Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mask used in a place where dust is floating or where a chemical is used.

[0002]

2. Description of the Related Art Generally, a mask as shown in FIG. 5 is used when working or the like in a place where dust is floating. That is, this is a mask main body 30 formed by stacking a plurality of cotton gauze, and the mask main body 30.
And rubber bands 31 for ear hooks attached to both left and right sides of the. When using this mask, the nose and mouth are covered with the mask body 30, and the left and right rubber strings 31 are hooked on both ears and worn on the face.

[0003]

However, in this case, since the mask body is formed only by stacking several cotton gauze sheets, relatively large dust particles are collected by the cotton gauze sheet. However, there is a problem that fine dust penetrates. Moreover, this mask only covers the nose and mouth, and the eye is exposed while wearing it, so floating dust easily enters the eye, especially in places with strong winds or dust scattering. This is a high risk. On the other hand, the same mask as above is used for hygiene control etc. even in a place where chemicals are used, such as in a medical field, but even in this case, the conventional mask cannot protect the eye part. , There is a risk of eye contact if liquid or powdered chemicals are scattered.

The present invention has been made in view of such circumstances, and an object thereof is to provide a mask which can collect fine dust and at the same time protects an eye part.

[0005]

In order to achieve the above-mentioned object, the present invention forms a mask main body having a string-like body for ear hooks attached to both left and right sides thereof by a nonwoven fabric having a filtering effect, A plurality of folded portions extending in the lateral direction are formed in the central portion of the mask body, and a flexible transparent plate for covering the eye part is attached in a state of protruding upward from the upper end portion of the mask body. Take composition.

[0006]

That is, in the mask of the present invention, since the mask main body is formed of a nonwoven fabric having a filtering effect, this nonwoven fabric does not filter fine dust and absorb this dust into the body. In addition, since a plurality of folded portions extending in the lateral direction are formed in the central portion of the mask body, the nonwoven fabric forms folds at the folded portions, and when the outside air is filtered, dust contained therein is The filtration effect is enhanced by being concentratedly collected in the folds. Moreover, since the surface area of the non-woven fabric that contributes to the filtration is increased by the amount of forming the folds, the effect of collecting dust and the like is further increased and clogging is less likely to occur. Furthermore, when the folds of the folded portions of the above-mentioned plurality of strips are widened in the vertical direction, the central portion of the mask body extends, so it is easy to move the mouth even when talking while wearing the mask, and when the mouth is moved, the mask The body will not shift. In addition, a transparent transparent plate for covering the eye is attached to the upper end of the mask body so as to project upward. For this reason, since the transparent plate is located on the front surface of the eye part so as to cover the eye part in a state where the mask is worn, the floating dust is hard to enter the eye.
Particularly, in a windy place, the transparent plate acts as a windshield to prevent dust and the like from entering the eyes, and when dust or liquid scatters, the transparent plate acts as an eye protection plate. These are highly safe because they prevent them from entering the eyes.

Further, when the mask body is composed of three layers of non-woven fabric and the central non-woven fabric is formed more densely than the other two layers of non-woven fabric, the fine non-woven fabric is made into a finer material such as soot or soot. Dust will be collected. Further, in this case, since relatively large dust is collected in the non-woven fabric arranged on the front surface side, it is possible to prevent early clogging of the dense non-woven fabric in the center. Also, when antibacterial and deodorant properties are given to the back surface of the mask body, bacteria do not propagate to the saliva or the like that adheres to the mask body while wearing and does not give off a bad odor, and it is hygienic and used. It's comfortable. When a foldable linear body is attached to the upper edge of the mask body, the upper edge of the mask body can be bent from the nose bridge to the cheek spar by bending the linear body while wearing the mask. You will be able to follow the unevenness of the face over the face. Therefore, there is almost no gap between the mask body and the face, and dust and the like can be prevented from entering through this gap.

Next, the present invention will be described in detail based on embodiments.

[0009]

FIG. 1 shows an embodiment of the mask of the present invention. In this embodiment, the mask is the mask body 1
0 and a transparent plate 11 for covering the eye part. The mask body 10 is formed of a synthetic fiber non-woven fabric having a filtering effect, and is formed in a substantially square shape in a front view. The mask main body 10 includes a filtering portion 18 and crest portions 23 a, 2 provided on the outer peripheral portion of the filtering portion 18.
As shown in FIG. 2, the filtering part 18 is formed by stacking three layers of different types of non-woven fabrics. Of these, the second layer nonwoven fabric 21 arranged in the center has the densest tissue structure, and the third layer nonwoven fabric 20 arranged on the back side is subjected to antibacterial and deodorant treatment. In addition, the first layer nonwoven fabric 22 arranged on the front surface side is
The layers and the third layer non-woven fabrics 21 and 20 are formed to be slightly larger in the vertical direction, and in a state in which these layers are stacked in three layers, the predetermined width of the upper and lower ends is folded back to the back surface side, and this portion is
It is formed on the overlocking portions 23a and 23b. The upper and lower edge portions of the two overed portions 23a and 23b are heat-sealed in a chain line shape over the entire length (in the lateral direction of the mask body 10). Then, in the overhanging portion 23a located on the upper side of the mask main body 10, a bending portion formed in the bag-shaped portion formed in the gap between the upper and lower fusion-bonding portions 15 and extending in the lateral direction is slightly shorter than the lateral width of the mask main body. A flexible metal strip 13 is inserted. The filtering portion 18 includes
Three folded portions 14 extending in the lateral direction are formed in the central portion. The folded-back portion 14 is formed by bending the three-layered non-woven fabric so that the top portion 19 of the folds faces upward on the front side and downward on the rear side. On both the left and right sides of the filtering portion 18, a double-folded ear portion 24 formed of the same non-woven fabric as the first layer non-woven fabric 22 and a rubber string 12 for ear hooking are attached. The left and right edge portions of these two ears 24 are heat-sealed in a chain line shape over the entire length thereof (in the longitudinal direction of the mask body 10), and the both ends of the rubber cord 12 are bonded to the mask body by this fusion. It is fused and fixed to the upper and lower parts on both the left and right sides.

The transparent plate 11 is made of a synthetic resin and is formed into a flexible thin plate, and as shown in FIG. A notch 16 is formed in the center of the lower end side. Further, the surface of the transparent plate 11 is subjected to antifogging treatment. The lower ends of the transparent plate 11 at the left and right ends are fixed to the left and right ends at the upper side of the mask body by heat fusion. In the figure, reference numeral 17 is a fused portion.

Such a mask can be used, for example, as follows. That is, first, the mask body 10 is placed on the front of the face with the transparent plate 11 positioned on the upper side, the notch 16 of the transparent plate 11 is positioned on the bridge of the nose, and the nose and mouth are covered with the filtering portion 18. Next, the elastic cords 12 on both the left and right sides are hooked on the back side of both ears and attached to the face, and in that state, the band-shaped wire 13 at the upper edge of the mask body 10 is pressed from the front side to bend and the cheek girder from the nose bridge The gap between the mask body 10 and the face is eliminated along the unevenness of the face over the face. At this time, the notch 16 acts as a habit forming portion, the transparent plate 11 is curved along the face, and is positioned in front of the eye to cover the eye.

As described above, in the above-mentioned mask, since the mask body 10 is formed of the non-woven fabric having a filtering effect, the non-woven fabric does not filter fine dust and absorb the dust in the body. Further, since three folded portions 14 extending in the lateral direction are formed in the central portion of the mask body 10, the nonwoven fabric forms folds at the folded portions 14 and is included when outside air is filtered. Collected dust is concentratedly collected in the folds, and the filtering effect is enhanced. Moreover,
Since the surface area of the non-woven fabric that contributes to filtration is increased by the amount of forming the folds, the effect of collecting dust and the like is further increased, clogging is less likely to occur, and breathing is not difficult. Further, since the folds of the three folded portions are expanded in the vertical direction, the mask body will not be displaced even when the mouth is moved by talking or the like with the mask attached. Further, a transparent transparent plate 11 for covering the eye part is attached to the upper end of the mask body 10 so as to project upward. For this reason, since the transparent plate 11 is located on the front surface of the eye part so as to cover the eye part in a state where the mask is worn, the floating dust is hard to enter the eye. In particular, in a windy place, the transparent plate 11 acts as a windshield to prevent dust and the like from entering the eyes, and when dust or liquid scatters, the transparent plate 11 acts as an eye protection plate. Then, these are prevented from getting into the eyes, so they are excellent in safety. Further, since the transparent plate 11 is subjected to antifogging treatment on its surface, the transparent plate 11 will not be fogged by breathing or the like and the visibility will not be obstructed.

Further, in the above mask, the filtering portion 18 is
Since the second layer non-woven fabric 21 is formed more densely than the first layer non-woven fabric 22, the second layer non-woven fabric 21 collects finer dust such as soot or soot. become. Furthermore, in this case, the first placed on the front side
Since relatively large dust is collected by the layered nonwoven fabric 22, it is possible to prevent the dense second layer nonwoven fabric 21 from being clogged at an early stage. In addition, since the third layer nonwoven fabric 20 is provided with antibacterial and deodorant properties, bacteria are not propagated in the saliva or the like that adheres to the filtration portion 18 during wearing, and no bad odor is emitted, which is hygienic. Comfortable to use. Also, the mask body 1
Since the strip-shaped wire 13 is attached to the upper edge of the mask 0, the strip-shaped wire 13 is bent while the mask is worn, so that the upper edge of the mask body 10 conforms to the unevenness of the face from the bridge of the nose to the cheek girder. be able to. For this reason,
There is almost no gap between the mask body 10 and the face, and it is possible to prevent dust and the like from entering through this gap.

FIG. 4 shows another embodiment of the present invention. In this embodiment, the transparent plate 11 is formed in a shape in which both the left and right sides are convexly extended in the lateral direction. As a result, when the mask is worn, the transparent plate 11 is positioned not only on the front surface of the eye but also on the left and right side surfaces. Therefore, the dust is prevented from jumping in from the lateral direction and entering the eye, so that the protection of the eye portion is further enhanced. The other parts are the same as those in FIG. 3, and the same parts are denoted by the same reference numerals.

[0015]

As described above, in the mask of the present invention, the non-woven fabric of the mask body filters fine dust and does not absorb this dust into the body. Further, when the non-woven fabric forms a fold at the folded portion and the outside air is filtered, the dust contained therein is concentratedly collected in the fold and the filtering effect is enhanced. Moreover, since the surface area of the non-woven fabric that contributes to the filtration is increased by the amount of forming the folds, the effect of collecting dust and the like is further increased, clogging is less likely to occur, and breathing is not difficult. Further, when the mask is worn on the face, the folds of the folded portions are widened to form a recess in the central portion on the back side of the mask main body, and the protruding parts such as the lips and the nose are accommodated in the recess when the mask is worn. be able to. By doing so, the mask body will not be displaced even when the mouth is moved by talking or the like with the mask attached. Further, since the transparent plate is located on the front surface of the mask so as to cover the eye part in a state where the mask is worn, floating dust is less likely to enter the eye. Particularly, in a windy place, the transparent plate acts as a windshield to prevent dust and the like from entering the eyes, and when dust or liquid scatters, the transparent plate acts as an eye protection plate. It is highly safe because it prevents these from entering the eyes.
