摘要

The plastic cover (3) for extraction of liquid holds airtight both a container (1) for the liquid and a piercing element (2) with a section of hose for extraction and delivery of the liquid. Through preliminary sterilization (by means of ionizing rays, for example) of the cover together with its contents, subsequent extraction of the liquid under sterile conditions is made possible.
