Zusammenfassung:	The present disclosure relates to a piston configured for use with a dispensing syringe and a dispensing syringe having the same. The piston has a body configured to be slidably positioned within an internal reservoir of the dispensing syringe. The body defines a wall circumferentially surrounding the piston. The piston also has a wiper seal extending outwardly and circumferentially from the wall. The wiper seal defines a lip, a first portion, a second portion, and a joint connecting the first portion and the second portion. The second portion extends outwardly from the joint and away from the body to the lip. 本公开涉及一种配置成与分配注射器一起使用的活塞和具有该活塞的分配注射器。活塞具有主体，该主体配置成可滑动地定位在分配注射器的内部贮存器内。主体限定周向地包围活塞的壁。该活塞还具有从该壁向外且周向延伸的擦拭器密封件。该擦拭器密封件限定唇缘、第一部分、第二部分以及连接第一部分和第二部分的接合部。第二部分从接合部向外并且远离主体延伸到该唇缘。
