ABSTRACT:
A paperboard container composed of a unitary, continuous blank comprises opposing top and bottom walls, a plurality of side walls bridging the top and bottom walls, and a paperboard pour spout closure. The plurality of side walls includes a first side wall, and a top major flap extends from an upper end of the first side wall and forms a portion of the top wall. A backboard is coupled to the top major flap and includes a plug. The inner surface of the backboard is adhered to the inner surface of the first side wall. A closure layer is formed in the first side wall and is adhered to the plug. The closure layer and the plug form the pour spout closure. The pour spout closure is pivotally coupled to the first side wall for movement between closed and open positions. The plug is detachably linked to a remainder of the backboard. The plug is linked to the backboard when the pour spout closure is initially in the closed position. The plug is detached from the remainder of the backboard and leaves behind a hole in response to opening the pour spout closure. The plug is inserted into the hole in response to reclosing the pour spout closure. The first side wall forms at least one prong adjacent to the closure layer. The prong engages the plug in response to closing the pour spout closure.
