Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
169 words
The method of forming a fiberboard container having a reinforcing fiberboard liner, which method comprises providing a rectangular liner blank having a pair of opposed side vertical edges and having a pair of horizontal edges, the liner blank being centrally cut along a line parallel to the horizontal edges, which cut extends to locations adjacent to but spaced apart a predetermined distance from both of the opposed side vertical edges, the liner providing a pair of side panel-end panel reinforcements lying, respectively, above and below the horizontal cut, folding the liner blank along said horizontal cut to dispose the reinforcement pairs in overlying relationship to each other, affixing one exterior surface of the folded liner to a side panel and an end panel of an outer container blank having four interconnected panels which constitute the four upstanding sidewalls of the completed container, and folding the remaining outer container side and end panels over the liner and affixing these two panels to the other exterior surface of said folded liner.
Claim 2
Independent Claim
169 words
The method of forming a fiberboard container having a reinforcing fiberboard liner, which method comprises providing a rectangular liner blank having a pair of opposed side vertical edges and having a pair of horizontal edges, the liner blank being centrally cut along a line parallel to the horizontal edges, which cut extends to locations adjacent to but spaced apart a predetermined distance from both of the opposed side vertical edges, the liner providing a pair of side panel-end panel reinforcements lying, respectively, above and below the horizontal cut, folding the liner blank along said horizontal cut to dispose the reinforcement pairs in overlying relationship to each other, affixing one exterior surface of the folded liner to a side panel and an end panel of an outer container blank having four interconnected panels which constitute the four upstanding sidewalls of the completed container, and folding the remaining outer container side and end panels over the liner and affixing these two panels to the other exterior surface of said folded liner.
Claim 3
Dependent Claim
22 words
The method of claim 1 wherein said folded liner is adhesively affixed to the central two panels of the outer container blank.
Claim 4
Dependent Claim
40 words
The method of claim 1 wherein the outer container blank includes a glue flap for forming a manufacturer''s joint and wherein an adhesive pattern is applied to said four panels and to the glue flap of the outer container blank.
Claim 5
Dependent Claim
161 words
A fiberboard blank adapted to form an inner liner for a reinforced container when mated with an outer container having opposed side panels and end panels, said blank being rectangular and having two opposed side vertical edges of a length of approximately double the desired height of the reinforcement and two parallel horizontal edges, said blank also having a horizontal cut extending generally between said two opposed side vertical edges which cut is parallel to said horizontal edges, said cut dividing said blank into two halves and each of said halves containing a vertical line of weakness dividing said half into a side panel reinforcement and an end panel reinforcement, said horizontal cut terminating a predetermined short distance from each of said two opposed side vertical edges to provide attaching means in said terminal regions, said attaching means joining said halves during the fabrication of the container but being adapted to be torn when the reinforced container is opened for use.
Claim 6
Dependent Claim
161 words
A fiberboard blank adapted to form an inner liner for a reinforced container when mated with an outer container having opposed side panels and end panels, said blank being rectangular and having two opposed side vertical edges of a length of approximately double the desired height of the reinforcement and two parallel horizontal edges, said blank also having a horizontal cut extending generally between said two opposed side vertical edges which cut is parallel to said horizontal edges, said cut dividing said blank into two halves and each of said halves containing a vertical line of weakness dividing said half into a side panel reinforcement and an end panel reinforcement, said horizontal cut terminating a predetermined short distance from each of said two opposed side vertical edges to provide attaching means in said terminal regions, said attaching means joining said halves during the fabrication of the container but being adapted to be torn when the reinforced container is opened for use.
Claim 7
Dependent Claim
37 words
The blank of claim 4 wherein said attaching means is provided by short score lines extending from the ends of said cut to each of said opposed side edges, said score lines being colinear with said cut.
Claim 8
Dependent Claim
16 words
The blank of claim 4 wherein said predetermined distance is not greater than about 1 inch.
Claim 9
Dependent Claim
121 words
A reinforced container which is fabricated to include the blank defined in claim 4, which reinforced container comprises an outer container blank providing opposed side panels and end panels, said reinforcement blank being folded about said horizontal cut to constitute upper and lower overlying halves, means adhesively joining the side panel reinforcement and the end panel reinforcement of said lower half to the interior surface of adjacent side and end panels of said outer container blank, means adhesively joining the side panel reinforcement and the end panel reinforcement of said upper half to the interior surface of the remaining side panel and end panel of said outer container blank, and joint means connecting said outer container blank in flattened tubular configuration.
Claim 10
Dependent Claim
28 words
The reinforced container of claim 7 wherein said lower half of said reinforcement blank is attached to the central side and end panels of said outer container blank.
Claim 11
Dependent Claim
40 words
The reinforced container in accordance with claim 8 wherein both said reinforcement blank and said outer container blank are formed of corrugated fiberboard, the flutes of said corrugated fiberboard extending horizontally in one blank and vertically in the other blank.
Claim 12
Dependent Claim
45 words
The reinforced container in accordance with claim 7 wherein said outer blank includes upper and lower closure flaps attached respectively to each of said side and end panels and includes a glue flap hinged to a panel at one lateral edge of said outer blank.
