Description

Flat mask structure

This creation is about a mask structure, especially a flat mask structure with covering properties.

Press, the structure of a conventional mask, please refer to Figures 6, 7, and 8. The mask 20 is a flat mask. The mask 20 is folded with a plurality of folding parts 21, and the mask 20 is folded through the folding parts 21. The mask 20 is stretched and unfolded, and the edges on both sides of the mask 20 are then heat-compressed to form two edge-sealing parts 22. The two edge-sealing parts 22 are used to form the mask 20 on the folds 21 on both sides of the mask and are fixed together , When the folding part 21 of the hood 10 is stretched and used, its two sides can pass through the edge sealing part 22 to avoid being stretched and unfolded, and the mask 20 further includes welding to the two edge sealing parts 22 The upper ear strap 23 completes a mask structure.

When the conventional mask 20 is used, the folded part 21 is first stretched and stretched to cover the mouth and nose, and then worn on both ears through the ear straps 23, so as to isolate external air pollution and prevent the mouth. The purpose of foam infection, but since the two ends of the ear strap 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 will be affected by the ear strap. 23 only pulls at the upper and lower positions, causing the mid-section of the edge-sealing portion 22 to be squeezed and expanded and deformed. As a result, the edges of both sides of the mask 20 cannot be reliably adhered to the user’s cheeks, and the mask An opening 24 is created between the edges of both sides of the mask 20 and the cheeks, which greatly reduces the covering effect of the mask 20 and makes the air Bacteria and viruses are still easy to invade the inside of the mask 20 from the openings 24 on both sides, which affects the wearing effect of the mask 20, lacks practicability, and needs improvement.

In view of this, the creator has been engaged in the manufacturing, development and design of related products for many years, and after detailed design and careful evaluation for the above goals, he finally got a practical creation.

The technical problem to be solved by this creation is to provide a flat mask structure in response to the above-mentioned shortcomings in the prior art.

The above-mentioned mask structure includes a mask body, which is a flat mask, and is folded at the middle section with at least one folding part for stretching and unfolding the mask body, and the two side edges of the mask body are tied The hot-melt pressing forms two bonding edges, and then the mask body is formed on the folded parts of the two side edges to be bonded and fixed, and the two bonding edges prevent the two side edges of the mask body from being stretched and unfolded, and the mask body Second, the bonding edge is provided with continuous wavy concave and convex arcs from top to bottom.

Preferably, the depth of the concave arc portion of the mask body is within half of the width of the hot-melt pressing of the bonding edge.

Preferably, the mask body further includes two ear straps welded to the two fitting edges.

Preferably, the earband is a string with elasticity.

Preferably, the ear straps are wide non-woven ear straps.

Preferably, at least one long side of the ear band is provided with a plurality of inner concave arcs and outer convex arcs in a continuous wave shape.

Preferably, the two long sides of the ear band are symmetrically provided with a plurality of inner concave arcs and outer convex arcs in a continuous wave shape.

Compared with the effect of the prior art: when the mask body is worn, the fitting edges will form a wrinkle shape due to the upper and lower positions of the ear strap being pulled, at this time, it can pass through the concave arc and the convex arc The drop formed between the parts allows the two fitting edges to be curved and deformed, and then the curve corresponding to the size of the face forms an arc shape. At the same time, the arc edges of the concave and convex arc parts are used to lift the two fitting edges to contact The comfort of the skin makes the fitting edge more comfortable to the cheek skin, which greatly improves the covering of the mask body when wearing it, and indeed prevents bacteria and viruses in the air from invading from the edges of the mask body on both sides. The purpose is to help improve the safety and protective effect of the mask body.

In order to enable your reviewer to have a further understanding and understanding of the purpose, features and effects of this creation, please cooperate with the following [Schematic Description] as detailed below:

First, referring to Figures 1 and 2, a flat mask structure includes a mask body 10. The mask body 10 is a flat mask and is folded at the middle section with at least one folding part. 11. Unfold the mask body 10 for stretching, and the two side edges of the mask body 10 are heat-melted and pressed to form two bonding edges 12, and then the mask body 10 is formed on the folds 11 of the side edges. The two fitting edges 12 prevent the two side edges of the mask body 10 from being stretched and unfolded, and the two fitting edges 12 of the mask body 10 are provided with continuous wavy concave arcs from top to bottom. 121 and the convex arc portion 122, the depth of the concave arc portion 121 is within half of the width of the hot-melt pressing of the fitting side 12, and the mask body 10 further includes two ear straps 13 welded to the two fitting sides 12 , The ear strap 13 is a string with elasticity.

For the actual use of the structure, please refer to Figures 1, 2 and 3. The mask body 10 first stretches the folding portion 11 and rests on the outside of the mouth and nose, and then passes through the ear straps 13 Wear on both ears to use the mask body 10 to achieve the purpose of isolating external air pollution and preventing mouth foam infection, because the two ends of the ear band 13 are connected to the upper and lower positions of the fitting edge 12 respectively At this time, when the mask body 10 is worn, the fitting edge 12 will form a wrinkle shape due to the upper and lower positions of the ear strap 13 being pulled. At this time, it can pass through the concave arc 121 and the convex The drop formed between the arcs 122 is used for the arc deformation of the two mating edges 12, and then the curve corresponding to the size of the face forms an arc shape, and the arc edges of the concave and convex arcs 121, 122 are used for lifting Second, the comfort of the fitting side 12 in contact with the skin, so that the second fitting side 12 can be more conformable to the cheek skin, greatly improving the covering of the mask body 10 when wearing, and indeed prevent bacteria and viruses in the air The purpose of intruding from the edges of both sides of the mask body 10 helps to improve the safety and protection effect of the mask body 10.

Furthermore, the ear strap 13 can be a wide version of non-woven ear straps. As shown in Figure 4, at least one long side of the ear strap 13 is provided with a plurality of inner concave arcs 131 and outer portions in a continuous wave shape. The convex arc 132, or the symmetrical long sides on both sides, are provided with a plurality of concave arcs 131 in a continuous wave shape and The outer convex arc 132, as shown in Fig. 5, uses the inner concave arc 131 designed on the long side to achieve elastic stretching of the ear strap 13, which improves the applicability of the mask body 10 while maintaining the wearing The comfort level.

In summary, this creation has indeed achieved a breakthrough structural design, and has improved new content, while at the same time it can achieve industrial utilization and progress. Moreover, this creation has not been seen in any publications, and it is also novel.
