2. Set the anti-opening component, insert the anti-opening component into the outer casing or the indenter so as to be in contact with the indenter, so that the indenter is fixed to the outer casing to achieve the function of the indenter limit, thereby preventing the indentation from being inadvertently pressed. Causes fluid to flow out of the bottle.

3. By setting the stopper and the bump on the braces and the bottle neck respectively, the position of the stopper corresponds to the position of the bump. When the braces are screwed to a certain extent on the bottle neck, the bump of the bottle neck and the stopper of the braces are pressed against each other. The head can not continue to screw in, effectively solve the orientation problem of the liquid outlet, and increase the uniformity and aesthetics of the bottle.

4. Through the mutual cooperation of the support ring, the support platform and the notch, the dispenser is in a locked state or an open state, thereby locking or opening the indenter to prevent accidental touch during use.

5. Set the straw to bend toward the corner of the bottom of the bottle, and define the angle between the bending direction and the direction of the nozzle to be 0~45°, so that the creation can effectively remove the bottom of the bottle. The remaining liquid is sucked out, which solves the problem that the remaining liquid in the bottle cannot be taken out and is wasted, thereby improving the user experience.
