Abstract
A container includes facing plastic wall portions, one having a nonuniform or irregular surface finish, the other having a uniform or regular surface finish. The two differing surface finishes each have a different mean depth. The juxtaposition of these unlike wall finishes reduces or eliminates the likelihood of the walls sticking or adhering together during surface contact. The container can undergo heat sterilization while empty without loss of function.
