发明名称 Flexible eduction tube for hand dispenser
摘要 An apparatus and method is disclosed for an improved flexible eduction tube for discharging a liquid product from a container with a dispensing mechanism comprising a mixture of a flexible material with a dense filler material distributed within said flexible material to provide a specific gravity greater than the liquid product within the container for enabling an input aperture of the eduction tube to remain below the level of the liquid product within the container when the container is tipped from a vertical orientation. In another embodiment of the invention, the eduction tube comprises a flexible material and rigid means for providing a non-flexible eduction tube prior to insertion of the eduction tube within the container and for providing a flexible eduction tube upon contact with the liquid product within the container.
