A self-locking, tamper-proof container is made of a paperboard material, and includes a tubular body portion, and a cooperating cover portion. The tubular body portion has a generally rectangular planar base portion, and a side wall formed of two opposed pairs of upstanding panel members. Two locking flaps are respectively hingedly connected to one pair of opposed upstanding panel members, with each locking flap being disposed on the outside surface of the associated panel member and extending downwardly. The cover member is of slightly large plan area than the base portion of the tubular body, and two opposed upstanding panels thereof are formed by side panels and folded-under elongated tab portions. Each tab portion has a U-shaped cut-out such that in the erected condition of the cover member, two locking pockets are disposed on the inside surface of the two opposed upstanding panels. The locking pockets cooperate with the locking flaps of the body portion when the cover member is telescopingly received by the body portion to thereby inhibit removal of the cover member from the body portion. The tubular body portion and the cover member are each formed from a blank of paperboard material.
