Description

Facial mask

The present invention relates to a mask.

Press, in response to the continuous spread of new coronary pneumonia and influenza in the world, the population of various countries is more and more accustomed to wearing masks, and the demand for masks is also increasing, causing a large number of resources and manpower to invest in the production of masks. and R&D. Among them, the basic system of the conventional mask is formed by stacking multiple layers of cloth. However, the anti-slip function of the conventional mask body is not good, and it is easy for the user to take off and take off easily. In addition, the multiple layers of cloth are easily separated from each other during use, which reduces the function of isolating pollutants in the air, and there is an urgent need for improvement. shortcomings.

Therefore, it is necessary to provide a novel and progressive mask to solve the above problems.

The main purpose of the present invention is to provide a mask, which can have strong structural strength to prevent the inner layer, middle layer and outer layer of the mask from being separated from each other. In addition, the main body has a better anti-slip function and is easy to hold for taking off and wearing.

In order to achieve the above purpose, the present invention provides a mask, comprising a body. The main body includes an outer layer, a middle layer and an inner layer which are superimposed, and the peripheral edges of the outer layer, the middle layer and the inner layer are welded together to form a plurality of welded structures, and each of the welded structures is in the shape of a long line.

The following examples are only used to illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention, and are described together first.

Please refer to FIGS. 1 to 4 , which show the first preferred embodiment of the present invention. The mask of the present invention includes a body 1 .

The main body 1 includes an outer layer 11 , a middle layer 12 and an inner layer 13 that are superimposed on each other. The outer layer 11 , the middle layer 12 and the inner layer 13 are fused together to form a plurality of welding structures 14 , and each of the welding structures 14 is long line. Preferably, the outer layer 11 is a non-woven material that does not absorb water to isolate external droplets; The layer 12 is made of melt-blown non-woven fabric to filter dust and germs, and the inner layer 13 is made of water-absorbent non-woven fabric to improve wearing comfort.

Therefore, since each of the welding structures 14 is elongated, the welding area of each of the welding structures 14 can be greatly increased, so as to improve the bonding strength of the outer layer 11 , the middle layer 12 and the inner layer 13 . When the body 1 is taken, the frictional force is improved by touching the welding structures 14, and it is not easy to slip off relative to the fingers, so it is more convenient to take off and put on.

Specifically, the body 1 defines a first direction L1 and a second direction L2 that are perpendicular to each other, and the body 1 includes two long sides 15 extending along the first direction L1 and two short sides extending along the second direction L2 Sides 16 , some of the welding structures 14 are disposed on at least the two short sides 16 . In this embodiment, some of the welding structures 14 are provided on one of the long sides 15 , the other long side 15 is provided with a metal strip 21 that can be bent, and one of the inner layer 13 and the outer layer 11 is provided with two The ear straps 22, some of the welding structures 14 are provided on the two ear straps 22. Since the welding structures 14 are elongated, each of the ear straps 22 can have a larger welding area to be combined with the body 1, so as to avoid Each of the ear straps 22 is separated from the main body 1 .

Specifically, the welding structures 14 are formed by stamping welding, and the welding structures 14 form a plurality of grooves 31 on at least one side of the body 1 , and at least one side of the body 1 is adjacent to two adjacent grooves. A convex portion 32 is formed between 31 . In this embodiment, the grooves 31 and the protrusions 32 are respectively formed on a side of the outer layer 11 away from the middle layer 12 and a side of the inner layer 13 away from the middle layer 12 , so that the two sides of the main body 1 are formed. A plurality of the grooves 31 and a plurality of the convex portions 32 are formed, so that both sides have the anti-slip function.

Wherein, one end of each convex portion 32 away from the middle layer 12 includes an arc convex 321 and two arc concave 322. The arc convex 321 is connected between the two arc concave 322. When the user touches the convex portion 32, only the Contact with the arc convex 321, so it has a better tactile feeling to improve grip comfort and slip resistance, and the two arc concave Because the relative height of 322 is lower than that of the arc protrusion 321 , it can prevent dust from adhering to the surface, and thus can prevent dirt and bacteria from remaining on the surface.

It is worth mentioning that parts of the body 1 are flexibly folded and stacked along the second direction L2 to form a plurality of folded structures 17 , and some of the welding structures 14 are provided on the plurality of folded structures 17 (as shown in FIG. 4 ), which can be The depth of the grooves 31 is relatively deep, which means that there is a large drop between the protrusions 32 and the grooves 31, and it is not easy to slip off when the user holds the folding structures 17, and each The folded structure 17 is not easily released.

Wherein, at least some of the welding structures 14 are inclined to the first direction L1 and the second direction L2. In this embodiment, the welding structures 14 are inclined to the first direction L1 and the second direction L2, so as to The welding structures will overlap along the extending directions of the first direction L1 and the second direction L2, so that the bonding strength of the outer layer 11, the middle layer 12 and the inner layer 13 can be extremely high, so as to improve the safety of the mask. Durability.

Referring to FIG. 5 , compared with the above-mentioned first embodiment, in the second embodiment of the present invention, the welding structures 14A are parallel to the first direction L1 and disposed on the two short sides 16 . Some of the welding structures 14B are disposed on the two long sides 15 parallel to the second direction L2, and the welding structures 14A, 14B can be densely distributed on the two short sides 16 and one of the long sides 15 to improve the bonding strength .

Referring to FIG. 6 , compared with the second embodiment described above, in the third embodiment of the present invention, the welding structures 14C are parallel to the first direction L1 and disposed on the long side 15 , so that the welding structures can be 14C extends completely along the first direction L1 to the long side 15, and the long side 15 is less likely to be subjected to a force along the first direction L1 to separate the outer layer, the middle layer and the inner layer.

Referring to FIG. 7 , compared with the third embodiment described above, in the fourth embodiment of the present invention, the welding structures 14D are parallel to the second direction L2 and disposed on the two short sides 16 , so that the welding structures 14D can be welded together. The structure 14D extends completely along the two short sides 16 along the second direction L2, and the two short sides 16 are less likely to be subjected to force along the second direction L2 to separate the outer layer, the middle layer and the inner layer.

To sum up, the mask of the present invention, because each welding structure is elongated, can greatly increase the welding area of each welding structure, so as to improve the bonding strength of the outer layer, the middle layer and the inner layer. When taking the body, the frictional force is improved by touching the welding structures, and it is not easy to slip off relative to the fingers, so it is more convenient to take off and put on.
