A cartridge for a hand operated food processor including a blade holder holding at least one blade. A quick release lock is provided for retaining the cartridge in a casing. The cartridge preferably includes at least one series of aligned blades held by the blade holder utilizable for piercing and cutting food. The invention further includes a food processor having a housing including the above cartridge and a casing holding the cartridge. The invention also includes a food processor having a housing that has at least one blade and preferably at least one longitudinal series of blades for piercing and cutting food where each of the blades has side surface portions and a cutting tip edge portion. A base is provided with openings through which the blades can pass to pierce and cut food. The base includes a fixed base portion and a removable base portion. The removable base portion is provided with a sufficient number of longitudinal slots, open at one end of the slots, so that the slots in the removable base portion can be placed over the side surface portions of the blades without encountering the cutting tip edge portions of the blades. The removable base portion can be easily secured to the fixed base portion and easily removed from the fixed base portion utilizing a quick release latch mechanism. The fixed base portion is secured to the housing by a retracting mechanism that permits retraction of the base relative to the housing so that upon retraction the blades extend through the slots to process food in contact with the bottom of the base.

The cartridge of claim 1 wherein the blade holder holds at least one series of aligned blades.3. The cartridge of claim 1 where the blade holder demi-lock is a recess in the blade holder for receiving the casing demi-lock that is in the form of a spring biased latch projection.4. The cartridge of claim 1 wherein the blade holder includes two demi-locks in the form of cam surfaces adapted to mate with two casing demi-locks in the form of locking cams that operate against the cam surfaces to lock the cartridge in the casing.5. The cartridge of claim 1 wherein the cartridge has three parallel series of aligned blades.6. The cartridge of claim 2 wherein the number of blades in each series is at least ten, each of which has a width of from about 1 to about 4 mm and the cartridge is for a meat tenderizer.7. The cartridge of claim 2 wherein the number of blades in each series is less than five, each of which has a width of from about 1 to about 4 cm and the cartridge is for a food chopper.8. The cartridge of claim 3 wherein the cartridge is provided with at least two mirror image recesses so that the cartridge is adapted to be inserted and locked into the casing in a plurality of orientations.9. A food processor having a housing comprising the cartridge of claim 1 and a casing holding the cartridge, said casing having at least one blade holder demi-lock to cooperate with said cartridge demi-lock to together form a quick release lock that securely retains the cartridge in the casing, said cartridge being easily removable from the casing by releasing the quick release lock.10. The food processor of claim 9 wherein the quick release lock comprises at least one spring biased latch projection that protrudes into a recess in the blade holder of the cartridge and the cartridge is released by moving the projection against the spring bias out of the recess to release retention of the cartridge within the casing.11. The food processor of claim 10 wherein the spring biased latch projection is a plastic tab on the casing having a projection biased into the recess in the cartridge by the spring effect of plastic memory of the tab.12. The food processor of claim 10 wherein the spring biased latch projection comprises a projection movable in a groove in the casing and a projection spring biasing the projection toward an end of the groove into the recess in the cartridge.13. The food processor of claim 12 wherein the latch projection is secured through the groove to a control button so that movement of the control button toward the spring moves the latch projection out of the recess to release the cartridge from the casing.14. The food processor of claim 10 where the food processor is a meat tenderizer.15. The food processor of claim 10 where the food processor is a food chopper.
