<p>The object is to provide a packaging container which can improve the quality of a packaging material (10) and which does not restrict the types of usable lid members (13). The packaging container has a container body (12) and a lid member (13) welded to the top wall (12a) of the container body (12). The lid member (13) is composed of a main body portion (14) having an opening (21), as well as a lid portion (15) swingably supported by the main body portion (14). A rupturable portion (23) is formed in a discharge opening portion which is defined on the top wall (12a) at a predetermined position. The rupturable portion (23) is composed of a thin-wall portion (24) formed through reduction of the thickness of the packaging material (10) constituting the container body (12) and a rupture-line area formed through formation of a rupture line portion surrounding a predetermined area. When the lid member (13) is attached to the container body (12), the lower surface of the lid portion (15) is bonded to the predetermined area at at least a portion adjacent to the thin-wall portion (24). Since the lower surface of the lid portion (15) is bonded to the predetermined area at a portion adjacent to the thin-wall portion (24), when the lid portion (15) is pulled up and rotated, the rupturable portion (23) is ruptured, so that the packaging container is opened. <IMAGE></p> |
