Abstract (en)

[origin: EP0286285A2] A gable-top thermoplastic coated container with controllably enhanced sealing and opening characteristics includes at least one fillet (56) attached to the panels which form the pouring spout. The fillet comprises a thin strip of still material coated with a layer of adhesive. The strip extends along a portion of the panel length to increase the applied opening force which may be transmitted to the tip of the spout where the gable rib panels are adjoined and prevent buckling of the spout panels. The unadhered surface of the strip does not strongly adhere to the opposing thermoplastic coated panel, so that the spout may be opened with a controlled low force, without tearing or delamination of the carton panels. The portion of the fillet-carrying panel not covered by the fillet will bond to the opposing panel by thermoplastic fusion. Preferably, the adhesion layer is of such a thickness that a portion thereof is extruded during the carton sealing process, forming a bead of adhesive along the edges of the strip to bond opposing panels together. The result is a hermetic seal which is readily opened without destruction of the spout panels.
