This makes the association of using different colours for different products easier for the consumer.

Things to Consider with Trigger Sprayers

Referring to the diagram below, the overall trigger sprayer system consists of 12 components. Many of these components are made from a variety of materials, depending on the consumer's needs. To make sure you select the best system for your product, it is beneficial to review each of these components.

The Anatomy of the Trigger Sprayer

  • The Output of your Product

    What type of product you will be dispensing with the trigger sprayer, should be your first consideration? Certain ingredients can only be used with specific materials when considering components such as the ball, dip tube, etc. You will also need to determine what output will be needed from the sprayer. The output typically ranges from 0.7cc to 1.6cc.

  • The Dip Tube

    Another important component of the trigger sprayer that should not be overlooked is the dip tube. The length of the dip tube will need to tailored to work with the size of bottle you intend to use.

  • Which Nozzle to Use?

    The nozzle is an important aspect to consider when it comes to the consumer's needs. The nozzle gives the consumer control on how the product will dispense. There are several options available to the consumer. These options are:

    • A nozzle that simply twists open
    • A spout nozzle

How do Spray Bottles Pump Fluid?

October 5, 2021
Spray bottles are an extremely useful type of machine and an excellent demonstration of basic plumbing principles. A spray-bottle head is made up of only a few parts. It has a trigger lever, which activates a small pump. This pump is attached to a plastic tube that draws cleaning fluid from the bottom of the reservoir. The pump forces this liquid down a narrow barrel and out a small hole at the gun's muzzle. The hole, or nozzle, serves to focus the flowing liquid so that it forms a concentrated stream.  The only complex element in this design is the fluid pump, and it's about as simple as they come. The main moving element is a piston, housed inside a cylinder. Inside the cylinder, there is a small spring. To operate the pump, you pull the trigger back, pushing the piston into the cylinder. The moving piston compresses the spring, so when you release the trigger, the piston is pushed back out of the cylinder. These two strokes of the piston, into the cylinder and out again, constitute the entire pump cycle.

What is an Atomizer and Why Should I Use It?

October 5, 2021
Atomizers convert streams of liquid into fine sprays. They’re used in everyday applications to control the amount of liquid being released and dispersed from a container. Used frequently in homes for everyday cooking and cleaning, they’re also good for a variety of other purposes. The most basic components of an atomizer are a bottle filled with liquid and a tube that connects to a nozzle. The nozzle always has a screen inside. That screen disperses the liquid particles to create a mist.
