Low profile pump and lid assembly for a stackable container

摘要

A pump (10) and tank lid (20) assembly. The pump is of a low-profile, lightweight design to enable it to cooperate with the lid so that a relatively thin-walled tank can support its weight. In addition, the low-profile design allows the pump to remain attached to the top of the tank (150), even during shipping and stacking of the tanks. Projections (180,190) formed either in the tank or on a frame that surrounds the tank extend beyond the dimensions of the pump (10). The projections allow stacking of fluid material containing tanks so that during tank stacking, adequate clearance is formed between the top of the pump in a lower tank and the bottom of an upper tank.
