REUSABLE DIAPER WITH AIR-FILLED OUTER EDGES

Abstract: The invention relates to a refill diaper (1) consisting of two parts, namely an outer diaper (2) and an inner diaper (3). The outer diaper (2) does easily adapt its form to the form of the space between the legs of a child so that it assumes the same shape. It does include a continuous outer edge portion (4) which will contact the skin of the child and is air-filled to provide a sealed contact with the skin and a distance from motions in the diaper. The outer diaper prevents liquid from oozing out and it does include valves (9) permitting the diaper to respirate and in that way to let out moisture. The inner diaper (3) is constituted by a conveniently exchangeable expandable diaper, the shape of which matches that of the outer diaper (2).

Description: Reusable diaper with air-filled outer edges. The present invention relates to refill sanitary napkin or diaper consisting of two parts, namely an outer diaper and an inner diaper. The diapers today most frequent on the market are constituted by the type having an outer diaper integrated with an inner diaper made by absorbing material. Those diapers are, however, relatively expensive, for which reason there are in many cases still used plastic tip diapers, i.e. comprising a loose absorbing pad held in position on the child with the aid of a plastic tip. Both those types of diapers do, however, suffer from the drawback that emotions often stick to the bottom of the child and the diapers do not come in sealing contact with the legs of the child which results in leakage. Moreover, they are not non-polluting. The object of the present invention is to provide a diaper solving the above-mentioned problem and at which only the suction pad, that is an inner diaper, requires exchange whereas an outer diaper supporting the inner one can be re-used. The features characterizing the invention are set out in the claims. Thanks to the invention there has now been provided a refill diaper which in an excellent manner satisfies the requirements and in addition thereto is substantially cheaper than the prior art diapers because only the inner diaper has to be disposed and exchanged after use. Thanks to the design of the outer diaper which includes an air-filled edge portion in contact with the skin there is created a distance from motions in the diaper so that motions cannot stick to the bottom. Further, the just mentioned edge portion will remain in sealing contact with the skin of the child so that there will be no leaking. The diaper material which is constituted by a quick drying, partly air- filled, respirating foam plastic material does not let out any liquid but includes valves permitting the diaper to release moisture and to respirate . In order to retain the outer diaper and its inner diaper in position on the child there are provided flexible and adjustable soft bands which are crosswise secured to the front and rear portions of the diaper. The inner diaper is constituted by an exchangeable and expandable diaper attached to the outer one by means of a tape strip. The inner diaper is small and thin, absorbing and odour- neutralizing and enclose an indicator reacting the urine whereby there will on the front portion of the outer diaper appear an indication of urine presence. Also, the inner diaper can conveniently be removed from the outer diaper with the aid of a plastic strip and it can after use be flushed down in a water closet . The dimensions of the inner diaper are considerably smaller than those of expandable diapers today available and it is manufactured from non-polluting material . A preferred embodiment will now be described more in detail, reference being made to the drawings . Fig. 1 is a diagrammatic perspective view of refill diaper according to the invention as seen obliquely from behind . Fig. 2 illustrated the diaper shown in Fig. 1 as seen from above , Fig . 3 shows the diaper of Figs. 1 and 2 as seen in a lateral view. As appears from the drawings, the diaper 1 is according to a preferred embodiment of the invention constituted by two parts, namely an outer diaper 2 and an inner diaper 3. The outer diaper 2 can adapt to the form of the space between the legs of the child so that it will accurately match the shape thereof and it does include continuous outer edge portion 4 in contact with the child's skin. According to the embodiment illustrated the height of that outer edge portion 4 is about 2 cm and its width approximately 0,5 cm. The outer edge is filled with air in order to establish the above mentioned tight contact with the skin. The outer edge portion provides a distance from motions in the diaper 1 so that such motions can stick the bottom of the child. The contact between the outer edge portion 4 and the skin is sealing to such an extent that leakage is eliminated. The material of the diaper can be a quick drying, partly air-filled, respirating foam plastic. The diaper 1 does not release liquid but has valves 9, so that it can let out moisture and respirate . Diaper 1 is attached to the body of the child by means of adjustable, flexible, tensile, soft bands 5 and 6 which are secured to the lateral edge portions 10-13 of the outer diaper 2 resulting in the diaper being securely fixed in its proper position. The free outer ends 16,17 of band 5,6 can be detachably attached to the front portion 18 of the outer diaper 2 with the aid of burdock tapes or buttons, not shown in the drawing . Inside the outer diaper 2 there is an inner diaper 3 of expandable type which can conveniently be exchanged and the shape of which matches that of the outer diaper 2. The inner di per 3 can be retained in the outer diaper 2 by means of a tape strip and it includes an indicator 8 in the shape of a strip standing from the underside of the inner diaper 3 to somewhat over the front edge portion 4 of the outer diaper. The indicator 8 reacts with ammonium in the urine directly show that the diaper is wet, e.g. the way that the colour of indicator 8 has changed . Upon each change, or as often as required, the outer diaper 2 can easily be rinsed for re-use or it can be heated for sterilization. The inner diaper 3 is small and thin, absorbing and odour neutralizing and includes the above-mentioned indicator 8 making it possible conveniently to see that a child has urinated. The inner diaper 3 can also conveniently be removed from the outer diaper 2 with the aid of a plastic strip 7 which can support the indicator 8. Following this it can be flushed down in a toilet.

Claims: Claims 1. A refill diaper consisting of two parts, namely an outer diaper (2) and an inner diaper (3) , the outer diaper (2) being easily deformable to the shape of the space between the legs of a child so as sealingly to match said space, and also comprising a continuous outer edge portion (4) for contact with the skin of the child, characterized in that said outer edge portion (4) is air-filled for sealing contact with the skin and intended to uphold distance from motions in the diaper (1) , the outer diaper (2) preventing liquid from oozing out and comprising valves (9) permitting the diaper (1) to respire leting out moisture, the inner diaper (3) being constituted by a conveniently exchangeable, expandable diaper the shape of which is adapted t that of the outer diaper, the refill diaper (1) comprising means for retaining it in a fixed position on a child, constituted by at least two tensile, adjustable, soft bands (5,6) extending in bow-form from the lateral edge portions (10-13) of the outer diaper and intersecting each other so as to define opening (14,15) for the child's legs. 2. A refill diaper according to claim 1, characterized in that the free outer ends (16,17) of the bands (5,6) can be detachablt connected to the front portion (18) of the outer diaper by means of burdock tape locks or buttons . 3. A refill diaper according to claim 1, characterized in that the outer diaper (3) is manufactured from a quick-drying respirating foam plastic material containing air-filled cells. 4.
