Description

The present invention relates to masks.

Conventionally, a mask worn on the face includes a mask body that at least partially covers the wearer's face, and a pair of ear hooks that are respectively coupled to the mask body, that is, the mask body is held in its wearing position by the wearer. It is well known to have a pair of members that can be hung over each ear of the ear.

The ear hooks of the above masks are often string-shaped, but sheet-shaped ear hooks are also being considered in order to reduce the burden on the ears while wearing the mask and to obtain a comfortable wearing feeling. For example, in Japanese Unexamined Patent Application Publication No. 2002-100000, a pair of ear hooks are formed of a sheet-like ear hook sheet extending on the same plane in a state where both ear hooks are connected to each other by a connecting portion.

Japanese Patent No. 5762803

Since the sheet-shaped ear hooks as described above have a larger area than the string-shaped ear hooks, for example, in the mask packaging process, there are more chances of contact with the members of the device, and the members of the device It is easy to deform due to the force from the mask (easily displaced from the mask body). Such deformability can lead to inconvenience in the packaging process. For example, when the packaging package is made of a resin film, it is likely to be drawn into the sealing processing portion of the device during the sealing process, and so-called jamming may occur. In addition, due to deformation, the edges of the ear hooks are prone to twisting or tearing, and such twisting or tearing can prevent the masks from being counted correctly by an automatic counting device or stored in the prescribed packaging bag. Sometimes it doesn't.

In view of the above, it is an object of one aspect of the present invention to prevent deformation of ear hook portions during a mask packaging process or the like.

A first aspect of the present invention comprises a mask body and a pair of sheet-like ear hooks, each of which is joined to a lateral end region of the outer surface of the mask body; At least one of the main portions of the pair of ear hook portions is detachably attached to the outer surface of the mask body.

The ear hooks of the mask according to this aspect are joined to the lateral end regions of the mask body and are to some extent fixed relative to the mask body. However, the portion of the ear hook that is not joined to the mask body, especially the main portion that extends laterally from the base joined to the mask body, is likely to deform when some force is applied (the mask body 10 It is easy to shift against). Therefore, for example, in a mask packaging process, when the mask is housed in a packaging package and the package is sealed, the ear hooking portion may be pulled into the sealing processing portion of the device, resulting in so-called jamming. In addition, since the ear hooks are easily deformed, the ear hooks may become twisted or distorted. If there is such a twist or tear, it may not be possible to count correctly with an automatic counting device, or when multiple masks are stacked and packaged, the thickness of the entire stacked mask will change and it will be stored in the packaging package. may not be In addition, twisting and tearing can reduce the comfortable wearing feeling of the ear hook portion during use.

On the other hand, according to the first aspect, since the ear hooks are fixed to the outer surface of the mask body, it is possible to prevent the ear hooks from slipping with respect to the mask body. Therefore, the ear hooking portion is less likely to be deformed during transportation or packaging of the mask, and even if it comes into contact with a member of the apparatus, it is less likely to be affected by such a member. Therefore, it is possible to prevent the ear hook from being caught in the sealing process, and to prevent the ear hook from twisting or tearing.

Moreover, the fastening is formed so as to be detachable, and can be released by the user's normal force. Therefore, in the preparation stage for wearing the mask, the attachment by the fastening portion can be released by the normal operation of deploying the ear hook portion laterally outward, and no special operation is required.

In the second aspect of the present invention, the pair of ear hooks form a single sheet, and the ear hooks can be separated from each other by weakening the boundary line between the ear hooks. is coupled to

According to the second aspect, since the ear hook portions are joined together to form a single sheet, the number of parts is reduced and the complexity of manufacturing is reduced.

In the third aspect of the present invention, the fastening portion for fastening is formed so as to overlap the boundary line.

According to the third aspect, since the fastening portion overlaps the boundary line between the ear hooks, when the ear hooks are separated from each other in the preparation stage for wearing the mask, the ear hooks can be removed at the same time as this separation. The attachment of the hanging part to the mask body can be released. Therefore, the time and effort required to release the fastening by the fastening portion is reduced, and work for preparing to wear the mask is facilitated.

In a fourth aspect of the present invention, the ear hook portions are separated from each other.

When the ear hooks are separated from each other according to the fourth aspect, there is no need to form a single sheet with a pair of ear hooks.

In a fifth aspect of the present invention, the mask body has an upper end region, a central region, and a lower end region each having a length of one-third of the longitudinal length of the mask body, and A main portion is joined to the central region.

According to the fifth aspect, since the ear hooks are fixed to the mask body in the central region in the vertical direction, the movement of the ear hooks as a whole can be suppressed, thereby preventing displacement in the plane direction with respect to the mask body. can be prevented more reliably.

In a sixth aspect of the present invention, the mask body has an upper end region, a central region, and a lower end region each having a length of one-third of the longitudinal length of the mask body, and A main portion is joined to at least the upper end region and the lower end region.

According to the sixth aspect, the ear hooks are secured to the mask body in the upper and lower end regions in the vertical direction, thereby preventing the ear hooks from breaking or tearing at the upper and lower sides. It can be suppressed well.

In a seventh aspect of the present invention, the main portions of the pair of ear hook portions are detachably attached to the outer surface.

According to the seventh aspect, each of the pair of ear hooks can be more reliably fixed to the mask body. Moreover, even with the configuration in which the ear hooks are separated from each other as in the fourth aspect, deformation of the ear hooks can be suppressed, and inconvenience in the mask packaging process can be prevented.

According to one aspect of the present invention, it is possible to prevent deformation of the ear hooks during a mask packaging process or the like.

FIG. 6 is a plan view of a mask according to another embodiment of the present invention, viewed from the outer surface side;

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, in each drawing, unless there is a particular description, the same reference numerals may be attached to the same or corresponding configurations, and the description thereof may be omitted.

(Basic configuration of mask)
The mask in this form may be a mask capable of covering the wearer's face, more specifically at least the nose and mouth of the wearer. The mask according to this embodiment can have the function of preventing foreign substances from reaching the face and preventing droplets generated from the wearer from scattering, and is also called a sanitary mask or a surgical mask. . This form is preferably used as a disposable mask, but may be used as a mask that can be used repeatedly by washing or the like.

FIG. 1 shows a plan view of the mask 1. As shown in FIG. FIG. 1 is a view of the mask 1 viewed from the outside, that is, the side exposed to the outside without facing the face when worn. Further, FIG. 2 shows a plan view of the mask viewed from the inside (face side). FIG. 3 shows a sectional view taken along line II of FIG.

As shown in FIG. 1, a mask 1 according to the present embodiment includes a mask body 10 that is placed in front of the wearer's face when worn and that can mainly cover the wearer's nose and mouth, and a mask body 10 that is connected to the mask body 10. A pair of ear hooks 20, 20 is provided. The mask body 10 has a vertical direction (first direction) D1 corresponding to the vertical direction of the wearer's face when worn, and a direction perpendicular to the vertical direction (first direction) D1. and a lateral direction (second direction) D2, which is a direction corresponding to the direction. In the embodiment of FIG. 1, the mask body 10 has a rectangular plan view shape having long sides in the horizontal direction D2, but the plan view shape of the mask body 10 is not limited to that illustrated.

As shown in FIGS. 1 and 2, the mask body 10 has a pleat structure 15 formed by a plurality of folds (pleats) arranged side by side in the longitudinal direction D1. The folds of the pleated structure 15 can be formed by folding the sheet forming the mask body 10 multiple times along the folding lines along the lateral direction D2. The plurality of folds are fixed at the side portions (horizontal direction D2 end portions) of the mask body 10 . Therefore, when the mask 1 is used, the center portion of the pleat structure 15 in the horizontal direction D2 can be expanded in the vertical direction D1 so that the center of the mask body 10 in the horizontal direction D2 protrudes toward the outer surface of the mask 1. It can be curved and deformed into a shape that conforms to the three-dimensional shape of the face. A specific configuration of the pleat structure 15 is not particularly limited, and may be a known configuration formed on the mask body.

As shown in FIGS. 1 to 3, the pair of ear hooks 20, 20 are arranged on the outer surface of the mask body 10. As shown in FIGS. Each of the ear hooks 20 may have an annular shape (or a closed belt shape) in plan view, or the ear hooks 20 and the mask body 10 may form an annular shape. When worn, the wearer's ears are placed inside the ring of the ear hooking part 20 or inside the ring formed by the ear hooking part 20 and the mask body 10, that is, the opening 29, and the ear hooking part 20 is placed on the ear. can be hung on It is preferable that the pair of ear hooks 20, 20 be configured symmetrically when viewed in the drawing. Moreover, it is preferable that the mask 1 as a whole is also configured symmetrically.

The pair of ear hook portions 20, 20 in this embodiment are each formed in a sheet shape. As used herein, the term "sheet-like" or "sheet" refers to a shape whose length and width are greater than its thickness and which can be handled as a single member. Since the pair of ear hooks 20, 20 are sheet-like, when the ear hooks 20 are put on the ear when the mask is worn, the ear hooks 20 are attached to the earlobe, unlike string-like or thread-like ear hooks. The back surface can be touched face-to-face. Therefore, the burden on the ear and the peripheral portion of the ear can be reduced, discomfort and pain can be reduced, and a comfortable feeling of wearing can be obtained.

In the form shown in FIGS. 1-3, the pair of ear hooks 20, 20 are separably joined at the center in the lateral direction D2 to form a single sheet. The type of connection of this separable connection portion 28 is not particularly limited, but it is preferably a connection that can be separated by a user's normal force. The connection 28 may be formed as a perforation, for example with discontinuous cuts (FIG. 1). The connecting portion 28 can also be formed by reducing the thickness of the sheet or by making the boundary between the pair of ear hooking portions 20 weaker or more susceptible to stress by other means.

The pair of ear hooks 20, 20 may be configured to overlap at the center in the horizontal direction D2 without forming a single sheet, and may be detachably attached to each other at the overlapping portions. .

The mask body 10 may have a multi-layer structure in which a plurality of layers are laminated. For example, it may have a structure including at least three layers in which an intermediate layer having an enhanced function to trap foreign substances (dust, pollen, bacteria, viruses, etc.) is sandwiched between an outer layer and an inner layer. Each layer constituting the mask body 10 preferably includes a fiber-containing layer such as a nonwoven fabric, a woven fabric, or a knitted fabric, and more preferably includes a nonwoven fabric. Examples of nonwoven fabrics include spunbond nonwoven fabrics, spunlace nonwoven fabrics, meltblown nonwoven fabrics, air-through nonwoven fabrics, point-bond nonwoven fabrics, and the like. In addition, it is preferable to use a meltblown nonwoven fabric that can contain fine fibers for the intermediate layer. Moreover, the fibers constituting the fiber-containing layer are preferably resin fibers, and examples of resin types for the resin fibers include polyethylene, polypropylene, polyethylene terephthalate, and nylon. The basis weight of the outer and inner layers may be 15-50 g/m ² . The basis weight of the intermediate layer having high foreign matter trapping properties is preferably 10 to 100 g/m ² , more preferably 15 to 50 g/m ² .

The pair of ear hooks 20, 20 are coupled to both sides (both ends in the lateral direction D2) of the outer surface of the mask body 10, respectively. It is preferable that the ear hook portions 20, 20 have stretchability as a whole. As used herein, the term “stretchable” means that the length in the direction of pulling can be increased by pulling (applying tensile force), and stopping pulling (releasing tensile force) ) refers to having the property of being reversible or nearly reversible in length.

In the examples shown in FIGS. 1 to 3, each of the pair of ear hooks 20, 20 has an ear hook main body 21 and an extension member 22 arranged in the lateral direction D2 of the ear hook main body 21. you can The extension members (or auxiliary members) 22 , 22 may be sheet-like members extending along the longitudinal direction D<b>1 of the mask 1 . By forming the ear hooking part 20 by combining the ear hooking part main body 21 and the extension member 22, the shape, size, stretchability, etc. of the ear hooking part 20 can be flexibly changed, and various demands can be met.

The ear hook main bodies 21, 21 may be made of a material having elasticity at least in the lateral direction D2. For the ear hook main bodies 21, 21, for example, an elastic film stretched and surface materials are arranged on both sides and intermittently adhered can be used. Alternatively, in place of the stretchable film, a plurality of stretched rubber threads may be used that are spaced apart from each other. Also, the ear hook main bodies 21, 21 may be configured using stretchable nonwoven fabric, stretchable hot melt, or the like.

The extension member 22 is superimposed on the outer end portion of the ear hook main body 21 in the lateral direction D2 and joined at the inner joining portion 60 . Further, the extension member 22 is joined to an end region of the mask body 10 in the lateral direction D2 at an outer joining portion 50. As shown in FIG. In other words, the ear hook main body 21 is joined to the mask main body 10 via the extension member 22 .

Both the outer joints 50, 50 and the inner joints 60, 60 may be joined by joining means such as heat sealing, ultrasonic sealing, adhesives, sewing, or the like. In this embodiment, it is possible to select an optimum joint form for the outer joint 50 between the extension member 22 and the mask body 10 and for the inner joint 60 between the extension member 22 and the ear hook body 21 . The extension member 22 may have elasticity, but it is preferably smaller than the elasticity of the ear hook body 21 .

Also, the ear hooking portion 20 may be composed of a base portion 20b joined to an end region in the lateral direction D2 of the mask body 10, and a main portion 20m extending from the base portion 20b to the center in the lateral direction D2. The base portion 20b is a portion that is at least partially joined to the mask body 10, and in the example of FIGS. This is the part to do. On the other hand, the main portion 20m is a portion having a C-shape that opens outward in the lateral direction D2 of the mask 1 . The main portion 20m is opened outward in the lateral direction D2 when the mask 1 is used.

(How to use the mask)
A method of using the mask 1 of this embodiment shown in FIGS. 1 to 3 will be described below. When starting to use the mask 1 according to this embodiment, the user releases the separable joint 28 between the pair of ear hooks 20 before wearing the mask 1, and the ear hooks 20 , 20 from each other. More specifically, the user pinches or grips the pair of ear hooks 20, 20 with each hand and pulls them in opposite directions to release the connection of the connecting part 28. As shown in FIG. After that, the main portions 20m, 20m of the ear hook portions 20, 20 (in some cases, the portion consisting of the main portion 20m and the base portion 20b) are expanded outward (laterally) in the lateral direction D2. At this time, the user can open the pair of ear hook portions 20, 20 outward in the lateral direction D2 without changing the operation of separating and deploying them.

FIG. 4 shows a view after the pair of ear hooks 20, 20 of the mask 1 of FIG. 1 are laterally developed. 5 shows a cross-sectional view taken along the line II-II of FIG. As shown in FIGS. 4 and 5, when the pair of ear hooks 20, 20 are opened, the edges of the joints 50, 50 between the ear hooks 20, 20 and the mask body 10 in the lateral direction D2 are used as axes. , the ear hooking parts 20, 20 are turned inside out, and the surfaces of the ear hooking parts 20, 20 that have been facing the mask body 10 until then are exposed. In the illustrated form, the main portion 20m of the ear hook portion 20 and a part of the base portion 20b joined and integrated with the main portion 20m are turned inside out.

The pair of ear hooks 20, 20 may be arranged on the outer surface side or the inner surface side of the mask main body 10, but are arranged on the outer surface side of the mask 1 as shown in FIGS. preferably. If the pair of ear hooks 20, 20 are arranged on the outer surface side of the mask body 10, when the pair of ear hooks 20, 20 are released from each other and opened outward in the lateral direction D2, the mask body 10 It is possible to reduce or eliminate the possibility of touching the inner surface of the body, which is preferable from a hygienic point of view.

The mask 1 according to this embodiment can actually be used as follows. For example, in a state in which the mask 1 is placed with the outer surface of the mask body 10 facing up, the user holds the pair of ear hooks 20, 20 with their hands and opens them outward in the lateral direction D2. The mask 1 can be moved to the face of another person (wearer) while holding the ear hooks 20, 20 of the mask. After arranging the mask body 10 at a desired position on the other person's face, the pair of ear hooks 20, 20 can be hung on the other person's ears without changing the way of holding the mask. Therefore, the mask 1 according to the present embodiment can be suitably used when a person, such as a child or a sick person, who has difficulty in wearing a mask by himself/herself is made to wear the mask.

Furthermore, as shown in FIG. 1, the pair of ear hooks 20, 20 can be pinched by the user when the pair of ear hooks 20, 20 are separated from each other and opened outward in the lateral direction D2. Knobs 21t, 21t may be formed. The knob portions 21t, 21t are formed on the main portions 20m, 20m of the ear hook portions 20, 20, respectively. In addition, the knob portions 21t, 21t may be portions where the ear hook main bodies 21, 21 protrude from the edge of the mask main body 10, preferably from the lower end thereof in plan view. Since the knobs 21t, 21t protrude from the edge of the mask body 10, the user can use both hands without or almost without touching the mask body 10 itself, that is, neither the outer surface nor the inner surface of the mask body 10. The knob portions 21t, 21t can also be pinched with the . Then, the user can separate and unfold the pair of ear hooks 20, 20 without touching the mask body 10 or almost without touching it. Therefore, even in a situation where the user cannot give sufficient consideration to hand hygiene, the user can wear the mask 1 in good hygiene on himself or others. In addition, since the ear hooks 20, 20 have the knobs 21t, 21t, the user can hold the knobs 21t, 21t when or after putting the ear hooks 20, 20 on the ears of the wearer. The tension and position of the ear hooks can be easily adjusted. When the knob portion 21t protrudes from the edge of the mask body 10, the maximum length of the protruding portion in the vertical direction D1 is preferably 5 to 20 mm, more preferably 8 to 15 mm.

Furthermore, since the pair of ear hooks 20, 20 are connected to both sides of the outer surface of the mask body 10 instead of the inner surface (face-side surface) of the mask body 10, when the mask 1 is worn, that is, the ear hooks 20, When the mask 20 is opened to the sides and hung on the ear (FIGS. 4 and 5), both sides of the mask body 10 are pressed against the face by the ear hooks 20 from the outside. As a result, the gap between the mask body 10 and the face can be reduced on both sides of the mask body 10, and the functions of the mask, such as the function of blocking foreign matter and the function of preventing droplets emitted by the wearer from scattering, can be improved. . In addition, since the ear hooks 20 are not arranged on the inner surface side (face side) of both sides of the main body, the ear hooks 20 on both sides of the mask body 10 do not directly contact the wearer's face during wearing. Therefore, discomfort is also reduced.

Note that the mask body 10 may be formed with a mark 18 for distinguishing between the outer surface and the inner surface of the mask body 10 by embossing, printing, stitching, or the like. The form of the mark 18 is not limited as long as it can be visually recognized by the user. The marks 18 may be letters, numbers, symbols, graphics, logos, etc., as shown in FIG.

(fastening part)
As described above, the ear hooks 20, 20 respectively have bases 20b, 20b that are partially or wholly joined to end regions of the mask body 10 in the lateral direction D2, and from the bases 20b, 20b in the lateral direction D2. It consists of main parts 20m, 20m extending toward the center. The main portions 20m, 20m are main portions of the portions that are expanded (turned over) outward in the width direction D2 when the ear hook portions 20, 20 are used (FIG. 4, etc.). It can be said that the ear hooks 20 , 20 are fixed to the mask body 10 to some extent by joining the bases 20 b , 20 b to the mask body 10 . However, since the parts that are not joined to the mask body 10, particularly the main parts 20m and 20m, can move with respect to the mask body 10, during the packaging process of the mask 1, the parts of the equipment such as the conveying device and the packaging device Easily deformed when subjected to force. Here, the deformation of the ear hooks 20, 20 mainly means that the ear hooks 20, 20 (especially the central portion in the lateral direction D2) are displaced from the mask main body 10 in the plane direction. Although the degree of such deformation is not so large, the easy deformation of the ear hooks 20, 20 may cause inconvenience in the mask packaging process. For example, when the packaging package is made of a resin film, a film sealing process is required. In the sealing process, when the ear hooks 20, 20 come into contact with the sealing processed member, they are likely to be drawn in, resulting in so-called jamming. It may occur. Further, if the deformation (displacement) is likely to occur, the edges of the ear hooks 20, 20 are likely to be twisted or hollowed. Therefore, for example, when a plurality of manufactured masks are laminated, there is a possibility that the thickness of the entire laminated body obtained will be too thick to be accommodated in the desired packaging package, and the device may not be correct when counting the masks with an automatic counting device. may not be countable. Furthermore, if the edges of the ear hooks 20, 20 are twisted or dented, the wearing comfort of the ear hooks 20, 20 may be impaired when the mask is worn.

In contrast, according to the present embodiment, the ear hook portions 20, 20, more specifically the main portions 20m, 20 m of the ear hook portions 20, 20 are detachably attached to the outer surface of the mask body 10. there is The fastening portion 8 (FIG. 1) that forms the fastening can be formed by heat fusion, ultrasonic fusion, adhesive, sewing using an easily breakable thread, or the like. Of these, it is preferable to use thermal fusion bonding or ultrasonic fusion bonding because the fastening process can be performed after the ear hook portions 20, 20 and the mask body 10 are superimposed, and the fastening portion 8 can be positioned more easily. .

Since the ear hooking portions 20, 20 are secured to the outer surface of the mask body 10 by the fastening portion 8 before use, the ear hooking portions 20, 20 are attached to the mask 1 during the packaging process of the mask 1. When the ear hooks 20, 20 come into contact with the member, even if the ear hooks 20, 20 are pulled to some extent, the ear hooks 20, 20 are not largely displaced with respect to the mask body 10.例文帳に追加Therefore, the stability of the form (shape) of the mask 1 as a whole is maintained, and inconveniences (occurrence of biting, twisting, or curling) occurring in the packaging process can be prevented.

The fastening portion 8 may be formed at one location as shown in FIG. 1, or may be formed scattered at a plurality of locations as described later. Also, the fastening portion 8 formed at one location may be formed so as to occupy a continuous predetermined area, or may be formed by an assembly of a plurality of small fastening portions slightly spaced apart from each other. The top view shape of one fixing portion 8 may be a circular shape as shown in FIG. 1, other shapes, or a linear shape (described later). Also, the total area of the fastening portions 8 provided on the mask 1 may be 1 to 50 mm ² . Since the ear hooks 20, 20 are secured to the mask body 10 by the fastening portion 8 having the total area within the above range, the ear hooks 20, 20 are reliably prevented from slipping from the mask body 10. In addition, the area of the fastening portion 8 becomes excessively large, making it difficult to separate the ear hook portions 20 from the mask main body 10 when using the mask 1, making it difficult to expand outward in the lateral direction D2. can be prevented.

The mask 1 may have, viewed in the longitudinal direction D1, an upper edge region E1, a lower edge region E2 and a central region C arranged therebetween. Each of these upper end region E1, central region C and lower end region E2 has a length of one third of the length of the mask 1 in the longitudinal direction D1. In the example of FIG. 1, the fastening portion 8 is formed in the central region C. As shown in FIG. Since the ear hooks 20, 20 are fixed to the mask body 10 in the central region C, the movement of the entire ear hooks 20, 20 in the planar direction can be more effectively suppressed.

Moreover, it is preferable that the fastening portion 8 is formed in the center in the lateral direction D2. That is, as shown in FIG. 1, the fastening portion 8 is formed on the boundary line between the ear hook portions 20, 20, or formed on the separable connecting portion 28 between the ear hook portions 20, 20. preferably. This arrangement also makes it possible to more effectively suppress the movement of the entire ear hooks 20, 20 in the planar direction. Furthermore, the fastening portion 8 is formed so as to include the centroid of the outer shape of the mask in plan view (in this example, the intersection of a straight line passing through the center in the vertical direction D1 and a straight line passing through the center in the horizontal direction D2). It is preferable to have a high effect of suppressing the movement of the ear hooks 20 , 20 .

As shown in FIG. 1, when the fastening portion 8 is formed on the separable connecting portion 28, when the ear hook portions 20, 20 are separated from each other at the stage of preparing to wear the mask 1, At the same time as this separation operation, the fastening of the fastening portion 8 can be released. Therefore, it is not necessary to perform separate actions for releasing the fixing by the fixing part 8 and separating the ear hook parts 20, 20, and the work for preparing to wear the mask 1 becomes easier.

(Modified example of fastening part)
6 to 9 show modifications of the fastening portion 8. FIG. In the mask 1A shown in FIG. 6, the fastening portion 8 is formed only on one of the pair of ear hook portions 20,20. In this manner, the fastening portion 8 may be formed so as to fasten at least one of the pair of ear hook portions 20 , 20 to the outer surface of the mask body 10 . As shown in FIG. 6, in an example in which the fastening portion 8 is formed so as not to include the connecting portion 28, the type of the fastening portion 8 can be freely selected without affecting the connecting portion 28. It is preferable from the point of view.

A mask 1B shown in FIG. 7 is formed with a plurality of fastening portions 8a and 8b (collectively referred to as fastening portions 8). In this example, a pair of ear hooking portions 20, 20 are secured to the mask body 10 by the securing portions 8a, 8b, respectively. Therefore, the deformation of each of the ear hooking portions 20, 20 is suppressed, and the inconvenience in the packaging process as described above can be more reliably prevented. When each of the pair of ear hooks 20, 20 is joined to the mask main body 10 as in this example, the configuration of the fastening portion that fastens each ear hook 20 (size of the fastening portion, (shape, formation position, attachment type, etc.) can be symmetrical with respect to the center line extending in the vertical direction D1 passing through the center of the horizontal direction D2, but it does not necessarily have to be line symmetrical.

Moreover, as shown in FIG. 8, the fastening portion may be formed in a place other than the central region C. As shown in FIG. In the mask 1C shown in FIG. 8, in addition to the fastening portions 8a and 8b (similar to FIG. 7), fastening portions 8c and 8d are provided in the upper end region E1, and fastening portions 8e and 8f are provided in the lower end region E2. is formed. Thus, when the fastening portion is formed in the upper end region E1 and/or the lower end region E2, twisting or curling of the edge portions of the ear hook portions 20, 20 can be effectively prevented. In this manner, the fastening portions can be formed scattered at different locations in the vertical direction D1.

In addition, the mask according to this embodiment can also have a form in which the fastening portions 8a and 8b in FIG. 8 are omitted. That is, it is also possible to adopt a form in which the fastening portion is formed in the upper end region E1 and/or the lower end region E2 and not formed in the central region C. In this case, the edge portions of the ear hook portions 20, 20 can be prevented from twisting or curling, as described above. In FIG. 9, as a modification of the mask 1C, fastening portions 8c and 8d are formed in the upper end region E1 and fastening portions 8e and 8f are formed in the lower end region E2. Here is an example that does not. In the case of this example, it is preferable that the ear hook portions 20 and 20 are connected to each other by the connecting portion 28 .

Further, FIG. 10 shows a mask 1D having linear fastening portions. In the example of FIG. 10, the fastening portions 8c and 8d in the upper end region E1, the fastening portions 8a and 8b in the central region C, and the fastening portions 8e and 8f in the lower end region E2 are all discontinuous linear. (dotted line). Such a dotted-line fastening portion can reliably join the ear hooking portion 20 to the mask main body 10, and even if the fastening portion is formed by heat sealing or the like, the surfaces of the mask main body 10 and the ear hooking portion 20 are not in contact with each other. It is preferable from the viewpoint that the portion to be denatured can be made small. In addition, when the fixing portion is formed in a linear shape, the line may be a dotted line as shown in the drawing or a solid line. The shape of the line may be a straight line or a combination of straight lines as in the fastening portions 8a to 8e in FIG. 10, or a curved line as in the fastening portion 8f. The fastening portion may be formed parallel to the vertical direction D1, or may be formed parallel to the horizontal direction D2 like the fastening portions 8a, 8c, and 8e. It may be obliquely formed as in 8d. Furthermore, a linear fastening portion may be provided in which a plurality of wires are arranged in parallel according to the thickness of the wire. The fastening portions formed in the upper end region E<b>1 and the lower end region E<b>2 may be formed linearly along the outline of the outer edge of the ear hooking portion 20 .

A mask 1E shown in FIG. 11 has ear hook portions 20, 20 separated from each other. In the case of such separated ear hooks 20, 20, the ear hooks 20, 20 do not need to be formed into a single sheet, so that the ear hooks 20, 20 can be designed more freely. Such separated ear hooks 20, 20 are preferably used, for example, when the length in the width direction D2 of the mask body 10 is desired to be increased, but the length in the width direction D2 of the ear hooks 20, 20 is desired to be reduced. Even in the case of the separated ear hook portions 20, 20, if the fastening portions 8a, 8b are formed in the ear hook portions 20, 20, respectively, the ear hook portions 20, 20 are separated. Since each of them is securely attached to the outer surface of the mask body 10, the ear hooking portions 20, 20 are prevented from being displaced, thereby preventing inconvenience in the packaging process.

In the examples shown in FIGS. 6 to 9 and 11, one fastening portion is formed in a circular shape. However, instead of the circular fasteners shown, other designs may be constructed with polygons such as ovals, triangles, squares, rectangles, rhombuses, hearts, stars, crescents, drops, or combinations thereof. You may provide the fixing part which has a shape which carries out. FIG. 12 shows another example of the shape of the fastening portion. The example shown in FIG. 12 is a modification of the fastening portion of the mask 1C shown in FIG. 8f is formed into a crescent shape. By changing the shape of the fastening portion in this way, the design of the mask is enhanced.

FIG. 13 shows a mask 101 according to another form. In the mask 101 shown in FIG. 13, the ear hooking portions 20, 20 are composed of the ear hooking portion main bodies 21, 21 without using extension members (auxiliary members) 22, 22. As shown in FIG. In this embodiment, the ear hook main bodies 21 , 21 are directly joined to the mask main body 10 at joints 150 . Joint 150 may be formed in a manner similar to outer joint 50 and inner joint 60 described above. Also in this embodiment, the fastening portion 8 similar to that shown in FIG. 1 can be used.
