Abstract

In the past, when various types of processing are applied to the inner side of a mask main body, circulation of air for breathing may be obstructed, and the following drawbacks arise, for example: the price of a mask becomes high and same cannot be applied to disposal masks; or such masks are bulky when stored or carried and are difficult to use.　The present invention relates to a mask that solves the above problems by installing, in the vicinities of both of the right end and the left end of the mask, end parts of a drawing body having a pulling function, such as an elastic body, such that the central part of the mask main body is formed to have an anteriorly bulged shape.

Description

mask

The present invention relates to the structure of a mask used for medical purposes and the like.

Conventionally, masks are used for various purposes, but they are often worn and used mainly to protect them from infectious diseases such as influenza.

Such a normal mask is used by covering the nose and mouth with a substantially rectangular mask body made of cloth or non-woven fabric, but the mask body has been devised in various ways so that the wearer can easily breathe.

For example, one example is to arrange a spacer inside the mask body so that the space between the back of the mask and the mouth and nose can be as large as possible.

Utility model registration No. 3222103

However, if the inside of the mask body is processed to form a breathing space, the air flow for breathing may be obstructed, and the mask processing becomes complicated and expensive, so that it cannot be applied to a disposable mask. Furthermore, there are drawbacks such as the fact that the mask is bulky and difficult to use for storage and carrying.

The present invention has been made in view of such circumstances, and the central portion of the mask body is bulged forward by erection of both ends of an attracting body having a pulling function such as an elastic body in the vicinity of both left and right ends. The above problem was solved by forming the above.

In order to solve the above-mentioned conventional problems, in the mask according to the present invention, both ends of a pulling body having a pulling function are erected inside the mask main body in the vicinity of both left and right ends to pull both sides of the mask main body. It is characterized in that the central portion is configured to bulge forward.

The mask according to the present invention is also characterized in the following points.
(2) The pulling body to be erected at both ends of the mask body is configured by folding back the lower left and right ends of the lower edge of the mask body and connecting both ends of the pulling body to this folded part.
(3) Both ends of the pulling body to be erected at both ends of the mask body shall be detachably connected to the left and right sides of the mask body.
(4) The attracting body is composed of an elastic body at the center and an inelastic body at both sides thereof.

According to the first aspect of the present invention, the central portion of the mask body is bulged forward by erection of both ends of the pulling body having a pulling function in the vicinity of the left and right ends inside the mask body and pulling both ends of the mask body. By forming a free breathing space in the inner space, the wearer can breathe freely and comfortably, and it is possible to avoid the difficult situation of breathing due to wearing the mask. There is.

Also, in recent years, there has been a problem that it is difficult to hear the voice in the mask while keeping the "social distance", which is said to prevent coronavirus infection, when talking while wearing the mask, but a free breathing space is formed in the inner space. This has the effect of making the conversation easier to hear without muffled voice.

In addition, by forming a free breathing space in the inner space, the heat does not stay inside the mask when worn, which has the effect of reducing the risk of heat stroke when exercising in the summer.

According to the invention of claim 2, the pulling body erected at both ends of the mask body is configured by folding back the lower left and right ends of the lower edge of the mask body and connecting both ends of the pulling body to the folded portion. There is an effect that a free breathing space can be effectively formed by the space under the nostril formed by lifting by the apex and the bulging space under the mask formed by the attracting body under the nostril.

In addition, since the pulling body is stretched to the lower part of the mask body, the pulling body is placed at a position crossing the nose when the mask is worn, and at the same time, it comes into contact with the surface of the nose. An air flow space for breathing is also created between them, and the synergistic function of the free breathing space and the air flow space allows the wearer to freely and comfortably from the nose and mouth while being a mask covering the nose and mouth. It has the effect of being able to perform breathing movements.

In addition, the conventional mask that is worn by hanging the lower part of the mask on the chin has the disadvantage that when the chin is moved during conversation, the mask lowers downward and the nose is exposed. By bulging the lower part, the mask body is not affected by the movement of the jaw and has the effect of preventing the mask from shifting.

According to the third aspect of the present invention, both ends of the pulling body erected at both ends of the mask body are detachably connected to the left and right sides of the mask body, so that the pulling body is removed as necessary and only the mask is used. It can also be worn.

In addition, since both ends of the pulling body are detachably connected to the left and right sides of the mask body, it has the effect of suppressing bulkiness during transportation and storage by removing it.

According to the invention of claim 4, the attracting body is composed of an elastic body at the central portion and an inelastic body at both sides thereof, whereby the central portion of the mask is intensively contracted as much as possible and both side portions thereof. By putting it in a normal or relaxed state, it is possible to facilitate swelling due to austerity of the central part of the mask body, and to form a free breathing space more effectively.

It is a back view which shows the mask of this invention. It is a front surface which shows the mask of this invention. It is a bottom view which shows the mask of this invention. It is a schematic side view which shows the use state of the mask of this invention. It is a schematic bottom view which shows the use state of the mask of this invention. It is a back view which shows the other embodiment which concerns on the mask of this invention. It is a back view which shows the other embodiment which concerns on the mask of this invention.

The gist of the present invention is that the central portion of the mask body is bulged forward by erection of both ends of the pulling body having a pulling function in the vicinity of the left and right ends inside the mask body and pulling both ends of the mask body. It is in the configuration of.

In addition, the pulling body to be erected at both ends of the mask body is configured by folding both the left and right ends of the lower edge of the mask body and connecting both ends of the pulling body to this folded part, and erected at both ends of the mask body. Both ends of the pulling body are detachably connected to the left and right sides of the mask body, and the pulling body is characterized in that the central part is an elastic body and both sides thereof are inelastic bodies.

Hereinafter, examples of the 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 and has a 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, showing aspects of the mask of the present invention. FIG. 4 is a schematic side view of the used state, and FIG. 5 is a schematic bottom view of the used state, showing the action 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, in a square mask body M formed of a material such as gauze or non-woven fabric, folded portions 1 for inserting strings are formed on both side edges thereof, and the folded portions 1 are annular. The locking string 2 is inserted, and the mask is attached by hanging the locking string 2 on the wearer's ear and covering the mouth with the mask body M.

The main point of the present invention is that in such a mask, as shown in FIGS. 2 and 3, both ends of the pulling body 5 having a pulling function are erected inside the mask main body M in the vicinity of the left and right both ends 3 to form both side portions of the mask main body M. The mask main body M central portion 4 is configured to bulge forward by being pulled toward the center.

The pulling body 5 is made of an elastic body and is formed in a string shape or a band shape. Therefore, if both ends 9 of the pulling body 5 are erected inside the mask main body M in the vicinity of the left and right both ends 3 of the mask main body M, both side portions of the mask main body M are provided. Will be drawn to the center.

The formation of the protruding shape of the central portion 4 of the mask is a technical problem which is the object of the present invention. In the wearing form of a general mask, the back side of the mask directly covers the nose and mouth, but in the present invention, FIG. 4 shows. As shown, since the central portion 4 of the mask body M protrudes forward in a bulging state in the wearing state, a breathing free space S1 is formed in the inner space of this protruding portion, and the wearer can breathe freely and comfortably. It is possible to avoid the situation where it is difficult to breathe due to wearing a mask.

Further, as shown in FIG. 1, the attracting body 5 erected on the left and right ends 3 of the mask body M has triangular shapes at the left and right ends 3 of the lower edge portion of the mask body M, that is, the corners of the lower left and right ends 3 of the mask body M. It can be folded back and connected to both ends 9 of the attracting body 5 to the triangular folded-back portion 1.

The connection form of the both ends 9 of the attracting body 5 may be any connection means such as when the insertion hole 6 formed in the folded-back portion 1 as shown in FIG. 1 is used, when it is sewn and fixed, or when it is fixed with an adhesive. ..

By setting the position of continuous connection with the mask at both ends 9 of the attracting body 5 to the left and right ends 3 of the lower edge portion of the mask body M in this way, the pulling form of the mask body M is limited to the lower left and right sides of the mask body M. Therefore, the pulling allowance becomes larger toward the lower part of the square mask, and the pulling allowance becomes smaller toward the upper part.

In such a state, as shown in FIG. 4, the upper part of the mask lifted by the top of the nose 7, the space s1 below the nostril formed by the lifting by the top of the nose 7, and the lower part of the mask formed by the attracting body 5 below the nostril. The free breathing space S1 is formed by the bulging space s2.

In this way, the position and shape of the free breathing space S1 change depending on the arrangement position of the attracting body 5, and in particular, by connecting the attracting body 5 to the left and right ends of the lower edge of the mask body M as described above, effective breathing is performed. Free space S1 is formed.

Further, when the pulling body 5 is stretched under the mask main body M, as shown in FIG. 5, the pulling body 5 is arranged at a position crossing the jaw 8 when the mask is worn, and hits the surface of the jaw 8. Since they are in contact with each other, an air flow space S2 for breathing is also generated between the mask body M and the surface of the jaw 8.

Therefore, when the mask of the present invention is worn, the wearer can cover the nose and mouth by the synergistic function of the breathing free space S1 in the central portion 4 of the mask body M and the above-mentioned S2 in the lower part of the mask body M, but the nose and mouth. You can breathe freely and comfortably.

Further, the conventional mask that covers the mouth from the nose has a drawback that the lower part of the mask body hangs on the chin, and when the chin is moved by conversation or the like, the mask shifts downward due to the movement of the chin and the nose is exposed. In the mask, the pulling body 5 is hooked on the jaw, and at the same time, the lower part of the mask body M bulges out and does not come into contact with the jaw. Therefore, the mask body M is not affected by the movement of the jaw and the mask can be prevented from shifting.

As another embodiment, both ends 9 of the pulling body 5 erected on the left and right ends 3 of the mask main body M can be detachably connected to the left and right sides of the mask main body M as shown in FIG. With this configuration, if it is not necessary to wear the mask on the majority of the face in close contact, it is possible to remove 4 and wear only the mask.

Further, the attracting body 3 can be composed of an elastic body at the central portion 10 and an inelastic body at both end portions 9.

That is, by constructing in this way, the central portion 4 of the mask main body M is intensively contracted as much as possible, and both side portions thereof are in a normal or relaxed state, so that the central portion 4 of the mask main body M is particularly contracted. The accompanying swelling can be facilitated and the formation of the free breathing space S1 can be facilitated.

Further, as another embodiment, the locking string 2 and the pulling body 5 of the mask main body M can be formed in a loop shape by one common string body 11 as shown in FIGS. 7a and 7a and b.

The common string body 11 is inserted into an insertion hole 12 formed by drilling in each of the four corners of the square mask body M.

At the time of the insertion, either one of the insertion holes 12 formed in the upper end of the mask main body M is inserted as a starting point, and the other insertion hole 12 is inserted in order as the ending point.

That is, when the insertion hole 12 on the upper right side is used as the starting point, the common string body 11 is inserted into the insertion hole 12 from the front side of the mask body M, and then the common string body 11 is inserted into the insertion hole 12 on the lower right side from the back side to the front side. Will be done.
The common string 11 inserted into the lower right insertion hole 12 is then inserted into the lower left insertion hole 12 from the front side of the mask body M, and finally is inserted into 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 at two locations on the right side and the left side respectively holds the locking string 2 at both lower ends. The common string body 11 inserted into the insertion hole 12 of the above forms the attracting body 5.

The insertion hole 12 may use eyelet metal fittings or the like to reinforce the hole. Further, the upper insertion hole 12 is for fixing both ends of the common string body 11, and may be directly fixed to the mask main body M by using, for example, heat welding instead of the insertion hole 12.

Further, an adjusting tool 13 for adjusting the length is attached to the middle part of the locking string 2. The adjusting tool 13 has a size adjusting function according to the size of each wearer and a function of forming a bulging space s2 depending on the degree of adjustment.

As described above, by integrally forming the locking string 2 and the pulling body 5 with the common string body 11, it can be comfortably attached regardless of the size of each person.

Further, the function of forming the bulging space s2 can be used as a normal mask by loosening the adjusting tool 13 downward when the free breathing space S1 is unnecessary, and tightening the adjusting tool 13 upward when the free breathing space S1 is required. Can be changed promptly.

In addition, if the mask is worn for a long time, pain may be felt on the back side of the ear, but the locking string 2 and the pulling body 5 are formed by the common string body 11, and the tightening condition is adjusted by the adjusting tool 13. By being able to do this, it is possible to relieve the pain on the back of the ear caused by wearing it for a long time.

In FIG. 7b, the adjusting tool 13 is provided on the left and right sides of the pulling body 5, so that finer adjustment is possible.

That is, by adjusting the locking string 2 on the left and right respectively, it is possible to more appropriately tighten each person.

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