No Residue Bottle
Product design | Structure design
It can make the liquid in the bottle be completely pressed out through the cooperation of the inner components of the bottle, so that there is no residue in the bottle.
When there is only a little liquid left in the bottle, it is hard to be pressed out, users usually
turn the bottle upside down and let the bottom liquid flow out along the bottle wall, or add water,
but it is inconvenient.

How it works and design process
When the pump head is pressed down by hand, the pressure in the bottle has been large, the spring is compressed, the glass ball valve is closed, the stem moves downward, the outlet hole on the stem is opened, The liquid in the pump body enters the inner pipe from the outlet hole, then flows out of the pipe, and finally reaches the bowl-shaped pump head. When the hand is loosened, the spring recovers, the pressure in the bottle decreases, the stem moves upward, the liquid outlet on the stem is closed, and the ball valve opens. Under the action of atmospheric prressure, the liquid enters the pump body from the dip tube through the ball valve, and shrinkable dip tube and rubber pad move up at the same time.
3D print & usage scenario
Experiment
Here is a bottle with a length, width and height of 5.5cm, 5.5cm and 13cm. I installed the 3D printed shrink tube and rubber pad in the bottle.In order to simulate the situation that when we use shampoo and other similar products
in life, a part of the liquid at the bottom of the bottle cannot be pressed out, I added about 47.5ml (2 centimeters) of shampoo.
Results
The liquid has buoyancy. In the course of doing the experiments, due to the buoyancy of liquid, shrink tube and rubber pad can’t cling to the bottom of bottle, it moved up by 1.5 centimeters. At this time, the remaining liquid on the rubber pad is about 12ml. When I pressed the pump head 7 times, the liquid on the rubber pad is pressed out, and the rubber pad also moved.
