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.
Claims13
A container comprising a pair of facing flexible walls, one of said flexible walls including a nonuniformly roughened finish wall portion having a surface roughness with a mean depth exceeding about five microns, the other one of said flexible walls including a uniformly roughened finish wall portion which faces said nonuniformly roughened finish wall portion and which has a surface roughness with a mean depth greater than the mean depth of said nonuniformly roughened finish wall portion.
