Definitions

  • the invention relates to a screw cap in the preamble of claim 1 type for closing a bottle or the like.
  • DE 41 08 453 A1 is a screw cap of the relevant Kind known in which the inward facing Locking projections are hook-shaped, so that when screwing the screw cap onto the external thread for the first time the locking projections behind a bottle neck one arranged on the bottle neck for security purposes, Snap the circumferential outer bead.
  • the screw cap When unscrewing the Screw cap hold the hook-shaped locking projections Retaining ring behind the outer bead on the bottle neck, so that the thin webs between the circlip and tear off the cylindrical part of the screw cap and so the locking ring remains on the bottle neck. Thereby tamper-evident is given.
  • a disadvantage of this known screw cap is in that with very careful and slow screwing the screw cap and underneath the hook-shaped projections is possible, but this over to lift the outer bead on the bottle neck so that the webs between the snap ring and the cylindrical part of the Screw cap must not be destroyed. This makes it possible replace the contents of the bottle in whole or in part or contaminate and screw the screw cap back on, without this being visible. Although needed this manipulation of a certain skill, however ensuring the originality of the contents is limited.
  • DE 35 31 508 A1 is a screw cap similar to that known type in which instead of the circlip a guarantee margin is provided which extends over part of the The circumference of the bottle neck extends and by means of molded Bridges is connected to the edge of the cap. At the guarantee edge there is a locking projection on the inside. This locking projection slides over the bottle rim when screwing on the screw cap provided annular bead, the guarantee margin swings outward like a hinge around the webs. In the end position the locking projection lies behind the bead. When screwing on the locking projection remains behind the bead, so that the guarantee edge is pulled away from the screw cap.
  • a screw cap is in the preamble of claim 1 type known, in which the Circlip has inward projections that should reach behind an outer bead on the edge of the bottle.
  • locking projections can be done with a flat object, e.g. B. with a knife tip, so that it is possible is the screw cap with constant underriding at the same time open with a knife tip without the Break predetermined breaking points and thus the circlip with the Screw cap can be removed.
  • a flat object e.g. B. with a knife tip
  • the invention has for its object a screw cap of the type in question, in which manipulation excluded with greater certainty on the circlip is.
  • the basic idea of this teaching is to prevent that a thin knife or the like between the bottleneck and locking projections pushed and then several times is moved around the circumference of the bottle neck while at the same time the screw cap is carefully unscrewed, so that the locking projections on the bead Bottle edge to be lifted and finally over this can slide away.
  • the thin knife or tool in each case under a locking projection to push would take the time to to reach all locking projections several times, so large that in The result is a very good safeguard against this type of manipulation given is.
  • tongues are arranged in the circumferential direction towards each other and are directed obliquely inwards. This means that the Half of the tongues in one direction and the other Half bent in the other direction. A manipulation tool thus gets caught when the attempt of the Bypassing the bottle neck is made immediately behind one of the tongues so that further movement is not possible is.
  • the tongues prevent the Locking projections.
  • the tongues are expediently in the circumferential direction trained so long that at least they are screwed on Condition the locking projections on the bottle neck facing Reach behind side. So the tongues are always there securely on the bottle neck and therefore do not offer a gap, through which a manipulation tool in the circumferential direction of the Bottleneck could be guided to the locking tabs to be lifted repeatedly in succession.
  • the tongues are advantageously resilient on the bottle neck on. As a result, you tighten the locking ring radially outwards.
  • the retaining ring at least in the circumferential direction a predetermined breaking point. This tears when you open the Screw cap when the locking projections on the bead on the bottle neck be held back.
  • the predetermined breaking point Through the through the tongues Preload caused by the circlip after Tear open the predetermined breaking point so that between the Gaps that are easily visible, so that this guarantees a guarantee.
  • the basic idea of the invention to provide special tongues that are intended to prevent manipulation basically also applicable when the cap is not through a screw thread, but through a snap connection or the like is held.
  • Fig. 1 shows a screw cap 1 made of plastic according to an embodiment of the invention. It shows one Bottom 2 and a cylindrical screw 3 with a Internal thread 4 for screwing onto an external thread 5 a bottle neck 6, which is only partially shown. Between the bottom 2 and a front edge 7 of the bottle neck 6 there is a seal 8.
  • a lower edge 9 of the cylindrical part 3 is over Predetermined breaking points 10 connected to a retaining ring 11, the inside has locking projections 12, which in the illustrated Unscrew an outer bead 13 on the bottle neck 6 reach behind.
  • tongues 14 On the inside of the circlip 11 are also tongues 14 which are resilient on an outer wall 15 of the bottle neck 6 issue.
  • FIG. 2 shows a section II-II through FIG. 1.
  • the tongues 14 in the spaces between the locking projections 12 are located and in pairs adjacent to the locking projections 12 are arranged and facing each other.
  • the locking ring 11 predetermined breaking points 16 in the form of axially in the circumference of the retaining ring 11 arranged notches.
  • FIG. 3 shows an enlarged section from FIG. 1 in the area of the lower left part of the screw cap, and in such a way that the screw cap is not screwed on and so the bottle neck 6 is omitted.
  • Fig. 4 shows a view IV in Fig. 3 in the lower Area. It can be seen that the two in this Representation of visible tongues 14 outside of the Inner wall of the locking ring 11 towards each other in the Extend area of the locking projection 12.
  • Fig. 5 shows a section V-V through Fig. 3.
  • Fig. 5 shows a section V-V through Fig. 3.
  • FIG. 6 corresponds essentially to the representation according to Fig. 5, however, shows the situation when screwed Screw cap. It can be seen that the tongues 14 bent inwards and thus put under tension are, while they engage behind the locking projections 12.
