ABSTRACT:
A container includes a substantially rigid upper container segment, a flexible bladder integral with, and depending from, the upper container segment, and a lower substantially rigid container segment attached to the upper container segment so that the flexible bladder is housed therein. The upper container segment presents a smooth exterior continuation of the lower container segment so that the two segments visually appear to be formed in a unitary manner. A foldable hanger may be provided integrally on the bottom wall of the container so as to facilitate the container's supported inversion. In one embodiment, the bladder is spaced from the container bottom wall so as to establish a sub-container therebetween. A self-closing dispensing cap is provided which includes a pair of resilient, flexible sealing lips which are defined in part by an elongated discharge slit. An overcap is also provided which includes additional sealing means for engaging the sealing lips when the overcap is in a closed position.
