Description

mask

The present invention relates to a mask.

As a configuration of the mask to be worn on the face, a mask body that covers at least a part of the wearer's face and a pair of ear materials (or ear hooks) coupled to the mask body, that is, the mask body is held in a predetermined position. Therefore, those equipped with a pair of members that can be hung on each ear of the wearer are known.

In recent years, various mask configurations have been studied from the viewpoint of ease of handling in manufacturing, in addition to the viewpoint of improving the function of the mask and improving the wearing feeling. For example, Patent Document 1 is a mask including a mask main body portion and an ear hook portion connected to the mask main body portion, and the ear hook portions are joined to each of both end regions, and the mask is masked in a plan view of the mask. A mask is disclosed having a connection portion in which both ear hooks joined to both end regions of the main body are fitted within the outer shape of the main body, and the both ear hooks are connected to each other within the outer shape of the mask body. ..

When using the mask disclosed in Patent Document 1, it is necessary to separate the two ear hooks connected by the connecting portion from each other and open them sideways before wearing the mask, and the user usually uses the two ears. Grasp the hanging part with your left and right hands and pull it. Here, in order to grip the ear hook, it is necessary to insert a finger between the ear hook and the main body and lift the ear hook between the finger and another finger. For example, insert the thumb between the ear hook and the main body, place another finger on the ear hook, and lift the ear hook between the thumb and the other fingers. Therefore, it is difficult to perform the operation of separating the ear hook portion without touching the main body. Therefore, in situations where sufficient hygiene of the fingers cannot be maintained, the hygiene of the mask may be impaired when the ear hook (or ear material) of the mask is separated and opened laterally before wearing. be.

One aspect of the present invention in view of the above is to provide a mask that can be worn in good hygiene.

One aspect of the present invention is a mask including a mask body and a pair of ear materials bonded to the mask body, and the pair of ear materials are separably bonded to each other before the start of use. And, it is arranged on the outer surface side of the mask body, and each of the pair of ear materials is provided with a grip portion protruding from the edge of the mask body in a plan view, and the grip portion is picked and pulled at the start of use. As a result, the pair of ear materials are separated from each other.

According to one aspect of the present invention, it is possible to provide a mask that can be worn under good hygiene.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In each drawing, unless otherwise specified, the same or corresponding configurations may be designated by the same reference numerals and description thereof may be omitted. In addition, the drawings are schematic to help the understanding of the invention.

(Basic mask configuration)
The mask according to one embodiment of the present invention may be a mask capable of covering the wearer's face, more specifically, at least the wearer's nose and mouth. The mask according to this embodiment may have a function of preventing foreign matter from reaching the face and preventing droplets generated from the wearer from scattering, and is also called a sanitary mask or a surgical mask. .. The mask may be disposable or reusable by washing.

FIG. 1 shows a plan view of the mask 100 according to this embodiment. FIG. 1 is a view of the mask 100 viewed from the outside, that is, from the side exposed to the outside, which does not face the face when worn. Further, FIG. 2 shows a plan view of the mask as viewed from the inside (face side).

As shown in FIG. 1, the mask 100 according to the present embodiment is arranged in front of the wearer's face at the time of wearing, and is coupled to the mask body 10 which can mainly cover the nose and mouth of the wearer and the mask body 10. It includes a pair of

ear materials

20 and 20. The mask body 10 has a vertical direction D1 corresponding to the vertical direction of the wearer's face at the time of wearing, and a horizontal direction D2 orthogonal to the vertical direction D1. In the form of FIG. 1, the mask body 10 has a rectangular plan view shape having a long side in the lateral direction D2, but the plan view shape of the mask body 10 is not limited to that shown in the drawing.

As shown in FIGS. 1 and 2, the mask body 10 has a pleated structure 15 formed by a plurality of folds arranged side by side in the vertical direction D1. The folds of the pleated structure 15 are formed by folding the sheet constituting the main body 10 along a folding line along the lateral direction D2. Then, in a state where a plurality of folds are formed, the side portions (lateral D2 end portions) of the mask main body 10 are joined and fixed. Therefore, when the mask 100 is used, the folds of the pleated structure 15 are widened in the vertical direction D1 so that the center of the horizontal direction D2 is curved so as to protrude toward the outer surface side of the mask 100 so as to match the three-dimensional shape of the face. Can be transformed into a different shape. The specific configuration of the pleated structure 15 is not particularly limited, and may be a known configuration used as a mask body.

As shown in FIGS. 1 and 2, the pair of

ear materials

20 and 20 are arranged on the outer surface side of the main body 10. As shown in FIG. 1, each ear material 20 may have a ring shape (or a closed band shape) or a shape including a ring in a plan view. At the time of wearing, the ear material 20 can be hung on the ear so that the wearer's ear enters the inside of the ring of the ear material 20, that is, the opening 29 in the center of the ear material 20. In the examples shown in FIGS. 1 and 2, the ear material 20 is composed of a rectangular annular sheet as a whole. Since the ear material 20 is in the form of a sheet, when the ear material 20 is put on the ear at the time of wearing, the ear material 20 can be brought into contact with the back of the ear on the surface, so that discomfort and pain are reduced.

The pair of

ear materials

20 and 20 may be configured as continuous sheets that are separably connected to each other at the center of D2 in the lateral direction. The bonding form of the separable bonding portions 28 of the pair of

ear materials

20 and 20 is not particularly limited, but it is preferable that the bonding is separable by pulling with the normal force of the user. For example, it may be formed as a perforation as shown in FIG. Further, the joint portion 28 may be formed by reducing the thickness of the sheet or by using other means to weaken the boundary between the pair of

ear materials

20 and 20 or make it easy to apply stress. Further, the pair of

ear materials

20 and 20 may be formed independently, slightly overlapped at the center of D2 in the lateral direction, and separably bonded by an adhesive, a heat seal, or the like to form a bonded portion 28. good.

The mask body 10 may have a multilayer structure in which a plurality of layers are laminated. For example, the structure may include at least three layers in which an intermediate layer having an enhanced function of collecting foreign substances (dust, pollen, bacteria, viruses, etc.) is sandwiched between an outer layer and an inner layer. Each layer constituting the main body 10 preferably includes a fiber-containing layer such as a non-woven fabric, a woven fabric, or a knitted fabric, and more preferably contains a non-woven fabric. Examples of the non-woven fabric include spunbonded non-woven fabric, spunlaced non-woven fabric, meltblown non-woven fabric, air-through non-woven fabric, point-bonded non-woven fabric and the like. Further, it is preferable to use a meltblown nonwoven fabric containing fine fibers as the intermediate layer. The fiber constituting the fiber-containing layer is preferably a resin fiber, and examples of the resin type of the resin fiber include polyethylene, polypropylene, polyethylene terephthalate, and nylon. The basis weight of the outer layer and the inner layer may be 10 to 50 g / m ² , preferably 15 to 50 g / m ² . The basis weight of the intermediate layer having a high foreign matter collecting property may be 10 to 100 g / m ² , preferably 15 to 50 g / m ² .

The ear material 20 may be formed of a material having elasticity, preferably a material having higher elasticity than the main body 10. Further, the ear material 20 may have at least elasticity in the lateral direction D2, and may have elasticity in both the vertical direction D1 and the lateral direction D2. The elasticity in the vertical direction D1 and the elasticity in the horizontal direction D2 may be the same or different from each other. When the elasticity in the vertical direction D1 and the elasticity in the horizontal direction D2 are different, it is preferable that the elasticity in the horizontal direction D2 is higher than the elasticity in the vertical direction D1. The ear material 20 is hung on the wearer's ear at the time of wearing and is pulled mainly in the lateral direction D2. Therefore, by having elasticity at least in the lateral direction D2, the main body 10 can be better positioned and fixed to the front of the face, and the burden on the ears of the ear material 20 can be reduced.

The ear material 20 may include a fiber-containing sheet having elasticity and / or may include a film having elasticity or elasticity. Examples of the fiber-containing sheet include non-woven fabrics, woven fabrics, knitted fabrics, and the like, and among these, it is preferable to use non-woven fabrics because of their good touch and breathability. Examples of the non-woven fabric include air-through non-woven fabric, spunbond non-woven fabric, spunlace non-woven fabric, needle punch non-woven fabric, chemical bond non-woven fabric and the like. The fiber contained in the nonwoven fabric is preferably a resin fiber, and examples of the resin type of the resin fiber include polyethylene, polypropylene, polyethylene terephthalate, and nylon.

The ear material 20 may include the above-mentioned elastic fiber-containing sheet or elastic film in a single layer, or a plurality of the above-mentioned elastic fiber-containing sheets and / or elastic films are laminated. For example, it may be configured by laminating a fiber-containing sheet and an elastic film. Further, a fiber-containing sheet or film having elasticity may be formed in combination with a sheet having no elasticity. The stretchable fiber-containing sheet or film can be sandwiched between non-stretchable sheets in a stretched state and adhered. When the fiber-containing sheet has elasticity, the elasticity is expressed by the fiber-containing sheet containing elastic fibers, for example, the fiber material itself has elasticity or the fibers are crimped fibers. It's okay. Alternatively, elasticity may be exhibited by a predetermined physical structure, for example, by having irregularities on the surface. Further, the ear material 20 may be formed by sandwiching the thread-like rubber with a fiber-containing sheet having or not having elasticity. When the elasticity of the fiber-containing sheet is low or not, the fiber-containing sheet can be attached from both sides in a stretched state.

More specifically, as the ear material 20, a single-layer non-woven fabric such as a stretchable air-through non-woven fabric, a stretchable spunbond non-woven fabric, a stretchable spunlace non-woven fabric, a stretchable needle punch non-woven fabric, and a stretchable chemical bond non-woven fabric can be used. .. Further, a non-woven fabric having a plurality of layers such as spunbond / meltblown / spunbond can be used. Further, a laminated sheet such as a non-woven fabric / stretchable film, a non-woven fabric / stretchable film / non-woven fabric (for example, spunbond / stretchable film / spunbond, air-through / stretchable film / air-through, etc.) can be used. When the ear material 20 is formed from a plurality of layers, the layers may be bonded to each other with a stretchable or non-stretchable hot melt non-woven fabric (a non-woven fabric in which the fibers are softened or melted by heating and can be adhered to other members). The basis weight of the ear material 20 may be ^{20 to 150 g / m 2.} The thickness of the ear material 20 may be 100 to 3,000 μm.

The pair of

ear materials

20 and 20 are connected to the side portions (lateral D2 end portions) of the outer surface of the main body 10, respectively. That is, the outer portions of the pair of

ear materials

20 and 20 in the lateral direction D2 are joined to the main body 10, and the other parts are not joined to the main body 10. When starting to use the mask 100 according to this embodiment, before wearing the mask 100, the pair of

ear materials

20 and 20 are separated from each other by releasing the separable bonds (separation operation). The portions of the

ear materials

20 and 20 that are not joined to the main body 10 are opened laterally to the D2 side (also referred to as unfolding operation).

(Separation / deployment operation of ear material)
FIG. 3 shows a diagram showing a state in which the mask 100 shown in FIG. 1 is about to be used. Further, FIG. 4 shows a sectional view taken along line II of FIG. At the start of use, the user can pinch or grasp the pair of

ear materials

20 and 20 with their respective hands and pull them in opposite directions as shown in FIG. Thereby, first, the bond of the separable connecting portion 28 can be released. If the joint portion 28 is composed of perforations formed along the boundary line between the pair of

ear materials

20 and 20, the perforations are broken and both

ear materials

20 and 20 are placed along the boundary line. Can be separated. After that, the user can open the pair of

ear materials

20 and 20 outward in the lateral direction D2 in the directions shown by the arrows in FIGS. 3 and 4, while holding the pair of

ear materials

20 and 20, respectively.

FIG. 5 shows a state in which the pair of

ear materials

20 and 20 are opened outward from the lateral D2 from the state of FIG. Further, FIG. 6 shows a sectional view taken along line II-II of FIG. As shown in FIGS. 5 and 6, when the pair of

ear materials

20 and 20 are opened, the

ear materials

20 and 20 are turned inside out, that is, the

ear materials

20 and 20 face the main body 10 in the state before the start of use. The surface that was being used is exposed. The

ear materials

20 and 20 are mainly arranged outside the lateral direction D2 of the main body 10, and the entire outer surface of the main body 10 is exposed. Such an operation of separating and unfolding the ear material is performed in preparation for wearing the mask 100. That is, the user can wear the mask 100 by himself / herself or have another person wear it after the ear material is separated and unfolded into the state shown in FIGS. 5 and 6.

While wearing the mask 100, that is, when the

ear materials

20 and 20 are opened sideways and hung on the ears, the

ear materials

20 and 20 are pulled toward the wearer's ears. The joint portion of the

materials

20 and 20 with the main body 10 is pressed toward the wearer's face. Here, in the present embodiment, since the pair of

ear materials

20 and 20 are connected to both side portions of the outer surface of the main body 10, a part of the ear materials 20 is outside the both side portions of the main body 10 while the mask 100 is worn. (FIG. 6), that is, both sides of the main body 10 are placed between the ear material 20 and the wearer's face, so that both sides of the main body 10 are placed on the face by the ear material 20. It is held down toward you. As a result, the gap between the main body 10 and the face can be reduced on both sides of the mask main body 10, and the function of the mask, for example, the function of blocking foreign matter, the function of not scattering the droplets emitted by the wearer, and the like can be improved. Further, since the ear material 20 is not arranged on the inside (face side) of both side portions of the main body, the ear material 20 does not come into contact with the wearer's face on both side portions of the main body 10 during wearing, which is better. You can also get a feeling of wearing.

Further, the main body 10 may be formed with a mark 18 that enables distinction between the outer surface and the inner surface of the main body 10 by embossing, printing, sewing, or the like. The form of the mark 18 is not limited as long as it can be visually recognized by the user. As shown in FIG. 1, the mark 18 may be a character, a number, a symbol, a figure, a logo, or the like.

(Ear material and picking part)
The pair of

ear materials

20 and 20 are provided with

gripping portions

25 and 25 that can be picked by the user when the pair of

ear materials

20 and 20 are separated from each other and opened outward in the lateral direction D2. The

knobs

25 and 25 project from the edge of the main body 10 in a plan view, and the user performs the above-mentioned operation of separating the pair of

ear materials

20 and 20 from each other and deploying them laterally. It can be done by picking 25 and 25.

Since the gripping

portions

25, 25 project from the edge of the main body 10 in a plan view, the user can pinch or grip the pair of

ear materials

20, 20 at a position away from the main body 10. Thereby, the separation and / or deployment operation of the ear material can be performed without touching the main body 10, or the area where the user touches the main body 10 can be reduced. Therefore, the user can pick the picking

portions

25, 25 without touching or hardly touching the main body 10 in the preparatory stage before wearing the mask. Similarly, the pair of

ear materials

20 and 20 can be separated and deployed without touching or hardly touching the main body 10. Therefore, even in a situation where the user cannot give sufficient consideration to the hygiene of the fingers, the mask 100 in a good hygiene state can be prepared.

Further, since the ear material 20 has the picking

portions

25 and 25, the user can adjust the ear material 20 by holding the picking portions 25 and 2 when or after the ear material 20 is hung on the wearer's ear. It can be done easily. That is, the position of the ear material 20 may be adjusted by holding the

knobs

25 and 25 and the ear material 20 may be displaced relative to the ear in the circumferential direction, or the ear material 20 may be pulled toward the rear side. By loosening it, the tension of the ear material 20 can be adjusted.

Further, in the mask 100 according to this embodiment, the pair of

ear materials

20 and 20 are arranged on the outer surface side of the main body 10. That is, the picking

portions

25, 25 picked by the user are also arranged on the outer surface side of the main body 10. Depending on the situation in which the mask 100 is used and / or the movement of the user, the user's hand may touch the mask body 10 when pinching the gripping

portions

25, 25, but even so, the user The touch of the mask body 10 may be restricted to the outer surface of the mask body 10. As described above, according to this embodiment, the contact between the inner surface (the surface facing the wearer's face at the time of wearing) and the hand, for which hygiene is particularly desired to be maintained, can be eliminated or reduced. Even if the mask 100 is touched, the hygiene of the mask can be ensured.

FIG. 7 shows an enlarged plan view of one ear material 20 of the mask 100. As described above, the ear material 20 is provided with a grip portion 25 protruding from the edge of the main body 10 in a plan view. The size of the picking portion 25 and the like is not particularly limited as long as the user can pick it with his / her fingers. However, the maximum length a of the portion of the grip portion 25 protruding from the edge of the main body 10 in the vertical direction D1 is preferably 5 to 15 mm, more preferably 8 to 15 mm. In the example shown in FIG. 7, the length a is the length in the vertical direction D1 from the edge of the main body 10 to the apex 25s of the protruding portion of the grip portion 25. By setting the length a within the above range, it becomes easy for the user to pick the picking portion 25, the ear material 20 can be reliably lifted, and the

ear materials

20 and 20 can be easily separated from each other, and the mask 100 can be easily picked up. It does not interfere with the wearing, and it is possible to reduce the discomfort that the knob 25 may give by touching the face or ears even during wearing.

The protruding portion of the knob portion 25 that protrudes from the edge of the main body 10 in a plan view may have a convex shape in a direction away from the main body 10. In that case, the contour of the protruding portion of the knob portion 25 may be curved or linear. However, if the contour is curved, the angular portion is reduced, so that the grip portion 25 is difficult to break, and when handling the mask 100 (when separating and unfolding the

ear materials

20 and 20 and when wearing the mask 100). When a hand or face touches the edge of the knob 25, a feeling of strangeness is unlikely to occur.

When the contour of the protruding portion of the knob portion 25 is curved, the radius of curvature at the apex 25s of the protruding portion may be 5 to 20 mm. By having the radius of curvature in the above range, the shape of the gripped portion 25 becomes a shape that the user can easily pick up with a finger.

The position of the grip portion 25 is also not particularly limited, and the lateral D2 length from the edge of the mask 100 in the lateral direction D2 to the position where the grip portion 25 protrudes most (in the example of FIG. 7, the protrusion of the grip portion 25). The lateral D2 length) b up to the apex 25s of the portion is preferably 45 to 90% of the length c which is 1/2 of the lateral D2 length of the entire mask 100, and more preferably 65 to 80%. preferable. By setting the length b to 45% or more of the length c, the

ear materials

20 and 20 are too far from the separable joint portion 28, and the

ear materials

20 and 20 cannot be separated and deployed smoothly. To prevent. On the other hand, by setting the length b to 90% or less of the length c, when the left and

right knobs

25 and 25 are picked by both hands, both hands come too close to each other and interfere with each other. There is no.

It should be noted that the contour of the most protruding portion of the knob portion 25 does not have a vertex 25s and includes a portion parallel to the edge of the main body 10, that is, includes a portion where the distance from the edge of the main body 10 is constant. In some cases (forms shown in FIGS. 8 (a) and 9 described later, etc.). In that case, the length b is from the edge of the mask 100 in the lateral direction D2 to the center of the portion parallel to the edge of the main body 10 (the portion where the distance from the edge of the main body 10 is constant) in the lateral direction D2. Let it be the length.

The knob portion 25 may protrude from the lower end of the main body 10 or may protrude from the upper end in a plan view. Further, a knob portion protruding from the lower end of the main body 10 may be provided on the lower side of the ear material 20, and another grip portion protruding from the upper end of the main body 10 may be provided on the upper side of the ear material 20. However, as shown in FIG. 7, when the knob portion 25 protrudes from the lower end of the main body 10 in a plan view, the user can naturally separate and deploy the

ear materials

20 and 20. For example, when the user prepares to wear the mask 100, the mask 100 is placed in a horizontal plane in front of the user's body, its vertical direction D1 is in the vertical direction of the body and its lateral direction D2 is in the horizontal direction of the body. Can be placed along. Therefore, if the user naturally extends both hands toward the pinching

portions

25 and 25 of the

ear materials

20 and 20 with the back of the hand facing up, the user can pick up the thumb of the pinching portion without changing the shape (posture) of the hand. The picking

portions

25, 25 can be picked by arranging the other fingers on the lower side and above the picking portion (FIG. 3).

Furthermore, due to the structure of the human body, it is easy to move (open) both arms from the center of the front of the body to the sides. Therefore, the user picks the

grips

25 and 25 protruding from the lower end of the main body 10 as described above, and then pulls the

ear materials

20 and 20 in opposite directions to separate them and deploys them laterally D2. The operation to be performed can be easily performed. At that time, it is not necessary to change the picking method (change the shape or direction of the hand) from the state where the picked

portions

25, 25 are picked.

When the user grasps the

grips

25 and 25 of the pair of

ear materials

20 and 20 and opens them laterally to the outside of D2 as described above, for example, when the mask 100 is lifted, the outer surface of the mask 100 becomes the ear. The

materials

20 and 20 face the open user, and the inner surface (face side surface) of the mask 100 faces the side opposite to the user. Therefore, the mask 100 according to this embodiment is suitable for being worn by another wearer. That is, after the user opens the pair of

ear materials

20 and 20 outward in the lateral direction D2 (FIGS. 5 and 6), the mask 100 is attached to the other while holding the pair of

ear materials

20 and 20. After moving the mask body 10 to the wearer's face and arranging the mask body 10 at a desired position on the wearer's face, the pair of

ear materials

20 and 20 can be hung on the wearer's ears without changing the way the mask 100 is held. Can be done. Therefore, the mask 100 according to this embodiment can be suitably used when a person who has difficulty in wearing the mask by himself / herself, such as a child or a sick person, is to wear the mask.

As shown in FIG. 7, the ring of the ear material 20 has an adhesive portion 22 that is adhered to the mask body 10 and extends along the vertical direction D1, and a hook portion 24 that is arranged behind the ear when worn. It may have an upper transition portion 23 that migrates from the adhesive portion to the hook portion 24 on the upper side, and a lower transition portion 26 that transitions from the adhesive portion 22 to the hook portion 24 on the lower side. In the example shown in FIG. 7, the ear material 20 has a rectangular annular shape as described above, and more specifically, the adhesive portion 22 and the hook portion 24 extend along the vertical direction as a whole. The upper transition portion 23 and the lower transition portion 26 extend along the lateral direction as a whole. The knob portion 25 may be formed at the lower transition portion 26 or the connecting portion between the hook portion 24 and the lower transition portion 26.

(Modification example)
FIG. 8 shows a modified example of the knob portion 25. The shape of the grip portion 25 is particularly limited as long as it protrudes from the edge of the main body 10 and can be picked by the user, and if it is formed so as not to hinder the elongation of the ear material when worn. Not done. The knob 25 may have a shape such that the inclination of the tangent of the contour changes continuously as shown in FIG. 7, but as shown in FIG. 8A, the inclination of the tangent of the contour changes. The shape may include a portion that does not. More specifically, the shape may include a portion where the distance from the edge of the main body 10 is constant, or a shape including a substantially quadrangle. The ring of the ear material 20 has an adhesive portion 22 that is adhered to the mask body 10 and extends along the vertical direction D1, a hook portion 24 that is arranged behind the ear when worn, and a hook portion 24 from the adhesive portion on the upper side. It may have an upper transition portion 23 for transitioning to, and a lower transition portion 26 for transitioning from the adhesive portion 22 to the hook portion 24 on the lower side.

Further, as shown in FIG. 8B, the picking portion 25 may be provided with a highly rigid portion 25r having increased rigidity so that the user can easily pick it. The high-rigidity portion 25r can be formed by additionally applying a resin, embossing, attaching a highly rigid material, or the like. Further, as shown in FIG. 8C, the picking portion 25 may be provided with a mark 25c having a color different from the color of the ear material 20 so that the user can recognize the picking portion 25. The mark 25c may be formed by printing or may be formed by pasting a sheet having a small area.

Further, FIG. 9 shows a modified example of the pair of

ear materials

20 and 20. Also in the example shown in FIG. 9, similarly to the example shown in FIG. 17, the ring of the ear material 20 is adhered to the mask body 10, and the adhesive portion 22 extending along the vertical direction D1 and the ear when worn. It has a hook portion 24 arranged behind, an upper transition portion 23 that migrates from the adhesive portion to the hook portion 24 on the upper side, and a lower transition portion 26 that transitions from the adhesive portion 22 to the hook portion 24 on the lower side. It's okay. Further, the

knob portions

25 and 25 are provided in the lower transition portion 26. However, in the example shown in FIG. 9, the

knobs

25 and 25 are located from the center of the lateral D2 of the pair of ear materials 20 and 20 (or the center of the lateral D2 of the mask 100) as compared with the example shown in FIG. It is in a distant position. In other words, the knob 25 is located near the center of the lateral D2 of one ear member 20.

Further, in the example shown in FIG. 9, the shapes of the

ear materials

20 and 20 as a whole are also different from the examples shown in FIG. 1 and the like. Also in the example shown in FIG. 9, the ear materials 20 and 0 are each composed of an annular plan-shaped sheet having an opening 29. However, each ear material 20 is not a rectangular ring shape, but is rounded as compared with the example shown in FIG. 1 and the like. More specifically, the upper transition portion 23, the hook portion 24, and the lower transition portion 26 are all formed so as to have an arc shape. In the ear material 20 having a shape including such an arc, since the knob portion 25 is located near the center of the lateral direction D2 of the ear material 20, the rounded shape as a whole does not hinder the impression of a soft appearance.

As in the example shown in FIG. 9, from the viewpoint of improving the visual impression when the

ear materials

20 and 20 each have a more rounded shape, from the edge of the lateral D2 of the mask 100, The lateral D2 length to the position where the grip portion 25 protrudes most (in this example, the lateral D2 length to the center of the lateral D2 of the portion where the grip portion 25 protrudes most) b is the lateral direction of the entire mask 100. It is preferably 55 to 65% of the length c which is 1/2 of the D2 length.

(Auxiliary material)
In the mask 100 shown in FIGS. 1 and 2, the pair of

ear materials

20 and 20 are connected to both sides of the main body 10 via the

auxiliary materials

30 and 30, respectively.

Auxiliary materials

30 and 30 may not be provided.

FIG. 10 shows an enlarged view of a portion of the mask 100 where the auxiliary material 30 is provided. 10 (a) is a partial plan view, and FIG. 10 (b) is a sectional view taken along line III-III of FIG. 10 (a). Further, FIG. 11 shows a view after the ear material 20 is opened laterally D2 outward from the state shown in FIG. 10 (a) is a partial plan view, and FIG. 10 (b) is a sectional view taken along line IV-IV of FIG. 10 (a). In the examples of FIGS. 10 and 11, the main body 10, the ear material 20, and the auxiliary material 30 are arranged in this order. In FIGS. 10 and 11, the pleated structure 15 (FIG. 1 and the like) of the mask body 10 is not shown.

The auxiliary material 30 is provided to indirectly connect the main body 10 and the ear material 20 with the main body 10 and the ear material 20 interposed therebetween. More specifically, the main body 10 and the auxiliary material 30 are joined at the first joint portion B1, the ear material 20 and the auxiliary material 30 are joined at the second joint portion B2, and the main body 10 and the ear material 20 are joined. Is not directly joined to. The first joint portion B1 and the second joint portion B2 are, for example, means for joining the facing surfaces of the members by applying pressure and / or heat, for example, heat sealing, ultrasonic sealing, non-heating embossing, etc. Can be formed by. Of these, it is preferable to use a heat seal because reliable bonding is possible.

When the joint portion is formed by a heat seal or the like, the joint portion may include a plurality of welded portions. The welded portion may be continuous or discontinuous in the vertical direction D1 and / or the horizontal direction D2 at the joint portion. The shape of the welded portion of the joint portion is not particularly limited as long as the joint portion can sufficiently maintain its strength. The welded portion may be formed in a shape narrower than the length, that is, in a linear shape (straight line or curved line), or in a dot shape (shape that can be visually recognized as a point). More specifically, the plan view shape of the welded portion may be any shape such as a quadrangle such as a rectangle or a rhombus, a polygon other than the quadrangle, a circle, or an ellipse.

As described above, the main body 10 has a function of blocking the intrusion of foreign matter and preventing the scattering of droplets generated by the wearer, while the ear material 20 is placed on the wearer's ear when worn. It has a function of holding 10. Therefore, the main body 10 and the ear material 20 are usually made of different materials, and it is preferable that the ear material 20 is made of a material having relatively high elasticity. Therefore, in the conventional configuration in which the main body 10 and the ear material 20 are directly joined, when a force is applied to the mask 100 due to the ear material 20 being pulled or the like, the main body 10 cannot follow the elongation of the ear material 20. There is also the possibility that the joint cannot be maintained and the two will come off from each other.

On the other hand, in the present embodiment, the first joint portion B1 which is a joint portion between the main body 10 and the auxiliary material 30 and the second joint portion B2 which is a joint portion between the ear material 20 and the auxiliary material 30 can be formed separately. .. That is, by including the first joint portion B1 and the second joint portion B2, the force related to the coupling is dispersed, and the ear material 20 is less likely to come off. In addition, each joint can be formed in a form suitable for the characteristics of the two members to be directly bonded. Further, as the material of the auxiliary material 30, a material that can optimize both the bonding with the main body 10 and the bonding with the ear material 20 can be selected. As a result, the indirect bond between the main body 10 and the ear material 20 is less likely to break, and as a result, a mask that is less likely to break even when a force is applied can be obtained.

As described above, before wearing the mask 100 of this embodiment, the

ear materials

20 and 20 are separated from each other by picking and pulling the

grip portions

25 and 25 provided on the pair of

ear materials

20 and 20, respectively. , Open to each side. In such a separation / deployment operation of the

ear materials

20 and 20, a large force is likely to be applied to the mask 100. However, according to this embodiment, the

ear materials

20 and 20 are not easily peeled off from the main body 10 even in the separation / deployment operation at the start of use, and the wearing can be started in a good state.

The auxiliary material 30 may be formed of a non-stretchable or small material, or is preferably formed of a material having a certain degree of elasticity. Further, the auxiliary material 30 may be formed of a material whose shape can be irreversibly deformed when a force is applied. The auxiliary material 30 may also contain the same type of stretchable nonwoven fabric as the ear material 20, but the stretchability of the auxiliary material 30 is preferably at least lateral D2 and smaller than the stretchability of the ear material 20. .. Further, the elasticity of the auxiliary material 30 is preferably larger than the elasticity of the main body 10 at least in the lateral direction D2.

By providing the auxiliary material 30 having elasticity, even when the ear material 20 is pulled, the difference between the elongation of the main body 10 and the elongation of the auxiliary material 30, and the elongation of the ear material 20 and the elongation of the auxiliary material 30 The difference can be suppressed respectively. Therefore, both the first joint portion B1 between the main body 10 and the auxiliary material 30 and the second joint portion B2 between the ear material 20 and the auxiliary material 30 are less likely to break, and as a result, the indirect connection between the main body 10 and the ear material 20 Bonds are less likely to break. The basis weight of the auxiliary material 30 may be ^{5 to 100 g / m 2.} The thickness of the auxiliary material 30 may be 100 to 1,000 μm.

As shown in FIGS. 10 and 11, the auxiliary material 30 may be a sheet-like member extending along the vertical direction D1 of the mask 100. The length of the auxiliary material 30 in the vertical direction D1 is preferably the same as the length of the vertical direction D1 of the mask 100 (the length of the vertical direction D1 of the main body 10), but is shorter than the length of the vertical direction D1 of the mask 100. You may. Further, on one side (either left or right side) of the lateral direction D2 of the mask 100, the outer end 31 of the lateral direction D2 of the auxiliary material 30 is inward of the lateral direction D2 from the outer end 11 of the lateral direction D2 of the main body 10. It may be located on the outside or on the outside, but as shown in FIGS. 10A and 10B, it is preferably located at a position aligned with the outer end 11 of the main body 10 in the lateral direction D2.

The length (width) W of the auxiliary material 30 in the lateral direction D2 is preferably 15 to 35 mm, although it depends on the size and configuration of the entire mask 100 and the size, shape, and material of the main body 10 and the ear material 20. By setting the length of the lateral direction D2 within the above range, it is possible to sufficiently secure the areas of the first joint portion B1 and the second joint portion B2, respectively, while the auxiliary material 30 is used for the separation / deployment operation at the start of use and / Alternatively, it does not interfere with the wearing and does not interfere with the functions of the main body 10 and the ear material 20.

As shown in FIG. 10, the auxiliary material 30 is arranged on the outer surface side of the main body 10. Therefore, even while the mask 100 is being worn, the possibility that the auxiliary material 30 itself comes into contact with the wearer's face is low, and the good wearing feeling of the mask 100 of the present embodiment is not hindered.

Further, as described above, the ear material 20 in the present embodiment may function to press both sides of the main body 10 toward the wearer's face, but at least the auxiliary material 30 arranged on the outer surface side of the main body 10 is also at least. Partially, together with the ear material 20, it can perform the function of pressing the main body 10 toward the face. As a result, the gap between both sides of the main body 10 and the face can be further reduced, and the function of the mask 100 can be improved.

Hereinafter, specific embodiments of the present invention will be added.

(Appendix 1)
An aspect according to Appendix 1 is a mask including a mask body and a pair of ear materials bonded to the mask body, and the pair of ear materials are separably bonded to each other before the start of use. And, it is arranged on the outer surface side of the mask body, and each of the pair of ear materials is provided with a grip portion protruding from the edge of the mask body in a plan view, and the grip portion is picked and pulled at the start of use. As a result, the pair of ear materials are separated from each other.

In the embodiment according to the above appendix 1, a knob portion is provided in which a pair of ear materials protrude from the edge of the main body. Therefore, the user can pinch or grip the ear material at a position away from the main body. Thereby, the operation of separating the pair of ear materials from each other (separation operation), which is performed before wearing the mask, can be performed without touching or almost touching the main body. Further, the operation (deployment operation) of opening the separated ear material laterally (laterally outward) can be performed without touching or almost touching the main body. Therefore, the hygiene of the mask is not impaired in the preparatory stage before wearing the mask, and the wearer can wear the mask in which good hygiene is maintained.

When performing the above separation operation and deployment operation, the hand may touch the main body to some extent depending on the user's operation. On the other hand, in this embodiment, since the pair of ear materials are arranged on the outer surface side of the main body, even if the user's hand touches the main body, the hand touches the outer surface of the main body, and the hand touches the main body. The possibility of touching the inner surface is small. Since the inner surface of the mask (the surface facing the wearer's face when worn) is the surface for which hygiene is particularly desired to be maintained, at least by eliminating or reducing the contact between the inner surface and the hand, the hand in the separation operation and the unfolding operation. Can effectively maintain the hygiene of the mask even if it touches the body.

(Appendix 2)
In the aspect according to Appendix 2, the mask has a vertical direction corresponding to the vertical direction of the wearer's face and a horizontal direction orthogonal to the vertical direction, and the grip portion is under the pair of ear materials. It is provided on each side.

According to the aspect according to the above appendix 2, since the picking portion is provided on the lower side of the ear material, the user can pick the picking portion with a natural movement without difficulty. For example, the mask is placed on a table or the like so that its lateral direction is the left-right direction of the body and its upward and downward directions are along the front and rear directions of the body, respectively, and naturally toward the pinch portion of the ear material. If you extend both hands, you can put your thumb on the back side of the picking part (the inner side of the ear material or the side facing the main body) and the other fingers on the front side of the picking part (of the ear material) without changing the shape (posture) of the hand. The knob can be pinched by arranging it on the outer surface side).

(Appendix 3)
In the aspect according to Appendix 3, the lateral length from the lateral edge of the mask to the most protruding position from the edge of the mask body of the knob is the lateral length of the mask. It is 45 to 90% of 1/2.

According to the aspect according to the above appendix 3, the most protruding portion of the pinched portion of the ear material is at a predetermined position in the lateral direction with respect to the mask. Therefore, the left and right hands can pinch the pinch without hindering each other's movements, and when the ear materials are lifted and separated from each other and opened laterally, no large force or complicated movement is required. ..

(Appendix 4)
In the aspect according to Appendix 4, the maximum length of the knob portion in the vertical direction of the portion protruding from the edge of the mask body is 5 to 15 mm.

According to the aspect according to the above appendix 4, since the protruding portion of the picked portion has a predetermined length from the edge of the main body, a sufficient area can be secured for the user to pick the picked portion.

(Appendix 5)
In the embodiment according to Appendix 5, the knob has a curved contour.

According to the aspect according to the above appendix 5, the portion protruding from the main body is hard to break. In addition, it is possible to reduce the discomfort when the contour of the knob touches the hand during the separation / deployment operation before wearing, or when the ear material is hung on the ear at the time of wearing.

(Appendix 6)
In the embodiment according to Appendix 6, an auxiliary material arranged on the outer surface side of the mask body is further provided, and the pair of ear materials are respectively bonded to the side portions of the mask body via the auxiliary material.

According to the aspect according to the above appendix 6, since the pair of ear materials are respectively bonded to the main body via the auxiliary material, the mask can be configured without directly connecting the ear materials and the main body. Therefore, the joint portion between the main body and the auxiliary material and the joint portion between the ear material and the auxiliary material can be formed separately. That is, each joint can be formed separately in a format suitable for the material of the two members to be directly bonded. As a result, an indirect bond that is not easily broken can be formed between the ear material and the main body without impairing the function and wearing feeling of the member, and a firm and good wearing feeling can be obtained.
