Claim 7

A carton blank corner construction comprising a plurality of panels including a bottom panel joined to a side panel along a transverse fold line, said transverse fold line intersecting a longitudinal fold line normal thereto, said longitudinal fold line having coincident first and second portions at opposite sides of said point of intersection in part defining said respective side and bottom panels, an end panel joined to said side panel along said longitudinal fold line first portion, said transverse fold line having first and Second portions on opposite sides of said point of intersection with said transverse fold line first portion being common to said side and bottom panels and said transverse fold line second portion in part defining said end panel, said end panel being additionally defined by a first edge extending between ends of said longitudinal and transverse fold line first and second portions respectively which are remote from said point of intersection, a locking panel in part defined by said longitudinal and transverse fold line second portions, said locking panel being additionally defined by a second edge extending between said first edge and said longitudinal fold line second portion at a point thereof remote from said point of intersection, another fold line in said locking panel disposed at an angle of 45* to said transverse fold line second portion and to said longitudinal fold line second portion and setting off therewith a pair of locking panel portions adapted for folding into generally overlapped relationship when said blank is set up to form a generally tubular carton having axially open ends at least one of which is partially closed by said end panel disposed normal to said side panel and second portions of said transverse and longitudinal fold lines.

Claim 8

The carton blank as defined in claim 5 wherein said second edge portion is generally parallel to said longitudinal fold line second portion.

Claim 9

The carton blank as defined in claim 6 wherein said bottom and side panels are additionally defined by edges coincident with said longitudinal fold line.

Claim 10

The carton blank as defined in claim 5 wherein said bottom and side panels are additionally defined by edges coincident with said longitudinal fold line.

Claim 11

A package comprising a plurality of articles housed within a carton, said carton including a body of a generally tubular open ended configuration defined at least in part by top, side, bottom and end panels, said bottom and side panels being disposed generally normal to each other, said end panel being joined to said side panel along a first fold line and to said bottom panel along a second fold line, the improvement comprising means for holding said end panel disposed transverse to said side panel, said holding means being in the form of a locking panel between said bottom and end panels, said locking panel being joined by a portion of said first fold line to said bottom panel, said locking panel being joined by a portion of said second fold line to said end panel, another fold line between said first and second fold line portions setting off a pair of locking panel portions of said locking panel, said locking portions being folded about said another fold line into overlapping relationship to each other inboard of said carton body with said second fold line portion being inboard of said first fold line portion thereby effecting deep projection of at least one of said locking panel portions into said carton body, each said one locking panel portion being held in position by an article seated thereon whereby each one locking panel portion is sandwiched between an article and its associated remaining locking panel portion, and said second fold line portion and said another fold line define therebetween an angle of 45* .

Claim 12

A package comprising a plurality of articles housed within a carton, said carton including a body of a generally tubular open ended configuration defined at least in part by top, side, bottom and end panels, said bottom and side panels being disposed generally normal to each other, said end panel being joined to said side panel along a first fold line and to said bottom panel along a second fold line, the improvement comprising means for holding said end panel disposed transverse to said side panel, said holding means being in the form of a locking panel between said bottom and end panels, said locking panel being joined by a portion of said first fold line to said bottom panel, said locking panel being joined by a portion of said second fold line to said end panel, another fold line between said first and second fold line portions setting off a pair of locking panel portions of said locking panel, said locking portions being folded about said another fold line into overlapping relationship to each other inboard of said carton body with said second fold line portion being inboard of said first fold line portion thereby effecting deep projection of at least one of said locking panel portions into said carton body, each said one locking panel portion being held in position by an article seated thereon whereby each one locking panel portion is sandwiched between an article and its associated remaining locking panel portion, and said second fold line portion and said another fold line define therebetween an angle of 45* .
