Shipping carton

Claim 2

A regular hexahedron shipping carton formed by six panels having recloseable means for access to said carton by at least one of said panels, comprising: (a) four panels forming the regular hexahedron with open sides, at least one of said four panels having one unattached end forming an access panel; (b) two side panels for closing the open sides; and (c) means integral with each side panel at the perimeter thereof for engaging the adjacent surfaces of said four panels, said engaging means including tucking means for frictionally and releasably securing said access panel and for permitting opening and reclosing said access panel without disassembly of said carton, said engaging and tucking means being the sole means necessary for securing said access panel in closed position.

Claim 3

The shipping carton as in claim 1 wherein said engaging means integral with each side panel comprises: (a) a flap foldably attached to each edge of said side panel, each flap having a pair of opposed ends, said flaps being folded 90° to the side panel and respectively adjacent to one of said four panels, the adjacent ends of the flaps forming a common edge; and (b) tab means foldably attached to selected ones of said opposed ends for restraining said flaps in the folded position.

Claim 4

The shipping carton of claim 2 wherein said tab means includes elongated tabs on the corresponding end of said flaps adjacent the flaps contiguous with the access panel and said tucking means comprises extension means on said flaps contiguous with the access panel for folding over the elongated tabs and for sandwiching the extension means between the elongated tabs and the access panel.

Claim 5

The shipping carton as in claim 3 also including triangular flap means formed at each end of said extension means for relieving resistance to the sandwiching of said extension means between the elongated tabs and the access panel and to the removal of said extension means from between said elongated tabs and said access panel.

Claim 6

The shipping carton as in claim 1 also including means for securing said two side panels to at least two of said four panels for enclosing the open sides of the said hexahedron and leaving free said access panel.

Claim 7

A blank for forming a regular hexahedron shipping carton having a means for access to said carton through at least one side of said carton, comprising: (a) a rectangular sleeve blank laterally sectioned into four panels forming the top, back, bottom and front panels of said carton, at least one of said panels having one unconnected end edge; and (b) a pair of side cover blanks, each comprising: (1) a rectangular side panel substantially coextensive with the area defined by the side edges of said sleeve blank when folded to form said regular hexahedron carton, said side panel having a pair of opposed end edges and a pair of opposed side edges; (2) a pair of rectangular end flaps, each having a middle section and a pair of tabs, one of said tabs being foldably attached to each end of said middle section, said middle section of each end flap having a length substantially equal to one end edge of said side panel and the middle section of each one of said pair of end flaps being foldably attached on a fold line to an individual one of said end edges; (3) a pair of rectangular side flaps each having a length substantially equal to one side edge of said side panel and one of said pair of side flaps being foldably attached on a fold line to an individual one of said side edges; and (4) an extension flap foldably attached at one side edge on a fold line to the side remote from said side panel of at least one of said side flaps and having a length substantially equal to said side flap.

Claim 8

A blank for forming a regular hexahedron shipping carton having a means for access to said carton through at least one side of said carton, comprising: (a) a rectangular sleeve blank laterally sectioned into four panels forming the top, back, bottom and front panels of said carton, at least one of said panels having one unconnected end edge; and (b) a pair of side cover blanks, each comprising: (1) a rectangular side panel substantially coextensive with the area defined by the side edges of said sleeve blank when folded to form said regular hexahedron carton, said side panel having a pair of opposed end edges and a pair of opposed side edges; (2) a pair of rectangular end flaps, each having a middle section and a pair of tabs, one of said tabs being foldably attached to each end of said middle section, said middle section of each end flap having a length substantially equal to one end edge of said side panel and the middle section of each one of said pair of end flaps being foldably attached on a fold line to an individual one of said end edges; (3) a pair of rectangular side flaps each having a length substantially equal to one side edge of said side panel and one of said pair of side flaps being foldably attached on a fold line to an individual one of said side edges; and (4) an extension flap foldably attached at one side edge on a fold line to the side remote from said side panel of at least one of said side flaps and having a length substantially equal to said side flap.

Claim 9

The blank as in claim 6 also including a triangular flap formed in each end of each extension flap by a fold line.

Claim 10

The blank as in claim 6 wherein said sleeve blank is divided by fold lines into top, back, bottom and front panels in longitudinal series and wherein said front panel and said top panel each has one unconnected end edge.

Claim 11

The blank as in claim 8 also including a dust flap foldably attached on a fold line to the unconnected end edge of said top panel.

Claim 12

The blank as in claim 6 wherein said sleeve blank is in two pieces, each piece being foldably divided into two panels, one forming the top and back panels of the carton and the other forming the bottom and front panels of the carton, and wherein each of said panels has one unconnected end edge.

Claim 13

The blank as in clam 10 also including a dust flap foldably attached on a fold line to the unconnected end edge of each of said top and bottom panels.

Claim 14

The blank as in clam 10 also including a dust flap foldably attached on a fold line to the unconnected end edge of each of said top and bottom panels.

Claim 15

The blank as in claim 10 wherein each side flap also includes an extension flap attached thereto.
