Cardboard carton for granular materials

摘要

A cardboard carton for granules includes a lid having a locking recess. The carton also includes a downwardly folded tab which cooperates with the locking recess on the lid to retain the lid closed. The locking tongue is formed by forming a slit in a face plate of a folded cardboard portion of the front panel. The locking tongue is in the position along the face plate by a sealing member before the first use by users. Therefore, the leakage of the granules from the slit portion of the front panel can be prevented. In addition, users will not erroneously recognize the locking tongue as a tab to be removed before use.
