Abstract:
A dispensing device that attaches to a container has: (a) a hollow tube with opposing entrance and exit ends with a connector on the entrance end and a wall defining a flow channel; (b) a sleeve with opposing entrance and exit ends slidably extending over the hollow tube; (c) a sealing gasket between and contacting the hollow tube and sleeve; (d) a trigger mount rigidly attached to the hollow tube or container; (e) a trigger hingedly connected to the trigger mount and operatively connected to the sleeve; (f) an elastic element between the trigger and the hollow tube and/or container; wherein the exit end is closed and there is an opening through the hollow tube wall proximate to the exit end; the sleeve has an open dispensing end, reduces in inside diameter at dispensing end and engages the hollow tube when closed and disengages from the hollow tube when open.

Claim (Index 1):
An article comprising a dispensing device ( 10 ) for attaching to a container ( 100 ) that has a valve stem ( 110 ), the dispensing device comprising:\n (a) a hollow tube ( 20 ) having opposing entrance ( 22 ) and exit ( 24 ) ends, a wall ( 25 ) extending between the entrance and exit ends that defines a flow channel ( 27 ) through the hollow tube and that separates inside the hollow tube from outside the hollow tube with the inside being within the wall of the hollow tube, and a connector ( 26 ) on the entrance end for attaching to a valve stem of the container; (b) a sleeve ( 30 ) extending over a portion of the outside of the hollow tube and capable of sliding over the hollow tube, the sleeve extending over the exit end of the hollow tube and having an entry end ( 32 ) and an opposing dispensing end ( 34 ) with the dispensing end proximate to the exit end of the hollow tube; (c) a sealing gasket ( 40 ) around the outside of the hollow tube between and contacting the wall of the hollow tube and the sleeve, the sealing gasket positioned such that it prevents fluid communication past the sealing gasket outside of the hollow tube between the sleeve and the hollow tube, the seal located between the exit and entrance ends of the hollow tube; (d) a trigger mount ( 50 ) that is part of or that rigidly attaches to the hollow tube; (e) a trigger ( 60 ) hingedly connects to the trigger mount in a first location ( 62 ) with a sleeve portion ( 64 ) of the trigger extending towards the sleeve from the first location and a trigger extension portion ( 66 ) extending on the opposing side of the first location from the sleeve portion, where the sleeve portion operatively engages with the sleeve at a second location ( 68 ) in a manner that causes the sleeve portion to slide the sleeve towards the exit end of the hollow tube when the trigger extension portion is displaced relative to the trigger mount in a direction away from the exit end of the hollow tube when the sleeve is in the closed position; (f) An elastic element ( 70 ) that provides a restorative force to the hollow tube when the trigger extension portion is displaced away from the exit end of the hollow tube; and wherein the exit end of the hollow tube is closed and there is one or more than one hole ( 28 ) extending all the way through the wall of the hollow tube proximate to the exit end; and wherein the sleeve has an open dispensing end and reduces in inside diameter proximate to an the dispensing end such that when the dispensing end of the sleeve slides towards the exit end of the hollow tube to a closed position for the dispensing device, the hollow tube and sleeve engage so as to block fluid flow out from the dispensing end of the sleeve and gasket material ( 40 ) blocks fluid flow between the sleeve and hollow tube yet when the dispensing end moves away from the hollow tube into an open position for the dispensing device the one or more than one hole ( 28 ) is open to allow fluid communication from inside the hollow tube into the sleeve and out from the dispensing end of the hollow tube.
