Abstract

A box having two opposed end panels having handholds, two opposed side panels, and a bottom, assembled to form a box having an opening for receiving contents therein, the box including a top panel for closing the opening, the top panel being hingedly connected to a side panel, and including a pair of closure flaps extending from the side of the top panel, the closure flaps positioned to be inserted into the handholds when the top panel is positioned to close the box.

First claim

The invention claimed is:

1. A box having two opposed end panels each having handholds, two opposed side panels, and a bottom, assembled to form a box having an opening for receiving contents therein, the box including a top panel for closing the opening, the top panel being hingedly connected to a side panel, and including a pair of closure flaps extending from lateral sides of the top panel, the closure flaps positioned to be inserted into the handholds when the top panel is positioned to close the box, wherein the bottom of the box is a crash bottom, the crash bottom including an automatic bottom panel which extends from a first side panel selected from the opposed side panels, the automatic bottom panel extending along a first bottom fold line, the automatic bottom panel having an outer edge which is substantially parallel to the first bottom fold line and which is spaced from the first bottom fold line, wherein a first fold line extends from the first bottom fold line to the automatic bottom panel outer edge, and wherein a second fold line extends from the first bottom panel fold line to the bottom panel outer edge, such that the first fold line and the second fold line converge toward one another and terminate at the bottom panel outer edge; and an interior bottom panel which extends from a second side panel selected from the opposed side panels, the interior bottom panel extending along a second bottom fold line, the interior bottom panel having lateral edges generally perpendicular to the second bottom fold line, the lateral edges including tabs that extend beyond the lateral edges.

2. A corrugated paperboard article for assembly into a box, the article comprising:
a first side panel;
a first end panel which extends sidewardly from the first side panel, the first end panel having a handhold;
a second end panel which extends sidewardly from the first side panel spaced from the first end panel, the second end panel having a handhold;
a second side panel extending between and connected to the first end panel and the second end panel;
a first side top panel hingedly attached to the first side panel, the first side top panel including a pair of closure flaps extending from lateral sides of the top panel, the closure flaps positioned to be inserted into the handholds when the top panel is positioned to close the box;
a second side top panel hingedly attached to the second side panel;
an automatic bottom panel which extends from the first side panel along a bottom fold line, the automatic bottom panel having an outer edge which is substantially parallel to the bottom fold line and which is spaced from the bottom fold line, wherein a first fold line extends from the bottom fold line to the automatic bottom panel outer edge, and wherein a second fold line extends from the bottom panel fold line to the bottom panel outer edge, such that the first fold line and the second fold line converge toward one another and terminate at the bottom panel outer edge;
a first end flap which extends from the automatic bottom panel along a first end flap fold line, a first angle being defined between the first end flap fold line and the first fold line, wherein a portion of the first end flap is adhesively connected to the first end panel, to form a multi-ply end wall; and
a second end flap which extends from the automatic bottom panel along a second end flap fold line, a second angle being defined between the second end flap fold line and the second fold line, wherein a diagonal fold line extends along the second end flap, dividing the second end flap into an upper portion which is adhesively connected to the second end panel, and a lower portion below the diagonal fold line which is not connected to the second end panel, wherein parallel sideward displacement of the first side panel with respect to the second side panel causes the article to expand into a box, with the automatic bottom panel being alternatively positioned in a collapsed position alongside and substantially parallel to the side and end panels, and an assembled position substantially perpendicular to the side and end panels, the box further including an interior bottom panel which extends from the second side panel, the interior bottom panel extending along a second bottom fold line, the interior bottom panel having lateral edges generally perpendicular to the second bottom fold line, the lateral edges including tabs that extend beyond the lateral edges.
