ApplicatonFebruary 21, 1947;lSerial-Noj729933 (Cl. 12S-284) This invention relates :todiapers ofthe pinless preformedtypaandiin;particular,1 a diaper having apouch witha perforated Wall .positioned on the inner. surface in which ian absorbent `pad imay be held..

The :purposeof .this invention :is '.to .provide :absorbingrrneans Iin a. diaper :wherein .alltfluids will= bev contained in the :absorbing 'means, .thereby eliminating .thefpossibility'of damp or .wetgclothing-and.- also eliminatingzthe possibility of chang and the like.

In the usualformof4 diaper, partioularly'of-,the absorbent typefthe wet material is .in direct contact with the surfacezof the `skin of the wearer, and after saturation the excess :moisture is absorbed `by the clothing. With this thought inmind,.-the diaper of thisinvention includes .an enclosed absorbent element 4wherein fluids will' pass through rthe -perforations in the Awall-of fa. pocket inwhich 'the absorbent element is positioned and will remain inthe .absorbent materiali so that .they will not spreadfover ytheskinof thel inf antror contact. :the fclothing.

The object of this invention is, therefore, to provide means 'forvincorporatingan absorbent pad in a pouch in a diaper wherein the absorbent pad is positioned to receive substantially all uids discharged in the diaper.

Anotherobject of this invention is fto provide a diaperhaving an absorbentpad-holding.pouch in .which the end of the pouchfis flared lto .facilitateinserting and removing the pad.

.Another object ofthe invention is to providean improved diaper `having an absorbent pad-holding perforated pouch incorporated therein which is of the pinless type.

A further object of the invention is to provide a diaper having an absorbent pad incorporated in a perforated pouch therein which is of a simple and economical construction.

With these and other objects in View, the invention embodies a diaper of substantially rectangular shape with leg openings in the sides and beveled ends, a pouch, the edges of which are secured to the material of the diaper wherein one end of the pouch is extended and flared to facilitate inserting and removing a pad, and an absorbent pad adapted to be inserted in the pouch. The material of the diaper and pouch is preferably a thin plastic or non-absorbent material, and the inner surface of the pouch is perforated to facilitate passage of moisture therein.

Other features and advantages of the invention will appear from the following description taken in connection with the drawings, wherein:

4Referring now toethe drawings, whereinalike reference` -characters indicate.Y .corresponding parts, the ydiaper .of this :invention .includes..a sheet l.of -thin waterproof plastic` or othernonV absorbentzmaterialsl{1,:afpouoh .H and an absorbent fpad t2.

In. the. design shown; ...the .diaper sis.` providedl with legopenin'gs I3-and IIL-ends 1|.5and-.l6ftand sloping surfaces I1 and I8 adjacent=thefendt5 and'elSiand ,20 adjacent the endfi.: Theedges of .the/.diaperare provided :witha continuouslhem 2v l. ethat-lmay .be -fprovided with fazreinforcing'strip. off-fabric .22 and the nner edge may `be secured to the sheet by an adhesive or stitches as may be desired, as indicated at the point 23. The edges of the material around the leg openings may be reinforced by an elastic cord 24 in a bead 25 and the folded-over edge 2S of the bead may be secured to the material of the diaper by stitching or a suitable adhesive.

The pouch Il is preferably formed as shown in Figure 6 with the edges thereof provided with anges 21 and 28 that may be secured to the material of the diaper by an adhesive or by stitching, and one end 29 is closed, while the opposite end is provided with an outwardly flared or funnel-shaped neck 30 which facilitates inserting an absorbent pad I2 or the removal of the pad therefrom.

Buttons 3| may be provided on the corners of the outer part of the diaper and buttonholes 32 may be provided in the hem of the opposite section, and although buttons and buttonholes are disclosed, it will be understood that fasteners of any type may be used.

The pad I2 may be formed of any suitable absorbent material, and the surface of the diaper registering with the pouch is provided with perforations 33. The perforations and pouch are positioned wherein substantially all fluids discharged into the diaper will pass through the perforations so that they may be absorbed by the absorbent pad.

All uids discharged into the diaper pass through the perforations to the absorbent pad in the pouch, thereby eliminating wetness from the skin of the infant, wherein the diaper will have the feel of a dry diaper, providing greater comfort to the wearer.

In order to provide a snug t around the waist of the wearer, elastic strips 34, as indicated by the dotted lines in Figures 1 and 2, are provided in the hems or waistbands l5 and I6 at the ends of the diaper. This will provide a slight tension around the waist, preventing the diaper from slipping downward.

The improved diaper of this invention, therefore, includes a diaper of usual configuration with leg openings and front and back bands, and in addition, a pouch formed in the intermediate part of the diaper with an absorbent pad in the pouch and with perforations in the diaper or wall of the pouch, wherein fluids discharged in the diaper will be absorbed by the pad and thereby removed from contact with the skin of the wearer of the diaper.

The diaper of this invention is illustrated in the preferred form, although it will be understood that modifications may be made in the design and arrangement of the parts without departing from the spirit of the invention.
