Definitions

  • the invention relates to a blow-off bottle cap in the form of a cap with or without an internal thread and preferably a circular disk-shaped sealing insert.
  • the object on which the present invention is based is to make it possible, while maintaining the existing closure, to blow off gas under pressure, in particular carbon dioxide gas, for safety reasons, this blow-off process at an internal pressure of the bottles of more than 1 bar, for example between 1 and 4 bar begins, so that the maximum pressure inside the bottle is, for example, a maximum of 4 bar.
  • This object is to be achieved by creating a "one-way valve-like arrangement" in the bottle cap.
  • the aforementioned object is therefore achieved with a bottle stopper of the type mentioned at the outset, that at least one recess is arranged in the edge region of the sealing insert.
  • its internal thread is rolled onto the external thread of a bottle neck.
  • the recess consists of an incision.
  • Another preferred embodiment is characterized in that three recesses, each offset by 120 °, are arranged in the edge region of the sealing insert.
  • closure consists of an aluminum alloy.
  • closure consists of plastic.
  • a further preferred embodiment is characterized in that the sealing insert consists of an inserted and optionally glued-in disc.
  • sealing insert consists of an injected, thrown in or impressed sealant.
  • a further preferred embodiment is characterized in that it is connected to a forgery-proof ring known per se (so-called pilverproof closure) via tear-off webs.
  • Another preferred embodiment is characterized in that openings are arranged in the circumferential jacket.
  • Another preferred embodiment is characterized in that the openings are arranged below the upper knurling.
  • a gas under pressure for example carbon dioxide
  • Such an increase in internal pressure can also occur, for example, if a bottle contains a liquid saturated with carbon dioxide at a lower temperature and the bottle is then exposed to the sun's rays (e.g. when camping) and / or the bottle is subjected to mechanical vibrations, which is often the case, for example, when transporting by car the case is.
  • the gas under pressure seeks the way out, preferably through these openings.
  • the holes also help to open a pressurized bottle.
  • FIGS. 1-4 show exemplary embodiments.
  • the entirety of the bottle stopper is designated by the reference symbol 3, the internal thread by 4, the upper knurling of the circumferential jacket by 5 and the lower knurling by 6.
  • the entirety of the bottle stopper is again designated with the reference number 3, the lower knurling with 6 and the upper knurling with 5;
  • the totality of the bottle stopper is denoted by 3, the lower knurl by 6, the upper knurl by 5 and, in the broken-open area, the sealing insert 1, which has the openings 2 ⁇ and is arranged below the surface 8 of the bottle stopper.
  • the bottle stopper according to the invention has no internal thread as long as it has not yet been rolled onto the external thread of a bottle neck.
