Abstract: A container has a top and a bottom endcap, a bottle sandwiched therebetween, and one or more bands coupling the top and bottom endcaps and the bottle. The bottle receives therein a flexible bladder. At least one of the top and bottom endcaps has a pair of opposing parallel surfaces, one of which has a protrusion extending therefrom and the other one of which has a recess therein at a location corresponding to that of the protrusion. A valving structure demountably engages with a neck portion of the bottle and has (i) a coupling valve assembly having two channels in fluid communication with the bottle and the bladder for injecting gas thereinto and dispensing liquid therefrom, respectively, and (ii) a twist-lock casing receiving therein the coupling valve assembly and removably coupled to the bottle's neck portion. The twist-lock casing has a structure for safely depressurizing the bottle.
