Abstract
A system is provided for securing together a container having an opening and a finger-operable pump. One form of the system includes a mounting flange on the pump and a support structure in the container for receiving the flange in a snap-fit or press-fit engagement. In another form, the pump mounting flange is heat bonded to the container with a liner that includes at least two layers of a heat-weldable plastic around at least one interposed layer of substantially electrically conductive metal which can be heated with induction heating. The container can be threaded, and a threaded collar can be screwed onto the container. The collar can have an abutment surface for facing the pump actuator, and the collar can be screwed up or down on the container to establish a selected distance between the collar abutment surface and the pump actuator so as to define the stroke length of the pump.
