US Patent No. 4,738,365 issued on April 19, 1988 to Prater ;US Patent No. 5076439 issued on Dec. 31, 1991 to Kuchenbecker ;US Patent No. 5,085,323 issued on Feb. 4, 1992 to Kuchenbecker et al. ;EP Patent No. 697340 issued on October 28, 1998 to Inger GB Patent No. 1451138 MU 8400469-0 U issued to Filho and published on Oct. 25, 2005 PI 0205132-0 A issued to Bohlen et al. and published on November 25, 2002 - Document US-A-5 588 587 discloses a reclosable carton where an opening tongue is attached to a glue and score area.
- Surprisingly, it was discovered that a reclosable carton could be designed with a top panel having four separated fixed sections and a front panel with two fixed sections. These fixed sections are arranged in a specific relationship that allows easy opening and re-closing and maximizes access to the contents of the carton such as e.g. a soap bar or other items that are approximately as large as the container. Moreover it was unexpectedly discovered that end flap overlap could be minimized to speed carton blank production and conserve materials without the danger of end flap damage when the carton was opened, thus maintaining carton integrity.
- According to one aspect of the present invention there is provided a reclosable carton that is formed by folding a cut or stamped blank that includes a front panel and a top panel connected at a fold line where the front and top panels also have two spaced apart tear lines. The spaced apart tear lines define a reclosable portion extending across the fold line separating the front and top panels. The front reclosable panel has a finger tab connected at a fold line. The blank also includes a back panel connected both to a top panel at a fold line and to a bottom panel at a fold line. A glue panel is also connected to the bottom panel at a fold line, and further includes a locking slit flap connected to the glue panel at a fold line. Each of the front, top, back and bottom panels have opposite end flaps connected at fold lines to each of the front, top, back and bottom panels and each end flap has two spaced apart lateral edges and an axial edge. During assembly of the reclosable carton, the glue panel is attached to a front fixed section with adhesive, and the reclosable portion, finger tab and locking slit flap are kept free of adhesive.
- In further detail, and with each of the ensuing features being preferred, each of the tear lines has a first end and a second end, and each of the tear lines intersect the fold line between the top and front panels at a point at least 3 mm from each of the adjacent top panel end flap lateral edges at the first end. Each of the tear lines intersect the fold line between the top panel end flap and the top panel at a distance of at least 3 mm from the nearest end flap lateral edge. Each of the tear lines extend partially along each of the top panel end flap fold lines, wherein each of the tear lines is spaced at least 3 mm from each of the lateral edges of the adjacent top panel end flaps. Furthermore, each of the tear lines intersects the fold line between the top and front panels at a point at least 3 mm from the adjacent top panel end flap lateral edge. Each of the tear lines also intersects the finger tab fold line and each of the spaced apart second ends of the tear lines is positioned at the outermost edge of the finger tab.
- In addition the glue panel defines a locking slit, and the front reclosable section has a tuck flap connected to the finger tab at a fold line. The tuck flap is positioned to engage the locking slit when the finger tab is flexed in order to close the reclosable section of the carton after its initial opening along the tear lines.
