The invention relates to a controllable flow pourer mechanism. This pourer mechanism comprises a valve mounted on an actuating device, of such construction that in closed position, the valve is kept in fluid-tight contact upon the lip of the pourer spout and that, from this position, in a first phase, the valve slides upon the lip of the pourer spout and, in a second phase, the valve carries out a rocking movement. The invention is applied especially to effect mixtures of liquid products.

1. A controllable flow pourer mechanism comprising, a vessel having a closable orifice, a closure element (8), means for actuating the pourer mechanism comprising a lever (4) supporting said closure element, means for pivoting said lever on a wall of the vessel, a moveable joint between said lever and said closure element, said moveable joint providing for a sliding and pivoting movement of said closure element relative to said lever, a biasing means for biasing said closure element against said closable orifice, and stop means (9) for blocking the angular position of said closure element relative to said pivoting lever at the end of the opening of said closure element. 2. A controllable flow pourer mechanism, comprising: a. a pourer spout projecting from a base, said pourer spout defining a pourer mouth with a lip therearound; b. a valve element mounted relative to said pourer spout to maintain a fluid-tight contact seal with said lip; and c. means for mounting said valve element relative to said pourer spout such that, during opening, the valve element is withdrawn from said pourer mouth in a first phase movement during which said valve element slides on said lip of the pourer spout to progressively clear said pourer mouth to an opening, the maximum area of which is a predetermined fraction of the area of the pourer mouth, and a second phase movement, after said maximum area is reached, during which said valve element is pivotally moved to completely open and free said pourer mouth, said mounting means including a bent lever pivoted at said spout base, the movement of said bent lever being controlled by a rod, said bent lever comprising in its free end a hole through which freely passes and swivels a rod bearing, at its lower end, said valve element, and at its upper part an end of a lift stop to limit the relative stroke of the rod through its hole, and a spring supported on said lever and biasing it downwardly. 3. Pourer mechanism according to claim 2, wherein said spring is cone-shaped helical spring. 4. Pourer mechanism according to claim 1 or 2 or 3, wherein said closure or valve element includes a blade coated with an antisticking material. 5. Pourer mechanism according to claim 4, said antisticking material comprising polytetrafluoroethylene. 6. A controllable flow pourer mechanism, comprising: a. a pourer spout defining a pourer mouth with a lip therearound; b. a valve element mounted relative to said pourer spout to maintain a fluid-tight contact seal with said lip; and c. means for mounting said valve element relative to said pourer spout such that, during opening, the valve element is withdrawn from said pourer mouth in a first phase movement during which said valve element slides on said lip of the pourer spout to progressively clear said pourer mouth to an opening, the maximum area of which is a predetermined fraction of the area of the pourer mouth, and a second phase movement, after said maximum area is reached, during which said valve element is pivotally moved to completely open and free said pourer mouth, said mounting means including a straight lever pivoted at said spout base and having, near its free end, two lateral protuberances and a jointed piece in which a jointed rod pivots, said free end pivotally mounting a cap having two lateral edges which, in a closed position, extend above the opening of the pourer mouth, a fluid-tight blade pivoted in the front of said cap comprised of polytetrafluoroethylene material, said cap being biased at closing by two lateral springs respectively fixed at each of their ends, to said spout base and said lateral edges. 7. Pourer element according to claim 6, wherein said straight lever additionally comprises a hammer means for opening an air inlet hole provided in the spout. 8. A controllable flow pourer mechanism, comprising: a. a pourer spout defining a pourer mouth with a lip therearound; b. a valve element mounted relative to said pourer spout to maintain a fluid-tight contact seal with said lip; and c. means for mounting said valve element relative to said pourer spout such that, during opening, the valve element is withdrawn from said pourer mouth in a first phase movement during which said valve element slides on said lip of the pourer spout to progressively clear said pourer mouth to an opening, the maximum area of which is a predetermined fraction of the area of the pourer mouth, and a second phase movement, after said maximum area is reached, during which said valve element is pivotally moved to completely open and free said pourer mouth, said mounting means including a straight lever pivoted at said spout base and having, near its free end, two lateral protuberances and a lever arm, which can be depressed to cause the opening of the pourer element, in which a jointed rod pivots, said free end pivotally mounting a cap having two lateral edges which, in a closed position, extend above the opening of the pourer mouth, a fluid-tight blade pivoted in the front of said cap comprised of polytetrafluoroethylene material, said cap being biased at closing by two lateral springs respectively fixed at each of their ends, to said spout base and said lateral edges.
