A carton with a configurable dispenser that can be opened while resting on its side or on its bottom wall and that can dispense articles one at a time, in groups, or in a wholesale fashion. A restricted opening is formed by at least partial detachment of a dispensing flap, which permits limited access and side dispensing. An access opening is formed by at least partially detaching an unloading flap, which enhances the degree to which articles can be accessed and is useful for top unloading. The dispensing flap and the unloading flap are defined by two pairs of severance lines that diverge from a hand hold, dust flap or other tear initiation means and toward the side walls. The tear initiation means is off center, being positioned closer to one of the side walls of the carton than the other. Retention flaps cooperate with the remaining one of the dispensing flap and the unloading flap to restrain articles, particularly when the articles are dispensed while the carton rests on its side. Alternatively, both the dispensing flap and the unloading flap can be at least partially detached to enhance access to the articles for top unloading. Access can be maximized by detaching the retention flaps as well.
