Description

The present invention relates to a three-dimensional mask covering a target portion of the face including the mouth and nose of a user, and particularly to a three-dimensional mask configured so that a facial region including the mouth can be seen through.

Conventionally used cloth and non-woven masks are generally ear-hook masks that cover the nose and mouth, but since the movement of the mouth is hidden, the user's facial expression cannot be read accurately, which hinders communication. In some cases. Therefore, the following masks have been proposed to solve this problem.

Patent Documents 1 to 4 disclose a three-dimensional mask in which a three-dimensional shield capable of seeing through the face is formed of a non-breathable transparent resin, and a breathing portion made of a non-woven fabric or the like is integrated under the three-dimensional shield. In any of the configurations, the mask is attached to the face by the ear hooks attached to the left and right edges of the resin three-dimensional shield. The vent is bonded to the lower edge of the three-dimensional shield.

On the other hand, Patent Documents 5 and 6 disclose a three-dimensional mask composed entirely of a transparent breathable sheet.

Japanese Unexamined Patent Publication No. 2009-11475 Japanese Unexamined Patent Publication No. 2009-189676 Japanese Unexamined Patent Publication No. 2013-046647 Japanese Unexamined Patent Publication No. 2013-169346 Japanese Unexamined Patent Publication No. 2007-021026 Japanese Unexamined Patent Publication No. 2013-06643

In the three-dimensional mask disclosed in Patent Documents 1 to 4, the non-woven fabric or the like constituting the ventilation portion is adhesively bonded to the three-dimensional shield, but once the adhesion is broken due to a load such as an external force, the three-dimensional shield is bonded at that position. There is a problem that the inner space directly communicates with the outside air, and the shielding effect against the scattering and suction of droplets is easily impaired. Further, in the section of the peripheral edge of the three-dimensional shield where the ventilation portion is not connected, a large gap is likely to be formed between the peripheral portion and the face, which also contributes to the deterioration of the shielding effect. Another problem is that the ventilation part and the three-dimensional shield are integrated, and the ear hook part is also provided on the three-dimensional shield. Therefore, if the ventilation part deteriorates due to repeated use, the three-dimensional shield must be replaced with a new one. It must be uneconomical. Further, in the state where the hard three-dimensional shield and the highly flexible ventilation portion are integrated, there is a problem that it is very difficult to perform cleaning for reuse. For this reason, the above-mentioned three-dimensional mask has not been widely used.

The transparent breathable material constituting the three-dimensional mask disclosed in Patent Documents 5 and 6 is expensive, and the air permeability suitable for use as a mask (for example, the method specified in JISZ0208) as long as the opening is not considerably roughened. It is not possible to secure a water permeability of 300 g / m ² · hr or more as measured in, and as a result, it is not possible to secure sufficient shielding properties as a mask, so the current situation is that its use is limited to ideas. Is.

The subject of the present invention is that it has a fluoroscopic structure to the extent that the facial expression of the user can be sufficiently confirmed, and while ensuring good air permeability, it also has excellent shielding properties against splashing and inhalation, and can be reused. It is an object of the present invention to provide a three-dimensional mask having a structure that is easy to perform cleaning and the like.

In order to solve the above problems, the three-dimensional mask of the present invention is made of a transparent polymer material in which the inner surface is a concave surface forming a mounting surface on the user's face and the outer surface is a convex surface corresponding to the concave surface. A first body consisting of a thin-walled molded body that covers at least the mouth of the user and covers the out-of-range first lower face area and forms a breathing space between the inner surface and the first lower face area. The second lower face region and the first main body are detachably configured on the outside of the first main body by a breathable flexible sheet member, and are outside the first lower facial region and both eyes are out of range. The second main body and the second main body are formed with a see-through penetrating portion for exposing the portion other than the peripheral portion of the first main body as a see-through area for seeing through the user's mouth. A pair of ear hooks provided on both the left and right edges of the main body is provided, and by attaching the ear hooks to both ears of the user, the back surface of the edge of the see-through penetration portion of the second main body is first. By crimping it to the outer surface of the peripheral edge of the main body, the first main body is pressed against the user's face to force it, and the peripheral edge of the first main body covered by the breathable second main body has a breathing space and the first main body. It is characterized in that a breathing communication portion is formed to communicate with the space covered by the second main body on the outside of the.

The three-dimensional mask of the present invention has a first main body made of a thin-walled molded body made of a transparent polymer material to be attached to the user's face, and a breathable flexible sheet member attached to and detached from the outside of the first main body. It consists of a second body consisting of. The second main body has a see-through penetration portion, and the first main body is fitted into the protruding portion so as to be exposed, and in that state, the first main body is applied to the user's face together with the second main body to form the second main body. Attach the provided ear hook to your ear. The area of the lower part of the first face where the penetration part for fluoroscopy is exposed is the area including at least the user's mouth, and both eyes are not covered by either the first body or the second body. It is possible to check the facial expression of the face. On the other hand, a breathing communication part is formed on the peripheral edge of the first main body, and the inner breathing space is ventilated by the breathing communication part, and the breathable second main body (penetration for see-through) is provided above the breathing communication part. Since the edge along the portion is covered, a mask structure that has both good air permeability to the breathing space and good shielding property against splashing and inhalation is realized. Further, by attaching the ear hooks provided on the second main body to both ears of the user, the back surface of the edge of the see-through penetration portion of the second main body is crimped to the outer surface of the peripheral edge of the first main body, and the first Since the main body is pressed against the user's face and urged, both the close contact between the first main body and the face and the close contact between the first main body and the second main body at the position of the breathing communication part are improved, and the above shielding Further contribute to improving sex.

On the other hand, since the first main body made of a transparent polymer material and the second main body made of a breathable flexible sheet member are separated from each other, one of the first main body and the second main body has deteriorated. In that case, it is economical because only the deteriorated one can be replaced and the other can be reused. In addition, since the second main body for ensuring breathability and the first main body for seeing through the mouth etc. are separated from the beginning, there is no concern that the bond between the two will be broken due to damage from the beginning. .. Further, cleaning for reuse can be performed individually for the first main body and the second main body, which has an advantage that cleanliness can be easily maintained.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
(Embodiment 1)
FIG. 1 is a front view showing a three-dimensional mask 1 forming the first embodiment of the present invention in a mounted state, and FIG. 2 is a side view as well. Further, FIG. 3 is a front view showing the details of the first main body, and FIG. 4 is a side view as well. The three-dimensional mask 1 includes a first main body 10 and a second main body 20, and a pair of ear hooks 3 provided on both left and right edges of the second main body 20.

As shown in FIGS. 3 and 4, the first main body 10 is a transparent polymer whose inner surface is a concave surface forming a mounting surface of the user BG on the face and whose outer surface is a convex surface corresponding to the concave surface. It consists of a thin-walled molded body of material. The first main body 10 includes the mouth and nose of the user BG, covers the first lower facial region where both eyes are out of range, and forms a respiratory space AS between the inner surface and the first lower facial region. .. The transparent polymer material is a thermoplastic transparent resin material such as polyethylene terephthalate resin, polycarbonate resin, acrylic resin and polystyrene resin, and the first main body 10 is formed by injection molding or blow molding of these resins. As shown in FIG. 4, a hydrophilic anti-fog layer CT containing silica and a surfactant may be formed on the inner surface of the first main body 10.

Further, as shown in FIGS. 1 and 2, the second main body 20 is configured to be detachably attached to the outside of the first main body 10 by a flexible sheet member having breathability. The second main body 20 covers the outer side of the first lower face region and the second lower face region outside the range of both eyes together with the peripheral portion of the first main body 10. Further, the second main body 20 is formed with a see-through penetrating portion 21 for projecting and exposing a portion other than the peripheral portion of the first main body 10 as a see-through region for seeing through the mouth of the user BG.

The material of the breathable flexible sheet material constituting the second main body 20 can be appropriately determined. For example, the moisture permeability measured by the method specified in JISZ0208 is 300 g / m ² · hr. The above-mentioned breathable material can be used. Examples of such a material include woven fabrics such as cotton cloth and gauze, short fiber or long fiber aggregates such as non-woven fabric, and laminated bodies obtained by laminating a plurality of layers thereof. When a fiber aggregate is used, what the raw material fiber is is not particularly limited, but for example, synthetic fibers made of olefin-based fibers such as polyethylene and polypropylene, polyester-based and polyamide-based thermoplastic resins, rayon, cupra and the like. Examples thereof include recycled fibers, natural fibers such as cotton, and mixed fibers in which two or more of them are used. When a fiber aggregate is used, the basis weight can be, for example, 15 to 70 gsm, particularly 20 to 50 gsm.

When a non-woven fabric is used, it may be manufactured by any processing, and for example, known methods such as a spunlace method, a spunbond method, a thermal bond method, a melt blown method, a needle punch method, and an air through method are known. Can be exemplified by the product manufactured by the above method. Further, in order to enhance the blocking performance of pollen and fine dust, a laminated non-woven fabric having a layer made of ultrafine fibers (diameter 0.5 μm or more and 5 μm or less) such as SMS non-woven fabric or SMMS non-woven fabric can be used.

Further, the ear hook portion 3 is composed of a flexible linear member having elasticity such as a rubber string. The ear hook portion 3 can be formed by joining both ends of the second main body 20 separately from the second main body 20 to the left and right edges of the second main body 20 by a known means such as suturing or thermocompression bonding. On the other hand, the ear hook portion 3 may be integrally formed with the second main body 20 by using the same material as the second main body 20.

In the three-dimensional mask 1, by attaching the ear hooks 3 to both ears of the user BG, the back surface of the edge portion of the fluoroscopic penetration portion 21 of the second main body 20 is crimped to the outer surface of the peripheral edge portion of the first main body 10. The first main body 10 is attached by pressing it against the face of the user BG and urging it. Then, on the peripheral edge of the first main body 10 covered by the breathable second main body 20, a breathing communication portion for communicating the breathing space AS and the space covered by the second main body 20 outside the first main body 10 11, 11B are formed.

The three-dimensional mask of the present invention has a first main body 10 made of a thin-walled molded body made of a transparent polymer material to be attached to the face of the user BG, and a flexible flexible one attached to and detached from the outside of the first main body 10. It is composed of a second main body 20 made of a sex sheet member. The second main body 20 has a see-through penetration portion 21, in which the first main body 10 is fitted so as to be exposed in a protruding form, and in that state, the first main body 10 is fitted to the face of the user BG together with the second main body 20. The ear hook portion 3 provided on the second main body 20 is attached to the ear.

When promoting smooth communication through conversation, it is extremely important to read emotions such as whether the other person is laughing, angry, or sad from the facial expression. However, with a general mask, the user's mouth is hidden by wearing it, and it is very difficult to correctly read the user's emotions only from the unhidden eyes. However, as shown in FIG. 1, according to the three-dimensional mask 1, the first facial lower part region where the fluoroscopic penetration portion 21 is exposed is a region including at least the mouth of the user BG, and both eyes are the first main body 10 and the region. It is not covered by any of the second main body 20. That is, since the mouth can be seen through the first main body 10, it is possible to sufficiently confirm the facial expression of the user BG and, by extension, the emotion.

On the other hand, a breathing communication portion 11 is formed at the peripheral edge of the first main body 10, and ventilation is secured by the breathing communication portion 11 in the inner breathing space AS. The structure is such that the breathable second main body 20 (the edge along the fluoroscopic penetration portion 21) covers the top thereof, so that the breathing space AS has good breathability and good resistance to splashing and inhalation. It is possible to achieve both excellent shielding properties. Further, by attaching the ear hooks 3 provided on the second main body 20 to both ears of the user BG, the back surface of the edge portion of the fluoroscopic penetration portion 21 of the second main body 20 is the outer surface of the peripheral edge portion of the first main body 10. Since the first main body 10 is pressed against the face of the user BG and urged, the first main body 10 and the second main body 20 are in close contact with the face and the breathing communication portion 11 position. Both of the adhesion and the adhesion of the above are improved, which further contributes to the improvement of the above-mentioned shielding property.

On the other hand, since the first main body 10 made of a transparent polymer material and the second main body 20 made of a breathable flexible sheet member are separated from each other, the first main body 10 and the second main body 20 are separated from each other. When one deteriorates, it is economical because only the deteriorated one can be replaced and the other can be reused. In addition, since the second main body 20 for ensuring air permeability and the first main body 10 for seeing through the mouth and the like are separated from the beginning, there is a concern that the bond between the two will be broken due to damage from the beginning. not exist. Further, cleaning for reuse can be performed individually on the first main body 10 and the second main body 20, which has an advantage that cleanliness can be easily maintained.

Hereinafter, the geometrical features of the three-dimensional mask 1 will be described in more detail. As described above, the three-dimensional geometric expression in the explanation shall be described in the state of being worn by the user unless otherwise specified, and the vertical direction of the face is defined as the vertical direction and the width direction of the face is defined as the horizontal direction. do. As shown in FIGS. 1 and 2, the first lower face region covered by the first main body 10 also includes the nose of the user BG, and the facial expression of the user BG through the fluoroscopic penetration portion 21. It is easier to check.

Further, the see-through penetration portion 21 is formed in an annular shape, and the second main body 20 is formed so as to cover the entire peripheral edge portion of the first main body 10. Therefore, even if there is a section on the periphery of the first main body 10 where a gap is generated between the first main body 10 and the face, the breathing space AS always has a structure that communicates with the external space via the second main body 20, and the shielding property is further improved. Has been done.

As shown in FIGS. 3 and 4, in the section of the outer peripheral edge of the first main body 10 that comes into contact with the face of the user BG, a pad portion 12 made of an elastic material softer than the transparent polymer material, for example, silicone rubber, is formed. It is integrated along the outer peripheral edge, and the adhesion of the outer peripheral edge portion of the first main body 10 to the face is enhanced.

Next, as shown in FIGS. 1 and 2, a linear elastic member 22 made of a rubber thread or the like is integrally incorporated in the fluoroscopic penetration portion 21 along the inner edge thereof. As shown on the right side of FIG. 5, the linear elastic member 22 has an inner side in which the inner edge forming portion of the fluoroscopic penetration portion 21 is wrinkled when the first main body 10 is removed from the fluoroscopic penetration portion 21. It becomes a contracted state together with the edge forming part. Then, in the state where the first main body 10 is attached to the fluoroscopic penetration portion 21, as shown on the left side of FIG. 5, the fluoroscopic penetration portion 21 is press-fitted and becomes an stretched state together with the inner edge forming portion. As shown in FIG. 5, the fluoroscopic penetration portion 21 is formed as a gather portion.

As shown in FIG. 8, the inner edge forming portion of the see-through through portion 21 is crimped and urged to the outer surface of the first main body 10 by the elastic return force of the linear elastic member 22 toward the contracted state. By providing such a linear elastic member 22, the edge portion of the second main body 20 along the fluoroscopic penetration portion 21 can be more firmly adhered to the first main body 10 (pad portion 12). In the configurations of FIGS. 1 to 4, the see-through through portion 21 and the linear elastic member 22 are each formed in an annular shape, and the state of close contact of the peripheral edge of the see-through through portion 21 with the first main body 10 is more uniform in the circumferential direction. It can be secured.

Next, as shown in FIGS. 3 and 4, the breathing communication portions 11 and 11B are formed as through holes penetrating the first main body 10 in the thickness direction. The breathing communication portions 11 and 11B having such a shape are easy to form. As shown in FIG. 7, the breathing communication portion 11 is formed as a notch portion that opens to the outer peripheral edge of the first main body 10. By forming such a notch, communication between the breathing space AS and the external space can be easily achieved even at the outer peripheral edge of the first main body 10 in contact with the face of the user BG.

Further, the breathing communication portion 11B formed at the lower edge portion of the first main body 10 is also a notch portion as shown in the arrow view of D in FIG. Even when water droplets adhere to the inner surface of the first main body 10, the water droplets can be easily discharged downward from the breathing communication portion 11B. Further, the breathing communication portion 11B is also covered with the second main body 20. As a result, the water droplets are absorbed or blocked by the second main body 20, and the water droplets are prevented from flowing down toward the jaw.

As shown in FIGS. 4 and 7, the pad portion 12 attached to the outer peripheral edge of the first main body 10 is interrupted in the forming region of the breathing communication parts 11 and 11B, and the breathing communication parts 11 and 11B are interrupted. The open side of the notch portion of 11B is directly partitioned by the facial FP. In particular, for the breathing communication portion 11B, water droplets that are not obstructed by the pad portion 12 can flow down.

Further, as shown in FIGS. 3 and 4, the first main body 10 has a ridge portion 13 for forming a ventilation assisting groove communicating with the breathing space AS on the mounting surface side so as to project toward the outer surface side. It is formed, and a breathing communication portion 11 is formed in the convex portion 13. Then, a part of the convex portion 13 including the forming region of the breathing communication portion 11 is covered with the second main body 20. By forming the ventilation auxiliary groove by the convex portion 13, the cross-sectional area of the ventilation path leading to the breathing communication portion 11 can be expanded, and smoother breathing becomes possible.

The breathing space AS becomes narrower as it approaches the outer peripheral edge of the first main body 10 in contact with the face of the user BG. The ridge portion 13 is formed so that the first end portion is located on the outer peripheral edge side of the first main body 10 and the second end portion is located on the central side of the first main body 10, and the breathing communication portion 11 is first. It is designed to be formed at the end. Even if the breathing communication portion 11 is formed in the vicinity of the outer peripheral edge of the first main body 10, the ridge portion 13 can sufficiently secure the ventilation cross-sectional area.

In the present embodiment, the convex portion 13 having the first end located on the left cheek or the right cheek side of the user BG and the second end located on the nasal side is distributed to the left and right sides of the first main body 10. A plurality of, specifically, a set of three protrusions 13 arranged in the vertical direction are formed on both the left and right sides. As a result, a plurality of breathing communication portions 11 as outside air intake ports are opened in the vicinity of both the left and right cheeks, and it is possible to efficiently guide the outside air toward the mouth or nose at the center of the first main body 10.

As shown in FIG. 3, the auxiliary communication portion 18 can be formed in a penetrating form in the region exposed in the fluoroscopic penetrating portion 21 of the first main body 10. With such an auxiliary communication portion 18, the circulation of outside air to the breathing space AS becomes better, but there is a trade-off in the blocking effect of droplets and the like. For example, in order to reduce the influence of the invasion of droplets through the auxiliary communication portion 18 and the emission of the droplets emitted by the user from the other party in the meeting, the auxiliary communication portion 18 is removed from the user's mouth or nose. It is desirable to form it in a position. In FIG. 3, the auxiliary communication portion 18 is formed as a plurality of through holes dispersedly formed below the user's mouth.

(Embodiment 2)
FIG. 9 shows the three-dimensional mask 100 according to the second embodiment of the present invention (the same reference numerals are given to the common points with the three-dimensional mask 1 of FIG. 1, and detailed description thereof will be omitted). In the three-dimensional mask 100, a plurality of breathing communication portions 111 are formed at predetermined intervals so as to surround the mouth of the user BG along the outer edge of the first main body 110. With this configuration, the outside air can enter and exit from various directions from the breathing communication portion 111 surrounding the mouth around the mouth where the user BG breathes, and the air permeability to the breathing space AS can be significantly improved. can.

The plurality of breathing communication portions 111 are arranged in an annular shape along the outer peripheral edge of the first main body 110. Further, as shown in FIG. 10, an annular groove 14 for fitting a linear elastic member 22 provided in the second main body 20 inside the annular arrangement of the breathing communication portions 111 on the outer surface of the first main body 110. Is formed. By fitting into the annular groove 14, the position of the linear elastic member 22 is stably held inside the plurality of breathing communication portions 111, and the plurality of breathing communication portions 111 are the annular fluoroscopic penetration portions of the second main body 20. It is possible to maintain a good state of being completely covered by the peripheral region of 21. In FIG. 9, the linear elastic member 22 has a structure sewn to the peripheral edge of the fluoroscopic penetration portion 21 of the second main body 20 by a slightly thick rubber string.

As shown in FIG. 10, the first main body 110 has a convex central main portion 15 and a ring-shaped first outer peripheral wall integrated via an annular groove 14 so as to extend laterally from the peripheral edge thereof. The portion 16 has a tubular second outer peripheral wall portion 17 that descends from the outer peripheral edge of the first outer peripheral wall portion 16 toward the face FP of the user BG, and the plurality of breathing communication portions 111 are first. The outer peripheral wall portions 16 are formed at substantially equal intervals in the circumferential direction. It should be noted that a plurality of breathing communication portions 111'can also be formed at predetermined intervals on the cylindrical second outer peripheral wall portion 17. As a result, the air permeability of the first main body 110 to the breathing space AS can be further enhanced.

(Embodiment 3)
FIG. 11 shows the three-dimensional mask 200 according to the third embodiment of the present invention. The three-dimensional mask 200 is the same as the three-dimensional mask 100 (FIGS. 9 and 10) of the second embodiment except for the structure of the first main body 210. In the first main body 210 of the three-dimensional mask 200, the formation of the breathing communication portion 111 is omitted, and instead, the breathing communication portion 211 is formed in the form of notching the left and right side edges. As shown in FIG. 12, the breathing communication portion 211 forms a slightly wide notch in a bow shape with the facial FP, which is convenient for expanding the circulation cross-sectional area of the outside air. Further, similarly to the three-dimensional mask 1 of FIG. 1, a breathing communication portion 11B forming a notch is also formed on the lower edge portion of the first main body 210. Also in the three-dimensional mask 200 of this embodiment, in the region where the breathing communication portion 211 is not formed, the breathing communication to the first outer peripheral wall portion 16 or the second outer peripheral wall portion 17 is the same as that of the second embodiment. The portion 111 (or the breathing communication portion 111') may be formed.

(Embodiment 4)
FIG. 13 shows the three-dimensional mask 300 according to the fourth embodiment of the present invention, and FIG. 14 shows an enlarged view of the first main body 310 thereof. In the three-dimensional mask 300, the fluoroscopic penetration portion 321 is formed in a notched shape (or U-shape) in which the upper edge side is open with respect to the second main body 320. As a result, the area of the area covered by the second main body 320 on the upper part of the first main body 310 is reduced, and it becomes easier to visually recognize the facial expression of the user BG. The linear elastic member 322 also has an endped shape corresponding to the see-through through portion 321. The formation form of the ridge portion 13 and the breathing communication portions 11 and 11B is substantially the same as that of the three-dimensional mask 1 of the first embodiment (FIG. 1 and the like).

Of the outer peripheral edge of the first main body 310, the section exposed to the notch opening side of the see-through penetration portion 321 (that is, the section forming the upper edge of the first main body 310) has elasticity softer than that of the transparent polymer material. A pad portion 312 made of a material is integrated along the outer peripheral edge. Further, in the above configuration, since the pad portion 312 is provided on the upper edge (including the peripheral edge) of the first main body 310 which is not covered by the second main body 320, the deterioration of the shielding property in the section is effectively suppressed. ..

Since the see-through penetration portion 321 is open to the upper edge side of the second main body 320, when the second main body 320 is attached to the face by the ear hook portion 3, the upper part of the second main body 320 is left and right as it is. It opens wide and cannot induce a tension force to urge the first main body 310 on the face. Therefore, in the present embodiment, as shown in FIG. 13, the upper left and right ends of the fluoroscopic penetration portion 321 are connected to each other by the string-shaped connecting portion 323 so that the above-mentioned tension force can be secured.

(Embodiment 5)
FIG. 15 shows the three-dimensional mask 400 according to the fifth embodiment of the present invention. The three-dimensional mask 400 is substantially the same as the three-dimensional mask 300 of the fourth embodiment (FIG. 13 and the like), but the connecting portion 323 is abolished, and instead, the left and right upper edge positions of the see-through penetration portion 321 in the notched form are replaced. Corresponding to, the detachable coupling portion 30 is provided. The detachable coupling portion 30 detachably connects the inner surface of the second main body 320 to the left and right upper edge positions of the outer surface of the first main body 310, thereby providing a tension force for urging the first main body 310 to the face. It is designed to be induced. FIG. 16 is an example in which the detachable joint portion is formed by a well-known snap button. Further, FIG. 17 is an example in which the detachable coupling portion is formed by a well-known hook-and-loop fastener.

(Embodiment 6)
FIG. 18 shows the three-dimensional mask 500 according to the sixth embodiment of the present invention. The three-dimensional mask 500 has a region below the first face that covers only the area around the user's mouth, and has a first main body 510, a fluoroscopic penetration portion 521 of the second main body 520, and a linear elastic member 522.
