Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 196 words
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.
Claim 2
Dependent Claim 196 words
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.
Claim 3
Dependent Claim 21 words
The device of claim 1 wherein means (22) carried by said housing are provided to vary said predetermined period of time.
Claim 4
Dependent Claim 30 words
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.
Claim 5
Dependent Claim 71 words
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.
