Definitions

  • the invention relates to a screw cap in Preamble of the type mentioned for closing a bottle or the like.
  • DE-A-41 08 453 is a screw cap known type in which the inward Locking projections are hook-shaped, so that when the screw cap is unscrewed for the first time the locking projections on the external thread of a bottle neck behind one for security purposes on the bottle neck snap arranged, surrounding outer bead.
  • unscrewing the screw cap hold the hook-shaped Locking projections the locking ring behind the outer bead on the bottle neck so that the thin Bridges between the circlip and the cylindrical Tear off the predetermined breaking points formed on the screw cap and so the locking ring on the bottle neck remains. This ensures tamper evidence, by screwing the screw cap back on the locking ring is held loosely on the bottle neck is. This makes it easy for everyone to see that the Bottle has already been opened once.
  • a disadvantage of this known screw cap is in that a relatively large torque is required is when the hook-shaped locking projections on the locking ring over the outer bead on the bottle neck be moved away. Because of this increased Torque there is a risk that through the thin Bridges formed predetermined breaking points between the retaining ring and the cylindrical part of the screw cap already sheared off when screwing on, so that subsequently the circlip loosely on the neck of the Bottle is sitting, just as it is when the Bottle opened for the first time and then closed again has been. The originality of the bottle content is therefore not recognizable or guaranteed.
  • a screw cap is in the The preamble of the type mentioned is known. It has projections and depressions on the opposite Edges of cylindrical screw part and circlip that engage axially and cause a positive fit in the circumferential direction, so that when the screw is screwed, the locking ring is taken along take place and should be avoided that inside Circlip connecting cylindrical screw part Break webs.
  • This construction is proportionate complicated because of the protrusions and depressions through a special operation in addition to shaping make the plastic screw cap necessary.
  • a screw cap is known from EP-A-0 281 284, long webs at the predetermined breaking points between each other in the axial direction Areas are available. Due to the length of the webs a relative movement between the circlip and the cap be possible to avoid breaking the webs.
  • On the locking ring are projections with complementary barbs on the bottle neck come and the circlip when unscrewing in the circumferential direction hold on to shear the bars bring to. The total shear forces of Hand applied, which is unscrewing for use much more difficult, possibly so much, that unscrewing by children is not possible.
  • the invention has for its object a To create screw cap of the type in question the risk of tearing the predetermined breaking points between the cylindrical part of the screw cap and the locking ring is reduced when screwing on for the first time.
  • the basic idea of this teaching is that cylindrical part of the screw cap and the locking ring positive in the circumferential direction, in the screwing direction but releasably connected to each other.
  • By positive interlocking of the opposite Edges of the cylindrical part and circlip can handle large torques without mutual rotation of the two parts are transferred so that no danger there is that the circlip in its original condition connecting with the cylindrical part of the screw cap Breaking points are sheared or torn off.
  • the locking projections prevent movement in the circumferential direction Not.
  • the circlip is thus on the Bottle neck freely rotatable.
  • the predetermined breaking points are So not claimed in the circumferential direction, so that not the danger of breaking when screwing on the There is a screw cap after filling. At the first Unscrew the screw cap to remove the contents of the bottle shear the predetermined breaking points in the axial direction since the locking projections on the locking ring Reach behind the outer bead on the bottle neck.
  • Fig. 1 shows a screw cap 1 made of plastic according to an embodiment of the invention. She has a base 2 and a cylindrical screw part 3 with an internal thread 4 for screwing on External thread 5 of a bottle neck 6, which is only partially is shown. Between the floor 2 and one Front edge 7 of the bottle neck 6 is one Seal 8.
  • a lower edge 9 of the cylindrical part 3 is connected to a locking ring 11 via webs 10, the inside has locking projections 12, which in the illustrated Screwing on an outer bead 13 am Reach in behind the bottle neck 6.
  • Fig. 2 shows a view II in Fig. 1. From it it can be seen that a lower edge 14 of the cylindrical Part 3 has rectangular projections 15 which flush in corresponding recesses 16 in the locking ring 11 intervene. Between the projections 15 and the bottom of the recesses 16 is a space 17 formed in which the webs 10 are arranged, the hold the locking ring 11 on the cylindrical part.
  • the projections shown in FIG. 2 provide 15 that the locking ring 11 then is taken without mutual movement if a greater torque occurs which is the case when the locking projections 12 slide onto the outer bead 13 and move over him under tension.
  • the thin webs 10 are during the screwing process secured against shearing or tearing off.
  • the projections 15 lie only on the in the unscrewing direction opposite edge of the recesses 16 on and not in the opposite Direction, the unscrewing direction.
  • the circlip freely rotatable on the bottle neck.
