Abstract: A bottle closure cap for two-component packages is formed with a collar extending from the bottom of a cup-shaped cap which has a bottle screw-on thread on the inner wall of the cup. The collar connects via a thread which is directed opposite the bottle-screw-on-thread, to a beaker which can be brought over projections seated on an outer side of its beaker cylindrical wall into a non-rotatable but axially displaceable coupling engagement with the inner wall of a bottle neck. A front end of the collar comes into form-locked engagement by an annular groove on the bottom of the beaker.

Abstract: There is provided an attachment having a pot-shaped bottom element and a sealing cap adapted to be arranged on the neck of tubes, bottles or the like. The top side of the ceiling of the bottom element, which is supported by the side wall of the pot-shaped bottom element, is fitted with brush-like bristles which are covered by the sealing cap. The central region of the bottom element ceiling is provided with an orifice into which projects a tongue extending from the bottom side of the sealing cap, the free end of the tongue entering the orifice in the ceiling of the bottom part and sealing the same in the manner of a plug.

Abstract: A container for holding contents as two separate components which can be mixed together later. The container comprises a cup positioned in a neck of the container for receiving a first of the components; a screwcap coordinated with the neck of the container and having a collar extending into the cup, a front edge of said collar forming a strike edge for separating the cup in the region of a line of intended breakage upon a further screwing on of the screwcap beyond a basic position for storage; and a wall of the cup has an annular step, and the strike edge of the collar comes flush on the annular step on the wall of the cup, the step--forming the place of intended breakage--being located at a distance above the bottom of the cup, there being a bead extending towards an outer surface of the collar and projecting inwardly from the inner surface of the wall of the cup, the step lying below said bead; and a clip shoulder is disposed on the collar and engages the bead of the cup wall.

Abstract: A two-component package comprises a cup arranged in a neck of the package to receive one component, and a screw cap. The cup defines an intended break line and cooperates with the neck of the package. A collar which extends into the cup, defines an abutment edge at the front end thereof. The abutment edge is disposed for separating the cup in the region of said break line upon a screwing of the cap.The cup defines a cup wall and an annular step therein.The step includes the break line spaced above the bottom of the cup.An inner surface of the cup wall has a bead inwardly directed therefrom. The bead disposed above the annular step engages against an outer surface of the collar.
