A large canning jar or welding rod case should also work. I just tie my bear spray to the steps with a couple Titan Straps. A bit of silicone tape on the steps makes the can "stick" to it better.
This is a very interesting and intelligent article on the pro's and con's of pepper spray in regards to bears:
https://craigmedred.news/2017/06/29/bea ... yes-or-no/One of the more interesting parts in the article to me was how bad we are at appraising risk. The chance of a bear attack, even in heavy bear country, is so fantastically small that to worry about it at all is basically wasted energy that should be spent addressing more realistic dangers. But we're evolutionarily hard wired to be inordinately afraid of teeth and claws, so we cary a four-pound handgun strapped to us while getting in and out of a float plane...vastly increasing the very substantial risk of drowning to mitigate the exceptionally small risk of animal attack.
Historically I've needed wasp spray a hundred times more than I've needed bear spray or a gun, but I don't cary it. Not sure why...
The Pelican cases I’m familiar with have a vent that can be closed prior to flight, then opened upon arrival. They work fine for containment. We also used them for aerial transport of some very wicked capture drugs that you would not want to be exposed to......insurance in the event of an accident.
In addition to the closeable vent, the Pelican cases come filled with foam. Make a cutout in the foam for the can of spray and the foam itself should prevent any leakage.

That style of Pelican case (screw vent) hasn't been made for a decade or more. They now come with a self-venting pressure release valve that's not adjustable.
Pelican cases are amazing, but the design of the pelican case has always been to keep dirt and moisture
out, not to hold pressure
in. Even with the old-style screw valve to which you refer, the case will burp pressure through the lid O-ring at fairly low psi. That's why you don't see Pelican cases looking like pregnant pillows. They'll suck down and hold a fantastic amount of negative pressure, but they don't puff up. The valve was only there to keep the case from vacuum locking. There's a reason that compressed air canisters are round, not square.
A Pelican case will probably contain a small leak, but if the OC canister bursts, a Pelican case is not the right receptacle to contain it. As for the cut-out foam containing the OC...I wouldn't bet on it. It's open cell and air travels thought in with little impediment.
All that said, I have cans of bear spray that are twenty years old. I don't cary them...they're sitting in the nursery. But it's not like they routinely self destruct with slight changes in temperature or pressure.
For those exposed to OC...while it's fantastically painful, it's important to remember that virtually no physical damage is being done. It feels like white-hot gravel is getting ground into your eyes and Draino is going down your throat and you can't breath, but if you force yourself to open your eyes, you CAN see, and if you force yourself to breath then you WILL get oxygen. I wouldn't want to try to land with a face full of the stuff, but it's not nerve gas. If you can get past the pain and concentrate, you can actually function fairly well.
