The invention relates to an apparatus for the successive production of a number of paper packages fitted with respective spouts on a part of the top end portion thereof and charged with a liquid drink. The spout includes a spout proper having a general cylindrical outer configuration and formed generally therethrough with a liquid spouting passage provisionally closed or valved, and an attaching flange permanently fixed to the root end of the spout proper. For better sanitary purposes, the spout is introduced into the open end of a semipackage from inside thereof. The spout introduction and attaching job is carried out directly before charging with liquid. Only thereafter, liquid charging-in and top-closing jobs are carried out in a sterilized atmosphere. Within the sanitary execution of these jobs, the spout introducing and sealing attachment are included for increasing the sanitary safety.

A gable top carton for containing a beverage or like liquid product is diosed which comprises a boxlike body having a closed bottom and a double sloping top. The top has an aperture defined in one of its sloping sides for pouring out the contained liquid. Closing this aperture is a plastic mouthpiece of one piece construction, which is fused to otherwise watertightly attached to the edge portion of the top around the aperture. The mouthpiece includes a lid having a pull tab protruding therefrom. The lid can be torn open upon exertion of a pull on the pull tab. Preferably, the pull tab is formed integral with a hook capable of engaging the ridge of the gable top when the lid is torn open, so that the lid may be held fully open as the liquid is poured out.
