Title:
Liquid discharge vessel
Document Type and Number:
Japanese Patent JP6125150
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a liquid discharge container capable of preventing any trouble in the liquid-tight contact with a container body by thermal expansion deformation or shrinkage return of a piston, reliably preventing any liquid leakage by constantly maintaining the liquid-tight contact state of the piston with the container body, and guaranteeing smooth vertical motion of the piston.SOLUTION: In a liquid discharge container 1, a liquid discharging pump 9 is provided on an upper section of a container body 2 for storing liquid. A piston 7 for preventing any liquid leakage is provided on a bottom part in the container body 2 in a vertically movable manner according to a pressure difference between inside of the container body 2 and the outside thereof. An annular regulating body 8 having the same coefficient of thermal expansion as that of the container body 2 is provided on the inner side of an upper end projecting edge 7b of the piston 7 in liquid-tight contact with the container body 2.
