Description

  • The present invention relates to a thermally insulated package.
  • Thermally insulated packages are widely used in the transportation of temperature sensitive goods, for example pharmaceuticals, biological samples, vaccines and the like. Typically the product must be maintained within predetermined temperature ranges, for example 2-8°C, 15 to 25°C or less than -20°C, over relatively long time periods, for example 48-120 hours. Various forms of such packaging are known using a variety of temperature control media (for example phase change materials) and insulation. An example of such a product is described in EP-A-2221569 . Such packaging, while providing good temperature control characteristics, does not lend itself to multiple use, and may prove to be relatively expensive.
  • The present invention seeks to provide a temperature sensitive package which provides good temperature control, but which is compact, robust and potentially less expensive than existing comparable products.
  • A temperature sensitive package having the features of the preamble of claim 1 is disclosed in WO 2012/094333 A1 .
  • The present invention provides a temperature sensitive package as set forth in claim 1.
  • In some embodiments, the inserts may be a mixture of materials or constructions. In order to facilitate assembly and integrity of the package, the vacuum insulated panels or insert panels may be dimensioned such that they are received with a push fit with the pockets.
  • In a preferred arrangement, the outer shell comprises a main body having a base wall and four or more side walls upstanding from the base wall, and a lid removably received on the main body to provide access to the interior of the package.
  • The main body part may be formed as a unitary body, but in some embodiments, it may be formed in two or more parts, for example where a larger package is required. The main body portion may therefore comprise a base part and one or more annular parts stacked onto the base part.
  • The vacuum insulated panel or insert panel receiving pockets may be provided in just some of the main body walls and/or in the lid, but in the preferred embodiment pockets are formed in all the walls and the lid. More than one pocket may be provided in one, more or all of the walls and lid. For example an array of panels may be mounted in the walls or lid. This may prove useful in larger packages. The pockets formed in the walls of the outer shell advantageously open towards the payload space. Also, for ease of assembly and construction, the pockets formed in the side walls of the package may have an open upper end to allow easy installation of the vacuum insulated panels therein.
  • This is in itself considered to be an advantageous feature, so from a further aspect, the invention provides a thermally insulated package comprising a plurality of side walls formed of an insulating foam material, one or more of said side walls having a pocket having an open upper end, and a vacuum insulated panel, or a panel of a material having a coefficient of thermal conductivity less than that of the foam material mounted in the pocket.
  • The respective pockets, and thus the vacuum insulated panel or other panels received in the pockets, may be separated by corner columns formed in the outer shell.
  • The vacuum insulated or other insert panels may be of any convenient shape, but will typically be hexahedral, for example cuboidal, for example square or rectangular cuboidal.
  • In order further to protect the vacuum insulated or other insert panels, a separate protection element is preferably arranged between the vacuum insulated or other insert panels and the adjacent PCM panel.
  • Preferably the protection element is formed from a sheet material, for example a corrugated board or corrugated plastics material.
  • One or both faces of the protection element board may be provided with a reflective, for example a foil for example a metallised film, coating or layer.
  • One or both faces of the protection element board may also or alternatively be provided with a waterproof coating to mitigate damage from moisture that may accumulate during use.
  • In one embodiment, a reflective coating or layer may be provided on one side of the board and a waterproof coating or layer provided on the other.
  • In a particularly preferred embodiment, a metallised film may be provided on a waterproof plastics film to provide both reflective and waterproofing properties.
  • Preferably the protection element extends around the vacuum insulated or other insert panel to protect all the exposed faces of the vacuum insulated or other insert panel not covered by the outer shell.
  • Thus, in an arrangement such as discussed above in which a vacuum insulated or other insert panel is received in an open topped pocket in the outer shell wall (and will therefore have an exposed top edge), it is preferred that the protection element also extends over the exposed top edge of the vacuum insulated or other insert panel.
  • In a particularly preferred arrangement, the protection element is formed from a folded board material having a first panel for covering a first face of the vacuum insulated or other insert panel, a second panel hingedly attached to the first panel for covering a top edge of the vacuum insulated or other insert panel and a third panel hingedly attached to the second panel for at least partially covering a second face of the vacuum insulated or other insert panel opposite the first face. This arrangement is advantageous in that the protection element may also be used to handle the vacuum insulated or other insert panel prior to its placing in the outer shell, as the user will be able to grip the vacuum insulated or other insert panel between the first and third panels. This reduces the likelihood of the vacuum insulated panel or other insert being damaged during installation.
  • In the preferred embodiment, the third panel does not cover the entire second surface but only a region thereof.
  • The pocket formed in the wall of the outer shell may have a recess to accommodate the third panel such that the rear face of the vacuum insulated or other insert panel may sit closely against the back surface of the pocket.
  • The PCM panel may be arranged within the pocket and may be selectively removable from the pocket through an open top end of the pocket, with the peripheral flange of the PCM received in the slot or slots when the PCM panel is arranged within the pocket.
  • Each pocket may have a pair of side edges that face each other, and a slot be provided in each of those side edges.
  • Each pocket may have a bottom side edge that faces an open top end of the pocket, and a slot be provided slot in the bottom side edge.
  • In certain embodiments, the flange may be provided on just one pair of opposed edges of the PCM panel. However, in other embodiments, the flange may extend along a single side of the PCM panel, any plurality of sides of the PCM panel or all sides of the PCM panel.
  • The PCM panel may be constructed from a plurality of PCM panel elements which may be mounted to a common support, for example a sheet of board or plastics material, for example corrugated cardboard or corrugated plastics. The support may include a flange to receive the flanges of the individual PCM panel elements and therefore be used to engage the slot in the outer shell.
  • The flanges of the individual PCM panels may be received by the support board flange by arranging the PCM panels on the support board with the flanges of the PCM panels on and in contact with the flange of the support board. In particular embodiments, the flanges of the PCM panels are connected to the flange of the support board with any suitable connecting material for example an adhesive, staples, clips, snap connectors or other connectors. In other embodiments, the flanges of the individual PCM panels may be molded or thermally bonded to the support board flange or received in pockets or slots formed in the support board flange.
  • The flange of the PCM panel or panels is preferably formed generally co-planar with one face of the panel. Most preferably that face of the PCM panel or panels is arranged facing a vacuum insulated panel or other insert panel.
  • The PCM panel or panels may be arranged to project out from the pocket(s) formed in the walls of the outer insulating shell. Alternatively, the PCM panel or panels may be such as to be generally flush with the surface of the pocket, or be recessed slightly therein.
  • A payload may be placed directly in the space defined by the PCM panels. Preferably, however, it is received within an inner container, for example a cardboard box which is received in the payload space.
  • The inner container may be foil, for example metallised foil faced. It may, additionally or alternatively be provided with a waterproof, e.g. plastics, coating. A metallised plastics film may provide both functions. Alternatively, the inner box may be made from a corrugated plastics material.
  • The inner container may be dimensioned so as to engage the outer shell, thereby to assist in locating the payload. For example, the inner container may engage the corner posts defined between adjacent side wall pockets. The inwardly pointing edge of the pockets may be provided with a chamfer or groove to receive a corner of the inner container.
  • The outer shell may be received within an outer container, for example a corrugated board container or a corrugated plastics , for example Correx®, container, for shipping, to provide some protection to the outer shell.

  • With reference to Figure 1, a package 2 in accordance with the invention is illustrated in an exploded view.
  • The package 2 comprises an external container 4, in this case a simple corrugated cardboard box. Inside the external container 4 is provided an outer shell 6 (shown in cross section in Figure 6) comprising a main body 8 (shown in Figure 4) and a lid 10. The main body 8 and the lid 10 are moulded components formed from an insulating foam material such as expanded polystyrene (EPS), graphite impregnated EPS (e.g. Neopor®), EPS with a polyethylene additive (e.g. Arcel®), polyurethane (PUR) or polypropylene. Preferably the lid 10 and the main body 8 are made from the same foam material.
  • Arranged within the outer shell are arrays of vacuum insulated panels 12, vacuum insulated panel protection elements 14, 16, PCM panels 18 and a payload container 20.
  • As can best be seen from Figure 4 to 6, main body 8 is a unitary body and comprises a base wall 22 and four upstanding side walls 24. The base wall 22 is formed with a central, square sectioned, upwardly open pocket 26. Each side wall 24 is provided with a pocket 28. The top 30 and inwardly facing side of each side wall pocket 28 is open. The adjacent side wall pockets 28 are separated by generally square section corner posts 32 formed in the body of the outer shell. The pockets 26, 28 are preferably integrally moulded into the main body 8. A lip 34 projects upwardly around the upper edge of the main body 8, with platforms 36 being formed atop the corner posts 22.
  • The opposed sides 38 of each side wall pocket 28 defined by the corner posts 32 are provided with slots 40 along their length. As best seen in Figure 7, the base wall 22 is also provided with respective slots 42 aligned with the side wall slots 40 to form a generally U-shaped slot in each side wall 24. In addition, the back surface 44 of each side wall pocket 28 is formed with a shallow recess 46. The base wall 22 is also provided on one or more sides, preferably on two opposed sides, with recesses 48. The purpose of these various formations will be described further below.
  • As will be best understood from Figure 1, the base wall pocket 26 receives, from the bottom up, a square vacuum insulated panel 12, a square vacuum insulated panel protection element 16 and a square PCM panel 18. Although shown as square in this embodiment, the respective panels may be other shapes, for example rectangular, in other embodiments.
  • The vacuum insulated panel 12 is preferably a slight push fit in the pocket 26 to firmly locate the panel 12. The vacuum insulated panel 12 is, as is are the other vacuum insulated panels 12 in the package, of a standard industry construction, namely an evacuated porous core for example of fumed silica encapsulated in an airtight film, more particularly a metallised foil film. The various vacuum insulated panels 12 are all of the same shape and size in this embodiment, but depending on the shape of the payload, the vacuum insulated panels 12 may be of different shapes and sizes.
  • As illustrated in Figure 1, the vacuum insulated panel protection element 16 is a square section of corrugated board material, for example E flute (2mm) or B flute (3mm) corrugated board material which may be coated on one or preferably both faces with a metallised foil film and/or a waterproof coating. This will protect the vacuum insulated panel 12 from the PCM panel 18 above.
  • The PCM panel 18 in this embodiment is formed from a PCM material encapsulated in a plastics film. The particular PCM used will depend on the desired temperature for the payload, but in this embodiment it is tetradecane. This material has a phase change point of 4.5°C making it suitable for a payload requiring a temperature range of 2-8°C. Other phase change materials, such as mixtures of salt hydrates, have phase change points ranging, depending on their composition, from -20°C to +20°C
  • As can be seen from, for example, Figure 2, the PCM panel 18 has a peripheral flange 50 which extends generally co-planar with one face of the PCM panel 18. This flange 50 is formed from the encapsulating film material of the PCM panel 18 and is formed during the PCM panel manufacturing process.
  • The PCM panel 18 is preferably sized slightly smaller than the base wall pocket 26 such that there is sufficient space around the periphery of the PCM panel 18 to allow the flange 50 to flex upwardly as the PCM panel 18 is inserted into the pocket 26. This flange 50 will help locate the PCM panel in the pocket 26.
  • The various PCM panels 18 of this embodiment are all of the same shape and size in this embodiment, but depending on the shape of the payload, the PCM panels 18 may be of different shapes and sizes.
  • The recesses 48 provided in the base wall pocket 26 allow a user to insert his or her fingers under the vacuum insulated panel 12 and PCM panel 18 in order to remove the panel from the pocket 26.
  • Turning to the side wall pockets 28, as can be seen from for example Figure 3, these each receive, from back to front, a vacuum insulated panel 12, a vacuum insulated panel protection element 14 and a PCM panel 18.
  • As discussed above, the vacuum insulated panel 12 and the PCM panels used in this embodiment are the same as those used in the base wall 22 and the lid 10. However, the vacuum insulated panel protection element 14 is different from those used in the base wall 22 and the lid 10. The vacuum insulated panel protection element 14 can be seem most clearly in Figure 10 where it is shown in position around a vacuum insulated panel 12. The vacuum insulated panel protection element 14 is made from a corrugated board material, for example E (2mm) flute or B (3mm) flute corrugated board with a foil e.g. a metallised film, and/or waterproof plastics coating on one or preferably both sides. The element 14 has a first panel 52 which covers the front face 54 of the associated vacuum insulated panel 12 and extends beyond the lateral and bottom edges thereof. Hingedly attached to the first panel 52 is a second panel 56 which covers the upper edge 58 of the vacuum insulated panel 12. Hingedly attached to the second panel is a third panel 60 which extends over only an upper part of the rear face 62 of the vacuum insulated panel 12.
  • The vacuum insulated panel protection element not only acts to protect the vacuum insulated panel 12 in situ in the package 2, but also facilitates its handling. Specifically, a user can fold the vacuum insulated panel protection element 14 around the vacuum insulated panel 12 and then grip the vacuum insulated panel 12 between the first and third panels 52, 60 for assembly of the vacuum insulated panel 12 into the package 2.
  • Moreover, as can be seen from Figure 5, for example, the vacuum insulated panel protection element 14 also acts to help retain the vacuum insulated panel 12 in the side wall pocket 28. The portion 64 of the vacuum insulated panel protection element 14 which projects beyond the vacuum insulated panel 12 engages in the slots 40 formed in the corner posts 32. The lower projecting part will engage in the slot 42 formed in the base wall 28. Thus, even though the vacuum insulated panel 12 may be a slight push fit in the side wall pocket 28, the vacuum insulated panel protection element also helps retain the vacuum insulated panel 12 in position.
  • The vacuum insulated panel 12 and vacuum insulated panel protection element 14 may be assembled into the pocket 28 from the top of the pocket 28. Alternatively, they may be assembled consecutively. In that case the vacuum insulated panel 12 may be slid into the pocket 28 from above or pushed in from the open face of the pocket 28, and the vacuum insulated panel protection element 14 then slid into the slot 40.
  • It will be understood that, when assembled, the third panel of the vacuum insulated panel protection element 14 is received within the recess 46 formed in the base wall of the pocket 28. The recess 46 is of substantially the same shape and depth as the third panel 60. This allows the major part of the rear surface 62 of the vacuum insulated panel 12 to closely engage the rear wall of the side wall pocket 28.
  • The side wall pockets 28 also receive the PCM panels 18. It will be seen again from Figure 5 that the peripheral flange 50 of the PCM panel 18 is received in the slots 40 formed in the corner posts 32. The lower edge of the flange 50 will be received in the base wall slot 42. This interengagement of the flange 50 within the slots 40, 42 helps retain the PCM panels 18 within its side wall pocket 28. In assembly, the PCM panel 18 may simply be slid into position from above.
  • The PCM panels 18 are dimensioned such that after assembly they will lie generally flush with or project slightly beyond the faces of the corner posts 22.
  • As can be understood from Figure 5, when the base wall pocket 26 and side wall pockets 28 have been filled with the appropriate vacuum insulated panels 12, vacuum insulated panel protection elements 14, 16 and PCM panels 18, the payload container 20 may be placed in the payload space defined between the PCM panels 18. The corners of the payload container 20 may engage tips 64 of the corner posts 22 for location purposes. The payload container 20 is preferably of a board material, particularly a corrugated board material, which may be provided on one or preferably both surfaces with a foil, for example a metallised film coating and/ or with a waterproof plastics coating, the latter to protect from any moisture which may accumulate in use.
  • When the payload container is positioned within the payload space, the lid 10 of the package 2 may be fitted.
  • The lid 10 is also moulded from a foam material, preferably the same foam material as the main body 8. As can be seen in Figure 3 for example, it has opposed handle cut outs 70 and recesses 72 for receiving for example an RFID tag or other logging device. The external container 4 has handling openings aligned with the handle cut outs 70.
  • As shown in Figures 7 to 9, the lid 10 has a depending land 76 which extends around its entire periphery and which locates within the lip 34 of the main body 8. The land 76 is provided with a relief groove 78 which receives the upwardly projecting flanges 50 of the PCM panels 18 mounted in the side wall pockets 28. The lid 10 also has a pocket 80 for receiving a vacuum insulated panel 12, vacuum insulated panel protection element 16 and PCM panel 18. The vacuum insulated panel 12 may be a tight fit within the pocket 80. The vacuum insulated panel protection element is the same as that provided in the base wall 22. The PCM panel 18 is sized such that the flange 50 thereof will fold inwardly as the PCM panel 18 is inserted into the pocket 80 whereby, as shown in Figure 9, the flange 50 will tend to splay outwardly into the walls of the pocket 80 to assist in retaining the PCM panel 18 in the pocket. Specifically, the lower edge of the folded down flange 50 will tend to dig into the walls of the pocket 80 to provide resistance to the PCM panel falling out of the pocket 80.
  • As illustrated in Figure 6, the lid 10 is also provided with opposed recesses 82 which will allow a user to insert his or her fingers under the PCM panel 18 and the vacuum insulated panel 12 to facilitate their removal.
  • With the lid 10 positioned on the main body 8, the external container 4 may be closed for shipping.
  • It will be understood that after use, the package 2 may be reused, the PCM panels 18 being suitably reconditioned. The other components may be reused substantially as they are.
  • The above description relates to just one embodiment of the invention. However, it will be appreciated that modifications may be made to that embodiment without departing from the scope of the invention.
  • For example, as discussed above, the various panels need not be square but could be rectangular. Also, the package need not be cubic, but could be a rectangular cuboid in shape.
  • Also, depending on the size of the container, the manufacture of the main body 8 may be simplified by forming it in two or more parts. Such an arrangement is illustrated in Figure 11.
  • In this construction the main body 8 is formed from a base part 8a and an annular upper part 8b. The base part 8a has an upstanding lip 82 which receives a depending lip 84 of the upper part 8b. The upper part 8b receives the lid 10 as in the earlier embodiment. The shapes of the pockets 26, 28, 80 are unchanged from the earlier embodiment and the same vacuum insulated panels 12, protection elements 14, 16 and PCM panels 18 are used. This construction is useful for larger packages where mould size restriction may not allow the full height of the main body 8 to be formed in a single operation.
  • It will also be understood that more than one pocket 26, 28, 80 may be provided in one or more of the side walls 24, base wall 22 and lid 10. Such an embodiment is illustrated in Figure 12.
  • In this embodiment, each side wall 24 is provided with two side wall pockets 28, separated by a rib 90. Opposed faces of the rib 90 are provided with slots 92 for receiving the vacuum insulated panel protection element 14 and flanges 50 of the PCM panels 18. The base wall 24 and lid 10 are provided with four pockets 28, 80.
  • Of course, the number of pockets provided on each wall may be varied to give a package of the desired dimensions. For example, if a rectangular container is required, the respective side walls 24 may each have different numbers of pockets 28.
  • It will also be appreciated that each PCM panel 18 may contain more than one PCM element. For example two or more PCM elements may be received one above the other in the side wall pockets 28. To facilitate such a construction, a plurality of PCM elements may be mounted to a common support, as shown in Figure 13.
  • In this embodiment, two PCM elements 118, each having a peripheral flange 150, are mounted, e.g. bonded, to a support member 100., The support member 100 may be a sheet material such as cardboard, corrugated cardboard or corrugated plastics, and it has a peripheral flange 102 on at least one pair of opposed side edges which receive the flanges 150 of the PCM elements118. This flange 102 may be received within the slots 40 provided in the side wall pockets 28 to assist in supporting the PCM elements 118.
  • In a yet further modification, the materials of the outer shell 6 and the panels 12 may be chosen so as to provide a desired thermal conductivity. In particular, the insert panels 12 may be made from a material which has a lower coefficient of thermal conductivity than that of the outer shell 6.
  • Thus the outer shell 6 may be made from expanded polystyrene (EPS) which typically has a thermal conductivity of about 0.036 W/m-K, graphite impregnated EPS (e.g. Neopor®) which typically has a thermal conductivity of about 0.032 W/m-K, EPS with a polyethylene additive (e.g. Arcel®) which typically has a thermal conductivity of about 0.038 W/m-K, or polyurethane (PUR) which typically has a thermal conductivity of about 0.022 W/m-K. In the case of an EPS based outer shell material, the insert panel 12 may be PUR which, as can be seen has a lower coefficient of thermal conductivity. In the case of any of the outer shell materials used, the insert panels 12 may be a Nano porous material such as BASF Slentite® which typically has a thermal conductivity of about 0.016 W/m-K. A typical vacuum insulated panel will typically have a thermal conductivity of about 0.004 W/m-K. Thus the materials of the outer shell 6 and the thermal insulation insert panels 12 may be chosen to give the desired thermal conductivity.
  • Such embodiments may use any of the constructional features described above, the only difference lying in the nature of the materials used.
