ABSTRACT:
A bag-in-box composite container where the inner bag is easily separable from the outer box. In a preferred embodiment, a rigid one-piece outer box having a continuous side wall and a pair of end panels joined thereto defines a hollow box cavity. At least one of the end panels has a first aperture and at least two additional apertures therein. An inner bag is located within the hollow box cavity of the outer box. The inner plastic bag has a pouring spout with an annular flange connected thereto. The pouring spout extends through the first aperture in the end panel of the outer box. The annular flange of the pouring spout includes a pair of heat stakes which extend through the apertures in the end panel of the outer box. The heat stakes prevent relative rotation between the pouring spout and the outer box while temporarily securing the inner bag to the outer box. Upon emptying of the liquid contents, the inner bag is then separated from the outer box by depressing the pouring spout downward.
