PURPOSE: To simplify the structure of a household dispensing device for viscous material by arranging a spring between the apex of a housing and a piston of the device described above and opening a nozzle to extrude the viscous material via a tube.
CONSTITUTION: A pump 11 of a handheld type rotatably having the nozzle 13 via a ball 12 at its apex has the tube 20 arriving at the bottom through the apex at the center of a container body 15 consisting of a synthetic resin, such as polypropylene. A piston 17 freely slidable along the outer peripheral surface of the tube is arranged and a compression spring 19 is interposed between the piston 17 and the apex of the container body 15. Next, the viscous maternal (cheese, cream or the like) M is packed in the container body 15 and the piston 17 is pushed up. The lower open end of the container body 15 is then sealed by a base part cover 16. When an accepting part 13c and the upper aperture 20a of the tube 20 are mated by tilting the nozzle 13, the packed viscous material M is extruded by the energizing force of the compression spring 19. The structure is thus simplified.
