DEVICE PREVENTING REPEATED FILLING OF CONTAINER Russian patent published in 1999 - IPC

FIELD: materials handling facilities; sealing devices for liquid filled containers. SUBSTANCE: device has cylindrical housing with pass hole in lower end. Liquid flow divider is arranged in housing. Liquid flow divider is made in form of ring with radial ribs uniformly spaced over inner surface of ring. Pass hole is closed by shutoff member. When liquid-filled container is tilted, shutoff member recedes from pass hole providing flowing out of liquid. When container returns to initial position, shutoff member overlaps hole precluding repeated pouring of liquid into container. To provided reliable fixing of shutoff member when pass hole is open and when it is overlapped, lower edges of radial ribs of divider are made with inclination forming cone-like tip pointed towards hole. Shutoff member has conical cavity to suit tip. EFFECT: enhanced operation reliability. 3 cl, 3 dwg
