Description

The present invention relates to the structure of a mask for medical use etc.

Traditionally, masks have been used for a variety of purposes, but they are primarily worn to protect against infectious diseases such as influenza.

Such a normal mask is used by covering the nose and mouth with a roughly rectangular mask body made of cloth or nonwoven fabric, and various features are incorporated into the mask body to make it easier for the wearer to breathe.

For example, one example would be to place a spacer inside the mask body to maximize the distance between the back of the mask and the mouth and nose.

However, processing the inside of the mask body to create a breathing space can impede the flow of air for breathing, and the mask processing is complicated and expensive, making it impossible to use as a disposable mask.Furthermore, the masks are bulky and difficult to store and carry, making them difficult to use.

The present invention was made in consideration of the above circumstances, and solves the above problem by bridging both ends of a pull-in body having a pulling function such as an elastic body near both left and right ends, thereby forming the central part of the mask body to bulge forward.

In order to solve the above-mentioned problems of the conventional mask, the mask of the present invention is characterized in that it is configured such that a pulling body having a pulling function is installed at both ends near both left and right ends inside the mask body, pulling both sides of the mask body together, causing the center of the mask body to bulge forward.

The mask according to the present invention is also characterized in the following respects.
(2) The pulling body to be installed at both ends of the mask body is constructed by folding back both left and right ends of the lower edge of the mask body and connecting both ends of the pulling body to the folded back parts.
(3) The ends of the attracting body that are bridged over both ends of the mask body are detachably connected to the left and right sides of the mask body.
(4) The center of the pulling body is made of an elastic material, and both sides of the center are made of a non-elastic material.

According to the invention of claim 1, a pulling body having a pulling function is disposed at both ends near both left and right ends inside the mask body, and by pulling both sides of the mask body together, the central part of the mask body is configured to bulge forward. This creates a free breathing space in the inner space, allowing the wearer to breathe freely and easily, and has the effect of avoiding the difficult breathing conditions that come with wearing a mask.

In addition, in recent years, there has been an issue with people talking while wearing a mask and maintaining "social distance" as a measure to prevent coronavirus infection, as voices become muffled inside the mask and are difficult to hear. However, by creating a free breathing space inside the mask, voices do not become muffled and conversations become easier to hear.

In addition, by creating a free breathing space inside the mask, hot air does not build up inside the mask when it is worn, which helps reduce the risk of heat stroke when exercising in the summer.

According to the invention of claim 2, the pulling bodies installed at both ends of the mask body are constructed by folding back both left and right ends of the lower edge of the mask body and connecting both ends of the pulling bodies to these folded parts, which has the effect of effectively forming a free breathing space by the space below the nostrils formed by the lifting of the nose tip and the bulging space below the nostrils formed by the pulling bodies.

In addition, since the pulling body is stretched under the mask body and positioned across the chin when the mask is worn, it also comes into contact with the surface of the chin, creating an air circulation space for breathing between the mask body and the surface of the chin. The synergistic effect of the free breathing space and the air circulation space allows the wearer to breathe freely and easily through their nose and mouth, even though the mask covers them.

In addition, conventional masks, which are worn by hanging the bottom under the chin, have the drawback that when moving the chin during conversation, the mask will slide down and expose the nose. However, with the new mask, the pulling body comes into contact with the surface of the chin and the bottom of the mask bulges out, so the mask body is not affected by jaw movement and prevents the mask from slipping off.

According to the invention of claim 3, the ends of the pull-in body that are attached to both ends of the mask body are detachably connected to the left and right sides of the mask body, so that the pull-in body can be removed as necessary and only the mask can be worn.

In addition, both ends of the pull-in body are detachably connected to the left and right sides of the mask body, which has the effect of reducing bulk during transportation and storage by removing them.

According to the invention of claim 4, the pulling body is made of an elastic material in the center and a non-elastic material on both sides, so that the center of the mask is contracted as much as possible while the both sides are left in a normal or relaxed state, which makes it easier for the mask body to expand as the center of the mask contracts, and more effectively creates a free breathing space.

FIG. 11 is a rear view showing another embodiment of the mask of the present invention.

The gist of this invention is that a pulling body with a pulling function is installed at both ends near both left and right ends inside the mask body, pulling both sides of the mask body together so that the center of the mask body bulges forward.

The mask body is also characterized in that the pulling body is constructed by folding back the left and right ends of the lower edge of the mask body and connecting both ends of the pulling body to these folded parts, that both ends of the pulling body are connected to the left and right sides of the mask body so as to be freely attached and detached, and that the pulling body is constructed such that the center part is made of an elastic material and both sides are made of a non-elastic material.

Hereinafter, an embodiment of a mask according to the present invention will be described in detail with reference to the drawings.
Fig. 1 is a rear view of the mask of the present invention, which has the basic configuration of the mask of the present invention. Fig. 2 is a front view of the mask of the present invention, and Fig. 3 is a bottom view of the mask of the present invention, which show the embodiment of the mask of the present invention. Fig. 4 is a schematic side view of the mask in use, and Fig. 5 is a schematic bottom view of the mask in use, which shows the function and effect of the mask of the present invention. Fig. 6 is a rear view showing another embodiment of the mask of the present invention.

That is, as shown in FIG. 1, the mask body M is made of a material such as gauze or nonwoven fabric and has folded-over sections 1 on both side edges for inserting strings. A ring-shaped fastening string 2 is inserted into the folded-over section 1. The mask is worn by hanging the fastening string 2 around the wearer's ears and covering the mouth with the mask body M.

The gist of the present invention is that in such a mask, as shown in Figures 2 and 3, both ends of a pulling body 5 having a pulling function are installed on the inside of the mask body M near both left and right ends 3, and the both sides of the mask body M are pulled toward the center, so that the central portion 4 of the mask body M bulges forward.

The pulling body 5 is made of an elastic material and is formed in a string or band shape, so that by bridging both ends 9 of the pulling body 5 inside the mask body M near the left and right ends 3 of the mask body M, both sides of the mask body M will be pulled toward the center.

The formation of such a protruding shape in the central portion 4 of the mask is the technical objective of the present invention. When a typical mask is worn, the back of the mask directly covers the nose and mouth. However, in the present invention, as shown in FIG. 4, the central portion 4 of the mask body M protrudes forward in a bulging shape when worn, forming a free breathing space S1 in the inner space of this protruding portion, allowing the wearer to breathe freely and easily and avoiding the difficult breathing conditions that accompany wearing a mask.

As shown in FIG. 1, the pulling body 5 installed on both left and right ends 3 of the mask body M can be constructed by folding back the left and right ends 3 of the lower edge of the mask body M, i.e., the corners of both left and right ends 3 of the lower part of the mask body M, into a triangle and connecting both ends 9 of the pulling body 5 to this triangular folded portion 1.

The connection form of both ends 9 of the pulling body 5 can be any means, such as using an insertion hole 6 drilled in the folded portion 1 as shown in Figure 1, fixing by sewing, or fastening with an adhesive.

By setting the connection positions of both ends 9 of the pulling body 5 with the mask at the left and right ends 3 of the lower edge of the mask body M in this manner, the pulling shape of the mask body M is limited to the left and right lower parts of the mask body M, so that the pulling allowance becomes greater towards the bottom of the square mask and becomes smaller towards the top.

In this state, as shown in Figure 4, a free breathing space S1 is formed by the upper part of the mask lifted by the nose tip 7, the space s1 below the nostrils formed by the lifting by the nose tip 7, and the bulging space s2 of the lower part of the mask formed by the pulling body 5 below the nostrils.

In this way, the position and shape of the free breathing space S1 changes depending on the position of the pulling body 5, and in particular, by connecting the pulling body 5 to the left and right ends of the lower edge of the mask body M as described above, the free breathing space S1 is effectively formed.

Furthermore, when the pulling body 5 is stretched over the lower part of the mask body M, as shown in Figure 5, the pulling body 5 is positioned across the chin 8 when the mask is worn and abuts against the surface of the chin 8, so that an air circulation space S2 for breathing is also created between the mask body M and the surface of the chin 8.

Therefore, when the mask of the present invention is worn, the synergistic function of the free breathing space S1 in the central part 4 of the mask body M and the above-mentioned S2 in the lower part of the mask body M allows the wearer to breathe freely and easily through their nose and mouth, even though the mask covers them.

In addition, conventional masks that cover the nose and mouth have the disadvantage that the lower part of the mask body rests on the chin, so when the chin is moved during conversation, the movement of the chin causes the mask to shift downwards, exposing the nose. However, with the mask of the present invention, as soon as the pulling body 5 rests on the chin, the lower part of the mask body M bulges out and no longer comes into contact with the chin, so that the mask body M is not affected by the movement of the chin, and the mask can be prevented from shifting.

As another embodiment, both ends 9 of the puller 5 that are installed on both the left and right ends 3 of the mask body M can be detachably connected to the left and right sides of the mask body M as shown in Figure 6. By configuring it in this way, when it is not necessary to wear the mask closely on more than half of the face, 4 can be removed and the mask alone can be worn.

In addition, the attraction body 3 can be constructed such that the central portion 10 is made of an elastic material and both end portions 9 are made of a non-elastic material.

In other words, by configuring it in this manner, the central portion 4 of the mask body M is contracted as much as possible and both side portions are left in a normal or relaxed state, which makes it easier for the central portion 4 of the mask body M to expand as a result of contraction, and facilitates the formation of a free breathing space S1.

In another embodiment, the retaining string 2 and the pulling body 5 of the mask body M can be formed into a loop shape with a single common string body 11, as shown in Figures 7a and b.

The common string 11 is inserted through holes 12 formed at each of the four corners of the rectangular mask body M.

When inserting, one of the insertion holes 12 drilled at both upper ends of the mask body M is used as the starting point, and the other insertion hole 12 is used as the ending point.

That is, when the upper right insertion hole 12 is used as the starting point, the common string 11 is inserted through the insertion hole 12 from the front of the mask body M, and then through the lower right insertion hole 12 from the back to the front.
The common string 11 inserted through the lower right insertion hole 12 is then inserted through the lower left insertion hole 12 from the front side of the mask body M, and finally inserted through the upper left insertion hole 12 from the back to the front.

By inserting the common string body 11 into the insertion hole 12 as described above, the common string body 11 inserted into the insertion holes 12 drilled in two places on each of the right and left sides forms the locking string 2, and the common string body 11 inserted into the insertion holes 12 at both lower ends forms the pulling body 5.

It is advisable to use eyelets or the like to reinforce the insertion holes 12. The upper insertion holes 12 are for fixing both ends of the common string 11, and may be fixed directly to the mask body M using, for example, heat welding instead of through the insertion holes 12.

In addition, an adjustment tool 13 for adjusting the length is attached to the middle of the fastening cord 2. The adjustment tool 13 has a size adjustment function to match the size of each wearer and a function to form a bulging space s2 depending on the degree of adjustment.

As described above, by forming the locking cord 2 and the pulling body 5 as a single unit using a common cord body 11, the device can be worn comfortably regardless of the size of each individual.

In addition, the function of forming the bulge space s2 allows the mask to be used as a normal mask by loosening the adjustment device 13 downward when the free breathing space S1 is not required, and when the free breathing space S1 is required, the adjustment device 13 can be tightened upward, allowing for quick changes.

In addition, wearing a mask for a long period of time can cause pain behind the ears, but by forming the retaining string 2 and the pulling body 5 from a common string body 11 and by allowing the tightness to be adjusted using an adjustment device 13, it is possible to alleviate the pain behind the ears caused by wearing the mask for long periods of time.

Figure 7b shows that adjustment devices 13 are provided on both the left and right sides of the pull-in body 5, allowing for finer adjustments.

In other words, by making it possible to adjust the fastening cord 2 on each side, it is possible to provide a more appropriate tightening for each individual.

Although the present invention has been described above through the above-mentioned examples, the present invention is not limited to these. Furthermore, the various effects described above are merely a list of the most favorable effects resulting from the present invention, and the effects of the present invention are not limited to those described in the present examples.
