Abstract

PROBLEM TO BE SOLVED: To obviate the infiltration of cosmetics into a cotton ball and to allow the easy application thereof on the skin by winding cotton fibers, applying a resin to the surface of a cotton ball part and forming a film layer having a good release property on the front layer part. SOLUTION: The cotton ball part 2 is formed by winding the cotton fibers 3 around the end of a stem. The resin 5 is applied on the outside surface of the cotton ball part 2 to form the thin film layer 4 on the front layer of the cotton ball part 2. A resin, such as silicone resin, having the good release property is used for the resin 5. The thickness of the film layer 4 is adequately about 0.1 to 0.3mm. The resin 5 penetrates into the gaps among the cotton fibers 3 entangled with each other and securely entangles with the cotton fibers, thereby forming the film layer nearly continuous as a whole. Further, microruggedness of diversified shapes exists on the surface of the film layer 4. Since the cosmetics are caught by the ruggedness, the spread of the cosmetics is extremely good. The resin 5 nearly fills the gaps among the cotton fibers 3 and forms nearly the continuous films, although small holes, etc., partly exist therein. The cosmetics, therefore, merely stick on the surface of the cotton ball part 2 and do not infiltrate the inside of the cotton ball.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a swab used for cosmetics, industry (cleaning precision equipment) and the like.

[0002]

2. Description of the Related Art Conventionally, a cotton swab has been made by wrapping a cotton fiber in a teardrop shape around the end of a thin shaft. And, this cotton fiber is merely entwined with each other and wound around. In addition, in order to prevent the fibers from fraying, some of the wound cotton balls are thinly coated with an upper paste on the outer surface thereof. However, this is merely gluing the entangled portions of the fibers together. As described above, in each of the conventional swabs, the cotton fiber is simply wrapped around the shaft end, and a gap remains between the fibers.

[0003]

As described above, the conventional cotton swabs have relatively good adhesiveness of cosmetics because of the presence of voids between fibers, but on the other hand, they have a problem that they are difficult to remove. Therefore, for example, even if you try to apply lipstick to a cotton swab and apply it to your lips, the lipstick does not transfer well to the lips, and even if you apply it strongly, the lipstick only soaks into the inside of the swab and it easily transfers to the lips. Absent. In addition, the cosmetic that has permeated the inside of the swab is no longer available and is wasted, so that the utilization efficiency of the cosmetic is poor and it is extremely uneconomical.

Further, even if the surface of the cotton ball portion is coated with the upper glue, the purpose is to prevent the fibers from fraying, so the coating amount is small, and there are still voids between the fibers. In that respect, it is no different from the above-mentioned non-paste type.

In view of the above points, the present invention provides a cotton swab which prevents the cosmetic from soaking into the inside of the cotton ball so that it can be easily applied to the skin and the like and the cosmetic is not wasted. .

[0006]

The technical means of the cotton swab of the present invention is a cotton swab having a cotton ball wound around the end of a thin shaft to form a cotton ball, and a resin is applied to the surface of the cotton ball. Attach
This is because a film layer that is flexible and has good release properties is formed on the surface layer.

Further, as the film forming resin, it is preferable to use a silicon resin such as silicone rubber. Further, the film layer is preferably 0.1 to 0.3 mm.

[0008]

In the swab of the present invention, the resin film is formed on the surface layer of the cotton ball portion. Then, the resin penetrates into the cotton ball portion to a certain depth and firmly entangles with the cotton fiber, and becomes a coating layer having a thickness of about 0.1 to 0.3 mm as a whole. Also, since there are many minute irregularities on the surface of the coating layer,
When the cosmetic material is attached, the unevenness catches the cosmetic material well, and the cosmetic material is well placed. Further, since this film has good releasability, when applied to the skin, the cosmetic material easily separates from the cotton ball portion and transfers to the skin, which makes it very easy to apply. Further, since the cotton ball portion is covered with the film layer, the cosmetic material only adheres to the surface and the cosmetic material does not soak into the inside of the cotton ball, so that the cosmetic material is not wasted. Furthermore, when it is used for cleaning precision equipment, dust adhering to the equipment can be efficiently wiped off, and no fiber dust is generated from the cotton ball portion.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the swab of the present invention will be described with reference to the drawings. 1 is an axis, usually 7-8 in length
cm, the shaft diameter is 1 to 3 mm, and the cotton ball portion 2 is provided at one end or both ends thereof. This cotton ball part 2 has a cotton fiber 3 at the end of the shaft 1.
Wrap around to make. The size and shape of the cotton ball portion 2 can be freely changed by adjusting the winding of the cotton fiber 3. FIG. 1 shows an example of an elliptical shape, FIG. 2 shows an example of a point with a slightly sharpened tip, and FIG. 3 shows an example of a teardrop shape. The size of the cotton ball portion 2 is usually 12 to 16 m in length.
m, the thickness is about 5 to 7 mm.

Resin 5 is applied to the outer surface of the cotton ball portion 2,
A thin coating layer 4 is formed on the surface layer of the cotton ball portion 2. As the resin 5, silicon resin (silicone oil, silicone rubber),
Fluororesin (trade name, Teflon), etc. with good releasability is used. The coating amount of the resin 5 is usually about 10 to 30 mg per cotton ball portion, which allows the coating layer 4 to have an appropriate thickness. The thickness of the coating layer 4 is preferably about 0.1 to 0.3 mm, more preferably 0.15 to 0.2 mm. If the coating material is less than this, a sufficient film cannot be formed, and on the contrary, if the coating amount is too large, the flexibility of the film deteriorates.

The method of applying the resin to the cotton ball portion 2 is arbitrary, and a roller transfer method, a spray method, a dipping method or the like can be used. The amount of application to the cotton ball portion 2 may be uniform over the entire surface, or the tip portion or the like may be partially applied in a large amount. In addition, the applied resin is subjected to a polymerizing treatment or the like to strengthen the adhesion with the cotton fiber and complete as a film layer.

The detailed state of the coating layer 4 is shown in FIG. As can be seen from this figure, the resin 5 permeates into the spaces between the cotton fibers 3 which are intertwined with each other, and is firmly entangled with the cotton fibers, forming a substantially continuous coating layer as a whole.
Furthermore, the surface of the film layer 4 has minute irregularities of various shapes. The cosmetics are caught by these irregularities, so the cosmetics are very well applied. Further, the resin 5 substantially fills the gaps between the cotton fibers 3 and is a continuous film although there are some small holes and the like. Therefore, the cosmetic only adheres to the surface of the cotton ball portion 2 and hardly penetrates into the inside of the cotton ball. Furthermore, since the coating layer 4 is extremely thin, about 0.1 to 0.3 mm, it is highly flexible and, in combination with the cushioning effect of the cotton inside, it is suitable for applying cosmetics and applying it to the skin. It has suitable elasticity. In addition, since the resin having good releasability is used, the cosmetic easily separates from the cotton ball portion 2 and transfers to the skin when applied to the skin.

[0013]

Example: A cotton fiber 3 is attached to the end of the shaft 1 having a shaft diameter of about 2.5 mm.
The cotton ball part 2 (length 1
2 to 15 mm and a thickness of 4.5 to 6 mm) were formed. Silicone rubber was applied to each of these cotton ball parts 2 to form a silicone rubber film layer on the surface of the cotton ball part. Application amount is 1
Experiments were carried out with 4 kinds of 0, 15, 20, 30 mg. With any shape of the cotton ball part, the amount of application is a little less with 10 mg,
At 30 mg, the number of eyes was rather large, and 15 mg and 20 mg were appropriate amounts. The thickness of the coating layer 4 formed by permeation of the silicone rubber is about 0.1 mm for 10 mg, about 0.2 mm for 15 mg, and 20 on average for all surfaces.
0.25 mm for 30 mg and about 0.1 mm for 30 mg.
3 mm. The resin was applied by applying a low-viscosity liquid silicone rubber using a liquid precision metering device. As a result, the amount of silicone rubber applied could be controlled with high accuracy.

When a cosmetic application test was conducted using a cotton swab having a resin coating amount of 20 mg, the adhesiveness of the cosmetic to the cotton ball portion was good in any of the shapes, and when applied to the skin, The cosmetic was well separated from the cotton balls and transferred to the skin, and the spreadability was good, making it very easy to apply. In addition, when a test was conducted after the application, the cosmetics hardly penetrated into the inside of the cotton ball portion. The shape of FIGS. 1 and 3 was suitable for applying lipstick and eye shadow, and the shape of FIG. 2 was suitable for applying eye line.

The present invention is not limited to the above-mentioned embodiments, but can be freely modified within the scope of the claims. In particular, the shape of the cotton ball portion, the type of coating layer forming resin, the coating method, etc. are free.

[0016]

EFFECTS OF THE INVENTION The swab of the present invention has a coating layer on the surface layer of the cotton ball portion, so that the cosmetic material can be well applied to the cotton ball portion and the cosmetic material can be applied to the cotton ball when applied to the skin. It is easy to remove from the part and very easy to apply. Further, since the cosmetic does not soak into the inside of the cotton ball, there is no waste of the cosmetic and it is economical. Furthermore, it is hygienic because it can be disposable. In addition to cosmetics, it also exhibits unprecedented excellent performance in the application and cleaning of various substances on equipment for industrial purposes.
