Abstract

An articulable carton tray apparatus for containment and protection of articles, such as food produce articles, which apparatus may be assembled in a facilitated manner, with reduced amounts of paper materials, while being capable of resisting collapse during stacking and maintaining its assembled configuration under load and stress. The apparatus includes a bottom wall, and side, end and top walls. Flaps emanate from the side, end or top wall to align and lock to one another, remaining ones of the side, end or top walls--to maintain the apparatus in its articulated configuration, through locking means operably positioned within the flap. These locking means engage and co-operate with elements in the adjacent side, end or top wall. Support columns extend between the top walls and the bottom wall to further resist collapse of the apparatus during stacking.

Claims

1. An articulable carton tray apparatus for containment and protection of articles, such as food produce articles, which apparatus resists collapse during stacking while maintaining its assembled configuration under load, said carton tray apparatus comprising:

said bottom wall further defining a plurality of corner regions;

first and second side walls extending along and emanating upwardly from said first second side edges respectively;

first and second end walls extending along and emanating upwardly from said first and second end edges, respectively;

first and second top walls extending along and emanating from said first and second end walls, respectively;

said bottom wall, said first and second side walls, and said first and second end walls, upon articulation of same, describing an article containment region;

said first and second top walls, extending, upon articulation, substantially parallel to said bottom wall to partially cover said article containment region;

flap means operably emanating from at least one of said first and second side walls, said first and second end walls, and said first and second top walls, for operable alignment with an adjacent respective one of said first and second side walls, said first and second end walls, and said first and second top walls,

said flap means including a peripheral portion and an internal portion;

first locking means for maintaining said articulation of said bottom wall, said first and second side walls, said first and second end walls, and said first and second top walls,

said first locking means including at least one first locking member positioned within and operably emanating from said internal portion of said flap means for operable positive engagement with said adjacent respective one of said first and second side walls, said first and second end walls, and said first and second top walls; and

support column means, operably positioned, upon articulation, in a support position between at least one of said first and second top walls, and said bottom wall, for resisting collapse of said carton apparatus during stacking.

2. The articulable carton tray apparatus according to claim 1 wherein the invention further comprises:

second locking means for maintaining said support column means in said support position between said at least one of said first and second top walls, and said bottom wall.

3. The invention according to claim 2 wherein said first locking means and said second locking means, upon articulation of said bottom wall, said first and second side walls, said first and second end walls, and said first and second top walls, are substantially aligned relative to one another for simultaneous deployment of same into their respective articulated locking positions.

4. The invention according to claim 1 wherein said first locking means comprises:

means for releaseably retaining said first locking member, upon articulation, operably engaged with said adjacent respective one of said first and second side walls, said first and second end walls, and said first and second top walls.

5. The invention according to claim 2 wherein said second locking means comprises:

at least one second locking member operably emanating from one of said first and second side walls, said first and second end walls, and said first and second top walls, for positive locking engagement with said support column means for maintaining same in said support position.

6. The invention according to claim 5 wherein said support column means for resisting collapse of said carton apparatus during stacking further comprises:

at least one support column member operably positioned, upon articulation, in a support position between and substantially perpendicular to said bottom wall and said at least one of said first and second top walls, and transversely spanning at least a portion of at least one of said plurality of corner regions defined by said bottom wall.

7. The invention according to claim 6 wherein said support column means further comprises:

at least one intermediate web member operably emanating from said flap means, joined thereto along a common edge;

a fold line extending along said common edge between said flap means and said at least one intermediate web member;

said at least one support column member corresponding to and emanating from said at least one intermediate web member, joined thereto along a common edge; and

a fold line extending along said common edge between said at least one support column member and said at least one intermediate web member.

8. The invention according to claim 6 wherein said support column means further comprises:

at least one intermediate web member operably emanating from at least one end edge of at least one of said first and second side walls, joined thereto along a common edge;

a folding line extending along said common edge between said at least one end edge and said at least one intermediate web member;

said at least one support column member corresponding to and emanating from said at least one intermediate web member, joined thereto along a common edge; and

a fold line extending along said common edge between said at least one support column member and said at least one intermediate web member.

9. The invention according to claim 1 wherein said articulable carton tray apparatus further comprises:

stacking tab means for facilitating alignment of one of said carton tray apparatuses relative to another one of said carton tray apparatuses during the aligned stacking of same,

said stacking tab means including a plurality of stacking tab members operably emanating upwardly in opposed pairs, from at least one pair of said first and second side wall means, a pair of said first and second end wall means, a pair of said flap means and adjacent ones of said support column means to said pair of said flap means.

10. The invention according to claim 9 wherein said stacking tab means further comprises:

a plurality of primary stacking tab members emanating upwardly in opposed pairs from said pairs of said first and second side walls and first and second end walls; and

a plurality of secondary stacking tab members emanating upwardly in opposed pairs from one of said pairs of said flap means, and said pairs of said support column means,

said secondary stacking tab members being operably aligned with and cooperating with adjacent ones of said primary stacking tab members upon said articulation of said bottom wall, said first and second side walls, said first and second end walls, said first and second top walls, and said flap means.

11. The invention according to claim 1 wherein said bottom wall, said first and second side walls, said first and second end walls, and first and second top walls are formed from a single integrated piece of carton material.

12. The invention according to claim 11 wherein said first and second side walls are joined to said bottom wall along common edges therebetween located at said first and second sides respectively and are articulable into substantially perpendicular relation to said bottom wall along fold lines operably located along said common edges between said first and second sides walls and said bottom wall.
