Abstract (en)
[origin: EP0412285A1] The closure is made of plastic in two parts. A top part (2) comprises an internal thread and a continuous outer surface (207) and an axial outer cylindrical portion (210) and, above the latter, a valve tube (209) which is held by means of a conical transition part (208). A bottom part (1) comprises an external thread (101) and a continuous outer surface (107) and an axial inner cylindrical portion (110) with, at its upper end (112), a sealing bead (111) facing the outer cylindrical portion (210) and, above said sealing bead, a valve pin (109) which is held by means of connecting webs (108). By rotating the top part (2) relative to the bottom part (1), the top part (2) is offset axially relative to the bottom part (1). A sealing part (113) is moulded axially onto the upper end of the valve pin (109). When the closure is screwed completely closed, the sealing part (113) fills the upper opening (206) of the top part (2). Its upper end (114) is flush with or projects over the top part (2) and the valve pin (109) is enclosed by the valve tube (209). When the closure is screwed completely closed, the valve pin (109) is located outside the valve tube (209). A rib (115) on the bottom part (1) and a baffle (215) on the top part (2) interact to limit the rotation of the top part (2) relative to the bottom part (1) by striking against one another to an angle of rotation of less than one complete revolution. <IMAGE>
