What aspects are included in the quality inspection standards for perfume bottle caps?

The quality inspection standards for perfume bottle caps encompass several critical aspects, including seal performance testing, physical dimensions and weight inspection, functionality testing, adherence to quality management system standards, and compliance testing. These comprehensive checks ensure the durability, reliability, and international compliance of the caps.

Seal Performance Testing: This is one of the most critical inspection items. Evidence suggests that seal performance testing typically involves capping the perfume bottle using a capping machine at the specified torque to meet capping requirements, followed by testing with a seal tester. The specific steps include pressurizing to 200 kPa, maintaining pressure underwater for 1 minute, and observing for leaks. Then, the pressure is increased to 350 kPa, held for 1 minute, and observed to see if the cap dislodges. The requirements are no leaks at 200 kPa and no cap dislodgement at 350 kPa.

Physical Dimensions and Weight Inspection: This includes checking the color, appearance, surface, connecting ring, interior, weight, height with and without rings, external diameter, cap dimensions, threaded and non-threaded internal diameters, height from cap opening to base, inner edge diameter, thickness with and without gasket, gasket dimensions (diameter and thickness), and aluminum foil printing.

Functionality Testing: This may include impact tests and drop tests to ensure the durability and reliability of the cap in actual use.

Quality Management System Standards: The production process strictly follows quality management system standards such as ISO9001 and SGS to control product quality, ensuring that the products meet international standards.

Compliance Testing: Ensuring that the caps comply with relevant technical regulations and standards, such as the TR CU 005 / 2011 packaging safety regulations.
