Introduction: Bottle Cap Container

Picture of Bottle Cap Container

This is a very simple container to make using a plastic bottle and 2 plastic bottle caps.

Step 1: Cutting Plastic Bottle

Simply cut the plastic bottle right above the rim or the of the upper side of the rim

Step 2: Assemble the Cap

After you have cut the top of the plastic bottle, take a hot glue gun and glue the cap to the top of the bottle (the cut side). It should fit right to the threads. Do not thread it as there are only enough threads for the other cap.

Step 3: Finished Product

After the glue sets and hardens, you will be able to screw on the other cap. This was an easy project and plus you are recylcling. I dont know what this could be used for other than for storing a couple of pills. Please reply. This is my first Instructable

I've found that the hot glue didn't hold firmly enough (admittedly I was using milk bottle lids and not soft drink ones). I was using it as a geocache which had many different people opening and closing it. Still working to refine the idea to make it more durable.

You could try using a milk bottle or peanut butter lid, so you can make bigger ones.

Made it... A little different... I don't have time to go to Walmart and this also saves me money... Thanks for the idea

A case for an extra hearing aid battery.

To be honest, I don't quite get this 'ible. Can't call this recycling except for a tiny percentage of the bottle, and you can get quite well-made tiny plastic jars cheap at dollar stores.WalMart, etc.

Here's a bag of 50 of 'em for $20 on eBay - which comes down to 40 cents each, I think.

Or, get some Eos lip balm - after you've used the product, you'll have a better version of this DIY hot-glued container. In fact, you gals especially probably throw out a lot of makeup pots of about this same size.

If you make your own lip balm, you might be able to use this as a container for it.

Thanks so much for this. It is exactly what I need. I ride the subway every day and the noise coming from so many tinny buds and headphones drives me crazy so I bring a pair of earplugs with me. Most of the time I can only find one earplug. Digging around fruitlessly in pockets or my purse... now I can dig around instead for this perfect little container, which will be so much easier to find than those illusive, soft little earplugs, and also I can keep them together at all times. Really, it is perfect!

Great idea. I think I will do the same. Thanks for the idea. Glad you like it.

What a great idea, so simple. Now if your a camper or backpacker, you could poke a few holes in one of the caps, put in salt and pepper, use a small piece of stretch wrap to keep the spices in and you have a very compact salt and pepper shaker. Love the idea

etgainey (author)DoDo7292012-05-31

Never though about that. Great idea.

etgainey (author)Kanein Encanto2012-05-31

Yes I know. I seen that one too. I just liked having the caps flush against each other. Its all about personal preference.

So? I fail to see your point.

How did you cut the neck? I ended up successfully cutting 4 bottles with a pvc pipe cutter, but it would occasionally cut them a bit skewed.

etgainey (author)Khord2012-05-31

I just used a razor knife and trimmed it up.

Its a great way to recycle plastic bottle caps. You could use it to store small things like shirt-buttons, small pins,paper nails etc..Thanks.

This is a GREAT idea!!  I have a medical condition that makes it wise to have certain meds with me.  This will be an easy way to keep them handy! :)

FuzzyBearGeek (author)Browncoat2011-08-14

Ditto. This is so simple and elegant. That makes it outstanding!

Perfect for gatorade lids or other large mouth beverages.Small containers like this are great for beaders and other crafty types!

Could be used for storing screws say for Laptop or other small device. If your taking it apart for repair and it will be apart for a day or two then this would keep your screws safe. Maybe a few of these screwcap storage units together, I know I like to keep the screws for different parts of the laptop separate so I know where and when they go back.

Nice idea, may be you can use it for geocache container.

etgainey (author)ChrysN2010-05-31

i did not think of that . You are right. Thanks for the reply and idea

Eye Poker (author)2010-05-30

You could attach it to a fishing line for a bobber.

etgainey (author)Eye Poker2010-05-31

thats true. Thanks for the idea

 It's similar to brantflakes315's instructable but i prefer yours, it's a lot sleeker because you can't see the bottle neck, I just made one from 2 sprite lids and used epoxy instead of hot glue

etgainey (author)pugsleyboy2010-05-31

thanks for the comment. It was my first instructable. You are right. Epoxy does wotk better.

BrantFlakes315 (author)2010-05-31

 Nice job on this one; it is a bit different than mine. You seem to cut off the entire neck, and use glue to hold on the top. If you leave on part of the neck (the straight part) , you can just jam the other cap on for a pretty good seal.

They do make good geocaches too. I have two out in the wild and they are holding up really well so far.

etgainey (author)BrantFlakes3152010-05-31

thats true. I didnt think about geocaches. Thanks
