Shampoo pump head is a common shampoo bottle cap that is usually used for pouring out liquids such as shampoo. After using the shampoo, the pump head needs to be screwed back to avoid shampoo waste and prevent air from entering the bottle. Here's how to tighten the shampoo pumphead.
First, tilt the shampoo pump head down so that the remaining shampoo can flow smoothly back into the bottle. This step is very important because if the pump head is not fully closed, the shampoo may drip or spray out, causing unnecessary trouble.
Next, rotate the pump head upwards until you hear a "click" indicating that the pump head is fully closed. This step requires attention and angle to ensure that the pump head can return to its original position accurately.
If you find that the pump head cannot be fully screwed back, it may be because the air pressure inside the bottle is too high or the residual shampoo is preventing the pump head from returning. At this point, the following measures can be taken:
1.Wait for some time for the air inside the bottle to cool down, as the air pressure may become higher at high temperatures.
2.Wipe the pump head and bottle mouth with a clean towel or paper towel, making sure there is no residual shampoo or impurities blocking the return of the pump head.
3.If the above methods still don't solve the problem, you can try gently tapping the pump head or bottle to let the remaining shampoo or air out, and then try tightening the pump head again.
Finally, if you find that the pump head has been damaged or is not working properly, it is recommended to replace it with a new pump head or bottle in time. Shampoos or pumps of the same brand and model as the original can be purchased in supermarkets or pharmacies to ensure compatibility and reliability.
In conclusion, tightening the shampoo pump head requires attention and angle to ensure that the pump head returns to its original position accurately. If you encounter a problem, you can take corresponding measures to solve it. At the same time, it is recommended to regularly inspect and maintain the shampoo pump head to ensure its normal operation and service life.
