PROBLEM TO BE SOLVED: To propose a tab material capable of easily grasping an opening operation at an opening time and hardly slipping at a finger tip. ! SOLUTION: A tab material (5) encapsulates the opening (4) of a packaging container (1) by sealing the opening (4) thermally, and the tab material (5) has its knob part (6) formed with a notch line (7) shaped to have its one end opened on the side close to the leading end of the knob part. One end of the opened notch line is formed with a ridge-folding horizontal rule (8). This ridge-folding horizontal rule is folded to characterize the tab material in that the leading end of the portion enclosed by said notch line protrudes downward. ! COPYRIGHT: (C)2015,JPO&INPIT |
