Definitions

• the present invention relates to a device for receiving and transporting at least one tray containing a food product, in particular intended to be kept at a temperature below room temperature, such as ice cream. It also aims a freezer adapted to receive such a device.
• This device is intended to present, serve, isolate temporarily ambient heat, and possibly replenish the cold content of ice cream trays trade and stiffen the trays.
• Ice cream here means any finished food product sweetened or even salted and frozen mainly based on water or milk. These trays can be taken out of a domestic freezer but also kept inside the freezer.
• the trays are released one by one from the freezer and, it is not very easy to extract ice cream balls with a spoon because it is difficult to immobilize the trays.
• the trays are thin and sharp for the fingers. This is particularly aggravated by the fact that the trays manufacturers do not generally want to produce them in a plastic too thick since these trays are used only once. It is also not very practical to have to put them back in a freezer as soon as possible, even leaving them a little later for a new consumption. It is also not hygienic to leave these trays on a table because their contents should not be refrozen after thawing. During the summer, when it is very hot, it is sometimes difficult to bring ice creams from the cold aisle of a supermarket, even in an insulated bag, without melting them.
• An object of the present invention is thus to propose a device designed _

• These holding means can be made by implementing a means for clamping and strangling the tray under a flange often equipping the trays.
• Each tray can be belted under its collar to immobilize it in all directions, so that the extraction of ice cream by means of a spoon does not lift the tray. The collar then serves as a stop.
• a device comprising a housing that promotes buckling of the flat portions of the tray outwards rather than inwards. It is possible to initiate an outward buckling by producing a slightly ovalized impression.
• the immobilization of a tray can be strengthened by throttling and clamping thereof in a portion of the housing which is the imprint of the specific shape of the tray. This clamping can be achieved at a collar often equipping the trays and which comes to be in abutment on the upper face of the enclosure when a user drives a tray into a housing.
• the edge of the housing in the upper part of the enclosure is elastic and dimensioned slightly smaller than the portion of a tray located just under the collar.

Then simply put the lid on the other tray, perform a half-turn 180 ° and extract the ice cream from the other tray. This provides a particularly comfortable position for the supporting hand.
• the third lid may not have a label, to avoid any risk of confusion on the types of ice cream stored.
