| 摘要 |
The invention relates to a plunger-plug (10) made of an elastomer in particular, which comprises a cylindrical body (11) having a front axial side closed by a front wall (13), said hollow cylindrical body (11) comprising an external surface provided with at least one sealing profile (110), said front wall (13) comprising a front axial external surface (131) provided with a coating (135), advantageously a film made of ethylene tetrafluoroethylene (ETFE), said front wall (13) comprising, on the radially external edge thereof, a sealing profile (130), said front axial external surface (131) of said front wall (13) comprising a deformation profile (133) arranged radially inside said sealing profile (130) of said front wall (13), said deformation profile (133) being suitable for undergoing radial deformation in order to facilitate the insertion and/or the sliding of said plunger-plug (10) in a syringe body (1). |
