Description of the Invention: [Technical Field] The present invention relates to a mask, and more particularly to a mask for preventing a gap from being formed on both sides of a nose bridge when worn. [Prior Art] A widely used disposable mask is used. However, such a mask has the following problems, and when it is worn, a gap is formed on both sides of the bridge of the nose, and pollen or dust can invade from the gap. In the patent document, there is disclosed a mask comprising a non-woven mask body and a non-woven thin cup attached to the inner side thereof, and mounted on the left and right upper ends of the thin cup at a predetermined interval The reinforcing sheet is formed of a strip of a synthetic resin material having flexibility and inelasticity. The mask according to Patent Document 1 can provide a mask which does not cause a gap between the peripheral portion of the mask and the skin. [Patent Document 1] Japanese Laid-Open Patent Publication No. 2005-328937 [Problems to be Solved by the Invention] In the mask of Patent Document 1, the thin cup is composed of a low-stretch non-woven fabric and does not fit on the nostrils or the mouth, so Conversation and breathing comfortably. Further, since the reinforcing piece of the upper portion of the thin cup is bent along the nose portion, the upper portion of the thin opening cup can be brought into contact with the face. Since the strong film is composed of a plastically deformed synthetic resin material, unlike the conventional synthetic resin, that is, no elastic deformation is produced, the shape along the nasal cavity portion is maintained. Since the reverse side is a material that is plastically deformed, when the sheet expands or contracts or applies an external force to the mask, it is impossible to return to the original shape when it is shaped like a human. Thus, there is room for improvement in the shape maintenance of the mask when it is used. H6819-980717.doc 1325330 The above problems have been made. The object of the present invention is to provide a mask which can prevent a gap from being formed on both sides of the bridge of the nose and improve the wearing feeling when worn. Further, the purpose of X month is to provide a mask which is improved in shape maintainability when an external force is applied. SUMMARY OF THE INVENTION The present invention for solving the above problems has been proposed to include a mask covering a mouth of a wearer and a covering portion of a bridge of the nose.

Also, place the mask on the side of the skin that is in contact with the wearer's skin. [Effects of the Invention] According to the present invention, it is possible to provide a mask which can prevent the occurrence of a slit on both sides of the bridge of the nose when worn and which has improved wearing feeling. Further, the present invention can provide a mask which is improved in shape maintainability when an external force is applied. [Embodiment] A mask facing the present invention will be described with reference to the accompanying drawings. Figure 1 is a perspective view of a mask 1 of the present invention. The mask 1 is provided with a covering portion 2 covering the mouth of the wearer and the bridge of the nose, and is a three-dimensional mask which is in the shape of a cup when worn. The covering portion 2 is formed by joining a pair of left and right thin members 2a, 2a, and a joining edge 2b is formed at the joint portion. The joint edges extend along the longitudinal center line, and the longitudinal center line divides the cover portion 2 to the left and right. Further, a pair of left and right belt-like members 4 are attached to both sides of the interface side 2b at the upper end portion of the covering portion 2, and are covered by the covering member 5, and extend in the lateral direction along the upper end of the covering portion 2 at a predetermined interval. Further, the ear hook portion 3 is provided on the left and right sides of the covering portion 2. When the mask is worn, the earloop 3 is hung on both ears and covers the nose and the mouth by the cover portion 2, and then the left and right pair of belt members 4 are pressed by fingers to be plastically deformed to be attached to the side of the nose bridge. cheek. Thereby, it is possible to prevent a gap from being formed on both sides of the bridge of the nose. The covering portion 2 of the mask 1 is formed using a thermoplastic synthetic fiber nonwoven fabric. The fiber non-woven fabric is better than the 116819-980717.doc 1325330 because of the good touch of the skin and the comfortable wearing of the mask. For the covering portion 2, it is preferable to use the genus, which is very rigid according to the cantilever method (JIS L1096) and has a rigidity of 130 to 280 mm. If the stiffness is lower than this standard, the helmet method maintains the shape of the mask. On the contrary, if the right stiffness of the _丨_一 & * is towards this standard, it feels like a plastic sheet, which is detrimental to the wearing feeling.

Further, when the band member 4 is fixed to the cover portion 2 or the cover member 5, a hot melt adhesive can be used. Since the plastic deformable material does not use a metal such as a wire but a synthetic resin, the fusion bonding of the hot melt adhesive can be easily performed, and the increase in the weight of the mask can be suppressed. The member 4 is symmetrically mounted with respect to the nose bridge. At the upper end of the cover portion 2. It is desirable that if it is installed along the upper side of the cover portion 2, it is possible to more effectively prevent the occurrence of a gap on both sides of the bridge of the nose. Left and right - the special between the strip members 4 116819-9807I7.doc • 9- !32533 〇 interval, for example, can be determined according to the data of the average face shape of the person. Further, the band member 4 can be attached to any of the skin side 'outsides'. When mounted on the outside, since the band member 4 does not come into contact with the wearer's skin, the mask 1 is comfortable to wear. Further, since the portion in contact with the bridge of the nose has no band member 4, it can be easily applied to a three-dimensional mask, which is folded flat before use to change it into a cup shape. Since the belt-shaped member 4 is attached to the upper end portion of the cover portion 2 with a certain interval therebetween, the nose portion of the wearer is a soft fiber non-woven fabric, and the sides of the nose to the face frequency are fitted with a plastic deformation band. Part of the member 4. Therefore, when the upper part of the cover 2 is in contact with the bridge of the nose, the fiber non-woven fabric is bent and conformed along the shape of the bridge of the nose. Further, the part of the bridge of the nose to the cheek is pressed with a finger. The member 4 is plastically deformed, and the upper end portion of the covering portion 2 is attached to the tendon of the wearer. Thus, the mask (10) of the present invention can be prevented from being attached along a face having a personal difference. A gap is formed on both sides of the bridge of the nose. Further, since the portion which is in contact with the bridge of the wearer has no band member 4, the wearing feeling can be made more comfortable. Further, the inventors of the present application found that the rigidity of the covering member 5 is low. The covering structure of the strip-shaped member * as described below is used to cover the second and second sub-woods, whereby the P-pad can be used to add an external force or suppress the deformation of the strip-shaped member 4 to maintain a specific shape of the mask.

In addition, the lower side of the figure in Fig. 2 is the skin of the wearer's muscle 116819-980717.doc 1325330. In the following description, the opposite side of the skin side is referred to as the upper side of the figure. Fig. 3 is a model diagram for explaining a method of measuring shape maintenance. <Example 1> As shown in Fig. 2(a), in the present embodiment, the belt-shaped member 4 is attached to the outside of the covering portion 2. Specifically, after the band member 4 is fixed to the cover member 5 by the hot melt adhesive 6, the cover member 5 is fixed to the cover portion 2 by the hot melt adhesive 6. At this time, the band member 4 is free. In the state of the cover portion 2, the free state in the present application means that the two members are not joined to each other and are independent of each other, and even if one of the members is displaced, the two members are not directly deformed by the displacement.

When the measured value is 7 mm or less, the shape retention property is evaluated as ".". When the measured value exceeds 7 mm, the shape retention property is evaluated to be "X". The table indicates the measured knot. When the measured value is 7 or less, it is "." because the distance between the rear crotch portion 2 and the nose of the wearer, that is, the gap is 30% or less when the band member 4 is not included.

When the cover material 5 is joined and the cover portion 2 and the cover member 5 are kept free, the shape retention property is good. Moreover, the influence of the arrangement of the belt-shaped member 4 and whether or not it is joined to the cover member 5 is small. According to the third embodiment and the second comparative example, since the covering portion 2 and the covering member 5 are present, the shape retainability of the strip-shaped member * is lower than that of the strip-shaped member 4. This case can be explained: the strip member 4 The shape maintenance is affected by the covering portion 2 and the covering member 5, and the non-woven fabric having a lower rigidity is applied by an external force. It is easy to deform itself, and has less influence on the strip member 4. However, the strip member 4 is covered by the covering portion 2 and the covering member 5, so it is difficult to avoid 116819-980717.doc -13 - 1325330 from the influence of them, shape maintenance When the belt member only has the strip member 4, it deteriorates. According to the above results, it is clear that the member 4 is attached to the cover portion 2 in such a manner that it remains in a free state with the cover portion 2 and is covered by the cover member 5. On the other hand, even when an external force is applied, the shape maintainability can be achieved. That is, by fixing the π-shaped member 4 only to the cover member 5, the seal is made of the cover member 5, and the cover is attached to the cover 2 On the top, or the V-shaped member 4 is enclosed in the cover material 5, the test pen is added, ^, and the cover is removed. The installation structure between the two sides and the two are kept free, and the _, L pattern is good. The shape is maintained, whereby it is possible to effectively prevent the gap from being formed on both sides of the nose when the external force is applied to the mask 1.

如表2之實施例4及5所示，當遮蓋材5之剛度低於覆蓋部2 =，可獲得良好之形狀維持性。另一方面，如比較例3所示’ 若遮蓋材5之剛度高於覆蓋部2，則形狀維持性不良。根據以上可知，若使遮蓋材5之剛度低於覆蓋部2，則即使於施加外力時亦可獲得良好之形狀維持性。以上，對本發明之口罩1進行了說明，但本發明並不限定於該等，可實施各種變更。例如，將帶狀構件4固定於遮蓋材5時，若採用將帶狀構件4部分固定於遮蓋材5之安裝構造，則帶狀構件*受遮蓋材 5之衫響更小’可獲得更加良好之形狀維持性。例如，可採用=圖4⑷所例示’藉由熱炼勝6將帶狀構件*間歇性固定於遮蓋材5上之女裝構造，或者如圖彳⑻所示，藉由熱溶膠6 將帶狀構件4之—處固定於遮蓋材5上之安裝構造。如上所述，由於遮蓋材5形成為較帶狀構件4大一圈之長方形，故可易於進行使帶狀構件4駭於遮蓋材5上之後，再安裝於覆蓋部2之作業。或者可將帶狀構件 4設計為如圖5(a)〜(f)所例示之形 U6819-980717.doc :。圖5⑷係於與帶狀構件4之長度方向正交之方向上，設有複數個凹槽之帶狀構件4之例。由於該形狀之帶狀構件 4易於自凹槽部分蠻Α 曲’故可更容易地使其沿著配戴者之肌層塑性變形。若採用如圖5(b)〜π - ^ (d)所不、沿帶狀構件4之長度方向設置凹槽之形狀，於帶壯 . 於帶狀構件4之長度方向、以及寬度方向上均易於以凹槽為中心產4 ^ 產生邊形，故可更準確地模仿配戴者富As shown in Examples 4 and 5 of Table 2, when the rigidity of the covering member 5 was lower than that of the covering portion 2, good shape maintenance was obtained. On the other hand, as shown in Comparative Example 3, if the rigidity of the covering member 5 is higher than that of the covering portion 2, the shape retainability is poor. As described above, when the rigidity of the covering member 5 is made lower than that of the covering portion 2, good shape maintenance can be obtained even when an external force is applied. Although the mask 1 of the present invention has been described above, the present invention is not limited to these and various modifications can be made. For example, when the band member 4 is fixed to the cover member 5, if the attachment structure for fixing the band member 4 to the cover member 5 is employed, the band member * is less affected by the cover member 5, which is better. The shape is maintained. For example, the female structure in which the belt member* is intermittently fixed to the covering member 5 by the hot refining 6 can be employed as exemplified by Fig. 4 (4), or as shown in Fig. 8 (8), the ribbon is formed by the hot sol 6 The mounting structure of the member 4 is fixed to the covering member 5. As described above, since the cover member 5 is formed in a rectangular shape which is slightly larger than the band member 4, the operation of attaching the band member 4 to the cover member 5 can be easily performed after being attached to the cover member 5. Alternatively, the strip member 4 may be designed to have the shape U6819-980717.doc as illustrated in Figs. 5(a) to (f). Fig. 5 (4) is an example of a belt-shaped member 4 provided with a plurality of grooves in a direction orthogonal to the longitudinal direction of the belt-shaped member 4. Since the strip member 4 of this shape is easily bent from the groove portion, it can be more easily plastically deformed along the muscular layer of the wearer. If the shape of the groove is set along the longitudinal direction of the strip member 4 as shown in Figs. 5(b) to π - ^(d), the strip is strong. The length direction and the width direction of the strip member 4 are both It is easy to produce 4^ by the groove as the center, so it can more accurately imitate the wearer's rich
