The present invention relates to a sanitary mask that blocks fine dust or yellow dust, and in particular, a lineless mask that is fixed to the chin and nose without a line or strap to secure the mask to the user's face. ) It's about masks.

In general, a mask is known as an item that covers the nose and mouth to prevent inhalation and scattering of germs, dust, etc. for health and hygiene reasons. These masks are used in various structures and shapes depending on the purpose of use, and can be broadly divided into sanitary masks and dust masks.

As people's awareness of hygiene increases, sanitary masks are used in group cafeterias, restaurants, other places where various types of food are handled, hospitals, department stores, etc., to prevent saliva or other foreign substances from workers' mouths from splashing onto others. It is being used for.

In addition, the environmental atmosphere contains a large amount of foreign substances such as fine dust, and in order to prevent various respiratory diseases, asthma, headaches, atopy, etc. caused by fine dust and yellow dust, wearing a dust mask is recommended when the concentration is high.

Most of these sanitary masks or dust masks are made of transparent or translucent synthetic resin material to prevent saliva or other foreign substances from the wearer's mouth from splashing, and include filters to prevent fine dust or bacteria from outside. , it is designed to prevent viruses, etc. from getting on or being inhaled by the wearer.

Patent Document 1 (Korean Patent Publication No. 10-1627973) discloses a main body 11 covering the user's facial area as shown in FIG. 1, a blocking film 14 added to the front of the main body 11 and open at both left and right ends, and A multi-purpose mask (10) is provided with an outer filter (13) and an inner filter to remove yellow dust and fine dust, and includes a fixing string (12) that fastens the main body (11) to the user's ears.

However, in the above-mentioned patent document 1, the mask body 11 included a string 12 that is fixed to the ears or the back of the head, and the length of the string 12 had to be adjusted according to the size of the wearer's face, causing inconvenience in its use. There was a problem in that the straps 12 became loose shortly after wearing, deteriorating the blocking function of the mask. In addition, masks with strings (12) attached not only cause pain when the strings are pulled or tightened, but also do not easily adhere to the wearer's face even when the mask is worn, allowing harmful external substances to enter the body through the nose or mouth. There was a high possibility of inflow.

In order to improve this problem, Patent Document 2 (Korean Patent Publication No. 10-1569139) discloses an adhesive dust mask that adheres to the skin without a separate fixing means to avoid discomfort during work. Referring to FIG. 2, the adhesive dust mask 20 of Patent Document 2 has an attachment band on the edge of the inner fabric of the body portion 21 so that it can be used in close contact with the skin without using a string like in Patent Document 1. (22) is used. The attachment band 22 uses a form that provides appropriate adhesiveness to the general hydrogel form widely used in wound dressings, medical bands, etc. so that it adheres closely to the skin and minimizes irritation even with continuous use.

However, when the adhesive dust mask of Patent Document 2 is used for a long period of time, the adhesive strength of the attachment band decreases, so it cannot be completely adhered to the face, and gaps may open, which may significantly reduce the function of the mask. In addition, the attachment band 22 has the problem of causing skin problems in some wearers even if the material is an eco-friendly material.

Figure 3 is a perspective view of a lineless mask according to an embodiment of the present invention, Figure 4 is a perspective view when the nose fixing member of the lineless mask of Figure 3 is opened, and Figure 5 is an embodiment of the present invention. This is a vertical cross-sectional view of a lineless mask according to an example. Referring to Figures 3 to 5, the lineless mask according to an embodiment of the present invention does not have a fixing string for attaching and fixing the mask 300 to the face. The lineless mask of the present invention includes a mask body 310, a glasses nose ring seating portion 320, and a chin fixing portion 330 extending from the mask body 310.

The mask body 310 forms the appearance of the lineless mask 300 according to this embodiment. The mask body 310 is made of soft polyurethane or a corresponding material that can be gently adhered to the face. The mask body 310 has a structure that protrudes convexly forward, as shown in FIGS. 3 to 5 . Therefore, it covers the area around the mouth and nose of the face.

A pair of the spectacle nose ring seating portions 320 is formed on the outer surface of the upper portion of the mask body 310 that is in close contact with the nose. The glasses nose ring of the wearer wearing the mask 300 is seated on the glasses nose ring seating portion 320. Each pair of nose rings of glasses is seated on each of the pair of glasses nose ring seating portions 320. Therefore, the part of the mask body 310 that is in close contact with the nose is naturally fixed to the nose by the wearer's glasses.

The nose ring seating portion 320 of the glasses is made of a silicone material or a thermoplastic elastomer (TPE: Thermo Plastic Elastomer) and has a predetermined anti-slip pattern formed on its surface to prevent the nose ring of the glasses from slipping when it is seated. Here, the anti-slip pattern may have a dot, stripe, grid, or a combination thereof, and the stripes may have a straight line, a curve, or a combination thereof. Since the face size and nose size of the mask wearer vary, it is preferable that each glasses nose ring seating portion 320 has an oval shape with a width of 1 cm in the horizontal direction of the face and a length of at least 2 cm in the longitudinal direction of the face.

The chin fixing part 330 extends from the lower part of the mask body 310, surrounds the chin of the wearer wearing the mask 300, and is fixed to the chin. The chin fixing part 330 may be formed integrally with the mask body 310 using soft polyurethane or a corresponding material. As shown in FIG. 5 , the chin fixing part 330 extends from the lower end of the mask body 310 to form the mask body 310 and the concave portion 331. The wearer's chin is inserted into the concave portion 331 and fixed to the wearer's chin. Preferably, the inner angle θ of the concave portion 331 is 90 degrees or less when the wearer is not wearing the mask 300, that is, when the wearer's chin is not inserted into the concave portion 331. More preferably, it is 45 degrees or less. Therefore, when the wearer wears the mask 300 on the face, as shown in FIG. 4, the chin fixing part 330 opens and the concave part 331 surrounds the wearer's chin to exert appropriate pressure on the chin. It can be fixed without being pushed up onto the face.

The mask body 310 and the chin fixing part 330 may be integrally formed of soft polyurethane or a material equivalent thereto. Soft polyurethane or equivalent materials can be washed and used repeatedly, and due to their unique elasticity, they adhere well to the wearer's face without a fixing strap, providing excellent wearing comfort and minimizing the gap between the mask body 310 and the face. can do. In another embodiment, the mask body 310 may be made of soft polyurethane or a corresponding material, and the chin fixing part 330 may be made of a stretchable silicone material. Alternatively, the mask body 310 and the chin fixing part 330 may be integrally formed of soft polyurethane or a corresponding material, and a concave-shaped elastic silicone member may be attached to the inside of the chin fixing part 330. .

Figure 6 is a side view showing a lineless mask worn on the face according to one embodiment, and Figure 7 is a front view showing a lineless mask worn on the face according to another embodiment. Referring to FIGS. 6 and 7 , the wearer wearing glasses 600 first inserts the wearer's chin into the concave portion 331 formed in the chin fixing portion 330 of the lineless mask 300 from below the chin. Move the chin fixing unit 330 to the chin area. Accordingly, the wearer's chin is inserted into the concave portion 331 formed in the chin fixing portion 330. Then, the wearer lifts the mask body 310 in the direction of the nose, covers the nose, and then places the nose pad 610 of the glasses 600 on the glasses nose pad seating portion 320 formed on the surface of the mask body 310. When the mask 300 is worn in this way, pressure is applied in the A direction due to the elastic force of the chin fixing part 330, so that the chin fixing part 330 is closely fixed to the wearer's chin, and the weight of the glasses 600 causes the mask 300 to be worn. The nose portion of the mask body 310 is deformed to fit the shape of the wearer's nose by applying force in the B direction and is fixed in close contact with the wearer's nose.

As described above, the wearer of the mask 300 according to this embodiment wears glasses 600 and uses the nose bridge 610 of the glasses 600 as a fixing means for the mask 300. Even if the mask 300 is pressed with the nose ring 610 of the glasses 600, a gap may form between the mask 300 and the facial skin, and breath may leak through the gap, causing fogging of the glasses 600. . Therefore, a method to prevent such fogging is needed, and an anti-fogging pad may be installed on the part of the mask 300 according to this embodiment that is in close contact with the nose.

Figure 8 is a diagram showing an anti-fog pad of a lineless mask according to an embodiment. Figure 8 is a cross-sectional view of the mask body 310 when looking at the nose from the head of the face. As shown in Figure 8, the mask body 310 has an anti-fog pad 810 on the part that is in close contact with the nose. ) is installed. The anti-fog pad 810 may be made of silicone material. The anti-fog pad 810 is in close contact with the face across the nose and prevents the breath coming from the mouth or nose from flowing toward the glasses 600, thus preventing the glasses 600 from fogging. Since the sizes of people's faces and noses vary, the width of the anti-fog pad 810 along the length of the face is 1 cm, the length across the nose is at least 4 cm, and the thickness can be constant. In another embodiment, the part of the anti-fog pad 810 that is in close contact with the bones on both sides of the bridge of the nose may be thicker than other parts to sufficiently seal the bones on both sides of the bridge of the nose.

The lineless mask 300 described in the above embodiment does not use a fixing strap or adhesive as in the prior art to fix the mask body 310 to the wearer's face, but a chin fixing part extending from the mask body 310 ( 330) and the nose ring 610 of the wearer's glasses 600 are used. Therefore, it is possible to eliminate the pain caused by the strings while wearing a conventional mask and improve the wearing comfort. In addition, the lineless mask 300 described in the embodiment prevents the glasses 600 from fogging, which may occur when the wearer's glasses 600 are used as a fixing means, with an anti-fogging pad 810. In addition, since the mask 300 is made entirely of soft polyurethane or a corresponding material that can be adhered to the face, it is not easy to adhere to the wearer's face even when wearing a conventional mask, so harmful external substances are released. This can reduce the possibility of it entering the human body through the nose or mouth.

Although the present invention has been described above with limited examples and drawings, the present invention is not limited thereto, and the technical idea of the present invention and the description below will be understood by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalence of the patent claims.
