Device for dispensing flowing substances

A dispensing device for flowing substances, said device being attachable to a container and comprising an outlet tube of flexible material adapted to be dependent from the container and at the bottom terminated by an outlet opening, said dispensing device further comprising a valve arrangement comprising two valve members, a first of said valve members being arranged in the vicinity of the upper end of the outlet tube for opening and closing respectively a communication opening, via which the substance may flow from the container into the outlet tube, a second of said valve members being arranged in the vicinity of the outlet opening for opening and closing respectively thereof, said outlet tube having a sufficient length for allowing gripping of the tube by hand in an area between the valve members and squeezing of the tube without mechanically affecting the valve members, said valve arrangement being adapted to be influenced by the fluid pressure in the tube upon squeezing thereof so as to close the communication opening by means of the first valve member and open the outlet opening by means of the second valve member, whereas upon release of squeezing pressure the first valve member opens the communication opening and the second valve member closes the outlet opening, said device comprising an intermediate piece comprising first means for releasably securing the outlet tube to the intermediate piece and second means for releasably securing the intermediate piece to communicate with a discharge opening of the container, said intermediate piece comprising means for restricting movement upwardly of the valve arrangement on squeezing of the outlet tube.
