What Are Glass Bottle Cap Types

As an important sealing component of glass containers, glass bottle caps play a key role in many industries such as food, beverages, and medicine. There are many glass bottle cap types and each type has a unique design, function, and application scenario.

Screw cap: The screw cap is a very common type of glass bottle cap. It fits tightly with the glass bottle mouth through the thread to achieve a good sealing effect. The operation is simple and convenient, and it can be easily opened and closed by rotating. Due to its excellent sealing performance, it can effectively prevent liquid volatilization and external impurities from entering, and is widely used in beverages, condiments, medicines and other fields. Like common bottled beverages, small bottles of medicines, etc., many use screw cap design.

Press-screw cap: Press-screw cap combines the two modes of operation, pressing and rotating. When using, you need to press the bottle cap first and rotate it at the same time to open it. This design increases the difficulty of opening and can effectively prevent children from opening it by mistake. Therefore, it is more common in pharmaceutical packaging and provides a guarantee for the safe storage and use of medicines.

Crown cap: The crown cap is shaped like a crown and is usually used to seal beer, carbonated drinks and other beverages with a certain pressure. It is pressed tightly on the bottle mouth through a special sealing device, which can withstand the internal pressure generated by the beverage and ensure that the gas will not leak, thereby maintaining the bubbles and taste of the beverage. However, once the crown cap is opened, it is difficult to seal it again and it is a disposable bottle cap.

Cork cap: Cork cap can be further divided into cork and plastic cap. Cork has good elasticity and air permeability, which can allow wine and other alcoholic beverages to oxidize slowly in the bottle, promote the formation and development of flavor, and is often used in the packaging of high-end wine. Plastic cork has a lower cost and good sealing performance, and is used in some mid- and low-end alcoholic beverages and other liquid products.

Pilfer proof caps: The anti-theft cap is designed with an anti-theft ring or other anti-theft structure. When the bottle cap is opened for the first time, the anti-theft ring will break or show obvious signs of damage, which will inform consumers whether the product has been opened, ensuring the safety and quality of the product. It is often used in food, health care products and other products with high safety requirements.
