Definitions

  • the present invention concerns a device for opening a container for pourable products.
  • such a device can be applied to a container of the type comprising a laminate provided with at least one paper layer and one aluminium layer, and which is used for containing high density pourable food products, preferably, such as puddings, homogenized fruit, yogurt or the like, specifically to be consumed directly from the container by the use of a spoon or similar products.
  • a container of the type comprising a laminate provided with at least one paper layer and one aluminium layer, and which is used for containing high density pourable food products, preferably, such as puddings, homogenized fruit, yogurt or the like, specifically to be consumed directly from the container by the use of a spoon or similar products.
  • 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.
  • the paper, or cardboard, layer has two discrete pre-weakening lines extending from said perforated portion of the paper, or cardboard, layer
  • the device for opening the container comprises a tab provided with a grip portion, which can be grasped from outside, and a constraining portion comprising a first region which is directly or indirectly constrained to a portion of the aluminium layer at the perforated portion.
  • the grip portion is dragged by the user so to lift said aluminium layer at said at least one first region and, between said at least two pre-weakening lines, said paper, or cardboard, layer, under the action of the above mentioned dragging external force.
  • the above mentioned solution has some drawbacks, mainly relating to the opening device and the perforated portion of the container.
  • the container, at the perforated portion thereof has been observed not to be always opened easily and, occasionally, the product contained inside the container, due to the external force exerted by the user on the grip portion and the side walls, or faces, of the container, can abruptly flow out during the opening, that is just during the dragging of the above mentioned tab and the following dragging of the paper, or cardboard, layer, comprised between the two pre-weakening lines and combined with the tab.
  • the perforated portion lacks of protection against possible perforations and/or outer strokes.
  • opening devices provided with a frame which is arranged around the perforated portion and which, in case of need, is used not only to house a protective lid, but also to house a dragging tab and a cutter, integral - according to the employed opening device - either with the frame of the opening device or the perforated portion of the container.
  • the document EP0558946B1 in name of TETRA LAVAL describes an opening arrangement in which the frame of the opening device, which is welded to the container and surrounds the perforated portion, houses both an opening tab and a cutter.
  • the cutter is integral with the frame of the opening device, whereas the tab is constrained to the container at the perforated portion.
  • Such an opening is also known as a pull-tab opening.
  • said opening device comprises both a cutter and a tab integrally constrained to the frame of the opening device.
  • a frame surrounds the perforated portion of the paper layer, but differently from this the opening tab is constrained to the frame of the opening device.
  • a container for pourable products of the type comprising a laminate provided with at least one paper, or cardboard, layer, 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, wherein 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, said opening device comprising a frame which can be anchored to said container around at least part of said at least one perforated portion and having at least one fixed portion and at least one removable portion, wherein said at least one removable portion is provided with at least one grip portion, which can be grasped from outside, and 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 of said at least one constraining portion is adapted to separate, under the action of an external force, said removable portion from said at least one frame, and to lift, at said at least one first region, said at least one aluminium layer and, between said at least two pre-weakening lines, said at least one paper, or cardboard, layer.
  • Such a solution allows to ease the opening of the above mentioned containers of the known art, that is to say provided with pre-weakening lines on the paper layer, since it increases the overall stiffness of the container - opening device couple.
  • said device comprises a frame which substantially surrounds the perforated portion of the container, the user can firstly exert a high tear force on the grip portion of the removable element without taking care of possible flowing out of the product contained in the container and, in the meanwhile, since the frame comprises a removable portion, the lift of the paper layer comprised between two pre-weakening lines which, however, when the container is closed, lies outside of the frame of the opening device, is allowed.
  • said at least one tab - shaped removable portion is constrained to said at least one frame by a plurality of breakable bridges.
  • said breakable bridges are located at the two sides of said removable portion.
  • said at least one first region of said removable portion, or said tab substantially delimits an edge of said perforated portion comprised between said at least two pre-weakening lines.
  • said opening device comprises, as well, at least one cutter rotatably constrained to said at least one frame, at said fixed portion, for at least partially severing 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 is arranged at least at one second edge of said perforated portion opposite to said first edge comprised between said at least two pre-weakening lines and, preferably, said at least one second edge is arranged in proximity of at least one corner of said container.
  • said at least one constraining portion comprises, as well, at least one second region directly or indirectly constrained, between said at least two pre-weakening lines, on at least part of said at least one paper, or cardboard, layer, wherein said at least one first region and said at least one second region are continuously connected one to another and able to be plastically rotated one to another.
  • said at least one first region and/or said at least one second region extend widthwise substantially between said at least two pre-weakening lines.
  • said at least one frame and/or said at least one cutter are realized in a single piece and they are made of plastic material.
  • said frame is folded at about 90° and is constrained on two adjoining faces of said container. This significantly increases the force the user can exert during the opening steps of the container. Further, such a solution allows the perforated portion to be shifted in proximity of a corner of the container, even more increasing the available gap for opening the container itself.
  • Figures 1a to 1d illustrate a known art container 6 described in the application ITMI2011A002054 in the name of IPI Srl, still in obligation of secrecy, on which an opening device 90 is applied, that is a tab, different from the opening device subject matter of the present invention.
