Dispersion system and vehicle having the same

A dispersion system for a vehicle having at least one door opening and an interior space, the system comprising:

• at least two tank modules including a reservoir for storing a medium to be dispersed, each tank module being configured to fit through the door opening;
• a door configured to fit into one of the at least one door opening and comprising a through hole;
• and
• a dispersion unit having a dispersion channel in fluid communication with the reservoir of the at least two tank modules and the through hole of the door, characterized in that
• each tank module further comprises:
• an outlet channel in fluid communication with the dispersion channel;
• and
• a closure closing the reservoir with respect to the outlet channel in a fluid tight manner, wherein in each of the each tank modules, the closure is arranged between the reservoir and the outlet channel, wherein the closure comprises an elastic flap covering an opening of the outlet channel, and
• a controller configured to individually open the closure of each tank module,
• wherein the elastic flap is flat and seals the reservoir with respect to the outlet channel when the closure is in a closed position, and is bulgy when the closure moves from the closed position towards an open position, or
• wherein the elastic flap, when the closure moves from the closed position towards an open position, bulges to such an extent that the flap moves into the outlet channel, so that moving the closure from the closed position to the open position forms the bulgy flap, or, both.
