Definitions

  • the invention relates to a closure cap for a container, which is provided with a guarantee band which can be brought into engagement with the container neck and is produced in one piece with the guarantee band from thermoplastic material by injection molding, the guarantee band having a plurality of predetermined breaking bars and a reinforced zone with the lower edge the sealing cap is connected and the wall thickness of the guarantee tape has a reinforcement in the area between two predetermined breaking bars.
  • Sealing caps made of thermoplastic material with a guarantee band which can be brought into engagement with the container neck have been known for a long time and are preferably used in the beverage industry.
  • the guarantee band can either be shrunk onto the container neck, or it can be mechanically engaged with the container neck when the screw cap is screwed on, for example by snapping it behind a bead.
  • Such a closure cap has already become known through the applicant's Swiss Patent 582 099, in which a material web is provided as the reinforced zone, which, after the predetermined breaking webs have torn, the guarantee band is still secured with the Ver end cap connects. This is to prevent the guarantee tape from remaining on the bottle neck. Since the containers are reusable bottles, the guarantee band remaining on the container neck would obviously hinder the cleaning process of the bottles.
  • the applicant's European patent application 34 997 has disclosed a further improved closure cap in which the guarantee band has a reinforcement in the area between two predetermined breaking bars. This reinforcement on the one hand facilitates the injection molding of the closure cap and on the other hand brings about a particularly advantageous shrinking of the guarantee band due to the action of heat.
  • a problem with the known sealing caps is that the material web, which as a reinforced zone still connects the guarantee tape with the sealing cap after tearing, must be made so strong that it can no longer be broken off.
  • the consumer obviously desires to remove the guarantee tape attached to the cap, since it hinders the handling of the cap when the container is reclosed.
  • the material web is made too weak, there is again the risk that the web breaks like the other predetermined breaking webs when the closure cap is screwed on, and that the guarantee band thus remains on the bottle neck.
  • the relatively solid material web also ensures that the guarantee band does not shrink at this point, so that the tamper-evident seal can no longer be fully guaranteed.
  • Another object of the invention is to form shrinkable guarantee bands in such a way that the shrinking process is reinforced by the zone is not obstructed. According to the invention, this object is achieved in that the reinforced zone consists of two approximately vertical holding webs and that the guarantee band between the holding webs is interrupted.
  • the guarantee band no longer forms a continuous ring, but rather a kind of loop, which is still connected to the closure cap in the initial phase of the screwing-on process.
  • This also has the significant advantage that when the closure cap is removed from a mold, in particular an injection molding tool, the guarantee band can be radially compressed, thus ensuring easier demoldability.
  • the cross section of the two retaining webs together is larger than that of an individual predetermined breaking web. In this way, all predetermined breaking bars tear when screwed on, so that the guarantee tape remains connected to the sealing cap for the time being only via the two retaining bars.
  • one of the two retaining webs also tears, although the guarantee band still remains connected to the closure cap. The remaining web can now be easily broken off by hand from the lower edge of the cap.
  • a particularly advantageous shrinking of the guarantee band is made possible if the two retaining webs are arranged in the area between two reinforcements on the guarantee band. In this way, the holding webs shrink against the container neck when exposed to heat. This is particularly the case if the two retaining webs have approximately the same wall thickness as the guarantee band.
  • a closure cap 1 for screwing on a container 2 is screwed onto a container neck 3.
  • the closure cap 1 has a guarantee band 4, which is connected to the lower edge 6 of the closure cap via predetermined breaking webs 5.
  • the guarantee tape is shrunk onto the container neck 3, for example with the aid of a hot air nozzle 10.
  • Figures 3 to 5 show in detail the design of the closure cap according to the invention.
  • Reinforcements 7 are provided between the individual predetermined breaking webs 5, the effect of which has already been described in detail in European patent application 34 997.
  • the guarantee band 4 thus alternately consists of reinforced and thinned zones over its entire scope.
  • two approximately parallel holding webs 8 are arranged, the cross-section of which together is larger than the cross-section of a single predetermined breaking web 5.
  • the guarantee band 4 is interrupted, so that an approximately vertical slot 9 is created.
  • the guarantee band 4 is approximately wedge-shaped in cross section.
  • the two holding webs 8 have approximately the same wall thickness as the widest point of the wedge-shaped guarantee band 4, so that the holding webs do not additionally thicken the guarantee band.
  • the holding webs are advantageously approximately semicircular in cross section.
  • the two holding webs 8 have a width of 0.9 mm and a wall thickness (radius) of 0.45 mm, which is also the wall thickness of the guarantee tape 4 between two reinforcements 7.
  • the slot 9 between two holding webs has a width of 0.5 mm.
  • the individual predetermined breaking webs 5 are also semicircular in cross section, but have a radius of only 0.2 mm.
  • the reinforcements 7 extend over sections of approximately 300, while their wall thickness is 0.6 mm.
  • the reinforced zones 7 also taper in a wedge shape against the lower edge 6 of the closure cap 1.
  • the height of the guarantee band 4 is approximately 4.5 mm. All stated dimensions refer to a cap for a beverage bottle with an MCA standard mouth.
  • the two holding webs 8 together correspond in cross section approximately to the material web previously used as a reinforced zone. Due to the division into two completely separate webs, the guarantee band can be easily separated from the sealing cap. Nevertheless, it is guaranteed that the predetermined breaking bars 5 always tear first and that the guarantee tape remains on the closure cap when screwed on first.
  • the slot 9 between the two holding webs 8 ensures in any case that the guarantee tape 4 does not remain on the container neck 3. Should the two retaining webs 8 tear together with the predetermined breaking webs 5, the guarantee band 4 practically falls off from the container neck 3 by itself, since it does not form a ring, but only an open loop.
  • the configuration according to the invention thus serves not only the filler of the container due to the better shrinking properties and the ease of cleaning the returned containers, but also the consumer, who can easily tear off the guarantee tape from the cap if it does not automatically unscrew from the cap is separated and falls away.
