A device suitable for use as a single-piece dual-chambered can of synthetic material has a larger chamber, for holding gasoline a smaller chamber for holding oil, and a thin connecting member arranged between said chambers in the separation plane between the two said chambers and forming part of said chambers. Said device has on its upper side a handle straddling the separation plane and possessing a root that begins on the upper side of said larger chamber. The said connecting member is non-linear along a considerable section of its length. The deviation from the linear is many times greater than the thickness of the connecting member.
