Shower dispenser container-receiver coupling system
First Claim
1. A shower dispenser container-receiver coupling system comprising:
- 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.

Abstract
A system is described for connecting a bottle to a shower dispenser, which enables connection with only a small angle of turning, which latches the bottle in position while permitting detachment, and which avoids leakage of material during dispensing. The bottle, or container, has a cam on its neck, and the shower dispenser receiver into which the container can be screwed has a slot forming a detent that is deflected by the cam as the container is turned, to resist unscrewing of the container. The bottom of the slot that forms the detent, also forms a stop that prevents further screwing in of the container. The receiver has an internal cylindrical projection that is closely received within the container neck, and which substantially abuts an internal flange within the container, to minimize leakage of liquid during dispensing.
