Abstract

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.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A mask comprising: a main body and at least one attaching member; the main body being a flexible material and having at least one folded section at a middle portion, two short edges of the main body 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 having at least one horizontal, cut-open gap; wherein 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. 
     
     
         2 . The mask as claimed in  claim 1 , wherein the main body has a plurality of folded sections, and the two sealed edges of the main body both have a plurality of cut-open gaps. 
     
     
         3 . The mask as claimed in  claim 2 , wherein the cut-open gap of the main body is located beyond the folded section of the two sealed edges. 
     
     
         4 . The mask as claimed in  claim 2 , wherein the cut-open gap of the main body is located on the folded section of the two sealed edges. 
     
     
         5 . The mask as claimed in  claim 1 , wherein a length of the cut-open gap of the main body is at least half of a length of the sealed edge. 
     
     
         6 . The mask as claimed in  claim 1 , wherein a length of the cut-open gap of the main body is equal to a length of the sealed edge.
