That is, this sealing device includes a rotating body that sequentially receives Ronin containers sent from a filling machine, a lid supplying device that supplies a lid above the mouth of the container received by the rotating body, and a lid feeding device that supplies a lid above the mouth of the container. It consists of a heating device that heats the lid and a suppression device that presses the side of the container to expel excess air. After
At the point of the suppression device, the air inside the container is expelled and the seal is crimped onto the mouth of the container to form a seal, and the sealed containers are sequentially sent to the next process.

Problems that the invention aims to solve According to the above conventional configuration, there are the following problems.

■Normally, the mouth of the container is smaller than the body, so the conveyance pitch in the rotating body is considerably larger than the diameter of the mouth. Therefore, the heating device disposed along the peripheral edge of the rotating body along a predetermined range becomes larger and its effective range (range corresponding to the mouth) becomes narrower, which is uneconomical.

■At the time of an emergency stop of the machine, the heating device retreats from the container conveyance path of the rotating body, so the containers and lids in the heating section are not sufficiently heated and cannot be sealed. For safety reasons, the container and product were discarded at the exit of the sealing device, along with several containers and containers located at the front and back of the heating section, resulting in wasted product.

■Since the suppression device is located 111 positions outside the rotating body, it can only suppress from one side of the container, and therefore cannot achieve uniform suppression and has not been able to meet the recent demand for accuracy in the amount of suppression. . In addition, if the container does not stand on its own (such as a bag), a jig for it to stand on its own is required.
