Title
(EN) MEDICAMENT DELIVERY DEVICE
(FR) DISPOSITIF D'ADMINISTRATION DE MÉDICAMENTS
Abstract
(EN) A medicament delivery device comprising: a first component (7), and a second component (5) arranged concentrically with the first component (7), wherein the second component (5) is configured to move axially relative to the first component (7) from a first position to a second position, wherein one of the first component (7) and the second component (5) has a radially extending flash (7a), wherein the other one of the first component (7) and the second component (5) has a chamfer (5b) aligned with and facing the flash (7a) when the second component (5) is in the first position, and wherein one of the chamfer (5a; 5'a) and the flash (7a; 7'a) is configured to contact and subsequently pass the other one of the chamfer (5a; 5'a) and the flash (7a; 7'a) when the second component (5; 5') is moved from the first position towards the second position to thereby facilitate movement of the second component (5; 5').
(FR) L'invention concerne un dispositif d'administration de médicaments comprenant : un premier composant (7) et un second composant (5), disposé de manière concentrique par rapport au premier composant (7), le second composant (5) étant configuré pour se déplacer axialement par rapport au premier composant (7) d'une première position à une seconde position, le premier composant (7) ou le second composant (5) comportant un bourrelet (7a) s'étendant radialement, l'autre composant (7) ou le second composant (5) comportant un chanfrein (5b) aligné avec le bourrelet (7a) et faisant face à celui-ci lorsque le second composant (5) se trouve dans la première position, et le chanfrein (5a ; 5'a) et/ou le bourrelet (7a ; 7'a) étant configuré pour entrer en contact avec l'autre élément parmi le chanfrein (5a ; 5'a) et le bourrelet (7a ; 7'a) et le dépasser ensuite lorsque le second composant (5 ; 5') est déplacé de la première position vers la seconde position pour faciliter ainsi le mouvement du second composant (5 ; 5').
