<P>PROBLEM TO BE SOLVED: To easily assemble a liquid spray container and to manufacture it at a low cost after suppressing collision sound and impacts generated when an elevated plunger is lowered to the lowest limit position. <P>SOLUTION: The liquid spray container 1 includes: a container body; a cylinder 20 fixed to the container body; a turning ring turnably attached to the cylinder; a discharge pipe attached to the turning ring; a plunger liquid-tightly and externally fitted to the discharge pipe, provided so as to be vertically moved and energized downwards; a conversion mechanism for converting the rotation of the turning ring to the elevation of the plunger; a spray head capable of spraying liquid contents by being pressed; a liquid pressure release path 91 and an air inflow path 92 provided between the cylinder and the plunger; an equal pressure hole 27 for communicating the container body and the liquid pressure release path; and an equal pressure valve 80 for opening and closing the equal pressure hole and opening and closing the space between the liquid pressure release path and the air inflow path. A buffer part 89 to be abutted to the plunger from below when the plunger is positioned at the lowest limit position inside the cylinder is formed integrally on the equal pressure valve. <P>COPYRIGHT: (C)2010,JPO&INPIT |
