(57) Abstract It is sealed up is arranged the container (41) vis-a-vis discharge opening, the distribution quantity is done the distribution quantitative system which is offered the product from there, the annular installation flange (70) in the vicinity of opening extending is present inside radial. The valve (30) forming from one material, the head (82), and the peripheral part around (100) elastic structure of the flexibiility which it possesses is demarcated. The head (82), usually closing, when the container (41) the internal pressure the valve (30) just the specified quantity exceeds external pressure, the orifice for the distribution quantity which you open (84) it possesses. The peripheral part (100), the head (82) it is connected, the installation flange (70) the annular the annular in order to receive outside radial was opened groove (104) is demarcated in general wall (102) it possesses in general. The annular wall (102), although the installation flange (70) the groove (104) you install inside, because it corresponds, when the wall (102) is pushed the installation flange (70), in order elasticity to become deformed, sufficiently it is flexibiility. The annular wall (102), because the installation flange (70) the groove (104) it corresponds to keeping inside the annular wall (102) the contiguity part (112 and 114) with, sufficiently it is elasticity.
