(13) With reference to FIGS. 1, 2, and 9 to 11, a bundle of containers, in particular bottles, cans or the like, according to the present invention is indicated in its entirety with 1.

(14) As observable in FIGS. 1, 2, and 9 to 11, the bundle comprises a structure 2 for holding containers 3, provided with at least one base wall 4 intended to support a plurality of containers 3 and at least one lateral wall 5 which extends transversely, preferably perpendicularly, perimetrically from the base wall 4.

(15) According to the embodiment illustrated in FIGS. 1, 2, 6, and 9 to 11, the structure 2 for holding containers 3 is provided with four lateral walls 5 which extend perimetrically from the base wall 4 to define a concave box-shaped structure.

(16) The base wall 4 and the lateral walls 5 define a housing compartment 6 open at the upper part and intended to support the aforementioned containers 3.

(17) Advantageously, the housing compartment 6 is impermeable so as to be able to receive a predefined amount of coolant 1a (FIG. 1), liquid or solid, such as for example ice.

(18) The structure 2 for holding containers 3 is made of a single piece, optionally starting from a sheet 2a (FIGS. 3 to 5). Preferably, the sheet 2a is made of cardboard or a similar paper material, whose surface intended to define the housing compartment 6 is suitably made impermeable, preferably using one or more hydrophobic substances, such as for example paraffin, resins and/or the like.

(19) Alternatively, the sheet 2a for the formation of the structure 2 for holding containers 3, is plasticised or it is entirely made of a plastic rigid or semi-rigid impermeable material.

(20) As observable in FIGS. 3 to 5, the aforementioned sheet 2a has a plurality of bending lines 2b through which it is possible to form the structure 2 for holding containers 3, which may be fixed in the final position (FIGS. 1 and 2) through suitable gluing and/or welding points.

(21) As observable in the enlargement of FIG. 5, each bending line 2b is obtained through a section reduction which is obtained on the surface opposite to the surface relative to the housing compartment 6 impermeable, i.e. on the surface faced outwards.

(22) In addition it should be observed that the bending lines may also be obtained on the surface intended to define the housing compartment 6, i.e. on the surface faced inwards.

(23) Advantageously, the bending lines 2b are also treated and made impermeable, at least at the housing compartment 6, for preventing losses of coolant 1a during the utilisation of the bundle 1.

(24) The formation of the housing compartment 6 starting from the cardboard or plastic sheet 2a may be obtained around a group of containers 3 to be packaged (FIG. 6) or before the positioning of the same in the housing compartment 6.

(25) With the aim of ensuring optimal cooling of the containers 3 during the use of the bundle 1 and containment the overall volume of the coolant 1a used, the lateral walls 5 of the structure 2 for holding containers 3 extend vertically by at least one third of the height of the held containers 3, preferably by at least half of the height of the held containers 3, even more preferably by at least two thirds of the height of the containers 3.

(26) As observable in FIG. 2, the lateral walls 5 of the structure 2 for holding containers 3 may have different heights depending on the type of packaging or bundles to be obtained.

(27) As observable in FIGS. 1, 2 and 9 to 11, the bundle 1 comprises at least one wrapping 7 made of thermoretractable plastic material which wraps the structure 2 for holding containers 3 and the containers 3 arranged therein.

(28) The wrapping 7 adheres externally to the base wall 4, to the lateral walls 5 and to the upper part of at least one of the containers 3 arranged in the housing compartment 6.

(29) As observable in FIGS. 1 and 2, the wrapping 7 circumscribes, compacting, the structure 2 for holding containers 3 and the containers 3 arranged therein.

(30) In this case, the structure 2 for holding containers 3 has the purpose of providing an impermeable volume suitable to receive the coolant 1a to be used, while the wrapping 7 exclusively performs the structural function of the bundle 1, conferring shape and consistency to the same.

(31) Optionally, the bundle 1 is provided with sealing means 2c, indicated by a dashed line in FIGS. 1 to 3 and 6, interposed between the structure 2 for holding containers 3 and the wrapping 7 for preventing the leakage of the coolant 1a from the housing compartment 6 along the lateral walls 5.

(32) As observable in FIGS. 1 to 3 and 6, the sealing means 2c develop externally on the structure 2 for holding containers 3 along the entire perimeter development of the housing compartment 6. In other words, the sealing means 2c develop along all the lateral walls 5 of the structure 2 for holding containers 3 parallel to the base wall 4.

(33) More in detail, the sealing means 2c comprise at least one layer in a sealing material, such as for example, glue, resin, rubber and/or the like, which is applied substantially perimetrically, optionally peripherally, on the surface of the sheet 2a intended to face towards to the outside.

(34) As observable in FIG. 3, the layer of sealing material of the sealing means 2c is advantageously applied also at angle areas 2d (FIGS. 3 and 6) of the sheet 2a, so as to contribute or even replace the gluing and/or welding points which guarantee the stability of the formed structure 2 for holding containers 3.

(35) According to a further advantageous aspect of the present invention, the sealing material of the sealing means 2c is adapted to be welded or joined to the wrapping 7 of the bundle 1 following an activation operation, which can be of the mechanical type, such as for example pressing or adhesion, or of thermal type, such as for example heating, or of the chemical type following one or more chemical reactions.

(36) The provision of the sealing means 2c considerably increases the overall and impermeable volume of the housing compartment 6 which is thus defined both by the structure 2 for holding containers 3 and the wrapping 7 wrapped around it.

(37) Advantageously, the wrapping 7 is provided with at least one access opening 8, optionally a plurality, for the introduction of the liquid and/or solid coolant 1a into the housing compartment 6 of the structure 2 for holding containers 3.

(38) Each access opening 8 is defined by at least one structural weakening line 7a which is obtained directly in the wrapping 7, advantageously by drilling or cutting the wrapping itself. The structure of the wrapping 7 may thus be broken and/or torn to allow the formation of the respective access opening 8.

(39) Advantageously, the bundle 1 provides for suitable closing means (not represented), optionally of adhesive type, for closing the access opening 8.

(40) Alternatively, the closing means may be obtained directly on the wrapping 7 so that the structure strip removed therefrom following the breaking of the weakening line 7a may be used for closing the access opening 8 defined.

(41) The bundle may also be provided with a gripping handle 9 which provides for respective adhesive portions 9a externally engaged on opposite parts of the wrapping 7 and a non-adhesive gripping portion 9b which lies astride the upper area of the wrapping 7.

(42) As observable in FIGS. 7 and 8, it is possible to provide for the presence of suitable spacer means 10 which can be introduced into the housing compartment 6 of the respective bundle 1 (FIG. 9) for spacing at least two adjacent containers 3 and define between the latter at least one interspace suitable for receiving the coolant 1a.

(43) The spacer means 10 comprise at least one grid 11 having a substantially network-like structure which delimits a plurality of housing seats 12 for the engagement of a respective container 3 and a plurality of cavities 13, each interposed between at least two adjacent housing seats 12.

(44) Advantageously, as illustrated in FIG. 8, each housing seat 12 has a substantially circular-shaped or circle arc-shaped profile, optionally smooth and/or continuous, in particular counter-shaped with respect to the profile, in transverse section, of the container 3 to be received.

(45) According to a further advantageous aspect of the present invention, illustrated in FIG. 7, each housing seat 12 has a notched profile which develops in a substantially circular or circle arc manner.

(46) Preferably, the notching of each housing seat is elastically yieldable to allow the interference fit of a respective container 3 to be received and simultaneous ensure the engagement of the same in the respective housing seat 12.

(47) Still with reference to FIGS. 7 to 9, wherein each cavity 13 has a substantially rhombus or triangular-shaped profile.

(48) According to the embodiment illustrated in FIGS. 10 and 11, the bundle 1 comprises at least one lifting element 3a, preferably a plurality of lifting elements 3a, arranged inside the housing compartment 6 for maintaining the wrapping 7 raised with respect to the containers 3.

(49) Advantageously, each lifting element 3a comprises an auxiliary container (indicated with bold letters in FIG. 11) which has a greater height with respect to the height of the containers 3 (represented with a fine line in FIG. 11) so that the wrapping 7 engages at the upper part the auxiliary containers delimiting with the latter and the containers 3 an upper chamber 14 for housing the coolant 1a.

(50) The bundle described above overcomes the problems observed in the prior art and attains important advantages.

(51) First of all, the provision of a structure 2 for holding containers 3 impermeable allows the introduction of ice or a coolant liquid 1a inside the bundle so as to be able to cool the containers present therein without having to remove the same from the respective packaging.

(52) The presence of the impermeable container 3 holder structure 2 also allows to contain the volume of water which is formed following the melting of the ice introduced into the bundle.

(53) The bundle according to the present invention is thus transformed into an ice holder container which can be used in a simple and practical manner by anyone during any outdoor or social events by providing the access openings required for the introduction of ice or coolant liquid which is easily introduced from above by gravity.

(54) Thus, the bundle described above allows to avoid the use of bulky ice containers into which bottles and/or cans are introduced after being removed from the bundles.
