Abstract
In one embodiment of a dispensing system for connecting a remote power sprayer to a container of liquid, a flexible delivery tube includes one end non-removably connected to a remote retainer and the other end non-removably connected to a connector hose. The remote retainer and connector hose each include strain relief elements which respectively include a retainer adaptor and a connector adaptor for relieving the connection strain between the tube, the remote retainer and connector hose, as the power sprayer is being pulled and maneuvered during use. In a second embodiment, the flexible delivery tube includes one end non-removably connected to a remote retainer and the other end disposed freely in a container, but plugged onto a connector hose and including a spring weight slidably disposed thereon.
