<P>PROBLEM TO BE SOLVED: To provide a bottle container with a cap, which provides an engaging part between the bottle and the cap with high resistance against the inner pressure of the bottle. <P>SOLUTION: The container 2 comprises a container body 5 for holding a content, which has one end having openings 5a, 6 and the other end that is closed, and the cap 10 for closing the openings 5a, 6 of the container body 5. A screw thread 7 is formed on a part of the openings 5a, 6 of the container body 5, and the cap 10 is engaged with the screw thread 7 to hermetically close the container body 5. The screw thread 7 has a first sloped line 7a that slopes down from the peak of the screw thread 7 toward one end of the screw thread 7, and a second sloped line 7b that slopes down from the peak of the screw thread 7 toward the other end of the screw thread 7. The slope angle B that is formed between a base line 1, which extends in perpendicular to the axis of the container body 5 from the peak of the screw thread 7, and the second sloped line 7b is made smaller than the angle A that is formed between the base line 1 and the first sloped line 7a. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
