Abstract

An object of the invention is to measure out precisely the liquid to be poured out and applied, to safely achieve the firm assembly of components and to obtain effective function of displays. An applying stopper (1), which changeovers communication of a measuring chamber (A) formed by rotational operation between a bottle unit (8) and a pouring out mouth (55), is attached to a bottle unit (8). The measuring chamber (A) is structured by parts that cannot be deformed. Inseparable assembling of an attaching unit (2) and a switching unit (4) of the applying stopper (1) is achieved by bending displacement of engagement coupling function parts. An assembling position of the applying stopper (1) with respect to the bottle unit (8) in the circumferential direction is aligned.
