Definitions

  • the present invention relates to a mask as a hygienic material used on a face, covering the mouth and the nose, in particular, to a mask used in an operation room of a hospital or in a clean room of a semiconductor manufacturing plant.
  • the facial mask In a surgical operation room or in a clean room, contamination or fouling of the indoor air by the germ or dust is prevented by the use of a facial mask. Since the facial mask needs to have substantially the same shape as the facial contour around the mouth and the nose in order to effectively shield between the inner side and the outer side of the mask, various kinds of masks are on market, including the folded type comprising a fabric partially folded with the both edges fixed, and the three-dimensionally molded type having a preliminarily three-dimensional shape without deformation.
  • the folded type comprises a single rectangular fabric partially folded with the both edges fixed so that the mask main body portion forms a substantially three-dimensional convex shape by expanding the folded part. That is, although it is an ordinary facial mask with a two-dimensional shape, it can have a three-dimensional shape by expanding the folded part in use.
  • the material of the mask comprises a fine mesh as well as the rear side of the mask main body comes in direct contact with the mouth, the air-flow area tends to be narrow. As a consequence, the mask fabric slides whenever the user breathes normally or talks with the other staff members, resulting in causing further difficulty in breathing.
  • the three-dimensionally molded type can be used as it is, without deformation since the shape of the main body portion is formed three-dimensionally in the manufacturing process, and thus it is handy.
  • a mask showing the features of the preamble of claim 1 is known from US-A-5,467,765.
  • this document proposes to place a metal/plastic PVC-strip along one upper edge of the top inner perimeter.
  • an object of the present invention is to provide a mask used on a face, capable of ensuring a space between the mask main body portion and the user's face for breathing as well as handling convenience in piling up in a large quantity during the conveyance or storage without generating dead space.
  • Another object of the present invention is to provide a mask used on a face, capable of achieving the above-mentioned object even with a simple configuration.
  • Yet another object of the present invention is to provide a mask used on a face, without the risk of contacting the rear side of the mask main body with the user's mouth even during the inhalation.
  • Yet another object of the present invention is to provide a mask used on a face, capable of achieving the above-mentioned objects without requiring much labor in expanding the folded portions.
  • the facial mask has the entire configuration as shown in FIG. 1 a , comprising a mask main body 10, an elastic member, such as a plastic thin plate 20, rubber bands 30, and side tapes 40.
  • the mask main body 10 comprises a rectangular high density mesh fabric with the middle part partially folded and fixed by the side tapes 40 along the shorter sides 12 including the folded portions 11.
  • the means for the fixation is not limited to a side tape 40 but can be other means, such as an adhesive.
  • FIG. 1 b A cross-sectional view of the mask main body 10 is shown in FIG. 1 b .
  • the folded mask main body 10 has a plurality of folded portions (superimposed portions) 11 are provided. In some cases, a folded portion (superimposed portion) 11 can be provided in the singularity.
  • the main body 10 is folded successively in one direction, but a different folding manner can be optionally adopted, such as the one shown in FIG. 2.
  • the rubber bands 30, which are attached to the shorter ends 12 of the folded mask main body 10, are to be hooked on the ears for wearing the mask 1.
  • the folded portions 11 of the mask main body 10 can be expanded in the vertical direction.
  • the rubber bands 30 can be attached to the longer sides 13. In this case, the rubber bands 30 can be attached on the head with the mask main body 10 vertically expanded.
  • the mask main body 10 is provided with the plastic thin plate 20 along the folding lines.
  • the plastic thin plate 20 is a narrow flat plate interposed by the fabrics comprising the mask main body 10 and stored inside thereof.
  • the cross-section of the plastic thin plate 20 has a rectangular shape(or a substantially rectangular shape), with the longer sides contacted with the fabrics comprising the mask main body 10.
  • the plastic thin plate 20 is attached (fixed) integrally to the mask main body 10 at the both ends.
  • the position to be fixed it is possible either to attach (fix) entirely, or partially, for example, at substantially the center of the plastic thin plate 20 to the rear side of the mask main body 14.
  • the plastic thin plate 20 is attached at the center portion only with the rear side, the attached portion cannot be observed so that the appearance is not ruined.
  • the plastic thin plate 20 not in use has a straight shape and the mask main body 10 has a substantially flat shape.
  • the mask main body 10 has a substantially convex shape with the middle part of the folded portions 11 expanded as shown in FIG. 3.
  • the plastic thin plate 20 has an arch-like shape accordingly so as to prevent deformation of the substantially convex shape portion (substantially cup-like portion) 15 of the mask main body 10. Since the plastic thin plate 20 is attached on the rear side 14 of the mask main body, the substantially convex shape 15 of the rear side 14 of the mask main body can be maintained even during inhalation so as to prevent disturbance of breath caused by the mask main body suffocating the mouth and the nose.
  • the mask main body can regain the substantially flat shape from the substantially convex shape by folding the mask main body 10 along the folding lines.
  • FIGS. 4 to 11 show another embodiment of the present invention.
  • the numeral 10 denotes a rectangular mask main body comprising a ventilating material, such as paper, fabric, or non-woven fabric.
  • the rectangular mask main body 10 has a plurality of folding lines 11 parallel to the longer sides 13. In some cases, a folded portion (superimposed portion) 11 can be provided in the singularity.
  • the mask 1 has the both end portions of the folding lines 11 bound at the both shorter side portions 12 (both end portions) of the rectangular mask main body 10 by welding, adhering or stitching.
  • the both end portions of the folded portions 11 are bound by welding (such as welding by supersonic waves).
  • welding such as welding by supersonic waves.
  • FIGS. 6, 10 the portions welded by supersonic waves are marked with X.
  • the mask main body 10 comprising a ventilating material, such as paper, fabric, and non-woven fabric, including thermal welding materials such as polypropylene, polyester, polyethylene, and nylon, but a material not thermally weldable can be partially included.
  • a material not thermally weldable it can be used in the state interposed between thermally weldable materials. That is, it can be used by laminating in the order of a thermally weldable material, a not thermally weldable material, and a thermally weldable material.
  • the rectangular mask main body 10 facing at least to the nose and the mouth comprises a rectangular rear side member 10b of a ventilating material, such as paper, fabric, and non-woven fabric with a filter function, and a front side member 10a of a ventilating material, such as paper, fabric, and non-woven fabric with a filter function, arranged on the opposite side of the rear side member 10b.
  • a rectangular middle member 101 of a ventilating material such as paper, fabric, and non-woven fabric, is interposed between the front side member 10a and the rear side member 10b.
  • middle member 101 examples include thermally weldable materials such as polypropylene, polyester, polyethylene and nylon.
  • thermally weldable materials such as polypropylene, polyester, polyethylene and nylon.
  • the middle member 101 can be made from a material other than the thermally weldable materials such as polypropylene, polyester, and the like, or other thermally weldable materials.
  • a longitudinal elastic member, such as the plastic thin plate 20 is stored inside the mask main body 10, with the longitudinal direction of the longitudinal elastic member 20 arranged parallel to the longer sides 13 of the rectangular mask main body 10 and the both end portions of the longitudinal elastic member 20 connected with the mask main body 10.
  • the both end portions of the longitudinal elastic member 20 are arranged at the both shorter sides of the mask main body 10 and integrated therewith by welding, adhering or stitching. (Although only one longitudinal elastic member 20 is shown in the drawing, two or more pieces can be provided optionally.)
  • the mask 1 since the mask 1 has the both end portions of the folded portions 11 bound by welding, adhering, or stitching but the other parts of the folded portions 11 not bound, and the both end portions of the longitudinal elastic member 20 are connected to the mask main body 10 with the longitudinal direction of the elastic member 20 arranged parallel to the longer sides 13 of the mask main body 10, by expanding the folded portions 11 at the time of wearing the mask 1 on the face, both the elastic member 20 and the mask main body 10 deform to have a substantially convex shape (substantially cup-like shape) with the substantially center portion of the mask main body 10 protruding as shown in FIGS. 9, 11, which is maintained owing to the existence of the elastic member 20.
  • the mask 1 Since the rear side of the substantially convex-shaped mask main body 10 becomes a substantially concave shape on the user's face, the mask 1 hardly comes in direct contact with the mouth so that the handiness of the mask is improved. Besides, since the mask 1 has the configuration of expanding the folded portions 11 as shown in FIGS. 9, 10, and 11, of the substantially flat-shaped mask 1 as shown in FIGS. 4, 5, at the time of putting on the face, the mask 1 can be packed in a compact form in the substantially flat shape at the time of shipping from the manufacturing plant.
  • the connection of the both end portions of the longitudinal elastic member 20 and the mask main body 10 will be described.
  • the both end portions 20a, 20b of the elastic member are arranged at the both shorter ends of the rectangular rear side member 10b and the rectangular front side member 10a, respectively. And the movement of the both end portions 20a, 20b of the elastic member 20 are prevented by heat welding of the both shorter sides of the rear side member 10b and the front side member 10a.
  • a first longitudinal curved band-like member 30a comprising a heat weldable material such as polypropylene, polyester, polyethylene and nylon holds one shorter side of the rectangular rear side member 10b and one shorter side of the rectangular front side member 10a.
  • the first band-like member 30a, one shorter side of the rectangular rear side member 10b, and one shorter side of the rectangular front side member 10a are heat welded so as to prevent the movement of one end of the elastic member 20.
  • a second longitudinal curved band-like member 30b comprising a heat weldable material such as polypropylene, polyester, polyethylene and nylon holds the other shorter side of the rectangular rear side member 10b and the other shorter side of the rectangular front side member 10a.
  • the second band-like member 30b, the other shorter side of the rectangular rear side member 10b, and the other shorter side of the rectangular front side member 10a are heat welded so as to prevent the movement of the other end of the elastic member 20.
  • the first band-like member 30a, the second band-like member 30b, and the mask main body 10 are integrated by heat welding one end of the mask main body 10 with the first band-like member 30a, the rear side member 10b, and the front side member 10a so as to prevent the movement of one end of the elastic member 20 and heat welding the other end of the mask main body 10 with the second band-like member 30b, the rear side member 10b, and the front side member 10a so as to prevent the movement of the other end of the elastic member 20, the first band-like member 30a, the second band-like member 30b and the elastic member 20 can be attached to the mask main body 10 more easily.
  • the movement of the both end portions 20a, 20b of the elastic member can be prevented by heat welding the both shorter sides of the rear side member 10b and the front side member 10a without using the first band-like member 30a and the second band-like member 30b.
  • the rectangular middle member 101 tends to move toward the mouth. However, owing to the longitudinal elastic member 20, the movement is prevented. And since the air-flow resistance of the longitudinal rear side member 10b is smaller than the air-flow resistance of the rectangular middle member 101, the rear side member 10b does not tend to follow the breath and thus the movement of the rear side member 10b toward the mouth can be prevented.
  • the rear side member 10b comprises a material with a fine texture
  • the rear side member 10b of the mask 1 in use tends to move toward the mouth due to the user's breath.
  • the movement of the rear side member 10b is prevented by the elastic member 20 so that the rear side member 10b of the mask 1 hardly comes in direct contact with the mouth.
