DETAILED DESCRIPTION

(27) There will now be described, by way of example only, the best mode contemplated by the inventor for carrying out the present invention. In the following description, numerous specific details are set out in order to provide a complete understanding to the present invention. It will be apparent to those skilled in the art, that the present invention may be put into practice with variations of the specific.

(28) FIG. 4 shows an example of a pallet 20 supporting a load 42; the load placed upon the pallet so that the outer extent of the load corresponds with the area of the pallet base. Whilst the pallet 20 is not shown in any great detail, it is manufactured from wood and is a four-way entry pallet, wherein the tines of a fork lift or similar tined lifting device can insert its tines through gaps typically having a lower-most height of 100-120 mm, but this will vary, dependent upon the material of manufacture of the pallet and the load to be supported. FIG. 5A shows a cardboard cylindrical sleeve 51 in accordance with a component of the invention. The cardboard, comprises four walls 55 and is dimensioned such that it can be placed about a pallet base when placed upon a ground surface or other support surface and comprises a generally cylindrical member, and can simply be manufactured, for example, from a single sheet of cardboard, glued or otherwise attached along a mutually overlapping portion, conveniently being a corner of a rectangular cylinder. Equally, the sleeve could comprise an elongate rectangular sheet, with fold lines to act as hinges or specific hinges between side walls, with two ends that can be removably fastened, whereby to enable a sleeve to be assembled or dissembled. This particular embodiment shows a first ground aperture portion 52 defined between a ground contact skid or foot portion 54 (collectively the feet of the assembly). The other side corresponds, converting the 4-way entry pallet of FIG. 4 into a two-way entry pallet assembly. In use, the tines of a fork-lift truck are introduced into the region defined by the aperture, which is conveniently at least 140 mm high, whereby when a palletized load is present within the transport/storage assembly and it is desired to move the palletized load, then the tines of the lifting device are inserted so that they pass through the assembly and extend to the other side. Initially the tines contact the underside of the pallet and lift the pallet and then engage the underside of the walls defining the top of the aperture.

(29) In FIG. 5A, optional apertures 53, are placed within the walls 55, to assist in placement of the sleeve about a pallet. It has been found that by the provision of support member inserts about the downwardly directing edges of the apertures for the tines in the sidewall, the lower surface is sufficiently strengthened to accept repeated use of tines associated with forklift trucks and other types of tined lifting apparatus. Applicants have therefore been able to reduce the number of components in a transport and storage system to a foldable sidewall and cover therefor.

(30) In the manufacture of development products, Tri-Wall Europe Limited corrugated cardboard products have been utilized, who produce high performance corrugated board specifically developed for heavy-duty packaging applications. There are several standard Tri-Wall board grades, and widths ranging from 3 mm, to 15 mm, with differentiators including the weight of the papers and the flute profiles, as well as the number of corrugations, the use of wet strength resins and wet strength adhesives to give good-excellent performance in moist or humid conditions. It is also possible to coat the board to provide further moisture protection, for example.

(31) In use, the sidewalls can be employed to surround loads in their own right or, for example, loads placed upon pallets; subsequently a cover can be placed upon the sidewalls, conveniently engaging with the upstanding edges or lips of the sidewall, to provide a secure enclosure for the load. Therefore, the load is shielded from dust and other interference; the load cannot be tampered with easily and further loads can be placed upon the cover. In tests, a widely available (and therefore available at an economical cost) 15 mm Tri-Wall 1250 grade board has been used for the sleeve, with respect to a container suitable to surround a Euro Pallethaving dimensions of 1250 mm1000 mm. This has been found to provide sufficient strength to support loads approaching 1000 Kg from a cover, but a safe working limit upon the covers would be 300-600 Kg. Obviously different grades of cardboard will provide different working weigh limits. Using standard 15 mm thick corrugated cardboard sidewalls, for example, as a euro-pallet enclosure, it has been determined that a weight of 1000 Kg can be supportedmeaning, that a working limit of 300-600 Kg can be defined, taking into account potential deterioration over time and possible incompetence of handling in use. Moreover, it has been found that standard height loads can be safely stacked up to three high, with health and safety issues necessitating a limit in view of possible overloading in use. Notwithstanding this, the skilled man will realize that a greater number of half-height transport/storage assemblies can be stacked.

(32) FIG. 5B shows a sleeve in accordance with the inventionwhen assembled and showing only one side 55 of the assembly, with a first lid 56, having an L-section member 57: FIG. 5C shows a side view of a second type of top 59, the differences between the two lids can be simply determined with reference to respective plan views as shown in FIGS. 5D and 5E, and, in particular, FIG. 5F. The L-section member can be formed as an extruded paper corner-board, which products are available from many paper and cardboard suppliersfor example, they are made by companies such as ITW (under their ANGLEBOARD brand). Specifically, FIG. 5C shows a lid wherein L-section member 57 lies external to the upper wall section 55 shown in the figure, but only extends across half the distance of the cover panel, from the left hand side to the center of the side panel. FIG. 5D shows how the L-section member lies from a plan view. In FIG. 5D, FIG. 5F lid 59 has two L-section members, 57, 58, which lie on the perimeter and surround the upper lip edges of the sidewalls of the container when placed on the lid. The L-section member conveniently comprises an extruded paper corner-board, with section dimensions of 35 mm or 45 mm and is readily available as discussed with reference to the aperture reinforcement; again, the L-section member can be attached using hot-melt glues, for example, whilst other types of materials can be used to manufacture such L-section members, including plastics, especially extruded plastics.

(33) FIG. 5F shows how the upper part of the lid 56 is formed, using three layers 72, 73, 74 of sheet material. Conveniently, the material is corrugated cardboard; conveniently, the directions of the corrugations are perpendicular as between adjacent layers. For example, the cover can be manufactured from bonded layers of triple-layer (corrugated) corrugated cardboard, with the orientation of the two layers of cardboard being orthogonal with respect to each other, whereby bending the board along one axis will not cause the board to become creased. Extruded plastics corrugated board can also be employed. It is also preferred that the thickness of the middle layer 73 corresponds with the thickness of the L-section members. Variations on the construction can be easily be implemented. It has been found that two layers are sufficient, of Tri-wall type 1700 and 440 grades, respectively, with a further layer of thicker material of reduced peripheral dimensions, defining, in conjunction with the L-section elements a channel, which receives the uppermost lip of the upstanding walls 55, in a closely fitting relationship. FIG. 5G and FIG. 5H show, respectively, an underside of the lid 56 shown in FIG. 5F with the insert 74 only present in FIG. 5H; the addition of the insert 74, upon sheet 73 defines a channel 77 where it lies adjacent the L-section member 5.

(34) FIG. 5I show how the lids 59 can be stacked one atop another in a simple fashion; as indeed the sleeve can be laid upon two sides and can be stored in a folded state, per FIG. 5J. FIG. 5K shows how the forces 80 arising from the weight of a barrel 79 upon a lid 59 are act through the walls of a container by the use of the laminated lid 59.

(35) FIG. 6A and FIG. 6B detail a still further embodiment wherein the element 57 is configured as a T-section element whereby the cover can prevent slippage of a secondary storage/transport assembly. In a stacked configuration, shrink wrap material can be applied about the two assemblies, whereby to secure the two assemblies together. Shrink wrap, also shrink film, is a material made up of a plastics polymer film. When heat is applied, it shrinks tightly over whatever it is covering. Heat can be applied with a handheld heat gun (electric or gas). Such a technique can be employed around three or more assemblies in a stacked arrangement, bearing in mind that the height of an assembly need not be a fixed height, with half-height assemblies being used for low-height products etc. Note also that fillings, e.g. card-based pellets manufactured from waste material may also be placed within a container to fill voids, which may otherwise allow unwanted movement within an assembly. FIG. 6C and FIG. 6D show how two adjacent storage/transport assemblies can be fastened using an L-shaped connector 75 to locate one storage/transport assembly 51 with respect to the lid of an adjacent transport/storage assembly 51.

(36) Details of another cover, not too dissimilar to FIG. 5F is shown in FIG. 6H and FIG. 6I, wherein an intermediate sheet material 73 has a cut-out portion 74 into which L-section member 57 can be inserted, as shown in FIG. 6I, with top layer 72 in place. It will be appreciated that other materials can be used. For example, the cover could also comprise formed plastics or resin impregnated fiber molded elements, strengthened as appropriate, whereby a more durable product can be provided.

(37) FIG. 7A shows how the cardboard sleeve 51 in accordance with one aspect of the invention can be positioned about pallet 20 with load 42 placed thereon. Cardboard sleeve is reinforced to a degree suitable for purpose: conveniently, the cardboard sleeve is made from industry standard single, double, triple or quadruple corrugated cardboard. In view of the ability of untreated cardboard to absorb water from precipitation or from the atmosphere, the cardboard should be adequately treated, by wax, resin, paint or other known waterproofing methods. When using corrugated board formed from 440 gm-2 wet strength Kraft paper, this type of board has a weather resistance which satisfies a 2-hour water immersion test without any ply separation.

(38) FIG. 7B shows how the cover or lid 61 fits closely over the outside of the sleeve. The inside channel 77 (FIG. 5H) being defined, to assist in securely locating the sides of the sleeve upon fitment of the cover to the transport and storage assembly. FIG. 7C shows how a second pallet 71 and load 72 can be placed upon the cover 61 on the first, lower pallet 20 and load 42. FIG. 7D shows an assembly of two pallets 20, 71 having loads 42, 72.

(39) With reference to FIG. 7E, twin apertures 52 are shown in wall 51, with each aperture having a U-section reinforcement member 43. It has been found that when the sleeve is formed from materials such as cardboard, the underside of the aperture benefits from having such a reinforcement member, formed from a material such as an extruded paper corner-board, in correspondence with the thickness of the cardboard panel 51, e.g. 15 mm, which products are available from many paper and cardboard suppliersfor example, they are made by companies such as ITW (under their ANGLEBOARD brand) and are available in various lengths and channel sections. FIG. 7F, FIG. 7G, FIG. 7H and FIG. 7I show cross sections through an aperture 52 within a wall 51 where reinforcement members of U-section 43, L-section 44, F-section 45 and top-hat section 46 are present. Conveniently, the product comprises a U-section channel, which can be clipped about the lower edge, although it is preferable that an adhesive is also used, such as a hot-melt glue. Other types of materials can be used to manufacture the channel members, such as extruded polypropylene, extruded aluminum, laminated glass fiber, laminated card etc.; composite board supplies are, however, plentiful and reasonably priced.

(40) In addition to a requirement for waterproofing, in order to strengthen the material, one or more of a number of options may be selected: the number of layers of sheets may be increasede.g. for a corrugated board, the sheets as a whole, or merely just the corner sections, can be reinforced so that they have two, three of more layers; any corrugated flutes could be filled with elongate support members or strengthening members, which could be plastic rod, metal, wood or any of a number of alternative materials which can be placed within the corrugation flutes, conveniently glued or otherwise permanently attached. Additionally, distinct materials such as batons or, preferably, sheet materials are provided where extra strength is required. Note that because of aperture 52 for the forks of a lifting mechanism such as a forklift truck, such strengthening means are conveniently applied only where weight can be easily be transferred from the lid to the base contact portion of the sleeve or sheath can be borne. For additional bearing strength, the single aperture 52 could be replaced by two single apertures, although the central support may well get easily damaged in use through inadvertent positioning of forklift truck forks against the cardboard and the support about the aperture 52, in particular.

(41) However, cardboard is not the only suitable material; Card/paperboard, plastics sheeting, formed plastics panels corrugated plastics sheeting, plywood and other sheet materials can be employed, the choice being determined upon requirements for specific use, such as weight to be supported, number of uses expected and such like.

(42) FIG. 7B shows how the cover or lid 61 fits closely over the outside of the sleeve. Although not required for all purposes, an inside groove could be defined, to assist in locating the sides of the sleeve upon fitment of the cover to the pallet assembly. FIG. 7C shows how a second pallet 71 and load 42 can be placed upon the cover 61 on the first, lower pallet 20 and load 42. FIG. 7D shows an assembly of two pallets 20, 71 each with load 42.

(43) FIGS. 8A, 8B and 8C show a similar situation of a pallet 20 with a load 42 being encased with a thermally insulating sleeve 81 and then fitted with a cover: the cover may have additional insulation or the insulation may be provided within the sleeve, by, for example a top layer comprising insulation. The addition of insulation may be performed by the provision of a separate sleeve about the outside of the sleeve 51 or may be attached by adhesive noting that whilst assisting in maintenance of a unitary sleeve is of advantage, there may well be difficulties in folding the double sleeved arrangement into a compact, minimum thickness flat-pack, especially if the insulation is, say, 10 cm in thickness. FIG. 8D shows how two insulated pallet assemblies are brought together and FIG. 8e shows two insulated pallet assemblies connected together. FIG. 8D shows how the external insulation provides foldable aperture covers or aperture doors 84 which are operable to allow the passage of the tines of a fork lift device through the apertures 52. By being cut through in part, certain plastics foam insulation materials may provide its own hinge, although a hinge element could also be separately provided. At rest, with the fork tines removed, the aperture covers will return to their rest position such that the edge either abuts the floor or the cover of the pallet below. Although not shown, connection means can be provided to ensure that the feet of an upper pallet do not move with respect either one or both of adjacent horizontally spaced pallet assemblies or to the cover of a pallet below. FIG. 8D also shows a further insulation member 83, which lies upon the pallet prior to placement of contents upon the pallet.

(44) FIG. 9A shows a still further system of attachment of insulation to a wall panel, where U-section elements 90 are placed along two opposite sides of a wall panel 55 i.e. top and bottom or, preferably, respective left and right sides of each panel. Two opposed U-shaped channels define slots operable to accept corresponding sides of an insulating panel 91, external to a wall of the sleeve 55. The U-section members can be attached with double sided tape, hot-melt glue or other adhesive; hook and loop fastenings could also be employed, whereby the U-shaped channels can be removed. With reference to FIG. 9B, a plan view of a still further embodiment of the invention is shown, wherein four different types of double-U channels are provide, whereby only four members need to be attached to retain four insulation panels 91, such low density polyethylene (LDPE) foam sheet, as shall be detailed below. FIG. 9C, FIG. 9D, FIG. 9E and FIG. 9F show four types of double-U channels, which are placed around the plan view of FIG. 9B; it can be seen that the different double-U channels per FIG. 9C, FIG. 9D, FIG. 9E and FIG. 9F correspond to the double-U channels employed at the respective corners identified c, d, e and f. Double-U channels 9c and 9d do not provide full corner insulation whilst double-U channels 9d and 9f can only be used on the corners which fold inwardly (i.e. the two panels fold towards each other) as the container is folded for storage etc. or otherwise be irremovably fastened.

(45) FIG. 9G shows a still further variation of insulation, wherein two sides of the sleeve are shown, whereby to enable two insulation panels 93, 94, which have respective rebates 95, 96 which are, ideally, slightly over size, whereby to ensure that air does not pass between adjacent rebate edges when placed together and in usei.e., the insulation panels are in compression along the contact mating surfaces.

(46) Conveniently, the insulation material would comprise of expanded or extruded polystyrene or polyurethane foam and have a thickness of approximately 50-80 mm. The corners of the rectangular container can be protected by heat formed corner edges, alternatively or additionally also being provided with L-section medium Density Fiberboard (MDF) corner protectors, in a similar fashion to the lips of the lid or top cover. The foam insulating panels of could also be of a laminated construction, whereby, using different densities of foam a lightweight yet stiff structure can be provided. Conveniently, these can be provided by commercially available HCFC-free expanded Polyethylene sheet (LDPE), where there is a closed cell structure with extrusion skin. This provides a low water absorption and water vapor transmission rate. Such foams typically have a high degree of resiliency and flexibility, excellent cushioning behavior and excellent thermal insulation properties, with a temperature stability of 40 C. to +70 C. Commercially available foams of such construction are manufactured by companies such as Knauf Insulation Ltd., Sealed Air Inc. etc.

(47) FIG. 10A shows a first variation of the sleeve configuration, wherein an aperture 97 is shown, defined within a wall 55 of the sleeve. FIG. 10B shows a still further variation, wherein the wall 98 has a cut-out portion, whereby only a top edge member 99 provides lateral support, although a removable member, convenientlybut not limited to suchbeing made from cardboard or comprising an L-shaped MDF member. FIG. 10C shows such a variation per FIG. 10A or FIG. 10B which is further provided with a cover 101 which is attached by fastenings 102. In the alternative, the cover may comprise a hinged door.

(48) FIG. 11 shows how the transport and storage embodiments made in accordance with the invention can be stacked one atop the other and side by side, without pallets being present, although palletsor indeed any products of a suitable width can be inserted through the apertures 57, 58.

(49) FIG. 12 shows how a number of transport and storage device in accordance with the invention can be provided within a warehouse 120. FIG. 13A and FIG. 13B show how a lorry 130 with a flat load bed 131 having open sides, in fully loaded and partially loaded configurations, respectively, can transport a number of transport and storage devices in accordance with the invention. Equally, small vans can be provided with a number of such transport and storage devices of reduced height, whereby the effective load capacity is increased substantially, which is especially useful for local delivery purposes. By having half-height transport and storage devices, the number of load areas can be increased, whilst being removable from the vehicle, upon the unfastening of any straps and linking members between adjacent deviceswhether to the side or above and below. It will be appreciated that if a larger item needs to be carried, the storage devices, with pallets or not can be either removed from the van or lorry or be stored in a flat-pack arrangement, to enable a particular load to be carried.

(50) In a further alternative, the sleeves may comprise specific insulation panels or such insulation panels may be fitted within the cardboard sleeve. The insulation panels may be separate elements or may also comprise a cylinder, which can be folded with corner assemblies by having interlocking tongue and groove members (not shown), it is also possible to substantially reduce the movement of air as between the exterior of the assembly and an interior of the assembly by the use of a flat base panel lying upon the support surface, or pallet and being of a slight oversize with respect to the internal walls, whereby air cannot pass between an insulating base member and the walls. The insulating inside panels need not extend to the feet of the cylinder walls, whereby the base is only enshrouded by the sleeve. A rebate within the lower portion of the insulating sidewalls and optionally of the base panel can effectively provide an airtight base and wall assembly. By using similarly dimensioned components at the top of the assembly, a good airtight seal at the top can also be provided, thereby increasing the thermal insulation characteristics of the completed box. Further ties may be required to prevent unwanted or accidental opening of the pallet enclosures when they are used.

(51) Referring now to FIG. 14, there is shown a top, exploded view of a transport/storage assembly with an insulated lid 142: below the lid, upon an insulating spacing element and coolant support 141 there is provided coolant packages 143 such as phase-change medium (PCM) packages which are selectively cooled to provide a temperature profile for a particular class of good for a period of timetypically 24-120 hourswhereby temperature sensitive goods can be transported within a specific temperature range. In an alternative, such coolant packages are provided in supports upon a wall.

(52) FIG. 15A shows a further embodiment, wherein a sleeve 150 has an F-section element 151 depending from an upper wall edge or lip. As seen in FIG. 15B, a C-section channel is provided into which corner 153 of lid 152 can be located, as seen in FIG. 15C. Opposite corner 154 of lid 152 is provided with an L-section element 155, either r side of the corner, in a similar fashion to the embodiment shown with reference to FIG. 5C and FIG. 5E. In use, corner 153 is inserted into the C-section channel, as the opposite edge 154 is located over the upstanding wall edges. To provide an alternative embodiment as shown in FIG. 15D.

(53) Whilst the present invention enables greater flexibility in the positioning of loads, whether employing a pallet or not, and the stacking thereof, such stacking should only be performed subject to the ability of base-level transport/storage assemblies to take additional weight. Dependent on the height, strength and stability of the assemblies and the ability of the operator to see clearly, taller stacks may only be built following detailed consultation with the manufacturer or other competent authority. To assist in the management of closely stacked and closely coupled load enclosures or pallet enclosures, the sleeves should be connectable with their associated pallets using a locking bolt or similar, noting that such locking bolts, preferably present a flush external surface finish, to enable adjacent coupling, but ideally such flush bolts can assist in the close coupling of transport/storage assemblies.
