A face-mask which is made of a plastic sheet in which is embedded a deformable skin-colored, plastic-coated wire mesh. The plastic sheet is moldable and has an octagonal shape that will fit over the face of a wearer to cover the wearer's nose and mouth with tabs to fit under the chin. A trapezoidal opening is formed in the plastic sheet at a location that will overlie the nose and mouth of the wearer. A fastener system, located at the perimeter of the opening, surrounds the opening to fasten detachably a filter element in a position that covers the opening. The filter element is in sheet form having a shape complementary to the shape of the opening. Elastic cords hold the face-mask on the head of the wearer.

FIELD OF THE INVENTION 
The present invention relates to a novel face-mask that can be molded to 
the face of a wearer. 
BACKGROUND OF THE INVENTION 
Many different types and styles of face-masks have been advanced, and each 
in its own fashion is suitable for a particular purpose. The faces of 
people vary greatly with respect facial features regarding size, 
arrangement, facial contours, etc. which makes it difficult for people to 
fit a pre-molded mask. Consequently, a need still exists for an 
inexpensive face-mask that can be used for long periods of time and will 
fit the special facial features of the individual wearer. 
SUMMARY OF THE INVENTION 
It is the principal object of the present invention to provide a face-mask 
that can be molded to the special facial features of the face of an 
individual wearer, and which will have the ability to be used with 
replaceable filters. 
Further, it is an object of the present invention to provide a novel face 
mask that can come in different sizes and can readily be molded to the 
special facial features of the face of an individual wearer, and thereby 
not ride on the face. A still further object of the present invention is 
to provide a face-mask which can be reused by easy replacement of an 
inexpensive filter element of the face-mask which can be readily cleaned, 
which will not hide the wearer's appearance, which will blend into the 
face of the wearer and which has a streamlined look. 
The foregoing objects of the present invention are achieved by the 
provision of a unique face-mask structure that enables the mask to be 
molded by a wearer to the special facial features of an individual wearer, 
and thereafter, will retain the molded shape. This is generally 
accomplished by a mask structure that consists of a metal screen or mesh 
that is embedded in a biologically safe plastic material. The structure of 
the mask includes an opening, generally overlaying the nasal region and 
the mouth. A filter element, of a color to match skin color, is detachably 
mounted to the mask structure to enclose the opening. The skin-colored 
filter element is composed of fibrous material, and the filter is 
detachably retained on the main face mask structure in a manner, such as, 
using a pull tab, so that it can be removed and replaced easily. Also, the 
face-mask structure includes a soft resilient bead, such as, foamed 
plastic, which surrounds the perimeter of the mask on the side in contact 
with the face of the wearer, so that the mask can be worn comfortably and 
can maintain a better seal with the face of the wearer. Other and further 
objects of the present invention will become readily apparent from the 
following detailed description of a preferred embodiment of the invention 
when taken in conjunction with the appended drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT 
Referring now to the drawings, and in particular to FIGS. 1 to 3 and 7, a 
preferred embodiment is now described. The novel mask 10 consists of a 
skin-colored, plastic-coated metal mesh 20 that is embedded in a plastic 
sheet or laminae 22. The mesh 20 is preferably stainless steel but may be 
aluminum or any other suitable material. Mesh 20 is comprised of about a 
1/8 inch woven mesh coated with a skin-colored suitable plastic, such as, 
polyvinyl. The mesh 20 is flexible, bendable and moldable, and will retain 
whatever shape it is bent or molded into. Accordingly, mesh 20 is capable 
of being fitted closely to the face and head of the wearer. The plastic 
sheet 22 into which the mesh 20 is embedded may be any suitable plastic 
material that is bio-compatible, transparent and can be deformed into and 
will hold a shape by the molding of the mesh. Clear polyvinyl plastic 
would be a suitable material by way of example, but not limitation. 
The plastic sheet 22 with mesh 20 embedded is preferably of substantially 
octagonal shape with from about 1.5 to about 2 inch length sides 24 to 38. 
The shape may be circular or some other regular or irregular shape that 
will overlie the face of the wearer and fit under the chin, but octagonal 
is preferred. Side 24 has a V-shaped cutout at 40 to form a pair of tabs 
42 about 3/8 inch in length at their outside edges to be bent or deformed 
to fit under the chin of the wearer. 
A central opening 44 in the shape of a trapezoid is provided at the central 
region of the sheet 22. The large or major base 46 of the central 
trapezoidal opening 44 lies adjacent the V-shaped cutout 40 and side 24, 
with the small or minor base 48 of the trapezoidal opening 44 lying remote 
from the V-shaped cutout 40 and adjacent side 32. Major base 46 is about 
11/2 to 2 inches in length, and minor base 48 is about 1/2 inch in length. 
The distance between the bases 46 and 48 is from about 11/2 to about 2 
inches in length depending on the sizing of the mask. Essentially, it is 
contemplated that three sizes, e.g. small, medium and large, should be 
sufficient, but a greater or lesser number of sizes may be made available. 
Surrounding the central opening 44 is a perimeter border 50 that is about 
1/4 inch wide. Attached to the face-mask sheet 22 around the perimeter of 
opening 44 is a 1/4 inch strip 52 composed of a material to which a filter 
element 100, as shown in FIGS. 4-6, can be securely attached, yet readily 
removed. Strip 52 may be comprised of, for example, a glassine paper to 
which certain types of adhesive can secure in a detachable way. Any 
suitable material may be used for the strip 52 that has the property of 
allowing an adhesive to secure to the strip in an easily detachable way. 
Since such materials are well know in the art to those of ordinary skill, 
no attempt will be made to elaborate further. Strip 52 can be made of a 
material to which a disposable fibrous filter element 100 can be secured 
directly, provided the filter element 100 can also be easily detached to 
allow a further replacement, disposable filter element 100 to be attached. 
Alternatively, as shown in FIG. 8, it is possible to use a mechanical 
system for mounting a disposable filter element. Such a system would use, 
for example, a strip 52 the outer portion 140 of which has a one half 142 
of a Velcro hook and loop fastener, and the inner portion 144 of which 
adjacent the opening 44 is a smooth surface. A groove 146 is defined 
between the two portions. A simple planar disposable fibrous filter 
element 100, in sheet form, is overlaid the opening 44 and the strip 52 
with its edges overlying and registering with the groove 146. A closure 
element 148, in the configuration of the strip 52, with a depending 
projection tongue or rib 150 that is received in the groove 146, overlies 
the strip 52. The complementary half 152 of the velcro hook and loop 
fastener is secured to the closure element 148 on it downwardly facing 
side to cooperate with the part of the Velcro fastener on the strip 52, 
and the depending rib 150 fits into the groove 146 trapping the disposable 
fibrous filter element 100 therebetween, to hold the filter element 100 in 
a detachable position. Upon removal of the closure element 148, including 
removal of the rib 150 from the groove 146, the filter element 100 can 
easily be taken off and replaced. In this system, no adhesive is required. 
The filter element 100 is shown in FIGS. 4-6 and consists of a sheet of 
fibrous material 102 in the shape of the opening 44 and strip 52, that is, 
trapezoidal, and is cut to register with the outer perimeter of the strip 
52, without interfering with the Velcro fastener, if that is the mounting 
system being used. Coated on the perimeter of sheet 102 to a width of 
about 1/4 inch to match the strip 52, is an annular or peripheral coating 
104 of a suitable adhesive that enables attachment to the strip 52, but in 
an easily detachable way. The types of adhesive that are suitable for this 
purpose are well known to those skilled in the art, and no further 
elaboration is required. The point is that the strip 52 and the coating 
104 are selected to enable the filter element 100 to be appropriately 
secured to the mask, but in an easily detachable way so that when the 
filter element is used-up or exhausted and needs replacement, it can be 
readily replaced simply and easily. Overlying the coating 104 is a 
protective strip 106 which is of a material that lightly secures to the 
coating 104, but at the same time can be very easily removed from the 
coating 104 when the filter element is to be mounted and secured to the 
mask as described. Again, such materials are well known to those skilled 
in the art and no further elaboration is required. 
As shown in FIG. 4, a tab 108 projects from the sheet 102 from one comer of 
the small base in order to facilitate removal and replacement of the 
filter element. Tab 108 does not contain the coating 102 nor the 
protective strip 106. Similarly, a tab 110 projects from the protective 
strip 106 to facilitate its removal in preparation for mounting a filter 
element 100 onto the mask. 
As shown in FIG. 7, a soft bead 112 of a resilient material, such as, 
foamed polyurethane or silicone, surrounds the mask about its perimeter, 
in order to form a tight seal or to enhance a tighter seal with the face 
of the wearer. Bead 112 can be bonded directly to plastic sheet 22 or 
bonded indirectly by means of an adhesive 114, as desired. As shown in 
FIG. 1, through-holes 116, 118, 120 and 122 are formed in the mask at four 
locations about 1/4 inch from the edge or perimeter of the mask. One hole 
116 is located at the junction of sides 28 and 30, hole 118 is located at 
the junction of sides 26 and 28, hole 120 is located at the junction of 
sides 36 and 38, and the fourth hole 122 is located at the junction of 
sides 34 and 36. These locations correspond generally to the eye level of 
the wearer's face and the mouth level of the wearer's face. Grommets or 
other reinforcement are fitted into the holes 116-122. 
Elastic cords (not shown), approximately 1/8 inch diameter, preferably 
colored a skin tone, are detachably secured in the holes 116 to 122, with 
one cord secured in holes 116 and 122 and the other cord secured in holes 
118 and 120. In this manner the mask can be mounted to the head of a 
wearer with the cords passing behind the head and generating sufficient 
tension due to stretching to hold the mask in place without riding up or 
down on the wearer's face. 
The mask is used in the following manner. First, a filter element 100 is 
inserted into or on the plastic sheet 22 around the opening 44 using 
either the adhesive technique described above or the mechanical technique 
described above. Next, the mask is fitted to the face of the wearer by 
deforming the portion of the mask that goes over the bridge of the nose of 
the wearer by appropriately bending this portion while applying the mask 
directly to the face of the wearer. The surrounding perimeter edge of the 
mask is deformed to fit the face of the wearer by molding the mask 
directly on the face to fit over the cheek areas closely. The tabs at the 
bottom are bent under the chin of the wearer to hold the mask snugly at 
this point. In this activity, the resilient bead 112 is compressed 
slightly to insure a close fit against the face and chin of the wearer. 
The elastic straps or cords are then passed around the wearer's head to 
hold the molded mask in a snug fit. In this fashion, the mask provides a 
tailor-made fit to the wearer's face and head with the filter element 
appropriately positioned over the nose and mouth of the wearer. When the 
filter element is exhausted, the mask is removed from the head of the 
wearer, and the filter element is changed, as described in the foregoing, 
and the mask repositioned on the wearer's head. If the mask becomes dirty 
or needs cleaning, it is removed, the filter element removed, the mask 
washed and the filter element replaced as previously described. 
Although the invention has been described in terms of a preferred 
embodiment, nevertheless, changes and modifications can be made which do 
not depart from the spirit, scope and teachings of the invention. Such 
changes and modifications are deemed to fall within the purview of the 
present invention as claimed.
