The present invention relates to a reusable dispenser (10) for dispensing a unit dose of a solid product contained in a disposable blister pack (25). The dispenser (10) includes a housing (11), a back plate (30), and a dispensing tray (40). The blister pack (25) containing product is positioned between the housing (11) and the back plate (30), and the product is dispensed through the back plate (30) into the dispensing tray (40) where it can be acquired for use. A puncture tab (35) is integrated into the back plate (30) for aiding in rupturing the backing (28) of the blister pack (25) to dispense the product more easily.
