Abstract
Abstract Constant motion apparatus for inserting a six sided corrugated liner into carton and thereafter inserting a product into the carton. A corrugated liner is formed and conveyed perpendicularly to a carton conveyor. The liner is thrust from its former to a liner conveyor running parallel to the carton conveyor. From the liner conveyor each liner is pushed into the carton which thereafter receives a product. Means are provided for closing the liner and carton end flaps and sealing the carton end flaps.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
61 words
A method of packaging comprising the steps of, erecting a tubular carton having end flaps, forming a tubular liner having three walls and two partial walls adapted to abut to form a fourth wall, overlapping said partial walls to form a trapezoidal section, longitudinally thrusting said liner into said carton, longitudinally thrusting an article into said liner, and sealing said carton.
Claim 2
Independent Claim
61 words
A method of packaging comprising the steps of, erecting a tubular carton having end flaps, forming a tubular liner having three walls and two partial walls adapted to abut to form a fourth wall, overlapping said partial walls to form a trapezoidal section, longitudinally thrusting said liner into said carton, longitudinally thrusting an article into said liner, and sealing said carton.
Claim 3
Dependent Claim
36 words
A method as in claim 1 further comprising, conveying said carton transversely, conveying said liner longitudinally while erecting said liner, and thereafter conveying said liner both longitudinally and transversely as it is thrust into a carton.
Claim 4
Dependent Claim
24 words
A method as in claim 1 further comprising expanding said trapezoidal section to a rectangular section as said article is thrust into said carton.
Claim 5
Dependent Claim
104 words
Apparatus for lining a carton comprising, an erected carton conveyor traveling in a first direction with tubular cartons oriented transversely of said first direction, a liner former including a conveyor for forming liner blanks into tubes and conveying them in a second direction perpendicular to said first direction with said blanks oriented in a direction transverse to said first direction, a liner conveyor located between said carton conveyor and said liner former and traveling parallel to said carton conveyor, and a liner pusher located adjacent said liner conveyor and including means to push liners from said liner conveyor inTo cartons on said carton conveyor.
Claim 6
Dependent Claim
104 words
Apparatus for lining a carton comprising, an erected carton conveyor traveling in a first direction with tubular cartons oriented transversely of said first direction, a liner former including a conveyor for forming liner blanks into tubes and conveying them in a second direction perpendicular to said first direction with said blanks oriented in a direction transverse to said first direction, a liner conveyor located between said carton conveyor and said liner former and traveling parallel to said carton conveyor, and a liner pusher located adjacent said liner conveyor and including means to push liners from said liner conveyor inTo cartons on said carton conveyor.
Claim 7
Dependent Claim
29 words
Apparatus as in claim 4 further comprising, means on said liner conveyor for compressing each liner into a trapezoidal section configuration prior to its engagement by said liner pusher.
Claim 8
Dependent Claim
65 words
Apparatus as in claim 5 in which said last named means comprises, a trailing L-shaped transport lug having a vertical leg at an acute angle to a horizontal leg, a pivoted leading lug, and means for swinging said leading lug from a position below said horizontal leg to a position above said horizontal leg in which said leading lug engages a wall of the liner.
Claim 9
Dependent Claim
25 words
Apparatus as in claim 6 in which said liner former thrusts said blank between said lugs while said leading lug is below said horizontal leg.
Claim 10
Dependent Claim
42 words
Apparatus as in claim 6 further comprising, means for driving all conveyors in continuous motion, said liner former thrusting said liner between said lugs and with the leading edge of said liner being introduced a substantial distance ahead of said L-shaped lug.
Claim 11
Dependent Claim
32 words
Apparatus as in claim 8 in which the lineal speed of said liner, as it is introduced between said lugs, is approximately three to four times the lineal speed of said lugs.
Claim 12
Dependent Claim
73 words
Apparatus for lining a carton comprising, a constant motion carton conveyor traveling in a first direction, an endless liner conveyor traveling adjacent to and parallel to said carton conveyor, a liner former including an endless conveyor and forming means through which said conveyor carries a liner blank, said liner former transferring formed liners to said liner conveyor, and means for pushing liners from said liner conveyor into said cartons on said carton conveyor.
Claim 13
Dependent Claim
73 words
Apparatus for lining a carton comprising, a constant motion carton conveyor traveling in a first direction, an endless liner conveyor traveling adjacent to and parallel to said carton conveyor, a liner former including an endless conveyor and forming means through which said conveyor carries a liner blank, said liner former transferring formed liners to said liner conveyor, and means for pushing liners from said liner conveyor into said cartons on said carton conveyor.
