Listerine Pump for one handed person and elderly [SEP] I usually buy a different mouthwash  (Scope) but can't find a pump designed for it. I have to buy Listerine 1.5 Liter. Since my daughter was injured (broke her metacarpal bone from dodgeball), I have to find a way that will make it easy for her to pour mouthwash in a cup. Especially if someone's arm/hand is in a cast. This is helpful also for elderly, especially those with arthritis.
