Abstract:
A unitary jug stackable with others of its kind, and capable of being produced by the technique of blow-molding from a two piece mold, said jug comprising:a shell enclosing a hollow interior, said shell comprising a walled exterior surrounding a walled aperture which fully penetrates said jug from one side thereof through to an opposing side, the aperture having a midsection where it is narrowest and widening toward its open ends, where it merges with said sides;an elongate tubular handle within and spanning said aperture at said narrowest midsection so that the jug is rotationally stable about the handle;closable entry means for admitting material to the interior of said jug;corresponding mutually engagable contours formed respectively on each said side in the region surrounding the periphery of said aperture and configured so that the contour of one side is fitably engagable with the corresponding contour on the opposing side, such that said jug is stackable with others of its kind, one said side being shaped to provide a stable base for supporting a stack of said jugs on a planar support surface;two inner parting lines defined within said aperture, one on either side of the handle, each describing a closed curve which follows the length of the handle and the narrowest part of the aperture;an outer parting line defined following said exterior wall at its widest point;wherein the exterior and aperture walls, where they flank said handle, extend substantially parallel to the length of the handle so that the minimum distance between any said inner parting line and said outer parting line, in any given region, is at least about one half of the distance between said first side and said opposing side in said given region, so that a maximum blow ratio of about two is not exceeded.
