Abstract:
A granular applicator comprising:a dispersion reservoir including a wall, a first open end, a second open end, and an inner surface; a primary reservoir capable of holding a quantity of granular material, said primary reservoir attached to said dispersion reservoir and penetrating the wall of said dispersion reservoir to thereby feed the granular material to said dispersion reservoir; and a manual air pump configured for pulsing pneumatic waves of air through the first open end of said dispersion reservoir to carry the granular material in said dispersion reservoir through the second open end of said dispersion reservoir; a one-way valve disposed within the first open end of said dispersion reservoir, said one-way valve permitting air passage into said dispersion reservoir through the first open end and precluding substantially all materials from exiting said dispersion reservoir through the first open end, said one-way valve comprising: a valve seat having an outer circumference and a perforated interior, the outer circumference of said valve seat is integral with or affixed to the inner surface of said dispersion reservoir proximate the first open end of said dispersion reservoir in a substantially air-tight manner; and a stopper having a stopper disk and a retaining tab, the stopper disk covers the perforated interior of said valve seat, and the retaining tab penetrates the interior of said valve seat biasing the stopper disk against said valve seat, thereby precluding substantially all materials from exiting said dispersion reservoir through the first open end.
