After the eye drops flow out of the dropper, a user loosens the button part, the button part rebounds to the original position along the guide groove due to the elastic action of the spring, and in the process, the button part rotates anticlockwise for an angle, and the spiral driving sleeve cannot rotate along with the anticlockwise rotation of the pawl part as long as appropriate friction force exists between the outer wall of the spiral driving sleeve and the inner wall of the outer bottle body due to the fact that the driving direction of the pawl part is clockwise. The upper limiting bulge of the adjusting knob is matched with the upper limiting convex ring of the outer bottle body, so that the adjusting knob cannot be separated from the outer bottle body after being installed on the outer bottle body; due to the limiting effect of the retainer ring on the adjusting knob, the button part can not be separated from the outer bottle body.
Because the inner container extrusion part and the spiral driving sleeve which are used for directly driving the silica gel inner container to be compressed are completely positioned in the outer bottle body, and only part of the button part used for pressing is positioned above the outer bottle body, the button part and the inner container extrusion part have smaller proportion compared with the silica gel inner container which is used for directly containing eye drops, so that the effective space utilization rate of the packaging bottle is obviously higher than that of the packaging bottle in the background technology.
