Abstract

The present invention is a reclosable carton in the form of a rectangular box, having opposed parallel substantially single layer front and rear walls, opposed parallel substantially single layer side walls and a closed bottom end forming a carton body. The carton includes a top end flip-top reclosable hood. The hood includes a hood skirt and is formed by an outside main hood panel foldably connected to the carton body, an inside hood panel foldably and severably connected to the front carton wall and including a transverse fold line defining a front hood skirt panel, and two minor hood forming flaps foldably and severably connected to the carton side walls and foldably connected to the inside hood panel. The transverse fold line extends collinearly across the side panels and the carton is provided with an opening tear strip extending completely across the hood forming panels and flaps and parallel to the transverse fold line. The invention provides a friction group of panels to enhance the frictional engagement between the hood and the carton body to ensure that the hood remains closed after it is opened and reclosed, yet prevents the outermost fold score lines associated with the skirt from expanding outwardly and rupturing.

Claims

1. A carton comprising:

front and rear walls, said front and rear walls each having a top edge;

a bottom wall;

opposed side walls extending between and connected with said front and rear walls; and

a top wall structure including a reclosable hood pivoted along an axis along the top edge of said rear wall, said reclosable hood comprising;

an outer hood panel foldably connected to the rear wall;

a friction panel group being connected to said front and side walls;

a hood skirt foldably and releasably connected to said friction panel group, said friction panel group underlying said hood skirt and releasably connected thereto along a removable tear strip, said friction panel group being fixedly connected to said front and side walls; and

an inside hood panel foldably connected to the hood skirt and underlying the outer hood panel.

2. The carton according to claim 1, including two innermost corners at the connection between each said side wall and the front wall, said corners underlying said friction group and including a stripped out area.

3. The carton according to claim 2, wherein said tear strip includes at least one tab means for overlying at least part of said stripped out area, said tab means extending toward said bottom wall of said carton.

4. The carton according to claim 2, said friction panel group including two middle corners overlying said stripped out areas and including a plurality of parallel fold score lines, said lines being generally parallel to said connection between said each side wall and the front wall and forming an inside fold score region.

5. The carton according to claim 4, said inside fold score region being narrower than said stripped out area.

6. A carton blank comprising:

a generally central portion including a plurality of foldably connected carton body forming panels and having a first end and a second end;

a bottom forming panel group foldably connected to said first end;

a hood forming panel group foldably connected to said second end and including an outside hood panel foldably connected to said central portion at a first score line, a friction panel group foldably connected to said central portion along a second score line collinear with said first score line, a skirt panel group releasably connected to said friction panel group along a removable tear strip parallel to said second score line, and a hood top wall forming panel group foldably connected to said skirt panel group along a score line parallel to said tear strip.

7. The blank according to claim 6, said cuts and scores comprising a plurality of score lines for forming said foldable connections, at least a portion of said score lines adapted to be overlaid, including an overlying score area comprising a plurality of parallel cut lines and an underlying stripped out area score wider than said overlying score area, said underlying stripped out area and overlying score area being aligned with and under at least part of one of said score lines.

8. A carton comprising:

front and rear walls, said front and rear walls each having a top edge;

a bottom walls;

opposed side walls extending between and connected with said front and rear walls; and

a top wall structure including a reclosable hood pivoted along an axis along the top edge of said rear wall, said reclosable hood comprising;

an outer hood panel foldably connected to the rear wall;

a hood skirt connected to said outer hood panel;

a friction panel group connected to said front and side walls and foldably and releasably connected to said hood skirt, said friction panel group underlying and substantially coextensive with said hood skirt; and

an inside hood panel foldably connected to the hood skirt and underlying the outer hood panel.

9. The carton according to claim 8, wherein said friction panel group and said hood skirt extend substantially continuously and coextensively about said front and side walls.

10. The carton according to claim 9, wherein said friction panel group is releasably connected to said hood skirt along a removably tear strip, said friction panel group being fixedly connected to said front and side walls.

11. The carton according to claim 10, including two innermost corners at the connection between each said side wall and the front wall, said corners underlying said friction group and including a stripped out area.
