(57) Abstract

[Object] It is an object of the present invention to provide a liquid medicine supply device configured to reliably prevent infants and children from accidentally opening the liquid medicine supply device. [Solutions] A liquid medicine supply device ( 1 ) including a container ( 10 ) with a containing portion ( 11 ) and a mouth ( 16 ); an interior cap ( 30 ); and an exterior cap ( 60 ), in which the interior and exterior caps ( 30, 60 ) include a ratchet mechanism ( 50, 80 ). The ratchet mechanism allows the exterior and interior caps ( 60, 30 ) to be integrally rotated when the exterior cap is rotated relative to the mouth under a condition of the exterior cap ( 60 ) pressed against the interior cap whereas the ratchet mechanism allows the exterior cap ( 60 ) to be rotated relative to the interior cap ( 30 ) when the exterior cap is rotated relative to the mouth under a condition of the exterior cap ( 60 ) which is not pressed against the interior cap. An axial direction of the mouth ( 16 ) is inclined from an axial direction of the containing portion ( 11 ) at a predetermined angle (θ).
