Claim 2

A gable-top four-sided container formed of an integral blank comprising four hingedly connected side panels wherein each of two opposed side panels are extended above the hinged connections accommodating within the side panel extension a lock tab opening and wherein each of the unextended opposed side panels have hingedly connected thereto the shorter of the parallel sides of a trapezoidal top closure panel said trapezoidal top closure panel forming a gable with the opposing top closure panel; a grip panel hingedly attached to the longer parallel side of said top closure panel, said grip panel containing a grip slot and, at opposing lateral edges, a lobed lock tab which cooperates with a lock tab opening in the adjacent extended side panel to fasten the container top panels forming an outward flexing gable; a bottom panel hingedly connected to each side panel interlocking with the other bottom panels forming a weight supporting bottom; and an end tab hingedly attached to one of the side panels and extending the longitudinal length of said side panel with said end tab attached to another side panel, aligned with the side panel to form a four-sided container.

Claim 3

The gable-top container of claim 1 wherein said extended length of said opposed side panels is of triangular shape with the base of the triangle corresponding to the width of the side panel.

Claim 4

The gabled-top container of claim 2 wherein the lock tab opening is circular.

Claim 5

The gable-top container of claim 1 wherein said container is made collapsible by each of a pair of opposed bottom panels having inclined edges provided with hinged attaching flaps, the attaching flaps being secured to the underside of the bottom panel, next adjacent to said attaching flap whereby the bottom members are automatically swung from a collapsed to an erected position.

Claim 6

The gable-top container of claim 4 wherein said bottom panels contain an attaching flap having extending on the inclined edge a lobe which forms a notch at its conjunction with an attaching flap whereby the bottom panels are locked in an erected position.

Claim 7

The gable top container of claiM 1 wherein said extended side panels contain a score line which extends from said lock tab opening to a position between said hinged connections.

Claim 8

The gable-topped carton of claim 1 made of a material which can be formed into a flexible sheet which sheet can be cut and scored to form a blank adapted to be folded into a self supporting container.

Claim 9

A blank formed from a single sheet of material adapted to be folded into a self-supporting box comprising: a. a first side comprising a panel having a bottom panel attached to one end along a transverse scored hinge line and at the other end an extension provided with a cutout portion centered on the longitudinal center line of the panel; b. a second side comprising a panel attached to said first side panel along a longitudinal scored hinged line, a top panel attached to one end of said second side panel along a transverse scored hinge line and a bottom panel attached to the opposite end of said second side panel along a transverse scored hinge line, said top panel comprising a trapezoidal section joined to the side panel along a transverse scored hinge line which is the shorter parallel side of the trapezoid and joined along the longer parallel side of the trapezoid by a transverse scored hinge line to a section containing a cutout portion and having lobed tabs on its two lateral edges said tabs extending outwardly of a line which is an extension of each of the nonparallel sides of the trapezoidal section, said nonparallel sides of length sufficient to permit alignment of the lobed tab with the longitudinal center line of the adjacent side; c. a third side which matches (a), attached to said second side panel along a longitudinal scored hinge line; d. a fourth side which matches (b) attached to said third side panel along a longitudinal scored hinge line; and e. an end tab attached by a longitudinal scored hinge line along the edge length of a side (d) which is not attached to another side.

Claim 10

A blank formed from a single sheet of material adapted to be folded into a self-supporting box comprising: a. a first side comprising a panel having a bottom panel attached to one end along a transverse scored hinge line and at the other end an extension provided with a cutout portion centered on the longitudinal center line of the panel; b. a second side comprising a panel attached to said first side panel along a longitudinal scored hinged line, a top panel attached to one end of said second side panel along a transverse scored hinge line and a bottom panel attached to the opposite end of said second side panel along a transverse scored hinge line, said top panel comprising a trapezoidal section joined to the side panel along a transverse scored hinge line which is the shorter parallel side of the trapezoid and joined along the longer parallel side of the trapezoid by a transverse scored hinge line to a section containing a cutout portion and having lobed tabs on its two lateral edges said tabs extending outwardly of a line which is an extension of each of the nonparallel sides of the trapezoidal section, said nonparallel sides of length sufficient to permit alignment of the lobed tab with the longitudinal center line of the adjacent side; c. a third side which matches (a), attached to said second side panel along a longitudinal scored hinge line; d. a fourth side which matches (b) attached to said third side panel along a longitudinal scored hinge line; and e. an end tab attached by a longitudinal scored hinge line along the edge length of a side (d) which is not attached to another side.

Claim 11

The blank of claim 8 wherein said first side and third side panels each contain a score line extending from said cutout portion along the center line of the panel to a position sufficiently removed from said cutout portion to permit conformation of the side panel extension to the lobed tabs of the top panel.
