Carton with gussetted cover panels and a handle

Claim 2

In a carton including a pair of side walls held in spaced apart relation by a pair of end walls at corners of said carton, and a pair of top panels foldably connected to said end walls and foldable toward one another to enclose said carton, the improvement comprising: a plurality of upper gusset panels foldably connected to said top panels and a plurality of lower gusset panels foldably connected to said side walls, said upper and lower gusset panels being joined by a score line extending diagonally from the intersection of a top panel, a side wall, and an end wall; a pair of locking tabs formed at the outer corners of each of said top panels; and said side walls defining slots located at the upper central portions of said side walls for receiving said locking tabs when said top panels are folded toward one another to enclose said carton.

Claim 3

The carton of claim 1, further comprising handle members formed at the ends of said top panels, and wherein said locking tabs are positioned at the opposite sides of said handle members.

Claim 4

The carton of claim 1, wherein the foldable connections between said upper gusset panels and said top panels, and between said side walls and said end walls, define colinear score lines at each corner of said carton prior to said top panels being folded toward one another.

Claim 5

The carton of claim 3, wherein the distance between said colinear score lines, when measured across said end walls, diverges from the bottom of said carton to said locking tabs such that when said top panels are folded toward one another to enclose said carton, said side panels bow outwardly.

Claim 6

The carton of claim 3, wherein said colinear score lines are positioned to allow said carton to collapse to a flat configuration; and further comprising an automatic bottom closure foldably connected to said side and end walls.

Claim 7

The carton of claim 1, wherein said gusset panels urge said top panels upwardly when said top panels are folded to enclose said carton.

Claim 8

The carton of claim 6, wherein said gusset panels urge said top panels upwardly when said top panels are folded to enclose said carton.

Claim 9

The carton of claim 1, wherein said gusset panels urge said side panels outwardly when said top panels are folded to enclose said carton.

Claim 10

The carton of claim 8, further comprising slot projections extending upwardly from the upper edge of each of said side walls, said slot projections defining said slots.

Claim 11

A blank of paperboard or the like for forming a carton, comprising: a first side wall having a top edge, a bottom edge, and a pair of side edges; a first end wall foldably connected along a side edge thereof to a side edge of said first side wall, and having a top edge, a bottom edge, and a free side edge; a second side wall having a top edge, a bottom edge, and a pair of side edges; a second end wall foldably connected along side edges thereof to side edges of both said first and second side walls, and having a top edge and a bottom edge; a lower glue flap foldably connected to a side edge of said second side wall opposite said second end wall; a first top panel foldably connected along a bottom edge thereof to the top edge of said first end wall, and having a top edge and a pair of side edges, one of said first top panel side edges being a free side edge; a second top panel foldably connected along a bottom edge thereof to the top edge of said second end wall, and having a top edge and a pair of side edges; each of said top panels including handle members foldably connected to the top edges of said top panels, said handle members defining locking tabs at opposite ends thereof; a first slot projection extending upwardly from a central portion of said first side wall and defining therein a slot extending from a point below the top edge of said first side wall to a point above the top edge of said first side wall; a second slot projection extending upwardly from a central portion of said second side wall and defining therein a slot extending from a point below the top edge of said second side wall to a point above the top edge of said second side wall; a plurality of lower gusset panels foldably connected to the top edges of said first and second side walls from a position adjacent to said slot projections to the side edges of said side walls; a plurality of upper gusset panels foldably connected along diagonal scores to said lower gusset panels and to the side edges of said second top panel, to the non-free edge of said first top panel, and to an upper glue panel positioned above said lower glue panel; said side edges of said top panels being colinear with corresponding side edges of said end wall; the distance between said colinear edges measured across said end walls diverging from bottom to top; said side edges being positioned to allow said carton to be assembled by adhering said upper and lower glue flaps to said first top panel and first end wall, respectively, such that said assembled carton can be collapsed into a flat configuration; and automatic bottom panels foldably connected to the bottom edges of said side and end walls.

Claim 12

A blank of paperboard or the like for forming a carton, comprising: a first side wall having a top edge, a bottom edge, and a pair of side edges; a first end wall foldably connected along a side edge thereof to a side edge of said first side wall, and having a top edge, a bottom edge, and a free side edge; a second side wall having a top edge, a bottom edge, and a pair of side edges; a second end wall foldably connected along side edges thereof to side edges of both said first and second side walls, and having a top edge and a bottom edge; a lower glue flap foldably connected to a side edge of said second side wall opposite said second end wall; a first top panel foldably connected along a bottom edge thereof to the top edge of said first end wall, and having a top edge and a pair of side edges, one of said first top panel side edges being a free side edge; a second top panel foldably connected along a bottom edge thereof to the top edge of said second end wall, and having a top edge and a pair of side edges; each of said top panels including handle members foldably connected to the top edges of said top panels, said handle members defining locking tabs at opposite ends thereof; a first slot projection extending upwardly from a central portion of said first side wall and defining therein a slot extending from a point below the top edge of said first side wall to a point above the top edge of said first side wall; a second slot projection extending upwardly from a central portion of said second side wall and defining therein a slot extending from a point below the top edge of said second side wall to a point above the top edge of said second side wall; a plurality of lower gusset panels foldably connected to the top edges of said first and second side walls from a position adjacent to said slot projections to the side edges of said side walls; a plurality of upper gusset panels foldably connected along diagonal scores to said lower gusset panels and to the side edges of said second top panel, to the non-free edge of said first top panel, and to an upper glue panel positioned above said lower glue panel; said side edges of said top panels being colinear with corresponding side edges of said end wall; the distance between said colinear edges measured across said end walls diverging from bottom to top; said side edges being positioned to allow said carton to be assembled by adhering said upper and lower glue flaps to said first top panel and first end wall, respectively, such that said assembled carton can be collapsed into a flat configuration; and automatic bottom panels foldably connected to the bottom edges of said side and end walls.
