher warm bath effect can be obtained. As a result, the blood flow and the flow of lymph are promoted and the further effect of pushing up the lymph which tends to stay in the lower body is obtained, and the synergistic effect of the pressure effect and the warm bath effect by the covering device 1 itself further prevents edema You can get the effect.

In addition, since the covering tool 1 in the embodiment is made of a stretchable elastomer, the covering tool 1 is provided with a predetermined thickness before being attached to the human body, and the covering tool 1 after being attached to the human body. Can be made as thin as possible. If the covering tool 1 is too thin, it will affect the mounting ease of the covering tool 1, but by providing the covering tool 1 with a stretchable property, by applying a predetermined thickness to the covering tool 1 before wearing on the human body, Ease of installation can be ensured.

On the other hand, the covering tool 1 can be made as thin as possible after wearing on the human body. As the thickness of the covering tool 1 is thinner, heat loss due to the elastomer can be suppressed, and when bathing while wearing the covering tool 1, the heat possessed by the warm water in the bath can be transmitted to the wearer as it is. Is obtained. As a result, the blood flow and the flow of lymph are promoted and the further effect of pushing up the lymph which tends to stay in the lower body is obtained, and the synergistic effect of the pressure effect and the warm bath effect by the covering device 1 itself further prevents edema It is possible to obtain an effect, a skin care effect, a moisturizing effect, a sweating effect, a fatigue recovery effect, a slimming effect, and a dirt removing effect on pores.

And since waterproofing

parts

30A and 30B are provided in upper opening 10A and lower opening 10B in covering tool 1 in this embodiment, it is possible that hot water stretched in a bath infiltrates between covering tool 1 and the skin. It can be prevented. That is, three convex streaks are formed in each of the

waterproof portions

30A and 30B, and these convex streaks bite into and adhere to the skin to prevent the entry of water.

At this time, since the ridges have a substantially rectangular cross-sectional shape, it is possible to secure a wide area where the ridges and the skin are in close contact, and it is possible to reliably prevent the entry of water.

In addition, since the height of the ridges in the radial direction is set so that the outermost ridges are higher than the two ridges on the inner side, infiltration of water at the end of the covering tool 1 can be reliably achieved. It has a function to prevent. In addition, since the height of the ridges at the outermost side is the highest, the covering tool 1 can be pulled up without distortion when worn. That is, since the covering tool 1 in the present embodiment is stretchable as a whole and has a diameter smaller than that of the calf, if the heights of the three ridges are equal, the finger is inserted from the upper opening 10A. When the covering tool 1 is spread and pulled upward, there is a possibility that the finger may not be well scratched, and the shape after wearing may be distorted. In such a case, the

waterproof portions

30A and 30B do not function, and water infiltrates. In this embodiment, since the height in the radial direction of the outermost ridge is set higher than the two inner ridges, it is possible to easily put a finger on the outermost ridge. ing. Therefore, the coating tool 1 can be pulled up without causing distortion, and the effects of the

waterproof portions

30A and 30B can be sufficiently exhibited.

Due to the function of the

waterproof portions

30A, 30B, the covering device 1 in this embodiment is used not only for the purpose of edema prevention but also as a waterproof cover for preventing wounds and the like from getting wet during bathing. Can. In this case, even if water intrudes from the upper opening 10A and / or the lower opening 10B, the covering tool 1 is formed to have a small diameter so that the entire covering device 1 adheres to the calf, preventing the water from reaching the affected area. Can. Therefore, it becomes possible to take a bath with ease by attaching the covering tool 1 in the present embodiment to the affected part.

As mentioned above, although one form for implementing this invention was demonstrated, below, another embodiment is described.

FIG. 3 shows the structure of the waterproof portion 30A of various types. A desired function can be obtained by the radial height and shape of the ridges. The waterproof portion 30B in the lower opening 10B has the same structure as the waterproof portion 30A in the upper opening 10A except that the upper and lower portions are reversed.

The waterproof part 30A shown in FIG. 3A has the same structure as that shown in FIG. That is, the waterproof portion 30A is composed of three

convex streaks

31A, 32A, 33A having a substantially rectangular cross section provided in the circumferential direction on the inner peripheral surface of the upper opening 10A. The height of the ridges in the radial direction is highest at the outermost ridge 31A, and the height of the two

inner ridges

32A and 33A is set lower than the height of the outermost ridge 31A. It is done. In this case, although the heights of the two

inner ridges

32A and 33A are set to be the same, the outermost ridge 31A is the highest, and the inner ridge 33A is the lowest. The convex ridge 32A in the middle may have an intermediate height.

In this case, as described above, since the outermost ridge 31A is set higher than the two

ridges

32A and 33A on the inner side, entry of water is reliably prevented at the end of the covering tool 1 Have a function to Moreover, since it is a structure which is easy to put a finger on convex ridge 31A in the outermost side, covering tool 1 can be pulled up without distortion at the time of wearing.

Waterproof part 30A shown in FIG.3 (b) shows the modification of waterproof part 30A shown to Fig.3 (a). That is, the heights of the outermost ridge 31A and the middle ridge 32A are the same as those of the waterproof portion 30A shown in FIG. 3A, but the height of the inner ridge 33A is the largest. The height is set to be the same as the height of the outer ridges 31A.

In this case, since the height of the innermost ridge 33A is set to be as high as the height of the outermost ridge 31A, it is easy to put a finger on the innermost ridge 33A, which is more reliable. The covering tool 1 can be pulled up to be worn without distortion. Further, even if water infiltrates through the

ridges

31A and 32A, the ridge 33A can reliably prevent the water from entering.

Waterproof part 30A shown in FIG.3 (c) shows the modification of waterproof part 30A shown in FIG.3 (b) further. That is, the ridges 34A are further provided inside the ridges 33A, and the height of the ridges 34A is set lower than the

ridges

31A and 33A, similarly to the height of the ridges 32A.

In this case, the effect of preventing the entry of water can be improved by the action of the four ridges. In addition, since the height of the innermost ridge 34A is set low, water penetration is prevented while maintaining a comfortable wearing ability that can withstand long-time wearing without giving an excessive sense of pressure to the calves. The effect can be improved.

Waterproof part 30A shown in FIG.3 (d) shows the modification of waterproof part 30A further shown in FIG.3 (c). That is, the height of the innermost ridge 34A is set high similarly to the outermost ridge 31A, and the height of the ridge 33A is the same as the height of the ridge 32A in the ridge 31A. It is set lower than the height.

In this case, the effect of preventing the entry of water can be improved by the action of the four ridges. In addition, since the height of the innermost ridge 34A is set to be the same as the height of the outermost ridge 31A, it is easy to put a finger on the innermost ridge 34A, and the covering is more reliably performed. The tool 1 can be pulled up to be worn without distortion. Further, even if water infiltrates through the

ridges

31A, 32A, and 33A, the ridge 34A can reliably prevent the water from entering.

The waterproof portion 30A shown in FIG. 3 (e) and FIG. 3 (f) is an example in which the shape of the ridge portion is changed. That is, although the cross-sectional shape of the ridges 31A to 34A of the waterproof part 30A shown in FIG. 3A to FIG. 3D is substantially square, FIG. 3E and FIG. The cross section of the ridges 31A to 33A of the waterproof portion 30A shown is shaped like a mountain in which the width of the base end is wide and the width of the tip is narrow. FIG. 3 (e) shows an example in which the cross sections of the ridges 31A to 33A are linearly contracted, and FIG. 3 (f) shows an example in which the cross sections of the ridges 31A to 33A are curvilinearly reduced.

If the cross-sectional shape of the ridge portion is a mountain-like shape with a wide base end portion and a narrow tip portion width, the ridge portion will not fall when worn. That is, since the covering tool 1 is elastic and has a diameter smaller than that of the calf, it can be pulled upward while being in close contact with the shin and the calf when worn. At this time, as shown in FIG. 3 (a) to FIG. 3 (d), if the cross-sectional shape of the ridges is substantially square, the ridges may fall down. When the ridges fall downward, the force with which the ridges are pressed against the calves weakens, so the waterproof function as a waterproof part can not be exhibited. In this embodiment, since the cross-sectional shape of the ridge portion is a mountain shape having a wide base end portion and a narrow tip end portion, the ridge portion does not fall downward when worn, and the waterproof effect is stably achieved. Can be demonstrated.

In the example shown in FIG. 3 (e), the cross sections of the ridges 31A to 33A are linearly reduced and have a substantially triangular cross section. In this case, it is possible to prevent the convex ridge portion from falling and failing to exhibit the waterproof function as described above, and also to exhibit a reliable waterproof effect by the convex ridge portion. That is, since the cross sections of the ridges 31A to 33A have a substantially triangular shape, it is easy to bite into the skin, and it is possible to more reliably prevent water from entering.

In the example shown in FIG. 3F, the cross sections of the ridges 31A to 33A are curvilinearly reduced, and the cross-sectional shape at the tip has a substantially semicircular shape or a substantially parabolic shape. In this case, it is possible to prevent the projection from falling and failing to exhibit the waterproof function as described above, and to obtain more comfortable wearing. That is, since the tip of the ridge is a smooth curved surface, there is little stimulus given to the skin, and the ridge can fall and exhibit a waterproof function while maintaining a comfortable wearability that can withstand long-time wearing It can prevent losing.

The mountain-shaped shapes as shown in FIG. 3 (e) and FIG. 3 (f) can be used in combination with the pattern of the ridges shown in FIGS. 3 (a) to 3 (d). Alternatively, it is also possible to make the heights of the plurality of convex streaks the same, and to make only the cross-sectional shape into a mountain shape as shown in FIGS. 3 (e) and 3 (f).

[Thickness 50]
In the example shown in FIGS. 1 to 3, although the structure of the waterproof portion 30A has a structure in which the ridges are provided on the inner peripheral surface near the upper opening 10A, the outer peripheral surface near the upper opening 10A as shown in FIG. It is good also as composition which gives thick part 50 to. That is, by forming the outer peripheral surface of the region provided with the ridges 31A to 34A to be thicker than the portion constituting the entire covering tool 1, it is possible to make the upper opening 10A difficult to deform. More powerfully, it is possible to prevent the entry of water from the outside.

Such thick portions 50 on the outer peripheral surface in the vicinity of the upper opening 10A may be provided in combination with the ridges 31A to 34A on the inner surface, or the ridges 31A to 34A are not provided but are used alone It is also good. In the case where the thick portion 50 is provided independently without providing the ridges 31A to 34A, the structure is further simplified, so that the covering tool can maintain the waterproof function while suppressing the manufacturing cost. It can be done.

Further, in the present embodiment, the thick portion 50 is provided only in the outer peripheral portion of the upper opening 10A, but the thick portion 50 may be provided in the outer peripheral portion of the lower opening 10B.

Here, as shown in FIG. 4, in the case where the thick portion 50 is provided on the outer peripheral surface in the vicinity of the upper opening 10A, the support portion 20 and the thick portion 50 have the same thickness. And the thick portion 50 may be connected without any step.

In the above embodiment, the thickness of the support portion 20 is configured to have the same thickness both in the portion formed in the center in the vertical direction and in the portion formed in the V shape in the left and right However, as shown in FIG. 5, it is also possible to adopt a configuration in which the thickness gradually increases from the bottom to the top. By configuring in this way, the support force can be configured to gradually increase upward, so that a covering device having a function of effectively pushing up the water containing lymph fluid by using the support force gradient. It can be done.

In the above embodiment, an example is shown in which the covering tool 1 is configured to be worn on a calf, but not limited to the calf, knees, thighs, abdomen, upper arms, elbows, wrists, heels, Ankle, face, neck, neck and around the nail, Edema improvement effect, skin care effect, moisturizing effect, sweating effect, sweat recovery effect, fatigue recovery effect, slimming effect and dirt removal effect of pores Any one or more kinds of cosmetic effects selected from The present invention can be applied to any part of the body as long as it is a part desired to be obtained.

Possible coating tools can be provided.

EXAMPLES Hereinafter, the present invention will be specifically described by way of examples, but the present invention is not limited thereto.

<Test example>
The covering device 1 of the shape specified by FIG. 1 and FIG. 2 was attached to the calf of an adult male. The Type E durometer hardness of the covering tool 1 is 5 or more, the elongation at cutting is 650% or more, the tensile strength is 0.208 MPa or more, and the tensile stress at 100% elongation is 0.0163 MPa, 200 The tensile stress at% elongation was 0.0244 MPa.

The type E durometer hardness was measured in accordance with JIS K6253-3: 2012 "Vulcanized rubber and thermoplastic rubber-Determination of hardness-Part 3: Durometer hardness". As a measuring apparatus, Asker rubber hardness system (durometer) E type manufactured by Kobunshi Keiki Co., Ltd. was used.

Elongation at break, tensile strength and tensile stress were measured in accordance with JIS K6251: 2017 "Vulcanized rubber and thermoplastic rubber-Determination of tensile properties". The shape of the test piece was a dumbbell-shaped No. 2 type, and the measuring device used was a precision universal testing machine autograph EZ-LX 1kN manufactured by Shimadzu Corporation. The capacity of the device is 1 kN in load cell type.

In addition, the size of the covering tool 1 before mounting the covering tool 1 on an adult male calf was longitudinal (axial length) 145 mm and circumferential length 160 mm. On the other hand, when wearing the covering tool 1 under the knees and ankles of an adult male, the size of the covering tool 1 during wearing is vertical (axial length of calf) 400 mm, circumferential length (peripheral length of calf) ) 600 mm.

Thereafter, with the covering tool 1 attached, the body bath was performed for 60 minutes in a state where the calves were placed in hot water in a bath adjusted to a hot water temperature of 42 ° C. As a result, after 10 minutes, the perspiration starts to be felt, the presence of sweat in the inside of the covering device 1 starts to be felt, and after 30 minutes, there is already a large amount of perspiration. Moreover, the hot water did not infiltrate into the inside of the coating tool 1 through 60 minutes.

<Discussion>
The covering tool 1 is formed of a molded body of a material having stretchability and waterproofness, has a type E durometer hardness of 5 or more, and has a cylindrical shape having a diameter smaller than a part of the human body to be worn by the molded body. Is formed. Therefore, not only the adhesion between the human body and the beauty tool is high, but also it is configured to apply a predetermined pressure when worn on a part of the human body. The pressure can be stably applied to the part, and as a result, a cosmetic effect can be provided.

In addition, the elongation at the time of cutting of the covering tool 1 is 650% or more, and the covering tool 1 is made as thin as possible after wearing it on the human body while giving a predetermined thickness to the covering tool 1 before wearing it on the human body can do. If the covering tool 1 before mounting is too thin, it affects the mounting ease of the covering tool 1, but since the covering tool 1 has a sufficient tensile elongation at break, it has a predetermined thickness on the covering tool 1 before mounting on the human body The ease of attachment can be secured by applying.

On the other hand, the covering tool 1 can be made as thin as possible after wearing on the human body. Since the thickness of the covering tool 1 is sufficiently thin, it is possible to minimize the heat loss due to the material constituting the covering tool 1, and the heat possessed by the hot water in the bath when bathing with the covering tool 1 worn It can be transmitted to the wearer as it is, and a higher warm bath effect can be obtained.

From the above, the covering device 1 can be applied to various cosmetic effects, for example, an edema prevention effect, a skin care effect, a moisturizing effect, a sweating effect, a fatigue recovery effect, a slimming effect and a pore removing effect.

Moreover, since the tensile strength of the coating | covering tool 1 is about 0.208 Mpa, it has the high durability which is not destroyed even if it utilizes it in multiple times. In addition, beauty tools are often used when taking a bath, and it is not assumed that the same beauty tool is repeatedly used too many times from the viewpoint of hygiene, and the wearer is Although it is preferable to replace the cosmetic device with a new cosmetic device after using the same cosmetic device once or several times, the tensile strength of the covering device 1 is not too large, so that it can be used repeatedly and cost effectively. Excellent.

In addition, since the tensile stress at 100% elongation of the covering tool 1 is 0.0163 MPa and the tensile stress at 200% elongation is 0.0244 MPa, it is possible to secure the anti-displacement property of the covering tool 1 and a good fit. Also, it is possible to prevent the wearer from being tightened too much, being excessively compressed, or leaving a mark on the mounting point when the covering tool 1 is removed.
