Bi-injection molded housing of a locking cap for a pharmaceutical vial, and locking cap including such a housing

A locking cap for a pharmaceutical vial, comprising:

• a bi-injection molded housing, including:
• a first material forming an upper ring, legs having upper ends rigidly connected to the upper ring, and bridges connecting lower ends of the legs in pairs, at least some bridges comprising a flexible tab configured to engage under a flange of the vial, and
• a second elastomer material forming a stopper configured to seal the vial when the flexible tabs engage under the flange,
• wherein at least one inner face of the upper ring made of the first material is rigidly connected to the stopper made of the second material, and
• wherein the stopper comprises a head rigidly connected to an inner face of the upper ring, and the head of the stopper comprises at least one recess and at least one shoulder that are complementary to at least one shoulder and at least one recess defined on the inner face of the upper ring and/or of the legs;
• an external body that surrounds the housing and is fixed thereto, the external body comprising an opening in an upper face of the external body, the opening being centered on and surrounding a central hole of the upper ring of the housing;
• and
• a capsule held on an upper face of the outer body for closing the opening and preventing access to the stopper.
