  As shown in FIG. 8, this embodiment is different from that shown in FIG. 1 only in the configuration of the opening structure 240. The unsealing structure 240 in this embodiment includes a plurality of cut lines 241 arranged in two rows in a direction orthogonal to the connecting direction of the first paper piece portion 210 and the second paper piece portion 220, and the two rows of cut lines. It is composed of an opening band 242 that is sandwiched between 241 and separated from the surface sheet 205 by connecting a plurality of cut lines 241. Each of the plurality of cut lines 241 has a side 241a extending in the arrangement direction of the plurality of cut lines 241, one end connected to one end of the side 241a, and the other end of the opening band 242. Side 241b facing the opposite side, one end is connected to the other end of the side 241a, the other end is directed to the side opposite to the opening band 242 and the extension line is adjacent to the cut line It is comprised from the side part 241c which faced the direction which cross | intersects the side part 241b of 241. FIG. That is, the only difference is that the end portions of the side portions 241b and 241c constituting the cut line 241 are directed to the side opposite to the opening band portion 242 with respect to that shown in the first embodiment. .

  Even in the concealment postcard 201 configured as described above, like the concealment postcards 1 and 101 shown in the first and second embodiments, the unwrapping band portion 242 is inclined with respect to the arrangement direction of the plurality of cut lines 241. Even when pulled in the direction, it can be opened without causing paper peeling or the like.

  In the above-described three embodiments, among the end portions of the cut lines 41, 141, and 241, the side portions 41b, 141b, and 241b side, that is, the end portion that is the break receiving side is formed in a Y-shaped fork shape. It is also possible to do.

  In the three embodiments described above, the concealing postcards 1, 101, and 201 having the opening structures 40, 140, and 240 using the separation structure of the present invention have been described as examples. 40, 140, 240 are not limited to the concealment postcards 1, 101, 201 as described above, but can also be used as an opening structure for opening a box such as a confectionery box.

  Further, the separation structure of the present invention is not limited to the configuration in which the plurality of cut lines 41, 141, 241 are arranged in two rows, like the unsealing structures 40, 140, 240 shown in the above-described three embodiments. As long as the plurality of cut lines 41, 141, 241 are arranged in one direction, they may be arranged in a line. For example, in a delivery slip provided with a separation region such as a receiving piece, the separation region can be separated from other regions using a separation structure in which a plurality of score lines 41, 141, 241 are arranged in a line.
