Packaging container with opening and closing lid

A packaging container with an opening and closing lid, the packaging container comprising:

• an outer case of a rectangular parallelepiped shape having an insertion and removal opening in an upper portion thereof and an inner case which is slidably housed in the outer case, can be inserted and removed from the insertion and removal opening, and has an opening and closing lid, a lower portion of which is rotatably connected to the inner case via a first hinge,
• a lid-raising means which has an upper portion connected to a rear end of the opening and closing lid via a second hinge, can move relative to the inner case as the opening and closing lid rotates, and has inner-case locking means arranged therein on a side facing an inner surface of the outer case, and outer-case locking means which is positioned on an inner side of the outer case and can be engaged with the inner-case locking means, wherein:
• the packaging container with the opening and closing lid is configured such that the inner-case locking means and the outer-case locking means engage with each other as the inner case moves upward, and the lid-raising means moves downward as the inner case moves upward in a state in which the inner-case locking means and the outer-case locking means engage with each other so that the opening and closing lid rotates in an opening direction;
• and
• the packaging container with the opening and closing lid is characterized in that an incision opening is formed by cutting a part corresponding to an edge of the lid-raising means in a rear side plate of the inner case,
• a stopper formed in a part of the incision opening below a height position of the inner-case locking means with an upper end edge of the stopper being an incision edge arranged at the lowest position of the outer-case locking means, and
• a width of the outer-case locking means is wider than that of the stopper, and at least part of a stopper-corresponding portion of the outer-case locking means, which the stopper approaches as the inner case moves upward, is in contact against the incision edge being the stopper,
• wherein a backing plate is arranged on an inner surface of a side plate, in which the lid-raising means of the inner case is provided, the backing plate covering the lid-raising means and the incision opening formed around the edge of the lid-raising means.

• a width of the outer-case locking means is wider than that of the stopper, and at least part of a stopper-corresponding portion of the outer-case locking means, which the stopper approaches as the inner case moves upward, is in contact against the incision edge being the stopper,
• wherein a slide operation opening is opened in a body portion of the outer case so that a part of the inner case is exposed from the slide operation opening, thereby being enabled to perform a slide-up operation with respect to the exposed part of the inner case.
