Definitions

  • the present invention relates to a thermal-insulating liner, particularly adapted for use in packages and/or logistic services for transport of particularly sensitive or delicate goods.
  • liners which are made up of thermal-insulating material, such as polystyrene foam; these liners are interposed between the package walls and the goods, and can also house cooling elements such as dry ice pockets or the like.
  • known liners are of great thickness, which in turn will condition the package choice and therefore will give rise to a great bulkiness (even when objects of small sizes are transported) .
  • the important sizes of .the thermal- insulating liners of known type involve use of great storage spaces; in other words, the packages and liners of known type for said packages are to be stored in very big environments waiting for being used, which will adversely affect the operating costs as well as optimisation of the available work spaces.
  • liners of known type must be designed and made with rather complicated shapes, since complicated insertions between the different polystyrene pieces are often required; this involves great expenses for the moulds and a non-negligible difficulty for the operators when a complete package is to be prepared.
  • a further disadvantageous element for liners of known type resides in that, in spite of the complicated shape chosen for the liner, often penetration of air from the outside into the container occurs just the same, which will clearly bring about an undesirable heat transportation resulting in the goods losing their "low-temperature" state.
  • the present invention aims at solving the above listed problems.
  • the present invention aims at making a thermal-insulating liner offering a great efficiency in terms of thermal insulation while ensuring an overall compactness of the whole package (and consequently a great saving of room also in terms of storage and conservation of the empty packages) .
  • thermal-insulating liner offering an improved sealing capability to air penetration (or more generally, to penetration of atmospheric agents and/or external corpuscles) .
  • thermal-insulating liner in accordance with the present invention, described hereinafter in a preferred but non-limiting embodiment, and in the following illustrations given by way of example, in which:
  • Figs. 1 to 7 show a series of sequential perspective views of a liner in accordance with the invention at different moments of a folding process.
  • the liner in accordance with the invention is generally identified with reference numeral 1 and substantially comprises a foldable laminar body 2; this foldable laminar body 2 in turn has a plurality of folding lines 3 and a plurality of faces 4 (which are, for instance, disposed following the extension shown in Fig. 1, where it is possible to see thirteen faces 4 of rectangular conformation and folding lines 3 in the form of straight-line segments that are disposed close to two or more adjacent faces 4) .
  • the foldable laminar body 2 can be reversibly configured between at least one extended condition in which it defines a geometrical shape having a substantially planar developed form and an operating condition in which it defines a holding and thermal-insulation volume.
  • the foldable laminar body 2 at least in its operating condition has at least one insulation surface 5 (practically made up of a plurality of "layers" each of which corresponds to one face 4), comprising at least two pairs of faces 4 mutually superposed and folded along mutually transverse axes.
  • the mentioned insulation surface 5 is defined by a first pair of mutually superposed faces 4 folded along a first pair of folding lines 3 oriented along a first axis 4a, and by a second pair of faces 4 overlapping the first pair of faces 4 and mutually superposed and folded along a second pair of folding lines 3 oriented along a second axis 4b perpendicular to the first pair of axes 4a.
  • the folding lines 3 connect mutually adjacent faces with structural continuity; in this way, liner 1 carries out a topological division between the "outer” room and “inner” room, thereby offering a high capability of carrying out a physical separation (and therefore substantially preventing heat exchanges by convection) .
  • the particular "dual" superposition of faces 4 as above illustrated allows a very discontinuous and tortuous path to be provided which connects the inner room to the outer room; in this way the capability of perfectly closing liner 1 is ensured while at the same time heat exchanges by convection and/or air penetration are hindered as much as possible (and in addition they can exclusively take place through very limited room portions, which practically are the regions defined by adjacent edges of the pairs of faces mutually folded upon themselves) .
  • the presence of more than one insulation surface 5 can be provided; for instance, with reference to the sequence shown in Figs. 1 to 7 (and in particular to Fig. 7), it is possible to see that two insulation surfaces 5 can be present, each of them consisting of at least two pairs of faces 4 that are mutually folded and superposed along pairs of mutually transverse (and preferably perpendicular) axes, said surfaces being disposed on opposite parts of the thermal-insulating liner 1 itself in the operating condition of same.
  • liner 1 defines a substantially continuous side wall 6 and two base walls comprising the just mentioned insulation surfaces 5 which cooperate with the side wall 6 to define the holding volume .
  • the foldable laminar body is at least partly and preferably fully made up of a core consisting of a first thermal-insulating material (polystyrene foam for example, or more generally any closed-cell or open-cell foamed polymer) ; then also present is at least one outer layer of a second thermal-insulating material which advantageously can be an aluminium (or also an aluminium alloy) sheet (or more generally a metal material sheet) .
  • a first thermal-insulating material polystyrene foam for example, or more generally any closed-cell or open-cell foamed polymer
  • a second thermal-insulating material which advantageously can be an aluminium (or also an aluminium alloy) sheet (or more generally a metal material sheet) .
  • two layers of the second thermal-insulating material may be provided, each of them being disposed on opposite faces of the core.
  • the present liner 1 enables a package to be obtained that can be advantageously used for conservation and/or transport of medicaments and/or similar goods; said package comprises an outer containment body (a typical cardboard, plastic or metal box, for example) and at least one thermal-insulating liner 1 adapted to be at least partly inserted into the containment body itself; advantageously the thermal- insulating liner will be of the type illustrated above.
  • an outer containment body a typical cardboard, plastic or metal box, for example
  • at least one thermal-insulating liner 1 adapted to be at least partly inserted into the containment body itself; advantageously the thermal- insulating liner will be of the type illustrated above.
  • said package may comprise at least one opening face adapted to enable introduction of an object to be packaged; in this case the thermal- insulating liner 1 can show a superposition of at least two pairs of faces 4 folded along pairs of mutually transverse, and preferably perpendicular axes, at said opening face of the containment body (or in other words, it can have the insulation surface 5 disposed at said opening face, so as to enable introduction of the goods into the package with maximum ease) .
  • the package may also comprise cooling means associated with the containment body and/or the thermal-insulating liner 1; for maximum efficiency, the cooling means can be placed within said liner.
  • the step of defining the loading volume advantageously contemplates execution of a sub-step of folding and superposing a first pair of faces 4 along a first pair of folding lines 3 oriented along a first axis 4a, and a sub-step of folding and superposing a second pair of faces 4 overlapping the first pair of faces 4 along a second pair of folding lines 3 oriented along a second axis 4b transverse, and preferably perpendicular, to the first axis 4a.
  • the invention achieves important advantages.
  • liner 1 enables thicknesses to be limited to a maximum extent while maintaining a great "barrier effect" against thermal energy from the outside. This means that a greater useful volume will be available at the inside of the package, the inner temperature being the same; in other words, for a given object (or series of objects) packages of reduced sizes can be used.
  • the very reduced thickness of the present liner together with the fact that said liner 1 is foldable upon itself can be exploited for stowing a great number of liners in a very reduced space; this means that the not yet used packages can be arranged in a more efficient manner and they take up less room as compared with packages of known type.
  • liner 1 has a very simple geometrical shape that can be obtained through manual or automated operations that are also simple and cheap.
  • the intrinsic simplicity of shape of the present liner allows the same to easily and quickly conform (through folding and superposition operations) to the inner space of a package; therefore such an operation can be accomplished also manually by nonqualified staff and reach high efficiency with short work times.
  • the present liner has low production costs and high operating flexibility.
