BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] 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.
2. Description of the Related Art
[0002] 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.
[0003] 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.
[0004] However, in addition to the inherent difficulty in breathing by having the mouth
and the nose covered by a mask, since 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.
[0005] On the other hand, 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.
[0006] However, the need of the manufacturing equipment for molding integrally and the large-scale
manufacturing process pushes up the manufacturing cost. Besides, storage or transportation
of many facial masks results in generating dead space.
[0007] A mask showing the features of the preamble of claim 1 is known from US-A-5,467,765.
For contouring the face mask on the nose and the cheeks of the wearer, this document
proposes to place a metal/plastic PVC-strip along one upper edge of the top inner
perimeter.
[0008] From WO 97/46123 (folling under Article 54(3) EPC) a universal fit face mask is known.
In this mask, an elastic member is arranged between two layers of the mask and attached
to the middle layer of three layers.
[0009] Both of the above two latter-mentioned proposals do not solve the problem of the
mask collapsing during inhalation of the person wearing the mask.
SUMMARY OF THE INVENTION
[0010] In order to solve the above-mentioned problems, 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.
[0011] 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.
[0012] 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.
[0013] 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.
[0014] In order to achieve the above-mentioned objects, a mask according to claim 1 is provided
by the present invention. The subclaims relate to advantageous embodiments of the
invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT
[0016] A first embodiment of the present invention will be described with reference to the
accompanied drawings.
[0017] 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.
[0018] 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.
[0019] 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. In this embodiment, 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.
[0020] As shown in FIG. 1 a , since the both end portions (shorter ends) 12 of the folded
mask main body 10 are fixed, the folded portions 11 cannot expand thereat, but can
be expanded at the other parts except the both end portions 12.
[0021] 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. In this case, the
folded portions 11 of the mask main body 10 can be expanded in the vertical direction.
As another embodiment, 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.
[0022] As shown in FIG. 1 b , 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.
[0023] In order to maintain a straight shape, the plastic thin plate 20 is attached (fixed)
integrally to the mask main body 10 at the both ends. As to 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.
In this case, since 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.
[0024] 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. At the time, 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.
[0025] 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.
[0026] FIGS. 4 to 11 show another embodiment of the present invention. In FIG. 4, 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.
[0027] In this embodiment, the both end portions of the folded portions 11 are bound by
welding (such as welding by supersonic waves). In FIGS. 6, 10, the portions welded
by supersonic waves are marked with X.
[0028] In the case of welding, 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. In the case a material not thermally weldable
is included, 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.
[0029] 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. In this embodiment, as shown in
FIGS. 7, 8, 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.
[0030] Examples of a material of the middle member 101 include thermally weldable materials
such as polypropylene, polyester, polyethylene and nylon.In some cases, 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.
[0031] 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.
[0032] That is, 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.)
[0033] Accordingly, 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. 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.
[0034] 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.
[0035] More specifically, as shown in FIGS. 6, 10, 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. Further, 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.
[0036] Accordingly, since 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.
[0037] Although one shorter side of the rectangular rear side member 10b and one shorter
side of the rectangular front side member 10a are held by the first band-like member
30a, and the other shorter side of the rectangular rear side member 10b and the other
shorter side of the rectangular front side member are held by the second band-like
member 30b in this embodiment, 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.
[0038] In the case the air-flow resistance of the rectangular rear side member 10b is smaller
than the air-flow resistance of the rectangular middle member 101 of the mask 1 in
use, 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.
[0039] In the case 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. However, by attaching the rear side member 10b directly to the elastic
member 20 by adhesion, 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.
[0040] The numeral 50 denotes a practically deformable longitudinal member for allowing
the mask 1 to closely contact with the face, such as a wire.
[0041] Although the middle member 101 is provided between the front side member 10a and
the rear side member 10b in the above-mentioned embodiment, the mask main body 10
can consist of the front side member 10a and the rear side member 10b without the
middle member 101 as shown in FIGS. 12, 13.
[0042] Although the longitudinal elastic member 20 is stored in the rectangular mask main
body 10 in the above-mentioned embodiment, the longitudinal elastic member 20 can
be arranged on the rear side of the mask main body 10 as shown in FIG. 14.
[0043] Further, in integrating the longitudinal elastic member 20 with the mask main body
10, the longitudinal elastic member 20 can be directly welded or adhered to the front
side member 10a (or rear side member 10b). In short, any configuration can be adopted
as long as a longitudinal elastic member 20 is attached on a rectangular mask main
body 10.
[0044] Further, although both end portions of the longitudinal elastic member 20 are arranged
at both shorter sides of the mask main body in the above-mentioned embodiment (FIGS.
1 to 14) so as to be integrated with both shorter sides of the mask main body 10 by
welding, adhering or stitching, the present invention is not limited thereto. For
example, both end portions of the longitudinal elastic member 20 can be arranged not
contacting with both shorter sides of the mask main body 10 as shown in FIGS. 15 to
19.
[0045] Specifically, if both end portions of the longitudinal elastic member 20 are arranged
at both shorter sides of the mask main body 10 so as to be integrated with both shorter
sides of the mask main body 10 by welding, adhering or stitching so that both end
portions of the longitudinal elastic member 20 are at both shorter sides of the mask
main body 10 (FIGS. 1 to 14), both end portions of the longitudinal elastic member
20 stored in the mask main body 10 can be felt by the skin via the rear side member
10 so as to cause an uncomfortable feeling.
[0046] In this case, in order to cope with the uncomfortable feeling, both end portions
of the longitudinal elastic member 20 can be positioned not contacting with both shorter
sides of the mask main body 10 so that the longitudinal elastic member 20 can be integrated
with the mask main body 10 by welding, adhering or stitching the vicinity of the longitudinal
elastic member 20 so as to maintain the state as shown in FIGS. 15 to 19 ( in FIGS.
6, 10, 17, the x mark denotes a portion welded, adhered, or stitched). As a method
for integrating the longitudinal elastic member 20 with the mask main body 10, the
longitudinal elastic member 20 can be directly welded or adhered to the mask main
body 10.
[0047] Both end portions of the longitudinal elastic member 20 are arranged at substantially
the center part of both shorter sides 12 of the mask main body 10 in the above-mentioned
embodiments(FIGS. 1 to 19).
[0048] Although a plastic thin plate was presented as an example of the longitudinal elastic
member 20 in the above-mentioned configuration (FIGS. 1 to 19), it is not limited
thereto, but as a material, metals and other materials can be used. In short, a member
which can generate elastic deformation in a substantially convex shape with the substantially
center portion of the mask main body 10 projecting by the deformation of the elastic
member 20 and the mask main body 10 together at the time of expanding the darts at
the time of wearing the mask 1 on the face. Although a single longitudinal elastic
member 20 is provided in the drawings of the above-mentioned embodiment (FIGS. 1 to
19), it can be provided in a plurality as needed.
[0049] Since the both end portions of the folded portions are bound by welding, adhering
or stitching but the other parts of the folded portions are not bound, and a longitudinal
elastic member is provided with the longitudinal direction parallel to the longer
sides of the mask main body, with the both end portions of the longitudinal elastic
member arranged on the shorter sides of the mask main body and integrated with the
shorter ends of the mask main body by welding, adhering, or stitching in the mask
according to claim 1, by expanding the folded portions at the time of wearing the
mask on the face, both the elastic member and the mask main body deform to have a
substantially convex shape with the substantially center portion of the mask main
body protruding, which is maintained owing to the existence of the elastic member.
Since the rear side of the substantially convex-shaped mask main body becomes a substantially
concave shape on the user's face, the mask hardly comes in direct contact with the
mouth so that the handiness of the mask is improved. Besides, since the mask has the
configuration of expanding the folded portions of the substantially flat-shaped mask
at the time of putting on the face, the mask can be packed in a compact form in the
substantially flat shape at the time of shipping from the manufacturing plant.
[0050] Since the mask according to claim 1 comprises the longitudinal elastic member arranged
on the rear side of the mask main body, the movement of the rear side of the mask
main body toward the mouth by the user's breath can be prevented.
[0051] Since the longitudinal elastic member is stored in the rectangular mask main body
in the mask according to claim 2, in addition to the effect of the mask of claim 1,
the rectangular mask main body comprising a ventilating material, such as paper, fabric,
and non-woven fabric comes in contact with the face but the longitudinal elastic member
does not come in direct contact with the face, the handiness of the mask can be improved.
[0052] Since the longitudinal elastic member is arranged between the rectangular middle
member and the rectangular rear side member in the mask according to claims 5 or 6,
in addition to the effect of the mask of claim 1, the rectangular rear side member
comprising a ventilating material, such as paper, fabric, and non-woven fabric comes
in contact with the face but the longitudinal elastic member does not come in direct
contact with the face, the handiness of the mask can be improved.
[0053] Besides, since the air-flow resistance of the rectangular rear side member is smaller
than the air-flow resistance of the rectangular middle member, the rectangular middle
member 101 tends to move toward the mouth. However, owing to the longitudinal elastic
member, the movement is prevented. And since the air-flow resistance of the longitudinal
rear side member is smaller than the air-flow resistance of the rectangular middle
member, the rear side member does not tend to follow the breath and thus the movement
of the rear side member toward the mouth can be prevented.
[0054] Since the rectangular rear side member is integrated with the longitudinal elastic
member by welding, adhering, or stitching in the mask according to claims 3 or 6,
in addition to the effect of the mask of claim 1, the movement of the rectangular
rear side member toward the mouth following the breath can be prevented.
[0055] Since the movement of the longitudinal elastic member can be prevented at the time
the both shorter sides of the rear side member and front side member are integrated
by welding, adhering or stitching in the mask according to claims 3 or 6, in addition
to the effect of claim 1, the elastic member can be attached to the inside of the
mask main body easily.
[0056] In a mask according to the invention, by expanding the folded portions at the time
of wearing the mask on the face, both elastic member and mask main body deform together
to have a substantially convex shape with the substantially center portion of the
mask main body protruding, which is maintained owing to the existence of the elastic
member. Since the rear side of the substantially convex-shaped mask main body becomes
a substantially concave shape on the user's face, the mask hardly comes in direct
contact with the mouth so that the handiness of the mask is improved.
[0057] In a mask according to the invention both end portions of the longitudinal elastic
member stored in the mask main body are arranged not contacting with both shorter
sides of the mask main body when the mask is on the face so that they cannot be felt
by the skin via the rear side member so as to eliminate the uncomfortable feeling.
[0058] Since both end portions of the folded portions are bound by welding, adhering or
stitching but the other parts of the folded portions are not bound, and a longitudinal
elastic member is provided with the longitudinal direction parallel to the longer
sides of the mask main body, with both end portions of the longitudinal elastic member
arranged not contacting with the shorter sides of the mask main body and integrated
with the mask main body by welding, adhering, or stitching the vicinity of the longitudinal
elastic member , by expanding the folded portions at the time of wearing the mask
on the face, both elastic member and mask main body deform to have a substantially
convex shape with the substantially center portion of the mask main body protruding,
which is maintained owing to the existence of the elastic member. Since the rear side
of the substantially convex-shaped mask main body becomes a substantially concave
shape on the user's face to ensure the space between the mask and the mouth, the mask
hardly comes in direct contact with the mouth so that the handiness of the mask is
improved.
[0059] Besides, since the mask has the configuration of expanding the folded portions of
the substantially flat-shaped mask at the time of putting on the face, the mask can
be packed in a compact form in the substantially flat shape at the time of shipping
from the manufacturing plant.
[0060] Furthermore, the uncomfortable feeling can be eliminated.
