The present invention relates to a method and apparatus for washing a nappy (or diaper), particularly a nappy having a tongue portion for collecting excreta from a baby.
It is widely believed that re-useable nappies are considerably better for the environment than disposable nappies. In particular, disposable nappies occupy a significant volume in land-fill sites and may also contain various complex chemicals, the production or disposal of which may have harmful effects on the environment. It is therefore desirable that more people use re-useable nappies. However, many people are reluctant to do so because this type of nappy is perceived as being onerous and/or unpleasant to clean, as well as being considered by some to represent a hygiene risk when washed with other clothing.
Various solutions to washing nappies have been considered. One such solution is described in U.S. Pat. No. 3,380,971, which shows a device for cleaning a soiled nappy (referred to as a diaper in the USA). The device includes a net attached to a toilet bowl so that a soiled nappy may be placed in the net and cleaned in the water of the toilet bowl when the toilet is flushed. However this arrangement is not considered to be especially effective; for example, much of the excreta would appear to simply be deposited onto other parts of the nappy during flushing and not properly removed from the nappy.
The present invention seeks to provide an improved solution for washing nappies, and seeks to mitigate or remove at least some of the above-mentioned problems.
According to a first aspect of the invention, there is provided a toilet having a nappy holder mounted thereon, the toilet comprising a toilet bowl and the nappy holder containing a nappy comprising a main body portion and a tongue portion connected thereto for collecting excreta from a baby, wherein the tongue portion of the nappy is positioned away from the main body portion of the nappy, such that when the toilet is flushed, the flush washes over the tongue portion and washes excreta off the tongue portion and into the toilet bowl. The above-described arrangement therefore allows a relatively simple, yet hygienic and effective, method of washing the nappy. In particular, the arrangement enables what is generally the most heavily soiled part of the nappy, the tongue portion, to be subjected to the vigorous flush action of the toilet, thereby mitigating the need for the person cleaning the nappy to become too involved with any unpleasant handling of the nappy.
It will be appreciated that the above-mentioned arrangement does not necessarily seek to provide a replacement for washing the nappy elsewhere (for example in a high-temperature wash in a washing machine) but instead seeks to enable removal of a significant portion of the excreta such that the nappy may be more easily, pleasantly and/or hygienically handled by the cleaner.
The nappy holder may be arranged such that the tongue portion of the nappy is positioned away from the main body portion of the nappy, such that when the toilet is flushed, the flush washes over the tongue portion and washes excreta off the tongue portion and into the toilet bowl.
The nappy comprises a main body portion and a tongue portion connected thereto for collecting excreta from a baby. Such a type of nappy will be readily identifiable by a person skilled in the art. The main body portion typically comprises towelling arranged to wrap around the crotch of the baby and includes two pairs of connectors (one pair at the rear of the nappy and one pair at the front of the nappy), the opposing pairs of connectors being joinable at the hip of the baby to define two openings for the baby's legs. When the nappy is being worn, the tongue portion is typically folded up and located in the undercarriage of the nappy so as to collect excreta from the baby. It will be appreciated that the tongue and main body portions may be a number of shapes and sizes not specifically described herein. The nappy is preferably reuseable.
At least part of the tongue portion may be located outside the nappy holder. The tongue portion of the nappy may be primarily positioned outside of the nappy holder. For example, the tongue portion may be arranged to hang outside the nappy holder whilst the main body portion of the nappy is retained in the nappy holder. In such arrangements there may, of course, be a region of the tongue that is still located inside the nappy holder. Alternatively, the tongue portion may be entirely located outside of the nappy holder.
At least part of the tongue portion of the nappy may be located between the nappy holder and the toilet bowl. The tongue portion of the nappy is preferably primarily located between the nappy holder and the toilet bowl. Such an arrangement is thought to be particularly effective in avoiding contamination of the main body portion of the nappy, when excreta from the tongue portion are washed off by the flush.
At least part of the tongue portion of the nappy may directly rest against the toilet bowl. Such an arrangement seeks to ensure that the tongue portion is positioned such that a significant portion of the flush water runs over the tongue.
The nappy is preferably arranged such that the flush washes over the tongue portion and washes excreta off the tongue portion and into the toilet bowl, but does not wash over the main body portion.
Many toilets are arranged such that the main source of the flush is at the front or rear of the toilet bowl. The tongue portion is preferably arranged in the region of the toilet bowl at which the flush is strongest. The tongue portion may be arranged at the rear of the toilet bowl. The tongue portion may be arranged at the front of the toilet bowl. The tongue portion preferably extends in a direction substantially parallel to the direction of the flush.
The nappy holder is preferably arranged to allow the passage of water through the nappy holder. The nappy holder may be defined, at least in part, by a perforated structure, such that the main body of the nappy may be retained in the nappy holder whilst allowing passage of water through the nappy holder. The perforated structure may take a number of forms. For example, the perforated structure may comprise flexible webbing.
The nappy holder may be defined, at least in part, by a wire frame, the frame being arranged such that the main body of the nappy may be retained in the nappy holder whilst allowing passage of water through the nappy holder. The wire frame comprises plastic-coated wire, for example, plastic-coated steel wire. The wire frame has been found to provide good structural support to the nappy holder whilst still allowing passage of water through the nappy holder. The wire frame may comprise a series of generally circular hoops, connected by interconnecting arms.
The nappy holder may comprise a lip, the main body of the nappy being held in the nappy holder but the tongue portion of the nappy passing over the lip to lie outside the nappy holder. The lip may be located on, for example, a slot in the side of the nappy holder. The nappy holder may be generally open on at least one side, an edge of the nappy holder on that side defining the lip. In an embodiment of the invention in which the nappy holder comprises a series of generally circular hoops, the lip may be defined by part of one of the hoops.
The nappy holder preferably comprises a generally bowl-shaped region for holding the main body portion of the nappy. The nappy holder is preferably arranged such that the region for holding the main body portion of the nappy is located in the toilet bowl. The region for holding the main body portion of the nappy is preferably above the water level in the base of the toilet bowl. The tongue portion of the nappy is preferably located above the water level in the base of the toilet bowl.
The overall shape of the nappy holder may be generally bowl-shaped, the base of the bowl being arranged to hold the nappy and the rim of the bowl being arranged to mount on the rim of the toilet bowl.
The nappy holder may be mounted on the toilet in a number of different ways, but is preferably arranged to rest on the rim of the toilet bowl.
According to another aspect of the invention, there is provided a nappy holder for use as the nappy holder in any other aspect of the invention, the nappy holder being mountable on a toilet and being arranged to hold a nappy comprising a main body portion and a tongue portion connected thereto for collecting excreta from a baby, the nappy holder being arranged such that during use, the tongue portion of the nappy may be positioned away from the main body portion of the nappy, such that when the toilet is flushed, the flush washes over the tongue portion and washes excreta off the tongue portion and into the toilet bowl.
According to yet another aspect of the invention, there is provided a method of washing a nappy comprising a main body portion and a tongue portion connected thereto for collecting excreta from a baby, the method comprising the steps of:
(i) providing a nappy holder;
(ii) placing the main body of the nappy in the nappy holder;
(iii) mounting the nappy holder on a toilet; and
(iv) flushing the toilet, wherein steps (i) to (iii) are such that the tongue portion of the nappy is positioned away from the main body portion of the nappy and such that when the toilet is flushed, the flush washes over the tongue portion of the nappy and washes excreta off the tongue portion and into the toilet bowl.
It will be appreciated that steps (i) to (iii), and particularly steps (ii) and (iii) may be performed in any order. For example, the nappy may be placed in the nappy holder and the nappy holder may then be mounted on the toilet, or the nappy holder may be mounted on the toilet and the nappy may then be placed in the nappy holder.
Any features described with reference to one aspect of the invention may be equally applicable to another aspect of the present invention. For example, the nappy holder according to one aspect of the present invention may incorporate any of the features of the nappy holder described with reference to the method of the invention and/or the toilet according to another aspect of the invention, and vice-versa.

Nappy holder 15 includes a wire frame formed by three co-axial wire hoops 21a-21c, connected by interconnecting arms 23a-23d. The wire forming arms 23a-23d and hoops 21a-21c is plastic-coated steel wire. Nappy holder 15 is generally bowl-shaped with a lower region 27 for holding the main body of a nappy (e.g., main body portion 3 of nappy 1), and a flared upper region 29 for resting on the rim of toilet bowl 17. Lower region 27 of nappy holder 15 is positioned just above the water in the bottom of toilet bowl 17. Arms 23a-23d and hoops 21a-21c in the frame have a relatively close spacing in lower region 27 of nappy holder 15 so as to provide support for nappy 1 whilst allowing passage of water through nappy holder 15. Outermost wire hoop 21a in upper region 29 is of a size that approximately corresponds to the diameter of toilet bowl 17. Upper region 19 of nappy holder 15 is flared such that it rests in a stable configuration on rim 19 of toilet bowl 17.
A nappy may be placed in the nappy holder in order to wash the nappy, as is described in detail below.
