Description

The present invention relates to an ice-cream display cabinet. In particular, the invention relates to an ice cream display cabinet for an ice cream parlour, of the type suitable for holding and serving loose bulk ice-cream in tubs, for example a handmade ice-cream.
Two main types of display cabinets or counters for ice-creams are known in the art. One type is represented by the ice counters of the well type, in which the ice-cream is held into cylindrical containers with vertical development, placed in a refrigerated counter and provided with a lid. Another type is represented by the display windows of the “visible ice-cream” type, in which the ice-cream is contained in ice-cream tubs without a lid, arranged side by side in a refrigerated counter provided with a transparent display cabinet, in such a way that the consumer is attracted by the sight of the ice-cream.
Compared to well counters, the ice-cream display cabinets allow ice-cream to be served more quickly, both because the gelato flavours are clearly visible and attractive to the consumer, and because the operator does not need to open and close the tub lid, as in the case of the well. However, the ice-cream contained in the display cabinets provided with tubs without a lid is more subjected to temperature changes and is not stored in an optimal manner, as is the case in well counters. Moreover, since the tubs are arranged next to each other, it often happens that ice-cream residues infiltrate in the spaces between the counter and the tub and between each tub, thus causing mould and bacteria to proliferate.
In an inconvenient manner, moreover, in both types of ice-cream counter/display cabinet, the operator is forced to bend down several times to access the ice-cream well or tub to take ice-cream, assuming uncomfortable positions and working in a poorly ergonomic environment.
It is clear, therefore, that each of the aforementioned types ice-cream counter/display cabinet suffers from drawbacks linked to the reasons listed above.
One of the objects of the present invention is to provide an ice-cream display cabinet that is able to overcome the drawbacks of the ice-cream counters and display cabinets of the prior art, in such a way as to ensure an adequate preservation of the ice-cream and at the same time improve the ergonomics of the operator when serving the ice-cream, while maintaining the advantages of the ice-cream display cabinets of the prior art.
This object is achieved by an ice-cream display cabinet and an ice-cream drawer according to the appended independent claims. The dependent claims describe embodiment variations.

Innovatively, the ice-cream display cabinet according to the present invention, due to a vertical arrangement of the product and the presence of removable ice-cream tubs, eliminates the drawbacks of the ice-cream counters and cabinets of the prior art. In particular, the ice-cream display cabinet ensures an adequate preservation of the ice-cream and at the same time improves the ergonomics of the operator during the ice-cream service operation.
Advantageously, the vertical display of the product allows optimising the space and creating a greater visual communication with the consumer. The consumer is visually attracted by the view of the ice-cream which is shown vertically on horizontal and vertical rows, through the transparent display wall and tub. Moreover, the vertical arrangement of the tubs allows limiting the depth of the ice-cream display cabinet, allowing the installation thereof even in small places.
In an embodiment that is particularly advantageous and attractive for the consumer, the display wall 23 is transparent only in some regions (such as windows), at the ice-cream tubs 200, so as to focus attention.
Advantageously, the independent opening of individual ice-cream drawers facilitates the use of ice-cream, making it neat, clean and simple. Moreover, the vertical arrangement of the tubs and their convenient extractability inside and outside the refrigerable display cabinet allows the operator to serve the ice-cream in a more ergonomic manner, maintaining an upright position, without tiring and uncomfortable body movements.
Advantageously, due to the presence of an inner compartment of the cabinet that is completely closed, the ice-cream is preserved in an optimal manner. Moreover, the further presence of seals on the drawers and also on the display wall ensures the permanence of a refrigerated environment as much as possible controlled, limiting the dispersion of refrigerated air (and therefore energy consumption).
Furthermore, during the service step, when the ice-cream tub is taken from the inner compartment, the ice-cream tub is kept refrigerated by the refrigerable element arranged around the tub, which acts as a cold accumulator.
In an even more advantageous manner, the eutectic mixture contained in the refrigerable element ensures a better maintenance of the optimal temperature of the ice-cream when the ice-cream tub is taken.
Furthermore, the possibility of opening the refrigerable display cabinet on the side of the display wall by a simple rotation makes the inspection of the inner compartment for maintenance and cleaning easy.
It is clear that a man skilled in the art may make changes to the invention described above in order to meet incidental needs, all falling within the scope of protection defined in the following claims.
