ABSTRACT:
A sterile package for liquid and semi-liquid fluids comprises a container (1) containing the product to be dispensed (2). It is hermetically sealed by a breakable membrane seal (3) until first use, and includes an axial tube (4) extending from below the seal down to the bottom of the container (1). A dispensing head or cap (5)is fixed onto the neck (12) of the container and comprises a manually actuated member (6) for perforating the seal and for putting the dip tube into communication with a dispensing passage (7) which extends through the cap. The perforating member (6) is tubular, sliding axially and telescopically at one end of the dispensing passage (7). It comprises a snap-engagement mechanism (8) co-operating, at the end of its travel and after perforation of the seal (3), with complementary snap-engagement mechanism (10) on a fixed element of the package to cause the perforating member (6) to engage with the dip tube (4) in a positive sealing manner.
