摘要：
A syringe that includes a syringe barrel (16), a piston rod (14) and a cap (12), the cap (12) comprising: a main body portion (24) defining an open rear end configured to receive the piston rod (14), the main body portion (24) made of a rigid or rigid polymeric material, in which, when the fluid pressure inside the syringe barrel (16) is increased during an injection, The following actions occur: a) a flexible roof of the main body portion (24) is configured to expand in a radial direction towards an inner wall (38) of the syringe barrel (16)； b) a first perimeter skirt (36) extending around an outer circumference of the main body portion (24) is configured to be forced against the inner wall (38) of the syringe barrel (16)； characterized in that the material of the main body portion (24) has an elastic modulus in the range of 0.01 GPa to 5 GPa； and because with actions a and b the following action also occurs: c) a coupling between the piston rod (14) and a coupling portion provided along an internal circumference of the main body portion (24) is configured to force the main body portion (24) to expand in the radial direction towards the inner wall (38) of the syringe barrel (16), the coupling portion comprising a notch (44) comprising an upwardly angled portion ( 46) and a portion in descending angle (48).Una jeringa que incluye un cilindro de jeringa (16), un vástago de émbolo (14) y un tapón (12), comprendiendo el tapón (12): una porción de cuerpo principal (24) que define un extremo trasero abierto configurado para recibir el vástago de émbolo (14), la porción de cuerpo principal (24) fabricada de un material polimérico semirrígido o rígido, en la que, cuando se aumenta la presión de fluido en el interior del cilindro de jeringa (16) durante una inyección, se producen las siguientes acciones: a) un techo flexible de la porción de cuerpo principal (24) se configura para expandirse en una dirección radial hacia una pared interna (38) del cilindro de jeringa (16)；
