Abstract

PROBLEM TO BE SOLVED: To solve problems that a joined part is hardened if surface sheets of a cosmetic puff are joined with each other through the heat bonding or simple hydrogen bond, an edge part after the cutting is sharp, and the sense of incompatibility easily occurs when the cosmetic puff is used. SOLUTION: An internal cotton 3 comprising hydrophilic and water-holding fibers 4 such as rayon and cotton and hydrophobic fibers generating no hydrogen bond which are appropriately mixed is wrapped in a surface sheet 2, and the surface sheet 2 and the internal cotton 3 are pressed at the temperature not higher than the melting point to form a sealed part 1a. Since the hydrophobic fibers 5 are contained, the hydrogen bond of the sealed part 1a can be mitigated. Further, since the hydrogen bond at a cut part 1c1 can be mitigated, no hard edge parts are left behind in the cut part 1c1. Thus, the feeling with the skin becomes excellent.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic puff (cosmetic cotton) used for removing makeup or makeup or removing nail polish, and a method for producing the same.

[0002]

2. Description of the Related Art Conventional cosmetic puffs (cosmetic cotton) include those described in, for example, Japanese Utility Model Laid-Open No. 60-151424 and Japanese Patent Application Laid-Open No. 2-26969.

[0003] The decorative puff described in Japanese Utility Model Application Laid-Open No. 60-151424 is obtained by covering a fiber web (filling) of an inner layer with a surface material. The edges parallel to the direction are joined by pressure bonding or heat fusion.

However, in the publication described in the above publication,
Since both ends in the longitudinal direction of the cosmetic cotton are open, the batting easily falls off from the both ends. In addition, since the edge of the cosmetic puff is heat-sealed, the heat-sealed seal portion becomes hard, and this hard portion hits the skin, giving a sense of incongruity to a user of the cosmetic puff.

Japanese Patent Application Laid-Open No. 2-26969 discloses a method of compressing a sheet-like cotton band at both ends of a cotton wool to form a hydrogen bond between OH groups of cellulose molecules exposed on the mutual surface of cotton fiber. To prevent the fiber from coming off.

[0006] However, when the cotton fibers are hydrogen-bonded by hydrogen bonding by compression, the edge of the compressed and hydrogen-bonded portion is considerably hard. Moreover, when the hydrogen-bonded portion is cut into individual decorative puffs, the hydrogen bond is further strengthened by the pressure generated by the cutting edge. For this reason, the edge part of the cosmetic puff after cutting is very hard, and gives an uncomfortable feeling when the cosmetic puff hits the skin of a person using the cosmetic puff as in the case of heat welding.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and does not form a sealed portion due to hydrogen bonding or a hard portion due to joining at an end portion after cutting, so that a person using a decorative puff can be used. An object of the present invention is to provide a cosmetic puff that does not give a feeling of strangeness and a method for producing the same.

[0008]

According to the present invention, there is provided a surface sheet made of hydrophilic fibers which comes into contact with the skin during use, and a batting made of hydrophilic fibers, wherein the batting is wrapped by the surface sheet. In a decorative puff in which a sealing portion in which the topsheet and the batting are hydrogen-bonded in a pressurized state is formed, at least in the portion of the sealing portion, a hydrogen bond is formed to one of the topsheet and the batting. The present invention is characterized in that it contains hydrophobic fibers that relax.

In the present invention, since at least one of the topsheet and the batting contains the hydrophobic fiber for relaxing the hydrogen bond, the sealing portion itself that has been hydrogen-bonded under a pressurized state becomes relatively flexible. Therefore, the uncomfortable feeling when the sealing portion hits the skin of the user can be reduced.

Further, in the present invention, a non-pressed area is provided outside the sealing section, and in the non-pressed area, the topsheet and the batting are in contact with an outer edge of the sealing section. It is preferable that the cutting is performed at a position with an interval.

As described above, if an unpressurized region is provided outside the sealing portion, the unpressed portion comes into contact with the skin, and even if the sealing portion is hardened. The discomfort of the user can be reduced. Also, when the unpressed area is cut, the surface sheet and the batting are pressurized by the pressure of the cutting edge, and the hydrophilic fibers tend to generate hydrogen bonds. However, if the cut portion contains a hydrophobic fiber, the hydrogen bond due to the cut is alleviated, and the cut edge becomes soft.

In the present invention, the hydrogen bond itself in the sealing portion is reduced, and the sealing portion itself is relatively flexible. Therefore, even if the cut portion is cut at the sealing portion without leaving the unpressed area, the cut edge portion can be made soft and the contact with the skin becomes soft.

It is preferable that the hydrophobic fiber is contained in a range of 5% by mass to 40% by mass with respect to the mass of the topsheet and the batting in the sealing portion. For example, the batting is a mixture of the hydrophilic fibers and the hydrophobic fibers.

[0014] Alternatively, the batting is formed by alternately forming layers of hydrophilic fibers and hydrophobic fibers. in this case,
The layer of hydrophobic fibers may be a woven or non-woven fabric.

[0015] The topsheet is a nonwoven fabric comprising hydrophilic fibers and the hydrophobic fibers.

When forming the nonwoven fabric, the nonwoven fabric has a surface layer and a back layer, and the surface layer is formed only of hydrophilic fibers and the back layer is formed only of hydrophobic fibers. The layer may include more hydrophilic fibers than the back layer, and the back layer may include more hydrophobic fibers than the front layer, or the nonwoven may include a front layer and an intermediate layer. And a back layer, wherein the front layer and the back layer are made of only hydrophilic fibers, and the intermediate layer is formed of only hydrophobic fibers, or the front layer and the back layer are more than the intermediate layer. The intermediate layer may include hydrophilic fibers, and the intermediate layer may include more hydrophobic fibers than the front surface layer and the back surface layer.

Alternatively, the topsheet is a laminate of a nonwoven fabric formed of hydrophilic fibers and a nonwoven fabric formed of hydrophobic fibers.

The hydrophobic fiber is, for example, at least one of polyester fiber, acrylic fiber and polyolefin fiber.

Next, the method for producing a cosmetic puff according to the present invention comprises:
(A) Both using a surface sheet and a batting mainly composed of hydrophilic fibers and containing at least one of the hydrophobic fibers, the batting of a predetermined basis weight is continuously formed on the belt-shaped top sheet along the longitudinal direction of the top sheet. (B)
Wrapping the batting with the topsheet so that both edges in the width direction of the band-shaped topsheet overlap, (c) wrapping the batting with the topsheet in a predetermined dimension in the longitudinal direction of the topsheet. Forming a sealing portion in which the surface sheet and the hydrophilic fiber forming the batting are hydrogen-bonded by pressurizing at an interval and pressing at a temperature lower than the melting point of the hydrophobic fiber, (d). A step of separating into individual makeup puffs whose front and rear portions are sandwiched by the sealing portion.

In the above (c), in the step (c), the two sealing portions are formed at a position spaced apart from each other by the predetermined dimension with a gap therebetween, and a gap is formed between the sealing portions. It is preferable that an area not to be pressed is provided, and in the step (d), cutting is performed at the area not to be pressed to separate into individual makeup puffs.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing a first embodiment of a decorative puff according to the present invention, and FIG. 2 is a sectional view taken along the line II-II of FIG.

The decorative puff 1 shown in FIGS. 1 and 2 has a batting 3 wrapped around a topsheet 2. The topsheet 2 and the batting 3 are sealed by sealing portions 1a at both ends in the directions Y1 and Y2 in the figure.

The topsheet 2 is a spunlaced nonwoven fabric formed of cotton, which is a hydrophilic fiber, or a web containing silk in cotton. Alternatively, the above-mentioned cotton or a woven fabric composed of cotton and silk may be used. Since the topsheet 2 is made of cotton or cotton and silk, the topsheet 2 is soft and comfortable.

The batting 3 is a fiber web in which a hydrophilic and water-retaining fiber 4 such as rayon or cotton is mixed with a suitable amount of hydrophobic fiber 5 that does not cause hydrogen bonding.

In the sealing portions 1a, 1a, the topsheet 2 and the batting 3 are pressed and heated together.
As a result, hydrogen bonding occurs between the OH groups of the cellulose molecules between the hydrophilic fibers such as the cotton forming the topsheet 2 and the hydrophilic and water-retaining fibers 4 forming the batting 3. Due to this hydrogen bonding, the sealing portion 1a is securely closed, and the topsheet 2 is held in a bag shape.

In the first embodiment, the sealing portions 1a,
In 1a, not only the hydrophilic fibers forming the topsheet 2 and the hydrophilic and water-retaining fibers 4 forming the batting 3 but also the hydrophobic fibers 5 that do not cause hydrogen bonding are included. Therefore, the hydrogen bonding in the sealing portions 1a, 1a is reduced. Therefore, the sealing portions 1a are more flexible than those made of only hydrophilic fibers. Therefore, when it hits the skin, there is little irritation to the skin.

In the embodiment shown in FIG. 1, an unpressed area 1c is left outside the outer edge 1a1 of the sealing portions 1a, 1a by a minute width W, and the outer edge of this area 1c is cut. The section 1c1.

Since the unpressurized region 1c is left outside the sealing portion 1a, the pressurized sealing portions 1a, 1a can be prevented from directly hitting the skin, and The hits are softer.

Further, the edge of the region 1c is formed by a cutting portion 1c1.
When cutting is performed, the top sheet 2 and the batting 3 are pressed at the cutting portion 1c1 by the cutting edge of the cutter.
The pressurization also causes the hydrophilic fibers to easily form hydrogen bonds. However, also in the cut portion 1c1, since the hydrophilic fiber contains the hydrophobic fiber 5, the hydrogen bond due to the pressurization of the cutting edge is reduced, and a hard edge hardly remains in the cut portion 1c1.

As described above, according to the embodiment of the present invention, compared with the case where only the hydrophilic fiber is formed, the sealing portion 1 is formed.
a, 1a itself is flexible. In addition, sealing portions 1a, 1a
Are left unpressed and unsealed around the area 1c, and hard edges are less likely to be formed in the cut portions 1c1 of the area 1c. Therefore, the sealing portions 1a, 1
Even if the portion a or the cut portion 1c1 hits the skin, it is relatively flexible and does not give the user a feeling of strangeness.

Since the sealing portions 1a, 1a themselves are flexible as described above, in the present invention, the regions 1c, 1a,
Instead of forming 1c, the edges of the sealing portions 1a, 1a may be cut portions. Since the cut portions 1c1 and 1c1 themselves are flexible, even if the cut portions 1c1 and 1c1 directly hit the skin, there is little discomfort.

The mixing ratio of the hydrophobic fibers 5 is determined according to the surface sheet 2
It is preferably from 5% by mass to 40% by mass with respect to the total mass of the fibers forming the batting. If the mixing ratio of the hydrophobic fibers 5 exceeds 40% by mass, hydrogen bonding at the sealing portions 1a, 1a becomes weak, and the open end of the topsheet 2 cannot be reliably sealed. Occurs. When the mixing ratio of the hydrophobic fiber 5 is less than 5% by mass, the sealing portion 1
a, 1a, the hydrogen bond becomes too strong and the sealing portions 1a, 1a
a becomes too hard. Further, when the mixing ratio is less than 5% by mass, when the region 1c is cut as shown in FIG. 1, the cut portion 1c1 becomes hard and tends to have an edge shape. A more preferable range of the mixing ratio of the hydrophobic fibers 5 is 10% by mass to 3%.
0% by mass.

The batting weight (basis weight) of the batting 3 is 50 g /
m ^{2 to} 120 g / m ² are preferred. When it is less than the above range, the makeup puff 1 becomes thin, and the amount of water retention such as lotion decreases. If it exceeds the above range, the decorative puff 1 becomes too bulky, and when forming the sealing portions 1a, 1a, the amount of fibers in the portion to be pressed and heated becomes too large, and the sealing portion 1a, 1a The degree of sealing decreases.

The hydrophobic fibers 5 include a sealing portion 1a,
In order to make it difficult for heat fusion to occur during pressurization and heating when forming 1a, those having a high melting point are preferably used, for example, polyester fibers, particularly preferably PET.
(Polyethylene terephthalate) fibers, polypropylene fibers, or those having a side-by-side type short fiber structure or a core-sheath type short fiber structure made of the polyester and polypropylene are preferably used. Alternatively, acrylic fibers or polyolefin fibers may be used.

The fineness of rayon, which is the hydrophilic and water-retaining fiber 4 used for the batting 3, and the fineness of the hydrophobic fiber 5 are 1 to 10 deniers. From the viewpoint of touch, it is preferably in the range of 1.5 to 3.0 denier. The fiber length is 10-50
mm is preferable.

FIG. 3 is a sectional view of a decorative puff showing a second embodiment of the present invention. In the makeup puff 1A shown in FIG.
The batting 3 comprises an upper hydrophilic and water-retentive fiber layer 4a, a lower hydrophilic and water-retentive fiber layer 4b, and the fiber layer 4b.

FIG. 4 is a partially enlarged sectional view showing a decorative puff according to a third embodiment of the present invention. In the decorative puff of the present invention, the topsheet 2 may have a multilayer structure, but FIG. 4 shows an example using a topsheet 2A having a three-layer structure.

The topsheet 2A shown in FIG. 4 is composed of an outer nonwoven fabric 2a directly in contact with the skin and an inner nonwoven fabric 2c facing the batting 3.

Also in this embodiment, the sealing portions 1a, 1
a and the cut portion 1c1, a hydrophobic fiber layer is present in the intermediate layer 2b together with the hydrophilic fibers constituting the outer nonwoven fabric 2a and the inner nonwoven fabric 2c and the hydrophilic and water retaining fibers 4 constituting the batting 3. Therefore, hydrogen bonding between the hydrophilic fibers can be reduced.

The topsheet 2A may be formed of one or many nonwoven fabrics, and each nonwoven fabric may be composed of hydrophilic fibers and hydrophobic fibers.

FIGS. 5A and 5B show a fourth embodiment of the present invention. In FIG. 5 (A), the topsheet 2B wrapping the batting 3 is a single-layer nonwoven fabric, and the inside of this nonwoven fabric is a so-called two-layer nonwoven fabric having different fiber compositions between the surface layer 2B1 and the back layer 2B2. is there. The surface layer 2B1 is formed only of hydrophilic fibers, and the back layer 2B2 is formed only of hydrophobic fibers. Alternatively, the surface layer 2B1 and the back layer 2
B2 contains both hydrophilic and hydrophobic fibers, and the surface layer 2
B1 contains more hydrophilic fibers than back layer 2B2, and back layer 2B2 contains more hydrophobic fibers than surface layer 2B1.

FIG. 5B shows the top sheet 2C.
Is a so-called three-layer nonwoven fabric, and the surface layer 2
C1, an intermediate layer 2C2, and a back surface layer 2C3. The surface layer 2C1 and the back surface layer 2C3 are formed of only hydrophilic fibers, and the intermediate layer 2C2 is formed of only hydrophobic fibers.

In the present invention, the batting 3 may contain hydrophobic fibers only, the top sheet 2A may contain hydrophobic fibers, or the top sheet 2A may contain hydrophobic fibers.
Both the batting 3 and the batting 3 may contain hydrophobic fibers.

Next, a method for producing the above cosmetic puff will be described. 6 is a perspective view schematically showing a manufacturing process of the decorative puff shown in FIGS. 1 and 2, FIG. 7 is a side sectional view of the decorative puff, (A) is a sectional view before cutting, and (B) is a cutting. It is sectional drawing after.

As shown in FIG. 6, a soft and soft band-like top sheet 2 mainly made of cotton spunlace or cotton spunlace containing silk is fed in the feed direction (MD) by feed means (not shown). Sent.

In the first step (I), a batting 3 having a predetermined basis weight is continuously supplied and placed on the topsheet 2.
Here, the batting 3 is a mixture of hydrophilic and water-retaining fibers 4 such as rayon or cotton and an appropriate amount of hydrophobic fibers 5 that do not cause hydrogen bonding.

In the second step (II), a bag-like sheet is formed by bending both edges in the width direction of the topsheet 2 by guide means (not shown) so as to overlap each other. 3 is wrapped.

In the third step (III), the bag-like sheet is crushed by a pressing means (not shown) at a certain interval in the feeding direction (MD). As a result, two sealing portions 1a, 1a are formed in the portion having the predetermined interval and at a minute interval in the feed direction. At the portion where the two sealing portions 1a, 1a are formed, the plurality of decorative puffs 1 are connected by the connecting portion 1d. Here, in the sealing portions 1a, 1a, the topsheet 2 and the batting 3 are pressed together and pressed, and are heated at a temperature lower than the melting point of the hydrophobic fiber 5. As a result, in the sealing portions 1a, 1a, the hydrophilic fibers forming the topsheet 2 and the batting 3 are hydrogen-bonded. However, since the heating is at or below the melting point of the hydrophobic fiber 5, the hydrophobic fiber 5 does not melt, so that the sealing portions 1a, 1a are not heat-sealed or slightly heat-bond even if heat-sealed. It is only a degree of adhesion. Therefore, the hydrophobic fiber 5 functions to suppress and relax the hydrogen bond.

In the connecting portion 1d, the sealing portion 1a
The region 1c sandwiched by the sealing portion 1a and the sealing portion 1a is a region that is not pressurized. In the third step (III), as shown in FIG. Is not hydrogen bonded.

At this time, the surface sheet 2 and the batting 3 are pressed in the area 1c by the pressure of the cutting edge of the cutter. At this time, the hydrophilic fibers contained in the topsheet 2 and the batting 3 try to form hydrogen bonds. However, this cutting line T-
Since the hydrophobic fiber 5 is included in the portion of T, the hydrogen bond of the hydrophilic fiber is suppressed and relaxed when pressurized by the cutter.

According to the above steps, in each cosmetic puff,
As shown in FIG. 7B, an unpressurized region 1c is left outside the sealing portions 1a, 1a, but the cut portion 1c is formed.
In No. 1, since the hydrogen bond is relaxed as described above, the edge does not have a hard edge, and the edges of the topsheet 2 are slightly separated from each other.

The decorative puff having the structure shown in FIGS. 3 and 4 can be manufactured in the same manner by the steps shown in FIGS. 6 and 7.

[0056]

According to the present invention described in detail above, the sealing portion of the decorative puff can be made flexible, and the feeling of discomfort when the sealing portion hits the skin can be reduced.

Further, even when an unpressurized region is left outside the sealing portion, the hydrogen bond when this region is cut can be relaxed, and a hard edge is not formed at the cutting portion. Can make the skin feel less uncomfortable even when it hits the skin.
