<p>The mixing assembly (100) consists of a stopper (14) in a hole (11) in the neck of a first container (1) and a coupling (61) in the neck (53) of the second container made with inner surface lugs (68) which engage with projections (18) on the stopper and extract it from the first container when it is inverted over the second one. The extracted stopper drops into the second container, allowing the products to mix.</p> |
