Increase the pressure of the gas inside
Helium is helium. Storing it is difficult as it diffuses through many substances.
The hydrogen in such a reaction can effectively be collected using an apparatus called the gas jar. THis can be done by fitting the reaction flask with cork and a delivery tube running from the reaction flask to the gas jar. As the reaction proceed, the hydrogen evolved will be collected in the gas jar.
Glass lids are slid under the gas jar when gases are being collecting. This is so the water vapor is collected.
It has nowhere to evaporate to. Evaporation is dispersion of molecules.

Theoretically, they could expel gas into a sealed container like a jar and ship that.

Yes it's a gas, and if it is 'air' then it's a mixture of nitrogen, oxygen, argon and tiny amounts of other gasses.
I sealed the pickle jar after I took out a pickle.
A sealed jar with a large candle inside a small jar would not last 5 minutes. A large jar with a small candle most likely would last 5 minutes
This depends on the volume and pressure of gas.
Yes
How long can one keep a sealed jar of 'foie gras' in the fridge?
If the jar is still sealed, it is probably safe. But I'd be more concerned that the flavor and texture would still be good. I'd just get a new jar.
If you try it you will probably be in the bath room or hospital.So don't do it.
