Abstract

(57) [Summary] (Correction) [Purpose] To provide a mask in which a string attachment tool is integrated, which has less discomfort during wearing, excellent fit, and easy to manufacture. [Structure] A laminate of a plurality of non-woven fabrics, woven fabrics, and other filtration sheets 2, 3 and 4 formed in a cup shape, and having an edge portion at which the sheets are fused and integrated, and A mask provided with holes or slits 8 on both sides of the section for string passing.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a molded mask.

[0002]

[Prior art]

 Conventionally, masks made by laminating various non-woven fabrics and the like have been known, but usually, the tightening string is attached via a plastic or metal string attaching tool attached to the mask, or it is attached to the mask. It is directly stapled. In these cases, the string attachment or the stapler needle directly touches the face, which causes discomfort during wearing.In particular, the one using the string attachment has poor fit and is suitable for long-term wearing. It cannot be said that In addition, a process for attaching the string attachment is required, and simplification of manufacturing is desired.

[Problems to be solved by the device]

 The present invention is to provide a mask in which a string attaching tool is integrated, which has less discomfort during wearing, excellent fitability, and is easy to manufacture.

[0004]

[Means for Solving the Problems]

 The present invention is composed of a laminated body of a plurality of non-woven fabrics, woven fabrics, and the like, which are molded into a cup shape, and has an edge portion at which the sheets are fused and integrated, and both side portions of the edge portion. The mask is characterized in that a hole or a slit is provided in the string for threading.

The mask body of the present invention is made by stacking various non-woven fabrics, woven fabrics, and other sheets having a filtering function, and molding them into a cup shape by a cold molding method or the like. Since the sheet is fused and integrated at the peripheral edge of the mask, it is preferable that at least the outer surface of the non-woven fabric contains heat-melting or heat-softening fibers as constituent fibers. The mixing ratio of the heat-fusible fiber is usually preferably 20% or more, and particularly preferably 30 to 40%.

As the sheet constituting the mask, a non-woven fabric or a woven fabric for filtering fine dust, or a non-woven fabric or a woven fabric with activated carbon adhering to adsorb and remove odors or mixed with activated carbon fibers is used. can do. In addition, a bag-shaped sheet containing activated carbon may be partially used. In order to obtain an excellent filter performance for fine dust, it is preferable to laminate at least one layer of ultrafine fibers such as a meltblown nonwoven fabric.

In the mask of the present invention, the peripheral edge of the mask body obtained by laminating and molding sheets of non-woven fabric and the like is fused by a process such as ultrasonic bonding and cut into the shape of the final product. In the fused portion, the fibers of the laminated sheets are fused to each other to be hardened to some extent and strengthened to prevent breakage, but the soft feel of the surface is not impaired. However, when most of the fibers that make up each sheet are heat-meltable resin fibers, if the conditions such as the fusing pressure are made excessive and the fusing part is completely melted into a resin and becomes a single film, The soft feel of the welded part may be impaired, and fracture may easily occur at the boundary line between the fused part and the non-fused part.

In the fusion-bonded portion on the periphery of the mask, the widths of the string attaching portions on both sides are widened to form a hole or a slit for string passing. The formation of the holes and the like can be performed simultaneously with the cutting. No special reinforcement is required for the hole, but to avoid stress concentration from the string, it is preferable that the hole has a rounded shape rather than a square shape to prevent breakage.

FIG. 1 is a perspective view of a mask of the present invention, in which 1 is a mask body composed of a laminate of a plurality of sheets 2, 3 and 4 of non-woven fabric or the like, and an edge in which the sheets are fused and integrated at the periphery. The mask body 5 has a portion 5, and the widths of both side portions 6 and 7 of the mask main body are widened to provide a hole 8 for threading. 9 is a tightening cord.

[0010]

[Operation effect]

 The mask of the present invention has a structure in which a cord passing hole is directly provided in the heat-sealing portion of the peripheral portion of the mask body made of a laminated body of non-woven fabric or the like so that the cord can be passed through. The surface of this part is soft and has a soft touch, so there is no discomfort when worn, like plastic or metal stoppers. In addition, since the threading hole can be performed simultaneously with the fusing process of the peripheral portion or continuously, the manufacturing process can be simplified.
