Description

Mask with adjustable the length of strap {Mask with adjustable the length of strap}

The present invention relates to a mask capable of adjusting the length of a string to greatly increase the effect of quarantine or dust prevention by increasing the adhesion of the mask to the wearer's face by allowing the length of the ear strap provided on the mask to be adjustable. .

Wearing a quarantine mask has become very important due to the recent epidemic of viruses transmitted through droplets, and wearing such a quarantine mask has been proven to be a very effective means to block the spread of viruses.

In addition, it is very effective to wear a dust mask to block fine dust.

In particular, in the case of adjusting the length of the string for hanging ears provided in the mask, the mask is brought into close contact with the wearer's face to increase the quarantine or dustproof effect. As an example of the prior art for adjusting the length of the string, Registered Patent No. In No. -1985741 (mask strap adjusting device), it has a column shape with a through hole formed inside in the longitudinal direction so that the strap can pass through, and on one side there is a side hole for fixing or releasing the strap depending on the position where the strap passes. and insertion pillars are formed on both sides of the other side with respect to the center so that the mask can be inserted into the insertion groove formed on the side of the mask and fixed to the mask, and the insertion pillar is inserted into the mask insertion groove at the top of the insertion pillar. After being formed, the hooking head is formed so that it does not fall easily, and a mask strap adjusting device formed of a plastic material different from the material of the mask has been proposed.

However, according to this prior art, since the strap adjusting device must be injection molded from a plastic material, there is a problem in that the manufacturing cost increases accordingly, and also, when manufacturing the mask, a groove for insertion is provided so that the strap adjusting device can be inserted into the mask separately. After forming, since the string adjusting device in which the string is inserted into the groove for insertion must be fixed, the manufacturing process is very complicated, resulting in a significant decrease in productivity.

In addition, since the strap adjusting device made of such a plastic material is fixed to both sides of the mask, there is also a problem that prevents the mask from being in close contact with the wearer's face.

As shown in FIG. 1, the present invention is composed of a body portion 100 and left and right hanging straps 300 and 310.

The body portion 100 includes upper and lower wing portions 200 and 210 extending upward and downward like a general mask, and the body portion 100 includes two filters made of a synthetic resin material such as non-woven fabric, PE, and nylon. Fabrics are stacked, and MB (Melt Blown) filters are inserted between the stacked filter fabrics to absorb and filter germs, viruses, fine dust, etc. by static electricity.

Hook straps 300 and 310 are provided on both sides of the body part 100, respectively. The hook strings 300 and 310 are configured to have elasticity, and one end thereof is bonded at the upper side of the outer part of the body part 100, respectively. , the other side is joined at the lower side of the outer side, respectively.

That is, one end of the lanyard 300 is joined by the lanyard junction 110 at the upper left side of the main body 100, and the other end is also joined at the lower left lanyard by the lanyard junction 130. do.

Similarly, another hook string 310 is also joined by the hook string joint 140 at the upper right side of the body part 100, and the other end is also joined by the hook string joint 160 at the lower right part. .

These hanger straps 300 and 310 are fixed to the main body 100 through ultrasonic welding, thermal bonding, etc. The hanger straps 300 and 310 are also made of a synthetic resin material, and the filter fabric of the main body part 100 is also made of a synthetic resin material, so it is easy to It is possible to fix by fusion or bonding.

The body part 100 is brought into close contact with the wearer's face by adjusting the length of the hanger straps 300 and 310 so that the quarantine or dustproof effect can be enhanced. It is spaced outwardly and becomes a hard hardening part 120. This hardening part 120 applies ultrasonic waves to the main body part 100 so that the synthetic resin material constituting the main body part 100 is melted and then cooled and hardened. It may be formed, or it may be formed while being melted and cured by heat.

Alternatively, it may be formed by applying an adhesive and then curing it.

A cutout 121 is formed in the hardening portion 120 so that a partial section of the lanyard 300 can be inserted. It is formed to be cut in the form, and this cutout 121 is formed inside than the edge of the hardened part 120.

The cutout 121 may have various shapes such as 'C' shape and '<' shape as well as 'c' shape.

Therefore, the incision 121 has a structure in which the upper and lower parts and the part facing the outside of the body part 100 are incised, and hardened parts are formed on both sides of the incision 121 as a center.

At this time, a stopper 122 that can be rotated in the front and rear directions of the main body 100 is naturally formed in the part cut in the 'c' shape by the part that is not cut.

A partial section of the lanyard 300 penetrates from the outside to the inside of the main body 100 and then pierces from the inside to the outside to form a pulling part 301, both ends of which are connected by the lanyard junctions 110 and 130.

This is to prevent the stopper 122 from loosening by contacting the lanyard 300 in an oblique direction.

The structure of the hardening part 120 may be formed in the vicinity of the lanyard junction 130, and may be formed in the vicinity of both the lanyard junction 110 and the lanyard junction 130.

In addition, another lanyard 310 similarly penetrates through the hardened portion 150 having the same structure as the lanyard 120 to form a pulling portion 311, thereby preventing the lanyard 310 from loosening.

On the other hand, the upper end of the upper wing 200 provided in the main body 100 is joined at the inner surface of the upper end of the main body 100 to form an upper joint 201, and the lower wing 210 The lower end of the body 100 is bonded to the inner surface of the lower end to form the lower joint 211 .

In addition, the upper wing portion 200 is provided with a nose support 203 in the horizontal direction centering on the central portion, and the length is such that it can be closely attached while wrapping the nose of the wearer in the horizontal direction. do.

The upper joining portion 201 and the lower joining portion 211 are formed by ultrasonic fusion, so that when the wearer spreads the upper and lower wing portions 200 and 210 upward and downward, respectively, the upper joining portion 201 and the lower joining portion 201 are formed. It rotates upward and downward from the junction 211, respectively, and unfolds.

The hanging straps 300 and 310 are provided on the left and right sides of the main body 100, respectively, and both ends thereof are bonded to the main body 100 by ultrasonic welding and are formed of a material having elasticity.

In the present invention, the upper temporary joint 400 and the lower temporary joint 410 are formed in order to adjust the size of the mask by adjusting the lengths of the upper wing 200 and the lower wing 210.

The upper temporary joint 400 is joined at a distance from the upper joint 201 in the downward direction, and is formed to follow the shape of the upper joint 201, so that the body portion 100 is formed at the lower side of the upper joint 201 And the upper wing portion 200 is temporarily joined.

That is, the upper temporary joint 400 is positioned between the upper joint 201 and the nose support 203 .

The upper temporary joint 400 is formed in the horizontal direction with the central portion of the body portion 100 as the center, and its length is equal to or longer than the length of the nose support 203, and its both ends are It is formed so that it is connected to the upper junction part 201 and is not joined.

Similarly, the lower temporary joint 410 is joined at a distance from the lower joint 211 in the upward direction, and may have an interval corresponding to the interval between the upper joint 201 and the upper temporary joint 400.

In addition, it is formed to follow the shape of the lower junction part 211, so that the body part 100 and the lower wing part 210 are temporarily joined at the upper side of the lower junction part 211, and the central part of the body part 100 is centered It is formed in the horizontal direction, and it is preferable to have the same length as the upper side temporary joint 400.

Of course, the shape and length of the upper temporary joint 400 and the lower temporary joint 410 can be formed differently according to the shape of the main body 100, and the upper temporary joint 400 or the lower temporary joint ( 410) may be selectively formed, but it is preferable to form the upper temporary joint 400 or the lower temporary joint 410 together in terms of quarantine or anti-vibration effect.

The upper temporary joint 400 and the lower temporary joint 410 are bonded with pressure by a press, so that the upper temporary joint 400 and the lower temporary joint 410 from the main body 100 can be worn without damaging the mask. to be separated by the force of

In addition, in addition to temporary bonding by press, it may be formed in a line shape by thermal bonding, ultrasonic fusion, or bonding using an adhesive.

Of course, the upper temporary joint 400 and the lower temporary joint 410 may be formed using various means other than the above means for temporary joining.

A wearing state of the present invention will be described with reference to FIG. 2 .

The wearer spreads the upper wing part 200 and the lower wing part 210 up and down from the body part 100, respectively, and then wears it by hanging the hook straps 300 and 310 on the ears. When the pulling parts 301 and 311 are held with both hands and pulled after wearing the part 100, the body part 100 adheres to the wearer's face, and the lanyard 300, 310 is held by the hardening part 120. This is to prevent unwinding in the reverse direction.

The upper wing portion 200 and the lower wing portion 210 are rotated upward and downward from the upper temporary joint 400 and the lower temporary joint 410, respectively, to unfold. In this case, the upper temporary joint 400 As a result, the size of the upper wing portion 200 extending from the body portion 100 is reduced, and similarly, the size of the lower wing portion 210 extending from the body portion 100 by the lower temporary joint 410 will also be reduced. .

At this time, if the size of the mask fits the wearer's face and is sufficiently adhered, the wearer presses the nose support 203 in the shape of the nose to bring the upper wing portion 200 into close contact with the face, so that the face and the mask are in close contact.

However, if the size of the mask is small, when the wearer pulls the upper wing portion 200 and the lower wing portion 210 with force from the body portion 100, the temporarily joined upper temporary joint portion 400 and the lower temporary joint As the bonding portion 410 is separated from the main body portion 100, the size of the mask can be greatly adjusted as it is further spread upward and downward as indicated by dotted lines.

Of course, the wearer selectively separates the upper temporary joint 400 and the lower temporary joint 410, which are temporarily joined to suit their face, from the main body 100, so that the upper wing 200 or the lower wing 210 You can adjust the size.

In addition, the pulling parts 301 and 311 of the hanging straps 300 and 310 can also be pulled with both hands to shorten the length. When the given hanging straps 300 and 310 are pulled from the outside, the hanging straps 300 and 310 are released.

' 형태로 절개되고, 상기 절개부(151)의 중간부위는 상기 본체부(100)를 향하는 방향으로 'ㄷ' 형태로 돌출되도록 절개된 주절개부(152)가 형성된다.On the other hand, FIGS. 3 and 4 show another form of the cutout 151, and the cutout 151 is '

' shape, and the middle part of the cutout 151 is formed with a main incision 152 cut so as to protrude in a 'c' shape in the direction toward the main body portion 100.

In addition, the first incision 153 is formed by extending in a '⊃' shape from the upper end of the main incision 152, that is, the upper rear end, and the lower part of the first incision 153 is the main incision ( 152) extends upward from the upper rear end and has a backward rounded shape, and the first cutout 153 is formed in a downward oblique direction toward the outer direction of the main body 100 as a whole.

That is, the first cutout 153 has a rounded shape and is formed in a downward oblique direction toward the outside of the main body 100 .

In addition, the second incision 154 is formed by extending in a '⊃' shape from the lower end, that is, the lower rear end of the main incision 152, and the upper part of the second incision 154 is the main incision ( 152) extends downward from the lower rear end and has a backward rounded shape, and the second cutout 154 is formed in an upward oblique direction toward the outer direction of the main body 100 as a whole.

That is, the first cutout 153 has a rounded shape and is formed in a downward oblique direction toward the outside of the main body 100 .

The hook string 310 is inserted into the first upper cutout 153 and the second cutout 154 to be caught, so that it serves as a stopper that is not easily loosened.

That is, one end and the other end of the hanger string 310 are fixed by fusion at the upper and lower sides of the outer side of the main body 100, and the pulling part 311, which is a partial section, is of the main body 100. It is inserted through the incision 151 from the outside to the inside. The pulling part 311 has a '⊃' shape and is folded into two strands. It is inserted into the cutout 154, and the remaining strands on the upper side are also inserted into the first cutout 153 from the outside of the body portion 100.

At this time, as shown in FIG. 5, the first cutout 153 and the second cutout 154 come into contact with the rear surface of the lanyard 310, which means that the first cutout 153 and the second cutout ( 154), the protruding portions 153-1 and 154-1 come into contact with the rear portion of the lanyard 310.

In addition, the hardening part 120 and the pulling part 301 on the opposite side are formed in the same way, and are formed in opposite directions to face each other.
