<p>PROBLEM TO BE SOLVED: To distribute fine particles, powder or semiviscous materials from a supply container, by arranging a valve device which can be selectively moved toward a cover on the exhaust opening of an outside valve element. SOLUTION: Force applied downwardly to an inside valve element 6 drives the lower end of a stem part 16, and the lower end of the stem part 16 and a lower elastic surface with the slits 30 of a cover 24 set in the bottom part of an outside valve element 4 and extended on an exhaust opening, are combined with each other. The elastic quadrants of the cover 24 set between slits 30 are separated from each other so as to open the bottom surface of the cover 24. Products from a container 8 are passed through a part between the hollow head of the inside valve element 6 and the stem part 16, passed through an exhaust opening newly opened, and fun downwardly to the inside of a lower receptacle 10. Also, when a flange 20 is detached from an edge on the receptacle 10 and force applied downwardly to the inside valve element 6 is removed, the elastic return force of the lower surface with the slits 30 of the cover 24 becomes far in the lead, therefore another segment of the cover 24 is returned in a closing position.</p> |
