Definitions

  • the invention relates to a closure device for a container for liquid fuel, which ensures regardless of the orientation of the container, a pressure equalization between a gas space of the container and the exterior, further prevents that liquid can escape unintentionally, and also allows liquid removal, without the Closing device must be removed.
  • a suction tube For the removal of liquid from a stationary container with an opening at the top of the container, a suction tube is immersed through the opening of the container and sucked liquid. In this case, the opening is not sealed in order to allow a subsequent flow of ambient air for the extracted liquid amount.
  • the liquid removal is also possible only in quiet operating conditions, otherwise there is a risk that liquid leaks.
  • a closure device for a liquid fuel container with a pressure compensation device is described in document US 6 142 345.
  • This object is achieved by devices which ensure a pressure equalization during storage and transport of a fuel container, and at the same time make it possible to remove liquid from the fuel container.
  • the pressure compensation device and the fluid passage of the closure device are designed so that the two, that ventilation / liquid removal is possible even with different orientations of the liquid container.
  • the (at least one) further end of the remplisstechniksssaug effets pain serves as (at least one) suction end and is immersed in the liquid (if present in the container), so that liquid can be sucked out of the container in all possible container layers.
  • a suction end for example, by a valve, by a float can be actuated counter to a spring force can be realized. Due to the effect of buoyancy, the float opens the valve when the suction end is immersed in the liquid, while otherwise the spring action keeps the valve closed, so that the suction end is closed when it opens into the gas space.
  • the liquid suction line device has an at least sectionally flexible fluid line which, due to its flexibility, is oriented under its own weight in such a way that the open suction end automatically assumes a position close to the lowest point (or the highest accelerated area). occupies and thus opens into the liquid.
  • the flexible fluid conduit may be in the form of an elastic coil or worm which is fixed at one end and whose open end always occupies the lowest position.
  • the flexible fluid line in the area of the suction end can also be weighted.
  • the flexible liquid line is connected in the region of the suction with the float or another float such that the suction end opens below the liquid level in the liquid.
  • the closure device also comprises an actuatable locking device, the actuation of which via the fluid passageway establishes a fluid connection between the interior and the exterior of the container.
  • the blocking device can be particularly preferably provided in or on the liquid feedthrough.
  • the locking device can be reversibly or irreversibly actuated, which is meant to be irreversible actuated that the locking device no longer closes after a single press, but remains open.

  • the valve is opened, which allows a liquid extraction.
  • the actuating mechanism of the valve is designed so that the valve can not be opened unintentionally.
  • connection device provided for this purpose, which can be connected to the closure device.
  • this connection device For liquid removal then this connection device must be connected to the closure device, for example via a screw or a bayonet connection, wherein the connection process itself can operate the valve, or alternatively can release the opening of the valve via a separate separate operation.
  • a substantially reversible barrier means can also be formed by a septum that has to be pierced through a hollow needle to establish a fluid connection and closes again after removal of the hollow needle.
  • An irreversible locking device can be particularly useful if the closure device is an integral part of the container and this is filled only once and after the beginning of the emptying process is not sooner removed from the associated sampling system until the container is completely emptied.
  • An example of such an irreversible barrier means may be a ball pressed into a tapered region of the fluid passage to obstruct the conduit cross-section, as e.g. as a closure for ink cartridges for fountain pen is known.
  • the liquid feedthrough can also be designed so that it can be closed fluid-tight with a lid or plug, even if the locking device was once irreversibly opened.
  • a gas volume can be displaced by the pressure compensation device, so that there is no pressure increase in the container.
  • the pressure compensation device can be used to fill the container with liquid.
  • Using the Pressure Compensating Device for Filling Liquid may be required when the fluid passage has means (eg, a valve) that allow fluid flow in only one direction, namely, from inside to outside.

Then you have to fill the irreversible barrier means for the liquid feedthrough are not damaged, so that the container can continue to be transported without restriction after the filling process.
  • the closure device according to the invention thus ensures - regardless of the position of the container - a pressure equalization between the container and the outside atmosphere and at the same time allows a liquid removal, without the risk of the liquid splashed or spilled or otherwise escape. If handled properly, a user can never come into contact with the fluid at any time.
