A bottle is a narrow-necked container made of an impermeable material that stores and transports liquids. They are commonly shaped in many ways and can be sealed with an internal stopper, an external bottle cap or a closure.
Historically, bottles were manufactured from clay or other materials; however, the advent of glass manufacture has revolutionized the way we store and transport liquids. It is an ideal material for storing and transporting liquids because it is impermeable to air, water and other substances.
Bottles are used in all sorts of applications and are available in a wide variety of colors, shapes and sizes. They can be made from a variety of different types of materials, including glass, plastic and metal.
The most common type of bottle is a polyethylene terephthalate (PET) bottle. This material is inexpensive and can be produced to be highly resistant to moisture. PET is also commonly used in the production of pipes and lumber.
Some bottles, especially those for wine and spirits, are often a combination of materials. They may contain metal, glass or even wood.
They may be round or oblong. They are sometimes engraved or decorated with embossing, patterns and/or designs.
The most important part of any bottle is the base, which contains a large portion of the overall volume of the bottle. The base is generally the lowest portion of the body, and it terminates at the “resting point” – that point where the vertical tangency of the bottle’s body and neck intersect.
Another important part of a bottle is the shoulder, which lies between the resting point of the base and the base of the neck. Like the heel, the shoulder is a transition zone between two major portions of the bottle.
Lastly, the top of any bottle is called the rim. The rim is the extreme upper portion of the finish, where the bore or throat begins. Some people call the rim of a bottle the lip or ring, but these terms are not exactly correct.
When deciding which type of bottle to use for your project, it is important to keep in mind how the materials will be processed and what kinds of applications the bottle will be used for. It is also important to consider the resin that will be used for the bottle.
