Definitions

  • the invention relates to a screw cap of the type mentioned in the preamble of claim 1 for closing a bottle or the like.
  • a screw cap is known in which the stop for the defined contact of the holding part on the edge of the bottle neck is arranged in such a radial area that it comes to rest when screwing onto an end face of the bottle neck. Since the sealing part also bears against the edge of the bottle neck, generally further inside, the mutual position of the holding part and the sealing part is precisely defined. However, this also defines the magnitude of the force with which the sealing part is pressed against the bottle neck or the seal located in between. The consequence of this is that the pressure at which the seal or the sealing part lifts off the end edge of the bottle rim is also precisely determined, ie the pressure relief valve formed as a whole opens.
  • a screw cap of the type in question in which a brake element with a run-up flank is provided on the inner wall of the holding part, which is located in the area of the screw line of an external thread and a bottle neck and is used for the run-on of the external thread convert the screwing forces onto the brake element into a radial force component and thus overcome the brake element and thus radially outwards to displace.
  • This is intended to bring the screw cap to a standstill with a delay in order to prevent the cap from being screwed onto the container mouth with excessive torque.
  • a precise gap between the bottom of the screw cap and the edge of the bottle neck cannot be achieved.
  • the invention has for its object to provide a screw cap of the type in question for closing a bottle or the like, in which the design of the stop facilitates and a precise distance between the bottom of the screw cap and the front edge of a bottle neck can be reached.
  • the basic idea of this teaching is to arrange the stop surface on the screw cap so that it does not come into contact with the front edge of the bottle neck, but outside it on a stop provided on the outer wall of the bottle neck.
  • This is achieved in that the stop surface is arranged on an inner wall of the cylindrical holding part in a plane perpendicular to the screw axis. In the simplest case, it comes to rest directly on the end of the screw thread facing the front edge of the bottle neck, which forms a counter-stop, on the outer wall of the bottle neck and thus determines the screw-on depth of the screw cap and thus at the same time the distance of the sealing part from the front edge of the bottle neck.
  • the counterstop is formed by an annular, circumferential stop surface arranged on the outer surface of the bottle neck.
  • the screw cap shown in section in Fig. 1 consists of a cylindrical holding part 1, on the inner wall of which there is an internal thread 2.
  • the bottom of the screw cap forms a sealing part 3, on the inner wall 4 of which a flexible seal 5, for example made of foam of certain compressibility, bears, preferably held there by gluing, pressing or the like.
  • annular stop surface 6 is formed, which is directed in the screw-on direction and acts as a stop when screwing on, as is shown in more detail in FIG. 2 can be seen.
  • Fig. 2 the screw cap is screwed onto an external thread 7 of a bottle neck 8 which is only partially shown. It can be seen that the abutment surface 6 rests on the last thread part 10 lying closest to an end edge 9 of the bottle neck 8. As a result, the screw-on depth of the screw cap is limited and precisely defined. At the same time, this defines the gap between the end face 9 of the bottle neck 8 and the bottom 4 of the sealing part 3. In this gap there is the seal 5, which consists of compressible material. By appropriate dimensioning of the thickness of the seal 5 and / or the dimensioning of the gap between the end face 9 and the bottom 4, the force is precisely determined, even after repeated screwing, with which the seal 5 is pressed together and rests on the end face 9. At the same time, this contact force is decisive for the pressure, which, when exceeded, releases an excess pressure from inside the bottle.
