Cobalt Blue Tube Vaults
We have been selling the U.S. Military Tube Vaults for years as a way to organize and store oral and injectable medications in the field. These Tube Vauts are food and pharmaceutical grade, crush resistant (not much in life is "crush proof") polyethylene terephthalate (PET). They come with air tight, liquid tight tamper evident caps. They are also dishwasher safe and made in the USA.
We also still provide them in a Clear: Link Here
And now in Transclucent Cobalt Blue, that provides some visual identification. (Tube Vault internal volume: 40ml or 1.35oz, Interior 5.70” Deep x .65" Wide)
External 6" Length x 1.35" wide at head
Once we had them in our hands we discovered their uses were endless.
How our staff members are using them: some have already liberated for the following purposes: geocaching, sewing kits, detergent for those trips to the Laundromat, flavored drink concentrates, thermometers, cotton swabs, mini survival capsule, the ultimate match safe, 4 ea. spare CR123 batteries, emergency money, tea, spices and sugar. Carry a double dose of cold medicine into the field leaving the big bottle at home. The possible uses are endless. Note: Cobalt Blue Tube Vault DOES NOT fit 18650 battery, The Clear Tube Vault does fit 18650 batteries.
How is Uncle Sam using tube vaults? Military Pharmacists insert glass medication bottles inside the vaults, then they screw on the tamper evident seals and then issue them to the Medics in the field. The pharmacists can even scan bar codes through the vault. Once the medication is in the field, the vaults protect the glass medication vials from dirt, dust and crushing. When the Medic returns from the field, doing inventory of his pharmaceuticals is easy. If the tamper resistant seal is in place the medication wasn't used. If the seal is broken, it's been used and needs to be replaced. They can even rinse the dust off the outside without getting the inside contents moist. How will you use yours?
Tube Vault comes with 1 white tamper proof cap.
Also available: International Orange tamper proof cap pack (10 Caps per pack)
Highly versatile, super strong construction and the blue vaults are easy to identify among the clear ones. Add the orange colored tops and they're even more accessible. Highly recommended.
Storing a Fountain Pen in this tube vault can extend the time interval for required cleaning of your pen nib due to dried ink when not used frequently. If you are a fountain pen fancier, you will recognize the value of this simple solution, storing fountain pens filled with ink. Slowing the evaporation of the ink stored in your pen and reducing the frequency of the required cleaning of your fountain pens.
So these are not made to hold liquids. and the lids don't look like they will hold up to a lot of use. But for the cost they will come in handy for small storage.
