Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those of ordinary skill in the art may easily implement the present invention. When it is said that a part "includes" a certain component throughout the specification, it means that other components may be further included without excluding other components, unless specifically stated to the contrary, and one or more It is to be understood that the presence or addition of other features, numbers, steps, actions, elements, parts, or combinations thereof, does not preclude in advance.

Referring to FIG. 1, the cleansing pad 100 is in a dry state in which moisture is not absorbed. The cleansing pad 100 is used to remove foreign substances such as cosmetics from the face while moisture is absorbed. The cleansing pad 100 is used to remove foreign substances in a state in which only moisture is absorbed without other additives (eg, ethanol), and skin troubles due to other additives do not occur. Therefore, it is convenient for the user to remove foreign substances such as cosmetics by using only water on the cleansing pad 100.

The cleansing pad 100 is not disposed of after being used to remove foreign substances, but can be reused through washing, so it is eco-friendly. In addition, since the cleansing pad 100 is a solid, not a liquid, a separate container for holding the cleansing pad 100 is not required, and storage and transport are easy.

Referring to FIG. 2, the cleansing pad 200 may include an upper pad 20, a middle pad 40, and a lower pad 60.

The upper pad 20 may include a first fabric, and the lower pad 60 may include a second fabric. The first fabric or the second fabric may be the same or different.

The first or second fabric may be a fabric for washing, and may be a fabric fabric treated with Velveteen, Chiffon, Flannel, or Laminate, but is not limited thereto. The laminated fabric fabric includes a thin synthetic resin film bonded to one side of the fabric fabric, thereby improving the bonding strength inside the fabric fabric.

*The first fabric or the second fabric may include a pile, which is a short fiber tightly planted in the form of a ring or hair, and the pile is a thread that is additionally inserted on the air fabric formed of warp and weft.

According to an embodiment, at least one of the first fabric and the second fabric may be in the form of microfiber. Alternatively, the first fabric may be microfiber, and the second fabric may be polyester.

The microfiber fiber 10 may be disposed on the upper surface of the upper pad 20 or the lower surface of the lower pad 60, and may be formed by pulling out a file included in the first or second fabric. The microfiber fiber 10 is a thread that is thinner than about one hundredth of the thickness of a hair, and may have a thickness of about 0.5 denier or less, and has excellent moisture absorption and foreign matter absorption.

The microfiber fiber 10 may remove foreign substances by directly contacting foreign substances such as cosmetics on the face while moisture is absorbed. In addition, since the microfiber fibers 10 are arranged very densely, by preventing ticks from inhabiting the space between the microfiber fibers 10, it can be hygienically safe even when it comes into direct contact with the skin.

The middle pad 40 may be disposed between the upper pad 20 and the lower pad 60. The first fabric included in the upper pad 20 (for example, a laminated fabric fabric) and the second fabric included in the lower pad 60 (for example, a laminate treated fabric fabric) have high bending properties. , Since the shape of the cleansing pad 200 is difficult to maintain, the cleansing pad 200 may maintain the shape of the cleansing pad 200 by including the middle pad 40 having a small bendability. Bendability is a property that a solid is bent under external force.

The middle pad 40 may include an elastic body made of a porous material, and the elastic body made of a porous material may be a sponge. Sponge can be manufactured using rubber or synthetic resin. In addition, the sponge has excellent moisture absorption and elasticity.

The cleansing pad 200 is used to remove foreign substances such as cosmetics from the face in a state in which a large amount of moisture is absorbed, based on the excellent moisture absorption power of the sponge, and thus has excellent cleaning power.

When the volume of the sponge absorbed by moisture decreases due to external pressure, the moisture absorbed by the sponge is easily removed. In addition, after the volume of the sponge is reduced by the external pressure, when the external pressure is removed, the sponge is restored to its original volume due to the elastic force of the sponge. Based on the elasticity of the sponge, the cleansing pad 200 may maintain its shape.

According to an embodiment, the cleansing pad 200 may include an upper pad 20, a middle pad 40, and a lower pad 60 that are mutually coupled through an adhesive. However, chemical components contained in the adhesive may cause unpleasant odors and skin problems.

According to an embodiment, the cleansing pad 200 may include an upper pad 20, a middle pad 40, and a lower pad 60 that are mutually coupled through sewing. Since sewing is performed by a person, the length of the sewing line formed by sewing or the line to which the sewing line is connected may not be constant. Such a sewing line may reduce the aesthetics of the cleansing pad 200.

3 illustrates a cleansing pad 300 according to an embodiment.

Referring to FIG. 3, the cleansing pad 300 may further include an edge 80. The edge 80 is a portion disposed along the side surface of the cleansing pad 300 (a curved surface surrounding the side of the cleansing pad 300), and the edge 80 can cover the sewing line of the cleansing pad 300. , The aesthetics of the cleansing pad 300 may be improved.

However, the edge 80 may be an obstacle in utilizing the edge portion of the cleansing pad 300. Specifically, in order to remove foreign substances such as cosmetics from a narrow or curved portion of the face (for example, between the nose and cheekbones), the edge portion of the cleansing pad 300 needs to directly contact the foreign substances, By covering the edge portion of the cleansing pad 300 by the edge 80, it is possible to prevent the edge portion from contacting foreign substances.

4 illustrates a cleansing pad 400 according to an embodiment.

Referring to FIG. 4, the upper pad, the middle pad, and the lower pad of the cleansing pad 400 may be coupled to each other without adhesives or sewing lines.

According to an embodiment, since the cleansing pad 400 does not include an adhesive for bonding the upper pad, the middle pad, and the lower pad to each other, an unpleasant odor and skin trouble due to the adhesive do not occur. In addition, since the cleansing pad 400 does not include a sewing line and an edge for covering the sewing line, an edge portion of the cleansing pad 400 may be usefully used.

According to an embodiment, the upper pad, the middle pad, and the lower pad are coupled to each other by ultrasonic fusion, so that the cleansing pad 400 may not include a sewing line that may be formed due to sewing and/or an edge for covering the sewing line. . The mutual bonding by ultrasonic fusion will be described in detail in the method of manufacturing a cleansing pad.

Referring to Figure 5, the manufacturing method of the cleansing pad 200, the first step of preparing an upper pad 20 including a first fabric, a lower pad 60 including a second fabric, and the middle pad 40 (S5200) may be included.

The first fabric or the second fabric may be obtained by dyeing a knitted fabric in which warp and weft yarns cross one by one, and then coating to soften the fabric.

Microfiber fibers 10 formed by pulling long piles included in the first fabric may be disposed on the upper surface of the upper pad 20, and microfiber fibers 10 formed by pulling long files included in the second fabric are lower pads It can be disposed on the lower surface of the 60.

The manufacturing method of the cleansing pad 200 may include a second step (S5400) of disposing the middle pad between the upper pad and the lower pad. The middle pad 40 may include an elastic body made of a porous material such as a sponge.

The manufacturing method of the cleansing pad 200 may include a third step (S5600) of combining the upper pad 20, the middle pad 40, and the lower pad 60 in a predetermined frequency region through ultrasonic fusion.

Through ultrasonic fusion in a predetermined frequency range, the bonding surface of the upper pad 20 and the middle pad 40 and the bonding surface of the middle pad 40 and the lower pad 60 may be heated and melted. Specifically, in a predetermined frequency range, fine protrusions on each surface of the upper pad 20, the middle pad 40, and the lower pad 60 heat up very quickly by ultrasonic vibration, a thin molten layer is formed, and a thin molten layer As it is hardened, the upper pad 20, the middle pad 40, and the lower pad 60 may be coupled to each other.

In addition, the predetermined frequency range may vary depending on the thickness and material of the upper pad 20, the middle pad 40, and the lower pad 60.

Referring to FIG. 6, the cleansing pad 200 may be manufactured through an automated system including a conveyor belt and an ultrasonic welding and cutting machine.

A person or machine may place the lower pad 60 on the conveyor belt, the middle pad 40 on the lower pad 60, and the upper pad 20 on the middle pad 40. The disposed lower pad 60, the middle pad 40, and the upper pad 20 may be ultrasonically fused on a conveyor belt and moved under a cutting machine.

The ultrasonic welding and cutting machine can sharpen the ultrasonic output unit to perform ultrasonic welding and ultrasonic cutting at the same time. Specifically, the ultrasonic welding and cutting machine combines the upper pad 20, the middle pad 40, and the lower pad 60, and at the same time, the edges of the upper pad 20, the middle pad 40, and the lower pad 60 It can be ultrasonically cut (Cutting).

The method of manufacturing the cleansing pad 200 using ultrasonic welding and cutting machine is a bar that can produce the cleansing pad 200 in a short time that is incomparable to the method of using an adhesive or sewing, cleansing pad 200 Productivity is improved and production costs are reduced.

Hereinafter, in terms of production cost and productivity of the cleansing pad 200, the advantages of using an ultrasonic welding and cutting machine will be described in detail over using a sewing method.
