When you take apart a pump for lotion, many people notice a small, unassuming notch at the end of the straw. The first thought might be, “Is this a production defect?” or “Will it affect liquid suction?” In reality, it’s the exact opposite—this seemingly unnecessary notch is an “optimized detail” specifically designed to address suction pain points, and it hides 3 super practical functions, carefully crafted by lotion pump factory designers.

Lotion pumps are common packaging accessories for liquid products such as skincare items, personal care products, and cosmetics. Thanks to their unique design and user experience, they are widely used in the consumer market and industrial production—this has also given rise to a large number of professional lotion pump suppliers, lotion dispenser pump manufacturers, and plastic lotion pump manufacturers.
