A process and apparatus for forming a leak proof body (16) and cap (18). The process including the steps of defining a mold cavity (10) between a first mold part and a second mold part, injecting a molten material into the mold cavity thereby forming from the molten material a body (16) and cap (18), and retracting the first mold part from the second mold part to separate the first mold part from the body and cap. Thereafter, engaging at least the body with a robotic arm (112) and moving the body with the robotic arm into a capping device (14) while the body and cap are at a temperature at which the material is not fully set. The body is then sealed by moving the cap into engagement with the body to form a leak proof seal.

L'invention concerne un procédé et un appareil permettant de former un ensemble étanche corps (16) et couvercle (18). Ce dit procédé comprend les étapes consistant à définir une cavité de moule (10) entre une première partie de moule et une seconde partie de moule, à injecter un matériau en fusion dans la cavité de moule et à former ainsi un corps (16) et un couvercle (18) constitués du matériau en fusion, puis à retirer la première partie de moule de la seconde partie de moule pour séparer la première partie de moule de l'ensemble corps et couvercle. Ensuite, ledit corps est mis en contact avec un bras manipulateur (112) à l'aide duquel il est amené dans un dispositif de mise en place de couvercle (14), le corps et le couvercle étant alors à une température à laquelle le matériau n'a pas complètement durci. Le corps est ensuite fermé par emboîtement du couvercle sur celui-ci, ce qui crée une fermeture étanche.
