Definitions

  • the present invention concerns an isothermal pack to contain and preserve, at a suitable temperature and for a determinate period of time, a cold food product, such as for example an ice cream or suchlike.
  • a cold food product such as for example an ice cream or suchlike.
  • the present invention concerns a pack suitable to preserve the ice cream when the latter has to be transported for a relatively short distance without any specific refrigeration members, for example when it is purchased "to go", and taken from the shop to the place where it will be eaten.
  • Isothermal packs are known, for containing and preserving a cold food product, such as for example an ice cream or suchlike, when it is transported without specific refrigeration members such as for example refrigeration circuits, ventilators, freezers, conditioners or other.
  • Known packs generally comprise a first container, or insulating tub, with a relative lid, having a thickness of several millimeters and made of expanded polystyrene, and a second container, or containing tub to contain the ice cream, made of plastic material for foodstuffs, arranged inside the first tub and having a thickness of some tenths of a millimeter.
  • a protective sheet made of shiny paper is also arranged on the upper outer surface of the ice cream.
  • the insulating tub and the containing tub are rigid and have to have corresponding shape and size, thus entailing an increase both in the production costs and also in the bulk of the tubs when they are stored during the wholesale distribution steps.
  • tubs are specific for containing and preserving ice cream, and are normally of the throw-away type. This disadvantage makes it impossible for the final user to re-use the tubs effectively, for example to contain other foodstuffs or products, even other than food.
  • One purpose of the present invention is to achieve an isothermal pack for cold food products which will allow to maintain the latter at a substantially constant temperature for a period of time longer than that allowed by known packs.
  • Another purpose of the present invention is to achieve an isothermal pack which is simple and economical to make, and which requires limited space for storage at least during the steps of wholesale distribution.
  • Another purpose of the present invention is to achieve an isothermal pack which can be re-used effectively to contain other foodstuffs or, more generally, other goods, not necessarily foodstuffs.
  • Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.
  • an isothermal pack according to the present invention is able to contain and preserve, at a suitable temperature and for a determinate period of time, a quantity of a cold food product.
  • the pack according to the invention comprises a first container having insulating properties, and a second container able to be arranged inside the first insulating container, and to contain the cold food product.
  • the first container is made of paper material, such as for example cardboard, pasteboard or suchlike, and is shaped so as to define a box-like structure.
  • the second container comprises a containing shell made of plastic material for foodstuffs defining inside a containing compartment for the cold food product.
  • the box-like structure is formed by a shaped sheet having a unitary thickness in the order of millimeters, folded over itself, while the containing shell comprises a first lower half-shell and a second upper half-shell having a thickness in the order of tenths of a millimeter, and able to be selectively coupled with each other.
  • the shaped sheet that makes up the box-like structure is advantageously made of corrugated or honey-combed cardboard which, having good isothermal characteristics, allows to maintain, inside the box-like structure which it forms, the temperature necessary for the correct preservation of the food product contained in the pack.
  • the conformation of the shaped sheet allows, in its folded condition, to have at least one wall of the box-like structure with a double thickness with respect to the unitary value of the thickness of the original shaped sheet, so as to further increase the thermal seal of the box-like structure.
  • the shaped sheet is made and folded so that all the walls of the box-like structure have a double thickness with respect to the thickness of unitary value.
  • an isothermal pack is achieved to contain and preserve a cold food product in a simple manner and using low-cost materials that can easily be found, in any case ensuring an optimum cold seal and hence a good preservation of the cold product contained therein.
  • Applicant has found that, given the same external temperature, and with the same quantity of cold food product contained, for example of ice cream, in a time varying from about 30 minutes to about 60 minutes, which is the time used on average by the user to transport the ice cream, the cold seal of the packs according to the present invention, during the 60 minutes, is substantially comparable with that of known packs, and even considerably more if only the first 30 minutes are considered. More specifically, Applicant has found that the isothermal pack according to the present invention, starting from an inner temperature of -15°C and with an external temperature of 38°C, loses less than 1°C in the first half hour, while known packs can lose, in some cases, even about 2°C.
  • the containing shell comprises a transverse perimeter zone of a size corresponding with the inner transverse size of the box-like structure, in order to prevent the second container from moving transversely inside the first container when the isothermal pack is transported.
  • the bottom wall of the containing shell is shaped so as to contact the inner lower surface of the box-like structure with a minimum surface, for example by means of a supporting frame, a plurality of feet or other, so as to further reduce the possibility of dissipating the internal temperature.
  • the box-like structure being formed by a shaped sheet folded over itself, not only has limited production costs but also considerably reduced bulk upon storage, since it can be transported and distributed wholesale in its flat condition, and folded only a few moments before accommodating the containing shell inside it.
  • a further advantage of the present invention is that, since it can be selectively closed and removed from the box-like structure, the containing shell can be re-used effectively to contain other cold food products, or other foodstuffs or, more generally, other goods, not necessarily food.
  • the containing shell can be removed also allows to replace it individually inside a refrigerator, or another refrigeration apparatus, if the cold food product is particularly melted, for example due to the pack accidentally remaining in the rays of the sun for a period much longer than 60 minutes.
  • the food product contained is cooled and frozen instantaneously, since the containing shell has low isothermal properties, whereas in known packs the cold food product, which remains inside the insulating tub, has a substantial thermal hysteresis before cooling.
  • an isothermal pack 10 is able to contain a cold food product, in this case ice cream, and to preserve it at a determinate temperature, for example less than 0°C, advantageously from -15°C to -9°C, when it is transported without specific refrigeration members.
  • the isothermal pack 10 comprises a first container 11 and a second container 12, the latter able to contain the ice cream and able to be selectively positioned inside the first container 11.
  • the first container 11 in this case comprises a shaped sheet 13 made of corrugated or honey-combed cardboard (fig. 3) folded over itself (figs. 1 and 2) and constrained by means of substantially known constraint systems in a determinate configuration, so as to define a box-like structure 15 shaped substantially like a parallelepiped.
  • a shaped sheet 13 made of corrugated or honey-combed cardboard (fig. 3) folded over itself (figs. 1 and 2) and constrained by means of substantially known constraint systems in a determinate configuration, so as to define a box-like structure 15 shaped substantially like a parallelepiped.
  • the shaped sheet 13 has a unitary thickness varying from about 1 to about 3 millimeters, advantageously about 1.20 millimeters, and comprises an impermeable and glossy outer layer 13a, an inner layer 13b made of simple paper, and an intermediate layer 13c consisting of an undulating sheet able to separate the outer layer 13a and the inner layer 13b, and to define a plurality of air spaces which increase the isothermal capacities of the first container 11.
  • the outer layer 13a can have its outer surface printed with high quality print, to carry a plurality of graphical and alphanumerical symbols that identify the product contained and/or other decorative patterns.
  • the shaped sheet 13 (fig. 3) comprises four central walls 24 connected together and able to be folded by 90° one with respect to the other so as to form a quadrangular structure, four thickening fins 14 able to be folded by 180° in order to double the thickness of the relative central walls 24, and four closing fins 18 able to be folded by 90° two by two one on the other, in order to define two lateral closing walls of the box-like structure 15, both having a double thickness.
  • the box-like structure 15 is closed by means of a tongue 22 made in a piece on one of the central walls 24 of the shaped sheet 13, and inserted in a corresponding through slit 23 made on one of the closing fins 18. This closure allows to prevent any accidental opening of the first container 11, and prevents the leakage of air from inside to outside the box-like structure 15.
  • the second container 12 is substantially diamond-shaped and comprises, in this case, a lower half-shell 16 and a covering upper half-shell 17, able to be selectively coupled together in order to define a containing compartment 19 for the ice cream.
  • Both the lower half-shell 16 and the upper half-shell 17 have a very limited thickness, for example varying from about 0.5 to about 0.9 millimeters according to the quantity of ice cream contained, and are made of plastic material for foodstuffs, such as for example PS (polystyrene), PP (polypropylene), PET (polyethylene terephthalate), PVC (polyvinyl chloride) or others.
  • the two half-shells 16 and 17 are able to be coupled reciprocally in fitted manner by means of coupling systems of a substantially known type, suitable to guarantee the solid closure thereof until a desired manual intervention.
  • the lower half-shell 16 acts as a tub for the ice cream and has a bottom wall 16a provided below with a supporting frame 20 (fig. 2), by means of which it contacts the inner lower surface of the box-like structure 15.
  • the upper half-shell 17 contacts the inner lateral surfaces of the box-like structure 15 with an upper edge 21, so as to prevent the second container 12 from moving laterally inside the first container 11 when the isothermal pack 10 is transported.
  • the supporting frame 20 and the upper edge 21 are the only parts of the second container 12 that contact the first container 11.
  • the possibilities of dissipating the temperature due to contact between the two containers 11 and 12 are reduced to a minimum.
  • the substantially diamond shape of the second container 12 allows to contain the greatest possible quantity of ice cream, thus optimizing functionality.
  • the lower half-shell 16 rests with all its bottom wall 16a on the inner lower surface of the box-like structure 15.
