BACKGROUND OF THE INVENTION
FIELD OF THE INVENTION
This invention relates to disposable diapers and more particularly to a contoured diaper having cro-tch seals and/or waist seals.
DESCRIPTION OF THE PRIOR ART
.
In the past, elasticized con-toured diapers have ~,'. 5, -~ been developed such as that disclosed in theIPatent to Buell No. 3,860,003, issued January 14, 1975, for "Contractable Side Portions for Disposable Diapers" wherein elastic strips are secured to the cro-tch portions of the diaper and spaced at least 3/4 inch ~rom the absorbent pad to form elasticized crotch seals for securement over the legs of the infant to prevent loss of fluid from the interior of the diaper alon~
the legs of the infant. The elasticized strips are placed more than 3/4 inch from the absorbent pad to provide a wide contractable side flap for improved containment.
In U.S. Patent to ~oon ~ Endres, No. 4~o50,l~62, elastic strips are provided in the crotch area of the diaper whereby a plurality of gross transverse rugosities across the width of the crotch section are formed -to improve the absorbent capacity at the crotch area. However, it has been found that these pleats may act as a channel resulting in excessive diaper leakage and the pleats in the crotch area make the infant's bottom uncomfortable when sitting especially while the diaper is not saturated.
~., Elasticized waist seals are old and well known for various garments including diapers. These waist seals have been for the purpose of maintaining the garment in place and have not been Eor the two additional purposes of the present invention so as to provide Eor a fluid ~narrier while also providing for a co-operative effect in conjunction with the crotch seals whereby the crotch seals provide an initial stress on the waist seals and the waist seals provide an initial s-tress for the crotch seals. Additionally, the elastic waist seals may be structured to serve as a means for securing the diaper as well.
SUl~I~RY OF T~IE Il\lVENTION
The present invention overcomes the disadvantages of the prior art diapers by providing a disposable diaper comprising a backing sheet, an absorbent pad on said backing sheet, a top sheet overlying said absorbent pad, said top sheet being secured to said backing sheet on at least two opposite peripheral edges thereof, opposed side elastic members, adhesive means securing said side elastic members to said backing sheet along two opposite side edges thereof to define crotch seals, and a waist elastic member secured to said back-ing sheet along an end edge to define a waist seal, said crotch seals and said t~aist seal cooperating to place initial stress and stretch on said waist seal and crotch seals respectively, said side members and said waist member being waterproof forming fluid seals, said absorbent pad being of an hour-glass shape defining ears spaced from said crotch area, said adhesive means extending substantially the full length of said backing sheet for preventing pulling apart of said diaper and shifting and balling of said absorbent pad.
The diaper may include two waist seals at opposite ends of the diaper.
35~
The elastic crotch and waist seals may serve as fluid barriers particularly when they overlie the absorbent pad.
The walst seal or seals may also be extended beyond the side edges of the diaper to provide integral means in place of the con~entional separate tape tab means, for securing the diaper around the infant.

l~lith continuirlg reference to the accompnnying dra~tings, wherein like reference numerals desi;gna-te sim;lar par-ts through-out the various views~ reference numeral lO generally designates an elas-ticized and contoured diaper constucted in accordance with the concept of the present invention~ The diaper 10 is o~ an hour-glass configuration f`or a cro-tch area 12 and four portions of` greater width defining ears 14, 16, 18 and 20~ The diaper includes a backing sheet 22 of an impervious polyethylene or the like~ A top sheet 24, pre-ferably of non-woven polyethylene or polypropylene fibers is secured to the backing sheet 22 along the peripheral edges o-f' the diaper 10 preferably with adhesive~ either hot mel-t or pressure-sensitive~ An absorbent pad 26 is disposed between the -top shee-t 24 and -the backing sheet 22 and rnay be of ~ioodfluff or the like. ',Jadding sheets may 'be provided as desired.
A pair of elastici3ed strips 34 and 36 are provided.
The backing shee-t 22 is coated with adhesive lines or spots 25 on its top sulface thereof and -the Stl-ipS 34 and 36, in stre-tched state,are thus bonded to the backing sheet 22 along the cro-tch portion 12 of the pad with a portion of each strip 34 and 36 thereof overlying the pad 26 and optionally en-tirely overlying -the pad a-t the ears 14, 16, 18 and 20. The strips 34 and 36 are secured by the adhesive preferably in the crotch area with the ends which overlie the ears 14, 16, 18 and 20 being free of attachment.
1~8~8S~
As shown in Fig. 2, elasticized members, in stretched sta-te 38 and 40 are bonded to the backing sheet 22 spaced ~rom the pad 26. Elasticized and water impervious barrier 42 (Fig.
4) is secured be-tween the backing sheet 22 and the -top shee-t 2 either by adhesive or hea-t sealing and serves to form a waist seal. Alternatively, (Fig.5) -the elasticized and water impervious waist member 4Li may be secured to the top shee-t as by adhesive thereby proving a waterproof waist seal against the skin of the infant to prevent moisture from seeping above the waist, such as when the infant is Iying down. As in Fig.
l, the ends of members 38 and 40 are preferably free of attachment, and may overlie the pad ears as well.
The elastic strips 38 and 40 e~tend at substantially righ-t angles to the elasticized strips 42 or 44 and are bonded to the backing sheet 22 with a slight initial tension thereon.
Thus, the strips 38 and 40 and the strips 42 or IL4 cooperate to place initial stress and stretch to the respective crotch seals and waist seal formed thereby and thus assure a more comfortable and better fit. The strips 38 and 40 and -the s-trips 42 and 44 are preferably made of a waterproof material further assuring fluid seals.
In Fig. 6, there is shown a modified form of the invention generally int~icated as reference numeral 70. Herein the diaper 70 is of generally hour-glass shape having a crotch portion 72 and ears 74, 76, 78 and 80. The diaper has the 5~
conven-tional backsheet, absonben-t pad and -top sheet arranKemen-t of the diaper of Fig. l Elasticized side members 82 and 84 are secured as by adhesive lines 75 to the backing shee-t at a loca-tion spaced from the pad 86 and likewise, elastici~ed waist member 88 (and optionally 90) i9 secured under tension as by bonding or adhesive to -the backing sheet spaced from the pad 86. The side members 82 and 84 serve to form crotch seals whi.le the waist member 88 serves to form a waist seal, and both serve to provide for secure and close fit of the diaper about the infant. The side members amd the waist member are preferably of a waterproof material. As in Fig. l, it is preferred to have the end of members 82 and 84 unattached and free of adhesive securement.
The side members 82 and 84 are spaced from 5 to 18 millimeters from the absorbent pad 26. The backing sheet i.s generally provided with spaced longitudinally parallel lines of adhesive to stabilize the pad on the back sheet. The side edges and top of the diaper assembly are secured as previously described.
~s shown in Fig. 7, the diaper may be convenie~y folaed with the ears, side members, and the like folded inward-ly to form a substantial.ly rectangular shape lO0 for convenience in packing and shipping.
In use~ as shown in Fig. 8, any suitable tabs which may be provided with self-stick adhesive and indicated at 102 8S~
may be used to hold -the diaper on the infant subs-tan-tially in the position as shown in Fig. 8.
In lieu of tabs 102, elastic waist member 88 (Fig.6) may be extended beyond the two side edges of pad 70 and the projecting portions provided with a sui-table adhesive (e.g.
pressure-sensitive) to provide means for securing the diaper about -the infant. The pro~ecting segments may be provided with suitable, removable release sheets to protec-t the adhesive before securement. Further, in place of "throw-away"
release sheet the diaper may be provided with a release sheet affixed to the diaper as described and shown in U.S. Patents 3,893,460 and 4,100,921. In this construction the pro~jecting end of the adhesive-coated elastic waist member is folded over so that the adhesive layer is in contact with the release surface of the release sheet.
It will be noted that in embodiment of Figs. 2 and 6, the elastic waist members lie between the topsheet and backsheet of the diaper but as shown in Fig. 5, elastic waist member(s) 44 may be over the topsheet. So similarly, where the elastic waist member pro,jects beyond the pad edges as described above, said waist member may also lie over the top sheet; still further, it may also be positioned on the back-side of the diaper (i.e. on the outside or external surface of the backsheet). In those instances where a permanently fixed release shee-t is used, said release sheet would be on the front surface (i.e. topsheet surface) of the diaper with s~
the adhesive on the elastic waist member adapted to con-tact the release sheet when the elastic waist member is fol~ed over in the "before use" condi-tion.
A still further modification lies in utilizing the back (or exposed) surface of the elastic waist member 3S -the release surface. This embodiment is particularly useful when the elastic wais-t member is secured to the front (top sheet) surface of the diaper, and in this construction the back surface of the elastic member (i.e. surface opposite that which is secured to the front surface of -the diaper) is zone coated or constructed to provide at the end thereof a pressure sensitive adhesive and ad~jacent said adhesive zone, a zone at least contiguous with said adhesive of a release nature.
