<p>PROBLEM TO BE SOLVED: To provide an automatic lid device of a synthetic resin container, in which automatic engagement of a lid is made with both lid-integrated and lid-separated containers by a same device, with no hooking failure occurring.SOLUTION: There are provided a conveyor 20 for transporting a synthetic resin container 10a in which a desired housing object is put, and a required number of hooking part engagement operation mechanisms 22a-22d for pinching an upper part and a lower part of a hooking part of the synthetic resin container 10a individually on both sides along advancing direction of the conveyor, being at positions separated by an interval along the advancing direction. A synthetic resin container that is sent on the conveyor 20 is stopped at a predetermined position, and a hooking part 8 of a container body 1 and a lid 2 is pinched by respective hooking part engagement operation mechanisms from above and below, so that the flanges of the container body 1 and the lid 2 are pressurized to the sides approaching each other for individual engagement of the respective hooking parts.</p> |
