Abstract

A waste container apparatus (1) is described. The waste container apparatus is adapted and constructed to collect non- fluid waste while allowing fluid waste to enter a waste water disposal system. The waste apparatus is of particular use in collectin waste from a kitchen sink.

Description

WASTE CONTAINERAPPARATUS
FIELD OF INVENTION:
This invention relates to a waste container apparatus. The invention is directed particularly but not solely towards a waste container apparatus for household waste.
BACKGROUND OF INVENTION:
Traditionally household waste goes down the drain. This waste can include solid plant matter (for example vegetables), that is ground up by a waste disposal unit or a grinder for example. This must be combined with fluid to enable it to be carried away down the sink drain. The sink drain is normally connected to a reticulated waste or sewer system which includes conduits or pipes.
Alternatively the sink drain can be connected to a septic tank which may or may not allow ground plant matter therein.
At present solid kitchen waste may be disposed of through a waste disposal unit with the waste being directed into a sewer system. Alternatively, waste is collected and physically placed in a rubbish tin for council collection. There appears to be no method of disposal which allows people to retrieve kitchen waste that has been ground up by a waste disposal unit for example and use it elsewhere.
Kitchen waste, if measured according to volume, can easily bulk out the waste volume such that waste pipes and outfalls can be overloaded causing pollution at the outlet. Also kitchen waste can cause blockages in both household pipes and in the reticulated system. Blockages can cause a back-up of fluid in the waste pipes, causing pollution at the household end. The greater the volume of waste entering the waste sewer system, the greater the level of expenditure that is required to maintain the existing pipe capacity and cope with the natural increase in waste due to population growth.
High volumes of waste can also combine with illegal stormwater connections causing an overloading of the reticulated system to cause further pollution. When kitchen waste is dumped in a rubbish bin it further contributes to filling council land-fills, reducing their capacity and necessitating more land-fill areas. In addition, high levels of solid waste can contribute to the biological load of wastewater treatment systems, requiring additional treatment and resulting in an increase in power and operational costs. Further, in high rate wastewater treatment plants additional sludge will result, which is usually disposed of in landfills. Extra stress can also be put on infrastructure such as pipes when high levels of solid waste are present.
Kitchen waste can be a good source of fertilizer for the garden. Common fertilizers are costly to purchase and can be detrimental to the environment through run off and pollution.
OBJECT OF THE INVENTION:
It is therefore an object of the present invention to provide an improved waste container apparatus that at least ameliorates one of the aforementioned problems and/or to provide the public with a useful choice.
STATEMENT OF THE INVENTION:
Accordingly, in a first aspect the invention provides a waste container apparatus, the waste container apparatus being adapted and constructed to collect non-fluid waste while allowing fluid waste to enter a waste water disposal system.
Preferably, the waste container apparatus comprises an outer container and an inner container, an inlet adapted to direct fluid and non-fluid waste from outside the apparatus into the inner container, and an outlet adapted to direct fluid waste away from the apparatus, wherein the inner container includes one or more apertures adapted to in use allow fluid waste to pass therethrough into the outer container while substantially capturing non-fluid waste within the inner container and means to allow removal of the non-fluid waste captured therein.
Preferably, the one or more apertures have dimensions of greater than or equal to substantially lmm by lmm. More preferably, the apertures are substantially 1.5mm wide by substantially 2 to 10 mm long, even more preferably substantially 1.5mm wide by up to substantially 90mm long.

DESCRIPTION OF THE INVENTION: The invention relates to a waste container apparatus adapted to collect non-fluid (for example solid food scraps) waste present in a waste outlet, while allowing fluid (for example water or other liquid) waste to pass through the apparatus into a standard waste conduit. In particular the apparatus is adapted for use in collecting waste from a kitchen sink, particularly organic waste such as food scraps, which would be otherwise directed through a plumbing systen into a centralised waste water disposal and/or treatment system. The solid waste can be emptied from the apparatus and disposed of or recycled as appropriate.
The waste container apparatus is described herein after in terms of use in a domestic kitchen. However, it should be appreciated that it may find use in commercial or industrial kitchens, factories involved in food preparation and manufacture, and the like; for example, restuarants, cafes, factories, school cafeterias, staff lunch rooms. It may also find application in other environments. As used herein, a "waste water disposal and/or treatment system" should be taken broadly. It is intended to include any retictulated or non-reticulated sewer, septic tanks for example. For ease of reference, the invention may be described herein after refering to only one of these examples. However, this should not be construed to limit the scope of the invention.
The waste container apparatus has a number of advantages including reducing if not eliminating solid waste entering a sewer. It is very effective in conjunction with waste disposal units (for example, an In Sink Erator™ garbarge disposal unit), it provides an effective source of composting material, it reduces the likelihood of blockages due to solid material in waste outlets, it can help reduce pollution for outflows etc and, it can help reduce waste water costs where rates are levied on volume of waste. In addition, it has minimal running costs, it may be readily installed into new and existing waste conduits, it will have a modest manufacturing and purchasing cost, it can be constructed in a convenient size enabling easy handling and removal of waste, it is of robust construction, it is hygienic, it has a substantially odourless operation, it is weather and vermin proof, it has easily accessible componentry, and it includes an openable inner container. Further, the apparatus is adapted to collect non-fluid waste in a single location within an inner container which may be readily removed from the apparatus by hand to empty it of its contents. The apparatus does not require expensive equipment to empty it of its contents. When used in conjunction with a waste disposal unit the apparatus allows for collection of food waste which can be broken down by compositing in the space of approximately 2-3 weeks, as opposed to a standard period of approximately 3 months where unprocessed food scraps are composted.
In the description and figures which follow, common reference numerals are used to designate like features in the different embodiments of the invention.
As shown in figures 1 to 15 there is a waste container apparatus generally referenced by arrow 1 having a container portion generally referenced by arrow 2 having an inlet 3 and an outlet 4. The inlet 3 and outlet 4 may simply comprise apertures in the relevant components of the apparatus. Alternatively they may comprise tubes which are integral to the apparatus.
In either case, the inlet 3 and outlet 4 are adapted to connect in use to standard waste, plumbing or other suitable conduits, or directly to a kitchen sink outlet or waste disposal unit. By way of example, inlet 3 is connectable to a standard waste outlet from a kitchen sink or to a waste disposal unit and the outlet 4 is connectable to a waste conduit adapted to direct the waste away from the apparatus toward a sewer. The container portion 2 comprises at least one inner container 5 and one outer container 6.
Outer container 6 forms an inner volume 7 and inner container 5 forms an inner volume 8. Container 5 is adapted to allow waste to enter there into and has at least one aperture 11 to allow at least fluid to exit therefrom while causing any non fluid waste to be captured in the container 5.
Outer container 6 is most preferably adapted to open to allow access to the inner container 5. The inner container 5 is adapted to open or otherwise allow for non-fluid waste contained therein to be removed following waste collection. Preferably, the apparatus is constructed to allow opening of the apparatus and removal of the waste by hand.
The inner and outer containers can be fabricated from any suitable materials including plastics or non plastics such as metal. Combinations of one or more different materials may be used to fabricate the apparatus. Containers 5 and 6 can be constructed of clear or translucent material (for example PVC, polycarbonate or any other plastics material (2mm thick for example)) so that inner volume 7 of the outer container and/or the inner volume 8 of the inner container, including any waste present therein, are visible in use.
The apparatus may contain means to cope with overflow, or means for preventing further waste entering the apparatus or to allow for a waste disposal unit attached to the apparatus to be disabled as the level of waste in the apparatus nears or reaches a maximum capacity. By way of example, overflow pipes and outlets may be present, or the apparatus may include a float switch or the like, including a float plate (such as a vertical float plate) or a pivot arm for example, which in use can activate the switch to disable a waste disposal unit when the apparatus nears or reaches a maximum capacity. Specific examples are provided herein after.
The apertures 11 of the inner container 5 may be of any size suitable to allow non-fluid waste which may enter the apparatus from a standard waste outlet (such as a kitchen sink) to be captured within the inner container while allowing fluid waste to pass therethrough. Preferably, the apertures are of a size suitable to catch non-fluid waste which has been processed through a waste disposal unit, while allowing fluid to pass therethrough. Preferably, the one or more appertures have dimensions of greater than or equal to substantially lmm by lmm or have a diameter of greater than or equal to substantially lmm. More preferably, the apertures are substantially 1.5mm wide by substantially 2 to 10 mm long, and even more preferably substantially 1.5mm wide by up to substantially 90mm long.
The outlets of the apparatus (for example, outlet 4 and overflow outlet 17 as shown in Figure 5, for example)) may be fitted with mesh or other suitable filter material (for example plastics materials including apertures therein), so as to help minimise or prevent residual non-fluid waste exiting the apparatus and entering the sewer system. Similarly, the inner container 5 may be lined with mesh or other suitable filter material to cover apertures 11 so as to minimise or prevent very fine non-fluid waste entering the sewer system. Preferably, the mesh or other suitable filter includes apertures of greater than or equal to substantially lmm by lmm. More preferably, the filter includes apertures which are substantially 1.5mm wide by substantially 2 to 10 mm long.
The apparatus can be designed to have any suitable capacity. By way of example, the inner container can have a capacity of 20 litres. Depending on the volumes used, the shape, size and numbers of these containers and their outlets/inlets can be varied accordingly. Further means of fixing the unit to a wall, piping or fixing the lid etc are also envisaged.
In use the inlet 3 is connected to the outlet of a standard kitchen sink outlet. Various methods of connecting are possible such as flexible hose or mating parts. Various configurations of standard plumbing conduits can connect to the apparatus. Piping which includes s-bends is of particular use as it can help prevent odours escaping from the apparatus or piping connecting thereto. Connecting to the kitchen waste can mean that the waste container apparatus assembly can be located conveniently outside of the house immediately adjacent the waste outlet from the sink or alternatively inside the house in a cupboard. The outlet 4 for the container can be re-connected directed to a gully trap or other waste conduit or sewer system.
In use waste enters the waste container apparatus 1 at inlet 3 and enters the inner volume 8 of the inner container 5. The waste will normally consist of non-fluid and fluid matter. Fluid can exit or drain/seep from the inner volume 8, via apertures 11. The volume of non fluid waste in the inner volume 8 builds up with seepage of the fluid occurring through apertures 11. As the level of fluid and non fluid waste rises any overflow can exit through an overflow means (for example, the pipe 12 illustrated in Figures 1 and 2), or it can enable activation of a switch to disable a waste disposal unit attached to the apparatus thereby preventing further waste from entering the apparatus.
Emodiment 1
One embodiment of the invention is illustrated in Figures 1 to 3. In this embodiment, the waste container apparatus is in a substantially vertical configuration including outer container 6, inner container 5, inlet 3, outlet 4, and a plurality of apertures 11 to allow fluid to exit the inner container 5.
Outer container 6 has a base portion 14, a top 15 and a removable lid 16. Lid 16 is adapted to sealingly fit to the container 6 such that odours escaping from the outer container 6 are eliminated or significantly reduced. The lid also can eliminate weather and vermin entry.
Container 5 has an overflow outlet 12 which comprises an elongate hollow member being adapted to facilitate flow therethrough. The overflow outlet 12 has an inlet aperture 33 and outlet aperture 34. The inlet aperture 33 is, in use, approximately level with the top 10 of the inner container 5. As illustrated in Figure 2, inner container 5 can have a lid 13, including an inlet aperture 27. In use any overflow from the inner volume 8 enters the top end (through aperture 33) and can exit out of the inner container through the outlet aperture 34 at the lower portion of the tube 12 and into the outer container inner volume 7 to further exit through outlet 4. The lower and upper portion of overflow outlet 12 can be angled or apertured to further allow the efficient entry of overflow from the inner container and exit of overflow into the outer container. The lower portion of overflow outlet 12, in use rests and/or is supported by the inner surface of base 14 of outer container 6. This support combines with the fixing of the inlet and outlet to stabilize the the position of the inner container 5 relative to the outer container 6. Further support parts may be included to further support the positioning of the inner and outer containers.
In addition, the base 14 of the outer container may be angled or slope down toward outlet 4 to further promote efficient exit of fluid waste from the apparatus.
Inlet 3, and outlet 4 can also have a structure or shape to eliminate or reduce odours such as an s-bend or venting, as may be appropriate. The waste container apparatus of this embodiment of the invention will operate in use as hereinbefore generally described. As the level of fluid and non fluid rises within the apparatus any overflow can exit through the overflow pipe 12.
If the waste container apparatus is left to fill up or the user forgets to empty or replace the inner container, the overflow which can be sized to match existing waste pipe diameters, can function automatically to divert flow straight to the waste outlet thereby mirroring an existing outlet waste system.
Preferably, the inner and outer containers are transparent or at least translucent so that the user can check the level of waste present in the apparatus and empty before it reaches full capacity and the overflow comes into operation.
An optional lid 13 may be placed on the inner container 5 allowing for the storage of this container if it is not convenient to empty it at the time it is removed from the apparatus. One or more replacement inner containers may be provided to help ensure a container is free for use while other containers are being washed, or used to transfer waste for disposal or composting, for example.
Embodiment 2
Figures 4 to 8 illustrate another embodiment of the invention. In this embodiment the waste container apparatus is in a substantially horizontal configuration, with the same reference numerals indicating similar components and features as for the apparatus of the first embodiment (figures 1 to 3).
In this embodiment, the outlet 4 is positioned in an end of the outer container 6, as opposed to the base 14 of the outer container as in the first embodiment (Figures 1 to 3). This positioning may help prevent or minimise the potential for blocking of the outlet, caused by any residual non-fluids which may have entered into the outer container, when the outlet includes a filter. The outlet 4 preferably is located in close proximity to the base 14 of the outer container 6. In addition, the apparatus of this embodiment includes an upper overflow drain or outlet 17 positioned above the outlet 4 of the outer container 6, and preferably in close proximity to the top 15 of the outer container 6. In a preferred form of this embodiment, filters 20 are present at one or both of the outlet 4 and overflow outlet 17, in order to help prevent any residual non-fluid waste exiting the apparatus. The base 14 of the outer container may be angled or slope down toward outlet 4 to promote efficient exit of fluid waste from the apparatus.
The outer container 6 has an opening lid 16 at the end of the outer container opposing the end in which the outlet 4 and overflow outlet 17 are positioned. The lid 16, can include a handle.
The inner container 5 includes two halves connected by a hinge 18, which can be for example a living hinge, though any other hinge able to provide opening and access to the inner container is also possible. The inner container 5 also has a handle 19 to enable easy removal from the outer container for cleaning and/or to inspect the level of waste, for example. Further, it includes a releasable fastening means 21 which allows the two halves of the inner container to be secured in a closed position while in use. A plurality of apertures 11 are provided in both halves of the inner container as well as an inlet aperture 27 to which the inlet 3 of the outer container 6 aligns or registers.
A preferred feature of this embodiment of the invention is a float plate 22 which floats or moves in an upward direction when the inner container is full to activate a switch 23 which disables a waste disposal unit when attached to the apparatus so that the unit can not be used until the inner container has being emptied (Figures 6 and 7).
Embodiment 3
Another embodiment of the invention is illustrated in figures 9 to 11. In this embodiment the waste container apparatus is in a substantially vertical orientation and the outer container 6 includes inlet 3 and outlet 4 in a substantially horizontal orientation at its base 14, with a wall 26 sealing the inlet 3 from the outlet 4.
The apparatus includes a substantially vertical inlet tube or funnel 25 which in use directs waste from the inlet 3 in an upward direction to enter the inner container 5. The inlet tube 25 may form part of the outer container 6 or the inner container 5, or both (see figures 10 and 11), such that there is a sufficient connection between the inner and outer containers to seal against or at least minimise movement of waste backward into the inlet 3.
The inner container 5 contains a plurality of appertures 11 and a lid 13, which also includes a plurality of apertures. The lid 13 also includes a waste deflection umbrella 24 which in use deflects waste in an outward and downward direction from the inlet tube 25 into the inner container 5.
The apparatus of this embodiment preferably includes a vertical float plate 22 which rises in use when the inner container becomes full with waste to activate a float switch 23 which diables a waste diposal unit when one is connected to the apparatus.
Embodiment 4
The waste container apparatus illustrated in figures 12 to 15 represents a most preferred form of the invention.
In this embodiment, the apparatus is in a substantially horizontal configuration. The outer container 6 includes oulet 4 and overflow outlet 17 substantially in the same position as in the second embodiment (Figures 4 to 8). It also includes an inlet 3 and float swtich 23. The base 14 of the outer container 6 is angled or sloped towards the outlet 4 to aid in draining of fluid out of the apparatus. In a preferred form of this embodiment, the outlet 4 and overflow outlet 17 include filters 20 which help prevent any residual non-fluid waste exiting the apparatus.
The inner container 3 is formed in two halves much the same as the inner container of Figures 7 and 8 , including an appropriate hinge 18 and fastening means 21, and preferably a handle 19. A plurality of apertures 11 are provided in the base portion of the inner container 5. However, the apertures may also be present in the top portion or half of the inner container 5. The inner container includes an inlet aperture 27 and a direct fluid waste conduit 28. The direct fluid waste conduit 28 is fitted at its mouth with a filter so that non- fluid waste is prevented from moving into the waste conduit 28. The filter is preferably fitted in a releasable manner so that it can be removed for ease of cleaning, repair or replacement.
The top edge of the direct fluid waste conduit 28 is angled inward towards the inner volume of the inner container 5. The angle or gradient of the top edge of the conduit 28 may be any suitable to allow waste to be directed into the inner volume of the inner container, having regard to the volume of waste intended for the apparatus, the capacity of the inner container 5 and the like. Figures 13 and 15 illustrate one appropriate gradient, while Figure 14 illustrates another and more preferable gradient. In figure 14 the top edge of the conduit 28 is at an angle of substantially 30 degrees measured from a horizontal line extending from the top end on the conduit and declining toward the inner volume of inner container 5.
While the direct waste conduit 28 illustrated in figures 13 and 14 does not include any apertures 11, the inventors contemplate it doing so. Including apertures on the conduit 28 may allow for improved drainage of any residual fluid present in the volume of non-fluid waste within container 5.
The apparatus also includes a pivot arm 29 including a float which activates a switch 23 when the inner container nears or reaches a maximum capacity, so that a waste disposal unit connected to the apparatus is disabled.
In use, when the two halves of the container are in a closed position, the inlet aperture 27 registers with the inlet 3 of the outer container and is aligned above the direct fluid waste conduit 28 (see Figures 14 and 15). Waste 30 from a kitchen sink or waste disposal unit moves through inlets (inlet 3 and inlet aperture 27) into the inner container 5. Fluid waste 32 may escape the inner container direct through the direct fluid waste conduit 28, while the filter prevents or at least minimises the passage of non-fluid waste 31 into the conduit 28. Ih addition, the angle of the filter directs non-fluid waste 31 away from the mouth of the conduit 28 and into the inner volume 8 of the inner container. Any residual fluid present in the inner volume 8 of the inner container 5 can seep or drain out of the inner container through apertures 11 and into outlet 4.
In one form of this embodiment of the invention mesh or alternative filter material may be used to line regions of the the inner container 5 having apertures 11. This can provide for additional filtering of fluid and non-fluid waste to help prevent fine non-fluid waste escaping the inner container 5.
This invention may broadly be said to consist in the parts, elements and features referred to or indicated in the specification of the application individually or collectively.
Where specific integers or components are mentioned herein have known equivalents, such equivalents are incorporated herein as if individually set forth.
