1. A discharge system, comprising:
a discharging device capable of discharging fluid; and a refilling device capable of refilling the discharging device with the fluid, wherein the fluid is suppliable from the refilling device side to the discharging device side by inserting one of a discharge-side coupler provided to the discharging device side and a refill-side coupler provided to the refilling device side into the other to connect the discharging device to the refilling device, and wherein a clearance between the discharge-side coupler and the refill-side coupler that is formed in a connected state of the discharge-side coupler and the refill-side coupler is determined based on a particle size distribution of particulate matters that constitutes the fluid. |
