38 400 vippelokk

The 38 400 flip top cap might look like a tiny detail, but it’s one of the most practical closure systems you’ll ever encounter. Whether you’re in cosmetics, food packaging, personal care, or industrial applications—this cap holds everything together. Its popularity among flip top plastic bottle caps isn’t just random. It comes from precision, purpose, and a well-thought-out design.

Product Details:

A 38 400 vippelokk is a closure with a diameter of 38mm and thread pitch compatible with 400 series bottles. That means it fits tightly, without leaks or fuss. The cap flips open smoothly—ideal for one-hand dispensing. This size often appears in industries demanding reliable flow control and user convenience.

Compared to twist-off or snap caps, the 38-400 flip top offers faster access and easier resealing. That’s why it’s a favorite among brands offering viscous products like ketchup, shampoo, or even sports gels.

What’s the Size and Why Does It Matter?

The “38” refers to the outer diameter in millimeters. The “400” indicates the thread style and depth. Together, 38mm plastic bottle caps with 400 thread finish ensure compatibility with standard neck bottles, especially PET or HDPE containers.

Why does this matter? Because packaging lines must run smoothly. Using 38 400 flaskekorker means fewer production issues, and swapping suppliers becomes less risky.

How to Make a Flip Top Cap: A Quick Glimpse into the Process

Manufacturing a 38 400 vippelokk starts with a carefully crafted mold—often steel or aluminum. The cap’s structure needs a flip top cap mould design that supports the hinge mechanism without breaking over thousands of uses.

Here’s the typical process:

Designing the Mold: Engineers develop a flip top cap mould using CAD software. Valve slots or logos can be included here.
Injection Molding: Polypropylene gets heated and injected into the mold.
Cooling & Ejection: The cap cools, then ejects with precision.
Assembly: If silicone valves or liners are needed, they’re added post-mold.
QC Check: Caps undergo leak and fit testing before packaging.

Working with an expert flip top cap manufacturer means fewer defects, faster production cycles, and better consistency across lots.
