  The nonwoven fabric mask 2 is formed of a rectangular mask member, and may be formed of a single member or a multilayer member. Moreover, you may provide the flexible metal insert (not shown) along the edge 2a concerning a nose bridge. Rubber strings 3 for attaching to the ears are attached to both ends 2c, 2c in the width direction (long side direction) of the nonwoven fabric mask 2. In addition, the attachment aspect of the nonwoven fabric mask 2 is not specifically limited, The type which does not need to be hung on an ear | edge may be sufficient, and the type which connects a string behind a head may be sufficient. The front surface 2d of the nonwoven fabric mask 2 is a surface to which the shield 1 is attached. The nonwoven fabric mask 2 has at least a front surface 2d made of a nonwoven fabric. However, a part of the mask member constituting 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 lower edge portion 12 side of the shield 1 and overlapped with the nonwoven fabric mask 2 and is formed on the attachment edge E1 attached to the nonwoven fabric mask 2 and the upper edge portion 11 side of the shield 1 and used. Eye protection part E2 which can protect a person's eyes. The shield 1 is attached to the front surface 2d of the nonwoven fabric mask 2 so that the attachment portion E1 on the lower edge portion 12 side is overlaid, and the shield 1 is detachably attached in a state where the nonwoven fabric mask 2 is attached to the human body. The attachment portion E1 is formed with a connecting portion 20 that is detachably fixed to the nonwoven fabric mask 2. The shield 1 is formed of a transparent and flexible planar member. As a material for the shield 1, polyester, acrylic resin, polycarbonate, polystyrene, or the like is used. The polymer film on which the shield 1 is formed has a thickness of 0.05 mm to 0.25 mm, most preferably 0.1 mm, and imparts the desired flexibility to the shield 1. The term “flexible” means that the elastic modulus of the material from which the shield 1 is formed is about 400 MPa to 7,000 MPa, preferably about 1,200 MPa to 5,000 MPa, most preferably 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 are merely examples, and any configuration can be used as long as it can be attached to the nonwoven fabric mask 2 and can protect the eyes of the user. It may be. As shown in FIG. 2, the shield 1 has a lower edge portion 12 that is an edge of a side connected to the nonwoven fabric mask 2 (that is, a lower side in the usage state of the nonwoven fabric mask 2), and a side opposite to the lower edge portion 12. That is, it has the upper edge part 11 which is an edge of (the upper end part in the use state of the nonwoven fabric mask 2), and both edge parts 13 and 13 which are edges in the width direction of the nonwoven fabric mask 2. The upper edge portion 11 extends along the width direction of the shield 1 so as to draw an arc that protrudes to the opposite side of the lower edge portion 12 at a position separated from the edge portion 2a of the nonwoven fabric mask 2 at the time of attachment. ing. The dimension L1 between the apex 11a of the upper edge part 11 (the point farthest from the edge part 2a of the nonwoven fabric mask 2) and the lower edge part 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 extending portion 14 extending along the width direction, and a V-shaped cutout 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 covering the nose in the nonwoven fabric mask 2. Although the depth dimension L2 of the notch 16 is not particularly limited, it is set to 10 to 25 mm. Further, the angle α of the notch 16 is not particularly limited, but is set to 45 to 135 °. The extending portion 14 is formed on both sides in the width direction with the notch portion 16 at the center position interposed therebetween. In this embodiment, the extension part 14 is extended to the outer side rather than the both ends 2c and 2c of the nonwoven fabric mask 2 at the time of attachment. Moreover, both the edge parts 13 and 13 are inclined and extended so that it may spread as it goes to the upper edge part 11 side. The shield 1 is divided into a base portion 17 provided in a region near the center position in the width direction and corresponding to both eyes of the user, and lateral portions 18 provided on both sides in the width direction of the base portion 17. The The horizontal portion 18 is configured to extend toward the user's ear side during use. Although the dimension L3 between the front-end | tip parts 18a and 18a of the width direction of the horizontal part 18, ie, the full length of the width direction of the shield 1, is not specifically limited, It sets to 180-350 mm. In such a shield 1, at least a region closer to the lower edge portion 12 than the center position in the vertical direction is defined as the attachment portion E1. Moreover, the area | region of the upper edge part 11 side rather than the attaching part E1 is defined as the eye protection part E2.

  The connecting part 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 connection part 20 can cancel | release connection with the nonwoven fabric mask 2, and makes it possible to remove the shield 1 from the nonwoven fabric mask 2 by the said cancellation | release. Moreover, the connection part 20 is good also as enabling it to perform connection and cancellation | release with respect to the nonwoven fabric mask 2 repeatedly. In this case, the shield 1 can be repeatedly attached to and detached from the nonwoven fabric mask 2. In addition, the shield 1 is attached to the nonwoven fabric mask 2 by the connecting portion 20 with such a strength (connection strength) that the shield 1 can be detachably attached to the nonwoven fabric mask 2 with the nonwoven fabric mask 2 attached to the human body. Fixed. Since it is such connection strength, the shield 1 can be attached to the nonwoven fabric mask 2 in a state of being attached to the user via the connection part 20 and is in a state of being attached to the user. It becomes the structure which can be removed from the nonwoven fabric mask 2. FIG. The connection strength by the connection part 20 is set to such a strength that the shield 1 does not fall when the user connects the connection part 20 of the shield 1 to the nonwoven fabric mask 2 while wearing the nonwoven fabric mask 2. The connection strength is preferably set to a strength at which the shield 1 does not fall even when the user moves the head while working with the shield 1 attached to the nonwoven fabric mask 2. Further, the connection strength is set to a strength that allows the shield 1 to be removed without applying an excessive force by pulling the shield 1 while the user is wearing the nonwoven fabric mask 2. Further, the connection strength can be removed without undue damage to the nonwoven fabric mask 2 when the shield 1 is removed (for example, the nonwoven fabric mask 2 is torn, broken, or excessively fuzzy on the surface). It may be set to a degree of strength.

  The connection part 20 is formed in the attachment part E1 in the shield 1. Moreover, the connection part 20 is formed in the back surface (surface which opposes a user's eyes at the time of mounting | wearing) of the shield 1. FIG. The connecting portion 20 is configured by fixing a planar member connectable to the nonwoven fabric mask 2 to the back surface of the attaching portion E1 of the shield 1. In the present embodiment, the connecting portion 20 is formed so as to extend along the extending portion 14 of the lower edge portion 12. The connecting portion 20 is configured to have a predetermined width and extend in a strip shape. 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 portion 16, Their total length) may be set. In the present embodiment, the lower edge portion 20 a of the connecting portion 20 coincides with the extending portion 14 of the lower edge portion 12 of the shield 1, and the end portions 20 b and 20 b of the connecting portion 20 are the edge portion 13 of the shield 1. , 13. With such a configuration, the connecting portion 20 is formed at positions corresponding to substantially the entire width direction of the nonwoven fabric mask 2 including positions corresponding to both end portions in the width direction of the nonwoven fabric mask 2.

  When the shield 1 is attached to the nonwoven fabric mask 2, the attachment portion E1 of the shield 1 is overlapped with the front surface 2d of the nonwoven fabric mask 2, and the connecting portion 20 is pressed against the front surface 2d of the nonwoven fabric mask 2 to be connected. It should be noted that the size of the attachment portion E1 (the amount of the shield 1 overlapped with the nonwoven fabric mask 2), that is, where the connecting portion 20 is on the front surface 2d of the nonwoven fabric mask 2 (how far away from the edge 2a of the nonwoven fabric mask 2). There is no particular limitation as to whether or not they are connected, as long as the user's eyes can be sufficiently covered with the shield 1. For example, the dimension L4 of the attachment portion E1, which is a region where the shield 1 is overlaid on the nonwoven fabric mask 2, may be set to about 15 to 50 mm (see FIG. 2B). However, the boundary line between the attachment part E1 and the eye protection part E2 does not need to be clearly defined on the product. It suffices that at least the region closer to the lower edge 12 than the upper edge 20c of the connecting part 20 functions as the attachment part E1. In addition, the mark which shows the attachment part E1 (namely, the mark which shows the standard of how much the shield 1 is overlap | superposed on the nonwoven fabric mask 2) may be shown by the shield 1. FIG. Further, depending on how the user attaches, a part of the eye protection part E2 may be superimposed on the nonwoven fabric mask 2. The shield 1 is preferably arranged so that the center line in the width direction of the shield 1 and the center line in the width direction of the nonwoven fabric mask 2 substantially coincide. Moreover, it is preferable that the notch part 16 is arrange | positioned in the position corresponding to the part which covers a nose in a nonwoven fabric mask.

  As long as it can connect with the front surface 2d of the nonwoven fabric mask 2, as a structure of the connection part 20, all the structures are employable. 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. 3A, the connecting portion 20 may be configured by mechanical engagement means 30. As the mechanical engagement means 30, a surface fastener (mechanical fastener) etc. are mentioned, for example. The mechanical engagement means 30 has a structure in which a plurality of engagement elements (hooks) 31 are formed integrally with the base material 32 and each engagement element 31 is provided directly on the base material 32. . The back surface of the base material 32 of the mechanical engagement means 30 (the surface opposite to the surface on which the engagement element 31 is formed) is fixed to the back surface 1b of the shield 1 with an adhesive or an adhesive. The fixing strength of the part is higher than at least the connecting strength of the connecting part 20 to the nonwoven fabric mask 2. In addition, from the viewpoint that the connection strength does not become excessively high, damage to the nonwoven fabric mask 2 during removal is suppressed, and the nonwoven fabric mask 2 is detachably fixed, the mechanical engagement means It is preferable to adopt 30 having a connection strength with respect to the nonwoven fabric mask 2 of 0.05 N or more. On the other hand, the upper limit value of the connection strength is not particularly limited, and mechanical engagement means 30 that can be generally used by those skilled in the art for nonwoven fabrics can be generally used. In some embodiments, the upper limit value of the connection strength may be 1.5 N or less.

  In the specification, “connection strength” 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 a portion of the connecting portion 20 is overlapped with the nonwoven fabric mask 2. Thereafter, the cylindrical roller having a smooth surface with a mass of 1 kg is reciprocated twice to connect the nonwoven fabric mask 2 and the shield 1. Next, in a state where the nonwoven fabric mask 2 is fixed to a jig, the shield 1 is picked by a clip of a tensile tester, and the shield 1 is lifted with respect to the nonwoven fabric mask 2 at a speed of 300 mm / min in the 90-degree direction. Peel off like so. The force required at this time is defined as “the connection strength of the connecting portion with respect to the nonwoven fabric mask”.

  As shown in FIG. 3A, the engaging element 31 of this embodiment includes a column part 31a extending from the base material 32 and a head part 31b formed at the tip of the column part 31a. The shape of the engagement element 31 is not particularly limited, and may be set as appropriate based on the dimensions (length, width) of the mechanical engagement means 30 and the degree of extensibility. For example, as shown in FIG. 5A, the engaging element 31 may include a columnar column portion 31a and a hemispherical head portion 31b. The head portion 31b may be provided with a plurality of grooves on a disc as shown in FIG. 5 (b), or may be disc-like as shown in FIG. 5 (c). . Or as shown to Fig.6 (a), the element 31 for engagement may be provided with the prism-shaped column part 31a and the arrowhead-shaped head part 31b. As shown in FIG. 6B, the engaging element 31 may include a column part 31a extending obliquely upward and a head part 31b bent obliquely downward from the tip of the column part 31a. Moreover, as shown in FIG.6 (c), the element 31 for engagement is provided with the pillar part 31a extended upwards, and the head part 31b extended so that it may curve to one side in the horizontal direction from the upper end of the said pillar part 31a, The overall shape may be a J-shape. Further, as shown in FIG. 6D, the engaging element 31 includes a column part 31a extending upward, and a head part 31b extending so as to be bifurcated from the upper end of the column part 31a and to bend in both directions. And may be provided.

  The height of the engaging element 31 may be 0.25 to 0.75 mm, and may be 0.38 to 0.68 mm. Further, the density of the engaging element 31 may be 900 to 2400 lines / Inch2, and may be 900 to 1600 lines / 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. The dimensions shown. If it is this range, the appropriate connection strength requested | required as the connection part 20 of the shield 1 can be ensured irrespective of the shape of the element 31 for engagement. In addition, when the shield 1 is attached with the user wearing the nonwoven fabric mask 2, the connection portion 20 can be connected to the nonwoven fabric mask 2 without being excessively pressed against the nonwoven fabric mask 2. Further, even if the user shakes his / her head with the shield 1 attached to the nonwoven fabric mask 2, the shield is not peeled off. Moreover, when removing, a user can remove with the force of the grade which pulls the shield 1 with one hand. In addition, it is possible to avoid leaving noticeable damage to the nonwoven fabric mask when removed. When it is lower than the connection strength obtained in the above numerical range, it is difficult to maintain the state where the shield 1 is attached to the nonwoven fabric mask 2. When it is higher than the connection strength obtained in the above numerical range, damage may be left on the nonwoven fabric mask 2 when the shield 1 is removed.

  The material of the mechanical engagement means 30 having extensibility is a thermoplastic resin or the like, for example, a mixture of polypropylene resin (PP) and polyethylene resin (PE), or ethylene-vinyl acetate copolymer (EVA) resin. As mentioned. When a mixture of PP and PE is used, PP and PE may be mixed in a weight ratio of about 95: 5 to 30:70. When the amount of PP exceeds this upper limit, the characteristics of PP become dominant and the engagement element tends to become hard. On the contrary, when the amount of PP falls below the lower limit, the engaging force of the engaging element becomes weak. PP may be either a homopolymer or a copolymer. Examples of PE include low density polyethylene (LDPE), high density polyethylene (HDPE), and linear low density polyethylene (LLDPE).

  Further, as shown in FIG. 3B, the connecting portion 20 may be configured by an adhesive 40. Specifically, the connecting part 20 may be constituted by a tape 41 including a layer of the adhesive 40. The tape 41 includes a layer of the adhesive 40 on the base material 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 the part is higher than at least the connection strength between the connection part 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 the part is higher than at least the connecting strength of the connecting part 20 to the nonwoven fabric mask 2. The adhesive 40 may have a characteristic of an adhesive strength of 0.05 N or more with respect to the nonwoven fabric mask 2 and may have a characteristic of 0.05 to 1.5 N. As the adhesive 40, for example, an acrylic adhesive, a synthetic rubber adhesive, or a silicon adhesive is employed. If it is this range, the appropriate connection strength requested | required as the connection part 20 of the shield 1 can be ensured. In addition, when the shield 1 is attached with the user wearing the nonwoven fabric mask 2, the connection portion 20 can be connected to the nonwoven fabric mask 2 without being excessively pressed against the nonwoven fabric mask 2. Further, even if the user shakes his / her head with the shield 1 attached to the nonwoven fabric mask 2, the shield is not peeled off. Moreover, when removing, a user can remove with the force of the grade which pulls the shield 1 with one hand. In addition, it is possible to avoid leaving noticeable damage to the nonwoven fabric mask when removed. When it is lower than the connection strength obtained in the above numerical range, it is difficult to maintain the state where the shield 1 is attached to the nonwoven fabric mask 2. When it is higher than the connection strength obtained in the above numerical range, damage may be left on the nonwoven fabric mask 2 when the shield 1 is removed.

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

  Here, conventionally, a mask with a shield in which a shield is fixed to the mask by welding or the like is known as means for protecting the eyes. Such a shielded mask is used in a medical field such as a hospital. For example, a package of multiple layers of shielded masks is packaged and installed in a hospital rack, etc., and the user removes the shielded mask from the package and installs it when protecting the eyes. To do. However, in the medical field, a user often wears a normal type mask, and it is necessary to remove the normal type mask once to attach a shielded mask. In addition, after the work requiring eye protection was completed, it was necessary to remove the entire shielded mask and mount a normal type mask again. Further, such a mask with a shield has a larger area than a normal mask, and an improvement in handling convenience has been demanded.

  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 on the attachment portion E1 on the lower edge portion 12 side of the shield 1. As a result, when the attachment portion E1 of the shield 1 is superimposed on the front surface 2d of the nonwoven fabric mask 2, the connecting portion 20 is detachably fixed to the front surface 2d of the nonwoven fabric mask 2 so that the shield 1 is attached to the nonwoven fabric mask 2. It is done. With such a configuration, the shield 1 can be attached without removing the non-woven mask 2 from the face while the non-woven mask 2 is attached to the user. Therefore, when performing a work that needs to protect the eyes, the user only needs to attach a shield to the non-woven fabric mask 2 that has already been worn. Only the shield 1 needs to be removed. The shield 1 can be handled as a member independent of the nonwoven fabric mask 2. Therefore, when a plurality of shields 1 are overlapped and packaged, the package can be made more compact than a conventional shielded mask package.

  Moreover, since the shield 1 according to the present embodiment is a member independent of the nonwoven fabric mask 2, for example, it is possible to store the shield 1 and discard only the nonwoven fabric mask 2, or only the shield 1 is stored. It is also possible to discard and continue to use the non-woven mask 2. Further, for example, when the shield and the mask are fixed with a clip or the like, it is necessary to prepare the clip as a separate member. However, in the present embodiment, since the connecting portion 20 is fixed to the shield 1 itself, There is no need to prepare a separate member. As described above, the convenience of handling the shield for protecting the eyes can be improved.

  Moreover, in the shield 1 which concerns on this embodiment, the connection strength with respect to the nonwoven fabric mask 2 of the connection part 20 may be 0.05 N or more. Thereby, 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 the present embodiment, the connecting portion 20 may be configured by mechanical engagement means 30 having an engagement element 31. In this case, since the connection strength does not easily decrease even when used repeatedly, the shield 1 can be used repeatedly while the nonwoven fabric mask 2 is attached. Moreover, since the shield 1 can be easily removed from the nonwoven fabric mask 2, it is easy to dispose and can provide a safe eye protector for medical personnel. Then, without using a release paper like an adhesive, the shield 1 can be stacked and stored in a package, and then placed on a rack or the like. This eliminates the need to peel or discard the release paper each time the shield 1 is used, and can provide a protective device for protecting eyes that are more accessible to medical professionals.

  Further, in the shield 1 according to the present embodiment, the connecting portion 20 may be configured by the adhesive 40. In this case, when removing the shield 1 from the nonwoven fabric mask 2, the effect that the peeling sound is minimal is exhibited. Moreover, since the shield 1 can be easily removed from the nonwoven fabric mask 2, it is easy to dispose and can provide a safe eye protector for medical personnel.

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

  In the shield 1 according to the present embodiment, a cutout portion 16 is formed in the lower edge portion 12 at a position corresponding to a portion covering the nose in the nonwoven fabric mask 2. Therefore, when the user attaches the shield 1 with the nonwoven fabric mask 2 attached, the user can attach the cutout portion 16 of the shield 1 in alignment with the position of the nose. As described above, alignment when the shield 1 is attached can be easily performed.

  In the shield 1 according to this embodiment, the connecting portion 20 is formed at positions corresponding to at least both end portions in the width direction of the nonwoven fabric mask 2. Thereby, for example, the shield 1 can be attached to the nonwoven fabric mask 2 in a balanced manner as compared with the case where the connecting portion 20 is formed only at the center position in the width direction of the nonwoven fabric mask 2.

  The eye protection method according to the present embodiment is an eye protection method for protecting the eye of the user wearing the nonwoven fabric mask 2, and includes the shield 1 having the connecting portion 20 that is detachably fixed to the nonwoven fabric mask 2. Then, it is attached to the nonwoven fabric mask 2 through the connecting portion 20 and the eyes are protected by the shield 1. By adopting such a method, the same operation and effect as the above-described shield 1 can be achieved.

  Moreover, in the eye protection method according to the present invention, the shield 1 is attached to the nonwoven fabric mask 2 attached to the user, and the shield 1 is removed from the nonwoven fabric mask 2 attached to the user. As a result, the user can easily protect the eyes.

  The present invention is not limited to the above-described embodiment.

  The shape / size of the shield 1 according to the above-described embodiment and the shape / size of the connecting portion 20 are merely examples, and may be changed as appropriate. For example, like the shield 100 shown in FIG. 4A, the entire lower edge portion 12 may extend straight without forming a notch in the lower edge portion 12. Accordingly, the connecting portion 20 is also formed on the shield 100 so as to extend straight along the lower edge portion 12. Moreover, you may form the notch part 116 small compared with the notch part 16 shown in FIG. 2 like the shield 110 shown in FIG.4 (b). The depth dimension of the notch 116 is smaller than the width of the connecting portion 20. Accordingly, the connecting portion 20 is configured as a single continuous member without being divided at the position of the notch portion 116. Moreover, you may form the notch part 126 large compared with the notch part 16 shown in FIG. 2 like the shield 100 shown in FIG.4 (c). Further, the position where the connecting portion 20 is formed may be separated from the lower edge portion 12. In the example shown in FIG. 4C, the connecting portion 20 is formed at a position corresponding to the V-shaped valley portion of the notch portion 126 and is separated from the lower edge portion 12 to the upper position. In addition, also in FIG. 2, FIG. 4 (a), (b) etc., the connection part 20 may be spaced apart from the lower edge part 12. FIG.

  Further, the shield does not have to have a fan shape like the shields 1, 100, 110, and 120, and may have any shape such as a rectangle, a trapezoid, a circle, an ellipse, and an oval. Moreover, although the connection part 20 is formed so that it may extend over the substantially whole area of the width direction of the shield 1 (except for the position of a notch part) in the above-mentioned embodiment, it may be formed partially. For example, the connecting portion 20 may be partially formed at positions corresponding to at least both end portions in the width direction of the nonwoven fabric mask 2, and the connecting portion 20 may not be formed in the vicinity of the central portion. Moreover, the connection part 20 may be formed so that it may space apart from the edge part 13 of the both sides of the width direction of a shield. Moreover, although the connection part 20 is comprised so that it may have a predetermined | prescribed width | variety and may be extended in strip | belt shape, it is not limited to such a shape. For example, you may arrange | position the connection part 20 formed in the rectangular shape or the circular shape to the predetermined position of a shield in one place or multiple places.

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

  First, the shield which employ | adopted the connection part which concerns on mutually different conditions was prepared as Examples 1-6 and Comparative Examples 1-3. In any of the examples, the shape of the shield shown in FIG. 4B was adopted, and the size of the connecting portion was 15 mm wide and 50 mm long. In Examples 1 to 6 and Comparative Examples 1 to 3, mechanical engagement means is employed as the connecting portion, and the pin density and the pin height are different from each other (refer to FIGS. 7 and 8 for detailed conditions). ). Moreover, in Example 5, it was set as the connection part by affixing a weak adhesive double-sided tape on a shield. Moreover, in Example 6, it was set as the connection part by sticking an adhesive double-sided tape on a shield. About these Examples and comparative examples, while performing the measurement of the connection strength with respect to a nonwoven fabric mask, the various tests regarding use were done. The connection strength was measured by measuring the connection strength when the shield was attached to the nonwoven fabric mask for the first time, and measuring the connection strength after repeating attachment and detachment 10 times. Three types of non-woven masks used in the market were selected and used. Also, as a test for use, ease of attachment when attaching the shield to the nonwoven fabric mask, whether or not the shield is attached to the nonwoven fabric mask, whether the shield can be attached to the nonwoven fabric mask even when used repeatedly, The test was conducted on the ease of removal when removing the shield from the nonwoven 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 with respect to the nonwoven fabric mask can be 0.05 N or more even for any nonwoven fabric mask and after repeated use. confirmed. Even when the connection strength was the weakest value (connection strength with respect to the nonwoven fabric mask 2 after 10 repetitions of Example 4), it could be 0.05 N or more. And in Examples 1-4, the favorable result was obtained in any test item. On the other hand, as shown in FIG. 8, in Comparative Examples 1 to 3, it was confirmed that the connection strength of the connecting portion with respect to the nonwoven fabric mask was smaller than 0.05 N for any nonwoven fabric mask. Moreover, in the comparative examples 1-3, the point which cannot attach a shield to a nonwoven fabric mask was confirmed.

  As shown in FIG. 9, in Example 5, it was confirmed that the connection strength of the connecting portion with respect to the nonwoven fabric mask can be 0.05 N or more even for any nonwoven fabric mask and after repeated use. It was. Moreover, in Example 5, it was confirmed that the connection strength with respect to the nonwoven fabric mask of the connection portion can be 1.5 N or less even for any nonwoven fabric mask and after repeated use. In Example 5, good results were obtained for any test items. In Example 6, it was confirmed that the connection strength of the connection portion with respect to the nonwoven fabric mask can be 0.05 N or more even for any nonwoven fabric mask and after repeated use. Further, in Example 6, it was confirmed that the connection strength of the connecting portion with respect to the nonwoven fabric mask was 1.5 N or more even for any nonwoven fabric mask and after repeated use. In this case, when removing the shield from the nonwoven fabric mask, the surface nonwoven fabric is excessively fuzzed, and the surface of the nonwoven fabric mask is brought by the joint and the surface of the nonwoven fabric mask is damaged.
