Abstract
A tube style cosmetic container structure includes a tube having an opening arranged axially at one end. An axle sleeve is connected to the tube by being sleeved inside of the opening. A hollow piston rod includes a flanged disk arranged at the outside. A spring is placed against an end surface formed by a holding space of the axle sleeve and the hollow rod piston. A hollow sleeve pipe is firmly sleeved in the snatch part of the hollow piston rod. A hollow pencil pipe is sleeved by the hollow sleeve pipe and snatched by the protruding part of the hollow piston rod. An exterior cap can be screwed on the threaded part at the tube opening. When the exterior cap is screwed on, the material discharge hole can be wholly blocked, and no liquid will flow even if the tube is under certain pressure. When the exterior cap is screwed off and the tube is squeezed to force the contents out, no squeezed contents will backflow even if the pressure is reduced or stopped.
