An object is to improve the quality of a packaging container (11), simplify the structure of a packaging container manufacturing apparatus while reducing the cost thereof. The packaging container (11) comprises a container body (12) formed from a packaging material (21), and a cap unit (C) attached to a cap attachment portion of a top wall (13) of the container body (12). The cap unit (C) includes a collar portion (15), a pull tab (17) which covers, from an outer side of the packaging material (21), a discharge opening portion defined on the packaging material to correspond to the cap attachment portion, an inner tape (31) which covers the discharge opening portion from a reverse side of the packaging material (21), and a lid portion (16) which is fitted into the collar portion (15) via the pull tab (17). In this case, since the cap (14) is attached to the packaging material (21) in advance, the cap (14) is not required to.be attached to the container body (12) after the container body (12) is positioned. Therefore, there is eliminated the necessity of stopping the container body (12) on a conveyer or temporarily removing the container body (12) from the conveyer and returning it onto the conveyer after attachment of the cap (14). Accordingly, variation in the position at which the cap (14) is attached is prevented, so that the quality of the packaging container (11) can be improved. In addition, the structure of the packaging container manufacturing apparatus can be simplified, and the cost of the packaging container manufacturing apparatus can be lowered. <IMAGE> |
