Definitions

  • 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.
  • the invention provides a thermally insulating package comprising: an outer shell formed from a foam insulating material; a plurality of vacuum insulated panels removably received on the walls of the outer shell; and a plurality of phase change material (PCM) panels arranged within the vacuum insulated panels to define a payload space.
  • PCM phase change material
  • the invention provides a thermally insulating package comprising: an outer shell formed from a foam insulating material; a plurality of vacuum insulated panels removably received in pockets formed in the walls of the outer shell; and a plurality of phase change material (PCM) panels arranged within the vacuum insulated panels to define a payload space.
  • PCM phase change material
  • an array of PCM panels defines a payload space, and two layers of insulating material are provided around the PCM panels, namely a layer of vacuum insulated panels and a layer of foam insulation which removably receives the vacuum insulated panels.
  • This arrangement provides a compact, thermally efficient package which may be easily constructed.
  • the removable mounting of the vacuum insulated panels allows the panels easily to be removed and reused or replaced, the foam insulation acting to protect the vacuum insulated panels in use. This is important as if punctured, the vacuum insulated panels lose the majority of their thermal insulating properties.
  • the above construction may also be used with other thermal insulation materials inserted in the pockets of the outer shell.
  • the pockets may accommodate inserts of other thermal insulation materials, particularly inserts of a material having a lower coefficient of thermal conductivity than that of the material of the outer shell.
  • the invention provides a thermally insulating package comprising: an outer shell having a first coefficient of thermal conductivity; a plurality of insert panels having a second coefficient of thermal conductivity which is lower than the first coefficient of thermal conductivity received in pockets formed in the walls of the outer shell; and a plurality of phase change material (PCM) panels arranged within the panels to define a payload space.
  • PCM phase change material
  • the insert panels may be fixedly secured in the pocket, for example by an adhesive or mechanical fastening, but in preferred embodiments, the insert panels are removably mounted to allow for separation of the insert panels from the shell for replacement or recycling purposes.
  • the insert panel may be constructed simply as a block of material having the desired thermal conductivity, and could, for example, be simply cut from a sheet of such material to an appropriate size for insertion into the pockets.
  • the insert panel could of course be a vacuum insulated panel as discussed above, as this will, as is recognised by the skilled person, have a much lower coefficient of thermal conductivity than a foam material.
  • the insert panel is not a vacuum insulated panel (i.e. does not include a vacuum).
  • the outer shell may be formed from, or comprise, any suitable 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.
  • EPS expanded polystyrene
  • Neopor ® graphite impregnated EPS
  • EPS with a polyethylene additive e.g. Arcel ®
  • PUR polyurethane
  • polypropylene polypropylene
  • the insert panel may be, or comprise, PUR, or a Nano porous material, for example a polyurethane based aerogel material (for example Slentite ® ). Where the outer shell is a PUR, then the Nano porous material may be suitable.
  • PUR polyurethane based aerogel material
  • the skilled person will be able to choose appropriate combinations of materials to provide a desired thermal conductivity.
  • the inserts may be a mixture of materials or constructions.
  • the vacuum insulated panels or insert panels may be dimensioned such that they are received with a push fit with the pockets.
  • 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.
  • 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.
  • a separate protection element is preferably arranged between the vacuum insulated or other insert panels and the adjacent PCM panel.
  • 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.
  • a reflective coating or layer may be provided on one side of the board and a waterproof coating or layer provided on the other.
  • a metallised film may be provided on a waterproof plastics film to provide both reflective and waterproofing properties.
  • 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.
  • the protection element also extends over the exposed top edge of the vacuum insulated or other insert panel.
  • 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.
  • 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 invention provides, in combination, a vacuum insulated or other insert panel and a protection element therefor, said protection element comprising a folded sheet 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.
  • the protection element may be wider than the vacuum insulated or other insert panel so as to project beyond the edges of the vacuum insulated or other insert panel.
  • the pockets formed in the side walls of the outer shell are provided with respective slots to receive the projecting portion of the protection element. This adds a level of retention for the vacuum insulated or other insert panel in the side wall, apart from any press fit which may exist.
  • This slot may also serve an additional or alternative purpose, as will be described further below.
  • the PCM panel used in the packaging of the invention may take any convenient form.
  • it may take the form of a frustum of a right pyramid, as disclosed in EP-A-2221569 .
  • the PCM panel may comprise a phase change material sealed within a foil or film pouch and having a flange extending at least partially around the periphery of the panel.
  • Such panels are much simpler and cheaper to manufacture than the aforementioned shaped panels.
  • the peripheral flange may be used to assist in locating the PCM panel in the package.
  • the flange may be received in a slot a formed in a side wall of the outer shell.
  • This slot may be the same slot as discussed above which receives the vacuum insulated or other insert panel protection element (if present), or a separate, stand-alone slot. It is particularly advantageous to have a slot which retains both the flange of the PCM panel and a peripheral portion of a vacuum insulated or other insert panel protection element.
  • the invention provides a thermally insulated package comprising a thermally insulating shell of a foam material, one or more walls of said shell comprising an open topped pocket formed in a wall thereof, at least one side edge of said pocket having a slot formed therein.
  • 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 sheet, for example of board or plastics material, for example corrugated cardboard or corrugated plastics.
  • the support board 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.
  • 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.
  • 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 the vacuum insulated 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.
  • the PCM panel or panels may be such as to be generally flush with the surface of the pocket, or be recessed slightly therein.
  • the flange of the PCM panel may also act to help retain the PCM panel in a wall pocket of the package, for example in the lid of the package, as when pushed into the pocket, the flange will be folded back to provide an outwardly (with respect to the base of the pocket) pointing edge which will tend to engage the side wall of the pocket and thereby assist in retaining the PCM panel.
  • the invention provides a thermally insulating package comprising a wall having a pocket formed therein, said pocket receiving a PCM panel having a peripheral flange which upon insertion into the pocket folds to provide an outwardly directed edge engaging one or more side walls of the pocket.
  • the 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • EPS expanded polystyrene
  • Neopor ® graphite impregnated EPS
  • EPS polyethylene additive
  • PUR polyurethane
  • the lid 10 and the main body 8 are made from the same foam material.
  • vacuum insulated panels 12 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.

  • 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.
  • 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.

  • 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.
  • 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
  • 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.

  • 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.
  • the vacuum insulated panel protection element 14 also acts to help retain the vacuum insulated panel 12 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.

  • 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 external container 4 has handling openings aligned with the handle cut outs 70.
  • 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.
  • 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.

  • 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 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.
  • 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.
