A foam pump

A foam pump, or squeeze foamer and dispensing device is a non-aerosol way of dispensing liquid materials. [1] The foam pump outputs the liquid in the form of foam and it is operated by squeezing. The parts of the foam pump, mostly made from polypropylene (PP), are similar to those of other pump devices. The foaming pump often comes with a protective cap.

Operation

A foam pump dispenses doses of the liquid contained in the bottle in the form of foam. Foam is created in the foaming chamber. The liquid constituents are mixed in the foaming chamber and this is discharged through a nylon mesh. The neck finish size of a foam pump is bigger than the neck finish size of other types of pumps, to accommodate the foamer chamber. The usual neck size of a foam pump is 40 or 43mm.

Where hair-coloring products previously contained instructions to vigorously shake the product, squeeze the bottle, and turn upside-down to disperse the product, foamers do not require any such actions.[ citation needed ] Some foaming dispensers include suction on the bottom to allow the container to remain upright.

Foamers can be purchased alone, or filled with a liquid product like soap. When the liquid is mixed with air, the liquid product can be dispersed through the pump-top as a foam. Foamers can also be re-used with different liquid products to extend the mass of the liquid by creating a foam-version. [2]

Applications

The foam pump is widely used for dispensing cosmetic products and household chemicals, such as mousse foam cleansing, hand washing liquid, hand sanitizer, facial cleanser, shaving cream, hair conditioning mousse, sun protection foam, spot removers, baby products, and so on. In the field of food and beverages, molecular gastronomy style foam is usually created using various techniques and stabilizers such as lecithin, but there is at least one ready-to-use liqueur that has been developed with the foaming apparatus top that produces an alcoholic foam topping for drinks.

A vacuum flask is an insulating storage vessel that slows the speed at which its contents change in temperature. It greatly lengthens the time over which its contents remain hotter or cooler than the flask's surroundings by trying to be as adiabatic as possible. Invented by Sir James Dewar in 1892, the vacuum flask consists of two flasks, placed one within the other and joined at the neck. The gap between the two flasks is partially evacuated of air, creating a near-vacuum which significantly reduces heat transfer by conduction or convection. When used to hold cold liquids, this also virtually eliminates condensation on the outside of the flask.

A bottle cap or bottle top is a closure for the top opening of a bottle. A cap is sometimes colorfully decorated with the logo of the brand of contents. Plastic caps are used for plastic bottles, while metal with plastic backing is used for glass; plastic caps are commonly made from polyethylene or polypropylene, while metal caps are usually either steel or aluminum. Plastic caps may have a pour spout. Flip-Top caps like Flapper closures provide controlled dispensing of dry products. Caps for plastic bottles are often made of a different type of plastic from the bottle.

Glass microspheres are microscopic spheres of glass manufactured for a wide variety of uses in research, medicine, consumer goods and various industries. Glass microspheres are usually between 1 and 1000 micrometers in diameter, although the sizes can range from 100 nanometers to 5 millimeters in diameter. Hollow glass microspheres, sometimes termed microballoons or glass bubbles, have diameters ranging from 10 to 300 micrometers.

A high-shear mixer disperses, or transports, one phase or ingredient into a main continuous phase (liquid), with which it would normally be immiscible. A rotor or impeller, together with a stationary component known as a stator, or an array of rotors and stators, is used either in a tank containing the solution to be mixed, or in a pipe through which the solution passes, to create shear. A high-shear mixer can be used to create emulsions, suspensions, lyosols, and granular products. It is used in the adhesives, chemical, cosmetic, food, pharmaceutical, and plastics industries for emulsification, homogenization, particle size reduction, and dispersion.

Drum pump, barrel pump, and transfer pump refer to pumps that are used to empty barrels, tanks, IBCs and drums. Many liquids used on manufacturing and processing plants are delivered in 100 or 200 litre barrels and are too heavy to tip to empty the liquids inside. Drum pumps range from simple siphon based devices to sophisticated highly-engineered machinery.

<span class="mw-page-title-main">Media dispenser</span>


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.

<span class="mw-page-title-main">Pump dispenser</span>

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.
