A jug has an essentially square base, four sidewall portions rising from the base formed together with corner portions, and a shoulder portion extending upward to a finish portion defining an opening into the jug interior. Creases intersect a midline crease on two opposite sidewalls of the jug. A base crease line folds upward and the two opposite creased sidewall portions folds inward along vertical midline creases above diagonal crease lines from lower corners of the jug as the jug is moved from a full-sized use conformation toward a compact conformation. A sidewall, other than the two opposite creased sidewalls, can include an integrally formed handle, or can include a horizontal groove adapted to engage a lower end of a separately molded handle engaging the neck of the jug. A cap including a movable ring can engage a tab protruding from a groove in the sidewall to ensure a rolled compact arrangement of the empty jug. |
