用于容器开口的密封和开启。
专利摘要
容器封闭件(1)包括一个具有入口开口(2p)的凸缘(2)和一个在流出方向上位于入口开口(2p)之后具有螺纹(2b)的出口管(2a),并包括一个具有出口开口(3p)和螺纹(3i)的旋转封闭件(3),其中两个螺纹(2b,3i)相互啮合并对齐,使得旋转封闭件(3)可相对于凸缘(2)绕旋转轴(D)旋转,并沿旋转轴(D)方向可移动地安装,其中凸缘(2)包括一个朝向旋转轴(D)突出的密封唇(2i),其形成与旋转轴(D)同心的入口开口(2p),其中旋转封闭件(3)具有一个与旋转轴(D)同心布置的插口(3a),其在流出方向上位于入口开口(2p)之后,并且其中插口(3a)和密封唇(2i)设计为相互匹配,使得可沿旋转轴(D)方向移动的插口(3a)可以采取至少两个位置:一个关闭位置(SS),其中插口(3a)接触密封唇(2i),使得入口开口(2p)关闭;以及一个打开位置(OS),其中插口(3a)与密封唇(2i)间隔开,使得入口开口(2p)打开。
Original abstractThe container closure ( 1 ) includes a flange ( 2 ) having an inlet opening ( 2 p ) and an outlet tube ( 2 a ) having a thread ( 2 b ) arranged after the inlet opening ( 2 p ) in the outflow direction and includes a rotary closure ( 3 ) with an outlet opening ( 3 p ) and with a thread ( 3 i ), wherein the two threads ( 2 b , 3 i ) engage into one another and are aligned such that the rotary closure ( 3 ) is rotatable with respect to the flange ( 2 ) about an axis of rotation (D) and is displaceably mounted in the direction of the rotary axis (D), wherein the flange ( 2 ) includes a sealing lip ( 2 i ) projecting towards the axis of rotation (D) which forms the inlet opening ( 2 p ) extending concentric to the axis of rotation (D), wherein the rotary closure ( 3 ) has a spigot ( 3 a ) arranged concentric to the axis of rotation (D) which is arranged in the outflow direction after the inlet opening ( 2 p ) and wherein the spigot ( 3 a ) and the sealing lip ( 2 i ) are designed mutually matched so that the spigot ( 3 a ) which can be displaced in the direction of the axis of rotation (D) can adopt at least two positions, a closed position (SS) in which the spigot ( 3 a ) contacts the sealing lip ( 2 i ) so that the inlet opening ( 2 p ) is closed and an open position (OS), in which the spigot ( 3 a ) is spaced from the sealing lip ( 2 i ) so that the inlet opening ( 2 p ) is opened.
