Description

[Technical field]

[0001] The present invention relates to a disposable mask that can be used as a general industrial mask for dust prevention and food hygiene measures, a medical mask for infection prevention, and a mask for everyday use for hay fever prevention and infection prevention. [Background technology]

[0002] Conventionally, disposable masks have been known that cover the mouth and nose of a user to prevent the user from inhaling dust, pollen, bacteria, and viruses, and to prevent droplets from the user. These masks can be used as general industrial masks for dust prevention and food hygiene measures, medical masks for infection control, and masks for everyday use to prevent hay fever and infection.

[0003] Patent Document 1 discloses, as such a disposable mask, a disposable dust mask consisting of a filter part formed in a substantially hemispherical shape so as to cover the nose and mouth, a face contact cushion that extends from the entire outer periphery of the filter part to the center and has openings in the parts located at the nose and mouth, and a tightening string.The peripheral part of the filter part that covers the user's mouth and nose is provided with a height difference from the user, and the face contact cushion is provided on that peripheral part, thereby making it possible to prevent almost no gap from being formed between the face contact cushion and the face, thereby preventing dust and the like from leaking in.

[0004] [Patent Document 1] JP 2008-49194 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the disposable dust mask described in Patent Document 1, the face cushion is provided at least on the imaginary surface including the outer periphery or toward the inner space on the filter side, so that there is a risk of a gap being generated between the user's face and the face cushion due to differences in the size, skeletal shape, and fleshiness of the user's face, allowing foreign matter such as dust to flow in. In addition, when used for other purposes, there is a similar risk of foreign matter flowing in or droplets from the user flowing out.

[0006] Therefore, the present invention has been made in consideration of the above problems, and aims to provide a disposable mask that fits closely to the user to prevent the user from inhaling dust, pollen, and droplets from the outside, and prevents droplets from escaping from the user. [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, a disposable mask according to an embodiment of the present invention will be described in detail with reference to the drawings. The embodiment described below is a preferred specific example for carrying out the present invention, and therefore various technical limitations are imposed. However, the present invention is not limited to this embodiment unless otherwise specified in the following description to limit the invention. In addition, "upper", "lower", "front", "rear", "left" and "right" in the description are determined based on the wearer's head. That is, the top side of the head is "upper", the chin side is "lower", the face side is "front", the back side of the head is "rear", the right side of the head is "right", and the left side of the head is "left". For example, in FIG. 1, the upper part is "upper", the lower part is "lower", the right part is "left", the left part is "right", the front of the paper is "front", and the back side of the paper is "rear". Furthermore, the symbol "~" indicating the range in the description includes the numbers on both ends.

[0014] As shown in Figs. 1 to 6, the disposable mask of the present invention comprises a mask body 1, an annular face contact part 2, an attachment string holding part 3, and the like.

[0015] The mask body 1 is a breathable member that has a space S to prevent contact with the mouth and nose of the user U and covers the mouth and nose of the user U. The mask body 1 prevents foreign matter such as dust, pollen, and droplets from entering the space S and prevents droplets from the user U from entering outside the space S, while allowing the user U to breathe. The mask body 1 is made of nonwoven fabric, woven fabric, knitted fabric, etc. formed by combining fibers, and is breathable because it has multiple fine gaps that prevent foreign matter such as dust, pollen, and droplets from passing through but allow gas such as air to pass through.

[0016] In this embodiment, the mask body 1 is composed of a sheet-like left mask part 12 located on the left side of the face of the user U, and a sheet-like right mask part 13 located on the right side of the face of the user U. A fixing part 14 is formed in the approximate center of the mask body 1 in the left-right direction, extending vertically so as to approximately face the eyebrows, nose, and chin of the user U, and fixing the vicinity of the boundary between the left mask part 12 and the right mask part 13 so as to protrude to the front side, which is the outside. In this embodiment, the mask body 1 is formed of a flexible material such as a nonwoven fabric. For these reasons, the mask body 1 can be folded such that the fixing part 14 located in the approximate center is brought closer to either the left or right side of the mask body 1, that is, brought closer to either the left mask part 12 side or the right mask part 13 side so that the space S formed by the left mask part 12 and the right mask part 13 is smaller than that during use, and the tips 22 of the opposing annular face contact parts 2 are not brought closer to each other. 6(a)(b), the mask can be transported or stored in a folded state, and since the annular face contact part 2 near the boundary between the left mask part 12 and the right mask part 13 is not folded at an angle of nearly 180 degrees, the annular face contact part 2 near the boundary between the left mask part 12 and the right mask part 13 does not develop creases or creases even when the mask is unfolded for use, and therefore the mask can maintain close contact with the user's face. In this embodiment, the left mask part 12 and the right mask part 13 are heated and the vicinity of the boundary between the left mask part 12 and the right mask part 13 melts, but in other embodiments, the vicinity of the boundary between the left mask part 12 and the right mask part 13 may be fixed with an adhesive. In addition, since the space S is formed by the left mask part 12 and the right mask part 13 in a shape such as a substantially hemispherical or substantially bowl-shaped, the space S can be prevented from coming into contact with the mouth and nose of the user U during use.In this embodiment, the mask body 1 is formed of two members, the left mask part 12 and the right mask part 13, but in other embodiments, it may be formed of a single member having a space such as a substantially hemispherical or bowl-shaped member so as not to come into contact with the mouth and nose of the user U, or it may be formed of three or more members, or a single member having a gap in a part of the vertical direction of the substantially central part of the left-right direction of the mask body 1 may be used, and the gap may be fixed to form the fixing part 14 so as to protrude outward. Furthermore, in the present invention, the mask body 1 is formed of a single layer member, but in other embodiments, it may be formed by laminating multiple breathable layers.

[0017] The mask body 1 has an entire peripheral edge portion 11 on which an annular face contact portion is fixed on the rear side where the space S is formed, and is formed so as to open toward the user U. In this embodiment, the entire peripheral edge portion 11 has an elliptical shape that is slightly longer in the vertical direction than in the horizontal direction, but in other embodiments, it may have various closed curved shapes such as a circle, an ellipse, or a distorted circle, or may have a polygonal shape such as a hexagon or an octagon. In this embodiment, the entire peripheral edge portion 11 extends toward the space S side in the mask body 1 so as to narrow the opening VS, which is the rearmost end of the space S. That is, the entire peripheral edge portion 11 is formed so that the end sides of the left mask part 12 and the right mask part 13 are curved inwardly toward the space S side. In this embodiment, the entire peripheral edge portion 11 is curved inwardly toward the space S side, but it may be curved or bent outwardly in the vertical, horizontal, or other directions.

[0018] The annular face contact part 2 is an elastic member having a base end 21 fixed to the entire periphery 11 of the mask body 1, and a tip end 22 is provided so as to be oblique toward the user U. The annular face contact part 2 comes into contact with the cheeks and chin of the user U to prevent foreign matter such as dust, pollen, and droplets from entering the space S, and also to prevent droplets from the user U from entering outside the space S. Furthermore, the annular face contact part 2 makes it difficult for the face of the user U to enter the space S of the mask body 1, thereby keeping the internal volume of the space S large, and therefore the efficiency of collecting dust and the like can be achieved without making the mask body 1 larger, which allows the mask body 1 to be made smaller, and the field of view of the user U, including downward, can be expanded. The annular face contact part 2 is made of a sheet-like material such as rubber or resin, such as silicone, butadiene, isoprene, chloroprene, urethane, polypropylene, polyethylene, EVA (ethylene-vinyl acetate copolymer), or foam obtained by foaming them, and has elasticity that deforms when stress is applied but returns to its original shape when the force is removed. In the annular face contact part 2, the tip part 22 is provided obliquely from the opening VS including the entire periphery part 11 toward the rear side, which is the user U side. As a result, the annular face contact part 2 can be easily brought into contact with the face of the user U and easily fit the shape of the user U's face, regardless of the size, skeletal shape, and fleshiness of the user U, and can be closely attached to the user U's face to prevent any gaps from occurring between the face of the user U and the annular face contact part 2, preventing the user U from inhaling dust, pollen, or droplets from the outside, and preventing the outflow of droplets from the user U. In this embodiment, the annular face contact portion 2 has an elliptical annular shape that is slightly longer in the up-down direction than in the left-right direction, but in other embodiments, depending on the shape of the entire peripheral edge portion 11, it may have various closed curved annular shapes such as a circle, an ellipse, a distorted circle, or a polygonal annular shape such as a hexagon or octagon.

[0019] In this embodiment, the annular face contact part 2 bulges outward from the base end 21 fixed to the entire periphery 11 in the up, down, left and right directions, drawing an arc toward the user U, and the tip end 22 is provided at an angle to the opening VS. As shown in Figs. 4 and 5, the curved part 23 is a part that bulges outward from the base end 21 in the up, down, left and right directions, drawing an arc toward the user U, and the tip end 22 side of the annular face contact part 2 is formed longer than the base end 21 side via the curved part 23. In this way, the annular face contact part 2 is curved from the base end 21 extending toward the space S to the tip end 22, that is, by having the curved part 23, when the tip end 22 abuts against the face of the user U, an elastic force works more closely to fit the face of the user U, so that the tip end 22 fits more closely to the face of the user U and no gap is generated between the face of the user U, preventing the user U from inhaling dust, pollen, or droplets from the outside, and preventing the outflow of droplets from the user U. Since the entire peripheral edge 11 is formed such that the end sides of the left mask part 12 and the right mask part 13 are curved inwardly toward the space S, and the annular face contact part 2 is curved from the base end 21 extending toward the space S to the tip end 22, for example, the entire peripheral edge 11 and the base end 21 can be fixed by heat fusion or adhesive with the outer surface of the mask body 1 facing the outer surface of the annular face contact part 2, and then the mask can be made by turning it over so that the front and back are reversed. Note that in this embodiment, the annular face contact part 2 has a curved part 23 between the base end 21 and the tip end 22, but in other embodiments, the curved part 23 may not be present and the tip end 22 may be provided obliquely toward the user U side, such as by making the base end 21 and the tip end 22 approximately V-shaped.

[0020] In the annular face contact part 2, the inclination angle α formed by the tip end 22 with respect to the base end 21 is preferably 5 degrees to 60 degrees, and more preferably 7 degrees to 45 degrees. When the inclination angle α is in this range, it is possible to make closer contact with the face of the user U and prevent a gap from being generated between the face of the user U. In addition, the width of the annular face contact part 2 is preferably 5 to 40 mm, and more preferably 10 to 30 mm. When the width of the annular face contact part 2 is in this range, it is possible to make closer contact with the face of the user U and prevent a gap from being generated between the face of the user U. Note that the width of the annular face contact part 2 does not need to be uniform, and may be uneven, such as the upper side that contacts the bridge of the nose of the user U being long, the lower side that contacts the chin of the user U being short, and the left and right sides that contact the cheeks of the user U being about intermediate between them.

[0021] The attachment string holders 3 are provided on the left and right sides of the mask body 1, and are members for holding the attachment string ST that abuts against the head of the user U, and are members for holding the attachment string ST that abuts from the left and right sides to the rear side of the head of the user U so that the user U can fasten the mask body 1 to the face of the user U. By holding the attachment string ST in the attachment string holders 3, the attachment string ST becomes one with the mask body 1. The attachment string holders 3 are provided with notches 31 through which the attachment string ST is inserted. For example, the attachment string ST, which is a sheet-like rubber string that is thicker than the interval of the notches 31, is inserted into the notches 31 to hold the attachment string ST, and when the tightening feels loose or tight during use, the length of the attachment string ST can be adjusted by sliding the attachment string ST into the notches 31. In this embodiment, two notches 31 are provided at the top and bottom of each of the left and right attachment cord holding parts 3, allowing two attachment cords ST to be provided; however, in other embodiments, one notch 31 may be provided at each of the left and right attachment cord holding parts 3, allowing one attachment cord ST to be provided, or multiple notches 31 may be provided at three or more locations, allowing a corresponding number of attachment cords ST to be provided.

[0022] In this embodiment, the attachment string holder 3 is made of a resin such as polyethylene, polypropylene, or polyester. In this embodiment, the attachment string holder 3 protrudes outward and is sandwiched between the entire periphery 11 and the annular face contact part 2, but in other embodiments, it may be fixed to the left mask part 12 and the right mask part 13 that do not overlap the entire periphery 11, or the disposable mask of the present invention may be formed without providing the attachment string holder 3 and by sandwiching the end of the attachment string ST between the entire periphery 11 and the annular face contact part 2 or by fixing it near the entire periphery 11.
