Description

mask

The present invention relates to a structure technology of a mask to be worn on a wearer's face.

Conventionally, for example, the following patent document discloses a mask having a fibrous substance composed of microporous hollow fibers containing menthol.

JP-A 63-209666

Here, in order to improve the collection property of the mask (for example, bacterial splash filtration efficiency BFE), it is necessary to reduce the air permeability of the outer nonwoven fabric sheet arranged outside the mask (increase the air resistance). On the other hand, if the air permeability of the outer nonwoven fabric sheet is lowered, the wearer feels breathlessness. For this reason, development of the outer nonwoven fabric sheet which can make both the collection property and breathability of a mask compatible at a high level is advanced. In parallel with the development of the outer nonwoven fabric sheet, the present inventors also examined the inner nonwoven fabric sheet disposed on the wearer side. As a result, the breathability of the inner nonwoven fabric sheet was increased more than the breathability of the outer nonwoven fabric sheet. The present inventors have found that the fragrance generated from the fragrance can easily reach the wearer's nostril mucosa, making it difficult to feel breathlessness.
Therefore, an object of the present invention is to provide a novel technique capable of achieving both the trapping property and the air permeability of the mask at a high level.

The present invention includes a mask body that covers at least the mouth and nose of the wearer. In general, a mounting member for mounting the mask main body is provided. As the mounting member, for example, an ear hook portion that is hooked on the wearer's ear, a headband portion that is hung around the wearer's head, or the like is used. The mask body has an inner nonwoven fabric sheet, an outer nonwoven fabric sheet, and a fragrance-containing nonwoven fabric sheet provided between the inner nonwoven fabric sheet and the outer nonwoven fabric sheet, and the inner nonwoven fabric sheet is arranged on the wearer side when the mask is worn. Are stacked as shown.
The perfume-containing non-woven sheet includes microcapsules containing a perfume. As the microcapsule, a capsule that can be easily broken by applying an external force such as tapping with a hand or peeling with a hand is used. Various fragrance | flavors can be used as a fragrance | flavor. For example, menthol, which is effective for rhinitis, sneezing due to allergies, nasal discharge, and nasal congestion, can be used.
And the air permeability of an inner side nonwoven fabric sheet is set so that it may be higher than the air permeability of an outer side nonwoven fabric sheet (air permeability resistance is small). In addition, the air permeability of the outer nonwoven fabric sheet is enhanced within a range where the trapping property of the mask does not deteriorate.
In the present invention, since the breathability of the inner nonwoven fabric sheet is set higher than the breathability of the outer nonwoven fabric sheet, the scent generated by the breakage of the microcapsules contained in the fragrance-containing nonwoven fabric sheet is in the nostril mucosa of the wearer. It becomes easier to reach and the wearer is less likely to feel stuffy.

In a different form of the present invention, the outer nonwoven fabric sheet has an average fiber diameter of 1 to 3 μm and a basis weight of 2 to 5 g / m ² and is configured as an electret nonwoven fabric sheet.
In this embodiment, it is possible to easily obtain a mask in which the mask collecting property and air permeability are compatible at a high level.

In another different form of the invention, the frictional resistance between the inner nonwoven sheet and the perfume-containing nonwoven sheet is less than the frictional resistance between the inner nonwoven sheet and the outer nonwoven sheet. The frictional resistance can be changed, for example, by selecting a material included in the inner nonwoven fabric sheet.
In this embodiment, when an external force is applied to the mask body by hand or the like, among the microcapsules contained in the fragrance-containing nonwoven fabric sheet, the microcapsules existing in the region facing the inner nonwoven fabric sheet are easily destroyed. .

In another different form of the present invention, the perfume-containing non-woven sheet is composed of a non-woven sheet and a microcapsule containing a perfume that is applied to a region of the non-woven sheet facing the inner non-woven sheet.
In this embodiment, since the microcapsules are arranged in the region facing the inner nonwoven fabric sheet, the scent generated from the fragrance easily reaches the wearer's nostril mucosa.
In addition, by combining the configuration of this embodiment and the configuration described above, the friction resistance between the inner nonwoven fabric sheet and the fragrance-containing nonwoven fabric sheet is smaller than the friction resistance between the inner nonwoven fabric sheet and the outer nonwoven fabric sheet, An advantageous effect occurs. That is, the microcapsule can be easily broken and the microcapsule can be arranged at a position where the microcapsule is easily broken.

In another different form of the present invention, the mask main body has an upper joining region and a lower joining region where the inner nonwoven fabric sheet, the fragrance-containing nonwoven fabric sheet and the outer nonwoven fabric sheet are joined. And in the upper side joining area | region and lower side joining area | region of a mask main-body part, the microcapsule is not contained in the fragrance | flavor containing nonwoven fabric.
With this form, when an upper side junction part and a lower side junction part are formed, it can prevent destroying the microcapsule containing a fragrance | flavor unintentionally.

In another different form of the present invention, the upper joining region is defined by the upper folded portion of the inner nonwoven fabric sheet folded on the upper side of the mask main body. Further, a lower bonding region is defined by a lower folded portion that is folded on the lower side of the mask main body.
In this embodiment, the upper joining region and the lower joining region can be easily defined, and the operation of embedding (applying) the fragrance-containing microcapsules in the fragrance-containing sheet can be easily performed.

In another different form of the invention, the mask body has a pressing area that is pressed by a nip roll during mask manufacture. And in the press area | region of a mask main-body part, the microcapsule is not contained in the fragrance | flavor containing nonwoven fabric.
In this embodiment, it is possible to prevent the microcapsules containing the fragrance from being unintentionally destroyed when pressed by the nip roll in the mask manufacturing process.

In the different form of this invention, the mask main-body part has the right side joining area | region where a right ear hooking part is joined by the right side joining part, and the left side joining area | region where a left side ear hooking part is joined by the left side joining part. And in the right side joining area | region and left side joining area | region of a mask main-body part, the microcapsule is not contained in the fragrance | flavor containing nonwoven fabric sheet.
In this embodiment, when the right side joint and the left side joint are formed, the microcapsules containing the fragrance can be prevented from being unintentionally destroyed.

In the different form of this invention, the mask main-body part has the some pleat extended in the left-right direction, and is comprised so that it may become three-dimensional at the time of mask wear.
In this embodiment, when the mask is worn, the center pleat in the vertical direction is arranged at a position away from the wearer's face. Thereby, it can prevent that the microcapsule containing a fragrance | flavor contacts a wearer's skin directly.

Note that the mask body 20, the left ear hook 70, and the right ear hook 80 can be formed integrally. For example, the mask 10 in which the mask main body 20, the left ear hook 70, and the right ear hook 80 are connected can be formed by folding one sheet piece.
The left ear hook portion 70 and the right ear hook portion 80 are formed of sheet pieces. As the sheet pieces forming the left ear hook portion 70 and the right ear hook portion 80, it is preferable to use a nonwoven fabric sheet having high stretchability. For example, a polypropylene (PP) / urethane nonwoven sheet having a fiber diameter of 21 μm, a basis weight of 73 to 77 g / m ² , and a ventilation resistance of 0.04822 kPa · s / m is used.

The left ear hook 70 has a base 71 and an edge (ear hook) 73 that extends from the base 71 and forms an opening 70a. The base 71 extends along the second direction Y.

Further, as shown in FIG. 3, the left ear hook 70 and the right ear hook 80 are folded back in the first direction X (left-right direction). That is, the edge 72 of the left ear hook 70 is folded back to the left along the first direction X. As a result, the portion of the left ear hook 70 that is closer to the edge 72 than the left joint 22 is folded back at the left joint 22. Further, the edge 82 of the right ear hook 80 is folded back along the first direction X to the right. As a result, the portion of the right ear hook 80 that is closer to the edge 82 than the right joint 23 is folded back at the right joint 23.

Then, the opening 70a of the left ear hook 70 is hung on the wearer's left ear, and the opening 80a of the right ear hook 80 is hung on the wearer's right ear.
At this time, the left joint portion 22 is covered with a part of the folded portion of the left ear hook portion 70. Further, the right joint portion 23 is covered with a part of the folded portion of the right ear hook portion 80. Thereby, at the time of mask wearing, it can prevent that the left side junction part 22 and the right side junction part 23 contact a wearer's skin directly.

In addition, when generating a fragrance, before wearing the mask 10, external force is applied by the mask main-body part 10 by hand etc., and the microcapsule contained in the fragrance | flavor containing nonwoven fabric sheet 40 mentioned later is destroyed.

Next, the configuration of the mask body 20 will be described with reference to FIG. 7 is a cross-sectional view taken along line VII-VII in FIG. In FIG. 7, for simplification of description, the ridges 20B to 20J of the mask body 20 are not shown.

The mask main body 20 is configured by laminating an inner nonwoven fabric sheet 30, a fragrance-containing nonwoven fabric sheet 40 containing a fragrance, an outer nonwoven fabric sheet (nonwoven fabric sheet for filter) 50 that acts as a filter, and a covering sheet 60. In addition, at the time of mask wearing, the inner side nonwoven fabric sheet 30 is arrange | positioned at a wearer side, and the coating sheet 60 is arrange | positioned at a wearer's opposite side (non-wearing side).

As the fragrance-containing nonwoven fabric sheet 40, a polypropylene (PP) spunbond nonwoven fabric sheet having a fiber diameter of 20.5 μm and a basis weight of 22.5 to 27.5 g / m ² is used, and includes a microcapsule containing a fragrance. Yes. As the microcapsule, a capsule that can be easily broken by applying an external force such as tapping with a hand or peeling with a hand is used. Various fragrance | flavors can be used as a fragrance | flavor. For example, menthol, which is effective for rhinitis, sneezing due to allergies, nasal discharge, and nasal congestion, can be used.

As the outer nonwoven fabric sheet 50, an electret (electret-treated) nonwoven fabric sheet containing polypropylene fibers is used. By this electretization, a predetermined amount of positive charge or negative charge is given to the polypropylene fiber surface, and dielectric polarization occurs. That is, desired electretization is possible for a nonwoven fabric sheet containing polypropylene fibers. As the outer nonwoven fabric sheet 50, a melt blown nonwoven fabric sheet (also referred to as a “melt blown nonwoven fabric sheet”) typically manufactured by a melt blow method (also referred to as “melt blown method”) can be used, and the average fiber diameter is further reduced. One having 1 to 3 μm, a weight per unit area of 2 to 5 g / m ² , and a ventilation resistance of 0.124 kPa · s / m can be used. In this case, the outer nonwoven fabric sheet 50 is obtained by electretizing a nonwoven fabric sheet containing at least polypropylene fibers, and the nonwoven fabric sheet may be composed only of polypropylene fibers, or may be further fibers in addition to polypropylene fibers. For example, you may comprise as what added the polyethylene fiber.

As the coated nonwoven fabric sheet 60, as with the outer nonwoven fabric sheet 50, an electret nonwoven fabric sheet containing polypropylene fibers is used. The electretization treatment of the coated nonwoven fabric sheet 60 can be appropriately performed together with the outer nonwoven fabric sheet 50 or independently of the outer nonwoven fabric sheet 50. The coated nonwoven fabric sheet 60 is typically a spunlace nonwoven fabric sheet produced by a spunlace method, an air-through nonwoven fabric sheet produced by an air-through method, a spunbond nonwoven fabric sheet produced by a spunbond method, or a needle punch method. The manufactured needle punched nonwoven fabric sheet can be used, and it is preferable to use one having an average fiber diameter of 15 to 30 μm and a basis weight of 18 to 50 g / m ² . The coated nonwoven fabric sheet 60 in this case is obtained by electretizing a nonwoven fabric sheet containing at least polypropylene fibers, and the nonwoven fabric sheet may be composed only of polypropylene fibers, or may be further fibers in addition to polypropylene fibers. For example, you may comprise as what added the polyethylene fiber.

As the inner nonwoven fabric sheet 30, unlike the outer nonwoven fabric sheet 50 and the coated nonwoven fabric sheet 60, a nonwoven fabric sheet that is not electretized is used. The inner woven fabric sheet 30 typically includes a polyethylene terephthalate fiber and a polyethylene fiber, and is a low-density point-bond nonwoven fabric sheet that has been point-bonded by a pressure roll (for example, a fiber diameter of 15.412 μm and a basis weight of 30 g). / M ² , a non-woven sheet having a ventilation resistance of 0.0533 kPa · s / m and a thickness or bulk of 0.20 mm or more. The inner nonwoven fabric sheet 30 having such a structure that directly touches the wearer's face (skin) is suitably used as a nonwoven fabric sheet having a good touch. In addition, as needed, as the inner side nonwoven fabric sheet 30, the nonwoven fabric sheet made from the electret polypropylene can also be used.

The inventors of the present invention performed a quantitative performance evaluation for confirming the air permeability and the trapping property of the mask body 20 of the present embodiment. In this evaluation, the air permeability [cc / cm ² / sec] related to the air permeability evaluation and the collection efficiency [%] related to the collection performance evaluation were measured. Regarding the measurement of air permeability, the amount of air [cc / cm ² / sec] passing through each evaluation piece was measured using a known Fragil type tester under a predetermined condition. In addition, regarding the measurement of collection efficiency, bacterial droplet filtration efficiency BFE (bacterial) is based on the test method specified in ASTM (American Society of Testing and Materials) F2101.
filtration efficiency) [%] was measured.

From the evaluation results, regarding the outer nonwoven fabric sheet 50, the average fiber diameter is 1 to 3 μm smaller than that of the coated nonwoven fabric sheet 60, and the basis weight thereof is 2 to 5 g / m ² smaller than that of the coated nonwoven fabric sheet 60. The mask air permeability can be increased to a level at which the air permeability becomes 70 [cc / cm ² / sec], and the mask collecting property can be increased to a level at which the reference value of the collection efficiency is 90%. Was confirmed.
The coated nonwoven fabric sheet 60 has an average fiber diameter of 15 to 30 μm, which is larger than that of the outer nonwoven fabric sheet 50, and a basis weight of 18 to 50 g / m ² which is larger than that of the outer nonwoven fabric sheet 50. It was confirmed that the mask air permeability can be increased to a level of [cc / cm ² / sec] and the mask collecting property can be increased to a level at which the reference value of the collection efficiency is 90 [%]. .

As described above, the mask 10 according to the present embodiment uses an electret nonwoven fabric sheet having an average fiber diameter of 1 to 3 μm and a basis weight of 2 to 5 g / m ² as the outer nonwoven fabric sheet 50, and has an average fiber diameter. By using an electretized non-woven sheet having a size of 15 to 30 μm and a basis weight of 18 to 50 g / m ² as the coated non-woven sheet 60, a mask structure that achieves a high level of both mask breathability and mask collection is realized. Can do. Further, if necessary, an electret nonwoven fabric sheet having an average fiber diameter of 1 to 3 μm and a basis weight of 2 to 5 g / m ² is used as the outer nonwoven fabric sheet 50. In addition, an electretized nonwoven fabric sheet exceeding the above numerical range (average fiber diameter: 1 to 3 μm, basis weight: 2 to 5 g / m ² ) can be used as the coated nonwoven fabric sheet 60. In this case, while suppressing the average fiber diameter and basis weight of the outer nonwoven fabric sheet 50 to be electreted, the mask collecting property can be improved, while the average fiber diameter and basis weight of the coated nonwoven fabric sheet 60 to be electret are relative to each other. Therefore, the air permeability of the mask can be ensured.

Moreover, in this Embodiment, since the nonwoven fabric sheet of the outer side nonwoven fabric sheet 50 and the covering nonwoven fabric sheet 60 is comprised using the polypropylene fiber among polyolefin-type fibers, it is possible to perform electretization especially easily. In addition, an inexpensive mask with excellent cost is provided. If necessary, the outer nonwoven fabric sheet 50 and the coated nonwoven fabric sheet 60 may be made of polyolefin fibers other than polypropylene fibers, such as polyethylene fibers and poly 1-butene fibers.

In addition, in said embodiment, although the mask main-body part 20 described about the mask provided with the inner side nonwoven fabric sheet 30, the fragrance | flavor containing nonwoven fabric sheet 40, the outer side nonwoven fabric sheet 50, and the covering nonwoven fabric sheet 60, this invention is a mask main-body part. However, what is necessary is just to provide the inner side nonwoven fabric sheet 30, the fragrance | flavor containing nonwoven fabric sheet 40, and the outer side nonwoven fabric sheet 50 at least.

Here, in this Embodiment, the frictional resistance between the inner side nonwoven fabric sheet 30 and the fragrance | flavor containing nonwoven fabric sheet 40 is set smaller than the frictional resistance between the fragrance | flavor containing nonwoven fabric sheet 40 and the outer side nonwoven fabric sheet 50. FIG. Thereby, when an external force is applied to the mask body 20 by hand or the like, among the microcapsules contained in the fragrance-containing nonwoven fabric sheet 40, the microcapsules arranged in the region facing the inner nonwoven fabric sheet 30 It becomes easy to be destroyed.
In this Embodiment, the friction between the inner side nonwoven fabric sheet 30 and the fragrance | flavor containing nonwoven fabric sheet 40 is made to contain the silk protein for improving the touch in the inner side nonwoven fabric sheet 30 using the adhesive agent containing silicon. The resistance is lowered.
In addition, as a method of reducing the frictional resistance between the inner side nonwoven fabric sheet 30 and the fragrance | flavor containing nonwoven fabric sheet 40, methods other than this can be used.

Moreover, in this Embodiment, the microcapsule containing a fragrance | flavor is apply | coated to the area | region which faces the inner side nonwoven fabric sheet 30 of the nonwoven fabric sheet which comprises the fragrance | flavor containing nonwoven fabric sheet 40. FIG.
When a microcapsule is disposed in a region close to the wearer's face, the fragrance is generated when the microcapsule is destroyed, compared to a case where the microcapsule is disposed in a region far from the wearer's face. The scent tends to reach the wearer's nasal mucosa.
Thereby, this Embodiment is equipped with the structure which facilitates destruction of the microcapsule arrange | positioned to the area | region where a fragrance is easy to transmit, and the microcapsule arrange | positioned to the area | region where a fragrance is easy to transmit.
