  • Patent number: 4817866
    Abstract: A packaging carton (e.g. for cans (31) of drink) comprises a reinforcing tape (18) incorporated in the board material from which the carton is formed which tape reinforces a carrying handle (20) defined by two parallel cuts formed in an end wall of the carton. Access to the contents of the carton are obtained by defining access flaps (23, 24) delimited by lines of weakness (22a, 22b) which extend up to the cuts defining the carrying handle. By locating the handle (20) in the median plane between two rows of cans, free passage of cans from the opening provided by an access flap is prevented by the handle, thus ensuring one-by-one dispensing of the cans from the carton.
