Definitions

  • the present invention refers to a thermally insulated container, mainly intended for storing and transporting material such as vaccine, biological material and the like, requiring a substantial constant temperature during a time of several months.
  • GB-A-1,006,746 discloses a container for transport of material which requires cooling by means of a gas in liquid state.
  • the container comprises an insulating external container in which a porous container body is located and in the interior of which the material, which should be cooled can be introduced.
  • the container body is prepared with slowly boiling liquid gas which slowly evaporates whereby cold is emitted.
  • This invention is primarily intended for biological material which should be kept at a very low temperature, well below the freezing point, and which therefore requires a liquid gas for its cooling.
  • the device is furthermore designed to allow the gas generated during the boiling to escape through evacuation canals.
  • the cooling device is primarily intended to be used during measurement inside tunnel owens and the like, and it comprises mainly an inner and outer cylinder located in an insulated container. Between the inner and outer cylinder there is arranged a heat-storing material which communicates with the surroundings via a steam exhaust tube and a filling tube. The inner device is again located in an insulated container filled with insulating material. This invention is thus intended for very high surrounding temperatures, which occur e.g. in owens.
  • a heat storing material which when exposed to heat evaporates to steam which escapes through a relief tube.
  • the device is position sensitive, e.g. it must always be located in a certain way there the filling tube and the tube for evacuation of steam is directed upwards, in order to work. It is only intended to maintain a certain temperature in its inner space during a short period of time.
  • the DE-A-2.411.960 discloses a casing for frozen products.
  • the casing consists of double walls with a cold accumulating material therebetween, the state of aggregate of which is changed close to the storing temperature of the product.
  • This casing is intended only for short time storing, e.g. one or a few days at most.
  • the US-A-3.810.367 refers to a cooling and storing container comprising an inner compartment holding the material to be cooled and an outer compartment holding heat absorbing material (ice and water). The two compartments are surrounded by walls and lids of heat insulating material. This container is also only adapted for short-time cooling and storing (several hours is mentioned).
  • the purpose of the present invention is to provide a thermally insulated container which can be used as a disposable container and which is cheap to manufacture.
  • Another purpose of the invention is that the container should be robust and protect its contents against damages caused by external influence in the form of impact and blows.
  • a further purpose is that the material to be stored and transported shall be kept at a substantially constant temperature during a time of several months.
  • the container should use a passive system, e.g. no external energy should be supplied to maintain the determined temperature. By means of a container according to the invention it should be possible to neglect the transport time, e.g. it should be possible to transport the container by boat instead of using airfreight which makes the transport cheaper.
  • a container comprising an outer and an inner casing each of which is hermetically sealed, the material is arranged inside the inner casing; a solid-to-liquid phase transforming refrigerant material, e.g. ice or brine is arranged in said inner casing surrounding said material; an insulation is filling the space between said inner and outer casing and comprises a porous material under vacuum, which encloses said inner casing on all sides; the space between said inner and outer casing is free from structural connections extending between said inner and outer casings.
  • a solid-to-liquid phase transforming refrigerant material e.g. ice or brine
  • FIG 1 a thermally insulated container according to the invention. It consists of an outer casing 1 made e.g. of plastic material and it is designed as a square box in order to facilitate stacking and storing.
  • the size of the outer casing can of course be varied within wide margins but can e.g. be about 50x50x50 cm.
  • a container of this dimension has a transport weight of about 15-20 kg.
  • an inner casing 2 In the space inside the outer casing there is located an inner casing 2 at a certain distance from the outer casing 1. Also this inner casing 2 may consist of plastic or similar material.
  • the outer and inner casing 1, 2 are designed to be diffusion proof in order to reduce the pressure increase and to maintain a low heat conductivity.
  • an insulating layer 3 which space preferably can be filled with an insulating, porous material, e,g. perlite.
  • an insulating, porous material e.g. perlite.
  • this space has been put under vacuum by evacuation. This may e.g. be achieved thereby, that crosslinked polythylene is used.
  • the outer and the inner casing are sealed e.g. by a plastic weld after packing of the material, the cooling object 4, which should be transported or stored.
  • the material, the cooled object, which shall be stored and/or transported at a constant temperature, is located in the intermediate space of the inner box shaped casing 1.
  • the material which can consist of a daily ration of vaccine, e.g. about 1-2 kg can be enclosed in a further box of plastic or similar material or it may simply be enclosed in shrink film 7 (see fig. 2).
  • the space between the package 6, of the cooled object and the inside of the inner casing 2 is filled with a phase transforming material 5, which e.g. can be brine or ice of distilled water. If ice is used as phase transforming material, vaccine of the above mentioned quantity, can be kept cooled during a very long time. Calculations and practical tests have shown that the cooled object can be kept at a temperature just above 0°C during 180 days. When the phase transforming material has been completely transformed to its other, warm, phase, the temperature in the container however will increase rapidly.
  • phase transforming material will not transform to gases.
  • phase transforming material such as ice water or salt impacts and blows are effectively absorbed whereby the cooled object is well protected during the transport.
  • FIG 2 is shown an alternative embodiment according to the invention.
  • the cooled object 4 has been packed by means of shrink film 7 only and put into the inner space 5 of the inner casing 2.
  • the cooled object is located together with the phase transforming material in the inner casing.
  • Around this inner casing a number of e.g. 20, insulating layers are arranged.
  • the insulating layers can e.g. consist of layers of porous glass fibres and heat-reflecting aluminium foil. It is important at the application that the insulating layers fit tightly around the inner container and that no thermal bridges are formed in possible joints.
  • the metal container and insulation layers are thereafter located in an outer, e.g. cylindric container, which could be provided with a reinforcement at the inside, and the outer container is vacuum evacuated.
  • Both the inner and outer container may consist of a container of the type of tin can, which makes the transport container cheap to manufacture as earlier already known technology may be used.
  • the container is exposed to direct sunlight or other heat radiation it is appropriate to provide the outer surface of the container with a reflecting layer 11, e.g. in the form of metal film.
