There is no way to disarm trapped containers, Ark. Either do what Raze suggested - or get your fire res. very high or your HP (at fire res. 21 and low survival I found out, this trap takes 433 HP)
The best is this => save before you open a wine chest. These darn things tend to be trapped in a hideous way, same goes for the Shaman chest in his house.
You can only disarm traps you see on the ground => in Act 2 I took this skill at lvl 3 (detect at lvl 3, too) - a cheaper way is to let your summ. dolls run through in single mode. Yes, they die, but you don't need skill pts.
