Abstract

PROBLEM TO BE SOLVED: To provide an mask-auxiliary member that has a function of eliminating a gap between a mask and the nose or the face which occurs when a mask is worn, and that can prevent the gap correcting function from deteriorating even when a mask is repeatedly washed, and also to provide a mask which makes a mask insertion member (correcting member) attachable/detachable.SOLUTION: An mask-auxiliary member is composed of a resin member or a metallic member which at least has elasticity, and is provided with a structure to be mounted across the nose from outside a mask, on the parts of the nose and its periphery of the mask covering the mouth and the nose. The mask-auxiliary member has a function of correcting a mask mounted state for the purpose of closing a gap produced between the mask and the face, by pressurizing with a pressurizing member from both sides of the nose-covering part by the mask to the base of the nose (cheek). Alternatively, the mask is designed to have, in a specific region of the mask, a pocket or a fold-back part in which, for example, a freely deforming member (insertion member) is freely attachable/detachable.

Description

The present invention relates to a mask for wearing on a face to prevent suction of harmful particles such as pollen and bacteria.

Conventionally, masks have been used to prevent inhalation of pathogenic bacteria, pollen, dust, etc. into the body, and fine objects have been removed by the advancement of filter materials made of polymer fiber materials in addition to existing materials such as gauze. It can be shielded. However, there is a problem that the target fine particles directly enter the nasal cavity without passing through the filter due to a gap with the mask around the nose when the mask is worn despite the advancement of the filter performance.

As a countermeasure for this, as described in Patent Document 1, for example, a means is known in which a shape memory polymer is built in an upper part of a mask and is deformed along the nose when worn to reduce the gap. Further, Patent Document 2 describes that a U-shaped freely bendable edge material is fitted into the upper end of the mask so as to eliminate the gap between the mask and the face according to the shape of the nose. Yes. It is also known to use a freely deformable material (bending member) such as aluminum that is easily maintained in a bent shape, incorporated in the mask edge. Or the method of preventing the inflow of the fine substance from a clearance gap by arrange | positioning felt and foaming sponge in the site | part corresponded to a clearance gap is also known. Furthermore, according to Patent Document 3, there is also proposed a method of attaching a pressing member for pressing the nose portion from above the mask to the eyeglass pad (clings). Furthermore, Patent Document 4 proposes a technique for preventing spectacles from fogging by providing a folded portion at the upper end portion of the mask and using that portion as a non-breathable material. Further, Patent Document 5 discloses a thin resin tube for preventing deformation called a stake in the through hole of the ear string in order to prevent a gap generated between the mask and both cheeks due to the tension of the ear string when the mask is worn. There is a method for preventing deformation by being incorporated by a method such as sewing, when it is built-in or there is no hole in the ear strap. Further, Patent Document 6 describes a technique for preventing the generation of a gap by attaching a wire-filled vinyl tie to both the nose end portions and both cheek portions of a mask.

However, in such a method in which a deformable member or shape memory member is built in and fixed to such a mask, the shape memory member (free bending member) is damaged every time the mask is washed, and the correction function is lowered due to complicated deformation. Or the shape memory member breaks the mask, and it has been difficult to use it repeatedly. Therefore, a mask provided with such a correction member is a relatively expensive mask that has been molded with a three-dimensional structure mainly for medical use or a non-woven fabric in which an inexpensive free deformation member is incorporated in the nose. At present, it is widely used for disposable masks and the like. Furthermore, since many of the deformable members incorporated in the conventional mask are made of a relatively inexpensive material on the premise of disposable, and need to have a simple configuration, there are restrictions on the material and shape, and it is not always sufficient. The current situation is that the corrective function is not satisfied. Moreover, since the thing using the pad of spectacles presupposes wearing of spectacles, there exists a problem that the person who can use and the condition which can be used will be limited. Masks incorporating correction members are often used exclusively as disposable masks because they do not have resistance to washing. This is a reasonable form of use for applications such as medical services where the threat of infection is high, but it is acceptable in terms of price for daily use to prevent colds and prevent pollen suction. In reality, it is necessary to use an inexpensive and simple structure using a nonwoven fabric or the like.

However, for example, the size of influenza virus is about 0.08 microns to 0.12 microns, and a nonwoven fabric used for a normal mask can block only particles and droplets of about 3 microns or more, so it is said to be sufficiently effective. hard. Originally, in addition to these non-woven fabrics, in order to inactivate electrostatic filters, nanofilters with smaller openings (removes 0.03 microns or more), or filter materials or pollen with bactericidal properties A plurality of highly functional filter materials to which a decomposition catalyst or the like is added should be used in combination. However, considering the fact that they are disposable, it is not economically practical to use a high-priced material in combination. By the way, even with N95 standard filters used for medical purposes, it is actually possible to remove only particles of 0.3 microns or more, and the masking effect of the virus infection is not sufficient for the packaging of masks marketed using these filters. It is noted that. In addition, even if a mask using a high-performance filter of N99 standard that enables virus cutting is worn, many of the conventional masks that are premised on disposables are price restrictions and manufacturing restrictions as described above. Therefore, it was difficult to incorporate a correction member having a shape and elasticity having a sufficient correction effect. Therefore, there still remains a problem that if the gap between the face and the mask cannot be completely closed, a sufficient shielding effect cannot be expected even if the performance of the filter alone is improved.

As described above, the present invention has a function for eliminating a gap generated between the mask and the nose or face generated when the mask is worn, and the function of correcting the gap regardless of whether the mask is repeatedly washed or disposable. It is an object of the present invention to provide a mask auxiliary member, a mask, and an insertion member thereof that can prevent the deterioration for a long time.

Further, when an elastic member is used as the auxiliary member, it can be deformed in accordance with the undulation of the face or the movement of the mouth, and the generation of a gap can be effectively prevented. Furthermore, since it is not necessary to use an expensive shape memory member or mask incorporating a deformable member, it contributes to the effective use of resources in that it can be used for a long time without impairing the function.

Moreover, since it is not necessary to incorporate a shape memory member even for a disposable mask, there is no need to use a shape memory member, and there is an effect that it can be manufactured at a low cost simultaneously with resource saving. . Alternatively, as a result of the gap being effectively blocked, the effect of preventing fogging of the glasses is also exhibited.

Moreover, according to other embodiment, the mask which can prevent the damage at the time of washing can be provided by making the correction member into the removable mask structure. Further, it can be used as a reinforcing member for supplementing the gap correction function of a mask having a built-in correction member with low elasticity and insufficient gap correction function.

Further, in the mask having a structure in which the insertion member can be inserted and removed by providing a pocket in the mask, the mask and the insertion member (correction member) of the mask are separated so that only the mask body can be washed or replaced. It can be used, and the degree of freedom in selecting the insert material and designing the shape is increased.

In addition, it has been difficult to take out internal metal fittings and plastics with a mask having a correction member built in as in the past, and it has been difficult to separate when discarded. Since the present invention is detachable, it is also a great advantage that parts can be disposed of and separated and collected very easily.

According to the present invention, it is the latest mask filter material, an excellent filter material capable of capturing fine particles having an eye opening of about 0.1 microns that can be captured by influenza virus, and a filter material with enhanced antibacterial properties In addition to being able to be used in an inexpensive and simple manner, the choice of these high-functional materials and the degree of design freedom for masks can be greatly improved by making the correction member detachable. It is possible to provide an optimal gap correction means for maximizing the function of the functional material.

Embodiments of the present invention will be described below with reference to the accompanying drawings. In addition, this invention is not limited to the form of these drawings.

FIG. 1 is a perspective view of a mask auxiliary member according to the first embodiment of the present invention, and FIG. 2 is a front view thereof. FIG. 3 is a view of the mounting state seen obliquely from above. In FIG. 1, the mask auxiliary member 1 is formed of an arbitrary metal material such as aluminum, iron, stainless steel, or copper, or a resin-coated material such as polypropylene, polyamide, polyester, silicone, or polycarbonate, A mountain-shaped covering member 2 whose size and shape approximate to the nose, a presser portion 4 (pressing member) that gradually becomes thinner toward both ends and has flexibility and elasticity, and a coupling member 3 that is fixed to the mask. Formed from. Although the thickness of the covering member 2 varies depending on the material to be used, it is preferable that the covering member 2 is thin so as to be used without a sense of incongruity. When the above materials are used, the thickness is preferably about 0.1 to 2.0 mm. The same applies to the following embodiments, but regarding the size of the constituent members of the present invention such as the presser portion 4 and the covering member 2, the size of the nose and face are not only individual differences, but also adults and children. Considering that there are differences depending on races, it is preferable to prepare a plurality of sizes and shapes.

In addition, when the presser portion 4 is integrally formed with the covering member 2, it is set at about 0.05 mm at both ends. Further, when the presser member 4 is constituted by another member, for example, as shown in FIG. 14, from a film-like elastic member made of polyester, polyethylene, polyamide or the like having a thickness of about 0.03 to 0.3 mm. It is good also as a structure which adhered the holding member 23 which becomes this to the covering member 2. FIG. In this case, since the presser member 23 acts more elastically, a gap is hardly generated and the wearing feeling is also comfortable.

As shown in FIG. 2 (a), the mask auxiliary member 1 is attached by pinching the knob portion 5 having an anti-slip effect consisting of a convex portion or a groove portion, and pulling it in the direction of the arrow to open it. After pressing, when released as shown in FIG. 2B, the mask is mounted on the mask by pinching the nose of the mask with a force closing in the direction of the arrow. At this time, as shown in FIG. 3, the portion corresponding to the nose and cheek of the mask 6 is covered and the pressing member 4 is closed and pressed, so that the gap between the face and the mask is effectively closed. At the same time, since it has moderate elasticity, it has the effect of following the movement of the face and mouth and making it difficult to create a gap. This is a function that is far superior to that of a conventional member in which a deformable member having no elastically deformable portion is built in a mask. If the closing force of the covering member 2 is too strong compared to the tension of the earrings of the mask, the covering member 2 picks and closes only the mask fabric, resulting in a problem that a gap is created at the apex of the nose. For this reason, it is necessary to carefully determine the material, thickness, shape, and the like so that the minimum closing force necessary to close the gap works.

The tension of rubber in the market mask is not constant, so it may not be possible to fit one type. In such a case, since most of the tension of the mask is limited within a certain range, a plurality of types of mask auxiliary members 1 having covering members 2 having different closing forces so as to be able to cope with the tension within this range are provided. You may arrange. Alternatively, by attaching hooks such as the hook 17 in FIG. 9 or the hook 20 shown in FIG. 11 to both ends of the mask auxiliary member 1 and engaging with the ear strap, the mask fabric is pulled toward the center. You may make it prevent. This also contributes as a means for preventing the mask auxiliary member from falling, which will be described later.

Next, although the shape of the coupling member 3 is not limited to this, an example is shown in FIG. FIG. 4A is composed of a plurality of conical or needle-like projection groups 7 (including columnar fibers with no sharp tips), and exhibits a fixing action by entering between the fibers of the mask. is there. The length of the protrusions of the protrusion group 7 is such that it does not penetrate the mask, and it is preferable to give a curvature to the tip so as not to damage the face even if it touches the face when worn. As a material for the projection group 7, a soft resin such as polyethylene, polypropylene, polyester, and nylon (registered trademark) is preferably used to protect the skin and the mask fabric. Needless to say, it can be used. In addition, you may make it raise the coupling | bonding force at the time of mounting | wearing by making the standing direction of the projection group 7 perpendicular | vertical, or making it incline in the direction which the mask covering member 2 closes. Alternatively, by aligning the protrusions in random directions, the mask substrate may be effectively entangled and bonded.

As an example of another connecting member 3, FIG. 5B shows a case in which a fine resin fiber group 8 having a hook-like (fishhook-shaped) tip is joined by being entangled with a mask fiber. It is similar to what is known as one side (male side) of Kuraray trademark. As is well known, the magic tape is composed of a male member whose tip is a hook (fishhook) and a female member whose tip is a loop (ring). As a material, it can be molded from a resin such as polypropylene, polyester, or nylon. In this example, only the members corresponding to the males of the pair of magic tapes are originally used, but the present invention is not limited to this. A point to keep in mind when designing these coupling members 3 is that gauze is used on the outer part of many masks, and if the coupling force is too strong, so-called transmission is caused when the gauze is removed. It is important to select the projection group 7 and the entangled fiber group 8 having a thinness (softness) and shape so as to have a binding force that does not transmit the fabric.

Therefore, it will be understood that the shape of the projection group 7 and the fiber group 8 is not limited to this example, and should be functionally designed according to the above-described purpose. For example, since the above-mentioned Velcro tape has been well known for a long time, detailed description and illustration are omitted. However, by attaching the male member (hook shape) and the female member (loop shape) to each other, Peeling is performed. Either one of these male or female members is sewed on the mask or fixed with an adhesive or the like, and attached to or detached from the other connecting member attached to the auxiliary member. Damage can be avoided.

In addition, when using both sexes as a coupling member, it is preferable to attach a female fastener to the mask 6 side. The reason is that the male fastener is entangled with other fibers, so that the male fastener is not entangled with other laundry or damaged during washing. Velcro is widely used for clothing and the like, and its high washing durability is proved, so it is suitable as a coupling member used in the present invention.

FIG. 5 (c) shows an arbitrary end portion of the mask sandwiched by a clip 9 made of a resin having a spring property, a metal material, or a metal and a resin. It is the same as that used as the parts 12 and 22. As the spring material, known resin materials such as polyamide, polyarylate, polycarbonate, etc. can be used in addition to stainless steel and iron-based metal materials. In the figure, the contact surface with the mask is a flat surface, but in order to obtain a higher bonding force, the shape and material can be changed as necessary, for example, by providing appropriate unevenness or by making the end portion into a sawtooth shape.

In addition, although the simplest clip shape is described in FIG.4 (c), it is not restricted to this, For example, although it is frequently used for attachment parts, such as an employee ID card and a suspender of pants, it is pressure in an open state. May be used as the clip 9 so that the applied pressure is applied in the closed state, and there is an advantage that it can be easily attached to and detached from the mask and the risk of dropping off can be reduced.

In addition to this, the clip has a small spring property such as aluminum or copper, is easily deformable freely, and uses a material with plasticity (maintenance of the shape) as the clip material. It is good also as a method of making it fix. Further, as shown in FIG. 4 (d), the magnet pieces 9a and 9b may be bonded to the bent portion, so that any part of the mask 6 may be fixed by being sandwiched by the magnetic force of the magnet pieces. In this case, the bent portion (clip portion) needs to be a film-like material having sufficient flexibility to be deformed by a magnetic force, and is formed as a material different from the covering member. In the case where a magnetic member such as iron or stainless steel is used for the clip 9, it is not necessary to arrange two magnet pieces because the magnetic force acts only by providing one of the magnet pieces.

As for the coupling member 3, for example, when attaching with a coupling member having a relatively weak coupling force as shown in FIG. 4A, for example, it is easy to attach and detach, but there is a risk of dropping due to intense movement or impact. Furthermore, when the mask is removed from the face prior to the mask auxiliary member 1, there is a possibility of dropping. In this case, although illustration is omitted, even if the mask auxiliary member 1 is peeled off from the mask 6 by connecting the mask auxiliary member 1 and the ear strap of the mask with a hooked string or the like, It can be prevented from falling on a tabletop. It is preferable to appropriately take such measures against falling in other embodiments.

FIG. 5 shows another embodiment of the mask auxiliary member 10. The mask auxiliary member 10 has a thickness of 0.2 mm to 1 mm and a width of a metal plate made of iron, aluminum, stainless steel, copper alloy, or the like, which is coated with a resin such as silicone resin, polyimide, or polyamide. The plate-shaped presser member 11 of 3 mm to 30 mm is processed into a nose shape in advance or is formed into a flat plate shape by hand when wearing, that is, from the apex of the nose to the hems at both ends of the nose It is made up of a mounting portion 12 (clip) for mounting by deforming it into a shape that holds the periphery (cheek) and then hooking both ends to the string of the mask, or folding the ends and pinching them. . This attachment method is excellent in that it is not necessary to consider that the mask is drawn to the center by the closing force of the auxiliary member 1 as described in the first embodiment to cause wrinkles.

Further, as shown in FIG. 6, if the insertion pin 13 is inserted into the string passage hole of the mask and fixed as shown in FIG. This structure has the same effect of suppressing the gaps between the cheeks that occur on the cheeks that are pulled by the ear rubber straps, but the size of the mask is not constant. It is necessary to prepare multiple types according to the size. The insertion pin 13 is fixed by compressing and winding the pin 13 at the end of the mask pressing member as shown in the figure. By appropriately arranging another coupling member 3 as described in FIG. 4A or 4B on the mask side of these mask auxiliary members 10, it is possible to prevent misalignment and dropout during use. I can do it. In this case, the attachment part 12 and the insertion pin 13 are not necessarily required, and a simpler appearance can be achieved.

FIG. 7 shows a shape similar to that of the above-described embodiment, which is constituted by a net-like member 14, and a wire of about 0.05 to 1.5 mm made of iron, stainless steel, aluminum or the like is knitted to form a shape covering the mask. The mesh member 14 is formed so as to close the gap between the mask and the face by pressing around the nose. The advantage of this structure is that a freely deformable mesh material can be deformed into an arbitrary shape while having good air permeability and preventing stuffiness. Therefore, by not allowing the entire mask to be pressed but creating a gap in the periphery of the mouth, it is possible to prevent difficulty in breathing and hindering conversation due to wearing the mask member. In addition, resin coating can be applied to improve strength, decoration, and feel. In this example, the attachment hook 15 is for hooking on a mask string. Instead of this, it may be attached by the above-described fiber group 8 or attached by the clip 9.

Further, the mesh mask auxiliary member 14 shown in FIG. 7 does not need to cover the entire mask surface, and as shown in FIG. 11, it is a mask auxiliary member 19 having a mesh structure covering at least a region corresponding to both end portions of the nose. It is also possible to make it lighter. In the figure, reference numeral 20 denotes a hook for hanging on a mask string. Further, as shown in FIG. 12, the shape of the attachment hook portion can be made simpler by providing a round hole 21 at the end of the holding member 9 so as to pass the mask string. .

FIG. 8 shows the auxiliary member 1 of FIG. 1 further provided with a ventilation hole 16 in the covering member 2 and the pressing member 4. The purpose is to prevent dampness as in Example 3, and it is preferable to form a large number of vent holes within the range allowed by the mechanical strength. However, it is needless to say that when the glasses are used also for preventing fogging, it is preferable to have no vent holes. It goes without saying that vent holes can be provided as necessary in the structure of other embodiments of the present invention. Needless to say, the engineer can arbitrarily design the shape of the cover member 2 and the shape and thickness of the presser member 4 as long as the restraining member functions so as to fill the gap between the mask and the face. For example, as shown in FIG. 9, the width of the portion covering the central nose is increased, or although not shown, the width of the presser portion 4 on both side portions of the nose is increased, and the shape is arbitrary according to the function and fashion. I can do it. Reference numeral 17 denotes a hook for hanging on the ear strap of the mask.

In FIG. 10, a flexible member 18 made of an elastic resin film such as polyamide or polypropylene is bonded and fixed to a holding member 11 made of a metal material, so that the gap portion of the mask can be pressed more flexibly. Since the flexible member 18 is attached in a state of being inclined to the face side, the mask is pressed following the undulation of the face and the movement of the mouth, so that the gap correction effect becomes more reliable. Or you may make it press the clearance gap part of a mask elastically according to the undulation of a face by providing the elastic member 41 as shown in FIG. 25 mentioned later in the mask surface side of a pressing part.

FIG. 13 shows a clip 22 as a coupling member provided near both ends of the pressing member 11 of the mask auxiliary member 10. Here, the clip 22 is structured to attach the mask auxiliary member by sandwiching the upper end portion of the mask. If the clip 22 touches the cheek directly and feels uncomfortable, insert the cheek side of the clip 22 into the inner side of the base fabric layered on the mask without pinching the entire mask edge. A sense of incongruity can be reduced. Therefore, it is preferable that the clip 22 is made of a material that is as thin and soft as possible. Alternatively, for such a mask not having a multi-layer structure, by applying the resin coating such as silicone or urethane to the clip 22 as described above, the uncomfortable feeling can be reduced even if the skin is directly touched.

In the case where an elastic material is not used for the presser member 11, the effect of suppressing the generation of a gap by following the movement of the face and mouth as described in the first embodiment is insufficient. For this reason, in this example, an elastic member such as a sponge similar to the elastic member 41 as described later with reference to FIG. 25 is provided on the side where the restraining member 11 is in contact with the mask, thereby following the movement and undulation of the face. Is pressed elastically. Since this is described in Example 11, the drawing is omitted.

5, 6, 9, 10, 12, 13, 18, or FIG. 21, the contact surface side of the mask auxiliary member with the mask is shown in FIGS. 4 (a) and 4 (b). Needless to say, it is possible to prevent misalignment and dropout during use by providing the connecting member 3 having a structure other than the clip as shown in FIG. That is, the arrangement of the coupling members is not limited to one place, nor is the type or position limited. When the coupling member 3 having the structure shown in FIGS. 4A and 4B is used, the attachment portion 12 and the insertion pin shown in the modified examples of FIGS. 5, 6, 7, 9, and 12 are used. 13, it will be understood that the hook 15 and the hole 21 can be mounted without being necessarily provided. In other words, a desired number of coupling members can be used at desired sites.

Since the mask auxiliary member of the present invention is used repeatedly, it can be used hygienically for a long time by including a known antibacterial material in the coating resin. As an example, a resin or a paint in which silver ion material (Ag, Ag-Zn, Ag-Cu-based ion material) or silver fine particles are dispersed is well known. On the surface of these materials, it is known that many fungi such as viruses and bacteria are inhibited from growing and die over time. Such a mask auxiliary member of the present invention requires little cleaning, but if it becomes dirty, it should be removed from the mask and hand-washed or cleaned with little mechanical damage such as an ultrasonic cleaner. . When used in a medical institution or the like, it is preferable to use a cleaning agent containing a disinfectant or to reuse by performing ultraviolet sterilization or the like.

In the above embodiment, the auxiliary member is mainly for pressing the gap formed between both sides of the nose and the cheek. However, when the state when the conventional mask is worn is observed, as described in the explanation relating to FIG. In the vicinity of the region from the left and right cheeks to the ears due to the tension of the ear straps, the phenomenon that the both ends of the mask are attracted and lifted up in a dogleg shape is observed. Therefore, it can be seen that foreign matter such as pollen and bacteria may pass through the gap directly and be sucked. Therefore, in this embodiment, as shown in FIG. 15, the plate-like second mask auxiliary member 24 made of any of the materials of the above-described embodiments is attached to both ends of the mask by the coupling members 8 or the like, so that both cheek regions are This prevents the mask from lifting up. The attachment method is not limited to this, and a method of providing a clip as shown in FIG. The second mask auxiliary member 24 exhibits the maximum effect when used in combination with the mask auxiliary member 1 described above. However, the second mask auxiliary member 24 may be used alone depending on the state and application of the mask.

As another structure, for example, an upper part of the pin 13 as shown in FIG. 6 is omitted, but a drop-off prevention part such as a head of a nail larger than the string hole is provided, or a hook-like folding part is provided. By adopting a structure in which a pin-shaped rod-shaped member serving as a fall prevention part is inserted into the hole of the ear strap, the same gap correction effect and fall prevention effect are exhibited. However, for example, many disposable masks do not have ear string holes, so this method cannot be used. In this case, the coupling type auxiliary member described above is used.

Here, the mask auxiliary member may be integrally formed with the same material as a whole, or the cover member and the pressing member may be integrated with each other after being manufactured with different materials. The bonding portion may be integrated with the same resin, or any method of bonding different materials together. Further, in this example, the hook part is integrally formed. However, a hook part formed separately may be attached to the auxiliary member. In addition, since this mask auxiliary member is attached to the outside of the mask, it is possible to reduce the sense of incongruity and add fashionability by decorating with a pattern such as a preferred color or flower as necessary. Is possible. Since such painting and pattern printing methods are possible with existing technology, specific examples are omitted.

Further, for the mask material, for example, a similar mounting method can be applied to a so-called disposable mask or medical high-performance disposable mask using a nonwoven fabric or the like, and it is applied as an aid for gap correction. Therefore, a higher correction effect can be obtained. In hospitals where there is a high possibility that highly infectious pathogens exist, it is preferable to dispose of the mask. However, if a deformable member (correcting member) is attached to all masks as in the prior art, the cost increases accordingly. Therefore, even a disposable mask can be used as a utilization method with an enhanced preventive effect by using a mask auxiliary member as in the present invention in combination without attaching a correction member. In addition, unlike a fiber, an auxiliary member has the advantage that sterilization and disinfection are easy and it is easy to carry out antibacterial treatment. Even if the mask auxiliary member is required to be disposable, the present invention has a configuration that can be manufactured at a relatively low cost, so that it does not impose a heavy burden, and convenience is maintained. Furthermore, since the shielding effect can be further enhanced even if the auxiliary member of the present invention is further used from above the mask that already contains the correction member, the function as a reinforcing member for gap correction can be exhibited. Of course.

Next, the invention of a new mask capable of avoiding damage to the mask correction member by washing or the mask itself, which is a defect of the conventional mask, will be described. FIG. 16 is a perspective view of a novel mask 25 in the present invention. The mask 25 is provided with a belt-like pocket 26 that extends from the nose to the cheek when the mask is put on the face. FIG. 17 is a cross-sectional view of the mask 25 as viewed from above. The pocket 26 is provided with an opening 28, a material that can be freely deformed through the opening 28, has plasticity, and can maintain bending deformation. The insertion member 27 (which may be referred to as a correction member because of its function) can be inserted, arranged, or removed. Since this insertion member 27 can be freely inserted and removed, it can be removed during washing and only the mask 25 can be washed. The material of the pocket 26 may be the same as that of the mask base material. However, since gauze generally used is weak against friction, cotton fabric, polyester, or polyimide (nylon. It is preferable to use a cloth made of a chemical fiber such as

As the material of the freely deformable insertion member 27, iron and its alloys, aluminum and its alloys, metals such as stainless steel, and resins such as polyethylene are used. It is necessary to be. When a metal is used, a resin coating such as acrylic, silicone, polyethylene, or urethane may be applied if necessary to improve the tactile sensation and appearance. Further, the deformation characteristics and the restoration characteristics of both may be adjusted by superposing resin and metal.

FIG. 18A is a schematic view of the insertion member 27. In this example, a metal plate having a thickness of about 0.03 mm to 1 mm is formed into a strip or plate having a width of 2 to 6 mm and a length of about 50 mm to 120 mm. Acrylic, silicone or urethane coatings are applied to prevent oxidation and improve aesthetics. The size of the pocket 26 is slightly larger than the size of the insertion member 27, and the binding force is such that the insertion member does not fluctuate inside. You may add the fixing member for fixing an insertion member to others as needed. In FIG. 18B, an elastic film 27a made of polyester, polyimide, silicone, polyethylene or the like is further attached to both ends of the insertion member 27 by an adhesive or a caulking method. FIG. 19 shows a partial cross section in the vicinity of the nose in a corrected state in which the insertion member 27 is deformed so as to follow the shape of the nose by hand before or after the mask 25 of the present invention is attached to the face. By doing so, the gap can be effectively closed by the insertion member 27 that is arbitrarily deformed between the mask and the face. Furthermore, since the elastic film 27a flexibly presses the mask against the cheek, it is possible to follow the movement of the face and mouth and prevent a gap from being generated temporarily. Further, as can be seen from this structure, the insertion member 27 as the correction member is attached in a completely enclosed state, and therefore has a feature that there is little risk of dropping due to movement.

The thickness and size of the elastic film 27a may be any shape as long as it conforms to the size of the insertion member 27. FIG. 20 is a partial cross-sectional view showing a state in which the pocket 26 is built in a bag shape inside the mask. The pocket 26 is not visible from the outside, and there is an advantage that the aesthetic appearance is not impaired. In addition, although the opening part 28 is described as a space | gap in the figure, as well known, it is good also as a structure where the insertion member 27 does not fall out by overlapping the edge fabric which the opening part opposes. . Further, in this example, the pocket 26 is fixed to the mask, but separately from this, for example, an entangled member as shown in FIG. The pocket 26 may be configured to be detachable from the mask body. By adopting such a configuration, it is possible to correct a gap by attaching to a conventional mask not provided with a pocket.

In addition, this attachment / detachment is omitted in the drawing, but a structure in which the S pole and the N pole of the two magnets are arranged on the pocket and the mask side with the mask interposed therebetween so as to be fastened by magnetic force. When a thin plate made of a magnetic material such as iron or stainless steel is used as the correction member (insertion member) 27, it is adsorbed as it is, so that only one magnet may be provided on either one.

As described above, the mask 25 in which the insertion member 27, which is a free deformation member, is detachable is attached to the insertion member and deformed into a desired shape at the time of use, thereby correcting a harmful gap between the mask and the face. It can function as a member. Further, since the insertion member 27 is removed and washed during washing, damage to the mask 25 and the mask insertion member 27 can be avoided.

Therefore, it is possible to repeatedly use a mask using a higher performance filter material (for example, N99 standard nanofilter, electrostatic filter, or composite layer with antibacterial nonwoven fabric or gauze). The same problem can be solved at the same time. In addition, since it is not necessary to use a material that takes into account stress due to washing, the insertion member 27 should be selected in accordance with the purpose, such as a cheap material such as aluminum or iron, or a composite material such as stainless steel or high-performance plastic. I can do it. In the case of a mask using an electrostatic filter, it is known from the nature that the effect is reduced when a polar detergent is used, and washing with a neutral detergent is preferable. In the above description, it is assumed that the mask body is repeatedly used. However, as already described, the mask body can be made disposable as necessary, and only the mask auxiliary member can be repeatedly used. Nevertheless, the advantage of easy separation and collection is still available. As described above, it is a feature of the present invention that the usage method can be changed according to the purpose and the use environment, so that the degree of freedom in using the mask is increased.

FIG. 21 shows an example of the invention of the mask 25 having a further different structure. In FIG. 21A, the folded portion 29 is not limited to the shape above the mask 25, but is provided in a rectangular shape, for example. The folded portion 29 has a structure that can be folded along the dotted line in the figure. Further, a magic tape male tape 30 a is fixed to the folded portion 29, and a female tape 30 b is fixed to the main body side of the mask 25. The fixing method is preferably sewn, but an adhesive may be used. Next, in FIG. 21B, the insertion member 27 as the correction member described above or a correction member having equivalent deformation maintaining characteristics is placed at the position shown in the figure, and then, as shown in FIG. The insertion member 27 is fixed by folding back 29 and closing the male and female tapes. After that, like the method described above, the insertion member is arbitrarily deformed and used on the face.

Since the insertion member can be freely deformed, it is possible to correct the mask by correcting whenever an uncomfortable feeling or an unexpected gap occurs after mounting. Further, in the fixing method when the folded portion 29 is closed, it is possible to entangle and fix the fiber by attaching only one of 30a and 30b in FIG. 21 as a male fastener. In this case, as described in the first embodiment, it is necessary to select a projection group having an entanglement characteristic that does not damage the mask member.

Further, although not shown in the drawings, as described in the other embodiments, instead of the male and female tapes 30a and 30b, a magnet piece may be attached to at least one of them and closed by magnetic force. When a magnet is used only on one side, the folded portion can be closed by a magnetic force if a thin piece such as iron or magnetic stainless steel is used on the other side.

After use, after the folded portion 29 is opened and the insertion member 27 is removed, the male and female fasteners can be used repeatedly by washing in a closed state to prevent damage to the mask itself or other fibers. Also in this example, there is no problem even if the mask main body is disposable according to the situation of use. It will be understood that this embodiment is also suitable for preventing the insertion member from dropping due to movement.

Furthermore, as another configuration of this method, as shown in FIG. 24A, a mask 35 provided with a folded portion 36 different from the previous example is conceivable. A difference from the example of FIG. 21 is that a double folding region is formed as shown in FIG. FIG. 24B is a schematic view of FIG. 24A viewed from the side. Here, similarly to the case described with reference to FIG. 21, the insertion member 27 is simultaneously wrapped in the bent region, so that the insertion member 27 can be deformed into an arbitrary shape when the mask 35 is mounted, thereby preventing gaps. The insertion member 27 may be provided with a projection group 7 as shown in FIG. In this configuration, since the bent portion 36 is finally formed into a bag shape, the insertion member 27 is difficult to drop, and the fixing means for the bent portion 36 as described above is sufficient with a weak adhesive force. In a state where the insertion member 27 is deformed and attached to the face, a force to be closed by the force drawn by the ear strap 38 works, so that even if no fixing means is provided, the bent portion opens and the insertion member falls. There is nothing.

As a method for further strengthening the closing action, as shown in FIG. 24C, by attaching the ear strap 38 of the mask to the end of the first stage of the bent portion, the bent portion 36 is folded three times. When the mask 35 is attached to the face, as shown in the partial view of FIG. 24 (d), the ear strap 38 pulls the bent portion 36 from the outermost side, and the bent portion and the insertion member are folded inward. Since the end portion is closed by pressing down 27, the state where the bent portion is confined more reliably can be maintained. Note that the ear strap 38 may be attached by a known method such as an adhesive method in which a rubber band is passed through the string passing hole, but not provided with a string passing hole and thermally bonded to the end of the mask as shown in FIG. .

The dotted lines other than the folded portion 37 in the figure are perforated eyes in which a reinforcing member (correcting member) necessary for the mask end is sewn. As the reinforcing member (correcting member), a rod-like or linear member having a suitable elasticity such as polypropylene or polyethylene and a resistance to repeated bending of about 0.2 to 1.0 mm is used. Such a reinforcing member is built in a state where it can be inserted / removed through a hole provided at the end of the mask.

FIG. 22 shows an example of a mask auxiliary member using a spring material as a pressing force during mounting. In FIG. 22, the spring member 31 is formed of a coil spring and is closed inside when no load is applied. Support members 32 a and 32 b made of plastic or the like are integrally molded with the spring member 31 and attached to both ends of the spring member 31. A coupling member 3 similar to that described in the first embodiment is disposed inside the support member 32, and holding members 33a and 33b preferably made of an elastic material are provided at both ends of the coupling member 3 as shown in the figure. Is attached. The pressing member 33 can be basically the same as the pressing portion 4 described in the first embodiment. Further, the coupling member and the pressing member may be integrally formed by a mold or the like.

As shown in FIG. 23, the mask auxiliary member 33 spreads the spring by hand, covers the nose 34 and the mask not shown in the figure, and releases the hand to close the spring so that the coupling portions 3 a and 3 b It is fixed to the mask by being pressed by the mask. At the same time, the presser 33 is elastically deformed by the force pushed back by the mask and is deformed along the cheek. That is, it is necessary to select a spring strength of the spring member 31 and an elastic force of the presser member that have an acting force that does not cause discomfort during mounting. The basic configuration of this example is similar to that of the first embodiment, but is excellent in that it can be configured to be functionally superior while using a simple spring material. In this example, the shape of the spring is shown as a coil. However, the shape is not limited to this, and can be arbitrarily selected, such as a leaf spring. Moreover, as a material of a spring, plastics, metals, etc. can be selected suitably.

A mask auxiliary member 39 shown in FIG. 25A is a modification of the mask auxiliary member 10 shown in FIG. In FIG. 25, the point that the length of the clip 40, which is a coupling member, is formed long over both cheeks, and the point that an elastic member 41 made of sponge, felt, or the like is provided. As the sponge material, a known foamed material made of natural rubber, urethane rubber, EPDM (ethylene / propylene rubber) or the like is selected and used having a suitable cell diameter and elasticity.

The clip 40 has a coupling function for attaching the auxiliary member 39 to the mask and suppresses both ends of the mask, so that both side portions of the mask are deformed into a dogleg shape by the tension of the ear strap described above, and between the cheeks. It has a structure that also has a function of preventing the formation of a gap. Further, since the degree of compression of the elastic member 41 provided on the pressing portion side changes according to its elasticity and pressure, the gap between the undulation of the face and the mask can be effectively blocked. The elastic member 41 is tapered at both ends as shown in the figure to eliminate a step and prevent a gap with the mask. Therefore, regardless of this shape, various shapes can be formed according to the hardness (elasticity) of the sponge, such as an arc shape, a wedge shape, or a shape close to the gap shape between the nose and cheek. Note that there is no problem because some steps are eliminated by deformation of the elastic member 41 and deformation of the mask itself.

As described above, the elastic member 41 compresses and expands in response to the movement of the face and mouth, the attached state, or the change in the tension of the rubber band of the mask over time due to its elasticity. The effect which prevents it automatically is exhibited. Note that the buccal side of the clip 40 does not have to be the same length as the outside, and may be shorter than that shown in the figure as long as the length necessary for attachment to the mask is secured. Other configurations of the clip 40 can be the same as those described in the first embodiment.

Although not essential, the base of this mask auxiliary member 39 has a spring property and has a closed structure as shown in FIG. 25B when not attached to the mask. When it is spread out and pressed against the mask and released, it closes by its own spring force. By doing so, it can be attached by opening and closing as shown by the arrows in the figure and pressing the nose through the mask. In this example, since the mask auxiliary member 39 is attached and fixed by the clip 40, it is not always necessary, but the above-described coupling member 3 (projection group, entanglement member, etc.) is used in combination with other parts such as the peripheral part of the nose. By providing them, it is possible to more reliably prevent displacement and dropping during use.

Further, as is apparent from the principle, it is needless to say that the same effect can be obtained by using the flexible member 18 which is a film-like elastic member as shown in FIG. In this case, although not shown in the figure, the flexible member 18 can be more effectively followed by facial undulations and mouth movements by inclining or deflecting the cheek side, and the mask can be pressed toward the face side. The same effect as the member 41 is obtained.

As already described above, in this example, the mask auxiliary member 39 is not made of an elastic material, and a freely deformable shape maintaining (plastic) material such as iron or aluminum is used. It goes without saying that the same effect can be obtained by a method of mounting by deforming according to the shape.

Further, FIG. 25C shows a mask auxiliary member 39 obtained by molding an elastic plastic resin or a metal thin plate into a shape matching the shape of the periphery of the nose. In this example, the nose is not pinched by a spring force as shown in FIG. 25B, and the elastic member 41 disposed when the clip 40 is attached to the face with the upper end of the mask sandwiched, It is comprised so that the both base part vicinity of a nose may be pressed. By doing so, it is possible to effectively pressurize a necessary part, so that it is possible to design with a reduced feeling of pressure at the time of wearing. In addition, since the plastic or metal that is the base of the mask auxiliary member 39 has a thickness having an appropriate elasticity, an appropriate deformation occurs depending on the shape of the face and the strength of the ear straps when attached, and thus airtightness and This contributes to improving the wearing feeling. In addition, when it shape | molds previously with a type | mold in this way, it is necessary to prepare several shapes in consideration of the difference in the magnitude | size and shape of each person's nose as mentioned above. However, in this example, since the elastic member 41 can effectively absorb the difference in the shape and size of the nose, it can be adapted to most people with a minimum number of types (for example, about three types of sizes). I can do it.

In the drawings used in the present invention, the size and size relationship of each part of the component parts are not necessarily accurately drawn unless otherwise specified. However, the size and shape of these parts are determined by engineers in the field. The design can be changed as appropriate based on the gist of the present invention.

As described above, the present invention can be used as a mask for wearing on a face to prevent suction of fine particles such as pollen and bacteria, or an auxiliary member of the mask.
