warehouse, storehouse
庫 centers on a covered space for storing goods: a warehouse or storehouse where items are kept safe.
庫 combines 广 (building with a roof) and 車 (vehicle), originally referring to a garage or shed for chariots, later extended to any storehouse.
Under a roof 广, a vehicle 車 is parked. Imagine a large garage-like warehouse where carts and goods are stored.
For コ, picture a storehouse full of cocoa beans: cocoa -> コ, and the warehouse keeps them safe.
