Definitions

  • the present invention relates to a preform for producing a container from thermoplastic, a container made from the preform, in particular a bottle, and a device for closing a mouth region of the container.
  • bottles various types of closure devices for containers, such as beverage bottles, are known from the prior art. So it has long been customary to close beverage bottles with so-called crown caps, which consist of a round piece of sheet metal and which are wrapped around the neck of the bottle with an all-round apron. Bottle caps of this type are an inexpensive and quickly attachable closure system which, however, has the disadvantage that a tool is required to remove the bottle cap from the bottle and, in addition, it is no longer satisfactorily possible to close it once the bottle cap has been opened.
  • the apron is held in contact with the container area surrounding the container opening, for example the bottle neck, which means that the closure device can at most be removed from the container with an unusually high amount of force.
  • the coupling of the sealing part and the handling part via a thread formation, which interacts with a complementary thread formation, can prevent the sealing part from being forced away from the

  • a bottle stopper in which an inner cap is firmly placed on the neck of a bottle to form a spout.
  • An outer cap can be screwed onto the spout to close or open it.
  • An important aspect of this known arrangement is that the spout remains firmly on the bottle neck when the bottle is in use and can only be removed from it by using considerable forces in order to dispose of the bottle and the cap separately from one another.
  • the inner cap forming the spout is firmly attached to the opening of the container to pour liquid out of this container.
  • a pouring cap is known from JP 11-189253 A1, which has a reinforced securing ring for the cap.
