In the following description, the same or corresponding elements are denoted by the same reference numerals, and overlapping descriptions are omitted. In the following description, the terms "upper" and "lower" are used based on the state when the user wears the shield and the non-woven fabric mask.

FIG. 1 is a perspective view showing how a shield 1 according to this embodiment is used. FIG. 2(a) is a front view showing a state before the shield 1 according to the present embodiment is attached to the nonwoven fabric mask 2. FIG. FIG. 2(b) is a front view showing a state in which the shield 1 according to this embodiment is attached to the non-woven fabric mask. As shown in FIGS. 1 and 2, the shield 1 is a member that is detachably attached to a non-woven fabric mask 2 for covering the user's mouth and nose and covers the user's eye area.

The non-woven fabric mask 2 is formed by a rectangular mask member, and may be composed of a single member or may be composed of a multi-layer member. A flexible metal insert (not shown) may also be provided along the edge 2a that spans the bridge of the nose. Rubber cords 3 are attached to both ends 2c, 2c in the width direction (long side direction) of the non-woven fabric mask 2 for hanging on the ears. The manner in which the non-woven fabric mask 2 is attached is not particularly limited, and it may not be a type that is hung on the ears, and may be a type that is tied with a string behind the head. A front surface 2d of the nonwoven fabric mask 2 is a surface to which the shield 1 is attached. At least the front surface 2d of the nonwoven fabric mask 2 is made of nonwoven fabric. However, a part of the mask member that constitutes the nonwoven fabric mask 2 may include a member other than the nonwoven fabric.

The shield 1 is a member that protects the eyes of the user wearing the nonwoven fabric mask 2 . The shield 1 is formed on the side of the lower edge 12 of the shield 1, overlapped with the nonwoven fabric mask 2, and formed on the side of the upper edge 11 of the shield 1, and an attachment portion E1 attached to the nonwoven fabric mask 2. and an eye protection part E2 capable of protecting the eyes of a person. The shield 1 is detachably attached while the attachment portion E1 on the side of the lower edge 12 is superimposed on the front surface 2d of the nonwoven fabric mask 2, and the nonwoven fabric mask 2 is attached to the human body. A connecting portion 20 that is detachably fixed to the nonwoven fabric mask 2 is formed in the attaching portion E1. The shield 1 is made of a transparent and flexible planar member. As a material for the shield 1, polyester, acrylic acid resin, polycarbonate, polystyrene, or the like is used. The polymer film from which the shield 1 is formed is 0.05 mm to 0.25 mm thick, most preferably 0.1 mm thick, to give the shield 1 the desired flexibility. The term "flexible" is used when the modulus of elasticity of the material from which the shield 1 is formed is from about 400 MPa to 7,000 MPa, preferably from about 1,200 MPa to 5,000 MPa, most preferably from about 1,350 MPa to 3,500 MPa. It means that there is

The shape of the shield 1 according to this embodiment will be described. However, the shape and size of the shield 1 according to the embodiment is merely an example, and any configuration can be used as long as it can be attached to the nonwoven fabric mask 2 and can protect the user's eyes. may be As shown in FIG. 2, the shield 1 has a lower edge 12 that is the edge of the side that is connected to the nonwoven mask 2 (that is, the lower side of the nonwoven mask 2 in use), and a side opposite to the lower edge 12. It has an upper edge 11 that is an edge (that is, an upper tip portion when the nonwoven fabric mask 2 is used) and both edges 13 that are edges in the width direction of the nonwoven fabric mask 2 . The upper edge portion 11 spreads along the width direction of the shield 1 so as to draw an arc projecting in the opposite direction to the lower edge portion 12 at a position spaced apart from the edge portion 2a of the nonwoven fabric mask 2 when attached. ing. The dimension L1 between the vertex 11a of the upper edge 11 (the point furthest from the edge 2a of the nonwoven mask 2) and the lower edge 12 is not particularly limited, but is set to 100 to 150 mm. The lower edge portion 12 of the shield 1 is formed with an extension portion 14 extending along the width direction, and a V-shaped notch portion 16 is formed at the center position in the width direction. That is, a notch 16 is formed in the lower edge 12 of the shield 1 at a position corresponding to the portion of the nonwoven fabric mask 2 that covers the nose. The depth L2 of the notch 16 is set to 10 to 25 mm, although not particularly limited. The angle α of the notch 16 is set to 45 to 135°, although not particularly limited. The extension portions 14 are formed on both sides in the width direction with the notch portion 16 at the central position interposed therebetween. In this embodiment, the extension part 14 extends outside the both ends 2c, 2c of the non-woven fabric mask 2 at the time of attachment. Both edge portions 13, 13 extend at an angle so as to widen toward the upper edge portion 11 side. The shield 1 is divided into a base portion 17 provided in a region near the central position in the width direction and at positions corresponding to the eyes of the user, and lateral portions 18 provided on both sides of the base portion 17 in the width direction. be. The lateral portion 18 is configured to extend toward the user's ear during use. The dimension L3 between the ends 18a, 18a of the lateral portion 18 in the width direction, that is, the total length of the shield 1 in the width direction is not particularly limited, but is set to 180 to 350 mm. In such a shield 1, at least a region closer to the lower edge portion 12 than the central position in the vertical direction is defined as the mounting portion E1. Further, an area closer to the upper edge portion 11 than the attachment portion E1 is defined as an eye protection portion E2.

The connecting portion 20 of the shield 1 will be described. The connection part 20 is for attaching the shield 1 to the nonwoven fabric mask 2 by connecting with the nonwoven fabric mask 2 . The connecting part 20 can be disconnected from the non-woven fabric mask 2 , and the disconnection allows the shield 1 to be removed from the non-woven mask 2 . Moreover, the connecting part 20 may be configured to be capable of being repeatedly connected to and released from the non-woven fabric mask 2 . In this case, the shield 1 can be attached and detached repeatedly with respect to the nonwoven fabric mask 2 . In addition, the shield 1 is attached to the nonwoven fabric mask 2 by the connection part 20 with a strength (connection strength) that allows the shield 1 to be detachably attached to the nonwoven fabric mask 2 while the nonwoven fabric mask 2 is attached to the human body. Fixed. Due to such connection strength, the shield 1 can be attached to the non-woven fabric mask 2 worn by the user via the connection part 20, and can be attached to the non-woven mask 2 while worn by the user. It becomes the structure which can be removed from the nonwoven fabric mask 2. FIG. The strength of the connection by the connection part 20 is set to such an extent that the shield 1 does not fall when the connection part 20 of the shield 1 is connected to the nonwoven fabric mask 2 while the user wears the nonwoven fabric mask 2 . The connection strength is preferably set to a strength that prevents the shield 1 from falling even when the user moves his or her head while the shield 1 is attached to the non-woven fabric mask 2 . Further, the connection strength is set to such a level that the shield 1 can be removed by pulling the shield 1 while the user is wearing the nonwoven fabric mask 2 without applying excessive force. In addition, the connection strength allows the nonwoven fabric mask 2 to be removed without causing excessive damage (for example, the nonwoven fabric mask 2 is torn, torn, or excessively fuzzed on the surface) when the shield 1 is removed. It may be set to a degree of intensity.

The connecting portion 20 is formed in the mounting portion E1 of the shield 1 . Further, the connecting portion 20 is formed on the back surface of the shield 1 (the surface facing the user's eyes when worn). The connecting portion 20 is configured by fixing a planar member connectable to the nonwoven fabric mask 2 to the back surface of the mounting portion E1 of the shield 1 . In this embodiment, the connecting portion 20 is formed to extend along the extending portion 14 of the lower edge portion 12 . The connecting portion 20 is configured to extend in a belt shape with a predetermined width. The width of the connecting portion 20 is set to about 90 to 110 mm, and the total length of the connecting portion 20 is about 180 to 220 mm (in this embodiment, the connecting portion 20 is divided into two by the notch 16, their total length). In this embodiment, the edge 20a on the lower side of the connecting portion 20 coincides with the extending portion 14 of the lower edge 12 of the shield 1, and the ends 20b, 20b of the connecting portion 20 are the edge 13 of the shield 1. , 13. With such a configuration, the connecting portions 20 are formed at positions corresponding to substantially the entire width direction of the non-woven fabric mask 2 , including positions corresponding to both end portions of the non-woven fabric mask 2 in the width direction.

When attaching the shield 1 to the non-woven fabric mask 2, the attaching portion E1 of the shield 1 is superimposed on the front surface 2d of the non-woven mask 2, and the connecting portion 20 is pressed against the front surface 2d of the non-woven mask 2 to connect them. In addition, the size of the mounting portion E1 (the amount of overlap of the shield 1 on the nonwoven mask 2), that is, where the connecting portion 20 is placed on the front surface 2d of the nonwoven mask 2 (how far away from the edge 2a of the nonwoven mask 2) Whether or not they are connected is not particularly limited as long as the eyes of the user can be sufficiently covered with the shield 1 . For example, the dimension L4 of the attachment portion E1, which is the area where the shield 1 is superimposed on the nonwoven fabric mask 2, may be set to approximately 15 to 50 mm (see FIG. 2(b)). However, the boundary line between the attachment portion E1 and the eye protection portion E2 need not be clearly defined on the product. At least a region of the connecting portion 20 closer to the lower edge portion 12 than the upper edge portion 20c may function as the mounting portion E1. A mark indicating the mounting portion E1 (that is, a mark indicating how much the shield 1 is superimposed on the nonwoven fabric mask 2) may be indicated on the shield 1. FIG. Moreover, part of the eye protection part E2 may be overlapped with the non-woven fabric mask 2 depending on how the user attaches it. The shield 1 is preferably arranged such that the center line in the width direction of the shield 1 and the center line in the width direction of the non-woven fabric mask 2 substantially coincide with each other. Moreover, the notch 16 is preferably arranged at a position corresponding to the portion covering the nose in the non-woven mask.

Any configuration can be adopted as the configuration of the connecting portion 20 as long as it can be connected to the front surface 2 d of the non-woven fabric mask 2 . Specifically, it is preferable that the connection strength of the connecting portion 20 to the nonwoven fabric mask 2 is 0.05 N or more. For example, as shown in FIG. 3( a ), the connecting portion 20 may be configured by mechanical engagement means 30 . Examples of the mechanical engaging means 30 include a surface fastener (mechanical fastener) and the like. The mechanical engaging means 30 has a structure in which a plurality of engaging elements (hooks) 31 are formed integrally with a base material 32, and each engaging element 31 is directly provided on the base material 32. . The back surface of the base material 32 of the mechanical engaging means 30 (the surface opposite to the surface on which the engaging elements 31 are formed) is fixed to the back surface 1b of the shield 1 with an adhesive, adhesive, or the like. The fixing strength of this portion is at least higher than the connection strength of the connecting portion 20 to the nonwoven fabric mask 2 . In addition, from the viewpoint of preventing the connection strength from becoming excessively high, suppressing damage to the non-woven fabric mask 2 during removal, and fixing the non-woven fabric mask 2 in a detachable manner, the mechanical engaging means should be considered. 30 preferably has a connection strength of 0.05 N or more to the non-woven fabric mask 2 . On the other hand, the upper limit of the connecting strength is not particularly limited, and mechanical engaging means 30 that can be normally used for nonwoven fabrics by those skilled in the art can generally be used. Note that, in a certain aspect, the upper limit of the connection strength may be 1.5N or less.

In addition, "connection strength" in the specification is a value measured as follows. First, the nonwoven fabric mask 2 and the shield 1 are overlapped so that the width direction of the nonwoven fabric mask 2 and the width direction of the shield 1 are parallel to each other. At this time, at least the connecting portion 20 is overlapped with the nonwoven mask 2 . Thereafter, a cylindrical roller having a mass of 1 kg and a smooth surface is reciprocated twice to connect the non-woven fabric mask 2 and the shield 1 . Next, with the non-woven fabric mask 2 fixed to the jig, the shield 1 is pinched by the clip of the tension tester, and the shield 1 is lifted in the direction of 90 degrees with respect to the non-woven fabric mask 2 at a speed of 300 mm/min. pull it off. The force required at this time is defined as "connection strength of the connecting portion to the non-woven fabric mask".

As shown in FIG. 3(a), the engaging element 31 of this embodiment includes a column portion 31a extending from a base material 32 and a head portion 31b formed at the tip of the column portion 31a. The shape of the engaging element 31 is not particularly limited, and may be appropriately set based on the dimensions (length, width) and extensibility of the mechanical engaging means 30 . For example, as shown in FIG. 5(a), the engaging element 31 may include a cylindrical post 31a and a hemispherical head 31b. The head 31b may be a disk having a plurality of grooves as shown in FIG. 5(b), or may be disk-shaped as shown in FIG. 5(c). . Alternatively, as shown in FIG. 6(a), the engaging element 31 may have a prism-shaped column portion 31a and an arrowhead-shaped head portion 31b. Further, as shown in FIG. 6B, the engaging element 31 may include a column portion 31a extending obliquely upward and a head portion 31b bending obliquely downward from the tip of the column portion 31a. Further, as shown in FIG. 6(c), the engaging element 31 includes a column portion 31a extending upward, and a head portion 31b extending from the upper end of the column portion 31a so as to curve in one direction in the lateral direction. It may be J-shaped as a whole. Further, as shown in FIG. 6(d), the engaging element 31 includes a column portion 31a extending upward and a head portion 31b extending from the upper end of the column portion 31a into two and curving in both lateral directions. and

The height of the engaging element 31 may be 0.25-0.75 mm, and may be 0.38-0.68 mm. Further, the density of the engaging elements 31 may be 900 to 2400/inch2, and may be 900 to 1600/inch2. The "height of the engaging element 31" indicates the distance from the surface of the base material 32 to the top (highest position) of the head 31b of the engaging element 31. For example, H in FIG. Dimensions shown. Within this range, it is possible to ensure an appropriate connection strength required for the connection portion 20 of the shield 1 regardless of the shape of the engaging element 31 . Also, when the user attaches the shield 1 while wearing the nonwoven fabric mask 2, the connection part 20 can be connected by lightly pressing the nonwoven mask 2 without excessively pressing it. In addition, even if the user shakes his or her head while the shield 1 is attached to the nonwoven fabric mask 2, the shield will not come off. In addition, when removing, the user can remove the shield 1 with a force that is enough to pull the shield 1 with one hand. In addition, it is possible to avoid leaving noticeable damage on the non-woven fabric mask when it is removed. If the connection strength is lower than the above numerical range, it becomes difficult to maintain the shield 1 attached to the non-woven fabric mask 2 . If the connection strength is higher than that obtained with the numerical ranges mentioned above, damage may be left on the non-woven mask 2 when the shield 1 is removed.

The material of the extensible mechanical engagement means 30 is a thermoplastic resin or the like, and examples thereof include a mixture of polypropylene resin (PP) and polyethylene resin (PE), and ethylene-vinyl acetate copolymer (EVA) resin. It is mentioned as. If a mixture of PP and PE is used, the PP and PE may be mixed in a weight ratio of about 95:5 to 30:70. If the amount of PP exceeds this upper limit, the properties of PP will dominate and the engaging elements will tend to be stiff. Conversely, if the amount of PP is below its lower limit, the engaging force of the engaging element will be weakened. PP may be either a homopolymer or a copolymer. Examples of PE include low density polyethylene (LDPE), high density polyethylene (HDPE), linear low density polyethylene (LLDPE), and the like.

Moreover, as shown in FIG.3(b), the connection part 20 may be comprised by the adhesive 40. Moreover, as shown in FIG. Specifically, the connecting part 20 may be constituted by a tape 41 provided with a layer of adhesive 40 . Tape 41 comprises a layer of adhesive 40 on substrate 42 . The back surface of the base material 42 of the tape 41 (the surface opposite to the layer of the adhesive 40 ) is fixed to the back surface 1 b of the shield 1 . The fixing strength of this portion is at least higher than the connection strength between the connecting portion 20 and the nonwoven fabric mask 2 . As the tape 41, for example, a double-sided tape may be adopted. The back surface of the base material 42 (the surface opposite to the surface on which the layer of the adhesive 40 is formed) is fixed to the back surface 1b of the shield 1 with an adhesive, an adhesive, or the like. The fixing strength of this portion is at least higher than the connection strength of the connecting portion 20 to the nonwoven fabric mask 2 . The adhesive 40 may have an adhesive strength of 0.05N or more to the non-woven mask 2, and may have a characteristic of 0.05 to 1.5N. As the adhesive 40, for example, an acrylic adhesive, a synthetic rubber adhesive, or a silicone adhesive is used. Within this range, it is possible to secure an appropriate connection strength required for the connection portion 20 of the shield 1 . Also, when the user attaches the shield 1 while wearing the nonwoven fabric mask 2, the connection part 20 can be connected by lightly pressing the nonwoven mask 2 without excessively pressing it. In addition, even if the user shakes his or her head while the shield 1 is attached to the nonwoven fabric mask 2, the shield will not come off. In addition, when removing, the user can remove the shield 1 with a force that is enough to pull the shield 1 with one hand. In addition, it is possible to avoid leaving noticeable damage on the non-woven fabric mask when it is removed. If the connection strength is lower than the above numerical range, it becomes difficult to maintain the shield 1 attached to the non-woven fabric mask 2 . If the connection strength is higher than that obtained with the numerical ranges mentioned above, damage may be left on the non-woven mask 2 when the shield 1 is removed.

Next, functions and effects of the shield 1 according to this embodiment will be described.

Here, conventionally, a mask with a shield, in which a shield is fixed to a mask by welding or the like, is known as a mask for protecting the eyes. Such shielded masks are used in medical settings such as hospitals. For example, a package consisting of multiple layers of shielded masks is installed in a hospital rack or the like, and the user removes the shielded mask from the package and puts it on when performing work to protect the eyes. do. However, in the medical field, in many cases, the user is already wearing a normal type mask, and it has been necessary to remove the normal type mask once to put on the mask with the shield. In addition, after finishing work that requires protection of the eyes, it was necessary to remove the entire mask with a shield and put on a normal type mask again. In addition, such a mask with a shield has a larger area than a normal mask, and there has been a demand for improvement in handling convenience.

On the other hand, according to the shield 1 according to the present embodiment, the connecting portion 20 that is detachably fixed to the nonwoven fabric mask 2 is formed in the mounting portion E1 on the side of the lower edge portion 12 of the shield 1 . As a result, when the mounting portion E1 of the shield 1 is superimposed on the front surface 2d of the non-woven fabric mask 2, the connecting portion 20 is detachably fixed to the front surface 2d of the non-woven mask 2, whereby the shield 1 is attached to the non-woven mask 2. be done. With such a configuration, the shield 1 can be attached without removing the non-woven fabric mask 2 from the face while the non-woven fabric mask 2 is attached to the user. Therefore, when the user performs work that requires protection of the eyes, the user can attach the shield to the non-woven mask 2 already worn. Only shield 1 needs to be removed. Also, the shield 1 can be handled as a member independent of the non-woven fabric mask 2 . Therefore, when a plurality of shields 1 are stacked and packaged, the package can be made more compact than a conventional shielded mask package.

In addition, since the shield 1 according to the present embodiment is a member independent of the non-woven fabric mask 2, for example, it is possible to store the shield 1 and discard only the non-woven mask 2, or only the shield 1 can be discarded. It is also possible to discard and continue to use the non-woven fabric mask 2 . Also, for example, when the shield and the mask are fixed with a clip or the like, it is necessary to prepare a clip as a separate member. No need to prepare separate parts. As described above, the convenience of handling the shield for protecting the eyes can be improved.

Moreover, in the shield 1 according to the present embodiment, the connection strength of the connecting portion 20 to the nonwoven fabric mask 2 may be 0.05 N or more. As a result, the shield 1 can be reliably attached to the nonwoven fabric mask 2 without the shield 1 being easily peeled off.

In the shield 1 according to this embodiment, the connecting portion 20 may be constituted by mechanical engaging means 30 having engaging elements 31 . In this case, since the connection strength is unlikely to decrease even after repeated use, the shield 1 can be used repeatedly while wearing the nonwoven fabric mask 2 . In addition, since the shield 1 can be easily removed from the non-woven fabric mask 2, it is easy to dispose and can provide safe eye protectors for medical workers. Then, the shields 1 can be placed on a rack or the like after being placed in a package by stacking the shields 1 without using a release paper unlike an adhesive. Therefore, it is not necessary to remove the release paper and throw it away every time the shield 1 is used, and it is possible to provide a protective tool for protecting the eyes that is more accessible to medical workers.

Moreover, in the shield 1 according to the present embodiment, the connecting portion 20 may be made of the adhesive 40 . In this case, when the shield 1 is removed from the non-woven fabric mask 2, the effect of minimizing the peeling sound is exhibited. In addition, since the shield 1 can be easily removed from the non-woven fabric mask 2, it is easy to dispose and can provide safe eye protectors for medical workers.

Moreover, in the shield 1 according to the present embodiment, the connection strength of the adhesive 40 to the nonwoven fabric mask 2 may be 1.5 N or less. In this case, it is possible to provide an eye protector that can be used repeatedly while wearing the nonwoven fabric mask 2 without causing excessive raising of the nonwoven fabric.

In the shield 1 according to this embodiment, the lower edge 12 is formed with a notch 16 at a position corresponding to the portion of the non-woven fabric mask 2 that covers the nose. Therefore, when the user attaches the shield 1 while wearing the non-woven fabric mask 2, the user can attach the shield 1 by aligning the notch 16 of the shield 1 with the position of the nose. As described above, alignment when attaching the shield 1 can be easily performed.

In the shield 1 according to the present embodiment, the connecting portions 20 are formed at least at positions corresponding to both end portions of the nonwoven fabric mask 2 in the width direction. As a result, the shield 1 can be attached to the non-woven mask 2 in a well-balanced manner, compared to the case where the connecting portion 20 is formed only at the central position in the width direction of the non-woven mask 2, for example.

Further, the eye protection method according to the present embodiment is a method for protecting the eyes of a user wearing the nonwoven fabric mask 2, and includes a shield 1 having a connecting portion 20 detachably fixed to the nonwoven fabric mask 2. , is attached to the non-woven mask 2 via the connecting part 20, and the shield 1 protects the eyes. By adopting such a method, it is possible to obtain the same functions and effects as those of the shield 1 described above.

Further, in the eye protection method according to the present invention, the shield 1 is attached to the nonwoven fabric mask 2 worn by the user, and the shield 1 is removed from the nonwoven fabric mask 2 worn by the user. This allows the user to easily protect the eyes.

The invention is not limited to the embodiments described above.

The shape and size of the shield 1 and the shape and size of the connecting portion 20 according to the above embodiment are merely examples, and may be changed as appropriate. For example, like the shield 100 shown in FIG. 4( a ), the entire lower edge 12 may extend straight without forming a notch in the lower edge 12 . Along with this, the connecting portion 20 is also formed on the shield 100 so as to extend straight along the lower edge portion 12 . Also, as in the shield 110 shown in FIG. 4B, a notch 116 smaller than the notch 16 shown in FIG. 2 may be formed. The depth dimension of this notch portion 116 is smaller than the width of the connecting portion 20 . Accordingly, the connecting portion 20 is configured as one continuous member without being divided at the position of the notch portion 116 . Also, as in the shield 100 shown in FIG. 4(c), a notch 126 larger than the notch 16 shown in FIG. 2 may be formed. Also, the position where the connecting portion 20 is formed may be separated from the lower edge portion 12 . In the example shown in FIG. 4( c ), the connecting portion 20 is formed at a position corresponding to the V-shaped trough portion of the notch portion 126 and is spaced upward from the lower edge portion 12 . 2, 4(a) and 4(b), etc., the connecting portion 20 may be separated from the lower edge portion 12 as well.

Also, the shield does not have to be fan-shaped like the shields 1, 100, 110, and 120, and may have any shape such as rectangular, trapezoidal, circular, elliptical, or oval. Further, in the above-described embodiment, the connecting portion 20 is formed so as to extend over substantially the entire width direction of the shield 1 (except for the position of the notch portion), but it may be formed partially. For example, the connecting portions 20 may be partially formed at least at positions corresponding to both end portions in the width direction of the non-woven fabric mask 2, and the connecting portions 20 may not be formed near the central portion. Further, the connecting portion 20 may be formed so as to be separated from the edge portions 13 on both sides in the width direction of the shield. In addition, although the connecting portion 20 is configured to have a predetermined width and extend in a strip shape, the shape is not limited to this. For example, the connecting portion 20 formed in a rectangular shape or a circular shape may be arranged at one or a plurality of predetermined positions on the shield.

[Example]
A shield according to one embodiment of the present invention will be specifically described below based on examples, but the configuration of the shield is not limited to the following examples.

First, shields were prepared as Examples 1 to 6 and Comparative Examples 1 to 3, which employ connecting portions according to mutually different conditions. In each embodiment, the shape of the shield shown in FIG. 4(b) was adopted, and the size of the connecting portion was 15 mm in width and 50 mm in length. In Examples 1 to 6 and Comparative Examples 1 to 3, mechanical engaging means is adopted as the connecting portion, and the pin density and pin height are different from each other (for detailed conditions, see FIGS. 7 and 8). ). Moreover, in Example 5, the connecting part was formed by attaching a weakly adhesive double-faced tape to the shield. Moreover, in Example 6, the connecting portion was formed by attaching an adhesive double-sided tape to the shield. For these examples and comparative examples, the connection strength to the non-woven fabric mask was measured, and various tests regarding use were conducted. The connection strength was measured when the shield was attached to the non-woven fabric mask for the first time, and the connection strength was measured after repeatedly attaching and detaching the shield 10 times. Three types of non-woven fabric masks available on the market were selected and used. In addition, as a test for use, the ease of attaching the shield to the non-woven mask, whether the shield does not come off while attached to the non-woven mask, whether the shield can be attached to the non-woven mask even after repeated use, A test was conducted on the easiness of removing the shield from the non-woven fabric mask and the state of the mask after removing the shield.

As shown in FIG. 7, in Examples 1 to 4, the connection strength of the connection portion to the nonwoven mask can be 0.05 N or more for any nonwoven mask and even after repeated use. confirmed. Even when the connection strength was the weakest value (the connection strength with respect to the non-woven mask 2 after 10 repetitions in Example 4), it was possible to achieve 0.05 N or more. In Examples 1 to 4, good results were obtained in all test items. On the other hand, as shown in FIG. 8, in Comparative Examples 1 to 3, it was confirmed that the connection strength of the connection portion to the nonwoven mask was less than 0.05 N for all nonwoven masks. Moreover, in Comparative Examples 1 to 3, it was confirmed that the shield could not be attached to the nonwoven fabric mask.

As shown in FIG. 9, in Example 5, it was confirmed that the connection strength of the connection portion to the nonwoven mask can be 0.05 N or more for any nonwoven mask and even after repeated use. rice field. Moreover, in Example 5, it was confirmed that the connection strength of the connecting portion to the nonwoven mask can be 1.5 N or less for any nonwoven mask and even after repeated use. In Example 5, good results were obtained in all test items. In Example 6, it was confirmed that the connection strength of the connection portion to the nonwoven mask can be 0.05 N or more for any nonwoven mask and even after repeated use. Moreover, in Example 6, it was confirmed that the connection strength of the connection portion to the nonwoven mask was 1.5 N or more for any nonwoven mask and even after repeated use. In this case, when the shield is removed from the non-woven mask, excessive fuzzing occurs on the surface non-woven fabric, and the fuzz on the surface of the non-woven mask is taken away by the joint, damaging the surface of the non-woven mask. It was confirmed that good results were obtained.
