Closure caps for two-component packaging systems
First Claim
1. A binary package comprising a container having a threaded bottle neck (2) and adapted to receive a diluent, an inner container (5) forming a reservoir adapted to receive a concentrate (1) which is to be admixed in situ with said diluent, and a threaded closure cap threadedly engaging said bottle neck (2), said closure cap having a base, a bottle thread (17a) for engaging the bottle neck (2) and a collar (3) extending radially into the bottle neck (2) from the base of the closure cap, said collar having a collar thread (4) for receiving the inner container (5) and a lower end in the form of an abutment edge (7), the inner container (5) having a flat base (8) and having a weakened line (10), the bottle neck (2) and the inner container (5) both having inner and outer walls, the inner wall of the bottle neck (2) having at least one rotation block (6'"'"'), and the outer wall of the inner containers having at least one rotation block (6), said rotation blocks (6,6'"'"') cooperating between the outer wall of the inner container (5) and the inner wall of the bottle neck (2) to prevent free rotation of the inner container (5) in at least one direction of rotation, whereby when the binary package is closed the abutment edge (7) rests on the base of the inner container (5), and when the closure cap is rotated further in the direction of closure of the collar thread (4), the inner Container is severed along the weakened line(10).

- 1. A binary package comprising a container having a threaded bottle neck (2) and adapted to receive a diluent, an inner container (5) forming a reservoir adapted to receive a concentrate (1) which is to be admixed in situ with said diluent, and a threaded closure cap threadedly engaging said bottle neck (2), said closure cap having a base, a bottle thread (17a) for engaging the bottle neck (2) and a collar (3) extending radially into the bottle neck (2) from the base of the closure cap, said collar having a collar thread (4) for receiving the inner container (5) and a lower end in the form of an abutment edge (7), the inner container (5) having a flat base (8) and having a weakened line (10), the bottle neck (2) and the inner container (5) both having inner and outer walls, the inner wall of the bottle neck (2) having at least one rotation block (6'"'"'), and the outer wall of the inner containers having at least one rotation block (6), said rotation blocks (6,6'"'"') cooperating between the outer wall of the inner container (5) and the inner wall of the bottle neck (2) to prevent free rotation of the inner container (5) in at least one direction of rotation, whereby when the binary package is closed the abutment edge (7) rests on the base of the inner container (5), and when the closure cap is rotated further in the direction of closure of the collar thread (4), the inner Container is severed along the weakened line(10).
- 3. A binary package comprising a container having a threaded bottle neck (2) and adapted to receive a diluent, an inner container (5) forming a reservoir adapted to receive a concentrate (1) which is to be admixed in situ with said diluent, and a threaded closure cap threadedly engaging said bottle neck (2), said closure cap having a base, a bottle thread (17a) for engaging tee bottle neck (2) and a collar (3) extending radially into the bottle neck (2) from the base of the closure cap, said collar having a collar thread (4) for receiving the inner container (5) and a lower end in the form of an abutment edge (7), the inner container 55) having a flat base (8) having a weakened line (10) and having an annular bead (12) directed radially outwardly and abutting on the bottle neck (2), the annular bead (12) defining depth of suspension of the inner container (5) and blocking free rotation of the inner container (5), whereby when the binary package is closed the abutment edge (7) rests on the base of the inner container (5), and when the closure cap is rotated further in the direction of closure of the collar thread 94), the inner container is severed along the weakened line (10).
- 5. A binary package comprising a container having a threaded bottle neck (2) and adapted to receive a diluent, an inner container (5) forming a reservoir adapted to receive a concentrate (1) which is to be admixed in situ with said diluent, and a threaded closure cap threadedly engaging said bottle neck, said closure cap having a base, a bottle thread (17a) for engaging the bottle neck (2) and a collar (3) extending radially into the bottle neck (2) from the base of the closure cap, said collar having a collar thread (4) for receiving the inner container (5), the bottle neck (2) and the inner container (5) both having inner and outer walls, the inner wall of the bottle neck (2) having at least one rotation block (6'"'"') and the outer wall of the inner container (5) having at least one rotation block (6), said rotation blocks (6,6'"'"') cooperating the outer wall of the inner container (5) and the inner wall of the bottle neck (2) to prevent free rotation of the inner container (5) in at least one direction of rotation, where the collar thread (4) and the bottle thread (17a) have different directions of rotation.
