Description

Foldable three-sided three-dimensional mask

This creation relates to a three-dimensional mask, especially a foldable three-sided three-dimensional mask.

Referring to FIG. 6 , a mask commonly used in the market is a planar wrinkle mask having a mask body 61 , two straps 62 connecting the mask body 61 , and a bridge of the nose disposed on the mask body 61 . Pressing strip 63. In order to increase the expiratory space of the planar wrinkle mask, the mask body 60 is laterally folded to form a plurality of wrinkles 611.

However, the plurality of wrinkles 611 formed on the mask body 60 can reduce the surface flatness of the prior art planar wrinkle mask, making it difficult for the wearer to fold the flat wrinkle mask into a smaller structure, which is disadvantageous. It is carried out on the outside; and the prior art flat wrinkle mask needs to be provided with a protective bag on the outside to prevent the inner surface of the contact with the mouth and nose from being exposed to dust or bacteria during carrying.

Furthermore, by using the wrinkle portion 611 to increase the expiratory space, the mask body 61 needs to be folded at equal intervals from each other, so that the difficulty of manufacturing the prior art planar wrinkle mask is increased, and the wearer wears the prior art. In the case of a planar wrinkle-type mask, the outer surface of the mask body 61 may arbitrarily form a messy and uneven surface, and the appearance of the flat wrinkle-type mask may be reduced.

In view of the shortcomings of the prior art, the main purpose of the present invention is to provide a foldable three-sided three-dimensional mask capable of producing a foldable three-sided three-dimensional mask with a large exhalation space in a relatively simple process, and at the same time Improve its portability, health and safety.

Preferably, an upper arc bonding wire and an upper outer edge bonding wire are disposed between the upper mask portion and the symmetric mask portion, and the upper arc bonding wire passes through the right bending line of the symmetric mask portion. The upper edge extends toward the left bend line extending from the right edge of the symmetric mask portion through the upper edge to the left edge. According to this, the upper mask portion and the symmetric mask portion can be The upper circular arc wire and the upper outer edge bonding wire are tightly joined.

Preferably, a lower arc bonding wire and a lower outer edge bonding wire are disposed between the lower mask portion and the symmetric mask portion, and the lower arc bonding wire passes through the lower bending line of the symmetric mask portion. The edge extends toward the left bend line that extends from the right edge of the symmetric mask portion through the lower edge to the left edge. Accordingly, the lower mask portion and the symmetric mask portion can be tightly joined by the lower arc bonding wire and the lower outer edge bonding wire.

Preferably, the length of the left bending line is the same as the length of the right bending line, so as to ensure that the internal exhalation space formed by the three-faceted three-dimensional mask of the present fold is located at the mouth of the wearer, and At the same time maintain its aesthetics.

Preferably, the foldable three-sided three-dimensional mask has a nose bridge bead disposed transversely to the upper mask portion for the foldable three-sided three-dimensional mask to fit snugly against the nose bridge of the wearer.

According to the present invention, the upper sheet body, the lower sheet body, the upper mask portion and the lower mask portion each have an inner surface and an outer surface opposite to the inner surface, the symmetric mask portion being aligned with the upper edge and After the lower edge is folded, the inner surface of the upper mask portion is in contact with the inner surface of the upper sheet body, and the inner surface of the lower mask portion is in contact with the inner surface of the lower sheet body, and the upper mask portion is The outer surface is in contact with the outer surface of the lower mask portion. Accordingly, the three-sided three-dimensional mask that can be folded can have good hygiene and safety.

According to the present creation, the foldable three-sided three-dimensional mask has the following advantages: (1) The creation of the symmetrical mask portion is outwardly arched by the left bend line and the right bend line, and the foldable three-sided three-dimensional mask is added. Exhale space, so The present invention does not need to fold the mask body at equal intervals to form a plurality of wrinkles as in the prior art planar wrinkle mask, thereby simplifying the process of the foldable three-sided three-dimensional mask and improving the appearance thereof; (2) The symmetrical mask portions are symmetrical to each other and are composed of an upper sheet and a lower sheet having the same shape, and the upper and lower mask portions have the same shape as the upper sheet and the lower sheet, respectively, so the creation can be folded.
