A piercing assembly in the compartment of one part includes a blade member extending in a closed loop contiguously adjacent the circumferential wall of the one part and spacers interposed between the blade member and the bottom wall which is resiliently movable inward of the shell cavity for engagement with the spacers whereupon the blade member cuts the membrane.
