Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 121 words
A method for making fluid-filled containers comprising: holding two part-containers of plastic material in respective holders comprising respectively an anvil and a welding horn; positioning the holders and thereby the part-containers with respective corresponding surfaces thereon disposed adjacent one another and defining a gap therebetween; feeding fluid into the container through a part of the gap which extends around a major part of the periphery of the container; exhausting fluid in the container through a minor part of the length of the gap during said feeding step; closing the gap; and uniting the surfaces to complete the container by applying ultrasonic vibrations to the welding horn acting against the anvil through the material of the corresponding surface of the part containers.
Claim 2
Independent Claim 121 words
A method for making fluid-filled containers comprising: holding two part-containers of plastic material in respective holders comprising respectively an anvil and a welding horn; positioning the holders and thereby the part-containers with respective corresponding surfaces thereon disposed adjacent one another and defining a gap therebetween; feeding fluid into the container through a part of the gap which extends around a major part of the periphery of the container; exhausting fluid in the container through a minor part of the length of the gap during said feeding step; closing the gap; and uniting the surfaces to complete the container by applying ultrasonic vibrations to the welding horn acting against the anvil through the material of the corresponding surface of the part containers.
Claim 3
Dependent Claim 25 words
A method as set forth in claim 1 wherein a remnant of the fluid remains disposed between said surfaces while the same are being united.
Claim 4
Dependent Claim 15 words
A method as set forth in claim 1 wherein the fluid is a carbonated beverage.
Claim 5
Dependent Claim 26 words
A method as set forth in claim 2 wherein a pressurized fluid is disposed on either side of said surfaces while the same are being united.
Claim 6
Dependent Claim 46 words
A method as set forth in claim 1 wherein said fluid feeding step comprises feeding a purging fluid into the container through the gap to drive out air and thereafter feeding the fluid to be finally contained into the chamber to drive out the purging fluid.
Claim 7
Dependent Claim 20 words
A method as set forth in claim 1 wherein the part-containers comprise container halves having annular flanges presenting said surfaces.
Claim 8
Dependent Claim 26 words
A method as set forth in claim 1 wherein is included the step of fitting one or more relatively rigid reinforcing sleeves over the completed container.
Claim 9
Dependent Claim 51 words
A method as set forth in claim 1 wherein is included the steps of providing the part-containers as a nested stack of frusto-conical cups, taking individual cups from the stack for forming into containers and filling, and internally pressurized the cups to change the same from frusto-conical shape to cylindrical shape.
Claim 10
Dependent Claim 131 words
A machine for making containers and filling the same with fluid comprising: a fluid source; a pair of holders for holding respective part-containers, one of said holders comprising an anvil and the other comprising a welding horn; means for moving said holders and part-containers held thereby into closely spaced relative relationship with a gap therebetween and into a position adjacent said fluid source; a non-return valve extending around said gap for introducing fluid from said source into the interior of the part-containers held by the holders through said gap therebetween; means for moving the holders to bring the part-containers into contact with one another; and an ultrasonic transducer for imparting ultrasonic vibrations to the welding horn toward the anvil for sealing contacting portions of the part-containers together to complete the container.
Claim 11
Dependent Claim 131 words
A machine for making containers and filling the same with fluid comprising: a fluid source; a pair of holders for holding respective part-containers, one of said holders comprising an anvil and the other comprising a welding horn; means for moving said holders and part-containers held thereby into closely spaced relative relationship with a gap therebetween and into a position adjacent said fluid source; a non-return valve extending around said gap for introducing fluid from said source into the interior of the part-containers held by the holders through said gap therebetween; means for moving the holders to bring the part-containers into contact with one another; and an ultrasonic transducer for imparting ultrasonic vibrations to the welding horn toward the anvil for sealing contacting portions of the part-containers together to complete the container.
Claim 12
Dependent Claim 30 words
A machine as set forth in claim 9 wherein said fluid source includes an annular chamber disposed in surrounding relationship to the gap when the holders are in said position.
Claim 13
Dependent Claim 31 words
A machine as set forth in claim 9 wherein is included sealing means disposed between the fluid source and each of the holders when the latter are disposed in said position.
Claim 14
Dependent Claim 23 words
A machine as set forth in claim 9 wherein is included a valve-controlled exhaust chamber for receiving fluid driven from the container interior.
Claim 15
Dependent Claim 46 words
A machine as set forth in claim 9 wherein said source includes means for containing a supply of purging fLuid and means for containing a supply of filling fluid, there being included means for connecting the two supply containing means alternatively to the fluid introducing means.
Claim 16
Dependent Claim 36 words
A machine as set forth in claim 13 wherein said connecting means comprises a double acting piston and a cylinder therefor, the opposite ends of the cylinder being connected respectively to the two supply containing means.
Claim 17
Dependent Claim 22 words
A machine as set forth in claim 9 wherein is included a sleeving station having means for fitting sleeves over completed containers.
