Description

Mask

The present invention relates to a close-fitting mask, and more particularly, to a mask that is completely in close contact with the user's face by elasticity and covers the entire face to prevent exposure of the cheek area and leave no trace of wearing the mask.

With the recent outbreak of novel influenza (swine flu) and corona viruses (SARS, MERS, COVID-19, etc.) around the world, various analyzes and forecasts of the disease, rate of spread, and aftermath are pouring in, and countries around the world are taking preventive measures. are anxious about

In particular, according to the World Health Organization (WHO), swine flu and coronavirus are transmitted from person to person, and it is reported that there is a high possibility of droplet infection, which is mainly transmitted through droplets spread in the air through coughing or sneezing. Therefore, the importance of quarantine against virus particles present in the atmosphere of the space where many people work or live is increasing day by day.

As the situation of coronavirus infection-19 (COVID-19) prolongs, hand washing and wearing a mask are emphasized to prevent virus infection, and public places where the public gathers, riding on subways, buses, etc. Wearing a mask is becoming a necessity in outdoor activities such as workplaces.

In addition, high-performance filter masks that can block viruses and filter fine dust of KF80, KF94, and KF99 grades are being sold in Korea. These high-performance masks filter in such a way that small pores, which are difficult for viruses and fine dust to pass through, filter out viruses and fine dust and allow air to pass through.

The mask for this purpose has enhanced facial adhesion to prevent viruses or fine dust from entering the gap between the face and the mask. In order to increase the facial adhesion of the mask, a method of attaching a thin metal piece deformed according to facial curvature to the bridge of the nose and pulling it to the head using a strong elastic band is used.

An example of such a technique is disclosed in Patent Documents 1 to 3 and the like.

For example, in Republic of Korea Patent Publication No. 10-2094480 (registered on March 23, 2020, Patent Document 1), as shown in FIG. 1, the center protrudes according to the contour of the face, and the mask part ( 10), a ring portion 11 formed on both ends of the mask portion 10 to allow the mask to be hung over the ear, a sealing member fixed to the inner surface of the mask portion 10, and between the inner surface of the mask portion 10 and the face It includes a fine dust filter paper positioned in the, wherein the fine dust filter paper is partially fixed to the inner surface and/or sealing member of the mask, the non-fixed part moves according to breathing, and the mask unit 10 is a non-antibacterial upper knitted fabric, Disclosed is a fine dust mask, which is a triple-woven antibacterial mask part made of a lower knitted fabric including a fiber containing a copper component and a vertical knitted fabric including a monofilament yarn fiber.

In addition, as shown in FIG. 2, in the Republic of Korea Patent Publication No. 10-2070193 (registered on January 20, 2020, Patent Document 2), the mask body 20 and the connecting ring 30 are formed, and the mask body 20 consists of a filter pad 21 for filtering fine dust and a binding part 22 fixed to the edge of the filter pad, and the filter pad 21 is made of fiber material to filter dust or fine dust contained in yellow sand. The binding part 22 is attached or sewn and fixed while enclosing the edge of the filter pad 21, and eucalyptus oil is sprayed onto the filter pad 21 of the mask body 20 after filling the atomizer. It is disclosed for a yellow dust mask formed as a coating layer by coating.

On the other hand, Republic of Korea Utility Model Publication No. 20-0492402 (registration of September 25, 2020, Patent Document 3) has an air mesh fabric as a material, an air mesh mask pad formed to fit the user's face shape, the air mesh The mask string formed on both sides of the mask pad and worn by the user on both ears, is disposed on one side of the air mesh mask pad facing the user's face, and the upper and lower ends of the air mesh mask pad have upper and lower sides and Disclosed is a function-variable mask including a mask endothelium to be bonded and a filter inserted between the air mesh mask pad and the mask endothelium to filter fine dust according to the user's breathing.

In the technology disclosed in Patent Document 1 as described above, the mask part consists of a triple-woven antibacterial mask made of a non-antibacterial upper knitted fabric, a lower knitted fabric including a fiber containing a copper component, and a vertical knitted fabric including a monofilament yarn fiber, There was a problem that the manufacturing cost of the mask increases, the mask part is not in close contact with the user's face part, so it is impossible to prevent inhalation of fine dust, etc., and droplets due to the user's breathing or coughing may be spread to the outside.

In addition, in the technique disclosed in Patent Document 2, since the mask body is composed of a filter pad and a binding portion fixed to the edge of the filter pad, the manufacturing process is complicated, manufacturing cost increases, and use is complicated. In the technology, since the mask lining and the filter are provided on the mask pad, the manufacturing cost increases, and if breathing is increased due to exercise or the like due to poor ventilation, the problem of breathing difficulties may occur.

On the other hand, as the situation of coronavirus infection-19 (COVID-19) prolongs, wearing a mask indoors and outdoors is compulsory, and as the weather gets hotter, wear a KF80, KF94, KF99 grade mask that has poor ventilation in outdoor activities This may cause problems with breathing. For this reason, when wearing a dental mask that is easier to breathe and cool compared to a KF certified mask for health use, there is a problem of lowering of facial adhesion.

That is, in the case of a dental mask, although it has a structure in which a metal material is inserted in the upper part for sealing, it is partially open from both sides of the nose part, and the cheek part of the face is also exposed, so there is a problem that splashes occur.

In addition, after wearing the mask, there was a problem of leaving marks on the face due to the mask wearing line (connection for earrings) pulled for close contact with the face. In addition, in the case of the mask as disclosed in Patent Documents 1 and 2 described above, the space between the mask body and the connecting ring is a space part, and there is a problem that the skin cannot be protected by exposure to sunlight (ultraviolet rays) or the like when used outdoors for a long period of time.

On the other hand, when the wearer of the glasses wears the mask as described above, the ventilation is not good, the glasses are fogged and the field of view is blocked, and there is a problem that the connection ring of the mask is caught on the glasses frame.

It is an object of the present invention to provide a mask that has been made to solve the above-described problems, is ventilated so that there is no breathing difficulty due to wearing the mask, and can be completely in close contact with the user's face by elasticity.

Another object of the present invention is to provide a mask that can prevent exposure of the cheek area by covering the entire face when the mask is worn.

Another object of the present invention is to provide a mask that is excellent in wearing comfort when wearing the mask, and does not leave any traces of wearing the mask.
