Abstract

PROBLEM TO BE SOLVED: To inexpensively manufacture a shape retaining tool for retaining a swelling of a mask body, and reduce an obstacle for making it disposable, thereby making it hygienically effective, and thin and compact. SOLUTION: Both ends of a bendable supporting frame member can be fixed to the inside of a mask body by a fixing means. Therefore, the supporting frame member bent before the face of a user supports the mask body from the inside and retains a swelling. The shape retaining tool does not require an expensive solid domical shape retaining tool and can be realized by using plane members. Therefore, it can be made inexpensive. Making it disposable will not pose any economic inconvenience and proves hygienically effective. The tool can be flattened in any cases other than when a user uses the tool. Therefor, it can be easily made thin and compact.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shape-retaining means for enhancing the breathability of a mask, and more particularly to a shape-retaining plate which is inexpensive and easy to be made compact.

[0002]

2. Description of the Related Art Conventionally, generally, a mask having a substantially rectangular mask body with wearing straps is widely used to capture bacteria, viruses, animal and plant cells, toxic gas, malodorous components, dust, pollen, etc. in the air. It is used. And recently, there is also a thin mask made of a thin and flexible mask material in which a filter material with excellent breathability such as a mechanical filter or an electrostatic filter is sandwiched between outer skins such as gauze or non-woven fabric, and the above filter material is not suitable for washing. Disposable after several uses,
It is widely used due to its excellent hygiene.
It is also thin and compact, which is convenient for storage and transportation.

There is also a thin mask having a three-dimensional bulge. That is, the peripheral portion of the mask body plays a role of a frame, the peripheral portion is mounted so as to fit the user's face, and the three-dimensional bulge is provided with a margin inside the peripheral portion. It can be formed. As a result, the area of the breathable portion of the mask body is increased, the breathability is enhanced, and breathing is facilitated. As a specific means for giving a margin to the mask body, it is common to form several lateral pleats to widen the pleats. The lateral direction of the face of the user is the lateral direction of the mask. As a problem of the mask, since the mask material is thin and flexible, the inflated part of the mask body is sucked into the mouth by the user's inhalation, and eventually only the part that hits the opening of the mouth inhales. There was a drawback that the ventilation area became small and it was stuffy.

In order to reduce the above-mentioned breathlessness, JP-A-9-
There is an object such as 276424 in which a mask is provided with a shape retainer on a dome to secure a space in front of the mouth of the user to eliminate stuffy breath.

[0005]

From the above, it can be considered to dispose the three-dimensional dome-shaped mold retainer in the inflated space of the mask in order to reduce the breathing difficulty. Here, the two-dimensional and one-dimensional shapes such as a flat plate shape and a rod shape are combined and described as a planar shape for convenience.
Since these planar members can be manufactured by a relatively simple operation such as punching a resin plate or simply cutting a rod, the manufacturing cost can be easily suppressed. However, in comparison, the three-dimensional three-dimensional member such as the above-mentioned three-dimensional dome-shaped shape retainer is required to perform injection molding of resin with a mold or suction molding by heating a resin plate. In many cases, a die is required, and a means for keeping the resin at a predetermined temperature is required, which makes the work complicated and requires an expensive machine. Therefore, it is difficult to reduce the manufacturing cost of the three-dimensional dome-shaped shape retainer. Therefore, it was expensive and difficult to dispose of. Therefore, although the thin mask is disposable, it is difficult to dispose the three-dimensional dome-shaped shape retainer, so it is actually possible to use the three-dimensional dome-shaped shape retainer attached to the thin mask. It was hard to do. Therefore, there has been a demand for a shape-retaining means that is cheaper, and therefore can be practically made disposable, and that is suitable for use in the above-mentioned thin mask and that can be maintained hygienically. Further, while the mask is easy to be thin and compact, the three-dimensional dome-shaped shape retainer is difficult to be compact due to its shape characteristics, so that it can be made thin and compact, which is convenient for storage and transportation. A shape-retaining measure was required.

[0006]

In order to solve the above problems, the present invention has the following technical means. That is, it is arranged in a mask in which wearing straps are arranged on both sides of a substantially rectangular mask body, and moreover, the mask body is designed to have a bulge so as to form a space in front of the mouth of the user. In the shape-retaining means for securing, the mask body has both end portions fixed to both side edge portions inside the mask main body, and a bridging portion which elastically curves between the both end portions. A mask retainer comprising: a support frame for receiving the main body from the inside; and fixing means for fixing at least both end portions of the support frame to the inside of the mask main body. Further, a retainer used for a mask having lateral pleats on the mask body, wherein the support frame is arranged in the pleats of the pleats of the mask body that are valleys inside the mask. You may do it. Further, a mask in which a support frame is fixed to the inside of the mask main body and is integrated may be used.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings. In this example, three rows of the pleats 4 are arranged on a mask material in which a filter material is sandwiched between non-woven skins,
The mask main body 2 is obtained by heat-sealing both side edges, and the mounting cords 3 are arranged on both outer sides of the mask main body 2, which are arranged on the mask 1 when the mask 1 is widely used.

First, as shown in FIG. 1, the supporting frame is formed by forming a thin polypropylene plate into an oval shape. This is described as an oval support plate 6a below. On one surface of the oval support plate 6a, a temporary fastening, which is a side having hooks and hooks of a so-called magic fastener (registered trademark) composed of a hook side and a loop side at a position slightly shifted from both end portions 8 to a central bridge portion 9 Two tools 7 are attached by heat fusion.

When this is used, as shown in FIG. 2, first, when the pleats 4 of the mask body 2 are expanded and inflated, the pleats remain unexpanded at both side edge portions 5. And, of the three rows of pleats 4, the middle pleats 4
Both end portions 8 of the oval support plate 6a are inserted into the valley fold 4a. Here, the oval support plate 6a has both end portions 8
Since it is made of the thin plate including the above, it can be easily inserted into the valley fold 4a. At this time, if the temporary fastener 7 faces the mask body 2, the temporary fastener 7
Of the non-woven fabric is caught by the fibers of the non-woven fabric and is prevented from being displaced with respect to the mask body 2. Further, the both end portions 8 are received and fixed to the closed portions at both side edges 5 of the valley fold 4a of the pleat 4. At this time, as shown in FIG. 1, the temporary stopper 7 is arranged at a position closer to the bridging portion 9 from the both end portions 8 of the oval support plate 6a. The temporary fastener 7 can be inserted so as not to be caught by the nonwoven fabric of the mask body 2 when it is inserted into the valley fold 4a. After this, the user's face 10 is worn. Then, as shown in FIG. 3 and FIG. 4, the mask main body 2 is attached by being pulled by the attachment cord 3 so that the peripheral portion of the mask body 2 fits the face. The bridging portion 9 between the both end portions 8 is curved in an arch shape together with the mask body 2. Since the mask body 2 is supported by the bridging portion 9 from the inside and keeps its bulge, it does not stick to the mouth of the user 10 and the breathing is reduced. Incidentally, FIG. 4 is an end view including a cross section of the attachment string 3 as seen from AA ′ in FIG. 3. Here, with respect to the temporary fastener 7, the method of hooking the hook side of the magic fastener directly on the non-woven fabric is not the original use of the magic fastener, but an organic solvent is used unlike an adhesive or an adhesive. Since it does not smell and has little odor, it is suitable for disposing the oval support plate 6a on the mask 1.

Since the oval support plate 6a is formed by forming a polypropylene flat plate into an oval shape, it can be manufactured by a relatively simple operation of punching out the polypropylene plate.
Therefore, the manufacturing cost can be suppressed and the manufacturing cost can be reduced, and since the manufacturing cost is suitable, the manufacturing cost can be reduced. Therefore, even if the mask shape retention tool of this example is disposable, there is little trouble. By making the mask holder with the mask 1 disposable, it is easy to keep it hygienic.

Next, when the mask 1 is not used,
As shown in FIG. 5, the pleats 4 of the mask 1 removed from the face of the user 10 are folded and the mask body 2 is removed.
Flatten and store. At this time, since the oval support plate 6a is originally made of a thin plate, that is, has a flat plate shape, it can be accommodated in the valley fold 4a of the pleat 4. It is convenient for storage if it is stored in this way. Further, since the oval support plate 6a is originally flat, it is easy to make it thin and compact, and it is difficult to occupy a place when it is stored and transported. Therefore, the mask 1
Together with this, it is convenient for storage and transportation, and even if it is included in the package of the mask 1, for example, the dryness does not increase, which is convenient.

Next, a second example will be described with reference to FIGS. 6 and 7. In this example, the support frame is an elongated rectangular thin plate made of polypropylene, which will be described below as a rectangular support plate 6b. As shown in FIG. 7, the rectangular support plate 6b is sandwiched in advance in the valley folds 4a of the pleats 4 of the mask body 2, and its both end portions 8 together with both side edges 5 of the mask body 2 are heated. It is fused and fixed.

Therefore, according to this example, substantially the same usage and effect as the first example can be expected, and particularly in this example, since the rectangular support plate 6b is fixed to the mask main body 2 in advance, at the time of use. There is no need to attach the rectangular support plate 6b to the mask 1 one by one. Further, since the both end portions 8 are securely fixed to the both side edges 5 of the mask body 2, even when the pleat 4 is expanded as shown in FIG. 6, an auxiliary fixing means such as the temporary fastener 7 is provided. Easy to make cheaper without need.

Next, a third example will be described with reference to FIGS. 8 and 9. In this example, the support frame is a thin rod made of nylon, and a fishing line having a large diameter is actually used in this example. This is described below as a beam-shaped support rod 6c. Three beam-shaped support rods 6c are used in this example, and as shown in FIG. 9, the beam-shaped support rods 6c are sandwiched in the valley folds 4a of the three pleats 4 of the mask main body 2 in advance, respectively. Both end portions 8 are heat-fused and fixed together with both side edges 5 of the mask body 2. Here, the fishing line made of the nylon material has a well-developed mass-production technology and can be manufactured at low cost, and it can be cut into a predetermined length and used as the beam-like support rod 6c for the present invention. .

Therefore, according to this example, substantially the same usage and effect as in the first example can be expected, and in particular, in this example, the beam-shaped support rod 6c is preliminarily provided with the mask main body 2.
Since it is fixed, it is not necessary to attach the beam-shaped support rod 6c to the mask 1. Further, as in the case of the second example, the both end portions 8 are securely fixed to the both side edges 5 of the mask main body 2, so that the temporary fastener is also used when the pleat 4 is expanded as shown in FIG. No auxiliary fixing means such as 7 is required, and the cost can be further reduced.

[0016]

As described above, since the mask body is supported from the inside and the bulge is maintained, the user's breathing can be reduced. Further, according to the mask retainer of the present invention, the bridge portion of the support frame is curved together with the mask main body to receive the bulge of the mask main body when the user uses the three-dimensional structure beforehand. It does not require shaped members. Therefore, when the supporting frame is manufactured, it can be manufactured in the flat shape such as the flat plate shape or the rod shape, and therefore, it is easy to manufacture at low cost by using the relatively simple work such as the punching or the simple cutting. Therefore, the mask shape retention tool of the present invention is practical for use in the above-mentioned thin mask, and there is little trouble in making it disposable together with the mask. Therefore, it is effective in terms of hygiene. Further, since the mask shape retention tool of the present invention can be stored and transported in the planar shape such as the flat plate shape or the rod shape except when it is used by the user, it can be made thin and compact, which is very convenient for storage and transportation. is there. In addition, the mask is also thin and compact like the mask retainer of the present invention, which is convenient when storing and transporting them together.
