Abstract

<P>PROBLEM TO BE SOLVED: To provide a mask capable of keeping a sufficient breathing space in a middle part, while both the ends are perfectly fitted to a face in use. <P>SOLUTION: Stereoscopic pleating is performed to form at least two opposing folds in a mask body. A core material for a nose is fixed to the upper side and a core material for securing breathing is horizontally fixed to the center part. Thus, when the mask is used, the sufficient space is kept in the middle part, while both the ends are perfectly fitted to the face. Then a conversation is clearly performed without disturbing breathing. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a mask, and more particularly to a non-woven flat mask having an improved structure.

Currently, there are generally two types of non-woven planar masks, ear-hook type and head-mounted type. When using the mask, for example, in order to fit the face and the mask, pleat processing is applied in the lateral direction. As a result, the surface is expanded in the vertical direction, the mask that can cover a wide range from the nose to the chin, the gap between the mask and the face is reduced, and bacteria etc. enter from the gap between the mask and the face In order to prevent this, there is a mask provided with a belt-like core material that can maintain a bent state on the upper side of the mask so as to fit the nose when used (see, for example, Patent Documents 1 and 2).

  However, when these masks are actually used, the mask body is relatively in close contact on both sides and the middle of the face, and a certain distance can be maintained between the nose, mouth and the mask body. Therefore, there is a drawback that it does not provide sufficient breathing space and hinders the clarity of breathing and conversation. Moreover, when a woman uses it, the problem that a lipstick will adhere also arises.

  Therefore, an object of the present invention is to provide a mask that is simple and rational in structure, and that can be used to maintain a sufficient breathing space in the middle while both ends of the structure fit perfectly to the face.

  In order to achieve the above object, the mask of the present invention is a mask having two hanging straps at both ends of the mask body, and at least two opposite lateral folds are formed in the mask body. A pleating process is performed, a core material for nasal muscles is provided on the upper side of the mask body, and a core material for breathing maintenance is provided in the lateral direction of the central portion of the mask body.

  The core material for maintaining breathing is preferably made of polyethylene.

  According to the present invention, when the pleat is widened in use by adopting the above-mentioned structure, the breathing maintenance core material in the central part is curved and arcuate, and is stretched so as to open the middle of the mask body. A paraboloid is formed. This keeps enough space between the nose and mouth in the center of the human face and the mask body, maintains the clarity of the conversation without obstructing breathing, and both sides of the mask body are on the face. It can be firmly attached.

  FIG. 1 is an explanatory diagram of a mask showing one embodiment of the present invention. The mask body 1 normally used in the present invention is generally composed of three layers of cloth, of which the first layer is a nonwoven fabric, the intermediate layer is a melt blown cloth, and the third layer is a nonwoven fabric. Further, an inorganic antibacterial material may be used for the non-woven fabric to exhibit an antibacterial deodorizing action. As a matter of course, the mask body 1 can also be designed to have a different number of layers or adopt materials having different functions according to the use and purpose of each user.

  The core material 2 for nasal muscles of this embodiment generally employs a metal wire or a polyethylene wire and is provided on the upper side of the mask body 1. Both sides of the core material 2 for the nasal muscles can be fixed by using a spot welding method by electric heating or ultrasonic waves, and the press-contact marks 5 are formed. The core material 2 for nasal muscles mainly exhibits a fixing action with the face, that is, it can be fixed by pressing the upper end of the mask body 1 on the nasal muscles.

  In the present invention, the mask body 1 has a three-dimensional pleat 4 formed by at least two opposing lateral folds 3. Among them, in the embodiment diagram of FIG. 1, four opposing folds 3 form two three-dimensional pleats 4, and the three-dimensional pleats 4 have two folded substantially Ω-shapes. ing.

  The respiratory maintenance core material 7 of this embodiment is provided on the pleats 4 at the central portion of the mask body 1. 1 shows a cross-sectional view, which is used to represent the respiratory maintenance core material 7. Both sides of the core material 7 for breathing maintenance can be fixed by using a spot welding method by electric heating or ultrasonic waves, and a press-contact mark 8 is formed.

  The core material for respiratory maintenance and the core material for nasal muscles may be made of metal or polyethylene, and there are no particular restrictions on the material as long as it can be bent, but considering the case where the used mask is discarded as combustible waste as it is, Polyethylene is preferred.

  The four sides of the mask main body 1 of the present embodiment can be fixed by adopting a spot welding method by electric heating or ultrasonic waves in the same manner. When the folded mask body 1 is cut, and then the two hanging straps 6 are bonded to the four corners of the mask body 1, a mask complete product is formed.

  When using the mask of this embodiment, it is only necessary to hang two straps 6 on the ears or the head and fix the pleats 4 on the mask body 1. At this time, both ends of the mask are completely on the face. Can be fitted. In the central part, since the core material 7 for breathing maintenance is bent in an arc shape, the mask body 1 stretches outward to form a paraboloid, and a sufficient breathing space is maintained between the nose, mouth and the mask body 1 to breathe. And helps maintain clarity when talking to people.

FIG. 1 is an explanatory diagram showing an example of the present invention. FIG. 2 is a reference diagram showing a use state of the present invention.
