Abstract (en)
[origin: WO8900958A1] A plastic closure for containers for holding and dispensing liquids or pastes has a retractable spout (9). A stopper (5) for closing the mouth of the container has on its base an eccentric connecting sleeve (6) fitted with a rotary cap (9b). The cap, together with a small tranverse tube (9a), forms the retractable spout. A fluid channel passes through the small tube and cap and through the connecting sleeve. A tap for closing the fluid channel is located between the small tube and the connecting sleeve. The stopper and the mouth of the container are covered by a lid which can be turned with respect to the stopper. When the lid is turned, the small tube is extruded through a side opening (3) in the lid, and when the lid is turned in the reverse direction, the small tube is retracted through the side opening. A vertical diaphragm (8) on the base of the stoper (5a) serves, on the one hand, to close the side opening (3) in the lid in the closed position and, on the other hand, to close the outer end of the retractable spout. A wall (26) arranged on the base of the lid (2a) has driving edges (39 and 40) for extruding or retracting the small tube (9a). To ensure a tighter seal, the lid (9b) can have a hollow internal cylinder (42) with a longitudinal slit (44) for the passage of fluid and can seal off the passage against the wall of the connecting sleeve (6) when the small tube is retracted. A tear-off tab (46, 50) arranged in the side opening (3) of the lid or which seals this opening on the outside can provide a tamperproof seal.
