<P>PROBLEM TO BE SOLVED: To provide a synthetic resin container with a lid whose ceiling wall permits a straw to be inserted, where a leading edge of the straw is properly led to a breakable line on a portion to be fractured even when the leading edge of the straw is erroneously positioned nearby a central part of the upper surface of an opening area. <P>SOLUTION: The lid of the synthetic resin container has the ceiling wall in addition to a skirt wall suspending from a periphery of the ceiling wall. An opening area 50 on the ceiling wall is specified by a circular breakable line 48. On the upper surface of the circular area 50 encircled by the circular breakable line 48, a gradient 51 starts inclining from a central part to a radius exterior direction. <P>COPYRIGHT: (C)2004,JPO |
