A mug is a type of cup typically used for drinking hot drinks, such as coffee, hot chocolate, or tea. Mugs usually have handles and hold a larger amount of fluid than other types of cup. Travel mugs (introduced in the 1980s) generally employ thermal insulation properties for transporting hot or cold liquids. Similar to a vacuum flask, a travel mug is usually well-insulated and completely enclosed to prevent spillage or leaking, but will generally have an opening in the cover through which the contents can be consumed during transportation without spillage. As the primary mechanism by which hot (not warm) beverages lose heat is evaporation, a lid serves a vital role in keeping the drink hot; even a thin plastic one which conducts heat quite quickly. Mugs with inner and outer walls, but not vacuum treated, are generally called double wall mugs. Usually stainless steel will be used for the inner wall while outer wall can be stainless steel, plastic, or even embedded with other materials.

A water bottle is a container that is used to hold water, liquids or other beverages for consumption. The use of a water bottle allows an individual to drink and transport a beverage from one place to another. A water bottle is usually made of plastic, glass, or metal. Metal water bottles are preferable as the material is better for water bottles as they allow the liquid to stay colder or warmer for longer periods of time in different temperature environment conditions and are usually more durable than plastic and or glass. Water bottles are available in different shapes, colors, and sizes. In the past, water bottles were sometimes made of wood, bark, or animal skins such as leather, hide and sheepskin. Water bottles can be either disposable or reusable. Reusable water bottles can also be used for liquids such as juice, iced tea, alcoholic beverages, or soft drinks. Reusable water bottles reduce plastic waste and contribute to saving the environment. Easily portable, water bottles make for convenient use. Non-reusable water bottles often list nutrition facts.

Glass water bottles are heavier than plastic, stainless steel, or aluminium, and are easier to damage or completely break. Like metal, they also have a high level of temperature transfer, so they are not ideal for very hot or cold liquids. Some types of vacuum-insulated flasks use an inner layer of glass (which is easy to clean), and an outer layer of metal or plastic which helps shield the glass from breakage. Such bottles may still break if dropped, and thus some brands are triple-layer, with the glass inside two layers of plastic; this is a common configuration for large flasks intended for coffee or other liquids that need to be insulated. Stainless steel water bottles are growing in popularity, they are durable, and their previous contents retain less odor and taste than most plastic bottles, but can sometimes develop a metallic taste. Therefore, stainless steel bottles often contain resin or epoxy liners to protect the contents from taste and odor transfer or corrosion. Although most liners today are BPA-free, older and less expensive models can contain BPA and can also use glass liners. Metal (especially steel) water bottles can be heavier than their plastic counterparts. Single-walled metal bottles readily transfer temperature of contents to external surfaces, which makes them unsuitable for use with unusually hot or cold liquids. Double-walled metal bottles are insulated to keep cold liquids cold and hot liquids hot, without the external surface being too hot or too cold. Because double-walled bottles have more metal in them, they are more expensive. They are typically vacuum-insulated, but some may have a solid or gel insulation between the metal walls.
