Introduction: Foam Pump Mason Jar Soap Dispenser

Create your own foam pump mason jar soap dispenser from material that you may already have in your home.

Did you know that the foam soap that you buy at the store contains mostly water and that it is actually the pump itself that creates the majority of the foam?  Save yourself some money by diluting 6 parts water to 1 part of your favorite liquid soap.  

Think about it...only 2 oz of liquid soap will fill your pint sized widemouth mason jar.






Step 1: What You Are Going to Need

Use of hardware is required for this instructable and should not be attempted by anyone who is not familiar with the tools used for this project.

* Wide mouth mason jar with lid, band and jar
*  Clean foam pump with the bottle (you can reuse one that you already have, just clean it out)
*  Drill
*  Bi-metal hole saw (most likely 1 1/2 or 1 3/4)
*  A press to hold the lids in place
*  Lubricating oil for saw
*  Epoxy, water sealant, or any other waterproof glue
*  Metal file
*  Junior hacksaw
*  Permanent marker
*  Gloves and goggles

Okay, you ready?
You got this, you can do it :)

Step 2: Measure It

First you will want to measure the circumference of the circle that you will be cutting by comparing it to the bottle you will be using.  Make sure that the hole will pass the threading without going all the way thru the outside bottle

Step 3: Mark It

Mark the center of the lid with your pen.  No need to make it fancy, unless you wanna, just take note of the center.

Step 4: Line It Up

We rigged up some boards that stand off the floor to hold the lid in place and keep it from moving. Use a press and make sure that the lid is secure and tight because, when the drill comes down it is going to want to slide out from under you and you need to make sure that it will not slide out from under ya.

Step 5: Secure It

Make sure you have the lid FIRMLY pressed down, you do not want it spinning out when you start drilling. Gloves and goggles would be a great idea to put on if you haven’t already.  Remember kids... Safety First :)

Step 6: Lube It

Add oil to aid the hole saw. This will help with maintaning the saw and achieving a cleaner cut.

Step 7: The First Cut

Aim the pilot bit thru the center of the lid and pause once you have passed all the way thru.

Step 8: Here We Go

Check yourself to make sure that you are level to the lid. Fire up the drill at full force but, LIGHTLY skim the top of the lid and apply pressure as evenly as possible. Stop when you go thru all the way.

Step 9: :O

And there you go, it’s a hole!

Step 10: Great Job...now Do It Again

Repeat the process to make a second lid. 

WEEEEEEEE!! Again!!! Again!!!!




Step 11: Clean It Up

File away if you need to fit the shape of the bottle and/or to remove any bits of metal

Step 12: Now the Bottle

Cut below the ridge with your junior hacksaw, about half an inch or so, leaving enough space on the bottle to be able to tuck under the lid.

Step 13: Making Tabs

Cut slats across the circumference of the bottom of the cut bottle because, this will allow you to bend the plastic back to better seal the lid.

Step 14: Get It Together

Get out your glue and let's assemble. 

Step 15: Assemble

(click here if you do not see animation)
Basicly, you sandwich the plastic threading between the two lids and make sure there is plenty of glue around the edging to prevent leaks and separation.  

Step 16: Oops!

Be careful not to get the glue on the threading and if you do just, wipe it off with a damp towel.  Just be careful with the glue period.

Step 17: Getting Situated

We found it best to have the glue cure while all the pieces were in position.  Place the lid on top of the jar and apply pressure evenly in the center to press the lids together. Secure with the band and let the sealant cure.

Step 18: Finishing Touches

After the glue has dried, flip the lid over and apply sealant around any loose edges. 

Step 19: That's How It's Done!

Congrats to you! Paint to suit your needs and enjoy!

Thanks, Flavrt :)

Agreed! The soap that is sold in mainstream retail is full of different types of chemicals, so much that they can no longer be considered "soap" They have labels such as liquids, gels, detergent etc.

Figured out a few years back about the soap industry and how they were trying to one us over by making us think that it was the soap that was causing it to foam so much when in truth, it is just the pump forcing air into the water and soap mix. (Think like what a sponge does when you squeeze it in soapy water)

It's a matter of preference on the dilution rate that you would like to use. Found that anywhere between 1/3 ratio and 1/10 worked with the pump. Just keep in mind that if the mix is too thick it will clog the pump and if it is too thin, it can wear out the lubrication in the spring.  We give the ratio of 1/6 for the soap that we sell.

Very good. You scooped me.

We like foaming hand soap, but it is crazy expensive. And they warn that the dispenser will not work right with ordinary liquid soap. Ha, because it is so diluted. I've been mixing 1 part soap to 3 parts water, which works fine.

Best of luck with OSSC. I hope you find a big market for unscented soap. Who wants to work with vegetables with chemical fragrance permeating their hands?
