Definitions

  • the present invention relates to a valve device for the metered discharge of a medium from a container and a container closure part and a container with such a valve device.
  • Valve devices of the type of interest here are used in particular for metered removal from containers for liquid or pasty media such as personal care products (for example creams), cleaning agents (for example dishwashing liquid) or foods (for example honey or beverages), the medium in the container should be sealed against the exterior of the container when not in use.

  • cleaning agents for example dishwashing liquid
  • foods for example honey or beverages
  • the medium in the container should be sealed against the exterior of the container when not in use.
  • the requirements for the sealing effect are increased so that automatic emptying is avoided.
  • Valve devices of this type are arranged in the region of an opening of the container in question, the container also being able to be made up of several parts and in this case the opening being formed on a container closure (container closure part).
  • the containers or their closure parts are usually prefabricated and the valve devices are initially installed as separate structural units within the container closure.
  • Valves are known for compressible plastic containers in which the filling medium is sealed by means of an elastic membrane provided with a slot or cross slot.
  • an elastic membrane provided with a slot or cross slot.
  • the container internal pressure increases and the membrane is deformed in such a way that an opening in the membrane is created in the slotted area of the membrane by a flap-like bending of membrane tabs.
  • the membrane opening closes again by resetting the membrane tabs. Due to the lack of product volume after removal and The elastic relaxation of the container creates a negative pressure in the container.
  • the membrane flaps fold towards the interior of the container and air flows from the exterior of the container into the container until the vacuum is at least partially released and the membrane flaps reset.
  • the container is largely restored to its original shape, so that a "sunken" appearance of the container after removal is avoided.
  • the known valve described above serves both for the outlet of the medium from the container and for the inlet of air into the container.
  • the valve characteristics for these two opening directions in particular the pressure differences necessary to open the valve, cannot therefore be designed independently of one another. Rather, in practice a compromise has to be chosen between the desired outlet and inlet characteristics.
  • the provision of a single valve for both the outlet of the medium as well as the inlet of air also has the disadvantage, in the case of viscous media, that when pressure is repeatedly applied to the container for the purpose of removing a large amount of the medium, the medium each time air is admitted from the inside of the valve is partially displaced, so that when pressure is again exerted on the container, part of the previously let-in air initially flows out in an undesirable manner.
  • the valve device comprises a barrier part and a sealing ring, wherein a radially outer edge region of the sealing ring is designed to be in connection with the edge of the container opening in a sealing arrangement for the medium in the container and a radially inner edge region when the valve device is arranged of the sealing ring for bearing against the barrier part is elastically preloaded such that the sealing ring provides a seal between the edge of the container opening and the barrier part as long as a pressure difference between the inside of the container and the outside of the container is less than a predetermined threshold pressure difference.
  • the sealing function of the valve device is based on the fact that a space between the radially outer edge region of the sealing ring and the barrier part is bridged by the sealing ring.
  • the radially outer edge region of the sealing ring is designed such that when the valve device is arranged in the region of a container opening, the sealing ring seals between the edge of the container opening and the barrier part.
  • the elastic preloading of the radially inner edge region of the sealing ring for abutment against the barrier part ensures, on the one hand, a particularly good sealing effect of the valve device in the closed state, and on the other hand enables the medium to be released due to the pressure on the inside of the valve device.
  • This elastic preload also avoids an explosive opening of the valve and thus throwing away product residues that are located on the outside of the valve. This improves manageability and, in the case of media which are hazardous to health, also improves the safety of the valve device.
  • the outlet cross section of the valve device can also be designed to be relatively large without impairing the sealing effect. It is thus possible in a container provided with a valve device according to the invention to achieve a relatively large medium throughput even with a relatively small expenditure of force, which likewise contributes to improving the manageability.

  • the barrier part can be movable relative to the container opening, for example elastically preloaded to bear against the radially inner edge region of the sealing ring.
  • the barrier part is mounted in a stationary manner relative to the container opening when the valve device is arranged. This fixed storage is structurally simple to implement.

  • the barrier part is connected to a mounting part for its storage. It is advantageous here if the mounting part can be fastened to the container inside the container. This means that there is no need for any means for storing the barrier part on the outside of the valve device, which could impair the aesthetics of the container or the outflow of the medium.
  • An arrangement of one or more struts or ribs can be provided to connect the barrier part to the mounting part. Especially if the connection between the barrier part and If the mounting part is to be rigid for the purpose of a fixed mounting of the barrier part, it is advisable to form the barrier part in one piece with the mounting part. This provides an inexpensive component that both stores and forms the barrier part.

  • the mounting part can have latching means which can be brought into engagement with corresponding counter-latching means of the container.
  • the mounting part is preferably essentially annular.
  • a mounting ring formed in this way can be provided, for example, on its radially inner and / or outer circumference with one or more support surfaces which are suitable for being supported on one or more holding projections in the interior of the container.

However, it is preferred that, when the valve device is arranged, at least part of the sealing ring is clamped between a container wall or a projection of the container and the mounting part. By fastening the mounting part to the container, the sealing ring is also fixed in this case.

  • Such a valve device ensures that an undesired negative pressure is not permanently maintained on the inside of the valve.
