Innovative Design of the Pump Dispensers for the Bottle with Viscous Liquid

. The pressing pump head bottle of body wash, shampoo and liquid soap we use now that has some problems, that is the body wash or shampoo is used until only a little liquid is left, the liquid in the bottle cannot be pressed out by us, and liquid usually sticks to the body and mouth of the bottle. Based on these problems, this project collected the user feedback of existing products and made experiments on the existing products. Then improved the pump head and did experiments, and compared the experiments on existing products with the experiments on new design. In this design, in order to increase the utili-zation rate of liquid and improve the user satisfaction, this design changed the internal structure of the original pump head and added the shrink tube and rubber pad, so that the remaining liquid in the bottle can be pressed out, and the liquid outlet has also been changed. This project can help people reduce waste, and can be applied to various bottles for storing liquid. And this product will adopt the environment friendly material—Wheat Fiber Plastic, to achieve the purpose of environmental protection.
