SANITARY FACE MASK CROSS-REFERENCE TO RELATED APPLICATION This application is a continuation-in-part of my prior copending application Ser. No. 210,962, filed Dec. 22, 1971 and now U.S. Pat. No. 3,740,768, and incorporates by reference the disclosure of that application.
BACKGROUND OF THE INVENTION This invention relates to a device used to protect the face of an individual and to aid in preventing the inhalation of toxic air during spraying, such as when spraying ingredients from an aerosol container during the application of hair spray, or in spraying room deodor ants, insecticides, paint, and the like. In particular, the application pertains to a device which is provided with a disposable sanitary portion closest to the face of the individual.
In the prior art, face shields and masks are known for use during the application of hair sprays. See, for example, the device shown in U.S. Pat. No. D2lO,l83. In general, it is known to provide a mask which has the outlines or contours of a face and which will fit against the forehead, under the chin and around the perimeter of the face, and which can be held in place by a handle or strap, as desired. See, for example, U.S. Pat. Nos. 825,288, 1,524,863, 3,015,105, 3,060,445, 3,103,667, 3,152,588, 3,317,921 and 3,488,772. This art shows various means for permitting an individual to breathe while using a mask. Further, it is known to use a transparent material to cover the face during the application of hair spray. A problem with these prior art devices is that they are basically unsanitary.
SUMMARY OF THE INVENTION I have overcome the deficiencies of the prior art by providing a frame in a generally hollow semi-ovoid shape, and a transparent filter material which covers the frame along that portion of the frame which is in closest proximity to the face of the person utilizing the device during spraying.
In various embodiments both the frame and the filter material structure are modified to provide additional desirable end results. In one embodiment, I have provided a handle extending from the frame to form a manual support means and, in another embodiment, I have provided a strap on the frame so that the frame can be held against the face of the user.
Separate retaining means are also provided so that the filter material can be detachably retained to the frame. In one embodiment, the separate retaining means comprises a spring clip conforming to the inner surface of the frame to clamp the filter material along that surface. In another embodiment, the retaining means comprises a complementally configured frame which, for the sake of convenience in use, is pivotally attached to a manual support means extending from said frame and which coacts with the frame to retain the filter material during use.
Several embodiments of the filter are also shown in the present application. In one embodiment, the filter has a separate packet of charcoal impregnated material situated proximate to a plurality of breather holes.
Accordingly, it is an object of this invention to provide a new and novel face mask of a filtering and sanitary type which overcomes the aforementioned deficiencies of the prior art. This and other objects of my invention will become apparent from the following description with reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE PREFERRED EMBODIMENT Although specific forms of the invention have been selected for illustration in the drawings, and the following description is drawn in specific terms for the purpose of describing these forms of the invention, this description is not intended to limit the scope of the invention which is defined in the appended claims.
Referring to the figures, various embodiments of my invention are shown, particularly in FIGS. 1 through 6, wherein it will be noted that the invention comprises a frame means forming a hollow substantially semi-ovoid with a perimeter suitably contoured for a portion of the human face, and a separate flexible sheet material forming a transparent filter means positioned about the frame, preferably so that it overlaps the perimeter of the frame, in order to provide a sanitary disposable surface adjacent to the face of the person utilizing the device. FIGS. 1 through 4 show the basic frame 10 which consists of a lightweight plastic material suitably formed into the shape of a hollow semi-ovoid with an outwardly extending flange 12 forming a perimeter. The exact contour of the perimeter or margin 12 is not critical for the present invention; it being known in the art to provide a facial contour as can be readily ascertained from the above referenced patents.
Depending from the frame is a handle 14. Pivotally mounted to the bottom thereof by means of the pin 18 is the handle 20 of a retaining means 22. The handle portion 20 is complementally configured to the handle portion 14 and overlies it in the closed condition shown in FIGS. 1, 2 and 4. The retaining means 22 is a body complementally configured to the frame 10, so that they will fit together as shown.
A specially designed sheet of material 24 is utilized for the present invention. In this embodiment it consists of a plastic bag. It is preferable to have it transparent and it is most desirable to have it made of a material which is, in part, semipermeable or foraminous, so that the material will pass air for breathing. Any suitable filter material available in sheet form which is sufficiently flexible can be used. Such filter material provides a means for filtering out the liquid particulate material and toxic gas being sprayed into the air about the head of the user, while still allowing the user to breathe normally.
The material 24 can be a composite of plastic and paper or other similar materials. The porous portion can be made ofa lightweight paper in which a charcoal dust, or other particles having a similar function, have been implanted, so as to add to the purification of the air being breathed by the user. Further, the top half of the material may be a nonporous material, since only the bottom portion closest to the handle will be used in breathing. Thus, as in the example illustrated, the top is clear plastic and the bottom has a porous charcoal impregnated filter 26.
Any suitable means can be used to join the composite sheets of material. In FIGS. 1 and 3 a separate sheet 28 of flexible plastic is attached to the material 24 to form an envelope for retaining the charcoal filter material 26. Any suitable means or methods can be used to attach the two pieces of plastic together as, for instance, by heat fusing or by adhesive. Both the separate sheet 28 and the sheet 24 are perforated by a plurality of holes clearly shown in the drawings, as for example, at 30, 32 and 34, so that air can be freely drawn through the mask and, in particular, through the filter material 26.
In the preferred embodiment the material 24 is of such a size that the outer edge of the material extends outwardly beyond the perimeter of the mask in its assembled condition, so that the mating mask and retaining means 22 help the material 24 retain its shape during use. Further, it insures a sanitary surface against the face of the user. It will be noted in this regard that the device when fully assembled as in FIGS. 1, 2 and 3 provides the user with a mask entirely composed of sanitary, disposable material in that portion which is closest to the users face. That is, no permanent portion of the device is in contact with the users face.
It will be seen from what has been disclosed that the invention provides a sanitary and air purifying face mask for use during spraying.
In operation, a user, having been provided with a dispenser of prepared flexible filter sheets, need only insert a sheet over the mask frame 10, close the handle portion 20 over the handle portion 14, and then spray while holding the protected margins of the mask against the face. Once spraying has been completed, the mask can be removed, the handles opened and the sheet material quickly disposed of.
To make the use of this device even more comfortable, I have provided a resilient material 38 along the margin 12. This resilient material can be foam rubber in a thin strip attached by adhesive to the plastic flange 12. It acts to cushion the force of the mask against the face of the user, and as a seal. FIGS. 5 and 6 show additional modifications to the basic invention. Herein, the frame 100 is identical to the frame 10 in FIGS. 1 and 2. However, instead of providing a manual support means in the form of a handle 14 as shown in FIG. 2, the manual support means 1 14 shown in phantom lines in FIG. 5 can be dispensed with. In order to hold the mask to the face of the user, a strap 115 is provided suitably attached at both ends by means of a rivet as, for example, shown at 117 in FIG. 5, to the outwardly extending margin 112 of the frame 100.
In either event, it will be noted that in the embodiment shown in FIGS. 5 and 6, the retaining means 22 is not utilized. Instead, the transparent filter bag 124 is modified in its construction and a separate retaining means is used to hold the bag to the frame 100. In particular, the bag has its inner surface cut out in a semiovoid hole (a portion of the periphery of which is designated as 125, FIG. 6) so that as the bag is positioned over the frame 100, the hole lines up with the hole in the frame. Sufficient material remains in the the bag so that it extends inwardly along the inner surface of the frame and is retained therein by means of the spring steel clip 127, FIG. 6, as clearly illustrated. Other than that modification, the bag is identical to the bag 24 previously described.
It will be understood that various changes in the details of construction could be made within the scope of this invention and, in particular, it should be clear that the handle 114 could be provided on the frame 100 if desired, instead of the strap 115.
A perspective view of the bag shown in FIGS. 5 and 6 is shown from the rear in FIG. 9. It will be understood from what has been said that such a bag could be used with various mask frames and/or with various retaining means, all within the scope of the present invention.
A perspective view of the bag shown in FIGS. 1, 2 and 3 is shown in FIG. 7, taken from the front. A greatly enlarged section, which has been foreshortened for the sake of clarity, is shown in FIG. 8. It will be ap preciated that this bag also can be used with various types of frames and/or retaining means for the same purposes and to achieve the same results as those disclosed and claimed herein.
It will be understood that various changes in the details, materials and arrange of parts which have been described and illustrated in order to explain the nature of this invention, may be made by those skilled in the art within the principle and scope of the invention as expressed in the appended claims.
It will further be understood that the Abstract of the Disclosure set forth above is intended to provide a non-legal technical statement of the contents of the disclosure in compliance with the Rules of Practice of the U.S. Patent Office, and is not intended to limit the scope of the invention described and claimed herein.
