Abstract: Oriented pump having a push-member-distributor (3) axially and angularly movable including at least one lug (35) cooperative with a blocking ramp having an indexed abutment for preventing and allowing at will the depression of the push-member and the disengagement of the push-member from bearing on the head of the piston (2). The seal is maintained between the push-member and the rod of the piston in all positions and the push-member is axially retained independently of the piston. The push-member is oriented on the neck of a given container at will when assembling the pump.

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.
