How to check the sealing of the nail polish remover bottle?

1、 Air pressure testing method
preparation
Prepare a pressure gauge that can accurately control and measure air pressure. At the same time, prepare the nail polish remover bottle to be tested, ensuring that the surface of the bottle is clean and undamaged.
Determine the appropriate testing pressure range based on the specifications and materials of the nail polish remover oil bottle. Generally speaking, one can refer to similar product testing standards or consult professionals.
Testing process
Seal the nail polish remover bottle properly, usually by tightening the cap or using other sealing methods. Then, connect the bottle to the air pressure detector to ensure a tight connection and no air leakage.
Start the air pressure detector and gradually increase the air pressure to the set detection pressure. Observe the changes in the bottle under pressure and check for any bubbles, deformations, or other abnormal conditions.
Maintain the testing pressure for a period of time, usually ranging from a few minutes to several tens of minutes, depending on product requirements and testing standards. Continuously observe the sealing of the bottle while maintaining pressure.
Result judgment
If no bubbles, deformations or other abnormal situations are found during the detection process, and the pressure value remains stable after maintaining the pressure for a period of time, it can be considered that the sealing of the nail polish remover bottle is good.
If bubbles are found to emerge, deform, or the pressure value drops significantly, it indicates that the bottle has a leakage problem and the sealing is not qualified. Further inspection of the sealing parts of the bottle, such as the cap, mouth, and body, is needed to identify the cause of the leak and make improvements.
2、 Immersion testing method
preparation
Prepare a sufficiently large container that can hold the nail polish remover bottle to be tested and fill it with water. Ensure the cleanliness of the water and avoid impurities in the water affecting the test results.
Seal the nail polish remover bottle and ensure that the surface of the bottle is clean and undamaged.
Testing process
Fully immerse the sealed nail polish remover bottle in water, ensuring that all parts of the bottle are covered with water. Observe whether there are any bubbles coming out of the bottle in the water.
You can gently squeeze the bottle to simulate the pressure it may experience during transportation or use, and further check the sealing of the bottle. If bubbles are found to emerge during the squeezing process, it indicates that there is a leakage problem with the bottle.
Result judgment
If no bubbles are found during the entire inspection process, it can be considered that the sealing of the nail polish remover bottle is good.
If bubbles are found to emerge, it indicates that the bottle has a leakage problem and the sealing is not qualified. It is necessary to remove the bottle from the water, wipe off the surface moisture, further inspect the leaking area, and make improvements.
3、 Staining test method
preparation
Prepare a liquid that is easy to dye, such as a mixed solution of food coloring and water. This liquid should have good fluidity and staining properties, and be able to easily penetrate to the leakage site. At the same time, prepare the nail polish remover bottle to be tested, ensuring that the surface of the bottle is clean and undamaged.
Testing process
Pour the easily stained liquid into the nail polish remover bottle to a certain liquid level. Then, seal the bottle tightly to ensure a tight seal.
Place the sealed bottle in an observation area and wait for a period of time to allow the liquid to penetrate into the area where leakage may occur.
Observe the outer surface of the bottle and check for any dye liquid leakage. Magnifying glasses or other auxiliary tools can be used to observe small leakage areas more clearly.
Result judgment
If no staining liquid leakage is found during the observation process, it can be considered that the sealing of the nail polish remover bottle is good.
If dye liquid is found to be leaking out, it indicates that the bottle has a leakage problem and the sealing is not qualified. Further inspection is needed to identify the leaking area and make improvements.
