Document Type and Number:
WIPO Patent Application WO/2008/065879
Kind Code:
A1
Abstract:
A chemical liquid container having a container body (1), a cap (2), an intermediate
member (3), and an intermediate plug (4). The cap (2) is provided with a chemical
liquid discharge path (25) and an air introduction path (28). The intermediate
member (3) has a tube body (35) projecting toward the inside of the container body
(1). A hydrophilic filter (29) is provided between a chemical liquid introduction
path (34) and the chemical liquid discharge path (25), and a filter (37) is provided
between an air supply path (36), communicating with the air introduction path
(28), and an air delivery path (43). The air delivery path (43) communicates
with the inside of the container body (1) via a check valve. The inner peripheral
surface of an annular valve (42) forming the check valve is in contact with the
outer peripheral surface of the tube body (35), and the check valve allows airflow
only in the direction toward the inside of the container body (1). The check valve
of the chemical liquid container can be easily produced and can reliably prevent
backflow of the chemical liquid.
