A spray bottle is a bottle that can squirt, spray or mist fluids.
A spray bottle is a bottle that can squirt, spray or mist fluids.
While spray bottles existed long before the middle of the 20th century, they used a rubber bulb which was squeezed to produce the spray; the quickly-moving air siphoned fluid from the bottle. The rapid improvement in plastics after World War II increased the range of fluids that could be dispensed, and reduced the cost of the sprayers because assembly could be fully automated.
The Drackett company, manufacturers of Windex glass cleaner, was a leader in promoting spray bottles. Roger Drackett raised soybeans, converted the soybeans to plastic using technology purchased from Henry Ford, and was an investor in the Seaquist company, an early manufacturer of sprayers and closures. Initially, the brittle nature of early plastics required that sprayers be packaged in a cardboard box, and the sprayer inserted in the glass Windex bottle by the consumer. The cost in the manufacturing sprayers was also a factor; consumers would reuse the sprayers with bottle after bottle of glass cleaner. As plastics improved and the cost of sprayers dropped, manufacturers were able to ship products with the sprayer already in the bottle.
In the late 1960s, spray bottles with trigger-style actuators appeared and quickly became popular, as this design was less fatiguing to use. The original pump-style bottle remained more popular for applications like non-aerosol deodorants, where size was a factor and repeated pumps were not required.
Unlike the rubber bulb dispenser which primarily moved air with a small amount of fluid, modern spray bottles use a positive displacement pump that acts directly on the fluid. The pump draws liquid up a siphon tube from the bottom of the bottle and forces it through a nozzle. Depending on the sprayer, the nozzle may or may not be adjustable, so as to select between squirting a stream, aerosolizing a mist, or dispensing a spray.
In a spray bottle, the dispensing is powered by the user's efforts, as opposed to the spray can, in which the user simply actuates a valve and product is dispensed under pressure.
Several designs have been developed. [1] [2] [3] Some of the pumping mechanisms of spray bottles are similar to those of pump dispensers which are used for more viscous products.
A water gun is a type of toy gun designed to shoot jets of water. Similar to water balloons, the primary purpose of the toy is to soak another person in a recreational game such as water fight.
Spray painting is a painting technique in which a device sprays coating material through the air onto a surface. The most common types employ compressed gas—usually air—to atomize and direct the paint particles.
Aerosol spray is a type of dispensing system which creates an aerosol mist of liquid particles. It comprises a can or bottle that contains a payload, and a propellant under pressure. When the container's valve is opened, the payload is forced out of a small opening and emerges as an aerosol or mist.
In medicine, a nebulizer or nebuliser is a drug delivery device used to administer medication in the form of a mist inhaled into the lungs. Nebulizers are commonly used for the treatment of asthma, cystic fibrosis, COPD and other respiratory diseases or disorders. They use oxygen, compressed air or ultrasonic power to break up solutions and suspensions into small aerosol droplets that are inhaled from the mouthpiece of the device. An aerosol is a mixture of gas and solid or liquid particles.
Air fresheners are consumer products that typically emit fragrance and are used in homes or commercial interiors such as restrooms, foyers, hallways, vestibules and other smaller indoor areas, as well as larger areas such as hotel lobbies, auto dealerships, medical facilities, public arenas and other large interior spaces. Car fresheners are used in automobiles. As a source of odors, specific deodorizing blocks are made for toilets and urinals.
A closure is a device used to close or seal a container such as a bottle, jug, jar, tube, or can. A closure may be a cap, cover, lid, plug, liner, or the like. The part of the container to which the closure is applied is called the finish.
A soap dispenser is a device that, when manipulated or triggered appropriately, dispenses soap. It can be manually operated using a handle or can be automatic. Soap dispensers are often found in public toilets.
The soda siphon, also known as the seltzer bottle or siphon seltzer bottle, is a device for storing and dispensing carbonated beverages while maintaining the internal pressure, thereby preventing it from going flat.
A sprayer is a device used to spray a liquid, where sprayers are commonly used for projection of water, weed killers, crop performance materials, pest maintenance chemicals, as well as manufacturing and production line ingredients. In agriculture, a sprayer is a piece of equipment that is used to apply herbicides, pesticides, and fertilizers on agricultural crops. Sprayers range in size from man-portable units to trailed sprayers that are connected to a tractor, to self-propelled units similar to tractors with boom mounts of 4–30 feet (1.2–9.1 m) up to 60–151 feet (18–46 m) in length depending on engineering design for tractor and land size.
A spray nozzle or atomizer is a device that facilitates the dispersion of a liquid by the formation of a spray. The production of a spray requires the fragmentation of liquid structures, such as liquid sheets or ligaments, into droplets, often by using kinetic energy to overcome the cost of creating additional surface area. A wide variety of spray nozzles exist, that make use of one or multiple liquid breakup mechanisms, which can be divided into three categories: liquid sheet breakup, jets and capillary waves. Spray nozzles are of great importance for many applications, where the spray nozzle is designed to have the right spray characteristics.
A Flit gun is a hand-pumped insecticide sprayer used to dispense FLIT, a brand-name insecticide widely used against flies and mosquitoes between 1928 and the mid-1950s. Although named after the well-known brand, "Flit gun" became a generic name for this type of dispenser. Once commonly found in households, hand-operated Flit guns have been replaced by aerosol spray cans and fallen out of common use.
Pesticide application refers to the practical way in which pesticides are delivered to their biological targets. Public concern about the use of pesticides has highlighted the need to make this process as efficient as possible, in order to minimise their release into the environment and human exposure. The practice of pest management by the rational application of pesticides is supremely multi-disciplinary, combining many aspects of biology and chemistry with: agronomy, engineering, meteorology, socio-economics and public health, together with newer disciplines such as biotechnology and information science.
Ultra-low volume (ULV) application of pesticides has been defined as spraying at a Volume Application Rate (VAR) of less than 5 L/ha for field crops or less than 50 L/ha for tree/bush crops. VARs of 0.25 – 2 L/ha are typical for aerial ULV application to forest or migratory pests.
Ultrasonic nozzles are a type of spray nozzle that use high frequency vibrations produced by piezoelectric transducers acting upon the nozzle tip that create capillary waves in a liquid film. Once the amplitude of the capillary waves reaches a critical height, they become too tall to support themselves and tiny droplets fall off the tip of each wave resulting in atomization.
Microdispensing is the technique of producing liquid media dosages in volumes of less than one microlitre. The continuing miniaturization in almost all technical areas creates constant challenges for industry, development and research facilities. Microdispensing is one of those challenges. Ever smaller amounts of adhesive, liquid, oil, grease and a multitude of other media must be dispensed reliably and accurately in dosage and placement with short cycle times. The precise positioning and quantity of fluids such as glue, reagents or any other substance has a great influence on the overall quality of a medical device. A few examples are:
A squeeze bottle is a type of container such as a plastic bottle for dispensing a fluid, that is powered by squeezing the container by exerting pressure with the user's hand. Its fundamental characteristic is that manual pressure applied to a resilient hollow body is harnessed to compress fluid within it and thereby expel the fluid through some form of nozzle.
A gasoline pump or fuel dispenser is a machine at a filling station that is used to pump gasoline (petrol), diesel, or other types of liquid fuel into vehicles. Gasoline pumps are also known as bowsers or petrol bowsers, petrol pumps, or gas pumps.
A spray is a dynamic collection of drops dispersed in a gas. The process of forming a spray is known as atomization. A spray nozzle is the device used to generate a spray. The two main uses of sprays are to distribute material over a cross-section and to generate liquid surface area. There are thousands of applications in which sprays allow material to be used most efficiently. The spray characteristics required must be understood in order to select the most appropriate technology, optimal device and size.
A media dispenser or a culture media dispenser is a device for repeatedly delivering small fixed volumes of liquid such as a laboratory growth medium like molten agar or caustic or volatile solvents like toluene into a series of receptacles. It is often important that such dispensers operate without biological or chemical contamination, and so must be internally sealed from the environment and designed for easy cleaning and sterilization before use. At a minimum, a media dispenser consists of some kind of pump connected to a length of discharge tubing or a spout. Dispensers used in laboratories are also frequently connected to microcontrollers to regulate the speed and volume of the medium as it leaves the pump.
A pump dispenser is used on containers of liquids to help dispensing. They might be used on bottles, jars, or tubes. Often the contents are viscous liquids such as creams and lotions. Some are metered to provide uniform usage. Some mix contents from two or more sources prior to dispensing.
