  Such a carton generally includes a top wall, a pair of side walls connected to both edges of the top wall, and a bottom wall connected to the pair of side walls, and an object to be packaged can be disposed therein. It is formed in a cylindrical shape. Moreover, both ends of the carton are open ends.

  Moreover, a plurality of cans can be cited as an item to be packaged to be placed inside the carton. For example, in a general carton, six cans are arranged in 2 columns × 3 rows with the carton surrounding the upper end portion, the peripheral wall, and the lower end portion of the can.

  Such a carton is preferred to save blank material. However, since both ends of the carton are open ends, such a carton must be provided with an article holding means for appropriately holding an article to be packaged inside the carton.

  Such article holding means may be formed from a recessed support tab, or may be formed by an article receiving opening and a recessed support tab projecting toward the article receiving opening. These recess support tabs are generally formed in a substantially rectangular shape, and the width thereof is constant (see Patent Document 1 and Patent Document 3). Further, in order to engage such a recessed portion supporting tab with the recessed portion at the upper end portion or the lower end portion of the can, the recessed portion supporting tab is pushed into the recessed portion at the upper end portion or the lower end portion of the can after the carton is placed on the can. There was a need.

  Furthermore, since a predetermined space is formed between the recess support tab and the edge of the article receiving opening, the edge of the recess support tab is arranged apart from the edge of the article receiving opening (patent) Reference 2). Therefore, when the blank is punched to form the article receiving opening, it is necessary to remove the small piece formed between the recess support tab and the article receiving opening. Such a piece has a wedge shape that tapers towards the connecting end of the recess support tab.
