    • The pump is clamped to the top wall of a container closure by a pair of opposed, upper and lower clamping surfaces on the pump body which position the body to project down into the container. The lower clamping surface takes the form of a circular flange which is integral with the pump body and which is itself normally clamped between the top wall of the closure and the upper edge of the neck of the container when the neck is only slightly larger than the pump body, thereby preventing rotation of the body when the pump plunger is rotated to either lock or unlock the same from a fully depressed, stored position. When the pump is used on a large closure having a wide neck whose upper edge therefore fails to clamp against the pump flange, the pump body will nonetheless be held immobile by a series of flat surfaces therearound which matingly interlock with complimentally configured flat edges in the closure opening through which the pump body extends.
    • 泵通过在泵体上的一对相对的上,下夹紧表面夹紧在容器封闭件的顶壁上,该表面使得主体向下伸入容器中。 下夹紧表面采用圆形凸缘的形式,该圆形凸缘与泵体成一体,并且当颈部仅略大于盖体时,其本身通常夹在封闭件的顶壁和容器颈部的上边缘之间 泵主体,从而当泵柱塞旋转以防止其从完全压下的存储位置锁定或解锁时主体的旋转。 当泵用于具有宽的颈部的大型封闭件,其上边缘因此不能夹紧泵凸缘时,泵体将通过其周围的一系列平面保持不动,该平面与其中的相互配合的平坦边缘配合地互锁 关闭开口,泵体延伸穿过该开口。
