  • An example is a transportation of vaccines to remote areas.
  • Immunization programs have been using insulated containers as vaccine carriers for decades. Typically, the last-mile transport of vaccines is made by humans walking or on motorbikes carrying the insulated container.
  • the temperature range at which decay of most pharmaceutical compounds is the lowest is typically +2°C ... +8°C.
  • both the exceedance of the upper temperature limit and a shortfall of the temperature to below the lower limit in the vaccine carrier causes vaccine waste and reduces the number of humans vaccinated.
  • An object of the present invention to provide a thermally insu- lated transport box so as to overcome the above problems.
  • the objects of the invention are achieved by a thermally insulated transport box which is characterized by what is stated in the independent claims.

  • the outer surface of the ther- mally insulated transport box 1 can also be painted with a heat reflective paint in order to reduce ambient heat load.
  • a coating can be applied to the outer surface of the thermally insulated transport box 1 to prevent the box from denting and scratching. The coating can also reduce ambient heat load by reflecting.
  • an antimicrobial coating can be applied to the interior face or/and the outer surface of the thermally insulated transport box.
  • perishable foodstuffs may temporarily be sold and stored in an isolated container containing a lid closing the container when the container includes a cold accumulator, or even without a cold accumulator if the storage temperature re- mains below a legal maximum due to the existing ambient temperature.
  • Perishable foods are those likely to spoil, decay or become unsafe to consume if not kept at chill temperatures below a legal maximum. Examples of perishable foods are meat, poultry, fish and dairy products. Typical legal maximum temperature for perishable foods is 0-8°C.
  • the thermally insulated transport box 1 of the can be used for temporary storing of perishable foodstuffs.
  • the phase change material has a melting temperature at a temperature range -2°C ... 2°C.

Abstract

La présente invention concerne une boîte de transport isolée thermiquement (1) qui comprend un couvercle (2) et un corps de boîte (3). Le corps de boîte (3) comprend des parois latérales (4), des parois d'extrémité (5), une ouverture (6) et une paroi inférieure (7). Les surfaces internes des parois latérales (4) comprennent des demi-colonnes (9a) faisant saillie à partir de la paroi latérale (4), les surfaces internes des parois d'extrémité (5) comprennent des demi-colonnes (9b) faisant saillie à partir de la paroi d'extrémité (5), et les demi-colonnes (9a-b) s'étendent verticalement le long des parois latérales (4) et le long des parois d'extrémité (5). La boîte comprend au moins une cloison de séparation (11) comprenant des encoches (12) dans ses bords opposés (13), et comme la cloison de séparation (11) est positionnée pour recouvrir au moins une partie de l'ouverture (6), elle (11) est supportée par les demi-colonnes (9a) et au moins une partie des encoches s'alignent avec des espaces entre les demi-colonnes (9a) faisant saillie à partir de la paroi latérale (4) pour former un trajet d'écoulement d'air.
