Title: CORE TRAY FASTENING SYSTEM

Field of invention [01] The present invention relates to core trays into which drilling samples are received for preservation during conveyance and storage. In particular it relates to a means of fastening one tray to another to stabilise a collection of trays being conveyed, such as from a drilling site to an analytical facility.

Background to the invention [02] A core drill is a geological exploration tool that has an annular drill bit, used for extracting intact from a sample site an elongate sample representative of the strata through which the drill has passed. It is important to maintain the sample intact analysis.

[03] Core trays have been developed with a series of parallel channels sized for receiving core lengths and maintaining their separation and structural integrity during transportation off-site and during periods of subsequent storage pending analysis. As numerous samples tend to be collected at each drilling location, the trays need to be stackable and have facility for enabling clear labelling of the samples.

[04] The following patent publications describe the state of the art:

a. AU2013204184, which proposes a handle arrangement to facilitate manhandling of trays;

b. US application 2010/0018886 Al, which is directed to facilitating removal of the core sample from the tray;

c. AU2013251234, which addresses stacking issues;

d. AU 2013204793, which addresses drainage of fluid accumulating in the tray.

[05] A drawback of currently available core trays not addressed above is in their structural make-up and suitability for secure transportability. The competing drivers of

2016204775 08 Jul 2016 weight, portability, strength and useful life tend to lead to compromises in design and resultant expense. Features for facilitating off-site transfer have largely been ignored.

Objects of the invention [06] It is an object of this invention to address the shortcomings of the prior art and, in doing so, to provide a core tray having means for fastening to another of like construction to inhibit relative movement in transit.

[07] The preceding discussion of the background to the invention is intended to facilitate an understanding of the present invention. However, it should be appreciated that the discussion is not an acknowledgement or admission that any of the material referred to was part of the common general knowledge in Australia or elsewhere as at the priority date of the present application.

[08] Further, and unless the context clearly requires otherwise, throughout the description and the claims, the words 'comprise', 'comprising', and the like are to be construed in an inclusive sense - that is to say, in the sense of including, but not being limited to - as opposed to an exclusive or exhaustive sense - that is to say meaning including this and nothing else.

Summary of invention [09] According to the invention, there is provided: a core tray tethering system for tethering together first and second core trays when located to be in substantially coplanar edgewise abutment, each tray comprising a base having an upper and a lower surface, the base being shaped so that the upper surface defines a plurality of corereceiving channel-like spaces and the lower surface defines spaces between the channels; wherein the system comprises a fastener adapted for engaging with a tethering formation provided on each tray.

[010] According to an aspect of the invention, there is provided a core tray comprising a base having an upper and a lower surface, the base being shaped so that the upper surface defines a plurality of core-receiving channels and the lower surface

2016204775 08 Jul 2016 defines spaces between the channels; and a fastener adapted for fastening the tray to a like tray located to be in substantially coplanar edgewise abutment, against separation.

[Oil] The fastener is so configured such that when either tray is subject to potentially separating force acting substantially in a plane in which both are located to separate one from the other, the fastener resists such separation.

[012] In an embodiment of the invention, the fastener is adapted to engage with an engageable formation on each tray, thereby tethering the trays together.

[013] In a preferred form of the invention, the engageable formation comprises an upwardly extending projection of sufficient height to be operatively engaged by the fastener.

[014] In an embodiment, the projection is configured for engagement with a portion of a like tray stacked upon it.

[015] In a preferred alternative embodiment, the projection is sized to be spaced from an overhanging portion of a like tray when said like tray is stacked above it, so that a space is defined therebetween, the space being sufficient to allow the fastener to be received in operative engagement with the projection. The projection is preferably integrally formed with the tray. The tray is preferably of moulded construction using techniques well known in the art.

[016] In an example, the projection may be generally monolithic of blocky shape. Preferably, the projection has four vertically disposed sides connected at bevelled vertically-disposed corners. In an embodiment, the projection has a generally horizontal groove in a channel-facing side. Preferably, the fastener, while engaging the projection, is configured to engage a like projection on an adjacently located like tray thereby to tether said trays together. As a result of the fastening, relative movement of the tethered trays is restricted.

[017] In a preferred embodiment, the tray has a periphery at which the projection is located.

2016204775 08 Jul 2016 [018] In a still further preferred form of the invention, the tray comprises a peripheral wall connected to and surrounding the base and collectively surrounding the plurality of channels, and wherein the projection is located externally to the rim.

[019] Preferably, the projection extends from a lip extending generally horizontally from the wall. In an embodiment, the lip defines a grip-bar for use in manual lifting of the tray.

[020] The wall may comprise 3 or more sides with the projection being located adjacent a corner defined where two sides meet. When the tray is of rectangular shape, a projection is located adjacent each corner.

[021] In a preferred embodiment, the projection extends to a height lower than that of the rim to define a space for receiving the fastener in operative position. Further preferably, the projection height is substantially lower than the rim height. In this configuration, the projection remains sufficiently high and still accessible for the fastener to be attached, even when a like tray is stacked above it.

[022] In a yet further form of the invention, the fastener is resiliently extensible to be fitted to opposing projections on first and second trays to be fastened together.

[023] In a preferred embodiment, the projections are located on the trays to be adjacent each other when the trays are arranged side by side or end to end.

[024] The fastener preferably comprises a belt. The belt desirably is of a resilient material selected to have predetermined limited extensibility.

[025] Preferably, the belt is elastic, resuming an original shape and size when not in use for possible re-use. Preferably the belt is an endless belt. In an alternative embodiment, the fastener comprises a substantially rigid loop of generally oval shape, or rectangular shape with rounded corners. Preferably the loop is of a thermoplastics substance. In a further embodiment, the fastener of generally oval shape has a discontinuity along one of its major sides. The fastener may also be formed in the shape of oppositely oriented hooks extending from a common shank.

2016204775 08 Jul 2016 [026] In a preferred form of the invention, the base of the tray has a reinforcement structure beneath the lower surface extending between adjacent first and second channels and comprising a pair of intersecting first and second planar elements each of which subtends an acute angle with a longitudinal axis of each channel.

[027] In a preferred form of the invention, the tray comprises a spacer element extending between said first and second channels in a direction substantially orthogonal to respective longitudinal axes of the channels.

[028] In a further preferred form of the invention, the reinforcing structure comprises further pairs of intersecting planar elements such that the structure extends from a first end of the tray to a second, distal end between said first and second channels.

[029] In a preferred embodiment, the intersecting first and second elements intersect to define a lattice.

[030] The lattice structure is further preferably bound between first and second spacer elements extending between the channels in a direction orthogonal to said axes.

[031] Further preferably, the core tray comprises at least three channels, wherein the reinforcing element is co-planar with a second reinforcing element of like type and orientation extending between the second and the third channel.

[032] According to a further aspect of the invention, a method of stabilising two or more core trays of like design during transport, the method comprising providing first and second core trays of like design adapted for receiving a fastener in operative orientation for fastening them together against independent movement; and a fastener adapted for fastening the first tray to the second tray; positioning the first tray alongside the second tray to be in substantially coplanar edgewise abutment, and applying the fastener to the first and the second trays in separation-preventing manner, whereby the trays resist separation under application of lateral force.

[033] The method extends to a method of relocating first and second trays including the step of fastening together first and second core trays as stated above and

2016204775 08 Jul 2016 applying force to the first tray to cause it to move in a desired lateral direction, in tandem with the second tray, from a first location to a second.

[034] Still further according to the invention, there is provided a core tray comprising a base having an upper and a lower surface, the base being shaped so that the upper surface defines a plurality of core-receiving channels and the lower surface defines spaces between the channels; an upwardly extending peripheral rim collectively surrounding the plurality of channels; and a projection located externally to the rim and extending upwardly from the upper surface to a height not exceeding that of the rim.

[035] Preferably the projection is of blocky shape.

[036] Further preferably, the projection is spaced from the rim by a gap sufficiently wide to receive a fastener adapted to pass through the gap and a gap on an adjoining tray whereby the trays are tethered to each other.

[037] In a preferred form of the invention of this aspect, the tray has a skirt surrounding the base and having dimensions adapting it for fitting within a periphery defined by the rim of a like tray when placed over it. The skirt may have a concave lower surface and defines a grip bar for use in manual lifting.

Brief description of drawings [038] In order that the invention may be readily understood, and put into practical effect, reference will now be made to the accompanying figures. Thus:

Figure 5 provides a front view of stacked trays from Figure 1.

Figure 6 illustrates the fastening system of the invention applied to two stacks of trays of the kind illustrated in Figure 5.

Figure 7 is a schematic side view of stacked trays of an alternative embodiment in a connected tandem arrangement.

Detailed description of an embodiment of the invention [039] Referring to figure 1, showing a preferred embodiment of this invention in perspective view, a core tray is generally denoted by the number 10. It is of substantially rigid construction, made of a high density polyethylene (HDPE), injection moulded to shape, as is well known in the art, but may be made of any other suitable impact resistant substance, including in particular metals and other plastics, for example ABS. The tray is generally rectangular, defined by a base 12 bounded by pairs of opposed longer sides 14, 14' and opposed shorter end walls 16,16'.

[040] In this embodiment, the tray has four core-receiving channels 18 formed in the upper surface 20 of the base. The channels extend longitudinally along the length of the core tray and are closed at their opposite ends by end walls 16, 16'. The channels have side walls 22 extending upward so that proximate walls of adjacent channels are separated by an interposed joining strip 24 to form an intervening dividing wall, as shown in Figure 2.

[041] The base also has an underside 26, which will be described with reference to

Figure 3.

[042] The opposing side walls 22 of each channel slope inwardly and curve further at rounded sections 28 to meet a flat bottomed channel base section 30. It is found that allowing the walls to taper inwardly allows a greater range of core sample diameters and irregularities to be stably supported in their respective channels.

[043] It will be appreciated that the channels may be defined by differently shaped profiles and still fall within the scope of the claims to this invention. The tray dimensions are able to be varied for manufacture to meet particular field requirements.

2016204775 08 Jul 2016 [044] With reference to figure 3, the underside of tray 10 is shown with like numbering denoting like parts and features. Reinforcing elements of two kinds are illustrated. These help keep the channel side walls 22 from buckling, especially in an outward direction that would increase the channel size and available receiving space for a core sample. Such an increase would lead to sample being less securely held and increase the likelihood of its shifting during transit and the risk of its breaking and disintegrating.

[045] The first kind of reinforcing element 32 is disposed orthogonally to the longitudinal axes of the channels between which it extends and the second kind 34 is disposed non-orthogonally between the walls of adjacent channels.

[046] The first kind of element serves as a spacer between opposing walls of adjacent channels such as 18a and 18b. The second kind 34 is located to extend diagonally between opposing channel walls 22 and from one spacer 32 to the next, for example from 32a to 32b.

[047] To facilitate stacking of the tray on top of another of the same design, side walls

14, 14' extend vertically downwardly to define and end in a downwardly-projecting skirt 60. The skirt extends below each of the end and side walls 16, 16', 14, 14' so that it surrounds channels 18 collectively. When a first tray 10a is placed upon a like tray 10b, skirt 60 of tray 10a fits within the perimeter defined by upper rim 80 of tray 10b below it. The skirt fits within the rim to the extent permitted by the sloping edge of brace portion 46. This enables a space 82 to be maintained between the upstanding fastener-receiving projection 54b of the lower tray and the overhanging lip 38a of the upper tray. Space 82 enables a flexible, ring-like fastener 70 to be placed over and around projection 54b in a taut manner.

[048] These features operate to allow an upwardly projecting formation 54b from the extending lip of a lower-placed tray in a stack to remain available for engagement by the fastener. These correspondingly positioned formations are provided at each corner of the tray to provide four points of engagement and hence increased stability of a stack of trays against relative movement, such as during transit from drilling site to analytical facility.

[049] When the projections are so aligned, a fastener may be applied to connect them and stop them from uncontrolled separation. In a first embodiment, the fastener takes the form of an O-ring of selected limited extensibility, but with tensile strength sufficient to prevent uncontrolled separation of the leading and following trays. This embodiment is

2016204775 08 Jul 2016 illustrated in Figure 5. The fastener is of tautness and an operative length substantially sufficient to keep the trays in abutment when aligned.

[050] Referring to Figure 6, two stacks of trays 100, 110 are shown placed upon a pallet 116 ready for transportation. A fastener band 170 is shown passing over and around projections 154A and 154B on the bottom trays of each stack.

[051] In Figure 7, a second embodiment of a tray in the invention is illustrated. In this case, to facilitate stacking of one tray on top of another of the same design, there is provided a cavity 56 below a lip 38 that allows an upwardly projecting formation 54A, 54B from the extending lip of the tray on which it is stacked, to remain available for engagement by the fastener. These correspondingly positioned formations are provided at each corner of the tray to provide four points of engagement and hence increased stability of a stack of trays against relative movement, such as during transit from drilling site to analytical facility.

[052] In other embodiments, fewer projections may be provided. Alternatively, additional projections may be provided. Also, their positioning may be varied without departing from the scope of this invention. In another exemplary embodiment, each tray has but two such projections, these being positioned on the longitudinal centre line (or axis), as that the projections of leading and following trays are longitudinally aligned when placed end to end.

[053] Also in Figure 7, there are shown in cut-away side elevation two pairs of trays 62, and 66, 68, arranged end to end in a stack of two layers with their respective pairs of short ends 72, 74 in close abutment. Respective projections 54a, 54b from the lower trays extend above the level of the tray rim for being located in receiving cavities 56a, 56b in the two respective upper trays.

[054] To facilitate stack transport - for example on an unpowered roller conveyor having rotating rollers 76 - there is provided an endless belt 70 of selectively limited extensibility to hook around the projections 54A and 54B of the upper pair of trays 62, 64.

Further trays may be similarly added to form a train of trays that are able to be pushed together from one end of the conveyor to the other.

2016204775 08 Jul 2016 [055] In another application, being that of facilitating transport of a stack of trays - for example trays on a pallet being moved by a forklift - there is provided a substantially rigid band to hook around the projections 54A and 54B of the upper pair of trays 62, 64. By using the endless band in this manner, the risk of a tray moving independently whilst the pallet is being moved from one location to another is minimised. The result is a better stabilised stack of trays. A preferred material of construction of the belt or band is hardened rubber. The belt may be provided as a rubber O-ring or as a plastic band or metal belt, for example steel.

[056] The elasticity of the belt is limited to an extension coefficient of less than 2, preferably less than 1.3. Within these limits, adjacent trays are suitably closely retained when being moved on a pallet in a stack.

[057] In an alternative embodiment, the fastener is a cap defining an open internal space shaped to receive projections concurrently from two trays to be joined. In an alternative form, the space is divided in two cavities, each shaped for receiving a projection from respective trays to be fastened. Preferably the cap is of moulded construction, configured to fit snugly over each projection. The cap may be of substantially rigid construction, for example of HDPE. However, it may alternatively be made of an elastic material such as a rubber natural or synthetic.

[058] The fastener may be provided already attached to the tray, for example to the front end of the tray bearing the labelling space 52 in figure 1, ready for attachment in a tandem arrangement to the rear of a leading tray. The leading tray would similarly have a fastener to fit around a projection on a tray before it. The rear end of the tray may also be equipped with a fastener in like fashion, this time to attach to the tray following it. When used in stabilising a number of trays placed side by side, for example for transporting on a pallet, adjacent trays are tethered using the fastener. When considered desirable, trays may be simultaneously tethered side by side and end to end. A single loop, manufactured to be large enough or suitably resiliently extensible, may be fitted around the projections at the corners of four abutting trays.

[059] In embodiments, the projection is adapted to be engaged by the fastener.

For example, the projection may be generally monolithic, of blocky shape having four vertically disposed sides. Preferably the sides are connected at bevelled vertically-disposed

2016204775 08 Jul 2016 corners. In an embodiment, the projection has a generally horizontal groove in a channelfacing side. The groove is sized to receive a ring or belt-configured fastener with the groove inhibiting upward slippage of the belt out of the groove and over the summit of the projection.

[060] In another embodiment, the projection, such as that labelled 54 in the figures, has an aperture formed in its summit surface and a connector element in the shape of an upturned letter U, or a letter M and having distally downward extending legs, has one leg inserted the engage through the aperture. The other leg of the connector is then inserted in a like aperture of a tray to be fastened in tandem. The connector is quickly removable to release the trays when needed, such as at the storage or processing destination after transport.

[061] Reverting to figures 1, 3 and 4, the spacer elements of both kinds described above extend from base level 30 to the top of channel side walls 22, meeting with the underside of inter-channel joining strip 24. By extending at base level from side to side of adjacent channels and continuing up the opposed channel sides to the top, continuous reinforcement is provided to the channel walls where meeting the plane ofthe reinforcing elements, irrespective of type.

[062] The spacer elements 32 are shown transversely aligned from channel to channel.

They are also transversely aligned with exterior reinforcing elements 36 extending from external side wall 14 to the inside surface of an overhanging peripheral lip 38 (also shown in Figure 2). Lip 38 provides a formation under which personnel may place their fingers when lifting the tray. This formation extends around the entire periphery of the tray at a uniform level in relation to the rim of walls 14 and 16 defining a grip-bar which can quickly and easily be found by personnel without being unduly distracted in seeking it on a moving surface such as a conveyor belt.

[063] Reinforcement elements 34 define a zig-zag pattern 40 from one end of the tray to the other, being formed head to tail. The central gap 42 defined between the second and third of the four channels has overlapping zig-zag patterns that define a lattice extending diagonally across the rectangular space defined between sequential orthogonal spacer

2016204775 08 Jul 2016 elements 32c, 32d. In the embodiment being exemplified here, the criss-crossing elements 34 have their central crossover at region 58.

[064] With further reference to Figure 4, the outer side walls 14, 14' are reduced in regard to flexion potential by means of bracing elements 46, which are connected to the wall and overhanging lip 38, to extend between them. Bracing elements 46 are in this embodiment applied at intervals that align with transverse spacer elements 32. Similar bracing elements are installed between lip 38 and end walls 16,16' and assist in preserving the structural integrity of the tray when others are stacked on it, or when it is being pulled or pushed with another, as described above.

[065] An indicium 50 is applied at one end of the tray to differentiate it from the other end so as to indicate to drilling personnel the desired orientation of the samples when being placed in the tray and to a core analyst which end of the core was obtained at the shallower drilling depth.

[066] The tray further has moulded flat areas 52, suitable for holding an identification tag or other means suitable for identifying the tray contents from both end and side of the tray.

[067] These embodiments merely illustrate particular examples of the core tray fastening system of the invention providing for the lowering of the risk of destruction of cores during transportation and storage. With the insight gained from this disclosure, the person skilled in the art is well placed to discern further embodiments by means of which to put the claimed invention into practice.
