The Three Main Parts of a Bottle


A bottle is a container with a wide mouth that is commonly used to store liquids. Bottles are typically made of glass or other impermeable materials. However, bottles can also be made of plastics. These containers are sealed with external or internal caps to prevent evaporation and leakage.

Bottles come in many shapes and sizes. They can be cylindrical or round, with or without a shoulder. Some bottles, like Champagne bottles, are more ornate than others. But no matter the shape, there are three main parts to a bottle: the body, the collar, and the neck. While the body is the fulcrum of the bottle, the collar and neck are the main components that are responsible for the container’s final appearance. The collar can be a ring or a skirt.

The neck is the constricted section of the bottle that sits above the rim. The top of the neck is often a parting line that is marked on the finished product to mark where the finish mates the body. This line is also known as a parting line or a seam.

The rim is the extreme uppermost surface of the finish. The rim may have a small recessed spot for labeling. It is also the location of a bore, or a circular opening.

The neck is the constricted part of the bottle that sits above the ring. The top of the neck is often manipulated during the finishing process of mouth-blown bottles. In the glass industry, the name ring is used to describe a ridge at the base of the finish.

One of the more confusing finish terms is the lip. This is a bit more complex than its cousins, and is usually described as a spiral-shaped ridge on the finish. This ridge is designed to mesh with a screw-type closure, if present. There is a debate over whether or not the upper neck actually qualifies as a finish in its own right.

The neck is the constricted portion of the bottle that sits above the rom. The top of the neck is often shaped like a parting line, and is sometimes called a parting line or a seam. As with the other parts of the bottle, the neck ring is used to mark the join between the finish and the bottle body.

One of the more intriguing finishes is the stippled finish. Stippled finish is a form of finishing in which abrasions are focused on high points of the bottle. When finished in a mold, the stippled effect reveals a semblance of perfection to the eye.

Another of the more interesting finish details is the embossing. This is a fancy trick performed on the inside of the mold to produce a raised graphic. Raised graphics are more effective at reducing odor and gas/vapor permeation through the walls of the container, as well as the release of chemicals from the product.

While the smallest bottle might be a misnomer, it is not unheard of. For example, the smallest bottle, measuring only about a centimeter in diameter, has a body that is about a meter in length.
