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.

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.

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 (13, 13', 13'') attached along the "vertical center line" (FIG. 1) at the covering portion (right covering portion 111 and left covering portion 112). It is provided with a shape-retaining material (13, 13', 13'') having higher rigidity than the forming material of the covering portion (right covering portion 111 and left covering portion 112).
(D) The shape-retaining material ((13, 13', 13'') provided on or near the center line (FIG. 1) is attached to the covering portion (right covering portion 111 and left covering portion 112). It is characterized in that it is provided with a mounting portion for this purpose (bag-shaped mounting portion 11A in FIG. 1). Hereafter, the “vertical center line” in (C) above is a curve extending substantially vertically. The center line of the shape shall also be included.

As described above, in the mask 1, the shape-retaining material (13, 13', 13'') of the above (C) is attached along the center line (FIG. 1) by the attachment portion (bag-shaped attachment portion 11A). ing. As a result, even if the wearer of the mask 1 inhales or exhales, the portion near the shape-retaining material (13, 13', 13'') in the covering portion (right covering portion 111 and left covering portion 112) , The distanced positional relationship between 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 (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 (13, 13', 13'') is a forming material for the covering portion (111, 112) so that the shape can be maintained by the force normally received by the mask 1 when worn. It is made of a material with higher rigidity. Specifically, the shape-retaining material (13, 13', 13'') is made of polypropylene (PP) resin, polyethylene terephthalate (PET) resin, polyvinyl chloride (PVC) resin, or polyethylene (PE) resin. On the other hand, 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 (13, 13', 13'') may be cut out from the synthetic resin sheet as described above, or may be a molded product of the synthetic resin. it can.

Here, PP resin and PET resin, which can be used as a forming material for the shape-retaining material (13, 13', 13''), have the required rigidity and are safe enough to be used as a material for food containers. 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 and store the 11A (and the bag-shaped mounting portions 21A, 21A', 31A and 51A described later).

However, of course, the shape-retaining material (13, 13', 13'') 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 force normally received by the mask 1 when worn.

Further, as shown in FIG. 1, both the shape-retaining material 13 and the shape-retaining material 13'in the present embodiment are bent with a ridge line extending in the vertical direction (extending direction of the shape-retaining material). 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 of getting close to or sticking to the nostrils and mouth. Here, the cross section of the shape-retaining material 13 and the shape-retaining material 13'in the lateral direction (width direction) is V-shaped, but of course, the cross section is not limited to this, and is, for example, W-shaped or U-shaped. May be good.

Further, as a shape-retaining material to be attached (inserted) to the bag-shaped attachment portion 11A, a flat plate-shaped shape-retaining material 13'' having no bending can be adopted. The shape-retaining material 13 ″ is easier to insert into the bag-shaped mounting portion 11A and to be taken out from the bag-shaped mounting portion 11A because there is no bending. Here, the shape-retaining material 13 ″ may have a curved plate shape or a rod shape. The shape-retaining materials 13 ″ and the shape-retaining materials 13 and 13 ′ may have rounded corners for ease of insertion / removal and for safety (as shown in FIG. 1). preferable.

Further, unlike the shape-retaining material 13', the shape-retaining material 13 in the present embodiment has a curved shape as it advances in the vertical direction (extension direction). Therefore, by attaching (inserting and storing) such a shape-retaining material 13 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 13.

The shape-retaining material 13 shown in FIG. 1 is curved so as to include the back side of the ridge line inside (so that the ridge line becomes convex), but conversely, the ridge line is included inside (ridge line). May be curved (so that is concave). In any case, it is preferable that the shape-retaining material 13 is attached in a direction in which the inside of the mask 1 is recessed due to its curved shape.

On the other hand, the shape-retaining material 13'has a linearly elongated shape, but 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 13'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 material 13'. The shape-retaining material 13'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, the inside of the mask 1 It is also possible to attach it so that it faces.

Next, the attachment portion (D) is a bag-shaped attachment portion 11A in the present embodiment, although it is a part of the covering portion. 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 mounting portion 11A is closed by suturing, adhering, thermocompression bonding, or the like so that the shape-retaining material (13, 13', 13'') does not come out from the lower end. .. Here, the lower end of the bag may be closed after storing the shape-retaining material (13, 13', 13''), but in the present embodiment, the bag-shaped mounting portion 11A is the shape-retaining material (13). , 13', 13'') is attached (stored) in a removable form. Specifically, the upper end of the bag is left open, or the shape-retaining material (13, 13', 13'') is attached. Make a crease or catch on the upper end so that ")) does not easily pop out, and then pinch the shape-retaining material (13, 13', 13'') with your fingers so that it can be taken out of the bag. Is also preferable.

In any case, by taking out the shape-retaining material (13, 13', 13'') when not wearing, for example, the mask 1 can be folded into small pieces, the mask 1 can be washed by hand or by a dedicated device. Will also be easier.

The width of the shape-retaining material (13, 13', 13 ″) in the left-right direction (when stretched flat) 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 (13, 13', 13'') 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.

Next, the covering portion of the above (A) has a central mounting portion (bag-shaped mounting portion 11A) as a part thereof, but in the present embodiment, the right covering portion 111 is bordered by the center line (FIG. 1). And 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 contact cold sensation 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. 5). (Part separation / contact part), in this embodiment, the entire covering part
(A) A front surface showing a maximum heat absorption rate of a predetermined value or higher, and
(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. 5). 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). This also allows the wearer to select a more suitable wearing mode with less distress, for example, according to the season or environment.

Finally, the right mounting part 121 and the left mounting part 122, which are the mounting parts of the above (B), are parts composed of the same parts as the right covering part 111 and the left covering part 112, respectively, in the present embodiment. 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 around 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 changes have been made to the mask components such as the covering portion including the mounting portion, the mounting portion, and the shape-retaining material. Aspects are possible. In particular, the attachment portion is not limited to a bag shape such as the bag-shaped attachment portion 11A, and may be, for example, a string for binding and fixing the shape-retaining material, and a band for narrowing and fixing the shape-retaining material. It may be. Further, the shape-retaining material may have a pocket into which the tip of the shape-retaining material can be inserted, or a mounting portion for fixing the shape-retaining material using a hook-and-loop fastener can be used. Further, a hook-and-loop fastener, a double-sided seal, and other shape-retaining materials arranged between the part on the center line (Fig. 1) or the part along the center line and the shape-retaining material in the covering part can be directly attached to the covering part. It is also possible to adopt the means of the above as a mounting portion.

However, as the mounting portions, the bag-shaped mounting portion 11A described above, the bag-shaped mounting portion 21A (FIG. 2), the bag-shaped mounting portion 21A'(FIG. 3), and the bag-shaped mounting portion 31A (FIG. 3) described in detail later. By adopting 4) and the bag-shaped mounting portion 51A (Fig. 6), it is possible to construct the parts only with the cloth material, which makes the manufacturing relatively easy, and the shape-retaining material can be easily removed. It will be possible.

FIG. 2 is a schematic view showing another embodiment of the mask according to the present invention.

The mask 2 of the present embodiment shown in FIG. 2 is
(A) Right covering part 211 and left covering part 212, which are covering parts,
(B) A right mounting part 221 having an opening 221a and a left mounting part 222 having an opening 222a, which are mounting parts for fixing the right covering part 211 and the left covering part 212 to the wearer's head. ,
(C) A shape-retaining material (23, 23', 23'') attached along the vertical center line (FIG. 2) at the covering portion (right covering portion 211 and left covering portion 212), which is the covering portion. It is provided with a shape-retaining material (23, 23', 23'') having higher rigidity than the forming material of (right covering portion 211 and left covering portion 212).
(D) The covering portion (right covering portion 211 and left covering portion 212) is an attachment portion for attaching a shape-retaining material (23, 23', 23'') provided along the center line (FIG. 2). It is characterized in that it is provided with a bag-shaped attachment portion 21A.

Here, each of these parts / parts is formed by the same or similar material / manufacturing method as the corresponding parts / parts having the same name in Mask 1 (FIG. 1), and has the same or similar structure / shape. It is a part / part that can take the same or similar modification mode, fulfills the same or similar function / role, and exerts the same or similar effect. In particular, the shape-retaining materials 23, 23'and 23'can be the same as the shape-retaining materials 13, 13' and 13'' (FIG. 1), respectively.

However, in the mask 2 of the present embodiment, unlike the mask 1 (FIG. 1), the bag-shaped attachment portion 21A, which is a part of the covering portion, is
(A) The first cloth part and the second cloth part and the second cloth part (the inside of the mask 2 is bent so as to be recessed) that the end side opposite to the opening (221a, 222a) is curved toward the outside. Cloth parts (Fig. 2) and
(B) A bag-shaped part extending along the center line (Fig. 2) formed by suturing, adhering, or thermocompression bonding a vertically long third cloth part (Fig. 2) that is a part of the bag. ing.

More specifically, as shown in FIG. 2, the bag-shaped attachment portion 21A of the present embodiment aligns the curved ends of the first cloth part and the second cloth part, and sew (or sew) the ends thereof. After bonding or thermocompression bonding), the third cloth part of (b) above is pressed so as to cover the seam (or the line bonded or thermocompression bonding) by the stitching from the inside, and further, the upper and lower parts of the third cloth part are pressed. The end on the right ear side that extends in the direction and the first cloth part are sewn (or glued or thermocompression bonded), while the end on the left ear side that extends in the vertical direction and the second cloth part of the third cloth part. And are formed by stitching (or bonding or thermocompression bonding). Here, in this case, a bag into which the shape-retaining material can be inserted and stored is formed between the first cloth part and the second cloth part and the third cloth part that have been sewn (or bonded or thermocompression bonded). ..

As a result, the bag-shaped mounting portion 21A can have a shape that is bent so that the inside of the mask 2 is recessed, and the mask 2 can also be a so-called three-dimensional mask with an improved wearing feeling. It becomes.

Here, it is also preferable to attach (insert / store) the shape-retaining material 23 having a bent shape to such a bag-shaped attachment portion 21A in the bent direction. Alternatively, the linearly extended shape-retaining material 23'or the flat plate-shaped shape-retaining material 23'is attached (inserted / stored) to the bag-shaped attachment portion 21A, and the shape-retaining material 23'or the flat plate-shaped shape-retaining material 23' '' May be used in a bent state according to the bent shape of the bag-shaped mounting portion 21A. Further, as the shape-retaining material, for example, a curved plate-shaped or rod-shaped material having no bending can be adopted.

Of course, as for the bag-shaped mounting portion 21A, 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 2, for example, it becomes easy to fold the mask 2 into small pieces, wash the mask 2 by hand, or wash the mask 2 with a dedicated device.

(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. 5). 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 mounting portion placed on the wearer's auricles hardly change their positions on the face, the "part" is 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 "covering portion separation / contact portion" described above 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.
