BACKGROUND OF THE INVENTION
Field of the Invention
[0001] The present invention relates to a face mask, and more particularly to a three dimensional
non-woven face mask providing protection from bacteria and dust.
Description of the Prior Art
[0002] Non-woven face masks are widely used in medical facilities, food production factories,
precision instruments manufacturing industry and other sites requiring high sanitation.
Even in public places, more and more people are wearing face mask. Nowadays, face
masks are used not only as medical products but also as daily commodities, and peoples'
requirements to the face mask is becoming more and more strict. Hence, the practical,
economic, safety, aesthetic and comfortable properties of the face mask are very important.
[0003] So far, the existing non-woven face masks are mostly two dimensional, and in order
to ensure a good filtration effect, the ends of the two dimensional face masks have
to be fastened tightly to the wearer's ears or head, so that the wearer may feel difficult
to breathe and talk, the ears may feel unconformable, and the face may feel difficult
to sweat. If such a face mask is worn by a wearer wearing glasses, the wearer's breath
will flow through the clearance between the upper portion of the face mask and the
face of the wearer to the wearer's glasses, causing foggy glasses.
[0004] The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
SUMMARY OF THE INVENTION
[0005] The primary object of the present invention is to provide a three dimensional non-woven
face which ensures a good air tightness against the face while leaving a large enough
space between the three dimensional cup and the nose and mouth area to ensure conformable
wearing, good filtration, making the wearer easy to breathe and talk. To achieve this
object, a three dimensional face mask provided by the present invention comprises:
a three dimensional cup, a three dimensional soft rubber washer, an elastic tape,
and an anti-skid band; it is characterized in that: the three dimensional cup is made
by hot pressing of multilayer of filtration material, the three dimensional soft rubber
washer is provided with a soft nose cushion and is bonded to an outer periphery of
the three dimensional cup by hot pressing, the anti-skid band is bonded to a lower
edge of the three dimensional cup, the elastic tape has two ends symmetrically bonded
to both sides of the three dimensional cup.
[0006] When the face mask is worn, a large enough space will left between the three dimensional
cup and the nose and mouth area, the soft nose cushion is fixed to a middle of an
upper side of the three dimensional soft rubber washer, and a shape of the three dimensional
soft rubber washer is similar to an outline of the face of a wearer, plus the three
dimensional soft rubber washer has a high elasticity, making the three dimensional
soft rubber washer fit snugly against the face and nose bridge of the wearer, while
snuggly wrapping around the portion of the nose above the nose tip. Furthermore, anti-skid
band is bonded to the lower edge of the three dimensional cup to naturally form a
pocket-like structure which will fit snugly against the wearer's chin with the help
of the elastic tape, so as to prevent the cap from sliding and facilitate comfortable
and stable wearing of the face mask.
[0007] As compared with the traditional face mask, the face mask of the present invention
provides a good air tightness against the face and comfortable wearing by solving
the problem of poor airtightenss caused by the uneven outline of the nose and face.
[0008] Obviously, the present invention has the advantages of simple structure, practical,
comfortable wearing, good air tightness and infiltration while allowing the wearer
to easily breathe and talk.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0010] The present invention will be clearer from the following description when viewed
together with the accompanying drawings, which show, for purpose of illustrations
only, the preferred embodiment in accordance with the present invention.
[0011] Referring to Figs. 1, 2-1 and 2-2, a three dimensional face mask in accordance with
a preferred embodiment of the present invention comprises a three dimensional cup
10, a three dimensional soft rubber washer 20, an elastic tape 30, and an anti-skid
band 40. The outer periphery of the three dimensional cup 10 which is made by hot
pressing of multilayer of filtration material, and the three dimensional soft rubber
washer 20 are bonded to the periphery of the elastic tape 30 by hot pressing. The
anti-skid band 40 is bonded to the lower edge of the three dimensional cup 10. The
elastic tape 30 is H-shaped and has two ends symmetrically bonded to both sides of
the three dimensional cup 10.
[0012] The elastic tape 30 is made of material with high elasticity, so that it can be slightly
pulled over the back of the wearer's head. The anti-skid band 40 takes the form of
a wide band and is bonded to the lower edge of the three dimensional cup 10 to naturally
form a pocket-like structure which will fit snugly against the wearer's chin when
the face mask is worn, so as to prevent the cap 10 from sliding and facilitate comfortable
and stable wearing of the face mask.
[0013] Referring then to Figs. 3-1, 3-2 and 3-3, the three dimensional cup 10 which is made
by hot pressing multilayer of non-woven filtration fabric together into a three dimensional
shape. From front view, the shape of the three dimensional cup 10 is similar to the
shape of the triangular area of the nose and mouth of the wearer, and from side view,
the shape of the three dimensional cup 10 conforms to the outline of wearer's nose
and mouth. The thickness of the filtration layer is determined by filtration function
and the number of layers of the filtration material. The periphery 11 of the three
dimensional cup 10 is made by hot pressing, the middle portion 12 of the three dimensional
cup 10 is protruded outward, so that the outer peripheral edge of the three dimensional
cup 10 is shaped in a three dimensional manner in the outline of the nose and mouth
area, leaving a large enough space between the three dimensional cup 10 and the nose
and mouth area to ensure conformable wearing, good filtration, making the wearer easy
to breathe and talk.
[0014] Referring then to Figs. 4-1, 4-2 and 4-3, the three dimensional soft rubber washer
20 in accordance with the present invention is a ring-shaped structure made by plastic
injection. From front view, the shape of the three dimensional soft rubber washer
20 is similar to the shape of the triangular area of the nose and mouth of the wearer,
and from side view, the shape of the three dimensional soft rubber washer 20 conforms
to the outline of wearer's nose and mouth. The outer peripheral edge 23 of the three
dimensional soft rubber washer 20 is bonded to the periphery 11 of the three dimensional
cup 10 by hot pressing. The structure of the outer peripheral edge 23 and a contacting
surface 22 (for contacting the wearer's face) of the three dimensional soft rubber
washer 20 conform to the peripheral structure of the nose and mouth of the wearer.
When the face mask is worn, the contacting surface 22 fits snuggly against the face
of the wearer with the help of the elastic tape 30, ensuring an ideal air tightness
against the face and a comfortable wearing.
[0015] To the middle of the upper side of the three dimensional soft rubber washer 20 is
fixed a soft nose cushion 21 which is laminated and made by plastic injection simultaneously
with the three dimensional soft rubber washer 20. When the wearer wears the face mask,
the soft nose cushion 21 will snuggly wrap around the portion of the nose above the
nose tip, ensuring a super air tightness effect, solving the problem of poor airtightenss
caused by the uneven outline of the nose and face and the problem of foggy glasses.
Especially, doctors wearing glasses won't have foggy glasses, and thus reducing medical
mistakes during operation.
[0016] Referring to Figs. 5 and 2-2, the elastic tape 30 is H-shaped and has two ends symmetrically
bonded to both sides of the three dimensional cup 10. When the face mask is worn,
the elastic tape 30 elastically wraps around the back of the wearer's head, forcing
the three dimensional soft rubber washer 20, the nose cushion 21 and the anti-skid
band 40 to closely fit against the face, the nose, and the chin of the wearer, respectively.

invention, it is clear to those skilled in the art that further embodiments may be
