Abstract

A carton of the wraparound type comprises top (18) and bottom panels (12, 24) connected together by spaced side wall panels (14,16:20,22) forming a tubular structure has a set of end panels at each end of the tubular structure to close the ends of the carton. Each set comprises a pair of end closure panels hinged to respective ones of the side wall panels and folded towards one another to close the end. Each of the end closure panels (38, 38'"'"':52, 52'"'"') are connected to upper parts (16, 20) of the adjacent side wall panels by an interconnecting panel (70, 70'"'"': 80, 80'"'"') which secures upper parts (38a, 1538a'"'"': 52a, 52a'"'"') of the end closure panels in a closed position such that they extend inwardly and upwardly.

Claims

1. A carton of the wraparound type for bottles which carton comprises top and bottom panels connected together by spaced side wall panels thereby forming a tubular structure and a set of end panels at each end of the tubular structure to close the ends of the carton, each said set comprising a pair of end closure panels hinged to respective ones of the side wall panels and folded across that end of the tubular structure towards one another, and an intermediate panel hinged to the top panel of the carton, each of said end closure panels being hinged to respective ones of the adjacent side wall panels at least in part by an interconnecting panel and to said intermediate panel by means of respective gusset panels, said intermediate panel and the associated gusset panels being disposed in superposed relationship with respect to said top panel when the end closure panels are closed, and said interconnecting panels being disposed in overlapping relationship with upper parts of said side wall panels.

2. A carton according to claim 1, wherein upper parts of each end closure panel are sloped inwardly and upwardly.

3. A carton according to claim 2, wherein said intermediate panel and each of said end closure panels are connected by hinged panels constituting said upper parts of said end closure panels.

4. A carton according to claim 2, wherein said interconnecting panels are hinged to upper parts of the adjacent side wall panels, to upper parts of the adjacent end closure panels and to said intermediate panel.

5. A carton according to claim 2, wherein said gusset panels are connected to said intermediate panels and said upper parts of said end closure panels.

6. A carton according to claim 1, wherein each of said end closure panels is connected to a bottom panel by foldable gusset panels adapted to provide a two-ply element at each lower corner of said carton.
