Description

The present invention relates to a mask having improved adhesion and a feeling of wearing which is effective for medical use, dust prevention, hay fever, and the like.

The mask is important from the viewpoint of enhancing the adhesion of the face and preventing the suction of fine particles. The shape of the mask can be broadly divided into a pleated type and a three-dimensional type.There are two types: a pleated type that expands a bellows-folded one, and a three-dimensional type that has a design that follows the shape of the face. However, in order to use the mask effectively, it is important that the mask be in close contact with the face and that it can be used for a long time without being stuffy.
Conventionally, various types of masks have been proposed. For example, in Patent Literature 1, the cover portion before wearing the mask is vertically bent from the central portion corresponding to the nose portion, and the mask is pulled up and down when worn, so that the nose portion of the mask has a three-dimensional triangular shape. This describes a mask that eliminates a gap in the nose portion of the face and enhances adhesion.
Further, Patent Literature 2 describes a mask that closes a gap between a mask and a nose portion and is used in close contact with a face.
Further, Patent Literatures 3, 4, and 5 describe masks in which a gap between a pleated mask and a face is closed to improve the adhesion.
Further, as disclosed in Patent Documents 6 and 7, the three-dimensional masks form a cover portion along the shape of the face to secure a space around the mouth and nose, and also provide a space for the nose and cheeks. Eliminating the gap enhances the tightness.

  However, in the configurations of Patent Documents 1, 2, 3, 4, and 5, when the mask is worn, a force for extending the cover in the vertical direction is applied to the left and right ends of the mask, and the cover facing the cheek is pulled forward, A large curve is formed on the cheek, and a gap is formed on the cheek. Also, since the shape of the nose varies depending on the wearer, it is difficult to match the shape of the wearer's nose, and moreover, there is a gap on both sides of the nose so that the effect as a mask can be fully exhibited. Can not.

Further, in the forms of Patent Documents 6 and 7, the cover portion is formed three-dimensionally in the front, and the mask can be effectively brought into close contact with the face of the wearer to secure the space of the mouth and nose. However, a mask having a high performance of preventing suction of fine particles closes the gap and is set to have a high sealing property, so that breathing becomes difficult when the mask is worn, and there is a problem that it cannot be used for a long time.
Furthermore, with a mask structure that can be purchased at a low cost, it is difficult to adjust the respiratory pressure inside the mask when the mask is worn. There are issues that cannot be maintained.
The present invention eliminates the gap between the mask and the sides of the wearer's nose and between the cheek and the chin, enhances adhesion and wearing feeling, and emphasizes the advantages and disadvantages of both the pleated mask and the three-dimensional mask. Therefore, it is an object of the present invention to provide a mask that exhibits the effect of the mask more.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
The masks shown in FIGS. 1 to 8 show an example of the mask 1 according to the present invention. In these figures, a mask 1 includes a cover 2 that covers at least the nose and the mouth, left and right ear hooks 7 that hold the cover 2 on the ears, and upper and lower right and left sides of the cover 2. A folding gap preventing portion 4 for filling a gap formed between the side and the side.
The covering portion 2 has a shape and a size capable of covering the nose and mouth of a wearer, and is formed by laminating one or a plurality of nonwoven sheets. The covering part 2 includes a plurality of pleats 21 to 24 extending in the vertical direction, and left and right undulating parts for raising the left and right end parts of the covering part 2 in an arch shape as the pleats 21 to 24 expand in the vertical direction. 3 is provided. Although four pleats are provided in the drawing, the invention is not limited to this. Further, in FIG. 5, a part hidden when the pleats 21 to 24 are folded is formed upward, but may be reversed. Further, folds 31 are formed in the left and right undulating portions 3 in a direction crossing the pleats 21 to 24. Further, the ear hook portion 7 has a shape that can be hooked on the ear with a string or the like formed of an elastic member.
As shown in FIG. 7 (1), each of the pleats 21 to 24 has a flat, non-spreading side seal portion 32 by being integrally joined at both left and right end portions in a folded state. Is formed.
The left and right undulating portions 3 fold this side seal portion 32 inward at a valley-folding line (a line inside the width of the fold 31 having substantially the same width as the side seal portion 32) in parallel with the side seal portion 32, and FIG. Then, when the side seal portion 32 is folded back outward again (see FIG. 7 (3)), folds 31 are formed on the left and right ends of the pleats 21 to 24 in a direction crossing the pleats. In this state, if the upper and lower ends 33, 34 of the fold 31 and the upper and lower ends of the side seal portion 32 are integrally connected, the undulating portion 3 is formed. Then, when each of the pleats 21 to 24 is spread in the vertical direction as shown in FIG. 2B, the folds 31 are extended, and the undulating portions 3 on the right and left rise. At that time, since the side seal portion 32 does not extend, the fold 31 spreads like a fan, and the undulating portion 3 rises. As a result, with at least three sides of the cover 2 in close contact with the face, the central portion of the cover 2 is separated from around the mouth.
The folding gap preventing portion 4 has a length from both sides of the wearer's nose to the side seal portion 32 and has a bag shape with an open top (see FIG. 7 (4)). One edge is joined to the upper edge of the cover 2, and the other edge of the mouth is joined to the upper edge of the sheet-like joint 35 in contact with the cheek. Furthermore, since the left and right joints 35 are joined to the left and right side seal portions 32 that are in contact with the cheek and are in close contact with the cheeks, when the pleats 21 to 24 spread in the vertical direction and the undulating portions 3 rise from the side seal portions 32, The mouth of the bag expands around the joint 35 so as to cover both sides of the wearer's nose. That is, since the upper edge of the cover 2 is separated from the joint 35 joined to the side seal 32 around the side seal 32, the upper edge of the cover 2 is joined to the sheet-like joint 35. The opened bag opens. At the same time, the tips of the bags located on both sides of the nose are pushed left and right by the small nose, so that the gap formed between the upper edge of the cover 2 and both sides of the nose is completely sealed by the bags. It is.
In the conventional mask, when each pleat is stretched in the up and down direction at the time of wearing, the left and right ends of the mask are bent in a V shape, and a gap is formed between the mask and the cheek 62. However, in the mask 1 according to the present invention, by providing the undulating portions 3 rising from the flat side seal portions 32 on both left and right sides of the covering portion 2, the surface in contact with the cheek portion 62 maintains the shape while maintaining the shape. Adhere to 62. Thereby, the degree of sealing of the mask 1 is increased.
In addition, by providing the fold 31 with a breathable sheet having excellent breathability, it is possible to increase or decrease the breathability. Thereby, even the mask 1 having high airtightness can easily breathe through the breathable sheet.
In addition, since the sheet-shaped joint portion 35 in contact with the cheek is joined to the side seal portion 32 in close contact with the cheek, by attaching both ends of the ear hook portion 7 to the upper and lower ends of the joint portion 35, The side seal portion 32 can be brought into close contact with the cheek without the force of the ear hanging portion 7 acting on the side seal portion 32. Thus, the four sides of the mask 1 can be brought into close contact with the cheek 62.
The mask 1 before being worn is in a folded state as shown in FIG. 2 (a) and FIG. 7 (5). When wearing it, the pleats 21 to 24 of the cover 2 are spread in the vertical direction. Then, each of the pleats 21 to 24 rises as shown in FIG. 2B, and at the same time, the left and right undulations 3 rise, so that the central portion of the cover 2 is separated from the periphery of the mouth. At the same time, the folding gap preventing portion 4 provided on the upper portion of the covering portion 2 spreads and closes the gap formed on both sides of the nostril, so that the peripheral edge of the mask 1 is sealed with the mouth covered. Therefore, since the air is sucked and exhausted through the air permeable sheets on both sides, it is possible to breathe in peace by selecting a gas permeable sheet having a permeability according to the surrounding environment.
The preferred embodiment of the present invention has been described above, but the present invention is not limited to this embodiment. For example, in the embodiment illustrated in FIGS. 4 and 5, the number and shape of the pleats of the cover portion 2 and the extension portions 25 are not limited to the embodiment. In addition, the folds 31 and the joining portions 35 of the undulating portions 3 on the right and left sides of the cover portion 2 may be formed with a large number of folding molds, shapes, and folds, and the number of layers of the folds 31 may be increased. .
In addition, the configuration of the undulating portions 3 on both the left and right sides of the cover portion 2 forms the folds 31 and the side seal portions 32 by folding the left and right sides of the cover portion 2 from one sheet. It may be a single sheet or a different configuration. Here, an example in which one sheet is used is shown, but the present invention is not limited to this.
Further, by using a breathable sheet material corresponding to dust, pollen, or the like for the folds 31 on the left and right sides of the cover 2, suction of fine particles can be effectively prevented. Furthermore, the air-permeable sheet material having excellent air permeability may be a multilayered sheet material, a separate structure, or an integrated structure. Further, the shape of the folding gap preventing portion 4 can be changed, and is not limited to the embodiment shown here.
Further, the configuration of the mask 1 can change the combination of the covering portion 2, the undulating portion 3, the joining portion 35, the folding gap preventing portion 4, and the ear hanging portion 7, and is limited to the embodiment shown here. Not done.
