Description of the Invention: [Technical Field of the Invention] The present invention relates to a mask having a leakage avoiding section. [Prior Art] A number of medical and safety hygienic masks are required to reduce the gap formed between the mask and the face as much as possible to reduce (in other words, improve) the external sputum rate. One indication. Thus, conventionally, a mask having a filter body that is made of a filter material and covers the mouth and nose of the wearer has been proposed and is disposed on the inner or peripheral edge of the mask body. In the venting section, when the mask is worn, the leakage section is prevented from coming into contact with the face surface to reduce the venting rate. For example, Japanese Patent No. 3,681,222 ("Patent Document") describes an ear attachment cord having a body portion covering a face and attached to the body portion, and two inner surfaces disposed on the face and the body portion. A mask of a breathable thin layer in the gap between the body portions on the side portions. Patent Document i 〇 states: "As shown in FIG. 2(A), a plurality of (or a single) elastic members 诸如 2 such as a rubber thread extending in the longitudinal direction are attached to one by, for example, stitching or adhesion, or the like. One edge portion llb of the substrate U." (paragraph [〇〇16]). Further, "as shown in Fig. 2(B), the opposite side edges of the edge portion 1 la of the substrate 11 attached to the elastic material 12 are also the same as the stitching knife 5 of the main body portion 2 The method is stitched together, and thus the edge portion 11a of the substrate n material is attached to the body portion 2. The portion of the substrate 11 that is sewn to the seam 卩 卩 5 is labeled 5a » at this time, execution The stitching is to produce a contraction (folding) 1 3 ' to shorten the length of the substrate 11 from H0 to H1. In addition, 154902. Doc 201200198, as shown in FIG. 2(C), the substrate U is folded back, and the edge portion 11b of the elastic member 12 covers the stitched partial side of the edge portion 丨la, and only The upper and lower edges 14, 14 of the edge portion lib are attached to the body portion 2 by sewing. Therefore, the support member 1 is formed into a three-dimensional collapsed shape, and when the inner side of the inner surface of the main body portion 2 is formed in a concave shape, the support member 10 will utilize the elastic member 12 (refer to FIG. 2(D) The elastic force is three-dimensionally projected from the inner surface of the main body portion 2 toward the surface of the face. In addition, Japanese Unexamined Patent Application Publication No. 2-7167346 ("Patent Document 2") describes a mask having a gas permeable thin layer which is formed by a ridge fold and a valley fold to form a collapse. An adhesive tape is formed on both side end portions of the collapse, and the collapsed wall system is joined to both side end portions, wherein the adhesive tape is thermally melted along the upper edge of the adhesive tape and A plurality of fusion notches are formed at designated intervals of the lower edge, and one end and the other end of each ear attachment cord are attached to the upper and lower edges of the adhesive tape. Patent Document 2 states that "first" the central portion of the upper edge portion 3 and the lower edge portion ^ of the mask is held and pulled in the up and down direction to expand the walls of the _2, and then the ear attachment cords 7, 7a is attached to both ears. Then, the hook portion 4 of the upper edge portion 3 and the lower edge portion 3a is formed to cover the nose and the chin. Because the upper and lower portions of the mask are fitted to the rafter And the chin 'and the side edge portions are curved at the junction between the splicing recesses 6, <food; etc.: the bulging portions 8, 8a and the surface is slightly deformed as if it exist - complex (four), # Produces a fit that closely matches the shape of the cheek (paragraph [0012J)" e, J54902. Doc 201200198 SUMMARY OF THE INVENTION One of the masks disposed on a medical or safety sanitary mask is preferably manufactured in a simple structure and inexpensively. When the mask is worn, the leakage avoidance section can be stably maintained. A state of contact with the surface of the face, and having a design that does not detract from the appearance of the mask when the mask is worn. The invention provides a novel mask having a leakage avoiding section. When the mask is worn, the avoidance leakage section is disposed between the mask body and the surface of the face 0, and the leakage rate can be effectively reduced. . A first aspect provides a mask comprising a mask body, one of the mask bodies disposed to avoid an escape section, and one of the masks that can be used to wear the mask, and the avoidance leaking section includes a configuration to be flat a first thin layer portion disposed on the mask body; the first thin layer portion being coupled to one of the mask body first connectors; configured to lie flat on the first thin layer portion a second thin layer portion; different from the first connecting member, the second connecting member 'which connects the second thin layer portion to the first thin layer portion; different from the first connecting member and the second connecting member a third connecting member having a function of connecting the first thin layer portion to the mask main body, connecting the second thin layer portion to the mask main body, and the function of the first thin layer portion At least one of the third connection=face|body and the first-thick layer part and/or between the first thin layer part and the second thin-layer part form a bag-folding configuration; and different In the first connecting member, the second connecting member and the third connecting member - Four connecting member which is connected to the belt of the second sheet portion. When the mask is worn on the wearer's face, as in the first aspect of the invention 154902. Doc 201200198 The mask is moved such that the mask body is separated from the first thin portion and the second thin portion, and the bag-folding configuration of the outer leakage section is maintained to maintain the connector, the second connector and the The three connectors are connected and opened, similar to an unfolded bag. Thus, the avoidance leaking section will protrude toward the outside of the unfolded bag-like mask body and will be present between the mask body and the wearer's face to contact the cheeks of the wearer. The wearing strap attached to the second thin portion is used to stabilize and maintain the open state of the folded configuration and the state in which the contact between the leaking section and the face is avoided when the 5 holster mask is worn. Therefore, with the mask of the first aspect of the invention, the leak between the mask body and the wearer's face is effectively avoided by the avoidance of the leaking section, and thus effectively reduces (in other words, improves) The venting rate and the venting rate are one of the protection functions. In addition, the outer casing section is prevented from extending from the mask body when the mask body is worn and has only a shape that substantially prevents a gap between the faces of the mask body and the wearer's face, and does not change the mask body. The shape and size, and thus the pattern that will not negatively affect the appearance of the mask. In addition, the avoidance leakage section has a very simple structure which is simply provided in a manner and can overlap the first thin layer portion and the second thin layer portion, and can be inexpensively configured in a simple configuration.
