6 Common Types of Plastic Bottles Caps Manufactured by Shuanghao Mould
In the fast-paced world of packaging, the humble plastic bottle cap plays a critical role in product integrity, user convenience, and brand identity. As a leading plastic cap mould manufacturer, Shuanghao Mould specializes in designing and producing high-precision injection moulds for bottle caps for various industries.
Choosing the right cap is essential for functionality and consumer appeal. Here are the 6 most common types of plastic bottle caps we expertly craft moulds for.
1. Screw-On Caps
The most ubiquitous type of cap, screw-on closures are the standard for water bottles, soda, and many beverage containers.
Functionality: They feature continuous threads on the inner wall that screw onto corresponding threads on the bottle neck, creating a secure, reusable seal.
Common Uses: Water bottles, soft drinks, juices, and household chemicals.
Shuanghao Mould's Expertise: We engineer durable screw cap moulds with precise threading to ensure a perfect seal and smooth application every time.
2. Dispensing Caps (Flip-Top & Sport Caps)
Designed for on-the-go convenience, dispensing caps allow controlled release of the product without fully removing the cap.
Functionality: These often feature a hinged top that flips open and snaps shut. Sport caps have a pull-tab spout, ideal for drinking while active.
Common Uses: Sports drinks, condiments (ketchup, mustard), lotions, and body wash.
Shuanghao Mould's Expertise: Our complex plastic cap moulds for dispensing caps incorporate intricate hinge mechanisms and sealing surfaces for leak-proof performance and longevity.
3. Child-Resistant (CR) Caps
Safety is paramount for household chemicals and pharmaceuticals. Child-resistant caps require a specific, simultaneous action to open, making them difficult for children to access.
Functionality: Common mechanisms include "push-down-and-turn" or aligning arrows and applying pressure.
Common Uses: Prescription medications, cleaning products, and certain automotive fluids.
Shuanghao Mould's Expertise: We design injection moulds for bottle caps that meet stringent CR safety standards, ensuring they are both challenging for children to open and accessible for adults.
4. Sprayer Caps
Essential for misting or spraying liquids, these caps integrate a pump mechanism directly into the closure.
Functionality: A built-in pump draws liquid from the bottle and dispenses it as a fine mist or stream when the trigger or actuator is pressed.
Common Uses: Cleaning sprays, garden products, cosmetics (hairspray, setting spray), and disinfectants.
Shuanghao Mould's Expertise: Shuanghao Mould produces high-tolerance moulds for the complex housing that holds the pump mechanism securely and ensures a proper seal with the bottle.
5. Tamper-Evident Caps
These caps provide visible proof that a product has been opened or tampered with, offering consumers peace of mind.
Functionality: They typically have a ring or band that breaks away from the main cap upon the first opening. This band remains on the bottle neck, indicating the seal has been broken.
Common Uses: Dairy products, medicines, juices, and premium food items.
Shuanghao Mould's Expertise: Our plastic cap moulds are precision-engineered to create a clean, reliable breakaway ring that functions flawlessly on high-speed capping lines.
6. Overcaps
Overcaps are secondary caps placed over a functional closure, primarily for aesthetic and branding purposes.
Functionality: They do not form a seal with the bottle but are designed to cover a pump, sprayer, or dropper to create a sleek, uniform look and prevent accidental dispensing.
Common Uses: Luxury cosmetics, skincare products, and high-end cleaning supplies.
Shuanghao Mould's Expertise: We create visually perfect custom plastic cap moulds for overcaps that enhance brand perception with a superior finish and perfect fit.
