A bottle is a narrow-necked container of glass or plastic in a wide variety of shapes and sizes used for holding liquids. Often the bottle has a wider base and a cap or closure to prevent leakage or evaporation. The bottle is typically sealed using either an internal stopper or an external bottle cap, and can be further tamper-proofed by use of a cork or a sealant such as induction sealing. The judi bola term “bottle” also can be applied to a container of any type that holds and transports liquids, such as a flask, jug or canteen.
The bottle is one of the most common and familiar containers in human history, and has been used for both utilitarian and decorative purposes. Bottles can be made from a number of materials, including glass, plastic, metal and various combinations thereof, and can have a wide range of uses. Bottles may be manufactured through a variety of processes, most commonly through blow molding.
There are a number of terms that are used to describe the different parts of bottles, and the terminology can vary from source to source. This glossary is intended to provide a common language and set of definitions for these terms, and is frequently linked back to throughout this site to clarify the terminology being used.
Collar – The extreme upper surface of the finish where it meets the neck. It is sometimes called the lip by some, and is a more specific term than the rim which is generally considered to be the entire upper portion of the finish.
Heel – The lower part of the body (sidewall) where it turns from vertical to horizontal and joins the base. The heel can be provided with a recessed spot that serves as a registration device for labeling and decorating equipment, and may have a raised pattern to mask scratches from handling.
Shoulder – The transition point between the wide main body and the narrower neck, where the slope of the shoulder helps to determine how quickly a product is dispensed when the bottle is inverted. The shoulder can also be provided with a recessed label panel for application of labels.
Body – The wide and central area of the body, which is usually given a stippled finish in the mold to mask scratches from handling and to prevent them from concentrating at stronger points, thus weakening the bottle. The bottom of the bottle is supported by an even bearing surface known as the pushup or kickup, which is provided with a ring around its outside edge and often with a stippled pattern to help mask scratches that could cause the bottle to weaken or break.
The production of a single plastic bottle requires large amounts of energy and raw material, which is derived primarily from crude oil obtained through extraction methods such as drilling or fracking. The crude oil is then refined into polyethylene terephthalate (PET), which is the primary material used to make plastic bottles. PET is a strong, lightweight, and chemically resistant plastic used by many food and beverage producers for their products, as well as other household and commercial goods.
