Flip-top caps are designed to provide convenient dispensing while maintaining secure product closure. They are generally manufactured using precision injection moulding, where molten polymer is injected into a mould containing the cap body, dispensing opening, hinge, and other functional features. After moulding, the components are inspected for dimensional accuracy, smooth operation, sealing performance, and compatibility with the intended bottle neck. Flip-top closures are particularly suitable for products that require frequent opening and closing, including: Shampoo Conditioner Body wash Liquid soap Lotion Personal-care products Pharmaceutical liquids Household liquids The hinged design allows consumers to open and close the package easily while keeping the dispensing opening protected between uses.
