Content and compatibility requirements of cosmetic bottles

Use a measuring cylinder to measure a certain amount of water and fill it to the shoulder of the bottle to calculate whether the net content requirements are met. If necessary, use the actual content for testing. When the content is filled to the shoulder of the container (aesthetic filling height), it must be greater than the product label value and less than 105% of the product label value.

The bottle and the cap (sprinkler), gasket, and inner plug (inner bowl) must fit smoothly, without being too tight, too loose, crooked, or slipping; the distance between the bottle and the cap (sprinkler) is between 0.3-0.8mm.
