Abstract

The invention concerns a nappy, this term being understood to mean both washable and reusable products. The aim of the invention is to provide a nappy which reliably prevents soiling and/or body fluids from escaping, ensures a high degree of comfort, has a high capacity to absorb fluids and is easy to handle, as well as being kind to the skin and fast-drying. This is achieved by virtue of the fact that the nappy comprises an outer layer (5) with an embeded absorptive layer (4) and on which a raised intermediate layer (3) with pockets on all sides is located such that there is almost no contact between the absorptive layer (4) and an inside layer (2), that the intermediate layer (3) surrounds the absorptive layer (4) to form a liquid-tight seal between the two and that the outer layer (5) is joined to the intermediate layer (3) to form a liquid-tight seal, the edges of the inside layer (2), the outer layer (5) and a prior art outer fabric being joined together by a seam extending the whole way round (20) to form a single element, and longitudinal elastic tapes (8 and 8') and an elastic transverse tape (9) being attached or sealed in such a way that the area of the join is imprevious to liquid.

Description

Pant diaper

The invention relates to a pant diaper, which should be understood to mean washable and therefore reusable products, for absorbing dirt and body fluids from small children or incontinent persons,

Washable diaper pants with or without inserts have long been known and in use, but have not yet become established because the moisture retention capacity is below that of the disposable diaper with polymer insert, there is insufficient moisture protection and there is no easy handling. The commercially available diaper pants according to DE-GM 91 02 591 have a built-in natural absorbent pad as inner pants and have a moisture barrier on the outside made of coated fabric, which is sewn around the edges with a fabric cover made of cotton or the like. This three-layer product, which the developer himself calls diaper pants, certainly only works with additional inserts in the pocket of the inner pants, the insertion process is relatively cumbersome. The said diaper pants have an inadequate leak protection, because liquid escaping from the inside pocket or the insert can bridge the moisture barrier and penetrate into the outer fabric covering via the seam with elastic band and coated fabric, so that, for example, clothing can be soaked. Furthermore, the leg end is hard and disturbing on the wearer.

DE-GM 92 03 756.9 protects a three- to four-layer pant diaper. In one embodiment, the known division into the outer skin, inner fabric and absorbent intermediate layer arranged between them is expanded by a polyester wadding layer between the inner fabric and intermediate layer. It is disadvantageous that moisture can escape at the seams of the outer layer, that moisture can escape on the sides and bridge the folded outer layer, and that rewetting can occur through the polyester wadding.

The invention specified in the protection claim 1 has for its object to provide a pant diaper in which the escape of dirt and / or body fluids is prevented safely and reliably, which has a high wearing comfort, a high fluid intake and easy handling and is skin-friendly and quick-drying is procured.

This problem is solved with the measures of protection claim 1. Further advantageous refinements are specified in the protective claims 2 to 19. With the invention in the specified application, known materials are used to create a new arrangement with a liquid-permeable inner layer, an intermediate layer, a suction layer embedded therein, a liquid-tight outer layer and an outer fabric, the inner layer, outer layer and outer fabric extending over the entire pant diaper surface and on their edges are firmly connected with each other. The inner layer prevents direct contact of the wearer with the absorbent and outer layers and additionally increases the wearing comfort by virtue of the fact that all possible diaper parts which produce pressure points lie beneath it and these points are reduced in their effect. The inner layer preferably has a gap-shaped opening in the rear area for the removal or insertion of the ends of the suction layer during the drying process from or into the pockets of the intermediate layer. This intermediate layer lies below the inner layer and is connected to the outer layer in a liquid-impermeable manner, is preferably rectangular and encloses the absorbent layer in a liquid-tight manner on its four erected sides. This uprighting creates a special advantage between the inner layer and the suction layer by lifting the inner layer from the suction layer, a drying zone. The suction layer is firmly connected to the outer layer in a liquid-impermeable manner on its two longitudinal sides, preferably in the central region. The ends are inserted unconnected into the pockets of the intermediate layer. They can be removed from these pockets to speed up the drying process. In order to increase the wearing comfort, the preferably multi-layer suction layer is predominantly hourglass-shaped, as a result of which rubbing beads between the legs of the wearer are avoided and the suction layer is in good contact. The lower layer, which is not hourglass-shaped, supports the desired spreading effect. Advantageous for a good fit of the pant diaper is the application of elastic bands in a straight line in the area of the leg end in such a way that they lie in the wearer's crotch and are not perceived as disturbing. They are attached or sealed liquid-impermeably at their connection points. To simplify production, it may be necessary for the elastic longitudinal bands to coincide with the outer side leg end of the pant diaper. This is particularly the case when the intermediate layer reproduces the basic shape of the pant diaper and the outer layer is designed to be smaller in its outer dimensions than the basic shape of the pant diaper for better processing. The outer layer and the intermediate layer have swapped their original shape; in no way have they reversed their assignment to each other.

For various applications, it makes sense if the pant diaper with the features described above, in particular the arrangement of the outer and intermediate layer, is firmly or detachably connected to items of clothing that are on the market or are coming onto the market. These are also special items of clothing for various disabilities.

The aforementioned inventive structure can of course also be adopted for disposable products that can be used once and with the appropriate choice of material. It is also possible that only the suction layer is designed as a disposable product.

An embodiment of the invention is explained with reference to Figures 1 to 5. Show it:

The pant diaper 1 shown in Figure 1 has a liquid-permeable inner layer 2, which extends over the entire inner pant diaper body and made of a textile fabric, preferably a knitted fabric made of synthetic yarns such as polyester, polypropylene, or consists of natural fibers. The inner layer 2 is fastened all around with the outer layer 5 and the outer fabric 6 at the edges of the pant diaper 1 via a connecting seam over everything 20 and preferably has a gap-shaped opening 17 in the rear area. For special applications, the inner layer 2 can be reduced to at least the area of the intermediate layer 3. Furthermore, the pant diaper 1 has the intermediate layer 3 according to the invention. The intermediate layer 3 is preferably of rectangular design according to FIGS. 2, 3 and 5 and has on its long outer sides on the inner edges elastic bands 7 and 7 'which are sewn onto the intermediate layer 3. The connection can also be produced by welding, gluing, vulcanizing or similar inseparable connection techniques in such a way that the long sides stand up and the short sides stand out from the outer layer 5 and form pockets 16. The intermediate layer 3 is firmly connected to the outer layer 5 in a liquid-tight manner by welding, welding, gluing, vulcanizing or similar inseparable connection techniques. The pant diaper 1 contains a suction layer 4 embedded in the intermediate layer 3, which, as shown in FIG. 3, is constructed in several layers and consists of a commercially available all-purpose fleece, the lower layer 13 preferably being rectangular for infants to support the desired spreading effect, the other layers 14 in an hourglass shape are formed, and is enveloped by a textile fabric 12. This is preferably made of cotton, but can also be made of synthetic yarns, such as polyester, and is point or line-shaped, preferably by sewing to all layers to stabilize the same and a fixing strip 15. This fixing strip 15 is connected on both sides to the underside of the suction layer 4, preferably in the central region thereof, preferably by sewing (connecting seam of the suction layer and fixing strip 19), namely longitudinally and liquid-tightly attached to the outer layer 5 by welding, welding, gluing, vulcanizing or similar unsolvable joining techniques. For special applications, the Suction layer 4 can also be detachably fastened to the outer layer 5, for example via Velcro fasteners. In another embodiment, the suction layer 4 can also be directly connected to the outer layer 5 in a liquid-tight manner.

The unconnected ends of the suction layer 4 are pushed into the pockets 16 of the intermediate layer 3 and can be pulled out via the gap-shaped opening 17 of the inner layer 2.

17 additional inserts can also be inserted through this opening.

Furthermore, in a preferred embodiment, elastic longitudinal bands 8 and 8 'are attached by sewing and sealed at their connection points in a liquid-impermeable manner. They are either impermeable to liquids on a connection area between the intermediate layer 3 and the outer layer 5, hereinafter referred to as the fixing track 18, on the outer layer 5 or intermediate layer 3 by welding, gluing, vulcanizing or similar insoluble

Connection techniques or outside the fixing track 18 to the edge.

In the embodiment according to FIG. 4, the elastic longitudinal bands 8 and 8 'are fastened on the intermediate layer 3 in such a way that they lie on the fixing track 18. In the embodiment according to FIG. 4a, the elastic longitudinal bands 8 and 8 'are fastened on the fixing track 18 on the inner side of the outer layer 5. In the embodiment according to FIG. 4 b, the elastic longitudinal bands 8 and 8 ^f are fastened on the outer side of the outer layer 5 in such a way that they also lie on the fixing track 18. In the embodiment according to FIG. 4c, the elastic longitudinal bands 8 and 8 'are fastened on the outer side of the outer layer 5 outside the fixing track 18. In the embodiment according to FIG. 4d, the elastic longitudinal bands 8 and 8 'are fastened on the intermediate layer 3 in such a way that they lie outside the fixing track 18. In the embodiment according to FIG. 4e, the elastic longitudinal bands 8 and 8 'are fastened on the inner side of the outer layer 5 outside the fixing track 18. In other versions, the elastic longitudinal bands 8 and 8 'can be directly, for example by welding, welding, gluing, Vulcanizing or similar joining techniques can be applied.

At the rear end of the pant diaper, an elastic cross band 9 is fastened between the inner layer 2 and the outer layer 5 on the edge of the pant diaper, preferably by sewing.

The pant diaper 1 is closed with a commercially available Velcro tape, the Velcro fastener part 10 on the outer fabric 6 and the Velcro fastener part 11 is attached to the inner layer 2.

To simplify production, it may be necessary for the elastic longitudinal bands (8, 8 ') to coincide with the outer side leg end of the pant diaper. This is particularly the case when the intermediate layer (3) reproduces the basic shape of the pant diaper and the outer layer (5) is made smaller in its outer dimensions than the basic shape of the pant diaper for better processing. The outer layer (5) and the intermediate layer (3) have almost reversed their original shape; in no way have they reversed their assignment to each other.

For various applications, it makes sense if the pant diaper with the features described above, in particular the arrangement of the outer layer (5) and intermediate layer (3), is firmly or releasably connected to items of clothing which are on the market or are coming onto the market. These are also special items of clothing for various disabilities.
