Description

  The present invention relates to a container inner stopper, a container lid, and a method for producing a container with a lid.

The inner stopper is usually fitted into the mouth and neck of the container body by plugging, but at the time of stoppering, the liquid filled in the container jumps and jumps out of the outlet of the inner stopper, so that the stopper is plugged to prevent this. The outlet has been closed before. As a means for closing, for example, as shown in FIG. 3, before the inner plug 202 is plugged into the mouth and neck portion 201 of the container body 200, the inner cap 204 is screwed into the inner plug dispensing cylinder 203. Further, it is known that the overcap 205 is fitted to the container body 200 at the time of shipment, or the lower end of the peripheral wall of the inner plug fitted into the container body neck is closed with a pressure-breakable closing plate.
