Description

Dental mask with 3D mask function}

The present invention relates to a mask, and more specifically, to fuse the folded ends of a plurality of wrinkles formed on the mask body of a dental mask along the longitudinal direction, so that when the mask is worn, the fused portion has a round shape and serves as a support. This relates to a dental mask with a 3D mask function that forms the same dome shape as when wearing a 3D mask.

In general, a mask is something that covers the nose and mouth to block cold outside air and prevent the inhalation and scattering of germs, dust, etc. It can range from cold weather masks made of fabric, etc. to fine dust by combining various filters. Various types of products, including industrial and dust masks, are sold depending on their purpose. Following SARS and MERS, the World Health Organization (WHO) recently declared a global pandemic due to the spread of coronavirus disease 19 (COVID-19). As interest in masks has increased and wearing masks has become routine, masks have become a necessity when going out.

A mask is effective when worn normally so that it covers both the nose and mouth. However, some people wear it with their nose uncovered because it is stuffy when it covers both the nose and mouth, or wear it only over the chin without covering both the nose and mouth. . In particular, recently, due to the spread of COVID-19, the government has implemented administrative measures mandating the wearing of masks when going out. However, there are frequent cases of fights breaking out due to people not wearing masks normally in multi-use facilities, public transportation, or public places. However, the most common problem when wearing a mask is that even if the mask is worn normally, when talking or yawning, the mask falls down and goes beyond the bridge of the nose, preventing it from covering the nose. So, while talking, you have to hold the upper part of the mask body with your hand and pull it up. You repeat the motion of covering your nose with the mask, and the exhaled air you exhale while breathing causes your glasses to fog up, causing the inconvenience of having to take off your glasses in severe cases.

To solve this problem, Patent Registration No. 1418787, “A mask that is easy to wear and prevents slipping off,” and Patent Registration No. 1651728, “A mask with tightening means,” have appeared. However, these have ear bands that cover the head. There is a problem that it is difficult to apply it to disposable health masks or dental masks where wearing a mask is mandatory.

In addition, the applicant of the present invention has been in the mask business for a long time and has developed and patented various masks. For example, Patent Registration No. 2012157 "Tight-fitting mask with elastic band" has a nose pad on the inside of the mask body. It is attached, has an elastic and elastic adhesion part on the edge, and an elastic band is installed across the entire upper part of the mask body to ensure that the mask adheres well to the face part. The above patent has excellent adhesion between the mask and the face due to the many configurations such as the nose pad, adhesive part, and elastic band on the inside of the mask body, so the effect of preventing yellow dust, fine dust, or various viruses from penetrating into the respiratory tract is excellent, but the structure is too small. Because it is complex and expensive, there is a problem that it is difficult to apply to disposable health masks or dental masks, which are currently mandatory.

Recently, with the wearing of masks becoming mandatory due to COVID-19, it is common to wear health masks KF80, KF94 or dental masks. Since KF80 and KF94 are in the form of 2D or 3D masks, the mask body forms a dome when worn due to the mask structure. Although forming a shape prevents the phenomenon of dripping or fogging of glasses to some extent, due to the structure of the dental mask, the mask body cannot form a dome shape when worn, so the mask body sticks to the lips, causing severe dripping and fogging. This occurs because both sides of the rectangular mask main body are worn in a lifted state on the wearer's cheeks, so even when the mask is worn, spaces are created on both sides, allowing viruses and various bacteria to penetrate through the spaces formed on both sides, as well as yellow dust and dust. There is a problem with fine dust flowing in.

The present invention was devised to solve the above problems, and the purpose of the present invention is to fuse the folded ends of the plurality of wrinkles formed on the mask body of the dental mask along the longitudinal direction so that when the mask is worn, the fused portion The purpose is to provide a dental mask with a 3D mask function that has a round shape and serves as a support, forming a dome shape similar to when wearing a 3D mask.

Another object of the present invention is to form a nose support that supports the bridge of the nose and a chin rest that supports the chin when wearing a mask, respectively, at the upper and lower parts of the inside of the mask body, so that the mask can be worn even when speaking while wearing the mask. The purpose is to provide a dental mask with a 3D mask function that does not fall off, prevents glasses from fogging, and allows both sides of the mask body to be in close contact with the wearer's cheeks.

The dental mask with a 3D mask function according to the present invention has a rectangular mask body that covers the wearer's mouth and nose and has a nose wire of a certain length embedded in the left and right directions at the top, and a mask body on both sides of the mask body, respectively. It is composed of an ear band to prevent the mask body from leaving the face when attached and worn. The mask body has 2 to 3 lines of wrinkles formed in the left and right directions in the up and down directions, and each wrinkle is folded on the outside. The parts are fused along the longitudinal direction to form a fused area of a certain width, and the fused area, which becomes stiffer than other parts as it is fused, acts as a support, so that when the mask is worn, the wrinkles are not distorted and the mask body forms a dome shape. It is characterized by being able to do it.

Preferably, a nose support is further formed on the inside of the mask main body at the bottom of the part where the nose wire is embedded in the mask main body, and the nose support is square-shaped, both sides of the square shape are fused to the mask main body, and the lower side is open ( It is attached and installed in an open position, and the vertical height of the nose support is ½ to ⅓ of the vertical height of the mask body.

Preferably, a chin rest is further formed on the inner lower part of the mask body, the chin rest is square-shaped, both sides of the square shape are fused to the mask body and attached and installed with the upper side open, and the chin rest is The vertical height of is 1/3 to 1/5 of the vertical height of the mask body.

Preferably, in the square shape of the nose support, the central portion of the lower side is cut for a certain length in the vertical direction from the bottom, and the lower edge portions are formed to be inclined on both sides of the nose support.

Preferably, the mask body is further formed with a color-changing display portion that changes color depending on the wearer's body temperature by punching the mask body, and the color-changing display portion is formed on either side of the mask body and is located between the nose support and the chin rest. It is installed to be positioned or installed on the chin rest.

In the dental mask according to the present invention, the folded ends of the plurality of (two or three) wrinkles formed on the mask body are fused along the longitudinal direction, so when the mask is worn, the fused portion is not distorted and forms a round shape. It acts as a support and forms a dome shape similar to when wearing a 3D or 2D mask, so the mask body does not stick to the lips.

In addition, a nose support and a chin rest are formed on the upper and lower inner sides of the mask body, respectively. The nose support and a chin rest are structured in such a way that three sides, including both sides, are fused (or blocked) with the mask body, leaving only one side open. Because the nose wire is not inserted into the zone, when the mask is worn, the nose support naturally hangs over the bridge of the nose to support it, preventing the mask from falling down even when speaking while wearing the mask, preventing the glasses from fogging up. .

In addition, since both sides of the nose support and chin rest are fused to the mask body, when the mask is worn and the ear bands are placed over the ears, the top and bottom of the sides of the rectangular mask body are pulled laterally by the ear bands. , The nose support and chin rest are placed over the bridge of the nose and chin, respectively, and pull the side of the mask body inward, so that the space between the nose support and chin rest is not lifted and is in close contact with the wearer's cheek. Therefore, it completely solves the problem of both sides of the mask body lifting off the wearer's cheeks when wearing a regular dental mask.

In addition, since the dental mask is structured to have a discoloration indicator that changes color depending on the wearer's body temperature on the area exposed to the outside when worn, if the mask wearer's body temperature is higher than normal due to infection with a virus or influenza, the discoloration indicator changes color ( Since the mask wearer has a fever, it is possible to naturally restrict access to multi-use facilities, public transportation, or public places, as well as prevent third parties from coming into contact with an infected person. It can greatly contribute to preventing the spread of infectious diseases because it allows you to avoid contact with or close to it in advance.

The technical features of the dental mask according to the present invention are that the folded ends of the plurality of wrinkles formed on the mask main body are fused along the longitudinal direction so that the mask main body forms a dome shape when the mask is worn, and the inside of the mask main body By forming a nose support and a chin rest at the top and bottom, respectively, the mask does not fall off, prevents glasses from fogging up, and ensures that both sides of the mask body are in close contact with the wearer's cheeks.

The dental mask with a 3D mask function according to the present invention includes a dental mask in which the mask body is formed in a rectangular shape, a surgical mask mainly used by medical personnel such as doctors and nurses, and a KF-AD mask, which is a droplet blocking mask. Applies. Therefore, it should be noted in advance that the term 'dental mask' in the specification of the present invention includes not only dental masks but also surgical masks and KF-AD masks.

The dental mask 10 includes a rectangular mask body 11 that covers the wearer's mouth and nose, and is attached to both sides of the mask body 11 to prevent the mask body from leaving the face when worn. It is composed of an ear band (16), and has a rectangular shape, in the central part of the upper part, a nose wire (13), which is folded into the shape of the bridge of the nose when worn, is embedded at a certain length, and the mask body (11) is made of outer material. It is manufactured by inserting a filter between the mask and the lining and fusing it along the edges of the rectangular shape. The mask body (11) has a two- or three-stage mask body (11) that spreads according to the shape of the face when worn to expand the area. The general structure of a dental mask is that the wrinkle part 12 is formed by folding ).

One of the technical features of the dental mask 10 according to the present invention is that the mask body 11 forms a dome shape when applied. The component for forming the dome shape is the fusion portion 121 formed on the wrinkle portion 12. The wrinkles 12 are formed by folding the mask body 11 and fusing the folded ends on the outside. The wrinkles 12 formed in the left and right directions are formed in 2 to 3 rows at regular intervals in the up and down directions, and are formed at regular intervals in the mask body 11. When worn, the wrinkles 12 unfold and the area expands to cover the face. Since the dental mask is structurally unable to form a dome shape when the wrinkles 12 are unfolded, the mask body 11 There is a problem that it is uncomfortable because it adheres closely to the wearer's face and lips.

However, the dental mask 10 of the present invention is fused with the ends folded on the outside of each pleated portion 121 along the longitudinal direction (here, 'fused' is meant to join the two members, so it also includes joining them by sewing). ) to form the fused portion 121. The fused portion 121, which is formed by fusion of the outer fabric and lining that make up the mask body 11 and the filter inserted between them, is stiffer than other parts, so when the mask is worn, the pleated portion 121 is not distorted and has a round shape. Since the mask body 11 forms a dome shape while acting as a support, the mask body 11 does not stick to the face and lips (see Figure 4).

One of the technical features of the dental mask 10 according to the present invention is that a nose support 14 is formed on the inner upper part of the mask body 11. At the bottom of the part where the nose wire 13 is embedded in the mask body, a nose support 14 is further formed on the inside of the mask body. The nose support 14 is manufactured in a square shape such as a rectangle or trapezoid, and has a square shape. Both sides are fused to the mask body 11, and are attached and installed with the mask body 11 open downward. The nose support 14 can be formed by folding a certain part of the mask body 11 when manufacturing the mask, or by attaching a separate member to the mask body 11 and fusing both sides and the top to the mask body 11. You may.

Since the lower part of the nose support 14 is not fused to the mask body 11 but is separated and opened downward, when wearing the mask, the nose wire 13 is folded into the shape of the bridge of the nose and the lower part of the nose support 14 is closed. When separated from the mask body 11, a space is formed between the nose support 14 and the inner surface of the mask main body 11, so the dental mask (14) is placed on the bridge of the nose with the nose support 14 in the space where the space is formed. 10) Wear it. For the convenience of wearing the mask, it is preferable that the lower corners of both sides of the nose support 14 be inclined diagonally (see FIGS. 2A and 2B).

Since the nose support 14 is located in the lower part of the mask body 11 where the nose wire 13 is embedded, the nose support 14 can naturally adhere to the bridge of the nose without interference from the nose wire 13. There will be. In addition, since both sides of the nose support 14 are fused to the mask body 11, both sides of the nose support 14 serve to prevent the nose support 14 from falling down. In addition, since the top of the nose support (14) is fused to the lower part than the nose wire (13), even if you hold the mask body (11) with your hand and pull it downward, only the mask body (11) moves down slightly and the nose support is (14) can be maintained in close contact with the bridge of the nose.

If the nose support (14) is fused to the upper part of the mask body (11) where the nose wire (13) is embedded, not only will the adhesion of the nose support (14) to the bridge of the nose be weakened when the mask is worn, but the nose wire will also be damaged. (13) cannot contact the bridge of the nose, and the nose support (14) swells at the top of the mask body (11), which makes wearing the mask uncomfortable because it does not look good and may interfere with vision.

Since the nose wire is not embedded in the nose support (14), it is made of a non-woven filter, etc., so that the flexible nose support (14) can naturally adhere to the bridge of the nose, completely blocking the gap in the curved area around the bridge of the nose. It not only blocks the penetration of viruses through the mouth, but also prevents the phenomenon of fogging of glasses caused by exhaled breath while talking or breathing while wearing the dental mask of the present invention.

It is most preferable that the vertical height of the nose support 14 is about ½ to ⅓ of the vertical height of the mask body 11. If the vertical height of the nose support 14 is made larger than ½ of the vertical height of the mask body 11, the mask cannot be worn properly, and if it is made smaller than ⅓, the nose support 14 can be used when having a conversation. There is a high possibility that the mask body 11 will slip off the bridge of the nose.

The nose support 14 has the same structure as the mask body 11 (a structure with a filter inserted between the outer material and the lining) or is made of a material such as a non-woven filter, polypropylene (PP), or polyethylene (PE) and is formed in two layers. desirable. It must be formed in two layers so that the nose support (14) has a stronger adhesion to the bridge of the nose, which not only strengthens the force that holds the mask body (11) from leaving the bridge of the nose, but also prevents fogging by blocking the gap in the curved area around the bridge of the nose. Functionality can be improved.

In the square shape of the nose support 14, it is desirable to form an incision 141 in the center of the lower side by cutting a certain length in the vertical direction from the bottom. When the incision 141 is formed, both sides of the incision are made. Because it completely closes the gap in the curved area around the bridge of the nose, it can more effectively prevent the fogging of glasses. The cut shape of the cut portion 141 may be formed in various shapes such as triangles and arcs, or may be formed by simply cutting in the vertical direction (see Figure 2b).

A chin rest 15 may be further formed on the inner lower part of the mask body 11. The chin rest 15 has a square shape, both sides of the square shape are fused to the mask body 11, and the upper part has an opening. It is attached and installed in an open state. The chin rest 15 can be formed by folding a certain portion of the mask body 11 when manufacturing the mask, or by attaching a separate member to the mask body 11 and fusing both sides and the bottom to the mask body 11. You may. It is desirable that the vertical height of the chin rest 15 is approximately 1/3 to 1/5 the vertical height of the mask body 11. Since the nose support 14 and the chin rest 15 are installed inside the mask body 11, the dental mask 10 according to the present invention has a structure similar to a 3D mask and can function as a 3D or 2D mask. It becomes possible.

When the mask is worn and the ear band 16 is placed on the ear, the top and bottom sides of the rectangular mask body 11 are pulled laterally by the ear band 16, and the nose support 14 and chin rest Since both sides of (15) are fused to the mask body (11), the nose support (14) and chin rest (15) are placed on the bridge of the nose and chin, respectively, pulling the sides of the mask body (11) inward. The side of the mask main body located between the nose support 14 and the chin rest 15 is in close contact with the wearer's cheek without lifting. Therefore, when wearing a regular dental mask, the side of the mask body is lifted from the wearer's cheek, forming a space, completely solving the problem of dental masks being vulnerable to bacteria or viruses penetrating through the lifted space.

One of the other technical features of the present invention is that the mask body 11 is provided with a discoloration display unit 20 that changes color when the wearer has fever symptoms above a certain temperature depending on the body temperature of the wearer. Since the discoloration display unit 20 changes color according to the wearer's body temperature, it can be easily visually recognized by others. When wearing the dental mask 10 of the present invention, the wearer can see the thermometer that measures the wearer's body temperature. Although it cannot be done, it can have the same effect as letting others know if you have a fever by attaching it to your face so that others can see it. Therefore, even if the mask wearer has no other symptoms, if he or she has a fever, it is possible to naturally restrict access to multi-use facilities, public transportation, or public places, as well as to prevent third parties from contacting or being close to an infected person in advance. Therefore, it can greatly contribute to preventing the spread of infectious diseases.

The discoloration display unit 20 is made of non-woven fabric made of synthetic resin materials such as polypropylene (PP), polyethylene (PE), polystyrene (PS), acrylonitrile butadiene styrene (ABS), etc., in the form of a film, or silicone, hydrogel, neoprene. It is manufactured by mixing Zion pigment, colorants, and additives in a predetermined ratio with materials such as synthetic resin, silicone, hydrogel, and neoprene, and then molding them, or coating the surface with a material that combines Zion pigment, colorants, and additives. The color changes starting from a certain temperature, making it possible to easily identify whether the mask wearer has fever symptoms by looking at the discolored state. Since the Zion pigment is not a characteristic composition or material unique to the present invention, but is a material that has already been developed and is commercially available, a detailed description of the composition or composition of the Zion pigment will be omitted.

The discoloration display unit 20 is formed by punching a certain portion of the mask body 11 and forming a hole, and then attaching the discoloration display unit 20 to the punched portion using a method such as heat fusion. Not only must it be formed on the part that comes into contact with the wearer's body, but it must also be formed on the exposed part so that other people can see it clearly, so when the mask is worn, the mask body (11) touches the chin, the part that touches the cheek, It can be formed in various places, such as the part that touches the bottom of the ear or the part where the breath comes out, and since this is a matter of simple selection of the position where the color change display unit 20 is attached, it can be changed without any technical difficulty. For example, the discoloration display unit 20 may be formed on either side of the mask body 11 and installed between the nose support 14 and the chin rest 15, or may be installed on the chin rest 15. It can also be installed on the ear band (16).

It is desirable that the discoloration display unit 20 has different colors depending on when the mask is not worn, when the wearer's body temperature is normal, or when the wearer's body temperature is above a certain level. For example, brown when not wearing a mask, blue or light green when the wearer's body temperature is normal (35-37.5℃) while wearing a mask, and blue or light green when the wearer's body temperature is normal (35-37.5℃) while wearing a mask. At high temperatures (above 37.5℃), the color can change to red, etc., and the color can be determined by adjusting it as much as necessary to visually distinguish it. Since the Zion pigment is reversible, if you wear the mask and then take it off, it will remain unworn. It returns to its color.

The above description is an illustrative description of the present invention, and the embodiments published in the specification are not intended to limit the technical idea of the present invention, but are for illustrative purposes, so those skilled in the art Various modifications and variations will be possible without departing from the technical idea of . Therefore, the scope of protection of the present invention should be interpreted based on the matters stated in the claims, and technical matters within the equivalent scope thereof should also be interpreted as being included in the scope of rights of the present invention.
