<p>The invention relates to a capsule (1) for the security closure of containers. It is usefully applied in the field of diagnosis and especially on containers full of a chemical reagent into which a sample of a substance to be analysed is injected. The capsule (1) is provided with a cap (2) having at least one portion (3) made of a material which can be pierced by a syringe needle. The portion (3) is covered by a cover (4). The cap (2) is associated to a first security ring (5) such as to detach from the cap (2) following a raising of the cap (2) in an axial direction to the container. A second security ring (6) is associated to the cover (4) in such a way as to detach therefrom following a raising of the cover (4) so as to uncover the pierceable portion (3) and permit a needle to be introduced into the container.</p> |
