摘要

The container, comprising a body that is closed at one end and open at the other, has a cap connected to its open end, and a snap lock (8) that is closed once the container has been filled and cannot be opened without leaving an indication. The lock consists of a snap fastening (9) in a recess (10) in a crown ring (7) round the outside of the container's open end, and connected to the crown ring with breakable fixing points. The lock is held horizontally by the fixing points before it is opened and vertically after opening, clearly indicating that it has been used.
