Technical Field This specification discloses a container. The disclosed container may be used for the same purposes as, and instead of, common wooden pallets and intermediate bulk containers,

Background Art

Pallets are used for the storage and/or transport of goods and other substances. The pallets are usually made from wood although plastic pallets are becoming more common. Once goods have been loaded onto a pallet the pallet can be lifted and moved short distances by a fork lift truck. The pallet can be transported large distances by being loaded onto or in road or rail vehicles, marine vessels or aeroplanes. To assist in retaining goods on pallets is also know to wrap a laden pallet in plastic film.

When a pallet carries goods or materials that form a fiat surface and have weight bearing characteristics it is possible to stack one loaded pallet on top of another. This assists in reducing overall transport costs as it enables a vehicle such as a tray top truck to carry more goods laden pallets than if stacking were not possible. However this is not possible when for example a pallet is loaded with a machine or other goods of irregular shape or tha may otherwise not be suitable for bearing the load of an additional stacked pallet.

An intermediate bulk container (IBC) is an industrial container used to carry bulk liquids and particulate materials. One common form of IBC consists of container made of a plastics material (e.g. polyethylene) housed within a rigid open frame. An IBC can be loaded onto pallet. One relatively common problem is that the IBC is prone to accidental piercing by a fork lift truck. Also when carrying hazardous materials, after the IBC has been emptied, there usually remains some residue of the hazardous materia). As a consequence the emptied IBC must still be transported in accordance with the sam requirements as a full. IBC.

Detailed Description of Specif ic Embodiments

Figures 1a - 1 depict an embodiment of the disclosed container 10 in respective different configurations. The container 10 in this embodiment comprises a bottom wall 12, a top wall 14, and four side walls 18a - 16d {hereinafter referred to in general as "side walls 16").

When the coniainer 10 is in the erected condition shown in Figure la the bottom wall 12, top wail 14 and side walls 6 form an enclosed storage space. in this embodiment the side walls 16a, 16b and 16c are coupled to the bottom wall 2, and the top wall 14 is coupled to both the side wall 16b and the side walls T6d> By virtue of this coupling the container 10 can be reconfigured to the lay flat condition shown in Figure 1 b where the respective walls overlie each other as well as the bottom wail 12, Thus the container 10 can be reconfigured between the erected condition shown in Figure 1a and the lay flat condition shown in Figure l by simply pivoting or folding various walls relative to other walls. All of the walls 12, 4 and 16 remain coupied together in these two configurations.

The container 10 has a lid structure 18 comprising two ltd panels 20t and 20f. The first lid panel 20t forms a part of the to wail 14. indeed, in this embodiment the first lid panel 2Gt constitutes the whole of the top wall 14. The second lid panel 2Qf forms at least part of one of the side walls I6d. More specificatiy i this particular embodiment the second lid panel 2 Of constitutes t e whole of the side wall 16d. Thus in this

Substitute Sheet

(Rule 26) RO/AU embodiment the first |id panel 20t is one and the same as the top wall 14, and the second iid panel 20f is one and the same as the side wail 18d. Accordingly the lid structure 18 can also be considered as comprising the top wall 14 and the side wail 16d.

The first lid panel 20t is ptvoialiy coupled to the side wall 18b. In addition the first lid panel 20t is detachably coupled to the second lid panel 20f . By virtue of the detachable coupling it is possible to decouple the first lid panel 20t from the second lid panel 20f.

When the container 10 is in the erected condition the iid structure 18 can have one of several different configurations. These configurations include a closed configuration shown in Figure 1a, a fop load configuration shown in Figure 1c, and a front load configuration shown in Figure 1d. As wili be explained with reference to a second embodiment the front load configuration shown in Figure 1d may be one of two dffferent front load configurations, in the second front load configuration the second lid panel 20f is pivoted to lie on top of the first iid panel 20t, the first iid panel 20t remaining unmoved, parallel to and overlying the bottom wail 12. In the closed configuration shown in Figure 1a the lid structure 18 is arranged so that the first ltd panel 20t and the second lid panel 20f constitute the top wall 14 and side wail 16d and form, together with the remaining waits of the container 10 _s the enclosed storage space. When the lid structure 18 is in the top load configuration shown in Fig. c, the first lid pane! 20t is: detached from the second lid panel 20f; and, the pivoted to a position enabling top loading of the container 10. In this condition the second lid panel 20f forms part, and indeed the whole, of the side wait 16d and remains disposed between the side walls 16a and 18c.

In the top load configuration depicted in Figure 1c the first lid panel 20t is shown nearly directly above the side wall 16b, However the first lid pane! 201 will not normally be he!d in this position. Rather this may be a transition position either back to the closed configuration show in Fig. 1a or to a rest position where the lid panel 20t is swung further so as to lie face to face with the side wall 8b on an outside of the container 10.

Substitute Sheet

(Rule 26) RO/AU Figure 1d depicts the lid structure 18 in a first of two possible the front load

configurations. In the first front load configuratio the first and second lid panels 201 and 20f remain connected to each other. Further, the lid panels 20t and 20f can be moved and in this instance pivoted relative to each other to open the container 10 and enabling front loading of goods or materials onto the bottom wall 12. More particularly both the first and second panels 20t and 20f are moved from their respective closed configuration positions so that they are in a substantial face to face relationship, with the second lid panel 20f resting on the to edges of the side panels 16a and 16c. Figures 2a-2f depicts the bottom wall 12 of the container 10. The bottom wail 12 is configured to receive members of a lifting apparatus such as the forks of a forklift truck. This enables lifting of the container 10 from beneath the bottom wail 12, This is facilitated by providi g the bottom wall 12 with a plurality of spaced apart legs 22. In this instance the bottom wall 12 has nine legs 22 arranged in a three by three matrix like pattern as shown most clearly in Figure 2b. This arrangement of legs 22 forms a first pair of channels 24a and a second pair of channels 24b {hereinafter referred to in general as "channels 24Ί. Each respective pair of channels 24 is able to receive the forks of a forklift truck. Further each pai of channels open onto opposite sides of the container 10; and the pai of channels 24a is perpendicular to the pair of channels 24b. Thus the base 12 and consequently the container 0 can be lifted by a forklift truck of other lifting apparatus driven or moved toward the container 10 in a direction front on to any one of the four side walls 16.

The bottom wall 12 is further configured to form a bunded pallet This is achieved by configuring the bottom wall 12 to form a liquid receiving receptacle 26. Thus any liquid which spills or otherwise leaks from any item loaded onto the bottom wall 12 is able to flow info and be contained within the receptacle 26.

The receptacle 26 is defined between four waits 28a ~ 28d (hereinafter referred to as "walls 28") of the bottom panel 12. In order of height the wail 28c is the lowest followed by walls 28d and 28a which are of the same height, and then wall 28b which is the highest of the walls 28. Each of th walls 28a, 28b and 28c Is formed with integral hinge portions 30, The hinge portions 30 are in the form of spaced apart raised tubular structures. As will be explained in greater detail later, the hinge portions 30 cooperate with complementary hinge portions on side walls 16a, 16b and 16c to form hinges that couple the corresponding side wails to the bottom wall 12 and also enable relative pivoting motion.

Substitute Sheet

(Rule 26) RO/AU The wall 28d is not provided with hinge portions. Rather it forms a lip or wall delimiting the forward extent of the receptacle 28 and also acting as a stop for the second lid pane! 2 Of (side wall 16d).

A serpentine channel 32 forms part of the liquid collection volume or space of the receptacle 26, The channel 32 winds between alternating and spaced apart ribs 34 and 38 formed in an inside of the bottom panel 12. The serpentine channel 32 is depicted by way of dots in Figure 2c. The ri s 34 and 36 have respective planar surfaces 38 and 40. These surfaces are of the same height as each other. Thus together the ribs 34 and 36 form a support surface on the bottom waii 12.

A drainage opening 42 is formed in the bottom wall 20 and opens onto a middle leg 22 adjacent the wall 28d. The drainage opening 42 communicates with the serpentine channel 32 via an internal conduit 44 (see Fig.2f). A stopcock or other valve (not shown) can be coupled to the drainage opening 42 to control the drainage of the receptacle 26.

Various recesses and pockets are formed on the bottom wail 12 for different purposes. One set of recesses 46 (see Figures 2a and 2b} is provided for seating or otherwise receiving identification tags such as RFID tags. Respective second recesses 48 are formed, one in each legs 22 at the opposite ends of the wall 28d. The recesses 48 receive parts of a latch mechanism {described later) which may be used to lock the container 10 in the closed configuration. Rockets 49 are also provided in the bottom wall 12 along the wall 28d on opposite sides of a central one of the legs 22.

Figures 3a - 3d depict an embodiment of the side wall 16c. Th side wall 16c is in this embodiment in the form of a single one piece panel. The side wall 16c has an inner face 50 and an outer face 52. When the container 10 is in the erected condition the face 52 is on an outside of the container 10. The inner face 50 is formed with a plurality of laterally extending spaced apart channels 54. A plurality of recesses 56 is formed in the inner face 50, Hinge portions 58 are fonTied alon one edge of the panel 16a, The hinge portions 58 are in the form of spaced apart tubular structures. In the container 10, the hinge portions 58 interleave with corresponding hinge portions 30 along the wail 28c. A pivot pin or axle (not shown) can then be passed through the interleaved hinge portions 30 and 58 to form hinge coupling between the wall 16a and the bottom wall 2.

With reference to th container 10 being in the erected condition, the lip 59 runs along an upper edge of the wail 16c; the tip 60 extends along a side edge of the side wall 16c adjacent the side wall 1Sd; and the lip 62 runs along an opposite side edge of the side wall 16 c adjacent the side wail 6b, The lip 59 is formed with a cut out 64. A number of depressions 86 are formed along the iip 62.

The outer surface 52 is formed with a plurality of longitudinally extending channels 88. A central diamond shaped recess 70 is also formed centrally in the outer surface 52. The recess 70 may receive signage which may for example contain warnings or a description of contents or intended contents of the container 10. Also cutaways 69 are provided on the side wail 16c to enable lifting/pivoting of the side wall 18c from the lay flat condition to the erected condition.

Latch recesses 71 are formed in the outer face 52. The latch recesses 71 are in alignment with respective recesses 56 on the inner face 50.

The side wall 6a has a configuration which is a mirror image of the side wall 16c,

Figures 4a and 4b depict the side wall 18b. In the present embodiment the side wall 18b can be considered to form the backside wall or more simply the back wail of th container. For the purposes of more easily differentiating the side wall 16b from the side wails 16a and 16c, the side wall 16b will be also referred to as the back wall 16b.

The back wail 16b is of generally the same configuration as the wall 16a and 16c having an inner fac 50 with and an outer face 52. The inner face has a plurality of laterally extending spaced apart channels 54; and the outer face has a plurality of Iongitudinalty channels 68. Hinge portions 58 similar to those of the side waifs 6a and 16b are provided along one edge of the back wall 16b.

However the back wall 16b differs from the side walls 16a and 18c as follows. The back wall 18b is formed hinge portions 72 along an upper edge 73 opposite the hinge portions 58. A further difference in the back wait 16b is the provision of opposite side lips 74 that extend perpendicular to the plane of its inner and outer faces 50 and 52. The lips 74 are formed with raised dimples 76 on a side internal of the container 10 when in the erected condition. The dimples 76 are located so as to seat within the

(Rule 26) RO/AU depressions 86 formed on the walls 18a and 16c. A rectangular depression 75 is also formed in the inner face 50. The depression 75 can receive a sign that is viewable when the lid structure 18 is in the front load configuration. Figures 5a and 5b depict one possible configuration of the side wall 8d. The side wall 16d has a hybrid configuration in comparison to the side walls 16a/16c; and the side wall 16b. In this embodiment the side wall 18d can be considered to form the front side wall or more simply the front wall of the container 10. For the purposes of more easily differentiati g the side wail 16d from the side walls 16a and 16c, the side wall 16b will be also referred to as the front wall 16b,

The front wall 16d is in the form of a single panel having an inner surface 50 with transverse channels 54 and an outer surface 52 with longitudinal channels 68. A lower edge of the front wall 16d is formed with a pair of spaced apart lugs 80. The lugs 80 are received within the pockets 49 when the container 0 is i the erected conditio with the lid structure 18 i the closed configuration. The front wall is also provided with four recesses 56 on its inner face 50 and corresponding aligned recess 71 on its outer face 52. The front wall 16d has a plurality of spaced apart hinge portions 58 along an edge opposite the lugs 80. The two remaining edges of the front wall 16d are formed with lips 84 that extend in a plane transverse to that of its inner and outer faces 50, 52. The lips 84 are configured so that when the lid structure 18 is In the closed configuration the lips 84 overlie the lips 80 oh the side walls 16a and 16c,

Figures 6a and 6b depict one configuration of the top wall 14, The top wall is formed as a single panel. The top wall 14 has an inner face 50 with transverse channels 54, and an outer face 52 with transverse channel 68, The top wall 14 is also provided with four recesses 58 on its inner face 50 and corresponding aligned recess 71 on its outer face 52,

Figures 7a, 7b and 7c depict a hinge mechanism 96 that demourrtably couples the fop wall 14 to the front wall 16d. As previously explained the combination of the top wall 14 and the front wall 16d forms the lid structure 18, Further in this embodiment the top wall 14 and the front wail 6d also constitute the first lid pane! 20t and 20f respectively.

The hinge mechanism 96 is movable between an engaged position shown in Figure 7b where the first and second lid panels 20t and 20f are pivotally coupled together, and a disengaged position shown in Figure 7c where the first and second lid panels 201 and 20f are disengaged from each other. When the hinge mechanism 96 is in the engaged position the first and second lid panels 20t and 2Qf can be pivoted relative to each other.

When the hinge mechanism 96 is in the engaged position the lid structure 18 can be moved to the front load configuration shown in Figures 1d and 7a. In this front load

(Rule 26) RO/AU configuration both of the lid panels 20t and 20f are moved from (or displaced reiative to) their respective locations when the lid structure 18 is in the closed configuration shown in Figure la. This front load configuration enables loading from the front of the container. Additionally the top of the container 10 is opened to allow easy access to the rear of the storage space.

The hinge mechanism 96 comprises two members in the form of bolts 98. in Figures 7b and 7c only one of the bolts 98 is depicted . A second of the bolts is provided in an opposite corner of the panels 20t and 20f.

From Figure 7b it will be seen that when the hinge mechanism 96 is in the engaged position the bolt 98 extends partially within the hinge portions 88 and 58 of the first and second lid panels 20t and 2Df respectively. However when the hinge mechanism 96 is in the disengaged position shown in Figure 7c the bolt 98 resides within the hinge portion 88 and is totally withdrawn from the hinge portion 58. This enables the second lid panel 20f to be physically detached or decoupled from the lid pane! 2Gt

A lever 100 is attached to the bolt 98 and extends through a slot 102 formed in the lid panel 20t (i.e. top wall 14). A handle or knob 102 is attached to the end of the lever 100 opposite the boit 98. A friction washer 104 between the knob 102 and the lever 100 creates friction which retains the bolt 98 in a position in the absence of the application of an external force. in use, a user will be able to apply a force on the knob 102 overcoming the friction of the washer 104 to slide the bolt 98 as required to engage or disengage the hinge mechanism 96.

Figure 1c depicts the container 10 with the hinge mechanism 96 in a disengaged position and the lid structure 18 in the top load configuration. In this configuration the second lid panel 20t/front wall 1 ^' 6d is coupled to the upper side wall 16a and 16c, Thus in this configuration the container 10 is in the form of an open top bm.

The containe 10 also comprises a latching system 110 (refer to Figures 8a and 8b) which is arranged to lock the container 10 in the erected condition to prevent unauthorised access to the enclosed storage space. The latching system 110 comprises a plurality of latch mechanisms 112 which are fixed to respective associated walls 12, 14 and 16, Each latch mechanism 112 has a latched state where the !ateh

Substitute Sheet

(Rule 26) RO/AU mechanism latches two associated wails together and an unlatched state enabling the associated walls to foe moved relative to each other.

Each latch mechanism 112 has a catch 1 4, lever 120 and latch member 118. The catch, which is in the form of a plate with a hook at one end, is attached to one wall and a latch body 18 that comprises the lever 120 and latch member 118 is attached to an adjacent wall. The latch member 118 is pivota!ly connected to the lever 120 which in turn is pivotaiiy connected to a bracket attached to the associated wall. Figure 8a depicts the latch mechanism 112 in the disengaged state where the latch body 16 is disengaged from the catc 114. In particular, the latch member 118 is spaced from the catch 114.

Figure 8b depicts the latch mechanism 112 in the engaged or locked state. Here the latch body 116 engages the hook plate 14. Moreover the latch member 118 is engaged with the catch 114 and the lever 120 has been pivoted down to lie

substantially flush with the associated side wail 16c. Now the walls 16c and 14 are latched together. An eye 122 extends through a central region of the lever 120 when the latch mechanism 112 is in the latched state, A secure lock such as a padlock can be engaged with the eye 122 thereby preventing the lever 120 from being pivoted upwards. This in effect locks the latc mechanism 112 to prevent unauthorised access to the storage space.

Each of the catches 14 and the latch bodies 16 are disposed within corresponding recesses 71 formed on the outer faces 52 of the respective walls. Additionally, in order to strengthen the connection of the latching system 110 to the container 10 metallic fastening plates (not shown) are also provided within respective recesses 56 formed o the inner faces 52 of the corresponding walls. Bolts (not shown) fasten the catches 114 and the latch bodies 116 to the fastening plates in the recesses 56. The recesses 56 and 71 are configured to neatly fit the respective parts of locking mechanism and in a manner to lie below the exposed surface of the outer faces 52. This assist in protecting the latch parts from being tampered with. in this particular embodiment the latching system 110 is formed with ten latch mechanisms 112, Two latch mechanisms 1 12 operate between the top wall 14 and the side wait 16a; two latch mechanisms 1 12 act between the side wail 16a and front wall 16d; two latch mechanisms 112 act between the bottom wall 12 and the front wail

Substitute Sheet

(Rule 26) RO/AU 16d; two latch mechanisms 1 12 act between the top waif 14 and the side wail 16c; and two latch mechanisms 12 act between the side waif 16c and the front wail 16d. in addition to providing a degree of security to the contents of the container the iatching system 1 10 also provides th container 10 with increased structural strength. This is most evident when all the latch mechanisms 1 12 are in the latched state (irrespective of whether padlocks are fitted to the eyes 122) and the container 0 is accidentally dropped or run into by a vehicle. The iateh mechanisms 1 12 will tend to keep the wails between which they operate in a fixed spatial relationship.

In order to enable the container 10 to be used for liquids or particulate matter, the container 10 may incorporate a bladder 130 as shown in Figure 9. The bladder 130 is made of a shape whic substantiall conforms to the inner faces of the wails 2, 14 and 8 of a container 10 when in the erected condition with the lid structure 18 in the closed configuration. The bladder 130 has an inlet 132 with a removabl fid (not shown). The inlet 132 is accessible when the lid structure is in the to load

configuration.

The bladder 130 is made of a liquid impervious material. Further, the material from which the bladder 130 is made can be pliable and/or flexible, in this way, when the container 130 has been emptied: of its contents the bladder 130 may be flattened to take up a volume substantially e ual to its footprint area times about four times the thickness of the material from which the bladder 10 is made. When in this condition the inlet 32 can of course be closed with its lid. Therefore any residue within the b!adder 130 is maintained within the flattened bladder. However now the container 10 can also be moved to the collapsed or fay flat position as shown in Figure 1d.

Therefore once the container 10 with bladder 130 has been emptied it can be collapsed to a substantially smaller volume therefore greatly reducing further transport or carting costs.

Figures 10a and 10b depict a demountable divider 140 that may be incorporated in embodiments of the container 10. The divider 140 is configured to engage with the inner faces 50 of two of the side panels 16a and 16c. Further, the divider 140 is self- supporting within the container 10 so as to divide the storage space into a plurality of subs paces.

The divide 140 comprises two panels 142 and 144 which are pivotalty coupfed

Substitute Sheet

(Rule 26) RO/AU together by a pivot pin 146. Opposite ends 148 and 150 of the divider 140 are configured to seat within the channels 54 on the inner faces 50. Also, the panel 142 is provided with a flange 152 that extends beyond the pivot pin 146 and is arranged to abut against the panel 144 when the two panels 142 and 144 are substantially parallel. Thus the flange 152 acts to hold the divider 140 in a substantially horizontal plane as shown in Figure 10b. In this manner the divider 10 is self-supporting within the container 10.

Each of the walls 12, 14 and 18 is made as an individual pane!. In some embodiments these panels can be made from plastics or composite materials using a variety of known manufacturing techniques including blow moulding, injection moulding and rotor moulding. Different types of plastics materials of different thickness may be used depending on the specific use of the container 10. Non-limiting examples of materials from which the walls 12, 14 and 18 can be made include: various types of

polypropylene such as HOPE, DPE, LDPE; composite materials such as glass or carbon fibre composites; and aluminium.

The container 10 is well suited for use as a universal segregation pallet. In one embodiment the container 10 may have a width of about 1 ,150mm, a depth of about 960 mm, and a hei g ht of about 1,160mm. I one embodiment the load carrying capacit of the container with the above dimensions may be in the order of one tonne. This equates for example to approximately sixty five standard car lead acid batteries. in order to place the container 10 in a lay flat condition from the erected condition the lid structure 18 is opened and moved to the front load configuration shown in Figure Id and then subsequently pivoted rearwardiy a further 180° so that the lid structure 18 lie face to face with the back wall 16b. Next the side panel 16c is pivoted 90* inwardly so as to overlie the bottom wail 12, The opposite side wail 16a is now pivoted 90° inwardly to lie on top of the side waif 16c, Next the back wall 16b together with the folded lid structure 18 is pivoted forward by 90° so as to lie on top of the side wail 16a. in the event that a divider 140 is installed in the container 10, the divider 140 will be removed prior to collapsing the container 10 to the lay flat condition, in some embodiments, the bottom wall 12 may be configured so that the divider 140 can be received within the receptacle 26 prior to folding down the walls 16 and 14 to place the container 10 in the lay fiat condition. In such embodiments the divider 140 is therefore retained within the lay flat container rather than having to be separately handled.

Substitute Sheet

(Rule 26) RO/AU Whilst a specific embodiment of the container 10 has been describee!, it should be appreciated that the container 10 ma be embodied in many other forms. For example in one form or variation the first lid panel may be formed as only a part of the top wail 14. With reference to Figure 1a this may be achieved for example by forming the top wall 14 as two separate pieces which are permanentiy hinged together along axis AA. Thus for example the top 14 will be formed as a top wail portion 14* and a first lid panel 20t'. In such an arrangement the front load configuration of the lid structure 18 is the same as shown in Figure 1 d. However the container can now have two different top load configurations. In both the top load configurations the entirety of the top wail 14 is decoupled from the front wall 18 by use of the hinge mechanism 96 as described above. Howeve after this decoupling either:

* the entirety of the top waii 14 can be pivoted through 270° to open the entirety of the top of the container 10; or

« the first lid portion 20t' can be pivoted about axis AA through 180° so as to lie on top of the top wall portion 14'. Now one half of the top area of the container 10 is open. Further, with reference to Figures 1 1a and 11b, by slight modification of the hinge arrangement coupling the lid panels 20t and 20f two different front load configurations are possible. in Figures 1 1 a and 11 b each of the lid panels 20t and 20f is formed with hinge portions 58. However the hinge portions 58 do not interleave with each other, rather are disposed side by side. Two links 160 extend between the hinge portions 58 on the lid panels 20t and 20f. A hinge mechanism similar to hinge mechanism 96 can then be incorporated to decouple the lid panels 20t and 20f in th same manner as described hereinabove.

The first front ioad configuration possible via the hinge arrangement of Figure 11 b is identical to that as show in Figure 1 d. However in a second front load configuration shown in Figure 1 1a the front wajM 6d second fid panel 20f is pivoted through 270° to lie on top of the first lid panel 20i and parallel to the base wall 1 . The second front load configuration enables a further container 10 to be stacked on top of the opened lid structure 18. The lid structure of the stacked container can be moved to either the first front load configuration shown in Figure Id or the second front load configuration

Substitute Sheet

(Rule 26) RO/AU shown in Figure 11 a. Now two containers 10 can be stacked on top of each other and can both be front loaded. in a further modification of the embodiment shown in Figures 11a and 1 l tabs 80a may be formed on sliders 99 so as to be slid into and out of the pockets 49.

Additionally a recessed handle 101 can be formed in the front panel 16d. With these modifications and referring to figure 11 b is now possible to fully remove the front panel 16d by releasing the hinge mechanism and sliding the slide tabs 99 upwardly disengaging the tabs 80a from the recesses 49. Assuming the latches 110 associated with panel 16d are disengaged a user ca now simply pull off the front panel 6d using the handle 101 , Resultant container will look like that shown in figure 11a but without the panel 16d lying on top of the panel 14.

Further, the bottom wall 12 is depicted as being provided with a plurality of channels 24 created by a matrix of spaced apart legs 22 in order to facilitate the lifting of the container 10 with a forkiift truck. However this function can be equally achieved by modifying the bottom wall 12 in a manner so that the channels 24 are replaced with hollow bo sections for receiving the forks of a forkiift truck. I yet a further variation, with reference to the provision of a bladder 130 shown in

Figure 9 it is possible to form the top wall 14/lid panel 20t with a removable waif portion which overlies the inlet 132. in this way the bladder 130 can be accessed without opening the container 10. in such a variation the removable cover may also be provided with a latching mechanism to prevent unauthorised access to the bladder 130.

Also the hinge mechanism 96 can be configured in many different ways to produce the same effect. In one very simple alternative a single elongated shaft can be used to pass through the hinge portions S8 and 98 to create the pivot coupling between the top and front walls 14. 16d, A fixed stop can be provided at one end of the shaft and a reteasab!e stop at the other end such as a nut, a split pin or cotter pin at the opposite end. This can be detached enabling the shaft to be remove thereby decoupiin the top and front walls 14, 6d which in this the same as decoupiing the first and second lid panels 20t and 20f form each other.

The configuration of the lid structure 18 enables the container 10 to comprise part of a materials handling system. This system would comprise one or more containers 10

Substitute Sheet

(Rule 26) RO/AU and a number of additional front walls/ second lid panels 18d/20f. in this system the second lid panels 2Gf which would constitute the front wall of the containe can be provided with visual indicia representative of a specific type of material contained in or to be received in the container 10. For example the indicia can be the colour of the panel 2 Of, Expanding on this example the colour:

• Blue may be used to signify general and non-hazardous materials requiring no special handling regime

• Yellow may be used to signify used lead acid batteries

« Red may be used to signify used mixed dry cell batteries

• Green may be used to signify oil filters

• Orange may be used to signify used aerosol cans

• Grey may be used to signif liquid waste in this example the remaining walls/panels from which the container 0 is constructed may also be of the same colour. This colour can be for example the same colour used to signify general waste (i.e. in this case blue). Thus a materials handling company may have for example ten containers 10 with blue coloured second lid panels 20t and say twenty additional second lid panels 20t, four each coloured yellow, red, green, orange and gray. The company can simply interchange the second lid panels with one of the colour appropriate for the material to be carried or placed into the container 10.

Also each of the side and top walls ca be provided with a signage holding

arrangement enabling signs to the replaceable attached to the walls. In one simple example this can be two spaced apart rails fixed by rivets to the wall and Into which signs can be slid. in yet a further variation the latch mechanisms 1 12 shown in Ftgures 8a and 8b may be replaced with more sophisticated latch mechanism 200 shown in Figures 12a-19c. Figures 12 and 12b depict component parts of an embodiment of the disclosed latch mechanism 200. The latch mechanism 200 includes a lever 212 which is capable of pivotal movement about a lever axis 214. The lever axis 214 coincides with a central axis of a coupling pin 216. The latch mechanism 200 also includes a latch member 218 which is pivotally coupled about a latch axis 220 to the lever 212. The latch axis 220 coincides with a central axis of a coupling pin 222. As will be explained in greater detail below the latch member 218 can be moved by pivoting the lever 212 about the lever axis 214 so that the latch member 2 8 can engage a catch 224.

Substitute Sheet

(Rule 26) RO/AU The lever 212 and the latc member 2 8 are biased to pivot in the same direction D1 about their respective axes 214 and 220. This bias is provided by way of a lever spring 226 and a latch spring 228. In this particular embodiment the latch mechanism 200 also comprises a bracket 230 which incorporates a base 232, The lever 2 2 is attached to the base 232 by way of the pin 216. The latch member 218 is coupled to the lever .212 by way of the coupling pin 222. The coupling pin 222 has opposit ends that ride in respective slots 234 on opposite side walls 248 of the lever 212. The coupling of the latch 218 to the fever 212 is completed by a screw 238 that passes through a hole 238 in a depending lug 240 of the lever 2 2. The screw 238 also engages a threaded hole 242 formed in the coupling pin 222, Therefore turning of the screw 238 causes the coupling pin 222 to slide along the slots 234.

Looking at the components of the latch mechanism 200 in more detail it will be seen that the lever 212 has an upper plate portion 244 formed with an opening 246. The side walls 248 extend downwardly from opposite edges of the plate 244. The slots 234 are formed in the side walls 248. The side walls 248 include planar projections 250 in which respective holes 252 are formed. The latch member 218 is formed with a transverse bar 254 extending between arm 258. The arms 256 extends side by side and generally parallel to each other. A hole 2:58 is formed near and in-broad of an end of each arm 256 distant the bar 254.

The coupling pin 222 has a central cylindrical portion 260. Extending axiaily from opposite sides of the portion 280 are reduced diameter portions 282. The portions 282 ride in the slots 234. Extending axiaily from the portions 2:82 are respective reduced diameter stubs 264, The stubs 264 extend through the holes 258. In orde to retain the coupling of the pin 222 to the latch member 218 onc the stubs 264 have been passed through the holes 258 their respective fre ends ar pressed outwardly to form flanges 266 of diameter of greater than that of the holes 258.

The bracket 230 is provided with a plurality of holes 270. The holes 270 ca receive fasteners (not shown) for attaching the bracket 230 to an article. The bracket 230 includes or incorporates the base 232. The base 232 is in the form of two upright lugs 272 each of which is provided with a hole 274. The bracket 230 is also provided with an upright lug 278 formed with a hole 278.

Substitute Sheet

(Rule 26) RO/AU ΤΓΪΘ lever 212 is attached to the bracket 230 and in particular the base 232 away of the pin 216 which passes through the holes 250 and 274. During assembly the opposite ends of the pin 216 are flared outwardly to form respective flanges 280. The flanges 280 have a diameter greater than that of the holes 250 and 274. The lug 278 is located so as to pass through the opening 246 (as shown for example in Figures 13a, 14a and 17) when the lever 212 overlies the bracket 230,

The lever spring 226 comprises two coils 282 spaced apart by an integral U-shaped tongue 284. Each coil 282 is also formed within an integral hook arm 286. The route of the lever spring 225 is detailed in Figures 15a, 15b and 17. From these Figures, it will be seen that the coils 282 are located about the pin 216. The tongue 284 lies beneath and presses against an underside of the plate portion 244 of the lever 212. The hook arms 286 hook around the iugs 272. The spring 216 acts to bias the lever 212 in the first direction D1 (shown in Figures 8c and 19c). The direction D1 is a direction toward the bracket 230.

With particular reference to Figures 12a, 16a, 16b and 17, the latch spring 228 is formed with two coils 288 which are spaced apart by an integral link 290. The end of each coil 288 distant the link 290 is provided with a respective hook finger 292, In the assembled latch 200, the coils 288 reside on respective portions 282 of the pin 222, while the fink 290 runs transversely across the lever 212 beneath the side walls 248. The hook fingers 292 hook about the arms 256 of the latch member 218. The latch spring 228 is configured: to bias the latch member 218 to also pivot in the directio D1. By virtue of the aforementioned arrangement, the latch spring 228 acts between the latch member 218 and the lever 212.

Applying a force to pivot the lever 212 in a direction D2 which is opposite the direction D1 will increase the tension in the lever spring 226. However this will have no effect on the tension in the latch spring 228. In this manner th lever spring 226 and latch spring 228 operate independently of each other. Pivoting of the latch member 218 in the direction D2 relative to the lever 212 will increase the tension in the latch spring 228. Due to the relationship between the respective pivot axes 214 and 220, such action is also likely to creat a moment about the axis 214 and provides some increase in tension in th lever spring 226.

The screw 236 can be turned in opposite directions to traverse the pin 222 along the slots 234 thereby allowing th position of the latch member 218 to be varied with

Substitute Sheet

(Rule 26) RO/AU respect to the lever 212. This is also manifested by an adjustment in the distance between the respective pivot axis 2 4 and 220.

Referring back to Figure 12a, the catch 224 comprises a plate 296 which is turned or curled at one end to form a hook 298. A plurality of holes 299 is formed in the plate 298 to receive fasteners (not shown) for fixing the catch 224 to a second article (not shown),

The Figures : 13a- 13c show the latch mechanism 200 in a released or unlatched position, t the released position:

the lever 212 is biased by the lever spring 226 against, and overlies, the bracket 230;

the latch member 218 is biased by latch spring 228 against and overlies the lever 212; and

the lug 276 extends through the opening 248 in the lever 212,

The lever spring 226 and latch spring 228 are preloaded so that when the latch mechanism 200 is in the released position both springs are under tension biasing the lever 212 and the latch member 218 in the direction D1. As a result irrespective of the orientation of the article to which the latch mechanism 200 is attached the latch mechanism 218 bears against the lever 212 and the lever 212 bears against the bracket 230. This prevents the latch arm 218 and/or lever 212 from freely swinging about their respective axes. This is of praciical benefit as neither the lever 212 nor the latch can swing out and potentially be accidentally run into to by a person to cause injury or hits by a piece of equipment and thus damaged or broken. Also in the released position the lever arm 218 is disengaged and spaced from the catch 224. Therefore the respective articles to which the bracket 230 and catch 224 are attached may be moved relative to each other, Figures 14a-14c depict the latch mechanism 200 in the engaged or latched position. In this position:

the latch member 2 8 is engaged with the catch 224, and more particularly the bar 254 is received within the curvature of the hook 298;

the lever 21 is biased by the lever spring 224 against the bracket 300; the lug 278 protrudes through the opening 248 with the hole 278 also exposed above the lever 212,

Substitute Sheet

(Rule 26) RO/AU The latch spring 228 is in its most tensed state and applies a moment to the lever 212 in the direction D2 about its pivot axis 214. However this does not result in the lever 212 pivoting in the directio to away from the bracket 300. In particular the spring 226 is arranged to have a bias which overcomes the moment applied by the latch spring 228 when the latch mechanism 200 is in the latched position. Additionally the effect of the moment applied by the latch spring 228 is reduced by the location of the pivot axis 220 being below the pivot axis 214.

The combination of the lug 276 and the opening 246 form a locking facility enabling the lever 212 to be locked against pivotal movement about its axis 214 at least to the extent that would result in the latch membe 18 disengaging from the catch 224. This is achieved for example by coupling a padlock o other type of secure lock {not shown) to the lug 76 through the hole 78. Figures 18a-18c; and 19a-19c illustrate two sequential intermediate positions of the latch member 200 moving from the released position to the latch position.

Starting with the latch mechanism 200 in the released position {shown in Figures 13a- 13c) a force, for example by a person's thumb, is appiied to the lever 212 causing it to pivot in the direction D2 about its pivot axis 214. This is against the direction of the bias applied by the lever spring 226. The latch member 218 is carried by the lever 212 so as to reach over the catch 224 and i particular the hook 298. From the position shown in Figure 18c the user may either: (a) continue to pivot the lever 212 in the direction D2 so that the bar 254 will be located adjacent the catch 224 and in the vicinity of position PI ; or {b) separately pivot the latch member 218 about its pivot axis 220 away from the lever 212 so that the bar 254 lies adjacent the catch 224 around the position P1. in either case it will be recognised that th latching

mechanism 200 is not at this stage in the engaged position as the bar 254 is spaced from and not received within the hook 298.

In order to effect engagement and place the latching mechanism 200 in the latched position the force applied to the lever 21 is steadily reduced or can be totally refeased while holding the latch member 218 against the catch 228, This will result in a translation of the latch member 218 and in particular the bar 254 toward and into engagement with the hook 298. This position is shown in Figures 19a-19c. If a user has not already released the fever 212 they may now do so and rely on the bias of the lever spring 226 and the over centre actio of the lever mechanism 200 to pivot the

Substitute Sheet

(Rule 26) RO/AU lever 212 in the direction D1 towards the bracket 300. it should also be understood that this pivoting motion has the effect linearly displacing the bar 254, and thus pulling the catch 224, toward the base 232 and bracket 300. The degree of this puil can be adjusted by turning of the screw 236. This adjustment would be normally performed prior to the latching mechanism 200 being moved to the latched position. in use the adjustment may be done by trial and error moving the latch mechanism to the intermediate position shown in Figures 18a-19c and feeling the degree of force required to push the lever arm 212 in the direction D1 so as to lie against the bracket 300 with the lug 278 extending through the opening 246. The degree of adjustment of spacing between the axis 214 and 220 is approximately equal to the length of the slot 234 minus the diameter of the arms 262.

Depending on this adjustment, the lever 212 ma be able to return by action of the lever spring 228 only. However in order to tightly couple the latch arm 218 to the catch 224 it is envisaged that the adjustment will be such that the lever will pivot by actio of the !ever spring 226 alone oniy to a position where is it spaced above the bracket 300. in order for the lever 212 to be placed against the bracket 300 a force will need to be applied to snap the Sever down onto the bracket 300. This also provides the pulling effect described a bove of the catch 224 towa rd s the bracket 300, i order to disengage the iatch mechanism 200 (i.e. move it from the latched position to the released position} the user need only pivot the lever 212 in the direction D2 through an angle sufficient to slide the bar 254 out of the hook 298. At that time the bias of the latch spring 228 will automatically pivot the latch member 218 in the direction D1. The user may simultaneously release the force on the lever 212 which will result in the lever spring 226 pivoting the lever 212 in the direction D1 carrying with it the Hatch member 218, The lever 212 and latch member are thus returned to the released position shown in Figs 13a- 13c.

The latch mechanism 200 may be embodied in other forms. For example the base 232 may be formed integrally with (i e. moulded into or as part of) the various walls 16 much like hinge portions 58 to provide an anchor point for the lever 21 which can be coupled via the coupling pin 214. Similarly, the catch 224 and more specifically the hook 298 can be moulded into other walls 16 of the container 10. in the claims which follow and in the preceding description, except where the context
