- 7. A dispenser according to claim 1, wherein said head fitting includes two spaced apart walls, and wherein said actuating lever comprises a plate-like element having two wings which extend at right angles to the plate-like element, said wings being set mutually apart to fit in between and closely to said walls of the head fitting, the wings and the walls being respectively provided with said projecting pins and pin seatings, said pins being received in said pin seatings.
- 8. A dispenser according to claim 7, wherein each pin seating includes a semicircular opening opened toward the bottom wall of the container.
- 9. A dispenser according to claim 7, wherein each pin seating comprises a semicircular opening opened toward the bottom wall of the container and including an incline for guiding the respective projecting pin whereby each of the pins, during the assembling, will snap fit into its respective pin seating.
- 10. A dispenser according to claim 7, wherein said cam profile of the actuating lever is formed on at least one of the wings.
- 11. A dispenser of generic paste products and specifically toothpaste, comprising a cylindrical container having a longitudinal axis, a head fitting at the upper end of the container, a bottom wall arranged to slide sealingly in the container one way toward the head fitting, a pumping member mounted in the container close against the head fitting, a conduit with a free end and with an opposed end associated with the pumping member, an actuating lever for moving the pumping member, projecting pins projecting from the lever along a pivot axis perpendicular to the longitudinal axis, said pivot axis being fixed relative to the container, said lever being angularly displaceable around the pivot axis of the cylindrical container from a home position to a paste delivery position, pin seatings formed in the head fitting for receiving said projecting pins, a tubular spout having an inlet mouth and an outlet mouth being fixed to the head fitting, a closure eave formed integrally with the actuating lever and extending to cover the outlet mouth with the lever in the home position thereof, said actuating lever being provided with a cam profile which is spaced out of contact from said free end of the conduit when the lever is in its home position and which is operatively engaged with the same said free end of the conduit upon an angular displacement of the lever at the end of which displacement the eave uncovers the outlet mouth of the spout, said conduit being connected to said tubular sprout in continuation thereof and sliding sealingly to said tubular sprout at the same end as the inlet mouth, said pumping member comprising a flexible annular membrane having an outward edge held axially to the cylindrical container and an inward edge connected to the conduit.
- 12. A dispenser according to claim 11, wherein said projecting pins are integrally formed with the lever.
- 13. A dispenser according to claim 11, wherein said conduit is integrally formed with the flexible annular membrane of the pumping member.
- 14. A dispenser according to claim 11, wherein the head fitting is formed integrally with the cylindrical container.
- 15. A dispenser according to claim 11, wherein each of the conduit and the flexible annular member has a wall thickness, the wall thickness of the conduit being greater than the wall thickness of the flexible annular membrane.
- 16. A dispenser according to claim 11, wherein the cylindrical container includes an inner circumferential protuberance for axially restraining the outward edge against movement toward the bottom wall.
- 17. A dispenser according to claim 11, wherein said head fitting includes a two spaced apart walls and wherein said actuating lever comprises a plate-like element having two wings which extend at right angles to the plate-like element, said wings being set mutually apart for fitting between and closely to said walls of the head fitting, the wings and the walls being respectively provided with said projecting pins and pin seatings, said projecting pins being received in said pin seatings.
- 18. A dispenser according to claim 17, wherein each pin seating includes a semicircular opening opened toward the bottom wall of the container.
- 19. A dispenser according to claim 17, wherein each pin seating comprises a semicircular opening opened toward the bottom wall of the container and including an incline for guiding the respective projecting pin, whereby each of the pins, during the assembling, will snap fit into its respective pin seating.
- 20. A dispenser according to claim 17, wherein said cam profile of the actuating lever is formed on at least one of the wings.
