A Fruit Pitter is disclosed where a plunger and shaft are slidably disposed within a generally cylindrical barrel. The shaft contains a pit engaging end that serves to cut and push a pit through a food item and expel the pit into a pit ejection chamber. The plunger is spring actuated for ease of operation. The food item rests in an opening in the barrel and remains there throughout the pit removal operation until a user removes the food item from the Fruit Pitter. The pit ejection chamber keeps the pit retained until it can be disposed of, and further serves to reduce splattering while the Fruit Pitter is in use.
1. A Fruit Pitter for removing a pit from a food item, the Fruit Pitter comprising:
a generally cylindrical hollow barrel comprising a food receiving aperture and a plunger actuation aperture;
a plunger comprising a plunger body, a plunger head attached to the plunger body, and a pit removal shaft retention structure; the plunger slidably disposed within the generally cylindrical hollow barrel;
a pit removal shaft comprising a pit engaging end, the pit removal shaft attached to the pit removal shaft retention structure of the plunger;
a retention plate affixed within the generally cylindrical hollow barrel, the retention plate comprising a pit removal shaft opening and a spring retention tab;
a spring with the pit removal shaft therethrough where the spring is placed between the plunger and the retention plate to provide return force to the plunger after the plunger has been depressed; and
a pit ejection chamber attached to the generally cylindrical hollow barrel.
2. The Fruit Pitter of claim 1 , wherein the generally cylindrical hollow barrel further comprises a first guide rail and a second guide rail axially disposed adjacent said plunger actuation aperture.
3. The Fruit Pitter of claim 2 , wherein the plunger further comprises a first upper slot and a second upper slot each of which are circumferentially located on the plunger head, the first upper slot slidably engaged with the first guide rail of the generally cylindrical hollow barrel and the second upper slot slidably engaged with the second guide rail of the generally cylindrical hollow barrel.
4. The Fruit Pitter of claim 1 , wherein the generally cylindrical hollow barrel further comprises a transition feature circumferentially disposed within said generally cylindrical hollow barrel.
5. The Fruit Pitter of claim 1 , wherein the plunger further comprises a depression located on the plunger head.
6. The Fruit Pitter of claim 1 , wherein the plunger further comprises a first lower slot and a second lower slot each of which are circumferentially located on the plunger body, the first lower slot slidably engaged with the first guide rail of the generally cylindrical hollow barrel and the second lower slot slidably engaged with the second guide rail of the generally cylindrical hollow barrel.
7. The Fruit Pitter of claim 1 , wherein the plunger further comprises a flex opening on the plunger body to allow the plunger body to deform during assembly.
8. The Fruit Pitter of claim 1 , wherein the plunger further comprises a first flex opening and a second flex opening each of which are located on the plunger body, and a first flange half and a second flange half formed between the first flex opening and the second flex opening.
9. The Fruit Pitter of claim 1 , wherein the plunger further comprises a first flex opening and a second flex opening each of which are located on the plunger body, and a first flange half and a second flange half formed between the first flex opening and the second flex opening, a first lower slot circumferentially located on the first flange half and a second lower slot circumferentially located on the second flange half, the first lower slot slidably engaged with the first guide rail of the generally cylindrical hollow barrel and the second lower slot slidably engaged with the second guide rail of the generally cylindrical hollow barrel.
10. The Fruit Pitter of claim 1 , wherein the spring is retained by both the pit removal shaft retention structure and the spring retention tab of the retention plate.
11. The Fruit Pitter of claim 1 , wherein the retention plate is cylindrical.
12. The Fruit Pitter of claim 1 , wherein the retention plate further comprises a second spring retention tab, a third spring retention tab, and a fourth spring retention tab.
13. The Fruit Pitter of claim 1 , wherein the pit removal shaft opening of the retention plate is generally circular with four radial slots.
14. The Fruit Pitter of claim 1 , wherein the pit engaging end of the pit removal shaft comprises four prongs.
15. The Fruit Pitter of claim 1 , wherein the pit ejection chamber has a concave upper surface to retain a food item.
16. The Fruit Pitter of claim 1 , wherein the pit ejection chamber is made from a generally transparent material.
17. A Fruit Pitter for removing a pit from a food item, the Fruit Pitter comprising:
a hollow barrel having a food receiving aperture and a plunger slidably disposed within the hollow barrel;
a pit removal shaft attached to the plunger wherein the pit removal shaft comprises a pit engaging end;
a spring with the pit removal shaft therethrough to provide return force to the plunger after the plunger has been depressed; and
a pit ejection chamber cylindrically attached under the food receiving aperture of the hollow barrel to receive a pit that has been removed from a food item.
