Disc top caps are dispensing closures designed to open and close by pressing one side of the top surface, exposing an orifice for controlled product dispensing. Also referred to as disc top closures or press-top caps, they are commonly paired with plastic bottles for shampoos, conditioners, lotions, body washes, cleansers, household products, and other liquid or semi-viscous formulas. Closure selection depends on the bottle neck finish, formula viscosity, desired flow rate, orifice size, sealing requirements, and intended use.

Disc Top Cap Options:

20-410 Disc Top Caps: 20-410 disc top closures can be paired with bottles using a compatible 20-410 continuous-thread neck finish. Available orifice sizes, materials, colors, and liner configurations vary by manufacturer.
24-410 Disc Top Caps: 24-410 is a common neck finish for disc top dispensing closures used across personal care, beauty, and other liquid products. Bottle and closure specifications should be matched before production.
28-410 Disc Top Caps: 28-410 disc top closures provide another option for bottles requiring a larger neck finish. Available designs and dispensing orifices vary by closure family and manufacturer.
Orifice & Dispensing Options: Disc top caps are available with different dispensing orifice sizes and closure designs. The appropriate configuration depends on formula viscosity, desired flow rate, bottle design, and how the consumer will dispense the product.

How Disc Top Caps Work:

A disc top closure uses a hinged or pivoting disc within the top of the cap. Pressing one side of the disc raises the opposite side and exposes the dispensing opening. Pressing the raised side returns the disc to its closed position. This allows the package to be opened and dispensed without removing the closure from the bottle.

Disc Top Cap Materials:

Disc top caps are commonly manufactured from polypropylene and are available in a range of colors, finishes, and configurations. Available specifications vary by manufacturer. Material selection should account for the intended formula, dispensing requirements, filling process, storage conditions, and other package requirements.

Choosing a Disc Top Closure:

Start by matching the closure to the bottle neck finish, such as 20-410, 24-410, or 28-410. Then consider the formula viscosity, dispensing orifice, desired flow rate, closure dimensions, liner or sealing system, bottle geometry, filling process, and chemical compatibility. A matching neck-finish designation alone does not establish that a bottle and closure will perform correctly together.

Compare disc top caps and press-top closures by neck finish, orifice size, material, color, minimum order quantity, and manufacturing location. Request quotes, samples, or technical documents from packaging manufacturers and suppliers. Products shown in this category may be suitable for one or more applications, but category placement does not guarantee compatibility with a specific product or filling process. Closure fit, seal integrity, dispensing performance, and chemical compatibility should be confirmed with the manufacturer and validated with the intended bottle and formula before production.

FAQs

What is a disc top cap?

A disc top cap is a dispensing closure that opens when one side of the top disc is pressed, causing the opposite side to rise and expose a dispensing orifice. The closure can be opened and closed without being removed from the bottle.

What are disc top caps used for?

Disc top caps are used for shampoos, conditioners, lotions, body washes, cleansers, household products, and other liquid or semi-viscous formulas. Suitability depends on the formula, bottle, closure specifications, and dispensing requirements.

What sizes do disc top caps come in?

Disc top caps are available in multiple neck finishes, including 20-410, 24-410, and 28-410. Other sizes and specifications may also be available depending on the manufacturer and closure family.

What is a 24-410 disc top cap?

A 24-410 disc top cap is designed for a compatible bottle with a 24-410 continuous-thread neck finish. The “24” identifies the nominal neck diameter in millimeters, while “410” identifies the thread style.

Are disc top caps the same as flip-top caps?

No. A disc top cap opens by pressing one side of a pivoting disc, while a flip-top closure uses a hinged lid that is lifted or flipped open. Both provide dispensing without requiring the entire closure to be removed.

How do I choose the right disc top cap?

Match the closure to the bottle neck finish and evaluate the formula viscosity, orifice size, desired flow rate, sealing system, bottle design, filling process, and chemical compatibility. Samples should be tested with the intended bottle and formula before production.
