Abstract
A dispensing device for dispensing a foamable product. The dispensing device comprises a dispensing channel (110; 210; 410). The dispensing channel has: an inlet (111; 211; 411) for communicating with a valve-element (120) of a container (130) containing the foamable product; and an outlet (112; 212; 412) for dispensing the foamable product. The dispensing channel (110; 210; 410) further comprises a variable-volume cavity (140; 240; 440) at the outlet. The variable-volume cavity (140; 240; 440) is defined at least partly by a first component (142; 242; 442) and a second component (144; 244; 444) that is separate from and rigidly movably with respect to the first component to vary the volume of the variable-volume cavity (140; 240; 440) between a first configuration and a second configuration. In the first configuration, the variable-volume cavity (140; 240; 440) has a first volume and the outlet (112; 212; 412) is closed. In the second configuration, the variable-volume cavity has a second volume and the outlet (112; 212; 412) is open. The second volume is greater than the first volume.
