PROBLEM TO BE SOLVED: To prevent scattered contents from adhering to fingers or the like even when contents scatter when a seal material breaks.SOLUTION: The opening member 17 of a lid body 5 is coupled with a top wall part 6 via a first hinge part 21 to keep a side end edge of the opening member 17 coupled with the top wall part 6 via a connection plate 18. The connection plate 18 keeps widths in longitudinal directions gradually wider from the rear side to the front side and extends by directing gradually upward to the side of the opening member 17 along the longitudinal directions. The opening member 17 and the top wall part 6 are coupled with the connection plate 18 via a second hinge part 22. The opening member 17 comprises a pair of right and left first cutting blades 31 extending in cross directions and projecting downward and second cutting blades 32 extending in longitudinal directions between intermediate parts in cross directions of these first cutting blades 31 and projecting downward to make the first cutting blades 31 increase projection amounts directing gradually downward with approach to the second cutting blades 32 along the cross directions. |
