Abstract

A package of one-piece folded construction includes a central, bottom portion having opposite parallel end edges and opposite parallel side edges. Plural end and side portions are attached to the bottom portion and arranged in serial fashion around the bottom portion as follows. A first end portion is attached to and extends laterally of an end edge of the bottom portion; a first side portion attaches to and extends laterally of a side edge of the bottom portion; a second end portion attaches to and extends laterally of another end edge of the bottom portion; and a second side portion attaches to and extends laterally of another side edge of the bottom portion. A gusset portion is provided between adjacent edges of respective ones of the end and side portions so that folding of the gussets orients the end and side portion generally perpendicular to the bottom portion. A first cover member attaches to one of the side portions and a second cover member attaches to the other side portion. The first and second cover members have extensions to overlap when folded generally parallel to the bottom portion. Locking tabs on the cover members and slots for receipt of the tabs when the cover members are folded parallel to the bottom portion are also enclosed.

Claims

1. A blank for making a package of one-piece folded construction, said blank comprising,

a generally central, bottom portion having oppositely arranged generally parallel end edges and oppositely arranged, generally parallel side edges,

plural end and side portions attached to said bottom portion and arranged in serial fashion around said bottom portion as follows,

a first end portion attached to and extending laterally of one of said end edges of said bottom portion,

a first side portion attached to and extending laterally of one of said side edges of said bottom portion,

a second end portion attached to and extending laterally of the other of said end edges of said bottom portion, and

a second side portion attached to and extending laterally of the other of said side edges of said bottom portion,

a plurality of gusset portions extending between adjacent edges of respective ones of said end and side portions so that folding of said gusset portions orients sad end and side portions generally perpendicular to said bottom portion,

first and second cover members respectively attached to either said first and second end portions or said first and second side portions, said second cover member being oppositely arranged relative to said first cover member,

said first and second cover member overlap when folded generally parallel to said bottom portion,

means defining locking tabs on said cover member, and

means on the end or side portions which do not have the cover members attached thereto and defining slots through said send or side portions for receipt of said tabs which project through said slot when said cover members are folded parallel to said bottom portion.

2. The blank of claim 1 wherein said end, said and gusset portions are connected and extend continuously around said bottom portion.

3. The blank of claim 2 including means defining score lines between said end and side portions and said bottom portion, between said gusset portions and respective ones of said end and side portions, and between said cover members and the end or side portions to which they are attached.

4. The blank of claim 3 wherein one of said cover members includes a generally U-shaped opening.

5. The blank of claim 4 wherein said means defining said slots comprise handle portions projecting laterally form the end or side portions to which they are attached so that when said end, side and gusset portions and said cover member are folded on said score lines, said handle portions project above said overlapped cover members.

6. The blank of claim 5 wherein said handle portions have opposite lateral edges and said gusset portions, when folded, extend inwardly of said opposite lateral edges of said handle portions so that when said package and a second package made from an identical blank are placed one atop the other to provide an upper and a lower package, the handles of said lower package nest between the gusset portions of said upper package.

7. The blank of claim 6 wherein said slots are located adjacent to where said handle portions and the end or side portions are attached.

8. A blank for making package of one-piece folded construction, said blank comprising,

a bottom portion having oppositely arranged, generally parallel end edges and oppositely arranged, generally parallel side edges,

plural end portions attached one to each of said bottom portion end edges and extending laterally therefrom,

plural side portions attached one to each of said bottom portion side edges and extending laterally therefrom,

gusset means for orienting said end and side portions generally perpendicular to said bottom portion, extending between adjacent edges of respective ones of said end and side portions

first and second cover members respectively attached to either said end portions or said side portions, said second cover member is oppositely arranged relative to said first cover member,

said first and second cover members overlap when folded generally parallel to said bottom portion,

means defining locking tbs on said cover member, and

means on the end or side portions which do not have the cover portions attached and defining slots through said end or side portions for receipt of said tabs which project through said slot when said cover members are folded parallel to said bottom portion.

9. The blank of claim 8 wherein said end and side portions and gusset means are connected and extend continuously around said bottom portion.

10. The blank of claim 8 wherein one of said cover portions includes a generally U-shaped opening.

11. The blank of claim 8

wherein said means defining said slots comprise handle portions projecting laterally form the end or side portions to which they are attached so that when said end and side portions, said gusset means and said covers members are folded said handle portions project above said overlapped cover members, and

wherein said handle portions have opposite lateral edges and said gusset means, when folded, extend inwardly of said opposite lateral edges of said handle portions so that when said package and a second package made from an identical blank are placed on atop the other, to provide an upper and a lower package, the handles of said lower package nest between the gusset means of said upper package.

12. A package of one-piece folded construction comprising,

a bottom portion having oppositely arranged, generally parallel end edges and oppositely arranged, generally parallel side edges,

plural end and side portions attached to said bottom portion and arranged inertial fashion around said bottom portion as follows,

a first end portion attached to and extending from one of said end edges of said bottom portion,

a first side portion attached to and extending from one of said side edges of said bottom portion,

a second end portion attached to and extending from the other of said end edges of said bottom portion, and

a second side portion attached to and extending from the other of said side edges of said bottom portion,

gusset portions extending between adjacent edges of respective ones of said end and side portions, said gusset portions orient said end and side portions generally perpendicular to said bottom portion,

first and second cover members respectively attached to either said first and second end portions or said first and second side portions, said second cover member is oppositely arranged relative to said first cover member,

said first and second cover members overlap when folded generally parallel to said bottom portion,

mans defining locking tabs on said cover members,

means on the end or side portions which do not have the cover members attached and defining slots for receipt of said tabs when said cover members are folded parallel to said bottom portion,

said means defining said slots includes handle portions projecting above said overlapped cover members, and

said handle portions having opposite lateral edges and said gusset portions extending inwardly of said opposite lateral edges of said handle portions so that when said package and a second package made from an identical blank are placed one atop the other to provide an upper and a lower package, the handles of said lower package nest between the gusset portions of said upper package.
