Description

The present invention relates to a mask that exposes the nostrils to facilitate breathing and suppresses droplet diffusion from the mouth.

Masks that cover the mouth and nostrils are used to prevent virus infections and pollen allergies, but if they need to be worn for a long time, they may become stuffy and have difficulty breathing, making the glasses cloudy. Etc. have occurred. Therefore, there is known a mask provided with a notch for exposing the nose in order to facilitate breathing and prevent fogging of the glasses (see Patent Document 1). Further, a mask as a mouth seal made of a transparent resin located at the front part of the face is known to suppress the diffusion of droplets from the mouth and facilitate the breathing of the user (see Patent Document 2). ..

However, although the mask described in Patent Document 1 facilitates breathing through the nostrils, it is necessary to add a manufacturing process for providing a notch for exposing the nose, which leads to an increase in manufacturing cost. .. Further, according to the mask described in Patent Document 2, since the transparent resin plate is provided with the jaw receiving portion, the distance from the transparent resin plate is maintained and breathing is facilitated, but from the periphery of the transparent resin plate. Splash diffusion cannot be sufficiently suppressed. Furthermore, if the mask that covers the mouth and nostrils is moved downward to expose the nostrils, breathing will be easier, but the mask will loosen, causing droplets to leak from the end of the mask and from the mouth. It is not possible to sufficiently suppress the spread of droplets.

An object of the present invention is to provide a mask capable of exposing the nostrils to facilitate breathing and sufficiently suppressing the diffusion of droplets from the mouth.

In order to solve the above problems, the mask according to the present invention has a mask main body covering the user's mouth and a string shape provided on both the left and right sides of the mask main body and engaged with the user's ear. The mask main body is provided with an ear hook portion, and the mask main body portion has a peripheral edge portion that has been sewn so as to sandwich the peripheral edge thereof with a band-shaped cloth, and the mask main body when worn on a user. The vertical distance between the upper and lower ends of the center and the lower end of the center in the lateral direction along the surface of the mask main body is set to a predetermined fixed value within the range of 80 mm or more and 110 mm or less.

According to such a configuration, the vertical distance between the upper and lower central ends of the mask main body in the lateral direction along the surface of the mask main body is a predetermined fixed value within a range of 80 mm or more and 110 mm or less. Therefore, regardless of whether it is a flat mask or a three-dimensional mask, the mask covers the area from below the user's jaw to just below the nose, preventing the emission of droplets from the mouth and exposing the nose. Therefore, it is possible to facilitate breathing through the nostrils. In particular, in the case of a male adult, the vertical distance is preferably 100 mm, and in the case of a female adult, it is preferably 90 mm. Then, since the peripheral edge portion that has been sewn (piping processed) so as to sandwich the peripheral edge of the mask main body portion with the band-shaped fabric is formed and has a predetermined thickness, it is easy to come into contact with the surface of the face and the peripheral edge of the mask main body portion. The diffusion of droplets from the part can be further suppressed.

In the mask according to the present invention, the space between the central upper end and the central lower end in the lateral direction of the mask main body when worn on the user can be configured to have a shape that bulges outward.

According to such a configuration, the space between the lateral central upper end and the central lower end of the mask main body when attached to the user becomes a mask having a shape that bulges outward, that is, a three-dimensional shape. , It becomes a shape that does not easily create a gap with the surface of the face according to the shape of the human face. In addition, since a space is created between the mask and the mouth, conversation becomes easier and the heat and heat are reduced.

In the mask according to the present invention, the ear hook portion is a pair of string-shaped members whose ends are connected to the top and bottom of the left and right side ends of the mask main body, and the length of the string-shaped member can be adjusted. The adjusting tool can be provided on each of the pair of string-shaped members.

According to such a configuration, since the adjuster that can adjust the length of the string-shaped member constituting the ear hook is provided, the optimum length for the user is suppressed by suppressing the gap between the face surface and the mask body. Since it can be adjusted to the size, it is possible to suppress the scattering of droplets from the mouth. Further, by adjusting the length of the string-shaped member, it is possible to suppress the occurrence of pain in the ear due to long-term use.

In the mask according to the present invention, the mask main body may have a laminated structure in which twisted fabrics are provided on the outer surface side and the inner surface side, and nanofiber non-woven fabric is provided between the twisted fabrics on the outer surface side and the inner surface side. it can.

According to such a configuration, for example, by using a twisted fabric as a gauze fabric, it is possible to provide a comfortable mask that feels good on the mouth and its surroundings, and nanofibers can be provided between the twisted fabrics. Since a non-woven fabric is used, it is possible to suppress the release of droplets from the mouth to the outside as much as possible. In addition, it is possible to suppress the invasion of viruses, pollen, etc. from the outside into the mouth.

According to the present invention, it becomes a mask that covers the range of the upper lip from below the chin to just below the nose of the user, and can facilitate breathing through the nostrils. Then, the peripheral edge of the mask body easily comes into contact with the surface of the face, and the diffusion of droplets from the peripheral edge to the outside can be suppressed.

FIG. 1 is a perspective view when a mask is used according to an embodiment of the present invention. FIG. 2 is a plan view of the mask shown in FIG. 1 developed. FIG. 3 is a partially enlarged perspective view of the mask shown in FIG. FIG. 4 is a side view of the mask shown in FIG. 1 when a person wears it.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

The mask according to the embodiment of the present invention is shown in FIGS. 1, 2 and 4. FIG. 1 is a perspective view of the mask according to the embodiment of the present invention when used, and FIG. 2 is a plan view of the mask shown in FIG. 1 developed. FIG. 4 is a side view of the mask shown in FIG. 1 when a person wears it.

As shown in FIGS. 1, 2 and 4, the mask 11 includes a mask main body 12 for covering the mouth from the chin in order to prevent droplets from scattering from the mouth, and both left and right sides of the mask main body 12. It is a configuration including a pair of ear hook portions 13a and 13b provided in the above.

The mask main body 12 has a substantially inverted trapezoidal shape in which the upper side 12a is longer than the lower side 12b. By making the upper side 12a longer than the lower side 12b, when the user wears the mask 11, the left side 12c and the right side 12d, which are the left and right side sides of the mask main body 12, are substantially vertical. Further, in the mask body 12, the outer surface side (outside air side surface) and the inner surface side (mouth side surface) are twisted fabrics (“gauze fabric” manufactured by Asano Twisted Yarn Co., Ltd.), and the outer twisted fabric and the inner side. It has a three-layer laminated structure in which a nanofiber non-woven fabric is provided as an intermediate layer between the plyed fabrics. By using the twisted fabric on the outer surface side and the inner surface side, the feel is improved, and the tactile sensation of the mouth and its peripheral portion is particularly comfortable. In addition, the mask using the twisted fabric has a higher heat retention and moisturizing effect than the mask using only the non-woven fabric, and can keep the throat comfortable. The plyed fabric has a front surface and a back surface, and the back surface having a slightly raised feeling is arranged on the nanofiber non-woven fabric side, which is an intermediate layer, to make the tactile sensation more comfortable. Nanofiber non-woven fabric is a non-woven fabric made of ultrafine fibers in units of one millionth of a millimeter, manufactured using a non-woven fabric manufacturing technology called electrospinning, and has a large specific surface area, is thin and soft. It has features such as high adhesion and is a material suitable for various filters such as medical treatment. The nanofibers used in the mask 11 suppress the permeation of droplets from the mouth to the outside, and can exhibit high filter performance. A tag 23 for displaying the product name, material, etc. is attached or sewn on the surface of the twisted fabric on the outside of the mask main body 12.

The mask main body portion 12 is formed with peripheral edge portions 15 (15a, 15b, 15c, 15d) that have been sewn (piping processed) so as to sandwich the peripheral edge thereof with a strip-shaped fabric. As the strip-shaped fabric, a fine-grained twisted fabric having higher strength than the twisted fabric used for the mask main body 12 is used. As shown in FIG. 2, the upper peripheral edge portion 15a is formed by sewing so as to sandwich the upper end portion including the upper side 12a of the mask main body portion 12 with the elongated strip-shaped fabric. The upper peripheral edge is formed to have a width of about 7 mm. Further, the strip-shaped fabrics extending to the left and right from the upper peripheral edge portion 15a are overlapped and sewn to form the string-shaped members 17a and 17b of the ear hook portions 13a and 13b. The lengths of the string-shaped members 17a and 17b are adjusted by the adjusting tools 25 and 26 as described later, and are formed so as to be in the range of, for example, 300 mm to 350 mm.

Similarly to the above, the lower peripheral portion 15b is formed by sewing the lower end portion including the lower side 12b of the mask main body portion 12 so as to be sandwiched between the elongated strip-shaped fabrics. Like the upper peripheral edge portion 15a, the lower peripheral edge portion 15b is formed to have a width of about 7 mm. The strip-shaped fabric is sewn on top of each other so as to extend from the lower peripheral edge portion 15b to the left and right, and is connected to the ring-shaped connecting rings 18a and 18b as extension ends 14a and 14b so as to protrude by about 5 mm, respectively. The left side 12c and the right side 12d, which are the side sides of the mask main body 12, are also sewn so as to be sandwiched between the elongated strip-shaped fabrics to form the left peripheral portion 15c and the right peripheral portion 15d, respectively. Further, the left peripheral edge portion 15c and the right peripheral edge portion 15d are also sewn in the same manner to form a width of about 6 mm.

The mask main body 12 is a mask having a shape in which the space between the vicinity of the central upper end and the vicinity of the central lower end in the lateral direction of the mask main body 12 when worn on the user bulges outward, that is, a three-dimensional shape. .. At this time, the vertical distance along the surface of the mask main body 12 between the central upper end and the central lower end in the lateral direction is the length of the apex 21 which is a curved line protruding outward and the width of the upper peripheral edge 15a. The total of the length and the width of the lower peripheral edge portion 15b is a fixed value of about 100 mm. That is, no pleated folds are formed on the surface of the mask body 12, and the vertical distance between the upper and lower ends of the center in the lateral direction along the surface of the mask body 12 is fixed. It becomes the value. This is because the nose is exposed and the mask always covers the area from below the chin to just below the nose of the user. Further, the length of the upper side 12a of the mask main body 12 is 240 mm, and the length of the lower side 12b is 190 mm. The size of the mask described above is mainly for men (adults), and for women (adults), the preferred values are the lateral center upper end and center lower end of the mask body 12 when worn. The vertical distance along the surface of the mask main body 12 is 90 mm, the length of the upper side 12a of the mask main body 12 is 220 mm, and the length of the lower side 12b is 170 mm.

Next, the string-shaped members 17a and 17b of the ear hooks 13a and 13b and the adjustment of their lengths will be described with reference to FIG. FIG. 3 is a partially enlarged perspective view of the ear hook portion 13b of the mask 11. Since the ear hook portion 13a and the ear hook portion 13b have the same structure, the ear hook portion 13b will be described with reference to FIG. The elongated strip-shaped fabric that forms the upper peripheral edge 15a by sewing so as to sandwich the peripheral edge including the upper edge 12a of the mask main body 12 is extended to the right side as it is (about 300 mm), and the string-shaped member is sewn. 17b is formed. A string-shaped member 17b, an adjuster 26 through which the string-shaped member 17b is inserted to adjust the length, an extension end portion 14b which is a portion extending to the right from the lower peripheral edge portion 15b, and an extension end portion 14b. The ear hook portion 13b is composed of the connection ring 18b to which the portion 14b is connected. The same applies to the ear hook portion 13a.

The adjuster 26 is formed of a square annular member 26a and a rod-shaped connecting member 26b that connects a pair of opposite sides of the annular member in the vicinity of the middle. The annular member 26a is divided into two openings by the connecting member 26b. The connection ring 18b is a circular annular member, and an extension end portion 14b extending to the right from the lower peripheral edge portion 15b is fixed by folding back stitching after insertion. Then, the tip of the string-shaped member 17b is inserted through one opening of the annular member 26a of the adjusting tool 26, and the other opening is inserted so as to involve the connecting member 26b. Next, the tip of the string-shaped member 17b is inverted so as to be inserted into the connecting ring 18b and then returned, and further wound around the connecting member 26b so as to engage with the adjusting tool 26. The entire length of the string-shaped member 17b can be shortened by pulling the tip of the string-shaped member 17b, and can be lengthened by loosening it so as to return it. The adjuster 25 (annular member 25a, connecting member 25b) is also the same as the adjuster 26.

Next, the wearing of the mask 11 according to the embodiment of the present invention will be described with reference to FIG. FIG. 4 is a side view of the mask 11 when a person wears it. The length of the string-shaped member 17a (17b) is adjusted by the adjuster 25 (26), and the ear hook portion 13a (13b) is attached to the ear by hanging it on the back side of the ear. If the string-shaped member 17a (17b) is too long or too short, it is adjusted again to suppress the diffusion of droplets from the mask body 12. When the mounting position is stabilized by hiding the chin tip by the lower peripheral edge portion 15b of the mask main body portion 12, it is along the surface of the mask main body portion 12 between the lateral central upper end and the central lower end of the mask main body portion 12. The total length of the vertical distance 31, that is, the width of the upper peripheral edge 15a, the length of the apex 21, and the width of the lower peripheral edge 15b is 100 mm, which is a fixed value that does not expand or contract. The upper peripheral edge portion 15a of the portion 12 covers the upper lip and reaches the position below the nose.

As described above, the user wearing the mask 11 in a stable position can secure breathing through the nostrils by covering the mouth and its surroundings and always exposing the nose. Further, the peripheral edge portion 15 (upper peripheral edge portion 15a, lower peripheral edge portion 15b, left peripheral edge portion 15c, right peripheral edge portion 15d) sewn around the mask main body portion 12 with a band-shaped fabric is more than the other portion of the mask main body portion 12. Is also thickly formed, it is possible to suppress the generation of gaps with the surface of the face and prevent the leakage of droplets from the mouth. Further, since the lengths of the string-shaped members 17a and 17b of the ear hooks 13a and 13b can be adjusted by the adjusting tools 25 and 26, the generation of a gap between the peripheral edge portion 15 and the face can be further suppressed. In the case of an ear hook made of a thin and round rubber cord, it is difficult to adjust the length, and it may bite into the ear and cause pain. However, the length of the mask 11 according to the present embodiment is adjustable and is impossible. It can be set to an appropriate length for each user.

Since the mask body 12 has a three-layer structure in which a nanofiber non-woven fabric is sandwiched between two twisted fabrics, it feels good on the mouth of the face and suppresses the diffusion of droplets from the mouth to the outside. Can be done. In addition, the main cause of fogging of glasses when using a mask is exhaled air leaking from the gap between the mask and the face. Especially when the temperature difference between exhaled air and outside air is large, the water vapor contained in the exhaled air cools and becomes water droplets, causing cloudiness of the lens. However, since the nose is exposed, it becomes difficult for the exhaust from the nostrils to come into direct contact with the glasses, which prevents the glasses from fogging.

The above-mentioned mask 11 is a three-dimensional mask in which the apex 21 of the mask main body 12 is curved and the central portion bulges outward when used, but the mask is not limited to the three-dimensional mask and may be a flat mask. .. The point is that the distance between the upper and lower sides of the mask body 12 along the surface of the mask body 12 between the lateral center upper end and the center lower end of the mask body 12 at the time of mounting is a predetermined fixed value within the range of 80 mm or more and 110 mm or less. If so, it is possible to provide a mask that can expose the nose and cover from the chin to the entire upper lip. Further, the string-shaped members 17a and 17b of the ear hooks 13a and 13b are formed by extending the strip-shaped fabric forming the upper peripheral edge portion 15a to the left and right and sewing, but the present invention is not limited to this. For example, the mask main body 12 may be retrofitted with separately prepared string-shaped members 17a and 17b sewn on both ends.

Although the embodiments and examples of the present invention have been described above, the embodiments and examples are presented as examples, and the scope of the invention is not intended to be limited. These novel embodiments described above can be implemented in various other embodiments, and various omissions, replacements, and changes can be made without departing from the gist of the invention. These embodiments and examples thereof are included in the scope and gist of the invention, and are also included in the invention described in the scope of claims for utility model registration.

As described above, the mask according to the present invention covers the area from below the user's jaw to the upper lip just below the nose, so that the nose can be exposed and breathing through the nostrils can be facilitated. Since the peripheral edge of the main body easily comes into contact with the surface of the face and has the effect of further suppressing the diffusion of droplets from the peripheral edge, it is useful as a mask for covering the user's mouth.
