Abstract
The pack includes a box structure defining an inner cavity. A side of the box structure is sealed by a first adhesive. A lower end of the pack is sealed by a second adhesive connecting a rear surface of a lower panel of a front panel to a front surface of a lower glue panel of a back panel. The upper portion of the pack is circumscribed by perforated lines that cause the upper portion to remain connected to the tuck panel if the upper end of the pack is opened. The blank for forming the pack includes an upper portion of a back panel that is circumscribed by perforated lines. The method of making the pack includes applying an adhesive to the upper portion of the back panel and connecting a rear surface of a tuck panel to the upper portion.
