LIQUID CONTAINER AND DIAPHRAGM VALVE

摘要

A liquid container using a diaphragm valve having a diaphragm-like section. The diaphragm valve may consist of elastomer. Also, the diaphragm valve may include n number (n being an integer of two or greater) of engaging sections engaging with a diaphragm supporting section. Further, the diaphragm-like section may be fixed to a position closer to a first seal surface of a seal section than a second seal surface of the seal section. The area of contact between the first seal surface and a first member is greater than the area of contact between the second seal surface and a second member. In a first case in which the diaphragm valve is placed on a first flat surface with an end of a projection facing the first flat surface, an end of a first support section is in contact with the first flat surface to support the diaphragm valve, and the end of the projection may be in contact with the first flat surface with the diaphragm-like section not deformed. Also, a projection inserted in the inner side of an end of a coiled spring may be mounted on the center axis side separated away from the range of a position at which the projection can make contact with the end of the coiled spring when the coiled spring moves in a recess in a direction perpendicular to the center axis of the coiled spring.
