What Is a Bottle?


A receptacle with a narrow neck and usually no handles, used to store and transport liquids. It can be plugged, corked, or capped. The mouth of a bottle can also be opened for use, as in feeding. A bottle may be made of glass or plastic.

The word can also refer to a container that holds intoxicating liquor, such as a flask or a whisky bottle. It can be filled and sealed, or it may hold inert gas, such as carbon dioxide, for pressurization.

A bottle can also be used to hold milk or formula that is fed, such as baby bottles for babies. It can also be used to hold a beverage, such as soda or beer. It can be carried in a pocket, on a belt or strap, or slung over one shoulder. The word is also sometimes used to refer to the quantity a bottle holds, or to the practice of drinking intoxicating liquor from it.

There are many ways to make a bottle, including blow molding, extrusion, and injection molding. The most popular material for making plastic bottles is high-density polyethylene (HDPE), a resin with the resin identification code 2. It has a good strength-to-weight ratio, is resistant to many solvents, and can be easily shaped and molded into a bottle shape. It is often coated with a layer of plasticizer to enhance its transparency and chemical resistance.

Plastic bottles are often made of various other plastics as well, such as polyvinyl chloride (PVC or vinyl), acrylonitrile butadiene styrene (ABS), and polypropylene. Each has different properties that make it more or less suitable for its particular application. For example, PVC is brittle, while ABS is stronger. HDPE is clear and can be printed with a design, so it is ideal for beverage bottles.

In TV shows, a bottle episode is an episode that’s filmed on a limited budget and features only main cast members. It’s usually filmed on a prebuilt (“standing”) set, doesn’t require any outdoor scenes or significant visual effects, and includes few guest stars. This makes it a cheap and quick way to put an episode together. The strictest definition of a bottle episode is an episode that doesn’t include any guest speaking roles or a full-sized house set, but some shows have more liberal criteria for what constitutes a bottle episode.

Glassmaking involves heating a mixture of minerals, typically soda ash, limestone and quartz sand, until it melts into a liquid. When it cools, it doesn’t crystallize into a conventional solid because the atoms are constantly moving. This gives glass its unique, somewhat spongy texture and properties. Scientists are exploring new ways to manipulate this disordered structure to improve its strength, color, or conductivity. They’re also focusing on ways to slow down the relaxation process, which could allow the material to move even closer to its crystallized state. This could make it possible to produce glass with a very precise, uniform, and stable properties.
