23 Types of Container Caps and Their Uses

Packaging bottles have different containers designs and caps. All these caps have their own uniqueness in terms of features, functionality and safety.

This article discusses the different types of container caps in detail. Read on.

Types of Container Caps

1. Screw Caps

Screw caps use a unique closing mechanism, where caps that screw onto container threads generate a secure seal. These caps are very common. The threads in containers are made to match those within the cap. Therefore, they tighten when they meet the mouths of containers.

You will find them in aluminum, plastic, or silicone rubber. These caps are ideal for different containers with beverages like soda, water, sauces, and more.

3. ROPP Cap

Also known as roll-on pilfer-proof caps, these caps are made of metal and are used to seal containers or bottles. A special capping device is used to roll caps onto the thread of bottles. They come with a design that is tamper-clear.

This makes it hard for ROPP cap bottles to be opened without the cap getting damaged. This provides consumers with some level of assurance and safety when using containers with these caps.

4. Press and Seal Caps

A press-and-seal cap ideally comes with materials that are flexible and match the rim of the container. Therefore, when the cap is pressed to the container rim, it seals the contents perfectly. These caps are pressed onto the opening of containers for a secure seal to be created.

Press and seal caps are used mostly for containers like bottles, jars, and others.

10. Pump Caps

A pump cap comes with a nozzle connected to a piston within a cylinder. When the pump head is pressed, pressure is created within the cylinder. This causes piston movement, which draws fluid up through tubes linked to the cylinder.

You will find them used on containers with products such as shampoos, lotions, and soaps. This cap truly controls use of product and reduces waste.

Corks are very common stoppers that have always been used to seal wine and spirit bottles. They are made from cork oak tree barks, then pushed into bottle necks to keep bottle contents safe. Corks make it possible for some minute air to enter wine. This helps wine develop flavor and age, which makes them perfect for wine bottle sealing.

20. Twist Top

A twist top cap is a cap that comes with a threaded liner within. This liner screws into bottle necks, leading to tight seal created. When the cap is twisted clockwise, it tightens connecting to bottle neck threads to seal contents within.

On the other hand, it loosens when the cap is twisted anticlockwise. Most liquid and dry products on the market use these caps for packaging.
