  • a shower dispenser receiver having walls forming an opening and a thread inside the opening; and

    a container having a neck that can be received in the receiver opening, a thread on the neck that mates with the receiver thread, and a cam;

    the walls of said receiver that form said opening, forming a resilient detent located in the path of said cam as the container is turned to screw the container thread on the receiver thread, said detent positioned so that as the container is screwed in the detent is first deflected out of the way of the cam and then released to lie behind said cam to resist unscrewing of the container, said receiver walls also forming a stop that prevents substantial further container rotation past the position at which the detent is released.
