FIG. 3 is a diagram showing an embodiment of the test tube stopper of the present invention. FIG. 1 is a perspective view of the rubber stopper cut vertically along the broken line 1 in FIG. FIG. 2 is a sectional view taken vertically along the broken line 1 in FIG. 3 when the rubber stopper is placed over the test tube 6. FIG. 3 is a plan view seen from above. FIG. 4 is a cross-sectional view of only the rubber stopper taken along the broken line 1 in FIG. 3. FIG. 5 is a bottom view when viewed from below. 2 is a protrusion that functions as a valve. 3 is a cover stopper. 4 is the middle stopper. 5 is a cover plug air intake that has a notch in the cover plug to guide air to the valve part. 6
is a test tube. 7 is a test tube stopper to prevent the test tube from slipping.

試験管のゴム栓。 A stopper is a stopper with a part of the inside of the stopper that makes contact with the head of the test tube carved out, and a protrusion that comes in contact with the test tube and acts as a valve. When the internal pressure of the test tube decreases, the protrusion that acts as a valve separates from the test tube, allowing outside air to enter the test tube's rubber stopper.
