Single use ippa. - Engängsblöja.

The present invention relates to a disposable diaper having a fluid impermeable protective film, a fluid permeable nonwoven cover and a suction between the protective film and the nonwoven cover, as well as sealing strips and side flaps forming the outer edge which are connected to the nonwoven end.

It is generally known that disposable diapers thus obtained receive infant and incontinent stools 10 such that, after irrigation, these individuals will not feel any discomfort as the diaper suction body will completely receive the liquid. Covered skin. not only subjectively but also objectively dry, because the suction cup keeps fluid away from the surface of the skin. This is desirable so that the skin is not irritated by the excreted fluid since the clogged space has a particularly favorable climate for bacteria and microbes. However, it has been found that, for convenience, the user of these diapers after defecation, especially for a recoverable infant or larger child, does not see any reason to look for a defecation need when detecting a toilet. This results in the fact that due to the lack of learning effect, getting used to normal toilet visits 20 is either very late or not at all in the case of morbid incontinence.

It is therefore an object of the invention to further develop such a diaper such that it achieves a learning effect, which results in the incapacitated 25 persons and children learning to strive for the toilet.

According to the invention, this object is solved by the side flaps being formed of a hydrophilic material and extending past the sealing strips at least a portion of the length of the sealing strips and outwardly of the longitudinal edges of the diaper 30 when using the diaper 30.

The side flaps, though well known in the art (EP 0 219 326), are nevertheless intended to hold the fluids secreted in the jacket securely within the jacket such that they cannot protrude from the side edges. Thus, such side flaps are not formed as sealing strips.

F1494922 also discloses a diaper having side flaps on the inside of the longitudinal-5 full edges of the diaper and forming buffer elements including elastic members. These flaps do not extend outwardly but inwardly to raise their inner edges against the wearer's skin.

In the disposable diaper of the invention, the side flaps have the function of directing a portion of the 10 fluid out of the diaper. These side flaps thus override the sealing strips. The defecation fluid is drained so that the side flaps are directly connected to the nonwoven casing to which the effluent first touches. Thus, immediately after defecation, some of the fluid is discharged from the jacket. The speed depends on the absorbency of the side flaps. If the portions of the side flaps protruding from the diaper are moistened with liquid, the incontinent then develops an unpleasant sensation when this moistened portion of the side flaps comes in contact with the skin surface. Usually, some of the liquid evaporates in the side flaps, whereby the side flaps are cooled due to the heat of evaporation. However, the user perceives this coldness as an unpleasant feeling. Gradually, then, the uncomfortable sensation is combined with fluid secretion. These individuals can then be taught that by using the toilet, the unpleasant cold effect will no longer occur because the liquid is no longer secreted into the diaper. Thus, the diaper of the invention has the advantage that the skin surface covered by the diaper does not come into contact with the secreted fluid since it is kept away from the surface of the skin, but nonetheless the incapacitated person learns to hold his or her feces.

The hydrophilic side flaps preferably extend over the outer edge of the sealing strips at the foot recesses. This provides the advantage that the side flaps, which due to the hydrophilic property, absorb moisture from the interior of the jacket, no-30 distribute at the point of motion on the inner surface of the upper arms. However, this area of the body is particularly sensitive. Even slight differences in temperature relative to the environment are known to be unpleasant. Thus, even the smallest amounts of fluid withdrawn from the diaper space are known to be disturbing. Since the side flaps extend over the diaper only at the feet 106774 3, but are nevertheless connected throughout its length with the nonwoven cover, the effect of the cortex and thus the time to suck up a portion of the liquid is independent of where the liquid is discharged into the diaper.

In another embodiment, the side flaps are arranged only at the foot recesses. The side flaps do not extend over the entire length of the diaper, but are arranged only at the point where the effluent mainly hits. In this embodiment, the side flaps have a smaller length and thus the diaper can be made more economically.

10

In another embodiment, the side flaps extend over the entire length of the diaper. Ic. This has the advantage that the side flaps can be fitted simply because they are rolled from the endless strip and likewise fitted to the diapers which are still in the endless strip and welded therewith and can also be separated with them.

In a preferred embodiment, the side flaps are optionally connected in one piece with a nonwoven cover at a certain point where it covers the suction body. This has the advantage that liquid absorption of the side flaps 20 occurs not only from the nonwoven fabric but also from the suction body. However, if the liquid so formed is unilaterally discharged into the non-woven fabric cover in the thus formed diaper, it will fall on both side flaps, since the liquid is distributed evenly within the diaper through the suction nozzle and thus at both side flaps.

25

In a particular embodiment, only one side flap is arranged on one side of the diaper.

Preferably, the side flaps are absorbent with respect to the fluid or the side flaps have a coronary action. Thus, the liquid is discharged relatively quickly out of the diaper space onto the skin surface of the carrier. By selecting the material, density or possibly surface treatments, the suction rate can be adjusted to the desired value range.

4, 106774

In a further development, the side flaps, when the diaper is leaning against the body, extend out of the diaper. Preferably, the side flaps rest against, or at least partially contact, the inner surface of the user's leg.

A suitable material for the side flaps is viscose, however other suitable materials may be used.

The side flaps are preferably glued onto the nonwoven cover. This can be done, for example, with hot or hot melt adhesive already during the manufacture of the diaper.

Other advantages, features, and details of the invention will be apparent from the following description, in which reference is made, in particular, to particularly preferred embodiments of the invention. The described features may be achieved individually or in desired combinations in the context of the invention.

Figure 1 is a top view of a half of a diaper having a side flap arranged in a foot notch.

Figure 2 is a top view of a half of a diaper having a side flap extending over the entire length of the diaper.

Figure 3 shows a section III-III along the center line of Figure 1 or 2.

Figure 1 is a top plan view of the jacket designated 1 in its entirety, with only the half to the right of the longitudinal center line 2 being shown. This sheath 1 is provided with a protective film 3 on its lower surface and a nonwoven cloth cover 4 on its upper surface, as is clearly apparent from Figure 3. Between the protective film 3 and the nonwoven cloth cover 4, there is a suction piece 30 5 which completely absorbs the liquid entering the diaper 1. The protective film 3 is impermeable to liquids and consists of e.g. polyethylene or polypropylene. The sheath 1 has a foot door 10 between the trailing edge portion 7, which is provided with nonwoven fabric elements 8, and the front edge portion 9, and the foot door 10 may have any desired shape and the invention is not limited to the shapes shown. In addition, a side flap 11 can be seen, which along its longitudinal edge 12 is connected to the nonwoven cover 4, e.g. by gluing 13. The opposite longitudinal edge 14 of the side flap 11 extends beyond the longitudinal edge 5 15 of the diaper 1 and thus also over the foot 10. In the embodiment illustrated in Figure 1, the side flap 11 is formed trapezoidally, with the narrower longitudinal edge 14 extending generally over the sealing strip 16 formed by the edge of the protective film 3 and the edge of the nonwoven cloth 4.

In the embodiment shown in Fig. 2, the side flap 11 has a rectangular shape and extends from the trailing edge portion 7 to the leading edge portion 9, wherein also in this embodiment one longitudinal edge 12 is joined by a glue joint 13 to a nonwoven cover 14. In the embodiment shown in Fig. 2, foot pedal 10 has an adhesive 15 outside the suction body 5, whereas adhesive 13 in the embodiment of Fig. 1 is located at suction body 5.

In the section shown in Fig. 3, a protective film on the underside of the diaper 1, a nonwoven cloth top forming a top surface 4 and an inlet suction piece 5 are visible along the line III-III in Fig. 1 to form a sealing strip 16 on its edge. The sealing strip 16 has a side flap 11 whose longitudinal edge 12 is glued with a nonwoven cloth cover 4 above the suction cup 5 and whose longitudinal edge 14 extends freely over the sealing strip 16. With this side flap 11, 25 fluids can now be discharged from the housing past the sealing strip 16. If air flows through the portion of the diaphragm of the side flap 11, a portion of the absorbed liquid is vaporized and the side flap 11 becomes cold due to the heat of vaporization, which the incontinent person feels uncomfortable. The side flaps have the function of a fluid indicator.

The side flaps 11 may have one or more elastic members to provide better support against the user's upper leg.
