Definitions

  • This invention relates to thermally insulative containers, particularly though not exclusively for transporting pharmaceutical products and other products having application to health care, particularly primary health care.
  • the common vacuum flask consisting of two concentric thin glass walls separated by a very high vacuum region, provides a thermally insulative container with extremely good thermal insulation. It is however a very fragile construction and is normally used only for holding fluids.
  • thermal containers in the form of boxes or bags are in common use, where the wall panels contain a porous plastic foam material, e.g. polyurethane or expanded polystyrene typically with pore diameters between 10 and 100 microns ( ⁇ m).
  • foam material e.g. polyurethane or expanded polystyrene typically with pore diameters between 10 and 100 microns ( ⁇ m).
  • the foam material must be thick, of the order of centimetres or inches, and is therefore too bulky for many mobile applications, particularly for primary health care situations, where for example a nurse has personally to transport products.
  • VIP includes a compound such as fumed silicon dioxide having pore diameters less than 1 ⁇ m in diameter, and preferably in the range 10 to 100 nanometres (nm), enclosed in an air tight envelope, with a moderate vacuum pressure, for example of less than 10 mbar existing within the envelope.
  • the pore diameters are so small that heat convection by movement of air is prevented or at least significantly restricted, since air molecules within the pores are trapped and prevented from significant movement.
  • VIP will be referred to herein as "vacuum insulation panels of the type described”.
  • containers for transporting products for health care applications particularly hand portable containers for primary health care applications, safely, and under thermally insulated conditions, the containers desirably being compact and not bulky, at least when stored.
  • the present invention provides a thermally insulative container, foldable to a flat pack for storage, the container comprising a plurality of wall panels which in the erected condition are joined together by joints, each wall panel being formed of a sheet material, and each wall panel including holding means, the holding means of each wall panel holding at least one vacuum insulation panel of the type described, which covers at least the greater part of the wall panel, such that in the erected container, the vacuum insulation panels of adjacent wall panels are positioned sufficiently closely together to restrict significant thermal leakage there between, and wherein at least some of the joints between adjacent wall panels are releasable to permit the adjacent wall panels to be moved away from each other to enable the container to be folded up into a flat pack.
  • Vacuum insulation panels of the kind described are compact, with excellent thermal characteristics, and are therefore preferred with the invention. However, the invention extends to other vacuum insulation panels as described above, which may be preferred in certain circumstances.
  • the invention provides a thermally insulative container, foldable to a flat pack for storage, the container comprising a plurality of wall panels which in the erected condition are joined together by joints, each wall panel being formed of a sheet material, and each wall panel including holding means, the holding means of each wall panel holding at least one insulation panel comprising a cellular material enclosed in an air tight envelope under vacuum conditions, which covers at least the greater part of the wall panel, such that in the erected container, the insulation panels of adjacent wall panels are positioned sufficiently closely together to restrict significant thermal leakage there between, and wherein at least some of the joints between adjacent wall panels are releasable to permit the adjacent wall panels to be moved away from each other to enable the container to be folded up into a flat pack.
  • the container in accordance with the invention provides a high degree of thermal insulation, and is not bulky in construction. It may therefore be used a a hand portable container in health care applications, for example. It can be folded into a flat pack by releasing joints between the wall panels.
  • the sheet material of the wall panels comprises a single piece of woven or continuous plastics material, which is moisture resistant and can therefore be wiped clean. When laid open flat, the sheet material is in the form of a cross, with the arms of the cross being formed by the wall panels. Where the sheet material is formed as a single piece, the joints between adjacent wall panels are formed by the flexible sheet material.
  • Free edges of the sheet material carry releasable joint means, such as Velcro tape, so that the free edges can be interconnected by the releasable joint means to form the erected container.
  • the sheet material may be formed of more than one piece, the separate pieces being interconnected along joint lines by further releasable joint means.
  • each wall panel is preferably held in a pocket formed of a pocket sheet of the same material as said flexible sheet material and sealed thereto along its edges, but leaving one edge free as an opening.
  • a flap may form a cover for the pocket opening.
  • the holding means may be of any desired type: for example, it may comprise straps for holding the vacuum insulation panel against said sheet material.
  • a preferred form of a hand portable thermally insulative container is shown in laid open condition and comprises a base wall panel 2, a top wall panel 4 and sidewall panels 6, 8, 10, 12.
  • the container In its laid open condition, the container is in the form of a cross or crucifix with side wall panels 8, 10, 12 forming three arms of the cross, and the longer fourth arm being formed by top wall panel 4, joined to base wall panel 2 via side wall panel 6.
  • the container is formed from a single piece of sheet material 14.
  • the material is a woven plastics material, such as nylon. This material is moisture resistant, and can be wiped clean of fluids and solid products for hygiene.
  • a pocket sheet 16 of the same type of material is secured to single piece 14 at each wall panel in order to provide a pocket 18.
  • the edges of the pocket sheet 16 are secured to the sheet 14 by welding or sewing and an open end of the pocket 18 has a cover flap 20 for covering the open pocket.
  • the pocket 18 covers essentially the whole extent of the respective panel, apart from a small external margin, as can be seen in Figure 2.
  • Side edges of wall panels 6, 10 and top wall panel 4 have edge flaps 24, each flap carrying a strip of Velcro tape 26.
  • top wall panel 4 has a top flap 28, which also carries a strip of Velcro tape 30.
  • strips of Velcro tape 32 are positioned on the underside of sheet material 14, as shown in Figures 1 and 2, for connecting with Velcro tape strips 26, 30.
  • the flaps 24, 28 and Velcro strips 26, 30, 32 provide releasable joints, and a means of assembling the container to the erected condition as shown in Figure 3, and then disassembling the container to the flat position shown in Figures 1 and 2.
  • Each pocket 18 contains a vacuum insulation panel 40 of the type described, as indicated in Figure 1, and formed of fumed silicon dioxide.
  • Each panel 40 fits closely within the respective pocket 18 so as to be held securely therein and is sealed inside by top cover flap 20, which has Velcro tape on its underside to connect with a further strip of Velcro tape along the top of the pocket.
  • the exterior of the container has carrying handles 50, a top cover securing clasp 52, pockets for identification information, etc.
  • the container as shown in Figure 1 may be folded up to a flap-pack condition, merely by folding the panels one upon the other. Alternatively, it may be preferred to take out one or all of the vacuum insulation panels of the type described before folding the container up to a flat-pack condition.
  • the sidewall panels 6, 8, 10, 12 are first folded upwardly about joint lines 22 to stand perpendicular to base panel 2. Flaps 24 are then folded over the sides of adjacent side panels as shown in Figure 3 so that the respective pieces of Velcro tape interconnect. These flaps of Velcro tape therefore form releasable joints between the respective sidewall panels.
  • the top wall panel 4 may then be folded down on top of the side wall panels and its side flaps and top flap 24, 28 may be folded over so that the strips of Velcro tape 26, 30 interconnect with Velcro strips 32 to form a totally sealed container, with the flaps 24, 28 forming releasable joints between all panels.
  • the sidewall panels are positioned so that the pockets 18 of panels 6 and 10 have their side edges abutting against the pocket edges of end panels 8, 12.
  • the lower edges of the pockets of wall panels 6, 8, 10, 12 abut against the upper pocket surface of base panel 2.
  • the upper pocket edges of the wall panels abut against the lower pocket surface of panel 4.
