Description

Disposable Mask for Yellow Sand

The present invention relates to disposable yellow dust masks, broadly disposable masks for respiratory protection from dust or bacteria.

Protects the health of individuals from deterioration of the natural air environment such as yellow dust, which is often caused by climate change of the earth, air pollution due to rapid urbanization due to economic development, environmental pollution caused by population growth, and dust or germs generated from artificial working environment Often it is necessary to wear a mask in order to do so.

Square cloth masks are widely used in the prior art has the advantage of being able to continue to use while washing at low cost, but there is little dust and dust antibacterial effect on the fine dust other than the warming effect.

There are two types of face masks for respiratory protection: forming cup shape or flat folding shape. The flat folding form can be stored in the wearer's pocket before use, and can be folded flat after use to keep the inside of the mask clean within the pocket.

As a collapsible mask, 3M Korean Patent No. 10-0439481 (Korean Patent Publication No. 10-1998-0702678, International Publication WO 1996/28217) includes a first member (upper member) and a second member (lower member). The cup-shaped cup is folded flat so that at least a portion thereof is kept in contact with the common surface of the central part and covered with the nose and mouth of the wearer by the unjoined edges of the central part and the first member and the second member during use. A mask for forming an air chamber is disclosed. Since the mask has a structure where the unbound edges of the upper and lower members contact and seal the wearer's nose, cheeks and chin, it is not comfortable to wear and the outer boundary of the unbonded edge must be shorter than the periphery of the mask so that it can be folded flat. And the upper and lower members face to face contact has a disadvantage that the structure is greatly limited.

When the face mask for the respiratory protection effect is improved in both the conventional molding cup shape or the conventional flat folding mask mask, the intake of the first member (upper member) and the second member (lower member) It is common to attach a separate exhalation valve because the exhalation heated by body temperature is relatively free due to the filter cloth forming the central part, and it is difficult to discharge and the user feels cramped. This requires additional manufacturing costs.

An object of the present invention is to provide a yellow dust mask having improved barrier property and good fit.

It is another object of the present invention to provide a respiratory protective mask that can replace the exhalation valve with a simple structure and can be economically mass-produced.

According to the present invention, a middle lobe filter cloth having four corners and four sides, a wear band fixed to the four corners, and a seam or a cut line on a circular arc joined to have the same edges on the upper and left and right sides of the middle lobe filter cloth. There is provided a mask for yellowing or respiratory protection which consists of a curved upper and buccal fixed upper lobe. In the mask of the present invention, the upper lobe is folded flat on the mesenchymal filter cloth surface during storage, and the upper lobe edge and the mesenchymal filter cloth left and right sides which are spread out by contacting along the contour of the face by the nose alignment of the nose clip during use. It forms a breathing space that is blocked by the outside air around the nose by the surface near the lower side. Since there is no lower lobe, it is preferable to bend and bond the lower end of the mesenchymal filter cloth instead of the lower lobe to fit the jaw line.

If necessary, the lower lobe of the mesenchymal filter cloth may further include a lower lobe bonded to have the same edge on the lower side of the left and right sides and having a seam or a bending line on an arc. In storage, the lower lobe is folded flat on the mesenchymal filter cloth surface as in the upper lobe, and when used, it spreads downward to surround the surface along the jaw line. It is important to allow the middle width of the lower lobe in contact with the tip of the jaw to be larger than the periphery so that the upper lobe does not pull down even if the jaw moves during conversation. A breathing space that is blocked by outside air around the nose by the upper and lower edges of the upper lobe edge and the mesenchymal filter cloth left and right sides, which are contacted along the facial contour by the face contact surface of the lower lobe along the jaw line and the contour of the nose of the nose clip. Form.

Preferably, the left and right sides of the mesenchymal filter cloth has a lining film on a protruding arc, and the inlet film is in close contact with the side of the face when inhaled while the mask is worn, and is exhausted from the side of the face when it is exhausted to facilitate the exhaust. Preferably, the four corners are on the protruding arc and the side protruding length of the draft film on the protruding arc is shorter than the protruding arc length of the corner.

The upper lobe, the mesenchymal filter cloth or the lower lobe are made of the same nonwoven fabric as the case may be, and preferably made of a composite nonwoven fabric which comprises a meltblown nonwoven fabric imparted with static electricity and constitutes an outer layer by a spunbonded nonwoven fabric. In particular, the lining is a soft material such as polypropylene mixed with polyethylene to use a soft spunbonded nonwoven fabric. When using the mask of the present invention, the upper lobe and the lower lobe are inverted so that the soft lining spunbonded nonwoven fabric comes into contact with the face. The upper lobe or the lower lobe covers the part where the wear band is fixed at the time of development for use, thereby eliminating foreign body feelings of the wear band fixing part, thereby improving the fit.

The wearing band is fixed to the upper lobe or the lower lobe and the middle lobe filter cloth and the multi-fusion spliced onto the mosaic by ultrasonic superimposed strength to strengthen the strength does not break even by high tension of the wear band.

The nose clip is preferably a soft, inelastic material made of a straight, two- or two-shaped metal yarn or metal pieces. In some cases, it may be a memory material such as a memory alloy or resin that reacts to temperature.

The wear bands may be fixed to the upper left and lower corners of the middle filter cloth and the upper and lower corners of the middle filter cloth, respectively, in the form of earrings, or the upper left and right corners of the middle filter cloth and the lower left and right corners of the middle filter cloth, respectively, to form a double head band. . These bands are made of stretchable materials such as thermoplastic elastomers and rubbers. It is preferably made of thermoplastic elastomer and ultrasonically fused to the four corners of the mesenchymal filter cloth.

The mask of the present invention can be manufactured by a separate Korean Patent Registration No. 78331, "Ultrasonic fusion apparatus for the mask" filed by the same applicant as the present invention.

The mask manufacturing apparatus of the Korean Patent Registration No. 78331 includes an upper lobe supplying part, a lower lobe supplying part, and a middle lobe filter cloth supplying part, and includes a product completion part for forming and cutting the upper lobe, the middle lobe filter cloth and the lower lobe, and the product completion part is laminated. The embossing pattern for forming and the cutting for cutting the product are made by separate ultrasonic horns to improve the feed rate of the product to increase the production rate, so that mass production is possible, and thus the mask of the present invention can be manufactured very economically.

According to the present invention, a yellow dust mask or a respirator protective mask having improved barrier property and a comfortable fit can be mass-produced by a batch production line of paper feeding and finally fusion, molding, and cutting, which can be provided very economically.

1 to 3, a mask having a three-leaf configuration consisting of the upper lobe, the middle lobe, and the lower lobe will be described. These embodiments of the invention are intended to illustrate the invention and do not limit the protection scope of the invention. The two-leaf mask of the present invention is constructed by excluding the lower lobe in the three-leaf configuration of FIGS.

Inner layer filter cloth (2) consisting of three layers of outer layer spunbonded, middle layer melt blown and inner layer spunbonded inner layer (3) The upper welding line 13, the circular seam sewing line 11, and the upper left and right corners 6 are bonded and welded together so that the upper edge is the same by ultrasonic welding. Similarly, the lower lobe filter cloth 3 which consists of three layers is bonded and fused so that the lower edge may be the same by mosaic fusion of the lower joining line 14, the circular seam sewing line 12, and the lower left and right corners 6 by mosaic. Elastic yarns 4 made of polyester are bonded to the four corners 6 of the mesenchymal filter cloth 1 by ultrasonic welding.

During storage of the mask, the upper lobe filter cloth 2 and the lower lobe filter cloth 3 are folded flat so that the middle lobe filter cloth 1 and the lining face each. In the use of the mask, the upper lobe filter cloth 2 is extended upward and buried in the upper lobe filter cloth and contacted along the contour of the face by the contour of the nose of the straight metal piece nose clip 5 fixed by the ultrasonic welding seam.

The lower lobe filter cloth (3) is folded flat on the surface of the mesenchymal filter cloth (1) like the upper lobe when the mask is stored, and when used, the lower edge of the filter cloth (3) is wrapped around the surface along the jaw line.

The upper lobe filter cloth (2) and the middle lobe filter cloth (1) face each other with lining and are joined by an upper seam line (13) and a circular seam seam (11), and the lower lobe filter cloth (3) has a middle lobe filter cloth (1) and a lower seam line (14). The circular seam seam 12 is joined. During mask storage, the upper lobe filter cloth (2) and the lower lobe filter cloth (3) are folded flat to the mesenchymal filter cloth (1), but when used, the upper lobe filter cloth (2) and the lower lobe filter cloth (3) are expanded up and down the middle lobe filter cloth (1), respectively. The mesenchymal filter cloth 1 is formed by the arc seam 11 and 12 to form a convex shape similar to the contour of the face, and is contacted along the contour of the face by the nose contour of the nose clip 5 of the upper lobe filter cloth 2. The face contact surface near the upper lobe edge unfolds, the left and right side of the mesenchymal filter cloth (1), and the lower lobe edge wrap around the jaw line by the downward direction of the lower lobe filter cloth (3). Create a breathing space that is blocked from outside air.

The left and right side membranes 8 on the protruding arc of the mesenchymal filter cloth 1 are free of circular arcs, and the inlet membrane 8 adheres to the side of the face when inhaled while the mask is worn. Departure to facilitate exhaust. The lateral protrusion length of the blowing film 8 on the protruding arc is shorter than the protruding arc length of the corner 6. In the case where the length of the side projection of the blowing film 8 on the protruding arc is the same as the length of the protruding arc of the corner 6, it is not easy to perform ultrasonic fusion cutting due to a large load at the end.

The upper lobe filter cloth 2 and the lower lobe filter cloth 3 are respectively joined by ultrasonic waves so that the lining of the middle lobe filter cloth 1 faces each other. In particular, the four corners 6 on which the wearing bands are fixed and the upper and lower ends are cut and fusion bonded to have the same edges, and in particular, the four corners 6 are mosaic-bonded to have higher strength. The upper lobe filter cloth 2 and the lower lobe filter cloth 3 cover the part where the wear band is fixed at the time of deployment for use, and the lining is in contact with the face to remove the foreign body feeling of the wear band fixing part to improve the fit. When the lower lobe filter cloth (3) is unfolded and the lower edge covers the jaw line, the upper lobe is pulled down when the jaw is moved, as if the width is formed so that the pleat (7) is caught in the middle part located at the end of the jaw. It can prevent it from moving.

The mask of the present invention supplies the upper lobe filter fabric (2) to the upper lobe supply part, the lower lobe filter fabric (3) to the lower lobe supply part and the mesenchymal filter cloth (1) by the mask manufacturing apparatus of the Korean Patent Registration No. 78331, the product completion part It can be manufactured very economically as it can be mass-produced in a consistent process by laminating by embossing pattern molding and cutting for fusion and product cutting by ultrasonic horn.
