JP 2002-345986 A JP-A-10-248948 Japanese Patent Application No. 2003-144631 JP-A-10-277171

  In recent years, an increasing number of people are suffering from allergic respiratory disorders such as hay fever, and an increasing number of people are wearing masks when going out, as in the spring season. Under such circumstances, masks using various shapes and high-performance filters have been developed and marketed.

  The nasal cavity wearing nasal mask described in Patent Document 1 has a configuration in which C-type frames equipped with filters are connected in opposite directions, which are inserted into the nasal cavity and worn.

  However, even in the same person, the size of the nasal cavity on the left and right is not necessarily the same, and it is impossible for everyone to share a nasal mask mass-produced to a certain size. Cannot be inserted into the nasal cavity, or the mucous membrane of the nasal cavity may be damaged. On the other hand, a nasal mask smaller than the nasal cavity cannot be retained in the nasal cavity and easily falls off.

  Even if it can be attached to the nasal cavity, if the degree of close contact is low, a gap is generated and the expected effect cannot be achieved. Moreover, it must be said that there is a considerable foreign body feeling and the wearing feeling is very bad.

  The mask of Patent Document 2 is in contact with the skin in order to increase the degree of adhesion to an uneven face, and an adhesive is attached to the outer periphery of the mask. However, when the skin muscles move during conversation, the skin is pulled by the adhesive. The face is dragged and the fit is bad. In addition, displacement occurs when worn for a long time, and the adhesive is peeled off from the skin while the position is being corrected, and the adhesion is impaired. People with sensitive skin may experience rough skin caused by adhesives. Also, the mask is usually removed indoors or during customer service, and the mask may be attached and detached several times a day. Each time, the adhesive material must be peeled off and the mask removed, which is painful and can be expected to significantly reduce the accuracy of the adhesive material. If the effect of the adhesive material is weakened and the adhesion to the skin cannot be secured, the desired effect cannot be achieved.

  Originally, if the mask is uneven, it covers the face where the muscles move up, down, left, and right, so pollen in the mask is better than the performance of the filter in order to maximize the original filter effect of the mask. It is necessary to prevent as much as possible. On the other hand, the high-performance filter has high ventilation resistance, making it difficult to breathe and the feeling of wearing is poor. In addition, the dust mask formed three-dimensionally becomes large, and many people hesitate to wear it because it is too large. Since the ventilation resistance is low, it is easy to breathe, but a mask with a high pollen control rate when worn is considered an ideal mask. In addition, a mask using an electrostatic filter or a high-performance filter formed in multiple layers becomes expensive, and it is economically difficult to purchase a large number of masks that are used every day during a long period of pollen scattering.

  Therefore, the applicant of the present application reduces the gap between the mask and the face as much as possible, is detachable, has a low foreign object feeling, is easy to use, and is inexpensive, and the mask auxiliary tool of Japanese Patent Application No. 2003-144431, This led to the creation of the aid.

  However, since the mask assisting tool and the cloth covering the nose are sewn to the mask body, the position of the nose mask and the like is fixed at one place, and the degree of freedom in selecting the desired position for each person is low.

  The mask described in Patent Document 4 is a mask formed with a bottomed bag and is filled with an impregnating material such as a gauze impregnated with a fragrance or a chemical solution. At the same time, the medicine is inhaled into the nostril. However, if the impregnating material has the same shape as the mask, the weight of the mask itself becomes heavy. If the impregnating material is impregnated with a drug, it is difficult to position the impregnated part on the nose or mouth. If you are away from your nose or mouth, you cannot expect the effect.

  Accordingly, an object of the present invention is to provide a mask that facilitates positioning of the nasal mask, enhances the wearing feeling and adhesion, and further increases the removal rate of pollen and the like at low cost.

  It is another object of the present invention to provide a mask assisting device that further enhances the effect of collecting pollen and the like by bringing a roll-shaped gauze impregnated with a drug into contact immediately below the nasal cavity.

  After folding the substantially rectangular cloth, the peripheral edge is sewn except for a part of the long side, and planar fasteners are attached to both ends to form a nasal mask.

  Next, a patch is sewn on the short side of the substantially rectangular mask body, one end of the mask strap is sewn to the mask body at one end of the patch, and the surface fastener is attached to the other end. A mask body is formed in which the other end of the attached mask strap is freely hooked.

  The planar fastener sewn on the nasal mask and the planar fastener of the strap of the mask body are locked, and the nasal mask is attached to the inside of the mask body so as to be freely attached and detached.

  Further, a roll gauze in which a gauze cloth is wound is impregnated with a glycerin aqueous solution or the like, and then fixed with an adhesive gauze and mounted in a mask to form a double structure mask.

  Since the mask body has a double structure in which a nasal mask is installed, first, pollen can be removed by the mask body, and infiltrated pollen can be completely removed by the nasal mask.

  In other words, the gap when the mask is worn is in the nose bridge and nose nose where the highest difference in the face occurs, and in consideration of the pollen falling from above, pollen can be prevented from entering through the gap. This is the most effective way to increase the removal rate. The double structure mask of the present invention can suppress the inhalation of pollen entering from the gap between the face and the mask, which has been a defect of the conventional mask, by incorporating a nasal mask in an ordinary mask.

  The conventional product using fine cloth to increase the collection efficiency has problems such as high ventilation resistance and difficulty in breathing. However, since the present invention has a double structure, the inner cloth has a coarse cloth. Can be used, and respiratory problems are less likely to occur.

  In addition, the nasal mask is attached to the nasal bridge and does not block the nostril, so it is easy to breathe and is convenient to use as a mask that must be worn for a long time.

  By attaching a wire to the upper part of the mask body and the upper part of the nasal mask, it is possible to make the face more uneven, and to prevent pollen from entering the mask more effectively.

  In addition, since the length of the hanging strap can be adjusted, the nasal mask can be positioned according to the user, and there is no gap between the mask and the nasal bridge feeling. Therefore, the inner mask is not displaced and there is no need to correct the position.

  Since the adhesive is not intended to enhance the adhesion, it is easy to correct the position even if the mask body or the nose mask is misaligned.

  Appearance is a general-purpose mask, there is no resistance to wearing, it can be freely attached and detached, and it is easy to use as a mask that can be removed and attached many times a day.

  The structure is simple and can be manufactured at low cost. In other words, considering that it is used every day at the time of pollen scattering over several months, it is hygienic and economical if it can be purchased in large quantities. Furthermore, since the nasal mask to be brought into close contact with the nose can be removed, the nasal mask can be disposable, and it is more hygienic and economical.

  The pollen collection rate can be further increased by bringing the roll gase into contact with the nasal cavity directly under the nasal cavity in the mask and impregnating the roll gase with a drug.

 Example 1

  Next, the best embodiment of the double structure mask of the present invention will be described with reference to the drawings.

  FIG. 1 is an explanatory view showing a state of the nose mask 1 that is an inner part of the mask having the double structure according to claim 1 before sewing the peripheral portion, and FIG. 2 is a perspective view of the nose mask 1.

  The nose mask 1 is formed by folding two pieces of gauze cloth 2 having both edges 2 a cut into a mountain shape, overlapping them, sewing a peripheral edge other than the ring portion 2 b, and folding it at a valley fold line 5. At this time, a portion having a mountain shape is defined as an upper cloth 3 and a lower half as a lower cloth 4. Surface fasteners 6-6 are sewn in advance near both ends of the back surface 4a of the lower cloth 4.

  The peripheral edge processing is performed by leaving the short side 8-8 of the peripheral edge of the folded gauze cloth 2 and the central portion of the long side 7 as an opening.

  By stitching in this way, a three-dimensional pocket 9 is formed in which the mountain-shaped portion 2a of the upper cloth 3 rises and covers the nose.

  The method of sewing the nasal mask is not limited to the above-described method, and darts, gathers, and the like may be applied as long as the pocket covering the nose can be formed three-dimensionally.

  Next, the mask main body to which the nasal mask 1 formed in this way is attached will be described. FIG. 3 is an explanatory diagram showing a mask body sewing method, and FIG. 4 is a perspective view of the mask body 10.

  The mask 10 uses a gauze cloth as in a normal mask, and is formed by sewing four pieces of gauze cloth cut into a trapezoidal shape as shown in FIG.

  Two trapezoidal gauze cloths 11-11 (the left half of the mask) and 12-12 (the right half of the mask) are centered, and the hypotenuses 11a-11a, 12a-12a are overlapped and stitched to form a cylinder. 11b-12b, which is the lower side of the trapezoid, is stitched to form a cylindrical mask body 10 having openings 11c and 12c. This is turned upside down to expose the surface, and while the darts 15 and 16 are being taken, 11c and 12c are folded, and the straps 13 and 14 are sewn.

  At this time, the other end 17a of the rubber cord 17 having a planar fastener 18 attached to the tip is sewn to one end 13a of the abutting cord 13, and a snap (female) 21 and a snap (male) 22 are sewn to the other end. is there.

  Similarly, the other end 19a of the rubber cord 19 with the surface fastener 20 attached to the tip end is sewn to the one end 14a of the other strap 14, and the snap (female) 23 and the snap (male) 24 are sewn to the other end. I will stop.

  Thus, the mask main body 10 having a three-dimensional structure covering the nose and cheeks with the mask central portion 25 having a middle height is formed.

  The method of forming the mask main body is not limited to the above-described method, and the gauze cloth may be gathered as long as the center has a three-dimensional structure with a middle height.

  FIG. 5 is an explanatory view showing a state in which the nasal mask 1 is attached to the mask body 10.

  The nasal mask 1 is attached to the mask body 10 by engaging the surface fasteners 18 and 20 sewn on the rubber strings 17 and 19 with the surface fastener 6-6 attached to the nasal mask 1.

  FIG. 6 is an explanatory view showing a method of mounting the double structure mask. The mask user 26 removes the snaps 22 and 24 of the mask straps 13 and 14 and inserts the nose 27 into the nasal pocket 9 of the nasal mask 1 to cover around the nasal bridge and the nasal cavity. The elastic cords 17 and 19 are pulled while hanging on the ears 28 to 28, and the nasal mask 1 is attached to the face as much as possible. Thereafter, the rubber strings 17 and 19 are stopped by the snaps (21, 22) and (23, 24) attached to the contact strings 13, 14, and the mask body 1 covers the nose mask 1 and the mouth 29.

The material of the mask body and nasal mask is not limited to gauze. The material of the mask body and nasal mask is a combination of gauze, cotton and gauze, or a high-grade water-based cloth. It is possible to adapt to uses such as pollen removal or runny nose absorption. It is also possible to use a refreshing type containing a fragrance or a virus removal filter.
Example 2

  Next, another embodiment of the double structure mask will be described.

  The present invention relates to a mask in which a wire is housed in a nose mask and a mask body, the wire is bent in accordance with the shape of the nose, and the adhesion is further improved.

  The mask 30 has a double structure of a nose mask 32 and a mask body 31.

  The nose mask 32 is formed by folding two pieces of gauze cloth having both edges cut into a chevron shape and overlapping them, and sewing both edges to form a cylinder. The wire 49 placed at the center of the chevron end is covered with a cloth piece 50, and the wire is attached to the portion of the nasal mask 31 that contacts the nasal bridge.

  A planar fastener 35-35 is sewn in advance in the vicinity of both ends of the back surface of the lower cloth 34 to which no wire is attached. Next, the gauze cloth is folded in half, and the peripheral portion is sewn with the opening left, to form the nose storage pocket 33.

  Next, the mask body 31 sews a pair of cylindrical gauze cloths 36 and 37, then folds the opening edges 40 and 41 while removing the darts 38 and 39, and presses them with the straps 43 and 44 to sew them. At this time, the end portions of the rubber cords 45 and 46 are sewn with the contact cords 43 and 44, and the surface fasteners 47 and 48 are sewn to the other ends of the rubber cords 45 and 46. A snap (not shown) is attached to one end of the contact strings 43, 44 so that the rubber strings 45, 46 can be freely detached. The wire 51 is placed on the center upper portion of the mask body 31 formed in this way, covered with a cloth piece 52, and the periphery is sewn, so that the wire 51 is built in the mask body 31.

  The wire attached to the nasal mask and the mask main body enhances the adhesion to the face and closes the upper part of the mask to further prevent pollen from entering.

In addition, by using elastic rubber straps, it is possible to flexibly adapt to the size of the user's face, and since the rubber straps are flat, tightening on the ears when wearing a mask is eased. Even if worn for a long time, the ear does not hurt.
Example 3

  In the third embodiment shown in FIG. 8, the inner mask 52 is formed larger than the nasal mask of the first embodiment so as to cover both the nose and the mouth.

  A gauze cloth having a pair of sides is folded and sewn at the periphery, and after further folding, a part is left as an opening and sewn to form a pocket for storing the nose and mouth.

  The inner mask 52 is fitted to the face while the nose and mouth are stored in the pocket 53 of the inner mask, and the outer mask 55 is attached to form a double structure mask to enhance the pollen removal effect. The wire 54 may be provided in the inner mask 52 so that the mask is not displaced.

  FIG. 9 is a perspective view of a roll gauze and a contact gauze which are auxiliary tools for the mask according to claim 2. FIG. 10 is an explanatory view showing a state where the mask auxiliary tool is actually mounted. Roll gauze 57 is a cylindrical shape having a diameter of about 2 cm by winding a gauze cloth having a width of about 3 cm. The nose and mouth are covered by pressing with a gauze 56, and a mask is attached so as to hold the edge of the abutment gauze to form a double structure.

  The size, shape, etc. of the roll gaze and the contact gauze are not limited as described above. Therefore, the mask assisting tool composed of the roll gaze and the contact gauze can be changed in size and mounted in the nasal mask which is the inner mask according to claim 1.

  The drug impregnated in the roll gaze is not limited to glycerin, and may be a drug having a moisturizing effect or pollen collecting effect, a refreshing agent, or a fragrance.

  Although the present invention has a simple structure, it should be noted that it is effective. This time, in developing these mask aids and masks, we asked Nara Prefectural University of Medicine, Department of Chemistry, Assistant Ide to conduct an experiment in order to demonstrate the effects. As a result, a very high pollen control rate could be obtained. The experimental results and the apparatus used will be described below.

  FIG. 11 shows a pollen exposure apparatus used for verifying the pollen control effect of the mask and mask assisting device in the present invention. This device was developed by Assistant Professor Ide, Department of Chemistry, Nara Medical University. The paper “Development of cedar pollen scattering device for medical research” was published by “Environmental Technology Research Association”. "Environmental technology reprint" Vol. 32. No. 3

  The experimental results described below were also conducted under the supervision and direction of the assistant using this device.

  Reference numeral 60 denotes a pollen exposure device. The 61 pollen generator is a system in which a small amount of pollen adhering to an acrylic disk is sucked by an air ejector and transferred into the pollen exposure chamber 61 to be scattered. By changing the rotational speed of the disk, the amount of sucked pollen can be increased or decreased.

  The pollen disperser 62 uniformly drops the pollen in a spiral shape in the pollen exposure chamber.

61 pollen exposure room of a volume of about 1.3m ^3, pillars, all wall surface or the like can be dismantled, in response to the multi-purpose of the experiment, it can be modified. The subject 63 can sit on a chair with the floor surface crafted, and only the upper body can enter. Reference numerals 64 and 65 denote the head face of the person including the ears, which can be breathed through the nose or mouth. Reference numerals 66 and 67 denote devices for collecting inhaled pollen in water. It is collected by filtration and the number of pollen is counted with a microscope.

  68 and 69 are pollen meters. 68 is a type of intermittent suction (500 ml / time of suction for 1 second, 15 times / minute) imitating human breathing. 69 is a continuous suction (4.1 l / min) measurement type.

  Table 1 shows the number of pollen measured continuously for 120 minutes using the above-described pollen exposure apparatus 60 without a mask and using the double structure mask comprising the nasal mask and the mask body according to claim 1. Table 2 shows the number of pollen measured without a mask and with a non-woven mask.

  In this way, when the double structure mask is used, there is a significant difference in the number of pollen compared to the case of not using it, and the pollen hardly passes through the mask, and the pollen rejection rate of 99% or more is actually recorded. . In addition, the non-woven mask can reduce the number of pollen to one third, but the pollen rejection rate is only 70%.

  When the pollen removal rates of the nonwoven fabric mask and the double structure mask are compared in Table 3, the difference is clear.

  Table 4 shows this in a graph.

  Tables 5 and 6 are graphs showing numerical values of the effect of the double structure mask according to claim 1 as viewed from the number of intermittently sucked pollens.

  Even when a non-woven mask is used, the number of sucked pollen is certainly reduced compared to when no mask is attached, but when a double structure mask is attached, almost no pollen is sucked and the pollen removal rate is almost 100%. There is something close, and the high effect has been demonstrated.

  Table 7 shows changes in the number of pollen when the mask according to claim 2 is used and when it is not used. The “roll address gaze” described in the table is a mask auxiliary tool used for the mask according to claim 2 of the present invention.

  Table 8 shows changes in the number of pollen when the non-woven mask and the mask are not used. When the non-woven mask is worn, the number of pollen is reduced to about one third, but the pollen rejection rate is only 70%.

  Thus, there is a significant difference in the number of suction pollen when wearing a mask aid. Tables 11 and 12 are graphs of this.

  Table 9 compares the pollen removal rates of the nonwoven fabric mask and the roll addressing gauze. Thus, the pollen removal rate of the non-woven mask is only 70% to 80%, but the pollen removal rate for the roll gauze is close to 100%, and the mask assisting device according to claim 2, High effectiveness has been demonstrated.

  INDUSTRIAL APPLICABILITY The present invention can be used not only as a pollen removal mask but also as a mask for preventing airborne infections such as influenza and surges, because a nasal mask is provided in the mask body and has a double structure.
