ABSTRACT:
A film-processing device comprises a lid having mounted therein a plunger or the like, which plunger is required to be rotatable in either direction in the lid and which is also required to be locked stationary in the lid. The plunger is connected with a cap which fits over the lid and which rotates with the plunger. The cap has a slidable member mounted thereon or therein with at least one detent member mounted on its underside so that, in one position of the slidable member, the cap is able to rotate on the lid, but in another position of the slidable member, the detent member thereon acts with an abutment member or members on the lid to disable the cap from rotating on the lid.
