Description

Mask and its manufacture 5t¾ "method Sickle field

The present invention relates to a mask covering the nose and mouth.

Back-As this type of mask, for example, sanitary masks, dust masks, masks for use, etc. are known.Specifically, they are worn for the purpose of preventing pollen suction and suction or release of pathogenic bacteria. As a conventional sanitary mask, a mask body made of a flat gauze with an ear hanging string is generally used. However, this mask had a problem that it was difficult to breathe when worn.

For this reason, recently, a mask with an AL cup inside the mask body (see, for example, Japanese Patent Application Laid-Open No. 9-2766424), or a bellows-shaped mask body in which the fabric is folded in a pleated shape are placed on the shelf. Masks that can easily breathe by forming a space under the nose in the mounted state, such as a mask that inflates outward sometimes (for example, refer to Japanese Patent Application Laid-Open No. 2001-310450), are mounted. It is becoming. However, in the former case, »masking increases the number of manufacturing processes, which increases the cost. In addition, the mask moves toward the eyes when the chin is moved up or down by talking or gumming while wearing the mask. There was also a problem that the mask was easily displaced, and the displaced mask had to be pulled down by hand each time to return to the original position, which was troublesome. In the latter case, the production took time and the power design was not good. In addition, in these conventional masks, a gap force s is formed between a portion of the mask that rises from both sides to the bridge of the nose when the mask is worn and a force S such as a flower particle or a pathogenic bacterium easily enters the inside of the mask from this gap. Since the gap becomes large when it is lowered, it cannot be said that the penetration of pollen and the like into the nose and mouth is sufficiently blocked by a mask to be a rale.

Therefore, one of the main objects of the present invention is to perform breathing easily and easily and at low cost. A mask that can be manufactured and its manufacturing method of 5t ”.

Another main object of the present invention is to provide a mask in which a gap is not formed between a portion which rises to the bridge of the nose from both types when worn and the mask. Another main object of the present invention is to provide a mask which is hard to be displaced even when the chin is moved up and down when worn.

Disclosure of the invention

In order to achieve the object as described above, a mask according to the present invention is made of cloth, includes a mask body that covers at least a mouth and a nose, and a pair of ear hooks. Oka which absorbs the fabric in at least one of the vertical direction, the horizontal direction and the diagonal direction, forms a breathing space inside when worn, and turns the fabric forward ^^ and holds it. It has a 胜 part.

In other words, in the mask of the present invention, the Oka I portion protrudes forward at the center of the mask body, thereby forming a recess inside the rigid 14 portion, and the user's nose is in the recess. The nose is not pressed down by the mask body, and the respiratory space force s is formed under the nose so that breathing can be performed easily.

Best mode to practice

In the present invention, if the fabric of the mask main body is formed of Nitozo having an outer fabric portion and an inner fabric portion, the bulging shape of the Oka IJ portion is further reinforced and the outer shape is further improved. Flowers from! ^ It is possible to further prevent the ftA of pathogens and the release of pathogens to the outside.

In the present invention, the top of the rigid portion is formed at a higher position than the middle position in the vertical direction. If the mask is worn from the side, the upper part of the seam is inclined along the nose muscle, the top coincides with the position of the nose, and the mask is inclined toward the chin from the top down. Since it has a shape, it is preferable as a mask having an excellent design property that matches the line of ». As will be described later, the rigid portion may be formed of a sewn portion or an adhesive portion of the fabric, or a wire, rubber, soft synthetic resin, shape memory resin, or any of these materials inserted in the mask body. It may be a core material composed of a composite material obtained by selecting at least two of the above.

In the present invention, if a filter is provided inside the mask body, a filter capable of adsorbing and removing, for example, fine flower pathogens or fine particles (for example, fine particles of tobacco smoke, fine particles of exhaust gas, etc.) is provided. It is preferable because it can be stored and exchanged.

Further, it is preferable that at least the portion in contact with the lips is made of a material that moves moisture to the outside of the mask, so as to reduce stuffiness inside the mask. Positiveness is imparted to the part in contact with the lips.

In the present invention, the Ifj property part may be constituted by a stitched part or a bonded part of the fabric. In this case, the mask body may have a specific configuration as described in the following (1) and (2).

(1) The mask body becomes the left fabric part that constitutes the left half surface and the ^ ground part that constitutes the right half surface, and the rigid part is not strong. The vertical stitching line or adhesive line is composed of a stitching line, jointing portion, or joint that is bent forward so that a respiratory space can be formed inside with the left fabric part and the other part open and the wearing part is open. It may be something.

When the left fabric portion and the bottom portion of the mask are opened, the vertical stitching portion or the adhesive portion formed in the middle of the mask body in the left and right directions swells forward, and the dents inwardly upward and downward. The dent is formed in the dent, and the nose is held by the mask body. Can not be held down, and a spatial force for breathing is formed under the nose so that breathing can be easily performed. Also, since the left fabric portion and the ground portion are simply stitched or bonded to form a mask body that expands three-dimensionally outward, the number of members does not increase, and the cap X is bonded. In addition, the mask can be easily manufactured at low cost without much trouble. Further, the left fabric portion and the M fabric portion are overlapped and overlapped with each other, and the joined portion or the bonded portion becomes a swelling, a bulged shape of the joined portion or the bonded portion. The left fabric portion and the W fabric portion are thin, and the upper IBS Peng Lami shape is formed even if the fabric is thin. Furthermore, since a material such as a napping material is not used for forming the swelling shape of the stitched portion or the bonding portion, and the whole is made of cloth, it can be easily washed as it is, and when stored, It can be neatly folded in half at the seam or glued.

Further, in the case of the above configuration (1), each of the left fabric portion and the right fabric portion is composed of two or more divided fabric portions, and these are sewn or adhered, and the bending force S differs for each divided fabric portion. It may be configured as follows. With this configuration, it is easy to form the mask main body into a shape that swells outward three-dimensionally, and it is possible to form a wider respiratory space around the nose and mouth.

(2) The mask body is composed of divided fabric parts divided into a plurality of upper and lower sheets, and the rigid part is formed by sewing or bonding the upper ttif self-divided fabric part and the lower Ι Ι divided fabric part to each other. The left and right stitching lines or bonding lines are formed by stitching or bonding portions curved forward so that a breathing space can be formed inside with the upper and lower divided fabric portions opened and worn. Is also good.

When the upper and lower divided fabric parts of this mask are opened, the left and right stitching parts formed on the mask body or the swelling part bulges forward, forming a dent on the inside of the mask. The nose is not held down by the mask body while the nose force ^s is absorbed, and the respiratory space force S is formed under the nose so that breathing can be easily performed. Also, a mask book that swells three-dimensionally outward simply by simply stitching or bonding the upper and lower divided fabric parts together Since the body is formed, the number of points does not increase, and the force ¾MX does not require much labor for bonding, and the mask can be easily manufactured at low cost. In addition, the stitched portion or the bonded portion that is sewn by overlapping the edges of the upper and lower divided fabric portions together and sewn together forms a swelling shape bone of the paired portion or the bonded portion to reinforce the shape. As a result, even when the upper and lower divided fabric portions are thin fabrics, the shape of the upper IBS Peng Lami is maintained. Furthermore, since the swelling portion or the swelling shape of the adhesive portion is not used for forming a swelling material, the entire structure is made of cloth, so that it can be easily washed and stored as it is. At times, it can be folded neatly at the joint or at the junction.

In addition, the configuration (2) (M) may be a configuration in which an intermediate divided fabric portion is provided between the upper and lower divided fabric portions.

Further, in the mask according to the present invention, the rigid portion may be a composite material formed by selecting at least two of wire, rubber, soft resin, shape resin 1 and the like held in the mask body. It may be a core material composed of Examples of the core material made of the composite material include a wire wire covered with rubber or soft synthetic resin. This core material is formed in a shape that is bent in a U-shape so that the top is located at a position higher than the middle position in the vertical direction at the neutral position in the horizontal direction of the mask body, and is formed inside the mask body. Inserted. In this case: ^, the mask body is formed in advance in the middle in the left-right direction; in the standing position, for example, a vertical insertion tube β having an opening at the upper end is formed in advance, or an opening is formed in one of the right ends. And a pre-formed tubular bag portion for centering in the left-right direction passing through the position where 麵 comes.

In this way, by constructing the Oka I 胜 part by:, the fabric can be easily curved and held forward simply by inserting the core material into the mask body, and as a result, the breathing space can be obtained. Can be formed, and the mask body can be simplified and manufactured with one piece of cloth. Note that it is preferable to use a shape memory alloy as the wire because the bulge shape of the mask body can be maintained for a long time. Further, in the mask of the present invention, the mask main body is formed of an O-shape force S stitched portion or an adhesive portion, or a core material, and a force-shape I-portion is formed in a vertical direction. Gears may be provided at both ends. In this way, the right and left ends of the mask body can be fitted to the left and right sides of the mask without any gaps while conforming to the shape and size of the user's face due to the expansion and contraction of the gears. Dust and particles can be reliably prevented from entering the inside from both left and right ends.

Further, the mask of the present invention is provided in a pair of right and left on the back side of the mask main body, and may be formed between a portion rising from both sides to the nose bridge and at least an upper edge of the mask main body when worn. The device may further include an upper closing member for closing the gap.

In other words, by closing the gap between the part that rises from both sides to the bridge of the nose and the mask with the upper closing material, it is possible to prevent the invasion of flower buds and pathogens from the upper edge of the mask, and to breathe more hygienically. I can do it.

As the upper blocking member, a sheet-like or lump (pad) -like member having elasticity, plasticity, or flexibility can be used. Specifically, the following configurations (3) and (4) can be mentioned. it can.

(3) The upper closing member is made of an elastic flap that is attached to the inside of the mask body on the back side of the mask body so that it can be folded back. For this elastic flap, for example, a sponge of 1 to 5 mm, cloth, a composite thereof, or the like can be used as a structure β-type material, and the inner ends near the left and right centers are folded when the flap is folded inward. For example, two elastic flaps formed in a desired shape such as a substantially trapezoidal shape, a substantially rectangular shape, a substantially triangular shape, a substantially elliptical shape, etc. Attach the mask on the back side of the mask body, near the upper β side, turn the upper end side inward, and attach the mask.Fold the elastic flap inward, and sew or glue at least the outer side to the inner surface of the mask in advance. Alternatively, it may be fixed.

(4) When the upper blocking member is positioned near the back of the mask body, It consists of a pad material attached. The pad material is preferably an elastic pad or a pad that can be deformed in response to an external force.Moreover, the pad material is integrally attached to the mask body. May be something. For example, a pair of left and right pockets forming a pad is provided at the position of the mask body, and a sponge body, a soft rubber body, a soft plastic body, etc. Put the body in and lay it in to form an elastic pad, or insert a bag filled with a powder, gel or liquid that maintains fluidity and sew it in to form a plastic pad. Alternatively, the pad may be formed by first inserting the elastic body or the bag into a cloth bag and sewing the pad material, and then sewing the pad material to the mask body later. As a detachable one, for example, an elastic body or a bag body is sewn to a pad material and a mask body by attaching an elastic body or a bag body to a cloth bag as shown in FIG. The upper pad material is attached to the mask body by hooking the hook part and the loop: ¾, and the upper pad material is removed from the mask body by detaching the hook part and ゾ-: ¾. The elasticity of the body used for the elastic flap or the elastic pad is such that the elasticity of the living body does not make it difficult to press even after putting on the mask for a long time, and it is possible to secure a sufficient occlusion He can do it! ^ Power s preferred. The powder constituting the plastic pad may be a powder or a granular material such as sand, titanium oxide, or aluminum silicate. The gel may be a carboxyvinyl polymer (carbopol), polyacrylic, or the like. MX can use salts thereof and the like, and silicon can be used as a liquid. In each case, a substance harmless to the human body is desirable.

Further, the mask of the present invention is provided near the lower surface of the back side of the mask body, near the fiber, and closes a gap formed between at least the lower part of the lower lip and the lower edge of the mask body when worn. It may be further provided with a member.

In other words, the lower jaw is formed between the lower part of the lower lip and the lower edge of the mask body when the mask is worn; When the mask is moved up and down, the lower blocking member will not slip and the mask This eliminates the inconvenience of manually correcting the rising of the mask as in the related art. The lower closing member may be a lower pad material attached near the lower basket on the back side of the mask body. The lower pad material is preferably a lower elastic pad or a lower pad that can be deformed in response to an external force. Further, the lower pad material is integrally attached to the mask body as described above, or is separate from the mask body. It may be removable. In addition, the lower elastic pad can be configured such that an elastic body such as a sponge body, a soft rubber body, a soft plastic body, or the like is laid in a cloth bag and put in the same manner as the above-mentioned upper closing member, while The plastic pad may have a configuration in which a bag body filled with powder, gel, or liquid that maintains fluidity in the same manner as the above-mentioned upper crane material is put in a cloth bag and sewn.

In the present invention, as the ear hanging part, an elastic rubber string having elasticity or an ear hanging string provided with an ft length adjusting member can be used. It should be noted that the rights of the string length adjusting member will be described in the following embodiment.

In addition, in the case where the ear hanging part is formed of an ear hanging string, the ear hanging string is bent at substantially the center of its width, and is sewn in a state where the upper and lower edges of the mask body are sandwiched. It may be attached by gluing or bonding. In other words, when a mask with ear straps attached to the inside of the left and right sides of the mask body is worn, the traces of the attachment parts of the ear straps are easily marked with 、, making such traces less likely to be attached.

Also, the mask of the present invention may be provided with an accessory force S on at least one of the mask main body, the ear hook portion, and the height adjusting member. In particular, in order to have a pregnancy adjustment to adjust the length of the ear strap, the purpose of this fineness adjustment is to hide or make it less noticeable, and to improve the mask in a design and fashion manner. For the purpose, an accessory power S is provided. The accessory may be, for example, a butterfly, a ripon, a gnot, a star, a flower, or the like made of a cloth, plastic, or the like in the form of a butterfly. And the like.

In addition, the mask of the present invention may be provided on either the outside or the inside of the mask body. A filter member having a filtration capacity capable of effectively covering 95% or more of fine particles in the air having a size substantially covering the outer surface or the inner surface and having a cap diameter of 0.3 m or more is further provided. May be used. Here, “the filtration capacity capable of cutting 95% or more of fine particles in the air having a diameter of 0.3 im or more” means “medical treatment of CDC (U.S. Centers for Disease Control); It refers to filtration capacity that complies with the “Guidelines for Prevention of Infection (1994)” (conforms to N95).

By providing such a filter member, microbes and fungi smaller than dust, dirt and flowers (for example, tuberculosis bacterium and pneumonia virus) can be removed by the filter member. It is effective in preventing and expanding dyeing.

Such a finoleta member is preferably detachably attached to the mask body because it is easily replaceable, and is detachably attached to the inside of the mask body. Just store it. In addition, in order to detachably attach the filter member to the outside of the mask body, a filter is housed between the mask cover and the mask body by further including a breathable mask cover detachably attached to the outside of the mask body. can do. As a method of attaching and detaching the mask cover to and from the mask body, a method of 5 | ¾ ^ such as a hook or a planar fastener can be used.

According to another aspect of the present invention, there is provided a mask for manufacturing a mask including a mask body having a left fabric portion forming a left half surface and a right fabric portion forming a right half surface, and a pair of ear hanging cords. It is illegal to make

The mask body is formed by laminating the left fabric piece and the ground piece together: the left fabric piece and the ^ Ϊ fabric piece are sewn or bonded to each other, and the line is sewn or bonded at the time of this stitching or bonding. There can be provided a method of manufacturing a mask in which the left fabric portion and the right fabric portion are opened and curved so that a respiratory space can be formed inside when worn.

According to yet another aspect, the present invention includes a divided fabric portion divided into a plurality of upper and lower sheets. Manufacturing a mask having a mask body and a pair of ear laces,

The mask body is formed by superimposing the upper and lower divided fabric pieces on the upper and lower divided fabric pieces ^ :, sewing, joining, or bonding the upper and lower divided fabric pieces to each other. At this time, there can be mentioned a method of manufacturing a mask in which a line to be sewn or a line to be bonded is curved so that a breathing space can be formed inside with the upper and lower divided fabric portions opened and worn. In addition, this: ^, upper and lower means that in addition to the upper and lower divided fabric portions, the divided fabric portion disposed in the middle is also included.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the form of the key.

FIG. 1 is a front view of a mask according to Embodiment 1 of the present invention, FIG. 2 is a plan view of the mask of Embodiment 1, and FIG. 3 is a rear view of the mask of Embodiment 1. FIG. 4 is a cross-sectional view taken along line AA of FIG. 1, and FIG. 5 is an explanatory diagram showing a use state of the mask of the first embodiment.

Mask M of Difficulty Form 1 is composed of a left fabric part 11 that has breathability suitable for breathing that constitutes the left half face when viewed from the front, and a right fabric part that has breathability suitable for breathing that constitutes the right half face 1 2 A left and right net portions 3, 3 provided on the left end side of the left fabric portion 11 and on the right side of the Φ ground portion 12 And a filter base 17 provided on the inner surface side of the mask body 1.

The mask body 1 has a left fabric portion 11 and a sewing portion 13 as a rigid portion in which the left fabric sound 1 and the left and right ^ -shaped fabric portions 12 are sewn to each other. The stitched portion 13 is bent forward so that a breathing space 16 can be formed inside when the left fabric portion 11 and the base portion 12 are opened and worn. In other words, when viewed from the side, the mask main body 1 is slightly higher than the middle position in the vertical direction, and bulges into a forwardly projecting mountain shape (see FIGS. 4 and 5) in which the tops 14 are arranged on the sewing line. I have. By forming the sewn portion 13 bulging forward (outward) in the middle position between the left and right of the mask body 1, the opposite face 15 is formed on the inner surface side of the mask body 1. The nasal force S of the person wearing the mask body 1 in the recess 15 can be accommodated (see Fig. 5). Therefore, the recess 15 forms the respiratory space 16 below the nose of the user, and the space 16 allows the user to easily breathe through the nose and / or the mouth. It is to be noted that the space 16 makes it easier to utter. In addition, when a general flat mask is worn, a gap is formed between the mask edge and the left and right sides of the nose muscle, from which the flower α の花⁵ pathogens in the open air enter the inside of the mask and inhale into the body. On the other hand, in the mask M of the present invention, no gap is formed in the mask 15 of the present invention because the recess 15 extends along the left and right !! In addition, the seam portion 13 is formed by overlapping the adjacent edges of the left fabric portion 11 and the right fabric portion 12 with each other.The force forms a swelling bone, and the swelling shape is captured. Thereby, even if the left fabric portion 11 and the right fabric portion 12 are thin fabrics, the bulging shape is formed.

Further, the left fabric portion 11 and the left fabric portion 12 are respectively divided by the outer fabric portions 11a and 12a, the inner fabric portions 11b and 12b, and the power of Nitozo. The left fabric portion 11 and the right fabric portion 12 may be made of breathable fabrics made of various materials such as cotton, hemp, silk, and composite, but are not particularly limited. For example, the material of the inner and outer surfaces may be changed such that the outer fabric portions 11a and 12a are made of cotton cloth, and the inner fabric portions lib and 12b are made of total β »| Or it may be the same. In addition, in the mask の of the present invention, the color of the outer fabric portion 11a, 12a is selected from various colors such as blue, red, yellow, and other primary colors and intermediate colors in addition to general white. The image may be erased to add fashion.

The pair of left and right ear hooks 2, 2 is made of a flat rubber cord, and is sewn and attached to the left and right edges of the left W ground portions 11, 12 of the mask body 1, respectively. The ear hooks 2, 2 can accommodate the size of the user's face due to the elasticity of the elastic cord, Therefore, the ears are tightened when wearing a mask so that the ears do not hurt even if worn for a long time. In addition, a rubber cord 3 a connecting the upper side and the lower side of each ear hook part 2 is provided near the mask body 1, and a space surrounded by each rubber cord 3 a, each ear hook part 2 and the mask body 1. The above-mentioned net part 3 is stretched. The net portions 3 and 3 improve the fit of the mask M to users and the like when wearing the mask, and also add design features.

The pocket-shaped filter portion 17 is opened upward by sewing the left and right edges and the lower edge of the pocket fabric portion 4 made of, for example, air-permeable cloth or netting to the inner peripheral edge of the mask body 1. It is formed in a shape. At least a portion in contact with the lips of the filter plate 17 is made of a material that moves moisture from the inside of the mask to the outside. Specifically, for example, a field sensor (trade name of Sekirei Co., Ltd.) is used. According to such a filter unit 17, stuffiness inside the mask can be reduced. Further, antibacterial properties are imparted to at least a portion of the filter portion 17 which is in contact with the lips. This: ^ For example, anti-bacterial property is imparted by applying silver plating to the intended part of the filter, or silver plating is coated! ^ | ゃ The filter holding part is made of fiber impregnated with popidone. They can be configured to provide antimicrobial properties to the whole.

The filter 7 includes, for example, a filter 18 capable of adsorbing and removing minute pollen, pathogenic bacteria (for example, tuberculosis bacteria, pneumonia virus), and fine particles (for example, fine particles of cigarette smoke, fine particles of exhaust gas, etc.). Contains a filter that complies with N95.

Note that, as an excellent filter capable of filtering fine flowers and the like, for example, Japanese Patent No. 3218480 can be mentioned. More specifically, it consists of a single layer of strand fabric of microfilaments having a cross-section in the direction of air flow passing through the filter of up to 30 microns, the strands being spaced up to 20 microns. , A filter having a smooth outer surface. Micro filament Materials for strands include polyester / ray, nylon, polypropylene, carbon, fiberglass, ceramic, and ^ S strands. This filter can remove allergenic pollen, which is generally larger than 20 microns. Such materials are commercially available. In addition, a plurality of holes having a diameter smaller than the minimum diameter of the fine particles to be filtered are formed in one single-layer sheet of the filtering material by laser power,

There are filters formed by X-ray lithography, chemical etching or stretching of microporous sheets. For drilling by laser cutting, X-ray lithography or chemical etching, it is possible to use “ii” as a raw material, and for drilling by stretching a microporous sheet, a microporous plastic sheet can be used as a filtering material. is there. This filter is used to filter particulates such as tapaco smoke particles and vehicle exhaust gas particles, and has a pore size of / J, 0.01 micron! ^

Further, apart from the above, a filter that is unnecessarily utilized by utilizing a line graft polymerization method can be suitably used for the mask of the present invention. For example, irradiation with radiation such as _α- rays, rays, γ-rays, electron beams, ultraviolet rays, etc., in addition to polyethylene, polypropylene, etc., generates radicals, which are then used to cause the graft monomer to become S. By introducing a more desired graft polymer side chain, a filter having a desired function can be manufactured.

As a specific example, by selecting bulpyrrolidone as the daraft monomer, it is possible to obtain a non-woven fabric having polyvinylpyrrolidone introduced therein, and further immersing it in iodine reservoir to form a nonwoven fabric with popidone odor attached thereto, thereby obtaining an antibacterial filter. Can be suitably used.

In addition, by selecting bininolebenzyltrimethylammonium chloride (VB TAC) as the graft monomer and further allowing an appropriate monomer to be used, it is possible to obtain a product into which VB TAC is introduced, which is preferably used as a pollen filter. be able to. Next, a method of manufacturing the mask body 1 of the mask M configured as described above will be described. Since the mask main body 1 has a double view as described above, the outside and the inside thereof are separately observed. In other words, the outer fabric portions 11a and 12a of the left fabric portion 11 and the fabric portion 12 are sewn together to form an outer member, and the left fabric portion 11 and the fabric portion 1 2 are formed. The inner fabric portions 1 lb and 1 2b are sewn together to form an inner member. Then, the mask body 1 is formed by overlapping the outer and inner members and aligning the peripheral edges thereof.

By the way, the outer individual J member and the inner member can be formed respectively as shown in the following (a) and (b).

(a) The left fabric piece and the mechanical fabric that compose the right fabric section 12 are formed by the left and right sides of the left and right fabric pieces. Predetermined shape, curved into a shape,

The formed left fabric piece and «fabric piece are overlapped and sewn along the edge of the shape of. By doing so, the left fabric piece and the fabric piece can be easily stitched to the desired line shape only by stitching along the edge curved in the shape of a triangle.

(b) In (a) above, the edges of the left fabric piece and the other piece that are difficult to make are straightened.
