Abstract

A packaging container includes a tube body, a tube head, a roller applicator, and a cover. The tube head is connected to one end of the tube body, and the roller applicator is arranged on the tube head. When not in use, the cover may cover the tube head, and the blocking portion of the cover seals an orifice of the tube head to prevent inner material from leaking. When in use, the contact area between the roller applicator and the skin may reach more than 65%, which provides an improved massage effect.
