Abstract

It is constructed such that a closed space (12b) of an inner container (12) having a heat retaining property which constitutes a liquid container (1B) is able to be closed airtightly by closing of a lid structure (141). Contact between stored liquid and the atmosphere is shut off by making the inside of the closed space be in an inert gas atmosphere. It is constructed such that the stored liquid is able to be discharged by pressure of supplied inert gas at a time of opening of a discharge valve (168) communicating with the inner container. Oxidation deterioration of liquid is effectively prevented by shut-off from the atmosphere. When the stored liquid is discharged in small portions, preventive effect is maintained by continual supply of inert gas.

Claims9

Dependent claims

A liquid container comprising:

an outer container;
an inner container having a heat retaining property which is housed in said outer container;
a lid structure capable of forming a closed space in said inner container by closing an upper opening of said inner container airtightly in an openable/closable manner;
a gas supply means for supplying inert gas of a predetermined pressure into the closed space of said inner container;
a valve structure enabling the closed space of said inner container and the outside to be communicated;
a draw pipe for guiding liquid stored in said inner container to out of said outer container via the closed space;
and
a discharge valve provided to said draw pipe;
wherein it is constructed such that the stored liquid is able to be discharged by pressure of supplied inert gas at a time of opening of said discharge valve.
