Patent ID: 8511520

Claim:
A fluent material dispensing system comprising: a bottle configured for holding the fluent material; a plunger configured for sliding engagement with inner sidewalls of the bottle, the plunger further configured to exert a compressive force on the fluent material when travelling through the bottle interior in a first direction, thereby facilitating expulsion of the fluent material through an outlet of the bottle; and a dispensing mechanism, the dispensing mechanism comprising: a lever operable between a rest position and an engaged position; a plate having a plate aperture, the plate movable between an upper position and a lower position; a rod passing through said plate aperture, the rod operatively coupled to the plunger and extending along the first direction, wherein pivoting motion of the lever from the rest position to the engaged position causes the plate to bind with the rod and move in the first direction from the upper position to the lower position, the plate and the rod thereby causing the plunger to travel in the first direction; and a spring configured to bias the plate to maintain contact with the lever during motion of the lever; a cap for attachment to an end of the bottle opposite the outlet; and a handle attached to the cap, the lever pivotally coupled to the cap, the lever and the handle extending away from the bottle along an axis which is aligned with the first direction and which passes substantially through a center of the bottle, wherein a pivoting return motion of the lever from the engaged position to the rest position causes the plate to at least partially unbind from the rod and move from the lower position to the upper position under bias of said spring and wherein the rod extends along the axis through an aperture formed in the cap, the rod further extending through a gap formed within the lever, the gap located between a hand-actuated portion of the lever and a plate contacting portion of the lever.
