Abstract

PROBLEM TO BE SOLVED: To provide a mask that has a simple structure and can be manufactured at a low cost, which can prevent, when a wearer of the mask uses spectacles, the spectacles from fogging by securing adhesion between a root of a nose of the wearer and a mask main body with less discomfort of wearing because of the mask main body in which a separate member is not required to be set.SOLUTION: Pleats are formed by providing the mask main body, which is formed of non-woven fabric and a filter, with ear hooking strings for holding the mask main body on a face, and folding the mask main body. In order to prevent expired air from leaking toward above the mask, an upper longitudinal direction center part of an outer side pleated part is bonded with a part around an upper longitudinal direction center part of the mask main body or an outer side of a face side pleated part to form a nose contact part that comes in contact, at a back side thereof around a connection part, with an apex of the nose of the wearer. The mask has a structure in which a bendable wire is attached to an upper part of the mask main body such that right and left nose contact expansion parts of the nose contact part are expanded to adhesion support from the apex of the nose along nose wings and cheeks. In addition, in order to prevent the expired air from leaking toward ahead of the mask, a ventilation blockage part that is coated with a resin or rubber solution is provided at an upper part of the mask main body.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a mask.

  As is well known, the mask is used as a hygiene product that covers inhalation of dust, pollen, and germs that are scattered in the air by covering the nose and mouth of the face.

  When the nose and cheek are covered with a conventional mask, a gap is generated between the upper edge of the mask main body and the nose or cheek. For this reason, when a person wearing glasses wears a mask, there is a drawback that breathing upwards through a gap between the upper edge of the mask and the nose or cheeks, and the lens of the glasses becomes cloudy.

  Conventionally, masks with a fogging prevention effect for glasses have been commercially available, but have a problem that the fogging prevention effect is not sufficient. In addition, there is a sponge protruding on the inner upper side of the mask. However, the sponge may cause a sense of incongruity that the face is pressed or an unpleasant sensation due to the unique smell of the material.

  The object of the present invention has been made in view of the above points, and the gap is greatly reduced by improving the adhesion without providing another member or adhesive layer between the mask body and the nose or cheek. And it is providing the mask which prevented the lens of spectacles from becoming cloudy for the person who uses spectacles.

  In order to achieve the above object of the present invention, a mask main body and a pair of ear straps provided on both sides of the mask main body are provided, and the mask main body is bent laterally so that the fold line is positioned upward. A mountain fold pleat is formed, and further folded back to form a valley fold pleat. The upper side central portion of the mountain fold pleat is lifted, fixed to the mask body, and abuts on the user's nose tip on the back side in the vicinity. A nose contact part is formed, a bendable nose wire is attached to the upper part of the mask body, the left and right parts of the nose contact part are expanded, and the mask is constructed by closely supporting the nose tip along the nose wings and cheeks doing.

  In addition, the ear hook string has a structure in which one end is fixed above the mountain fold pleat and the other end is fixed below the outer pleat that stands up outside during extension.

  Further, the above object of the present invention is configured by applying a resin or rubber solution or film thermocompression bonding to at least a part of the vertical width of the upper part of the mask body in order to prevent leakage of exhalation into the upper part of the mask. This is achieved by having a structure provided with a ventilation block for blocking ventilation between the front and back sides.

  According to the present invention, the structure is simple and can be manufactured at low cost, and the center of the mountain fold pleat of the mask body is lifted and fixed to the mask body to form a pocket along the nose, and one end of the ear strap is fold-folded pleated. With the upper part, the pocket opens three-dimensionally when wearing the mask, ensuring that the wearer's nose and the mask body are in close contact with each other without installing another member on the mask body, and prevents fogging when using glasses. A mask that can be provided can be provided.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. Each drawing is partially enlarged or reduced in order to facilitate understanding of the configuration.

Embodiment 1

  FIG. 1 is a perspective view illustrating a state in which a wearer wears a mask according to an embodiment of the present invention as viewed obliquely from above. FIG. 2 is a plan view showing a state in which the mask body is extended and the pleat portion is erected from the front side of the mask according to the embodiment of the present invention. Note that the lip guard wires 22 and 24 are not necessarily essential and may be omitted.

  As shown in FIG. 1, the mask 10 wraps the nose, mouth, jaws, etc., and has a normal function of blocking inhalation of dust, pollen, and germs that are scattered in the air, blocking cold air, and keeping warm and cold. . The mask body 12 is formed by laminating one or more non-woven fabrics, gauze, and filter fabrics having a certain area. As the filter fabrics, special electrostatic filters in which fine fibers are charged with static electricity, activated carbon A structure with odor, antibacterial antibacterial ceramic filter, etc. is used.

  Next, the mask body pleat will be described. Here, a pleat having a fold line positioned upward and a cross section having a mountain shape is defined as a mountain fold pleat 12Y, and a pleat having a fold line positioned downward and a cross section having a valley shape is defined as a valley fold pleat 12T. As shown in FIGS. 1, 2, and 4, the mask main body 12 is folded to a predetermined vertical width, and includes one or more mountain fold pleats 12 </ b> Y and valley fold pleats 12 </ b> T.

  Further, the side central portion of the mountain fold pleat 12Y forms an adhesive portion 30 that is fixed to the vicinity of the upper central portion of the mask body, so that pockets 18A and 18B are formed on the left and right with the adhesive portion 30 as the center. The structure is in contact with the cheek of the person 100. Further, the bonding method of the bonding portion 30 is fixed by welding such as ultrasonic sealing.

  One end of the hook strap 26 that holds the mask body 12 on the face is fixed above the mountain fold pleat 12Y, and the other end is fixed below the outer pleat 12A. By fixing one end of the ear strap 26 above the mountain fold pleat 12Y, the nasal contact expanding portion 16 is pulled to the face side, but the left and right pockets 18A, 18B are independent of the nasal contact expanding portion 16. Therefore, when the mask is extended and the pleats are erected, the pockets 18A and 18B efficiently swell three-dimensionally. As shown in FIGS. 3 and 5, the nose contact expanding portions 16A and 16B that contact the wearer's nose tip are formed on the back of the pockets 18A and 18B, so that they are worn when the pockets 18A and 18B are inflated. Since it almost coincides with the angle of the person's nose, the nose contact portion 16 naturally comes into contact with the wearer's nose without any sense of incongruity. Become.

  Next, description of resin processing will be described. As shown in FIGS. 1, 2, 6, and 8, the ventilation blocking portion 40 is a non-breathable portion provided in a nostril position or a portion above the nostril when the mask is worn, The upper portion of the mask main body and the face is on the non-contact side, and has a printing portion 42 provided with a width of 1/4 to 1/3 of the vertical width and coated with a resin or rubber solution. As the resin, silicon resin, polyethylene resin, vinyl chloride resin, or the like may be used. Furthermore, the printing unit 40 may be colored or designed in order to easily recognize the presence or absence of the ventilation blocking unit 40.

  FIG. 7 is a diagram schematically showing the flow of exhalation. As shown in FIG. 7 (a), the effect of the resin processing is that the ventilation block 40 is formed in the upper part of the mask, thereby suppressing the exhalation flow forward in the upper part of the mask. Even if the mask main body 12 covers the nostril and mouth, the ventilation blocker 40 prevents the exhalation from leaking forward, so that the spectacle lens is prevented from being fogged.

  Further, as shown in FIGS. 1 and 2, by providing a nose wire 20 made of a synthetic resin material having an appropriate shape retaining property and flexibility on the upper portion of the mask body 12, it can be further adapted to the shape of the face. The leakage prevention effect can be improved.

Embodiment 2

  It is also possible to increase or decrease the number of pleats. As shown in FIG. 8, the number of pleats of the mask body 12 is increased, the valley fold pleats 12T and the mountain fold pleats 12Y are fixed at the center in the side, and a convex face side protrusion 12D is formed on the face side. Also good.

  At this time, the nose contact widening portions 16A and 16B are maintained in a three-dimensional shape by the outer pleat portion 12A spreading outward and the face side protruding portion 12D spreading outward on the mask body 12 end. In addition, it will be closely supported along the nose wings and cheeks from the tip of the nose, improving the adhesion to the nose and the feeling of wearing.

  Further, as shown in FIG. 4, in the central portion of the mask body 12, the difference between the depth direction dimension L1 of the lower portion of the mask body 12 and the depth direction dimension L2 of the upper portion of the mask body is less than 10%, thereby 12A spreads only to the outside, improving the adhesion from the nose tip to the nose wings, and reducing the difficulty of breathing due to securing the mouth space.

  Further, as shown in FIG. 5, in the plane BB ′ cross section in FIG. 2, when the mask is extended and raised, the depth direction dimension L1 of the lower part of the mask body 12 is set to the depth direction dimension L2 of the upper part of the mask body. By setting it to 40% to 50%, the adhesion to the nose and the feeling of wearing can be further improved. For example, when the depth direction dimension L1 is set to be less than 40% of the depth direction dimension L2, the nose contact portion 16 does not reach the nose of the wearer 100, the adhesion is deteriorated, and the sense of security when the mask 10 is worn decreases. . Alternatively, when the depth direction dimension L1 is larger than 50% of the depth direction dimension L2, the nose contact portion 16 becomes excessive at the base of the nose and becomes wrinkled, resulting in poor adhesion when the mask 10 is worn. .

  That is, unlike the conventional mask that could only cover the tip of the nose, by providing the nose contact portion 16, the entire nose is covered with the nose contact spread portions 16A and 16B, and the wearer 100 is selected. Therefore, the adhesion between the mask body 12 and the nose can be secured.

  In addition, compared to conventional masks, it has better adhesion, and the dust and pollen that scatters in the air, blocking the inhalation of pathogens, blocking the cool air and keeping warm and cold, and the wearer wears glasses The mask is effective in preventing fogging of the glasses in a state of wearing, and does not feel uncomfortable.

  Further, unlike the conventional anti-fogging mask, no separate member such as a sponge is installed on the mask body, so that the structure is simple and the mask can be manufactured at low cost.
