Definitions
- the present invention relates to a packaging intended, for example, for the transport of vaccines, sera which must be kept at a constant temperature.
- US-A-4,294,079 describes a package intended to contain and transport frozen products and which comprises a box with an insulated lining and in the bottom of which is arranged an absorbent layer, while the upper part has a cavity containing a refrigerant.
- an insulating thickness Between the upper part and the frozen products is arranged an insulating thickness, a free space being provided between the upper part and the insulating thickness and holes being made in the upper part to communicate the cavity and the free space.
- the refrigerant sublimes in the free space and thus forms, above the insulating thickness, a cooling layer to maintain the products at the freezing temperature.
- the packaging keeps the products at a negative temperature, but when this is to maintain objects at a positive temperature, for example of the order of 3 ° C to 8 ° C, the use of dry ice poses many problems because the intense cold produced by this ice tends to lower the temperature beyond the freezing point which risks damaging the products.
- One of the aims of the present invention is, contrary to the object of patent US-A-4,294,079, to produce a packaging which makes it possible to maintain a positive temperature internally for a determined period of time while using dry ice. .
- the packaging according to the invention is of the type formed from a cardboard box with an insulated inner lining providing a housing intended to receive the objects to be transported and a cover for closing the housing, an insulated intermediate plate of expanded polystyrene being disposed and fitted in a sealed manner in the internal lining so as to provide, between the cover and said plate, a cavity intended to receive dry ice, said packaging being characterized in that the internal lining and the intermediate plate are made of polystyrene expanded with a percentage of closed cells of the order of 90% to 95%.
- the objects are not directly in contact with the dry ice, the cold of which dissipates gently in the housing through the thickness of the intermediate plate.
- the overpressure in the cavity which promotes a slow and controlled propagation of the cold through the intermediate plate.
- the lining, the cover and the intermediate plate are made of expanded polystyrene.
- the expanded polystyrene has a percentage of closed cells of the order of 90 to 95%.
- an intermediate plate with a thickness of 4 to 6 cm for a volume of the order of 60 dm3 of the housing whose walls of the lining have a thickness of the order of 3 to 7 cm, it is possible to obtain for a period greater than 48 hours, maintaining the temperature in the housing at a value of 5 ° C with variations of the order of 2 ° C.
- the lining has an internal shoulder, the intermediate plate comprising a recess so as to be slightly forced into the housing.
- the establishment of the intermediate plate ensures a sealed closure of the housing.
- the packaging shown comprises a cardboard box 1 of generally parallelepiped shape with a bottom 2, a side wall 3 and flaps 4 constituting the closure of the box.
- the lining provides a housing 6 intended to receive the objects to be transported.
- a shoulder 7 In the inner side wall of the lining is provided a shoulder 7, said wall extending up to a certain distance from the edge of the body 1 adjacent to the closure 4.
- the housing 6 is closed by a plate 10 made of the same material as the lining 5 and which has a recess 11 so as to have a part bearing on the shoulder 7 and a part slightly engaging in the housing 6.
- the intermediate plate 10 has a certain thickness, for example, of the order of 4 to 6 cm for a volume of the housing 6 of the order of 60 dm3, the thickness of the lining being of the order of 3 to 6 cm.
- the intermediate plate 10 has such dimensions that it engages slightly by force and thus the housing 6 is perfectly sealed.
- the lining 5 is closed by a cover 12 which is embedded by its edge 13 in the lining 5 and which has a rim 14 resting on the free end of said lining, the upper surface of the cover extending to the vicinity of folding the flaps 4.
- a cavity 15 is formed which is intended to be filled with dry ice 16.
- the temperature in the housing 6 could, for a period of time greater than 48 hours, be maintained at a value of 5 ° C. with variations of the order of 2 ° C.
- the intense cold produced by the dry ice only diffuses very slowly through the closure plate 10, which thus makes it possible to obtain a constant positive temperature.
