Abstract

A beverage cooler carton is provided which is intended to receive ice or other cooling means to keep contents packaged therein cool. The carton is made of a material which is impervious to liquid which may be contained within the carton during use. The carton includes folding end panels which extend continuously between adjacent upper and lower panels; therefore, there are no seams or breaks in the material around a periphery of the carton which might degrade the ability of the carton to hold a liquid. Also disclosed is a method of assembling the cooler carton.

Claims

1. A carton for holding a plurality of products, said carton comprising:

a plurality of panels including opposing front and rear panels, an upper panel opposing a lower panel, and opposing end panels, said plurality of panels when assembled forming the carton enclosing an interior open space;

said end panels each including an upper flap attached to said front panel, and a lower flap attached to said rear panel;

a pair of foldable side flaps interconnecting said lower flap to said upper and lower panels;

said front panel being substantially planar and constructed of a continuously extending sheet of material, and a plurality of perforations formed thereon defining an access opening when said perforations are broken to expose said interior open space, said front panel remaining as a single unitary member prior to breaking of said perforations;

wherein said rear panel, said upper and lower panels, and said end panels form a continuous and unbroken liquid containment area for holding an amount of liquid therein; and

said plurality of perforations define a plurality of access panels which are foldable away from said front panel and which communicate with said access opening, said plurality of access panels terminating at locations spaced interiorly from a periphery defining said front panel.

2. A carton, as claimed in claim 1, wherein:

said top panel includes a handle attached thereto.

3. A carton, as claimed in claim 1, wherein:

each said foldable side flap includes an upper side flap having an edge connected to an adjacent upper or lower panel, and a lower side flap having an edge connected to said lower flap.

4. A carton, as claimed in claim 3, wherein:

said foldable side flap includes a diagonal fold defining an interface between said upper side flap and said lower side flap, said diagonal fold allowing said upper and lower side flaps to be folded against one another when said lower flap is folded towards said carton.

5. A carton, as claimed in claim 4, wherein:

each said upper side flap includes a notch formed thereon facilitating folding of said upper side flap against said lower side flap.

6. A carton, as claimed in claim 1, wherein:

said carton includes a liquid level line defining a recommended maximum fill line for liquid in said carton.

7. A carton, as claimed in claim 1, wherein:

said carton is made from a single sheet of pre-cut material.

8. A carton, as claimed in claim 1, wherein:

said carton is made of composite material including a substrate and a liquid impermeable film bonded to said substrate.

9. A carton, as claimed in claim 8, wherein:

said liquid impermeable film includes a polyethylene film.

10. A carton, as claimed in claim 8, wherein:

said liquid impermeable film is bonded to said substrate by a polyethylene extrudate.

11. A carton, as claimed in claim 1, further including:

a tab located between at least two opposing access panels of said plurality of access panels and connected to a third access panel of said plurality of access panels.

12. A carton, as claimed in claim 1, wherein:

said carton further includes a plurality of slots positioned on edges of said front panel and said opposing end panels to facilitate draining of leaking containers or condensation, or to prevent overfilling during use.

13. A carton for holding a plurality of products, said carton comprising:

a plurality of panels formed from a single sheet of material, said material being liquid impervious;

said plurality of panels including opposing front and rear panels, opposing upper and lower panels, and opposing end panels, said plurality of panels when assembled forming the carton enclosing an interior open space;

said rear panel, and lower portions of said upper, lower, and end panels defining a continuous and unbroken liquid containment area;

said front panel being substantially planar, and said front panel having a plurality of perforations formed thereon defining an access opening when said perforations are broken to expose said interior open space

said end panels each including an upper flap remaining attached to said front panel, and a lower flap remaining attached to said rear panel; and

said plurality of perforations defining a plurality of access panels which are foldable away from said front panel and which communicate with said access opening, said plurality of access panels extending from a center area of said front panel and terminating at locations spaced interiorly from a periphery defining said front panel.

14. A carton, as claimed in claim 13, wherein:

said material includes a liquid impermeable membrane applied thereto to make said material liquid impermeable.

15. A carton, as claimed in claim 13, wherein:

said carton further includes a plurality of slots positioned on edges of said front panel and said opposing end panels to facilitate draining of leaking containers or condensation, or to prevent overfilling during use.
