If you pay attention, you will find that although the shampoo bottle body has not changed much, the shampoo bottle cap is constantly changing and upgrading. The initial shampoo bottle cap was a common screw plastic cap, and then more and more shampoo bottle caps used butterfly caps. Indeed, the butterfly cap is more convenient when using squeezing shampoo. Now, all kinds of squeeze pump heads have become the latest way to adopt shampoo bottle caps. Compared with other bottle caps, the squeeze pump head is easier to control the volume and more convenient.

The development and change of shampoo bottle caps are constantly moving towards humanization. This is something that other packaging bottle caps in the bottle cap design process are worth learning. Many bottle cap designs are very traditional and do not change much and require continuous improvement.

However, the current squeezed shampoo bottle cap still has some defects and needs to be improved. Squeeze pumps are sometimes inconvenient to squeeze and need to be more reliable.
