The following steps show you how to make a safety razor case out of a prescription bottle. This case is somewhat child resistant and shouldn't open up by itself when taken traveling.
I first saw this idea posted in the wicked_edge section of Reddit from a user named Qndrez. Full credit for the original design goes to them. The idea was so simple and brilliant that I felt compelled to create an Instructable about it.
Step 1: Gather Your Supplies
You will want the following:
- Prescription bottle ( With the label removed if it is not your prescribed bottle due to legal reasons. )
- Exacto Knife or Similar ( Preferably with an old blade you will not use again. )
- Lighter or other flame source
- Safety Razor
Step 2: Mark Your Bottle
Get out the safety razor you plan to store in the bottle. It is best to have it assembled without the blade in it for these steps. With the side of the razor head flush against the top of the bottle make a mark slightly below the bottom side of the neck of the handle as shown. This marks how deep you will need to cut in the next step.
Step 3: Cut the Prescription Bottle
First, make sure you are in a well-ventilated area. You will be burning through plastic soon and it is not a good idea to breathe in those fumes.
Next, use your lighter or another flame source to heat up a sharp blade. With the cap removed use your hot blade to cut from the top of the bottle to the mark that you made earlier. Cut another parallel line down to this same depth, the distance between these should be slightly bigger than the smallest part of the neck of your safety razor. In my case the width was about one centimeter. You will likely have to re-heat your sharp blade multiple times to make all necessary cuts.
Then cut from the bottom of both of your first two slices so that they meet each other and remove this whole rectangular section from the bottle.
Step 4: Assemble
Place your assembled safety razor into the bottle and attach the lid. You now have your very own child resistant safety razor travel case. You should be able to store your safety razor with a blade still attached with little risk of the container coming open accidentally.
Depending on the size of your bottle you may have enough room for extra blades and even a bit of soap. Take care to dry your safety razor before storing it in this container as you don't want it to turn into a bacteria trap.
