Anyone have any idea how to get access to the resin in this cart?

I dropped the cart and it broke. It still has a bunch left inside it so id hate to throw it away. But no matter what i try i cant get the top off. Ive tried twisting it, pulling straight off and even heating it up with a blowdryer first, it wont budge. Was thinking about maybe just cutting the top off but idk how id stop anything from getting mixed in with the resin.
