PURPOSE: To improve operability for a pull-tab while maintaining connecting strength therefor for a pull-top device for a container, and to improve productivity therefor in injection molding while reducing fraction defective therefor. CONSTITUTION: A pull-top device 4 for a synthetic resin container 2 for arrowroot starch is constructed in a structure wherein a yielding line 8 is provided at the bottom wall 6 of the container 2 for arrowroot starch along its outer periphery, a pull-tab 10 approximately in a ring shape in a size allowing a finger to be inserted therethrough is connected to the outside of the bottom wall 6 on a point near the inside of the yielding line 8, and the bottom wall 6 is available for being removed partially along the yielding line 8 with the pull-tab 10 being pulled. The pull-tab 10 is connected through two supports 12 and 12, and one end of the pull-tab 10 is connected to the support 12 on one side while the other end of the pull-tab 10 is connected to the support 12 on the other side. |
