Description
BAC~GROUND OF THE INVEMTION
Face masks that are desiyned to be worn in sanitary environments such as hospitals or the like reauire the use of a fibrous material for filtering any contaminants from the wearer. Present face masks generally utilize a sewing operation in the fabrication thereof which requires a needle to pierce the fibrous material in order to form the seams thereof. This procedure results in perforati.ons in the material such that the fibers contained therein can escape and potentially contaminate the environment. Also, the perforations provide passages for contaminates to pass through. With such masks, the fibers released by the sewing operation may be breathed by the mask wearer, as the wear is continually inhaling and exhaling through the mas~. This is an undesirable condition in that it is of primary importance that all sources of contamination be minimized to any extent possible. Therefore, there existC
a need for a sanitary face mask that does not have the disadvantages of the sewn face masks described above.
Previously developed face masks have also generally been secured to the head of a wearer by elongated ties which must be tied together bv the ~eare-.
Such ties are often di~ficult to attach together an~
sometimes tend to become unfastened. A need has ~hus arisen for a sanitary mask with looped earpieces wnich provide a comfortable fit while being easy ro a~ach over the ears of the wearer.

SU~RY OF THE INVENTION
The present invention disclosed herein comprises a method and apparatus Eor Eorming a sani-tary face mask that maintains the integrity of the mas~ material by preventing the fibers thereoE Erom escaping the confines of the material. The apparatus includes a layer oE fabric dimensioned to cover the nostrils and mouth of the wearer, the fabric Eabricated from a heat malleable material.
First and second ear loops are fabricated Erom an elongated layer oE heat malleable material~ Each end of the first and second ear loops are a-ttached to the layer of fabric on one side thereof with a 'neat formed seal.
The heat formed seal prevents the fibers from escaping from the fibrous layer.
In an alternate embodiment of the present invention, a reinEorcing member is disposed adjacent the upper edge of the face mask and a portion of the edge is folded over the rigid member and heat sealed around the perimeter of the semi-rigid member. The semi-rigid member provides support for the upper portion of the Eace mask about the face of the wearerO Pleats are formed in the fabric layer to allow expansion thereof.

2 t~a~ are Gr-e~ed hcr~ontal w_th respe~t ~o ~he face of 'h~ arer. A seam ~4 and a sea~ 25 are formed a'ong the lateral sides thereof _c ~re~en~ the ple ~s 18-~ from ~e?arat:n~ a. t~e edges. The seams 2~ an~ 20 are formed ~y he~t bor.ding tec~.ni~ues, ~h~t is, a~plyin~ ~eal a~d rressure tc fo~ a ~eal there~etween. In so doln~, only 7 ~ 3~
the center portion oE the pleats 18 2~ in the layer 1~ are allowed to expand to conform to the face of the wearer.
Given our invention, persons skilled in the art would realize that a high-Erequency method of heat bonding takes much less time than a convention heat bonding process, and therefore such persons would appreciate the advantages in terms of expense and increased production rates attendant on a high-fre~uency heat bonding process.
A semi-rigid member 28 is disposed adjacent the upper horizontal edge oE the layer 12. A por-tion of the layer 12 on the edge thereof is folded over the semi-rigid member 28 and attached to the surface thereof with A heat bonded seam 30. The seams 24 and 26 are Eormed after the seam 30 such that they form a lateral seaml thus enclosing the semi-rigid member 28 within the sterile conEines of the layer 12. A seam is formed on the diametrically opposite edge of the layer 12 by folding a por-tion thereof over and heat bonding a seam 32 therein. The seam 32 is primarily utilized to deEine the edge of the layer 12.
The ear loop 1~ is attached by heat bondin~ to one corner of the layer 12 at a point 34 and to an opposite corner on the same edge thereof to a point 36.
The ear loop 16 is attached on a diametrically opposite side oE the layer 12 from the ear loop 14 with one end thereoE attached to a point 38 on one corner thereof and to a point ~0 on the opposite corner.
Referring now to FIGURE 3, there is illustrated an expanded view of the attachment point 3A oE the ear loop 14. The ear loop 14 is Eabricated Erom a combination of texturized polyester and lycra spandex. In the preEerred embodiment, the material is formed Erom 90.33 percent of 7~ Denier texturized polyester and 9.67 percent of 40 Denier lycra spandex. This material is Cllt into a thin strip and, due to the properties oE the rnaterial, this strip will 'iroll over", that is, the edges thereof will curl up. In this manner, an elastically deformable strip is formed that has a semi-circular cross section to provide some comfort behind the ears of the wearer.

Due to the properties oE the ear loops 1~, heat bonding techniques such as rE heat bonding can be utili~ed.
Given our invention, oersons skilled in tne art would realize that the use of a syn-thetic fabric, such as the lycra spandex/polyester fahric oE the invention allows the use of a high-frequency heat bonding technique to attach the Eabric to another synthetic Eabric, and further would understand that heat bonding cannot be used with conventional rubber or thread-coaked rubber loops because their structural integrity would he destroyed. Further, persons skilled in the art would realize, given our invention, that ear loops made out of lycra spandex/polyester ~abric have more "give" than conventional ~ubber or thread-coated rubber ear loops, and as such are much more comfortable to the sensitive slcin behind the ear o~ the wearer. Thereore, to attach the loop 14 at the points 34 and 36, it is only necessary to apply suitable amounts of heat and pressure thereto. With such techniques, performation oE the mask material with a needle is not required. In the prererred embodiment, the seams 24 and 26 are Eormed by placing the free ends of the ear loops 1~ and 16 thereon and ~orming the pleats 1~-22 at the same time that the loops 1~ and 16 are bonded thereto.

The face mask includes a layer 12 Eormed of meltblown polyprop~lene ~abric with ear loops 1~ and 16 heat bonded thereto. The use of heat bonding techniques allows the attachment of the ear loops thereto without puncturing the surface of the material. This prevents internal Eibers of material from escaping to the surrounding environment.
Although the preferred embodiment has been described in detail, it should be understood that various changes, substitutions, and alterations can be made therein without departing Erom the spirit and scope of the invention as defined by the appended claims.
