Two-component packages
First Claim
1. A two-component package for storing two components which are to be isolated from each other during storage and mixed when the package is opened, the package comprising:
- a container to receive first component, said container having a threaded neck;
a threaded closure cap to close the threaded neck of the container;
a capsule to receive the second component, said capsule being located inside the container with an upper part of the capsule extending into the threaded neck of the container;
a first ratchet means extending inwardly from the closure cap;
a second ratchet means provided on the upper part of the capsule to engage said first ratchet means, whereby the closure cap can be screwed down without rotating the upper part of the capsule, but unscrewing the closure cap causes the top part of the capsule to rotate with the closure cap;
one or more rotation blocks provided on the outer wall of the capsule and on the inner wall of the container to impede rotation of the lower part of the capsule in the direction of unscrewing of the closure cap; and
release means provided on the capsule to release the second component from the capsule when the upper part of the capsule is rotated relative to the lower part of the capsule.

Abstract
Two-component packages for storing two components which are to be isolated from each other during storage and mixed when the package is opened. The packages comprise an outer container (2) for a first component having a threaded neck (3). A closure cap (5) is provided to close the threaded neck (3). A capsule (6) for a second component is located inside the outer container (2) and extends into the threaded neck (3) of the outer container (2). A first ratchet means extends downwardly from the base of the closure cap (5) and engages with a second ratchet means on the top part (7) of the capsule (6), whereby the closure cap (5) can be screwed down without rotating the said top part (7) of the capsule (6), but cannot readily be unscrewed without also rotating the said top part (7). A rotation block (13,14) prevents rotation of a lower part (11) of the capsule (6). As a result, unscrewing the closure cap (5) exerts a torsional force on the capsule (6). Release means (12), such as a screw thread, are provided in the capsule (6) to release the contents of the capsule (6) when the said torsional force is applied.
