<p>Cartons of the type used for domestic milk supply may be more readily opened if a portion of the ridge that extends above the wings of the carton is first severed between the wings and the heat sealed closure so that the severed portion of the ridge may be folded back from above the wings or removed by a further cut across the ridge to the first line of sever. The wings are then free to be folded back and pressed inward to open the carton to form a pouring lip. A device for opening cartons comprises a thin blade (109) secured to a handle (97) and hinged within a shrouded recess in a two-part housing (101). Handles (97 and 103) act about the double action hinge (100) to move the blade (109) across the slot (105) to sever a portion of the carton ridge positioned in the slot. A tongue (not shown) holds the device in alignment with the ridge to ensure that the severing is below the sealed portion of the ridge.</p> |
