The present invention relates to a covering structure for the face. More specifically, the present invention relates to a covering structure for the face, which can suppress the scattering of droplets generated from the user or the invasion of droplets from the outside, has an excellent sense of stability when worn, and has a comfortable fit. It is a thing.

Conventionally, a hygiene mask that covers the lower half of the user's face and a face shield that covers the entire face have been used in order to prevent the scattering of the user's droplets and the invasion of the droplets from the outside.

A general sanitary mask is composed of a cloth-like mask body made of non-woven fabric or gauze, and ear hooks made of rubber or the like and provided at both ends of the mask body, and most of the mask body. However, it has a structure in which it is worn in contact with the user's nose, lower jaw, cheeks, and the like.

Further, the hygiene mask may have a shape in which a cloth-shaped mask main body and an annular ear hook portion are integrally formed. For example, the hygiene mask described in Patent Document 1 has been proposed.

The hygiene mask described in Patent Document 1 is also worn with most of the mask body in contact with the user's nose, lower jaw, cheeks, etc., similarly to the hygiene mask having an ear hook such as rubber. It has a structure to do.

Further, a general face shield is composed of an annular band portion worn on the user's head and a transparent resin film covering the entire face of the user.

In addition, a general face shield has a structure in which a resin film is provided slightly diagonally with respect to the vertical direction of the user's face from the position corresponding to the frontal region of the user toward the front and lower sides. (See FIG. 22 (b)).

Japanese Unexamined Patent Publication No. 2016-137119

However, conventional hygiene masks, including the hygiene mask described in Patent Document 1, are used because the cloth-like mask body has a structure of being worn in contact with the user's nose, lower jaw, cheeks, and the like. There was a problem that sometimes made me suffocate. Also, if it is worn in hot weather, it tends to cause discomfort.

In addition, with the conventional hygiene mask, the position of the mask body easily shifts due to the movement of the user's mouth or the action of touching a part of the mask with the hand, so the position of the mask body is set to the position where the face fits each time. I had to put it back.

This work of returning the position of the mask body is not only troublesome, but also touches the mask by hand, so it can be said that it is not preferable in terms of hygiene.

Further, in the conventional sanitary mask, for example, a mask made of gauze or the like can be washed and used repeatedly, but it has been troublesome to wash and dry after use.

In addition, since the conventional face shield defines the position and orientation of the resin film with the band portion attached to the user's head, the band portion is likely to be displaced due to the movement of the user's head. , There was a problem of lack of stability at the time of mounting.

Further, since the conventional face shield has a long length from the band portion to the lower end portion of the resin film located at the tip of the user's chin, the soft resin film is easily deformed. Therefore, it is necessary to keep a distance between the face and the resin film, which leads to instability at the time of wearing and a problem that splashes cannot be sufficiently prevented.

In addition, since the resin film is provided diagonally toward the front and lower sides of the conventional face shield, there is a distance between the user's lower jaw and the resin film, which causes diffusion of droplets and droplets from the outside. There was a risk that the intrusion could not be sufficiently suppressed.

The present invention has been devised in view of the above points, and can suppress the scattering of droplets generated from the user or the intrusion of droplets from the outside, and has an excellent sense of stability when worn. It is intended to provide a covering structure for the face that is comfortable to wear.

In order to achieve the above object, the covering structure for the face of the present invention is a frame body extending along the left-right direction of the user's face, and is configured to be supportable on at least one of the user's nose and cheeks. Covers the mounted frame portion, the shield support portion provided on both end sides of the mounting frame portion and protruding to the side opposite to the side facing the user, and at least the area below the user's nose. A shield portion that is formed to a possible size and is bendable, and has a shield portion that is configured so that a part of the peripheral portion side can be attached to the shield support portion, and the shield portion of the user. A drawing frame portion provided on the lower peripheral edge portion corresponding to the jaw portion and bending the lower end peripheral edge portion of the shield portion with a larger curvature than the upper peripheral edge portion on the opposite side of the lower peripheral edge portion of the shield portion. It is provided with a head mounting portion provided at both ends of the mounting frame portion and configured to be mountable on the user's ear or the back of the head.

Here, the mounting frame portion is a frame body extending along the left-right direction of the user's face, and is configured to be supportable on at least one of the user's nose and cheeks, whereby the user's nose or the user's nose or The wearing frame portion can be supported by the cheeks, and the covering structure for the face can be attached. That is, by stably supporting the mounting frame portion with the parts in the center of the user's face, such as the nose or cheeks, it is possible to prevent the occurrence of misalignment during mounting. In addition, the comfort when supporting the wearing frame portion with the nose and cheeks is close to the feeling of wearing the frame of the spectacles, and it is possible to reduce the discomfort when wearing the glasses. Further, the mounting frame portion is located near the center of the user's face, and the distance between the portion supported by the face of the frame body and the lower end portion of the shield portion (the tip of the user's chin) is shortened. , The shield part is less likely to be deformed. As a result, the instability at the time of wearing due to the deformation of the shield part is reduced, and the distance between the shield part and the face can be shortened. , Problems such as intrusion can be suppressed.

Further, since the shield portion is formed in a size that can cover at least the area below the user's nose and is a bendable film-like body, the user can talk, sneeze, etc. at the shield portion. It is possible to suppress the scattering of the droplets generated when the sneezing occurs to the outside and the invasion of the droplets from the outside to the user's face side.

In addition, shield support portions are provided on both ends of the mounting frame portion and are formed so as to project from the side facing the user, and a part of the peripheral portion side of the shield portion can be attached to the shield support portion. It is possible to provide the shield portion on the front side of the mounting frame portion from the user's point of view. As a result, a certain space can be provided between the face and the shield portion while only the mounting frame portion is in contact with the user's nose or cheek. That is, it is possible to relieve the suffocation when wearing the product and the burden when the product is worn for a long time.

In addition, even if the mounting position of the covering structure for the face shifts, it is possible to touch only the mounting frame part with the hand without touching the shield part and reattach it to the position that fits the face. It is suitable for hygiene.

Further, the aperture frame portion is provided on the lower peripheral edge portion of the shield portion corresponding to the user's chin portion, and the lower end peripheral edge portion of the shield portion is set from the upper peripheral edge portion on the opposite side of the lower peripheral edge portion of the shield portion. By bending with a large curvature, it is possible to prevent a large gap from being formed between the periphery of the user's chin and the shield. As a result, while making the size of the shield portion compact, it is possible to sufficiently suppress the scattering of droplets to the outside and the intrusion of droplets from the outside onto the user's face side.

In addition, the head mounting portion is provided at both ends of the mounting frame portion so that it can be attached to the user's ear or back of the head, so that the mounting frame portion is supported by the user's nose or cheek. It can be maintained and a covering structure for the face can be attached.

Further, when the shield portion is made of a transparent or translucent material, the face and mouth of the user can be visually recognized. That is, for example, a covering structure for a face can be used even in a case where it is necessary to show a facial expression to another person.

Further, when the shield portion is formed in a mask shape having a size capable of covering the area below the user's nose, and at least a part of the upper peripheral portion is configured to be attachable to the shield support portion, About the lower half of the user's face can be protected by the shield part.

Further, the shield support portion is formed by connecting both ends of the mounting frame portion, and is provided with a gap between the mounting frame portion and the shield support portion and the mounting frame portion. When the lid shield portion is provided, the area of the gap between the shield support portion and the frame portion, that is, the region between the shield portion and the user's face is scattered from above or foreign matter is invaded. Can be suppressed. As a result, the area of the user's face covered with the shield portion is more sufficiently protected.

Further, when the shield support portion is provided with a notch on the side facing the user and a part on the drawing frame portion side, and the shield portion has a hole formed at a position corresponding to the notch. The notch and the hole can be used as an air passage between the area surrounded by the lid shield portion and the shield portion and the outside. As a result, heat and air are less likely to be trapped in the lid shield portion and the range surrounded by the shield portion, and comfort at the time of wearing can be improved.

Further, when the shield portion is formed in a face shield type having a size capable of covering the entire face of the user, the entire face of the user can be protected by the shield portion.

Further, when the shield support portion is formed to have a length that can be attached only to the peripheral edge portion side of the shield portion, the shield support portion is located only in the vicinity of both ends of the mounting frame portion, and is located in the center of the shield portion. The portion side has a shape without a shield support portion. As a result, the user's field of view is less likely to be obstructed by the shield support portion, and the visibility at the time of mounting can be improved.

The covering structure for the face according to the present invention can suppress the scattering of droplets generated from the user or the intrusion of droplets from the outside, and has an excellent sense of stability when worn, providing a comfortable fit. It has.

Further, the rubber portion 7 for ear hooks referred to here corresponds to the head-mounted portion according to the claims of the present application.

Further, the mounting frame portion 2 and the holding frame portion 3 form a frame body on the frame, and both members are integrally formed of polypropylene. Further, the mounting frame portion 2 is a member supported by the upper part of the user's nose. Further, the holding frame portion 3 is a member to which the upper end of the front shield portion 4 is attached.

Further, the front shield portion 4 is a member that covers the region below the nose of the user's face, and is formed of a transparent polypropylene film. That is, the front shield portion 4 is a main member for suppressing the scattering of droplets generated when the user has a conversation, sneezing, etc., and the invasion of droplets from the outside to the user's face side.

Further, the front shield portion 4 is flexible, and with the front shield portion 4 attached to the holding frame portion 3 and the straightening frame portion 6, the front shield portion 4 also has a curved shape according to the curved shape of each frame. Will be.

Further, the upper surface shield portion 5 is arranged in the gap 8 between the mounting frame portion 2 and the holding frame portion 3 (see FIG. 1), and is a member for suppressing the intrusion of droplets or the like from above the mask 1. The upper surface shield portion 5 is formed of a transparent polypropylene film like the front shield portion 4.

Further, the straightening frame portion 6 is a curved frame member for forming the lower end edge portion of the front shield portion 4 into a shape that is larger than the upper end edge portion of the front shield portion 4. Further, the straightening frame portion 6 is made of the same polypropylene as the mounting frame portion 2 and the holding frame portion 3.

Further, the ear hook rubber portion 7 is formed of an annular rubber and serves as a portion to be hooked on the ear when the user wears the mask 1.

Here, the mounting frame portion 2 and the holding frame portion 3 do not necessarily have to be integrally formed, and each is provided as a separate member, and these are connected to form a frame body on the frame. May be good.

Further, the material forming the mounting frame portion 2, the holding frame portion 3 and the straightening frame portion 6 is not limited to polypropylene, and a frame body having a desired shape can be formed, and when the user wears the mask 1. Any light material that does not feel a burden can be used as appropriate.

The shape of the mounting frame portion 2 is not particularly limited as long as it can be supported by the user's nose or cheeks. For example, a frame having a shape that is supported by the cheek of the user, such as the mounting frame portion 2a of the face shield 1a described later, can be adopted as the shape of the mounting frame portion of the mask 1.

Further, the shape of the holding frame portion 3 is particularly limited as long as it is a shape protruding forward of the mounting frame portion 2 so that a space is provided between the front shield portion 4 and the user's face. It's not a thing.

Further, it is not always necessary that the mask 1 is provided with the upper surface shield portion 5. However, since it is possible to prevent the intrusion of droplets or the like into the region of the gap 8 between the mounting frame portion 2 and the holding frame portion 3, that is, the invasion of the droplets or the like from above the mask 1, the upper surface shield portion is attached to the mask 1. 5 is preferably provided.

Further, as a structure for wearing the mask 1, it is not always necessary to adopt the ear hook rubber portion 7 which is formed of annular rubber and is hooked on the user's ear. For example, as shown in FIG. 12, a head mounting portion 71 that holds the two rubbers 70 on the back of the head of the user may be adopted. Further, here, a structure in which one rubber or a rubber belt on one band is held by the back of the head of the user can also be adopted. The same applies to the head mounting portion of the face shield 1a, which will be described later.

Hereinafter, a more detailed structure will be described.

First, the mounting frame portion 2 is composed of a frame convex portion 20 projecting forward when viewed from the user, and a frame main body portion 21 extending in the left-right direction from the convex portion 20 and formed in a slightly curved shape. (See FIGS. 1, 2 and 3).

Further, as shown in FIG. 3, the frame convex portion 20 is a portion supported by the upper part of the nose when the user wears the mask 1. Further, the frame main body portion 21 is a portion arranged along a curved line of the face from the nose to the cheeks when worn. In FIG. 3, the location of the user's nose is indicated by a reference numeral N.

The frame main body 21 has a structure in which the convex portion 20 of the frame is in contact with the upper part of the nose of the user without touching the face of the user, and the position of the mask 1 in the vertical direction is maintained (FIG. 3).

Further, through holes 22 are formed in both ends of the mounting frame portion 2 in the vertical direction, and the ear hook rubber portions 7 are inserted therethrough (see FIGS. 1 and 2).

Further, the holding frame portion 3 projects forward from both ends of the mounting frame portion 2, connects both ends of the mounting frame portion 2, and is formed in a slightly curved shape. Further, four pins 30 projecting rearward are formed on the rear surface (the surface on the user side) of the holding frame portion 3 (see FIG. 4). Further, the pin 30 is integrally formed with the holding frame portion 3.

Further, each pin 30 of the holding frame portion 3 is a member that fits into the mounting hole 40 provided on the upper side of the front shield portion 4, and the front shield is formed by fitting the pin 30 and the mounting hole 40. The upper end portion of the portion 4 can be attached to the holding frame portion 3 (see FIG. 4).

The plurality of upward arrows shown in FIG. 4 indicate the direction in which the mounting hole 40 of the front shield portion 4 is aligned with the position of the pin 30.

Further, a plurality of film receiving portions 50 and claw portions 51 are formed on the frame body composed of the mounting frame portion 2 and the holding frame portion 3 (see FIGS. 4 and 5). The film receiving portion 50 and the claw portion 51 are integrally formed with the frame body.

The film receiving portion 50 supports the upper surface shield portion 5 from below, and the claw portion 51 holds the upper surface shield portion 5 from above.

That is, in the vertical direction, the upper surface shield portion 5 is sandwiched between the plurality of film receiving portions 50 and the claw portions 51, and is attached to the frame body composed of the mounting frame portion 2 and the holding frame portion 3 (FIG. 5). reference).

The plurality of downward arrows shown in FIG. 5 indicate the direction in which the upper surface shield portion 5 is attached to the gap 8 between the mounting frame portion 2 and the holding frame portion 3.

Further, on the rear surface (the surface on the user side) of the straightening frame portion 6, three pins 60 projecting rearward are formed (see FIGS. 2 and 6). Further, on the rear surface of the straightening frame portion 6, two claw portions 61 formed in a substantially L shape are formed. The pin 60 and the claw portion 61 are integrally formed with the straightening frame portion 6.

Further, each pin 60 of the straightening frame portion 6 is a member that fits into a mounting hole 41 provided on the lower side of the front shield portion 4. Further, the claw portion 61 of the straightening frame portion 6 is a member that fits into the mounting recess 42 provided on the lower side of the front shield portion 4 (see FIGS. 2 and 6).

The pin 60 and the mounting hole 41 are fitted, and the mounting recess 42 is inserted between the claw portion 61 and the main body of the straightening frame portion 6 to be fitted, so that the lower end edge portion of the front shield portion 4 is fitted. The central portion can be attached to the straightening frame portion 6 (see FIGS. 2, 4 to 6).

Further, with reference to FIGS. 1, 2, 4, and 7 to 10, the advantage of greatly bending the lower edge portion of the front shield portion 4 in the straightening frame portion 6 will be described. FIG. 7 is a schematic front view of the mask 1. 8 (a) is a sectional view taken along line AA shown in FIG. 7, and FIG. 8 (b) is a sectional view taken along line BB shown in FIG. 7. FIG.

Further, FIG. 9 (a) is a schematic view showing the positional relationship between the contour line of the face and the mask 1 at a height position near the lower jaw of the user in the vertical direction, and FIG. 9 (b) is a schematic view showing the positional relationship between the mask 1 and the face in the vertical direction. It is a schematic diagram which shows the positional relationship between the contour line of a face and the mask 1 at the height position near the nose of a user. Further, FIG. 10 is a schematic view of a state in which the mask 1 is worn by the user as viewed from the side.

First, the upper end edge portion of the front shield portion 4 is maintained in a bent shape by the holding frame portion 3. Further, the lower end edge portion of the front shield portion 4 is maintained in a curved shape by the straightening frame portion 6 (see FIGS. 1, 2, 4, and 7).

Further, the curved shape of the straightening frame portion 6 has a larger curvature than the curved shape of the holding frame portion 3 (see FIG. 4).

Therefore, in the front shield portion 4, the curvature of the lower end edge portion 400 bent by the straightening frame portion 6 is larger than the curvature of the upper end edge portion 401 bent by the holding frame portion 3 (FIG. 8 (FIG. 8). a) and FIG. 8 (b)).

As described above, the bending of the lower end edge portion 400 of the front shield portion 4 is larger than the bending of the upper end edge portion 401 due to the straightening frame portion 6, so that the bending of the lower end edge portion 401 is larger than the bending of the upper end edge portion 401. It is possible to prevent a large gap from being formed between the front shield portion 4 and the jaw portion 100 (see FIG. 9A).

In this way, by greatly bending the lower end edge portion 400 of the front shield portion 4 by the straightening frame portion 6, the user's face (near the chin) is compared with the state where the straightening frame portion 6 is not attached to the front shield portion 4. ) And the front shield portion 4 so that the distance does not increase.

Note that FIG. 9B schematically shows the positional relationship between the user's nose 101 and the upper edge portion 401 of the front shield portion 4 for reference. Further, FIG. 10 shows a side view of the state in which the mask 1 is worn by the user, and the distance between the user's face (near the chin) and the front shield portion 4 is determined by the correction frame portion 6. Indicates a state where there is no large space.

The structure of the air passage provided in the holding frame portion 3 and the front shield portion 4 will be described with reference to FIGS. 2, 4 and 11.

First, substantially rectangular air holes 43 are provided at four locations on the upper portion of the front shield portion 4 (see FIGS. 2, 4, and 11). Further, a notch 31 is formed at a position corresponding to the air hole 43 on the rear surface of the holding frame portion 3 (see FIGS. 4 and 11).

The air hole 43 of the front shield portion 4 and the notch 31 of the holding frame portion 3 serve as an air passage through which air flows outward from the region surrounded by the front shield portion 4 and the upper surface shield portion 5.

As a result, when the mask 1 is attached, heat and air are less likely to be trapped in the area surrounded by the front shield portion 4 and the upper surface shield portion 5, and the comfort at the time of attachment can be improved. In FIG. 11, the flow of air through the air hole 43 and the notch 31 is indicated by reference numeral X.

Here, it is not always necessary to form the air hole 43 of the front shield portion 4 and the notch 31 of the holding frame portion 3. However, as described above, it is possible to form an air passage through which air flows outward from the area surrounded by the front shield portion 4 and the top shield portion 5, and it is possible to improve the comfort when wearing the mask 1. From the possible points, it is preferable that the air hole 43 of the front shield portion 4 and the notch 31 of the holding frame portion 3 are formed.

In the mask 1 described above, the rubber portion 7 for ear hooking is hooked on the user's ear, and the frame convex portion 20 of the mounting frame portion 2 is supported by the upper part of the nose so that the mask 1 can be worn. ..

When the mask 1 is attached, the front shield portion 4 can suppress the scattering of droplets generated when the user talks, sneezes, etc., and the invasion of droplets from the outside to the user's face side. ..

Further, as described above, in the mask 1, the frame convex portion 20 can be supported and attached by the upper part of the nose, and the attached frame portion 2 can be stably supported by the central portion of the user's face. can. As a result, the mask 1 has a structure that does not easily shift when attached.

Further, the comfort of supporting the wearing frame portion 2 on the upper part of the nose is close to the feeling of wearing the frame of the spectacles, and the feeling of discomfort at the time of wearing is reduced.

Further, a holding frame portion 3 is provided in front of the front shield portion 4, and the holding frame portion 3 does not come into contact with the user's face to provide a certain space between the face and the front shield portion 4. Can be done.

As a result, it is easier to breathe when wearing the sanitary mask than before, and the burden felt by the user can be eased even when the mask is worn for a long time.

Further, when the mounting position of the mask 1 is displaced, the mask 1 can be reattached to a position that fits the face by touching only the mounting frame portion 2 without touching the front shield portion 4 to which droplets or the like adhere. It is hygienic.

Further, the straightening frame portion 6 has a structure in which a large gap is unlikely to occur between the front shield portion 4 and the jaw portion 100 at the position of the jaw portion 100 of the user. Therefore, while making the size of the front shield portion 4 compact, it is possible to sufficiently suppress the scattering of droplets to the outside and the intrusion of droplets from the outside onto the user's face side.

Further, the mask 1 is provided with the upper surface shield portion 5, so that the mask 1 has a structure capable of suppressing intrusion of droplets or the like from above the mask 1 into the inside.

Such a structure of the mask 1 can suppress the scattering of droplets generated from the user or the intrusion of droplets from the outside, has an excellent sense of stability when worn, and has a comfortable wearing comfort. ..
