ABSTRACT:
A paper container according to the present invention includes a tab region half cut for defining a tab region of a shape whose lower part is closed and whose upper part is opened in the substantially central part of one of top folded-in side panels. A stopper is applied to an upper end of the tab region or near the upper end. The tab region is pulled from below after a pair of top folded-in side panels are separated apart, whereby a tab is formed, and the tab is pulled to split the seal between the top ribs and then the top folded-in ribs, and then the seal is opened. The tab region half cut is simply provided, and a stopper is simply provided for prohibiting breakage of the tab. The tab is not raised until the seal is opened, so that the tab does not get in the way of manufacturing the container. The apparatus of the present invention cuts plastic tape to a desired length to form a stopper, heats the stopper prior to being applied to a blank for a paper container, and press applies the stopper to a blank for a paper container which is conveyed by a conveyor.
