R. M. SCHMITT El AL FACIAL MASK AND MEfI-IOD OF MAKING THE SAME Feb. 4, 1936.

Filed July 51, 1935 RUM m 601% m Biz/6Q @Tcu Owdmorm 475M Patented Feb. 4, 1936 STATES EPATENT GFFI C'E FACIAL 'MASK AND THE METHOD OF MAKING SAME Application July 31,

9 Claims.

The invention has relation to facial masks for the use of surgeons, nurses and others, in operating rooms, hospitals and other places, having for an object to provide a satisfactory comfortable germ or spray proof mask which can be readily made in quantity at the cost of a fraction of a cent each so that it may be discarded after use, whereas the ordinary facial mask or such masks as have been developed are either not germ or spray proof or their cost is too great and they require periodical laundering and repair.

Another object is to provide a novel method of making such masks.

The invention consists in the novel construc tion and combinations of parts, and in the novel associated steps hereinafter set forth in the claims.

In the accompanying drawing illustrating the invention,

Figure l is a perspective View of the mask as applied, or in use.

Figure 2 is a face View of the mask from the inner side with the gauze raised or in first position.

Figure 3 is a similar view with the gauze folded down on the waxed paper.

Figure 4 is a section on the line 4-4, Figure 2. Figure 5 is a section on the line 5-5, Figure 3. Figure 6 is a view similar to Figure 5 but showing the gauze single rather than double as in 3. Figures 4 and 5.

In the drawing, the numeral I designates a rectangular piece of waxed paper, such for instance as parafilm paper, impervious to the expiratory spray, and of the usual dimensions, having secured thereto along the top edge of the outer side thereof a rectangular piece of gauze 2, which may be of either single or double thickness, upper and lower tapes 3 and 4 being secured along the upper and lower edges of the mask. The dimensions of the waxed paper I may vary from 8 by 5 to. 10 by '7 inches, and. of the gauze 2, from 5 by 4 to '7 by 5 inches. It is preferred to use waxed paper having considerable wet strength.

The method of making the mask is as follows:

The piece of gauze 2 is placed in position above the waxed paper I on a suitable table or other support, with the lower edge portion of the gauze lapping the upper edge portion of the waxed paer, the upper tape 3 being then laid in. position over the lapped portions of the gauze and waxed paper, the lower tape 4 being also laid in position along the lower edge portion of the waxed paper, as shown in Figures 2 and 4 of the drawing, these tapes being preferably of the paper 1935, Serial No. 34,068

variety commonly used by florists in tieing up packages and of width about one fourth inch althrough one half inch width would be better. These tapes may of course be of other suitable material.

The parts being assembled as stated, heat and pressure is applied along the upper and lower tapes only by the use of suitable means, such for instance as heated rollers or heated rods, the idea being to confine the heat and pressure to the upper and lower tapes, whereby sufiicient only of the wax of the paper will be melted to pass through the pores of the gauze and cause adherence of the edge portion of the gauze to the waxed paper and to the upper tape and of the lower tape to the waxed paper, the parts being in this way securely connected together and the body of the waxed paper being unaffected by such heat so that its impervious character relative to the expiratory spray is entirely preserved.

The piece of gauze 2, is now folded over the upper edge of and down upon the inner side of the waxed paper, as shown in Figures 3, 5, and 6 of the drawing, after which the mask is ready for use.

This method of folding will avoid pressure of the tape or tapes against the face of the wearer of the mask.

We claim:-

1. A facial mask, comprising a body of waxed paper, an inner layer of gauze, and upper and lower tapes, said gauze layer and said tapes having wax connection with said paper.

2. A facial mask, comprising a body of waxed paper, an inner layer of gauze, and upper and lower tapes, said gauze layer and said tapes having wax connection with said paper derived from the wax of the paper.

3. A facial mask, comprising a body of waxed paper, an inner layer of gauze, and upper and lower tapes, said gauze layer and said tapes having wax connection with the paper along the lines only of the tapes.

4. A facial mask, comprising a body of waxed paper, an inner layer of gauze, and upper and lower tapes, said gauze layer and said tapes having wax connection with the paper along the lines only of the tapes derived from the wax of the paper.

5. A facial mask, comprising a body of waxed paper, an inner layer of gauze, and upper and lower tapes, said gauze layer and said tapes having wax connection with the paper derived from the wax thereof, an edge portion of the gauze lapping an edge portion of the paper, the upper tape overlying said lapped portions, and the gauze being folded down upon the waxed paper.

6. A facial mask, comprising a body of waxed paper, an inner layer of gauze, and upper and lower tapes upon the outer side of the paper, said gauze layer and said tapes having wax connection with the paper derived from the wax thereof, the gauze being doubled and having an edge portion thereof lapping an edge portion of the paper, said upper tape overlying said lapped portions, and the doubled guaze being folded over the upper edge of and down upon the inner side of the waxed paper.

7. A method of making facial masks, comprising assembling a body of waxed paper, an inner layer of gauze, and upper and lower tapes, and thereafter applying heat and pressure to partially melt wax of the paper and secure the gauze and the tapes to the paper.

8. A method of making facial masks, comprising assembling a body of Waxed paper, an inner layer of gauze, and upper and lower tapes, and thereafter applying heat and pressure along the lines only of the tapes to secure the gauze and the tapes to the paper.

9. A method of making facial masks, comprising assembling a body of waxed paper, an inner layer of gauze, and upper and lower tapes with the lower edge portion of the gauze lapping the upper edge portion of the paper and the upper tape overlying the lapped edge portions, and thereafter applying heat and pressure along the lines only of the tapes to partially melt the wax of the paper and secure the gauze and the tapes to the paper, and finally folding the gauze over the upper edge of and down upon the inner side of the Waxed paper.
