Abstract
A dispensing device having a housing capable of receiving a pre-packaged charge of pre-whipped topping or icing. The housing has an inner wall with a slot formed therein for receiving a rod. The rod engages with a pawl mechanism to move a piston in the axial direction to force the pre-whipped topping or icing through the outlet in its packaging. The pawl engages with the rod when it moves in a first direction and the pawl disengages with the rod when it is moved in a second direction opposite the first direction.
