Abstract
ABSTRACT OF THE DISCLOSURE
A disposable diaper or like product comprising, in order, a top sheet of hydrophobic non-woven fibers which overlies an absorbent pad about which is wrapped a thin tissue wadding of non-woven hydrophobic fibers. The disposable diaper is provided with a water-impervious backing sheet. The hydrophobic wadding provides considerable strength which does not deterior-ate when fluid is absorbed by the absorbent pad and serves to prevent fluid wetback.

Description
~ ~ ~ 3 ~ ~J
BACKGROUND OF T~E INVENTION
. ~
FIELD OF THE INVENTION
This invention relates to disposable products~ such as diapers, sanitary pads, and the like, and more particularly to a disposable diaper having a we~ strength hydrophobic tissue waddin~ for preventing fluid we-tback while maintaining the shape of the absorbent pad.
DESCRIPTION OF Tl-IE PRIOR ART
Disposable diapers having an absorbent pad formed of a core of wood fluff or like material are well known. These pads have been used with and provided with a tissue wadding which, in the past, has been of highly fluid permeable and fluid absor-bent material. Waddings have been used to wrap the absorben-t pad, but the tissue wadding when we-t loses strength and, ;n use, -the pad often loses shape, absorbing qualities, and permits an unwanted degree of flu:id wetback.
Attempts have been made to provide a barrier to the 1uid wetback, such as the barrier layer shown in the patent to John Michael Hernandez, No. 3,987,792, for Disposable Diaper Having Improved Liquid Retention. However, the hydrophobic fibers of the barrier layer of this prior patent form a rela-tively thick resilient fibrous pad and because of the difficulty of penetration thereof, a water pervious top layer having fluid feeding openings therein must be used.

According to the inven-tion~ there is provided a disposable diaper comprising, in order, a top sheet of hydrophobic non-woven fibers capable of passing fluid but not absorbing the fluid, an absorben~ pad having a wrapping there-about of a tissue wadding formed of hydrophobic non-woven material for retaining the shape of the pad while resisting fluid wetback, said top sheet and said tissue wadding being formed of fibers of polyethylene or polypropylene or a combination thereof, a water impervious backing sheet, and means holding said diaper in assembled condition. The tissue wadding being of hydrophobic nature tends to retain its full strength even after fluid has passed into the absorbent pad. The wadding cooperates w:ith the top sheet in preventing fluid wetback, thus providing a dry surface in contact with the skin of the user.
Accordingly, the present invention is directed to provide a disposable diaper having means to retain the shape of the absorbent pad and which eliminate to a high degree fluid wetback.
Furthermore the invention provides a disposable diaper which has a high degree of resistance to fluid wetback yet does not re~uire a thick barrier layer, thereby providing a maximum amount of absorbing material while limiting the bulk and si~e o the diaper. Thus the invention utilizes a structure of two thin layers of hydrophobic non-woven material to reduce fluid wetback and maintain an infant using the disposable diaper in a dryer condition.
Other advantages and features, which will become apparent as the following description proceeds, are attained by this disposable diaper, preferred embodiments of which have been illustrated in the accompanying drawing, by way of examply only, wherein:
Figure 1 is an exploded perspective view of a diaper : ,

33~2 ~ ith continuing reference to the acc~mpanying drawing, wherein like reference numerals designate similar parts throughout the various views, reference numeral 10 is used to generally designate a disposable diaper constructed in accordance with ~he concep~s of the present invention. The diaper comprises, in order, a top sheet l2 formed of non-woven hydrophobic fibers of polyethylene or polypropylene or a combination thereof. This layer is water pervious, but not l~ater absorbing, and permits passage of waste fluid toward the absorbent pad 14, which is separated from the top sheet 12 by a tissue wadding of hydrophobic non-woven fibers, preferably of polyethylene or polypropylene, or a combination thereof.
A wadding 18 overlies the pad which sits on a water impervious backing sheet 20 formed of a suitable synthetic plastic material, such as polyethylene film. The backing sheet is folded over the top slleet 12 at 22, and secur0d thereto to hold the diaper in assembled condition. Adhesives, heat sealing, embossing or other means may be used for assembly purposes.
The core 14 is preferably formed of a wood fluff or tissue layers of paper-like material, which are highly absorbent. This material, when subjected to stress, will readily distort. In order to assure the shape of the pad, a tissue wadding 26 may be wrapped about the pad 14 in lieu of the wadding sheets 16 and 18.
The wrapped wadding 26 maintains the shape of the pad by pro-viding a high strength wrapping because this hydrophobic material has a very good degree of wet strength and in fact does not absorb fluidJ thereb-y not becoming weakened by the passage of fluid therethrough. The hydrophobic material resists fluid wetback and in conjunction with the hydrophobic top sheet achieves a high degree of resistance to fluid wetbackJ even though the material will readily pass fluid into the pad 14. This is because the wadding, unlike the tissue waddings of the prior art, does not absorb fluid.
Various changes and modifications of the disposable product are contempla~ed within the scope of the appended claims. f
