the.com/dispenser

A machine devoted to giving you exactly one of something, often with maximum reluctance.

means A device or container designed to release a measured or single portion of something — soap, candy, tape, cash — on demand.

from From the verb 'dispense,' which came through Old French from the Latin 'dispensare,' 'to weigh out or pay out,' a frequentative of 'dispendere,' 'to weigh out' — built from 'dis-' (apart) and 'pendere' (to weigh). The same 'pendere' that gave us 'pension' and 'expense' lurks here: at root, a dispenser is something that carefully weighs out a portion before letting it go.
