Lid closure for weithalsfaesser made of plastic

摘要

the deckelverschluu00df for plastic inflated weithalsfu00e4sser (2) uses a halskrauseartigen massive verschluu00dfring (9) made of plastic, at the bottom a distance below the fau00dfu00f6ffnung radially outwardly of the fau00dfwand above, massive bordur (10) above, sow he also produced a plastic gegenring (11).the bottom of the deckelauu00dfenrand (4) angeformten flange (12) can be accessed. the verschluu00dfringe (9, 11) are distributed on the extent arretierhu00fclsen (13, 14) angeformt, in corresponding holes (15, 16) in the fau00dfbordur (10) and the deckelflansch (12) intervention.the verschluu00dfringe (9, 11) and the angeformten arretierhu00fclsen (13, 14) are conical bores (17, 18).for the closure of the weithalsfau00df (2) attached lid (1) by means of a preu00dfwerkzeuges from above spannbolzen (19) made of plastics or metal in the identical each other oriented conical holes (18, 17) of the two verschluu00dfringe (11, 9) injected.with the fau00dfbordur (10) fitting verschluu00dfring (9) by an appropriate device is supported. through the spannbolzen (19) performed the elasticity is deckeldichtung (8) against the u00f6ffnungsrand of fau00dfhalses (3) angepreu00dft.
