Description

  The present invention relates to a pleat mask used for hygiene in medical, food hygiene, general industrial fields, hay fever countermeasures and daily life, and more particularly, to a pleated mask excellent in adhesion that can follow the movement of the wearer's jaw and mouth.

Usually, the mask is bonded to the face cloth that contacts the face inside the filter medium such as gauze or non-woven fabric, but recently, the particles to be collected in the medical, food hygiene, general industrial field and daily life field. Pleated masks with pleats on the filter medium have been widely used so as to prevent the leakage of air and prevent the exhalation of one's own breath from directly outside the filter medium into the outside air. However, when a face cloth is joined to a filter with pleats, there are pleats, so the nose, mouth and chin area of the human face are covered and the laces are worn over both sides of the nose and mouth. Clearances are likely to open in particularly undulating places such as on both sides, and thus the protective performance is deteriorated. In addition, since there is a gap on both sides of the nose, exhalation comes out from the gap, and there is a problem that the glasses become cloudy.
Therefore, the present inventors previously proposed a pleated mask having good adhesion by inserting a shape retainer while the peripheral edge of the filter and the peripheral edge of the face cloth are joined (Patent Document 1). ). However, a pleated mask that can follow the movement of the chin and ensure hermeticity with the face even after speaking loudly while wearing this mask has been required.

  Therefore, the present invention provides a pleated mask in which a pleat is provided on a filter medium, and the pleat mask that can ensure airtightness with the face by following the movement of the wearer's chin and mouth.

  The present invention comprises a filter having a pleat, a face cloth, and a shape holder having a three-dimensional shape along the shape of the face, and the peripheral edge of the filter and the face cloth are joined together. A pleat mask, wherein the shape retainer is inserted between the joined peripheral portions, and the airtightness between the pleat mask and the face is secured by following the movement of the chin and mouth. It is a pleated mask. In the present invention, it is preferable to use a shape retainer that can follow the movement of the jaw or mouth by making the left and right frames of the shape retainer into an arch shape.

  In the present invention, a shape retainer that can follow the movement of the chin and mouth is used as the shape retainer, so that the close contact with the face can always be ensured even when the wearer speaks loudly.

The present invention will be described in detail.
The material of the filter used in the present invention is not different from that of a normal mask such as a nonwoven fabric or gauze, and the present invention is provided with pleats.
The fabric used for the face cloth may be any stretchable nylon fiber, polyester fiber, polypropylene fiber or the like. By laminating a soft resin such as polyurethane or polyester to this fabric, it is preferable because it is elastic and has a good touch and does not allow particles such as dust and bacteria to pass through. And this face cloth cuts up and down portions such as both sides of the nose and both sides of the mouth so that the wearer's mouth and nose do not hit.
The peripheral part of the filter having pleats and the peripheral part of the face cloth are joined to form a pleated mask. Any means such as sewing, bonding with an adhesive, or welding may be used as a joining means between the filter and the face cloth, but welding is preferred from the viewpoint of airtightness.

In the pleated mask according to the present invention, a shape retainer is inserted in the space formed when the crease is opened, so that the tension between the face and the cloth of the contact cloth can be maintained, and the close contact In addition, the use of a shape retainer that can follow the movement of the wearer's jaw and mouth as a shape retainer improves the adhesion between the face and the face cloth. is there.
As a shape retainer having a shape capable of following the movement of the jaw and mouth, for example, the left and right frames of the shape retainer are made into an arch shape or a stretch spring shape, or the center frame is lacking in the center, or elastic ( It is possible to use any method such as using a material having a resilience, for example, a soft plastic resin, but the arch frame is made of polyethylene, polypropylene or polyacetal having an elasticity of about 3 to 7 mm in cross section. It is preferable to do.
And in the present invention, by inserting a shape retainer having a shape that can follow the movement of the jaw and mouth at the time of wearing, the face cloth does not contact the filtration part of the pleat mask, so the area of the filtration part is not wasted The mask performance can be used effectively. In addition, a space is created at the mouth, so that the lips do not touch the filtration part directly, and it can follow the movement of the mouth and chin even when talking with a loud voice when wearing a mask, ensuring airtightness with the face it can. In addition, the left and right frames of the shape retainer are arched in the space created when the pleat mask fold is opened, so that the face cloth can be attached to the face by inserting the shape retainer along the contour of the face. It is possible to give tension to the fabric, and it is possible to further increase the adhesion.

The pleat mask concerning this invention is shown with a figure as an Example. FIG. 1 is a perspective view of the appearance of a pleated mask according to the present invention, and FIG. 2 is a rear view thereof. FIG. 3 is a side view of the appearance of the shape retainer with the left and right frames being arched, and FIGS. 4 and 5 are explanatory views showing the movement of the shape retainer following the movement of the mouth. 4 shows a state where the mouth is closed, and FIG. 5 shows a state where the mouth is opened. In FIG. 1, the filter 1 is provided with a pleat 3, and a face cloth 2 is provided on the side in contact with the face of the wearer as shown in FIG. The face cloth 2 has cut-out portions such as both sides of the wearer's nose and both sides of the mouth. The outer periphery of the mask is welded to the peripheral edges of the filter 1 and the face cloth 2 to form a welded portion 4, and a shape retainer 6 is inserted in the welded portion 4. A crimping string 5 is provided.
FIG. 3 is a side view of the shape retainer 6. The shape retainer 5 is composed of an arbitrary number of frames along the three-dimensional shape of the face, but the left and right side frames 7 are arched, and the center frame 8 lacks the center. The lower frame 9 preferably touches the wearer's chin. These frames are made of an elastic synthetic resin or the like.
