How to Open the Paint-Can-Style Bottle-In-Can Units from HAZMATPAC:

Some List Labs bacterial toxins are considered Dangerous Goods. These DG’s, as they are called, are packaged with an extra layer of security: HAZMATPAC‘s Bottle-In-Can Unit. This United Nations approved security canister features a patented locking ring for additional closure. Here’s how to open it.


1) Use your hand to grasp the outer edge of the patented locking ring. Pull upwards using light to moderate force. Do not cut the locking ring. There is no need for tools or sharp objects. This step is very easy to perform with your hands.


2) Once the locking ring is removed, we recommend using either a paint can opener or a flat-head screwdriver. To open the canister itself, insert the tip under the outer lip of the lid. Pry upwards using light force.


3) Repeat this prying process clockwise or counterclockwise, according to your comfort, until the lid is fully dislodged from the canister.


4) Dispose of the locking ring and the canister according to appropriate regulations.
