Definitions

  • the invention relates to a plastic bottle cap of the type mentioned in the preamble of claim 1.
  • Bottle closures of the type mentioned are known in large numbers. These bottle caps have radially protruding grip parts on the cap. Furthermore, the bottle closures are provided with a guarantee band and a tear-open tab, the tear-open tab in particular also projecting radially. Since the tear-open tab is intended to be torn off and is therefore connected to the closure cap part by means of tear-off webs, there is a risk that the tear-open tab is unwantedly torn off, for example when sorting or fitting the bottle caps or when handling the bottles provided with the bottle caps. In addition, the radially protruding parts complicate the mechanical processing of the bottle caps.
  • the object of the invention is to provide a bottle cap of the type mentioned, in which in particular the tear tab of the guarantee tape is arranged so that the disadvantages mentioned are avoided.
  • the pull tab is integrated into the closure cap and forms a sector thereof, it is integrated into the contour of the closure cap and no longer forms a protruding part. This results in significant advantages in the mechanical processing of the bottle caps from the production of the same to the attachment to the bottle and also later in the handling of the bottle provided with the bottle cap.
  • the integration of the tear-off tab in the cap also gives the bottle cap an aesthetic appearance.
  • the tear-open tab is easier to handle, since it can only be torn off from the top of the closure cap by radial pressing and pulling out.
  • the guarantee function is improved, because a damaged guarantee closure, ie a torn tear-off tab, leaves a small gap on the cap, which is more visually striking than if a tear-off tab on the side of the known bottle cap is damaged.
  • the design of the bottle stopper makes it easier to tear open the tear-open tab, the integration of the tear-open tab in the closure cap being improved by an embodiment according to claim 3.
  • the bottle cap can be designed so that the cap can be removed after removing the guarantee tape.
  • an embodiment according to claim 4 is more advantageous, in which case after removal of the guarantee band the closure cap can be opened over the hinge part for opening and can be closed again for closing.
  • An embodiment according to claim 5 is advantageous for fastening the bottle stopper.
  • the cap can be placed directly on the head of a bottle, the locking rib engaging behind a radial bead on the bottle head.
  • an embodiment according to claim 6 is expedient, which improves the hold of the closure cap part on the pouring part.
  • the axial support flange also serves to improve the guarantee function, since it makes it difficult to remove the cap part from the pouring part.
  • a further development according to claim 7 is particularly advantageous for this.
  • the design of the bottle cap according to claim 9 increases the sealing of the cap on the bottle head or on the pouring part.
  • An embodiment according to claim 10 is advantageous, as a result of which radial handle parts are eliminated and the mechanical processing and the appearance of the bottle stopper are further improved.
  • a configuration according to claim 11 is particularly advantageous, whereby on the one hand a large handle opening is possible for the handle part and on the other hand the handle part is easier to grasp after the removal of the guarantee band, this facilitates manipulation of the closure cap.
  • Another important advantage is that the handle part is only accessible when the guarantee tape has been removed, so that the guarantee function of the bottle stopper is improved.
  • FIG. 1 shows a bottle cap from a
  • Figure 2 shows the bottle cap of Figure 1 in plan view
  • Figure 3 shows the area of the pull tab
  • Figure 4 shows the bottle cap of Figure 3 in section IV-IV;
  • Figure 5 shows a bottle stopper with a cap part attached directly to the bottle head, in vertical section
  • Figure 6 shows another bottle cap in
  • Figures 1 to 4 show a bottle cap, which is formed from a pouring part 4 attached to a bottle head 2 and a cap part 6 arranged thereon.
  • the bottle cap consists of plastic.
  • the pouring part 4 contains a sleeve 8 with an internal thread 10 which interacts with an external thread 12 of the bottle head 2.
  • a guarantee band 16 is formed via a predetermined breaking point 14, which has an inner locking rib 18 which cooperates with a shoulder 20 on the bottle head 2.
  • the pouring part further contains an inner pouring flange 22 with a pouring rim 24, the opening 26 of the pouring flange 22 being substantially aligned with the opening 28 of the bottle head.
  • the pouring flange 22 is adjoined radially outwardly by an upwardly facing latching flange 30 which is provided with an outer circumferential latching rib 32.
  • the pouring part 4 further contains a support flange 34 lying radially further outward, which extends in the axial direction and has an inner cone 36.
  • the closure cap part 6 interacts, which has the actual closure cap 38 which engages with an insertion apron 40 in the opening 26 of the pouring flange 22.
  • the closure cap 38 also contains an outer downward-pointing flange 42, to which a guarantee band 46 is connected via a predetermined breaking point 44, which in turn is connected to a fastening ring 50 via a predetermined breaking point 48.
  • the latter contains on its inside a circumferential locking rib 52 which interacts with the locking rib 32 of the locking flange 30 of the pouring part.
  • the fastening ring 50 contains a lower outer cone 54, which tapers downwards and interacts with the inner cone 36 of the support flange 34 of the pouring part 4.
  • the arrangement is such that the engagement distance a of the locking ribs 32, 52 is smaller than the axial engagement distance b of the cones 36, 54, so that when the closure cap part 6 is assembled with the pouring part 4, the cones 36, 54 first come into engagement before engage the locking ribs 32.52. This will on the one hand improves the hold of the closure cap part on the pouring part and on the other hand ensures that it is difficult to detach the closure cap part from the pouring part 4.
  • the guarantee band 46 of the closure cap part 6 does not run completely around the closure cap part 6, but is interrupted by a hinge part 56, about which the closure cap 38 can be pivoted when the guarantee band 46 is removed.
  • the guarantee tape 46 contains a tear tab 58, which is formed by a sector of the closure cap 38 and is separated from it by a gap 60.
  • a tear-off web 62 ensures that the pull tab 58 is held on the closure cap.
  • the closure cap 38 contains an upwardly projecting edge part 54, in which the tear tab 58 is integrated. This makes it easier to grasp the tear tab 58 in order to tear it off.
  • the closure cap is provided on the side opposite the hinge part 56 with a grip part 66 which is formed by a radially inwardly extending recess 68, the upper edge 70 of the recess being essentially horizontal.
  • FIG. 5 shows a further embodiment of a bottle cap, the cap part 72 being arranged directly on a bottle head 74.
  • the closure cap part 72 contains a closure cap 76 with an insertion apron 80 which engages in the opening 78 of the bottle head 74.
  • a guarantee band 84 is connected at the bottom via a predetermined breaking point 82, to which a fastening ring 88 is formed via a further predetermined breaking point 86 is.
  • This contains a circumferential locking rib 90 which engages under a bulge 92 of the bottle head which projects outwards.
  • the guarantee tape 84 in turn contains a tear tab 94 which is formed by a sector of the cap 76 and is separated from the rest of the cap by a gap 96.
  • a tear-off bar 98 secures the Tear-off tab 94 on the closure cap 76.
  • the design is such that when the guarantee tape 84 is removed, the closure cap can be completely removed from the bottle head 74 via the handle part 100 which is designed as a recess.
  • the configuration can also be such that the closure cap remains connected to the fastening ring 88 via a hinge part, analogous to the configuration of the bottle closure of FIGS. 1 to 4, when the guarantee band 84 is removed, so that the closure cap can be opened.
  • FIG. 6 shows a further embodiment of the bottle stopper, the stopper cap 102 having a radially downward recess 106 in an outer flange 104, which forms a handle part 108.
  • the recess 106 ie the handle part 108
  • the grip part 108 is only accessible after the guarantee band 110 has been removed.
  • the closure can otherwise be designed as described in the examples above.
