Description

  The present invention relates to a mask that covers a user's mouth.

  Traditionally, masks covering the user's mouth, nasal cavity, etc. are used in various situations such as when catching a cold, when a dentist or surgeon performs a procedure, or when performing construction or machining. Used in. In particular, in recent years, it has been used for pollen countermeasures, and its versatility tends to expand more and more.

  Conventionally, masks used in various situations have also been conventionally formed by stacking a plurality of rectangular gauze or nonwoven fabric, etc. to form a main body, and rubber straps for ear hooks are attached to the left and right ends of the main body. Most of them were only attached to the ring. However, this conventional mask has a problem that the gauze comes into contact with the user's mouth, and the gauze gets wet as the usage time becomes longer, so that it is difficult to breathe from the mouth.

  Therefore, in recent years, so-called three-dimensional masks that have been three-dimensionally molded in the manufacturing stage so that the main body portion does not come into contact with the mouth have gained popularity. However, some people say that the three-dimensional mask has a poor appearance because of its unique shape. In particular, pollen masks, whose demand has increased significantly in recent years, will be used in towns and workplaces, so the apparent problem is important, and it is not possible to use them for that reason alone. Some people.

  So, for example, while using a conventional mask as a base, the problem that mouth breathing is difficult to be solved by superimposing a plastic net on gauze or non-woven fabric that constitutes the main body and strengthening the stiffness There is a proposal to try (see, for example, Patent Document 1).

However, even if plastic nets are overlapped, the shape of the main body during use is only as designed in advance. Therefore, there is a situation where the user's mouth and the shape around the user's mouth, which are very different, may not be suitable, and the problem that mouth breathing is difficult has not been completely solved.

  According to the present invention, it is a mask in which the appearance is not bad and the problem that mouth breathing is difficult is completely solved.

Next, an embodiment of the present invention will be described.
[Basic structure]
1 and 2 show a mask 11 of this embodiment. The mask 11 mainly includes a main body 2 that covers a user's mouth and nasal cavity during use, and a locking portion 3 for locking the main body 2 to the face.

  The main body 2 has a plurality of pleats 6 (an heel formed by zigzag folding) along the width direction, and rubber straps for ear hooks as locking portions 3 are attached to both sides in an annular shape. . The number of pleats 6 is not particularly limited, but 2 to 3 is preferable.

  In this embodiment, when the upper end and the lower end of the main body part 2 are pulled apart from each other in the width direction intermediate part of the main body part 2, the pleats 6 expand so that the intermediate part bulges outward, and the cup as a whole. It deforms into a shape. Therefore, when the main body 2 in this state is applied so as to cover the wearer's mouth and nasal cavity as shown in FIG. 3, the body part 2 usually has a space around the mouth and nasal cavity. The shape around the user's mouth and nasal cavity is various, and as described above, the user does not always have a space.

  As the shape of the main body 2, an appropriate shape such as an ellipse or a rhombus can be adopted in addition to a rectangle as shown in the illustrated example. Moreover, although the main-body part 2 of this form has the pleat 6, as shown in FIG. 12, the simple form which abbreviate | omitted the pleat 6 is also employable, for example.

  Furthermore, as shown in FIG. 2, the main body 2 of the present embodiment includes an inner sheet 2B facing the user's mouth and nose tip, an outer sheet 2A laminated on the outer surface of the inner sheet 2B, and these inner sheets 2B. And a shape maintaining member 2C interposed and fixed between the outer sheets 2A. Out of these members 2A, 2B, and 2C, the outer sheet 2A is not an essential member and can be omitted. However, if the outer sheet 2A is not provided, the shape retaining member 2C is exposed on the surface, and the appearance is apparent. Since it worsens, it is better to have 2 A of outer sheets like this form from a design viewpoint.

  The size of the main body 2 can be determined as appropriate and is not particularly limited. For example, when the pleat 6 is provided, the length of the pleat 6 can be 60 to 110 mm and the width can be 80 to 180 mm without expanding.

  On the other hand, the locking portion 3 of the present embodiment is a type in which an annular rubber string is hooked on the ear, but both side portions of the main body portion 2 are connected by a belt-like member, and the belt-like member is hung around the head, the neck, or the like. A locking type can also be employed (not shown). Examples of this type of locking portion include those disclosed in Japanese Patent Application Laid-Open No. 9-313631. In this case, the outer sheet 2A (or the inner sheet 2B) and the engaging portion 3 are integrally formed as a single member, and the inner sheet 2B ( Alternatively, the outer sheet 2A) can be laminated.

  Further, the outer sheet 2A and the inner sheet 2B, or an intermediate sheet appropriately interposed between them, should be a functional sheet having a dust filtering function, an aroma function, a virus / allergen inactivating function, an antibacterial function, and the like. You can also. In the case where the sheet having such a function is an intermediate sheet, it is also a preferred form that the sheet is detachably attached to the main body 2.

[Characteristic structure]
(First example)
As shown in FIG. 4, the main body 2 of the present example includes, as a shape holding member 2 </ b> C, a band-shaped member 9 that can be arbitrarily changed in shape, such as a metal foil such as a wire, polyethylene resin (Forte: Sekisui Chemical), and aluminum foil. Prepare. The belt-like member 9 is arranged so as to extend longitudinally along the horizontal axis center line of the main body 2, and more preferably to extend vertically through the user's mouth 8 (up and down in the drawing). Therefore, the main body 2 can be changed to an arbitrary shape and held (maintained) so as to conform to the user's mouth 9 and the surrounding shape of the user, which makes it difficult to breathe the mouth. The problem can be solved completely. In addition, when the belt-like member 9 is provided as in the present embodiment, the main body 2 is provided with the pleats 6, and when the intermediate portion in the width direction bulges outward and deforms into a cup shape as a whole, the function of retaining this deformed shape Also fulfills. This function is greater than when a plastic net is interposed. Further, when the belt-like member 9 is provided as in the present embodiment, the amount of bulging of the main body 2 can be minimized, and the shape is balanced with the shape of the user's mouth 9 and its surroundings. So that the problem of poor appearance does not occur.

  In the present embodiment, the number of the band-like members 9 extending longitudinally through the user's mouth 8 is one, but the present invention is not limited to this. For example, two, three, four, or more can be used. In addition to the belt-like member 9 extending longitudinally through the user's mouth 8, a belt-like member extending in another direction, a plastic net, and the like are also arranged at the same time. 2C can also be configured.

  In addition, although the strip | belt-shaped member 9 cuts the horizontal-axis centerline of the main-body part 2 vertically, as a form which does not extend by extending a user's mouth 8 vertically (paper surface up-down direction), the strip-shaped member 9 is the main-body part 2 for example. The form etc. which extend in the one or both side edge part of this can be illustrated.

(Second example)
In the first example, the band-like member 9 extending longitudinally through the user's mouth 8 is arranged at the center in the width direction (on the line passing through the nose 7). For example, as shown in FIG. In the range of the width direction range L where the person's mouth 8 is located, it can also be biased and arranged on the left and right sides, in the illustrated example, on the left side of the page. However, it is easy to solve the problem that mouth breathing is difficult to arrange in the center in the width direction, and the shape of the main body 2 is easy to be natural.

(Third example)
In the first and second examples, the band-like member 9 is simply arranged so as to extend across the user's mouth 8, but at least the mouth 8 from the user's nose 7 as shown in FIG. In the illustrated example, it can be arranged so as to extend vertically through the mouth 8 through the nose 7 from above the user's nose 7 so as to extend longitudinally. That is, in this example, the upper end edge of the belt-like member 9 is positioned within the range M from the upper end edge of the main body 2 to the lower end edge of the nose tip 7. According to this example, the space around the nasal cavity can be formed into an arbitrary shape, and nasal breathing can be facilitated. Moreover, the main-body part 2 can be made into a more natural shape than the 1st and 2nd example.

(Fourth example)
As described above, in the first to third examples, the band-like member 9 extending vertically through the user's mouth 8 is arranged vertically (in a direction perpendicular to the mouth 8), but is arranged obliquely. You can also In particular, as shown in FIG. 7, it is preferable that the band-like members 9 are arranged so as to extend in a square shape by vertically cutting the mouth 8 from both sides of the nose tip 7 which is the vicinity 7 </ b> A of the user's nose tip. It becomes. According to this example, since the space around the mouth 8 can be secured widely in the width direction, it is easier to solve the problem that mouth breathing is difficult, and the main body 2 (the inner surface of the inner sheet 2B) It can also prevent lipsticks and the like from sticking. In addition, the main body 2 can be easily formed in a more natural shape.

(Fifth example)
As described above, in the first to fourth examples, the belt-like member 9 is arranged so as to extend vertically through the user's mouth 8, but as shown in FIG. It can also be arranged in a net shape. According to this example, since the shape of the main body 2 can be finely adjusted, the problem of difficulty in mouth breathing can be solved more completely, and the main body 2 can be made more natural. be able to.

  In this example, a plurality of strip-shaped members 9 are combined to form a grid, but instead, for example, a metal foil or plastic such as aluminum in which a large number of openings are formed is prepared as the shape holding member 2C. As shown in FIG. 12, the shape holding member 2C can be inserted between the outer sheet 2A and the inner sheet 2B. According to this method, manufacture becomes easy.

  Moreover, as a form similar to this form, for example, as shown in FIG. 13, a metal such as aluminum in which a large number of holes 9a, 9a,... A flat member such as foil or plastic is prepared, and the flat shape holding member 2 </ b> C can be exemplified as a form provided to cover the periphery of the mouth portion 7 of the user.

(Sixth example)
As described above, in the first to fifth examples, the case where the belt-like member 9 is applied to the horizontally long rectangular main body 2 has been described as an example, but the present invention is not limited to this. For example, as shown in FIG. 9, the present invention can also be applied to the main body 2 having a shape in which the upper edge 2 </ b> A is bent downward and does not cover the user's nose 7. The arrangement of the band-like members 9 in FIG. 9 is the same as in the first example.

(Seventh example)
In addition to the above, the belt-like member 9 is formed in a cross shape, for example, as shown in FIG. Applications such as arranging things that extend across can also be made.

(Eighth example)
When arranging the belt-like member 9 as described above, as shown in FIG. 10, a plurality of belt-like members 9, 19... Are provided, and at least one of the belt-like members 19 is located above the nose 7 of the user. It is more preferable if it is arranged so as to extend across. If this belt-like member 19 is not disposed, a gap 20 is formed between the nose tip 7 or above and the main body 2 as shown on the left side of FIG. There is a risk of clouding or pollen. On the other hand, when the belt-like member 19 is arranged, the main body 2 can be made to follow the nose 7 and the shape above it as shown on the right side of FIG. Therefore, there is no fear of the above.

  The band-shaped member 9 is basically for preventing the mouth breathing from being difficult, that is, for separating the main body 2 from the face, whereas only the band-shaped member 19 is provided for the main body. 2 is close to the face, and it should be noted that the intended function differs greatly.

[Material constituting each member]
(Main body)
The material of each layer (sheet) of the main body 2 can be determined as appropriate. For example, a breathable material having an air permeability of 300 g / m ² · hr or more as defined in JIS Z 0208 can be used.

  Examples of such a material include a porous sheet having a large number of transmission holes, a net material, short fibers or long fiber aggregates such as woven fabrics and nonwoven fabrics, and laminates thereof.

  When using a fiber assembly, what the raw material fiber is is not particularly limited. Examples include synthetic fibers such as polyethylene and polypropylene such as olefins, polyesters and polyamides, recycled fibers such as rayon and cupra, natural fibers such as cotton, and mixed fibers in which two or more of these are used. can do.

  Furthermore, when using a nonwoven fabric, what was manufactured by what kind of processing may be sufficient. Examples of the processing method include known methods such as a spunlace method, a spunbond method, a thermal bond method, a melt blown method, a needle punch method, and an air through method. In addition, in order to improve the performance of blocking pollen and fine dust, it is also possible to use a laminated nonwoven fabric having a layer made of ultrafine fibers (diameter of about 0.5 to 5 μm) such as SMS nonwoven fabric or SMMS nonwoven fabric. it can.

  However, it is preferable that at least a part of the inner sheet 2B where the end of the belt-like member 9 is located, preferably the whole part, is formed of a melt blown nonwoven fabric. The part where the end of the belt-like member 9 is located has a greater friction with the user's skin than other parts, and is likely to fluff. However, since the melt blown nonwoven fabric is excellent in smoothness, the use of the melt blown nonwoven fabric at such a site prevents fuzz. In addition, it is preferable that such a part simultaneously contains a moisturizing component such as glycerin.

  When using a fiber assembly, the basis weight can be 15 to 70 gsm, particularly 20 to 50 gsm. If the basis weight is less than 15 gsm, a problem is likely to occur in strength. In particular, there is a possibility that tearing may occur if the locking portion 3 is repeatedly mounted. On the other hand, if the weight per unit area exceeds 70 gsm, the texture may be impaired, and it may become difficult for the user to squeeze or rub against the user's skin.

(Locking part)
The material of the locking portion 3 can be selected from the same material as that of the main body 2, but it is preferable to select a material that is rich in elasticity and elasticity and has little irritation to the skin.

  For example, by laminating a nonwoven fabric on both the front and back sides of an elastic stretch film and heat treating a laminated nonwoven fabric that has been subjected to stretch improvement processing such as needle puncture processing as needed, or a web made of heat-crimpable composite fiber In addition to the stretchable nonwoven fabric obtained, a pair of nonwoven fabrics can be bonded together, and a stretchable nonwoven fabric in which an elastic stretch member such as thread rubber is sandwiched between the nonwoven fabrics can be suitably used. Of course, other than these, for example, rubber such as flat rubber and round rubber can be used. Furthermore, a material obtained by combining these materials and a material that can be used in the main body 2 by lamination or the like can be used as the locking portion 3.

(Other)
The members and the layers (sheets) can be joined to each other by a known joining means such as heat sealing, hot melt adhesion, ultrasonic welding, or the like.

  The present invention is applicable as a mask that covers a user's mouth.
