Disclosed is a container made according to a method for manufacturing a sealed container filled with a liquid substance, comprising the steps of positioning a portion of an extruded tube in a blow mold to form a container having a body with a body diameter, a detachably mounted head to facilitate opening the container with a head diameter considerably smaller than the body diameter and a transition part between the body and the head substantially extending in a radial plane, the tube having a diameter slightly greater than the head diameter, the blow mold including main jaws between top jaws and a mold base, closing a bottom end of the tube forming a bottom of the container, blowing air into the tube, after the tube bottom end is closed, and simultaneously moving the mold base in a first movement toward the top jaws of the blow mold to decrease a space inside the main jaws, filling the container in the blow mold with the liquid substance, moving the mold base further toward the mold top jaws until the container is free of air and is completely filled by the liquid substance, and forming a top segment of the tube with the top jaws into the container head and sealing the formed container.
