DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a face mask provided with a wearing band for wearing a mask body on a face.
Further, the present invention relates to a method for manufacturing such a facial mask with a wearing band.

[0002]

2. Description of the Related Art A small and lightweight face mask, such as a nostril mask having a respiratory air filtering action for dust prevention and antibacterial action, covering a required portion of the face, is provided with a wearing band for wearing the mask body on the face. Things are known. The dressing band is generally made of a flat or round string material having flexibility or elasticity so as not to impair the portability and disposability of the face mask, and an ear hanging type that hangs on both ears of the user, A neck-hung type surrounding the user's head is adopted under an appropriate configuration in accordance with various regulations in the field of use of the mask and trends of the user.

For example, in the field of industrial dust masks, lightweight and simple dust masks having a mask body formed by three-dimensionally forming a filter material such as a nonwoven fabric into a cup shape have been widely used in recent years. In this type of dust mask, in order to maintain the desired dustproof performance, regardless of whether the wearing band is an ear hanging type or a neck hanging type, the wearing band itself and the mounting position of the wearing band to the mask main body are used. It is stipulated by national certification standards that both have a tensile strength (ie, mounting strength) of 10 N (1.02 kg) or more.

[0004] In addition, in industrial dust masks, in order to make the mask main body as close as possible to the user's face, a wearing band made of an elastically stretchable string material such as a rubber string is suitably used. . However, depending on the head size of the user,
At the time of wearing the mask, the elastic fastening force of the wearing band is too small to lower the adhesion, or the ear or the head may feel pain due to the excessive elastic fastening force. Therefore, it is desired that the length of the wearing belt can be freely adjusted according to the size of the head of the user. Not only industrial dust masks, but also medical masks and general cold prevention masks are required to have such a wearable belt whose length can be adjusted in order to improve face adhesion.

Japanese Patent Application Laid-Open No. 7-185027 discloses a medical or industrial face mask capable of adjusting the length of a wearing band. In this facial mask, the two-dimensionally spaced mounting edges on both sides of the three-dimensionally shaped mask body are separated from each other.
An elastic dressing band is fixedly attached at both ends of the portion by sewing or the like to form a pair of ear hanging type dressing bands. A tubular stopper made of a heat-shrinkable resin is slidably attached to each of the wearing bands so as to bundle the rings of the wearing bands fixed to the mask body at both ends. By moving the stopper to a desired position, the size of the ring of each dressing belt is adjusted according to the size of the user's head.

[0006] Japanese Utility Model Laid-Open No. 2-10864 discloses a simple dust mask provided with a wearing band mounting member that can comply with the above-mentioned national certification standard. In this dustproof mask, a wearing band is fixedly attached to both sides of the three-dimensionally formed mask body by attaching members at both ends thereof, and a neck-hanging wearing band surrounding the head is formed. The mounting member is a resin molded product integrally having a base buried in the mounting edge of the mask body and thermally welded, and a locking portion protruding from the base. The wearing band is meanderingly passed through two slits provided in the locking portion of the mounting member, and exhibits a desired tensile strength (that is, mounting strength) due to mutual friction between the wearing band and the peripheral edge of the slit. ing. According to such a configuration, the length of the wearing band can be adjusted by shifting the position of the wearing band passing through the slit. This type of wearing band mounting member that secures the mounting strength by mutual friction between the wearing band and the peripheral edge of the slit is also disclosed in, for example, Japanese Utility Model Laid-Open No. 57-126258.

[0007]

In a conventional face mask having a tubular stopper made of a heat-shrinkable resin as described above,
If the amount of contraction of the stopper is insufficient, it becomes difficult to maintain the ring of the wearing belt at a desired size, and the stopper is displaced while wearing the mask, resulting in reduced face adhesion, and the stopper being dropped or lost. And other problems.
In addition, since the tubular stopper must be manufactured in a separate process from the dressing band and attached to the dressing band, and then subjected to heat shrinkage, the mask manufacturing process becomes complicated, and in synergy with the increase in the number of parts, Problems such as a decrease in yield and an increase in mask manufacturing cost arise. In addition, the tubular stopper touches the skin around the user's ear, giving the user a feeling of discomfort and discomfort while wearing the mask.

In the conventional face mask provided with the above-mentioned wearing band attaching member, the attaching member having the slit having the shape and arrangement capable of exerting the desired friction is manufactured in a process different from the mask main body. In addition, since the mask must be fixed to the mask body by welding or the like, the manufacturing process of the mask becomes complicated, and the increase in the number of parts is accompanied by a decrease in yield and an increase in mask manufacturing cost. Further, since the mounting strength is ensured by mutual friction between the wearing band and the peripheral edge of the slit, it is not easy to adjust the length of the wearing band to the slit.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a face mask capable of adjusting the length of the wearing band according to the size of the user's head, while ensuring the desired mounting strength of the wearing band on the mask body. It is an object of the present invention to provide a face mask with a wearing band that can easily and reliably adjust the wearability and does not give a user a feeling of discomfort or discomfort while wearing the mask.

Another object of the present invention is to provide a method of manufacturing the above-described facial mask with a garment band.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on preferred embodiments with reference to the accompanying drawings. In the drawings, the same or similar components are denoted by the same reference numerals. FIG. 1 shows a facial mask 10 with a garment according to a first embodiment of the present invention. The face mask 10 includes a cup-shaped mask body 12 and two wearing bands 14 attached to both side ends of the mask body 12. The mask body 12 has a cup shape bulging to a size large enough to cover the user's nares and mouths with a margin, and preferably has a contour along its outer periphery that can be in close contact with the user's face. The edge region 12a having a predetermined width is formed. In addition, the mask main body 12 does not necessarily need to include such an edge region 12a.

The mask body 12 is formed of a filtering material such as a nonwoven fabric three-dimensionally and integrally, and has a respiratory air filtering function for dust prevention and antibacterial. Such a face mask 1
0 is particularly suitably used as a lightweight and simple industrial dust mask or medical mask. However, it can also be used as a general cold prevention mask. A flexible frame piece 16 made of aluminum or the like is provided on the outer surface of the mask body 12 at a portion covering the nose of the user when wearing the mask.
Is attached. User wears frame piece 1 when wearing mask.
By deforming 6 according to the shape of the nose, the adhesion of the mask body 12 around the nose can be further improved.

At the edge region 12a of the mask main body 12, mounting edge portions 18 for mounting the wearing band 14 are provided at both side end portions separated from each other near the user's both ears when the mask is worn.
Are respectively formed. Each of the two garments 14 is attached to each of the mounting edges 18 near the longitudinal ends 14a.
At two upper and lower locations separated from each other. Thus, each of the wearing bands 14 is configured as an ear hanging-type wearing band. Each wearing belt 14 is provided on the face of the user with the mask body 1.
In order to make the two edge regions 12a as close as possible, it is preferable that the edge regions 12a are formed of a resiliently stretchable string material such as a rubber string. When the mask main body 12 does not include the edge region 12a, the wearing band 14 can be attached to a desired region (that is, a peripheral region) near the periphery of the cup-shaped mask main body 12.

Each of the wearing bands 14 is fixedly attached to the mounting edge 18 by a pair of fixing staples 20 fixed to two upper and lower portions of the mounting edge 18 of the mask body 12 near both ends 14a in the longitudinal direction. Can be Therefore, each fixing staple 20 constitutes the fixing means of the present invention. Further, each wearing band 14 is slidable on the mounting edge 18 by a sandwiching staple 22 fixed to the mounting edge 18 of the mask main body 12 on the inner side in the length direction of the wearing band 14 with respect to the both fixed staples 20. Mounted. Therefore, the sandwiching staple 22 constitutes the sandwiching means of the present invention.

Fixed staple 20 and pinched staple 2
2 is a U-shaped nail made of a metal material such as iron or aluminum, as shown in FIGS. 2 (a) and 2 (b).
The two legs 20a, 22a are attached to the mounting edge 18 of the mask body 12.
Is fixed to the mounting edge portion 18 by being bent. In this state, the wearing band 14 is held under pressure between the heads 20b and 22b of the fixed staple 20 and the sandwiching staple 22 and the mounting edge portion 18, so that the wearing band 1
4 is attached to the mounting edge 18.

The fixed staples 20 and the sandwich staples 22 at each mounting edge 18 are arranged substantially parallel to the outer edge 18a of the mounting edge 18 closest to both ears of the user when wearing the mask. Further, the sandwiching staples 22 are arranged in parallel with and adjacent to the fixed staples 20 installed at the lower mounting portions of the mounting edge portions 18 and at a position farther from the outer edge 18a of the mounting edge portion 18 than the fixed staples 20, that is, in a cup shape. The swelling mask body 12 is installed at a position biased toward the center of the swelling mask body 12.

Under such a staple arrangement, each of the wearing belts 14 has its longitudinal ends 14a separated from the two fixed staples 20 at each of the mounting edges 18 by the outer edge 1 of the mounting edge 18.
Each of the fixing staples 20 is attached to each mounting edge 18 such that the lengthwise inner portion of the wearing band 14 extends from each of the fixing staples 20 toward the center of the mask body 12. Further, between the fixed staple 20 and the sandwiching staple 22 at the lower mounting point of each mounting edge 18, the desired adjustment length portion 14b of the wearing band 14 can be loosened and arranged in a loop. (FIGS. 1 and 3
reference).

As described above, in the face mask 10, the wearing belt 1
The wearing band 14 is fixedly attached to the mask body 12 by sandwiching the fixing member 4 between the fixed staple 20 and the attachment edge 18 under pressure. The fixed mounting strength obtained thereby is not only strong enough to stably maintain the mounting state with respect to the tensile load applied to the wearing band 14 in the longitudinal direction when wearing a normal mask, but also to the wearing band 14. Even if an excessively large tensile load is intentionally or inadvertently applied, it is desirable that the mounting state can be maintained to the extent that the mask main body 12 and the wearing band 14 themselves are not damaged. That is, the term “mounting strength” in the present embodiment is:
The strength of the fixing action of the fixed staple 20 or the narrow staple 22 to the mask main body 12, the strength of the wearing band holding action by the frictional force between the mask main body 12 and each of the staples 20, 22, and the wearing band 14 itself Should be understood to include the tensile strength of

For example, when the face mask 10 is used as an industrial dust mask, the face mask 10 specified by the national certification standard is used.
It is necessary that the fixed staple 20 can exhibit an attachment strength corresponding to a tensile strength of 0N (1.02 kg) or more. However, the fixed attachment effect of the fixed staple 20 does not need to be a strong mechanical fixation comparable to sewing or welding, and the garment belt 1 is not affected by an excessive tensile load exceeding a predetermined amount.
4 may be allowed. Thereby,
It is possible to prevent the mounting edge portion 18 and the wearing band 14 themselves from being damaged when an excessive tensile load is applied to the wearing band 14.
Further, when the loop-shaped adjustment length portion 14b (FIG. 3) of the wearing band 14 becomes excessive, the one end 14a is intentionally pulled by an excessive tensile force to move the one end 14a from the fixed staple 20 to the outside of the mounting edge portion 18. It is also possible to cut out the excess length that has been pulled out. However, in the present invention, other fixing means having a fixed attaching action, such as sewing and welding,
The fixing staple 20 may be used instead of the fixing staple 20.

On the other hand, the sandwiching staple 22 is a member for allowing the length of the wearing band 14 to be adjusted as described later, so that the user intentionally pulls the wearing band 14 in the length direction. Accordingly, it is only necessary that the wearing belt 14 can exhibit an attachment strength that can relatively easily slide between the sandwiching staple 22 and the attachment edge 18. However, for a tensile load applied to the dressing band 14 in the length direction during normal mask wearing, it is possible to exhibit strength enough to stably maintain the attached state. It is important to prevent length fluctuation.

Fixed staple 20 and pinched staple 22
For example, the staples 20 and 22 and the mounting edge 18 are appropriately adjusted by appropriately adjusting the driving load, the driving acceleration, the thickness of the staple material, and the like at the time of staple driving.
This can be achieved by differentiating the frictional force generated between the garment and the garment 14. For example, in the illustrated embodiment, the fixing staple 20 is made of a material that is particularly thicker in the width direction than the sandwiching staple 22, and the fixing staple 20 is driven with a larger force than the sandwiching staple 22 to differentiate the mounting strength. (See FIGS. 2A and 2B).

Further, in the illustrated embodiment, by adopting the characteristic arrangement of the staples 20 and 22 described above,
During the wearing of the mask, each of the wearing bands 14 is approximately 18 by the fixed staples 20 at the mounting positions above the mounting edges 18 and by the sandwiching staples 22 at the lower mounting positions.
The state is turned back at 0 °. Therefore, during the actual wearing of the mask, a part of the tensile load applied to the dressing band 14 is received by the staples 20 and 22 that fold the dressing band 14, and thus is measured when the dressing band 14 is pulled in the length direction without being turned back. Thus, the staples 20, 22 can exhibit a larger mounting strength than the mounting strength.
In order to further enhance the effect of increasing the mounting strength due to such folding, the illustrated embodiment particularly uses the wearing band 14 made of a flat rubber cord.

To adjust the length of the wearing band 14 on the face mask 10, the wearing band 14 is appropriately slid between the mounting edge 18 and the sandwiching staple 22, so that the fixed staple 20 and the sandwiching staple at the lower attachment point are adjusted. The adjustment length portion 14b in the form of a loop of the dressing belt 14 located between the control belt 22 and the belt 22 (FIGS. 1 and 3).
This is done by increasing or decreasing the length of This length adjustment work is usually performed when the mask is not worn.
After wearing the face mask 10 in a state where 4 is pre-adjusted to the head size of the user, simply pulling the loop-shaped adjustment length portion 14b of the desired dressing band 14 to increase its length, Wearing bandage 14 while wearing face mask 10
Can be easily and optimally adjusted.

This is equivalent to the case where the sandwiching staple 22 pulls the inner portion in the longitudinal direction of the garment band 14 without turning it back toward the center of the mask against the tensile load in the length adjusting direction. This is because only the mounting strength is exhibited.
On the other hand, the fixed staple 20 has an attachment strength enough to maintain the attached state against such a tensile load in the length adjustment direction, so that the distal end 1 of the cuff 14 is adjusted during the length adjustment.
4a does not fall off the fixed staple 20.
Furthermore, while the face mask 10 is worn, the sandwiching staples 22 exhibit an enhanced attachment strength when the lengthwise inside portion of the garment band 14 is folded back toward the outer edge 18a of the attachment edge 18 and pulled. Therefore, it is possible to reliably prevent the optimally adjusted length of the garment band 14 from fluctuating during wearing.

As an example, the preferable mounting strength of the wearing band 14 when the face mask 10 is applied to an industrial dust mask is shown by specific numerical values below. The mounting strength shown below was measured using the lower chuck of the tensile tester.
2 is gripped, the upper chuck is used to grip a portion 30 mm from the position where the staples 20 and 22 are attached to the dressing band 14 made of a flat rubber cord, and the load at the time of breakage when pulled at a speed of 200 mm / min. Is measured.

First, the fixed staple 20 is
With the staples 20 attached as described above.
The inner portion of the wearing belt 14 in the longitudinal direction is
In the direction of the center, that is, when pulled without folding (arrow α in FIG. 4A), the mounting strength of 0.5 kg to 3.5 kg can be exhibited, and the inner side portion of the wearing band 14 is attached to the mounting edge 18.
In the direction of the outer edge 18a, that is, when folded and pulled (arrow β in FIG. 4B), it is preferable that the mounting strength of 1.1 kg to 5.0 kg can be exhibited.

On the other hand, the sandwiching staple 22 is
In the same manner as described above, when the inner portion in the longitudinal direction of the wearing band 14 is pulled toward the center of the mask body 12, that is, when it is pulled without being folded, 0.05 kg to 0.5 kg
It is preferable to be able to exhibit a mounting strength of 0.1 kg to 1.1 kg when the same inner portion of the dressing belt 14 is pulled toward the outer edge 18 a of the mounting edge 18, that is, when it is folded and pulled. .

From the above numerical range, the fixed staple 2
By appropriately selecting and combining the mounting strengths of the staples 22 and the staples 22, it is possible to easily and surely adjust the length of the garment band while securing the mounting strength of the garment band specified by the national certification standard. In addition, there is provided a face mask 10 that can effectively prevent the adjusted length of the wearing band from fluctuating during wearing. Furthermore, in the face mask 10, since the loop-shaped adjustment length portion 14b of the dressing band 14 is formed at a position where it does not touch the user's face, the user does not feel discomfort or discomfort while wearing the mask. There are advantages. Moreover,
Since simple and inexpensive staples are employed as the attaching means of the wearing band 14, manufacturing costs can be reduced.

The sandwiching staples 22 can be installed at the upper mounting points instead of the lower mounting points of each mounting edge 18 as in the illustrated embodiment, or are installed at both the upper and lower mounting points. You can also. The staples 20 and 22 may be arranged so as to intersect with the outer edge 18a instead of being substantially parallel to the outer edge 18a of the mounting edge 18 as shown. However, in this case, in order to exhibit the effect of increasing the mounting strength by the folding described above, it is important that the sandwiching staple 22 is arranged at least somewhat farther from the outer edge 18a than the fixed staple 20, that is, it is biased toward the center of the mask. is there.

In the manufacturing process of the face mask 10, the fixing staple 20 is driven into the mounting edge 18, and the wearing band 14 is fixedly mounted on the mounting edge 18 near both ends 14 a in the longitudinal direction. And slidably mounting the garment band 14 on the mounting edge 18 in the lengthwise direction with respect to the two fixed staples 20 at the same time for all the staples 20 and 22. This is particularly effective from the viewpoint of simplifying the mask manufacturing process. Such a simultaneous driving operation can be performed by a known driving machine (stapler) having a plurality of driving heads. In such a driving machine, the fixed staple 20 and the sandwich staple 22 can be driven simultaneously with different loads and accelerations.

As described above, the face mask 10 is provided with the two ear hanging-type wearing bands 14, but is provided with the neck hanging type wearing band by using the engaging member 24 as shown in FIG. 5, for example. It can also be used as a face mask. The engaging member 24 is, for example, a substantially elliptical small piece stamped and formed from a plastic plate, and can be freely hung on the through hole 26 that can loosely hold one of the wearing bands 14 and the other wearing band 14. And a hook 28. further,
A slit 30 for inserting one of the wearing bands 14 into the through hole 26 is provided in communication with the through hole 26.

In this case, the user turns the two wearing bands 14 toward the back of the head, and hooks the hook 28 of the engaging member 24 attached to one of the wearing bands 14 on the other wearing band 14 so that the user's face can be seen. The mask 10 can be worn on the neck. In this case, the face mask 10 can be used in two ways, an ear hanging type and a neck hanging type, and the user can use the wearing band 14 according to his / her taste or the degree of fatigue of the head and ears. You can choose the law. In addition, as such an engaging member, various other types, such as a pair of fastener members attached to each of the two wearing bands 14, can be adopted.
