A stackable plastic container has a unitarily formed handle on a top surface thereof. In accordance with a first feature, the top wall is provided with a pair of upwardly projecting portions that are asymmetrically disposed relative to a center line extending across the container and between which the handle extends. The bottom portion is provided with supporting and stacking nubs that are situated at positions corresponding to the projecting top wall portions, and the top wall portions have nub-receiving stacking recesses positioned on opposite sides of the handle so as to enable stacking of a like container on the container by engagement of supporting and stacking nubs of the like container in the stacking recesses of the container. According to a second aspect of the invention, a supplemental handle is provided which may be detachably attached to the container handle so as to convert the container from a single handle container to a triple-handle container, complying with military specifications for Jerry-type cans.

1. A stackable plastic container comprising: a blow molded container body of generally rectanguloid configuration having elongated top and bottom walls, a pair of major side walls and a pair of minor side walls; wherein said top wall is provided with a threaded neck-like opening, in the vicinity of one of said pair of minor side walls and centrally positioned relative to said major side walls, a pair of upwardly projecting top wall portions of the blow molded container body that are symmetrically disposed relative to a center line extending across the container between said major side walls, a first of said top wall portions substantially spanning between said pair of major side walls at a position adjacent said neck-like opening, a second or said top wall portions substantially spanning between said pair of major side walls in the vicinity of the other of said minor side walls and at the same height as the first portion, and a single bar-type handle extending, as a unitary part of said container situated centrally between said pair of major side walls, from said first top wall portion to said second top wall portion, and a central portion extending across said top wall, between said projecting top wall portions, at a position below said handle so as to form a hand opening; wherein said bottom wall is substantially planar except for the provision of a plurality of downwardly projecting, unitary supporting and stacking nubs, said nubs being situated at positions corresponding to said projecting top wall portion; and wherein said to wall portions have nub receiving stacking recesses positioned on opposite sides of said handle for enabling stacking of a like container on said container by engagement of the supporting and stacking nubs of the like container in said stacking recesses; further comprising a rigid supplemental handle means sized and shaped for insertion through said hand opening and for detechable engagement with said single, bar-type handle of the container top wall, said supplemental handle means having a pair of bar-type handle portions laterally spaced from each other and connected by crosspieces, notch means in the crosspieces for receiving said bar-type handle of the container top wall, and securing means for retaining the bar-type handle of the container within the notch means, whereby the container is convertible from a single handle container to a triple handle container. 2. A stackable plastic container according to claim 1, further comprising a threaded closure for said sealing the neck-like opening, and wherein said bottom wall is provided with additional nubs for supporting said container, said additional nubs being situated at positions corresponding to laterally opposite sides of said neck-like opening in a manner that the additional nubs of said like container stacked on the container will not engage against the container or said closure. 3. A stackable plastic container according to claim 2, wherein said threaded closure has a height which, when said closure is fully threaded to said neck-like opening, will have a top portion thereof in a common plane with a top surface of each of said top wall portions, whereby the top portion of the closure will supportingly engage a planar portion of the bottom wall of said like container between the additional nubs thereof. 4. A stackable plastic container according to claim 3, wherein said closure is a dual cap having a large diameter cap that is threaded for engaging with the threading of the neck-like opening of the container and which has a concentrically disposed aperture therethrough, and a small diameter closure cap for sealingly engaging with a neck-like projection of the large diameter cap which defines the upper end of said aperture through the large diameter cap. 5. A stackable plastic container according to claim 3, wherein said nubs, additional nubs and stacking recesses are spheric in shape. 6. A stackable plastic container according to claim 1, wherein said nubs, additional nubs and stacking recesses are spheric in shape. 7. A stackable plastic container according to claim 1, wherein the handle portions of the supplemental handle means are interconnected at each of opposite ends thereof by said crosspieces, and wherein said notch means comprises a centrally positioned notch in each of said crosspieces for engagingly receiving the bar-type handle of the container top wall. 8. A stackable plastic container according to claim 7, wherein, as said securing means the notches of the crosspieces have nub-like detents at upper edges thereof for detachably securing the supplemental handle means to the handle of the container top wall. 9. A stackable plastic container according to claim 8, wherein the body of said container is formed entirely of blow molded plastic and the supplemental handle means is formed of injection molded plastic. 10. A plastic container comprising: a container body having walls defining a receiving space and an opening for filling and emptying thereof; wherein a top wall is provided with a pair of spaced upwardly projecting top wall portions, a single bar-type handle extending centrally, as a unitary part of said container, from a first of said top wall portions to a second of said top wall portions, and a central portion extending across said top wall, between said projecting top wall portions, at a position below said handle so as to form a hand opening; and wherein a rigid supplemental handle means is provided that is sized and shaped for insertion through said hand opening and for detachable engagement with said single, bar-type handle of the container top wall, said supplemental handle means having a pair of bar-type handle portions, laterally spaced from each other and interconnected by crosspieces, notch means in the crosspieces for receiving the unitary central handle, and securing means for retaining the unitary handle within the notch means, whereby the container is convertible from a single handle container to a triple handle container. 11. A stackable plastic container according to claim 10, wherein the handle portions of the supplemental handle means are interconnected at each of opposite ends thereof by said crosspieces, and wherein said notch means comprises a centrally positioned notch in each of said crosspieces for engagingly receiving the bar-type handle of the container top wall. 12. A stackable plastic container according to claim 11, wherein, as said securing means the notches of the crosspieces have nub-like detents at upper edges thereof for detachably securing the supplemental handle means to the handle of the container top wall. 13.
