Liquid container

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 ( 12 a ) 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 ( 14 a ) to oppose each other.

1 . A liquid container comprising: a container body which has a tubular neck portion and a nozzle portion integrally provided on a top end of the tubular neck portion; and a top-closed tubular cap having a sealing portion to seal a nozzle hole of the nozzle portion, said cap being attachable to the container body to cover the nozzle portion and the tubular neck portion, characterized in that:
 the container body is configured such that the tubular neck portion is formed to have an outer diameter dimension greater than a maximum diameter dimension of the nozzle portion, and a protrusion for locking the cap is provided on an outer peripheral surface of the tubular neck portion; and   the cap has a pair of lockable pieces provided on an inner top region thereof to extend along the tubular neck portion and arranged in a diametral direction of the tubular neck portion, the cap being adapted to be locked with respect to the container body, in such a manner that, during an operation of attaching the cap to the container body along an axial direction of the tubular neck portion, the tubular neck portion is inserted between the lockable pieces, and the locking protrusion is inserted into a pair of locking concave portions formed in respective opposing surfaces of the lockable pieces,   wherein the lockable pieces have respective guide surfaces which are adapted, during the operation of attaching the cap to the container body, to come into contact with the outer peripheral surface of the tubular neck portion to guide the cap along the tubular neck portion so as to allow the nozzle hole and the sealing portion to become opposed to each other.   
     
     
         2 . The liquid container as defined in  claim 1 , characterized in that the guide surface of each of the lockable pieces has a shape which corresponds to a cross-sectional shape of the outer peripheral surface of the tubular neck portion so as to allow the guide surface to come into contact with the outer peripheral surface continuously in a circumferential direction thereof. 
     
     
         3 . The liquid container as defined in  claim 1 , characterized in that the guide surface of each of the lockable pieces is formed to come into contact with the outer peripheral surface of the tubular neck portion intermittently in a circumferential direction thereof. 
     
     
         4 . The liquid container as defined in  claim 1 , characterized in that the nozzle portion has a ring-shaped protrusion formed on an outer periphery thereof as a portion having the maximum diameter dimension.
