The present invention provides a packaging container that can be opened with a simple structure, the packaging container comprising a bag assembly having first and second sealing sections formed at two opposite sides of four sides, and a third sealing section where one side of the remaining two sides is a folding line, wherein the one remaining side is opened. The application also discloses novel methods for synthesis of these compounds and methods of using these compounds. The source composition can be, e. The printed wiring board includes an output port that alternatively outputs one of the data of whether or not the option function is being executed and the data of the drive condition of the compressor, and the printed wiring board performs data output processing from the output port in accordance with the display setting data that the switch has received. Finally, the first number differs from the second number. The resulting golf ball of the present invention provides for enhanced playability characteristics without sacrificing distance or durability properties.
