Review on 🍬 CoaGu 8oz Sugar Canisters: Versatile Stainless Steel Lunch Containers for Child's Lunch, Tea, Sugar, Coffee, Candy by Shawna Williams

This is a difficult task; A very nice and strong cap with a proper gasket will not fit snugly enough on the canister body - less than 1/2 turn and it will pop open. I use this for a portable supply of various seeds and nuts so it works fine as long as I'm careful. The treads seen in the picture suggest significantly more intervention, which would be possible if the treads themselves protruded a few millimeters further. from the barrel of the neck to the canister. This would increase the degree of thread engagement. In any case, the friction of the rubber seal keeps the cap from falling off at a 1/4 or 1/3 turn. Good metal, easy to clean. Best suited for dry materials. I can try reconfiguring manually and see what happens.
