ABSTRACT:
The multi-chamber containers with a dispenser/doser are blow molded as a single integral item. They then are fitted with dip tubes with the dip tube fitment forming a seal in the transition of the container to the dispenser/doser. The dividing walls in the container are continued up into and through the dispenser/doser. A closure with a rotatable contact surface seals the container. The container preform is made by injection molding using an elongated gate pad in one embodiment in another embodiment an arrangement of recesses on the ends of the core projections with a complementary shaped gate pad. The webs of the container are of a thickness so that they flex upon a compression force being applied to the container walls.
