Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1-2, a twist-off extraction tube comprising: a tube body 1 and a screw head 2. The tube body 1 is made of soft materials (such as rubber), is a soft hollow tube, can store extracting solution or other liquid inside, the tube body 1 can be pressed, liquid can be taken out by pressing the tube body 1, one end of the tube body 1 is sealed, one end of the sealed tube body is a liquid outlet 11, the other end of the sealed tube body is open, and one end of the open tube body is a liquid inlet 12; the screw head 2 is detachably connected with one end of the liquid outlet 11.
