Definitions

  • the present invention relates to a diaper system of the type disclosed in WO 94/15563, i.e. a diaper system in which there is made use of reusable, washable textile diapers or wrappers and diaper inserts in the form of absorbent dispos ⁇ able units made so as to be flushable in the toilet.
  • the washable dia ⁇ per is made with a pocket or folding flap for encasing a pa- per wrapped diaper insert pad in such a manner that the pad will then be separated from the skin by one or more layers of a liquid permeable, but non-absorbing material, whereby it is achieved, as well known per se, that the absorbent material may be or become wet without being felt wet against the skin.
  • This system is advantageous over the otherwise predomi ⁇ nantly used disposable diapers in that the current consump ⁇ tion can be limited to the insert pads and in that the public waste systems will be loaded to a reduced degree, while also the textile diapers are more user friendly than the dispos- able plastic diapers. It remains as a drawback that the tex ⁇ tile diapers should be washed, but this has been found ac ⁇ ceptable in view of the advantages.
  • the liquid permeable, but non-ab ⁇ sorbing fabric to be an element which is not coherent with the textile diaper, viz. either as a high quality element, which is usable as an independent wrapping member for the in ⁇ sert pads, or as a lower qualified, i.e. cheaper, but still efficient wrapping member associated with each of the indi ⁇ vidual consumption products as constituted by the absorbing pads.
  • the textile diapers can be manufactured without the said pocket or flap and that they will not need to be washed as often as other- wise envisaged, this here being explained in more detail for each of the two instances: 1) .
  • casing In connection with the invention it could be acceptable that such a casing be flushed in the toilet, but it may be prescribed that it should be dropped in a waste container such as a waste bin or bag next to the closet.
  • a waste container such as a waste bin or bag next to the closet.
  • the casing is transferred to the waste system for solid household waste, but only by an amount of some one gram per unit, this being much less than for conventional disposable diapers.
  • the casing material here considered may be identical with the material typically used for the innermost layer in disposable diapers, i.e. in advance a fully accept ⁇ able material.
  • the textile diaper there is no superior requirement as to any special design of the textile diaper, though the latter may suitably be provided with a receiver compartment for the said insert pads, preferably limited between projecting ⁇ crutch barrier strips' at the sides and short front and rear holding flaps for the pad ends.
  • a receiver compartment for the said insert pads preferably limited between projecting ⁇ crutch barrier strips' at the sides and short front and rear holding flaps for the pad ends.
  • Such a product will be co - prised by the invention, preferably also including a moisture barrier layer of such a known material which allows for 'breathing' through the layer, but no moisture penetration.
  • the pads can be used with quite simple textile wrappings, so there is good reason to focus on the articles of trade as constituted by the dis ⁇ cussed insert pads:
  • the pads identified above under 2) should be made in such a manner that the casing for the absorbing material has a gripping end portion, which can be used for pulling out the pad from the receiver area of the textile diaper for enabling the user to hold the pad in a hanging position above a closet bowl, e.g. held in a carrier string.
  • the opposite end of the casing should be easily openable, if closed at all, e.g. in that the casing at this end is closed only by a short folding over, such that the interior absorption material, now heavy by absorbed liquid, can freely fall out of the casing and down into the closet bowl. The user may then, by simple move ⁇ ments, move the hanging, emptied casing to be dropped into an ordinary waste bin or bag next to the closet bowl.
  • the pads identified above under 1) should, as articles of sale, not be surrounded by any casing, as the latter will be constituted by the washable and reusable wrapping fabric pieces.
  • manufac ⁇ ture pad members only consisting of scantily coherent fibre plates or flat pads, e.g. having only a single layer of toi ⁇ let paper material at both sides and no coverage along the edge sides, i.e. without the fibre pads being fully enclosed.
  • sales units will be dis ⁇ tinctly adapted to be enclosed in a wrapping of a non-absorb ⁇ ing type, and in principle this will apply whether the sales units are intended for use as diaper pads for babies or as sanitary elements for women.
  • Fig. 1 is a perspective view of a folded out diaper wrap ⁇ ping according to the invention
  • Fig. 2 is a corresponding view of an insert pad usable therein;
  • Fig. 3 is a corresponding view of a modified insert; and Figs. 4 and 5 are perspective views of loose insert units.
  • Fig. 1 shows a diaper wrapping 2, which, in principle, may be any arbitrary piece of textile, yet preferably made as a fashioned diaper unit with broad front and rear ends 4,6 and an intermediate, narrower crutch portion 8, along which the diaper is provided sewn on, upright crutch barrier strips 10 at the sides, while at the ends of these strips there are secured end pocket flaps 12.
  • the diaper 2 comprises two soft textile layers 14 and 16 with an intermediate layer 18 of a known, watertight material capable of breathing.
  • the parts 10 and 12 delimit a receiver area 20 for an ab- sorbing insert pad 22, e.g. as shown in Fig. 4, which can be mounted loosely between the barrier strips with its opposite ends laid under the pocket flaps 12.
  • these pads 22 may be produced in different manners, simplest as shown in Fig. 2 which shows a sales ar- tide 23 in the form of a plate element 24 of loose fibre ma ⁇ terial covered by layers 26 of toilet paper on its flat sides.
  • the pad article could consist solely of the absorbing fibre plate 24, if the fibres are just weakly bonded, but with the use of the cheap cover layers 26 the product can be made with an extremely low degree of fibre bonding, such that it will be very readily disintegratable when later on thrown into the closet.
  • To the diaper 2 may belong one or more loose wrapping sheets 28, Fig. 3, consisting of a non-absorbing, liquid per- meable fabric for use, by the user, as a wrapping for the in ⁇ sert pad according to Fig. 2 prior to placing the same in the receiver area 20.
  • the fabric pieces 28 are suitably provided with a string or tape 30, which can later on be used for pulling out the wrapped unit from the diaper pocket and for hangingly carrying of the unit above a closet bowl.
  • the fab ⁇ ric piece 28 should only be loosely wrapped about the pad member 23, e.g. by simple folding at the ends, whereby, after removal from the diaper, the liquid soaked pad member may easily make its way downwards from the package hanging in the string 30, for delivery to the closet bowl.
  • the emptied fabric piece 28 can be laid to be washed, if required together with the diaper 2, but as men ⁇ tioned it will quite often be sufficient to wash the fabric piece 28 which, due to its non-absorbing character, is very easy to wash and dry.
  • wrapper fabric pieces 28 en ⁇ tirely and instead use commercially produced pad elements which, as shown in Fig. 5, may consist of a fibre pad accord- ing to Fig. 2, enclosed in a casing 32 of a thinwalled, cheap material with the same basic properties as the wrapper pieces 28 and having at one end a pull string 30, while at the other end being open or just closed by a simple over-folding 34.
  • this element Once this element has been exposed to liquid in the dia ⁇ per 2, it can be lifted out for an easy fall down of the fi ⁇ bre core in the closet while small faeces, if any, at the outside can be brushed the same way. Thereafter the gram light casing 32 may be dropped into a waste bin next to the closet bowl.
  • the textile diaper will need to be washed only if it, itself, has been exposed to the faeces.
  • the cover layers 26 of Fig. 2 could be entirely avoided.
  • This embodiment will or may present the advantage that the outer layer 32 is already in fixed engagement with the inner pad member, such that in general there will be no separated transfer areas in which liquid from the outside can pearl on the wrapping 28 without being sucked into the pad member.
  • the invention is of course not directly limited to the diaper body being washable; even if disposable diaper bodies are used, it will still be advanta ⁇ geous that the pad elements loosely mounted between the crutch barrier strips may be taken out for flushing in a sim ⁇ ple manner, while the remaining diaper is transferred to the solid waste.
  • the permeable skin contact fabric 28 may be entirely disconnected from the diaper body 2, when it is only separable therefrom; by way of example, it may be secured to the diaper body by a burr tape connection.

Abstract

Les couches jetables actuellement largement répandues présentent l'inconvénient de coûter cher et de créer des problèmes d'élimination des ordures alors que l'on connaît déjà l'utilisation de couches textiles lavables en association avec des tampons absorbants constitués de garnitures pouvant être évacuées par les WC. Il convient toutefois de conserver une caractéristique intéressante des couches jetables, notamment la couverture du tampon absorbant par un tissu non absorbant mais perméable au liquide qui donne au toucher l'impression que la couche reste 'sèche'. Dans le cas des couches lavables, ce tissu est monté sur le corps textile de façon fixe, ce qui fait qu'il faut le laver après chaque utilisation. Selon l'invention, ce tissu est utilisé comme pièce séparée, soit comme accessoire de couche de haute qualité réutilisable, soit comme enveloppe des tampons proprement dits, auquel cas, il n'est pas nécessaire de laver le corps textile après des incidents mineurs dans la couche. Le tissu perméable peut se laver et sécher séparément avec une consommation réduite d'énergie. Par ailleurs, les tampons de garniture peuvent rendre le lavage superflu dans la mesure où ils sont jetables, que ce soit par évacuation ou par mise en décharge sous forme de déchet rigide après rinçage du matériau absorbant.
