Beschreibung
Zusammenfassung:	The present invention provides a heat insulating container (1) for low-temperature liquefied gas pumps, having: an inner tank (3) housing low-temperature liquefied gas; an outer tank (5) attached externally around this inner tank (3); and a low-temperature liquefied gas pump (2) arranged inside the inner tank (3). The outer tank (5) has: an upper outer tank (5U) in an upper end section side section thereof; and an outer tank main body (5L) being the section other than this upper outer tank (5U). A lid structure (6) is provided that has a heat-insulating structure and is detachably fitted into an upper side section of the inner tank (3). The lid structure (6) has a pump (2) fixed thereto and has a suction pipe (7) and a discharge pipe (8) inserted into and fixed thereto. A vacuum heat insulation layer (4) is provided between the inner tank (3) and the outer tank (5). The heat insulating container for low-temperature liquefied gas pumps has improved heat insulation properties in the lid structure and improved maintenance properties for the pump.
