Product Information
Flip top bottle caps, also known as flip-top caps, are dispensing closures designed for easy one-handed opening and closing. Hopewell offers a public mold flip top bottle cap featuring a silicone valve, specifically for a 38-400 neck finish size with a 40mm outer diameter.
The 38-400 flip top bottle cap is a premium dispensing closure solution combining a traditional flip-top design with an innovative silicone valve sealing system. Unlike conventional bottle caps, this flip top cap with silicone valve provides a better user experience by controlling liquid flow and preventing unwanted leakage. When the bottle is squeezed, the cross slit silicone valve opens smoothly to release the product. Once pressure is released, the valve immediately closes to maintain a clean and sealed dispensing environment.
The integrated silicone check valve creates a reliable sealing structure, preventing liquid leakage when the bottle is stored upside down or transported.
The silicone valve provides consistent flow control, allowing users to dispense the right amount of product without excessive pouring or splashing.
The self-closing valve minimizes dripping after dispensing, keeping bottle openings clean and reducing product waste.
The sealed valve design helps prevent dust, bacteria, and external contaminants from entering the bottle, extending product freshness.
The cap is made from food-grade PP and silicone materials suitable for food contact applications. Materials can meet FDA and EU food contact requirements according to customer needs.
Hopewell provides OEM customization options including:
Custom cap colors
Customized valve opening force
Different silicone valve slit designs
Logo customization
Packaging customization
How to Use

What’s optical silicone?
Optical silicone is a bi-component ultra-transparent liquid silicone rubber material, with very good optical properties and flame resistance. Under long-term harsh environment, for example, under high temperature or UV radiation, the color keeps stable and the optical clarity maintains. In addition, the excellent processing properties enable it to be manufactured to tight tolerance complex or micro-structure optical parts, which brings new possibilities for cutting-edge technology in LED high-powered automotive lighting and electronics.
108
What’s the difference of properties between optical liquid silicone and other materials?
