What is a Disc Top Cover?
A disc top cap (also known as press-top cap or flip-top cap) is a functional dispensing closure widely used in personal care and household cleaning packaging. It features a two-piece structure with an integrated flat disc and a central pivot axis.
Working Principle: Press down on one side of the disc, and the other side will lift up to reveal the dispensing orifice.Function: Allows one-handed dispensing of liquids and semi-liquids, commonly used for shampoo, body wash, lotion and other packaging.
A variety of disc top caps in custom colors and aluminum finishes (gold, silver) are displayed, together with flip-top caps, push-pull caps and other plastic dispensing closures.
1. Structural Design & Working Principle
The disc top cap is valued for its simple structure and reliable performance.
- Lever Principle: The cap consists of a fixed base and a movable disc, which pivots on a central axis. Pressing the actuator lifts the disc like a seesaw to expose the dispensing hole.
- Self-Sealing Function: Press the raised end back to reset, which fits tightly with the cap body and automatically seals the orifice.
2. Core Product Advantages
① Ergonomic Design & One-Hand Operation
Suitable for high-frequency use in bathrooms, kitchens and other scenarios. Easy to open and close even with wet or slippery hands, without twisting or removing the cap, making operation safer and more convenient.
② Precise Dispensing & Controlled Dosage
The orifice size can be adjusted for products from low to medium-high viscosity. It prevents splashing and over-dispensing for both thin toners and thick conditioners, reducing product waste.
③ Leak-Proof Sealing & Safe Transportation
In the closed position, the disc seals tightly with the orifice. Most models are equipped with inner sealing rings and reinforcing ribs to pass leakage tests, meeting requirements for e commerce logistics and international transportation.
