Description

The present invention relates to packaging intended in particular for the transport of

frozen infectious substances.

  The object of the invention is in particular to produce a packaging intended to keep containers containing infectious substances frozen under requisite cold conditions, the packaging being lighter and impact resistant. The packaging according to the invention is of the type comprising a box of generally parallelepiped shape, an insulated lining intended to be housed in the box and to be filled with a refrigerant, said lining being

  formed of two half-shells intended to contain at least one container containing the infectious substance to be carried, each half-shell having four side walls and the bottom, and is characterized in that it comprises a sleeve s inserting between the half-shells, said man-

  chon having a height such that it extends to the vicinity of the bottoms of said two half-shells and being made of an isothermal material, the internal surface of said sleeve being reflective.

  Thanks to such an arrangement, the sleeve forms, in the half-shells, a doubling which increases the qua-

  isothermal beds, said sleeve forming a receptacle which makes it possible to fill the entire volume delimited by the half-shells of a refrigerant such as dry ice.

  In order to improve the impact resistance qualities of the packaging, the bottom of each half-shell

  includes a shock absorbing pad. 30 Preferably, each shock absorbing pad has at least one blind hole corresponding to the location.

  ment of the container to be transported. According to a constructive detail, each shock absorbing pad comprises a series of blind holes adjacent to each other, the parts cut out to make 2 said holes being held in them. Thus when using the packaging, the bor holes are released. - nes necessary to receive the containers by removing the corresponding cut parts. Preferably, the shock absorbing pads are made of a cellular plastic material with closed cells. The half-shells can be made in

polyurethane foam.

  Finally, the sleeve can be made of polys-

compressed tyrene.

  The invention will now be described in more detail with reference to an embodiment.

  particular given by way of example only and shown in the accompanying drawings, in which: Figure 1 is an exploded perspective view of a package according to the invention.

  Figure 2 is a sectional view through a vertical plane of the packaging of Figure 1 mounted.

  Figure 3 is a perspective view of a

tail.

  The packaging, shown in the figures, comprises a box 1, preferably made of cardboard, with flaps 2.

  In the box, are housed two half-shells

  3 and 4 which constitute an insulated lining.

  The half-shells 3 and 4 are identical, the half-shell 3 having a bottom 5 and four side walls

  rails 6, 7, 8 and 9. A shock absorbing pad 10 is applied against the bottom 5 which has three circular blind holes

11, 12 and 13.

  The damping pad 10 is made of a flexible and elastic plastic material, preferably a cellular plastic material with closed cells. The circular blind holes 11, 12, 13 are

  practiced so that the axes are located on the same straight line and that they are intersecting, the parts uncovered

  pla lla, 12 a and 13 a, to form the blind holes, being kept in the latter At the time of use, if two bottles are to be shipped, the cut parts lla and 13 a are removed, on the other hand if only one bottle is to be shipped, only part 12 a is removed (see Figure 3).

  The half-shell 4 has four side walls 15, 16, 17 and 18 and a bottom 19, against which is

  applied a shock absorbing pad with the same 35 blind holes as pad 10.

  In the half-shells 3 and 4 is inserted a sleeve whose height is such that it extends between the pads 10 and 10 a Said sleeve cooperating with the side walls of the two half-shells. 5 The half-shells 3 and 4 can be made, for example, of expanded polystyrene, of foam

  polyurethane or other. The sleeve 20 can be made of compressed polystyrene, its internal face being reflective.

  As seen in Figure 2, bottles to be transported are placed in the blind holes 11 and 13 of the pad 10 of the half-shell 3, the sleeve 20 being put in place, the space between the bottles 25 is filled with a

  refrigerant such as dry ice, then the half-shell 4 is put in place, the half-shells 3 and 4 being placed in the box 1.

  The sleeve 20 makes it possible to fill the entire internal volume of the half-shells 3 and 4 with dry ice.

  and the internal reflecting surface avoids the loss of cold.

  The bottles 25 are intended to contain

  test tubes wound in layers of fabric to protect them, these test tubes containing -

  frozen faults. 25 The packaging thus produced is very impact resistant, light in weight and perfectly insulated.

  Of course, the invention is not limited to the embodiment which has just been described and shown.

  Many modifications of detail can be made there without departing from the scope of the invention.
