Abstract

A liquid container has a body (1) and a cap (2). A circular tubular neck (12) of the body (1) has an outer diameter greater than a maximum diameter of a nozzle (14), and a locking protrusion (124) for the cap (2) is provided on an outer peripheral surface of the circular tubular neck. The cap (2) has two lockable arms (24). The lockable arms (24) are locked onto the locking protrusion (12a) while attaching the cap (2) to the body (1). Opposing surfaces (26) of the lockable arms (24) define guide surfaces that contact the outer peripheral surface of the circular tubular neck (12) during the cap attaching operation to guide the cap (2) along the circular tubular neck (12) so as to allow a plug protrusion (22) of the cap (2) and a nozzle hole (14a) to oppose each other.
