Container, handle attachment and method

A plastic container used for holding fluid material with an attachable handle is provided. The container includes a body, a plurality of walls, a spout, an attachable handle and a sliding structure. The spout is a hollow, cylindrical portion that extends from an opening in one of the walls. The cylindrical portion is configured to insert or remove the fluid material from the container. The attachable handle includes a rail structure that further includes a pair of non-parallel offset rails and a latch. The latch has a latching surface that is located at the ends of the offset rails farthest from each other. The slide structure includes a generally rectangular projection. The projection further includes a pair of non-parallel offset grooves and a latching surface. The latching surface is located where the grooves are farthest from each other. The offset grooves are adapted to mate with the offset rails and are fully engaged by the offset rails when the latch is engaged with the latching surface.
