Abstract

A CLOSURE OF PLASTIC MATERIAL FOR CONTAINERS FOR RECEIVING AND DELIVERING LIQUIDS OR PASTES.THE CLOSURE HAS A RETRACTABLE TURNSPOUT (9). A PLUG (5) FOR CLOSING THE CONTAINER MOUTH HAS ON ITS BASE AN ECCENTRICALLY DISPOSED BUSH (6) WHICH ROTATABLY CARRIES A TURRET (9B). TOGETHER WITH A TRANSVERSELY PROJECTING TUBE (9A) THE TURRET FORMS THE TURNSPOUT. A LIQUID PASSAGE LEADS THROUGH THE TUBE AND TURRET AND THROUGH THE BUSH. BETWEEN THE TUBE AND BUSH A TAP IS FORMED TO SHUT OFF THE LIQUID PASSAGE. A CAP ENGAGES OVER THE PLUG AND CONTAINER MOUTH AND IS ROTATABLE WITH RESPECT TO THE PLUG. BY VIRTUE OF ROTATION OF THE CAP THE TUBE IS PASSED OUTWARDLY THROUGH A LATERAL OPENING (3) IN THE CAP AND WITHDRAWN AGAIN WHEN ROTATED IN THE OPPOSITE DIRECTION. A SHIELD (8) UPSTANDING FROM THE PLUG BASE (5A) SERVES ON THE ONE HAND TO CLOSE THE LATERAL OPENING (3) IN THE CAP, WHEN IN THE CLOSED POSITION, AND ON THE OTHER HAND TO SEAL THE OUTER END OF THE TURNSPOUT. A WALL (26) ON THE CAP BASE (2A) HAS ENGAGING EDGES (39 AND 40) FOR PIVOTING THE TUBE (9A) OUT AND IN. FOR THE PURPOSE OF FURTHER SEALING, THE TURRET (9B) CAN HAVE IN ITS INTERIOR A CONCENTRIC HOLLOW CYLINDER (42) WITH A LONGITUDINAL SLOT (44) FOR THE PASSAGE OF LIQUID AND SEAL WITH RESPECT TO THE WALL OF THE BUSH (6) WHEN THE TUBE IS PIVOTED IN. A TAMPER INDICATOR CAN BE PRODUCED BY A TONGUE (46, 50) WHICH CAN BE BROKEN AWAY AND WHICH SITS IN THE LATERAL OPENING (3) IN THE CAP OR CLOSELY OUTSIDE THIS OPENING. (FIG. 2)
