PCT No. PCT/EP88/00026 Sec. 371 Date Nov. 9, 1988 Sec. 102(e) Date Nov. 9, 1988 PCT Filed Jan. 15, 1988 PCT Pub. No. WO88/06129 PCT Pub. Date Aug. 25, 1988.The invention relates to a closure cap for a bottle or like containers, having an internally-threaded cylindrical part for screwing onto an externally threaded bottleneck, and with a sealing member, separate from the cylindrical part and connected to the cylindrical part, being provided with an annular sealing surface to abut upon the mouth of the bottleneck. The sealing member pivots around a rotational axis which is located in a plane perpendicular to the axis of the cylindrical part, and located radially inwards of the annular sealing surface. By unscrewing the screw-type closure cap, the disc-like sealing member tilts, thus allowing the contents of the bottle to be poured out without the screw-type closure cap being completely screwed off. Thus, the cap is prevented from falling down and being soiled, or from getting lost. By opening the screw-type closure cap to different extent, it is, moreover, possible to adjust the cross-section for the outflow and, thus, to control the quantity delivered. |
