Description

The present invention relates to a mask that covers the wearer's nostrils and mouth.

Today, it is widely recognized that wearing a mask is very important for people who have symptoms of the common cold syndrome, for people who suffer from hay fever when pollen arrives, and as a measure against the spread of viral infections. There is.

Here, for example, in a situation where it is strongly recommended to wear a mask when going out in response to a virus infection that is spreading nationwide, the mask will be worn for a considerable period of time. Improving the comfort of wearing is a major issue.

As a measure for improving the wearing feeling, for example, in Patent Document 1, the mask body has a skin facing surface and a non-skin facing surface and has a pleated structure, and the mask body has a skin facing surface. The cellulose cloth includes a cellulose cloth which forms a part of a surface and has moisture absorption and a synthetic fiber cloth which constitutes a non-skin facing surface, and the cellulose cloth has a larger number of fiber ends per unit area than the synthetic fiber cloth. Further, the mask body is a nose cover portion made of synthetic fiber cloth that covers the wearer's nose, and is at least 30% in the vertical direction of the mask body from the upper end edge extending along the lateral direction in the mask body. A mask is disclosed that has a nasal cover that extends to the length of. Here, according to such a mask, it is said that while enhancing the hygroscopicity of the mask during use, it is easy to suppress the discomfort on the wearer's face, and an excellent wearing feeling can be obtained.

Further, in Patent Document 2, a mask main body portion that covers a target portion of the wearer's face, a pair of left and right ear hook portions for locking the mask main body portion to the wearer's ear, and a wearer's nasal cavity are expanded. A mask including a nasal cavity dilation portion, which is a plate-shaped elastic member and both side portions of the elastic member sandwiching the nasal bridge of the wearer's nose via a sheet material forming the mask main body portion. A mask characterized by having a sticking portion to be stuck to is disclosed. Here, according to the mask having such a nasal cavity dilated portion, it is said that nasal breathing can be performed well and the wearing feeling is also good.

However, in the conventional masks as described in Patent Documents 1 and 2, there is a problem that a painful sensation such as suffocation or heat is still generated while wearing the mask.

That is, even if the pleated structure of Patent Document 1 or the nasal dilation / pleats of Patent Document 2 is adopted, it is sucked from the beginning when the mask is used for a long time or repeatedly, or depending on the structure of the mask. Each time the movement is performed, the cloth portion of the mask body approaches or sticks to the nasal cavity or mouth, and it tends to cause a suffocation during nasal breathing or mouth breathing.

Further, when the cloth portion of the mask body approaches or sticks to the nostrils or the mouth in this way, the wearer tends to feel the heat. In particular, it is quite possible to wear a mask for a long time even in the summer when going out to prevent the spread of viral infections, but in that case, the heat of the wearer causes heat stroke. There is a possibility and it becomes a big problem.

It is a schematic diagram which shows the further other embodiment of the mask by this invention. It is a schematic diagram for demonstrating the effect of the mask by this invention. It is a schematic diagram which shows the further other embodiment of the mask by this invention.

Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the accompanying drawings. In each drawing, the same element is shown using the same reference number. Further, the dimensional ratios within the components and between the components in the drawing are arbitrary for the sake of readability of the drawing.

FIG. 1 is a schematic view showing an embodiment of a mask according to the present invention. Further, FIG. 2 is a schematic view showing various shapes that can be taken in the shape-retaining material according to the present invention.

The mask 1 of the present embodiment shown in FIG. 1 is worn to prevent, for example, a person who has a symptom of cold syndrome from scattering droplets containing a virus or a bacterium to the outside as much as possible, or pollen when pollen arrives. It is possible to prevent people suffering from illness from taking pollen into the body as much as possible. In addition, as a measure against the spread of viral infections, it also contributes to suppressing the spread of virus infections, especially when worn when going out.

Specifically, the mask 1 is
(A) A covering portion covering at least the nostrils and mouth of the wearer (right covering portion 111 and left covering portion 112 in FIG. 1) and
(B) A mounting part for fixing the covering part (right covering part 111 and left covering part 112) to the wearer's head (right wearing part 121 and left wearing part 122 in FIG. 1), and
(C) A shape-retaining material (131, 132, 133) attached along the "vertical center line" (FIG. 1) in the covering portion (right covering portion 111 and left covering portion 112), and the covering portion (131, 132, 133). It has higher rigidity than the forming material of the right covering portion 111 and the left covering portion 112), and may be at least one end side (hereinafter, a long side) extending along the extending direction of the shape-retaining material. ) (In FIG. 1, most of both long sides of the shape-retaining material) have a wavy shape that undulates in the plane including the shape-retaining material (131, 132, 133). And have
(D) The covering portion (right covering portion 111 and left covering portion 112) houses the shape-retaining material (131, 132, 133) provided on or near the center line (FIG. 1). It is characterized in that it is provided with a bag-shaped mounting portion (bag-shaped mounting portion 11A in FIG. 1). Hereafter, it is assumed that the "vertical center line" of the above (C) also includes a curved center line extending substantially vertically.

As described above, in the mask 1, the shape-retaining material (131, 132, 133) of the above (C) is attached along the center line (FIG. 1) by the attachment portion (bag-shaped attachment portion 11A). As a result, even if the wearer of the mask 1 inhales or exhales, the portion near the shape-retaining material (131, 132, 133) in the covering portion (right covering portion 111 and left covering portion 112) and the wearer The distant positional relationship between the nostrils and the mouth is maintained with almost no change. As a result, it is possible to avoid a situation in which a part of the covering portion (111, 112) approaches or sticks to the nostrils or the mouth each time the sucking motion is performed. That is, according to the mask 1, it is possible to reduce the painful sensations such as suffocation and heat when worn.

In particular, in situations where there is concern about the spread of viral infections, it is quite possible to wear a mask for a long time even in the summer when going out, but even in such a case, wear the mask 1. This makes it possible to contribute to the prevention of heat stroke, for example.

Further, the shape-retaining material (131, 132, 133) is higher than the forming material of the covering portion (111, 112) so that the shape can be maintained by the external force normally received by the mask 1 when worn. It is made of a rigid material. Specifically, the shape-retaining material (131, 132, 133) is made of polypropylene (PP) resin, polyethylene terephthalate (PET) resin, polyvinyl chloride (PVC) resin, or polyethylene (PE) resin, while It is also preferable that the covering portion (111, 112) is formed of a synthetic / natural fiber cloth or a non-woven fabric as described later. The shape-retaining material (131, 132, 133) may be cut out from the synthetic resin sheet as described above, or may be a molded product of the synthetic resin.

Here, PP resin and PET resin, which can be used as a forming material for shape-retaining materials (131, 132, 133), have the required rigidity and have safety so as to be used as a material for food containers. Therefore, it is more suitable as a constituent material of the mask 1 which is located near the face. By the way, in general, PET resin has higher rigidity (for example, elastic modulus such as Young's modulus and rigidity) than PP resin, and therefore, the shape-retaining material made of PET resin has a bag-shaped attachment portion. It has been confirmed that it is easier to insert (store) into 11A (and the bag-shaped attachment portions 21A, 21A', 31A and 51A described later).

However, of course, the shape-retaining material (131, 132, 133) may be formed of another forming material, for example, a metal such as lead, lead alloy, aluminum, or stainless steel, or, for example, a metal body as a core ( It may be a synthetic resin body such as a coated silicon resin. In any case, various materials can be adopted as the forming material as long as the shape of the shape-retaining material can be maintained by the external force normally received by the mask 1 when worn.

Further, both the shape-retaining material 131 and the shape-retaining material 132 in the present embodiment are bent with a ridge line extending in the vertical direction (extending direction of the shape-retaining material) as shown in FIG. As a result, even if an external force is applied in the lateral direction (direction orthogonal to the extension direction of the shape-retaining material), the shape can be held more stably, and a part of the covering portion (111,112) is covered. It is possible to more reliably avoid the situation where the nostrils and mouth are approached or stuck close to each other. Here, the cross section of the shape-retaining material 131 and the shape-retaining material 132 in the lateral direction (width direction) is V-shaped, but of course, the cross section is not limited to this, and may be W-shaped or U-shaped, for example. Good.

Further, as the shape-retaining material to be attached (inserted) to the bag-shaped attachment portion 11A, it is also possible to adopt a flat plate-shaped shape-retaining material 133 having no bending. Since the shape-retaining material 133 does not have any bends, it is easier to insert (store) it into the bag-shaped attachment portion 11A or take it out from the bag-shaped attachment portion 11A. Here, it is also possible to make the shape-retaining material 133 into a curved plate shape.

Further, unlike the shape-retaining material 132, the shape-retaining material 131 in the present embodiment has a curved shape (so-called banana shape) as it advances in the vertical direction (extension direction). Therefore, by attaching (inserting and storing) such a shape-retaining material 131 to the bag-shaped attachment portion 11A which is a linearly extended tubular shape (as will be described later), the shape of the mask 1 can be changed. It is also possible to maintain the shape so that the inside is recessed. By the way, in this case, the center line (FIG. 1) is also bent according to the shape of the shape-retaining material 131.

The shape-retaining material 131 shown in FIG. 1 is curved so as to include the back side of the ridge line inward (so that the ridge line becomes convex), but conversely, the ridge line is included in the inside (ridge line). May be curved (so that is concave). In any case, it is preferable that the shape-retaining material 131 is attached in a direction in which the inside of the mask 1 is recessed due to its curved shape.

On the other hand, although the shape-retaining material 132 has a linearly elongated shape, it can also be attached to the linearly elongated tubular attachment portion 11A. Here, even in such an embodiment, if the forming material of the covering portion (111,112) is a cloth material having elasticity as described later, the mask 1 is worn by the wearer to form the shape. The retaining material 132 can be deformed along a curved line including the wearer's nose and chin to maintain its shape. That is, even in such an embodiment, it is possible to avoid a situation in which a part of the covering portion (111, 112) approaches or sticks to the nostrils or the mouth up close. Incidentally, also in this case, the center line (FIG. 1) is bent according to the shape of the deformed shape-retaining member 132. The shape-retaining material 132 is preferably attached to the attachment portion (bag-shaped attachment portion 11A) so that the ridgeline side (pointed side) faces the outside of the mask 1, but conversely, it is inside the mask 1. It is also possible to attach it so that it faces.

Further, as shown in (C) above, at least a part of at least one long side of the shape-retaining material (131, 132, 133) (most of both long sides in FIG. 1) is the "shape-retaining material". It has a "wave shape" that undulates in the "plane containing". Here, this "surface including the shape-retaining material" is a curved surface that is bent at the ridge line in the shape-retaining material 131, is a flat surface that is bent at the ridge line in the shape-retaining material 132, and is bent in the shape-retaining material 133. It is a flat surface without a ridge. Hereinafter, various aspects of this "wave shape" will be described with reference to FIGS. 2 (A) to 2 (C).

First, FIG. 2A shows various shapes A to G as shapes that can be adopted on the long side of the shape-retaining material 133. Here, all of the shapes A to G have a wavy shape that undulates in the plane including the shape-retaining material 133 (in the paper surface in FIG. 2). Further, in the shape-retaining material 133 adopting these shapes A to G, the width thereof (in the left-right direction orthogonal to the extension direction) increases and decreases as at least a part of the long side advances along the extension direction. And fluctuate repeatedly.

Further, in FIG. 2A, the shape-retaining material 133 has a shape such that the circumscribed shape is substantially rectangular, but as a modification mode, the width takes a maximum value around the center in the extension direction, and the circumscribed shape thereof. May have a shape that is substantially spindle-shaped. Alternatively, the width may have a maximum value around the upper end or the lower end in the extension direction, and the circumscribed shape may be a trapezoid that is substantially extended.

Further, as a further modification mode, as shown in G'shown in FIG. 2 (B) and E'shown in FIG. 2 (C), the phase of the wave shape on the right long side and the left in each of the shapes A to G It is also possible to adopt shapes A'to G'that are out of phase with the wave shape on the long side in the extension direction (in FIGS. 2B and 2C, they are out of phase by half a wavelength). .. Of course, the left and right long sides may have different types of wave shapes. For example, it is also possible to use a shape-retaining material 133 having a long left side having a shape A and a long right side having a shape B.

The wave shape of the long side of the shape-retaining material 133 is not limited to the shapes A to G and the shapes A'to G'as described above, and is, for example, a pulse shape having an edge as an angle. , A variety of shapes that imitate some kind of waveform, such as a pulse shape with rounded edges, a continuous semicircle shape, and a wave shape in which multiple waves with different frequencies are superimposed on each other, can be adopted. .. Further, only one long side of the shape-retaining material 133 may have a wavy shape as described above. However, it is more preferable that both long sides have a wavy shape in order to obtain the effect described later.

In any case, the shape-retaining material 133 having the long side of the wave shape as described above is housed in the attachment portion (bag-shaped attachment portion 11A in FIG. 1) which is a bag-shaped portion to be described in detail later. Even if an external force that the mask 1 normally receives when worn is applied, it becomes difficult to move, especially in the vertical direction. As a result, the bag-shaped portion (bag-shaped attachment portion 11A) can be stably fitted without shifting.

If the shape-retaining material 133 is designed so that the maximum width of the shape-retaining material 133 firmly hits the inner surface of the bag-shaped portion (bag-shaped mounting portion 11A), the shape-retaining material 133 has a wave on its long side. This is because it is difficult to move (shift) in the vertical direction even if a considerable static frictional force is received from the inner surface of the bag-shaped portion around the maximum point of the mask 1 and an external force normally received by the mask 1 when worn is applied. .. In this respect, for example, as compared to a generally rectangular shape-retaining material having straight long sides, it is understood that the shape-retaining material 133 receives a greater static friction force at more points (per maximal point). is there.

In this way, the shape-retaining material 133 having the long side of the wave shape is stably fixed to the mask 1 (bag-shaped attachment portion 11A) without being particularly displaced in the vertical direction. As a result, the effect of reducing the painful sensation during wearing can be stably achieved, and it is also possible to provide a better wearing feeling because it is not necessary to give the wearer a sense of discomfort due to misalignment. Furthermore, even when the upper end of the bag-shaped portion (bag-shaped mounting portion 11A) is opened so that the shape-retaining material 133 can be taken in and out (detachable), the stored shape-retaining material 133 is intended. It is possible to avoid the situation where the bag pops out as much as possible. By the way, the inventor of the present application has confirmed through a plurality of experiments that the effects described above are exhibited.

Further, when the bag-shaped portion (bag-shaped mounting portion 11A) allows the shape-retaining material 133 to be taken in and out (detachable) as described above, the shape-retaining material 133 having a wavy long side is not so large. It can be inserted (stored) in and taken out from the bag-shaped portion (bag-shaped attachment portion 11A) without imposing a burden. Here, in particular, the shape-retaining material 113 preferably has a long side of a wave shape having a curved line having no corners, such as the long sides of the shapes A to G and the shapes A'to G'described above. .. Further, it is also preferable that the head portion (lower end side portion) at the time of insertion (storage) and the head portion (upper end side portion) at the time of removal are also rounded without corners. Since the shape-retaining material 133 having such a shape does not have a corner portion that is easily caught on the inner surface of the bag-shaped portion, it can be inserted (stored) or taken out into the bag-shaped portion (bag-shaped mounting portion 11A). , It will be easier. By the way, the inventor of the present application has also confirmed through a plurality of experiments that the effects described above are exhibited.

As described above, various aspects of the wave shape of the long side of the shape-retaining material 133 have been described with reference to FIG. 2, but these wave shapes are naturally adopted for the long side of the shape-retaining material 131 and the shape-retaining material 132. Can be done. For example, shapes A to G and shapes A'to G'may be adopted on the long sides of the shape-retaining material 131 and the shape-retaining material 132. Further, the shape-retaining material 131 and the shape-retaining material 132 having such a long side of the wave shape also exert the effects as described above, similarly to the shape-retaining material 113.

Next, returning to FIG. 1, the attachment portion which is the bag-shaped portion of the above (D) is a part of the covering portion, but is the bag-shaped attachment portion 11A in the present embodiment. The bag-shaped attachment portion 11A is a center line formed by suturing, adhering, or thermocompression bonding the first cloth part and the second cloth part (FIG. 1), which are two cloth parts (constituting the covering part). It is a bag-shaped portion that extends along (FIG. 1). Specifically, as shown in FIG. 1, the bag-shaped mounting portion 11A of the present embodiment has two rows of seams after overlapping the ends of the first cloth part and the ends of the second cloth part. Is formed by sandwiching the center line (FIG. 1) and suturing the two rows of seams so as to form a linearly extended tubular bag.

Further, it is also preferable that the bag-shaped attachment portion 11A is closed by suturing, adhering, thermocompression bonding, or the like so that the shape-retaining material (131, 132, 133) does not come out from the lower end. Here, the lower end of the bag may be closed after storing the shape-retaining material (131, 132, 133), but in the present embodiment, the bag-shaped mounting portion 11A is the shape-retaining material (131, 132, 133,). 133) is attached (stored) in a form that can be taken in and out. Specifically, the upper end of the bag is left open as it is, or the shape-retaining material (131, 132, 133) pops out unintentionally. It is also preferable to make a crease or a catch on the upper end of the bag so that the shape-retaining material (131, 132, 133) can be picked up with fingers so that the bag can be taken out.

In any case, by taking out the shape-retaining material (131, 132, 133) when not wearing the mask, it is easy to fold the mask 1 into small pieces, wash the mask 1 by hand, or wash it with a dedicated device. It becomes.

Here, as already described with reference to FIG. 2, if the shape-retaining material (131, 132, 133) is designed so that the maximum portion of its own width firmly hits the inner surface of the bag-shaped portion, Since it has a wavy end edge, it is stably fixed in the bag-shaped portion (bag-shaped mounting portion 11A) without shifting in the vertical direction. As a result, the effect of reducing the painful sensation during wearing can be stably achieved, and it is also possible to provide a better wearing feeling because it is not necessary to give the wearer a sense of discomfort due to misalignment. Further, even when the upper end of the bag-shaped portion (bag-shaped mounting portion 11A) is opened so that the shape-retaining material 133 can be taken in and out (detachable), the stored shape-retaining material 133 is unintentionally used. It is possible to avoid the situation of popping out as much as possible. On the other hand, the shape-retaining material 133 having a wavy long side can be inserted (stored) into a bag-shaped portion (bag-shaped mounting portion 11A) or a bag-shaped portion (bag) without imposing a large load. It can also be taken out from the shape mounting portion 11A).

The maximum value of the lateral width (when stretched flat) of the shape-retaining material (131, 132, 133) can be, for example, 3 to 15 mm (mm). Further, the thickness may be, for example, 0.2 to 1 mm. On the other hand, the size of the bag in the bag-shaped attachment portion 11A can also be set so that the shape-retaining material (131, 132, 133) having such a width and thickness is just stored. Incidentally, one embodiment relating to a width larger than these will be described later with reference to FIG. 7.

Further, the bag-shaped attachment portion 11A (covering portion) is formed of various cloth materials as described later in the present embodiment, and the cloth material stretches as it is repeatedly used while being washed or the like. , Its size, for example, the inner diameter width of the bag increases. Therefore, shape-retaining materials (131, 132, 133) having a maximum width larger than the initial inner diameter width of the bag (before spreading) are prepared in advance, and appropriately according to the spreading of the bag-shaped mounting portion 11A. It is also preferable to use shape-retaining materials (131, 132, 133) that can be stored without play. For example, when the initial (before spreading) inner diameter width of the bag in the bag-shaped mounting portion 11A is 10.5 mm, the three shape-retaining materials (131, 132) have maximum widths of 10 mm, 10.5 mm, and 11 mm, respectively. , 133) may be prepared, and the one with the maximum width of 10 mm may be used at the beginning.

Next, also in FIG. 1, the covering portion of the above (A) has a central attachment portion (bag-shaped attachment portion 11A) as a part thereof, but in the present embodiment, the center line (FIG. 1) is used as a boundary. It is divided into a right covering part 111 and a left covering part 112. The covering portion (111,112) can be formed from a non-woven fabric used for a normal mask, a charged non-woven fabric, a cotton fabric (gauze), a filter-sewn type gauze, or the like. It is also preferable to form a laminated body in which a plurality of these are laminated.

However, in the present embodiment, the covering portions (111, 112) are formed of a cool contact cloth that has elasticity and exhibits a maximum heat absorption rate of a predetermined value or higher. Here, the "maximum heat absorption rate of a predetermined value or higher" depends on the performance setting of the mask as a commercial product, but it is also preferable that the q-max value is 0.2 or more, for example. Further, such a cool contact cloth can be, for example, a synthetic fiber cloth such as nylon, polyester, linen, or rayon, or a natural fiber cloth such as processed cotton or silk, and is further cooled. It is also preferable to have a high-density knitting structure in order to improve the feeling. It is also preferable that the knitting structure exhibits elasticity in two orthogonal directions, that is, a 2-way stretch knitting structure. In any case, such a cool contact cloth improves the wearing feeling of the mask 1 and also contributes to reducing the heat and coldness at the time of wearing.

Further, as a modification, the covering portion (111, 112) is a portion covering at least two skin position ranges on the right ear side and the left ear side when viewed from the wearer's nostrils and mouth (cover shown in FIG. 6).

(B) It may be composed of a single layer of a cool contact cloth having a back surface showing a maximum heat absorption rate lower than that of the front surface. Here, in general, the cool contact cloth is often a cloth material having the front surface (a) and the back surface (b).

In this case, the mask 1 may have the front surface of the above (a) as the wearer's face side (inside), or the back surface of the above (b) as the wearer's face side (inside). It can be a reversible type mask that can also be used. This also allows the wearer to select a more suitable wearing mode with less distress, for example, according to the season and environment.

As a further modification, the covering portion (111, 112) covers at least two skin position ranges on the right ear side and the left ear side when viewed from the wearer's nostrils and mouth (FIG. 6). The covering part is separated / contacted part), and in this embodiment, the entire covering part is
(A) The bottom layer is a cool contact cloth that exhibits a maximum heat absorption rate of a predetermined value or higher.
(B) It may have a laminated structure of at least two layers with a cloth showing a maximum heat absorption rate lower than that of the cool contact cloth as the uppermost layer.

In this case as well, the mask 1 may have the lowermost layer of the cool contact cloth of the above (a) on the face side (inside) of the wearer, or the uppermost layer of the cloth of the above (b) of the wearer. It is possible to use a reversible type mask that can be on the face side (inside). Thereby, the wearer can also select a more suitable wearing mode with less feeling of pain, for example, according to the season and the environment.

Finally, also in FIG. 1, the right mounting part 121 and the left mounting part 122, which are the mounting parts of the above (B), are made of the same parts as the right covering part 111 and the left covering part 112, respectively, in the present embodiment. It is a part (specifically, it is composed of a first cloth part and a second cloth part, respectively), and has openings 121a and 122a, respectively. The wearer can wear the mask 1 by hanging the circumferences of the openings 121a and 122a around his right and left pinna, respectively.

Here, when the right-mounted portion 121 and the left-mounted portion 122 are formed of elastic cloth (similar to the right-covered portion 111 and the left-covered portion 112), this wearing operation becomes easier. In addition, it is possible to obtain a more stable wearing feeling. Of course, the right-handed part 121 and the left-handed part 122 may be parts that take other wearing modes, and may be, for example, a string for ear hooking.

Although the mask 1 as an embodiment of the mask according to the present invention has been described in detail above, various various components of the mask, such as a covering portion including a mounting portion, a mounting portion, and a shape-retaining material, are used. The change mode is possible.

As the present mask, it is also possible to adopt the mask 5 (having the same or similar structure as the mask 1), which will be described later with reference to FIG. 7.

In the present embodiment, the covering portion and the mounting portion of the mask (1, 2, 2', 3) have elasticity and are equal to or higher than a predetermined value (in the present embodiment, the q-max value is 0.2 or higher). ) It is composed of a cool contact cloth (in the case of a laminated structure, a cloth laminated on the outside) showing the maximum heat absorption rate. In addition, shape-retaining materials (131, 132, 133, 231,232, 233, 331, 332, 333) are inserted and stored in the bag-shaped mounting portions (11A, 21A, 21A', 31A) to cover them. The portion near the shape-retaining material at the site and the nostril and mouth of the wearer are separated from each other at a substantially constant interval. Further, the portion of the covering portion other than the vicinity of the shape-retaining material is composed of only a single-sided cloth (in the case of a laminated structure, a cool contact cloth and a cloth laminated on the outside) including the cool contact cloth. There is. That is, it does not have a structure such as pleats.

Here, when the wearer breathes (nasal breathing and / or mouth breathing) in a situation where the mask (1, 2, 2', 3) is worn by the wearer as shown in FIG.
(A) The positional relationship between the "near part of the shape-retaining material" in the covering part and the wearer's nostril and mouth is maintained (the nearby part and the nostril and mouth are separated from each other at a substantially constant interval. As it is),
(B) Two parts of the covering part covering the two skin position ranges on the right ear side and the left ear side when viewed from the wearer's nostrils and mouth (“covering part separation / contact part” in FIG. 6). However, it separates or comes into contact with the skin position range according to the wearer's breathing.

That is, in a state where the "near portion of the shape-retaining material" in (a) above and the wearing portion placed on the wearer's auricles hardly change their positions on the face, they are sandwiched between them. The "covering area separation / contact area" is separated or contacted with respect to the skin position range according to the wearer's breathing (because it is composed of only a single-sided cloth). As a result, each time the wearer inhales,
(A) Without a part of the covering part coming close to or sticking to the nostrils or mouth
(B) The contact cooling sensation cloth will come into contact with the skin position range again (repeatedly).
As a result, it is possible to further reduce the heat and coldness at the time of wearing.

It should be noted that the specific position range and the area of the above-mentioned "covering portion separation / contact portion" may change depending on the design content of the mask, the shape of the wearer's face, and the breathing mode of the wearer. However, the present mask of the present embodiment is characterized in that at least such a "covering site separation / contact portion" is expressed to the extent that it can be visually recognized.

In this way, by using the wider shape-retaining material (531,532), it is possible to more reliably avoid the situation where a part of the covering portion (511,512) approaches or sticks to the nostrils or the mouth. It becomes possible to do.

Further, in the present embodiment, the shape-retaining material 531 is wide, and in order to further reduce the suffocation and heat when the mask 5 is worn, at least one (six in FIG. 7) through-holes 531a have. Further, the shape-retaining material 532, which is also wide, functions as a filter in order to more reliably prevent the situation where droplets containing pollen, virus, etc. pass through the mask 5 worn. It has a mesh-like portion 532a.

Of course, as for the bag-shaped mounting portion 51A, as in the bag-shaped mounting portion 11A (FIG. 1), the lower end of the bag is closed by suturing, bonding, thermocompression bonding, etc., while the upper end of the bag is left open as it is. Alternatively, it is also preferable to make a crease or a catch on the upper end of the shape-retaining material so that the shape-retaining material does not easily pop out, and then pinch the shape-retaining material with a finger so that the shape-retaining material can be taken out from the bag. In this case, by taking out the shape-retaining material when not wearing the mask 5, for example, it becomes easy to fold the mask 5 into small pieces, wash the mask 5 by hand, or wash the mask 5 with a dedicated device.

As described above, also in the mask 5 of the present embodiment, as in the mask 1 (FIG. 1), even if the wearer inhales or exhales, the shape-retaining material in the covering portion (right covering portion 511 and left covering portion 512) The positional relationship between the vicinity portion of (531, 532) and the wearer's nostrils and mouth is maintained with almost no change. As a result, it is possible to avoid a situation in which a part of the covering portion (511,512) approaches or sticks to the nostrils or the mouth each time the sucking motion is performed. That is, the mask 5 can also reduce the painful sensations such as suffocation and heat when worn.

Further, if the shape-retaining material (531,532) is designed so that the maximum portion of its own width firmly hits the inner surface of the bag-shaped portion, it has a wavy end edge, so that it can move up and down. It is stably fixed in the bag-shaped mounting portion 51A without shifting in the direction. As a result, the effect of reducing the painful sensation during wearing can be stably achieved, and it is also possible to provide a better wearing feeling because it is not necessary to give the wearer a sense of discomfort due to misalignment. Further, even when the upper end of the bag-shaped mounting portion 51A is opened so that the shape-retaining material (531,532) can be taken in and out (detachable), the stored shape-retaining material (531,532) is intended. It is possible to avoid the situation of jumping out without doing so as much as possible. On the other hand, the shape-retaining material (531,532) having a wavy long side is inserted (stored) into the bag-shaped mounting portion 51A or taken out from the bag-shaped mounting portion 51A without imposing a large load. You can also do it.

As described in detail above, in the mask of the present invention, the shape-retaining material is attached by the attachment portion along the center line in the vertical direction. As a result, even if the wearer of this mask inhales or exhales, the positional relationship between the portion near the shape-retaining material in the covering portion and the wearer's nostrils and mouth is maintained with almost no change. It will be done. As a result, it is possible to avoid a situation in which a part of the covering portion approaches or sticks to the nostrils or the mouth each time the sucking motion is performed. That is, according to this mask, it is possible to reduce the painful sensations such as suffocation and heat when worn.

In particular, in situations where there is concern about the spread of viral infections, it is quite possible to wear a mask for a long time even in the summer when going out, but even in such a case, wear this mask. This makes it possible to contribute to the prevention of heat stroke, for example.

It should be noted that all of the embodiments described above are exemplary and not limited to the present invention, and the present invention can be implemented in various other modifications and modifications. Therefore, the scope of the present invention is defined only by the scope of claims for utility model registration and the equivalent scope thereof.
