Abstract
Abstract Apparatus for filling containers, such as bottles, which has a liquid filling pipe for insertion into the container to near the bottom thereof and a seal for sealing the pipe to the container. Gas is supplied to the inside of the container, and when a predetermined pressure is reached inside the container, liquid flow commences into the container through the fill pipe. Gas is released from the container in a first lower rate when liquid flow is initiated and, thereafter, when the lower end of the fill pipe is immersed in the liquid, the release of gas from the container takes place at an increased rate thereby providing for rapid filling of the container.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
262 words
An apparatus for filling containers, such as bottles, with liquid and comprising; a filling pipe adapted for insertion into the container from above to dispose the lower end of the pipe near the bottom of the container, a liquid supply chamber, means connecting said supply chamber to the upper end of said pipe, a chamber for gas under pressure, a gas relief chamber, a seal surrounding said pipe and adapted for sealingly engaging the mouth of a container when the pipe is inserted into the container, a first valve connected between said pressure gas chamber and the container side of said seal to communicate the gas pressure chamber with the container when the mouth of the container is engaged by said seal, a gas return passage leading from the lower end of said pipe upwardly and including a lateral opening near the top of the container, a main conduit connecting the upper end of said passage with said relief chamber and having a first flow restrictor therein, a check valve in said main conduit between said passage and said first restrictor, which opens away from said first flow restrictor, said check valve being normally open and closing in response to liquid flowing from the passage into said main conduit, a second valve connected in parallel with said first flow restrictor and having a second flow restrictor in series therewith, and a third valve connected between the side of said first valve which is remote from said gas pressure chamber and said main conduit between said check valve and said first flow restrictor.
Claim 2
Independent Claim
262 words
An apparatus for filling containers, such as bottles, with liquid and comprising; a filling pipe adapted for insertion into the container from above to dispose the lower end of the pipe near the bottom of the container, a liquid supply chamber, means connecting said supply chamber to the upper end of said pipe, a chamber for gas under pressure, a gas relief chamber, a seal surrounding said pipe and adapted for sealingly engaging the mouth of a container when the pipe is inserted into the container, a first valve connected between said pressure gas chamber and the container side of said seal to communicate the gas pressure chamber with the container when the mouth of the container is engaged by said seal, a gas return passage leading from the lower end of said pipe upwardly and including a lateral opening near the top of the container, a main conduit connecting the upper end of said passage with said relief chamber and having a first flow restrictor therein, a check valve in said main conduit between said passage and said first restrictor, which opens away from said first flow restrictor, said check valve being normally open and closing in response to liquid flowing from the passage into said main conduit, a second valve connected in parallel with said first flow restrictor and having a second flow restrictor in series therewith, and a third valve connected between the side of said first valve which is remote from said gas pressure chamber and said main conduit between said check valve and said first flow restrictor.
Claim 3
Independent Claim
262 words
An apparatus for filling containers, such as bottles, with liquid and comprising; a filling pipe adapted for insertion into the container from above to dispose the lower end of the pipe near the bottom of the container, a liquid supply chamber, means connecting said supply chamber to the upper end of said pipe, a chamber for gas under pressure, a gas relief chamber, a seal surrounding said pipe and adapted for sealingly engaging the mouth of a container when the pipe is inserted into the container, a first valve connected between said pressure gas chamber and the container side of said seal to communicate the gas pressure chamber with the container when the mouth of the container is engaged by said seal, a gas return passage leading from the lower end of said pipe upwardly and including a lateral opening near the top of the container, a main conduit connecting the upper end of said passage with said relief chamber and having a first flow restrictor therein, a check valve in said main conduit between said passage and said first restrictor, which opens away from said first flow restrictor, said check valve being normally open and closing in response to liquid flowing from the passage into said main conduit, a second valve connected in parallel with said first flow restrictor and having a second flow restrictor in series therewith, and a third valve connected between the side of said first valve which is remote from said gas pressure chamber and said main conduit between said check valve and said first flow restrictor.
Claim 4
Independent Claim
262 words
An apparatus for filling containers, such as bottles, with liquid and comprising; a filling pipe adapted for insertion into the container from above to dispose the lower end of the pipe near the bottom of the container, a liquid supply chamber, means connecting said supply chamber to the upper end of said pipe, a chamber for gas under pressure, a gas relief chamber, a seal surrounding said pipe and adapted for sealingly engaging the mouth of a container when the pipe is inserted into the container, a first valve connected between said pressure gas chamber and the container side of said seal to communicate the gas pressure chamber with the container when the mouth of the container is engaged by said seal, a gas return passage leading from the lower end of said pipe upwardly and including a lateral opening near the top of the container, a main conduit connecting the upper end of said passage with said relief chamber and having a first flow restrictor therein, a check valve in said main conduit between said passage and said first restrictor, which opens away from said first flow restrictor, said check valve being normally open and closing in response to liquid flowing from the passage into said main conduit, a second valve connected in parallel with said first flow restrictor and having a second flow restrictor in series therewith, and a third valve connected between the side of said first valve which is remote from said gas pressure chamber and said main conduit between said check valve and said first flow restrictor.
Claim 5
Dependent Claim
28 words
An apparatus according to claim 1 in which said first flow restrictor has a flow passage therethrough smaller in effective area than that through said second flow restrictor.
Claim 6
Dependent Claim
25 words
An apparatus according to claim 1 in which said first, second, and third valves form a structural unit within which said valves are serially arranged.
Claim 7
Dependent Claim
22 words
An apparatus according to claim 1 in which said first, second, and third valves are adapted for being opened and closed selectively.
Claim 8
Dependent Claim
54 words
An apparatus according to claim 1 in which said means connecting said liquid supply chamber with said pipe comprises a liquid passage having a valve therein which is open when the container is supplied with gas under pressure from said gas pressure chamber and which closes in the absence of pressure in said container.
Claim 9
Dependent Claim
123 words
In combination with a counter-pressure bottle filling machine; a liquid fill pipe adapted to be inserted into a bottle through the mouth thereof to a point near the bottom of the bottle, seal means to seal the inserted pipe to the mouth of the bottle, means for supplying gas under pressure tHrough said seal means to the bottle, means for supplying liquid to the bottle via said pipe, a main conduit leading from the bottle through said seal means, a first flow restrictor connecting said main conduit to the atmosphere, a second flow restrictor offering less resistance to fluid flow than said first restrictor and connected between said main conduit and the atmosphere, and an on-off valve in series with said second restrictor.
