SPECIFIC DESCRIPTION

[0080] In an attempt to reduce misplaced or lost removable shelves for rigid containers for the transportation of dry goods, the inventors have appreciated that it may be desirable to provide a removable shelf 1, 2 with one or more shelf locators 10,11 as shown in FIG. 1. FIG. 1 shows a removable shelf 1, 2 for rigid containers for dry goods. The described removable shelf 1, 2 is essentially a continuous panel 9 which may be made from one or more rigid pieces of plastics. The removable shelf 1, 2 may thus come as a single or integral panel 9 or may be assembled and/or assemblable from a number of subcomponents. It will be appreciated that the removable shelf 1, 2 may be manufactured according to different methods or techniques and may be made of or include parts which are not made of plastics, although for the present purposes and applications plastics are advantageous since they may readily provide light weight and suitable rigidity, as known in the arts.

[0081] The removable shelf 1, 2 comprises at least one shelf locator 10, 11. Each shelf locator 10, 11 or the shelf locators 10, 11 collectively, are usable by a user after removing the removable shelf 1, 2 from the container to prevent the removable shelf 1, 2 from becoming misplaced or lost. To do so, the user can attach the removable shelf 1 to the container, as will be described further below, via the shelf locator(s) 10, 11. The removable shelf 1, 2 can thus be easily located. A removable shelf 1, 2 may comprise two and only two shelf locators 10, 11 which may be provided on a front face 3 of the shelf 1. However, a different number of shelf locators would likewise be possible, as an example just one. In the removable shelves 1, 2 described herein, for example, there are actually provided four shelf locators 10, 11, 12, 13 in total, on each removable shelf 1, 2in the form of two front shelf locators 10, 11 as shown in FIG. 1, provided on the front face 3 of the shelf 1, 2 and two rear shelf locators 12, 13 provided on a rear shelf face 3, which are not shown in FIG. 1 but can be seen in FIGS. 3 and 4. The importance of the rear shelf locators 12, 13 is that a further removable shelf 1, 2 may then be attached to any removable shelf 1, 2. Before describing further the removable shelf 1, the shelf locators 10, 11 and the containers, a few definitions which will help to describe particularly the removable shelf 1, 2 will now be introduced.

[0082] The removable shelf 1, 2 comprises a pair of opposed faces 3 (only one being shown in FIG. 1) one of which, in use (as an upper face), provides support for goods (not shown).

[0083] The faces 3 are surrounded by an edge 8, which delimits the removable shelf 1, 2. FIG. 1 shows a generally rectangular shelf shape, but other shapes are in principle possible.

[0084] Also, each removable shelf 1, 2 may be provided as a complete shelf, or a complete shelf may be made up of two or more smaller shelves that together may provide the required supporting surface. The edge 8 surrounds the rectangular removable shelf 1 on each of its four sides 4. Each shelf face 3, accordingly also has corresponding rectangular face sides 4. In the described removable shelf 1, 2 the shelf locators 10, 11, 12, 13 are provided at opposed ends 6 of the shelf 1, near adjacent corners 5 of the shelf 1 and close to the edge 8 and one of the sides 4 of the shelf 1, 2, as shown in FIG. 1. It is possible to define a local, notional system of coordinates x-y on the removable shelf 1, 2 or on any of its faces 3, as also shown in FIG. 1. The removable shelf 1, 2 has two short sides 4 that extend along the x axis and two long sides 4 that extend along the y axis. The z axis (not shown in FIG. 1, but see FIG. 8) is therefore accordingly designated as an out-of-plane, orthogonal axis with respect to the notional plane x-y defined by the shelf 1, 2 or any of the shelf faces 3.

[0085] Returning now to the operation of the removable shelves 1, 2 described herein, the removable shelves 1, 2 can each 1 advantageously be removably attached to a container wall 101, optionally via another shelf 2, i.e. an intermediate shelf 2, already attached to the container wall 101, so that the removable shelf 1 will not be misplaced in relation to the container 100. It will be understood that the removable shelves 1, 2 described herein can be attached one at a time, or simultaneously in groups of pre-attached two or more removable shelves 1, 2.

[0086] FIG. 2 shows a rigid container 100 for the transportation of dry goods. Before the shape and function of the shelf locators 10, 11, 12, 13 is described further, the basic topography of the rigid container 100 will be described. The rigid container 100 defines an enclosed space 105 in which goods to be transported can be stored. The enclosed space 105 is delimited laterally by one or more container walls 101, at the bottom by a container base 104, and at the top by a removable container cap or lid 107, which may be foldable in halves longitudinally, as also shown in FIG. 2 to facilitate access to the goods. The front wall 101 incorporates an openable front door 109, which may be opened also to facilitate access to the goods (or any shelves provided inside the container 100, which support these goods). One of the side walls 101 incorporates an openable side door 110, which can be used similarly to the front door 109. One or more removable shelves 1, 2 as described herein can be disposed within the container 100 so as to divide up the enclosed space 105 in two or more compartments 106 respectively, and this will now be better described in connection with FIGS. 3 to 5.

[0087] FIGS. 3 to 5 show the container of FIG. 2 with one removable shelf 1 being lowered in position inside the container 100 to support the goods. The removable shelf 1 is rested on appropriate protrusions (not described herein) provided internally, along the vertical sides of the container 100, via shelf rests 15 (shown in FIG. 1) disposed on the four corners 5 of the removable shelf 1. This operation is greatly facilitated, as can be imagined, by the provision on the shelf 1 of one or more handles 14 (also shown in FIG. 1). There is another removable shelf 2 shown in FIGS. 3 to 5, and this second removable shelf is attached face-to-face to the rear wall 101 of the container 100 via two of its shelf locators 10, 11 and two corresponding and complementary shelf locators 12, 13 provided on a rear wall 101 of the container 100. This removable shelf 2 also has additional shelf locators 12, 13, which may be similar or the same with respect to the shelf locators 12, 13 provided on the container rear wall 101, which shelf locators 12, 13 are provided on the shelf rear face 3 for receiving the shelf locators 10, 11 of the removable shelf 1 now placed inside the container 100, when the removable shelf 1 will no longer be needed for the transportation of the goods, but will be attached to and stored in the container 100. Vice versa, the now attached removable shelf 2 could be detached from its location on the rear wall 101 of the container 100 and be deployed as an additional shelf 2 inside the container 100, so as to divide the enclosed space 105 not in just two but three compartments 106 for transporting the goods.

[0088] It will now be appreciated that the front shelf locators 10, 11 shown in FIGS. 1 and 3 to 5 are male shelf locators 10, 11 adapted to be received in corresponding female shelf locators 12, 13 provided on an edge of the container wall 101, or on the edge 8 of the intermediate shelf 2 attached to the container wall 101. Also, the edge 8 of the shelves 1, 2 close to the shelf locators 10, 11 is an upper edge of the shelf 1, 2, when the shelf 1, 2 is vertically attached to the container wall 101, face-to-face, as shown in FIGS. 3 to 5. However, these configurations are not mandatory.

[0089] The one or more male shelf locators 10, 11 could for example be replaced by one or more female shelf locators 12, 13 on one of the shelf faces 3, and vice versa the one or more female shelf locators 12, 13 on the other face 3 of the shelf 1, 2 or on the container wall 101 could for example be replaced by one or more corresponding male shelf locators 10, 11, so long as the shelf locator(s) 10, 11, 12, 13 are collectively usable to attach (in the particular case of the described shelf 1, 2, attach by hanging) the shelf 1, 2 to the container wall 101 or to one or more intermediate shelves already hung to said container wall 101. It is therefore important that the shelf locator(s) 10, 11, 12, 13 are positioned and shaped to achieve this outcome, independently of their specific conformation and x-y position on the shelf 1, 2.

[0090] It is also similarly not mandatory that the shelf locator(s) 10, 11, 12, 13 be disposed close to the upper side 4 or edge 8 of the shelf 1, 2, in the configuration where the shelf 1, 2 is vertically attached face-to-face to the rear wall 101 of the container 100; the shelf locator(s) 10, 11, 12, 13 could otherwise be disposed close to a bottom edge or side of the shelf 1, 2, or laterally. It is however important that the male shelf locator(s) 10, 11 and female shelf locator(s) 12, 13 be disposed in spatially corresponding positions 7 on the x-y nominal plane of the removable shelves 1, 2, such that the male and female shelf locators 10, 11, 12, 13 may form, in use, pairs of engaged male-female shelf locators 10, 12; 11, 13 for attaching the panels 9 as desired on the containers 100. Such positions are shown in FIG. 4, for example.

[0091] The advantages brought forward by providing shelf locators 10, 11, 12, 13 as described herein resonate with the provision of a foldable container 100. With a foldable container 100, at least one of the container walls 101 is folded so that the container 100 can be configured into a more compact form for transportation back to a service centre, together with any attached removable shelves 1, 2. Any removable shelves 1, 2 can therefore be neatly stored away in the folded container 100. At the service centre, the use cycle of the container 100 may start again: the containers 100 would first be reconditioned and then shipped to a place of use, where they would be erected and loaded with the goods to be transported. The removable shelves 1, 2 at this moment will still be stacked inside the container 100 but will be ready to be installed in the enclosed space 105 when the container is prepared for transporting the goods.

[0092] In principle, any manner of removably attaching the shelf face-to-face to the container wall or to an intermediate shelf attached to the container wall may be considered. Further, multiple shelves could alternatively be attached to multiple container walls, and these multiple container walls may all be individually collapsible. An advantageous way of removably attaching the shelf face-to-face against the container wall or to another shelf is by simply hanging the shelf. Alternative to the designs described herein, therefore, it will be appreciated that the shelf locators may each be provided in the form of a hanger or a hook. In such cases, the shelves 1, 2 may be directly hung to the container wall 101, or to any intermediate shelves, internally or externally, without the need for corresponding shelf locators, such as the female shelf locators 12, 13 described herein.

[0093] With reference now to FIGS. 6-10, the at least one male shelf locator 10, 11 is provided, in the described shelves 1, 2, generally in the form of a pin 20, 21 (best shown in FIGS. 6, 9 and 10). The at least one female shelf locator 12, 13 is instead provided generally in the form of a slot 22, 23, which in shape is at least to some extent complementary to that of the pin 20, 21 so that the pin 20, 21 can be straightforwardly and intuitively received in the slot 20, 21, so that the shelves 1, 2 can as a consequence be attached as intended.

[0094] Each pin 20, 21 comprises an enlarged head portion 24 and each complementary slot 22, 23 comprises an opening in the form of a mouth 26, that opens on the edge 8 of the shelf 1, 2, (or of the container wall 101, in case this shelf locator 12, 13 is provided thereon). This mouth or opening 26 is adapted to receive at least the enlarged head portion 24 of the pin 20, 21 but may otherwise receive all of the pin 20, 21. The mouth 26 enables attachment of the removable shelf 1, 2 by the user engaging each pin 20, 21 with the respective slot 22, 23 and then sliding the pin 20, 21 in the x direction shown by the arrows in FIGS. 6 and 7. As shown in FIG. 9, the enlarged head portion 24 of the pin 20, 21 is a distance 25 from the face 3 of the shelf 1, 2 on which this shelf locator 10, 11 is provided. A narrow or stem pin portion 32 joins the enlarged pin head 24 and the face 3 of the shelf 1, 2. A user is accordingly able to easily identify the shelf locators 10, 11, 12, 13, 20, 21, 22, 23 both on the shelf and/or the container wall, or intermediate shelf attached to the container wall, and to use them in the intended manner. Further, the enlarged head portion 24 of the pin 20, 21 prevents the removable shelf 1, 2 from becoming easily or involuntarily detached or disassembled, once the shelf 1, 2 has been attached in place as intended. It will not be possible to detach the shelf 1, 2 by pulling the shelf 1, 2 in the z direction shown in FIG. 8. To detach any of the shelves 1, 2 shown for example in FIG. 7, the user will need to slide one shelf 1, 2 at a time, or both shelves 1, 2 together along the x axis, in a direction which is reverse to that of the arrows shown.

[0095] To put it in other words, the pin 20, 21 and the corresponding slot 22, 23 are adapted to define a dovetail coupling 102 when the pin 20, 21 is received in the slot 22, 23. This coupling is best identified by FIG. 8. The coupling also has a suitable level of clearance 103 to facilitate insertion and removal of the pin 20, 21 from the corresponding slot 22, 23.

[0096] Alternatively, the pin could have had a cylindrical shape and the slot the shape of a correspondingly cylindrical cavity and the shelf could have been placed in the intended position by translation and coupling along the z axis. An alternative manner of retention could have been devised, for example in the form of an interference fitting between the pin and the slot, but this would have been a less preferred solution.

[0097] Returning to the dovetail coupling 102 described herein, it will be noticed that each pin 20, 21 has a generally T-shaped cross section 27, as best seen in FIG. 9. Each pin 20, 21 has a corresponding pin width 30 and pin height 31. Other shapes would, however, have been possible (although they may have been less preferred). For example, the pin 20, 21 (and with it, the corresponding slots 22, 23) could have had a generally trapezoidal shape. All the dimensions quoted in FIGS. 9 and 10 are in millimetres (mm). For example, with reference to FIG. 10, it can be seen that that each pin 20 has a length 28 along the x axis equal to 55 mm. The pin tapers in this direction from about half-way down. This makes insertion of the pin 20 into the corresponding slot 22 easier. The length 28 of the pin 20 in the x direction is important in that, together with the corresponding length 29 of the slot 22 (this can be seen in FIGS. 4 and 11) determines the exact position of attachment of the shelf 1, 2 relative to the container wall 101, or in relation to any intermediate shelves, along the x axis. It may be desirable for the shelves 1, 2, for maximum compactness to have flush or substantially flush edges 8 in the attached configuration. The same consideration applies in relation to the edge of the container wall 101. The pins 20, 21 and slots 22, 23 extend linearly in the x direction, and this further facilitates operation of the removable shelves 1, 2 in that attachment or connection can then be achieved with a single, straightforward movement, after each pin 20, 21 is located in place on the mouth 26 of the slots 22, 23. So that the pins 20, 21 may be sufficiently visible and structurally capable of supporting any forces likely to act on them (not only during attachment, but also during transport, for example), the length of the pin 29 is greater than its transversal width 30 or height 31, as also shown in FIG. 9.

[0098] The containers 100 described herein are fully collapsible, as shown by FIGS. 11, 12 and 13. With fully collapsible, we meant that the containers 100 described herein can be fully folded on their base 104, as shown in FIG. 14. The cap or lid 107 can then be placed on the collapsed or folded container as shown in FIG. 13, for example. In FIG. 11, only one removable shelf 2 is stored inside the folded container 100. However, FIG. 12 demonstrates that two or more shelves 1, 2 may be stored in a stacked configuration inside the folded container 100. An interesting feature arises from the fact that the lid or cap 107 will take a different position vertically, on the folded container 100, depending on the number of removable shelves 1, 2 stored and stacked inside the folded container 100. This can be used to provide visual information to a user as regards the number of removable shelves 1, 2 stacked inside the folded container 100. FIG. 14-5 shows a set of markings 108 provided on the base 104 of the container 100. The markings 108 are disposed such that a curtain 111 that at least partially surrounds the lid 107 will cover one, more or all of the markings 108 such that any visible markings 108 will correspond to the number of shelves 1, 2 stored in the folded container 100.

[0099] FIG. 14, and particularly FIGS. 14-1 to 14-4, illustrate schematically a method of preparing for reverse logistics a foldable rigid container 100 comprising one or more removable shelves 1, 2 as described herein, each comprising at least one shelf locator 10, 11, 12, 13 as described herein. The container 100 is folded, in this example, by folding in turn the side walls (FIGS. 14-1 an 14-2) one on the other, and both over the base 104 of the container 100, then by folding the front and back walls over said side walls, as shown in FIGS. 14-3 an 14-4. All the walls are hinged, but the details of these hinges (as well as the hinge of the lid 107) are not within the scope of the present specification.

[0100] Alternatively, the walls 101 may be collapsible in different fashion, for example by removing each of the walls 101 or all of the walls collectively altogether from the base 104 of the container 100 and lying them flat over this base 104. Using the at least one shelf locator 10, 11, 12, 13 as described herein, although not visible in FIG. 14 the user has attached at least one removable shelf 1, 2 face-to-face to at least one of said walls 101 of the container 101, or to an intermediate shelf as described herein. The removable shelf 1, 2 is then folded over the base 104 alongside the respective side wall 101 of the container 100.

[0101] FIG. 15 exemplifies a method of dismantling a foldable container 100 having one or more removable shelves 1, 2 similar to those described herein, and in addition shows (FIG. 15-8) a first step for preparing the foldable rigid container 100 for transporting dry goods. The container has two removable shelves 1, 2 as described herein, each comprising at least one shelf locator 10, 11, 12, 13 as described herein, via which shelf locator(s) said one or more removable shelves 1, 2 can be attached face-to-face to at least one wall 101 of the container 100, or to an intermediate removable shelf attached to said wall 101.

[0102] In FIG. 15-1, the user, having previously removed the lid 107 from the container 100, and opened the front door 109 of the container, provides to remove a removable shelf 1 from within the container 100. In FIGS. 15-2 and 15-3, operating first on one of the shelf locators 10, and then on the other 11, the user attaches the removable shelf 1 to the rear wall 101 of the container, as previously described. Then, in FIG. 15-4, the user proceeds to fold a first side wall 101 of the container 100, similar to the step in FIG. 14-1. Successively, the container 100 is folded flat, with the removable shelf 1 being visible on top of the folded side walls 101 (FIG. 15-5). At this point, the lid 107 is put back on the folded container 100 (FIG. 15-6), and the considerations made above in connection with FIG. 14-5 likewise apply to this step and the next step (FIG. 15-6) where the folded container 100 is shown in its configuration ready to be transported back to a service centre for restarting a transportation cycle (although the markings are not visible in FIG. 15). Imagining that the folded container 100 has now been transported back to the service centre, and has been reconditioned, if required, or otherwise serviced, the container 100 can now be newly erected as shown in FIG. 15-8, wherein the user now detaches the removable shelf 1, 2 from the container wall 101 so that he or she can then proceed to reinstall the removable shelf 1, 2 in position within the container 100 for supporting goods to be loaded onto the shelf.
