The plug 3 is a revolving body structure, the plug 3 is sleeved on the nozzle 204 to seal the nozzle 204, and the plug 3 can be relatively fixed and separated with the nozzle 204.

The first embodiment is described in detail as follows:

in the first embodiment, the tube body 2 is composed of a tube head 201, a tube body 202, a tube skirt 203, and a nozzle 204, and is an elongated rotary body as a whole. The tube head 201 is partially threaded for engagement with the internal threads of the closure 1, and the wall thickness of the tube head 201 is such that it is strong enough not to deform significantly during normal operation. The pipe body 202 is slender, and the pipe wall of pipe body 202 is thin, intensity is little, can take place elastic deformation when exerting finger force, makes things convenient for the inside cavity volume of body to change, eliminates external force after, the pipe body 202 is through self material elasticity self-recovery original shape. The tube skirt 203 is arranged at the lower end of the tube body 202, and the tube skirt 203 has a tube wall thickness which ensures proper strength, is not easy to deform, and can protect the nozzle 204 from contacting with other objects. One end of the nozzle 204 is communicated with the cavity in the tube body, the other end is communicated with the outside of the tube body, and the inside of the nozzle is provided with a pore which can discharge liquid when necessary. The protruding snap 205 is protrudingly provided on the nozzle 204 and evenly distributed in the circumferential direction.

In application, the tube body 2 can be used for applying external force to the tube body 202 with a thin tube wall, so that the tube body 202 can be inwards sunken, and the volume of the tube body 202 is reduced. When the body 202 is recessed from a thin wall to a thick wall, there is a noticeable tactile sensation due to the significant change in strength. The tube body 202 is less able to return to its original shape when the external force is removed from the thin tube wall. External force is applied to the thick pipe wall, so that the pipe body 202 can be recessed inwards, and the deformation degree of the pipe body 202 can be obviously increased. The external force on the thick tube wall is removed and the tube body 202 recovers its original shape.
