Description

The present invention relates to a mask, and more specifically, to a mask that secures a wide mouth space when worn.

In recent years, masks have been used worldwide for the purpose of preventing droplet infection of infectious diseases. Such masks are used for various purposes such as measures against droplet infection of infectious diseases (that is, measures against viruses), measures against pollinosis, measures against colds, dust prevention, and measures against cold, and are used for industrial, medical, household, etc. It is widely used in the above applications.

Many of the masks have a shape that follows the contour of the face, and in particular, the pleated part that has been bent (pleated) so that it becomes a curved shape by expanding it in the vertical direction of the face. Masks with pleats are also provided. For example, in Patent Document 1 (Japanese Patent Publication No. 52-15893), in a flat paper / cloth mask main body having mounting strings at both ends, the central region of the main body is folded back substantially parallel to the upper and lower sides thereof as appropriate. A mask has been proposed in which a number of folds are provided and the main body is pulled up and down to increase the surface area during use.

Further, in Patent Document 2 (Japanese Patent Publication No. 61-11454), the conventional flat mask cannot surely cover the periphery of the mouth and nostrils, and in particular, a gap is generated between the peripheral portion and the face. In addition, in view of the problem that it is difficult to breathe because it gets wet with the moisture of the exhaled breath and adheres to the lips and nostrils, making it difficult to breathe, a sheet-shaped breathable material is formed to form multiple folds. Fold it in a long and narrow shape in the lateral direction, form fixing parts at both ends, attach a mounting rubber cord to the ends, and provide a shaping auxiliary member made of a flexible and shape-retaining material in the center of the upper fold. We are proposing a sanitary mask.

Jitsukaisho 52-15893 Jitsukaisho 61-11454

As described above, a mask provided with a plurality of pleats so as to develop in a shape along the curved shape of the face (hereinafter referred to as "pleated mask") has been provided. However, since the pleated masks conventionally provided have a plurality of pleats arranged in the height direction of the mask, they are curved in a gentle convex shape over a wide range, and are formed in the wearer's mouth or the like. It was difficult to secure a large space.

Therefore, the first object of the present invention is to provide a mask that can secure a wide space in the wearer's mouth and the like when worn, and more preferably, can secure a large distance between the mouth and the mask in the space. And.

Further, the sanitary mask described in Patent Document 2 is formed by folding a sheet-shaped breathable material laterally into an elongated shape by a plurality of folds or the like, but since the entire mask is folded, the face is worn when worn. It is difficult to maintain the unfolded state of the mask when wearing it because it is not possible to cover the vertical direction of the mask widely and the rubber cord for mounting is provided at one place at both ends of the folded fixing part. there were.

Therefore, the present invention provides a mask that can cover a wide range of the face in the vertical direction when worn, can reliably maintain the deployed state, and can secure a wide space around the mouth. , The second task is different from the above task.

Further, the sanitary mask described in Patent Document 2 is provided with an orthopedic auxiliary member made of a material having flexibility and shape retention in the center of the upper fold, and when used, the orthopedic auxiliary member is pinched to the nose muscle. By matching the shape, the mask body is designed so that only the peripheral edge touches the face and covers the mouth and nose. However, this technique requires an auxiliary member for shaping, which increases the number of processing steps and increases the manufacturing cost.

Therefore, the present invention aims to provide a mask that bends along the wearer's nose and has improved adhesion to the face at the edges without using such a molding auxiliary member. This is another third issue.

In order to solve at least one of the above problems, the present invention provides a mask that can be widely deployed in a direction away from the wearer's face.

That is, in the present invention, in order to solve at least one of the above problems, a main body portion made of a breathable cloth and covering at least the wearer's mouth and nostrils, and a mounting portion for attaching the main body portion to the wearer The main body of the mask is formed with a folded portion in which creases extend in the left-right direction, and the folded portion is formed by folding the cloth constituting the main body so as to overlap four or more layers. A flat portion having no crease is formed in the vertical direction of the folded portion, and the mounting portion provides a mask provided on the flat portion.

In the mask of the present invention, the main body is a cloth made of a woven fabric, a knitted fabric, a non-woven fabric (including paper) and the like, and is formed at least with breathability, and may further include a filter. Further, it is desirable that the folded portion is formed by bending so that four or more layers, preferably seven or more layers of cloth constituting the main body portion overlap, and the number of overlapping layers may be an odd number.

In the present invention, the folded portion can be formed at one place in the vertical direction in the main body portion. Further, the folded portion can be formed so as to exist within a range from the center to the bottom in the vertical direction of the main body portion of the mask.

The upper edge of the main body may be provided with ridges and concaves so as to be easily bent along the nose when worn. That is, in the central portion of the upper edge portion of the main body portion, a ridge that protrudes outward and extends in the vertical direction when worn can be formed. Further, on the outside of the ridge, a dent that is depressed outward when worn and extends in the vertical direction can be provided. These ridges and / or concaves can be formed so that the upper edge of the mask body bends along the nose. The ridges can be formed so that the upper edge of the main body of the mask is bent in a mountain fold along the nose, and one ridge is formed in the center of the left and right sides of the main body of the mask, and two ridges are formed. It can also be arranged in parallel at predetermined intervals. Further, the concave shape is formed so as to form a valley fold along the shape of the base portion where the nose portion protrudes. Such a concave shape can also be formed by one or two or more.

Further, in the present invention, the folded-back portion can be folded back with different folding widths so as to overlap four or more layers. In the folded part to be stacked, when the folded part is unfolded when worn, the folded width is widened from the top to the bottom, the folded width is narrowed from the top to the bottom, and the folded part is folded in the center part rather than in the vertical direction. The width can be widened, or the folding width of the central part can be narrower than in the vertical direction. That is, by making the folded width different for each layer in the folded and laminated fabric, the curved shape when the folded portion is unfolded can be made different.

In the above-mentioned mask according to the present invention, the main body is made of cloth such as cotton, linen, gauze, and can be formed by using a non-woven fabric, and is further used in existing industrial, medical, or household masks. It can be made of various materials. Further, the mounting portion is an ear hook portion (ear hook cord) made of a rubber cord or flat rubber for attaching the main body portion to the wearer, and a head that wraps around the back of the head and fixes the main body portion to the wearer. It may be a part plate, a belt or a string.

The mask of the present invention is not necessarily limited to the one used for the purpose of measures against droplet infection of infectious diseases (that is, measures against viruses), and is used for various purposes such as measures against pollinosis, colds, dust, and cold. can do.

The mask of the present invention is made of a breathable cloth, and is a mask including a main body portion that covers at least the wearer's mouth and nostrils and a mounting portion that attaches the main body portion to the wearer. The folded portion is formed so that the crease extends in the left-right direction, and the folded portion can be greatly bulged because the fabric constituting the main body portion is folded so as to overlap four or more layers. It is possible to secure a wide space between the wearer's face and the wearer's face. Therefore, according to the present invention, it is possible to realize a mask that can secure a wide space in the wearer's mouth and the like when worn, and more preferably, secure a large distance between the mouth and the mask in the space.

Further, since a flat portion having no crease is formed in the vertical direction of the folded portion, the wearer's face can be covered even in the upper and lower ranges of the inflated region. This makes it possible to obtain a mask that can cover a wide range while securing a wide space at the tip of the nose and the mouth, that is, a wide space in the direction away from the face.

Further, since the mounting portion is provided on the flat portion, the mounting portion can act in the direction of expanding the folded portion when the folded portion is spread and worn. Therefore, it is possible to obtain a mask that can cover a wide range in the vertical direction of the face when worn and can reliably maintain the deployed state.

Further, in the mask according to the present invention, when the folded portion is formed at one place in the vertical direction in the main body portion, only the region where the folded portion is formed can be expanded by unfolding.

Then, in the central portion of the upper edge portion of the main body portion, a ridge extending in the vertical direction that protrudes outward when worn is formed, and on the outside of the ridge, the vertical direction that is depressed outward when worn is formed. By providing a dent that extends to the mask and bending the upper edge of the mask body along the nasal muscles by the ridges and / or dents, a member for shaping the shape along the nasal muscles is not used. It is possible to realize a mask that is bent along the wearer's nose and has improved adhesion to the face at the edges.

Further, in a mask in which the folded portion is folded back with different folding widths and overlaps with four or more layers, the curved shape at the time of unfolding can be adjusted depending on the position of the folded portion and the folded width, and is therefore arbitrary. It can be a mask that can be expanded into a curved shape.

Hereinafter, the mask 10 according to the present embodiment will be specifically described with reference to the drawings. In particular, this embodiment shows an embodiment of a sanitary mask for home use, but it is naturally possible to embody it as a mask for industrial use or medical use.

FIG. 1 is a rear view of the mask 10 according to the first embodiment (A) and a cross-sectional view taken along the line XX (B), and FIG. 2 is an exploded perspective view of the mask 10 according to the first embodiment. FIG. 3 is a side view showing a wearing state of the mask 10 according to the first embodiment.

The mask 10 according to the first embodiment shown in FIGS. 1 to 3 is composed of a main body portion 30 that covers the wearer's mouth and nostrils, and a wearing portion 20 for attaching the main body portion 30 to the wearer. The mounting portion 20 is formed by using an ear hook cord made of a rubber cord. The main body portion 30 is formed by using a cloth (including paper) such as a woven fabric or a non-woven fabric, and is formed to have breathability in order to secure the breathing of the wearer. The main body portion 30 is formed with a folded-back portion 31 in which the crease extends in the left-right direction. In particular, in the mask 10 according to the present embodiment, the folded portion 31 is formed in the central portion in the height direction of the mask main body portion 30, and the folded portion 31 is expanded in the vertical direction to form a bellows shape and worn. It can be curved and projected so as to secure a space from the person's nose to the chin.

It is desirable that the folded-back portion 31 is formed by folding back the fabrics constituting the main body portion 30 so as to overlap four or more layers, and in the present embodiment, the folded fabrics constituting the main body portion 30 are folded back so as to overlap the seven layers. The folded-back portion 31 is formed. By folding the cloth so that four or more layers are overlapped (the cloth is four layers) in this way, when the folded portion 31 is expanded and formed into a bellows shape, it can be curved in a wide range. As a result, it is possible to secure a wide space (particularly, a space having a wide distance between the face and the inner surface of the mask) between the wearer's face and the inner surface of the mask 10 when worn.

The number of times the fabric is folded back in the folded-back portion 31 may be arbitrary, and preferably, by overlapping the fabrics at an odd number, the flat portion 34 described later can be formed into a sheet shape extending in the vertical direction. Further, the folding width and the number of foldings of the cloth in the folded portion 31 can be arbitrarily adjusted according to the curved shape when unfolded. That is, if the folding width and the number of foldings (the number of layers to be stacked) are increased, the separation distance from the face when the folded portion 31 is unfolded can be increased to project the folded portion 31, and a wide space at the mouth can be secured. On the other hand, if the folding width and the number of foldings are reduced, the distance from the face when the folding portion 31 is expanded can be reduced, and the space around the mouth can be narrowed.

Further, in the mask 10 according to the first embodiment, the folded-back portion 31 is provided substantially in the center of the main body portion 30 of the mask in the vertical direction. As a result, when the folded-back portion 31 is unfolded, it can be evenly curved and projected in the vertical direction from the central portion of the mask 10. However, the folded-back portion 31 may be provided in a range above the upper and lower centers of the main body portion 30 of the mask, or in a range below the upper and lower centers of the main body portion 30 of the mask. For example, when the bellows-shaped curved portion that expands and appears the folded portion 31 is formed in the vicinity of the nose tip, the folded portion 31 can be formed above the upper and lower centers of the main body portion 30 of the mask. Further, when the bellows-shaped curved portion is formed in the vicinity of the mouth, the folded portion 31 can be formed on the lower side of the upper and lower centers of the main body portion 30 of the mask. In particular, in order to prevent the wearer's lipstick or the like from adhering to the inside of the mask 10 main body, it is desirable that the vicinity of the mouth portion bulges in a curved shape to form a wide space.

Further, in the present embodiment, the folded-back portion 31 is formed at one position in the vertical direction in the main body portion 30 of the mask. As a result, the folded-back portion 31 can be expanded so as to bulge outward at one place where the folded-back portion 31 is formed. However, the folded-back portion 31 can be formed at two or more locations so as to be parallel in the vertical direction, and in that case, the region forming the folded-back portion 31 can be curved in a bellows shape by unfolding.

Then, in the mask 10 according to the present embodiment, a flat portion 34 having no crease is formed in the vertical direction of the folded portion 31. By providing such a flat portion 34, when the folded-back portion 31 is unfolded and worn, the flat portion 34 can be expanded along the wearer's face, whereby the inner surface of the mask and the wearer's face are in close contact with each other in a wide range. Sex can be ensured. That is, the mask 10 according to the present embodiment secures a sufficient space between the wearer's face and the inner surface of the mask in any area such as the tip of the nose and the mouth, while other areas, particularly the main body of the mask. In the edge region of 30, the mask 10 with improved adhesion to the wearer's face can be used.

A mounting portion 20 is provided on the edge of the flat portion 34 of the main body portion 30 of the mask so as to be vertically connected vertically on the left and right sides. In the present embodiment, the mounting portion 20 is formed by an elastic ear strap, but it can also be formed by a belt or a string. Further, the mounting portion 20 may be provided so as to be connected to the left and right in the vertical direction of the mask 10 main body. That is, the wearing portion 20 can be used without particular limitation as long as the main body portion 30 of the mask can be held at a predetermined position on the face of the wearer.

An example of the structure of the main body 30 of the mask according to the present embodiment will be described with reference to FIG. In the present embodiment, the main body sheet 35 is formed of a single layer or laminated by using a cloth, a filter, or the like, and the reinforcing band 32 is formed by folding the upper and lower edges of the main body sheet 35 into a band shape. In addition, this reinforcing band may be integrated by suturing, heat welding, adhesion or the like along the upper and lower edges of the main body sheet 35 with another band-shaped member. The main body sheet 35 is folded up and down so that the folds extend in the left-right direction in order to form the folded-back portion 31, and the left and right edges are sewn, heat-welded, bonded, or the like in the folded state. , The folded portion 31 is formed. However, when forming the folded-back portion 31, only the left and right folded-back portions may be sewn, heat-welded, or bonded. At this time, the folded region can be sutured or heat-welded together with the flat portion 34, or can be sutured or heat-welded separately from the flat portion 34. In particular, in the latter case, the folded portion can be made upright in a direction orthogonal to the flat portion 34, and as a result, the folded portion 31 projects from between the upper and lower flat portions 34 toward the front side. It can be 10.

The main body sheet 35 configured as described above has its upper and lower edges folded back to form a band-shaped reinforcing band 32. The reinforcing band 32 can be formed to reinforce the upper and lower edge portions of the main body 30 of the mask and to be molded so as to be easily curved into an arbitrary shape. For example, the reinforcing band 32 can be formed on the upper part of the main body 30 of the mask so as to be easily bent along the wearer's nose. In the present embodiment, as shown in FIG. 1C, the reinforcing portion is provided with ridges 33a protruding outward (depressed inward) in the center in the left-right direction, and on the outside of each ridge 33a in the left-right direction. A concave groove 33b that is depressed (protruding inward) to the outside is provided. When viewed from the outer front of the mask 10, the ridge 33a functions as a guide for easily folding the upper edge of the main body 30 into a mountain fold, and the concave ridge 33b valley folds the upper edge of the main body 30. It can function as a guide to make it easier to fold. However, at least one of the ridges 33a and the ridges 33b can be formed by two grooves arranged in parallel. For example, two or more ridges 33a may be arranged in parallel in the center of the main body 30, and two or more ridges 33b may be arranged in parallel on the outside of the two or more ridges 33a. can.

Then, as described above, the above-mentioned reinforcing band 32 is formed on the upper edge portion and the lower edge portion of the main body sheet 35 folded so that four or more layers of cloth are overlapped, and the above-mentioned reinforcing band 32 is attached to the inside of the folded reinforcing band 32 with an ear strap. The end portion of the portion 20 is sandwiched. The mask 10 is formed by integrating the main body sheet 35 and the mounting portion 20 by stitching, heat welding, adhesion, or the like. In particular, in the mask 10 according to the first embodiment shown in FIGS. , And the mounting portions 20 are arranged at the left and right ends of the main body sheet 35 in the vertical direction, and the reinforcing band 32 can be folded and sewn to simplify the manufacturing process. Can be done. The reinforcing band may be provided with a separate band-shaped member along the upper and lower edges of the mask body, and the reinforcing band may be integrated by stitching, heat welding, adhesion, or the like.

Next, the mask 10 according to the second embodiment will be specifically described with reference to FIG. FIG. 4 is a vertical cross-sectional view showing the mask 10 according to the second embodiment, and a side view showing a wearing state. The mask 10 according to this embodiment is formed as a mask 10 in which the folded portions 31 are formed at two positions in the height direction of the mask 10 main body. In the present embodiment, the two folded portions 31 are arranged so as to face each other, and a first (upper) folded portion 31 is formed from the lower end of the flat portion 34 facing the nose portion when worn. After that, a second (lower) folded-back portion 31 is formed so as to form a flat portion 34 facing the jaw portion when worn. However, the two folded portions 31 may be provided with a flat portion 34 between the folded portions, and three or more folded portions 31 may be formed. However, it is desirable that each folded portion 31 is formed so that four or more layers of folded fabrics overlap each other. This is because the bulging width at the time of unfolding can be increased by folding the layers so as to have four or more layers at one place. In the folded and laminated fabric, at least any part of the folded layers may overlap each other. This is because if the number of layers is quadrupled or more in one place, the amount of swelling can be increased and a large space can be secured between the swelling amount and the wearing surface of the wearer.

In the mask 10 in which the two folded portions 31 are arranged so as to face each other as described above, when the mask 10 is unfolded, the central folded portion (a portion extending in the left-right direction in a strip shape and referred to as a “belt-shaped portion 36”) is used. A bellows-shaped part can be made to appear in the vertical direction at the boundary and can be developed so as to be curved. That is, the upper and lower bellows-shaped portions allow the band-shaped portion 36 existing between the folded portions to bulge in the direction away from the wearer's face, thereby ensuring a wider space (a space having a large bulging amount). can.

In particular, in the mask 10 according to the second embodiment, the facing folded portions 31 can be formed with different folding numbers and / or folding widths, and the band-shaped portion 36 existing between the folded portions is arbitrary. It can be formed in a width (length in the vertical direction of the mask 10 main body). By changing the folding width and the number of foldings of the folding portions 31 existing above and below, it is possible to adjust the depth of the space secured between the face and the inner surface of the mask, and the band-shaped portion secured between the folding portions. The width of 36 allows the vertical width of the space to be adjusted. Therefore, according to this second embodiment, the mask 10 can be made into a mask 10 in which the size of the space secured between the inner surface of the mask 10 and the face of the wearer can be freely adjusted.

Next, the mask 10 according to the third embodiment will be specifically described with reference to FIG. 5A and 5B are a vertical sectional view showing a mask 10 according to a third embodiment, and a side view showing a wearing state. The mask 10 according to this embodiment is formed so that the folded width of each layer in the folded portion 31 is different. That is, in this embodiment, the folded width of the region existing on the chin side of the wearer at the time of deployment (hereinafter referred to as “upper region 31a”) is set to the region existing on the nasal side of the wearer at the time of deployment (hereinafter referred to as “upper region 31a”). , "Lower region 31b") is formed so as to be narrower (for example, about 1/2) than the folding width. In particular, in the present embodiment, the upper region 31a is configured to overlap the three layers, and the lower region 31b is configured to overlap the four layers. However, the number of layers can be arbitrarily changed, and the upper region 31a may be configured to overlap one layer, and the lower region 31b may have five layers or the like.

In the mask 10 configured in this way, when the folded-back portion 31 is unfolded, the upper region 31a can be curved in a gentle curve, and the lower region 31b can be curved in a sharp curve by a fine bellows. That is, by setting the folding width of each layer in the folding portion 31 to at least two types in this way, it is possible to obtain the mask 10 capable of changing the degree of bending at the time of deployment in the vertical direction.

In addition, in relation to the mask 10 according to the present embodiment, the folding width at the folding portion 31 is at least one of a region facing the nose portion, a region facing the mouth portion, and a region facing the chin portion at the time of deployment. Can be formed shorter than other regions, and can be appropriately changed according to the purpose of use.

The mask of the present invention secures a large space in and around the mouth of industrial, medical, and household masks used for anti-virus measures, anti-hay fever measures, cold measures, dust-proof measures, cold-proof measures, etc. It can be used to improve comfort when worn.
