The at least one window flap is connected at its hinged connection (68) to the first wall (16) for movement between a first position in which the at least one window flap is coplanar with the first wall and a second position in which the at least one window flap extends into the interior volume to define a window (66) in the first wall through which one of the articles is exposed to view. The at least one window flap (64) is allowed to move unimpeded by the one article when moving from the first position to the second position whereas it is in engagement at its free end edge at least in part with the one of the articles when in the second position.
A package comprising a carton and a plurality of articles, the carton comprising primary walls defining an interior volume in which the articles are received, a first wall of the primary walls comprising at least one window flap struck from the first wall, the at least one window flap having a hinged connection and an opposed free end edge, the at least one window flap being hingedly connected at the hinged connection to the first wall for movement between a first position in which the at least one window flap is coplanar with the first wall and a second position in which the at least one window flap extends into the interior volume to define a window in the first wall through which one of the articles is exposed to view, the at least one window flap is sized and shaped such that the at least one window flap is allowed to move substantially unimpeded by the one of the articles when moving from the first position to the second position and such that the at least one window flap is in engagement at the free end edge at least in part with the one of the articles when in the second position, wherein the free end edge of the at least one window flap is curved such that the at least one window flap has a greater width at an intermediate point along a length of the at least one window flap, than at either of opposed ends of the at least one window flap.
A carton for holding articles, the carton comprising primary walls defining an interior volume into which the articles may be loaded, a first wall of the primary walls comprises at least one window flap struck from the first wall, the at least one window flap having a hinged connection and an opposed free end edge, the at least one window flap being hingedly connected at the hinged connection to the first wall for movement between a first position in which the at least one window flap is coplanar with the first wall and a second position in which the at least one window flap extends into the interior volume to define a window in the first wall through which one of the articles in the carton is exposed to view, the at least one window flap being sized and shaped such that the at least one window flap is allowed to move substantially unimpeded by one of the articles in the carton when moving from the first position to the second position and such that the at least one window flap is in engagement at the free end edge at least in part with one of the articles in the carton when in the second position, wherein the free end edge of the at least one window flap is curved such that the at least one window flap has a greater width at an intermediate point along a length of the at least one window flap than at either of opposed ends of the at least one window flap.
A blank for forming a carton, the blank comprising primary panels for forming walls of the carton that define an interior volume of the carton into which articles may be loaded, a first panel of the primary panels comprises at least one window flap struck from the first panel, the at least one window flap having a hinged connection and an opposing end edge, the at least one window flap being hingedly connected at the hinged connection to the first panel for movement between a first position in which the at least one window flap is coplanar with the first panel and a second position in which the at least one window flap extends into the interior volume to define a window in the first panel through which one of the articles in the carton is exposed to view when the carton is erected, the at least one window flap being sized and shaped such that the at least one window flap is allowed to move substantially unimpeded by one of the articles in the carton when moving from the first position to the second position and such that the at least one window flap is in engagement at the free end edge at least in part with one of the articles in the carton when in the second position, wherein the free end edge of the at least one window flap is curved such that the at least one window flap has a greater width at an intermediate point along a length of the at least one window flap than at either of opposed ends of the at least one window flap.
