Abstract (en)

[origin: ES8100202A1] An opening structure preferably located in a top panel of a one-way packaging container provides a pour opening which can be reclosed after the initial opening. The structure is prepared by positioning and sewing a portion of a strip of web material on the panel, defining a pour opening area within the secured strip portion by applying a cut or weakening line forming a boundary. The pour opening area of the panel is retained in its original position in the panel. Then a second, unsecured portion of the strip is folded back over the first portion to cover the first portion and the pour opening area. Securing zones are produced to secure the second strip portion to the panel both within the pour opening area and a surrounding region to thereby obtain a hermetically sealed opening structure on the packaging container. The pour opening is uncovered by lifting the second strip portion so that the cut-out section of the panel is removed. After the desired quantity of the contents of the container has been discharged, the second strip portion and the cut-out section of the panel attached thereto is folded back over the pour opening so that snap-action engagement of the edges of the cut-out panel section with the edges of the pour opening results in a closure which, although no longer hermetically sealed, is mechanically secured.
