A roller bottle is provided with a bottom wall, a top wall and a cylindrical side wall extending between the bottom and top walls. The top wall includes an opening to provide access to the interior of the roller bottle. The cylindrical side wall of the roller bottle is formed with at least one spiral pleat extending substantially from the bottom to the top for increasing cell growth surface area and for facilitating the flow of liquid to all interior surface areas of the bottle as the bottle is rolled about its longitudinal axis.
