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.

Claims

1. In a two-component package having a cup arranged in a neck of the package to receive one component, and a screw cap, said cup defining an intended break line thereon, said cap cooperating with the neck of the package and having a collar which extends into the cup, said collar defining an abutment edge at the front end thereof, said cup cooperating with said cap in a basic sales position, said abutment edge disposed for separating the cup in the region of said break line upon a screwing of the cap beyond the basic sales position, the improvement comprising

said cup defines a cup wall, said wall having an annular step defined therein,

said step defining said break line spaced above the bottom of said cup,

said abutment edge of said collar being aligned with said annular step,

an inner surface of said cup wall has a bead inwardly directed therefrom, said bead disposed above said annular step engaging against an outer surface of said collar.

2. The two-component package according to claim 1, wherein

said cup has a frustoconical shape, at least below the annular step.

3. The two-component package according to claim 1, wherein

said package neck comprises a clip step, which clip step lies close to the mouth of said package neck, said cup wall being secured in said package neck by said clip step, the outer surface of the cup wall being arranged below the clip step at a distance from the inner surface of said package neck.

4. The two-component package according to claim 1, wherein

said package neck comprises a clip shoulder, said cap engaging behind said clip shoulder in the basic sales position, said cap being internally threaded wherein the lowermost lying region of said threads comprises individual thread projections, said projections located, with interruption, one behind the other in the circumferential direction.

5. The two-component package according to claim 4, wherein

said thread projections are of lenticular shape.

6. The two-component package according to claim 5, wherein

adjacent ones of said thread projections are disposed on the interior of said cap at different heights.

7. The two-component package according to claim 1, wherein

said abutment edge is located at a distance above the annular step in the basic sales position.

8. The two-component package according to claim 6, wherein

said package neck comprises a clip step, which clip step lies close to the mouth of said package neck, said cup wall being secured in said package neck by said clip step, the outer surface of the cup wall being arranged below the clip step at a distance from the inner surface of said package neck,

wherein said clip step and said clip shoulder are arranged approximately in the same cross-sectional plane.

9. The two-component package according to claim 1, wherein

said cup wall comprises two sections, said annular step being formed by a bridge between said two sections, which sections are spaced apart from each other in radial direction.

10. The two-component package according to claim 1, wherein

said collar is substantially cylindrical in cross section.

11. The two-component package according to claim 10, wherein

said cap further comprises a dispensing tube which tapers continuously to a free end thereof, said collar extended by said tube, said tube comprising an integral stopper attached by molding to said tube for closure of said tube.

12. The two-component package according to claim 1, wherein

said outer surface of said collar is sealed by said bead engaging thereagainst adjacent said abutment edge of said collar in said basic sales position.

13. The two-component package according to claim 1, wherein

said outer surface of said collar is cylindrical.
