している。A medical worker who inspects the contents placed in a test tube, such as a blood test, attaches and detaches a large number of test tube caps every day. When removing the cap of the test tube, grasp the test tube with one hand and push up the side of the cap head with the belly of the thumb of the grasping hand to remove the cap from the test tube. There is.

る。Further, when the test tube is fitted with the cap, the test tube is grasped by one hand, the other hand is held by the cap, and the cap is fitted on the test tube, and then the belly of the fingertip of the thumb on the side where the test tube is grasped. Is holding the head of the cap. In this way, since the belly of the fingertips of the thumb is used both for fitting and removing the cap on the test tube, a large number of caps can be attached and detached, causing pain in the thumb and affecting work efficiency. is there.

々生じていたのである。Particularly, when the head is pressed by the belly of the fingertip of the thumb when the cap is fitted, the ring-shaped portion at the upper edge of the head hits strongly, and a ring-shaped mark remains on the belly of the fingertip of the thumb. is there. Also, when pressing the head with the belly of the fingertip of the thumb, if pressure is not applied vertically downward from a point on the center of the upper surface of the head, the cap will tilt and the inner plug of the cap will not be inserted smoothly and will not be pressed strongly. It often happened that it was difficult to fit.
【０００６】上記点より、本発明はキャップの嵌入が容
易な試験管用キャップを提供しようとするものである。From the above point of view, the present invention is intended to provide a test tube cap in which the cap can be easily fitted.

ことができる。According to the present invention, the upper surface of the head of the cap is formed into a bulged dome-shaped arc surface. Therefore, when fitting the cap into the test tube, pressing the upper surface of the head of the cap with the belly of the fingertip of the thumb, the pressure is directed toward the center because the upper surface is a dome-shaped arc surface with a bulge, and the inner plug is also weakly applied. It can be easily fitted into a test tube without tilting.

明である。According to the present invention, since the upper surface of the head of the cap is formed into a dome-shaped arc surface, when the cap is fitted into the test tube, the head of the cap is held by the belly of the fingertip of the thumb. If you press the dome-shaped circular surface, the pressure will be directed to the center, so you can fit it with a weak force, so even if you put on a large number of test tube caps every day as work, you will not feel pain in your thumb, and work It is a useful invention that can significantly improve the efficiency.
