Instead of making your bin leaky
you could utilise the same effect swordsmiths go for when they put a groove down the blade, to let air back in, lay a smooth stick down the side of the bin to stop the liner sticking to the bin all the way around and making the seal. One could get fancy and use a rope, chain, hose, bunch of figurines, taxidermied albatross, etc.
You could also just put the hole a little bit to up the side of the bin, so it'll still hold liquid.
