Abstract

PROBLEM TO BE SOLVED: To provide a face-washing puff which is obtained by further improving a conventional face-washing puff and which is extremely superior in foaming.SOLUTION: The face-washing puff in which a part or all of a sponge core material is wrapped with a fibrous material, is characterized in that pores are formed in the sponge core material and an air layer is provided inside. Desirably, the sponge core material is a soft urethane foam in which a cell film formed in manufacturing is removed by an explosion method.

Description

The present invention relates to a puff used for makeup removal and face washing (hereinafter referred to as a face washing puff).

Conventionally used face-washing puffs are generally flat, for example, oval, mainly covered with a textile material such as a cloth, mainly a sponge core. Such face washing puffs mainly remove makeup, dirt, dirt, fat and the like, and various fiber materials have been proposed in consideration of the effect on the skin.

There exists patent document 1 as what considered the influence which a fiber raw material has on skin. It can remove fats and wastes that are harmful to beauty from the surface of the skin, and provides a cleansing puff with antibacterial, antifungal, and deodorant properties that does not adversely affect the skin. A fiber material covering the material is formed from a fiber loop pile fabric made by adhering a complex of deacetylated chitin and sericin to the fiber surface.

Adopting the above fiber material has excellent water absorption and drying properties, has resistance to mold, and has properties such as acid resistance, alkali resistance, oxidation resistance, reduction resistance and organic solvent, so it can be used for a long time. However, it is based on the result that it is not affected by cosmetics and face wash, and does not affect the skin.

Patent Document 2 aims to further improve facial beauty and health by more effectively removing dirt such as dirt and fat and waste products that clog deep pores and cause acne. It is a knitted pile knitted fabric as a fiber material, and the pile portion is a knitted or twisted fabric made of 10 to 90% microfiber and other spun yarns 90 to 10%. It is what.

On the other hand, as the sponge core material wrapped with these fiber materials, a soft urethane foam material is usually used and a foaming effect is required. However, the shape and structure are not particularly limited.

  The present invention provides a further improvement of the conventional face washing puff, and provides a face washing puff having extremely excellent foaming.

The gist of the present invention is a face washing puff formed by encapsulating part or all of a sponge core material with a fiber material, wherein a hole is formed in the sponge core material, and an air layer is present inside. It is applied to the face-washing puff. And preferably, a sponge core material consists of a flexible urethane foam which removed the cell membrane formed at the time of manufacture by the explosion method etc.

  The present invention is as described above, and when washing the detergent using such a face washing puff, since air is contained in the holes formed in the sponge core material, this is pushed out to act on the detergent, The effect was significantly improved.

FIG. 1 is a cross-sectional view showing a first example of a face washing puff according to the present invention. FIG. 2 is a cross-sectional view showing a second example of the face-washing puff of the present invention. FIG. 3 is a sectional view showing only a sponge core material showing a third example of the face-washing puff of the present invention. FIG. 4 is a sectional view showing only a sponge core material showing a fourth example of the face-washing puff of the present invention. FIG. 5 is a sectional view showing a fifth example of the face-washing puff of the present invention.

The basic structure of the face-washing puff of the present invention is a structure in which a fiber material is encapsulated on one side or both sides of a sponge core material. It is also possible to do.

  The fiber material is not particularly limited, and a conventionally used material can be used as it is.

  The feature of the present invention resides in the sponge core material, in which one or a plurality of holes are formed in the sponge core material, and an air layer is present inside the holes during use. For this reason, when foaming the detergent sprinkled on the fiber material, a large amount of air is mixed from the inside of the sponge core material, and the foam can be extremely effectively foamed.

The sponge core material is usually a soft urethane foam material, which has a three-dimensional network structure by removing the cell film formed at the time of foaming, and has an excellent foaming effect. The number of cells is preferably about 10 to 60 cells / inch, and a plurality of flexible urethane foams having different numbers of cells can be used in an overlapping manner in order to improve foaming.

  Now, the hole formed in the sponge core material is not particularly limited. Usually, the hole may have a diameter of about 5 to 25 mm, and may be a through hole or a hole staying inside. Of course, it is preferable to make one or a plurality of holes. The through-hole can be processed very easily with a press.

  Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. FIG. 1 is a cross-sectional view of a face washing puff showing a first embodiment of the present invention. In the figure, reference numeral 10 denotes a face-washing puff, which is composed of a single piece of flexible urethane foam core material 1 from which the cell membrane has been removed and a pile knitted fiber material 2 that wraps the core material 1. It is elliptical in plan view. Of course, the shape is not particularly limited. The number of cells of the flexible urethane foam of the core material 1 is 25 ± 3 / inch.

The pile knitted fiber material 2 is a loop pile processed fabric using 30% microfiber (polyester fiber) and 70% normal polyester fiber.

Now, the core material 1 is formed with three through holes 3A having a diameter of 1 cm in the vertical direction. Accordingly, in a normal state, the air is encased in the fiber material 2 in a state where air enters the through hole 3A.

  For this reason, the inside of the face-washing puff 10 is in a state of containing air, and the air in the through-hole 3A of the face-washing puff 10 is well mixed with the detergent simply by including the detergent in the fiber material 2 and gently rubbing it. Foaming is very good.

FIG. 2 shows a second embodiment of the present invention, in which the pile knitted fiber material 2 is arranged only on one side of a soft urethane foam core material 1. Bonding is performed by any conventional method. This face-washing puff 10 also extremely improves foaming.

  FIG. 3 shows a third embodiment of the present invention, in which the core material 1 is composed of two layers of flexible urethane foam. The holes may be formed in only one layer or through two layers. 3B is a hole formed in only one layer, and 3C is a through-hole through which two layers pass. This face-washing puff 10 also extremely improves foaming.

  FIG. 4 shows a fourth embodiment of the present invention, in which the core material 1 is composed of two layers of flexible urethane foam. In this example, the hole 3D is included in the core material 1, and the bottomed holes 3d and 3d are formed in the opposed portions of the core material 1, and the holes 3D are formed to include them together. . This face-washing puff 10 also extremely improves foaming.

  FIG. 5 is a cross-sectional view of a face washing puff showing a fifth embodiment of the present invention. In this example, a relatively large through-hole 3A is formed in the core material 1, but the fiber material 2 is pushed into the hole 3A so as to have a recess 4, and the detergent is put into this to roughly approximate the detergent. There is also an advantage that the amount can be measured. The recess 4 may be a bottomed hole 3D. .

  In the present invention, air is included in the face washing puff so that the air is more easily mixed with the detergent, and the face washing puff is extremely foamy and is extremely easy to use regardless of age or sex. It is a puff and its practical value is high.
