An aluminum disc top cap can be a very practical way to package a liquid product. These caps are commonly used in the health and beauty industries. They come in various sizes including 20, 24 and 28 mm.

Disc top caps are very convenient as they allow the user to dispense a product without unscrewing the cap. They have a recessed region on the top, which exposes a dispensing "orifice" when light pressure is applied.

The disc top cap is then closed by pressing down on the raised area of the cap. Disc top caps come in a variety of shapes and sizes and are easy to use. They are suitable for a variety of liquid and gel products. However, they are not recommended for very thin products.
