[0016]

Since the present invention is configured as described above, it has the following effects. 1. Since it is not necessary to prepare a partition separately from the container, the materials used can be reduced. 2. Since the partition supports the frame panel portion, it can be reinforced in terms of strength. Therefore, there is no risk of damage even if the containers containing the packed products are stacked. 3. The inside of the container is divided into two by the front auxiliary / dividing wall 6B and the rear auxiliary / dividing wall 6C, so that two packs can be reliably stored. 4. In the case where the connecting standing piece 7A as the upper and lower connecting portions 7 and the connecting receiving groove 7B are provided, when the packaging containers are stacked vertically, the connecting standing piece of the packaging container located below is located above. Since it is in the state of being inserted into the connection receiving groove of the packaging container, the reliable stacked state can be maintained.
