Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a puff such as a cosmetic puff containing cosmetic powder such as white powder and a medicinal puff containing medicinal powder such as baby powder for infants.

[0002]

Conventionally, absorbent cotton has been used as a cosmetic puff. In recent years, as a disposable makeup puff, JP 20
The form as described in 01-104041 is beginning to be commercially available. This makeup puff has a shape as shown in FIGS. 1 and 2, and is a bag 1 made of a nonwoven fabric 2 in which absorbent cotton 6 is stored. The bag 1 has a substantially quadrangular pillow shape, and two opposite sides of the four sides are sealed to form a sealing portion 3,
The other two opposite sides are bent portions 4 only by bending the nonwoven fabric 2. Between the seal parts 3 and 3 on both sides,
There is a laminated part 5 in which the non-woven fabrics 2 are laminated, and fingers are inserted between the laminated layers, and the face and body are lightly tapped to remove sweat and fat. In addition, by inserting fingers between the layers, a separately prepared makeup powder such as white powder is applied to the surface of the non-woven fabric, the face or body is lightly tapped, and the makeup powder such as white powder is attached to the face or body.

However, if the makeup puff and the makeup powder such as white powder are separated, there are the following drawbacks. That is, it is complicated to attach the makeup powder to the makeup puff, the makeup powder cannot be used up to the end, the remaining makeup powder is wasteful, the container storing the makeup powder must be discarded, and the waste is There was a drawback that it would increase.

[0004]

Therefore, the present inventors thought that all of the above-mentioned drawbacks could be solved by putting a makeup powder inside the makeup puff described in JP 2001-104041 A. Therefore, it was thought that the makeup powder should be mixed in the absorbent cotton of this makeup puff, and that the nonwoven fabric constituting the bag should be provided with an opening so that the makeup powder can be exposed to the outside. However, it is difficult for the makeup powder to be retained in the absorbent cotton, and during manufacture or transportation, the makeup powder passes through the non-woven fabric and then exits to the outside. There was a case that the amount of was reduced.

Therefore, the inventors of the present invention, while conducting various experiments through trial and error, shorten the fiber length of each cotton fiber constituting the absorbent cotton, so that powders such as cosmetic powder and medicated powder are absorbent cotton. It has been found that they are more likely to be retained inside. The present invention has been made based on such findings.

[0006]

That is, the present invention comprises a bag made of a non-woven fabric, a group of crushed cotton fibers contained in the bag, and a powder held in a gap between the crushed cotton fibers, The non-woven fabric is provided with a large number of openings having a size that allows the powder to pass through, and the crushed cotton fiber is obtained by crushing cotton fiber to shorten its fiber length. It's about the puffs.

The puff according to the present invention comprises a bag 1 made of a non-woven fabric 2, a group of crushed cotton fibers 11 contained in the bag 1, and a powder 1 held in a gap between the crushed cotton fibers 11.
It consists of 2. Basically, the bag 1 may have any shape.
It is preferably shaped as described in 001-104041. That is, it is a substantially quadrilateral pillow shape, and two opposing sides of each of the four sides are sealed (the sealed portion serves as the sealing portion 3), and the other two opposing sides of the nonwoven fabric 2 are bent. It is only formed (the bent portion becomes the bent portion 4), and a shape having a portion 5 in which the nonwoven fabrics are laminated between the two sealed sides is preferable.
Further, the method of use is also the method described in JP 2001-104041 A, by inserting fingers between the laminated portions 5 and tapping on the face, body or the like.

As the non-woven fabric 2 which is the material of the bag 1, a large number of openings are formed such that when the face, body, etc. are tapped, the powder 12 contained in the bag 1 passes and goes out. You must use what you have. Specifically, use a relatively coarse non-woven fabric and one in which the constituent fiber gaps are automatically opened, or use a dense non-woven fabric with perforated holes. Good. The shape of the opening is not limited to a circle, but may be a quadrangle or an irregular shape. And, as for the size of the openings, it is generally preferable that the average diameter is about 0.07 to 0.15 mm. Here, the diameter means the diameter of a circle when the shape of the opening is a circle, but when it is a quadrangle or an irregular shape, the diameter of a virtual circle having an area equivalent to this area. It means that. If the average diameter is less than 0.07 mm, although depending on the average particle diameter of the powder 12, the powder 12 may pass through the non-woven fabric 2 and may not easily come out. If the average diameter exceeds 0.15 mm, not only the powder 12 but also the crushed cotton fibers 11 may be likely to come out. Open hole density is 400-800 /
It is preferably about cm ² . Opening density is 400 ~
If it is less than 800 pieces / cm ² , the powder 12 may pass through the nonwoven fabric 2 and may not be uniformly exposed to the outside.
If the density of openings exceeds 800 / cm ² , powder 1
There is a risk that the amount of 2 will be too large.

As a method of manufacturing such a nonwoven fabric 2,
Create a relatively coarse non-woven fabric by a conventionally known method,
Alternatively, the nonwoven fabric obtained by a conventionally known method may be provided with openings by a predetermined means. In particular, the preferred manufacturing method in the present invention is the water needling method. That is, it is a method in which a high-pressure water column flow is applied to the fibrous web so that the constituent fibers in the fibrous web are entangled with each other. In this case, when the fiber web is supported by mesh fabric and subjected to high-pressure water column flow, the high-pressure water column flow trace (the place where the high-pressure water column flow collides with the intersection point of the mesh fabric) automatically becomes a small opening, making it easy. Thus, the nonwoven fabric 2 used in the present invention can be obtained. Particularly, when the basis weight of the fibrous web is, for example, about 50 g / m ² or less, the nonwoven fabric 2 having pores can be easily obtained. The basis weight of the nonwoven fabric 2 used in the present invention is 30 to 70 g / m ²
It is preferably about the same.

As the fibers forming the non-woven fabric 2, conventionally known fibers are used, but generally, hydrophilic fibers are preferable. This is because sweat on the face and body can be absorbed well. Among the hydrophilic fibers, cotton fibers are preferable. If cotton fiber is used, the seal portion 3 can be easily created. That is, when the nonwoven fabric 2 enclosing the crushed cotton fibers 11 is pressed, hydrogen bonds are generated between the crushed cotton fibers 11 and the cotton fibers forming the nonwoven fabric 2 at the pressed portion, and the nonwoven fabric 2 and the crushed cotton fibers 11 group are integrated. Therefore, the seal portion 3 is easily formed.

A bag made of the non-woven fabric 2 contains 11 groups of crushed cotton fibers. The crushed cotton fiber 11 is obtained by crushing a cotton fiber to shorten its fiber length. Specifically, the cotton fiber has an average fiber length of 10 to 100 mm, and is crushed to have an average fiber length of 4 to 9 mm. The average fiber length is JISL-
It is measured according to the method described in 1019.
If the average fiber length of the crushed cotton fibers 11 exceeds 9 mm, the gap between the crushed cotton fibers 11 becomes too large, and it may be difficult to hold the powder 12. When the average fiber length of the crushed cotton fibers 11 is less than 4 mm, the crushed cotton fibers 1
1 itself may pass through the nonwoven fabric 2 and go out.

The crushed cotton fibers 11 may be crushed non-defatted cotton fibers, or may be crushed defatted cotton fibers (absorbent cotton). In terms of usefulness as a cosmetic puff or a medicated puff, it is preferable to use a crushed absorbent cotton. Crushing cotton fiber and crushing cotton fiber 1
The method for obtaining 1 is to introduce the cotton fiber into a crusher such as a crusher, a crusher, or a punching machine. The crushing machine cuts the cotton fibers to reduce the initial fiber length to about a fraction, and the crushed cotton fibers 11 having a short fiber length are obtained. Further, the basis weight of the 11 groups of crushed cotton fibers is preferably about 100 to 150 g / m ² , and the thickness (no load) is preferably about 3 to 10 mm. This mass and bulkiness are easy to use as a puff.

Powder 12 is mixed in 11 groups of crushed cotton fibers. As the powder 12, a conventionally known powder is used, and for example, cosmetic powder such as white powder, medicinal powder such as baby powder for infants and the like are used. The average particle size of the powder 12 is preferably 100 μm or less. If the average particle size exceeds 100 μm, the powder 12 may be difficult to come out through the nonwoven fabric 2. The amount of powder 12 is 0.1
It is preferably about 1.0 g, particularly 0.2 to 0.5
It is more preferably about g. When the amount of the powder 12 is less than 0.1 g, it becomes difficult to attach a sufficient amount of the powder 12 to the face or body when using. Further, if the amount of the powder 12 exceeds 1.0 g, the powder 12 may adhere to the face or body too much.

The powder 12 used in the present invention preferably has a composition of talc powder, calcium carbonate powder, amino acid-based powder and fragrance. The average particle size of talc powder is preferably about 12 to 16 μm, and the average particle size of calcium carbonate powder is preferably about 1 to 3 μm. This average particle size is measured using a particle size distribution laser analyzer manufactured by Shimadzu Corporation. As the amino acid powder, Amihope LL manufactured by Ajinomoto Co., Inc.
Is preferable, and the average particle size is 10 to 20 μm.
It is about m. In addition, this average particle diameter is measured using "HORIBA RA-700" by Horiba Ltd. The powder 12 having such a composition is
It imparts good slipperiness to the face and body and is suitable as a makeup powder.

The powder-filled puff according to the present invention can be basically manufactured by the following method (FIG. 4). That is, first, on the surface of the band-shaped nonwoven fabric 21, the crushed cotton fiber 1
1 is sprayed and deposited to form a group of crushed cotton fibers 11 group, and then powder 12 is sprayed from above the group of crushed cotton fibers 11 group. At this time, suction (suction) 22 is performed from the back surface of the band-shaped nonwoven fabric 21 to slightly compress the crushed cotton fiber 11 group layer and to inject the powder 12 into the crushed cotton fiber 11 group layer. Thereafter, the laminate of the band-shaped nonwoven fabric 21 and the crushed cotton fiber 11 group layer is folded in three in the width direction as shown in FIG. And at an appropriate interval, for example, an interval of 6 to 8 cm,
The seal portion 3 is formed by pressing. As described above, if cotton fibers are used as the constituent fibers of the band-shaped nonwoven fabric 12, hydrogen bonding occurs between the cotton fibers and the crushed cotton fibers when pressed with high pressure in the presence or absence of water vapor. The seal portion 3 is formed. After that, the powder-containing puff according to the present invention is obtained by cutting the central portion of the seal portion 3.

The powder-filled puff according to the present invention generally has a length of 40 to 60 mm and a width of 65 to 85 mm.
It is a degree. The vertical direction is the direction in which the seal portion 3 is provided, and the horizontal direction is the direction between the seal portions 3 and 3. Also,
The puff containing powder according to the present invention has a thickness of 8 to 12 mm.
The mass is about 1.0 to 1.5 g.
The powder-filled puff according to the present invention is put in a box of several hundreds and sold.

[0017]

In the puff containing powder according to the present invention, the powder is held in the spaces between the crushed cotton fibers, and the powder and the crushed cotton fiber group are contained in a bag made of a non-woven fabric. The crushed cotton fiber is obtained by crushing the cotton fiber, and its fiber length is shorter than the initial fiber length. Therefore, the gap formed between the crushed cotton fibers having a short fiber length is narrower than the gap formed between the cotton fibers having a long fiber length.
For this reason, the powder is more likely to be held in the gaps between the crushed cotton fibers, and during manufacture and transportation of the powder-filled puff,
It is difficult for the powder to separate from the crushed cotton fiber group and to disperse to the outside.

On the other hand, since the non-woven fabric forming the bag is provided with openings through which the powder can pass,
When using, i.e., if you hit the face or body lightly with a powdered puff, the powder held in the gaps between the crushed cotton fibers will pass through the non-woven fabric, go out to the outside, and attach the powder to the face and body. You can

EFFECTS OF THE INVENTION Since the puffs containing powder according to the present invention have the above-mentioned effects, the powder is unlikely to spill out while being carried, and moreover, the powder can be well adhered to the face or body during use. Further, in the powder-filled puff according to the present invention, it is not necessary to carry the puff and the powder separately. Therefore, the powder-filled puff according to the present invention has the effect of being convenient to carry.
