Abstract
A collapsible box can include a top panel; a front panel hingedly attached to the top panel; a first side panel hingedly attached to the top panel and the front panel; a second side panel hingedly attached to the top panel and the front panel; a rear panel hingedly attached to the top panel, the first side panel, and the second side panel; and a bottom panel hingedly attached to the front panel, the rear panel, the first side panel, and the second side panel; and wherein the front panel defines a frame portion and a lower flap portion connected together by a front line of weakness; wherein the frame portion is coupled to the first side panel, the second side panel, and the bottom panel; and wherein the lower flap portion is coupled to the top panel.
Claims22
A collapsible box defining an inner cavity and comprising:
- a top panel;
- a front panel hingedly attached to the top panel;
- a first side panel hingedly attached to the top panel and the front panel;
- a second side panel hingedly attached to the top panel and the front panel;
- a rear panel hingedly attached to the top panel, the first side panel, and the second side panel;
- a bottom panel hingedly attached to the front panel, the rear panel, the first side panel, and the second side panel;
- and
- an access flap configured to provide access to the inner cavity through the front panel and the top panel when the access flap is folded back about a top hinge defined by the top panel;
- wherein:
- the front panel defines a frame portion and a lower flap portion connected together by a front line of weakness;
- the frame portion is coupled to the first side panel, the second side panel, and the bottom panel;
- and
- the lower flap portion is coupled to the top panel.
A blank comprising:
- a front panel defining a lower flap portion and a frame portion coupled together by a front line of weakness;
- a first top subpanel coupled to the lower flap portion by a front hinge;
- a second top subpanel that tapers away from the first top subpanel;
- a side panel coupled to the second top subpanel and defining a first side and a second side opposite from the first side, the first side coupled to the frame portion by a first side hinge;
- and
- a rear panel coupled to the second side by a second side hinge, the second side hinge being parallel to the first side hinge and perpendicular to the front hinge;
- wherein:
- a lateral hinge extends at least partially across the front panel, the side panel, and the rear panel;
- and
- the lateral hinge is parallel to the front hinge.
A blank comprising:
- a front panel defining a lower flap portion and a frame portion coupled together by a front line of weakness;
- a top subpanel coupled to the lower flap portion by a front hinge;
- a side panel coupled to the frame portion;
- and
- a rear panel coupled to the side panel;
- wherein a first lateral hinge and a second lateral hinge both extend at least partially across the front panel, the side panel, and the rear panel, and the first lateral hinge is parallel to the second lateral hinge;
- wherein the rear panel:
- defines a plurality of V-shaped fold lines configured to fold from a planar shape to a truncated pyramidal shape;
- and
- the plurality of V-shaped fold lines of the rear panel intersect at least one of the first lateral hinge and the second lateral hinge.
A collapsible box and comprising:
- a top panel;
- a front panel hingedly attached to the top panel;
- a first side panel hingedly attached to the top panel and the front panel;
- a second side panel hingedly attached to the top panel and the front panel;
- a rear panel hingedly attached to the top panel, the first side panel, and the second side panel, the rear panel being configured to fold from a planar shape to a truncated pyramidal shape when the collapsible box is collapsed;
- and
- a bottom panel hingedly attached to the front panel, the rear panel, the first side panel, and the second side panel;
- wherein:
- the front panel defines a frame portion and a lower flap portion connected together by a front line of weakness;
- the rear panel defines a plurality of V-shaped fold lines;
- the frame portion is coupled to the first side panel, the second side panel, and the bottom panel;
- and
- the lower flap portion is coupled to the top panel.
A collapsible box and comprising:
- a top panel comprising a first top subpanel coupled to a second top subpanel;
- a front panel hingedly attached to the top panel;
- a first side panel hingedly attached to the top panel and the front panel;
- a second side panel hingedly attached to the top panel and the front panel;
- a rear panel hingedly attached to the top panel, the first side panel, and the second side panel;
- and
- a bottom panel hingedly attached to the front panel, the rear panel, the first side panel, and the second side panel;
- wherein:
- a lateral hinge is defined extending at least partially across the front panel, the first side panel, the second side panel, and the rear panel;
- the lateral hinge is configured to collapse the collapsible box when a user presses inwards on the first side panel and the second side panel along the lateral hinge;
- the front panel defines a frame portion and a lower flap portion connected together by a front line of weakness;
- the frame portion is coupled to the first side panel, the second side panel, and the bottom panel;
- the lower flap portion is coupled to the first top subpanel by a front hinge and is coupled to the top panel;
- the first top subpanel defines a top hinge between the front hinge and the second top subpanel;
- a portion of the first top subpanel positioned between the top hinge and the front hinge defines an upper flap portion;
- and
- an access flap of the collapsible box comprises the upper flap portion and the lower flap portion.
