Claims

[Scope of utility model registration request]

(1) A transparent container that holds colored liquid up to a predetermined level line and is large enough to be held in both hands, an inner pipe that extends from the bottom of the container to above the mouth of the container, and a transparent container. a liquid riser pipe which connects two external pipes with upper and lower end pipe plugs in a reciprocal manner and forms a rising path gap for a colored liquid that communicates with the atmosphere vent hole and the liquid suction hole of the upper and lower end pipe plugs between the two pipes; a container mouth sealing cap having an insertion hole for the rising pipe and fixing the liquid rising pipe upright to the container mouth so that the lower end pipe stopper is located at the bottom of the container; An air expansion/contraction thermometer for teaching materials, comprising a temperature scale plate having a see-through part and fixed to the front side of the upwardly extending part of the container mouth of a liquid riser tube.

(2) The air for teaching materials according to claim 1 of the utility model registration claim, characterized in that the upper end pipe plug of the liquid riser pipe has a tank portion for receiving colored liquid overflowing from the end of the pipe. Expansion/contraction thermometer.

(3) The educational material according to claim 1 of the utility model registration claim, characterized in that the transparent part of the temperature scale plate is formed of a plastic-molded kamaboko lens which is bulged in a semi-cylindrical shape at intervals between scale lines. Air expansion and contraction type thermometer.
