Box for transporting samples

Abstract

The present invention relates to a box for transporting samples, conceived to maintain the temperature in its interior in a range between 15° C. and 25° C. for an extended time period and suitable for any product that requires thermal and mechanical resistance, particularly for biological samples. The transport box of the invention comprises a series of non-primary packaging of carefully selected dimensions, shape and materials, accumulating heat elements and, optionally, filling material.

1 . A transport box ( 1 ) for transporting biological products that comprises:
 a hermetic first non-primary packaging ( 2 ) manufactured from a high-capacity heat-insulating plastic material;   a second non-primary packaging ( 3 ) that contains the first non-primary packaging ( 2 ), manufactured from high-density polystyrene;   a third non-primary packaging ( 4 ) that contains the second non-primary packaging ( 3 ), to sustain the structure, increase thermal resistance and bear the labelling;   one or several heat accumulators ( 5 ) disposed in the interior of the first non-primary packaging ( 2 ) and/or between the first non-primary packaging ( 2 ) and the second non-primary packaging ( 3 );   
     characterized in that the relation (R μ ) between the volume of air between the first non-primary packaging ( 2 ) and the second non-primary packaging ( 3 ) and the total volume of the box is in a range between 0.1 and 0.6 and the thickness of the second non-primary packaging ( 3 ) is in a range between 4 and 6 cm. 
   
   
       2 . The transport box ( 1 ) for transporting biological products according to  claim 1 , characterized in that the first non-primary packaging ( 2 ) has an inner metal lining. 
   
   
       3 . The transport box ( 1 ) for transporting biological products according to  claim 1 , characterized in that the interior of the second non-primary packaging ( 3 ) is lined with a layer of heat-insulating material. 
   
   
       4 . The transport box ( 1 ) for transporting biological products according to  claim 1 , further comprising filling material, disposed in the interior of the first non-primary packaging ( 2 ), between the first non-primary packaging ( 2 ) and the second non-primary packaging ( 3 ), or in both. 
   
   
       5 . The transport box ( 1 ) for transporting biological products according to  claim 1 , characterized in that the second non-primary packaging ( 3 ) and the third non-primary packaging ( 4 ) are combined, forming a single packaging with a polystyrene interior and cardboard exterior. 
   
   
       6 . The transport box ( 1 ) for transporting biological products according to  claim 1 , characterized in that R μ  is in a range between 0.2 and 0.5. 
   
   
       7 . The transport box ( 1 ) for transporting biological products according to  claim 6 , characterized in that R μ  is in a range between 0.2 and 0.3. 
   
   
       8 . The transport box ( 1 ) for transporting biological products according to  claim 1 , characterized in that the thickness of the second non-primary packaging ( 3 ) is in a range between 4.5 and 5.5 cm. 
   
   
       9 . The transport box ( 1 ) for transporting biological products according to  claim 8 , characterized in that the thickness of the second non-primary packaging ( 3 ) is 5 cm. 
   
   
       10 . The transport box ( 1 ) for transporting biological products according to  claim 1 , characterized in that the first non-primary packaging ( 2 ) has a cylindrical shape. 
   
   
       11 . The transport box ( 1 ) for transporting biological products according to  claim 1 , characterized in that the second non-primary packaging ( 3 ) is a parallelepiped 30 cm in width×30 cm in length×20 cm in height. 
   
   
       12 . The transport box ( 1 ) for transporting biological products according to  claim 1 , characterized in that the second non-primary packaging ( 3 ) is a parallelepiped 40 cm in width×40 cm in length×30 in height.
