Abstract
A bottle closure cap for two-component packings having a collar which extends into the bottleneck and bears a beaker via a thread of opposite direction to the bottle screw-on thread. For ease in manufacture and use, the invention proposes that the collar (9) which extends into the bottleneck continue on top in a collar wall (11) with internal thread (14) in order to receive and hold a lid (28).
Claims6
A bottle closure cap for a two-component packing containing a first component and a second component, wherein the two-component packing comprises a bottle for receiving the first component and the closure cap for receiving the second component, the bottle having a neck and screw-on thread threaded in a first direction for receiving the closure cap, the closure cap having a screw-on thread threaded in said first direction for attachment to the screw-on thread of the bottle, the closure cap comprising:
- a collar having an inner portion which extends into the neck of the bottle upon attachment of the cap to the screw-on thread of the bottle, the cap screw-on thread being located on said collar;
- a cover to be received by a first end of said collar distant from said inner portion of said collar, and a beaker supported by said inner portion of the collar for receiving the second component, the beaker connecting with the collar via a thread which is threaded in a second direction opposite to said first direction of the bottle screw-on thread, the beaker being located within the bottle upon attachment of the cap to the bottle;
- wherein said inner portion of the collar has a wall of reduced diameter for extending into the bottle neck, the collar including a transition zone and a cylindrical wall of larger diameter, said cylindrical wall of larger diameter extending between said transition zone and said first end of said collar;
- the reduced-diameter wall passes outwardly via the transition zone into the cylindrical collar wall of larger diameter, the collar with its reduced-diameter wall and its larger-diameter wall defining a receiving space for storing of the second component;
- the receiving space is closable on said first end of said collar opposite the beaker by the cover, the cover being disposed on the larger-diameter wall of the collar;
- and
- said collar wall of larger diameter has form-locking means for inhibiting an unscrewing of said cover from said collar.
