Definitions

  • the invention relates to a closure cap, in particular Plastic screw cap with a guarantee band, according to the Preamble of claim 1.
  • Such caps with a guarantee tape which about a plurality of connecting webs connected to the cap is becoming more and more prevalent.
  • the guarantee band is with the Cap formed in one piece, in such a way that it through Shrink or by positive locking or by Formation on corresponding beads, cams or in Undercuts on the neck of the container, especially the neck of the bottle is attached. The first time you open or unscrew the Cap is therefore such a resistance through that with the Container neck connected guarantee tape that the At least partially tear connecting webs, so that first opening of the cap is displayed.
  • At some versions of the guarantee tape are also in addition to the At least one connecting strap on the guarantee band itself Predetermined breaking point provided.
  • Caps of the questionable here Art are used as screw caps with internal thread as well provided as snap caps.
  • the present invention is therefore based on the object a cap, in particular screw cap with a To create a guarantee band, on the one hand, its guarantee function well fulfilled, i.e. fast and reliable the first time Opening the container tears, and that on the other hand also through a simple construction and thus manufacture distinguishes as well as sufficient stability for the the cap has to be put on for the first time.
  • An essential measure of the present invention is therefore in that the at least one predetermined breaking point of the Guarantee band obliquely to that by the guarantee band defined plane or obliquely to the vertical.
  • the at least one predetermined breaking point of the Guarantee band obliquely to that by the guarantee band defined plane or obliquely to the vertical.
  • the predetermined breaking point is preferably continuous oblique incision, especially on the outside of the Guarantee band formed incision formed.
  • This Training is particularly easy and technically functionally safe.
  • the incision is continuous, i.e. trained without interruptions. So that's an easy one Production of the Solibruchstelle possible, within the usual manufacturing cycle.
  • connection of the Guarantee tape on the cap or its peripheral jacket is characterized by a spread over the scope continuous incision, especially outer Incision. This incision is preferably in the area of Connection bridges arranged. This measure also promotes asked task with regard to simple manufacture and nevertheless high functional reliability.
  • the connecting webs on the inside in Transitional area between the cap or its peripheral jacket and Guarantee band formed which in an angular range of up to about 40 ° to 70 °, in particular about 60 ° in Unscrew the cap in front of the predetermined breaking point arranged connecting webs a little thicker and / or longer or are more tear-resistant than the other connecting webs.
  • the guarantee band is traditional with one inside with one on the neck of the container or bottle trained collar cooperating projection (Retaining element). That lead is either trained throughout or alternatively in a variety of Projection sections divided.
  • the latter embodiment contributes to minimizing the cost of materials. It is too keep in mind that this is a typical mass product deals, which is produced by the billion. Accordingly, even a small one works Material reduction economically very significant. The latter alternative contributes to this.
  • Guarantee band defined plane preferably an angle of about 30 ° to 60 °, in particular about 40 ° to 45 °.
  • Screw cap 10 Plastic material with an internal thread 11 intended for this is a container, in particular bottle mouth with a close the corresponding external thread.
  • Screw caps are preferred for closing bottles used with soft drinks, which is usually reusable bottles, in particular PET reusable bottles acts.
  • the screw cap 10 is in one piece with a guarantee band 12 connected.
  • the connection is through a variety of approximately arranged evenly distributed over the circumference
  • Connecting bridges or connecting webs 13 made inside in the transition area between the lower edge of the Screw cap 10 or its cylindrical peripheral jacket 14 and the upper edge of the guarantee band 12 are formed.
  • At the the lower edge of the guarantee band points inwards directed projection 15, whose underside inwards is angled to over a filling process ring-shaped collar on the neck of the container or bottle to be able to be pushed.
  • 3 is the after inside projection 15 continuously circular educated.
  • the Connecting webs 13 axially loaded until they break or tear off with the exception of part of the connecting webs, which in an angular range of up to about 30 ° to 70 °, in particular about 60 ° in the screw-on direction according to arrow A of the cap 10 a predetermined breaking point 16 to be described in more detail below Guarantee tape 12 are arranged.
  • These are connecting bridges namely a little thicker and / or longer and accordingly more tear-resistant than the other connecting webs.
  • the thicker connecting bars ensure that the guarantee tape 12 after unscrewing the cap 10 for the first time get stuck.
  • the already mentioned at least one predetermined breaking point of the Guarantee band 12 extends obliquely according to FIG. 1 the level defined by the guarantee band 12 or at an angle to Vertical 17. Specifically, the predetermined breaking point extends into Unscrew direction A from top to bottom, above the entire amount of the guarantee band 12.
  • the predetermined breaking point 16 is through a continuous oblique incision, namely by one on the outside of the guarantee band 12 attached incision formed. This incision closes with the level defined by the guarantee band 12 Angle ⁇ of approximately 30 ° to 60 °, in particular approximately 40 ° to 45 ° on.
  • the guarantee band 12 of the cap 10 or its peripheral jacket 14 by a incision extending throughout the circumference, in particular outer incision 18 separated.
  • This outer incision is technically simple and in connection with the internally arranged connecting webs 13 in the described manner reliable.
  • the cap 10 located in front of the solar break point 16 Connection bridge a bit thicker and accordingly more tear-resistant trained than the rest, especially those in Unscrewing direction of the cap behind the predetermined breaking point 16 located connecting bridges.
  • three or four are in Unscrew the cap in front of the predetermined breaking point 16 located connecting bridges a little thicker and accordingly more tear-resistant than the other connecting webs.
  • This thicker and accordingly more tear-resistant connecting webs are used to unscrew the guarantee tape after the first unscrewing to hold the cap from the bottle neck to the cap after the Predetermined breaking point 16 and all other connecting webs have broken open or torn off.
  • the extent of the somewhat thicker or more tear-resistant connecting webs 13, the delimited on the inside by a circular arc line 19 according to FIG. 5 are significantly smaller than twice the length of the distance between two adjacent connecting webs 13.
  • Correspondingly 5 is the circumferential extension " ⁇ " of the somewhat thicker or more tear-resistant connecting webs 13 only slightly larger than that Angular distance " ⁇ " between two adjacent connecting bars. For the rest, the circumference is somewhat thinner and less tear-resistant connecting webs 13 less than that Angular distance between two adjacent connecting bars.
  • Connecting webs 13 partially conical in plan view expire, i.e. partly conical in the circumferential side wall pass over the guarantee band 12.
  • the screw cap 10 is still like this on the upper inside trained that a sealing washer can be placed under Production of a so-called two-part closure, especially narrow neck closure.
  • Fig. 6 shows that the shape of the Connecting webs 13 at the bottom of the cylindrical Circumferential jacket 14 of the screw cap 10 begins.
  • the latter is with the bottom of the Circumferential jacket 14 of the screw cap 10 continuously, i.e. about connected the entire cross section, as shown in FIG. 6 is shown.
  • the outer one takes place Horizontal section 18 with the formation of the actual Connecting webs 13, as shown in FIGS. 4 and 5, very well reveal. 5 are shown superimposed in FIG both the thicker and the thinner or narrower Connecting webs 13, each inside by Circular arc lines 19 and 20 are limited.
  • the outer Limitation of the connecting webs 13 is made by the inner Limitation of the circumferential incision 18. This inner boundary of the outer cut 18 is in 4 and 5 with the reference numeral 21.
