The present invention relates to a facial respiratory mask.
According to the conventional mask structure, please refer to
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'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.
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.
Please refer to
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
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.
