Abstract

The present invention provides a fully enclosed wrap-around carton for bottles and cans that can be tightly packaged. The carton has triangular panels between the ends of the lower side panel and each lower end flap that diverge away from the bottom panel. There are a pair of triangular panels between the sloping upper side panel and each upper end flap that diverge away from the top panel. These triangular panels tighten the carton against bottles or cans packaged therein.

Claims

1. A fully enclosed wrap-around carton for containing a plurality of cylindrical articles comprising:

(a) a bottom panel with sides and ends, which is attached at each side to a lower side panel, which rises perpendicularly from the bottom panel and which has ends and an upper side which is attached to a sloping upper side panel with ends and a top edge which is attached to a top panel with ends and sides;

(b) a top end closure adjacent each end of the top panel formed by a top end flap foldably attached to an end of the top panel, an upper end flap which is foldably attached to the end of the sloping upper side panel via a pair of triangular panels that diverge away from the corner formed by the intersection of the top panel, sloping upper side panel, and top end flap, said flaps being secured together by securing means to form the closure; and

(e) a bottom end closure adjacent each end of the bottom panel formed by a bottom end flap foldably attached to an end of the bottom panel, a lower end flap, which is foldably attached to the end of the lower side panel via a pair of triangular panels that diverge away from the corner formed by the intersection of the bottom panel, the lower side panel and bottom end flap, said flaps being secured together by securing means to form the closure.

2. The carton of claim 1, wherein the securing means is glue.

3. The carton of claim 1, wherein each lower end flap is foldably attached to the adjacent upper end flap.

4. The carton of claim 3, wherein the triangular panels connecting the upper end flap to the sloping upper side panel are foldably attached to the adjacent triangular panels which are foldably attached between the lower side panel and lower end flap.

5. The carton of claim 2, wherein the bottom panel is attached at one side to a glue panel, which is glued to a lower side panel.

6. The carton of claim 1, wherein the distance between the ends and sides of the top panel is significantly less than the distance between the sides and ends of the bottom panel.

7. A bottle carton comprising:

(a) top, bottom and side panels, each side panel having ends and a lower portion and an inwardly inclined upper portion, said top, bottom and side panels being interconnected to form a tubular structure, said top panel having ends and being rectangular, a top end flap foldably joined to each end of said top panel;

(b) said bottom panel having ends and being rectangular with a significantly larger dimension than said top panel, with end flaps being foldably joined to each end of each portion of each side panel, with a pair of triangular corner panels between each end flap and side panel with said triangular corner panels adjacent the upper portion of the side panel diverging away from the top panel and said triangular panel adjacent the bottom portion diverging away from the bottom panel so as to grip the bottles in a taut fashion; and

(c) a bottom end panel attached to each end of the bottom panel and secured in overlapping relationship to the end flaps attached to the lower portion of the side panel, and said top end panel being secured in an overlapping relationship to the end flaps attached to the upper portion of the side panel.

8. The carton of claim 7, wherein the securing means is glue.
