Definitions

  • Lockable dispensing device for dispensing a liquid, viscous or pasty medium contained in a container
  • the present invention relates to a device according to the preamble of claim 1, i.e. a closable dispensing device for dispensing a liquid, viscous or pasty medium contained in a container, with a dispensing opening for dispensing the medium located in the container, and a closure device, by the actuation of which a connection between the dispensing opening and the container can be established and interrupted , wherein the closure device is formed by an element movable along the connection between the discharge opening and the container.
  • Such dispensing devices can be used, for example, in drinking bottles used by children or by cyclists.
  • the dispensing device described in this document is a device that can be placed on a drinking bottle and consists of a part that is fixed when the bottle is placed and a nipple that can be pushed into it and pulled out of it.
