Description

Reusable mask and manufacturing method thereof

[0001] The present invention relates to a mask, and more particularly, to a mask maximizing a user's wearing comfort by using a reusable fabric and a manufacturing method thereof.

Korean Patent Registration No. 10-2011242 (recyclable fine dust mask and its manufacturing method) discloses that foamed polyurethane fabric is first rolled to form and diffusely distribute irregular micropores while the gas contained in the cells explodes. And, by the secondary rolling operation, the micropores are passed through the outside air, and the polyurethane fabric having the micropores is sliced to a set thickness and then cut into a mask shape to manufacture a mask.

Since the mask manufactured in this way is a polyurethane fabric, it can be washed and reused.

By the way, such a conventional mask is made of a foamed polyurethane material and can be used repeatedly by washing, but due to the elasticity unique to the polyurethane material, the inner surface of the mask adheres to the wearer's nose and mouth, so the wearing comfort is greatly reduced.

That is, since the mask is pulled toward the ears in a state of being in close contact with the wearer's nose and mouth by the elastic force, breathing is not smooth, causing the wearer to feel very stuffy.

In order to manufacture a reusable mask according to the present invention, an upper mold 100 and a lower mold 200 are provided, and the upper mold 100 has a concave portion to follow the edge shape of the mask manufactured on its lower surface. 110 is formed, and the lower mold 200 is positioned below the upper mold 100.

Embossed portions 210 are formed in the lower mold 200 to correspond to the concave portions 110 of the upper mold 100.

That is, the embossed portion 210 is in a form that can be inserted into the intaglio portion 110, and heat of 160 to 200 ° C. is applied to the embossed portion 210 so that the mask fabric can be cut by heat It consists of

The embossed portion may be formed in the upper mold 100, and in this case, the concave portion may be formed in the lower mold 200.

The lower mold 200 is fixed, and the upper mold 100 is installed to be movable in the vertical direction by means of a cylinder. For this purpose, a plurality of intaglio parts 110 and embossed parts 210 may be provided.

The intaglio portion 110 has two stages with different intaglio heights, and the embossed portion 210 similarly protrudes in two stages. The intaglio portion 110 and the embossed portion 210 are pressed, respectively. It is composed of parts 111 and 211 and cutting parts 112 and 212.

When a fabric made of polyurethane foam in which a plurality of micropores are formed as a mask fabric is placed on the upper surface of the lower mold 200, the upper mold 100 descends and approaches the upper side of the lower mold 200.

At this time, the distance between the lower mold 200 and the upper mold 100 is slightly larger than the thickness of the foamed urethane fabric, and the embossed portion 210 of the lower mold 200 is the intaglio of the upper mold 100 as shown in FIG. Inserted into the portion 110, the cut portion 212 of the lower mold 200 comes into contact with the cut portion 112 of the upper mold 100, and is thermally cut into the left body form of the mask 500 as shown in FIG.

The cutting part 112 of the upper mold 100 is formed deeper and flatter than the pressing part 111, and the cutting part 212 of the lower mold 200 protrudes more than the pressing part 211, and its tip The portion is in contact with the cutting portion 112 of the upper mold 100 to cut the polyurethane fabric by heat.

In addition, the distance between the pressing part 211 of the lower mold 200 and the pressing part 111 of the upper mold 100 is formed narrower than the thickness of the polyurethane fabric, so that the edge 501 of the cut mask is pressed by heat. Let it finish by letting go.

That is, the edges of the main body of the mask 500 are thermally cut by the cutting parts 112 and 212, and at the same time, the edges 501 cut by the pressing parts 111 and 211 are thermally compressed, resulting in a clean finish.

At the same time, the left and right heat compression lines 520 and the top and bottom heat compression lines 530 are formed on the mask 500. is formed, so that when the mask 500 is thermally cut, the left and right heat compression lines 520 and the upper and lower heat compression lines 530 are formed at the same time.

The left and right heat compression lines 520 are formed in the left and right directions at the bridge of the nose when the wearer wears the mask to support the mask to maintain a three-dimensional effect, and the upper and lower heat compression lines 530 are formed in the vertical direction so that the mask has a three-dimensional effect It is supported to maintain, which will be described again later.

A left earring part 510 for hanging on the ear is formed on one side of the main body 500, and the end of the other side part is formed to have a round shape long in the vertical direction, and is thermally compressed along the circumference of the left earring part 510. A line 540 is formed.

When the left body of the mask 500 is formed in this way, it needs to be bonded to the right body. Since the right body is formed symmetrically with the left body, when the thermally cut left body is turned over to the right side, it can be used as the right body. .

Therefore, the left body and the right body are stacked in the same shape and then fixed to the lower joint mold 400 as shown in FIG. 4 to be positioned.

The lower bonding mold 400 is provided with an earring fixing part 420 to fix the stacked right body and left body, and has a round shape corresponding to it to join the left body and the other round part of the right body. An embossed portion 410 having is formed.

Therefore, after the earring parts 510 and 610 of the stacked left body and right body are inserted into the earring fixing part 420 and the rounded part is positioned above the embossed part 410, the upper joint mold 300 This descends to thermally bond the rounded portions to each other.

At this time, the upper joint mold 300 has a concave portion 310 having a corresponding shape at the same position as the embossed portion 410 of the lower joint mold 400, and the embossed portion 410 is thermally cut. It has a structure in which heat is applied for

As shown in FIG. 5, the rounded portion is thermally bonded to connect the other side portions of the left body 500 and the right body 600, that is, the portion in contact with each other as shown in FIG. A mask is formed.

At this time, the left and right heat compression lines 520 are formed on the part located on the nose of the wearer so that the mask adheres to the nose by folding. It can be easily folded in the direction, so that the upper part of the mask is supported so that it can be closely attached to the bridge of the nose.

The left and right heat compression lines 520 have a round shape from the upper side of the junction 700 of the mask, that is, the left body 500 and the right body 600, to both cheeks of the wearer's face symmetrically.

In addition, the upper and lower heat compression lines 530 are formed in the vertical direction of the mask, and the upper portion extends from the left and right ends of the left and right heat compression lines 520 to the lower side to be rounded, respectively, and the lower portion thereof is the joint portion It is formed to contact the lower side of 700.

Therefore, the round joint 700 allows the mask to protrude three-dimensionally forward from the area corresponding to the nose and mouth of the wearer, and the upper and lower heat pressing lines 530 stably support the three-dimensionally protruding shape. make it possible

That is, even if the wearer pulls the earring parts 510 and 610 to both sides while wearing the mask, the pulling force is reduced and dispersed in the upper and lower heat pressing lines 530 to minimize the pulling of the three-dimensionally protruding part forward, thereby providing a three-dimensional effect. that can retain its shape.

On the other hand, antibacterial pads may be attached to the inside of the mask, that is, the left body 500 and the right body 600. As shown in FIG. The antibacterial fabric portion 820 is attached to the upper surface of the tape 810 to form.

As shown in FIG. 8, in this antibacterial fabric portion 820, wefts are arranged at regular intervals in the horizontal direction, and warp yarns are arranged at regular intervals in the vertical direction. It is mainly arranged, and the yarn made of synthetic resin material is mainly arranged.

For example, only weft yarns may be arranged, or yarns made of synthetic resin material may be arranged alternately, and in the case of warp yarns, only yarns made of synthetic resin material may be arranged or yarns made of synthetic resin material and yarns may be arranged alternately. can

This is to make it easy to weave while maintaining sterilization and deodorization power by the copper component of the yarn. If is arranged only with yarns, when weaving, the weft and warp copper particles of the yarns rub against each other and fall off, thereby reducing the sterilizing power and increasing manufacturing cost.

However, by weaving in the form of a net with weft yarns mainly arranged and warp yarns mainly arranged synthetic resin yarns, there is no friction between the yarns, preventing copper particles from falling off.

Of course, both the weft yarn and the warp yarn can be manufactured only with yarn, and this sterilization pad layer 20 can be knitted in a cloth form rather than a net form.

In addition, it is possible to form the antibacterial fabric portion 820 in the form of a cloth by weaving or knitting by silver thread coated with silver particles on a thread made of a synthetic resin material rather than yarn, and the antibacterial fabric portion 820 by such a silver thread is also preferable. Preferably, silver yarn and synthetic resin yarn are arranged as weft and warp yarn, or only silver yarn is disposed, or silver yarn and synthetic resin yarn are alternately arranged, and even in the case of warp, only synthetic resin yarn is disposed, or Yarns and silver yarns made of synthetic resin may be alternately arranged.

It is preferable to use 70 denier for the yarn or silver yarn, and it is preferable to use 100 denier for synthetic resin yarn made of PE.

Here, denier is a unit representing the thickness of a thread, which is 450 m long and represents the thickness of a thread having a weight of 0.05 g.

Therefore, by forming the antibacterial fabric portion 620 with these yarns or silver yarns and synthetic resin yarns, it is harmless to the human body and can be manufactured relatively inexpensively.

When the antibacterial patch 800 fabric is completed, it is cut into a shape to be attached to the inner surface of the mask, which has a size and shape that can be attached to the inner wall surface of the three-dimensionally protruding part of the mask. it is desirable

That is, it has a size and shape attached to the inner surface from the upper and lower heat compression lines 530 to the junction 700 so that the mask has antibacterial and deodorizing functions.

The antibacterial patch 800 is detachable from the inside of the mask and can be exchanged after using for a certain period of time. If the antibacterial patch 800 is not attached correctly, it not only interferes with breathing, but also has the effect of the antibacterial function. and the wearability is significantly reduced.

Accordingly, as shown in FIG. 9 , display lines 550 are formed on the inner surface of the mask by thermal compression, and these display lines 550 are simultaneously formed when the left main body 500 is thermally cut.

Therefore, the wearer can attach the antibacterial patch 800 to the inside of the display line 500, and by attaching the antibacterial patch 800 to the optimal attachment position, smooth breathing and maximization of the antibacterial function, and comfort you can do good

Having described specific parts of the present invention in detail above, it is clear to those skilled in the art that these specific descriptions are only preferred embodiments, and the scope of the present invention is not limited thereby. something to do.
