8 Claims. (Cl. 221-148) This invention relates 'to bottle closures for opening 6 and outof the closure member. For sealing the bottle as well as regulating 'the'flow of this purpose acap I is threaded into the upper liquid from the bottle and the invention has for portion of the closure member so that the botits principal object to provide a bottle closure of tom of the cap may be seated and un's'eated on simple and inexpensive construction with which the gasket 8 which surrounds the opening 6, and 5 a bottle may be quickly and easily sealed or the thus provides a seal over' the opening when the flow of liquid from the bottle accurately regulated cap is threaded thereagainst. in dispensing the contents thereof. The. cap I is'provided with an overhanging This and other objects and attendant advanflange 9 andthis flange is extended from the 10 tages of the invention will become more readily periphery by a short lug Ill. The underside 01 10 apparent from the detailed description thereof this lug is grooved and its groove l2 extends inwhich follows, reference being had to the accomwardly of the cap to form the continuation of a panying drawing in which: v 7 vertical groove or duct l3 provided in the pe-v Figure 1. is an enlarged top plan view oi the ripheryof the threaded portion of .the cap. combined bottle closure and liquid dispenser.

A gasket 19 with a central opening 20 is placed against the shoulder to have the neck 2| of a bottle threaded thereagainst to hold the gasket in place and have its central portion overhang the opening in the neck so as to provide a seat around the hole in the gasket.

A bottle cap 22 is threaded into the top of the body member so as to open or close the opening 20 in the gasket and control the flow of the liquid from the bottle to the outlet duct 23 and open the vent thru the duct 24. overhangs the top of the cap, is provided on its under side with an annular groove 25 so as to have the top of the body member engage thereinto and provide an additional seal at the top of the body member when the cap is screwed thereinto.- When the cap is unscrewed and the bottle tilted to dispense some of its liquid the groove 25 keeps any liquid which collects therein from flowing off the overhanging flange except at the outlet groove 28 which is located under the tip 21 of the cap and is in line with the outlet duct for the purpose of directing the liquid as it leaves the bottle.

I claim:

1. In a combined bottle closure and dispenser the combination of an attachable closure member adapted to be fastened to the neck of a bottle or other container and having a restricting discharge opening therein, a cap member movable in the top of said closure member so as to open andclose the restricted discharge opening within the closure member, an overhanging projection at the top of said cap member, an air vent and a liquid outlet duct partiallyextending thru said cap member offset from said discharge opening and a substantially horizontal extension at the end of said outlet duct leading to the edge of the projection at the top of said cap member.

2. In a combined bottle closure and dispenser the combination of an attachable closure member adapted to be fastened to the neck of a bottle or other container and having a restricted discharge opening therethru, a cap member rotatably and endwise movably mounted in the top of said closure member and having an air vent and a liquid outlet duct in the periphery extending axially thereof, a flange on said cap member overhanging said air vent and liquid outlet duct and an extension of said liquid outlet duct leading to the outer edge of said flange on the under side thereof.
