The coil has a cover closing the housings, where a user manually extracts the ice cream from a clearance opening in the housings. An independent claim is also included for an ice box for isolating ice creams.

Description

2890727 1

  The present invention relates to a device for temporarily isolating ambient heat and keeping cold between -1g C and o c Eskimos, ice cones, small ice cream jars and other ice creams released from a freezer.

  here we mean ice cream any finished product, sweetened and even salted iced or frozen based primarily on water or milk lover a specific form with or without packaging such as paper, cardboard or plastic etcetera.

  there are commercially available so-called low-temperature cold accumulators which release their latent cold energy at around -1 ° C, intended to be placed close to the ice creams in a cooler, but these accumulators are very inefficient because the the air in the cooler must be completely cooled in order to supply cold ice creams, a large insulating air space separating said ice creams from the accumulator. Because if it takes about 10 hours to recharge the battery in a freezer it will also take a long time for the cold passes from the accumulator ice cream in the cooler, time during which the cooler loses much of its energy cold.

  The device according to the invention overcomes this disadvantage. It consists according to a first characteristic: to achieve at least one cold accumulator reloaded said low temperature capable of containing the various ice creams in housings so as to surround them partially or totally by the accumulator (s) and to establish a close thermal contact between them and at least one accumulator, as well as a cold thermal barrier around them. it will be understood by close contact: either that the housing is the imprint of the ice cream, or that there is only a small volume of air and in any case a tiny air mass to cool between the cream iced and 3o its housing in cell. The accumulator containing the ice creams will be stored at -1 g C in a freezer. Thus the place taken in the freezer is more important than the place taken by the main packaging board of the 6 or 12 ice cones for example if it is frozen cones. At the exit of the freezer the ice creams at 1 ° C surrounded by an envelope at -1g C and additionally introduced into a cooler will be well protected from the ambient heat. So here we have a double insulation: in addition to the insulation by an insulating material of the polyurethane type of the cooler, the insulation by the cold envelope of the accumulators makes it possible to keep the ice creams at a temperature close to that of the Accumulators.

  Experimentation shows that one gains about 15 ° C in relation to refrigerated storage with a conventional low-temperature accumulator in a cooler.

  Gin cold accumulator said low temperature canAire consists of a sealed envelope containing a mixture of water and ethyl alcohol dosed so that the latent cold generated by the liquefaction of the frozen mixture is returned mainly at a temperature just above the temperature ice cream freezer output that is - 18 c. Advantageously, the ethyl alcohol water mixture used is non-toxic in the event of a puncture of the accumulator.

  according to particular embodiments: É Clearances can be provided opening into the housing, so that the user can manually extract the frozen crimes by pushing or pulling.

  É a cold accumulator may comprise at least one lid itself accumulator or not, fixed on itself and closing the housing. The role and advantage of the lid in addition to the fact that it isolates the ice cream is to prevent it from falling from their homes regardless of the position of the accumulator in the freezer.

  The accumulator may constitute the cover of another adjacent accumulator sliding on this other accumulator in a vertical plane in a cooler.

  E each cover can be engaged by elastic deformation on the accumulator or each cover is articulated on the accumulator, a zone of lesser thickness connecting the accumulator to the cover forming the articulation, opposite side to the articulation the cover is clipped on the accumulator in an elastic zone.

  É The slots in each accumulator may be ice cream imprints.

  A compact cooler containing at least one storage device can be placed in a freezer with at least one half-open insulating lid. It promotes the thermal conduction between the cold air of the freezer and a layer of air located between it and the accumulator or batteries, allowing the recharging of at least one accumulator. After refilling, it is possible to place the ice creams in the accumulator compartments and at least one accumulator in the icebox, the whole being put in the freezer. Thus we will not have at each consumption to dispose the accumulator (s) in the glacier. such a cooler can have two insulating lids offering ice creams in opposite directions.

  A cooler can isolate contain and immobilize at least one accumulator thanks to immobilizing inner slides. This will be particularly the case if it does not collect all of its accumulators, it may be the case in walk for a matter 1S weight. The slides are not necessary if it includes all its accumulators, because they lock each other.

  É The insulating cover of a glacier, especially when it is hinged to the boot, may be lined internally with a flat accumulator. Lined taken here in the sense of a garment textile lining.

  This accumulator closes at least one accumulator of the cooler when its insulating lid is closed. Thus when the user opens the cooler this lid accumulator is automatically removed and it has his hands free to grab the ice cream contained in the housing. This configuration will be very appreciable on the sand of a beach.

  The accompanying drawings illustrate the invention: Figure 1 shows in section and in top view several cold accumulators.

  Figures 2 to 6 show one and accumulators in a glacier.

  The figures) at j represent two adjacent accumulators in a cooler.

  Figure 10 shows a small cooler containing accumulators in a large cooler.

  Figures 11 to 14 show an embodiment of accumulator. Figures 15 to 20 show a glacier embodiment.

  With reference to these drawings: FIG. 1 shows several variants of the accumulator device able to contain ice-covered eskimos and cones, the cover (9) can be made of a simple plastic layer or be itself an accumulator. In any case it will prevent ice cream from falling into the freezer.

  In Figures 2 to 6 the plastic covers () are nested in the opening of the housing (3) (Figure 4), a single hole (Y) in these covers allows their extraction using the index. The accumulator (13) (board 2/6) housed in the inside of the ice cover, comes to the closure of the cooler, cap and completely imprison the ice creams in the accumulators.

  The figures y to j testify to the interest in making two accumulators head to tail, one constituting the lid of the other and vice versa. / l sut to extract the ice creams which are advantageously there also completely closed in the accumulators, draw the accumulators by the catches (1g) to slide in a vertical plane (35). Ice creams can then be extracted by the clearances (12). Note that in this embodiment the ice creams are small pots pressed and tight on the beads (33) of the housing (3).

  The advantage of 10 is a small cooler (1) containing ice cream in accumulators (2), itself in a large cooler (4) is to constitute a double insulation. In addition to walk or the beach we can put in the great ice around the small fresh produce in s -c. The large cooler (4) has a portion (5) immobilizing the small cooler (1).

  In the embodiment according to Figures 11 to 14 and in particular by constituting conical housings opening upwards and downwards in order to optimize the space, the accumulator is made in two parts (14) and (15). ) each made of plastic in a single injection molding operation, then assembled by thereto welding or ultrasonic welding. The tooling (16) serves to maintain and stiffen the assembly for the thermo welding operation, a pressure being chapped according to the arrow F. Guides (1y) for introduction into the cooler coming from molding in the workpiece ( 1-) also serve as reinforcements for rigidii er. Areas of oindre thickness (Io) are folded to 1go to form the lids. The inner void of the envelope thus formed is filled in the tenth by a mixture of water and ethyl alcohol (6) dosed at a little less than 1 g of alcohol via a hole which is then closed by a watertight stopper. plastic (g) as for any accumulator.

  In another non-illustrated embodiment of an accumulator (2) shown (plate 3/6) the envelope is directly and fully molded and blown internally in a single operation in the manner of a plastic bottle of mineral water . The envelope thus constituted is 1s filled and closed as above.

  In the embodiment of a cooler according to the board (6/6) a layer of air (25) between the cooler and the accumulator is achieved by means of 4 wedge slides (22) molded into the inner part (31). ) of the cooler. Three housings (j, 20, 21) for the projection (2y) of the cooler cover (24) respectively allow the open position, open and closed of the same lid, frustoconical pivots (2g) being housed in the hollow frustoconical (2j) upper flanks (sg) of said cooler. The cover (24) moves from one position to another by bending flanks (1g) when the user actuates this cover around the axis (2y). The trapezoidal sections of the housings, 20, 21) and the projection (2y) of the cover (24), trans forming a rotational movement in a spacing and flexing movement of the sidewalls (tg). Note that the release of housing, 20, .2) and the hollow (2j) is 3o facilitated by these trapezoidal shapes that spread the flanks (1g). The demolding being by deformation. The cooler itself will be constituted in a conventional manner: a piece (32) molded polyurethane trapped between two plastic moldings (26) and (31). For a better understanding of the diagrams: the cooler is represented without its insulating cover (f-figure 16), this one being drawn separately (figure 18 and 2o). according to an embodiment not shown the insulating cover (24) of this cooler can be doubled internally by a cold accumulator. Eskimos will be placed in their 6 dwellings with or without wrapping paper.

  For example, the parallelepipedic cooler will have dimensions of the order of 25 cm for the length, width for the width and 20 cm for the height of the accumulators, which are parallelepipedal. the cooler.

  The invention is particularly intended for the cold conditioning of ice creams during a picnic or the so prolonged tasting of these same ice creams in a garden and also in the vkaISOn.
