Abstract

A device to inject solid materials into foods comprising a piston, a sleeve, and a penetrating tip. Embodiments are described with both segmented and unitary sleeves. Deformation of the tip during storage is minimized by biasing members which withdraw the piston from the tip when an embodiment is not in use. A method is described for flavoring foods with solid objects.

Claims (14)

1. A hand-held device for injecting solid materials into foods comprising:

a hollow sleeve, the sleeve including one or more features connected thereto to permit holding the device in a user's hands;

a penetrating tip on one end of the hollow sleeve;

the penetrating tip having a first closed position and a second open position with the open position allowing materials within the hollow sleeve to exit the hollow sleeve through the tip; and

a piston which longitudinally moves within the hollow sleeve, the piston including a feature connected thereto to permit user operation of the piston by hand;

the piston forcing solid materials within the hollow sleeve to move the penetrating tip into the second open position to enable the solid materials to exit through the penetrating tip;

a biasing member urging movement of the piston away from proximity with the penetrating tip when the piston is positioned within the sleeve to move the penetrating tip into the second open position.

2. The device of claim 1 wherein the sleeve features comprise finger holds projecting outwardly therefrom, and the piston feature comprises a flat end, where together the finger holds and flat end permit user movement of the piston within the sleeve by manual pressure.

3. The device of claim 1 wherein the penetrating tip comprises a segmented conical point.

4. The device of claim 1 wherein the biasing member presses against a conical section within the sleeve.

5. The device of claim 1 wherein the sleeve has two different cross sections.

6. The device of claim 1 wherein the sleeve is divided into at least two separable sections.

7. The device of claim 6 wherein the sleeve may be separably divided without use of tools.

8. The device of claim 6 wherein the separable sections are connected with screw type threads.
