PURPOSE: To set the printed surface upward free from the trouble of breakage of a box and collar part itself due to an external pressure by forming the both edge parts of a collar part which spreads towards the end and is formed at one edge of a cylinder part into parallel state and forming a nearly vertical wall part of least at one edge part, thus forming a packing box into small-sized.

CONSTITUTION: A collar part 12 spreading towards the end is formed at the lower edge of a cylinder part 10, and a plurality of projections 11 in this stripe form for suppressing slip-off of thread are formed onto the outer peripheral surface of the cylinder part 10. The both edge parts of the collar part 12 are formed parallel each other, and formed into the nearly vertical wall parts 13 and 14, and the outside of one wall 13 is formed into shallow recessed part 13a. A label 20 bent into nearly U-figure form is applied onto the wall part 13, with the surface part 20a positioned at the recessed part 13a and with the back surface part 20b positioned at the back surface of the wall part 13. Further, the upper edges of the wall parts 13 and 14 are formed into circular form, and the surface part 20a of the label 20 is formed into the shape conforming to the shape of the wall part 13.
