DETAILED DESCRIPTION OF THE INVENTION

[0008] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, unless otherwise specified, the components, types, combinations, shapes, relative positions, etc. described in each embodiment are merely illustrative examples and do not limit the scope of the present invention.

[0009] <Overview of Massage Tool 1> FIG. 1(a) is a perspective view showing a massage tool 1 according to a first embodiment, FIG. 1(b) is a plan view of the massage tool 1, and FIG. 1(c) is a cross-sectional view of the massage tool 1 taken along line AA. The massage tool 1 shown in Figures 1(a) to (c) comprises a main body 10 that comes into contact with the area to be massaged, and a gripping portion 20 that is integral with the main body 10, with a connecting portion 23 (part) embedded inside the main body 10 and a constricted portion 22 (other part) protruding outward from the main body 10. The main body 10 of the massage tool 1 is made of a gel that uses water as a dispersion medium. For example, in the massage tool 1 according to the first embodiment, the gel is made of a gel that uses agar as a dispersoid and water as a dispersion medium. Because the main body 10 is made of a gel that uses water as a dispersion medium, water is retained on the surface of the main body 10.

[0010] When using the massage tool 1 according to this embodiment, the user holds the grip portion 20 with their fingers, brings the main body 10 into contact with the area of ​​the body to be massaged, and then applies pressure and rubs the area with the main body 10. As the top surface of the massage tool 1 is uneven, rubbing the main body 10 against the area to be massaged stimulates and promotes blood flow. With this massage tool 1, when the main body 10 is brought into contact with the area to be massaged, the water held on the surface of the main body 10 adheres to the surface of the area to be massaged, moistening it. Furthermore, when the area is rubbed with the main body 10, the water held on the surface of the main body 10 reduces the friction between the main body 10 and the body. As a result, the area to be massaged can be moisturized and given a moderate stimulation.

[0011] <About the main unit 10> The following describes in detail the massage tool 1. First, we will explain the main body 10 of the massage tool 1. As shown in Fig. 1, the main body 10 of the massage tool 1 has an outline that is approximately trapezoidal when viewed from the front and back and from both the left and right sides. The upper surface 10a of the main body 10 is shaped like a plum blossom, and a small, hemispherical protrusion 10b resembling a pistil is provided in the center of the upper surface 10a. Five approximately V-shaped grooves 10c are formed in a straight line at 72-degree circumferential intervals from the small protrusion 10b in the outer diameter direction. The fan-shaped portions 10d located between the five grooves 10c are resembling petals. The upper surface of each fan-shaped portion 10d is arc-shaped, and a small, hemispherical protrusion 10e is provided near the center of the upper surface 10a. In this way, the upper surface 10a of the main body 10 has unevenness, so when the upper surface 10a of the main body 10 is brought into contact with the area to be massaged and rubbed along the surface of the area, stimulation is given and blood flow is promoted.

[0012] The main body 10 of the massage tool 1 is made of an uncolored gel with agar as a dispersoid and water as a dispersion medium. In this embodiment, the main body 10 has a water content of 98% (agar concentration of 2.0% by weight) and a gel strength (jelly strength) of 2300 g / cm 2 That's all. The gel strength was measured in accordance with the "Nissan-sui method" (JIS K 8263). In this method, an agar solution of a predetermined concentration (for example, a 1.5 wt % sol) is prepared, and the gel is solidified by leaving it at 20°C for 15 hours. The gel is then set in a strength measuring instrument, and a load is applied to the surface of the gel using the load axis of the strength measuring instrument. 2 The maximum weight (g) that can be withstood for 20 seconds per unit weight is measured, and the measured maximum weight is taken as the gel strength.

[0013] The agar used was "Kalicorican" (registered trademark) manufactured by Ina Food Industry Co., Ltd. This agar is made from at least one seaweed from the genera Gelidium, Gracilaria, and Obsidiana, and has a gel strength of 1500 g / cm at an agar concentration of 1.5 wt %. 2 The weight average molecular weight is 600,000 or more, and the molecular weight distribution (Mw / Mn) is 13 or less. Mw represents the weight average molecular weight, and Mn represents the number average molecular weight. As a specific example, the agar has a gel strength of 14 g / cm at a water content of 99.9% (agar concentration of 0.1% by weight). 2 The gel strength at a water content of 99.8% (agar concentration of 0.2% by weight) is 119 g / cm 2 The gel strength at a water content of 99.7% (agar concentration of 0.3% by weight) is 250 g / cm 2 is. Furthermore, the agar has a gel strength of 500 g / cm at a water content of 99.5% (agar concentration of 0.5 wt%). 2 ~700g / cm 2 The gel strength at a water content of 99.2% (agar concentration of 0.8% by weight) is 650 g / cm 2 ~850g / cm 2 The gel strength at a water content of 99.0% (agar concentration of 0.1% by weight) is 800 g / cm 2 ~1000g / cm 2 The gel strength at a water content of 98.5% (agar concentration of 1.5% by weight) is 1850 g / cm 2 ~2300g / cm 2 is.

[0014] From these values, it can be said that the moisture content of the main body 10 should be 98.0% or more and 99.9% or less (agar concentration: 2.0% by weight or less and 0.1% by weight or more). In other words, by adjusting the moisture content of the main body 10 within this range, it is possible to provide moisture and a moderate stimulation to the area to be massaged. The strength of the stimulation applied to the target area of ​​the massage can also be adjusted according to the water content of main body 10. For example, by setting the water content of main body 10 to be 98.0% or more and 99.5% or less, the stimulation applied to the target area can be stronger than when the water content is 99.7% or more and 99.9% or less. Furthermore, gelled agar can be converted into a sol by heating, and the temperature at which the agar becomes a sol is 80° C. or higher. Therefore, the massage tool 1 of this embodiment can be used even while taking a bath.

[0015] The main body 10 is not limited to a gel containing agar as a dispersoid, as long as it is made of a gel containing water as a dispersoid. For example, the main body 10 may be made of a gel containing agar and a water-soluble polysaccharide, such as konjac (glucomannan), as a dispersoid.

[0016] <Regarding the grip portion 20> Next, the grip portion 20 will be described. Fig. 2(a) is a plan view of the grip portion 20, Fig. 2(b) is a BB cross-sectional view of the grip portion 20, and Fig. 2(c) is a vertical cross-sectional view of the massage tool 1. 2(a) and 2(b), the grip portion 20 is a shaft made of hard plastic. In this embodiment, the grip portion 20 is made of transparent polystyrene resin, but is not limited to this configuration. The grip portion 20 may be made of other types of synthetic resin materials or may be made of a colored material. The gripping portion 20 comprises a bottom plate 21 having a circular bottom surface, a constricted portion 22 extending upward (toward one end in the axial direction) from the center of the bottom plate 21, and a connecting portion 23 that is provided continuously from the upper end (one end in the axial direction) of the constricted portion 22 and is embedded inside the main body 10.

[0017] The constricted portion 22 has a shaft shape with a circular cross section, with the diameter being smallest at the middle portion in the axial direction and gradually increasing toward the upper end (one end) and lower end (the other end) in the axial direction. The connecting portion 23 comprises a lower large diameter portion 24 (second large diameter portion) which extends continuously from the upper end of the constricted portion 22 upward and has a circular cross section, a small diameter portion 25 which extends continuously from the upper end of the lower large diameter portion 24 upward and has a circular cross section with a smaller diameter than the lower large diameter portion 24, and an upper large diameter portion 26 (first large diameter portion) which extends continuously from the upper end of the small diameter portion 25 upward and has a circular cross section with a larger diameter than the lower large diameter portion 24. The upper large diameter portion 26 is provided with a plurality of (four) through holes 27 that pass through the upper large diameter portion 26 in the axial direction. Each through hole 27 has an elliptical shape that is long in the radial direction when viewed from above, and is provided at 90-degree circumferential intervals from the center of the upper large diameter portion 26.

[0018] As shown in Figure 2(c), by providing the through-hole 27 in the upper large diameter portion 26, the main body 10 of the massage tool 1 also fills the inside of the through-hole 27 and the space between the upper large diameter portion 26 and the lower large diameter portion 24. As a result, the main body 10 is less likely to come off the grip portion 20, and the unity of the two can be improved.

[0019] <About the packaging container 30> As described above, the main body 10 of the massage device 1 is made of a gel that uses water as a dispersion medium. For this reason, it is important for the massage device 1 to suppress evaporation of water from the main body 10. Therefore, in this embodiment, the massage tool 1 is sealed inside a highly airtight packaging container 30. Fig. 3 is an exploded perspective view showing the massage tool 1, container body 40, and lid member 50, and Fig. 4 is a perspective view showing the massage tool 1 sealed inside the packaging container 30 together with a preservative solution 60.

[0020] As shown in Figure 3, the packaging container 30 comprises a cup-shaped container body 40 having a side portion 41 and a bottom portion 42, an open top surface, and a flange 44 radially outward from the opening 43, and a sheet-like lid material 50 removably attached to the flange 44 of the container body 40 by welding or the like. In this embodiment, the container body 40 is made of a cup-shaped PET (polyethylene terephthalate), and the lid member 50 is made of OPP (biaxially oriented polypropylene). The container body 40 and the lid member 50 have a transparency that allows the enclosed massage tool 1 to be seen. The packaging container 30 (container body 40, lid member 50) is not limited to the above-mentioned materials. The container body 40 and lid member 50 may be colored so that the insides are not visible.

[0021] As shown in Fig. 4, the massage tool 1 is sealed inside the packaging container 30 together with a preservative solution 60. The amount of the preservative solution 60 is adjusted so that the liquid level is lower than the opening 43 of the container body 40 by a specified height (for example, 2 mm to 3 mm). This is to prevent the preservative solution 60 from spilling from the container body 40 when the lid member 50 is peeled off from the container body 40 during use, which will be described later.

[0022] The preservative solution 60 is uncolored water containing, for example, a preservative, a moisturizer, a solubilizer, and a fragrance. The preservative is added to improve the shelf life of the main body 10 of the massage tool 1, and for example, methylparaben and phenoxyethanol are used. The moisturizer is added to suppress evaporation of water, and for example, a glycol-based moisturizer is used. Adding the moisturizer can suppress drying of the massage area and maintain moisture for a long period of time. The solubilizer is added to dissolve the preservative in water. The fragrance is added to suppress the agar odor. The preservatives and moisturizing agents are merely examples, and other ingredients may be used. In addition, if a water-soluble preservative is used, the solubilizer does not need to be added.

[0023] In this embodiment, the massage tool 1 is sealed inside the packaging container 30, so evaporation of moisture from the main body 10 can be suppressed for a long period of time compared to when it is stored in a comparative example packaging container that is not airtight. In this embodiment, the massage tool 1 is sealed inside the packaging container 30 together with the preservative liquid 60, so that evaporation of moisture from the main body 10 can be suppressed compared to when the massage tool 1 is sealed inside the airtight packaging container 30 without the preservative liquid 60. In this embodiment, the massage tool 1 is sealed inside the packaging container 30 together with the preservative liquid 60, so that the massage tool 1 can be stored for a longer period of time than when it is sealed inside the packaging container 30 together with water that does not contain preservatives or moisturizers.

[0024] <How to use massage tool 1> Next, there will be explained the procedure for using the massage tool 1. Fig. 5 is a diagram showing the procedure for using the massage tool 1, and Fig. 6 is a diagram showing the massage tool 1 being held by the user's fingers FN. As shown in Figure 5(a), first, the lid member 50 of the packaging container 30 is peeled off from the container body 40. As described above, the upper surface of the storage solution 60 is lower than the opening 43 of the container body 40 by a specified height, so the storage solution 60 is unlikely to spill from the container body 40 when the lid member 50 is peeled off. Furthermore, because the storage solution 60 is colorless and transparent, even if it does spill out of the container body 40, it is possible to prevent the inconvenience of staining clothes, hands, etc. As shown in FIG. 5(b), after the lid member 50 is peeled off from the container body 40, the container body 40 is tilted to discharge the preservative solution 60 from the opening 43 of the container body 40. As shown in FIG. 5(c), after the preservative solution 60 has been discharged from the container body 40, the massage tool 1 is taken out of the container body 40 by pinching the bottom plate 21 of the grip portion 20 with the fingertips. As shown in FIG. 6, the massage tool 1 is grasped by pinching the constricted portion 22 of the grip portion 20 between two fingers FN, and the top surface of the main body 10 is brought into contact with the area to be massaged and rubbed along the surface of the area.

[0025] <About the manufacturing method of the massage tool 1> Next, a description will be given of a method for manufacturing the massage tool 1. Figures 7 and 8 are diagrams showing a method for manufacturing the massage tool 1. As shown in FIG. 7(a), first, a container body 40 is prepared (preparation step). As shown in FIG. 7(b), after the container body 40 is prepared, a specified amount of sol 11 (the base of the body 10) obtained by heating a mixture of powdered agar and water is poured into the container body 40 through an opening 43 (sol pouring step). The sol 11 is poured using, for example, a tube pump. The amount poured can be controlled by any method. For example, the amount poured of sol 11 can be controlled using a weighing scale or by the liquid level of sol 11.

[0026] 7(c), after a specified amount of sol 11 is poured into the container body 40, before the sol 11 gels, the position of the gripping part 20 is fixed with the connecting part 23 penetrated into the sol 11 (fixing step). In this embodiment, the connecting part 23 is penetrated into the sol 11 with the bottom plate 21 of the gripping part 20 held by the holder 70. The holder 70 includes, for example, a holder main body 71 having a flange 72 on its peripheral edge, and a pair of claw members 73 integrally formed with the holder main body 71. In this embodiment, the holder 70 is made of synthetic resin, and the claw members 73 are provided so as to be displaceable relative to the holder main body 71. As a result, a locking portion 73a provided at the tip of the claw member 73 opens and closes, thereby locking and unlocking the bottom plate 21 of the grip portion 20. In this holder 70, the holder body 71 can be placed over the top surface of the container body 40 while the outer peripheral edge of the bottom plate 21 is engaged by the engaging portion 73a, thereby positioning the gripping portion 20 at a predetermined position inside the container body 40. 7(c) is maintained until the sol 11 gels. That is, the container body 40, the sol 11, and the gripping part 20 are left standing until the sol 11 gels and the body 10 is produced inside the container body 40 (standing step).

[0027] As shown in FIG. 8( a ), after the sol 11 has gelled inside the container body 40 to produce the body 10 , the holder 70 is removed from the container body 40 . As shown in FIG. 8(b), a predetermined amount of preservation solution 60 is poured into the container body 40 (water pouring step). As described above, the preservation solution 60 is, for example, water containing a preservative, a moisturizer, and a solubilizer. The preservation solution 60 is also poured, for example, using a tube pump. The amount poured can be controlled by any method. For example, the amount poured can be controlled by a weighing scale or by the liquid level of the preservation solution 60. As shown in Figure 8(c), after pouring a specified amount of preservative solution 60, a sheet-like lid material 50 is attached to the upper surface (flange 44) of container body 40, and opening 43 is sealed with lid material 50 (sealing step). Lid material 50 is joined to flange 44 by, for example, heat sealing, but joining methods other than heat sealing may be used as long as it can be peeled off from flange 44. For example, it may be joined using an adhesive.

[0028] The massaging tool 1 of this embodiment manufactured by the above-described procedure can be manufactured efficiently because the container body 40 is also used as a mold for molding the body 10 of the massaging tool 1 into a desired shape. Furthermore, by varying the shape of the container body 40, it is possible to produce a plurality of types of massage tools 1 having bodies 10 with different shapes. For example, by varying the shape of the container body 40, it is possible to produce a first modified massage tool 1A shown in Fig. 9(a) and a second modified massage tool 1B shown in Fig. 9(b). The first modified massage tool 1A is characterized in that the body 10 is shaped like a bivalve shell, and the second modified massage tool 1B is characterized in that the body 10 is shaped like a lily flower.

[0029] <About modified examples> In the above-described embodiment, the main body 10 of the massage tool 1 is made of agar (dispersoid) and water (dispersion medium), but the main body 10 may be made of a gel using water as the dispersion medium. For example, the main body 10 may be made of a gel using a polysaccharide such as agar or konjac (glucomannan) as the dispersoid and water as the dispersion medium. When konjac is used as the dispersoid, for example, a sol made from konjac flour and water may be made alkaline, and gelled inside the packaging container 30 .

[0030] In the above-described embodiment, the main body 10 is uncolored, but it may be colored. Similarly, the preservative solution 60 may be colored. In the above-described embodiment, the massage tool 1 was sealed in the packaging container 30 together with the preservative solution 60, but the massage tool 1 and pure water may also be sealed in the packaging container 30, or only the massage tool 1 may be sealed in the packaging container 30. In the above-described embodiment, the container body 40 and the lid member 50 are used as the packaging container 30, but the present invention is not limited to this configuration. For example, a sealed bag with a zipper may be used as the packaging container. In the above embodiment, water containing a preservative, a moisturizer, a solubilizer, and a fragrance is exemplified as the preservative solution 60, but the preservative solution 60 is not limited to this configuration. The preservative solution 60 may be water containing at least a preservative, and the moisturizer and fragrance may be added as needed.
