Description

The present invention comprises a mask sheet, more specifically, a mask sheet that covers the nose and mouth, and a mask sheet mounting frame that holds the mask sheet on the face.

Wearing a mask is obligatory as a measure against infectious diseases such as the new corona, and it is expected that opportunities to wear a mask on a daily basis will continue to increase.

There are already many inventions of masks with high adhesion and airtightness with a focus on infection prevention. Wearing a mask with high adhesion in winter is not so reluctant, but wearing a mask in the summer and rainy season itself is not only unpleasant but also may cause heat stroke.

It is more effective to wear a mask with high adhesion to prevent infection, but on the other hand, if the mask has high adhesion, the so-called triple pain, suffocation, difficulty in conversation, stuffiness in the mask, etc. The higher it is, the more it occurs. However, removing the mask from these discomforts is a mess.

Further, the spectacle wearer and the eye shield wearer are suffering from the problem that the exhaled air leaking from the mask is not sufficiently exhausted and the spectacles and the eye shield become cloudy and the visibility is obstructed.

The main issue in the development of current masks is how to ensure breathability while achieving high adhesion.

On the other hand, since droplets caused by coughing and conversation are mainly scattered in the forward direction, even if the adhesion is not so high, it is possible to prevent droplet infection from others and to prevent the scattering of own droplets. , It seems that it is effective enough to cover the front of the mouth and nose gently. Instead of removing the mask because you can't stand the suffocation and heat, you can use a breathable mask that can be worn comfortably for a long time and a highly airtight mask depending on the place of use and the situation. How to use the mask is required.

In today's society, where it is expected that masks will be worn on a daily basis as a countermeasure against infectious diseases such as the new coronavirus, it is expected that masks designed to reduce discomfort caused by wearing masks will become more and more necessary in the future.

By the way, there are an invention of Cited Document 1 and an idea of Cited Document 2 as a conventional technique including a sheet for protecting a face and a mounting frame.

The invention of the eye shield and the frame described in Patent Document 1 for protecting the face has been devised to facilitate the wearing of the eye shield, but the eye shield is formed three-dimensionally and the size of the user's face is large. The structure does not adjust the size according to the shape of the pod.

Further, the device described in Cited Document 2 consisting of the face protection mask and the mounting frame is intended to facilitate the attachment / detachment of the face protection mask, and is not devised to ensure breathability. ..

In addition, some cloth masks and other masks with fashionable colors and patterns have come to be seen on the market, but shields with a shape that covers the entire face, such as transparent plastic shields, tend to be large and easy to use. However, the current situation is that masks are not regarded as one of the fashion items to wear due to resistance to wearing.

Therefore, in the present application, we provide a mask sheet and a mounting frame that can secure and adjust the distance between the mask and the face when worn, have excellent breathability, and can be adjusted in size according to the shape of the user's face. The purpose.

Furthermore, the purpose is to make the shape of the mask sheet simple and sophisticated, to freely print on the surface of the mask sheet, to develop various colors and patterns, and to provide a fashionable mask sheet. is there.

In order to solve the above problem, in claim 1 of the present application, a mask sheet having at least a front portion covering the mouth and nose and a leg portion covering the side surface of the face extending to the front portion via a side polygonal line is created. However, a plurality of locking means to the mask sheet mounting frame are provided at symmetrical positions between the vertical central folding line and both ends of the leg in the center of the front portion, and the vertical locking portion is provided between these locking means. It forms a fold line. Further, in claim 2, as a means for locking the mask sheet mounting frame, locking holes or notches are formed at both ends of the leg portion.

A wavy slit that allows the mask sheet to be moved in the vertical direction while inserting the mask sheet mounting frame and the locking means to the mask sheet mounting frame at the center fold line in the direction and the symmetrical positions at both ends of the leg. It has a holding means made of, and forms a vertical locking portion folding line between the locking means and the holding means.

In claim 4 , the locking means for the mounting frame provided on the mask sheet is a locking hole having a notch and partially formed of a breaking line, and when the mounting frame is thin, the notch of the locking hole is provided. The frame is held by the portion, and when the mounting frame is thick, the locking hole is enlarged along the breaking line so that the mounting frame can be held.

In claim 5 , a fold line is formed in an inverted V shape from the central fold line of the front portion.

In claim 6 , a V-shaped fold line is formed below the front surface of the mask sheet from the central fold line toward the left and right side fold lines, and the lower part of the front surface of the mask sheet is folded toward the face to cover the vicinity of the chin. It is a mask sheet that can be used.

In claim 7 , the mask sheet is made of paper, plastic, non-woven fabric, or a combination of these materials, in claim 8 , the mask sheet is made of double transparent plastic, and in claim 9 , the mask sheet of the present application is used. The face protector is provided, which comprises at least a mounting frame composed of a frame front portion on which a nose hook is formed and a frame leg portion connected to the frame front surface portion.

-Since the mask sheet covers at least the front of the mouth and nose, it is effective in preventing droplet infection.

-Since the mask sheet and the mounting frame are connected only at the locking points of the temples, the contact area between the mask sheet and the face can be made as small as possible, and the mask sheet and the skin do not come into close contact with each other. Excellent breathability. Because it has a comfortable wearing feeling without being filled with heat
It can be worn for a long time and can be used comfortably especially in the hot and humid summer.

-Since a gap is created between the mounting frame and the mask sheet, even if the mounting frame is in the shape of spectacles, fogging of the spectacle lens due to exhalation is prevented.

-By making the mask sheet and mounting frame easy to put on and take off, the mask sheet can be disposable and hygienic.

-The mask sheet can be easily attached to and detached from the mounting frame, and the mask sheet can be stably held on the mounting frame regardless of whether the legs of the mounting frame are thin or thick.

-It can be manufactured at low cost by making the mask sheet made of paper or plastic. In addition, it can be folded along a folding line, etc., making it convenient for storage and carrying.

-The mouth and nose are covered with a mask sheet, and the eyeglass-shaped frame acts as an eye shield, so the entire face can be prevented from droplet infection.

-Since the mask sheet attached to the frame can slide back and forth, airtightness and breathability can be adjusted with a single touch by adjusting the distance between the mask sheet and the face. Further, since the mask sheet can be attached to the frame so as to be movable up and down, hydration can be performed while the mask sheet is attached.

-By making the mask sheet made of paper, plastic, etc., it is easy to print various patterns and colors on the surface. For example, when viewed from a distance, the mask pattern (general) is like wearing a mask. It is also possible to dare to print (displaying horizontal folds by printing) like a non-woven mask.

By making the shape of the mask sheet simple and sophisticated, and by freely printing bandana patterns and characters, the mask sheet can be made more convenient as one of the fashion items.

-Since the mask sheet is not in close contact with the skin, there is no feeling of oppression, but the position of the mask sheet is less likely to shift.

-By folding the chin toward the face along the fold line, the chin is covered under the mask sheet and the area around the mouth is completely protected.

-By making the mask sheet transparent (colored or colorless) plastic, you can check the movement and facial expression of your mouth, which makes conversation smoother. Especially helpful for the hearing impaired. In addition, the mask sheet is composed of a double transparent plastic sheet, which can be used as an advertising medium or novelty goods by having a structure in which printed matter can be sandwiched between them, and by replacing the printed matter, the mask sheet can be put on. You can enjoy the replacement.

-The mask sheet can be assembled more three-dimensionally by the inverted V-shaped folding line from the central folding line on the front part. The length of this inverted V-shaped folding line makes it possible to adjust the protruding height of the central part of the mask sheet, and it can be worn by Westerners with a high nose.

Hereinafter, the optimum embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a developed plan view of the mask sheet 1 according to claim 1. The mask sheet 1 is made of boomerang-shaped hard paper and has symmetrical legs 1b-1b extending to the front surface 1a via a front surface 1a and a plurality of side folding lines 3 that cover at least the nose and mouth. Has.

By forming a plurality of side fold lines 3 in the vertical direction, the side fold lines are mountain-folded and valley-folded to adjust the length of the mask sheet 1 according to the size and shape of the face. In this embodiment, the number of side fold lines is three, but the size can be further finely adjusted by making the interval between the side fold lines finer or increasing the number of lines, and the desired size of the mask sheet to match the face. Can be changed to.

The front surface portion 1a has a substantially rectangular shape, but when the upper end portion 1C is formed into an arc shape and is attached to the spectacles, the gap between the spectacle frame and the mask sheet is narrowed along the lower peripheral edge portion of the spectacle frame to face each other. It is possible to prevent splashes from the direction, that is, from the front as much as possible.

A central folding line 2 is formed in the center of the front surface portion 1a in the vertical direction, and the mask sheet 1 can be formed into a three-dimensional structure along the nasal bridge by folding it in a mountain fold and projecting it forward. In addition, it is convenient for storage and carrying when folded compactly along the central folding line 2 or the like.

Two through holes 5 and 6 are formed symmetrically in the leg portion 1b via the locking portion folding line 4. After the locking portion folding line 4 is folded in a valley, the mounting frame is inserted through the through holes 5 and 6 to lock the mask sheet 1 to the mounting frame. At this time, if the through holes 5 and 6 are formed by slightly shifting the positions in the horizontal direction, the movement of the legs of the mounting frame is suppressed, and the mask sheet is stably held by the mounting frame.

The material of the mask sheet 1 may be made of hard paper, a non-woven fabric having a multi-layer structure that is breathable but prevents the invasion of bacteria and the like, and a transparent plastic film (transparent, colored transparent) having elasticity. In addition, any material that can be manufactured in the form of a sheet is not limited to these materials, and can be changed to various materials such as cloth and cardboard.

The mask sheet made of a transparent plastic film allows smooth communication because the mouth and facial expressions can be visually recognized. It is especially suitable for the hearing impaired who communicated by reading their lips.

In the case of non-woven fabric, the front part covering the mouth and nose is made of non-woven fabric, and the legs are manufactured from other materials. The material of the mask sheet is not limited to one, but is composed of a combination of multiple materials. You can also do it.

Further, the mask sheet can be subjected to known processing such as antibacterial processing, polarization treatment for blocking ultraviolet rays, and waterproof processing on the outside to increase added value.

In the mask sheet 7 of FIG. 2, the lower end of the central folding line 8 of the front surface portion 7a is cut out in an inverted V shape, or an inverted V-shaped folding line 9 is formed, and the jaw folding line 10 is formed diagonally upward from the central folding line 8 to the left and right. Form.

By folding the jaw folding line 10 toward the face, the air permeability of the mask sheet 7 and the vicinity of the chin can be adjusted. Further, by setting the lower part 8a of the central folding line and the jaw folding line 10 as breaking lines, the lower part of the mask sheet can be separated to form the front surface portion of the mask sheet compactly when it is not necessary.

By shifting the formation positions of the two through holes that serve as the locking portions of the mask sheet to the mounting frame, the mask sheet can be securely locked to the mounting frame, while the inside of the through holes is slid to position the mask sheet mounting position. Easy to adjust in the front-back direction.

When you want to make the mask airtight, such as in a crowded train, you can secure the airtightness by moving the mask sheet as close to your face as possible and moving it forward when you feel suffocated.

As for the shape of the hole to be the locking portion, in addition to the through hole, as shown in FIG. 3, a notch portion 11 is provided by notching a part thereof, and a part of the insertion hole 12 is cut off to form a breaking line of the mounting frame. When the legs are thin, the notch 11 holds the mounting frame, and when the legs of the mounting frame are thick, the breaking line can be cut to widen the size of the insertion hole 12 to hold the mounting frame. You can.

Further, by forming the chrysanthemum hole-shaped through hole 13 in which the cutout portion 14 and the tongue piece 15 are alternately provided in the through hole, the mask sheet can be reliably held regardless of the thickness of the frame. ..

Further, the shape of the locking portion of the mask sheet is not limited to the through hole as long as it can be attached to and held on the frame, and various locking means such as providing a locking piece on the mask sheet. It can be applied.

As a locking means corresponding to any thickness of the legs of the mounting frame, as shown in FIG. 10, applications such as providing slits 26 and 27 in the shape of vertically connected arcs on the legs of the mask sheet 25 can be applied. It is possible. The shape and number of slits are not limited to those shown in the figure, and can be variously changed.

Further, the wearing frame may have a shape having a nose hook portion and a leg portion to be hung on the ear, and a spectacle shape is generally considered. Of course, you may attach a mask sheet to your glasses.

Further, a U-shaped frame 16 having a nose hook 19 located on the front surface of the face and composed of legs 18 connected to both ends of the mounting frame front surface 17 and the front surface of the mounting frame, and a nose hook 20 are provided. It is possible to apply such as a mounting frame 23 in which a leg portion 22 is connected to a front portion 21 which is composed of only a lower frame of a general front surface portion of an eyeglass frame. When the mask sheet is attached to the mounting frame 23, only the mask sheet is visually recognized when viewed from the front, and the mask sheet has a simple and refreshing impression.

FIG. 7 is an explanatory view showing a state in which the mask sheet 1 of the present application is attached to the spectacles 24, which is a frame for attaching the mask sheet. A method of attaching the mask sheet 1 will be described with reference to FIG. 7.

The unfolded mask sheet 1 shown in FIG. 1 is folded into a mountain so that the central folding line 2 protrudes forward, and the legs covering the side surface of the face are folded at approximately 90 degrees along the side folding line 3. At this time, if the side fold lines are formed in a bellows shape of mountain folds and valley folds according to the width of the face and the spectacle frame, the width of the front portion of the mask sheet and the length of the legs can be adjusted. Subsequently, the tip of the leg of the spectacles 24 is inserted into the through hole 5 from the inside of the mask sheet 1, and then communicates with the through hole 6 from the outside. At this time, the locking portion folding line 4 formed in the vertical direction between the two communication holes is folded in a valley. The tips of the other legs of the spectacles 24 are similarly inserted into the through holes 5 and 6.

When the spectacles 24 equipped with the mask sheet 1 are hung, only the locking portion folding line 4 of the mask sheet 1 comes into contact with the side surface of the face (near the temple), and between the spectacles 24 and the mask sheet 1 or with the mask sheet 1. A sufficient gap is created between the face and the face, and breathability can be ensured.

On the other hand, if the exhaled air still stays in the mask sheet, the gap between the glasses 24 and the mask sheet 1 and the gap between the face and the mask sheet 1 can be further widened by sliding the mask sheet 1 forward. It is. A and b of FIG. 8 show the state.

The mask sheet can be moved forward by sliding the legs of the spectacles held in the through hole from the wearing state of FIG. 8a, and as shown in FIG. 8b, between the spectacles and the mask sheet, that is, with the face. A sufficient gap is created between the mask sheet and the mask sheet to exhaust the hot air in the mask sheet at once, and the air permeability can be ensured.

Further, even when the mask sheet is worn on the eyeglasses, the mask sheet can be folded into a small size together with the eyeglasses by folding along the side folding line, which is convenient for storage and carrying (Fig. 9).

When the mask sheet is made of a transparent plastic sheet, the structure is almost the same as that of the paper mask sheet. On the other hand, when the mask sheet is made of non-woven fabric, a hard shape-retaining member (wire, wire, etc.) made of a flexible material at the contact portion of the nasal bridge so that the mask sheet can be held three-dimensionally according to the shape of the nasal bridge. It is preferable to mount the mask sheet (bone, etc.). It is easy to mass-produce the mask sheet with a Thomson type punching machine, etc., and the mounting frame can also be manufactured at low cost by integrally molding the synthetic resin.

The means for locking the mask sheet and the mounting frame include not only inserting the mounting frame leg into the through hole, but also fitting the hinge shaft provided on the outside of the mounting frame leg with the locking hole of the mask sheet. Means are conceivable. The mask sheet can be tilted freely with the hinge shaft as a fulcrum, and the mask sheet can be raised toward the head to replenish water (not shown).

Further, the mask sheet 28 shown in FIG. 11 has a structure in which the mask sheet can be temporarily raised on the head while being locked to the mounting frame. The mask sheet 28, which is composed of the mask sheet front surface portion 28a and the mask sheet leg portion 28b, is provided with through holes 29 and 30 for locking the mounting frame in the mask sheet leg portion 28b, and the through holes 30. The mounting frame holding piece 31 is formed diagonally downward. The holding piece 31 is composed of a breaking line except for a part, and is folded inside the mask sheet along the breaking line. When the mask sheet 28 is temporarily held upward, the tip of the leg of the mounting frame (not shown) is inserted through the through hole 29 from the inside to the outside, and the mask sheet 28 is moved onto the mounting frame. The holding piece 31 protruding inside the mask sheet is locked to the mounting frame to hold the mask sheet 28. When the mask sheet 28 is unlocked by the holding piece 31, the mask sheet 28 returns to its original position, that is, the front of the face.

By allowing the mask sheet to move up and down, it is possible to rehydrate while wearing the mask sheet, and by holding the mask sheet near the forehead with a holding piece, the mask sheet can be used like a sun visor. You can also.

As another embodiment of the mounting frame locking means, in FIG. 13, a plurality of arcuate slits 36 are provided in the legs of the mask sheet 35. When the slit through which the end of the mounting frame is inserted is first selected and the end of the mounting frame is inserted into the locking hole 37, the locking angle of the mounting frame can be changed with the locking hole 37 as a support shaft, which is desired. The mask sheet 35 can be held on the mounting frame at an angle.

Further, in FIG. 11, an inverted V-shaped folding line 33-33 is formed below the central folding line 32 provided on the front surface portion 28a of the mask sheet 28. By folding the central fold line 32 in a mountain fold, folding the lower end 32b of the central fold line 32 in a valley fold, and further folding the inverted V-shaped fold line 33-33 into a mountain fold, the central fold line 32 can be projected more three-dimensionally and stably. You can.

Further, the protruding state of the central portion of the mask sheet can be adjusted by changing the length and angle of the inverted V-shaped folding line. If it is formed long like the inverted V-shaped folding line 34 shown in FIG. 11, the three-dimensional effect is further increased (see FIG. 12).

By forming a plurality of the inverted V-shaped folding lines, it is possible to adjust the height of the user's nose and the state of protrusion of the mask sheet in the forward direction according to his / her preference. As a result, users with a high nose, such as Westerners, can use the mask sheet of the present application without feeling oppressive.

Further, when a mask sheet having a double structure of a colorless transparent or colored transparent plastic film is prepared (see FIG. 14), a printed matter can be sandwiched between the plastic films. FIG. 14 is a developed plan view of a mask sheet having a double structure of a transparent plastic film.

Between the double-structured mask sheets, insert a printed matter based on the team color of the team supporting sports, etc. or a printed matter with a logo, or insert a printed matter of your favorite pattern or pattern and wear the mask sheet. .. Since it functions as an advertising medium for companies and professional sports teams, it can be used as novelty goods.

Moreover, since the printed matter can be easily removed from between the mask sheets, the mask sheet can be changed according to the mood and TPO.

The present invention is not limited to the above-described embodiment, and can be applied, changed, or modified to various different forms without departing from the spirit of the present application.

It can be used as a measure to prevent droplet infection in all aspects of daily life such as medical sites, food production lines, customer service, commuting to school, etc.
