Abstract
A dispensing device (10) capable of dispensing both frothed and non-frothed liquids, the dispensing device having in order a fluid transport medium (20) defining a flow channel (25), a trigger controlled liquid flow regulator (30) defining a flow channel (35) through which fluid may flow when the trigger (37) is in one position but not when the trigger is in another position, a flow block (50) defining a flow channel (55) in fluid communication with a gas channel (65) and removably attached to the flow regulator, a flow restriction orifice (40) between the flow block and the flow regulator (30), a mixing block (70) defining a flow channel (75) containing mixing elements and optionally stabilization (80) and extension blocks each containing a flow channel (85) wherein each flow channel is in fluid communication with one another.
