Description

Pads for cosmetics and liquid cosmetics and liquid cosmetic impregnated bodies

The present invention relates to a cosmetic containing a liquid cosmetic such as a liquid foundation, a pad impregnated with the liquid cosmetic, and a liquid cosmetic impregnated body in which the pad is impregnated with the liquid cosmetic.

FIG. 11 shows an example of conventional cosmetics. The liquid foundation is impregnated in the pad 200. The pad 200 is made of a soft sponge. The pad 200 is housed in the container 201. The container 201 has an opening 202. The upper surface of the pad 200 is exposed from the opening 202. The foundation is taken out from the pad 200 by pressing a puff (not shown) against the upper surface of the pad 200. However, when the puff is pressed against the pad 200, a large amount of foundation tends to be transferred to the puff.

On the other hand, Patent Document 1 below proposes a configuration in which the screen net is placed close to the upper surface of the pad by fixing the screen net to the frame of the container. It is explained that this configuration adjusts the amount of foundation taken out of the pad.

FIG. 12A schematically shows a structure in which the screen net 101 is fixed to the frame 100. As shown in FIG. 12B, when the screen net 101 is pushed downward with a puff (not shown), the screen net 101 is deformed downward and the pad 102 is deformed. The foundation moves from the pad 102 to the puff via the screen net 101. However, the foundation tends to escape to the peripheral edge of the pad 102, and the foundation tends to remain on the peripheral edge of the pad 102. Further, since the screen net 101 is fixed to the frame 100, there is a limit to the extension of the screen net 101. Therefore, as shown in FIG. 12C, it is difficult to push the peripheral edge of the pad 102, and it is difficult to remove the foundation remaining on the peripheral edge of the pad 102 with a puff.

The present invention provides cosmetics, a pad for liquid cosmetics, and a liquid cosmetic impregnated body, which can easily adjust the amount of liquid cosmetics taken out and reduce the amount of liquid cosmetics left behind. Is an issue.

The cosmetic product according to the present invention includes a pad and an exterior body. The pad is impregnated with liquid cosmetics. The pad is housed in the exterior. The exterior body has an opening for exposing the upper surface of the pad. The pad includes a pad body and a mesh cover. The pad body is made of a fibrous body having cushioning properties. The mesh cover consists of a mesh sheet. The mesh cover wraps the pad body. The mesh cover covers at least the entire upper surface of the pad body. The ends of the fibers on the top surface of the pad body are entwined with the mesh cover. The mesh cover is locked to the upper surface of the pad body.

According to this configuration, the pad body is made of a fibrous body having cushioning properties. Compared to sponges, fibrous bodies with cushioning properties are less likely to leave liquid cosmetics inside. The liquid cosmetic is transferred to the puff or the like via the mesh cover. Therefore, it is possible to prevent the liquid cosmetic from being excessively taken out from the pad body. Further, since the pad body is wrapped by the mesh cover, the mesh cover follows the deformation of the pad body. Since the pad body and the mesh cover are integrally deformed, it is possible to reduce the amount of liquid cosmetic left behind. Further, the end of the fiber on the upper surface of the pad body is entwined with the mesh cover, and the mesh cover is locked to the upper surface of the pad body. Therefore, the mesh cover does not easily lift from the upper surface of the pad body, and the mesh cover follows the movement of the upper surface of the pad body. That is, the mesh cover is not separated from the upper surface of the pad body, and the upper surface of the pad body and the mesh cover are integrally deformed or restored. Therefore, the liquid cosmetic can be evenly adhered to the puff, and the liquid cosmetic is less left behind. Further, since the upper surface of the pad body and the mesh cover are in close contact with each other, the aesthetics of the upper surface of the pad is excellent.

Preferably, the mesh cover covers at least the upper surface, the entire side surface, and the lower surface of the pad body. According to this configuration, the function of adjusting the amount of the mesh cover removed works effectively. In addition, the amount of leftover liquid cosmetics is further reduced.

Further, the pad for liquid cosmetics according to the present invention is a pad impregnated with liquid cosmetics. The pad includes a pad body and a mesh cover. The pad body is made of a fibrous body having cushioning properties. The mesh cover consists of a mesh sheet. The mesh cover wraps the pad body. The mesh cover covers at least the entire upper surface of the pad body. The ends of the fibers on the top surface of the pad body are entwined with the mesh cover. The mesh cover is locked to the upper surface of the pad body.

Further, the liquid cosmetic impregnated body according to the present invention is the pad impregnated with the liquid cosmetic.

As described above, the amount of liquid cosmetics taken out can be easily adjusted, and the amount of liquid cosmetics left behind can be reduced.

<Pad 2>
The pad 2 holds the liquid cosmetic. The pad 2 is impregnated with liquid cosmetics. The pad 2 is soft. The pad 2 can be easily deformed. The shape of the pad 2 corresponds to the shape of the accommodating portion of the inner container body 10. As shown in FIG. 2A, in the present embodiment, the pad 2 has a circular shape in a plan view. However, the pad 2 may have a rectangular shape in a plan view or the like. In the present embodiment, the pad 2 is a columnar shape in which the dimension (thickness) in the direction of the center line is smaller than the diameter. The diameter of the pad 2 is, for example, about 3 to 15 cm. The thickness of the pad 2 is, for example, about 0.5 to 5 cm. The pad 2 includes a pad body 30 for holding the liquid cosmetics and a mesh cover 31 for adjusting the amount of the liquid cosmetics taken out.

The pad body 30 is the main part of the pad 2. The pad body 30 is impregnated with liquid cosmetics. As shown in FIG. 2B, in the present embodiment, the pad body 30 has a circular shape in a plan view. The pad body 30 is a columnar shape having a thickness smaller than the diameter. However, the pad body 30 may have a rectangular shape in a plan view or the like. The pad body 30 has an upper surface 30a, a side surface 30b, and a lower surface 30c. The upper surface 30a and the lower surface 30c of the pad body 30 have a flat circular shape. The side surface 30b of the pad body 30 is a peripheral surface. The diameter of the pad body 30 is, for example, about 3 to 15 cm. The thickness of the pad body 30 is, for example, about 0.5 to 5 cm.

The pad body 30 is made of a fibrous body. The fiber body has a cushioning property. The fibrous body has a structure in which fibers are three-dimensionally intersected like a jungle gym. The fibrous body has a three-dimensional three-dimensional structure. The intersection where the fibers intersect is a contact portion where the fibers are in contact with each other. At the contact portion, the fibers are fused together. The density of the fiber body is, for example, ^{about 6 to 50 kg / m 3} , preferably about 6 to 30 kg / m ³ . The Asker F hardness of the fiber body is preferably about 30 to 60. The Asker F hardness is a value measured at a temperature of 25 ° C. using an Asker rubber hardness tester F type manufactured by Polymer Meter Co., Ltd. The pad body 30 may be a single layer or a multi-layer. When the pad body 30 has multiple layers, it is preferable that the density of the layers constituting the upper surface 30a is higher than the density of the other layers.

The fibers constituting the fiber body may be various, but preferably contain composite fibers. The composite fiber contains two types of resins having different melting temperatures. By melting the resin with the lower melting temperature of the two types of resin, the fibers are fused to each other at the contact portion. The resin having a higher melting temperature is referred to as a high-temperature molten resin, and the resin having a lower melting temperature is referred to as a low-temperature molten resin.

The composite fiber is, for example, a core-sheath type composite fiber, a side-by-side type composite fiber, a sea-island type composite fiber, or the like. A core-sheath type composite fiber is preferable from the viewpoint of efficiently integrating the contact portion between the fibers. When the fibers are crimped by heating, side-by-side composite fibers are preferable.

The core-sheath type composite fiber has a core component which is a core component and a sheath component which covers the core component. A high temperature molten resin is used as the core component. A low-temperature molten resin is used as the sheath component. At the contact portion between the fibers, the composite fibers are firmly integrated with each other by the low-temperature molten resin. The volume ratio of the core component to the sheath component (core component: sheath component) is preferably 30:70 to 70:30.

Examples of the low-temperature molten resin include polyester and thermoplastic elastomer. Specifically, examples of the polyester include polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polyhexamethylene terephthalate, and polytetramethylene terephthalate. Examples of the thermoplastic elastomer include polyester elastomers such as polyethylene terephthalate elastomers, and polyether-ester block copolymers having polyester as a hard segment and poly (alkylene oxide) glycol as a soft segment.

The fineness of the composite fiber is preferably 0.5 to 15 denier, more preferably 1 to 10 denier. When the fineness is in this range, the liquid cosmetics taken into the pad body 30 can be efficiently taken out to the outside. Further, the pad body 30 having excellent mechanical strength can be obtained. The fineness of the fiber is the mass (g) of the fiber (filament) per fiber length of 9000 m.

The fiber length of the composite fiber is preferably about 20 to 150 mm. When the fiber length is in this range, the liquid cosmetics taken into the pad body 30 can be efficiently taken out to the outside, and the pad body 30 having excellent mechanical strength can be obtained. If necessary, the composite fiber may be subjected to processing such as antibacterial processing and antibacterial processing.

The fiber body contains a composite fiber as a constituent fiber. The fibrous body may be composed of only the composite fiber, but may be composed of the composite fiber and other fibers other than the composite fiber. Examples of other fibers include natural fibers such as cotton, hemp and silk, regenerated fibers such as rayon, synthetic fibers and the like, but synthetic fibers are particularly preferable. It is preferable that the composite fiber and the synthetic fiber are fused at the contact portion with each other.

Examples of synthetic fibers include polyester fibers such as polyethylene terephthalate fiber, polybutylene terephthalate fiber, and polytrimethylene terephthalate fiber, polyvinyl chloride fiber, polyvinylidene chloride fiber, polypropylene fiber, polyvinyl alcohol fiber, and nylon 6. Examples thereof include polyamide fibers, polyimide fibers, polyamideimide fibers, and cellulose acetate fibers, but the present invention is not limited to these examples. Each of these fibers may be used alone, or two or more types may be used in combination. Among these synthetic fibers, polyester fibers and polyamide fibers are preferable, and polyester fibers are more preferable. If necessary, the synthetic fiber may be subjected to processing such as antibacterial processing and antibacterial processing.

The melting temperature of the synthetic fiber is preferably 20 ° C. or higher, more preferably 30 ° C. or higher, higher than the melting temperature of the low-temperature molten resin of the composite fiber from the viewpoint of preventing the composite fiber from sagging or lowering the elastic force. .. The melting temperature of the synthetic fiber is 150 to 270 ° C. from the viewpoint of preventing the composite fiber from sagging and efficiently heat-sealing the composite fiber and the synthetic fiber at the contact portion between the composite fiber and the synthetic fiber. It is preferably 160 to 270 ° C., more preferably 160 to 270 ° C. The fineness of the synthetic fiber is preferably 0.5 to 15 denier, more preferably 1 to 10 denier, as in the case of the composite fiber. The fiber length of the synthetic fiber is preferably about 20 to 150 mm, as in the case of the composite fiber.

The mass ratio of the composite fiber to the synthetic fiber (composite fiber: synthetic fiber) is preferably 10:90 to 100: 0, and more preferably 30:70 to 80:20.

<Manufacturing method of pad body 30>
Next, one manufacturing method of the pad body 30 will be illustrated. However, the manufacturing method described below is an example, and other manufacturing methods may be used. The constituent fibers of the fiber body are a combination of composite fibers and synthetic fibers. However, only the composite fiber may be used, or the composite fiber and other fibers other than the synthetic fiber may be used in combination.

FIGS. 3 to 5 show a schematic diagram of an example of the manufacturing method. First, the composite fiber and the synthetic fiber are defibrated, respectively. The composite fiber and the synthetic fiber are weighed so as to have a predetermined ratio. The composite fiber and the synthetic fiber are mixed so as to have a uniform composition. When mixing the composite fiber and the synthetic fiber, the composite fiber and the synthetic fiber are arranged along the length direction of the fiber. A fiber sheet 40 having a predetermined thickness is formed from the composite fiber and the synthetic fiber.

Then, as shown in FIG. 3A, a large number of fiber sheets 40 are laminated. The thickness of the fiber sheet 40 is exaggerated. When laminating a large number of fiber sheets 40, the directions of the fibers of the fiber sheets 40 are aligned in one direction. The direction of the fibers is simply referred to as the fiber direction and is indicated by an arrow X. The direction orthogonal to the fiber direction in the plane of the fiber sheet 40 is referred to as a fiber orthogonal direction and is indicated by an arrow Y. The stacking direction of the fiber sheet 40 is indicated by an arrow Z.

Next, a large number of laminated fiber sheets 40 are sandwiched in the stacking direction by, for example, two flat plate-shaped pressing bodies facing each other in the stacking direction. The fiber sheet 40 is pressed by the two pressing bodies to obtain a predetermined thickness, and the fiber sheet 40 is further heated in the pressed state. This heating melts the low-temperature molten resin of the composite fiber. When the low-temperature molten resin is melted, the contact portions between the fibers are fused and integrated by the low-temperature molten resin, and a laminated body 41 made of fibers having a three-dimensional three-dimensional structure is formed as shown in FIG. 3 (b). .. By melting the low-temperature molten resin of the composite fiber, the composite fibers are fused to each other, and the composite fiber and the synthetic fiber are fused. In FIG. 3B, dots are attached to the contact portion 41a in which the fibers are fused to each other. The temperature at which the fiber sheet 40 is heated is equal to or higher than the melting temperature of the low-temperature molten resin of the composite fiber and lower than the melting temperature of the high-temperature molten resin of the composite fiber and the melting temperature of the synthetic fiber. By such a pressing and heating step, a large number of fiber sheets 40 are integrated. Instead of the method of pressing with two pressing bodies, for example, the fiber sheet 40 may be placed in a molding die and compressed and heated. In addition, in FIG. 3B and FIG. 4, the overlapping portion between the fiber sheets 40 is shown by a two-dot chain line instead of a solid line.

Next, as shown in FIG. 4, the laminated body 41 is cut to a predetermined thickness along the laminating direction and the fiber orthogonal direction to form a plate-shaped fibrous body 42. The cut surface of the plate-shaped fiber body 42 is the upper surface and the lower surface of the plate-shaped fiber body 42. That is, the cut surface becomes the plate surface of the plate-shaped fiber body 42. The thickness direction of the plate-shaped fiber body 42 is the fiber direction in the laminated body 41. The plate-shaped fiber body 42 has a large repulsive force against a force in the thickness direction, is excellent in cushioning property, and is hard to settle. Then, as shown in FIG. 5, the pad body 30 is formed by cutting the plate-shaped fiber body 42 into a predetermined shape.

<Mesh cover 31>
The mesh cover 31 is made of a mesh sheet such as knitting, woven fabric, or net. The mesh sheet may have elasticity or may not have elasticity. It is preferable that the mesh sheet has elasticity because the followability of the mesh cover 31 to the deformation of the pad body 30 becomes even better. The mesh sheet may have a pattern. For example, the mesh sheet may be imparted with antibacterial properties. The material of the mesh sheet is preferably a resin such as polyester, but it may be a natural material. In the case of a net, the intersection where the threads intersect may be in a state of only contact, a state of being fused, or a state of the threads being wound around each other. Good. It may be a resin net formed in a mesh shape by molding. The thickness of the threads constituting the mesh sheet is, for example, 0.01 to 0.5 mm. In the case of knitting, the thickness of the yarn is, for example, 0.01 to 0.1 mm, preferably 0.02 to 0.07 mm. In the case of a woven fabric, the thickness of the thread is, for example, 0.01 to 0.1 mm, preferably 0.02 to 0.07 mm. In the case of a net, the thickness of the thread is, for example, 0.01 to 0.3 mm, preferably 0.02 to 0.25 mm.

The mesh size of the mesh sheet is, for example, 0.01 to 2 mm. In the case of knitting, the mesh size is, for example, 0.01 to 1.5 mm, preferably 0.02 to 0.8 mm, and more preferably 0.03 to 0.5 mm. In the case of a woven fabric, the mesh size is, for example, 0.01 to 1.5 mm, preferably 0.02 to 0.8 mm, and more preferably 0.03 to 0.5 mm. In the case of a net, the mesh size is, for example, 0.01 to 1.5 mm, preferably 0.02 to 0.8 mm, and more preferably 0.03 to 0.5 mm.

The mesh cover 31 wraps the pad body 30. The mesh cover 31 wraps the entire or part of the pad body 30. At least the entire upper surface 30a of the pad body 30 is covered with the mesh cover 31. Preferably, the entire upper surface 30a and the entire side surface 30b of the pad body 30 are covered with the mesh cover 31. More preferably, the entire upper surface 30a of the pad body 30, the entire side surface 30b, and at least the peripheral edge of the lower surface 30c are covered with the mesh cover 31. It is also preferable that the entire pad body 30 is covered with the mesh cover 31. That is, it is also preferable that the entire upper surface 30a, the entire side surface 30b, and the entire lower surface 30c of the pad body 30 are covered with the mesh cover 31. It is preferable that the mesh cover 31 is not adhered or fused to the upper surface 30a and the side surface 30b of the pad body 30.

FIG. 6 shows a typical example of the configuration in which the pad body 30 is wrapped by the mesh cover 31. FIG. 6A shows a configuration in which the pad body 30 is partially wrapped by the mesh cover 31. Specifically, the mesh cover 31 covers the entire upper surface 30a and the entire side surface 30b of the pad body 30, and covers only the peripheral edge of the lower surface 30c of the pad body 30. The central portion of the lower surface 30c of the pad body 30 is exposed without being covered by the mesh cover 31. The mesh cover 31 is formed in a bag shape from a single mesh sheet. The pad body 30 is inserted into the bag-shaped mesh cover 31, and the opening of the bag-shaped mesh cover 31 is positioned on the lower surface 30c of the pad body 30. The width of the mesh cover 31 covering the peripheral edge of the lower surface 30c of the pad body 30 in an annular shape is, for example, 3 mm or more. A thread 32 is inserted through the mesh of the inner edge (opening edge) of the mesh cover 31 that covers the peripheral edge of the lower surface 30c of the pad body 30, and the opening edge of the mesh cover 31 is narrowed to reduce the diameter of the opening. Is preferable. With this configuration, peeling and misalignment of the mesh cover 31 are prevented. The mesh cover 31 is not adhered or fused to the pad body 30.

In FIG. 6B, similarly to FIG. 6A, the mesh cover 31 covers the entire upper surface 30a and the entire side surface 30b of the pad body 30, and also covers only the peripheral edge of the lower surface 30c of the pad body 30. Shows the configuration. The portion of the mesh cover 31 that covers the peripheral edge of the lower surface 30c of the pad body 30 is adhered or fused to the lower surface 30c of the pad body 30. In FIG. 6B, the portion of the mesh cover 31 that is not adhered or welded to the pad body 30 is indicated by a broken line, and the portion 31a that is adhered or welded to the pad body 30 is indicated by a solid line. In this configuration, the upper surface 30a and the side surface 30b of the pad body 30 are non-adhesive or non-welded to the mesh cover 31. This configuration also prevents the mesh cover 31 from being peeled off or misaligned.

FIG. 6C shows a configuration in which the entire pad body 30 is wrapped by the mesh cover 31. The mesh cover 31 is formed of two upper and lower mesh sheets. The peripheral edges of the two mesh sheets are joined and integrated. The joint is indicated by reference numeral 31b. Examples of the method of joining and integrating the peripheral portions of the two mesh sheets include welding, sewing, and the like, as well as welding by ultrasonic waves, high frequency, heat press, and the like. The joint portion 31b between the peripheral edges of the two mesh sheets is located outside the side surface 30b of the pad body 30, and circulates outside the side surface 30b.

FIG. 7 shows an outline of an example of a manufacturing method when the pad body 30 is wrapped with two upper and lower mesh sheets. First, as shown in FIG. 7A, the two mesh sheets 50 are arranged vertically separated from each other. The two mesh sheets 50 may be long or cut to a predetermined size. The pad body 30 is arranged between the two mesh sheets 50. Then, as shown in FIG. 7B, the two mesh sheets 50 are brought close to each other, and the pad body 30 is sandwiched vertically by the two mesh sheets 50. The pad body 30 is compressed and deformed by being pressed up and down by two mesh sheets 50. The two mesh sheets 50 are fused around the pad body 30. After fusing, the pad body 30 is restored to its original state. When the pad body 30 is restored to its original state, the upper surface 30a of the pad body 30 pushes the upper mesh sheet 50 upward, and the lower surface 30c of the pad body 30 pushes the lower mesh sheet 50 downward. Due to the elastic restoring force of the pad body 30, the upper surface 30a and the lower surface 30c of the pad body 30 are brought into close contact with the mesh cover 31. The peripheral edges of the two upper and lower mesh sheets may be integrated with each other by adhesion instead of welding. That is, the joint portion 31b may be a welded portion or an adhesive portion. Similarly, the pad body 30 may be wrapped with the mesh sheet by sewing the upper and lower mesh sheets 50 with a sewing machine or the like.

8 and 9 schematically show a perspective sectional view of the vicinity of the upper surface of the pad 2. FIG. 8 shows the case where the mesh cover 31 is a woven fabric. FIG. 9 shows the case where the mesh cover 31 is knitted. On the upper surface 30a of the pad body 30, many ends of fibers 43 constituting the fiber body are present. The end of the fiber 43 is entwined with the mesh cover 31. The ends of the fibers 43 are randomly bent. The end of the bent fiber 43 passes through the mesh of the mesh cover 31 and is entwined with the thread of the mesh cover 31 like a hook-and-loop fastener. In this way, the end portion of the fiber 43 is entangled with the mesh cover 31, so that the mesh cover 31 is locked to the upper surface 30a of the pad body 30. The mesh cover 31 is in close contact with the upper surface 30a of the pad body 30 due to the locking force of the ends of the fibers 43 on the upper surface 30a of the pad body 30.

As described above, the pad body 30 is wrapped by the mesh cover 31, and at least the entire upper surface 30a of the pad body 30 is covered by the mesh cover 31. The liquid cosmetic impregnated in the pad body 30 is transferred to the puff via the mesh cover 31. Therefore, it is possible to prevent the liquid cosmetics from being excessively taken out from the pad body 30. Especially, the effect is great at the initial stage of use. Since the mesh cover 31 is not fixed to the inner container 4, the degree of freedom of the mesh cover 31 is high. The mesh cover 31 can easily follow the deformation of the pad body 30. The mesh cover 31 is integrally deformed with the pad body 30. Therefore, it is possible to reduce the amount of leftover liquid cosmetics impregnated in the pad body 30. In addition, the discharge amount and the take-out amount of the liquid cosmetic can be adjusted over a long period of time.

Cushioned fibers are less likely to leave liquid cosmetics than sponges. The mesh cover 31 is not adhered or welded to the upper surface 30a of the pad body 30. Therefore, the mesh of the mesh cover 31 is not blocked, and the liquid cosmetic can easily pass through the mesh of the mesh cover 31 from the pad body 30. Further, the fibers on the upper surface 30a of the pad body 30 are also maintained in their original state. Therefore, the liquid cosmetic is smoothly transferred from the upper surface 30a of the pad body 30 to the puff via the mesh cover 31.

The end of the fiber 43 on the upper surface 30a of the pad body 30 is entwined with the mesh cover 31, and the mesh cover 31 is locked to the upper surface 30a of the pad body 30. Therefore, the mesh cover 31 is difficult to lift from the upper surface 30a of the pad body 30, and the mesh cover 31 can easily follow the deformation of the upper surface 30a of the pad body 30. The mesh cover 31 is difficult to separate from the upper surface 30a of the pad body 30, and the upper surface 30a of the pad body 30 and the mesh cover 31 are integrally deformed and restored to the original state. Therefore, the liquid cosmetics adhere to the puff evenly, and the liquid cosmetics are less left behind. Further, since the mesh cover 31 is in close contact with the upper surface 30a of the pad body 30, the aesthetics of the upper surface of the pad 2 is excellent. Even when the amount of liquid cosmetics is reduced, the mesh cover 31 maintains the aesthetic appearance of the upper surface of the pad 2.

FIG. 10A schematically shows a state in which the pad 2 is housed in the inner container body 10. As shown in FIG. 10B, when the pad 2 is pushed downward with a puff (not shown), the pad 2 is deformed. Since the mesh cover 31 is not fixed to the inner container body 10, the degree of freedom of the mesh cover 31 is large. Therefore, the mesh cover 31 can be easily deformed integrally with the pad body 30. As shown in FIG. 10C, it is also easy to push the peripheral edge of the pad 2 with the puff. The liquid cosmetic that tends to remain on the peripheral edge of the pad 2 can be easily taken out.

Hereinafter, an example and a comparative example will be given for further explanation.

[Example 1]
<Pad body 30>
The constituent fibers of the fiber body are a mixture of composite fibers and synthetic fibers. The composite fiber is a core-sheath type. The core component (high temperature molten resin) is polyethylene terephthalate. The sheath component (low temperature molten resin) is thermoplastic polyethylene terephthalate. The fineness of the composite fiber is 6 denier. The synthetic fiber is a polyethylene terephthalate fiber. The fineness of synthetic fibers is 3 denier. The mass ratio of the composite fiber to the synthetic fiber is 70:30. As shown in FIGS. 3 to 5, the fiber sheet 40 was formed by blending the composite fiber and the synthetic fiber so as to be parallel to each other. A large number of the fiber sheets 40 were laminated and pressed in the laminating direction and heated to melt the sheath component of the composite fiber to prepare a laminated body 41. The laminated body 41 was cut to a predetermined thickness to form a plate-shaped fibrous body 42. The plate-shaped fiber body 42 was cut to form a pad body 30 having a diameter of about 5 cm and a thickness of about 1 cm. The density of the pad body 30 is 18.0 kg / m ³ .

<Mesh cover 31>
For the mesh sheet, a tricot fabric made of 20 denier nylon yarn was used. The densities of the warp and weft of the tricot fabric are 35 threads / inch and 43 threads / inch, respectively. This tricot fabric was cut to a size of φ74 mm, and the peripheral edge portion was sewn with an elastic thread to prepare a bag-shaped mesh cover 31 having a stretchable opening.

<Pad 2>
The opening of the mesh cover 31 is widened to cover the pad body 30 with the mesh cover 31 so as not to cover the lower surface 30c of the pad body 30 but to cover only the entire upper surface 30a and the entire side surface 30b of the pad body 30. 2 was prepared.

<Cosmetics 1>
The pad 2 was impregnated with 15 g of a liquid cosmetic having a viscosity of 2000 mP · s and contained in an inner container 4 as shown in FIG. 1 to prepare a sample A of the cosmetic product 1.

[Example 2]
The pad body 30 is the same as in the first embodiment. The same tricot fabric as in Example 1 was used for the mesh sheet. The size of the tricot fabric was φ80 mm. The pad 2 was produced by covering the peripheral edge of the lower surface 30c of the pad body 30 with a bag-shaped mesh cover 31 in an annular shape having a width of 3 mm. Sample B of cosmetics 1 was prepared using the pad 2. The liquid cosmetic and the container are the same as in Example 1.

The pad 2 was produced by covering the entire lower surface 30c of the pad body 30 with a bag-shaped mesh cover 31. Sample D of cosmetics 1 was prepared using the pad 2. The liquid cosmetic and the container are the same as in Example 1.

[Example 5]
The pad body 30 is the same as in the first embodiment. The same tricot fabric as in Example 1 was used for the mesh sheet. Two mesh sheets were placed above and below the pad body 30, and the upper and lower mesh sheets were welded and fused by ultrasonic waves. A pad 2 in which the entire pad body 30 was covered with a mesh cover 31 was produced. Sample E of cosmetics 1 was prepared using the pad 2. The liquid cosmetic and the container are the same as in Example 1.

[Examples 6 to 8]
The pad body 30 is the same as in the first embodiment. For the mesh sheet, a tricot fabric made of 40 denier nylon yarn was used. The densities of the warp and weft of the tricot fabric are 33 threads / inch and 36 threads / inch, respectively. Samples F to H of cosmetics 1 in Examples 6 to 8 were prepared by the same production method as samples B to D of cosmetics 1 of Examples 2 to 4, respectively.

[Examples 9 to 12]
The pad body 30 differs only in density from that of the first embodiment. The density of the pad body 30 in Examples 9 to 12 is 24.0 kg / m ³ . Samples I to L of cosmetics 1 in Examples 9 to 12, respectively, were prepared by the same production method as samples B to E of cosmetics 1 of Examples 2 to 5.

[Examples 13 to 15]
The pad body 30 is the same as that of Examples 9 to 12. For the mesh sheet, the same tricot fabric as in Examples 6 to 8 was used. Samples M to O of cosmetics 1 in Examples 13 to 15, respectively, were prepared by the same production method as the samples F to H of cosmetics 1 of Examples 6 to 8.

[Comparative Example 1]
The pad 2 used was the same as the pad body 30 of Example 1 and was put in the inner container 4 as it was without being wrapped with the mesh cover 31. The same mesh sheet as in Examples 6 to 8 was ultrasonically welded to the upper surface of the retaining ring 12 to prepare sample P of cosmetics 1.

[Comparative Example 2]
A polyurethane foam (manufactured by Kurabo Industries, trade name: 301WH) was used for the pad 2. The size of the pad 2 is the same as that of the first embodiment. Similar to Comparative Example 1, the inner container 4 was used as it was without being covered with the mesh cover 31. Similar to Comparative Example 1, the same mesh sheet as in Examples 6 to 8 was ultrasonically welded to the upper surface of the retaining ring 12 to obtain sample Q of cosmetics 1.

[Test and evaluation]
For each sample, a liquid cosmetic take-out test and a residual rate of the liquid cosmetic were tested and evaluated. The liquid cosmetics take-out test examines the amount of liquid cosmetics taken and the uniformity thereof. In the take-out test, the upper surface of the pad 2 is tapped with a puff through the opening 13 of the inner container 4 to attach the liquid cosmetic of the pad 2 to the application surface of the puff. Then, the coated surface of the puff is pressed against the separately prepared paper to transfer the liquid cosmetics from the coated surface of the puff to the paper. Examine the amount and uniformity of liquid cosmetics adhering to the paper. The amount of adhesion can be measured by comparing the weight of the paper before adhesion with the weight of the paper after adhesion.

[Evaluation of adjustment of the amount taken]
The degree of adjustment of the amount taken was evaluated on a three-point scale of "○", "△", and "×" according to the following criteria.
〇: The amount of cosmetics removed is uniform. Specifically, when the above-mentioned puff operation is repeated 1 to 30 times, 31 to 60 times, 61 to 90 times, or 91 to 120 times, the amount of cosmetics collected on the paper is reduced. , 2.0 g or more and 4.0 g or less (appropriate amount).
Δ: The amount of cosmetics removed is almost uniform. Specifically, when the above-mentioned puff operation is repeated 1 to 30 times, 31 to 60 times, 61 to 90 times, or 91 to 120 times, the amount of cosmetics collected on the paper is reduced. , 1.0 g or more and less than 2.0 g (slightly less), or more than 4.0 g and 6.0 g or less (slightly more).
X: The amount of cosmetics removed is uneven. Specifically, when the above-mentioned puff operation is repeated 1 to 30 times, 31 to 60 times, 61 to 90 times, or 91 to 120 times, the amount of cosmetics collected on the paper is reduced. , Less than 1.0 g (less) or more than 6.0 g (more).

[Evaluation of survival rate]
The amount of cosmetics remaining on the pad 2 was evaluated by the residual rate. The survival rate was evaluated on a four-point scale from A to D as follows. Evaluation A was when the residual rate was 5% or more and less than 10%. The case where the residual rate was 10% or more and less than 15% was evaluated as evaluation B. The case where the residual rate was 15% or more and less than 20% was evaluated as C. The case where the residual rate was 20% or more was evaluated as evaluation D. Table 1 shows the evaluation results of Examples and Comparative Examples.

As shown in Table 1, in Examples 1 to 15, the degree of adjustment of the amount of cosmetics removed was a good result. Among them, in Examples 2 to 15, the degree of adjustment of the amount of cosmetics removed was particularly good. In addition, Examples 1 to 15 had a low residual rate and were good results. Among them, in Examples 2 to 15, the residual rate was particularly low. The reason why the adjustment of the amount taken and the residual rate differed between the first embodiment and the second to fifteenth embodiments is that only the pad 2 of the first embodiment has the lower surface 30c of the pad body 30 not covered by the mesh cover 31. It is thought that this is the reason. On the other hand, in Comparative Example 1, although the amount of cosmetics removed was almost uniform, the residual rate was high. In Comparative Example 2, the amount of cosmetics removed was uneven, and the residual rate was also very high.

Although the container having a double structure having the outer container 3 and the inner container 4 has been described, the container may not have the outer container 3. Further, the exterior body is not limited to the container, and may be a packaging bag.
