How to Make Your Own Hand Sanitizer Dispenser

3 hand sanitizer dispenser designs

Need a dispenser for the hand sanitizer you have purchased for your company? While some companies are buying automatic, non-contact hand sanitizer dispensers, more industrious operations management might engage internal resources to build their own. Especially if you have engineers in the company that like these kinds of projects.

In this article, we review how to make three different designs that let you create DIY dispensers, that you can add to your PPE kit

Hacktuber Non-contact Hand Sanitizer Dispenser

The first one we are going to look at comes from HackTuber on Youtube. This hand sanitizer dispenser is easy to make and budget-friendly. It requires materials that many companies might have on hand (eg. wood) and a few parts you may need to purchase (e.g. infrared sensor) that can be acquired for a few dollars.

Overall, it the build is straightforward, not very labor-intensive, and is doable for someone with minimal experience with tools and electronics.

What you’ll need: 

  • Infrared red sensor with 5V relay
  • DC Motor 
  • Wood  
  • Glue
  • Tools
  • Hand sanitizer with a built-in pump

How to make it:

Figure 1. 2
Figure 1. 3
  • Attach a piece of wood to the DC motor. This will rotate. 
  • Create a wood base that will hold the sanitizer in place securely. 
    • Cut 3 rectangles – 2 small ones (to secure the bottle) and one larger one (as the base). 
    • Glue the smaller rectangles to the larger rectangle. 
Figure 1. 4
  • Cut another thin rectangle and attach the DC motor to it. Attach it to the base. 
    • Make sure the wood attached to the DC motor will be close enough to hit the dispenser pump of the hand sanitizer bottle. 
  • Secure all the pieces with glue and connect the motor to a power source. 
Use the Hand Sanitizer Dispenser by hovering your hand over it

  • How to use: 
    •  Hover hand over the sensor. The sensor will power the motor and the wood attached to the motor will hit the pump and dispense hand sanitizer.

Mini Gear Hand Sanitizer Dispenser 

The next automatic hand sanitizer dispenser comes from Mini Gear on Youtube. This dispenser is a little more complicated and labor-intensive than the first one. However, many of the equipment needed can be found in your home (ex. cardboard) or are cheap to purchase (ex. 9V battery). Additionally, it can be made mostly or completely by hand and does not require the use of tools like a hand drill or a screwdriver. Overall, it is fairly straightforward and doable for someone at a beginner to intermediate skill level.  

What you need: 

  • Cardboard 
  •  9v battery and wire connector 
  • Air-bump DC motor 
  • Popsicle stick 
  • BBQ bamboo stick (skewer) 
  •  Fishing Wire 
  • Rubber Band 
  • Syringe Tubing 
  • Plastic Bottle

  • Finish the dispenser: 
    • Connect the circuit, sensors, and the motor to a power source. Secure on to the dispenser base.
    • Place a hand sanitizer bottle on to the dispenser. 
  • How to use: 
    • Move your hands over sensors and the mechanism will move and press down on the dispenser pump. 

Final notes about these hand sanitizer dispensers: 

These three hand sanitizer dispensers differ on materials, price, and difficulty level. The ones made by Mini Gear and Hacktuber would be more suited to those will minimum experience with tools or electrical equipment. Whereas, the one made by Mr. Innovative would be better for someone with greater experiences with those things. Nonetheless, they are all straight forward and effective DIY Hand sanitizer dispensers for you to make.
