Portable liquid metering device

Abstract

A portable liquid metering device for detachably securing to the opening of a liquid container and adapted to discharge a predetermined volume of liquid upon tipping and having a register for counting and displaying the number of times the bottle is tipped.

I claim: 
     
       1. A self-contained portable liquid metering and dispensing device comprising: a housing (10) having upper pouring means (10a) and lower inlet means (19) for detachably securing .Iadd.the housing .Iaddend.to the opening of a liquid container; air means (16) extending through said housing into said lower means (19); conduit means connecting said pouring and lower means and including a flexible resilient portion (13), means (12a) for pinching off flow in said resilient portion (13), a reverse polarity motor means (11) connected to and actuating said pinching means (12a); power means (20) for actuating said motor means (11); .[.movable magnet means (24b) moved by tipping of the device; switch means (24) actuated by said magnet means (24g).].; .Iadd.switch means (24) actuable by tipping of the device; .Iaddend.logic means (100) actuated by said switch means (24) to cause said motor means to rotate to release said pinching means (12a) from said resilient portion (13), stop rotation for a predetermined period of time and then rotate on reverse to pinch off said resilient portion (13); and means (17) for counting and displaying the number of actuations of said switch means (24); all of said means being carried completely by said housing. 
     
     
       2. The device of claim 1 wherein means (22) carried by said housing are provided to vary said predetermined period of time. 
     
     
       3. The device of claim 1 wherein means (18) carried by said housing are provided to count and display the number of times the device is removed from the liquid container. 
     
     
       4. The device of claim 1, 2 .[.or 3.]., .Iadd.3 or 5 .Iaddend.wherein display is not visible except when user passes a magnet over a magnetic reed switch means (23) carried by said housing and connected to said logic means (100). .Iadd. 5. The device of claim 1 wherein movable magnet means (24b) is provided which is moved by tipping of the device so as to actuate said switch means (24). .Iaddend.
