Abstract
Abstract Apparatus for dispensing liquid including a stopper mounted in a container and a cooperating faucet selectively connected to the stopper. The stopper includes a selectively operated cut-off valve adjacent one end and a resiliently connected flow control valve at the opposite end in opposed relationship with the cutoff valve. The flow control valve operates automatically in accordance with the pressure within the container.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
166 words
Container dispensing apparatus comprising stopper means to be selectively mounted on a container having fluid therein, said stopper means including a body having spaced first and second valve seats, first and second spaced valve members carried by said stopper means, resilient means connecting said first and second valve members and simultaneously urging said first and second valve members in opposite directions, said first valve member being urged by said resilient means toward said first valve seat and normally being in engagement therewith, said second valve member being urged away from said second valve seat by said resilient means, means for maintaining said second valve member in spaced relationship with said second valve seat, means for selectively operating said first valve member, and said second valve member being urged toward said second valve seat by fluid within the container when said first valve member is operated, whereby said second valve member controls the flow of fluid through said stopper means when said first valve member is operated.
Claim 2
Dependent Claim
166 words
Container dispensing apparatus comprising stopper means to be selectively mounted on a container having fluid therein, said stopper means including a body having spaced first and second valve seats, first and second spaced valve members carried by said stopper means, resilient means connecting said first and second valve members and simultaneously urging said first and second valve members in opposite directions, said first valve member being urged by said resilient means toward said first valve seat and normally being in engagement therewith, said second valve member being urged away from said second valve seat by said resilient means, means for maintaining said second valve member in spaced relationship with said second valve seat, means for selectively operating said first valve member, and said second valve member being urged toward said second valve seat by fluid within the container when said first valve member is operated, whereby said second valve member controls the flow of fluid through said stopper means when said first valve member is operated.
Claim 3
Dependent Claim
116 words
The structure of claim 1 in which said means for operating said first valve member includes faucet means selectively mounted on said stopper means, said faucet means having a third valve seat, a valve stem extending through said third valve seat, a third valve member mounted on said valve stem and normally engaging said third valve seat, a portion of said valve stem located adjacent to said first valve member when said stopper means and said faucet means are in assembled relationship, and means for operating said valve stem to move said third valve member out of engagement with said third valve seat and to move said first valve member away from said first valve seat.
Claim 4
Dependent Claim
54 words
The structure of claim 1 in which said resilient means is a spring having a predetermined value, so that a pressure in said container which is greater than the value of said spring moves said second valve member toward said second valve seat to restrict the flow of fluid past said second valve member.
Claim 5
Dependent Claim
164 words
Container dispensing apparatus comprising stopper means selectively mounted on a container, said stopper means including a generally cylindrical hollow body, a sleeve located generally axially of said body, a first valve seat located at one end of said sleeve, a second valve seat located at the opposite end of said sleeve and connecting said sleeve to said body, a first valve member slidably mounted in said sleeve and normally engaging said first valve seat, a second valve member mounted axially of said sleeve, rib means for maintaining said second valve member in spaced relationship with said second valve seat, resilient means connecting said first valve member to said second valve member and urging said valve members in opposite directions, and means for selectively operating said first valve member, whereby fluid under pressure within said container moves said second valve member against the tension of said resilient means to control the quantity of fluid passing between said second valve member and said second valve seat.
Claim 6
Dependent Claim
164 words
Container dispensing apparatus comprising stopper means selectively mounted on a container, said stopper means including a generally cylindrical hollow body, a sleeve located generally axially of said body, a first valve seat located at one end of said sleeve, a second valve seat located at the opposite end of said sleeve and connecting said sleeve to said body, a first valve member slidably mounted in said sleeve and normally engaging said first valve seat, a second valve member mounted axially of said sleeve, rib means for maintaining said second valve member in spaced relationship with said second valve seat, resilient means connecting said first valve member to said second valve member and urging said valve members in opposite directions, and means for selectively operating said first valve member, whereby fluid under pressure within said container moves said second valve member against the tension of said resilient means to control the quantity of fluid passing between said second valve member and said second valve seat.
Claim 7
Dependent Claim
33 words
The structure of claim 4 in which said resilient means is a calibrated spring adapted to apply a predetermined force in opposite directions to said first valve member and said second valve member.
