Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mask which is indispensable for the prevention and treatment of colds, zensoku, hay fever and the like. It is an object of the present invention to provide a hygiene mask having a novel structure.

[0002]

2. Description of the Related Art Most sanitary masks currently on the market have a rectangular main body in its entirety, and its left and right side edges are formed in ear hooking portions. It has a structure in which a ring-shaped ear hook is inserted, or each end of a predetermined length of ear hook is sewn on the left and right side edges of the mask main body and up and down, respectively. When wearing a hygiene mask for the prevention or treatment of hay fever, it is common practice to use the upper edge of the mask body on both wings so that the nostrils and mouth are completely covered. is there.

[0003] Looking at the relationship between the hygiene mask and the face worn in this general usage, the mask body, whose ends are pulled to the left and right by ear hooks, and the whole is slightly nervous, As a result, the central part of the upper edge is pushed outward with the nose tip that protrudes the most from the face, and as a result, the upper edge of the left and right mask bodies from the same place are slightly separated from the nose wing and straightened around the left and right cheekbones The shape of the cheek from the nasal wing to the cheekbone, since it is a structure looking down from directly above, with the nose apex as the apex, and the part extending to the left and right cheekbones constitutes an isosceles triangle with two sides sandwiching the apex Large gaps are formed.

[0004] Under such a wearing condition, the exhaled breath exhaled from the nostril or mouth is exhaled toward the inner surface of the mask main body at a temperature higher than the outside air while maintaining a temperature almost close to the body temperature inside the mask main body. The inside of the mask body tends to move like an updraft, and the internal pressure tends to increase due to the mask body being made of a relatively fine-grained material. Although most of the exhaled breath passed through but did not completely pass, escaped upward from the large left and right gaps that had opened to the cheek from the nose wing to the cheekbone at the upper edge of the mask body, In the case of spectacle users, the exhaled air will cloud the spectacle lens, so even if it is necessary to wear a mask, do not hesitate to wear it, Exhalation from a possible mouth to spit out the inner, so that it may be forced to inconvenient use, such as intentionally spit downward.

On the other hand, when the ear hook is a ring-shaped one that is inserted into the ear hook through portions on the left and right side edges of the mask body, the ear hook through portion gradually wears while the ear hook is worn on the ear. Wrinkled and shrunk by the elasticity of the ear hooks, the vertical dimension of the entire mask becomes considerably smaller, eventually deforming to an outer shape like a rugby ball, so that it can not function as a mask Also, if the ear hooks are of a structure in which each end is sewn on the left and right side edges of the mask body, respectively,
Conversely, instead of shrinking both ends of the mask body, each edge is pulled up and down in the direction of the ear, and as a result, the center of the edge is deformed into a `` C '' shape that is bent forward, and it becomes large on both cheeks This has the disadvantage that a gap is created, which hinders the function of shutting off outside air.

[0006] For this reason, for example, in order to eliminate the gap that opens at the cheek portion from the nose wing to the cheekbone at the upper end edge of the mask main body, the upper end edge of the mask main body can be plastically deformed so that the user can use it without any inconvenience. The mask wearer presses both sides of the nose column toward the face with his / her finger to deform the wire so that the upper edge of the mask body fits the face as much as possible. Although the mask body has been proposed, the mask body will slip off if it is not always pulled on both sides with ear hooks, so wires that should have been plastically deformed by the pulling force will be used for a long time It has been left out of the way that it has to be extended to the inside and cannot be attached to the face, creating a gap and not fulfilling its intended purpose. Invention that has been published in Japanese Unexamined Patent Publication No. 8-80356 "fog not awnings, pollen mask of glasses."
Like, it looks like an ice hockey face mask, but it usually requires considerable courage to wear and use it in the city, and it is never practical This is not the case, and so far, practically no practical hygiene masks suitable for spectacle users are available.

[0007] In addition, the hygiene mask having a general structure so far becomes clogged at both side edges at the time of wearing, or breaks into a "U" shape, thereby hindering the shut-off of the outside air. For the adverse effects, for example, it has been proposed that the front shape of both side edges is to be dealt with in advance in the form of a roll-over trapezoid, but in those improved ones, sewing becomes complicated, Perhaps because there is a problem that the dough removal becomes expensive because it becomes uneconomical, it has not yet become widespread, and at present, those problems remain unresolved, Only traditional structures are provided and used.

In order to cope with the above situation, the present invention has been developed and researched while continuing various trial and error, and has attempted many trial productions. This has led to the completion of a sanitary mask having a novel configuration as described above. The configuration will be clarified while taking up some typical embodiments.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As will be understood from the embodiments of the present invention shown in the drawings, the sanitary mask of the present invention basically has the following structure. That is, a mask body with ear hooks made of a breathable material with relatively fine eyes and having a size capable of completely covering both nostrils and the mouth, and a mountain shape with a gentle upper edge contour, The upper and lower effective width of the hem on both sides is about half the distance from each person's eyes to the nose wing. It is composed of a thin-film strip, and the lower edge of the thin-film strip is integrated over the entire width of the upper edge of the mask body, and the upper and lower effective widths of both skirts of the thin-film strip are larger than the upper edge of the mask body. Is a sanitary mask formed to project upward.

The sanitary mask having the basic structure includes a mask body with ear hooks, which is made of a breathable material having relatively fine eyes and has a size capable of completely covering both nostrils and the mouth. , The upper edge is a gentle mountain shape,
The overall width of the hem on both sides of the ridge is approximately half the distance from the eyes of each person to the nasal wing. From both ends, a side film portion is continuously provided, and a thin film strip made of an elastic material is formed. The lower edge of the thin film strip is integrated with the upper edge of the mask body, and both sides are integrated. The film portions are integrated slightly inward from the left and right side edges of the mask main body, respectively, and the upper and lower effective widths of both skirt portions of the thin film-like band are formed so as to protrude above the upper edge of the mask main body. It includes a sanitary mask whose gist is a simple configuration.

The mask body has a rectangular shape large enough to completely cover at least both the nostrils and the mouth.
Or a filter of a shape similar to that of a human body, which minimizes the invasion of air, pollen, dust, etc. from the outside air into the body as much as possible when worn, allowing the outside air to be sucked directly through both nostrils and mouth. It functions as a gauze, bleached cotton, non-woven fabric,
Synthetic fabrics, various air-permeable materials that have been widely used in conventional masks such as sponge bodies, or a multilayer structure in which a plurality of layers are laminated alone or in an appropriate combination,
Alternatively, it can be formed as a single layer,
Activated carbon or another appropriate functional material layer may be interposed or added between the laminated structures or at an appropriate position on the inner surface as needed, for example, to enhance the filter effect.

The mask main body is provided with ear hook portions on the left and right side edges thereof so as to penetrate vertically, so that an annular ear hook can be inserted, or the ear hook portions are provided. Instead, one end of the string-shaped ear hook is sewn to the upper end of each of the left and right side edges, and the other end is sewn to the lower end to form a substantially annular ear hook. However, the setup for attaching the ear hook is not particularly limited, and it is assumed that the ear hook is previously attached to the mask main body by the above-described means, and a thin film band described later is sewn to a predetermined portion of the mask main body by other means. After being integrated with, or integrated with the thin film band,
It suffices if it is performed at the optimal stage in the hygiene mask manufacturing process.

[0013] The thin film-like band is integrated so as to protrude upward over the entire width of the upper end edge of the mask main body, dive inside the eyeglasses at the time of wearing, is pressed against the lower edge of the eyeglass frame, and is placed on the cheek. By tightly fitting around, it functions so as not to leak exhaled air from at least the upper side, that is, the eyeglasses side, from the gap formed at the upper edge of the mask main body from the nose wings to the cheek. Things,
In relation to the face to be located, the central portion corresponds to a position beyond the back of the nose, and it is necessary to surely prevent the exhalation from rising from that portion. The left and right sides of the part are around the upper cheekbones (about 1c from the eye)
m below), the upper edge contour is formed so that it is formed on the hem with a gentle slope so as to be slightly above the lower edge of the eyeglass frame as desired. As a result, the mask is formed in a substantially linear shape so as to be integrated with the upper end edge of the mask body. As a result, the overall planar shape (the front shape in the worn state) has a rounded upper side portion of the horizontally long “convex” character. The upper and lower widths at both skirts are approximately half of the distance from the human eye to the nasal wing. (Projecting parts) must be regulated.

When the thin-film strip is worn integrally with the upper end edge of the mask body, the ridge is adapted to the convex shape of the back of the nose, and the left and right hem portions are pressed by the lower edge of the glasses frame. In order to adhere closely to the shape around the cheekbone, a thin elastic material such as silicone resin, polyethylene resin, vinyl chloride resin, elastomer resin, rubber, etc. It should be made of a transparent or translucent material so that it is as inconspicuous as possible at the stage, and should be integrated by suture, bonding or other known appropriate means over the entire width of the upper edge of the mask body at the remaining lower edge where the upper and lower effective width is secured Be transformed into

Further, this thin film-shaped strip is provided with side membrane portions having a length corresponding to the vertical dimension of the mask body extending downward from both end portions of the lower end edge thereof, and has a substantially gate-shaped planar shape. The two sided film portions are also integrated with the inner side of the mask body slightly inside from the left and right side edges of the mask main body, and the vertical outer edge of each side film portion is included. (Left outer edge for the left side membrane, right outer edge for the right side) Keep the side away from the mask body, and prevent the shrinkage of the left and right side edges of the mask body as much as possible by pulling the ear hook If it shrinks somewhat or breaks in the shape of a `` ku '', each vertical outer edge that is separated from the mask body may follow the deformation of the left and right side edges of the mask body. Without deforming in a slightly independent state Becomes planar contact to (the cheek around), it would serve to occlude as possible liable to occur gap to the mask body right and left side edges.

It should be noted that this thin-film strip may be based on the above-described structure and may also have some other additional structures. In order to make it easy to deform according to the unevenness of the face, the thickness of the required part is made thin (relatively thicker in other parts) or cut out,
Alternatively, in order to enhance the adhesion effect, the main part is enlarged so that a part of the outer surface is pressed by the ear hook, and it is advantageous for packaging when commercializing, and it is also convenient for the user to carry. A fold line (thin part or cut) that can bend the part protruding from the mask body inward for the purpose of making it more convenient and also allowing people other than spectacle users to use it without discomfort. The configuration can be added as appropriate, for example. In the following, the configuration of the sanitary mask of the present invention described above can be more clearly understood,
Some examples representing the sanitary mask of the present invention will be taken up, and specific description will be added.

[0017]

Embodiment 1 An exploded perspective view of FIG. 1, an overall perspective view of FIG. 2 in which they are integrated into a sanitary mask of the present invention, and a perspective view showing a use mode of FIG. It is a typical example of a sanitary mask having a basic configuration. Gauze, bleached cotton and other thin cloths are folded several times to form a rectangular body of appropriate size, and the inside of about 1.5 to 2 cm from both right and left edges is vertically sewn, respectively.
It is assumed that the annular ring-shaped ear hooks 11 and 11 are inserted through the respective ear hook-through portions outside the seams 12 and the mask body 1
To form

On the other hand, the thin film-shaped band 2 has a mountain portion 21 at the center of the upper end edge thereof, and gently connected hem portions 22, 22 on both sides thereof. The upper and lower effective widths 22h shown in FIG. 1 are set to approximately 2 cm, and the upper surface of the mask main body 1 at the position slightly lower than the upper effective width 22h shown in FIG. The suturing 3 is integrated, and the thin film strip 2 in a state where an upper and lower effective width 22h is secured above the upper edge of the mask body 1 as shown in the perspective view of FIG.
Are formed on the sanitary mask of the present invention, which is integrated in a protruding manner.

[0019]

Embodiment 2 The embodiment shown in the longitudinal sectional view of (1) in FIG. 4 and the enlarged longitudinal sectional view of the main part of (2) in which the guide circle portion in the figure is enlarged is shown in FIG. The thin film strip 2 formed in the same manner has a cut 25 formed over the entire width of the front side (the side facing the mask main body 1) at a position slightly higher than the seam 3 with the mask main body 1. A representative example of a sanitary mask in which the upper and lower effective width portions of the thin film strip 2 can be folded inward from the cut 25 and folded inside the mask body 1 is described.

The folding structure may be formed by forming a thin portion at the same place besides the cut 25 of the embodiment,
Alternatively, it must be a structure that was previously bent at the same place,
Various types of structures, such as those used by forcibly expanding them at the time of wearing and returning them to a flat plate shape or a state close thereto, are included. In the case of the sanitary mask of the illustrated embodiment, the cross section of the upper end contour side of the thin film-shaped band 2, that is, the side in contact with the face has a gradually thinner structure, and the familiarity with the face is better. I am trying to become.

[0021]

Embodiment 3 In the example shown in the horizontal sectional view of FIG. 5A and the vertical sectional view of A-A of FIG. 5B, the portion corresponding to the peak 21 of the thin film-like band 2 is a skirt. This is a typical embodiment in which the skirt portions 22 and 22 are formed to be thinner than the skirt portions 22 and 22 and are easily deformed along the nose and back that protrudes most from the face. Even if the top side of the upper edge is held down by the lower edge of the eyeglass frame, it fits well into the convex shape of the back of the nose and deforms so that it can be worn without forming any gaps on both sides of the back of the nose. It is.

[0022]

[Embodiment 4] The embodiment shown in the horizontal sectional view of FIG. 6 is also similar to the embodiment 3 described above, and is another embodiment relating to the close contact structure between the ridge 21 of the thin film band 2 and the back of the nose when worn. In the embodiment, the portion is thinned to facilitate the deformation from the flat plate-like structure. It is a typical example of what is molded into a protruding shape corresponding to the part shape, so that it can respond to the shape of the back of the nose that changes depending on the wearer, with a slightly smaller protruding shape, in some cases, as in the above example It is convenient if it is formed in a thin protrusion shape.

[0023]

[Embodiment 5] The plan view of FIG. 7 shows another embodiment of the thin film-shaped band 2, in which the portion formed as in Embodiment 1 is the main part, and the hem 22, Each of the side film portions 23 having a length substantially the same as the vertical size of the mask main body 1 and a width of about 2 to 2.5 cm is provided at each end of the lower edge of the mask 22.
This is an example in which 23 are connected and integrated to form a thin film-like band 2.

The continuous boundary region between the lower end portions of the main portion of the thin film strip 2 and the side film portions 23, 23 is formed by cut portions 24, 24 cut out in an outward V-shape. The main portion including the portion 21 and the hem portions 22 is sewn 3 to the upper end edge of the mask body 1 at a portion slightly below the portion where the vertical effective width is secured, and the side membrane portions 23 Are sewn together with the sewn portion 12 for the ear hook-through portion of the mask body 1 so as to be integrated with the inside of the mask body 1.

When the upper end of the ear hook 11 is pulled during the wearing stage, and the hem portions 22, 22 are deformed to be attached to the vicinity of the cheekbones, the cut portions 24, 2 are formed.
4, the side film portions 23, 23 can maintain the independence as much as possible without following the deformation thereof, and can cope only with the vertical deformation of the left and right end portions of the mask main body 1. And the side membrane portions 23, 23 not sewn to the mask body 1
Of the mask body 1 is almost independent of the deformation of the left and right ends of the mask body 1 and is almost independently deformed so that it can be deformed to the cheek side, and tends to occur on the left and right ends of the mask body 1. It is intended that the gap can be closed as much as possible.

[0026]

Sixth Embodiment A sanitary mask shown in the perspective view of FIG. 8 is another embodiment which is common to the above-mentioned sixth embodiment in its basic components. Both are formed to have an external appearance that is hidden inside the mask body 1, whereas in this embodiment, the crest 21 and the two skirts 22,
22 and protrude outward from both ends of the main part,
The mask body 1 is integrated so that it can be seen from the outside of the left and right side edges. As can be understood from FIG. Since the upper and lower end surfaces of the exposed side film portions 23, 23 are pressed against the face side, even if the mask body 1 has a gap on both left and right side edges thereof, the both side film portions 23 will not be pressed. , 23 substantially closes the gap, thereby realizing a safer hygiene mask.

[0027]

The sanitary mask of the present invention having the above-mentioned structure is particularly effective for spectacle users, and is applied to the ears of the wearer who has already indicated the spectacle vine, like the conventional mask. After wearing with the both ears 11, 11, the peak 21 of the thin film-like body 2 protruding upward from the upper edge of the mask body 1 is adjusted to a position just beyond the nose, and both hem 22, 22 is a spectacle frame or spectacle lens G
When the eyeglasses G are slightly shifted upward so as to enter the inside of the lower edge of the eyeglass 1 and then returned to the original posture, the lower edge of the eyeglass frame or the eyeglass lens G1 becomes
As a result, the thin film-shaped band 2 has its peak 21 in close contact with the back of the nose, and the two skirts 22, 22 connected to both sides of the thin band 2 subsequently follow. It becomes tightly attached around the cheekbones, and is worn with almost no gap between the thin film band 2 and the face.

Further, the thin film strip 2 is formed by the side film portions 23,
In the case of a structure in which 23 are continuously provided, each outer vertical edge side is almost independent of deformation of the mask main body 1 and deforms substantially independently, and tends to occur on the left and right sides of the mask main body 1. The gap is substantially closed, and the invasion of outside air from both the left and right sides of the mask body 1 is prevented as much as possible, and the sutures 12, 12 are integrated with the mask body 1 of the side membrane portions 23, 23. Due to the structure, even when worn for a long time, the left and right side portions of the mask body 1 can be kept in a state in which the left and right side portions are hardly deformed in the vertical direction or deformed in the shape of a ku, and the function as a mask is maintained. Thus, the function of stabilizing the wearing form is achieved.

[0029]

According to the sanitary mask of the present invention,
Even if worn by spectacle wearers, the exhaled breath exhaled inside the mask body is blocked by the mask body made of a relatively fine-grained material and the internal pressure increases, resulting in a movement like a rising airflow. At the top edge of the mask body, even if you try to escape upward from the gap around both nose wings, which is inevitable from the shape of the protruding face of the nose tip, the thin film band is pressed by the lower edge of the eyeglass frame or eyeglass lens. Since it is in close contact with the face in a stable state and hardly leaks to the upper side, that is, to the spectacle lens side, the spectacle lens does not fog at all like the conventional one, Since it is possible to wear a mask in the same condition as a person who is not using it, it is possible to prevent influenza, prevent infection to others, or If there is a need to prevent hay fever that causes severe symptoms, or to avoid dust in dirty air, there is no need to hesitate and there is no need to care about the direction of exhalation exhaled in the mask Therefore, it is possible to obtain an extremely excellent feature that it can be easily worn.

Further, in the case of a sanitary mask in which a thin film strip having a structure in which the side membrane portions are continuously provided, in addition to the above-described features, the confidentiality of the left and right sides of the mask main body is also reduced to the conventional one. By comparison, it is much more excellent, and the original function as a hygiene mask can be reliably achieved, and extremely safe masks can be realized according to various purposes and applications. Even if you keep on wearing for a long time, the wearing form like the previous one collapses, the risk of deteriorating the appearance can be greatly reduced, and the big feature that it is possible to realize a sanitary mask with good practicality It can be demonstrated.

In particular, in the embodiments shown in the embodiments, the above-mentioned effects can be achieved uniformly, and in the embodiment shown in the second embodiment, it is assumed that the products are excellent in commercialization and portability. In addition to this, it is possible to obtain an advantage that it is possible to wear the same mask appearance as before as well as a spectacle user, except for the spectacle user.
Can easily adapt to the nose column at the time of wearing, the effect of preventing exhalation of air from leaking from the same place can be further enhanced, and at the same time, the feeling of discomfort during wearing can be reduced. In addition to the effect of preventing eyeglass lens fogging, the effect that the original mask of the outside air is blocked more reliably and the effect of reducing the shape collapse when wearing it will be obtained. Thus, the usefulness of realizing a sanitary mask with even higher practical value is exhibited.

As described above, the sanitary mask of the present invention can attain the intended purpose from the above-mentioned characteristic and novel construction, and therefore, it is a conventional sanitary mask especially for eyeglass users. Compared to conventional masks, not only in terms of its function, but also in terms of manufacturing, use, etc., it has been significantly superior in all respects, and in Japan, the number of eyeglass users is very large compared to other countries , Its effectiveness is highly evaluated and it is expected that it will be widely used and used.
