A corrugated cardboard blank for making a collapsible container including one or more panels joined to a bottom panel. The bottom panel is divided into first and second sectional panels on opposing sides of an interface comprising perforated portions extending from a first pair of diagonally opposing corners of the bottom panel. Each perforated portion includes an inner end, wherein the inner ends of the perforated portions are longitudinally spaced from each other. First and second fold lines extend diagonally at least partially between a second pair of diagonally opposing corners of the bottom panel and respective perforated portions. A frangible central portion of the interface extends between the inner ends of the perforated portions, wherein a plurality of unbroken flutes of the corrugated material extend laterally across the central portion of the interface.

A method of collapsing a box from an expanded configuration to a collapsed configuration is disclosed. The method of collapsing a box from an expanded configuration to a collapsed configuration, the box comprising a side panel and a bottom panel attached to the side panel, can comprise bending a center fold line of the side panel; unbending a length fold line defined between the side panel and the bottom panel; bending a first corner fold line that extends from a bottom panel corner of the bottom panel to an edge fold line of a center subpanel of the bottom panel; and bending a second corner fold line that extends from the bottom panel corner to a longitudinal center line that bisects a bottom panel edge of the bottom panel.

Disclosed is a box, a modular box assembly, and a method of assembling a box. The box can comprise a center panel defining a first side, a second side opposite the first side, a first end, and a second end opposite the first end; a first locking panel extending from the first side, the first locking panel comprising a pair of wings, each of the wings defining a locking slot; a second locking panel extending from the second side, the second locking panel comprising a pair of locking tabs, each of the locking tabs engaging a corresponding one of the locking slots; a first side flap panel extending from the first end; and a second side flap panel extending from the second end.

A modular box assembly includes a box having a top end, an opposed bottom end, and side panels extending from the top end to the bottom end. A bottom panel is disposed at the bottom end such that the side panels and the bottom panel define a box cavity and the top end defines a box opening. A shoulder is attached to two side panel and extends inward from the side panels into the box cavity, wherein each shoulder is spaced from the top end a predetermined distance. A box top covers the box opening, the box top being selectively movable about and between a closed position and an open position. In the closed position, the top panel engages the shoulders to support the top panel, and in the closed position an upper surface of the top panel is substantially flush with the top end of the box.

A box comprising: a first pair of opposing side panels; a second pair of opposing side panels connecting the first pair of side panels; a pair of top panels, each top panel joined to one of the side panels of the first pair of opposing side panels; and a handle assembly, the handle assembly comprising: a handle portion, the handle portion attached to one of the pair of top panels, the handle portion comprising a tab at a side end of the handle portion, and a locking panel, the locking panel attached to one of the side panels of the second pair of side panels, the locking panel defining a cut pattern, the cut pattern defining a space therewithin; wherein the space within the cut pattern is configured to receive the tab; and wherein the handle portion is configured to fold from an upright configuration to a folded-down configuration.

A box comprising: a first pair of opposing side panels; a second pair of opposing side panels connecting the first pair of side panels; a pair of top panels, each top panel joined to one of the side panels of the first pair of opposing side panels; and a handle assembly, the handle assembly comprising: a handle portion, the handle portion attached to one of the pair of top panels, the handle portion comprising a tab at a side end of the handle portion, and a locking panel, the locking panel attached to one of the side panels of the second pair of side panels, the locking panel defining a cut pattern, the cut pattern defining a space therewithin; wherein the space within the cut pattern is configured to receive the tab; and wherein the handle portion is configured to fold from an upright configuration to a folded-down configuration.

A basket-type carrier formed from a single blank (1) of foldable sheet material. The carrier (4) comprises a pair of handle panels (10, 60), a pair of bottom panels (20, 70), a pair of bottom reinforcement panels (15, 65), a front panel (30), a back panel (80), side panels (31, 32, 33, 34, 81, 82, 83, 84), side reinforcement panels (21, 22, 71, 72), side flaps (35, 36, 85, 86), interior partition panels (37, 38, 87, 88), and interior partition attachment flaps (39, 89). The carrier is collapsed and expanded by means of an umbrella-type mechanism wherein side flaps (35, 36, 85, 86) connected to side panels (32, 34, 82, 84) and to interior partition panels (37, 87) slide up and down between the handle panels (10, 60). This positions front, back, side, and bottom panels in either the collapsed position with these panels folded against the handle panels, flattening the carrier for storage, or in the expanded position with these panels pulled away from the handle panels, expanding the carrier to receive articles.

A cardboard blank for folding a box has a length and a width, wherein in the length direction five adjacent sections of panels are present, each panel of the first, third and fifth section having a length (H.sub.B) corresponding to the height of the box to be folded, and each panel of the second and forth section having a length (L.sub.B) corresponding to the length of the box to be folded, in the width direction (W) three adjacent rows of panels are present, each panel of the second row having a width (W.sub.B) corresponding to the width of the box to be folded, and each panel of the first and the third row having a width (H.sub.B) corresponding to the height of the box to be folded, between adjacent panels in the length direction (L) crease lines are provided, between panels of the second, the third and the forth section which are adjacent to each other in the width direction (W), crease lines are provided, adjacent panels of the first section are separated from each other by incisions, in the fifth section only a panel in the second row is present, between the panels of the second and the forth section in the first and the third row, a respective joint panel is provided, each of which being divided in triangular sections by crease lines between diagonally opposing corners of the each joint panel, the outer triangle being cut away.

The present invention is directed to a container having increased compression strength. Embodiments of the container comprise a pair of opposing side walls, each of which may include at least one layer of corrugated board having horizontal fluting and at least one layer of corrugated board having vertical fluting. Embodiments of the container also comprise a pair of opposing end walls, each of which may include at least one layer of corrugated board having horizontal fluting and at least one layer of corrugated board having vertical fluting. Embodiments of the container may be prepared from a single blank of corrugated board and may have a bottom surface that is integral with each of the side walls and each of the end walls so as to be considered leak proof. Embodiments of the container may also be configured to be collapsible to a substantially flat arrangement.

A modular box assembly includes a box having a top end, an opposed bottom end, and side panels extending from the top end to the bottom end. A bottom panel is disposed at the bottom end such that the side panels and the bottom panel define a box cavity and the top end defines a box opening. A shoulder is attached to two side panel and extends inward from the side panels into the box cavity, wherein each shoulder is spaced from the top end a predetermined distance. A box top covers the box opening, the box top being selectively movable about and between a closed position and an open position. In the closed position, the top panel engages the shoulders to support the top panel, and in the closed position an upper surface of the top panel is substantially flush with the top end of the box.
