Wauberg, Palatine, Ill., assignor to The .Kendall Company, Boston, Mass, a corporation of Massachusetts Filed Sept. 25, 1964, Ser. No. 399,202 17 Claims. (Cl. 128287) ABSTRACT (IF THE DISCLOSURE A disposable diaper having a pouch at the back side of the diaper wherein the body of the diaper constitutes a wall of the pouch. The back surface of the diaper is impervious to the flow of fluids to prevent strike-through of fluids absorbed in the diaper. The pouch can be manipulated without contact with the front surface of the diaper to turn the pouch inside out so that the front absorbent surface and any body excrements thereon and fluids absorbed in the body of the diaper are disposed to the inside of the pouch, thus bagging the diaper for sanitary disposal thereof.

This invention relates to disposable absorbent articles and in particular to absorbent articles for the collection of body excretions and exudates. Examples of disposable absorbent articles to which this invention relates are disposable diapers, sanitary pads, wound dressings and the like. The invention will be described with particular reference to disposable diapers, from which the applicability of the invention to other disposable absorbent articles shall become apparent.

Disposable diapers are preferably provided with an impervious back surface. The back surface of the diaper is the surface opposite the surface of the diaper to be placed against the body. The impervious back surface serves to prevent seepage of liquid collected in the absorbent body of material of the diaper. This eliminates the need for a separate covering garment such as baby pants usually employed as a protection against strikethrough in the case of other diapers. Diapers constructed with an impervious back surface are particularly preferred for use at times when washing facilities are not readily accessible or at times of limited storage conditions, for example when traveling with infants. The impervious back side of the diaper may be a thin plastic sheet which also serves as a reinforcing component of the diaper.

Disposable diapers are suitable for a single use, after which they are to be discarded. Disposal of the soiled diaper immediately after removal may not be convenient. Furthermore, disposal of the diaper or the fluid absorbent portion of the diaper in flush toilets may not be desirable, in fact may be prohibited in many instances. The front surface of the diaper (the surface to be placed against the body) usually comprises a fluid pervious sheet covering the absorbent filler material of the diaper. This cover sheet has sufficient wet strength so that it does not disintegrate under use. Because of its wet strength properties it may cause some difliculties in sewage disposal systems, for example in septic tank systems. It is for this reason that soiled disposable diapers are instead discarded in trash containers until they can be disposed of permanently through other refuse disposal systems. Although stored only temporarily in a trash container, the unsanitary aspect to this is a drawback to the use of disposable diapers. It is also not always convenient in changing diapers to handlethe soiled diaper during removal and discard the same in a sanitary manner.

It is an object of this invention to provide a disposable diaper, as an example of a disposable absorbent article,

that may be handled conveniently in a sanitary manner. A specific object of this invention is a disposable diaper that may be handled during removal thereof without contact with the soiled surface of the diaper. Further in accordance with the objects of this invention is a diaper that may be handled for sanitary removal and immediately after removal be contained with a protective covering over the front surface of the diaper. Another object of this invention is a disposable diaper that may be protectively covered to prevent contamination by the contents of the used diaper. Another object of this invention is a diaper that may be handled during removal after use and protectively covered in a simple, eflicient and sanitary manner. Also among the objects of this invention is a disposable diaper in which the surface thereof to be placed against the body may be protected against contamination prior to use.

In general, the absorbent article of the invention comprises a fluid absorbent body and a pouch integrate therewith. The absorbent body, as in the case of a typical disposable diaper, is composed of a fluid absorbent filler material sandwiched between the front and back surfaces of the body. The absorbent filler material may be one or more plies of cellulosic sheeting, e.g., paper or nonwoven fabric, or a mass of loosely associated fibers such as cotton fibers or comminuted wood pulp commonly known as fluff (preferred for reasons of economy). The cover sheet providing the front surface of the absorbent body may be a fluid pervious sheet of any suitable material having sufficient dry and wet strength to resist rupture when subjected to forces encountered under normal conditions of wear. The cover sheet may be a wet strength tissue paper, nonwoven fabric or an applique sheeting of scrim having short length fibers adhesively bonded thereto. The impervious back surface may be provided by an impervious sheet of any suitable supple material, thin plastic sheeting being preferred in particular in the case of the disposable diapers of the present invention.

In accordance with this invention the back surface of the absorbent body of the diaper forms a portion of the pouch wall. The remainder of the pouch wall is an impervious sheet of material overlying the back surface and forming with the back surface opposing pouch wall portions defining the pouch cavity at the back side of the diaper when in use. Upon removal of the diaper after use the pouch may be easily manipulated to reverse upon itself, i.e., be turned inside-out, to thereby provide a sanitary cover enveloping the soiled surface and absorbent body of the diaper. The back side surface of the diaper previously opposing remaining wall portion of the pouch and serving to prevent fluid strike-through when in use then forms a portion of the outside surface of the pouch and with the remaining pouch wall portion forms a sanitary container for the used diaper.

The invention will now be described in detail with respect to disposable diaper embodiments thereof shown in the drawings, in which:

FIG. 1 is an exploded view of the components of a typical diaper constructed in accordance with this invent-ion;

FIG. 2 is a view in perspective of a diaper from the back or pouch side of the diaper before use;

FIG. 3 is a perspective view of the diaper of FIG. 2 from the front side of the diaper;

FIG. 4 is a cross-sectional view of the diaper of FIG. 2 taken along the line 44;

FIG. 5 is a perspective view of the diaper of FIG. 2, 3 and 4 to illustrate the general shape of the diaper when in place on the infant;

FIG. 6 is a view of the diaper of FIG. 5 after removal from the infant and in the process of being bagged;

FIG. 7 is an exploded view of an alternate diaper construction of this invention;

FIGS. 8,. 9 and 10 are cross-sectional views of diapers having pouches at the back side of the diaper when in use;

FIG. 1 1 is a view of a diaper from the back side showing a pouch formed in conjunction with a portion only of the back side.

For convenience the same components of the diapers shown are identified by the same number throughout the drawings. The numeral 1 designates the diaper generally. As in conventional disposable diapers the fluid ab sorbent body of the present diaper may comprise a fluid pervious front sheet 2, a bat of fluid absorbent fibers 3 and an impervious back sheet 4. As shown in FIGS. 1-3 the cover sheet, bat and back sheet may be of generally rectangular shape, the rectangular dimensions of the cover sheet 2 and back sheet 4 being slightly greater than that of the hat. The edge port-ions of the back and cover sheet extending beyond the edges of the bat are joined together to .encase the absorbent fibrous bat 3 between the cover sheet 2 and the back sheet 4. The joining of these two sheets atthe edges along the width at one end thereof is shown at 6 in the drawings.

Various modifications are possible in the construction of the absorbent body portion of the diapers of this invention. For example, the longitudinal edges of the cover sheet 2 may be folded around the corresponding adjacent edges of the bat 3, in which case the'width of the back sheet 4 need not be greater than the width of the bat. In this case the longitudinal edges of the back sheet are joined to the folded around longitudinal edges of the cover sheet 2. This relationship between the back and cover sheets is shown in FIG. 9. Alternatively, the longitudinal edges of the back sheet 4 may be folded around the adjacent edges of the bat 3. In this case the width of the cover sheet 2 neednot be greater than the width of the bat and is joined at its longitudinal edges to the edges ofthe back sheet. 4 folded around the batS. This relationship is shown in the cross-sectional view of the diaper of FIG. 8, which is a diaper assembled from the components shown in FIG. 7. When the impervious back sheet is a thin film of thermoplastic material, as is preferred,

joining of the edges thereof to the cover sheet, and to the absorbent fibrous material 3, if desired, may be accomplished by heat sealing techniques. Examples of suitable thermoplastic films for back sheets are polyethylene films, polypropylene films, ethylene-acrylate oopolymer films, ethylene-propylene copolymer films, and vinyl chloride polymer and copolymer films. It will be apparent to those in the art that the construction of the diaper thus far described is generally representative of conventional disposable diaper construction. It is an advantage of this invention that conventional diaper construction may be employed in the manufacture of the diapers of this invent-ion.

Referring to the first sheet of the drawings and specifically FIGS. 24, a pouch is formed integrate with the diaper by joining the impervious sheet '5 at its longitudinal edges and one of its edges along the width thereof to the corresponding adjacent edges of the back sheet4 forming the impervious back surface of the absorbent body of the diaper. The sheet 5 may be a film of thermoplastic material as in the case of the back sheet 4 and be joined thereto by heat sealing, as shown at 7. It should be noted that the seal at 7 is a tri-ply laminate of edge portions of the cover sheet 2, back sheet 4 and overlying sheet 5 and that the seal at 6 is a two-ply laminate of edge portions of sheets 2 and 4, as shown in FIGS. 24. The impervious sheet 5 overlies the back sheet 4 forming opposing pouch walls defining a pouch cavity 8 therebetween located at the back side of the diaper when the diaper is ready for or in use "as shown in FIGS. 2, 3 and 4.

The form of the diaper when in use and the relative position of the various component parts are shown in 4 FIG. 5. The cover sheet 2 is inside the diaper for contact with the body of the baby. The saled longitudinal edge 7 at the right as viewed in FIG. 2 is the edge 7 at the opening of the diaper for the .babys diaper leg shown in FIG. 5. The sealed bottom edge 7 as viewed in FIG. 2 is shown at the top rear and sides of the diaper as viewed inFIG. 5. The impervious sheet 5 is on the outside of the diaper. This sheet, being unattached to the back side 4 of the diaper except the edges thereof as aforedescribed, can move with respect thereto. In being capable of such movement the sheet 5 can slide against the sheet 4 in much the same manner as an outer garment slides against an under garment thus providing greater comfort to the wearer. The opening to the pouch cavity 8 is at the top front of the diaper as illustrated in FIG. 5.

The opening of the pouch cavity 8 is readily accessible during removal of the diaper for manipulation to turn the pouch inside-out and thus bag the soiled portions of the used diaper. The action of bagging the soiled portions of the diaper is shown in FIG. 6. The right hand is shown in the act of being withdrawn from the pouch cavity 8 while grasping the back side of the absorbent body of the diaper at the back sheet 4. The left hand is shown'reaching under the impervious sheet '5 and grasping the sheet at its unsealed edge. The left hand may be moved Sill'llll'. taneously in a direction generally opposite to the direction of movement of the right hand until the pouch is turned inside-out. In so doing, the impervious sheet 5 is moved into a position overlying the soiled surface of the.

diaper. The surface of the impervious sheet 5 that faced exteriorly of the diaper when in use as shown in FIG. 5 is now the interior surface of a pouch and is the surface of a wall portion thereof opposing the soiled'surface of the fluid pervious cover sheet 2. Thus, the pouch wall surfaces are reversed in providing a covering envelopment for the soiled fluid pervious surface and absorbent material of the diaper. For convenience, the pouch formed common with a surface portion of the absorbent body in accordance with this inventionshall be referred to herein and in the claims as a reversible pouch.

It will be readily appreciated that the act of containing the soiled portions of the diaper in the reversed pouch can be done conveniently and easily as part of the diaper change. The baby need not be left unattended while plac= ing the soiled diaper beyond reach of accidental contact. The diaper can be bagged within itself, so to speak, with= out touching the soiled surface of the diaper. The reversed pouch with the soiled portion inside the pouch may be sealed by twisting or folding over the edges of the pouch wall at the opening thereof to control escape of unpleasant odors from the soiled diaper during storagepend' ing eventual disposal.

Advantageously, the impervious back sheet 4 and'overlying sheet 5 may be constructed from a continuous, single-piece sheet such as a tubular section of polyethylene that may be formed by Well .known extrusion and blowing methods. The components of a diaper of this construction are shown in FIG. 7 prior to assembly wherein the numeral 9 designates a section of polyethylene tubing,-

ous cover sheet 2 as previously described to encase the absorbent material 3 therebetween. The other side 5 of the flattened tubular polyethylene is equivalent to the impervious sheet 5 shown in FIGS. 2-4 and need only be sealed to the opposing side 4 at one edge thereof, for example at the bottom as viewed in FIG. 7

FIG. 8 is a cross-sectional view of a diaper assembled from the components shown in FIG. 7 in which the longitudinal edges of the tubular polyethylene section are folded around the corresponding edges of absorbent material 3 and sealed to the cover sheet 2 along the longitudinal edges thereof.

FIG. is sectional view taken across the width of a diaper and FIG. 11 is a planar view of a diaper in each of which a portion only of the back side of the absorbent body forms an opposing wall portion of the pouch. In these cases the portion of the pouch wall formed by the impervious sheet 5 need not be coextensive with the back sheet 4 of the diaper. In the diaper of FIG. 10 the pouch is located substantially centrally between the longitudinal edges of the diaper, The sheet 5 may extend along the entire length of the diaper or a portion thereof. In the diaper of FIG. 11, the pouch is located-at one end of the diaper. In each case the dimensions of the overlying sheet 5 are chosen to provide a pouch of suitable size upon reversal to contain the entire soiled diaper surfaces.

It will of course be understood that the present diapers may be sold in the reversed pouch form. In this form the front surface of the diaper to be placed against the body may be kept sanitary prior to use. If desired, the inside surfaces thereof may be sterilized and the open end of the reversed pouch temporarily sealed to maintain sterility. The open end may be temporarily sealed by means of a pressure-sensitive adhesive, for example, which may remain in place after the pouch is turned inside-out to locate the pouch cavity at the back side of the diaper when in use. After use of the diaper and reversal of the pouch the adhesive may be used to again seal the reversed pouch.
