Description

  This invention relates to a three-dimensional mask in which a spectacle lens is prevented from being fogged by closing a gap formed between the upper edge of the mask and the faces on both sides of the nose muscles when the mask is worn.

  2. Description of the Related Art Conventionally, a mask made of gauze or a non-woven flat sheet has been used for the purpose of preventing dust, pollen and the like from entering the body. However, since the face has protruding parts such as mouth and nose, there is a problem that a gap is formed between the flat sheet and the face, and intrusion of dust, pollen and the like cannot be sufficiently prevented. In addition, it has been pointed out that a person who uses spectacles is inconvenience in use that high-expired breath leaks from a gap formed on both sides of the nose muscles, and the spectacle lens is clouded.

  For this reason, a planar mask has been proposed in which a plurality of pleats are provided so as to spread in a three-dimensional shape, and a shape holding member is provided on the upper edge to match the shape of the nose muscles. Still cannot follow the three-dimensional shape of the face and still has the problem of exhalation leaking from the gap.

  In addition, apart from this, a pair of flat sheets joined to each other in a curved shape at one end edge, and a mask in which appropriate ear hooks are formed on the other side edge of these sheets, A mask called a three-dimensional mask in which a portion covering the nose is formed in a cup shape has also been proposed. Since the mask having such a structure is simple in structure and easy to mass-produce, it is provided as a single use disposable mask in consideration of hygiene.

  In these three-dimensional masks as well, there remains a problem that a gap is generated between the mask and the face and the spectacle lens is clouded by the exhaled breath, but in order to deal with this problem, Patent Document 1 3 to 3 have also been proposed in which a device is devised to improve the sealing performance by eliminating the gap between the mask and the face at least at the upper edge of the mask.

Registered Utility Model No. 3135320 JP 2007-185301 A JP 2008-279101A

  The three-dimensional mask disclosed in Patent Document 1 is provided with a shape-retaining member that can be bent and deformed along the upper edge of the mask, and correspondingly provided with a low-rebound pad material in a band shape, which is mainly harmful. The purpose is to prevent the entry of particles and the like. According to this mask, the upper edge of the mask can be bent in accordance with the unevenness of the face to be brought into close contact with the face, and further, the gap can be closed with the pad material. However, since the structure is complicated, such as the shape holding member is mounted on the upper edge of the mask and the pad is provided correspondingly, the increase in manufacturing cost is inevitable and it is not always suitable for disposable use. is there. In addition, since a uniform low-rebound pad material is provided over the entire upper edge of the mask in a strip shape, when it is closely attached to both sides of the nasal muscles, the repulsive force differs depending on the site, causing discomfort and discomfort. The problem remains that it is difficult to completely close the gap. Further, depending on the material of the pad material, the problem that high-expired breath leaks out due to the air permeability and fogs the spectacle lens has not been solved.

  Moreover, the mask disclosed by patent document 2 improves sealing property from a nose to a cheekbone by providing a pair of extension part in the upper edge of the said general three-dimensional mask. According to the mask having such a configuration, the problem that exhalation leaks from between the nose and the cheekbone can be solved to some extent, but since the distal end of the extending portion is a free end, the sealing performance may be increased depending on the movement of the face. Is not always maintained sufficiently, and the problem remains that exhalation leaks.

  The mask disclosed in Patent Document 3 is provided with a pair of protruding pieces on both sides of the center of the upper edge of the mask body, and is generated on both sides of the nose by pressing the protruding pieces against the face with a nose pad of glasses. It is intended to close the gap. Furthermore, a configuration is also disclosed in which a pressing portion is provided on the outside of the protruding piece so as to come into contact with the frame of the spectacle lens and press it against the face. However, recent spectacles place importance on design, and there are various sizes and shapes, so there is a problem that the position of the nose pad and the lens frame of the spectacles is different and the protruding piece cannot always be pressed. . Therefore, the original purpose of completely preventing the leakage of exhalation has not been solved reliably.

  The present invention has been devised to solve various problems associated with such conventional masks. In a disposable three-dimensional mask, the gap generated on both sides of the nasal muscles is reliably closed to completely prevent the leakage of the breath. The present invention provides a mask that prevents the spectacle lens from fogging.

  In order to solve each of the above problems, a mask according to the present invention includes a mask body that can be formed into a cup shape that joins one end edge of a pair of planar sheets at a curved joint portion and bulges forward. Each of the sheets is provided with an ear hook portion provided at the other end edge of each sheet, and each of the upper end edges of each sheet is provided with an angled projecting piece projecting upward, and A means was adopted in which pads were provided symmetrically on the inner surface of the protruding piece to prevent leakage of exhaled breath.

  And each sheet | seat of the mask main body was comprised by laminating | stacking a some nonwoven fabric, and employ | adopted the means that it has the airtightness, and has the blocking | blocking property of a harmful substance.

  In addition, the pad is made of an elastic material.

  The pad is provided on the inner surface of each protruding piece with a gap in the joint, and the upper edge of the pad is provided so as to coincide with the upper edge of the protruding piece of the mask body.

  Furthermore, when the spectacles were worn, the pad employ | adopted the means of being located between the lower edge part of the lens of spectacles, and a face, and becoming a buffering material.

  The mask of the present invention according to the above configuration is a three-dimensional mask that can be formed in a cup shape that bulges forward, and is provided with a protruding piece at the upper edge of each sheet, and a pad attached to each inner side surface Therefore, when it is attached to the face, the mask body covers the mouth and nose securely, and the protruding piece and the pad block the gap formed between the sides of the nose and the face. Prevent exhalation from leaking. Therefore, it is an excellent device that can be expected to have a special effect that it is possible to reliably prevent the spectacle lens from being clouded by expiration.

  In addition, the mask body is composed of multiple layers of corrosion, and the pad is composed of an elastic material, so that the breathing is ensured and the suction of elegant substances is reliably suppressed, and the flexibility of the face shape And the pad closes the gap.

  Moreover, since the shape of the upper end edge of a protrusion piece and the upper end edge of a pad is made to correspond, a clearance gap can be closed reliably according to the curve of a pad, and it looks good.

  Moreover, when interfering with the lower edge part of spectacles, a pad acts as a shock absorbing material.

1 is a perspective view of an embodiment of a mask according to the present invention. It is explanatory drawing which shows a part of state which opened the mask and was seen from the inner side.

  Hereinafter, preferred embodiments of a mask according to the present invention will be described with reference to the accompanying drawings. In FIGS. 1 and 2, reference numeral 1 denotes a mask body, in which one end edges of a pair of left and right flat sheets 1a and 1b are joined by a curved joining portion 1c. Reference numerals 2 and 2 denote ear hooks attached to the respective other edges of the sheets 1a and 1b. Such a configuration is common to this type of conventional three-dimensional mask, and the mask body 1 is expanded in a symmetrical manner with the joint 1c as a center so that the mask body 1 bulges forward to form a cup shape. It is almost in close contact from the cheek to the chin and can cover the mouth and nose. At this time, since the mask main body 1 has a cup shape, the mask main body 1 does not directly adhere to the mouth and nose, and breathing is easy and there is no uncomfortable feeling.

  Each sheet 1a, 1b of the mask body 1 is formed by laminating a plurality of layers of non-woven fabrics, for example, and has appropriate air permeability, while blocking suction of harmful substances such as dust and pollen. And the joining part 1c is joined in the curved shape which protruded outside, for example by heat welding. The ear hooks 2 and 2 are preferably made of a stretchable material, are provided in an annular shape, and are attached to the sheets 1a and 1b by heat welding. In addition, the aspect of the ear hook 2 is not limited to this, for example, the other end edge of the sheet 1a may be folded into a cylindrical shape and provided through a string member, or the other end edge of the sheet may be extended as it is. It is also possible to form an integral annular portion as an ear hook portion (see, for example, Patent Documents 1 and 2). That is, since the aspect of the ear hook 2 is not an essential part of the present invention, various known configurations can be arbitrarily adopted as the configuration.

  Next, reference numerals 3 and 3 denote chevron-shaped projecting pieces projecting upward at the upper end edges of the sheets 1a and 1b of the mask body 1 and provided symmetrically on the left and right of the joint 1c. That is, the upper end edges of the projecting pieces 3 and 3 are positioned so as to protrude upward from the upper end edge of the joint 1c. When the mask main body 1 is opened, the projecting pieces 3 and 3 are curved inwardly (face side) and are closely attached to the face along the gaps formed on both sides of the nose muscles, thereby improving the sealing performance of the part. Therefore, the protruding pieces 3 and 3 can prevent the exhalation of the breath and prevent the spectacle lens from being fogged.

  In addition, on the inner side surfaces of the protruding pieces 3 and 3, pads 4 and 4 having a predetermined thickness made of an elastic material are provided symmetrically with an appropriate gap 3a in the joint portion 1c of the mask body. The pads 4 and 4 are attached to the back surfaces of the protruding pieces 3 and 3 by any means such as an adhesive or heat welding. Further, the shape of the pad is not particularly limited, but it is preferable that at least the upper edge thereof matches the curved shape of the upper edge of the protruding pieces 3 and 3. Due to the presence of the pads 4 and 4 in this mode, the mask body 1 opens with its elasticity, and when opened to the left and right, the portion is curved inward, the gap 3a portion of the joint portion 1c is in close contact with the nasal muscles, and the pad 4 While elastically deforming 4, the gap generated on both sides of the nasal muscles is more reliably closed and tightly adhered to the face to seal the part, thereby completely blocking exhalation. Thereby, it can prevent reliably that the lens of spectacles fogs. For this reason, the material of the pads 4 and 4 is not particularly limited, but it is preferable to employ a material having air permeability so that high-humidity breath does not easily pass.

  The protruding pieces 3 and 3 and the pads 4 and 4 may interfere with the edge of the spectacle lens depending on the shape of the spectacles when wearing spectacles. The portion presses the protruding pieces 3 and 3 from above, the degree of adhesion of the protruding pieces 3 and 3 to the face is improved, and the gap is surely closed, and at that time, the pads 4 and 4 act as cushioning materials. .

  The specific manufacturing method of the mask having the above-described configuration is not particularly limited, but it can be easily achieved by sandwiching a pad with an elastic material at an appropriate position of a plurality of laminated nonwoven fabrics and pressing and cutting with a Thomson blade or the like from above. It is possible to form a mask body, and at this time, the shape of the upper edge of the protruding piece 3 and the shape of the upper edge of the pad 4 can be completely matched. Thereafter, the ear hooking portion may be formed by an appropriate means.
