  • plastic closure is to provide a resealable closure, which is fastened with little effort in an opening in the wall of the container to be closed.
  • the resealable closure should be particularly suitable for containers in which a liquid, for example, a carbonated beverage is stored.
  • appropriate containers are to be provided.
  • the resealable closure according to the invention is intended for containers which store a liquid, for example a beverage which may also be carbonated.
  • the closure according to the invention initially comprises a fastening insert with which the closure can be inserted into an opening of the container.
  • the fastening insert is used to attach the resealable closure to the container.
  • a hollow truncated cone-shaped bearing is formed in the fastening insert. It is thus a bearing whose interior has the shape of a truncated cone.
  • the blunting of the conical shape allows the technical realization and may possibly be kept very small, whereby the shape of the interior of the bearing is largely approximated to the shape of a cone.
  • the inner wall of the bearing has at least one passage opening which extends over a portion of the inner circumference of the bearing.
  • the passage opening may extend over a quarter of the entire circumference of the cone-shaped inner wall.
  • the passage opening itself may have, for example, a round or a spherically rectangular cross section in the form of a window.
  • passage openings can also be formed a plurality of passage openings, for example, two identical passage openings, each occupy a quarter of the circumference of the cone-shaped inner wall of the bearing and are arranged diametrically opposite one another.
  • the one or more passage openings open into a surface of the fastening insert facing the interior of the container. Consequently, the one or more passage openings in the installed state of the closure according to the invention form constituents of channels, which extend between the interior of the container and the interior of the bearing. Insofar as the passage openings are free, the liquid can flow out of the container through the passage opening into the interior of the bearing.
  • the resealable closure according to the invention furthermore comprises a rotary closure with a sealing cone mounted at least partially rotatably in the bearing.
  • the sealing cone has the outer shape of a truncated cone whose size is adapted to the hollow truncated cone-shaped bearing, so that the outer lateral surface of the closure cone runs parallel to the inner wall of the bearing.

  • the closure cone has at least one outlet opening extending over a portion of the outer circumference of the closure cone.
  • the one or more outlet openings are arranged in the same way as the one or more passage openings in the camp.
  • the one or more outlet openings open into a surface of the rotary closure to be directed out of the container. Consequently, liquid which flows into one of the outlet openings in the inserted state of the closure according to the invention comes out of the rotary closure and thus out of the closure.
  • the passage opening opens into the outlet opening when the closure cone is in a first position. In this first position, the resealable closure is opened. Liquid, which flows into the passage opening, can flow into the outlet opening, since the passage opening and the outlet opening are arranged to open into one another. The liquid that has flowed into the outlet opening can flow out of the closure, because the Outlet opening opens into an outwardly of the container to be addressed surface of the rotary closure.
  • the rotary closure is rotatable with the sealing cone in a second position in which the passage opening and the outlet opening are removed from each other. Consequently, no liquid can flow from the passage opening into the outlet opening.
  • the resealable closure according to the invention is closed. If the closure is inserted into a container, no liquid can flow out of the container through the closure, since the passage opening and the outlet opening do not form a channel.
  • a particular advantage of the reclosable closure according to the invention is that it can be realized with little effort, since essentially only the fastening insert with the hollow truncated cone-shaped bearing and the rotary closure with the sealing cone are required. Due to the arrangement according to the invention, in particular the cooperating conical shapes, a high degree of sealing can be achieved with the closure according to the invention when closing the container to be closed. The conical shapes are considerably easier to produce in comparison to the closure parts known from the prior art. Another advantage of the reclosable closure according to the invention is that the fastening insert can protrude partially or completely into the container, whereby the space requirement of the container to be closed is not or only slightly increased.
  • the closure cone has the shape of a truncated cone shell. This is then given if the closure cone has the external shape of a truncated cone and at the same time hollow inside, wherein the cavity in turn has the shape of a truncated cone, while the remaining thickness of the material of the closure cone is comparatively small to the outer dimensions.
