Patent Name Dumping and Closing Device for Liquid Packaging Patent Applicant SIG Technology Co., Ltd. Principal Applicant Address Inventor of Rhine Falls, Switzerland Application for Marcus Vasum (Patent) No. 03810730.9 Date of Application 2003.05.15 Certification Date Approval Notice No. 1652980 Auditing announcement date 2005.08.10 Manual CD-ROM D0532 Main classification number B65D47/06 Classification number B65D47/06 Partitioning Original application number Priority item 2002.5.16 CH 818/2002 Digest A device for dumping and closing of liquid packaging (2) (1) ) It includes a tilt-down seat (9) with a radially projecting bottom edge (12) and a threaded cap (11). The diameter of the threaded cover (11) is greater than the diameter of the tilting seat (9) and an elastically deformable ring element (10) is disposed between the tilting seat (9) and the threaded cover (11). The ring surface (13) of the ring element is inclined to the plane of the ring, terminating the inner ring edge (14) on the protrusion (15) which can be clamped on the pouring seat (9). The outer ring edge (16) terminates in an upwardly directed projection (25) which is provided with an external thread (26) for screwing on the cap (11). The ring element (10) can be elastically deformed to spring into two stable states, that is, first enters a state in which a ring surface (13) slopes down from the inner edge (14) to the outer ring edge (16). In this state, the pouring closure device (1) is compressed to a height of less than 5 mm. The other condition is that the ring surface (13) rises upwards and the pouring closure device (1) is approximately three times as high, ensuring that the liquid can reliably pour out beyond the 5 mm high rim (6) of the liquid package (2). Located about 11mm from the dump seat (9). Sovereignty item 1. Pour closure device (1) for a liquid package (2) comprising a tilt-down seat (9) with a radially projecting bottom edge (12) and a threaded cover (11), The feature is that the pour closure device (1) can be elastically deformed into two stable states so that it can be moved in the axial direction to a stable compression position and a stable extension position.
