Abstract
Abstract A system for improving the adhesion of labels to plastic coated bottles including a series of nozzles discretely aligned to disperse a flame over the outer surfaces of a bottle moving on a conveyor. An inline bottle cooling station is also provided comprising an endless porous belt operating in conjunction with a water spray. The bottles are initially spaced apart a predetermined distance on the conveyor, passed by the flame nozzles, and subsequently cooled with a porous belt and water spray assembly.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
128 words
A system for sensitizing the surfaces of containers comprising: a conveyor for transporting containers through a system; a flame treatment station adjacent said conveyor for heating the container surfaces including a first group of successive upper and lower banks of flame nozzles located along one side of a predetermined length of said conveyor and a second group of corresponding successive upper and lower banks of flame nozzles located on a side of said conveyor opposite said first group with the nozzles of each respective group facing across said conveyor in opposite directions and aligned diagonally with respect to the conveyor centerline; and, a cooling station in line with said conveyor and located downstream from said flame treatment station including means to roll the container against a cooling medium.
Claim 2
Independent Claim
128 words
A system for sensitizing the surfaces of containers comprising: a conveyor for transporting containers through a system; a flame treatment station adjacent said conveyor for heating the container surfaces including a first group of successive upper and lower banks of flame nozzles located along one side of a predetermined length of said conveyor and a second group of corresponding successive upper and lower banks of flame nozzles located on a side of said conveyor opposite said first group with the nozzles of each respective group facing across said conveyor in opposite directions and aligned diagonally with respect to the conveyor centerline; and, a cooling station in line with said conveyor and located downstream from said flame treatment station including means to roll the container against a cooling medium.
Claim 3
Dependent Claim
32 words
The system of claim 1 including a container sequencing means positioned upstream from the flame treatment station for spacing containers a predetermined distance apart prior to entry into said flame treatment station.
Claim 4
Dependent Claim
42 words
The system of claim 1 wherein the flame treatment station includes a series of burners arranged along a predetermined length of said conveyor and aligned to disperse a flame toward the surfaces of a container as it is moved on the conveyor.
Claim 5
Dependent Claim
32 words
The system of claim 3 wherein said burners are arranged into banks of two or more burners, said banks being spaced from each other along the conveyor centerline and aligned diagonally thereto.
Claim 6
Dependent Claim
43 words
The system of claim 4 wherein said banks are mounted on an elongated slotted frame with a threaded shaft pivotly connecting each bank of burners with said frame, said frame being adjustably mounted on stationary horizontal support bars for the lateral adjustment thereof.
Claim 7
Dependent Claim
30 words
The system of claim 1 wherein said conveyor includes a pair of rotate bars positioned on opposite sides thereof and extending at least the length of said flame treatment station.
Claim 8
Dependent Claim
34 words
The system of claim 2 wherein the container sequencing means includes an independently rotatable shaft having a circumferential helical-shaped projection for engaging successive containers and spacing them apart a predetermined distance on said conveyor.
Claim 9
Dependent Claim
52 words
The system of claim 1 wherein said cooling station includes a porous endless belt supported by rollers and a side wall in juxtaposition therewith to form a passageway for the movement of containers, said cooling station further including water applicator means adjacent said belt for maintaining said belt in a moist condition.
Claim 10
Dependent Claim
86 words
The system of claim 8 wherein at least one of said rollers is power driven to cause rotation of said belt thereabout and including spaced apart container support rods positioned about level with and offset from the conveyor, said rollers and belt positioned angularly with respect to the conveyor to deflect a container therefrom onto said rods for movement over the rods a predetermined distance, said cooling station further including means adjacent said rods to apply a cooling medium to the bottom of containers passing thereover.
Claim 11
Independent Claim
69 words
A method of sensitizing the surfaces of a container comprising: positioning a container on a conveyor; conveying said container through a flame treatment station and subjecting said container to a plurality of successive open flames, said flames directed in opposing directions against the container surfaces; and, conveying said container from said flame treatment station to a cooling station, including the step of rolling the container against a cooling medium.
Claim 12
Independent Claim
69 words
A method of sensitizing the surfaces of a container comprising: positioning a container on a conveyor; conveying said container through a flame treatment station and subjecting said container to a plurality of successive open flames, said flames directed in opposing directions against the container surfaces; and, conveying said container from said flame treatment station to a cooling station, including the step of rolling the container against a cooling medium.
Claim 13
Dependent Claim
19 words
The method of claim 10 wherein the container is exposed to said open flames for one to ten seconds.
Claim 14
Dependent Claim
25 words
The method of claim 11 including the step of rotating said container about its longitudinal axis during the time it is exposed to said flames.
Claim 15
Dependent Claim
26 words
The method of claim 10 wherein said cooling medIum is water and including the step of pre-cooling said container prior to contact with said cooling medium.
Claim 16
Dependent Claim
40 words
The method of claim 13 wherein the step of rolling the container against a cooling medium comprises the step of frictionally engaging said container between wet porous surfaces wherein at least one of said surfaces moves relative to the other.
