Japanese Patent No. 5465357

An object of the present invention is to equalize the amount of liquid cosmetics that can be collected.

A cosmetic product according to the present invention includes a pad and an adjustment sheet. The pad is impregnated with a liquid cosmetic. The adjustment sheet is superimposed on the pad. The adjusting sheet is for adjusting the amount of liquid cosmetic applied to the applicator. The adjustment sheet has an express section and a delay section. The liquid cosmetic is less likely to reach the upper surface of the delay section than the express delivery section. When the liquid cosmetic adheres to the applicator, the liquid cosmetic transfers from the pad to the adjustment sheet.

According to this configuration, the adjustment sheet is superimposed on the pad. The pad is impregnated with the liquid cosmetic, but the adjustment sheet is not impregnated with the liquid cosmetic. In use, the user presses an applicator such as a puff against the upper surface of the adjustment sheet. The pressing force of the applicator transfers the liquid cosmetic from the pad to the adjustment sheet. The liquid cosmetic easily reaches the upper surface of the express delivery section. On the other hand, it is difficult for the liquid cosmetic to reach the upper surface of the delay section. Therefore, in the initial stage of use, the liquid cosmetic is less likely to adhere to the applicator from the delay section, and the liquid cosmetic adheres to the applicator mainly from the express delivery section. Then, when the applicator is pressed against the adjustment sheet a certain number of times, the liquid cosmetic reaches the upper surface of the delay portion. As described above, in the initial stage of use, the liquid cosmetic hardly reaches the upper surface of the delay portion, and therefore the liquid cosmetic is mainly discharged from the upper surface of the express delivery portion and adheres to the applicator. As a result, the amount of the liquid cosmetic that adheres to the applicator at the initial stage of use is suppressed. On the other hand, when the applicator is pressed against the adjustment sheet multiple times, the liquid cosmetic is discharged from both the upper surface of the express delivery section and the upper surface of the delay section and adheres to the applicator. Even after the start of use, liquid cosmetics continue to be supplied to the adjusting sheet from the pad. The supplied liquid cosmetic easily reaches the upper surface of the express delivery section, but hardly reaches the upper surface of the delay section. Therefore, even after the start of use, a large amount of the liquid cosmetic is taken out from the upper surface of the express delivery portion and a small amount is taken out from the upper surface of the delay portion.

Preferably, the adjustment sheet has a large number of thick-walled portions and thin-walled portions. The thin portion is the express delivery portion and the thick portion is the delay portion. According to this configuration, the liquid cosmetic of the pad moves to the thin portion and easily reaches the upper surface of the thin portion. On the other hand, the liquid cosmetic of the pad also migrates to the thick portion. However, the liquid cosmetic does not immediately reach the upper surface of the thick portion. By pressing the applicator against the adjusting sheet a plurality of times, the liquid cosmetic gradually penetrates into the thick portion. Then, the liquid cosmetic eventually permeates and reaches the upper surface of the thick portion. The thick portion functions as a tank for storing the liquid cosmetic or as a buffer, and the thick portion delays the liquid cosmetic from reaching the upper surface of the adjustment sheet. In this way, the thick portion limits the amount of liquid cosmetic that can be taken.

Preferably, a large number of projections are provided on the upper surface of the adjustment sheet. The thicker portions correspond to the protrusions, and the thinner portions correspond to between the protrusions. According to this configuration, in the initial stage of use, the liquid cosmetic is taken out from the thin portion located between the convex portions. Therefore, it is possible to prevent an excessive amount of the liquid cosmetic from being taken out at the initial stage of use. In addition, the amount of the liquid cosmetic that can be collected can be easily controlled by changing the shape, size, arrangement, etc. of the projections.

Preferably, the projection has a tapered shape that gradually tapers upward. According to this configuration, the applicator can easily enter between the protrusions at the initial stage of use. Therefore, the liquid cosmetic easily adheres to the applicator from the thin portion.

Preferably, the conditioning sheet is made of air-laid nonwoven fabric. With this configuration, it is easy to make the density of the fibers in the thick portion and the density of the fibers in the thin portion substantially constant. In addition, the thick portion and the thin portion of the adjustment sheet can be easily formed in a substantially constant density state. Therefore, the removal amount can be easily controlled by the difference in thickness between the thick portion and the thin portion.

Further, the method for producing a cosmetic according to the present invention includes the steps of: impregnating a pad with a liquid cosmetic; placing an adjustment sheet not impregnated with the liquid cosmetic on the pad impregnated with the liquid cosmetic; including.

Also, the adjustment sheet for cosmetics according to the present invention is superimposed on the pad. The pad is impregnated with a liquid cosmetic. The adjusting sheet is for adjusting the amount of liquid cosmetic applied to the applicator. The adjustment sheet has an express section and a delay section. The liquid cosmetic is less likely to reach the upper surface of the delay section than the express delivery section.

As described above, the adjustment sheet is superimposed on the pad impregnated with the liquid cosmetic, and the adjustment sheet has the rapid delivery portion and the delay portion, so that an excessive amount of the liquid cosmetic does not reach the applicator at the beginning of use. Adhesion is suppressed, and the amount of the liquid cosmetic that can be taken is leveled.

<Liquid cosmetics>
Liquid cosmetics are, for example, liquid foundations, blushes, serums, milky lotions, and the like.

<Pad 2>
The pad 2 is impregnated with a liquid cosmetic. Pad 2 is soft. Pad 2 can be easily deformed. The shape of the pad 2 corresponds to the shape of the accommodating portion of the inner container main body 10 . In this embodiment, the pad 2 has a circular shape in plan view. However, the pad 2 may have a rectangular shape or the like in plan view. As shown in FIG. 2(b), the pad 2 has a columnar shape whose dimension (thickness) in the direction of the center line is smaller than its diameter. The diameter of the pad 2 is, for example, approximately 3 to 15 cm. The thickness of the pad 2 is, for example, approximately 0.5 to 5 cm.

The pad 2 may be made of any material as long as it can be impregnated with the liquid cosmetic. The material of the pad 2 may be various urethane foams, but is preferably fibrous. The fibrous body has cushioning properties. A fibrous body is a structure in which fibers intersect three-dimensionally like a jungle gym. A fibrous body is a three-dimensional structure. A crossing portion where fibers cross each other is a contact portion where fibers are in contact with each other. The fibers are fused together at the contact portion. The density of the fibrous body is, for example, about 6-50 kg/m ³ , preferably about 6-30 kg/m ³ . The Asker F hardness of the fibrous body is preferably about 30-60. The Asker F hardness is a value measured at a temperature of 25° C. using an Asker rubber hardness tester F type manufactured by Kobunshi Keiki Co., Ltd. Incidentally, the pad 2 may be of a single layer or of multiple layers.

Various types of fibers may be used to form the fibrous body, but it is preferable to include composite fibers. Composite fibers contain two resins with different melting temperatures. The fibers are fused together at the contact portions by melting the resin having the lower melting temperature among the two types of resins. The resin with the higher melting temperature is called the high-melting resin, and the resin with the lower melting temperature is called the low-melting resin.

The conjugate fiber is, for example, a core-sheath type conjugate fiber, a side-by-side type conjugate fiber, a sea-island type conjugate fiber, or the like. A core-sheath type conjugate fiber is preferable from the viewpoint of efficiently integrating the contact portions of the fibers. Side-by-side type conjugate fibers are preferred when the fibers are crimped by heating.

A core-sheath type conjugate fiber includes a core component as a central component and a sheath component covering the core component. A high temperature melting resin is used for the core component. A low-temperature melting resin is used for the sheath component. The conjugate fibers are firmly integrated with each other by the low-temperature melting resin at the contact portion between the fibers. The volume ratio of the core component to the sheath component (core component:sheath component) is preferably 30:70 to 70:30.

Low-temperature melting resins include, for example, polyesters and thermoplastic elastomers. Specific examples of polyesters include polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polyhexamethylene terephthalate, and polytetramethylene terephthalate. Examples of thermoplastic elastomers include polyester-based elastomers such as polyethylene terephthalate-based elastomers, and polyether-ester block copolymers having polyester as a hard segment and poly(alkylene oxide) glycol as a soft segment.

High-temperature melting resins include, for example, thermoplastic polyesters. Examples of thermoplastic polyesters include polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polyhexamethylene terephthalate, and polytetramethylene terephthalate.

The fineness of the composite fiber is preferably 0.5 to 15 denier, more preferably 1 to 10 denier. When the fineness is within this range, the liquid cosmetic taken into the pad 2 can be efficiently taken out to the outside. Also, a pad 2 having excellent mechanical strength can be obtained. The fiber fineness is the mass (g) of the fiber (filament) per 9000 m of fiber length.

The fiber length of the conjugate fiber is preferably about 20 to 150 mm. When the fiber length is within this range, the liquid cosmetic taken into the pad 2 can be efficiently taken out, and the pad 2 having excellent mechanical strength can be obtained. If necessary, the conjugate fiber may be subjected to an antibacterial treatment, an antibacterial treatment, or the like.

The fibrous body contains composite fibers as constituent fibers. The fibrous body may be composed only of conjugated fibers, or may be composed of conjugated fibers and fibers other than conjugated fibers. Examples of other fibers include natural fibers such as cotton, linen, and silk, regenerated fibers such as rayon, and synthetic fibers, with synthetic fibers being particularly preferred. It is preferable that the conjugate fiber and the synthetic fiber are fused at their mutual contact portions.

Examples of synthetic fibers include polyester fibers such as polyethylene terephthalate fiber, polybutylene terephthalate fiber, polytrimethylene terephthalate fiber, polyvinyl chloride fiber, polyvinylidene chloride fiber, polypropylene fiber, polyvinyl alcohol fiber, nylon 6, and the like. Examples thereof include polyamide fibers, polyimide fibers, polyamideimide fibers, cellulose acetate fibers, etc., but the present invention is not limited to these examples. Each of these fibers may be used alone, or two or more of them may be used in combination. Among these synthetic fibers, polyester fibers and polyamide fibers are preferred, and polyester fibers are more preferred. Synthetic fibers may be processed, for example, antibacterial or antibacterial, if necessary.

The melting temperature of the synthetic fiber is preferably 20° C. or higher, more preferably 30° C. or higher, than the melting temperature of the low-melting resin of the conjugate fiber, from the viewpoint of preventing sag of the conjugate fiber and a decrease in elastic force. . The melting temperature of the synthetic fiber is preferably 150 to 270° C. from the viewpoint of preventing sag of the conjugate fiber and efficiently heat-sealing the conjugate fiber and the synthetic fiber at the contact portion between the conjugate 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, like the composite fiber. The fiber length of the synthetic fiber is preferably about 20 to 150 mm, like the composite fiber.

It is preferable that the composite fiber and the synthetic fiber are used in combination as another fiber. More preferably, polyester fibers or polyamide fibers are used in combination as composite fibers and synthetic fibers. It is more preferable that the conjugate fiber and the polyester fiber are used together. The mass ratio of the conjugate fiber to the synthetic fiber (conjugate fiber:synthetic fiber) is preferably 10:90 to 100:0, more preferably 30:70 to 80:20.

<Manufacturing method of pad 2>
Next, one manufacturing method of the pad 2 is illustrated. However, the manufacturing method described below is an example, and other manufacturing methods may be used. Constituent fibers of the fibrous body are a combination of composite fibers and synthetic fibers. However, the composite fiber may be used alone, or the composite fiber and other fibers other than the synthetic fiber may be used together.

4 to 6 schematically show an example of the manufacturing method. First, conjugate fibers and synthetic fibers are defibrated. The conjugate fiber and the synthetic fiber are weighed so as to have a predetermined ratio. Composite fibers and synthetic fibers are mixed so as to have a uniform composition. When mixing the composite fibers and the synthetic fibers, the composite fibers and the synthetic fibers are arranged along the length direction of the fibers. Composite fibers and synthetic fibers form a fiber sheet 40 having a predetermined thickness.

A large number of fiber sheets 40 are laminated as shown in FIG. 4(a). Note that the thickness of the fiber sheet 40 is exaggerated. When laminating a large number of fiber sheets 40, the fibers of the fiber sheets 40 are made to align in one direction. The direction of the fibers is simply referred to as the fiber direction and is indicated by the arrow X. The direction orthogonal to the fiber direction in the plane of the fiber sheet 40 is called the fiber orthogonal direction and indicated by an arrow Y. As shown in FIG. An arrow Z indicates the stacking direction of the fiber sheets 40 .

Next, a large number of laminated fiber sheets 40 are sandwiched in the lamination direction by, for example, two flat plate-like pressing members (not shown) facing each other in the lamination direction. The fiber sheet 40 is pressed by two pressing bodies to a predetermined thickness, and the fiber sheet 40 is heated while being pressed. This heating melts the low-temperature melting resin of the composite fiber. By melting the low-temperature melting resin, the contact portions of the fibers are fused and integrated by the low-temperature melting resin, and a laminate 41 composed of fibers having a three-dimensional three-dimensional structure is formed as shown in FIG. 4(b). . Due to the melting of the low-temperature melting resin of the conjugate fibers, the conjugate fibers are fused together and the conjugate fibers and the synthetic fibers are fused. In FIG. 4(b), the contact portions 41a where the fibers are fused together are indicated by dots. The temperature for heating the fiber sheet 40 is equal to or higher than the melting temperature of the low-temperature melting resin of the composite fibers and lower than the melting temperature of the high-temperature melting resin of the composite fibers and the melting temperature of the synthetic fibers. A large number of fiber sheets 40 are integrated by such a pressing and heating process. Instead of the method of pressing with two pressing bodies, for example, the fiber sheet 40 may be placed in a mold, compressed and heated. 4(b) and 5, overlapping portions of the fiber sheets 40 are indicated by two-dot chain lines instead of solid lines.

Next, as shown in FIG. 5, the laminated body 41 is cut to a predetermined thickness along the lamination direction and the fiber orthogonal direction to form a plate-like fiber body 42 . The cut surfaces of the plate-like fibrous body 42 are the upper and lower faces of the plate-like fibrous body 42 . That is, the cut surface becomes the plate surface of the plate-like fiber body 42 . The thickness direction of the plate-like fibrous body 42 is the fiber direction of the laminate 41 . The plate-shaped fibrous body 42 has a large repulsive force against a force in the thickness direction, is excellent in cushioning properties, and is resistant to fatigue. Then, as shown in FIG. 6, the pad 2 is formed by cutting the plate-like fiber body 42 into a predetermined shape.

<Adjustment sheet 5>
An adjustment sheet 5 is placed on the pad 2 for adjusting the amount of liquid cosmetic that can be taken. The adjustment sheet 5 is superimposed on the top surface of the pad 2 . The pad 2 is impregnated with the liquid cosmetic, but the adjustment sheet 5 is not impregnated with the liquid cosmetic. The shape and size of the adjustment sheet 5 correspond to the upper surface of the pad 2 . In this embodiment, as described above, the pad 2 has a cylindrical shape and the upper surface of the pad 2 has a circular shape. Therefore, the adjustment sheet 5 is circular. The adjustment sheet 5 covers the entire upper surface of the pad 2. - 特許庁A peripheral portion of the adjustment sheet 5 is held down by a retainer ring 12 from above. Therefore, the overlapping state of the pad 2 and the adjustment sheet 5 is maintained. The rest of the adjustment sheet 5 excluding the peripheral edge is not held down by the retainer ring 12 and is open and exposed through the opening 13 .

Various materials may be used for the adjustment sheet 5 . The adjustment sheet 5 is preferably made of nonwoven fabric, more preferably made of air-laid nonwoven fabric. Air-laid nonwoven fabrics contain thermally bondable fibers. The thermoadhesive fibers are thermally melted and bonded together. Bonding between fibers by melting results in a nonwoven fabric with a network structure. Thermoadhesive fibers are bicomponent fibers. The composite fibers are the same as those of the pad 2, and are preferably core-sheath type composite fibers or side-by-side type composite fibers.

A core-sheath type conjugate fiber includes a core component as a central component and a sheath component covering the core component. A high-temperature melting resin is used for the core component, and a low-temperature melting resin is used for the sheath component. High-temperature melting resins are, for example, thermoplastic polyesters such as polyethylene terephthalate. A low-temperature melting resin is, for example, a polyolefin such as polyethylene. At the contact portion between the fibers, the conjugate fibers are bonded together by the sheath component, which is a low-temperature melting resin. Composite fibers are staple fibers with a short fiber length. The fiber length of the conjugate fiber is, for example, 2-15 mm, preferably 3-5 mm. The fineness of the composite fiber is, for example, 0.2 to 60 dtex, preferably 0.8 to 35 dtex, more preferably 1.0 to 10 dtex. The air-laid nonwoven fabric contains 30 to 100% by weight, preferably 70 to 100% by weight, of bicomponent fibers. If necessary, the conjugate fiber may be subjected to an antibacterial treatment, an antibacterial treatment, or the like. The air-laid nonwoven fabric may contain fibers other than the heat-adhesive fibers. Other fibers may be synthetic fibers or natural fibers.

An air-laid nonwoven fabric is formed by depositing the conjugate fibers on a collection net (not shown) and heating at about 140° C. to heat-seal the fibers. When the air-laid nonwoven fabric is manufactured, unevenness is formed on one side of the air-laid nonwoven fabric. The trapping net is formed with irregularities, and irregularities are formed on one side of the air-laid nonwoven fabric corresponding to the irregularities of the trapping net.

The adjustment sheet 5 has an express delivery portion and a delay portion in which the liquid cosmetic is less likely to reach the upper surface 5a than in the express delivery portion. The configuration of the express delivery section and the delay section may vary. In this embodiment, a large number of projections 50 are formed on the upper surface 5a of the adjustment sheet 5. As shown in FIG. A lower surface 5b of the adjustment sheet 5 is substantially flat. The projections 50 are formed by the projections and depressions of the collection net as described above. The adjustment sheet 5 has a large number of thick portions 51 and thin portions 52 due to the large number of protrusions 50 formed on the upper surface 5 a of the adjustment sheet 5 . Thick portion 51 is thicker than thin portion 52 . The position of the convex portion 50 is the thick portion 51 , and the position between the adjacent convex portions 50 is the thin portion 52 . The thin portion 52 may have a constant thickness or may vary in thickness. The upper surface of the thick portion 51 is the top portion of the convex portion 50 . The convex portion 50 protrudes above the thin portion 52 . The protrusion height of the convex portion 50 is the dimension from the upper surface of the thin portion 52 to the top portion of the convex portion 50 . The thin portion 52 is the express delivery portion and the thick portion 51 is the delay portion.

The convex portion 50 may have various three-dimensional shapes. The convex portion 50 may have, for example, a prismatic shape, a cylindrical shape, or the like, but preferably has a tapered shape that gradually tapers upward. Specifically, the protrusion 50 has a pyramid shape such as a pyramid shape or a conical shape, a truncated pyramid shape such as a truncated pyramid shape or a truncated cone shape, a hemispherical shape, a dome shape, or the like. The planar shape of the projection 50 viewed from above is, for example, a polygon such as a rhombus, a circle, an ellipse, or the like. The size of the convex portion 50 in plan view is, for example, 1 to 20 mm. The size of the convex portion 50 in a plan view is the diameter of a circle, the major diameter of an ellipse, and the length of the longest diagonal of a polygon. The number and arrangement of the protrusions 50 are arbitrary. The protrusions 50 may be arranged in an array or may be arranged at random. A plurality of types of protrusions 50 having different shapes and protrusion heights may be arranged. The spacing between the protrusions 50 may be uniform or non-uniform.

The total thickness of the adjustment sheet 5 is, for example, 0.5-4 mm, preferably 1-3 mm. The total thickness of the adjusting sheet 5 is the thickness from the lower surface 5b of the adjusting sheet 5 to the upper surface 5a of the adjusting sheet 5. When the lower surface 5b of the adjusting sheet 5 is substantially flat, the adjusting sheet 5 is the dimension from the lower surface 5b of the to the top of the projection 50. FIG. The thickness ratio between the thin portion 52 and the thick portion 51 is, for example, 1:1.2 to 1:12.5, preferably 1:1.8 to 1:10. The surface area ratio of the thin portion 52 and the thick portion 51 is, for example, 1:1.5 to 1:10, preferably 1:1.6 to 1:5. The ratio of the projected areas of the thin portion 52 and the thick portion 51 in plan view is, for example, 1:0.3 to 1:3.5, preferably 1:0.7 to 1:3. The fiber density in the thick portion 51 and the fiber density in the thin portion 52 are substantially equal to each other. The ratio of the fiber density in the thin portion 52 to the fiber density in the thick portion 51 is, for example, 1:0.8 to 1:1.2, preferably 1:0.9 to 1:1.1. The weight ratio of the thin portion 52 to the thick portion 51 is, for example, 1:1.2 to 1:20, preferably 1:1.5 to 1:10.

FIG. 3 shows an example of the convex portion 50 of the adjustment sheet 5. As shown in FIG. The convex portion 50 has a quadrangular pyramidal shape that is a rhombus in plan view. 7 to 9 show other examples of the convex portion 50 of the adjustment sheet 5. FIG. As shown in FIG. 9, the convex portion 50 has an elliptical dome shape in plan view.

The step of impregnating the pad 2 with the liquid cosmetic may be performed before the pad 2 is accommodated in the inner container 20 or after the pad 2 is accommodated in the inner container 20 . However, before housing the pad 2 in the inner container 20, it is preferable to impregnate the pad 2 with the liquid cosmetic in advance. Alternatively, the adjustment sheet 5 may be placed on the pad 2 after the pad 2 is accommodated in the inner container 20, or the adjustment sheet 5 may be placed on the pad 2 before the pad 2 is accommodated in the inner container 20. may

As described above, the adjustment sheet 5 not impregnated with the liquid cosmetic is placed on the pad 2 impregnated with the liquid cosmetic. Since the adjustment sheet 5 is placed on the upper surface of the pad 2, the upper surface of the pad 2 has an excellent appearance. It is also possible to form various patterns with the projections 50 .

The adjustment sheet 5 is neither adhered nor welded to the upper surface of the pad 2 . Therefore, when the user presses the puff 6 against the upper surface 5 a of the adjustment sheet 5 , the liquid cosmetic impregnated in the pad 2 smoothly transfers to the adjustment sheet 5 . The liquid cosmetic easily reaches the upper surface of the thin portion 52 but hardly reaches the upper surface of the thick portion 51 . Therefore, in the initial stage, it is difficult for the liquid cosmetic to adhere to the puff 6 from the thick portion 51 , and the liquid cosmetic adheres to the puff 6 mainly from the thin portion 52 . Each time the puff 6 is repeatedly pressed against the adjusting sheet 5 , the liquid cosmetic gradually permeates the thick portion 51 and eventually reaches the upper surface of the thick portion 51 . Thus, the thick portion 51 delays the liquid cosmetic from reaching the upper surface 5 a of the adjusting sheet 5 .

At the initial stage, the liquid cosmetic is not taken from the thick portion 51 and is mainly taken from the thin portion 52 . That is, the thick portion 51 limits the amount of liquid cosmetic that can be taken. Therefore, excessive extraction of the liquid cosmetic in the initial stage is prevented.

Liquid cosmetics continue to be supplied from the pad 2 to the adjustment sheet 5 even after the start of use. The liquid cosmetic continuously supplied from the pad 2 to the adjustment sheet 5 easily reaches the upper surface of the thin portion 52 but hardly reaches the upper surface of the thick portion 51 . Therefore, even after the start of use, the amount of the liquid cosmetic that can be taken is limited, and the amount of the liquid cosmetic that can be taken can be made uniform. In addition, the removal amount can be easily controlled by the protrusion height, size, etc. of the convex portion 50 .

It should be noted that the liquid cosmetic does not easily remain in the fibrous body as compared with the sponge. Therefore, when the pad 2 is made of fibrous material, it is possible to reduce the amount of the liquid cosmetic that remains on the pad 2 without being removed.

Examples and comparative examples are given below for further explanation.

[Example 1]
<Pad 2>
The material of the pad 2 is a fibrous body. The constituent fibers of the fibrous body are a mixture of composite fibers and synthetic fibers. Composite fibers are of a sheath-core type. The core component (high temperature melting resin) is polyethylene terephthalate. The sheath component (low temperature melting resin) is thermoplastic polyethylene terephthalate. The composite fiber has a fineness of 6 denier. Synthetic fibers are polyethylene terephthalate fibers. The synthetic fiber has a fineness of 3 denier. The mass ratio of conjugate fibers and synthetic fibers is 70:30. As shown in FIGS. 4 to 6, a fiber sheet 40 is formed by blending conjugate fibers and synthetic fibers in parallel. A number of the fiber sheets 40 are laminated, pressed in the lamination direction and heated to produce a laminate 41 . This laminated body 41 is cut in the lamination direction and the fiber orthogonal direction to form a plate-like fiber body 42 having a predetermined thickness. A plate-like fiber body 42 is cut to form a pad 2 having a diameter of about 5 cm and a thickness of about 1 cm. Incidentally, the density of the pad 2 is 18.0 kg/m ³ . The basis weight of the pad 2 is 180 g/m ² . The pad 2 is impregnated with 15 g of a liquid cosmetic having a viscosity of 10000 mP·s and is housed in the inner container 4 .

<Adjustment sheet 5>
The adjustment sheet 5 is made of air-laid nonwoven fabric. The air-laid nonwoven fabric is obtained by stacking core-sheath type composite fibers having a fineness of 1.7 dtex and a fiber length of 3 mm, which have a polyethylene sheath and a polyethylene terephthalate core (PE/PET), on a net, and is heated at about 140 ° C. are heat-sealed.

The total thickness of the adjustment sheet 5 is 1.2 mm. The thickness of the thick portion 51 is 1.2 mm, the thickness of the thin portion 52 is 0.3 mm, and the projection height of the convex portion 50 is 0.9 mm. The shape of the convex portion 50 is the same as that of the second embodiment.

[Examples 4-6]
The pad 2 of Examples 1-3 was changed to one having a basis weight of 240 g/m ² , and other conditions were the same as those of Examples 1-3.

[Example 7]
The pad 2 is made of polyurethane foam (manufactured by Kurashiki Boseki, trade name: 301WH). The adjustment sheet 5 is the same as in the second embodiment.

[Comparative Example 1]
Pad 2 is the same as in Example 1. However, the adjustment sheet 5 is not placed on the pad 2, and only the pad 2 is used.

[Comparative Example 2]
Pad 2 is made of the same polyurethane foam as in Example 7. However, unlike the seventh embodiment, the upper surface of the pad 2 is thermally compressed over its entirety. As in Comparative Example 1, only the pad 2 is used without the adjustment sheet 5 placed thereon.

[Test and Evaluation]
A take-out test of the liquid cosmetics was conducted. The removal test of the liquid cosmetic is to examine the amount of the liquid cosmetic that can be removed. In the take-out test, the upper surface 5a of the adjustment sheet 5 or the upper surface of the pad 2 is hit with the puff 6 through the opening 13 of the inner container 4 to adhere the liquid cosmetic to the application surface of the puff 6. Then, the application surface of the puff 6 is pressed against separately prepared paper to transfer the liquid cosmetic from the application surface of the puff 6 to the paper. The operation of attaching the liquid cosmetic to the puff 6 and transferring it from the puff 6 to the paper is regarded as one operation, and this operation is repeated. Every time this operation is performed 30 times, the amount of the liquid cosmetic adhering to the paper is examined. That is, from 1 to 30 times, from 31 to 60 times, from 61 to 90 times, and from 91 to 120 times, the adhesion amount is measured every 30 times. The adhesion amount can be measured by comparing the weight of the paper before adhesion and the weight of the paper after adhesion. This adhered amount is taken as the removed amount. The uniformity of the obtained amount is evaluated by comparing the obtained amount every 30 times. In particular, in order to evaluate the initial performance in detail, the 1st to 30th cycles were further divided into three grades of 1 to 10 cycles, 11 to 20 cycles, and 21 to 30 cycles. Table 1 shows the evaluation results of Examples and Comparative Examples.

As shown in Table 1, in Examples 1 to 7, the amount obtained every 30 times is uniform. Furthermore, the yield is stable for the initial 1 to 30 times. On the other hand, in Comparative Examples 1 and 2 in which the adjustment sheet 5 was not placed, the removed amount was very large in the initial stage, and thereafter, the removed amount decreased rapidly. Among them, the amount obtained in the 1st to 10th times, which is the earliest stage, is large. FIG. 10 is a graph showing the amount obtained every 30 times for Example 1 and Comparative Example 1. As shown in FIG. Thus, in Example 1, the yield is stable and uniform. On the other hand, in Comparative Example 1, the initial yield was large, and then the yield decreased sharply.

Although the container has a double structure including the outer container 3 and the inner container 4, a container without the outer container 3 may be used. Also, an exterior body other than a container may be used, and the exterior body may be a packaging bag.
