PURPOSE:To obtain a cylindrical container neck structure which can position a cap at a fixed rotating angle to a container body in the cap fastened state. CONSTITUTION:A screw part 23 to be fitted to a screw part 33 of a cap 30 is formed on the outer surface of a cylindrical neck of a container. An upper end surface is formed on the upper end of the container so as to be vertical to the axial direction of the cylindrical neck. In the neck 21, the screw part 23 is integrally formed with the upper end surface by molding. A top plate of the cap 30 and the upper end surface of the neck 21 collide with each other in the axial direction of the container by screwing the cap. At this time, the screwed cap is stopped. |
