Description

Packaging and display cabinet for perishable products.

The subject of the present invention is packaging (or cases) and refrigerated furniture incorporating the packaging, allowing the transport, storage and exhibition, in particular at a point of sale, of perishable products such as food products, pharmaceutical products. such as vaccines, veterinary or photographic products such as dandruff, in particular.

The technical sector of the invention is that of the manufacture of refrigerated furniture.

It is known by international application WO 94/17698 (RENARD), a removable refrigerated cabinet which includes means for guiding and circulating fresh air, and means for distributing fresh air to exhibition plans or shelves. some products ; the piece of furniture comprises cladding panels made of a material such as cardboard, which cladding is part of a superstructure removably mounted on a base which comprises means for cooling air and for dynamic circulation of air, this that is to say in particular a heat exchanger and a fan at least. The object of the present invention is to provide improved refrigerated furniture.

We also know, from patent application EP 88107291 (GERVAIS DANONE) a container for presenting articles which must be kept at low temperature in sales premises. the container is formed like a folded carton with wall elements, and has a receptacle portion for a removable cooling member; the receptacle part is made as a gangway in the form of a band supporting the cooling unit, which can be placed on top of the open container; the evaporator of the cooling group is arranged on the underside of the gangway; the container is made of a composite of corrugated cardboard and a thermally insulating material such as synthetic foam. The disadvantage of the containers and apparatuses described in this document is that they are not able to allow a circulation of fresh air inside the container and consequently do not allow to keep exposed on a place of sale where the ambient temperature is for example of the order of 15 ° C to 35 ° C, perishable products to be kept at low temperature, that is to say generally at a temperature of the order of -20 ° C to + 5 ° C .

Furthermore, the relative drawback of refrigerated furniture described in the aforementioned international application lies in the need, in order to have the structure for displaying the products on the base comprising the air cooling group, to lift this structure above of the base, that is to say at a height which can reach several tens of centimeters above the ground, and to position it then to rest it on this base with a precise positioning.

This drawback acquires particular importance when the structure is used as transport packaging for the products to be exposed, and is therefore filled with said products when it must be placed on the base containing the air cooling and ventilation group; because of the mass of the structure filled with products, which can for example be of the order of a hundred kilos approximately, this manipulation requires in certain cases the use of a motorized handling machine, whose bulk may prove to be incompatible with the floor space available in certain stores, the operation of which can only be carried out by persons specially trained for this purpose; in addition, the need to lift the packaging filled with products can be the cause of accidents, in the event of a fall, and / or due to the high mass.
