Description

Three-dimensional face mask

This creation is about a mask, especially a three-dimensional mask.

When wearing a mask, in addition to the filtering performance of the mask material, you must also consider the tightness between the face and the mask when wearing the mask. If the tightness is insufficient, harmful substances may enter through the gap between the mask and the user's cheek. Inhaled by the mouth and nose of the user in the mask, the effect of protecting the user is lost.

Please refer to FIG. 1 to reveal the longitudinal section of a conventional planar mask, which is generally sewn from a non-woven laminate material, and includes a mask body 90, ear straps on both sides (not shown) and a bridge of the nose 91. The mask body 90 is mainly divided into at least one barrier layer 92 and a wrinkled portion 93. The nose bridge bead 91 is disposed in one of the folded edges of one end of the barrier layer 92, which can be improved by pressing the nose bridge bead 91 on the user's nose bridge The tightness between the mask body 90 and the user's face; the wrinkled portion 93 is used to increase the area where the mask body 90 covers the user's mouth and nose; during use, lightly press the nose bridge bead 91 to make the mask body 90 and the user's nose bridge close Then, press and hold the upper edge of the mask body 90, and stretch the wrinkled portion 93 to cover the lower jaw, thereby increasing the protective area of the mask body 90.

The wrinkled portion 93 of the conventional mask and the opening 94 are downward. Due to the characteristics of the fiber material, when the wrinkled portion 93 is stretched and unfolded, it has an elastic tendency to expand outward, and it is not easy to closely fit the user's face. Furthermore, since the curve of the human face is curved and not flat, the wrinkled portion 93 with the opening downward easily forms a gap between the cheeks of the user, and cannot provide good adhesion and coverage.

Furthermore, conventional masks have poor adhesion and coverage, so they are pressed against the bridge of the user's nose by means of the bridge 91 made of steel wire, which still has the effect of maintaining the tightness of the mask body 90 and the cheeks of both sides of the user. There are shortcomings, especially when the cover pressure when wearing is directly pressed to the highest nasal tip, and wearing the mask for a long time will cause user discomfort.

The purpose of this creation is to provide a flat three-dimensional mask with a wrinkled portion with an upward opening. When the wrinkled portion is stretched and unfolded, it has an elastic tendency to seal inward, making the edge of the mask body easier for the user The cheeks are tightly fitted, providing good adhesion and coverage.

The second objective of this creation is to provide a planar three-dimensional mask, which further has two side second pressing parts and/or two side third pressing parts which are hot-melt pressed on the wrinkled part, which have inward The curvature and curve of the side fold make the wrinkled portion stretch more inwardly and have an elastic tendency to seal inwards, so that the mask body provides better adhesion and covering properties.

Another purpose of this creation is to provide a planar three-dimensional mask, which has the advantages of both a planar mask and a three-dimensional mask without its shortcomings. Usually, the mask presents the shape of a flat mask, which has the advantages of small size after folding, which is easy to carry and store; when worn on the user's face, the mask shows the shape of a three-dimensional mask. The filtering effect is better than that of a plane mask, and it will not cover the mouth and nose. It has a larger breathing space. When worn for a long time, the comfort is better than the plane mask.

Another purpose of this creation is to provide a flat three-dimensional mask, which does not require a nose bridge bead, which not only simplifies the structure, but when wearing the mask for a long time, the user will not feel uncomfortable because the nose bridge bead presses the nose bridge .

The planar three-dimensional mask that can achieve the above-mentioned new purpose includes: a mask body made of laminated material, the mask body is mainly divided into a barrier layer and a wrinkled portion, the wrinkled portion has an upward opening, so that When the wrinkled portion is stretched and unfolded, it has an elastic tendency to seal inward; a two-sided ear strap provided on both sides of the mask body; and a second-side ear strap adjacent to the two-sided ear strap A pressing part, by which the mask body and the two side hanging ear straps are integrated into one.

In a preferred embodiment of the present invention, it further has two side second nip portions symmetrically arranged on the wrinkled portion, and the two side second nip portions have an arc bent inward.

In a preferred embodiment of the present invention, the second pressing portions on the two sides are one of arcs, rhombuses, and other geometric shapes.

In a preferred embodiment of the present invention, the second-side second pressure-bonding portion is hot-melt pressure-bonded to the wrinkled portion; the hot-melt pressure-bonding is particularly preferably ultrasonic welding.

In a preferred embodiment of the present invention, the third crimping portion is symmetrically disposed on the corrugated portion, and the third crimping portion on both sides has an arc bent inward.

In a preferred embodiment of the present invention, the third pressing portions on the two sides are one of arcs, rhombuses, and other geometric shapes.

In a preferred embodiment of the present invention, wherein the third pressure-bonding parts on the two sides are crimped on the wrinkled part by heat fusion; the heat fusion crimping is particularly preferably ultrasonic welding.

Please refer to Fig. 2 and Fig. 3 at the same time, the planar three-dimensional mask provided by this creation mainly includes: a mask body 10 made of laminated materials, the mask body 10 is mainly divided into a barrier layer 11 and a wrinkle Folded portion 12, the wrinkled portion 12 has an upward opening 13, so that when the wrinkled portion 12 is stretched and unfolded, it has an elastic tendency to close inward, making the mask body 10 easier to closely fit the user's cheek Provides good adhesion and coverage; a two-sided ear straps 14 provided on both sides of the mask body 10; and a two-side first press-fit portion adjacent to the two-sided ear straps 14 15. By pressing the mask body 10 and the pre-formed body of the two side ear straps 14 into one.

In a preferred embodiment of the present invention, the second crimping portion 16 is disposed on the corrugated portion 12 and is symmetrical to each other. The second crimping portion 16 on the two sides has an arc bent inward When the crumpled portion 12 is stretched and unfolded, it has an elastic tendency of inward adhesion, and the mask body 10 provides a better adhesion and covering properties. The two-side second nip portion 16 is located on the inner side of the two-side first nip portion 15.

The second compression portions 16 on both sides are crimped to the corrugated portion 12 by hot melt; the hot melt crimping is particularly preferably ultrasonic welding.

Please refer to FIG. 4, the planar three-dimensional mask provided by the present creation has a wrinkled portion 12 with an opening 13 upward, and two side second press-fitting portions 16 that are hot-melt pressed onto the wrinkled portion 12, The second pressing portion 16 on both sides has an arc and a curve bent inward; therefore, when the wrinkled portion 12 is stretched and unfolded, it has an elastic tendency to seal inward, making the edge of the mask body 10 easier to The user's cheeks fit snugly, providing good adhesion and coverage. As shown in FIG. 2, the mask body 10 usually takes the form of a flat mask, which has the advantages of small size after folding, which is convenient for carrying and storage. As shown in FIG. 4, when the mask is worn on the face of the user, the wrinkled portion 12 swells upwards, so that the mask body 10 assumes the shape of a three-dimensional mask, and the filtering effect of particles is better than that of a flat mask. Moreover, the nose bridge 20 of the user is not covered, and there is a large breathing space. When worn for a long time, the comfort is better than that of a flat mask.
