. 'This invention is directed ,to an improvement in diapers of an inexpensive disposable type, constructed in a manner to be readily conformable is directed along definite channels lengthwise of the garment and thus prevented from seeping through the edges of the narrower width 4and at the same time lmaterially increasing the absorptive capacity.

20 The description is directed to a specic embodiment, more particularly shown in the accompanying drawing, wherein: l f

Figure 1 is a perspective view of the garment.

Fig. 2 is a transverse section of the same. .25 Fig. 3 is a broken perspective view showing the various layers of the garment.

Fig. 4 is a view illustrating the application of the garment. v

The improved garment is constructed with an 30 inner layer l of fine grade gauze which has been treated preferably for softness and non-absorbency. A lm of high grade absorbent cotton 2 is applied directly against the outer surface of the gauze, the effect of which is to make the 35 gauze materially softer upon skin contact and y thus less` irritating. Beyond the lm of cotton there is applied several layers of absorbent cellulose 3, these layers forming the absorbent element. Beyond the absorbent element there is 40 arranged an outer layer of waterproof paper I. The edges of the gauze layer l are extended-over the side edges of all layers, as at 5, except the outer layer, passed beneath or inwardly of the outermost layer of the absorbent element, and

45 secured firmly to the outer layer of waterproof paper by Aadhesive or like means, indicated at 6.

Securing tapes 1 are applied to the outer side of the paper layer and extendy beyond the sidel edges of the garment to permit securing the gar- 50 ment about the body of the infant as indicated in Fig. 4. The garment is applied with the longitudinal side edges passed between the legs, the

^ respectiveY ends of the garment encircling the body, whereby the projecting' ends of the tapes 55 may be tied to secure the garment in place weith- (Cl. 12S-284) out liability of slipping and without the use of the usual safety pins-or like fastening means. The tape connection is at the waist line and directly above each hip.

As the garment is necessarily of greater length 5 than width it would result, in the absence of special provision, that the absorptive capacity without leakage would be governed by the width, for the moisture would saturate the absorptive element in all directions and thus reach the sides more quickly than the ends. To avoid this and to materially increase the absorptive capacity without increase in size, the/ respective layers of the cellulose absorptive element are provided with lines of Wax or like material, as at 8, extending more or less in parallel direction longitudinally i of the garment. These lines function as guides for the moisture and tend to d irect it longitudinally of the garment, and thus the. length of the garment rather vth its width governs the absorptive capacity wi out leakage. l

Where the absorptive element is of crepe formation', the tendency of the same is to direct the moisture toward the side edges, and -this s tendency is directly opposed by the lines through which'v the moisture does not pass, and by which the accumulated moisture is compelled to travel longitudinally of the garment.

The capacity of the garment for moisture absorption is thus materially increased without 30 leakage, and as the outer layer is waterproof. there is no tendency to leak therethrough, and thus the usual outer garment of rubber or the like is unnecessary.

The garment is one in which the various layers may be readily assembled by machinery if desired, thus further reducing the cost, a desirable item 'as the garment is to be disposed of after use. It is completely soft and non-irritating; has the maximum absorptive capacity incident to its 40 size; is generally prooi` against leakage through its edges even under maximum moisture conditions; is waterproof against outer garments worn next to it: and is so inexpensive to manufacture as'to render it advantageous to 'use in comparison 45 with other garments designed for the same purpose.

Having described the invention, what is claimed as new isz-- 1. A-body garment comprising a casing for that facing vwhich comes nextthe body constructed of soft-textured, conformable, permeable materialland having outlying portions constructed of fluid-repellent material, and a filling comprising laminated sheets. of soft porous cellulosic matel 55 rial, vwith spaced apart wax stripings extending longitudinally of the sheets for the purpose and with the result of preventing escape of uid at the sides of the garment without impairing nor--V mal ow through the filling.

2. An article as deilned in claim 1, in which the plies are so arranged that the wax stripings are in substantial registry.

3. A pad for absorbing body fluids having on lanes defined by the stripes.
