38/400 Shampoo Flip Top Cap for Inverted Bottles | Double-Layer Dispensing Closure

Our 38/400 shampoo flip top cap is a large-size dispensing closure developed for shampoo bottles and other hair care packaging. The cap features a practical flip-top structure that allows consumers to open and close the bottle conveniently during daily use.

The specially designed double-layer inner structure helps improve the overall sealing and dispensing performance of the closure. Combined with its stable structural design, the cap is suitable for squeeze bottles and can also be used with inverted shampoo packaging, allowing the formula to remain closer to the dispensing opening.

Designed for repeated opening, closing, squeezing and daily bathroom use, this shampoo bottle cap provides a convenient and consumer-friendly packaging solution for shampoo brands, contract manufacturers and personal care packaging suppliers.

What Is a Flip Bottle Cap?   

A flip top cap is a plastic dispensing closure designed to provide convenient access to shampoo and other hair care formulations.

Unlike a conventional screw cap that must be completely removed before use, a flip top closure remains attached to the bottle. Consumers simply lift the top cover, dispense the desired amount of shampoo and close the cap again after use. Our 38/400 shampoo bottle cap features a large flip-top design and a double-layer internal structure. The design is intended to provide a stable closure structure while supporting convenient squeeze dispensing.

For shampoo bottles designed to stand upside down, the cap can function as the supporting base of the package. This configuration helps keep the shampoo closer to the dispensing opening and improves convenience when the bottle is nearly empty. The closure can be manufactured in different colors and customized to coordinate with bottle appearance, brand positioning and packaging requirements.

This design delivers:

• Clean and controlled dispensing

• No dripping after use

• Leak-proof sealing performance

• Hygienic dispensing experience

• Smooth flow for thick hair conditioner formulas

Compared with traditional flip-top caps, Hopewell flip bottle caps with valve provide a cleaner, more premium, and user-friendly dispensing solution for modern hair care packaging.

Key Features of the 38/400 Shampoo Flip Top Cap

1. Large Flip-Top Design

The large flip-top structure provides a convenient opening and closing experience.

Consumers can easily open the cap, dispense shampoo and close it again after use. The connected cap design also reduces the possibility of losing the closure during use.

2. Designed for Shampoo Dispensing

The closure is developed for squeeze dispensing applications commonly used in shampoo packaging.

When matched with an appropriate bottle and product formulation, it provides a practical dispensing experience for everyday hair care products.

3. Double-Layer Inner Structure

The internal double-layer design enhances the structural configuration of the cap.

This design can support improved sealing performance and provide a more refined construction compared with a basic single-layer dispensing closure.

4. Suitable for Inverted Bottles

The large cap design allows the package to be used in an inverted position.

For shampoo brands using stand-on-cap packaging, this helps keep the product near the outlet and improves convenience during daily use.

5. Durable for Repeated Use

The flip top is designed for repeated opening and closing.

Suitable for products that are used frequently in bathrooms, homes, salons and other personal care environments.

6. Customizable Appearance

Different customization options may be available according to project requirements, including:

Custom colors

Surface finish

Logo customization

Matching bottle designs
