ABSTRACT:
A hand pressure operated seed planter includes an elongated vertically disposed tubular body for storing seeds with a cup-shaped telescoping bottom cap having seed dispensing openings. A rotatably mounted closure plate is mounted within the bottom cap. The bottom cap is normally forced downwardly by a spring. A spiral plate that is adapted to function as a helical cam member is operatively associated between the storage tube and the closure plate to rotate the closure plate to an open position allowing seeds to fall through the dispensing hole when enough downward pressure is applied to the planter to force the bottom cap upwardly upon the tubular body.
