The present invention relates to a container for waste electrical and electronic equipment (“WEEE”).
There is a need to dispose of WEEE in a safe environmentally friendly manner. There is a European Community Directive on the disposal of WEEE, which covers a wide range of products ranging from large items such as televisions and computers to smaller items such as light bulbs and fluorescent tubes. Luminaires used in commerce, industry, public places and so forth have to be disposed of in accordance with the Directive. Whilst domestic luminaires are not covered by the Regulation, consumers are encouraged to dispose of them in a safe and environmentally friendly manner, and there are safety issues regards toxic materials. Whilst conventional incandescent light bulbs do not raise significant issues as regards toxic materials, fluorescent light tubes contain quantities of toxic materials such as mercury, cadmium and lead. Many low energy light bulbs that are being introduced in order to reduce energy consumption operate on the fluorescent principle and their disposal presents problems.
To prevent breakage of a fluorescent light and release of toxic material, there needs to be a system for packaging them for transport to a safe recycling site. There have been various proposals for achieving this involving packing the lights into a container tightly, so that they cannot move around, with the accompanying risk of breakage. This may be appropriate for large organisations with a large turnover in lights, but it causes problems for smaller organisations where it might take a considerable time for sufficient lights to be accumulated to fill the container. It also presents problems for councils and others who provide recycling points, as there is no guarantee that consumers will pack lights correctly into the container without breakages, or in such a manner that there is a low risk of breakages in subsequent transport of the container.
According to one aspect of the present invention there is a provided a container for the storage and transport of waste electrical and/or electronic equipment having therein at least one horizontally disposed tray provided with an array of upwardly projecting resilient locating portions, adapted to receive a plurality of waste electrical and/or electrical items in a plurality of different orientations in which the items will occupy spaces between the locating portions and will be gripped by the locating portions. The items could be, for example, old mobile telephones or the like, although in general it is intended that the array of projections will be capable of receiving waste electric lights of various types such as fluorescent tubes, light bulbs, spot lights and various forms of lamp.
By way of example, in one embodiment of the invention there may be provided a matrix of spaced locating portions arranged in rows and columns. Preferably the matrix is regular with evenly spaced rows and columns. Considering an elongate, cylindrical fluorescent tube, this could be disposed in a gap extending between adjacent rows, or a gap extending between adjacent columns, or a gap extending diagonally. A mobile telephone could be located in a similar manner. A light bulb could be positioned with its bulbous end in the space between four adjacent locating portions, and the enlarged end of a spot light can be located in the same mariner.
The array may be in accordance with a pattern or random. A pattern may be in the form of a matrix comprising two series of rows arranged at angle. One series of rows may be arranged perpendicularly to the other, so as to constitute columns. For the purpose of this discussion, the term “column” will be used to distinguish one series of rows from another, regardless of whether the angle between the two series is a right angle or another angle. The direction of a column or row need not be parallel to a main dimension of the container or the tray, which typically will be of rectangular form, but may be at an angle aligned for example with a diagonal. The spacing of portions along a row may be regular or may vary according to a pattern or randomly. The spacing of portions along a row may be the same for each row or may vary from row to row, either according to a pattern or randomly. The spacing of portions along a column may be regular or may vary according to a pattern or randomly. The spacing of portions along a column may be the same for each column or may vary from column to column, either according to a pattern or randomly. The spacing between portions along rows may be the same as or different from the spacing of portions along columns. The spacing between adjacent rows may be constant or may vary according to a pattern or randomly. The spacing between adjacent columns may be constant or may vary according to a pattern or randomly. The spacing between adjacent rows may be the same as or different from the spacing between adjacent columns.
In a typical arrangement, there may be at least about 100 projections arranged in a matrix, and there may for example be at least about 150, or at least about 200, or at least about 225 projections, or at least about 250, or at least about 300, or at least about 350, or at least about 400, or at least about 450, or at least about 500, or at least about 550, or at least about 600, or at least about 625, or at least about 650, or at least about 700, or at least about 750, or at least about 800, or at least about 850, or at least about 900, or at least about 950, or at least about 1000. In a matrix, the spacing between adjacent projections in a row or between adjacent projections in a column may be between about 1.0 mm and about 20 mm, or between about 15 mm and about 30 mm, or between about 20 mm and about 35 mm, or between about 25 mm and about 40 mm, or between about 30 mm and about 45 mm, or between about 35 mm and about 50 mm. These spacings may relate to the maximum available space between the peripheries of adjacent projections, or to the spacing between the centres of adjacent projections. The projections may have diameters, i.e. maximum transverse extents of any parts that will engage items, of up to about 5 mm, or up to about 10 mm, or up to about 15 mm, or up to about 20 mm; or up to about 25 mm,
The form of the locating portions may be constant across the array or may vary in accordance with a pattern or randomly. Variations in form may be in respect of the shape and/or dimensions of the locating portions.
Preferably at least some of the locating portions have a circular cross section. The circular cross section may be of constant diameter along the vertical extent of a locating portion, in which case the locating portion will be in the form of a cylinder. The circular cross section may vary in a regular manner along the vertical extent of a locating portion, in which case the locating portion will be in the form of a cone or a truncated cone. The variation may be such that the larger diameter part is adjacent the base of the locating portion, adjacent the tray surface, or adjacent the top of the locating portion, remote from the tray surface. The circular cross section may vary along the vertical extent of a locating portion in a non-regular manner, and may for example provide a base section having a first diameter, a central section with a smaller diameter than the base section, and a top section with a diameter which is greater than that of the central section, and may be the same as, greater than, or smaller than, the diameter of the base section.
Cross sections other than circular may be used, such as cross sections which are of a square or other polygonal form, with or without curved portions on at least some corners. The cross section may be of constant form, in terms of horizontal extent, along the vertical extent of a locating portion. The cross section may vary in a regular manner along the vertical extent of a locating portion, in which case the locating portion could for example be in the form of a pyramid. The variation may be such that the larger dimension part is adjacent the base of the locating portion, adjacent the tray surface, or adjacent the top of the locating portion, remote from the tray surface. The cross section may vary along the vertical extent of a locating portion in a non-regular manner, and may for example provide a base section having a first size in a horizontal plane, a central section with a smaller size in a horizontal plane than the base section, and a top section with a size in a horizontal plane which is greater than that of the central section, and may be the same as, greater than, or smaller than, the size of the base section.
The base of the tray is preferably also of resilient material, and may be of the same material as the locating portions. However, the tray and locating portions may be of different materials, and indeed the locating portions themselves may be of differing materials. All materials may be unitary materials or composites, and different regions of the tray and/or the locating portions may be of different materials.
Whilst the tray is adapted to receive lights, it can be used to receive other waste electrical or electronic goods, such as mobile telephones, personal digital assistants or the like.
In some embodiments, the material used may be plastics such as a foamed or expanded plastics material—for example expanded polystyrene; a natural or synthetic rubber; or a compressed fibrous material such as paper pulp. In one embodiment, there is a tray with locating portions which is formed from compressed paper pulp, and there is a supporting layer of another material such as a sheet of plastics or metal to support the tray. The supporting layer could be bonded to the tray, but in one embodiment is detachable from the tray, so that the tray itself can be disposed of after a period of use and replaced, whilst the supporting layer is re-used. References below to the tray encompass the tray alone, or the tray with a supporting layer.
The tray may be received by suitable locating portions within the container, preferably such that the tray can be slid in to the container in a horizontal direction. There could be grooves in opposing walls of the container, or longitudinal supports projecting from opposing walls, or spaced supporting portions arranged in a longitudinal direction, projecting from opposing walls. The locating portions preferably define slots or the like so that the tray is restrained from vertical movement in either direction. The container preferably has a door which can be opened to provide horizontal access to the tray. In such an arrangement, there may be a plurality of locating portions which are spaced vertically, so that a plurality of trays can be placed in the container, spaced vertically from each other. However, in an alternative arrangement, a tray adjacent the upper part of the container could be accessed from a lid at the top of the container.
In use, lights such as fluorescent tubes and/or bulbs, spotlights and so forth—whether conventional incandescent units or low energy units, will be arranged in suitable orientations in the tray, engaged resiliently by the locating portions so as to resist rolling around and other forms of dislodgement. Additionally or alternatively, other items such as mobile telephones can be placed in the tray. To provide additional security against breakage, there may be provided a resilient layer of material disposed above a tray. This material could be provided on the base of a tray above, or of a supporting layer for a tray above. In the case of a tray with no other tray above, the material could be provided on another portion of the container, above the tray. The resilient material can be of any of the resilient materials discussed above such as compressed paper pulp. The material could be in the form of a simple sheet, or alternatively the material could be provided with locating portions which can have any of the features discussed above. Thus a tray could be two sided, if necessary with a supporting layer between the two sides.
Whilst the container could be used exclusively for lights or other small waste electrical and electronic waste products, and intended to carry a full load of trays, in some preferred forms the container is intended to have only an upper portion occupied by one or more trays, there then being a lower region which can contain larger waste products such as televisions, radios and so forth. There may be a fixed or adjustable blanking plate or wall between that part of the container and the part containing the or each tray. Where there is such means defining a barrier with the region containing the tray, that may be provided with a disposable absorbent layer to catch any undesirable or toxic substances that may have come from the lights or other waste products in the tray, to prevent those substances contaminating other products in the container.
The container can preferably be stored and transported (empty of waste products) in a collapsed condition, and then erected for use. In one preferred embodiment, there is provided a collapsible container which comprises a top member defining a top of the container, a base member defining a base of the container, two side walls, a back wall and a front wall; wherein (a) in an erected state of the container the two side walls, the back wall and the front wall are connected to the top member and the base member to form a substantially rigid structure, with at least part of the front wall being movable pivotally between a closed position preventing access to the interior of the container, and an open position in which there is access to the interior of the container; and (b) in a collapsed state of the container the top member and the base member are in contact and interlocked together, so as to define a storage space in which are located the two side walls, the back wall and the front wall.
In one, embodiment of such a container, the top member and the base member are provided with latching portions that cooperate with portions on the front wall when the container is in the erected state, to hold the front wall in the closed position. In such an arrangement, when the container is in the collapsed state the latching portions on the top member and the base member may be used to latch the two shell portions together.
The tray for lights and other small items may be connected to at least the side walls when the container is in the erected state, and may also be contained in the space defined by the top and base members when the container is in the collapsed state. The arrangement is preferably such that in the erected state the tray is in the upper part of the container. In the erected state of the container, the top member may be pivotal upwardly to provide access to the tray and there may be a latch mechanism between the top member and a wall of the container to hold it in the closed position. There may be a barrier between the tray and the remainder of the container—for example provided with disposable layer of absorbent material for any toxic liquids—and this may also be contained in the space defined by the top and base members when the container is in the collapsed state.
The top member and the base member may be provided with cooperating protrusions and recesses, or like cooperating elements, in their upper and lower faces respectively, so that when a plurality of the containers are in the collapsed state they can be stacked on top of each other, with the cooperating elements resisting lateral slippage of the containers with respect to each other.
The lower part of the base member may be provided with open ended spaces to receive the times of a fork lift truck. The spaces may run from front to back, or from side to side, or preferably in both directions so as to maximise versatility in terms of accessing the containers with a fork lift truck.
In general in a number of embodiments the lower part of the container may have a cross section corresponding approximately to a conventional pallet, and may be adapted for transport by a fork lift truck. Additionally or alternatively, the container may have wheels (which expression includes rollers, casters and the like) to assist in movement and positioning, and the arrangement may be such that these can be locked when desired.
The interior base of the container, such as the interior of the base member in the embodiment discussed above, may be provided with a disposable absorbent layer to catch any undesirable or toxic substances that may have come from products within the container.
In general it is preferred if the material(s) of the tray and/or a supporting layer for the tray, and/or other portions of the container have been recycled and/or are recyclable.
The top and base members may in the form of cooperating shell portion portions which when located together form the space to contain the other panels. Alternatively, one of the top and base members could define a space to contain the panels and the other of the members could serve as a cover for the space. In one preferred embodiment the base member defines the space to hold the panels and the top member serves as a lid which is attached to the base member when the container is in the collapsed condition. In one arrangement, the base member defines an interior portion below where the panels will be located, to hold one or more trays when the container is in the collapsed condition.
The base member may be attached to the base of the front wall by a first hinge along a front part of the base member, to the base of one side wall by a second hinge along one side part of the base member, to the base of the rear wall by a third hinge along a rear part of the base member, and to the base of the other side wall by a fourth hinge along the other side part of the base member, with the vertical positions of the first, second, third and fourth hinges being displaced from each other upwardly, such that the front, rear and two side walls may be folded inwardly to overlie each other in the collapsed state of the container. In such a condition the top member can be connected to upwardly directed portions of the base member, overlying the folded walls of the container.
It will be appreciated that references to horizontal and vertical do not imply that directions or surface are strictly horizontal or vertical in a geometrical sense, and encompass generally upwards and generally level, for example. Similarly, references to front, rear and sides are relative only. Thus, for example, in defining the invention the front wall may be defined as the wall providing access to the interior of the container and other wall designations are relative to that. However, for aesthetic or other reasons in practice an alternative wall might be proposed as the “front” wall, in which case the wall with the opening might be the rear or a side wall relative to that designated front wall.
The invention may be viewed from many aspects. For example, preferred forms of the collapsible container may be of use even if no tray is provided and it is to contain only larger waste equipment. Thus, viewed from another aspect of the invention there is provided a collapsible container for the storage and transport of waste electrical and/or electronic equipment, comprises a top member defining a top of the container, a base member defining a base of the container, two side walls, a back wall and a front wall; wherein (a) in an erected state of the container the two side walls, the back wall and the front wall are connected to the top member and the base member to form a substantially rigid structure, with at least part of the front wall being movable pivotally between a closed position preventing access to the interior of the container, and an open position in which there is access to the interior of the container; and (b) in a collapsed state of the container the top member and the base member are in contact and interlocked together, so as to define a storage space in which are located the two side walls, the back wall and the front wall.
A further feature disclosed herein, which can be used alone or in combination with any of the features discussed above, is a plurality of battery compartments in a container, which can be accessed via appropriate apertures in a lid of the container. Thus, viewed from another aspect the invention provides a container for waste electrical batteries, the container being provided with a horizontal shelf and one or more vertical dividers which cooperate to define a plurality of battery compartments, there being a plurality of apertures in the lid which provide access to respective ones of the battery compartments, and the or each battery compartment below the shelf communicating with the corresponding aperture in the lid by means of a tube which passes through a battery compartment above the shelf and through the shelf. Preferably, the container is also provided with at least one horizontally disposed tray as described above, provided with an array of upwardly projecting resilient locating portions, adapted to receive a plurality of lights in a plurality of different orientations in which the lights will occupy spaces between the locating portions and will be gripped by the locating portions. Preferably there is a space below the battery compartments or the battery compartments and the tray, for larger items of electrical or electronic waste. With the exception of the inclusion of the battery compartments, which may be provided as separate, removable modules with side walls to retain the batteries, the container may be as described earlier.
Embodiments of the invention will now be described by way of example only, and with reference to the accompanying diagrammatic drawings, in which:
Referring now to the drawings, in
The side panels, front panel and rear panel are connected to the top and base shell portions in a manner that enables the container to be collapsed, for example being detachable from the shell portions. The front panel 3 is pivotally attached to the top and base shell portions so that it can open as shown in
As shown in
The base of the tray may be provided with an absorbent layer to trap any liquids that escape from the items.
In this embodiment, the top of the main part of the container is provided with a partition 40, on which is supported a removable tray 41 carrying protrusions and in a form corresponding to that of tray 17 described with respect to the previous embodiment. The top shell portion can pivoted upwardly with respect to rear panel 35, as shown, to gain access to the tray 41. In the closed condition the top shell portion is held closed by a latch 42. In this arrangement the items in the tray are isolated from the remainder of the container.
In the collapsed state of this embodiment of container, the four panels, the partition and the tray are contained in the space define by the top and base shell portions when they are connected together.
Within the container is a tray 53 which may be as described earlier, with protrusions to hold lights and other small items in place, and which in this Figure is shown as being accessible through the top of the container.
Although in this embodiment the container is shown without wheels, the base may have mountings to enable optional wheels to be added.
Although each on the panels 45, 46, 47 and 48 is hinged to the base member 44, and the lid is hinged to the rear panel 48, the panels can all be detached from one another. This means that if a panel is damaged, it may be replaced by a spare panel. Effectively, the container is modular.
In a preferred embodiment of this arrangement, the lid 49 remains attached to the rear panel 48 and thus folds over the rear panel when it is folded in. For the lid to serve as a lid for the container in the collapsed condition, the side wall portion 60 should then the highest of the four side wall portions. It is not essential for the lid to be hinged to the rear panel and it could be hinged to another panel, although preferably access should still be possible through the lid when standing at the front of the container. Thus, in
In any event, there is preferably means to lock the lid in position on top of the other panels when the container is in the collapsed state.
As shown in
A further embodiment of the container is specifically adapted to receive batteries, of the type used typical household products such as torches, portable radios, MP3 players and so forth. There may for example be four compartments to handle four commonly used sizes, such as AAA, AA, C and PP3. However, as many sizes as necessary can be coped with, the number of compartments can be varied and sizes might be combined, for example so that AAA and AA are kept together, and other compartments handle sizes C, D and PP3 respectively. There could be a separate compartment for watch type batteries also. To provide the compartments the interior of the container is preferably divided both horizontally and vertically, and in a preferred embodiment by a shelf and by one or more dividers both above and below the shelf. A divider could for example run diagonally from one corner of the container to the other. The container could be exclusively for handling batteries in this manner, or could also handle other waste equipment beneath a second shelf below the batteries, and/or could also include a try for lights and other small items as discussed above. Preferably access to the battery compartments is through the lid of the container, which could have appropriately sized (and marked) apertures for the battery sizes. Apertures for compartments above the shelf could be directly through the lid, and apertures for compartments below the shelf could be via tubes passing through the compartments above and the shelf. There could be a series of shelves defining three or more layers of compartments, with tubes passing through multiple shelves to the compartment concerned.
With the exception of adaptation to incorporate the battery compartments, the container may otherwise be as described in respect of any of the other embodiments.
There are thus provided embodiments of a versatile container for waste electrical and/or electronic equipment, which is adapted to handle lights and other items in an effective manner and which can be collapsed and erected. In the preferred embodiments of the invention the container has solid walls and in the erected condition presents an effective barrier to small components, broken glass and so forth escaping from the container. Whilst steps could be taken to provide effective sealing of the container to prevent escape—or entry—of liquids, this is generally considered unnecessary, particularly if there is absorbent material within the container to trap such liquids.
Embodiments of the invention provide a collapsible container for the storage and transport of waste electrical and/or electronic equipment has at least one tray provided with an array of upwardly projecting resilient locating portions. The tray receives relatively small waste equipment such as electric lamps, mobile telephones or the like in a number of different orientations in which the items will occupy spaces between the locating portions and will be gripped by the locating portions. The container may be collapsible and comprise a top, a base member, two side walls, a back wall and a front wall. In an erected state of the container the two side walls, the back wall and the front wall are connected to the top and the base member. An access opening is provided by all or part of the front wall and preferably access is also, possible via the top. In the collapsed state of the container the top and the base member cooperate, for example being in contact and interlocked together, so as to define a storage space in which are located the walls of the container and the tray. Compartments specifically adapted to receive electric batteries may also be provided.
