Patented Aug. 3, 1954 DIAPER PAD Harriette L. OBrien, Santa Monica, Calif., assignor to Marjorie 0. Koops, Los Angeles, Calif.

Application May 14, 1952, Serial No. 287,730 '5 Claims. (01. 128--287) My invention relates to improvements in diaper pads, and more particularly to an improved waterproof diaper pad.

An object of my invention is to provide an improved diaper pad having a sheet of water-proof material provided with a margin so arranged thereon that seepage of liquid past the margin of the diaper is prevented when the diaper is in use.

Another object of my invention is to provide a diaper pad of hour-glas configuration with a l plurality of fastening means for adjusting the size of the diaper pad when in use so as to prevent such seepage irrespective of the size of the baby upon which the diaper pad is used.

The foregoing and other objects of my invention will become apparent from the following specification taken in connection with the accompanying drawing wherein:

Figure 1 is a front perspective view of a. baby I with my improved diaper pad fitted thereon;

Fig. 2 is an inside plan view of my improved diaper pad;

Fig. 3 is a side elevational view of the diaper p Fig. 4 is a fragmentary cross-sectional view vention and there illustrated comprises a sheet it of water-proof material having a diaper [2 consisting of a plurality of layers of absorbent material secured thereto. The water-proof sheet l and the diaper I? are both of hour-glass configuration, the former, however, having larger dimensions than the latter. Both the water-proof sheet [9 and the diaper [2 thus form inwardly bowed marginal portions it and I6 of water proof sheet material along the two sides thereof and straight marginal portions l8 and 20 of water-proof sheet material along the back and front ends thereof. All the marginal portions are normally flat so that they can press against a babys skin to prevent seepage of moisture past the edges of the diaper pad.

The sides of the water-proof sheet I!) and the diaper l2 are relatively long whereas the ends thereof are relatively short. However, as indicated above, the ends and the sides of the sheet of water-proof are longer respectively than the sides and ends of the layers of the diaper, the differences in lengths being between about four to seven inches, so that the marginal portions l 4, I 6, I8 and are between about two inches to three and one-half inches wide. The side marginal portions are narrower at the centers thereof than at the ends to provide a good comfortable fit at the back of the babys thighs while achieving maximum water-proofing along all edges of the diaper.

The layers of absorbent material are in the form of two sheets of light-weight flannel secured together by an overlook stitch 22 along the sides thereof and one end thereof, leaving the edges thereof at the back end separate, as indicated in Fig. 4;. The edges of the individual sheets of flannel at this end may also be overlooked.

The diaper l2 consisting of the body of absorbent material so formed is then secured permanently to the sheet of water-proof material by stitching 24 along a line 26 spaced inwardly from the edges of the absorbent material by a distance of about one-half inch or more. If the edges of the layers of absorbent material are not stitched together in the manner described above, the layers may, nevertheless, be held together by means of the stitching 2:3 that secures them to the sheet of water-proof material. In any event, only the inner layer of absorbent material need be stitched to the water-proof sheet at the back side of the diaper. This arrangement has the advantage that it facilitates drying of the absorbent material after laundering.

The stitching 24 is made with a small thread of about to gauge and by means of a small needle of about size 4D in order to minimize leakage of moisture through the holes formed in the water-proof sheet in the stitching operation.

The employment of two sheets of light-weight flannel is superior to the employment of a single sheet of relatively heavy flannel both with respect to water absorbency per unit weight of fiannel material and as to speed of drying. A larger number of sheets, such as four, may also be used if desired.

Two groups of male snap fastener elements 38 and :52 are amxed at the front end and two groups of complementary female snap fastener elements 34 and 35 are afiixed at the rear end. Each of the fastener elements is of conventional type consisting of two interlocked parts, one of which extends through both the water-proof sheet and the layers of absorbent material to lock securely with the other part. The three fasteners of each group are arranged along a line about one-half inch inwardly from the adjacent end of the absorbent layers and are spaced apart about one inch. The outer fastener of each group is arranged about one-half inch inwardly from the adjacent side of the diaper pad 12.

Two male fastener elements 38 and ii] are secured to the absorbent layers and to the waterproof sheet a substantial distance from both the front edge of the absorbent layer and from the side edges thereof, being about one and one half inches from each. Two complementary fastener elements 42 and A l are permanently secured to the layers of absorbing material and to the waterproof sheet a substantial distance, say about one and one-half inches, from the front end of the absorbent layers but close to the side edges of the absorbent layers.

The corners of the water-proof sheet near the rear end of the absorbent layers are turned down diagonally, and are permanently secured in place by two of the female fastener elements i i and 38 at the adjacent corners. The fastener elements 34 and 36 pass through both the inner and outer portions of the folded corners of the waterproof sheet as well as through the corners of the diaper. This arrangement facilitates removal of the diaper pad from a baby with a minimum danger of tearing.

In use, when the diaper pad is placed upon the baby, the end marginal portions l8 and 20 of the water-proof sheet overlap around the babys waist and each of the side marginal portions Hi and It of the water-proof sheet overlap about the respective legs, as illustramd in Fig. l. The fastener elements snapped together are selected according to the size of the baby in such a way that the inner surfaces of the marginal portions of water-proof sheet press against the babys skin lightly without binding. As a result, the overlapping marginal portions of waterproof sheet around the respective legs and around the waist prevent any moisture from seeping outwardly from the diaper along the surface of the babys skin.

The sheet In is composed of flexible plastic material that is chemically inert to cleaning materials such as soap, detergent, and Chlorox usually employed in home laundries.

In an alternative embodiment of my invention illustrated in Figs. 6 and 7, the layers of absorbent material are stitched together along the edges thereof and turned inside out to form a similar pair of flannel sheets, open at one end thereof. In this embodiment of the invention, two pairs of male fastener elements, such as elements 38, are employed near the front corners to facilitate size adjustment.

The diaper pad described above is very effective for its purpose since it is both comfortable to wear and safe to use and is easily laundered.

While my invention has been described with reference to only two embodiments thereof, it will be clear to those skilled in the art that various changes may be made in the form, material, details of construction and arrangement of the elements without departing from my invention.
