Everything You Need to Know About Bottle Flip Top Cap 38 400
A bottle flip top cap in the 38-400 size is more than just a closure. For brands in food, personal care, or industrial products, this cap offers controlled dispensing, strong sealing, and customer-friendly operation. Whether you need a high-flow cap for sauces or a spill-proof design for shampoos, this style delivers both performance and shelf appeal.
What Exactly Is a Bottle Flip Top Cap?
A bottle flip top cap—sometimes called a 38mm flip top cap or plastic bottle flip top cap—uses a hinged lid that snaps shut over a dispensing orifice. One quick flick opens the lid, allowing product flow without fully removing the cap.
The 38-400 refers to the neck finish: 38mm diameter, 400 thread style. This size suits large-mouth bottles, ideal for thicker liquids and granulated products.
Why Cap Size Matters for Bottle Flip Top Cap 38 400
Cap size affects more than fit—it shapes user experience.
Flow Control: Larger openings in 38mm caps let out thicker sauces, creams, or gels smoothly.
Ease of Use: A bigger cap top is easier to open for users with limited grip strength.
Compatibility: Matching the 38-400 thread ensures a leak-free seal on bottles with that neck finish.
Choose wrong, and you risk leakage, excess product waste, or poor customer satisfaction.
