Document Type and Number:
Japanese Patent JP7070131
Kind Code:
B2
Abstract:
To provide a conical packaging container and a packaged food product that enable elaborate opening.SOLUTION: A packaging container 201 has a peripheral wall 10 where a blank is wound in a conical shape, and the other side end 24 is stuck onto one side end to form a conical peripheral surface. Tabs T1-T4 are formed at an upper side end so as to serve as origins for tearing a part of the peripheral wall in a belt-like shape. Helical break lines L1, L2 directed toward a conical bottom surface 12 side around a conical apex 11 are formed in a half-cut state in the peripheral wall so as to pass through the conical apex side ends and the conical bottom surface side ends of all the tabs and guide tearing of a tearing part 22. The break line extending from both ends of the tab closest to the conical bottom surface side has an end point P1 at a position of one round around the peripheral wall, tearing of the peripheral wall from the tab closest to the conical apex side to the end point is continuously guided by the break lines even at the stuck side ends, and the container is opened when the end point is reached in tearing from any tab.SELECTED DRAWING: Figure 1
