Plastic lotion pump should not be used too often

The use of cosmetic plastic pump head should not be too frequent, because the spring spring resilience is limited, each use must be within the spring elastic range, not strong use, this is the same as the human limit, when a person’s physical strength is overdrawn, it will collapse. On average, each pump head should not be pressed more than 10 times, and the interval should not be less than 10 seconds. Allow enough time for it to bounce back. Cosmetics pump head built-in spring is not too long, of course, too short is not good, the general wire diameter selection and determination also plays a key role, in general, ordinary cosmetic pump head spring is 13 and a half turns of the most reasonable, so that the resilience and pressing pressure are just within a reasonable range.
