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 rack that is capable of rotational and translational motion within the slot. The rack has a set of gear teeth that engage with a catch on a plunger. The piston moves in the axial direction to force the pre-whipped topping or icing through the outlet in its packaging. The catch on the piston is locked in one direction and pivots in the opposite direction such that the rack engages with the piston when it moves in a first direction and the rack disengages with the piston when it is moved in a second direction opposite the first direction.

1. A dispenser, comprising: a housing having a cavity defined therein and having an outlet;a piston disposed inside the housing and having at least one retractable catch extending therefrom;at least one gear rack capable of translatory motion, the gear rack having teeth capable of engaging with the catch on the piston such that the piston is moved in a first direction when the rack is moved in the first direction;a trigger in operative relation to the gear rack such that actuation of the trigger causes the rack to move in the first direction; and a cover pivotally attached to the housing at the outlet wherein the cover is mechanically coupled to the gear rack such that opening of the cover causes the gear rack to rotate such that the teeth on the gear rack disengage from the catch on the piston so that the piston can be moved in a second direction for refilling the dispenser. 2. The dispenser of claim 1, further comprising a flexible, cylindrical-shaped bag filled with a paste-like product, the bag sized to match the inner cross-sectional area of the cavity in the dispenser, the bag having an outlet at a first end. 3. The dispenser of claim 1, wherein the outlet of the housing is disposed at a first end, the housing having a second end opposite the first end, the second end having a substantially flat surface for supporting the dispenser on the second end when the dispenser is not in use. 4. The dispenser of claim 1, wherein the outlet of the housing is recessed at the first end, the first end having a substantially planar surface disposed around the outlet for supporting the dispenser on the first end when the dispenser is not in use. 5. The dispenser of claim 1, wherein movement of the gear rack in the second direction opposite the first direction causes the catch to retract such that the piston remains substantially in place when the rack moves in the second direction. 6. The dispenser of claim 1, wherein the trigger is mechanically coupled to the gear rack by a rotating link. 7. A dispenser, comprising: a housing having a cavity defined therein and having an outlet;a piston disposed inside the housing and having at least one retractable catch extending therefrom;at least one gear rack capable of translatory motion, the gear rack having teeth capable of engaging with the catch on the piston such that the piston is moved in a first direction when the rack is moved in the first direction, the gear rack capable of rotating into a position where the catch does not engage with the teeth during movement of the gear rack in the first or a second direction;a trigger in operative relation to the gear rack such that movement of the trigger causes the rack to move in the first direction and release of the trigger causes the rack to move in the second direction opposite the first direction,wherein movement of the gear rack in the second direction causes the catch to retract such that the piston remains substantially in place when the rack moves in the second direction; and a cover pivotally attached to the housing at the outlet wherein the cover is mechanically coupled to the gear rack such that opening of the cover causes the gear rack to rotate such that the teeth on the gear rack disengage from the catch on the piston so that the piston can be moved in the second direction for refilling the dispenser. 8. The dispenser of claim 7, further comprising a flexible, cylindrical-shaped bag filled with a paste-like product, the bag sized to match the inner cross-sectional area of the cavity in the dispenser, the bag having an outlet at a first end. 9. The dispenser of claim 7, wherein the outlet of the housing is disposed at a first end, the housing having a second end opposite the first end, the second end having a substantially flat surface for supporting the dispenser on the second end when the dispenser is not in use. 10. The dispenser of claim 7, wherein the outlet of the housing is recessed at the first end, the first end having a substantially planar surface disposed around the outlet for supporting the dispenser on the first end when the dispenser is not in use. 11. The dispenser of claim 7, wherein the trigger is coupled to the gear rack by at least one pivoting link. 12. A dispenser, comprising: a cylindrical housing having a cavity defined therein and having a first end with outlet and having a second end disposed opposite from the first end, the housing having a longitudinal axis;a piston disposed inside the housing and having at least one retractable catch extending therefrom;at least one gear rack disposed in the cavity and wherein the gear rack moves substantially parallel to the longitudinal axis, the gear rack having a plurality of teeth capable of engaging with the catch on the piston such that the piston is moved in a first direction when the rack is moved in the first direction;a trigger in operative relation to the gear rack such that actuation of the trigger causes the rack to move in the first direction and release of the trigger causes the rack to move in a second direction opposite the first direction;wherein movement of the gear rack in the second direction causes the catch to retract such that the piston remains substantially in place when the rack moves in the second direction;a cover pivotally attached to the housing adjacent to the outlet, the cover having an opening defined therein for receiving a portion of a cartridge containing a viscous flowable material, the cover being mechanically coupled to the gear rack such that opening of the cover causes the gear rack to rotate such that the teeth on the gear rack disengage from the catch on the piston such that the piston can be moved in the second direction relative to the gear rack to the second end of the housing for refilling the dispenser. 13. The dispenser of claim 12, wherein the outlet of the housing is disposed at a first end, the housing having a second end opposite the first end, the second end having a substantially flat surface for supporting the dispenser on the second end when the dispenser is not in use. 14. The dispenser of claim 12, wherein the outlet of the housing is recessed at the first end, the first end having a substantially planar surface disposed around the outlet for supporting the dispenser on the first end when the dispenser is not in use. 15. The dispenser of claim 12, wherein the trigger is coupled to the gear rack by at least one pivoting link. 16. The dispenser of claim 12, wherein the housing further comprises a slot. 17. The dispenser of claim 12, wherein the gear rack is disposed in the slot.
