Abstract

An erectable container apparatus constructed from a substantially square blank of material for use in releasably storing various articles therewithin. The apparatus includes a plurality of side panels each having an inner edge attached to a base portion, an outer edge attached to a corresponding top flap member, and a left and right edge. The left and right edges are operably positioned at acute angles relative to the respective inner edges to which they intersect so as to provide substantially upright and inwardly sloping side panels upon articulation of the erectable container apparatus toward and into its fully articulated orientation. Locking elements are operably associated with at least two of the top flap members for releasably locking the erectable container apparatus in a fully erected orientation, as well as to releasably maintain the top flap members and the inwardly sloping side panels in a base and article covering orientation.

Claims

1. An erectable container apparatus constructed from a substantially square blank of material for use in releasably storing various articles therewithin, said erectable container apparatus comprising:

base means for providing an underlying support to one or more of the various articles to be releasably stored within said erectable container apparatus,

said base means having a top surface, a bottom surface opposite said top surface and at least three peripheral edges;

side panel means for operably restraining the position of said articles within said container apparatus, said side panel means having an inner edge operably attached to at least a portion of a corresponding one of each of said at least three peripheral edges of said base means, as well as an outer edge substantially parallel to said inner edge, and a left and right edge operably positioned between said inner and outer edges of each of said side panel means,

each of said left and right edges of said side panel means being operably positioned at an acute angle relative to said inner edge to which they operably intersect, for providing substantially upright and inwardly sloping side panels after said erectable container apparatus has been articulated into a fully erected orientation;

a plurality of top flap means for operably covering at least a portion of said base means and said articles, at least one of said plurality of top flap means having a proximal end operably attached to a corresponding one of said outer edges of said side panel means, a distal end, and a first and second side end, wherein said first and second side ends are operably positioned between said proximal end and said distal end of said corresponding one of said plurality of top flap means,

said first and second side ends of said at least one of said plurality of top flap means being operably positioned at an acute angle relative to said corresponding one of said outer edge of said side panel means,

at least a portion of said plurality of said top flap means and said side panel means collectively serving to substantially cover said top surface of said base means and said articles when said erectable container apparatus has been articulated into said fully erected orientation; and

locking means operably associated with at least two of said plurality of top flap means for locking, and, alternatively releasing said erectable container apparatus into and from said fully erected orientation respectively.

2. The erectable container apparatus according to claim 1 wherein the invention further comprises at least one web means each operably attached to said right edge of one of said side panel means and to said left edge of another adjacently positioned one of said side panel means,

each of said at least one web means being folded inwardly toward said base means upon said articulation of said erectable container apparatus so as to substantially preclude gapping between adjacently positioned ones of said side panel means after said erectable container apparatus has been articulated into said fully erected orientation.

3. The invention according to claim 2 wherein each of said at least one web means includes an apex operably positioned adjacent a portion of said base means and a back edge distally spaced from said apex;

said web means further including direction folding means operably and substantially positioned between said apex and said back edge for facilitating said inward folding of said web means upon said articulation of said erectable container apparatus toward and into said fully erected orientation.

4. The invention according to claim 2 wherein each of said at least one web means have a triangular configuration.

5. The invention according to claim 1 wherein said locking means comprises tab means integrally formed in a portion of one or more of said plurality of top flap means, and, tab receiving means integrally formed in a portion of at least another of said plurality of top flap means,

at least a portion of said tab means in said one top flap means being releasably engageable within said tab receiving means in said another top flap means so as to releasably maintain each of said plurality of top flap means and each of said side panel means in a base covering orientation, as well as to lock, and alternatively release, said erectable container apparatus into and from its said fully erected orientation respectively.

6. The invention according to claim 5 wherein said tab means is integrally formed at said distal end of said one of said plurality of top flap means, and, said tab receiving means being integrally formed adjacent said distal end of an opposing one of said plurality of top flap means.

7. The invention according to claim 1 wherein said locking means comprises flap engagement means operably formed in at least two of said plurality of top flap means for releasably engaging a portion of each of said at least two of said plurality of flap means, to, in turn, releasably maintain each of said plurality of top flap means and each of said side panel means in a base covering orientation, as well as to lock, and alternatively release, said erectable container apparatus into and from its said fully erected orientation respectively.

8. The invention according to claim 7 wherein:

said base means include four peripheral edges, said side panel means comprises four of said side panel means and said plurality of top flap means comprises four flaps;

said flap engagement means being operably formed in each of said four flaps.

9. The invention according to claim 8 wherein said flap engagement means comprises a slit in each of said four flaps, wherein a first two of said slits are operably positioned in two adjacently positioned ones of said four flaps respectively, for engageable cooperation with each other, and a second two of said slits are operably positioned in the remaining two other adjacently positioned flaps respectively, for engageable cooperation with each other.

10. The invention according to claim 1 wherein each of said plurality of top flap means have a substantially pentagonal configuration,

each of said first and second side ends including a lower side edge and an upper side edge meeting at an obtuse angle.

11. The invention according to claim 1 wherein each of said plurality of top flap means have a substantially triangular configuration,

each of said first and second side ends including a lower side edge and an upper side edge which are co-linear.

12. The invention according to claim 1 wherein said erectable container apparatus is constructed from paperboard material.

13. The invention according to claim 1 wherein the erectable container apparatus is constructed from a single blank of material.

14. The invention according to claim 1 wherein said locking means are integrally formed in at least two of said plurality of top flap means.
