Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
74 words
A method of filling and adjusting the liquid level in a series of overcapacity flexible containers having differences of capacity from one to another which comprises the steps of: placing a predetermined amount of liquid into a flexible container, altering the shape of said container to cause the level of liquid in said container to rise, and ceasing said altering when the level of the liquid in said container rises to a predetermined position.
Claim 2
Independent Claim
74 words
A method of filling and adjusting the liquid level in a series of overcapacity flexible containers having differences of capacity from one to another which comprises the steps of: placing a predetermined amount of liquid into a flexible container, altering the shape of said container to cause the level of liquid in said container to rise, and ceasing said altering when the level of the liquid in said container rises to a predetermined position.
Claim 3
Dependent Claim
63 words
A method of filling and adjusting the liquid level in a series of overcapacity flexible containers having differences of capacity from one to another as set forth in claim 1 in which the step of altering the shape is accomplished by: flexing said container to reduce the volume of said container and cause the level of said liquid in said container to rise.
Claim 4
Dependent Claim
84 words
A method of filling and adjusting the liquid level in a series of overcapacity flexible containers having differences of capacity from one to another as set forth in claim 1 in which the step of ceasing said altering comprises the steps of: detecting when the level of the liquid in said container rises to a predetermined position in said container, halting said altering of the container shape when the level of the liquid in said container rises to said predetermined position in said container.
Claim 5
Dependent Claim
82 words
A method of filling and adjusting the liquid level in a series of overcapacity flexible containers having differences of capacity from one to another as set forth in claim 3 in which said step of detecting comprises the steps of: applying a liquid level sensing instrument to said container, transmitting liquid level information to a means for halting said altering when the liquid in said container has risen to a predetermined level, and removing said liquid level sensing instrument from said container.
Claim 6
Dependent Claim
52 words
A method of filling and adjusting the liquid level in a series of overcapacity flexible containers having differences of capacity from one to another as set forth in claim 4 which comprises the additional step of: sealing said container whereby after releasing said container said liquid level holds at a uniform level.
Claim 7
Dependent Claim
68 words
A method of filling and adjusting the liquid level in a series of overcapacity flexible containers having differences of capacity from one to another as set forth in claim 5 in which said sealing step comprises the step of: placing a closure upon the opening of said container whereby said closure seals said container and when said container is released the liquid is held at a uniform level.
Claim 8
Dependent Claim
47 words
A method of filling and adjusting the liquid level in a series of overcapacity flexible containers having differences of capacity from one to another as set forth in claim 5 which comprises the additional step of: releasing said container so that said container may assume an equilibrium.
Claim 9
Independent Claim
102 words
A method of filling and adjusting the liquid level in a series of overcapacity flexible containers having differences of capacity from one to another which comprises the steps of: placing a predetermined amount of liquid into a flexible container; moving a part of said container relative to another part so that the level of liquid in said container rises; halting said moving when the level of the liquid in said container rises to a predetermined position; sealing said flexible Container; and, removing any restraints on said moved parts of said container whereby said container is allowed to come into an equilibrium position.
Claim 10
Independent Claim
102 words
A method of filling and adjusting the liquid level in a series of overcapacity flexible containers having differences of capacity from one to another which comprises the steps of: placing a predetermined amount of liquid into a flexible container; moving a part of said container relative to another part so that the level of liquid in said container rises; halting said moving when the level of the liquid in said container rises to a predetermined position; sealing said flexible Container; and, removing any restraints on said moved parts of said container whereby said container is allowed to come into an equilibrium position.
Claim 11
Independent Claim
84 words
A method of filling and adjusting the liquid level in a series of overcapacity flexible containers each having a neck and having differences of capacity from one to another which comprises the steps of: placing a predetermined amount of liquid into a flexible container, flexing said container to reduce the volume of said container and cause the level of said liquid to rise in said container, and halting said flexing when the level of the liquid in said container rises to a predetermined position.
Claim 12
Independent Claim
84 words
A method of filling and adjusting the liquid level in a series of overcapacity flexible containers each having a neck and having differences of capacity from one to another which comprises the steps of: placing a predetermined amount of liquid into a flexible container, flexing said container to reduce the volume of said container and cause the level of said liquid to rise in said container, and halting said flexing when the level of the liquid in said container rises to a predetermined position.
Claim 13
Independent Claim
103 words
A method of filling and adjusting the liquid level in a series of overcapacity flexible containers having differences of capacity from one to another which comprises the steps of: placing a predetermined amount of liquid into said container, flexing said container to cause the level of the liquid in said container to rise, determining the instant when the level of the liquid in said container rises to a predetermined position in said container, halting said flexing at said instant, placing a closure element over the opening to close said opening and freeing said container whereby said flexure is allowed to come into equilibrium.
Claim 14
Independent Claim
103 words
A method of filling and adjusting the liquid level in a series of overcapacity flexible containers having differences of capacity from one to another which comprises the steps of: placing a predetermined amount of liquid into said container, flexing said container to cause the level of the liquid in said container to rise, determining the instant when the level of the liquid in said container rises to a predetermined position in said container, halting said flexing at said instant, placing a closure element over the opening to close said opening and freeing said container whereby said flexure is allowed to come into equilibrium.
