Definitions

  • the invention relates to a screw closure, in which a thread arranged at the screw mouth of a container has at least one ramp area, which cooperates with a counter surface on a closure to prevent the closure from rotating.
  • DE-A 32 01 330 describes the provision of ramp areas for defining a central position of a lid on a container. This middle position enables a liquid to be poured out of the container. The ramp areas of the internal and external threads work together and get caught in the intermediate position, whereby this is clearly defined. The lid can only be turned forwards or backwards after overcoming resistance.
  • DE-A 28 45 743 describes the provision of a ramp area in the thread of a bottle.
  • the ramp area is used here to determine a tight closed position of the lid on the bottle, in that the ramp area engages in a cutout of the counter thread.
  • the cover is released from its closed position by an elastic expansion of the closure when it is pressed down, the ramp area emerging from the cutout.
  • DE-A 26 34 525 shows a safety closure for containers in which teeth and counter teeth are arranged on the threads of the closure, which cause the cover to be fixed in the closed position. This way the container is secured against unauthorized opening, for example by children.
  • the known screw closures with reverse rotation protection are all characterized by a relatively complex construction for establishing a central or closed position.
  • the present invention finds particular application in glass bottles, the lids of which carry an atomizer pump.
  • This lid with the atomizing pump must be screwed onto the glass bottle once after filling the bottle.
  • the glass bottle has a screw mouth with an external thread, in which at least one ramp area is arranged. By cutting the radially outer edge of the ramp area into the softer plastic cover compared to the ramp area, it is permanently secured against turning back. After using the bottle, the lid can be twisted off the bottle for later separate recycling of the glass bottle and the cap against greater mechanical resistance.
  • the radially outwardly extending ramp area is preferably formed in the screw mouth of the container, for example a glass bottle.
  • the closure which is designed in particular as a carrier for an atomizer pump, is made of a softer material than the screw mouth, the corner or edge of the radially outer end of the ramp area cuts into the closure.
  • the counter surface of the closure therefore does not have to have any special properties.
  • the sharp edges of the ramp areas of the glass thread cut into the surface of the closure facing the thread, as a result of which the closure is deformed elastically or plastically.
  • the closure is reliably held in its closed position by this positive engagement.
  • the invention makes it possible to create a reliable reverse rotation lock.
  • ramp areas are arranged at equal angular intervals on the screw mouth of the container.
  • FIG. 1 shows the screw mouth 10 of a glass bottle 12.
  • the inside of the screw mouth 10 forms the pouring opening of the bottle 12.
  • the outside of the screw mouth 10 has an external thread 14 with two threads.
  • the thread 14 has ramp areas 16, 18 which extend radially outward from the center Z of the screw mouth 10. These ramp areas 16, 18 have at their radially outer ends a sharp edge 20, 22, which is provided for cutting into the areas A Cut the mating surface of a closure in the closed position.
  • the closure not shown, is preferably designed as a carrier for an atomizer pump which, after filling the bottle, only has to be screwed onto the bottle once and is not removed again for the duration of use.
  • the closure or the closure part with the complementary thread is preferably made of a softer material, for example plastic, as a result of which the sharp edges 20, 22 of the ramp regions 16, 18 cut into the closure part without a special configuration of the closure or the Closure part would be necessary. It can thus be used for a screw mouth according to Figures 1 and 2 conventional closures with normal internal threads without a specially designed counter surface. The invention therefore enables an inexpensive and technically simple fixing of the closure in the closed position.
  • the direction in which the closure is screwed onto the screw mouth 10 is represented by arrows in FIG. 2. In this direction it is possible to unscrew the closure slightly. The turning against the direction of the arrow is hindered by the fact that the sharp edges 20, 22 cut into the comparatively softer surface of the closure. Thus, the closed position of the closure is positively secured.
