To reliably lock a bottle or the like with a simple structure and to prevent the bottle or the like from rattling and dropping off by a method wherein while a pasting method is essentially employed to eliminate a play of a packaging carton, ends are engaged to eliminate a widthwise shift.

The strip-like packaging carton for rolling a standing bottle or the like longitudinally and coupling ends at a bottom of the bottle or the like for locking the bottle or the like in a hole or the like has respective ends formed with adhesive parts 11, 12 to be stuck over the other ends 6, 5, while the ends 5, 6 are formed with an engaging structure for preventing relative movement in a widthwise direction between the ends. The engaging structure is constituted of a tab 13 and an insertion hole 14.
