The present invention relates to a method of manufacturing a manually openable container (10) of a collapsible type for fluid contents, comprising making a container (10) with a defined compartment (5) from a web of material (1). A top corner portion of the container (10) is designed to define a product channel (7) and an opening initiation (20) is formed across said product channel (7), along which opening initiation (20) a tab (6) is to be separated. The opening initiation (20) comprises a starting portion (21), a stop portion (22) and a terminating portion (23), the starting portion (21) requiring a first separating force (F1), and the terminating portion (23) requiring a second separating force (F2). The distance between the starting portion (21) and the terminating portion (23) forms said stop portion (22), which requires a third separating force (F3), which third separating force (F3) is greater than the first (F1) and the second (F2) separating force. The web of material (1) is formed with an intermediate, folded bottom-wall-forming portion (3) so that the compartment (5) of the completed container (10) is defined by two opposite side walls (12a, 12b) and a bottom wall (13), and the terminating portion (23) is given an extent both in the connecting portion (4) on a second side (25) of the product channel (7) and in the product channel (7). |
