Perfume is very common in our daily life and favored by many beauty-loving women. However, perfume bottles sometimes leak during use. Do you know what causes this? Let’s take a look at the reasons for perfume bottle leakage below.

Perfume bottle leakage can stem from multiple factors. One cause is an uneven bottle mouth of the glass bottle. This usually happens when glass manufacturers produce bottles with defects or out-of-round mouths. Such glass bottles cannot form an airtight seal after the cap is tightened, which leads to perfume leakage.

A second cause of leakage is hidden cold cracks on the bottle mouth. These defects can only be spotted when holding the bottle mouth against light. Bottles with such cracks are defective products. No abnormalities can be detected right after filling perfume and vacuum pumping, but after a period of time, the cap will pop up, indicating the vacuum inside the bottle has failed, resulting in perfume leakage.

Another leakage issue arises from faulty caps. Most perfume bottle caps are made of iron sheet, yet many manufacturers opt for thin iron sheets to cut costs. Thin iron caps are prone to thread slipping or incomplete tightening, which also causes leakage during use.

The above are the main causes of perfume bottle leakage, which you should now have a clear understanding of.
