Description

The present invention relates to a portable refrigerant isothermal box.

  This box is generally used to receive, refrigerate and maintain fresh all types of liquids and in particular drinks contained in flexible containers or in plastic bottles for withdrawal of drinks.

  Portable boxes receiving drinks contained in flexible containers or in plastic bottles with a tap for withdrawing beverages are well known in the prior art.

  Some examples of this type of caissons are disclosed in patents US 2003/0029187, US 6,193,097 or US 5,231,850. These documents disclose complex refrigeration devices where the contribution of cold is by the addition of ice, gel or cooling plates inside said box.

  However, none of the existing solutions mentioned above relates to portable boxes receiving drinks contained in flexible containers provided with a withdrawal means. Indeed, adapting these refrigeration devices to this type of box would be to complicate the design and assembly.

  The object of the present invention is therefore to provide a portable box receiving liquids that can be withdrawn, to cool and keep fresh these liquids and in particular drinks, having a refrigeration device of simple design facilitating the assembly of the various elements and being able to keep the cold for several days.

  The object of the invention is a portable refrigerant isothermal box comprising a parallelepiped box containing a container containing a liquid, said container being provided with a liquid withdrawal device 2860861 -2 that can exit out of said box through a wall , a layer of insulating material covering the inner walls of said box and a refrigeration device comprising a plurality of cooling plates arranged inside said box, characterized in that said plates are identical and square. This characteristic implies that the order of mounting plates in the cavity does not matter, which simplifies the design and facilitates the mounting of the box.

  Other features and advantages of the invention will be better understood on reading the description which follows, of a preferred embodiment and with reference to the appended drawings showing a mode of execution given by way of non-standard example. limiting.

  Figure 1 shows a perspective view of the box open from below.

  Figure 2 shows the vertical sectional view along A-A of the box.

  FIG. 3 represents the horizontal sectional view along B-B of the box. FIG. 4 represents another vertical sectional view along C-C of the box without the container containing the liquid.

  Figure 5 shows the horizontal sectional view along B-B of the box without the container containing the liquid or the refrigerant plates are shown. This figure illustrates a preferred embodiment of the housing of the refrigerant plates.

  The figures show a portable refrigerant isothermal box comprising a parallelepipedic box 1, preferably made of rigid ribbed corrugated cardboard with pre-cut transport handles 2.

  The inner side walls and the inner upper wall of the box 1 are covered with a layer of insulating material 3 as illustrated in Figures 2 to 4. This material is preferably polystyrene.

  This box comprises a removable lower part 4, for inserting or removing the various constituent elements and in particular the cooling plates, as shown by way of example 1.

  2860861 -3 This removable lower part, once in the closed position, closes the opening 10. There is then an isothermal box having a cavity 5.

  The cavity 5 is intended to receive a container 6 containing a liquid 7 and the refrigeration device. This container may be flexible, of the type in addition, or be a plastic bottle. In a well known manner, the container 6 is provided with a withdrawal means consisting of a retractable tap 8 that can exit out of the inner part of the box by means of a pre-cutout 9 on the outer face of one of the walls 11 of said box and a conduit 12 passing through this wall.

  The refrigeration device is constituted by four refrigerating plates 13, 14, 15 and 16 placed inside the box. These refrigerating plates are of the type that are usually placed in a domestic freezer or a refrigerator freezer for a few hours and then stored in the insulated box to cool and keep fresh the liquid in the container 6. These Cooling plates contain a coolant capable of maintaining a temperature of approximately 10 Celsius for at least forty-eight hours, regardless of the type of beverage and for an outside temperature of around 30 Celsius.

  These plates have the distinction of being identical and parallelepiped of square section. The positioning direction of the plates does not matter.

  Figures 2 to 4 show an example of design and arrangement of these refrigerant plates. Three side cooling plates 13, 15 and 16 are arranged on the three inner side walls of the box other than the one through which the retractable cock 8 passes.

  The square-shaped faces of the plates are preferably oriented towards the inside of the cavity 5 so that the surface of cold plates in contact with the container 6 is maximum. The transfer of frigories from the plates to the liquid 7 is thus optimal.

  2860861 -4 The refrigerant plate 16 is located in the middle of the inner side wall opposite the wall 11 from which the valve 8 comes out. This cooling plate is wedged in a housing 17 of complementary shape as shown in FIG.

  This housing 17 has the particularity of forming two perpendicular vertical wall projections 20, located on either side of said groove. The presence of these two projections serves to form two further housing 18 and 19 on the other two inner side walls of the box. The refrigerant plates 13 and 15 are wedged respectively in these two further housing 18 and 19 of complementary shape. The presence of the two projections 20 is finally used to form the three housings 17, 18 and 19 in which any of the cooling plates can be wedged. This simple design therefore allows easy assembly of the constituent elements of the box.

  According to a preferred embodiment of the invention, it is shown that the removable lower part 4 has on its upper face 21 a housing 22 of complementary shape for wedging the bottom cooling plate. 14 remaining. Two other housings 23 are provided to allow the interlocking of this removable lower part 4 in the two vertical projections 20.

  The removable lower part 4 is coated with an insulating material 24 on its upper face 21 facing the inside of the cavity 5. The opposite face 25 of said removable lower part 4 may be coated with the same insulating material 24 or corrugated board rigid rib or any other material useful in the design of said box. The insulating material 24 is of the same nature as the insulating material which covers the inner side walls and the upper inner wall of the box 1. This material is preferably polystyrene.

  Once the three refrigerated side plates 13, 15 and 16 wedged and the container 6 introduced, fits the lower removable part 4 in which is housed the bottom refrigerant plate 14. This removable lower part then comes to wedge like a nestable bottom for plug the opening 10 and hold in place the side refrigerant plates. The portable coolant isotherm box is thus obtained object of the invention This box can be used to receive, refrigerate and keep fresh drinks to be consumed fresh such as water and some wines. By placing the cooled cooling plates in the box object of the invention, the user has for several days a cool drink without the need to place it in the refrigerator.
