Bottle-cap Box





Introduction: Bottle-cap Box


I made a box for storing candy, medicines, money or whatever you want. I made it from two bottle-caps.

This is my second Instructable.

A cap= the cap from a plastic bottle

A bottle=a plastic bottle.

Step 1: What You Will Need:

You will need:

  • Scissors
  • Stanley knife
  • A clean cap
  • A clean bottle with cap
  • Hot glue gun
  • Cutting board

Step 2: Cut

Cut the plastic bottle with a stanley knife. Now, you have something like the second image. Then, cut with scissors. You must leave some (hard) plastic at the cap. If you are finished, you must have something like the third image.

Step 3: Glue

Glue the lonely red cap with four dots on the plastic that you have left behind. After that, you have something that looks like the second image.

Step 4: Finishing

Turn the cap tight to the rest and you are done. If you want to open it, turn the cap off.

Love this! Use it when go backpacking. (seasoning, soap, and pills)---Thanks!

You got me inspired! I'm going to try a larger version. Peanut butter jars. Big enough to put a door key in. Bury it in my flowers for an emergency spare.

Never thought of changing the size! Many possibilities! Thanks for the idea!

good idea. Hope to see the finished product

This has been done many many times already. Mine was made for Geocaching also, and is waterproof. Have even done to place a thin piece of plastic in middle so it separates as 2 compartments.

bro send me one as a gift its my birthday next month! i will always remember u in my prayers.

What a great idea! Also leaves room for innovations as shown by comments below. Well done, you!!

Instead of sticking them with glue, try hammering them. Less materials required, less mess :) (but chances are it won't be watertight)

Just be aware: these are used by pill junkies and will give probable cause to search if stopped by police for any reason.

they would have to already be searching in order to find these.

No, I designed and made it myself.

th e king of random had been out for months

I never saw king of random. And I never posted or bragged about doing something like this but *I* made these 15+ years ago. And still do. Just because the author came up with the same idea on his own that *I* did on *my* own doesn't mean he copied me -- nor did the king of random copy me. Nor I him.

I've been tweaking things for 30+ years and have seen many of things I came up with on my own posted on the internet. I never suspected they stole from me. All that means is "great minds think alike" or more likely that "some things are bloody obvious" when trying to solve a problem

I see here that the author inspired a few people. Good Job!

It's a great Idea especially if it's water proof but latly people have just been copying other people's projects and not giving credit. this one deserves the king of random credit.

you are great, i am keen to study and work with creative people like you. thanks buddy

Ive seen the King of Randoms version of this but this one is really simple and easy to make!

Really ingenious idea!
