TITLE
Disposable Waste Bag DFSCRIP1 iON
Field of Invention
The present invention relates to waterless and portable toilets. The present invention provides an improved disposable waste bag for use with a waterless toilet. A waterless toilet system using the improved disposable waste bag is also prcivided Tlhe waterlLss toilet system may be portable.
gkrpund Conventional flushing toilets are relatively wasteful, requiring several litres of water to he used at each flush. In order to reduce this waste of water there is a desire to provide toilets which either minimise water use or are entirely waterless.
It is also necessary for conventional flushing toilets to be permanently connected to both a water supply and a functioning sewerage system. Many, many locations worldwide do not have both a water supply and a sewerage system suitable for flushing toiluts Furthermore, the need for a flushing toilct to be permanently connected to a water supply and sevveragc system means that flushing toilets have to be fixed in position and cannot be portable. In light of this, there is a desire to provide toilets that do not require a connection to a water supply or a sewerage system and
that are portable.
Many such toilets hase bccn proposed TI ypically, the toilets are portable and substantially comprise a platform that can either be mounted on a stand that elevates the platfonn above a surfce orincludes means for supporting the platform above the surface. The platform has a central aperture and acts as a toilet seat, The portable toilet will also comprise a receptacle for receiving waste matter that may be positioned below the aperture of the platform when the toilet is in use. After use the receptacle is either emptied and re-used or is discarded A known embodiment of a portable toilet is waterless and comprises a receptacle that is substantially a plastic waste hag and the platfonn additionally comprises clamping means around the edge of the aperture for supporting the waste bag therefrem. The clamping means comprises a um about ihich the upper edgc of a waste big may be located and a cooperatnicly formed hinged upper member which may be lowered into position around the rim in order to clamp the upper edge of a waste bag thci cbetween FUe hinged upper member has the sanic appearance as a conventional toilet seat The rim is formed around the edge of the aperture formed through thc platform and the upper member has a coopcrativclv positioiicd apcrtae formed therethrough in the same mannei as a conventional toilet stat In this portable toilet, after a Waste bag has been used the hinged upper member is lifted to unclamp the waste bag. The waste bag is then lifted out of position and disposed of Ti h1s process can he unpleasant and unsanitary as it is necessary to support the waste bag as it is unciamped from the platform This can involve a person placing their hands inside the waste bag in places where the bag may have been in contact with waste matter. Furthermore, after the waste bag has been unclatnpcd it is necessary to manually seal the bag using am scaling means that may be piesent along the open portion of the wa5te bag.
In light of the above, there is a need for an improved waste receptacle for use waterless toilet system wherein the Waste receptacle is sanitary and less unpleasant to ttnload after use, There is also a need for a waterless toilet system for use with an inrpro ed waste receptacle that is capable of use either as a replacement for a conventional toilet or in locations whue there is no access to a water supply or 4 sewerage system It is also preferable that any such toilet system should be portable
Summary of Invention
The present invention provides a disposable waste bag for use with a waterless toilet S\ stem that conipuses a clamping platfonn for supporting thc wasic bag wheiem the waste hag comprises an inner portion and an outer portion; -j the outer portion of the hag surrounds the inner portion, has a draw-string and has a shape that allows it to be securely supported by the clamping platform of the waterless toilet system in such a.maicr that the inner portion of the bag extends completely across an aperture o1f the clamping platform; and S the inner portion of the bag eompnses an upper laser and a lower layer, an outer edge of the upper layer being joined to an inner edge of the outtr portion by a line ot sepatation, an outer edge of the lower layer being contiguous with an innei edge of the outer portion and the lower layer being expandable to form a receptacle for waste matter.
The disposable waste bag of the present invention th used with a waterless toilet in the following maimer A clamping means of the clamping platform of th waterless toilet is opened and the disposable waste bag is placed in position in the clamping platform such that the outer portion of the waste bag is in a position to be clamped by the clamping means, the inner portion of the waste bag extends across the aperture of the clamping platform and the upper layer of the inner portion is on the top side of the waste hag. The clamping means is then closed so as to clamp the waste bag in position. A user then presses on the upper layer of the inner portion of the waste bag so as to separate the uppei layer of the inner portion from the outer portion along the line of separation Separating the uppei layer of the inner portion from the outer portion also seres to expand the lower layer of the waste bag such that it forms a receptacle for waste matter J he user is then flee to use the waterless toilet in a conventional manner.
Tn order to allow the lower layer of the inner portion of the waste bag to expand it may initiall be folded such that piessing on the lower layer opens the folds and expands the layer Alteinatively the lower layer of the waste bag may be formed of an expandable materiaL The positioning of the waste bag according to the present invention in a waterless toilet is much easici and simpler than positioning a waste bag according to the prior ait This is because it is not necessary to locate an opening of the waste bag around d rim of the clamping platform. This process can he fiddly as the whole of the opening of the waste hag must be careflully located ensuring there are no gaps. In contrast, the waste bag of the present ins ention can simph be placed in the appropn ate position on the clamping platform and the clamping platform can then be closed.
After a user has used the waterless toilet they may then dispose of the waste bag.
I irst, the waste bag is unclamped from the clamping platform in the conventional manner The user then picks up the waste bag by means of the draw string Doing this doses the waste bag above the waste receptacle formed by the lower k'er of the mnei portion. The user may then seal the bag in a suitable manner and then dispose of the bag. Picking tip the waste bag by the draw string ensures the user does not risk coming into contact with waste matter present in the waste bag. Furthermore, the piLking up the waste bag by the thaw string acts to close the v aste bag under the action of its own weight.
As will be readily appreciated, removal of the waste bag of the present invention is much easier and more sanitary than removing a waste bag according to the prior art.
in particular, the waste bag can be simply picked up by the draw string without the need to reach into the waste bag or the need to manually gather the top of the hag with the associated risks of coming into contact or spilling waste mattei located within the bag.
Preferably a waste bag according to the present invention will contain an absorbent.
That is, the waste reccptacle portion of the waste bag may contain a material tor absorbing waste matter deposited therein The absorbent inateual may include a gelhng agent tor solidifying liquid wastc author an odour neutrahsing agent The absorbent may be in the form of an absorbent lining. As will be readily understood, if the bag has an absorbent lining this lining may be attached to the lower layer of the inner portion of the hag in a suitable position. Additionally or alternatively, the absorbent may he present in the form of loose material within the hag.
When a waste bag according to the present invention is used the lower wall of the inner portion is extended to form a waste receptacle. In order to ensure that any waste deposited in the waste receptacle of the waste hag is securely held and may not leak out it may be preferable that the portion of the lOwer wall that forms the waste receptacle is made of a more resilient material than the rest of the waste bag. For example if the waste bag is formed of a polymer it may be preferable that the televant portion ol the lower wall is formed of a thicker higher grade polymer 1-lowevem it is to be understood that the relevant portion of the lower wall may be formed of a different material from the rest of the waste bag if it is so desired.
Preferably a waste bag according to the present invention will he made of a polymer.
This is because polymers are cheap and easy to manufacture on a large-scale and are readih a' ailable A preferred embodiment of a waste bag according to the present invention is substantially made of polythene.
in a preferred embodiment of the present invention the line of separation joining the upper layer of the inner portion to the outer portion is a perforated tear line. This allows the upper layer of the inner portion to he easily separated from the outer portion by pressing on the upper layer.
in order to provide instructions for use of the bag or to provide space for advertising or an other graphics, a waste bag according to the present invention may have paper layer adhered to at least a portion of an upper surface of the waste bag Preferably any such paper layer will be adhered to a top surface of the upper layer of the inner portion of the waste bag such that when the vate bag is ulqmncd in position in a waterless toilet sy stem the aperture of the clamping platfonn is initially substantialls covered by the paper layer.
The present invention also provides a waterless toilet system comprising a waste bag as described above and a clamping platfonn for supporting the waste bag. wherein the chmntping platform has a central apcrture and compnses clamping means for damping the waste bag across the central aperture. The clamping platform may he a substantially conventional platform according to the prior art.
Preferably, the clamping platfoim comprises a lower part and a hinged upper part between which a waste bag may be clamped and wherein the central aperture is formed through both the lower part and the hinged upper part The htngcd uppei part may be similar to a conventional toilet seat but may have a part of the damping means formed on its lower side A eooperatn ely posifloncd second part of the clamping means may be formed on an upper side of the lower part of the clamping platform The clamping means may comprise a ridge formed around either the lower or uppci part of the damping platform and a cooperatnely tormed channel formed around the other of the lower or upper part of the clamping platform In such an embodiment of the present insention a waste bag may be clamped in the clamping platform b\ lifting the upper pad of the clamping platform placing the waste bag in a suitable position on the lower part of the clamping platform, then closing the upper part of the damping platform such that the ridge becomes engaged with the channel and clamps the waste bag.
