FIG. 1 shows a perspective view of a mask 1 of the present embodiment, and FIG. 2 shows a view of the mask 1 in FIG. As shown in FIGS. 1 and 2, the mask 1 of the present embodiment is roughly divided into a mask main body 2, an ear hook 3, and an adherent member 10. The mask main body 2, the ear hook 3, and the adherent member 10 here correspond to the “mask main body”, “ear hook”, “adhered member”, and “mask adherent” in the present invention, respectively. is doing.

(Configuration of mask body 2)
The mask body 2 is configured as a part that covers the wearer's mouth and nose among the parts of the mask 1. As shown in FIGS. 1 and 2, the mask main body 2 is worn by joining a right sheet piece 2a covering the wearer's right face and a left sheet piece 2b covering the left face to each other by heat welding. The wear surface 2d on the person side is configured to be recessed. The wearing surface 2d here corresponds to the “wearing surface” in the present invention. In addition, a joining edge 2c extending in the longitudinal direction of the wearer is formed at the joining portion of the right sheet piece 2a and the left sheet piece 2b, and the mask body 2 borders the joining edge 2c. Divided into left and right. The right sheet piece 2a and the left sheet piece 2b referred to here correspond to “sheet pieces” in the present invention. Further, the mask body 2 is set in a three-dimensional shape when the mask is worn while the right sheet piece 2a and the left sheet piece 2b are set apart from each other as shown in FIG. When the mask is not used or when the mask is not used, the folded state (planar shape) in which the right sheet piece 2a and the left sheet piece 2b are in contact with each other is set. In addition, this mask main-body part 2 should just be made into a three-dimensional shape at least at the time of mask wear, and may be made into the same three-dimensional shape not only at the time of mask wear but before mask wear.

In this Embodiment, the mask main-body part 2, ie, the right side sheet piece 2a and the left side sheet piece 2b, are all formed using the nonwoven fabric of a thermoplastic synthetic fiber. As this thermoplastic fiber, polyethylene, polypropylene, polyethylene terephthalate, etc. are used. Air-through method, spun bond method, thermal bond method, spun lace method, point bond method, melt blow method, stitch bond method, chemical bond method, needle Those having a basis weight of 30 to 150 g / m ² manufactured by a punch method or the like can be used as appropriate. In addition, this non-woven fabric is breathable, has a good touch and feels good to wear, and is lower than the ear hook 3 so that the three-dimensional structure is easily retained when it is applied to the face. It is preferable to be stretchable. This nonwoven fabric corresponds to the “nonwoven fabric” in the present invention.

(Configuration of the ear hook 3)
The ear hooking portion 3 is configured to extend from the left and right sides of the mask main body portion 2, that is, from the respective end portions of the right sheet piece 2a and the left sheet piece 2b. Each ear hook 3 has a separate structure from the mask main body 2 and is configured to be partially overlapped and joined to the mask main body 2. Each ear hook 3 may be integrated with the mask body 2 as a part of the mask body 2. Each ear hook 3 is formed in a ring shape having an opening 3a. When the mask 1 is worn, the opening 3a of the ear hook 3 is hooked on the wearer's ear while the face of the wearer, in particular, the nose and mouth are covered with the mask body 2. The ear hook 3 is preferably formed of a non-woven thermoplastic synthetic fiber material similar to the mask main body 2 and having a stretchable material that does not hurt the ear. Specifically, a stretch layer (for example, a nonwoven fabric in which propylene continuous fibers are welded together) and an elastic layer (for example, heat A configuration in which non-woven fabric using elastic yarn made of plastic synthetic fiber elastomer, urethane, or the like is laminated can be suitably used.

(Configuration of deposition member 10)
The adherend member 10 is configured to extend in a strip shape (also referred to as “tape shape” or “plate shape”) in the left-right direction on the wearing surface 2 d of the mask main body 2. In particular, the deposition member 10 is configured to be detachable from a predetermined deposition area B on the wearing surface 2d side of the mask body 2. That is, the adhesion state (the state indicated by the broken line in FIG. 1 or the state indicated by the solid line in FIG. 2) in which the adherent member 10 is adhered to the adhesion region B on the wearing surface 2d side, and the wearing surface 2d side A desorption state (state indicated by a two-dot chain line in FIG. 1) removed from the deposition region B can be formed. In addition, this adherent member 10 may be previously attached to the attachment region B on the wearing surface 2d side of the mask main body 2 or when the mask is worn, the wear surface 2d of the mask main body 2 by the wearer. It may be applied to the side application region B. The deposition region B here corresponds to the “deposition region” in the present invention.

  3 and 4 will be referred to regarding the specific structure of the adherend member 10. Here, FIG. 3 shows a perspective view of the adherent member 10 in FIG. 1, and FIG. 4 shows a cross-sectional structure of the adherend member 10 in FIG.

  As shown in FIGS. 3 and 4, the adherend member 10 is a rectangle in which a first sheet body 12 and a second sheet body 13 are laminated on a film sheet 11 made of resin (for example, made of polyethylene) and bonded to each other. It is said. The film sheet 11 is a sheet-like member formed of a film material having lower air permeability than the first sheet body 12 and the second sheet body 13. The first sheet body 12 is a sheet-like member containing a predetermined volatile component or the like, and is sandwiched between the film sheet 11 and the second sheet body 13. Moreover, as the 1st sheet | seat body 12, the structure using a nonwoven fabric, the structure using a gel-like sheet | seat, etc. may be employ | adopted. The second sheet body 13 is configured using the same non-woven fabric as the first sheet body 12. The second sheet body 13 prevents the first sheet body 12 containing a volatile component or the like from coming into direct contact with the wearer. The film sheet 11, the first sheet body 12, and the second sheet body 13 referred to here constitute “a plurality of sheet bodies having different air permeability” in the present invention, and in particular, the film sheet 11 referred to herein is the present invention. Corresponds to the “lowest breathable sheet”.

  Regarding the dimension of the adherend member 10, a belt-like body having a longitudinal length d1 of 10 to 40 mm and a lateral length d2 of 100 to 150 mm can be obtained. Although details will be described later, in order to ensure the desired air permeability of the mask main body 2, the adherent member 10 has an area on the wearing surface 2d side that is a predetermined area ratio to the entire area of the wearing surface 2d. It is preferable that it is comprised. The shape of the adherend member 10 can be appropriately changed to a shape other than a rectangle, for example, a shape such as a square, a circle, an ellipse, and a polygon, as long as the shape satisfies the predetermined area ratio.

  Further, the adherend member 10 has a folding line L extending in the vertical direction at a central position in the left-right direction. The fold line L has a function that enables the right side piece and the left side piece of the adherent member 10 to be folded (double fold), thereby releasing the folded state of the adherend member 10 and its folding. At least the expanded state can be formed.

  When the mask is stored or when the mask is not used, the right side piece and the left side piece of the adherend member 10 are overlapped with each other according to the fold line L and folded together with the mask body 2 as in the case of folding in FIG. Is possible. On the other hand, when the adherent member 10 is attached to the mask main body 2, the adherent member 10 is expanded to the left and right with the fold line L as a fulcrum, as in the case of attachment in FIG. In this case, the adherent member 10 has a convex shape with the fold line L as a protruding tip, and this convex shape engages with the concave portion 4 of the wearing surface 2d, so that the adherent member 10 is positioned on the mask main body 2. It is considered effective. In addition, this convex engaging action enables the configuration in which an adhesive body 10a described later is installed only on the left and right ends of the adherend member 10. The “engagement portion” in the present invention is configured by the configuration in which the convex shape formed at the center position of the adherend member 10 is engaged with the concave portion 4 of the wearing surface 2d.

  Furthermore, as shown in FIG. 5, it is preferable to employ a configuration in which the right and left pieces of the adherend member 10 are joined to each other in the vicinity of the fold line L. FIG. 5 shows a perspective view of the adherend member 10 in a form different from the embodiment shown in FIG. As shown in FIG. 5, it is preferable that the adherend member 10 is provided with a joining portion 14 that joins the right and left pieces in a line along the fold line L. According to such a configuration, the portion provided with the joint portion 14 becomes hard and the portion becomes a protruding tip when the adherend member 10 is expanded to the left and right. It becomes easier to position.

  In addition, the adherend member 10 of the present embodiment is provided with an adhesive body 10 a at both ends in the left-right direction of the film sheet 11. The bonded body 10a has a function of directly bonding the adherent member 10 to the adherent region B on the wearing surface 2d side by an adhesive structure between the adherent member 10 and the mask main body 2. This adhesive body 10a corresponds to the “adhesive body” in the present invention. According to such a configuration, a problem that occurs in a configuration in which the mask main body portion has a double structure of a nonwoven fabric and the adherend member is sandwiched, specifically, the operation of inserting the adherend member between the nonwoven fabrics causes the adherend member to be a nonwoven fabric. This is effective for improving the adherence operability (attachability) of the adherent member without causing a problem that the operation is troublesome due to interference.

(First adhesive structure)
The first adhesive structure of the adhesive body 10a of the present embodiment is configured by using the adhesive body 10a as an adhesive tape or an adhesive tape. This adhesive tape or pressure-sensitive adhesive tape is configured as a tape having a known configuration, and a tape having a predetermined adhesive force with a nonwoven fabric can be used. For example, the adhesive force of the adhesive tape or the adhesive tape is preferably set so as to exceed the holding force of the adherend member 10 and less than the force to remove the adherend member 10. According to such a configuration, the adherent member 10 can be repeatedly used by an operation of attaching or removing the adherent member 10 to or from the adherence area B. The adhesive tape or pressure-sensitive adhesive tape can be provided on at least one of the adherend member 10 and the mask main body 2. Further, in the first bonding structure, the bonded body 10a is disposed at a position corresponding to both ends of the bonded member 10 in the bonded region B and shifted from each other in the vertical direction. Is preferred. According to such a configuration, it is possible to prevent the left and right sides of the mask main body 2 from being bonded to each other by the adhesive bodies 10a when the mask main body 2 is folded.

(Second adhesive structure)
The 2nd adhesion structure of adhesion object 10a of this embodiment is constituted by using adhesion object 10a as a hook-and-loop fastener. This hook-and-loop fastener is a hook-and-loop fastener having a known configuration, is configured as a detachable tape utilizing a pile structure, and is also referred to as a so-called “magic tape”. Specifically, in this hook-and-loop fastener, the shape of a small mushroom-type bulge (the hook type is a hook-type hook) that is the insertion portion is arranged on one surface, and the shape of the loop that is the insertion portion is It is arranged on the other surface. When these two surfaces are pasted together, the mushroom (or hook) is caught (entangled) in the loop, so that it sticks easily. When peeling off, the mushroom (or hook) comes off easily by pulling each other. It can be peeled off. That is, the adhesive force of the hook-and-loop fastener is set so as to exceed the holding force of the adherend member 10 and less than the force to remove the adherend member 10. Therefore, the adherend member 10 is configured to be detachable from the adherence region B by using the second adhesion structure.

  In the second adhesive structure, the adhesive body 10a is used as an insertion portion, and a structure corresponding to the insertion portion is provided on the wearing surface 2d of the mask main body 2 or the ear hooking portion 3, or the mask main body 2 or The structure etc. which use the fiber structure of the nonwoven fabric itself in the ear hook part 3 as a to-be-inserted part can be employ | adopted suitably. In particular, according to the configuration in which the fiber structure of the nonwoven fabric itself is used as the inserted portion, the inserted portion is not required separately, which is effective in simplifying the bonding structure. When the non-woven fabric of the ear hook portion 3 is configured as a non-woven fabric having higher elasticity than the mask main body portion 2 and having a coarse fiber structure, the non-woven fabric of the ear hook portion 3 is preferably used as the insertion portion of the hook-and-loop fastener.

  For the state in which the wearer wears the mask 1 having the above-described configuration, FIG. FIG. 6 shows a side view of the mask wearing state in which the wearer wears the mask 1 of the present embodiment. As shown in FIG. 6, a mask covering the mouth and nose of the wearer, in particular, a three-dimensional mask in which the mask main body 2 is formed into a three-dimensional shape by a sheet piece like the mask 1 of the present embodiment is a three-dimensional mask. By forming the mouth space 5 between the main body 2 and the wearer's mouth, there is a possibility of eliminating discomfort such as breathlessness, but the covering member 10 further containing a volatile component etc. By adhering to the part 2, it is possible to supply a volatile component or the like to the mouth space 5 and create an environment useful for the wearer in the mouth space 5.

  In this case, with respect to the deposition region B to which the deposition member 10 is deposited, the region excluding the front of the mouth, particularly the region above the mouth (for example, in FIG. It is preferable to adhere the adherend member 10 at a position indicated by a broken line. More preferably, in order to prevent obstruction of nasal breathing, the adherend member 10 is attached to a region above the nose tip (nose hole) (for example, a position indicated by a two-dot chain line in FIG. 6). it can. When the adherent member 10 is attached to a region above the nose tip (nose hole), the adherent member is caused to move upward from the wearer's nose tip to move volatile components diffused toward the wearer side. The volatile components and the like can be easily retained in the mouth space 5 between the mask main body formed below the nose tip and the wearer's mouth.

  In addition, if the area ratio of the area on the wearing surface 2d side of the adherend member 10 to the area of the wearing surface 2d of the mask main body 2 is too large, the air permeability of the mask main body 2 is reduced, and the wearer feels stuffy. There is concern about becoming. Therefore, the present inventors have examined a preferred area ratio for securing a desired air permeability in the mask main body 2. Specifically, it is difficult for the wearer to feel stuffy when the pressure inside the mask is within a prescribed range, and when the pressure inside the mask is outside the prescribed range, the wearer is likely to feel stuffy. The pressure in the mask is measured when the area of the deposition member, that is, the area ratio of the deposition member to the mask body is changed. Thereby, it becomes possible to set a preferable area ratio of the adherend member to the mask main body. For this discussion, reference is made to FIGS.

  FIGS. 7 and 8 schematically show how the pressure in the mask is measured when the mask is worn. In this measurement, first, a measuring instrument is set as shown in FIG. As this measuring device, a pressure tube inserted in the mask (for example, SPLS2-1000 φ2 × φ1 manufactured by MISUMI Corporation), a pressure tube (for example, TH0425BU-20 manufactured by SMC), pressure detection A converter (as an example, a 5580D type manufactured by Ivision Co., Ltd.), a data logger (Lab-Pico-Q2 type manufactured by Rohm Riken), or a PC (personal computer) can be used. Next, in a state where the wearer's face does not move, a hole having the same width as that of the pressure tube for passing the pressure tube through the mask is made, and the tip of the pressure tube is 1 cm below the wearer's nose. The pressure detection tube is fixed so as to be perpendicular to (see FIG. 8). At this time, be careful not to hit the pressure gauge with anything else. In this case, it is preferable that the deposition member is deposited on a region of the mask main body above the mouth. Then, after setting the data collection method on the PC, the start button of the data logger is pushed to start measurement. As a result, data relating to the pressure in the mask is taken into C. When a prescribed measurement time (for example, 100 seconds) is reached after the start of measurement, the measurement is terminated. The average value of the peak of pressure when the wearer exhales and the average value of the peak of pressure when the wearer inhales are measured from the data taken into the PC.

Regarding the results of the above measurement, FIG. 9 shows a measurement result 1 of the pressure in the mask when the mask is worn (the air permeability of the mask body: 140 cc / cm 2 · sec). FIG. 10 shows measurement result 2 of the pressure in the mask when the mask is worn (the air permeability of the mask body: 200 cc / cm ² · sec). As shown in FIG. 9, when the air permeability is based on the measurement result when using a mask body portion of 140 cc / cm 2 · sec, Examples 1 to 3 are preferable to ensure the desired air permeability. It can be evaluated that it is preferable to set the area ratio of the adherend to the main body to 10 to 60%. Moreover, as shown in FIG. 10, when based on the measurement result when using the mask main-body part whose air permeability is 200 cc / cm <2> sec, Examples 1-4 are preferable in order to ensure desired air permeability, Therefore, it can be evaluated that it is preferable to set the area ratio of the adherend to the mask main body to 10 to 75%. In addition, in this evaluation, it is statistically difficult for the wearer to feel stuffy when the pressure in the mask is within a predetermined range (± 0.6 mmaq), and the pressure in the mask is within the predetermined range (± 0.6 mmaq). It is said that the wearer feels stuffy when he / she goes off. In addition, the lower limit of the area ratio is appropriately set according to the properties of the volatile agent and the like as long as the volatile agent contained in the adherent member can provide the wearer with the minimum effect.
