A carrier has a bottom, a plurality of side panels connected to the bottom, and a handle panel. The handle panel is connected to one of the side panels or the bottom. The handle panel includes a fold line, a first aperture, a second aperture, a first perforated line in continuation of the first aperture and the second aperture, and a second perforated line defining a finger opening in the handle panel. Pressure applied on the first perforated line tears apart material to produce a third aperture in continuation of the first aperture and the second aperture. Pressure applied inside the second perforated line dislocates material to produce the finger opening. When the third aperture is open in continuation of the first aperture and the second aperture, the handle panel folds along the fold line over a container to facilitate penetration of a handle of the container through the first aperture, the second aperture, and the third aperture.
