Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a Guasha tool used for so-called Guasha therapy, in which a person's skin surface or the like is rubbed to improve blood circulation, and a method for manufacturing the Guasha tool.

A large amount of so-called kucha clay exists on the main island of Okinawa, and it has been used since ancient times as pottery (ceramic products) such as red roof tiles and Tsuboya pottery.

Kucha clay, for example, consists of ancient rocks that form mountains several hundred meters above sea level in the northern part of the main island of Okinawa, and strata formed by erosion of hilly soil. collected from high clay layers. This stratum is an older and younger volcanic rock belt, an old stratum existing on the extension of the Kirishima volcanic belt, and unlike the newer strata in the central and southern part of the main island of Okinawa, the degree of erosion and weathering is said to be higher. . On the main island of Okinawa, it can be collected not only in the northern region but also in the central and southern regions at quarries and the like.

The color tone of this kucha clay is a pale yellow-brown, fine-granular, acidic clay layer with high water retention. In addition, this kucha clay has a unique stickiness, and the particles are fine and uniform. The particle size is 100 μm or less. Therefore, as mentioned above, it is difficult to crack when made into ceramics and has good heat resistance, so it has been useful as a material for pottery (ceramic products) (however, it is difficult to refine or handle). Therefore, in recent years, it is no longer used as a material for ceramics.)
Kucha clay has high heat resistance and does not melt even at 1400°C.

In recent years, various new applications utilizing its properties have been investigated, and in particular, it has become widely used as a mud pack for beautifying the skin or for cosmetics. Kucha clay is composed mainly of fine particles of 100 μm or less as described above, and the fine particles have high chemical adsorption and abrasive properties. Therefore, when used as a mud pack on the surface of human skin, it is possible to remove dirt from the skin such as keratin. In addition, when used on the scalp, it is possible to remove excess oil and fat components or proteins from the scalp, prevent hair loss, and impart moistness to the hair.

In addition, the mud pack is not limited to Kucha clay, and there is known a pack agent made by pulverizing and powdering adsorptive mudstone that has accumulated volcanic ash and adding water to form a paste (see, for example, Patent Document 1). ).

JP-A-9-124454

The mud pack disclosed in Patent Document 1 is creamy, and each time the user uses the mud pack, the user picks up the mud pack and thinly spreads it over the target site. Therefore, it can be said that the handleability at the time of use is poor and there is room for improvement.

By the way, in the beauty industry, in addition to the aforementioned mud pack using kucha clay, a health therapy called Guasha therapy is also widely known.

According to the Japan Kassa Association (https://j-kassa.jp/) regarding Guasha therapy, Guasha's "Kassa" is a folk remedy that has been practiced in China for 2,500 years. It is said to be the origin, and ``katsu'' means to scrape, and ``sa'' refers to stagnant blood that cannot move. In addition, the Japan Kasa Association says, ``By rubbing and stimulating the meridians and reflex areas of the skin with a special board, pressure is applied to the capillaries to push out blood toxins to the surface of the skin and improve the flow of the meridians. What to do. It also explains that special equipment (hereinafter referred to as “Guasha equipment”) is used in Guasha therapy.

As a result of intensive studies, the inventors conceived the present invention based on the above-mentioned Kucha clay and Guasha therapy, and confirmed that the present invention has more advantageous effects than conventional Guasha tools.

The present invention has been made in view of the above-mentioned circumstances, and is easier to handle than mud packs, promotes blood flow in Guasha therapy, and combines the chemical adsorption and abrasiveness of Kucha clay on the skin. To provide a Gussa tool capable of enhancing beauty and skin-beautifying effects, and a method for manufacturing the Gussa tool.

<First embodiment>
A cutting tool 10 according to a first embodiment of the present invention and a method for manufacturing the cutting tool 10 will be described with reference to FIGS. 1 to 8. FIG.

(About the composition of the Guasha tool)
1 and 2, the configuration of a scissors tool 10 according to the present embodiment will be described.
FIG. 1 is a plan view illustrating the appearance of a cutting tool 10 according to this embodiment.
FIG. 2 is a photograph showing an example of the Gussa tool 10 shown in FIG. 1 and general beauty soap (solid soap).

As will be described later, the instrument body 10A of the scissors tool 10 according to the present embodiment is formed in a long and flat shape. Therefore, in the following description, the direction that is parallel to the mounting surface and perpendicularly intersects the longitudinal direction in a state where the cutting tool 10 is mounted on the predetermined mounting surface is also referred to as the "width direction". . In addition, generally, the scissors tool 10 is used for improving the blood circulation of the target part of the body by rubbing the surface of the target part of the body while pressing it.

As shown in FIGS. 1 and 2, the Gussa tool 10 according to the present embodiment is formed in a long flat shape, and is handcrafted as ceramics in a pottery of "Yachimun" Tsuboya pottery, for example. It is a so-called facial device. In the case of this embodiment, the material of the Gussa tool 10 is made only of Kucha clay, which is Okinawan clay. be.
"Yachimun" is a dialect of Okinawa and means pottery and pottery. Since the Ryukyu Dynasty, various items such as pots and jars with strong paintings on thick and thick shapes, Shisa figurines, and red roof tiles have been produced as 'Yachimun'.

Kucha clay is the most commonly found soil in Okinawa Prefecture, and is cement-like hard soil containing 100% clay. In addition, research has clarified that Kucha clay, which has accumulated over many years in the sea of Okinawa, is fine-grained and sticky, and has properties similar to clay found in the Mediterranean Sea and the Dead Sea. Since the Ryukyu Dynasty, women have dried kucha clay and used it as a hair wash, or applied it directly to their face as a pack, making it a familiar beauty product in Okinawa. In addition, kucha clay is excellent in adsorbing dirt on the surface of the skin due to the fineness of its particles, and it is also effective for darkening of pores. In addition, Kucha clay is rich in minerals and has a whitening effect to brighten the dullness of the face.

The Gussa tool 10 of this embodiment is manufactured as a ceramic for a facial device using 100% of the Kucha clay, which is clay from Okinawa.

However, in this embodiment, only Kucha clay is used as the material of the Gussa tool 10, but it is not limited to this. Other materials, for example, other clay materials such as red clay may be mixed to some extent for manufacture. Even in this case, it may be produced from a mixed clay containing a large amount of kucha clay, in other words, a mixed clay containing kucha clay as a main raw material (see later). However, it is preferable to use only Kucha clay as the material for the Gussa tool 10 in terms of beauty and skin beautifying effects.

The scissors tool 10 of the present embodiment is formed in an elongated flat shape, and the tool body 10A includes a substantially semicircular arc portion 11 and a tip connected continuously to the substantially semicircular arc portion 11 in a plan view. a detail 12; The tapered portion 12 is formed such that its top portion is inclined (biased) to one side in the width direction of the tool body 10A. Therefore, in the width direction side surfaces 13 and 14, one side surface 13 is formed into a convex curved surface and the other side surface 14 is formed into a concave curved surface. In other words, the cutting tool 10 of the present embodiment is formed with the substantially semicircular arc portion 11 and the tapered portion 12 as a whole in a shape like a comma-shaped bead or a drop. Also, the thickness of the tool main body 10A is set to be 10 mm or less, more preferably in the range of 8 mm to 9 mm, as will be described later.

As described above, the Gussa tool 10 of the present embodiment is a pottery that is fired in an unglazed state using only Kucha clay, which is clay from Okinawa, as a material. Since it is fired in an unglazed state, its surface is physically porous. Moreover, as described above, the utensil body 10A is made of 100% kucha clay, and the kucha clay as a material has chemical adsorption and abrasive properties on the skin. Therefore, when the device main body 10A is pressed against the skin surface of the target site of the user, it promotes blood circulation in the target site and at the same time absorbs sebum on the skin surface or removes keratin from the skin surface to remove dirt. It is possible to remove it.

That is, when the user uses the Gussa tool 10 for face washing, etc., the skin surface is removed from both sides 13 and 10A of the utensil main body 10A of the Gussa tool 10 while absorbing sebum or removing old keratin to remove dirt. By pressing with one of the convex or concave curved surfaces of 14, it is possible to obtain the effect of Guasha therapy. By using the Gussa tool 10 of the present embodiment when washing the face, it can be said that the beauty method can be performed every day while shortening the time. In addition, as will be described later, the kucha clay Guasha tool 10 is manufactured as ceramics, and its unique moderate hardness as ceramics can massage facial muscles and suppress swelling and sagging.

(About the manufacturing method of Guasha tools)
3 to 8, a method for manufacturing the scissors tool 10 according to the present embodiment will be described. FIG. 3 is a process chart illustrating the manufacturing process of the scissors tool 10 according to the embodiment of the present invention. FIG. 4 is a photograph illustrating the clay drying step S2 shown in FIG. FIG. 5 is a photograph illustrating the die-cutting step S5 shown in FIG. FIG. 6 is a photograph illustrating the blanking body drying step S6 shown in FIG. FIG. 7 is a photograph illustrating the baking step S7 shown in FIG. FIG. 8 is a photograph illustrating the cooling step S8 shown in FIG.
Note that the photograph of the firing kiln shown in FIG. 7 shows a state in which ceramics other than the Gussa tool 10 of the present embodiment are also being fired, and the ceramics other than the Gussa tool 10 of the present embodiment are arranged at the top. ing.

As shown in FIG. 3, the manufacturing method (manufacturing process) of the Gussa tool 10 according to the present embodiment includes a refining process S1 (an example of a first process) and a clay drying process S2 (an example of a second process). , a vacuum kneading step S3, a rolling step S4 (an example of the third step), a blanking step S5 (an example of the fourth step), a blanking body drying step S6, and a baking step S7 (fifth (an example of a sixth step), a cooling step S8, and a polishing step S9 (an example of a seventh step). These steps are performed in the order of this description.

In the refining step S1, the collected kucha clay is refined to remove impurities. Specifically, Kucha clay collected from a soil quarry or the like in a region such as the northern part or the central and southern part of Okinawa Prefecture and transported is dried as the original soil for about several days (for example, 2 or 3 days). Then, the dried original kucha clay is crushed by a striking tool such as a hammer, put into a container such as a resin bucket together with a predetermined amount of water, and the supernatant liquid is drained. As a result, impurities contained in the original Kucha clay are removed. Further, the kucha clay to which water has been added is agitated by a stirrer or the like to form a colloid having a predetermined viscosity. The colloidal Kucha clay is filtered through a mesh. Since the grain size of kucha clay is very small, the mesh size is finely set according to the grain size to further remove impurities. Thus, the Kucha clay is refined through the refining step S1.

In the clay drying step S2, the kucha clay refined in the refining step S1 is placed on a plate-shaped diatomaceous earth and dried in the sun (see FIG. 4). At this time, a large number of plate-like diatomaceous earths are prepared and laid widely on a predetermined surface without gaps. In this way, the Kucha clay is dried and moderately dehydrated for hours to days. After the clay drying step S2, a vacuum clay kneading step S3 is performed.

In the vacuum kneading step S3, the dried kucha clay is put into a vacuum kneading device and evacuated to remove the air contained therein (air is removed). At the same time, the Kucha clay is kneaded by a vacuum type kneading device, molded into a cylindrical shape, and discharged. This molding facilitates the handling of the kucha clay in subsequent processes. Also, at this time, no materials other than Kucha clay are mixed. Therefore, a tool blanking body 10B, which will be described later, is molded using only Kucha clay as a material.

As described above, in the present embodiment, only Kucha clay is used as the material of the Gussa tool 10, but the present invention is not limited to this. It may be produced from a mixed clay containing kucha clay as a main raw material. However, considering the beauty and skin beautifying effects, it is preferable to manufacture only from kucha clay.

In the rolling step S4, an apparatus having cylindrical rolling rollers, such as a Tatara plate making machine, is used to form the Kucha clay into a paste plate having a uniform thickness. At this time, the thickness is set to 10 mm or less, more preferably in the range of 8 mm to 9 mm. Based on this thickness, the thickness of the tool body 10A of the final cutting tool 10 is set to 10 mm or less.

In the die-cutting step S5, the paste plate-like Kucha clay is die-cut by a mold (form) to obtain a plurality of tool die-cutting bodies 10B (see FIG. 5). The tool blank 10B is chamfered on its front and back peripheral edges with, for example, a sponge with water tightly squeezed. As a result of this chamfering, the peripheral edge of the tool die-cutting body 10B is formed to draw a gently curved surface protruding outward, such as an R curved surface. Further, in the die-cutting step S5, a sponge is used to slidably contact the surface of each of the plurality of tool-cutting bodies 10B that have been cut out in such a manner so as to rub the surface to perform final molding.
The formwork is formed so as to correspond to the shape of each tool blank 10B so as to have a substantially drop-like shape, as described above.

In the die-cut body drying step S6, the tool die-cut bodies 10B whose surfaces are slidably contacted with a sponge and whose peripheral edges are chamfered are arranged on, for example, a wooden board and dried (see FIG. 6). At this time, these tool blanks 10B are turned upside down or their arrangement on the wooden board is changed so that they are dried as uniformly as possible.

Each of the tool blanks 10B that have been cut out and dried in this way is diagonally shifted with respect to the mounting surface of the mounting table arranged inside the firing kiln in the firing step S7 so as to draw a circle. be arranged in That is, a plurality of tool blanks 10B are placed side by side in a state in which the tool blanks 10B adjacent to each other on the mounting surface partly overlap each other in the thickness direction and support each other. At this time, when one circle is defined as one layer, the plurality of tool blanks 10B have a plurality of layers (two layers in this embodiment) and are stacked vertically. In addition, a plurality of mounting tables are prepared, and each of the tool blanks 10B stacked in a plurality of layers is arranged on each of the mounting tables. Due to this arrangement, the plurality of tool blanks 10B are further arranged in multiple stages in the vertical direction within the firing kiln.
Although an electric kiln is used as the firing kiln in this embodiment, the kiln is not limited to this. For example, a firewood kiln or the like may be used as appropriate.

Further, in the firing step S7, as described above, the plurality of tool blanks 10B arranged in multiple stages in the firing kiln are heated and fired by the firing kiln (see FIG. 7). At this time, the tool blank 10B is fired in an unglazed state without being coated with glaze during firing.

In addition, in this embodiment, the heating for the firing is raised from room temperature to 560 degrees, performed at this 560 degrees for 420 minutes, further raised from this 560 degrees to 800 degrees, and performed at this 800 degrees for 90 minutes. . By such temperature control, a plurality of tool die-cutting bodies 10B are sintered to become ceramics and become the cutting tool 10 of the present embodiment. In the cooling step S8 after firing, the plurality of cutting tools 10 are left to cool inside the firing kiln for, for example, several days (two days in this embodiment) (see FIG. 8).

In the polishing step S9, the unglazed Gussa tool 10 is taken out from the firing kiln in a cooled state, and is polished by removing burrs on its surface or peripheral edge using a file or the like. By polishing the surface of the Gussa tool 10 that has been fired in an unglazed state, it is possible to increase the porosity of the surface.

Through such a process, it is possible to efficiently obtain the Gussa tool 10 of the present embodiment as ceramics made by baking Kucha clay, which is Okinawan clay, in an unglazed state. That is, the scissors tool 10 of the present embodiment is completed in an unglazed state, and when this completed tool body 10A is pressed against the skin surface of the target site of the user, it promotes blood circulation in the target site. It becomes possible to remove dirt by adsorbing sebum on the surface of the skin or removing keratin.

(・How to use the Guasha tool of this embodiment)
