  • Patent number: 7883000
    Abstract: The present invention is directed to a paperboard container having generally finger access or handhold openings forming carry handles in the end walls. The handhold openings are defined by two adjacent tapered punch-out panels aligned end-to-end and hinged at their outer ends to a respective end wall. When two adjacent tapered punch-out panels punched out they fold oppositely to one another and inwardly into the container in laterally spaced relation to one another on opposite sides of the respective openings. A tear-out panel in one end wall adjoins the associated hand hold openings and when removed forms a dispensing or pourable opening immediately below the associated hand hold openings.
