Abstract
A liquid dispenser for dispensing a predetermined volume of liquid to a surface includes a bottle for containing a supply of the liquid with a movable sleeve coaxially located with and receiving the outlet end of the bottle. The sleeve includes a valve which closes and opens the bottle outlet as the sleeve moves toward and away, respectively, from the bottle outlet. The sleeve also includes a metered liquid reservoir to the opposite side of the seal from the bottle outlet for receiving a predetermined measured amount of liquid from the bottle. A valve is located at the reservoir to control the flow of liquid from the reservoir, and a dauber tip is in liquid-flow communication with the reservoir for receiving liquid from the reservoir and dispensing the liquid on a surface.
Claims17
A liquid dispenser comprising:
- a bottle for containing a supply of liquid to be dispensed;
- means defining an outlet for the liquid at one end of the bottle;
- a sleeve having a longitudinal axis coaxially located with the central axis of the outlet defining means of the bottle and receiving therein the outlet defining means of the bottle, and selectively movable along the coaxis of the bottle outlet defining means and the sleeve in both directions;
- first valve means associated with the sleeve for closing the liquid outlet of the bottle when the sleeve has moved in a first direction along the coaxis, and for opening the liquid outlet of the bottle when the sleeve has moved in a second direction along the coaxis;
- biasing means for biasing the sleeve in the first direction closing the liquid outlet of the bottle;
- means defining a metered liquid reservoir in the sleeve for receiving liquid from the bottle when the sleeve is moved in the second direction causing the first valve means to open the liquid outlet of the bottle;
- a porous dauber tip in liquid-flow communication with the reservoir for receiving liquid therefrom;
- and,
- second valve means in the path of liquid communication between the reservoir and dauber tip operable between an open position and a closed position for controlling the flow of liquid from the reservoir to the dauber tip.
