Another object is to so construct this napkin that while it may be cheaply manufactured, it will afford the protection required of such a garment.

In carrying out these objects, the invention is susceptible of modification without departing from the spirit or sacrificing any of the advantages of the claimed invention, there being shown in the drawing for illustrative purposes a preferred and practical lform in which:`

Fig. 1 represents a perspective view of the completed article embodying this invention in the shape in which it is placed on thev market. f

Fig. 2 is a similar view showing the outer covering or envelope partially open to disclose the interior construction, the absorbent layers being shown broken away to more clearlygdisclose the inner liner or iillerf Fig. 3 is a longitudinal section through the completed article. Fi 4 is a transverse section taken on4 the line 4-4 of Fig. 3; and

Similar reference characters indicate correspogiding parts in all the iigures. y

In the embodiment illustrated in Figs. 1 to 4, the body of the napkin 1 may be composed of any suitable absorbent material such as cotton layers, paper in sheet form or any other cheap absorbent material. As shown, this napkin body is composed of a plurality of layers or plies 2, any desired number of which may be employed to produce the necessary thickness, a waterproof inner liner or filler 3 being arranged near the bottom of said body between the plies thereof over which are arranged'one or more of said plies to absorb any fluid which may pass around the edges of the filler. The side edges of the absorbent layers or plies preferably extend beyond the side edges of the iiller as shown at 4 in Fig. 4 to avoid all possibility of the edges of the filler chang the skin of the user. This filler or inner liner 3 may be composed of any suitable waterproof sheet material such as rubberized cloth, sheet rubber, oil cloth, oil silk or paratiin treated fabric, the requirements necessary being that it shall be impervious to fluid.

This inner liner or ller 3 is placed between the plies or layers of absorbent fabric near the bottom ofthe article and the ends thereof extend beyond the ends of the layers and are turned inwardly as shown at 5 and covered by yother layers and secured to the body by any suitable means, glue 6 being' here shown for this purpose.

This pad 1 is designed to be encased in a cheese-cloth orany suitable envelope or cover 7 which is shown in the form of a rectangular sheet having theedges 8 thereof lapping when in operative position, the double or multiple ply ends 9 thereof being foldable one over the other as shown in Fig. l when the pads are to be packed in a suitable container and these ends are designed to be open 'out and used as attaching elements for securing the pad in operative position when in use. i

The gist of the invention resides in the arrangement of a waterproof inner liner in an absorbent pad of this character and so locating it as to prevent all possibility of iuid passing through or beyond the edges of the pad. Y

In the form shown inFig. 5, the construction is exactly the same as that shown in the other figures except that the corners of the pad are rounded as shown at 10 to render the device more comfortable and to prevent the corners 'from catching in clothing.

While the details disclosed may be considered as preferred, it is to be understood tion, variations may be made.
