Definitions

  • the present invention relates to a container.
  • such a container of the type comprising a laminate provided with at least one paper layer and one aluminium layer, is used for containing high density food products, such as puddings, homogenized fruit or the like, etc, to be consumed, preferably, directly from the container.
  • high density food products such as puddings, homogenized fruit or the like, etc
  • Such high density food products usually, are packaged in glass or plastic containers, generally having the shape of pot, or tub, provided with an upper opening relatively large in size to allow a spoon or tea spoon to be introduced within the container, and with a screwed plastic lid or a tab welded to the edges of the opening of the container itself.
  • a spoon, or tea spoon is used, which because of the size of the opening, can deeply enter to collect the food product lying on the bottom of the container.
  • All along the manufacturers of containers comprising a laminated layer provided with at least one paper layer and an aluminium layer advised against using such a kind of containers for containing highly dense food products since it is known that is very difficult to realize such a container which is provided with an upper perforated portion, i.e. located on the upper base, dimensioned so to receive a spoon to empty the container itself and in the meanwhile ensuring the sterility of the product and a suitable structural strength of the container.
  • EP - A1-1939 094 discloses a method for making a container in a multilayer material 1 for pourable products having at least one breakable portion suitable for being removed before pouring said pourable product out of said container.
  • object of the present invention is to realize a container for food products, in particular of the type comprising at least one laminate, allowing a user to consume the product directly from the container.
  • Further object of the present invention is to realize a container which is simple to produce and is not provided with only a suitable structural stiffness, but also it guarantees significantly to preserve the sterility of the food product contained thereon.
  • the present container for pourable products comprising a laminate of the type provided with at least one layer made of paper or cardboard, having at least one perforated portion, and with at least one aluminium layer directly or indirectly applied to the inside of said at least one paper or cardboard layer, and means for opening said container at least at said at least one perforated portion, characterized in that said at least one paper or cardboard layer has at least two discrete pre-weakening lines extending from said at least one perforated portion of said at least one paper or cardboard layer, and in that said means for opening the container comprises at least one tab provided with at least one grip graspable from outside, and with at least one constraining portion comprising at least one first region which is directly or indirectly constrained to at least part of said at least one aluminium layer at said at least one perforated portion, said at least one grip portion being adapted for lifting said at least one aluminium layer at said at least one first region and said at least one paper or cardboard layer between said at least two pre-weakening lines under the action of an external force.
  • such a solution allows the user to take advantage of a large opening that therefore allows the introduction of a spoon, or similar tools, to collect the food product contained in the container.
  • the tab when pulled, drags with it both part of the aluminium layer on which the first region is constrained, also only indirectly, and part of the paper, or cardboard, layer between said two pre-weakening lines, this allows to use the container as if it was a jar and allows the user to consume the food product directly from the container since it provides a large opening, made in part of the perforated portion, obtained by rising the above said layers, through which a spoon or tea spoon for collecting the food product contained in the container is to be introduced.
  • said at least one first region substantially delimits the edge of said perforated portion comprised between said at least two pre-weakening lines.
  • said at least one constraining portion comprises, as well, at least one second region directly or indirectly constrained to at least part of said at least one paper or cardboard layer between said at least two pre-weakening lines, wherein said at least one first region and said at least one second region are continuously connected to each other.
  • said at least one first region and/or said at least one second region, as well as preferably said at least one perforated portion, extend widthwise substantially between said at least two pre-weakening lines.
  • said opening means comprise, as well, at least one cutter to sever at least partially, outside of said at least one first region, said at least one aluminium layer arranged at said perforated portion of said at least one paper, or cardboard, layer, on the opposite side of the above said edge of said perforated portion comprised between said at least two pre-weakening lines.
  • the user severs the aluminium layer located at the perforated portion by the use of a cutter which, preferably, comprises a spoon - shaped portion. Therefore the cutter is also employed to collect the food product contained in the container.
  • said at least one tab and said at least one cutter are made in a single piece and that said at least one cutter and said at least one grip portion are rotatable with respect to said at least one constraining portion such that said at least one cutter at least partially severs, outwardly from said at least one first region, said at least one aluminium layer arranged at said perforated portion of said at least one paper, or cardboard, layer.
  • said at least one cutter and said at least one tab are made of plastic material, and preferably, by molding.
  • the cutter preferably provided with a plurality of teeth, has a curved shape and it extends for most of the length comprised between said two pre-weakening lines.
  • said at least one cutter and said at least one grip portion rotate with respect to said constraining portion, integral with the container, around a plastically deformable hinge.
  • said at least two pre-weakening lines are straight and, preferably, one parallel to another.
  • each of said at least two pre-weakening lines has one or more "T"-, "L”- or “I”- or “C” -shaped orthogonal branches.
  • each pre-weakening line is provided with at least one first plurality of herringbone branches and at least one second plurality of herringbone branches, tilted one with respect to another in an opposing way such that said at least one second plurality of herringbone branches aids to facilitate the rupture of said at least one first plurality of herringbone branches.
  • the said at least one second plurality of herringbone branches is made so that the branches follow a weakening line intersecting the branches of said at least one first plurality of herringbone branches, to facilitate the rupture of the latter. In this way, as the paper layer lifts, the pre-weakening and branching lines are followed the user being unable to deviate from them. This allows avoiding the container to be severed along not pre-established lines and, thus, generating unwanted delamination of the material.
  • said at least one perforated portion preferably having a rectangular shape, is arranged on the front, or back side face, of said container so that it has even more surface for obtaining the opening through which the food product contained in the container is collected.
  • a method for the realization of a container according to the claims from 1 to 17, comprising the steps of: a) forming at least one perforated portion on said at least one paper or cardboard layer; b) applying, either directly or indirectly, said at least one aluminium layer onto the inside of said at least one paper or cardboard layer; c) applying said at least one tab onto said at least one laminate at said at least one perforated portion; characterized in that said step a) includes the step of d) forming at least two discrete pre-weakening lines extending from said at least one perforated portion of said at least one paper or cardboard layer, and that said step c) includes the step of e) constraining, either directly or indirectly, said at least one first region of said at least one tab onto at least part of said at least one aluminium layer. Further, said step e) of the method includes the step of constraining, either directly or indirectly, said at least one second region of said at least one tab onto at least part of said at least one paper or cardboard layer between
  • the invention comprises a further method for opening of a container according to one of the claims from 1 to 17, comprising the steps of: at least partially severing said at least one aluminium layer from the side opposite said edge of said perforated portion and outwardly from said at least one first region, by means of said at least one cutter; dragging said at least one tab in the direction of said at least first region; lifting both said at least one aluminium layer constrained to said at least one first region and said at least one paper or cardboard layer comprised between said at least two discrete pre-weakening lines.
  • said severing step by said cutter is preceded by the step of rotating said tab around said plastically deformable hinge.
  • numeral 1 is shown a container according to the invention.
  • Figure 1 shows a container 1 for high density pourable products 100 such as, for example, a pudding, comprising a laminate 2 provided with a paper layer 3, having a perforated portion 4, and with aluminium layer 5 indirectly internally applied to said paper layer 3.
  • said laminate 1 comprises an outer layer 20 made of thermoplastic material applied outside of said paper layer 3 and an intermediate layer 21 made of thermoplastic material applied between said paper layer 3 and said aluminium layer 5. Therefore, in practice, such an intermediate layer 21 is directly welded to said outside layer 20 at said perforated portion 4.
  • a container comprising a laminate 2, further provided with a plurality of layers made of thermoplastic material or the like applied on the inner face of the aluminium layer still falls within the scope of protection of the present invention.
  • said container comprises means 6 for opening said container 1 at least at said perforated portion 4.
  • said paper layer 3 has two discrete pre-weakening lines 7, 8 extending from said perforated portion 4 of said paper layer 3.
  • said opening means 6 of the container 1 comprise a tab 9, totally in aluminium, provided with a grip portion 10, graspable by the user, and with a constraining portion 11 comprising a first region 12 indirectly constrained, at said perforated portion 4, on at least part of said aluminium layer 5.
  • the tab 9 is welded, by heat - welding, on the outer layer 20, but at the end of the welding it remains substantially constrained both to the intermediate layer 21 and the aluminium layer 5, thus remaining firmly constrained to the latter.
  • said grip portion 10 is adapted to lift said paper layer 3 under the action of an external force exerted by the user, at said first region 12, said aluminium layer 5 and, between said at least two pre-weakening lines 7 and 8.
  • said grip portion 10 is adapted to lift said paper layer 3 under the action of an external force exerted by the user, at said first region 12, said aluminium layer 5 and, between said at least two pre-weakening lines 7 and 8.
  • the aluminium layer 5 arranged under the paper layer 3 keeps being cut along the direction of the two pre-weakening lines 7 and 8 such that an opening 200, much wider than the perforated portion 4 initially present in the container 1, before the opening step, can be obtained.
  • the opening of the container 1 can be facilitated by severing at least part of said aluminium layer 5 by at least one cutter 75, at the available region 70 of said perforated portion 4 and from side opposite to said paper layer 3 comprised between said two pre-weakening lines 7 and 8.
  • said first region 12 substantially delimits the edge 4a of said perforated portion 4 comprised between said at least two pre-weakening lines 7 and 8. Said first region 12 also extends in width L between said two pre-weakening lines 7 and 8. Said perforated portion 4 also extends in width L between said two pre-weakening lines 7 and 8. In view of what said, therefore, the above mentioned available region 70 is on the opposite side of the edge 4a of said perforated portion 4.
  • said constraining portion 11 comprises, as well, a second region 13 constrained between said two pre-weakening lines 7 and 8, indirectly on part of said paper layer 3. In practice said second region 13 of the tab 9 is welded on the outer layer 20, but at the end of the welding it remains substantially constrained to the paper layer 3 to the intermediate layer 21 made of thermoplastic material and to the underlying aluminium layer 5.
  • Said first region 12 and said second region 13 are continuously connected one to another forming a single body. Also, both said first region 12 and said second region 13 extend widthwise L substantially between said two pre-weakening lines 7 and 8.
  • Both the embodiments herein shown provide the two pre-weakening lines 7 and 8 to be straight and parallel one to another, however an alternative embodiment, wherein said two pre-weakening lines are not parallel and not straight, still falls within the scope of protection of the present invention.
  • both said pre-weakening lines 7 and 8 show a plurality of branches orthogonal with respect to the main direction, "T-shaped”, or “L-shaped” or “I-shaped”, or “C-shaped”.
  • both pre-weakening lines 7, 8 are provided with a first plurality of herringbone branches 7a, 8a and with a second plurality of herringbone branches 7b, 8b, one opposing to another and such that said branches of said second plurality of herringbone branches 7b, 8b aid in facilitating the rupture of the branches of said first plurality of herringbone branches 7a, 8a.
  • the branches of said second plurality of herringbone branches 7b, 8b are made so that to follow a weakening line which at a certain point intersects the branches of said first plurality of herringbone branches 7a, 8a.
  • the pre-weakening 7, 8 and branching 7a, 7b, 8a, 8b lines are followed, the user being unable to deviate from them.
  • This allows avoiding the container to be severed along a not pre-established pattern and, thus, giving rise to unwanted delamination of the material.
  • a further pre-weakening 300 line, or creasing is comprised which connect said two pre-weakening lines 7, 8 and allows to completely remove the paper layer 3 lifted during the opening of the container 1.
  • said further pre-weakening lines 300 can have a shape similar to the shape of the pre-weakening lines 7, 8.
  • said further pre-weakening line 300 has a "V" shape it and shows a further series of herringbone branches 300a.
  • said perforated portion 4 is arranged on the front side face 1 a of said container 1. In this way two advantages can be obtained.
  • said perforated portion 4 has a substantially rectangular shape. In this way the dimensions of the perforated portion 4 larger than the classical circular dimensions are exploited.
  • said opening means 6 comprise, as well, a cutter 75 (see figures 1b and 3b ) to sever, outside of said first region 12, from a side opposite to the edge 4a of said perforated portion 4, both said aluminium 5 layer and said outer layer 20 and said intermediate layer 21, each of these latter layers made of thermoplastic material such as, for example, LDPE, being arranged at said perforated portion 4 of said paper layer 3.
