Sealed gable top carton having a mouthpiece of one piece molding

A gable top carton for containing a liquid product, comprising a boxlike body having a closed bottom, a sealed gable top closing a top end of the boxlike body and having a pair of oppositely sloping sides with a ridge formed therebetween, one of the sloping sides of the gable top having defined therein an aperture for pouring out the contained liquid product, and a mouthpiece of one piece molding liquidtightly closing the aperture in one of the sloping sides of the gable top, said mouthpiece including a lid having a pull tab projecting therefrom and being formed to include a substantially tubular spout protruding outwardly from the aperture in the gable top, the spout being open at an inner end to the interior of the body and having an outer end closed by the lid, said lid having a hinge end located close to said ridge and a tear end located away from the ridge, said lid being defined by a relatively shallow, linear first groove cut in the hinge end of the lid and by a second groove of greater depth than the first groove extending from the tear end of the lid toward the opposite extremities of the first groove along a pair of opposite sides of the lid, said pull tab being formed adjacent the tear end of the lid, whereby upon exertion of a force on the pull tab, the lid is torn along the second groove, the first groove serving to provide a hinge connection between the torn lid and the spout, said pull tab of the mouthpiece being formed to include a limit stop protruding therefrom for engaging the outer end of the spout when the lid is reclosed after having been torn open, thereby preventing the lid from being depressed too far into the spout, said pull tab having formed therein an indentation which is located farther away from the lid than is the limit stop, whereby when the lid is reclosed by pushing the pull tab after having been torn open, the pull tab is collapsible at the indentation and so is prevented from being depressed into the spout beyond the limit determined by the limit stop on the pull tab.
