The novel mask mounting belt (2) according to the present invention can be applied to any type of connected body (that is, the mask cover (a) or the belt holder (b)). First, the case where the connecting body (3) is a mask cover (a) that can be connected to a belt and can hold a filter mask will be described with reference to the accompanying drawings. In this case, by connecting the mask cover and the mask mounting belt of the present invention, the mask mounting device of the present invention is obtained. When the filter cover is held on the mask cover in the mask mounting device of the present invention, the composite of the present invention is obtained. It becomes a mask.

FIG. 2 is a perspective view of the mask mounting device 10 of the present invention as seen from the wearer side (air outflow side) before the forming mask 2 is mounted. FIG.
FIG. 3 is a perspective view of the molded mask 2 that can be attached to the mask mounting tool 10 as viewed from the mask mounting tool 10 side (air inflow side). As described above, the composite mask 1 of the present invention includes a filter mask, for example, a molding mask 2.
And a mask mounting device 10. The mask mounting device 10 of the present invention includes a mask cover 3 as a connector and a mask cover 3 connected to the mask cover 3, and furthermore, a mask cover 3 is provided at both ends of the mask cover 3. And a stretchable composite-type mounting belt portion 45 having at least an external band-shaped portion extending in a direction opposite to the third side.

As the filter mask that can be used in the composite mask of the present invention, a general filter medium for collecting dust can be used as it is, and a cloth plane mask (for example, a gauze mask), a handkerchief, A towel, or preferably a molded mask, can be used. The forming mask is made of, for example, a filter material having a fiber layer capable of collecting dust, preferably a nonwoven fabric filter material, and more preferably a nonwoven fabric filter material having a density gradient. In addition, it is desirable to provide a dense layer composed of ultrafine fibers (for example, a fiber diameter of 1 to 10 μm), and such a fiber layer can be obtained by, for example, a melt blown nonwoven fabric.
Furthermore, it is also possible to increase the collection efficiency by converting the filter medium into an electret. In the case of electretization, it is desirable to use a nonwoven fabric composed of polyolefin fibers, and a melt-blown nonwoven fabric composed of polypropylene fibers and a hydroentangled nonwoven fabric are preferred. If necessary, a deodorizing layer made of activated carbon, zeolite, activated carbon fiber, or the like, or a woven fabric, a net, or the like may be laminated on the filter medium for the purpose of reinforcement or decoration.

[0008] The molding mask is preferably composed of a multilayer structure, ie, a laminate, and each layer is preferably composed of a fibrous material. Examples of the layer made of a material other than the fiber material include a layer made of a net or a foam. The layer composed of the fiber material can be a non-woven fabric layer, a knitted fabric layer, or a woven fabric layer, and is preferably a non-woven fabric layer.
The forming mask can have a specific function and structure as a pre-filter layer, a main filter layer, a support and / or auxiliary filter layer, etc. for each fiber layer. The number of layers in the multilayer structure is not particularly limited, but is preferably 2 to 8
Layers, more preferably 3 to 5 layers.

[0009] The molded mask that can be used in the composite mask of the present invention typically includes an outer layer (that is, a fiber layer that becomes the mask front side at the time of mounting) / an intermediate layer / an inner layer (that is, a fabric layer that is placed on the back side of the mask at the time of mounting) 1 and 3, and the laminate is typically formed into a cup shape as shown in FIGS. In the molding mask formed of the laminate having the three-layer structure, the intermediate layer having a function as a main filter layer is generally preferably a nonwoven fabric, more preferably a nonwoven fabric made of fine fibers, for example, a melt-blown nonwoven fabric or an electretized nonwoven fabric. An easily split fiber nonwoven fabric (that is, a nonwoven fabric using a splittable conjugate fiber or a nonwoven fabric using a split fiber obtained by reducing a film) or the like can be used. In particular, the average fiber diameter is preferably 1 to 10 μm, more preferably 1 to 5
A melt blown nonwoven fabric of μm is preferred in that it has an excellent collecting ability. The fibers constituting these nonwoven fabrics are not particularly limited, but fibers made of a dielectric resin, for example, a polyolefin resin such as polypropylene or polymethylpentene, or a polycarbonate resin is preferable.

On the other hand, the outer layer and the inner layer function as a pre-filter layer and an auxiliary filter layer, respectively, and also have a function of maintaining the three-dimensional shape of the molding mask. Further, the outer layer has a function of improving the appearance of the molded mask, and the inner layer also has a function of improving the contact feeling of the wearer. It is preferable to use a nonwoven fabric for both the outer layer and the inner layer.
Any of these nonwoven fabrics is desirably a nonwoven fabric containing a heat-adhesive fiber, and in particular, a mechanically entangled nonwoven fabric having a small amount of fiber oil (preferably 0.15% by weight or less), such as a needle punch. A nonwoven fabric (excluding the fiber oil agent by washing with water) or a hydroentangled nonwoven fabric is preferred.
Such a mechanically entangled nonwoven fabric (water entangled nonwoven fabric, needle-punched nonwoven fabric, etc.) having a fiber oil content of 0.15% by weight or less, more preferably 0.13% by weight or less based on the weight of the nonwoven fabric, easily forms an electret, This is because the trapping ability is excellent despite the large gap between them and the low pressure loss. As the nonwoven fabric containing the heat-adhesive fiber, a nonwoven fabric composed of a dielectric fiber and a heat-adhesive fiber is suitable.

As the dielectric fibers, polyolefin fibers such as polypropylene fibers and polymethylpentene fibers are suitable. As the heat-adhesive fiber, a composite fiber composed of two or more resins having different melting points, such as polypropylene / polyethylene and polypropylene / modified polypropylene, particularly a polyolefin-based composite fiber which is itself dielectric is suitable. The heat-adhesive fiber and the dielectric fiber may be uniformly mixed, but rather, it is better to be composed of a layer of the dielectric fiber and a layer containing a large amount of the heat-adhesive fiber. This is preferable because the effect lasts long. When one of the outer layer and the inner layer (generally, the inner layer) is formed of a nonwoven fabric mainly containing heat-adhesive fibers or a nonwoven fabric consisting of only heat-adhesive fibers, the other (common) Specifically, the outer layer may be a knitted or nonwoven fabric mainly composed of dielectric fibers, for example, polyolefin fibers or yarns, or a knitted or nonwoven fabric composed solely of dielectric fibers.

The basis weight, apparent density, thickness and the like of each of the nonwoven fabrics constituting the intermediate layer, the outer layer and the inner layer can be appropriately adjusted so that the pressure loss of the molded mask after molding becomes an appropriate value. There is no particular limitation. Generally, the basis weight of the nonwoven fabric constituting the intermediate layer (before molding) is as follows:
Preferably it is 20 to 150 g / m ² , more preferably 40 g / m ² .
１２０120 g / m ² . If it is less than 20 g / m ² , the dust collecting efficiency of the obtained molded mask is reduced, and
If it exceeds m ² , the pressure loss of the obtained molded mask becomes large. The apparent density of the nonwoven fabric constituting the intermediate layer (before molding) is not particularly limited, but is preferably 0.05 to 0.15 g / cm ³ , and more preferably 0.1 to 0.15 g / cm ³ .
06 to 0.1 g / cm ³ . If the amount is less than 0.05 g / cm ³ , the obtained molded mask may not be able to collect dust sufficiently. If the amount exceeds 0.15 g / m ³ , the pressure loss of the obtained molded mask becomes large.

Although the basis weight of the nonwoven fabric constituting the outer layer (before molding) is not particularly limited, it is preferably from 40 to 40%.
300 g / m ² , more preferably 50 to 200 g / m ²
It is. The apparent density of the non-woven fabric constituting the outer layer (before molding) is not particularly limited, but is preferably 0.1%.
04 to 0.13 g / cm ³ , more preferably 0.06 to
0.1 g / cm ³ . The basis weight of the nonwoven fabric forming the inner layer (before molding) is not particularly limited, but is preferably 40 to 300 g / m ² , more preferably 50 to 200 g / m ² . The apparent density of the nonwoven fabric constituting the inner layer (before molding) is not particularly limited, but is preferably 0.04 to 0.13 g / cm ³ , more preferably 0.06 to 0.1 g / cm ³ . is there. In addition,
The total weight of the nonwoven fabric of the outer layer and the inner layer is 150 g / m ^2.
More preferably, it is more preferably 200 g / m ² or more. The total weight of the inner layer and the outer layer is 150 g
If it is less than / m ² , the resulting mask will have poor shape retention and may be deformed or collapsed during use, resulting in a large pressure loss. Further, the thickness of the molded mask of the composite mask according to the present invention is not different from the conventional one, but for example, in the case of a three-layer structure molded mask, the thickness measured at the top of the molded mask is preferably 0.8 to It is 3.5 mm, more preferably 1 to 2.5 mm.

The laminate used for molding the molding mask is not only the laminate having the three-layer structure of the outer layer, the intermediate layer, and the inner layer, but also the outer layer, the outer layer, and the intermediate layer of the three-layer laminate. In between, or between the intermediate layer and the inner layer, another fiber layer (for example, a decorative layer, a preliminary filter layer, a heat-resistant layer made of heat-resistant fiber, a non-combustible layer made of non-combustible fiber, A flame-retardant layer treated with a flame-retardant resin, a deodorizing layer containing activated carbon fibers, etc.) or a laminated layer having a four-layered structure provided with an activated carbon-containing layer, and a two-layered structure of an outer layer and an intermediate layer The laminate may be a laminate having a two-layer structure of an intermediate layer and an inner layer. In any of the above laminates, at least one layer (in the case of three or more layers, an intermediate layer other than the outer layer and the inner layer) is preferably a main filter layer such as a melt-blown nonwoven fabric made of fine fibers.

The activated carbon-containing layer has, for example, a structure in which activated carbon particles are sprayed on a fiber layer (especially a nonwoven fabric layer), and a fiber layer (especially a nonwoven fabric layer) is further laminated thereon.
A structure in which activated carbon particles are substantially uniformly dispersed and supported in a fiber layer (particularly, a nonwoven fabric layer), a structure in which an activated carbon layer is sandwiched between two fiber layers (particularly, a nonwoven fabric layer), or Alternatively, a structure in which activated carbon particles are dispersed and supported substantially uniformly in a fiber layer (in particular, a nonwoven fabric layer) may be sandwiched between two fiber layers (an activated carbon-free layer). It is preferable to provide such an activated carbon-containing layer on the molding mask of the present invention, since a deodorizing function can be imparted. The content of activated carbon in the activated carbon-containing layer is preferably from 10 to 400.
g / m ^2, more preferably from 20 to 150 g / m ^2. If the content is less than 10 g / m ² , the deodorizing effect becomes insufficient, and if it exceeds 400 g / m ² , the intake resistance increases. The number of activated carbon-containing layers in the molding mask of the present invention is not limited, but is preferably one. Also, the thickness of the activated carbon-containing layer is not particularly limited, but is preferably 0.5 to 10 mm, more preferably 1 to 7 mm.

When the activated carbon-containing layer has a structure in which activated carbon particles are sprinkled on a fiber layer and a fiber layer is further laminated thereon, the weight of the lower fiber layer is preferably 30 to 1
20 g / m ^2, more preferably from 40 to 100 g / m ^2, the basis weight of the upper fibrous layer is preferably 20 to 100
g / m ^2, more preferably from 30~90g / m ^2.
Further, it is desirable that the fiber layers forming these activated carbon-containing layers contain heat-adhesive fibers in order to ensure the loading of activated carbon particles.

As shown in FIG. 3, for example, the molded mask in the composite mask of the present invention is formed into a three-dimensional shape such as a bowl shape so as to maintain a constant three-dimensional shape and to easily fit the wearer's face shape. I do. That is, the inner surface of the molding mask does not directly contact the mouth and nose of the wearer,
It is preferable to have a three-dimensional shape that comes into contact with the wearer's face only at the periphery of the molding mask. As a forming step of the forming mask used in the composite mask according to the present invention, any forming method, for example, a thermoforming method can be used. For example,
According to the thermoforming method, the sheet-shaped laminate is heated or brought into contact with a pair of molds at room temperature or lower,
Alternatively, a thermoformed body three-dimensionally shaped into a bowl (cup) can be manufactured by contacting with a known pair of heating molds. The molding conditions are not particularly limited. Generally, in the former case, after heating at 120 to 160 ° C., molding with a mold is performed for 0.5 to 5 seconds, more preferably 0.5 to 5 seconds.
Perform for 2.5 seconds. Thus, a molded mask having shape retention and flexibility can be manufactured. A metal rod or a thin metal plate made of a metal such as aluminum or iron or a clasp (not shown) made of a material obtained by coating these with a resin such as a vinyl chloride resin is provided on an upper portion (a portion covering the nose) of the molding mask. In that case, it can be attached to the outside of the molding mask corresponding to the position of the nose after molding.

In the present specification, "holding" means that a suitable connecting tool is provided on both or one of the forming mask and the mounting tool for the forming mask, and the forming mask is used to attach the forming mask to the mounting tool for the forming mask. In addition to the case where the mounting mask is used, the case where the forming mask is simply carried inside the wearing device for the forming mask (on the wearer side or the air outflow side) without using the connecting tool is also included. The composite mask 1 shown in FIG. 1 has a filter mask, for example, a molded mask 2 attached and held inside a mask wearing device 10 of the present invention (on the wearer side or on the air outflow side), and then attached to the wearer. The following shows an embodiment of the present invention. As shown in FIG. 2, the mask mounting device 10 of the present invention includes a mask cover 3 acting as a mask holding unit, and a mounting belt unit 45. In the composite mask of the present invention, the mask cover can be a molded article having a fixed shape or a sheet-shaped non-molded article. The mask cover made of a non-molded body can be made of an elastic material or a fiber material.

Here, a molded body holding portion (for example, a mask cover) made of a molded body having a predetermined shape has shape retention like the above-mentioned molded mask. The shape retention of the molded body holding section (for example, a mask cover) can be appropriately determined according to the type of mask to be used. The molded body holding portion (for example, a mask cover) can be molded from, for example, a sheet material or a resin material using a molding die. Alternatively, a molded body holding unit (for example, a mask cover)
Prepare a sheet material cut out according to the outer shape of the
An appropriate cut (linear or planar) is made from the outer peripheral portion to the inside of the sheet material, the areas separated by the cut are appropriately overlapped, and fixed by appropriate fixing means (for example, rivets or sewing). Thus, by forming a three-dimensional shape, it is possible to obtain a target molded body holding portion (for example, a mask cover).

The mask cover can hold a filter mask (for example, a forming mask). Note that it is only necessary to insert a filter mask (for example, a forming mask) inside the mask cover. The holding means is not particularly limited. For example, as shown in FIGS. 2 and 3, a connecting tool 21 is provided on the outer surface (gas inflow side) of the molding mask 2, and At a corresponding position on the inner (gas outflow side) surface, a corresponding connecting tool 31 is provided,
By connecting them, the forming mask 2 is connected to the mask cover 3.
Can be removably attached to the inner surface of the. Examples of the pair of connectors include a combination of a concave hook and a convex hook, a combination of a hook-and-loop fastener, and a combination of a button and a button hole. When the gas inflow side surface of the filter mask (for example, a forming mask) is made of nonwoven fabric, the filter mask (for example, the forming mask) may be held by a male surface fastener provided inside the mask cover. it can.

Further, when a molded mask is used, since the molded mask has shape retention and flexibility, a molded body is also used as a mask cover, and the molded mask is provided inside the molded body mask cover. By providing a recess that fits the outer (air inflow side) surface contour and into which the molding mask can be fitted, and by fitting the molding mask into the recess, the molding mask is removably attached to the inner surface of the mask cover. You can also. Also, a plurality of tongue pieces may be provided inside the mask cover (particularly, at the peripheral edge), and the outer periphery of the mask may be removably attached by being sandwiched between the tongue pieces and the inner surface of the mask cover. it can.
Therefore, in the composite mask of the present invention, when the filter characteristics of the filter mask (for example, the formed mask) are deteriorated, the filter mask (for example, the formed mask) is used.
By replacing only the filter, the filter characteristics can be maintained in a good state.

In the composite mask and the mask mounting device of the present invention, it is preferable that the mask cover holding the filter mask (for example, a forming mask) has a structure that substantially guarantees the gas permeability of the held filter mask. Here, the “structure that substantially guarantees the air permeability” means that the air permeability originally possessed by the filter mask when used alone is used even when the filter mask is used while being held on the mask cover. Means a structure in which the filter mask is substantially undisturbed and the filter mask can substantially fulfill the function as a filter.

The mask cover is made of a material having no air permeability (eg, a sheet material or molded product made of plastic, elastomer, rubber, or leather (synthetic leather, natural leather, or artificial leather)). If you have
For example, as shown in FIGS. 1 and 2, one or more ventilation holes 32 can be provided in the mask cover 3. Also, a mesh window can be provided at the center of the mask cover, and the entire mask cover can be formed from a mesh structure. The size of the mask cover is not limited as long as it is a structure that substantially guarantees the above-described air permeability. The size of the mask cover is larger than the mask, completely covers the entire mask, or smaller than the mask. It can be large enough to protrude.

Ventilation holes as described above (including mesh windows)
When the outer surface (gas inlet side surface) of the filter mask (for example, a forming mask) held inside the mask cover directly contacts the inner surface (gas outlet side surface) of the mask cover, At the contact surface, the filter characteristics of the filter mask (especially the molding mask) cannot be used. Therefore, for example, when the molding mask is held in the filter mask, a space is formed between the inner surface of the mask cover and the outer surface of the molding mask, and the space between the outer surface of the molding mask and the inner surface of the mask cover is formed. It is preferable to use a mask cover or a molding mask made of a molded body having a structure capable of minimizing the contact area. For example, as shown in FIG. 4, although the outer surface contour of the molding mask 2 and the inner surface contour of the mask cover 3 substantially correspond to each other, the molding mask 2 and the mask cover 3 are brought into contact only at the peripheral portion. ,
If the structure does not make contact at the center, a space 7a is formed between them. Also, since the molding mask 2 is a molded body that does not come into contact with the mouth or nose of the wearer 8, when the molding mask 2 is worn on the wearer 8 by the wearing belt 45, the molding mask 2 is also in contact with the wearer 8. A space 7b is formed therebetween.

Further, a spacer can be inserted between the mask cover and the forming mask to form a space between the inner surface of the mask cover and the outer surface of the forming mask. In this case, for example, as shown in FIG. 5, it is not necessary to change the outer surface contour shape of the molding mask 2 and the inner surface contour shape of the mask cover 3. The spacer provided between the mask cover and the forming mask is preferably provided in such a manner as not to interfere with the filter characteristics of the forming mask. For example, as shown in FIG. 3, it is preferable to provide a thin rod-shaped spacer 9a continuously or intermittently on the outer surface of the peripheral portion of the molding mask 2. Further, a thin rod-shaped or dot-shaped spacer can be provided at the center of the forming mask so as not to hinder the filter characteristics of the forming mask, or it can be provided on both the forming mask and the mask cover. Instead of providing the spacer on the outer surface of the peripheral and / or central part of the molding mask, it can be provided at a corresponding position on the inner surface of the mask cover. Further, as shown in FIG. 5, a spacer 9b can be provided on the inner surface of the peripheral portion of the forming mask to further enlarge the space between the inside of the forming mask and the wearer. When a space is formed between the inner surface of the mask cover and the outer surface of the molding mask, at least one vent hole capable of supplying a sufficient amount of gas (air) into the space, It is sufficient to provide it on the mask cover.

The spacer to be inserted between the mask cover and the molding mask may be made of a material having no air permeability (for example, resin, especially hot melt resin) or a material having air permeability, for example, a net-like material, fiber It can be formed from a material (eg, a woven or knitted or non-woven fabric) or a foam. When a material having air permeability is used, a material having a smaller pressure loss than a molding mask is preferable. A spacer made of a material (for example, a foam) having a smaller pressure loss than the molding mask can be inserted in a state where the spacer is filled in a space between the mask cover and the molding mask.

[0027] The mask cover may be formed of a material having air permeability. As a material having air permeability,
A cloth (for example, a woven or knitted fabric or a non-woven fabric) or a net-like material of the same or different material as the material of the filter mask (particularly, the forming mask) can be used, and the inter-fiber space of the filter mask (particularly, the forming mask) It is preferable to use one having a larger pressure drop than that of the above).

In the composite mask and mask mounting device according to the present invention, when a molded body is used as a mask cover and a molded mask is used as a filter mask, the wind pressure received when the wearer is riding on a motorcycle and running. It is preferable to have such a rigidity that the shape of the mask cover molded body can be substantially maintained. Further, when the wearer falls down while traveling on the motorcycle, it is preferable that the mask cover molded body is damaged, and the broken piece has such flexibility as not to damage the wearer's face and the like. . When the above-mentioned spacer (particularly, a foam spacer of a type that fills a space between the molded body mask cover and the molded mask) is used, the shape of the mask can be maintained while maintaining the shape retention performance against wind pressure applied to the mask cover molded body. It is preferable because the rigidity of the cover molded body is easily reduced and the flexibility is easily increased.

In the composite mask and mask mounting device of the present invention, the mounting device includes a mounting belt portion connected to the mask cover. For example, as shown in FIG. 1 and FIG. 2, the wearing belt portion 45 moves in a transverse direction (the direction of arrow A in FIG. 1) from one cheek to the other cheek of the wearer when the composite mask 1 is worn. It may be a single mounting belt 45 extending through the central portion of the molding mask 2 on the gas inflow side. In this case, the mounting belt 45 includes an inner band-shaped portion 41 overlapping with the mask cover 3 and two outer band-shaped portions 42a and 42b extending from both ends of the mask cover 3 in directions opposite to the mask cover 3, respectively. . The mounting belt connects and / or connects the inner band portion and the mask cover by a belt pass-through provided in the mask cover (for example, formed from a pair of slit-shaped holes provided in the mask cover) and / or a fixture. Can be fixed. When the belt passer and / or the fixing device are provided, their positions and numbers are not limited. For example, as shown in FIG. 1, a belt passer 35 is provided at the center of the mask cover 3,
Fixtures 34 may be provided at both end regions of the mask cover 3 to connect and / or fix the mounting belt 45 to the mask cover 3. As shown in FIGS. 1 and 2, when the wearing belt 45 is formed of one belt and is worn on the wearer's head by the wearing belt 45,
It is necessary that the entire length is longer than a length that can make one round of the outer periphery of the wearer's head in the mounting direction. In addition, the head cover that the wearer wears separately (for example,
(A helmet), it is necessary to have a length that can be connected to the connecting tool provided on the head cover or a length that is longer than a length that can make one round around the outer periphery of the head cover.

Further, the above-mentioned wearing belt portion is, for example,
As shown in FIG. 6, each is fixed to the mask cover 3, preferably at both end regions thereof by fixing members 34,
Two mounting belts 42a, 42b extending from both ends thereof in directions opposite to the mask cover 3 respectively.
Can also be In this embodiment, when the belt is worn on the wearer's head by the wearing belts 42a and 42b, the length of the wearing belt is equal to the sum of the lengths of the two wearing belts, and both fixed to the mask cover. It is necessary that the sum of the distance between the components is longer than a length that can make one round of the outer circumference of the wearer's head in the mounting direction. Further, when connecting to a head cover (for example, a helmet) separately worn by the wearer, a length longer than a length connectable to a connecting tool provided on the head cover or a length capable of making one round of the outer periphery of the head cover. It is necessary to have

Further, the mounting belt portion may be fixed at one end region of the mask cover, and may include a single band-like portion extending from the fixed end region to the outside of the mask cover. In this case, the length of the one mounting belt portion is determined by the sum of the length of the mounting belt portion and the distance from the fixed end region to the opposite fixed end region in the mask cover.

Works. FIG.
2 shows a state in which the composite mask 1 is mounted. As shown in FIG. 9, since the ear of the wearer is not covered when the wearer wears the ear, it is preferable in that the ear does not hurt or the surrounding sound is reduced, so that it is difficult to perceive danger. . In addition, there is an effect that even if a helmet is mounted after the composite mask is mounted, a positional shift hardly occurs.

As shown in FIGS. 8 and 9, the ear detour may be shaped to pass under the ear when worn.
As shown in FIG. 10, it may be shaped to pass over the ear when worn. Furthermore, it may be shaped to pass above and below the ear when worn. In the case of a shape that passes under the ear, the positional displacement when the helmet is attached is further less likely to occur. Also,
The ear detour may be a bent portion as shown in FIGS. 8 to 10 or may be an arcuate curved portion. Further, as shown in FIGS. 8 to 10, the bent portion does not need to be formed of one bending point, and may be formed of two or more bending points. Further, the ear detour may be composed of a combination of a bent portion and a bent portion. Also in these non-linear type wearing belts 40, the high elasticity portions 46 are provided on both end portions outside the ear detours 44, and the low elasticity portions 47 are provided at the center inside the ear detours 44.
