Definitions

  • the invention relates to a can-shaped packaging with a body made of paper and / or cardboard composite with a plastic coating provided at least on the inside, a bottom sealed to the body, a tamper-evident closure sealed on the opposite end face, which is opened for the removal of the contents, and a lid made of plastic to reclose the packaging.
  • Packaging of the aforementioned type serve primarily to hold fluid filling goods, such as powder for instant drinks, viscous to pasty foods, such as jams or the like.
  • fluid filling goods such as powder for instant drinks, viscous to pasty foods, such as jams or the like.
  • these packages are circular cylindrical, oval or rounded rectangular.
  • the floor is usually sealed to the fuselage using the hot-melt process.
  • a cover membrane made of a metal foil is generally provided on the cover side and is likewise sealed onto the front side of the fuselage.
  • This sealing membrane in turn is provided with a tear-open tab and, if necessary, a predetermined breaking line in order to be able to easily separate it.
  • the sealing membrane not only forms the tight seal of the packaging, but also forms a tamper-evident seal.
  • a separate plastic lid in the form of an immersion or slip lid is generally provided, which is designed as an injection molded part.
  • the lid also serves as a stabilizing element for transport, storage and storage in the household, in order to keep the not sufficiently rigid body in the area of the closure membrane or - after its separation - in the area of the opening in shape.
  • the invention has for its object to simplify the packaging of the above structure in terms of construction and to make it more economical and environmentally friendly in terms of cost.
  • the lid consists of a plastic ring part, which is essentially the same shape as the fuselage and sealed on the front side thereof, and an injected disc into the ring part, spanning the fuselage on the front side, of paper and / or cardboard composite , which is covered along its circumference by a narrow strip of material of the ring part, which in turn is separable over part of the circumference.
  • the previously necessary closure membrane is dispensed with, in that the lid itself is sealed onto the fuselage and thus forms the closure which ensures the necessary tightness.
  • the sealed lid represents the tamper-evident closure.
  • the lid is not made entirely of plastic, but only in the circumference of the ring part which is sealed onto the fuselage. This ring part nevertheless gives the packaging sufficient dimensional stability.
  • the majority of the lid is formed by a cardboard, cardboard or paper or cardboard composite disk spanning the cross section of the fuselage. This disc only needs to have a stiffness that prevents indentation.
  • container lids have already been proposed in packaging technology, which consist of a plastic / cardboard composite, these are simple slip or immersion lids, which neither fulfill the function of a tightness and tamper-evident closure, nor do they have an integrated opening mechanism.
  • a preferred embodiment is characterized in that the disc has a prefabricated bending line which coincides approximately with the connecting line of the end points of the separable part of the material strip.
  • the pane can be lifted or opened without problems in order to be able to remove the filling material.
  • the hinged part of the pane can be easily brought back into the closed position.
  • the bending line can be designed and attached so that it exerts a restoring force on the foldable part of the disc, which forces it into the closed position.
  • the partially detachable material strip is expediently provided with a tear-open tab which facilitates its detachment, this tear-open tab advantageously being molded onto the ring part in a position parallel to the disk and being bendable upwards in order to obtain an approximately flat ceiling surface when new.
  • pane is provided with a pull tab on the side opposite the bending line, so that the part of the pane intended for opening can also be opened without any problems.
  • the partially detachable material strip also forms an upwardly projecting stacking edge for the bottom of a similar packaging.
  • the partially detachable strip of material in the original state of the packaging forms a stacking edge for transport, storage and presentation of the packaging. If the packaging reaches the end user, the edge of the stack is no longer required, so that it can be partially detached in order to open the packaging and to be able to remove the contents.
  • the ring part has two concentric approaches that closely overlap the fuselage on the front side and on the outside and inside.
  • the ring part can also perform its stabilizing function with respect to the fuselage.
  • the pane can have at least one diffusion-tight, for example metallic, barrier layer. This can be made much thinner than the previously necessary sealing membrane. While conventional sealing membranes have a wall thickness of 50 ⁇ m, a 9 ⁇ m lamination is sufficient for the pane. As a result of this and by saving a large amount of plastic mass, a weight saving in the range of 1/3 can be achieved with regard to the closure.
  • diffusion-tight for example metallic, barrier layer.
  • the fuselage 1 consists of a paper or cardboard composite 3 which has a metallic barrier layer 4 on the inside and a plastic lamination 5 and a paper lamination 6 on the outside for printing.
  • the fuselage 1 is closed on its end face opposite the floor by a closure 2 in the form of a cover.
  • the cover 2 consists of a ring part 7 made of plastic, which tightly engages over the fuselage 1 on the front and outside and inside with two concentric projections 8, 9 projecting downwards.
  • the ring part 7 is sealed to the fuselage 1, for example using the plastic coating 5 on the inside.
  • the cover 2 also has a cardboard or cardboard composite disc 10 spanning the cross section of the fuselage 1, which is embedded, for example injected, into the ring part 7 along its circumference 11.
  • the ring part 7 has an upwardly projecting material strip 12 for this purpose, which at the same time forms a stacking edge.
  • This strip of material 12 overlaps the disk 10 along its entire scope.
  • a material weakening acting as a predetermined breaking line 14 is provided between the material strip 12 and the area 13 that overlaps the end face of the fuselage 1.
  • This predetermined breaking line 14 runs, as can be seen from FIG. 3, along three sides of the packaging, which in this case is rectangular.
  • the material strip 12 also has, as FIG. 3 shows, separation or interfaces 15.
  • a tear-open tab 16 is molded onto the material strip 12, which in the original state, as can be seen in FIG. 3, rests on the pane 10 and, as shown in FIG. 1, can be bent upwards.
  • the material strip 12 can be separated from the ring part along the predetermined breaking lines 14 between the separation points 15, so that only the part of the material strip which can be seen on the right in FIGS. 2 and 3 remains.
  • the disc 10 is approximately along the connecting line of the Trennils. Interfaces 15 are provided with a molded bending line 17. Furthermore, the disc has a pull tab 18 on the side opposite the bending line 17, which is molded onto the ring part and lies flat on the disc in the original state. After the strip of material 12 has been cut off, the pull tab 18 can be gripped and the pane can be raised on this side of the bending line 17. The disc 10 thus forms with its section 19 a kind of cap.
