Abstract
A container and pump device is provided that allows interference in pumping action, caused by collapsing of an inner layer of the container during expulsion of fluid from within the container, to be eliminated. The container can be a laminated bottle having a mouth portion, a body, a bottom portion, and at least an inner layer and an outer layer. The pump device includes a suction portion inserted into the bottle and an operable portion exposed to an outside of the bottle. The suction portion is open to a lower end of the pump and includes a rod extending toward the bottom of the bottle. The rod has a cross-section that extends in more than two directions, preferably an I-beam with a centrally intersecting beam. The suction portion, including the rod, creates several fluid communication paths along the I-beam rod from the inner layer to the pump.
