Description

The present invention relates to a portion of a mask covering the wearer's mouth and nose that covers the face (hereinafter, "mask body portion").

As a three-dimensional mask that covers the wearer's mouth and nose, there are the following in the prior invention.

Patent registration 4917312 Japanese Patent Application No. 6-96934

The mask according to the patent document has a shape in which a gap is unlikely to occur between the back of the nose and the cheek.

In addition, the three-dimensional shape that does not stick to the mouth makes it easy to breathe.

However, since the mask does not have a fixture that retains the shape between the back of the nose and the cheeks, there is a possibility that a gap may be formed between the back of the nose and the cheeks according to the movement of the face. In addition, a gap may occur depending on the height of the wearer's nose and the shape of the cheeks.

In addition, regarding the three-dimensional shape that does not stick to the mouth of the mask, since there is no fixture to hold that shape, the convex shape in the vertical center of the mask is dented depending on the strength of the wind pressure and the strength of the suction force of the intake air. It leaves the possibility of sticking to the mouth.

Therefore, an object of the present invention is to have a shape that does not create a gap between the back of the nose and the cheek, which the mask or a three-dimensional mask similar to the mask has, and the portion located between the back of the nose and the cheek can be fixed. It is to provide a mask in which the convex shape at the vertical center of the above is not dented by an external pressure such as wind pressure or attractive force of intake air.

In order to solve the above problem, two pieces of C-shaped wire consisting of a right wire and a left wire are attached to the mask main body of a mask having the same or similar shape as the above-mentioned mask (hereinafter, "conventional three-dimensional mask"). , The right wire extends over a part of the upper right side of the mask body, draws a curve near the center of the upper side of the mask body, traces the joint line which is the vertical center of the mask body, and traces the joint line of the mask body. A curve is drawn near the center of the lower side and placed over a part of the lower right side, the left wire extends over a part of the upper left side of the mask body, and a curve is drawn near the center of the upper side of the mask body. Provided is a mask main body portion characterized in that a joining line which is a vertical center of the mask main body portion is traced, a curve is drawn near the center of the lower side of the mask main body portion, and the mask main body portion is arranged over a part of the lower left side.

In the mask main body of the present invention, the forming material is not limited to the non-woven fabric. A mask made of a material capable of forming the shape of the mask body of the present invention, such as cloth, paper, resin, polyethylene, or urethane, shall be according to the present invention.

Further, the wire of the mask main body of the present invention is not limited to metal. Resin, bamboo sticks, paper cores, urethane, etc. may be used, and a mask using a member having a fixing action with a similar shape that clearly shows that the shape of the wire used for the mask main body of the present invention is the basis. According to the present invention.

Further, the wire of the mask main body of the present invention may be arranged so as to extend not only a part of the upper side but also the entire upper side and a part or the whole of the side surface.

Further, the wire of the mask main body of the present invention may be arranged so as to extend not only to a part of the lower side but also to the entire lower side and a part or the whole of the side surface.

Further, the wire of the mask main body of the present invention may have a single portion corresponding to the joint line which is the vertical center of the mask. (Claim 2)

The fixing portion when the mask having the mask main body portion of the present invention is attached to the face may be integrated with the mask main body portion or a separate member, and the left and right ears as in the above patent document. It may be a shape to be hung on the head, a shape extending to the back of the head of the wearer in a band shape, and being fixed to the head by adjusting the length of the fixing portion, or any other method. The shape of the fixing member and the member may be anything.

Similar to the "conventional three-dimensional mask", the mask using the mask body according to the present invention has an excellent fit because it is difficult to create a gap between the back of the nose and the cheek, and the shape has a space between the mask and the mouth, so it is stretched on the mouth. Since it does not stick, it has the effect of eliminating the discomfort of sticking to the mouth.

In addition to the above features, unlike the traditional three-dimensional mask, a wire is placed in the lower part of the trousers type, where the essential components that are clear to the wearer are placed in the tangent line between the back of the nose and the cheeks. Therefore, the portion can be fitted according to the wearer, and the shape is maintained. Also, partial dent in external pressure due to attraction of wind pressure and suction in traditional stereo mask, but leaving the possibility that sticks to the mouth, mask using the mask body according to the present invention is the longitudinal center of the mask junction Since a wire having a function of pushing back the external pressure due to the wind pressure or the attractive force of the intake air is arranged near the line, the possibility that the portion sticks to the recess due to the external pressure due to the wind pressure or the attractive force of the intake air is eliminated.

Furthermore, since the wire passes over the ala of nose so as to trace the groove of the ala of nose, it has a better fit than a mask using a straight wire that straddles the cheek and the back of the nose in the horizontal direction, and the wire straddles the back of the nose. The foreign body sensation caused by this is eliminated. Further, the straight wire needs to be bent to fit, but the mask using the mask main body according to the present invention does not need to do so.
In addition, since a series of wires support the wing of the nose and the chin, it is unlikely to shift even if there is movement of facial expressions or vibration due to movement.

The present invention has the comfort of not sticking to the face because it does not dent under external pressure such as wind pressure or the attractive force of inspiration, and moving the mouth while the mask is stuck to the face causes the skin and the mask to rub against each other and cause rough skin. Or, in addition to eliminating the factor that lipstick adheres to the mask, the same effect can be expected even when accompanied by intense breathing such as when playing sports.

Further, since the wire of the present invention is supported by sandwiching the nose wing and the chin, it is unlikely to be displaced even if there is a movement of facial expressions or vibration due to the movement. It is less likely to adversely affect performance.
