I throw my packer, medicine spoons, eye droppers, tubing, and other stp related materials in a drawstring backpack, but you said you don't have one o.o
Ask a friend to hold your stuff? Put it in a pillowcase/garbage bag and put it in the attic or basement or even your garage, hell maybe even bury it if push comes to shove(layer it in bags and stuff though)! Do what you gotta do.
