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.

What is claimed is: 1. An assembly for connecting a remote power sprayer to a container of liquid having a rigid dip tube, said assembly comprising: a retainer adapted to be coupled to the remote power sprayer; a connector hose; a flexible hollow fluid delivery tube having a first end coupled to said retainer and a second distal end coupled to said connector hose, and said connector hose adapted to be coupled to the container of liquid; and first and second strain relief means for respectively relieving connection strain between said first end of said tube and said retainer, and said second distal end of said tube and said connector hose; wherein said retainer includes a wall defining a first elongated opening therein, said first strain relief means includes a first tube retention device retained within said first elongated opening, and said first end of said delivery tube extends over said first tube retention device and is captured between said first tube retention device and said wall defining said first elongated opening. 2. An assembly according to claim 1, wherein: said first tube retention device comprises a nipple having ridges which dig into said first end of said delivery tube. 3. An assembly according to claim 1, wherein: said second strain relief means includes a second tube retention device. 4. An assembly according to claim 3, wherein: said second tube retention device is integral with said connector hose. 5. An assembly according to claim 3, wherein: said second strain relief means further includes a connector adaptor having a wall defining a second elongated opening, and said second end of said delivery tube extends over said second tube retention device and is captured between said second tube retention device and said wall defining said second elongated opening. 6. An assembly according to claim 5, wherein: said second tube retention device comprises a nipple having ridges which dig into said second end of said delivery tube. 7. An assembly according to claim 5, wherein: said connector hose includes at least one radially extending element which frictionally engages said connector adaptor. 8. An assembly for connecting a remote power sprayer to a container of liquid having a bottom surface, said assembly comprising: a retainer adapted to be coupled to the remote power sprayer; a connector hose; a flexible hollow fluid delivery tube having a first end coupled to said retainer and a second distal end coupled to said connector hose, and said connector hose adapted to be coupled to the container of liquid; a strain relief means for relieving connection strain between said retainer and said fluid delivery tube; and a weight provided adjacent said second distal end of said fluid delivery tube, said weight maintaining said connector hose adjacent the bottom surface of the container; wherein said retainer includes a wall defining an elongated opening therein, said strain relief means includes a first tube retention device retained within said elongated opening, and said first end of said delivery tube extends over said first tube retention device and is captured between said first tube retention device and said wall defining said elongated opening. 9. An assembly according to claim 8, wherein: said first tube retention device comprises a nipple having ridges which dig into said first end of said delivery tube. 10. An assembly according to claim 8, further comprising: a closure cap slidably disposed on said delivery tube and adapted to mount on the container of liquid. 11. An assembly according to claim 10, further comprising: an adaptor located between said closure cap and said connector hose, said adaptor having means for clamping onto said delivery tube. 12. An assembly according to claim 11, wherein: said weight is located between said adaptor and said connector hose. 13. An assembly according to claim 11, wherein: said delivery tube includes a notch, and said means for clamping are adapted to engage said notch. 14. An assembly according to claim 11, wherein: said connector hose includes a second nipple having ridges which engage said second end of said delivery tube. 15. An assembly according to claim 9, wherein: said connector hose includes a second nipple having ridges which engage said second end of said delivery tube. 16. An assembly according to claim 8, wherein: said weight is a spring which is slidable on said delivery tube. 17. An assembly according to claim 8, further comprising: a closure cap slidably disposed on said delivery tube and adapted to mount on the container of liquid; and an adaptor located between said closure cap and said connector hose, said adaptor having means for clamping onto said delivery tube.
