Common Types of Container Caps and Their Uses

One of the most popular type of container caps are screw caps, often seen on water bottles.

After filling your liquid products in the best containers, it’s time to apply the best cap. There are many bottle caps out there you can use to provide the security and appearance you desire for your product. How can you determine which container caps are best? Consider the following types most commonly used and the features each can bring to your product. At Filamatic, we can provide you with the complete liquid filling system you require, including capping machines that precisely cap every container to ensure consistent security and a beautiful final appearance for your containers.

Standard Screw Caps

Standard screw caps are most often used, although variations within this type of container cap exist. These caps allow users to unscrew and pour out the liquid before screwing them on tight again. These are often made from plastic or aluminum and placed on soft drinks, jars of honey, and even small medical vials, among many other products.

Some screw caps will include a tamper-proof seal around the neck that breaks with the first twist. There may also be a foil or plastic seal stretched across the open neck of the bottle or container to prevent leakage and tampering.

Flip Top Caps

Another screw cap variant is the flip-top lid. This cap is often used for squeezable containers stored with the cap down. You will see these caps on toothpaste, shampoos, and sauces. These caps may also include an inner foil or plastic seal.

Disc Top/Press Top Cap

The disc cap is similar to the flip top, but the user depresses the disc on one side of the cap while the other side pops upwards to release the product. Disc top caps are common choices for shampoos, face creams, sun creams, and other personal care products.

Sports Caps

Container caps often seen on sports drinks or water bottles are sports caps or a screw top variation that incorporates a shaped nozzle pointing upwards that you can pull to open and release the product. This cap must include a plastic protective cap to cover the nozzle.

Spray Caps for Beauty Products

Spray caps, heads, or atomizers are often added to perfume bottles or other personal care sprays. The cap is pressed down with one finger to release a fine spray of the liquid product. Most caps will be plastic, and to prevent accidental discharge, they often come with a separate protective cap over the nozzle.

Alcoholic Beverage Caps

Beer bottle or “crown” caps are metal caps that fit over the bottle before the capping machine crimps them into place. These container caps are a cheap and easy way to keep alcoholic beverages carbonated and free from leakage or tampering.

ROPP or roll-on pilfer-proof caps are used for products that must avoid tampering, such as alcohol. These caps also provide an airtight seal for sparkling wines. These caps are aluminum caps underneath a tamper-proof seal around the lid and neck of the bottle.
