This is the original "throwing" canister created for the lab scene in TMNT II in which the canister is being thrown between the Foot Clan & the Turtles.
This particular canister was actually created the day of filming due to the lack of a canister being made for specifically for throwing and therefore doesn't include the wide metal paneling for the TGRI decal.
This was meant for quick shots where detail didn't matter.
