Title: Mask

Description:
BACKGROUND OF INVENTION 
     Field of Invention 
     The present invention relates to a facial respiratory mask. 
     Description of Related Art 
     According to the conventional mask structure, please refer to  FIGS. 6, 7 , and  8 . The mask  20  is a flat mask and the mask  20  is folded to have a plurality of the folded sections  21 . The folded sections  21  of the mask  20  can be stretched and unfold and the edges of the two sides of the mask  20  are thermally pressed to form two edge sealing portions  22 . The two edge sealing portions  22  also secure the folded section  21  on both sides of the mask  20 . When the folded section  21  of the mask  20  is stretched and unfold, the two short sides of the mask  20  are secured by the edge sealing portion  22  to avoid being stretched and unfolded, and the mask  20  further includes ear loops  23  attached to the two edge sealing portions  22 . 
     When the conventional mask  20  is used, the folded sections  21  are first stretched out and placed on the outside of the mouth and nose, and the ear straps  13  are worn on both ears, so as to isolate the outside air to prevent pollution and mouth spit transmission. However, since the two ends of the ear loop  23  are connected to the upper and lower positions of the edge sealing portion  22 , when the mask  20  is worn, the edge sealing portion  22  is only pulled at the upper and lower positions because of the ear loop  23 , the middle position of the edge sealing portion  22  is squeezed and deformed. As a result, the edges on both short ides of the mask  20  cannot firmly cover the user&#39;s cheek skin, thereby causing an opening  24  is formed between the short edges of the mask  20  and the cheeks, which greatly reduces the covering effect of the mask  20 , so that bacteria and viruses in the air can easily invade the inside of the mask  20  from the openings  24  on both sides. 
     Therefore, it is desirable to provide a facial respiratory mask to mitigate and/or obviate the aforementioned problems. 
     SUMMARY OF INVENTION 
     An objective of present invention is to provide a facial respiratory mask, which is capable of improving the above-mention problems. 
     In order to achieve the above mentioned objective, a mask has a main body and at least one attaching member. The main body is a flexible material and has at least one folded section at a middle portion. Two short edges of the main body are formed by a hot melt press process to provide two sealed edges for securing the folded sections and the attaching member. The two sealed edges have at least one horizontal, cut-open gap. The cut-open gap allows the two sealed edges to form at least one overlapped portion and the two sealed edges are respectively curved as an arced edge. The overlapped portions increase the sealing effect of the two sealed edges, which greatly improves the covering effect of the main body, and indeed prevents bacteria and viruses in the air from invading from both sides of the main body to help improve the safety and the protection effect of the main body. 
     Other objects, advantages, and novel features of invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENT 
     Please refer to  FIGS. 1 and 2 . A mask comprises a main body  10  and at least one attaching member  13 . The main body  10  is a flexible material and has at least one folded section  11  at a middle portion, two short edges of the main body  10  are formed by a hot melt press process to provide two sealed edges  12  for securing the folded sections  11  and the attaching member  13  such as a pair of ear loops, and the two sealed edges  12  restrict the expansion of the short edge of the main body  10 . The two sealed edges  12  has at least one horizontal, cut-open gap  121  wherein the cut-open gap  121  allows the two sealed edges  12  to form at least one overlapped portion  122  and the two sealed edges  12  are respectively curved as an arced edge. 
     The main body  10  is composed a plurality of woven materials edged by the hot melt press and cut processes to form the two sealed edges  12 . During the hot melt press and cut processes, the two sealed edges  12  of the main body  10  are cut to form the cut-open gaps  121  with predetermined distance without affecting the protection effect of the main body  10 . A length of the cut-open gap  121  of the main body  10  is at least half of a length of the sealed edge  12 , or a length of the cut-open gap  121  of the main body  10  is equal to a length of the sealed edge  12 . Moreover, the two sealed edges  12  have a plurality of cut-open gaps  121 , and the cut-open gaps  121  are formed beyond the folded section  11  of the two sealed edges  12  or cut-open gaps  121  are formed on the folded section  11  of the two sealed edges  12 . 
     For the actual state of its structure, please refer to  FIGS. 1, 2, 4, and 5 . The main body  10  also includes the ear straps  13  attached to the two sealed edges  12 , the folded section  11  of the main body  10  is first stretched out and placed to cover the mouth and nose, and then the ear straps  13  are placed on both ears through, to achieve the purpose of isolating external air pollution and preventing the infection of mouth foam. The two ends of the ear straps  13  are respectively connected to the upper and lower positions of the sealed edge  12 , so that when the main body  10  is worn, the sealed edge  12  will only be pulled at the upper and lower positions due to the ear straps  13 , and with the cut-open gaps  121 , the two sealed edges  12  are retracted and interlaced to form at least an overlapped portion  122  and forms an arc shape corresponding to the size of the face. Therefore, the two sealed edges  12  stay close to the skin, and the overlapped portion  122  formed by the cut-open gap  121  increases the sealing effect of the two sealed edges  12 , which greatly improves the covering of the main body  10  and indeed prevents bacteria and viruses in the air from invading both sides of the main body  10 . 
     With the structure of the above specific embodiment, the following benefits can be obtained: The sealed edge  12  of the main body  10  has at least one cut-open gap  121 , when the two sealed edges  12  are pulled by the ear straps  13 , the cut-open gaps  121  make the two sealed edges  12  to be retracted and interlaced to form at least an overlapped portion  122 , so that the two sealed edges  12  can be more fitted on the cheek skin. At the same time, the overlapped portions  122  formed by the cut-open gaps  121  increase the sealing effect of the two sealed edges  12 , which greatly improves the covering effect of the main body  10 , and indeed prevents bacteria and viruses in the air from invading from both sides of the main body  10  to help improve the safety and the protection effect of the main body  10 . 
     In addition, the design of the cut-open gap  121  of the main body  10  helps to improve the variability of the two sealed edges  12 , so that the two sealed edges  12  can be properly retracted according to the different face shapes, while maintaining the covering effect of the two sealed edges  12 , which is suitable for various face shapes. 
     Although the present invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of invention as hereinafter claimed.
