Definitions

  • the invention relates first to a closure device for a container having a container opening, wherein the closure device comprises a lid member for closing the container opening, a lid member associated with the chamber and an inner housing, further comprising the chamber and the inner housing mutually corresponding closure means and opening means which interact with one another such that a discharge opening associated with the chamber as opening means can be released relative to the inner housing by a rotating movement of the closure element connected to the cover element, so that a medium stored in the chamber can escape into the container.
  • Closure devices of the aforementioned type are known in the art. These serve to close off a container and at the same time to provide a chamber for the separate storage of liquid or powdery media, for example tea essences or the like, so that it does not react immediately upon filling the container with the contents of the container, i. For example, water, come into contact and / or mixed, but only at the moment in which the closure device is removed from the container. This is usually the moment in which the content of the container is to be consumed.
  • liquid or powdery media for example tea essences or the like

  • the medium stored in the chamber can exit into the container, where it is mixed with the medium in the container.
  • the invention is concerned with the task of specifying a closure device, which allows for effective producibility effective emptying of the chamber in the course of removal of the cover element.

  • the passage region may be a region which is tapered over the entire circumference or only part of the circumference of the closure means. If the tapered region protrudes upwards out of the opening means by corresponding rotation of the cover element, a free space is created through which mass contained in the chamber, in particular a liquid, can flow out of the discharge opening.

  • the closure pin is removed from the closure opening, so that the medium contained in the chamber can flow through the closure opening into the container .
  • the chamber is advantageously introduced concentrically into the inner housing, wherein the closure pin is displaced simultaneously into a position closing the closure opening. Since the plug is firmly connected to the chamber, it retains its relative position and orientation to the chamber even during assembly of the plug so that it automatically comes into contact with the plug through the position and orientation of the chamber.
  • the cover member is relatively movable relative to the chamber in a removal direction of the lid member in a first movement portion of the lid member in the course of removing the cover member of the container relative to the container and in a second Motion section with the container is motion coupled.
