Description
2~33~ ~
This invention r~lates to improvements in diapers.
More partiaularly, it relat~s to improvements in the design and structure of reusable, washable diapers for children who have not been toilet trained or adults who are incontinent.
Diapexs of various sorts have been in use for many years, indeed centuries. Although they have undergone many changes in recent years due to the availability of newer fabrics and modern technology, they remain and will continue to remain an unpleasant domestic problem and a substantial need for improvement.
One of the oldes~ and most common and basic types of diaper consisted o a simple piece o~ clothy usually square, folded diagonally to form a triangle which could be worn .
by an infant (or in some case-~ an adult) by pa sing two corners around the waist and one betw~en the legs and fastening them together in th~ frsnt of the abdomen, usually by means of .
a sa~ety pin.
Th~e early diaper , usualIy made of cotton, were co~veni~nt for purposes of wa hi~g but did not always serve ~heir primary purpose to contain urine and excrement.
As a result, impro~ement~ were constantly being sought to ov~rc~mq th~se problems. Some of the i~provements includ~ed sophisticated shapes to fit the body shape of the wearer, addltional padding to create areas o~ greater absorbency, adheeive means to at~ach the diaper wi~hout th~ danger and nconvenience o~ safety plns, etc. etc.

More recently, improvements have evolved to the point of producing a disposable d:iaper with elastic to form contours, adhesive strips to allow fastening, highly absorbent materials of synthetic fibres to contain moisture and the attractive advantage of disposing of the used diaper instead of washing it.
The disadvantage of these modern trends has been the production of huge volumes of disposable, and often non-degradeable, diapers which are consuming a large portion of garbage disposal sites which are becoming increasingly unavailable.
It is, therefore, the purpose of this invention to provide a diaper which fits the wearer and serves well it~ primary function to contain the moisture and messiness associated with diapers.
It is also the purpose of this invention to provide a diaper wh~ch is made substantially of natural fibres9 provides the comfort o~ cotton~ and i5 washable and reusable.
It is also the purpose of this invention to provide a diaper which is easy to use and easy to wash and reuse.
These objects and advantages are sought to be achieved by the present invention which comprises a washab.le reusable diaper comprising an oblong body o~ a plurality ~of Layers of fabric having an upper front edge and an upper rear edge and sides extending between, having a concave curvature ~and elastic emhedded along said sides to compress same, thereby to provide a f it around the legs of the wear~r. Preferably, one layer of the;body portion is a film or fabric of substantially moisture impervious material to prevent the escape of moisture through the diaper. Additional absorbency is provided by a flap of layers of absorbent fabric of length and width slightly less than the body of said diaper and attached to said diaper by stitching near the rear edge of the flap and the body.
2 0 3 5 ~ 4 rj Fastening means is provided by hook and loop fasteners having a strip of loop material on the front outer face of the diaper and tabs near the rear corners, one portion of which overlies the fabric and has a surface of loops, the other portion of which extends beyond the fabric of the diaper and has a surface of hooks.
The invention may be better understood by the following description of one embodiment thereof with reference to the drawings in which:
Figure 1 is a plan view of a diaper constructed in accordance with the present invention laid out flat;
Figure 2 is a cross-section of the body of the diaper;
Figure 3 is a cross-sectional view of the inner flap of the diaper;
: Figure 4 illustrates the diaper in the configuration when worn;
Figure 5 is an enlarged view o~ the fastening means;
: Figure 6 illustrates one alternative configuration of the diaper in Figure 1.
An embodiment of a diaper which incorporates the present invention is illustrated in Figure 1 in which the main body portion of the diaper 2 i~ a substantially rectangular oblong, plece of cloth, multi-layered, and comprising upper front edge 4 and an uppex rear edge 6.
: Along the sides 8 and 10 which extend from one ~ ~ uppe~r edge to the other on each side, the cloth is cut in ;: : a concave curvature, preferably with the edges of the abric : turned inwards to avoid fraying~
~ - 3 -:
~ ~3 ~F~
Embedded within the layers of the main body portion 2, along the edges 8 and 10, elastic is stitched to one or more layers of the fabric as illustrated by the dotted lines 12 and 14 so as to longitudinally compress the curved edges 8 and 10.
In the illustrated embodiment, the rear upper edges 4 and 6 are shown with stitching along the edges where the fabric has been turned in to form waist bands 22 and 23.
As shown in Figure 2, the main body portion which is multi-layered comprises an outex layer of cotton ~lannel 16 which presents a soft, natural fabric exterior to the garment.
N~xt to the cotton layer 16 is a layer of polyvinylchloride film 18 which provides t moisture proof barrier to prevent leakage through the body of the diaper.
~ On the other side of the PVC layer 18 are three layers of cotton flannel 20 to provide softness and absorbency ~on the inside of the diaper.
These inner Iayers 20 may be stitched together by some pattern to maintain some form and shape to the garment.
As illustrated in Figure 17 an additional oblong ~lap 24 r extends from near the front upper edge to the rear waist band, and is slightly narrower than the body of the garment in the center. It i8 attached to the main body by stitching along the line 25 at one end of the ~lap adjacent the rear waist band 23 of the diaper.
~: ~
' 2 ~3 ~
As illustrated in Figure 3, this flap consists of four layers of cotton flannel, stitched at their edges in some conventional way. The layers of the flap 24 may be stitched to each other by means of a pattern of stitching ~o help maintain the shape of the flap.
Figure 4 illustrates the embodiment of Figure 1 in its functional configuration when it is being worn with the sides 8 and 10 fitting around the leg and the waist band 22 and 23 fitting around the waist. The rear corners of the diaper are fastened by means of attachment strips 40 which are shown fastened on the viewer's right (and unfastened on the viewer's left) to a mating strip on the outer face of the front waist band of the diaper.
The fastening means 40 is better illustrated in Figure 5 in which the front upper edge 4 is downwardly displaced in order to illustrate exposed the upper inside rear portion adjacent to tha upper rear edge 6.
~ The attaching~means in the illustrated embodiment are~composed of hook and loop fasteners of the type commonly ~known by the trade mark Velcro. The outer, front face 22 has a strip of "female" fastener material 42, along the middle as illustrated.
At each rear corner, just below the upper rear ~edge 6 are two hori20ntally disposed strips 44 overlying ; ~the rear waist b,and and haviny an inner portion 46 with an ~; exposed surface of female hook and loop ~astener material ~while the outer portion 4~ of the strip has an exposed surface ~oE male fastener material.
:
~ or purposes of fastening of the diaper to the wearer, as illustrated in Figure 4, the male strip 48 of the tab 44 is wrapped around the front of the diaper and attached to the female strip 42.
For purpos~s of washing the diaper, the male portion 48 of the strip 44 can be folded against the adjacent female portion 46 (as shown at 50 to the viewer's left in Figure 5). This will avoid the tendency of the male portion to cling to other diapers or othex garments during washing or drying.
Thus, the present' invention provides a diaper, as demonstrated by the illustrated embodiment, which provides numerous advantages. First of all, the diaper is prefabricated in a shape which provides~a narrcw portion between the legs o the~wearer and a wider portion to surround the waist.
The sides of the diaper are;contoured and elasticized to fit snugly around the le~s.
..
The outside o~ the:garmen~ pres~nts a soft, comfortable surface such as would be provided by cotton flannel while the adjacent inner layer provides a waterproof barrier against leakage. The inner sur~ac0~ of the main body of the diaper provide additlonal layers o~ cot~on which ara soft again~t the skln and provide adequate absorbency. In addition, the ~flap:~4 provides addi~ional layers of mat2rial such as cotton flannel:whlch are bo~h soft and absorbent.

Because the flap 24 is stitched only at the rear end portion the two opposite ends may be extended in opposite directions as shown in Figure 1 (which is a better configuration for boys) or folded double towards the back (which is a better configuration for girls) as illustrated in Figure 6. Furthermore, because one end is unattached, the inner flap 24 is loose enough to be adequately exposed to soap and water during the washing process thus to facilitate cleaning and reusing of the diaper.
The attachment means 40 provides an adjustable, releasable, reusable fastening means which is soft and pliable and has none of the difficulty or danger of safety pins.
Furthermore, because the front portion 42 of the fastener is a female strip and because the male strip 48 has an opposite end 46 (preferably of the same size) composed of a female strip, the tab 44 may be folded together as illustrated at 50 in Figure 5 to avoid catching other garments during washing and drying~
Therefore, the present invention provides a diaper which is functional, effective and has all the features of a disposable diaper but is washable and reusable.
~ While the embodiment described above contemplates use of layers of 100~ cotton flannel and a moisture barrier of polyvinylchloride, the diaper could be made with cotton twill or with a material o~ a blend o natuxal and synthetic fibres such as 65% cotton and 35% polyester or various combinations of such materials in different layers. Similarly, the flap may be made of these alternative materials and may include a layer of absorbent non-woven fibres or wadding. The moisture barrier may be water resistant, woven nylon or other materials so long as it is water resistant and suitable for washers and dryers.
It will, of course, be realized that various features of the illustrated embodiment might be modified or varied without departing from the inventive concept herein.
