摘要：
A seal-less, hand-held dispensing device includes a support platform having a pair of finger gripping surfaces first and second hollow members on the platform and a compatibly sized plunger disposed in each hollow member. Each hollow member has a largest inside dimension in the range from about 0.2 mm to about 0.3 mm and each plunger has a largest outside dimension that is sized for compatible receipt within a hollow member. The largest outside dimension of each compatibly sized plunger is from about eighty percent (80%) to about ninety-five percent (95%) of the largest inside dimension of a hollow member. An actuator having a thumb actuating surface thereon is operatively engagable with each plunger. When fully extended a predetermined maximum finger span is defined between the actuating surface and the gripping surfaces, the maximum finger span being not greater than about 150 mm.
