Description

  The present invention relates to a chip for applying cosmetics.

Cosmetic chips are known as cosmetic tools used for applying powdery lame, eye shadow, and the like. During eye makeup, the eye shadow is applied to the entire upper and lower eyelids of the eye or to the double width using a tip, or the applied eye shadow is blurred using the tip, creating a gradation. .
There are several examples of the shape of the cosmetic chip used at this time.

For example, the chip described in Patent Document 1 has a substantially spindle-shaped coating portion formed of urethane or the like at the tip of a plate-like substrate having elasticity, and a spindle-shaped convex end portion is formed at the tip. It has become a shape.
The cosmetic chip described in Patent Document 2 is provided with a core material having elasticity around the shaft, an application part in which a skin is provided on the surface, and a massive application part at the other end. is there.
The cosmetic swab described in Patent Document 3 has a cotton ball attached to a base material and is biased so as to become flat toward the tip portion, and the tip portion forms an arc shape. It will be.
The cosmetic applicator described in Patent Document 4 is an applicator formed by inserting a plate-shaped applicator attachment portion into a bag-shaped applicator.
After applying eye shadow etc. to the application surface of such a cosmetic chip, make it by contacting it with the eyelid or double width part and applying or spreading eye shadow etc. Yes.

In such makeup, it is required to carefully apply fine parts such as eyelids and double widths. However, the cosmetic chips described in Patent Documents 1 to 4 are Since the application part is connected to a mounting member having a plate shape or the like, if the plate mounting member has rigidity, the cosmetic chip also has rigidity. Cosmetic tips were used using physical properties.
Further, when the mounting member has elasticity and the shape thereof is plate-shaped, when it is used as a cosmetic chip, it can exhibit sufficient elasticity particularly in a certain direction. Cosmetics were applied in consideration of the properties.

When making a fine part such as an eyelid or double width, it is required to carefully apply the fine part. However, the cosmetic chip as described in Patent Documents 1 to 4 is a cosmetic chip. Since the inside of the coating part is connected to a mounting member having a shape such as a plate having high rigidity, the entire cosmetic chip also has rigidity, and the cosmetic chip is used by utilizing such physical properties. Thus, it is difficult to apply the cosmetic material precisely while applying the cosmetic chip. Moreover, even if the plate-like attachment member has elasticity, when the shape is plate-like, the direction in which the elasticity can be sufficiently exerted is limited when the cosmetic chip is used. The flexibility in the width direction is inferior.
Then, when applying cosmetics with a cosmetic chip, it may be difficult to accurately apply cosmetics using the elasticity of the cosmetic chip because it cannot provide sufficient elasticity depending on the orientation of the chip. It has become.

As a result of intensive studies by the inventor in order to solve the above problems, it has been found that the above problems can be solved by employing the following means.
1. A cosmetic chip comprising a coating portion made of a porous member at the tip of an elastic base having a spindle shape and a circular cross section.
A cosmetic chip with a handle obtained by attaching the cosmetic chip according to 2.1 to a handle via a base.

The cosmetic chip of the present invention has a spindle shape, and the base material carrying the application part is made of an elastic base material. Therefore, the elasticity is applied to the cosmetic chip together with the application part provided on the surface. Thus, the cosmetic chip can be made omnidirectional.
For this reason, in applying makeup, when applying cosmetics by using the bending of the chip, the application part of the chip is smoothly brought into contact with the skin surface without considering the directionality of the chip. Can do.
By having such a structure, it is possible to surely apply as intended to places where fine application such as eyelids, double width, and eyes is required.
Furthermore, by attaching the chip to the handle via the base, the bending of the chip in all directions can be used more effectively, and makeup can be performed as intended.

(Structure of cosmetic chip of the present invention)
The cosmetic chip of the present invention is provided at one end of a support similar to a known cosmetic chip.
And it has the application part 1 of the cosmetics which consist of a porous member, and the application part 1 is provided in this front-end | tip of the spindle-shaped elastic base material 2 at the front-end | tip.
In order to make a cosmetic chip having the same degree of flexibility in an arbitrary direction, the present invention is particularly characterized in the form and physical properties of the elastic base material 2 carrying the cosmetic application portion. The cut surface in a direction perpendicular to the length direction is circular.

(Applying part)
The cosmetic chip of the present invention will be described below based on the drawings.
FIG. 1 is a view showing an application part 1, and the application part 1 is made of a known porous member made of synthetic resin such as polyurethane or polyolefin resin, natural resin, or a resin-planted resin member.
The porous member may have open cells or closed cells. When a cosmetic chip is formed, it constitutes the surface for carrying the cosmetic, and therefore it is necessary to have a porosity sufficient to carry the required amount of powder or liquid cosmetic.
Similarly, when it is made of a resin-made member planted, it is required to be planted to such an extent that cosmetics can be carried.
That is, it is desirable that the application part 1 of the cosmetic chip of the present invention is porous or flocked so that it can be impregnated with or supported by the cosmetic. The porosity in the case of being porous may be the same level as that of a normal cosmetic chip, and is appropriately determined according to the type of cosmetic used, the viscosity, the site to be used, the area and thickness of the coated surface, etc. From the viewpoint of usability such as the amount of impregnation and the amount of support, it is necessary to achieve porosity.
Even in the case where the coating unit 1 is a layer in which hair is planted, the density and hair length thereof can be studied and the amount of impregnation or loading of the target cosmetic can be obtained.
The structure of the applicator 1 itself is such that the porous member has a bag shape, and the tip of a resilient base having a spindle-shaped tip and a circular cross-section is inserted therein, thereby applying the applicator for the cosmetic chip. A surface can be formed.

Therefore, the size of the application part 1 also depends on the size of the elastic base material to be inserted, and the bag-like inner diameter and length are the application diameters to be formed on the outer diameter of the elastic base material and the tip of the cosmetic chip. It is determined by the length of the part. For this reason, the internal diameter of the application part 1 which has a bag shape is 1-35 mm, Preferably it is 3-20 mm, More preferably, it is 5-10 mm, The length of the application part 1 is 5-40 mm, Preferably it is 8-30 mm, More preferably, it is 10-20 mm.
Furthermore, the thickness of the porous member which forms this application part 1 is 0.2-3 mm, Preferably it is 1.0-2.5 mm, More preferably, it is 1.5-2.0 mm.

  Further, as a specific method for obtaining the porous member used in the application part 1, the open cell sponge is sliced with a slicing blade to have a thickness of 0.2 to 3 mm, more preferably 1 to 2.5 mm. Thus, a slice sheet having both sides sliced is obtained. The slicing is performed for the purpose of adjusting the amount of the cosmetic material or the like impregnated during use by removing the dense layer existing on the sponge surface, that is, the skin layer, and adjusting the thickness. It is difficult to make the thickness of the slice sheet less than 0.2 mm, and the thickness of the slice sheet of 3 mm or more is not preferable because it is not useful for adjusting the amount of impregnation. Moreover, if it is not an open cell, it will become difficult to fully impregnate and hold cosmetics etc.

The surface of the slice sheet has large irregularities that are generated when the bubbles of the open-cell sponge are cut by the slice blade as described above. It is larger than the irregularities due to the bubbles that it has.
And, one surface of the slice sheet formed by slicing the open-cell sponge forms an application surface, and the other surface of the slice sheet is a recess formed by roughening the surface by the slice blade, and the foam originally possessed by the open-cell sponge A coating layer may be provided in close contact with a recess formed by combining two types of recesses formed by cutting the recesses in the shape of the inner surface thereof. In this case, the surface of the slice sheet on the coating layer forming side is adhered to the surface of the elastic base material so that the coated surface side of the slice sheet faces the surface.

As the coating layer, as described above, the coating layer is a layer that functions in close contact with the concave shape existing on the surface of the slice sheet. Therefore, the coating layer that exists in the concave portion is thick and the coating layer that exists in the convex portion. Is formed relatively thin. The thickness of the coating layer is 2 to 50 μm, more preferably 2 to 20 μm, but this thickness is an average thickness when the coating layer is formed on the base film through the release layer before thermal transfer. It is the same thickness as the thickness.
As a result of the coating layer being formed so as to be in close contact with the concave shape, the concave portion is filled with a passage communicating with the slice sheet, and is not in a state of communicating with the bubbles. And, when using the cosmetic chip, the cosmetic material or the like impregnated in the surface layer formed from the slice sheet does not reach the concave portion, so it does not stay in the concave portion, and the thickness of the slice sheet It becomes possible to apply accurately according to the impregnation amount determined by the above and a predetermined application amount. At the same time, it is possible to prevent excessive cosmetic material from being absorbed by the cosmetic chip, to generate sound during use, and to prevent wrinkles on the coated surface as it is used.

As a component of the film to be used as the thermal transfer layer provided on the release layer, an impermeable film is formed in close contact with the unevenness. As a flexible resin film component, a polyester urethane resin having a tensile breaking force of 45 to 60 MPa and a tensile breaking strain of 500 to 700% is preferable.
A more preferred tensile fracture force is 48 to 53 MPa, and a more preferred tensile fracture strain is 550 to 650%. If the tensile fracture force and tensile fracture strain are smaller than this range, the film is easily torn, and if it is larger, the adhesion is poor and the slice sheet cannot be fully covered with the concave portion. I can't do it. In order to form a thermal transfer layer having a thickness of 2 to 50 μm made of the polyester urethane, the resin is dissolved in a solvent and applied to the surface of the release layer on the base sheet.

(Elastic base material)
FIG. 2 is an example of an elastic base material 2 having a spindle-shaped tip and a circular cross section used in the present invention, and a porous resin material having elasticity such as NBR, NR, SBR, EPDM, polyethylene, polyurethane, Or it forms from resin materials, such as an elastomer represented by silicon | silicone and TPU.
This elastic base material 2 requires a certain range of hardness, but if it is too hard, it cannot sufficiently exhibit elasticity, and the cosmetic chip becomes difficult to be used at the time of use. Can be difficult.
If the elastic base material 2 is too soft, so-called stiffness is eliminated. Therefore, when the elastic base material 2 is used, the cosmetic chip is deflected and applied by pressing the cosmetic chip against the skin surface using the repulsive force. It becomes difficult.
The reason why the elastic base material has a circular cross section in the plane perpendicular to the axial direction is that the elastic base material is plate-shaped, for example, even when the cosmetic chip is bent using elasticity. Depending on the direction, the direction may be sufficiently bent or not, so that the cross section needs to be circular in order to prevent such a direction from being generated.
It should be noted that it may be such that it does not feel a difference in bending due to such directionality in use, and in that case, an elastic base material having a regular polygonal cross section can be used.

As described above, the elastic base material is inserted into the bag-shaped application part 1, and the bag-shaped application part 1 is covered on the elastic base material 2 with an adhesive or the like, and can be fixed with the adhesive. It is required to be a size. Therefore, it is clear that the size depends on the size of the inner diameter of the application part 1.
The shape is also determined by the shape of the inner surface of the bag-shaped application part 1.

(Cosmetic chips)
FIG. 3 is a diagram of a cosmetic chip formed by combining the application part 1 and the elastic base material 2 shown in FIGS.
A cosmetic chip shown in FIG. 3 can be obtained by inserting a spindle-shaped part at the tip of the elastic base material 2 into the inner surface of the bag-shaped application part 1 and fixing it with an adhesive or the like.
Of the elastic base material 2, the part a that is not inserted into the application part 1 and that is exposed on the outer surface is used to support a cosmetic chip when used, and the support part of a hand-held cosmetic tool is inserted into the part. Alternatively, the cosmetic chip can be fixed to a hand-held tool for use in makeup by holding the part with a support tool of a hand-held cosmetic tool (not shown).
Of course, the part a may not be formed, and the entire elastic base material may be covered with a bag-shaped application part. In this case, by supporting or gripping the portion of the handheld cosmetic tool supporting part or gripping part covered by the bag-shaped application part as far as possible from the tip of the cosmetic chip, The cosmetic chip of the present invention can be fixed.

The support is a member for supporting the application part of the cosmetic chip at one end thereof and holding it with a finger while directly or after being connected to a supporting member. At the other end of the support tool, for example, a tool used during makeup, such as a makeup brush, can be provided, or both ends of the support tool may be used as application portions.
The support may or may not have elasticity, but it is preferable in that it has a certain degree of elasticity so that the application part 1 can be brought into close contact with the skin surface during application. Also, the support is preferably non-liquid-absorbing, and if it has liquid-absorbing properties, liquid cosmetics are absorbed and the elasticity and other properties of the support itself change, so that handling properties and cosmetic applicability are improved. May be inferior.

The tip of the cosmetic chip of the present invention may have a straight line or a flat surface. In that case, the cosmetic chip may have a so-called linear shape with a flat end edge as viewed from the front.
The shape of the tip may be a straight line as shown in FIG. 4A, and the shape of the application part 1 is not limited to those shown in these drawings, and may be various shapes.

  FIG. 4B is a side view of the cosmetic tip shown in FIG. 4A, and the tip of the cosmetic tip is not limited to the thickness shown in the figure, and may be thicker or thinner. The thinner one can draw a finer line when applying the eye, and the double-width eye can be applied more pinpointly.

  Further, once used cosmetic chips, there are resident bacteria on the skin attached during use. For example, when a water-based cosmetic or the like is attached to the cosmetic chip, the cosmetic chip generates odor due to propagation of the resident bacteria. In addition, cosmetic chips that have been washed after use and contain moisture will similarly generate odors due to the propagation of varicella and the like present in the moisture. However, if an antibacterial agent is contained in the coating part 1, the antibacterial agent gradually diffuses into the cosmetic chip and can prevent or sterilize the growth of resident bacteria and chickenpox, etc. Occurrence can be prevented.

  Antibacterial agents that can be used for such applications may be arbitrarily selected from known antibacterial agents such as silver-based antibacterial agents such as silver zeolite and silver-containing glass, and antibacterial agents that can be used for cosmetics. it can. Among these, silver antibacterial agents are preferable from the viewpoints of antibacterial properties, chemical stability, and safety to the human body, such as not irritation of the skin.

Thus, it is necessary to mix an antibacterial agent in the application part 1 from the viewpoint of preventing the generation of odor.
If an antibacterial agent is to be blended in the application part 1, if these materials are vulcanized foams, the antibacterial agent and the sulfur compound react to lose antibacterial properties, and foaming is performed by a wet method. Even if an antibacterial agent is added in the method for obtaining the body, for example, a silver-containing antibacterial agent is also eluted together with the soluble particles that are eluted to form bubbles in the liquid. Antibacterial properties cannot be exhibited because no residue remains. For this reason, it is preferable to mix | blend an antibacterial agent with respect to the foam which is not a vulcanized foam and the foam by a wet method.

  In addition, the application part 1 can contain known additives for resins such as fragrances, colorants, fillers, and the like, if necessary. If a colorant is used, the color varies depending on the surface of the cosmetic chip. It is possible to change or draw a pattern on the cosmetic chip surface.

When performing makeup using such a cosmetic chip 1, a cosmetic chip with a handle as shown in FIG. 5 can be obtained. At that time, the base part 4 is connected to one end of the handle part 3 which is a grip part for a hand-held cosmetic tool, and the cosmetic chip is connected via the base part 4.
As the material of the handle portion 3, a resin or a metal is preferable, and a material having a certain degree of elasticity and a little is preferable. By providing elasticity, the cosmetic tip is brought into contact with the skin surface with a constant force during makeup.

The base part 4 has a cylindrical shape made of metal, one end is inserted into the end of the handle, and the other end is a part a of the cosmetic chip 1 as shown in FIG. Can be interpolated, or if it is a cosmetic chip as shown in FIGS. 1 and 2 that does not have the part a, the root portion can be interpolated into the base 4.
Since the base part 4 does not deform and lacks flexibility, even when the makeup is made with the handle part 3 that causes a certain degree of bending, the base part 4 can securely attach the cosmetic chip to the handle part 3. So that the cosmetic chip can be brought into contact with the skin surface with a certain force during makeup.

  The handle 3 and the base part 4 can be fixed and the base part 4 and the cosmetic chip 1 can be fixed by an adhesive such as an epoxy resin. Alternatively, the cosmetic chip 1 can be exchanged by providing a mechanism for allowing the cosmetic chip 1 to be reduced in diameter and expanded at the end of the base part 4 on the side where the cosmetic chip 1 is inserted. The chip can also be fixed. In this case, it fixes without using an adhesive agent.

It is preferable that the cross-sectional shapes of the handle portion 3 and the base portion 4 are easy to hold in the hand and do not bend only in a specific direction. In order to exhibit the above effects, the cross-sectional shape is therefore a circle, a pentagon or a hexagon. The length of the handle portion 3 needs to be 20 to 70 mm, which is easy to get familiar with fingers, and the length of the base portion 4 needs to be 5 to 30 mm.
The thickness of the handle portion 3 and the base portion 4 is such that it can be pinched by a finger, and the thickness of the portion held by the finger of a normal cosmetic tool is appropriate.

  Hereinafter, although the cosmetic chip | tip of this invention is demonstrated based on an Example, this invention is not limited to this.

The raw material of the open cell polyurethane sponge obtained by the wet method, which is a porous member, is sliced to a thickness of 2.5 mm, washed, dried, and then cut into a substantially triangular shape by punching. .
Two pieces of this cut polyurethane sponge are prepared, and these edge portions are bonded, welded, and stitched together to form an application portion of a cosmetic chip.
On the other hand, the NBR sponge, which is an elastic base material that is polished and shaped into a spindle shape, is prepared, and the adhesive layer is formed on the surface of the elastic base material or the adhesive layer is formed on the inner surface of the application portion. A chip application part is prepared. Next, the application part of the cosmetic chip is fixed to the tip part of the elastic base material by the adhesive while the elastic base material is inserted into the application part of the cosmetic chip. This is dried and sterilized to produce a cosmetic chip.

(Chip bending test)
Regarding the cosmetic chips of the present invention and the comparative example, it was tested whether their bendability differs depending on the direction.
The measurement sample of the present invention is an elastic substrate made of NBR sponge having a spindle-shaped tip and a circular section (diameter 6.7 mm), and a porous member made of polyurethane sponge having a thickness of 2.5 mm on the surface. The cosmetic chip provided is a comparative example, in which a porous member made of polyurethane sponge similar to the present invention is provided on the surface of an elastic base material made of nylon having a width of 5 mm and a thickness of 0.8 mm. It is a cosmetic chip.

A bending tester was used to fix the chip to the jig, and the bending strength when the 3 mm jig was moved upward at a speed of 100 mm / min was measured.

  From the above results, it was revealed that the chip of the present invention has no direction dependency with respect to the chip of the comparative example which is an existing cosmetic chip. This difference is due to the fact that the chip of the present invention has a circular cross-section as the core material, while the chip of the comparative example employs a plate-shaped core material. For this reason, the degree of bending differs depending on the measurement angle, that is, how the sample is set at the time of measurement. This means the angle of the chip at the time of use, and the applicability differs depending on the degree of bending between the two.

(Chip usage test)
Powder eye shadow (main color) was applied to the entire eye hole in a state of being picked up on the entire cosmetic chip of the present invention. This chip is smooth to the skin, and can easily be applied to a wide surface such as an eyehole or the entire eyelid, and can move freely without feeling the hardness of the core of the chip.
