Bottle caps come in many shapes and sizes, and each type has its own purpose. Some are designed for use with specific bottles, while others are meant for general use. The Standard Bottle Cap.

These lids are often used on bottles containing liquids such as milk, juice, water, soda, beer, wine, etc. The screw top has been around since the early 1900s, and it’s still one of the most common types of closures today. In fact, there are many different kinds of screw tops, including those that use a cork, rubber gasket, metal ring, plastic ring, and others. Some screw tops are designed to be reusable while others are meant to be thrown away after opening once. The Twist Off Cap. There are two main types of bottle caps: twist off and pull tab. Both types of caps come in various sizes and shapes. Bottle caps are used to seal bottles, jars, and other containers.
