Definitions

  • the present invention relates to a transport container for use in safely transporting products.
  • Transported products generally need to be protected from physical shocks and damage, and therefore there is a general need for transport containers which provide impact resistance to the products they contain.
  • Some products are temperature sensitive and hence may require either being kept cool or being protected from chilling during transit.
  • Examples of products that need to be kept cool whilst being transported from place to place, for example by postal or courier services (particularly from a manufacturer or distributor to a consumer) include frozen food products, pharmaceutical and biochemical products (including diagnostic agents), and organs for transplantation.
  • Examples of products that, by contrast, need instead to be protected from chilling during transport (particularly, for example, from freezing as part of air cargo), include heated foodstuffs and further pharmaceutical products, as well as blood products.
  • Both types of goods conventionally have been transported in thermally insulated, rigid containers such as boxes fabricated of polystyrene foam.
  • polystyrene boxes can be fragile and are expensive to manufacture, as well as being space-inefficient.
  • French Patent Application No. 7808251 (published as FR-A-2419884) discloses a rigid container comprising sides having at least two layers of sheets of plastic material laminated with metal, which provide thermo-insulation of any contents.
  • the sheets are metalised, the container cannot be collapsed and remains in a bulky, non-collapse state even when no contents are held.
  • NL 83368 C discloses a transport container, comprising a liner which is collapsible, in a direction transecting a "vertical axis" of the container, such that the container is configurable between states that are non-collapsed and at least partially collapsed.
  • the preamble of claim 1 is based on this disclosure.
  • the container should preferably also provide a space efficient outer shape when full of transportable products, so that the number of containers that can be transported per given transit space may be maximised.
  • the present invention provides a transport container, comprising a liner which is collapsible, in a direction transecting a "vertical axis" of the contalner, such that the container is configurable between states that are non-collapsed (for holding transportable contents therein) and at least partially collapsed (for compact storage when empty); characterized In that the collapsible liner is substantially rigid, and further characterized in that the container further comprises a plurality of layers of flexible material surrounding the liner.
  • vertical axis is meant an axis extending through opposite ends of the liner, preferably at least one such end of the liner being open or openable to allow a transported product to be inserted Into, and removed from, the transport container.
  • the (or each) open or openable end of the liner is closable by means of a respective substantially rigid plug (described below).
  • the use of the term “vertical” is not intended necessarlly to denote any particular orientation with respect to gravity, although the transport container will usually be oriented with the "vertical axis" of the liner in a substantially vertical orientation with respect to gravity in order to allow the insertion and/or removal of a product into and out of the transport container conveniently.
  • the flexible material preferably is impact resistant. Additional or alternatively the flexible material may be resiliently compressible. In some embodiments of the invention the flexible material may be elastic.
  • the flexible material may be thermally insulating
  • the transport container includes one or more substantially rigid plug(s) for insertion inside the liner when the container is in its non-collapsed state.
  • the invention preferably provides a transport container comprising a substantially rigid liner, a plurality of layers of flexible material surrounding said liner, and one or more substantially rigid plug(s) inserted inside the liner to retain the liner in a non-collapsed configuration (for holding transportable contents therein), wherein the, or each, plug is removable from the liner and when so removed the liner Is collapsible, in a direction transecting a vertical axis of the container, such that the container is configurable between its non-collapsed state and an at least partially collapsed state (for compact storage when empty).
  • the liner provides a means for altering the shape of the container between collapsed and non-collapsed conjurations, whereas the surrounding flexible material provides the container with appropriate additional structural integrity (In combination with the liner) and preferably also thermally and/or physically protective insulation properties. Goods can be stored safely Inside the non-collapsed liner, which Is kept in such a configuration by means of the one or more plug(s), once the latter have been inserted.
  • the transport container of the present invention is constructed such that it can be collapsed into a space saving, flattened configuration when empty, and hence can be easily stored and moved prior to, or after, holding any transportable contents.
  • the collapsible container of the present invention is preferably constructed of materials that can be re-cycled and thus are ecologically friendly.
  • the pre-chilled product may be placed inside the non-collapsed container together with a desired quantity of "dry Ice” in granulated, sliced or chunk form,
  • a separate sealed bag containing a refrigerant, or warmed liquid respectively can be placed inside the container together with the product.
  • the flexible material comprises a plurality of layers of the flexible material, and this generally has the advantage of increasing its thermal and/or physical Insulation properties.
  • the flexible material may comprise one or more sheets or loops wound around the liner one or more times, thereby providing a plurality of layers of flexible material.
  • the flexible material preferably comprises a polymeric foam material e.g, polyethylene foam.
  • the plug(s) can be removed, as mentioned above, so allowing the container to be flattened by an operator into Its space saving, collapsed configuration. In this way, multiple flattened containers can be stored or transported without taking up substantial room.
  • a second aspect of the invention provides a method of constructing a transport container according to the first aspect of the invention, the method comprising either:
  • the liner and the flexible material may have greater an the required vertical length for a single transport container, and the method may include the step of cutting the assembled liner and flexible material into a plurality of assembled liners and associated flexible material, thereby to form a plurality of transport containers therefrom.
  • the method also includes the step of inserting at least one of said plug(s) inside the liner to maintain the non-collapsed state of the container.
  • the transport container according to the invention preferably further comprises an envelope surrounding the exterior of the flexible material.
  • the method according to the second aspect of the invention preferably further comprises the step of surrounding the exterior of the flexible material with an envelope.
  • the envelope is preferably a pressure envelope which provides compression to the flexible material and/or the liner, at least when the liner is In its non-collapsed configuration.
  • the envelope may be shrunk around the flexible material, preferably by heat-shrinkage, e.g. by means of a hot air gun-
  • the envelope is bonded to at least part of the exterior of the flexible material, for example by means of shrinkage, especially heat-shrinkage, of the envelope.
  • the method according to the second aspect of the invention includes the following additional steps:
  • the fully constructed container has an optional envelope, when present, that is preferably bonded (In separate stages) to both the outermost of the plurality of layers of the flexible material and to the one or more plug(s).
  • an optional envelope when present, that is preferably bonded (In separate stages) to both the outermost of the plurality of layers of the flexible material and to the one or more plug(s).
  • the flexible material, the liner, and the, or each, plug, may be contained within a box, for example a box in the form of a carton.
  • the box is preferably collapsible, and preferably the collapsed liner and flexible means (preferably also with one or more plug(s)) may be supplied together with the collapsed box.
  • the assembled liner, flexible materiel and inserted plug(s) preferably all enclosed within an envelope
  • the box therefore provides additional structural integrity and protection to the remainder of the transport container, and therefore provides additional protection to the product(s) contained therein.
  • the box (e.g. a carton) is preferably made from cardboard, especially reinforced cardboard (e.g. corrugated cardboard).
  • a collapsible transport container is shown in Figures 4A to C that has been fully constructed in its non-collapsed state and has been sealed, and thus is ready for transporting goods (not shown) previously placed within the cavity 1 of the container.
  • the container comprises a liner 2 that optionally has a rigidity substantially in a direction parallel to a vertical axis C-C' of the container.
  • the container is collapsible, in a direction transecting this vertical axis, between a non-collapsed state, as shown in Figures 4A to C, and an at least partially collapsed state, as shown in Figures 2A to E and Figure 3A.
  • Flexible material 3 (which is preferably thermally insulating and/or impact resistant) surrounds the liner 2 so as to form sides of the container with two insulating plug(s) 4 inserted inside the liner 2 in its non-collapsed state.
  • the liner 2 itself may be provided with flaps (not shown) at either end, which can be inserted instead of the plugs 4, and which can act as a lid and a base for the container.
  • flaps may simply be unitary pieces of material or may be provided in a segmented form so as to form "crash-lock" ends to the container.
  • flaps When flaps are present they may be kept in their inserted position by optional locking means, or may be retained simply by bonding the envelope 5 directly to them.
  • plugs 4 and flaps may be employed, if desired.
  • containers can be constructed that are collapsible in directions that transect the vertical axis C-C' at various angles
  • the container shown in the Figures is collapsible in a direction that is perpendicular to the vertical axis.
  • the liner 2 is usually extruded in a flat form and then die stamped to shape (see Figure 1A). Cardboard liners 2 are then folded and their ends are glued together, whereas plastic ones are creased and the ends are then heat bonded (see Figure 1 B). If such a plastic liner 2 is made of a foam, it can be extruded with integral shallow mitred grooves 7 that allow the liner 2 to be easily folded rather than creased.
  • Preferred materials for a plastic liner 2 are blown, or solid, low-density polyethylene, polypropylene, nylons and so forth.
  • the plugs 4 may be of similar materials, if desired, although are typically extruded in such a manner as to be more rigid than the walls of the liner 2. Further, the flexible material 3 may also be extruded from the same or similar types of blown plastics as mentioned above.
  • the material forming the walls of the liner 2 may optionally be corrugated and examples of such material include corrugated cardboard, corrugated plastic (such as CorrexTM and TwinplastTM) and so forth.
  • the corrugations of such material are fluted in a direction substantially parallel to the horizontal plane containing the line B-B' (see Figure 4A) of the container.
  • This type of fluting provides the container with substantial rigidity, since in the non-collapsed position the corrugations tend to buckle somewhat. This pushes the corners of the liner 2 outwards, so increasing the tension in the sides of the container.
  • the presence of the inserted rigid plug(s) 4 provides the container with extra lateral rigidity.
  • the container's overall rigidity is an important property that enables the transported goods to be insulated from physical shocks during transit.
  • Vertical rigidity is predominantly provided by the rigidity of the walls of the liner 2.
  • the air trapped within the flutes of the corrugations can also provide a degree of thermal insulation of the goods held within the container.
  • the corrugations may be fluted in a direction substantially parallel to the vertical plane containing the line C-C' (see Figure 4A again).
  • the transport container shown in Figures 4 A to C further comprises a heatshrunk envelope 5 that applies pressure around the exterior of the sides of the container, especially when the container is in its non-collapsed state.
  • the envelope also contributes to providing the container's overall rigidity.
  • the flexible insulating material 3 comprises a plurality of layers, which optionally consist of at least one sheet of the material wound a plurality of times around itself.
  • the air trapped within the layers can provide the container with increased properties of insulation.
  • the material 3 is in the form of a winding, the innermost and outermost edges are typically secured by heat bonding.
  • the layers of the winding can still move relative to one another.
  • the container may remain in its non-collapsed state despite the absence of any plug(s) 4.
  • the plugs do, of course, need to be inserted if any contents are to be securely held inside the container.
  • the envelope 5 can comprise loose edges 6 that protrude away from the plurality of layers of flexible insulating material 3. Such loose edges 6 can be bonded (see Figure 4 C) to the plugs. Alternatively, the loose edges 6 can be bonded (not shown) to the edges of the plurality of layers of flexible insulating material 3.
  • At least a portion of an outermost layer of the flexible insulating material 3 is bonded to an adjacent, inner layer of said flexible insulating material 3.
  • the liner 2, the plurality of flexible layers, the plugs 4 and the envelope are made of a convenient thermoplastic such as a low-density polyethylene.
  • the envelope 5 is heat-shrinkable for ease of sealing the container. It is particularly preferred for all components to be made of the same thermoplastic.
  • plugs 4 shown in the Figures are used as container closure means, alternative plugs 4 can be used as content separator means for sub-dividing the cavity 1 into compartments. Dividing the container in this manner can also help give the container extra physical strength to protect any contents during transit.
  • the plugs 4 may be simple disks of material or, as illustrated in the Figures, may be cut into the form of blocks with an outer protruding ledge 8 for closing over the edge of the flexible insulating material 3.
  • relatively simple disks when relatively simple disks are used, they may be constructed to have slits 9 cut into one of their major surfaces (see Figure 3), so as to be adapted to receive the ends of the liner 2.
  • slits 9 cut into one of their major surfaces (see Figure 3), so as to be adapted to receive the ends of the liner 2.
  • such disks can be used to cap the latent openings at the ends of the liner 2, so as to form a base and lid of the container.
  • This type of arrangement is particularly easy to assemble if the ends 10 of the liner 2 protrude outwards away from the flexible means 3, that is when the latter is shorter in the length than the liner 2.
  • the walls of the liner form a tessellating shape when the liner is in its non-collapsed state.
  • the outer shape of the fully constructed container filled with goods will allow multiple containers to be packed efficiently together without wasting space during transit.
  • the container can be assembled (either by its manufacturer or by a subsequent customer) from a kit comprising the following components: at least one of the liners 2, each being surrounded by an amount of flexible insulating material 3; at least one set of a couple of plugs 4; and at least one envelope 5.
  • kit and thus the transport container, can be easily constructed by way of the following method steps which define a procedure that is sequentially illustrated by the accompanying drawings in an order starting from Figure 2A and finishing at Figure 3C.
  • a liner 2 is placed in its collapsed state (see Figures 2A and B) around a flat mandrel (not shown).
  • a plurality of layers of flexible insulation material 3 is wound around the outside of the liner 2 (see Figures 2C and D). If a relatively long mandrel is used, multiple container units may be produced at the same time.
  • the partially constructed container is removed from the flat mandrel and may be supplied in this flattened state.
  • a manufacturer may supply such a product directly to a customer wishing to transport goods, in a kit form (as mentioned above) that further comprises the required separate plugs 4 and separate envelopes 5.
  • the long, partial construction that is removed from the mandrel can be cut into separate container units, so that multiple container units can be simultaneously produced.
  • the customer can bond at least part of each envelope 5 around the outside of the plurality of layers of each container with the liners 2 still in their collapsed state (as illustrated in Figures 2E and F and Figure 3A).
  • plugs 4 can be inserted at each end of the liners 2. This helps to maintain the non-collapsed state of the liner of each container, as shown in Figures 3B and C, and the goods can be placed inside the container. Finally, the loose protruding edges 6 of the envelope of each container can be bonded to both plugs 4, so as to seal the contents within the container.
  • the bonding steps are achieved by heat shrinking, for example when the envelope 5 is also a thermoplastic material.
  • Such an envelope 5 is typically formed as a mono-extrusion of low density polyethylene, polypropylene, nylon and so forth.
  • the container need not only be substantially rectangular, but can be generally any shape, including substantially polygonal shapes, as desired, when three or more walls are present.
  • a customer can purchase a kit that can be easily assembled into a transport container comprising components composed of a single, re-cyclable material.
  • the assembled container can be efficiently and simply sealed, for example, by using only a single piece of bonding machinery such as a heat-shrinking device.
  • the resultant transport container is easy to store when it is empty, because it is at least partially collapsible and can therefore be flattened to a compact state. It may also have a space efficient outer shape in its non-collapsed state, so that the number of such containers that may be transported per given transit space can be maximised.
  • Figure 6 shows an alternative embodiment of liner 12 in which the collapsibility of the liner is provided by means of longitudinal folds 14 in a pair of opposing sides 16 of the liner, as indicated by the arrows.
