Definitions

  • the invention relates to a self-opening and resealable pouring spout made of plastic for application to a pack for liquids, in particular cardboard / plastic composite pack, with a mounting flange having a base element, a cutting element and a screw cap, wherein the cutting element is rotatably disposed in the interior of the base member and with the screw cap is operatively connected in such a way that the first unscrewing of the screw cap by the cutting element creates a pouring opening in the packing material.
  • Self-opening and resealable pouring elements of the type indicated above are known in practice from a variety of designs. In the process, more and more such pouring elements are emerging, which have a screw cap which, when screwed on for the first time via positive guide elements, causes a cutting element to introduce a pouring opening into the composite material, which was previously completely sealed. Therefore, the known generic pouring elements consist of three parts: base element, cutting element and screw cap.
  • the invention has the object, the above-mentioned and previously described in more detail three-part pouring element in such a way and further, that a particularly simple and therefore cost-effective production is possible. Furthermore, a simple assembly is desired.
  • a self-opening and resealable pouring element according to the preamble of claim 1, characterized in that the base element a plurality of distributed on its inner wall guide webs with changing pitch and the cutting element has on its outer wall a plurality of appropriately distributed arranged guide ribs, so that rotation of the cutting element inside the base element initially followed by a steep and then a flat helix.
  • the cutting element per guide web of the base element preferably has an upper guide rib and a lower guide rib for forcibly guiding the cutting element above and below the respective guide web. It has been found that it is not necessary to produce mutually corresponding threaded sections, since a sufficient positive guidance is already ensured by the use of short guide ribs.
  • the radial guide ribs are provided at least partially simultaneously as a stop for arranged by the screw on a concentric circular path and projecting into the interior of the base member cams as power transmission elements. It is true, too conceivable to provide the arranged in the screw cap cam inside the cutting element, but this is on the one hand due to the poorer leverage disadvantageous and has a negative impact on the casting behavior, since corresponding drivers would be located inside the cutting element and would constrict in this way the clear casting cross section ,
  • a sufficiently stable guide between the base element and cutting element is achieved when the base element has three guide webs and the cutting element corresponding to three groups of guide ribs. Nevertheless, within the scope of the invention, such pouring elements also comprise more than three pairs of guide means.
  • the guide webs have at their lower end a recess for receiving the upper guide ribs and that the upper guide ribs are forcibly guided during the initial screwing of the screw in these recesses.
  • the cams in the screw cap can be shaped accordingly at their ends, so that when re-closing (screwing) of the screw cap, the upper guide ribs are always pressed into the recesses.
  • the lower radial guide ribs are arranged inclined and corresponds to the inclination substantially the average slope of the guide webs of the base member.
  • the screw cap is made separately from the base element and cutting element.
  • a connection recognizable by the consumer and destroying upon first opening is applied as a tamper-evident seal between the base element and the screw cap.
  • the consumer can tell whether the pouring element has already been opened once or not.
  • the pouring element can be seen in the position as it is removed from the injection mold.
  • the pouring element initially has a base element 1 with a peripheral fastening flange 2 and an external thread 3.
  • a cutting element 4 In the interior of the base element 1 is a cutting element 4, which is provided on its underside with a plurality of teeth. The positive guidance between the base element 1 and the cutting element 4 takes place on the one hand via guide webs 6 arranged in the interior of the hollow cylindrical base element 1 and also on the outside of the cutting element 4 arranged guide ribs 7 and 8, will be discussed in more detail.
  • the pouring element is closed by a screw cap 9, which has cams 10 arranged in its interior on a concentric circular path, which serve as force transmission elements for actuation (rotation) of the cutting element 4 when first screwed on.
  • cams 10 arranged in its interior on a concentric circular path, which serve as force transmission elements for actuation (rotation) of the cutting element 4 when first screwed on.
  • the steep flank of each cam 10 presses against each guide rib 8
  • the screw cap 9 On its inner side, the screw cap 9 has an internal thread 11, which corresponds to the external thread 3 of the base element in a greater pitch.
  • the base element 1 and the screw 9 are by means of a Connecting strap 12 connected together.
  • the connecting plate 12 is arranged between the edge of the screw cap 9 and the mounting flange 2 of the pouring element and has a length which allows pivoting of the screw cap 9 and pressing on the base element 1.
  • connecting lug 12 has a predetermined breaking point 13 towards the fastening flange 2, namely that it is connected to the fastening flange 2 only with two narrow connecting bridges which are not designated in more detail.
  • the connection between base element 1 and cutting element 4 takes place via connecting bridges 14, whose arrangement will be described in more detail below.
  • Fig. 3 shows a fully assembled pouring element, it can be clearly seen that the connecting tab 12 signals the consumer immediately whether the screw cap has already been opened once or not. It therefore serves as a seal of authenticity.
  • Fig. 4 the pouring element according to the invention is shown in a position which shows the individual components after screwing the screw 9.
  • the cutting element 4 is thereby penetrated along the guide webs 6 in the composite material located below the mounting flange 2 and has carried out about a quarter turn.
  • the connecting plate 12 is broken and that the protruding end 12 'has detached from the fastening flange 2.
  • the cutting element 4 does not have excessive teeth at its lower end, but disposes of the arrangement of teeth in a certain area to ensure that the cut piece of composite material does not come off the rest of the composite material to guarantee that it will in no case can leave the composite pack and get into the drink of the consumer. Due to the fact that the cutting element 4 now projects like a tube into the interior of the pack, the partially punched-out composite piece is bent far more downwards, so that the pouring opening always retains its full cross-section.
  • Fig. 5 is now the assembly of base element 1 and cutting element 4 in the sprayed state again shown in vertical section to explain the exact preferred location of the connecting bridges 14. These are located between the outer end of the lower guide ribs 18 and the inner wall of the base member 1. Since here the exact formation of the guide webs 6 is covered by the cutting element 4 is in Fig. 6 a cut base element 1 once again shown without cutting element 4.
  • the guide bar 6 - viewed from top to bottom - initially designed to be relatively steep and then ends relatively flat. This causes a rotation of the cutting element 4 in the interior of the base element 1 to follow first a steep and then a flat helix.
