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

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

Never though about that. Great idea.

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.

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

This is excellent - beside the many other suggestions, this should be perfect for small amounts of ointment, powder, polish - and the tiny screws one always drops after opening equipment. The plastic being insulative, one could encapsulate extra/removed screws and drop this inside the casing without fear. Thanks! :D
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.

 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)  pugsleyboy3 years ago
thanks for the comment. It was my first instructable. You are right. Epoxy does wotk better.
 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.

thats true. I didnt think about geocaches. Thanks
