I would create a circuit N2 bottle battery feeding with own manual valve , connected by stiff piping to a PRV (pressure regulated valve) , PRV connected to your end vessel by flexible piping. You will have to have another flushing connection with a manual or pneumatic operated valve (PV) on your vessel , as far as possible from the PRV N2 inlet connection.
If your intent is merely to purge your vessel from ambiant enclosed air and keep a neutral N2 gas above the recipe your are preparing in your vessel , then a very light atmospheric overpressure setting of your PRV is enough to guarantee a good conditioning of your blanketing inside your vessel.
The procedure is to open the PV for a certain amount of time , the PRV will open and , after opening of the manual valve on the N2 bottle battery , the N2 will flow toward your vessel . The enclosed air will then be flushed out of your vessel through the PV opening , and after an amount of time choosen by you , you will command the PV to close. The N2 pressure in your vessel will rise until it reaches the setting of the PRV , and the N2 feeding circuit will then be closed of by this PRV. If your vessel doesn't leak , then your N2 consumption will be minimal , just the amount necessary to flush your vessel and keep it in overpressure. If your vessel is leak proof for the N2 overpressure you want to maintain in your vessel , your problem is solved.
If your vessel does leak hard (e.g. not fully closable) , then I would be very carefull to foresee good room ventilation against suffocation , because your PRV will start to regulate the N2 feeding toward your vessel , in order to keep the demanded overpressure and your PRV will stay open until the whole room is basically brought to the demanded N2 overpressure.

What do you want to cap? Is it metal bottles like for instance deodorant sprays?
Is it is that, one of the manufacturers that I already worked with is Pamasol. I don't know if they also work with other packaging materials like plastic.
