Definitions

• the present invention generally relates to a receptacle for storing a material and more specifically to a receptacle having an inner and outer container wherein the material is contained within the inner container and the outer container prevents spillage in the event of the inner container being damaged.
• waste oil such as waste edible oil or fat which causes pollution.
• Waste edible oil or fat is the dirty oil or fat obtained from deep or shallow fat fryers and when grilling, frying or roasting meat.
• the waste edible oil or fat can be in liguid, semi- liquid or solid form.
• waste edible oil or fat is a problem.
• Some catering premises disguise their waste oil or fat (so as to reduce refuse costs) and the waste oil or fat is thus collected by local authorities and mixed with other refuse. This refuse is then generally emptied into landfill sites and rain eventually washes the oil or fat into rivers and streams, thus causing pollution.
• the waste edible oil or fat is poured directly into the drainage system by catering and domestic users. This oil causes pollution and can solidify and eventually cause blockage.
• waste edible oil or fat does break down in water it uses up vast amounts of oxygen in the process, hence removing oxygen that would otherwise have remained in the waterways for wildlife. Thus due to the way waste edible oil or fat spreads, even a small quantity can cause a great deal of harm. It will be appreciated that similar problems may apply to the storage of other substances whose storage needs to be controlled, e.g. because of legislation, particularly controlled waste.
• the object of the present invention is to provide a receptacle for storing material which can receive and contain the material safely.
• a further object of the present invention is to provide a receptacle for oil or fat which can be provided for small scale domestic use and allow for the easy emptying of the oil or fat from the receptacle.

• the shape of the outer container 1 can be chosen to be aesthetically pleasing and such a receptacle can be provided in public places such as amenity sites, car parks, shopping precincts, supermarkets and schools. The public will be encouraged to bring their waste oil or fat to be recycled.
• the receptacle of this embodiment of the present invention provides for an environmentally safe recycling system since, if the inner container 2 were to leak, the oil would be contained within the outer container 1.
• the volume of the space between the inner and outer containers is 110% of the volume of the inner container.
• the oil or fat can be removed from the inner container 2 either by syphoning or sucking the oil or fat out or by removing the inner container 2 from within the outer container 1. Once the inner container 2 has been removed this can either be emptied into a container on a lorry or the inner container 2 can be replaced.
• the heater 8 can facilitate the emptying of the oil or fat within the container 2 since raising the temperature of the oil or fat will reduce its viscosity.
• the inner container 2 can be provided with a handle (not shown) .
• the electrical connections to the heater within the inner container can either comprise pins and sockets in the bases of the inner and outer containers 1 and 2, or electrical wires can be provided from positions on the side of the inner and outer containers 1 and 2 which are disconnectable as the inner container 2 is extracted from the outer container 1.

• the inner container 13 is also provided with a handle 15 attached to the upper end to allow the removal of the inner container 13 from within the outer container 11.
• the lid 12 of the outer container 11 has an aperture 16 in the side thereof which communicates with a chute 17 to allow the waste oil or fat to be poured through the aperture 16 down the chute 17 and into the inner container 13.
• the aperture 16 in the lid 12 is provided with a lockable stopper 18 to seal the aperture 16.
• the lockable stopper 18 may be a screw cap or may be a lockable self-closing flap with appropriate seals.
• a dipstick 19 which extends from a lock spring 20 into the inner container 13. By releasing the lock spring 20 the dipstick 19 can be retracted from the inner container 13 and out of the lid 12 to allow the determination of the level of the waste oil or fat within the inner container 13 without having to remove the lid 12.
• the outer container 11 is designed to be of an aesthetically pleasing shape and the lid 12 is attached to the outer container 11 by locks 21 on either side.
• both the outer container and the lid 12 may be provided with protrusions which co-operate with indentations in a lockable metal band to lock the lid to the outer container.
• the inner container 13 can be withdrawn through the open upper part of the outer container 11 to allow the removal of the waste oil or fat therefrom.
• the oil or fat can be removed by syphoning or by suction using a vacuum pump.
• the outer container 11 is arranged to be lockable to a base 22 which itself can be secured to the floor or ground e.g. using bolts. This provides for a secure fixing arrangement to prevent removal of the receptacle.
• Figures 1 and 2 provide alternative arrangements for a Waste Oil Bank to which commercial or domestic users can bring waste oil or fat.
• a receptacle comprising an outer container 30 which is of an aesthetically pleasing shape and which has a handle 31 and a removable lid 32.
• an inner container 33 for containing the waste oil or fat.
• the inner container 33 comprises a cylinder which is closed at a lower end thereof and open at an upper end thereof.
• a piston 34 which is of disc shape.
• a pivot arm 35 On an upper face of the piston 34 there is provided a pivot arm 35 having a pivot 36.
• a link rod 36a which is pivotably attached to the piston 34 by the pivot 36.
• the link 36a extends the length of the inner container 33 and is pivotably attached to a handle 37 at the other end thereof.
• the handle 37 comprises an elongate member extending across the circumference of the open end of the inner container 33.
• the handle 37 is pivotably attached to one side of the open end of the inner container 33 by a pivot 38.
• the pivot 40 provides the pivotal connection between the handle 37 and the link rod 36.
• the receptacle provides a safe container for waste oil or fat since if the inner container 33 leaks the oil or fat is contained within the outer container 30.
• Waste oil or fat can be poured into the inner container 33 by removal of the lid 32 from the outer container 30.
• the waste oil or fat can be emptied from the inner container 33 once the lid 32 is removed. If the waste oil or fat is of low viscosity, it can simply be poured out. If on the other hand the viscosity is high, the removal of the waste oil or fat from within the inner container 33 can be facilitated by the action of the piston 34 travelling the length of the inner container 33 from the closed end to the open end of the inner container 33.
• Figure 3 shows the piston residing at the closed end of the inner container 33 which is the position it will assume during the filling of the inner container 33.
• Figure 4 illustrates the piston once it has reached the open end of the inner container 33.
• the piston 34 is moveable by the lifting of the handle 37 such that it pivots about the pivot 38.
• the lifting of the handle 37 causes the link rod 36 to urge the piston 34 upwards.
• the link rod 36 contacts the protrusion 41 on the lower face of the handle 37 thus preventing further motion of the handle 37, link rod 36 and piston 34. This prevents the withdrawal of the piston from within the container 33.
• the piston 34 is thus able to extract waste oil or fat from within the inner container even if the viscosity of the waste oil or fat is quite high.
• the handle can be used to extract the waste oil or fat as the receptacle is tipped.
• the piston 34 extracts the waste oil or fat it can be poured out of the inner container 33.
• FIG. 5 illustrates an alternative arrangement for domestic or small catering use.
• the receptacle comprises an outer container 50 having a handle 51 and an open end 52. Within the outer container 50 there is provided an inner container 53.
• the inner container is provided at a lower end thereof with a piston 54 which seals with the walls of the inner container 53.
• the piston 54 is connected by a piston rod 55 to a base plate 56 on which the receptacle stands.
• the inner container 53 is also provided with a cap 57 which is removable. The cap 57 can be removed by unscrewing it and to aid this action there are provided indents 58 for fingers.
• the base plate 56 in order to lock the outer container 50 to contain the inner container 53.
• the outer container 50 can be removed to expose the inner container 53 by rotating the base plate 56 to disengage the base plate 56 from the locking flange 59 of the outer container 50.
• the outer container 50 can then be lifted by its handle 51 from covering the inner container 53.
• the cap 57 In order then to pour waste oil or fat into the inner container 53, the cap 57 must be unscrewed.
• a piston arrangement may be attached to the lid arrangement of a receptacle according to the first aspect of the present invention.
• the inner container of the receptacle for domestic use may therefore be simplified.
• Figure 7 shows a side view of a flap 60 for use in a lid arrangement for a waste oil bank.
• a link arm 62 Attached to the flap 60 by a pivotal connection 61 is a link arm 62 which is itself attached to a disc-shaped piston 63 by another pivotal connection 64.
• the disc ⁇ shaped piston 63 is sized for a suitable portable container (not shown) such as may be supplied with a receptacle for domestic use.
• the portable container includes an open end and a removable closed end.
• the piston 63 is caused to travel the length of the portable container to remove any semi-solid waste oil contained in the container.
• the inner container of the waste oil bank includes an opening with a chute onto which the portable container may be placed during use of the piston to empty the contents of the portable container into the inner container.
