Definitions

  • the present invention relates to the field of disposable packages with break opening for dispensing a liquid, dense or semi-dense product.
  • These packages generally have a flat, rectangular shape and are of limited size, such as to fit in one hand. Normally, they consist of a semi-rigid film and a flexible film applied to an inner face of the semi-rigid film, so as to form a volume for containing the product.
  • the semi-rigid film typically has one or more notches from which, when the semi-rigid film is bent, a fracture is triggered which locally breaks the semi-rigid film, allowing the product contained in the volume to outflow.
  • the two films composing the package have very different functions (a semi-rigid film acts as a support and must undergo localized fracture following bending, the other flexible film has a containing function and must not undergo breakage as a result of the bending of the semi-rigid film to which it is applied), the materials used are different and this does not allow immediate disposal.
  • a disposable package with break opening for dispensing a liquid, dense or semi-dense product consisting of a semi-rigid film, having an inner face and an opposite outer face, and a flexible film sealingly applied to the inner face of the semi-rigid film so as to create a volume for containing the product, in which the semi-rigid film comprises at least one layer of an admixed material, in which:
  • FIG. 1 shows a disposable package with break opening, according to an embodiment of the present invention.
  • FIG. 2 shows the package in FIG. 1 , from a further observation point.
  • FIGS. 3 to 7 diagrammatically show the structure with layers of semi-rigid film of the package, each in a bent configuration, according to different embodiments.
  • numeral 1 indicates, as a whole, a disposable package with break opening according to an embodiment of the present invention.
  • the package 1 comprises a semi-rigid film 2 , having an inner face 4 and an opposite outer face 6 , and a flexible film 8 applied to the inner face 4 of the semi-rigid film 2 , so as to create a volume 10 for containing a liquid, dense or semi-dense product to dispense.
  • the flexible film 8 is sealingly applied to the semi-rigid film 2 , for example by welding, so that the volume 10 is sealingly closed to contain the product.
  • the semi-rigid film 2 preferably has a weakening line 12 , consisting for example of a notch having a predefined depth, from which a local fracture is triggered by bending P the semi-rigid film 2 , which allows the outflow of the product contained in the volume 10 .
  • the package 1 is substantially monomaterial, such a term meaning that at least 80% by weight of the package is made from the same base polymeric material.
  • Such a feature allows an immediate disposal of the package after use, as it consists of a single base material.
  • the materials and the dimensions of the layers of the package are selected so that the package has a relative density ⁇ 1, so as to be floating. Such a feature allows, during waste disposal processes, to separate these packages by floating in water.
  • the flexible film 8 is a coextruded or laminated film, consisting of one or more layers of PE (Polyethylene), possibly interspersed with barrier layers of EVOH (Ethylene-Vinyl-Alcohol) or SiOx (Silicon oxides) or AlOx (aluminum oxides), in which the inner layer is weldable to the inner face 4 of the semi-rigid film 1 and for example made of a polyethylene layer.
  • PE Polyethylene
  • barrier layers of EVOH (Ethylene-Vinyl-Alcohol) or SiOx (Silicon oxides) or AlOx (aluminum oxides) in which the inner layer is weldable to the inner face 4 of the semi-rigid film 1 and for example made of a polyethylene layer.
  • the flexible film 8 is a coextruded or laminated film, consisting of one or more layers of PP (Polypropylene), possibly interspersed with barrier layers of EVOH or SiOx or AlOx, in which the inner layer is weldable to the inner face 4 of the semi-rigid film 1 and for example made of a polypropylene layer.
  • PP Polypropylene
  • the semi-rigid film 1 is coextruded, substantially made of polypropylene and comprises three layers: a first inner layer 2 i , bearing the inner face 4 and intended to come into contact with the product, an intermediate layer 2 m and a first outer layer 2 e , bearing the outer face 6 and intended to receive any weakening line.
  • the first inner layer 2 i is made of PP or comprises two sub-layers of PP interspersed with a barrier sub-layer of EVOH or PVOH (Poly-Vinyl-Alcohol); the intermediate layer 2 m is made of PP; the first outer layer 2 e is made of PP with the addition of a functional additive adapted to increase the rigidity of the material.
  • Said functional additive is selected from the group comprising COCs (Cyclic-Olefin-Copolimers) or other mineral filler, such as talc and/or calcium carbonate, or other nucleating agents.
  • the composition of the first outer layer 2 e makes the PP more rigid and the poor ability to stretch facilitates the fracture on the outer face 6 of the semi-rigid film 1 .
  • the thickness of the semi-rigid film 1 is about 350 microns.
  • FIG. 3 Table 2
  • the structure and composition are substantially identical to those described for Example 1, except for the inner layer, made of admixed PP.
  • a fracture is obtained on the outer face or on the inner face, according to the bending direction, which causes one or the other face to take a convex shape.
  • the semi-rigid film 2 is a laminate and comprises, from the inner face 4 towards the outer face 6 , a first inner layer 2 i bearing the inner face 4 , a second inner layer 2 ii , an intermediate layer 2 m , a second outer layer 2 ee and a first outer layer 2 e.
  • the first inner layer 2 i is of PP; the second inner layer 2 ii is in admixed PP; the intermediate layer 2 m is of PP or is a barrier layer comprising a first sub-layer of PP, an intermediate layer of EVOH or PVOH or other barrier material compatible with PP, and a second sub-layer of PP; the second outer layer is of PP or comprises a first sub-layer of PP, a barrier layer of EVOH or PVOH or other barrier compatible with PP or an adhesive, and a second sub-layer of PP; the first outer layer 2 e is of PP or comprises a first sub-layer of PP, a barrier layer of EVOH or PVOH or other barrier compatible with PP, and a second sub-layer of PP.
  • the total thickness of the semi-rigid film is 410 microns.
  • the fracturable layer which generates the fracture by bending, is the second inner layer 2 ii , in admixed PP.
  • the sum of the thicknesses of the non-admixed layers external to the admixed layer should be equal to or less than half the sum of the thicknesses of the admixed layer and internal thereto.
  • tx is the thickness of the layer X.
  • the weakening line obtained on the outer face 6 preferably has a depth such as not to damage the barrier layer (second outer layer 2 ee or first outer layer 2 e ), thus preserving the integrity thereof.
  • the semi-rigid film 2 is coextruded in several layers, typically 7.
  • the semi-rigid film 2 comprises, from the inner face towards the outer face 6 , a first inner layer 2 i bearing the inner face 4 , a second inner layer 2 ii , an inner binding layer 21 i , a barrier layer 2 o , an outer binding layer 21 e , a second outer layer 2 ee and a first outer layer 2 e.
  • the first inner layer 2 i is of PP
  • the second inner layer 2 ii is in admixed PP
  • the inner binder layer 21 i is a binder or adhesive
  • the barrier layer 2 o is of EVOH or PVOH
  • the outer binder layer 21 e is a binder or adhesive
  • the second outer layer 2 ee is in admixed PP
  • the first outer layer 2 e is of PP.
  • the semi-rigid film has a thickness of 350 microns.
  • the fragile layers which undergo breakage by bending, are the second inner layer 2 ii and the second outer layer 2 ee , which undergo breakage alternately, according to the bending direction.
  • the semi-rigid bottom 2 is made by coupling several semi-rigid bottoms, each of the latter formed as described in the previous examples.
  • a semi-rigid bottom 2 comprises, from the inner face 4 towards the outer face 6 , a first inner layer 2 i bearing the inner face 4 , a second inner layer 2 ii , a third inner layer 2 iii , an inner binder layer 21 i , a barrier layer 2 o , an outer binder layer 21 e , a third outer layer 2 eee , a second outer layer 2 ee and a first outer layer 2 e bearing the outer face 6 .
  • the second inner layer 2 ii is in admixed polypropylene; the second outer layer 2 ee is in admixed polypropylene.
  • the semi-rigid film according to such an embodiment undergoes fracture by bending in one direction or the other and, if provided with weakening lines for the trigger of the fracture, on the inner face and/or on the outer face, the depth of these weakening lines is such as not to affect the barrier layer.
  • a semi-rigid film 2 comprises, from the inner face 4 towards the outer face 6 , a first inner layer 2 i bearing the inner face 4 , a second inner layer 2 ii , a third inner layer 2 iii , an inner binder layer 21 i , a barrier layer 2 o , an outer binder layer 21 e and a first outer layer 2 e , bearing the outer face 6 .
  • the first inner layer 2 i is made of polypropylene
  • the second inner layer 2 ii of admixed polypropylene the third inner layer 2 iii of polypropylene
  • the inner binding layer 21 i is an adhesive
  • the outer binder layer 21 e is an adhesive and the first outer layer 2 e is in BOPP (Biaxially-Oriented-Polypropylene).
  • the barrier layer is coupled by means of an adhesive to an outer layer of bi-oriented plastic material, for example a BOPP, so as to be protected from scratches and impacts.
  • an outer layer of bi-oriented plastic material for example a BOPP
  • such a weakening line preferably has a depth such as to affect at most the third inner layer, without affecting the barrier layer.
  • such a weakening line preferably has a depth such as to affect only the first outer layer, without affecting the barrier layer.
  • the package is shaped so as to take a particular shape, for example a stylized bottle.
  • a particular shape for example a stylized bottle.
  • the package described above meets the field needs, as the bending of the package causes a fracture which allows the product to outflow, and overcomes the aforementioned drawbacks, since the package is substantially monomaterial and therefore easily disposable.
  • the package described above is suitable for selective disposal, since it can be separated by means of the usual separation processes, and in particular by floating in water.
