Definitions

  • the invention relates to a pouring element for cardboard/plastic composite packagings, more particularly beverage packagings, which comprises a base provided with an opening with a pouring edge and a peripheral flange, and an opening element that can be linearly displaced in a guide, and to a cardboard/plastic composite packaging for use with such a pouring element.
  • DE 44 43 556 A1 discloses a pouring element as specified above, comprising an element arranged displaceably in the base which, after first-time opening of a packaging provided with such a pouring element, simultaneously serves as opening element and as sealing part.
  • This pouring element is characterised by a small overall height, but is in need of improvement in that a separate opening aid is required for opening the pouring opening for the first time, said opening aid representing a separate disposable part after the opening operation.
  • This prior-art pouring element therefore, is not particularly user-friendly, since the opening consists of two steps (pushing up and tearing open).
  • the object of the invention is therefore to configure and refine the pouring element, specified initially and described in detail above, in such a way that the opening operation of a cardboard/plastic composite packaging provided with such a pouring element is improved without having to forego the advantage of small overall height.
  • production costs are to be minimized, which is achieved by single piece construction of the pouring element.
  • the design of the piercing and ripping element in conjunction with rigidly arranged lateral guiding elements ensures “restricted control” of the piercing and ripping element, wherein the linear movement of the opening element, in conjunction with the geometry of the lateral guiding elements cater for the pivot movement of the piercing and ripping element when the packaging is opened for the first time.
  • the piercing and ripping element is joined to the opening element with a film hinge.
  • This embodiment is particularly advantageous as regards its production from a technical aspect.
  • the base and the opening element are preferably constructed in a single piece and are connected to one another by means of a predetermined breaking point, which self-destructs when the packaging is opened for the first time. Production costs for this single piece construction are particularly low, since only one injection-moulding tool is required.
  • a pouring element constructed in such a way according to the invention is injection-moulded in the outstretched position in accordance with a further embodiment of the invention and the base, on its lower surface, has a recess for receiving the opening element, into which the opening element is pivoted about 180° before application onto the packaging.
  • the opening element, outside the base preferably is of two-layer construction and in the assembled position has a film hinge at its end.
  • a predetermined breaking point, between the part of the opening element projecting from the base as a gripping latch and the base, is destroyed when the pouring element according to the invention is opened for the first time and therefore simultaneously serves as a mark of originality.
  • a further teaching of the invention provides that the base and the opening element can also be constructed in two pieces.
  • the two-piece construction permits simpler design of the injection-moulding tools used, but does not require two injection-moulding tools and thus higher production cost.
  • the base can have a lid for re-closing the pouring opening.
  • the lid is configured in such a way that, when it is re-closed also in its pivoted position, it provides a reliable seal with the base.
  • the lid on its lower surface, preferably has a sealing element matching the pouring opening, which may also consist of a flexible material.
  • FIG. 1 a pouring element according to the invention, partly opened, in perspective view,
  • FIG. 2 the pouring element according to the invention, elongated (before final assembly), in perspective view,
  • FIG. 3 the pouring element according to the invention, closed, in plan view
  • FIG. 4 the closed pouring element in cross section along line IV-IV from FIG. 3 ,
  • FIG. 5 the pouring element according to the invention, partly opened, in plan view
  • FIG. 6 the partly opened pouring element in cross section along line VI-VI from FIG. 5 .
  • FIG. 7 the pouring element from FIG. 1 , however with a lid moulded on the base.
  • FIG. 1 shows, in perspective view, a pouring element according to the invention in partly opened position.
  • a base 1 has a peripheral flange 2 for later joining to a not illustrated composite packaging.
  • the base 1 at its front end, possesses a pouring edge 3 and encloses the later pouring opening O.
  • the opening element 4 which at its end has a pivotable piercing and ripping element 5 , adjoins the end of the base 1 turned away from the pouring edge 3 .
  • the function of the piercing and ripping element 5 is clearly recognizable from the further figures and the associated description.
  • FIG. 2 shows how such a pouring element appears after the injection-moulding process, that is to say, before “final assembly”.
  • final assembly it is only necessary to fold down the opening element 4 about 180° in the direction of the arrow not designated in more detail, so that it is received by the base 1 having a corresponding recess A and only a gripping latch G still protrudes from the base.
  • the pouring element according to the invention is applied to the composite packaging having a corresponding weakened zone in the vicinity of the pouring opening.
  • the “finished” pouring element is illustrated in FIGS. 3 and 4 in closed position and in FIGS. 5 and 6 in half open position.
  • a special embodiment of the piercing and ripping element 5 and the base 1 caters for restricted guidance of the piercing and ripping element 5 when the gripping latch G is manipulated.
  • the piercing and ripping element 5 on its upper side, firstly has lateral cams 6 A and 6 B and pressure pads 7 A and 7 B, as particularly clearly recognizable from FIGS. 3 and 5 .
  • the base in the vicinity of the pouring opening O has laterally arranged pins 8 A and 8 B and guide rails 9 A and 9 B.
  • the cams 6 A and 6 B are pressed down by the pins 8 A and 8 B and cause the piercing and ripping element 5 to pivot.
  • the piercing and ripping element 5 on its lower surface, has a plurality of peripherally arranged teeth 10 . After the teeth have penetrated the foil layer after only short displacement of the opening element 4 , the piercing and ripping element 5 is pivoted downwards about 90° under the effect of cooperation between the pressure pads 7 A and 7 B and the guide rails 9 A and 9 B of the base 1 , wherein the extracted foil remains inside the teeth 10 of the piercing and ripping element 5 .
  • the gripping latch G of the pouring element according to the invention possesses elevations 11 , in order to improve the grip during the extraction operation.
  • the opening element 4 and the piercing and ripping element 5 are connected to one another by means of a film hinge 12 .
  • the contact areas 13 A and 13 B adjacent to the film hinge 12 form an angle of 90°, so that the folded piercing and ripping element 5 reliably lies against the opening element 4 .
  • the two contact areas 13 A and 13 B can also have restricted locking elements.
  • the opening element 4 has a plurality of detent elements 14 , which cooperate with a rest edge 15 correspondingly arranged on the lower surface of the base 1 and which keep the opening element 4 fixed in its opened position, as evident from the enlargement in FIG. 4 .
  • the opening element 4 When the packaging is opened for the first-time, the opening element 4 must be separated from the base 1 , for which purpose a predetermined breaking point 16 is provided between the two component parts, which can simultaneously serve as mark of originality, wherein it is indicated to the consumer at a glance whether the packaging has already been previously opened or not.
  • the opening element 4 is of two-layer construction in its area projecting from the base 1 , wherein the layers are connected to one another with a film hinge 17 .
  • the two-layers may be connected to one another, by bonding or welding for example. So that also when the packaging is re-closed a reliable seal in the rear area of the base element 1 is achieved, the opening element, on its lower surface, has a frame 18 , as especially clearly recognizable from FIGS. 2 and 6 .
  • the weakened zone of a paper/plastic composite packaging is constructed as a slit, devoid of the support material in the vicinity of this slit, and the opening in the support material is merely coated with at least one plastic layer. Additionally, the opening can also be sealed by a barrier layer, for example made from aluminium foil.
  • the piercing and ripping element 5 reliably destroys this/these layer/s when the packaging is opened for the first time and exposes the pouring opening O required for pouring by removal over nearly the entire length of the base 1 . In this way, a particularly large exposed surface develops, so that the pouring element according to the invention is also suitable for use with products having chunky ingredients, such as pea soup for example.
