If you need more containers, Tim Hortons give away for free their containers that held the fondant. I have a few of those, I use them for collecting the sap from the tree containers.
For on the trees I use ice cream containers that you get from the stores that sell ice cream cones. Those ones don't have lids but I sit them on the ground or inside a non food grade 5 gallon pail. The nice thing with the ice cream container is that the lid comes off easy for dumping out the sap. I drill a hole tight to the diameter of the tube and don't get water and garbage in my sap.
