An improved locking arrangement for a tampon applicator of the type employing inner and outer tubes with a tampon seated in the outer tube and in which the inner tube is telescopically movable to eject the tampon or similar ejectable element. The improved arrangement temporarily locks together the inner and outer tubes to prevent premature separation during handling and processing. The locking arrangement is formed by punching through the wall of the outer tube, in an area where the inner and outer tubes overlap, an aperture defining at least one forward pointing, downwardly bent, triangular-shaped tab with a convex base depending from a concavely arcuate hinge line. The concavely arcuate hinge line from which the convex base the triangular-shaped tab downwardly depends, provides a stable construction which prevents the tab from losing its downward bend, due to its natural resilience until the tubes are manually pushed together by the user to eject the tampon. The aperture forming the locking arrangement may be circular and define a plurality of downwardly bent triangular segments with their convex bases and concavely arcuate hinge lines collectively forming the circumference of the aperture. |
