A trigger sprayer is a spraying tool designed to apply chemicals or other products to specific areas. It comes in many styles and sizes, including those with foaming features, upside down nozzles, and hose extensions. These sprayers are often used for air care, automotive and fabric cleaning, as well as for insect control and lawn and garden applications.
A trigger sprayer dispenses liquids directly onto a surface with precision and repeatability. The trigger sprayer's adjustable nozzle provides precise control over the amount of liquid dispensed. The trigger is lightweight and leak-proof, making it easy to transport. It is also suitable for standard 28mm/400-neck bottles.
Plastic trigger sprayers were first developed as a way to distribute liquid products through retail outlets. They are typically made of polypropylene or HDPE plastic, which offer great impact and moisture barrier properties. They are also equipped with an adjustable trigger sprayer nozzle that allows for various spray patterns, including fine mist, coarse mist, and a jet stream.
The trigger sprayer 20 of the present invention includes fewer parts and a horizontal trigger 24 motion, which provides desired ergonomics. Ordinary persons of skill may desire to control the particle size distribution of the liquid. If the spray particles are too large, they will fall onto the floor while too small particles will create a wet spot. The smallest spray particles, however, may remain suspended until evaporation occurs. However, if the particles are too small, they may end up in a spot that is unsightly.
Trigger sprayers are widely used for household cleaning products. They are expected to be in high demand in 2020 due to the pandemic affecting the COVID virus. A trigger sprayer is a very useful tool that allows you to control the amount of contents dispensed. The trigger sprayer is adjustable, so it is important to know the exact amount you want before using it.
The actuation force was measured at a distance of 40 mm from the pivot of the trigger 24. The Yuanyuan Plastic sprayer 20 consistently had the highest actuation force. The sprayer's peak actuation force was 18.1 N for the test liquid and 20.6 N for distilled water. The force increased to 62 N when it was operating at 90 SPM. This is a significant increase in actuation force.
