Abstract

L'invention concerne un bouchon, en particulier un bouchon de seringue servant à obturer de manière étanche un orifice distal (4), par exemple un cône de seringue, d'un corps de seringue. Le bouchon, en particulier le bouchon de seringue, comprend un élément de fixation (3) qui est ou peut être disposé sur le corps de seringue autour de l'orifice distal, en particulier autour du cône de seringue, en particulier un raccord luer lock ou un adaptateur luer lock (3.1), et un capuchon (20) qui obture de manière étanche l'orifice distal, par exemple le cône de seringue, et qui est relié de manière amovible à l'élément de fixation. L'invention est caractérisé en ce que le capuchon est relié dans la zone de l'élément de fixation par liaison de matière, de préférence exclusivement par liaison de matière, à l'élément de fixation, en particulier au raccord ou à l'adaptateur luer lock, par au moins un point de jonction ou une surface de jonction, et en ce que le capuchon comprend une zone dure (30) et une partie en élastomère (10), la partie en élastomère obturant de manière sûre l'orifice distal, en particulier uniquement en appuyant sur ou en entourant un court segment dans la zone d'une pointe de l'orifice distal.
