Description

Facial mask

The present invention relates to a mask.

According to the fact that the new crown pneumonia and flu epidemics continue to spread around the world, the populations of various countries are becoming more and more accustomed to wearing masks, and the demand for masks is also increasing, which has caused a large number of resources and manpower to invest in the production of masks. And research and development. Among them, the original system of the conventional mask is made up of multiple layers of cloth materials. However, the anti-slip function of the conventional mask body is not good, which easily makes it difficult for users to hold and take off. In addition, the multi-layer cloth material is easy to separate from each other during use, which reduces the function of isolating pollutants in the air. There is an urgent need for improvement. The shortcomings.

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

The main purpose of the present invention is to provide a mask that has strong structural strength to avoid separation of the inner layer, middle layer and outer layer of the mask. In addition, the body has a better anti-slip function and is easy to hold for taking off.

To achieve the above objective, the present invention provides a mask, which includes a body. The body includes an outer layer, a middle layer and an inner layer that are superimposed on each other. The outer layer, the middle layer and the inner layer are welded to form a plurality of welding structures, and the welding structures are arranged in an asymmetrical shape.

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

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

The body 1 includes an outer layer 11, a middle layer 12, and an inner layer 13, which are superimposed on each other. The outer layer 11, the middle layer 12, and the inner layer 13 are welded to form a plurality of welding structures 14 Symmetrical shape arrangement. Preferably, the outer layer 11 is made of a non-absorbent non-woven material to isolate external droplets; the middle layer 12 is made of melt-blown non-woven material to filter dust and germs, and the inner layer 13 is made of a water-absorbent non-woven material to improve wearing comfort Spend.

Thereby, when dust from the outside touches the surface of the main body 1, since the welding structures 14 are arranged in an asymmetrical shape, it can be avoided that when the dust falls from one of the welding structures 14 to the adjacent other In the welding structure 14, therefore, the present invention can effectively prevent dirt and bacteria from remaining on the surface of the main body 1.

In detail, in this embodiment, the projections of the two partially adjacent welding structures 14 along the first direction L1 do not completely overlap, and the projections of the two partially adjacent welding structures 14 along the second direction L2 are not completely overlapped in this embodiment. They are not completely overlapped, which can effectively make the two adjacent welding structures 14 not symmetrical in the first direction L1 and the second direction L2, so as to effectively provide the user with a special touch and avoid dirt. And bacteria remain on the surface of the body 1.

It is worth mentioning that each of the welding structures 14 is elongated, which can greatly increase the welding area of each of the welding structures 14 to increase the bonding strength of the outer layer 11, the middle layer 12 and the inner layer 13. In addition, it can make When the user takes the main body 1 by touching the welding structures 14 to increase the friction, it is not easy to slip off with the fingers, so it is more convenient to take off.

Specifically, the body 1 defines a first direction L1 and a second direction L2 perpendicular to each other. The body 1 includes two long sides 15 extending along the first direction L1 and two short sides extending along the second direction L2. On the side 16, the welding structures 14 are arranged at least on the two short sides 16 and one long side 15.

Wherein, each of the welding structures 14 is long linear, which can greatly increase the welding area of each of the welding structures 14 to improve the bonding strength of the outer layer 11, the middle layer 12, and the inner layer 13, and also allow the user to hold When the main body 1 is taken out, the frictional force is increased by touching the welding structures 14 and it is not easy to slip off with the fingers, so it is more convenient to take off.

Furthermore, some of the welding structures 14 are enclosed in a closed shape, so that each of the welding structures 14 can form a pattern to have a visual effect, thereby increasing the consumer's willingness to buy. In this embodiment, it is surrounded in a circle shape. As shown in FIG. 5, in the second embodiment of the present invention, each of the welding structures 14A can also be star-shaped, or in the third embodiment as shown in FIG. 6, each of the welding structures 14B is in the shape of an animal. Improve the visual effect and increase the welding area of each welding structure 14B.

Preferably, the welding structures 14 are formed by stamping welding. The welding structures 14 form a plurality of grooves 31 on at least one side of the main body 1, and at least one side of the main body 1 is adjacent to two adjacent grooves. A convex portion 32 is formed between 31. The end of each convex portion 32 away from the middle layer 12 includes an arc protrusion 321 and two arc recesses 322. The arc protrusion 321 is connected between the two arc recesses 322. When the protrusion 32 only touches the arc protrusion 321, it has a better tactile feel to improve grip comfort and anti-slip properties. In addition, the two arc recesses 322 have a lower relative height than the arc protrusion 321, which is better Prevent falling dust from sticking to the surface, so it can avoid dirt and bacteria remaining on the surface.

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 a plurality of grooves can be formed on both sides of the main body 1 The groove 31 and the plurality of protrusions 32 are so that both sides have the anti-slip function.

Parts of the main body 1 are flexibly stacked along the second direction L2 to form a plurality of folding structures 17, and some of the welding structures 14 are arranged on the plurality of folding structures 17 (as shown in FIG. 4), so that the grooves 31 The depth is relatively deep, which means that the protrusions 32 and the grooves 31 have a large drop, and it is not easy to slip off when the user holds the folding structures 17, and the folding structures 17 are not easy to slip off. Loose.

Some of the welding structures 14 are provided on one long side 15, the other long side 15 is provided with a bendable metal strip 21, one of the inner layer 13 and the outer layer 11 is provided with two ear bands 22, and part of The welding structures 14 are arranged on the two ear bands 22 so that each of the ear bands 22 can have a larger welding area to be combined with the main body 1 so as to prevent the ear bands 22 from being separated from the main body 1.

In summary, the mask of the present invention, when dust from the outside touches the surface of the body, since the welding structures are arranged in an asymmetrical shape, it can prevent the dust from falling into the neighboring area when the dust falls from one of the welding structures. In another welding structure, therefore, the present invention can effectively prevent dirt and bacteria from remaining on the surface of the body.
