A bottle is a portable container used for carrying liquids, typically made of glass or plastic. Bottles can be filled with milk, juice, or other liquids. They often have a neck and mouthpiece that allows a baby to drink. Bottles can be a convenient way to feed babies and children when a breastfeeder is unavailable. A baby may not be willing to accept a bottle from someone other than its mother, but it will usually learn to take a bottle from a person who has been trained to give it to him.
Bottles can be crafted to meet many specific needs, and the ability to change their chemical composition during production makes it possible to achieve a wide range of desirable properties. For example, adding selenium to a glass composition changes its color and resistance to corrosion. The same process can also add a desired tensile strength to a glass structure.
In addition to changing chemical composition, it is possible to alter the physical characteristics of a bottle through additives or the use of heat. This is particularly common with glass used to make bottles for wine, beer and other alcoholic beverages. This type of bottle is often called a “wine bottle” or a “beer bottle.”
Glass bottles are often made of borosilicate (BPA-free) materials and are 100% recyclable. This is particularly important for reducing the amount of waste generated by the beverage industry. In fact, a single glass bottle can be recycled multiple times without losing quality or becoming brittle.
While breastfeeding is considered the best option for infant feeding, there are situations where bottle-feeding may be necessary for both medical and convenience reasons. In these instances, it is important to select a bottle that is comfortable for the child and that promotes healthy dental habits. It is a good idea to transition a child from the bottle to a regular cup by their first birthday.
A bottle episode is an episode of a television show that has been characterized as being unusual, standalone, or departing from the usual plotline for the season. In most cases, a television show will produce a bottle episode to cut costs in order to free up money for the production of more extravagant episodes. This can be due to the need for expensive special effects or the expense of building new sets. In most cases, a bottle episode will contain only main cast members and be filmed on one prebuilt set to keep costs down. This can also be done to avoid the cost of bringing in guest stars who are not on full-season contracts.
