Claims

[Scope of utility model registration request]

A bottle body consisting of an inner cylinder that can store fluid and an outer cylinder that covers the inner cylinder, a guide cylinder part that is fitted into an opening at the upper end of the inner cylinder and has a guide hole that penetrates vertically, and an external cylinder. a stopper having a communicating passage; a lid body attached to the outside of the stopper fitted in the inner cylinder; and a lid body that is loosely inserted into the guide hole of the guide cylinder so as to be movable in the vertical direction, and a lower side. A valve stem having a valve seat portion at the top, a biasing member stop attached to the upper part of the valve stem, and a biasing member stop interposed between the biasing member stop and a groove on the outside of the guide cylinder portion, and a biasing member that biases the plug upward to close the passage of the plug with the valve seat, so that the passage of the plug is opened when the lid presses down the valve stem. In the thermos flask, a tapered portion is provided on the outer surface of either one of the lower surface of the biasing member stop and the upper end of the guide cylinder portion that surround the valve stem, and the tapered portion is provided on the inner surface of the other one. another tapered portion into which the tapered portions can be fitted is provided, a ring-shaped gasket is provided on one of the ends of these tapered portions, and when the passage of the plug is opened, the two tapered portions are fitted into each other. A thermos flask, characterized in that the gasket is liquid-tightly clamped between the tapered portions.
