I want to design a small cylinder(approx. 7cm round)or rectangular (approx 24x8x4 cm) scent dispenser made for the outdoors. It will need to have a top similar to a mushroom to keep out sunlight and rain, also it will need a wick like system at the bottom on the inside and one that can be replaceable, yet the dispenser cannot leak. It will need a filler hole or shout to refill with desired liquid. It will also need a form of having it elevated above ground at different heights, either by being hung, or something more stable. The unit will probably be constructed by a nice finished metal or if demand is high enough a mould would be made.
Keep in mind this would be placed in yards near gardens and flower beds, as well as yard perimeters, so it needs to be slightly tasteful, but yet universal to meet most peoples taste in yard ornaments if you will.
