Abstract

<P>PROBLEM TO BE SOLVED: To solve problems wherein a conventional hygienic mask with a main part or a part formed as a transparent body is troublesome in examining a way to compose a filtration part in order to avoid any hindrance in the in/out direction and amount of exhalation if the transparent body is enlarged because the transparent body has no filter function, and a mask in the known art is projected forward wide and large, which calls for consideration on how to hold and keep the mask when removed for a meal or to drink tea. <P>SOLUTION: A mask with the transparent body is composed by vertically integrating the front edges (3) of right and left transparent plates (1), (2) of laterally symmetrical plane shape into an inner surface abutting state to face in a plane, and mounting a filter (5) for purifying air inhaled by a wearer, in a laterally expandable or closable manner between the insides of the lower edges (4), (4) of the right and left transparent plates (1), (2). <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

This invention prevents inhalation of pathogenic bacteria, dust, pollen, etc. through the respiratory tract into human lungs in the fields of preventive medicine, disaster prevention, hygiene, etc. It is a sanitary mask to improve the safety of the world with less.
In particular, the wearer's mouth and cheeks can be seen through from outside the mask during use, and the filter part can be folded and folded while the filter is not worn to keep the filter part clean. It is related with the mask which tries to be stored and carried as a thin.

When a conventional sanitary mask is worn, the lower half of the face is covered and hidden, so that it becomes a disguise prop, or the expression cannot be seen and the voice is muffled, which may interfere with mutual understanding.
Therefore, in recent years, there has appeared a form in which the main part and part of the mask are made transparent and the wearer's facial expression can be seen from the outside.

JP 2009-11475 A Utility Model Registration No. 3148507 JP-T-2006-525823

In conventional sanitary masks, the main part or part of the mask is transparent, the transparent body does not have a filtration function. Further, it has been troublesome to examine how the filtration unit is configured so as not to hinder the direction and amount of exhalation.
The publicly known technique presented by the applicant of the present application as Patent Document 1 is a mask with a transparent portion in which the upper half of the mask is a transparent body and a breathable member made of a nonwoven fabric is attached to the whole or a part of the lower half.

Looking at this known technology in detail, a flat transparent body in the horizontal direction protrudes widely in the upper half in the form of a duck's beak, and the lower half projects in a substantially symmetrical shape below it. A part or the whole of the lower half is used as a breathable member, and how to hold and store the mask that protrudes widely in this way when drinking or drinking tea is considered It is the structure to do.
Each time you throw away what you are using and change it to a new mask, it will cost more, and when you put it in your pocket, turn the filter inward and fold it up to the transparent body in a four-fold shape. If it is left on a desk in a double detachable state, pathogenic bacteria, dust, pollen, etc. are likely to adhere to the filter inner and outer surfaces of the large area breathable member. It consisted of composition.

Next, a known technique presented as Patent Document 2 is a mask body that is three-dimensionally formed like a hemispherical or bivalve shell, and has a resin or rubber having a width of 1/3 to 1/2 of its upper vertical width. It is a three-dimensional mask configuration in which a transparent portion is impregnated with a solution.
In this configuration as well as Patent Document 1, the whole is greatly integrated and protrudes forward in a hemispherical shape. How to hold, store, and remove the mask that has been removed in a state that is too large to fit into the pocket It is something to worry about.

Further, the publicly known technology presented by the present applicant as Patent Document 3 has the same problems as the above-described configuration, and therefore, the differences from the “first to third embodiments” that will not be described are detailed below. The structure of the “fourth form” that clarifies the above is disclosed.
The "fourth form" disclosed in FIGS. 8, 9, 10, and 11 is an ultrafine fiber yarn that is pulled out rearward during use and folded when not in use on the rear surface of a horizontally long flat transparent body. The filter is made of a transparent mask that is thin and flat when stored.

However, even in this configuration, when storing the pocket, the filter made of ultrafine fiber threads is only covered with the rear surface of the transparent body, and the filter part that is removed from the airtight member on the other side of the filter is the other part. Because it touches objects, there are some users who are hygienic to store in their pockets when they are not in use.

The present invention takes the following technical means in order to solve the above-mentioned problems. In the first aspect of the present invention, the left and right transparent plates (1), (2) and the front end edges (3) having substantially symmetrical planes are vertically integrated in the inner surface contact shape and faced to face each other. A filter (5) for purifying the air inhaled by the wearer is attached between the transparent plates (1), (2), the lower edge (4), (4) inwardly so as to be able to expand or close in the left-right direction. It was set as the structure of the mask with a transparent body.

Thus, when used, the left and right transparent plates (1) and (2) facing the front end edge (3) in the vertical direction are spread outwardly with fingers, and the filter for purifying air ( 5) expands at the same time. Further, when the left and right transparent plates (1) and (2) of the mask with a transparent body removed when not in use are closed in a substantially opposite flat plate shape, the filter (5) for purifying the air also becomes a flat left and right transparent plate (1). (2) It is folded in a narrow space, and the mask with a transparent body can be easily stored in the pocket as it is.

Next, in the invention described in claim 2, the filter (5) for purifying the air is interposed between the inner sides of the left and right transparent plates (1) and (2) via the front and rear folding edges (6) when stored. 2. The mask with a transparent body according to claim 1, wherein the mask is bent and does not protrude greatly outward from the peripheral edges of the left and right transparent plates (1) and (2).

With this configuration, the filter (5) for purifying the air does not protrude from the inner surfaces of the left and right transparent plates (1) and (2) when stored, so the left and right transparent plates closed in a plane-facing manner when holding the removed mask. (1) (2) can be picked from both outer surfaces and stored in the pocket as it is during storage. The filter (5) surface for purifying air is covered with the left and right transparent plates (1) and (2). Therefore, it is easy to prevent dust from adhering, and it can be reused with less resistance.

In the first aspect of the present invention, when a pair of planar left and right transparent plates (1) and (2) are spread left and right with fingers around the front edge (3), the lower edge (4 (4) The filter (5) for purifying the air integrally attached between the inner sides can also be used as a mask with a large triangular pyramid shape that is also expanded to the left and right, and the left and right transparent plates (1) ( When 2) is closed with fingers around the front edge (3), most of the filter (5) for purifying air is folded narrowly between the flat left and right transparent plates (1) and (2). Since it becomes thin, the mask with a transparent body can be easily stored in the pocket as it is.

In the invention of claim 2, the filter (5) for purifying air does not protrude from the inner surfaces of the left and right transparent plates (1) and (2) during closed storage. The plate (1) (2) is picked from the outer surface and stored in the pocket as it is for storage. The filter (5) surface for purifying the air is covered with the left and right transparent plates (1) and (2). Therefore, it can be easily reused without a sense of resistance.
Furthermore, if the number of the folding edges (6) in the front-rear direction is increased, the surface area of the filter (5) in use increases and the passage resistance decreases. The discharged air is easily guided and discharged downward along the inner surfaces of the left and right transparent plates (1) and (2).

First example, overall side view with filter closed 1 is a side view of the entire filter with the filter expanded. Overall rear view of FIG. Overall front view of FIG. Overall plan view of FIG. FIG. 3 is a perspective view. Second example, overall side view with filter closed The rear view of FIG. FIG. 7 is a plan view of the entire filter in an expanded state. Side view showing the mask wearing state Perspective view showing the mask wearing state

Embodiments of the present invention will be specifically described below with reference to the drawings. 1 to 6 show a first embodiment of the present invention.
The left and right transparent plates (1) and (2) each of the left and right transparent plates (1) and (2) are substantially symmetrical planes, and the front edges (3) of the left and right transparent plates (1) and (2) are straight in the vertical direction (curved shape is also acceptable) )), And the opposite inner surface side is integrated in the vertical direction so as to face the contact surface with a predetermined width.

In the illustrated example, a plurality of small holes (11), (11),... Are opened on the front edge (3) of each of the left and right transparent plates (1) and (2) at opposite vertical positions, and both small holes (11). (11) and the respective front end edges (3) and (3) covered with an elastic layer (12) in which an elastomer is fused on the inner and outer peripheral surfaces, and the front end edges of the left and right transparent plates (1) (2) ( The rear part is held in an elastic manner so that it can be expanded or closed around 3). The elastomer can have any color, not only transparent white (colorless) but also transparent, such as red, blue, and yellow, to opaque.

Although the front edge (3) protrudes forward from the straight line state of the example shown in the figure, with the curvature radius gradually decreasing as a curve, the space below the nose of the wearer becomes wide and wide in the width direction. However, when the rear portions of the left and right transparent plates (1) and (2) are expanded from the closed state, the expansion load acting on the elastomer also increases. In short, the radius of curvature may be reduced within the durability range of the elastomer.

The lower end edges (4) and (4) of the left and right transparent plates (1) and (2) are lower than the horizontal state in a side view. A filter (5) for purifying the air inhaled by the wearer is sandwiched between the lower end edges (4) and (4).
As shown in FIG. 3 and FIG. 5, the relationship between the three parties has a triangular pyramid-shaped pocket space toward the back and a fan shape that spreads backward in plan view.
And, from the upper end (8) of the left transparent plate (1) front end edge (3) to the rear end (9) of the left transparent plate (1) lower end edge (4), an arcuate curved edge portion (10) Tied. The right transparent plate (2) has the same symmetrical shape.

As shown in FIGS. 11 and 12, if the inner and outer surfaces of the peripheral edge of the curved edge (10) are covered with an elastic layer (12) fused with elastomer, the left and right transparent plates (1) and (2) When the part is used as a part of the mask, a gap is less likely to occur between the curved edge part (10) and the user's cheek. Although only a part of the configuration is shown in the curved edge portion (10), an attachment means such as a string, one end of a band for attaching the mask to the user's ear or head, or an adhesive tape is provided.

Between the lower end edges (4) and (4) of the left and right transparent plates (1) and (2), as shown in FIG. 3, the left and right sides of the filter (5) for purifying the air sucked by the user The side end mounting surfaces (7) and (7) are integrated by adhesion or welding.
In the illustrated example, the purification surface of the filter (5) extends in the left-right direction between the upper portions of the side end mounting surfaces (7), so it is left on the desk with the filter (5) surface expanded. However, the surface of the filter (5) is spaced apart upward, and is clean because the filter (5) does not directly touch pathogenic bacteria, dust or pollen that may be scattered on the desk. .

The filter (5) is a laminated non-woven fabric, and as shown in the plan view of FIG. 5, is a circle attached to the left and right transparent plates (1) and (2) so that the front edge (3) can be expanded or closed in the left-right direction. It is made into an arcuate edge, and when the left and right transparent plates (1) and (2) are closed, the folding edge (6) is folded at the center in the width direction and stored upward as shown in FIG. In the stored state, it becomes thin in the width (thickness) direction and can be easily stored in a pocket or a book.

FIG. 6 is a perspective view showing a state in which the left and right transparent plates (1) and (2) are expanded in the left-right direction. As the folded edge (6) of the filter (5) descends, the lower ends of the left and right transparent plates (1) and (2) of the transparent flat plate are kept open, and the upper end side of the curved portion (10) tends to be narrowed.
The user expands the left and right transparent plates (1) and (2), and covers the inner sides of the front edges (3) of the left and right transparent plates (1) and (2) along the nose bridge as shown in FIGS. Cover the cheeks with the curved edges (10) of the transparent plates (1) and (2), and attach the mask to the face via the wearing means.

At this time, elastomers can be made in any color with mixed pigments, from transparent white (colorless) to transparent, opaque such as red, blue, yellow, etc. When users are grouped by job system or occupation type, etc. If the elastic layer (12) group is formed by fusing the same color of elastomer over a plurality of masks, it is possible to identify from which the user belongs to which group or who is responsible. ) The facial expression of the mask wearer can also be heard through (2), giving a sense of security to others. Further, when the transparent elastomer is used, the user's facial expression can be clearly seen.

As shown in FIG. 10, since the mouth of the mask user can be seen through the left and right transparent plates (1) and (2), the eyes and mouth can be seen from others and the customer can be served with peace of mind even when wearing a hair cover.
Moreover, since exhaled air is discharged only downward along the inner surfaces of the left and right transparent plates (1) and (2), the other person can approach them with peace of mind.
In the explanation of the examples, as shown in the drawing, the shape of the material, such as a straight line or a curved line, is specified and explained in addition to the material name. is not.

Next, a second embodiment will be described. The difference from the first embodiment will be mainly described. In the side view of FIG. 7, the lower end edges (4) of the left and right transparent plates (1) and (2) extend substantially horizontally with respect to the front end edge (3). As this angle is made obtuse or sharp, the space around the nose and mouth changes slightly, but this angle takes into account the breathing resistance of the breath due to the filter area, the exhaust direction due to the guide surface, etc. It is determined and not limited to the horizontal direction.

Furthermore, in FIG. 8 and FIG. 9, the filter which is a laminated nonwoven fabric is a multi-area purification membrane (13) which is bent into a bellows with a constant width like a fan from the base to the open end. If the width on the base side is narrow and the width on the open end side is widened to be an inclined width, the absolute amount of the filter on the front end edge (3) side is reduced and the thickness in the width direction can be reduced.
Moreover, if the medicine which kills influenza virus is kneaded in the multi-area purification membrane (13), it will help to suppress the spread of infection.

Although the multi-area purification film (13) is thin, the thickness in the width direction increases because of the large number of superposed sheets. However, a small hole (11) is formed at the front end edge (3) of each of the left and right transparent plates (1) and (2) in the vertically opposed position. ) (11)... Are opened, and an elastomer is applied to one or both of the small holes (11), (11), the gap (14), and the front end edges (3), (3) of the inner and outer peripheral surfaces. Since it is covered with the fused elastic layer (12), there is no suction of outside air.

In the folded state, the thickness increases only in the vicinity of the lower edge (4) of the left and right transparent plates (1) and (2). However, when the pocket is inserted, it is stable if the thickness portion is placed on one side of the pocket so that a pencil can be inserted. Can be inserted and stored.
