The present invention relates generally to pouches, and more particularly to a former to form pairs of dispenser pouches of the flexible three-sided sealed type. The former has a continuous foil channel and outer guide surfaces for a foil strip to be reshaped into a double tube, which enters the channel through a foil supply edge. A pair of form- and filling pipes are arranged in the channel, which has a back wall, two front walls having two form edges, and sidewalls that are adapted to the cross-section form of the filling pipes. The wedge-shaped form edges of the front walls delimit a slit in the lower part of the former. The back wall and the form edges of the front walls, proceeding from the foil supply edge and a section that converges in continuous direction between the front walls, are developed relative to one another and continually approaching until the end of the downwardly open slit.

Former for a packaging machine to form pairs of three side sealed pouches from packaging foil material

Tooling to form pairs of dispenser pouches

A three-sided pouch formed from a sealable foil comprises two parallel longitudinally extending tubular chambers. A longitudinal bendable sealing seam separates the chambers. Transversely extending sealing seams close the opposite ends of the tubular chambers. In order to enable such pouches to be easily opened, one of the transversely extending seams has a widened portion straddling the longitudinally extending sealing seam and extends to both tubular chambers. A tearing aid for facilitating the tearing open of the two tubular chambers is arranged in the widened portion.

Sealed three-sided pouch with two chambers

Dispenser pouch

The invention is concerned with tubular bag-type packings in the form of so-called stickpacs formed of a sealable foil strip of at least one layer which is molded to form a tube provided with a longitudinal sealing joint extending between the side edges of the packing. The tube is sealed by upper and lower transverse sealing joints. In order to enable such stickpacs to be easily and faultlessly opened, in one instance, also in the area of the longitudinal sealing joint, tearing aids are provided, and in another instance, the tube, via a transverse sealing joint, is provided with an extension, with the transverse sealing joint being arranged to extend at an inclination relative to the longitudinal axis of the packing.
