Disposable product in the context of "Indian pottery"

An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. The terminal marked negative is the source of electrons. When a battery is connected to an external electric load, those negatively charged electrons flow through the circuit and reach the positive terminal, thus causing a redox reaction by attracting positively charged ions, or cations. Thus, higher energy reactants are converted to lower energy products, and the free-energy difference is delivered to the external circuit as electrical energy. Historically the term "battery" specifically referred to a device composed of multiple cells; however, the usage has evolved to include devices composed of a single cell.

Primary (single-use or "disposable") batteries are used once and discarded, as the electrode materials are irreversibly changed during discharge; a common example is the alkaline battery used for flashlights and a multitude of portable electronic devices. Secondary (rechargeable) batteries can be discharged and recharged multiple times using an applied electric current; the original composition of the electrodes can be restored by reverse current. Examples include the lead–acid batteries used in vehicles and lithium-ion batteries used for portable electronics such as laptops and mobile phones.

A packet or sachet is a small bag or pouch, made from paper, foil, plastic film or another type of packing material, often used to contain single-use quantities of foods or consumer goods such as ketchup or shampoo. Packets are commonly opened by making a small rip or tear in part of the package, and then squeezing out the contents.

A drinking straw is a utensil that uses suction to carry the contents of a beverage to one's mouth. A straw is used by placing one end in the mouth and the other in a beverage. Lowering the pressure in the mouth (i.e. applying suction) causes the surrounding atmospheric pressure to force the liquid through the straw and into the mouth. Drinking straws can be straight or have an angle-adjustable bellows segment.

Disposable straws are commonly made from plastics. However, environmental concerns related to plastic pollution and new regulation have led to rise in reusable and biodegradable straws. Following a rise in regulation and public concern, some companies have voluntarily banned or reduced the number of plastic straws used. Alternative straws are often made of reusable materials like silicone or metal or alternative disposable and biodegradable materials like paper, cardboard, pasta, or bamboo.

Consumables are goods that are intended to be used up, or in the case of food, eaten. People have, for example, always consumed food and water. Consumables are in contrast to long-lasting durable goods such as cars and washing machines. Disposable products are a particular, extreme case of consumables, because their end-of-life is reached after a single use.

Consumables are products that consumers use recurrently, i.e., items which "get used up" or discarded. For example, consumable office supplies are such products as paper, pens, file folders, Post-it notes, and toner or ink cartridges. This is in contrast to capital goods or durable goods in the office, such as computers, fax machines, and other business machines or office furniture. Sometimes a company sells a durable good at an attractively low price in the hopes that the consumer will then buy the consumables that go with it at a price providing a higher margin. Printers and ink cartridges are an example, as are cameras and film as well as razors and blades, which gave this business model its usual name (the razor and blades model).

A bento (弁当, bentō) is a single-portion take-out or home-packed meal of Japanese origin, often for lunch, typically including rice and packaged in a box with a lid (often a segmented box with different parts of the meal placed in different sections).

A traditional bento typically includes rice or noodles with fish or some other meat, often with pickled and cooked vegetables in a box. Containers range from mass-produced disposable containers to hand-crafted lacquerware. Dividers are often used to separate ingredients or dishes, especially those with strong flavors, to avoid them affecting the taste of the rest of the meal. A typical divider is green plastic 'sushi grass', known as baran in Japan, which also works to slow the growth of bacteria.
