Definitions
- the present invention relates to a dispenser for discharging fluid contents such as shampoo, detergent, cosmetics stored in a container, more particularly, to a dispenser for providing a suction mechanism and a shutoff member so that the fluid residue present in a discharging aperture nearby after discharge are prevented from dripping, hardening, deteriorating.
- the present invention also relates to a dispenser for preventing the contents from leaking or dripping when the container is fallen down.
- Japanese publication NO.8-169462 discloses a pomp type liquid dispenser for preventing fluid residue from dripping from a nozzle after discharging the contents.
- Fig. 7, Fig. 8 and Fig. 9 illustrate the pomp type liquid dispenser.
- Fig. 7 illustrates a mode in nonuse
- Fig. 8 illustrates a mode in use
- Fig. 9 illustrates a transition state from the mode in use to the mode in nonuse after releasing an actuator.

- 41 shows an actuator
- 41(a) shows a nozzle
- 41(b) shows a nozzle aperture
- 41(c) shows a pass way
- 42 shows a valve stem fixed firmly with the actuator 41 so that it moves upwardly and downwardly with the operation of the actuator 41
- 42(a) shows a side hole for passing contents
- 42(b) shows an annular convex portion
- 42(c) shows a reception for receiving a seal member 44
- 42(d) shows an annular flange
- 43 shows a housing
- 43(a) shows a storage chamber
- 43(b) shows an opening for drawing air in the decompressed container 52 after discharge
- 44 shows a seal member urged upwardly against the valve stem 42
- 44(a) shows an upper end of the seal member 44
- 44(b) shows a lower end of the seal member 44
- 45 shows a member for screwing with the actuator 41
- 45(a) shows a skirt for receiving the seal member 44
- the valve stem 42 is urged upwardly by means of the spring 50.
- the housing 43 includes the contents flown from a container, according to the previous operation. Since the upper end 44(a) of the seal member 44 contacts firmly with the skirt 45(a) of the engaging member 45 and the lower end 44(b) contacts firmly with the reception 42(c) of the valve stem 42, the side hole 42(a) for communicating the housing 42 and the valve stem 42 is shut.
- valve stem 42 moves upwardly, at first the upper ball valve 48 is closed. Then the lower ball valve 49 is opened so that the contents flows in the housing 43. Finally, the lower ball valve 49 is closed. The fluid residue present in the nozzle 41(a) and the passage 41(c) and so on after discharge are drawn into the valve stem 42 and housing 43 until the upper ball valve 48 is closed.
- valve stem 42 After the seal member 44 moves upwardly relatively to the valve stem 42 until the upper end 44(a) contacts firmly with the skirt 45(a) of the member 45, only the valve stem 42 moves upwardly.
- the valve stem 42 gets back to be a nonuse position, the lower end 44(b) of the seal member 44 contacts firmly with the reception 42(c) of the valve stem 42, therewith the side hole 42(a) is shut and the way from the storage chamber 43(a) to the valve stem 42 is closed.
- the conventional pomp-type liquid dispenser keeps the side hole for communicating the valve stem with the housing opening after releasing the actuator in order to draw the fluid residue present in the nozzle or the pass way into the housing through the valve stem so as to prevent dripping from the nozzle aperture.
- the contents in the valve stem, the nozzle and the pass way, which are positioned in the downstream of the side hole of the valve stem may be leaked or dripped.
- the fluid residue present in the nozzle contacts with the air so that they may be deteriorated or hardened. This causes a nozzle blockade, consequently the contents cannot be discharged.
- the dispenser provides a valve stem, a housing, an upper valve in the valve stem and a lower valve in the housing.
- the upper valve When the upper valve is opened by actuation, the contents stored in a chamber between the upper valve and the lower valve are discharged from a discharging aperture.
- the dispenser configures a linear passage between the upper valve and the lower valve formed by having a mouth at housing side portion of the valve stem, and a shutoff member for closing the discharging aperture with urging force and for opening the discharging aperture against the urging force according to the actuation.
- a passage between an upper valve and a lower valve is configured to be linear, the fluid residue present in the discharging aperture nearby or the discharging pass way after discharge can be sucked smoothly and certainly into a housing. Therefore, dripping from a discharging aperture is prevented.
- the discharging aperture is closed by the shutoff member with urging force compulsorily except for actuation, the contents are prevented from leaking or dripping when a container is fallen down and the fluid residue present in a discharging aperture nearby or a discharging pass way are prevented from deteriorating and hardening.
- a seal member for contacting with the inner surface of the housing is combined with the valve stem.
- valve stem and the contacting member are substantially configured to be in one part, the number of the parts, for example a spring for urging the seal member can be reduced and the assembly thereof is simplified.
- the seal member for contacting with the inner surface of the housing is integrally formed with the valve stem.
- the seal member and the valve stem are in one part, the number of the parts can be reduced and the assembly thereof is simplified.
- the seal member is configured to make an opening, which is formed in said housing in an active state in order to draw air into a container room around the housing.

- 10(b) shows an inner surface of the cover
- 11 shows a cylindrical head
- 11(a) shows a longitudinal discharging pass way
- 11(b) shows a lateral discharging pass way
- 11(c) shows a receiving portion for restricting upward movement of the upper ball valve
- 12 shows a tubular tip
- 12(a) shows a discharging aperture
- 13 shows a shutoff member installed movable in the cylindrical head
- 13(a) shows a front end
- 13(b) shows a lip sealingly moves against the head
- 13(c) shows a tapered portion for corresponding to the operation portion
- 13(d) shows a back end
- 14 shows a spring for urging the shutoff member in the direction of the aperture 12(a)
- 15 shows an upper ball valve
- the shutoff member 13 is formed so that the front part comprising the front end 13(a), and the back part comprising the lip 13(b) and the back end 13(d) are fixed firmly.
- the seal portion 18(g) and the seal member 19 move guided by the inner surface of the housing 17 when the valve stem 17 moves. Also, the seal portion 18(g) and the seal member 19 sealingly slide against the inner surface of the housing 17.
- the pomp type dispenser 1 is comprised of the followings, that is, the shutoff member 13 for opening or closing the discharging aperture 12(a) of the tip 12, the head 11 which is movable upwardly and downwardly against the cap 22 with holding the tip 12 and the valve stem 18, the cover 10 which the taper-shaped operation portion 10(a) is formed and is movable upwardly and downwardly against the head 11, the valve stem 18 which the seat 18(a) and the rib 18(b) for the upper ball valve 15 are formed and the seal member 19 is fixed, the housing 17 which the storage chamber 20 and the seat 17(b) for the lower ball valve 16 are formed and guides the seal portion 18(g) or the seal member 19 when they move upwardly and downwardly, and the cap 22 which the housing 17 is fixed and maintains the head 11 and the cover 10 in the state that the head 11 and the cover 10 are movable upwardly and downwardly.
- the whole body of the shutoff member 13 is urged in the direction that the aperture is closed by means of the spring 14.
- the whole peripheral surface of the lip 13(b) contacts with the inner surface of the head 11.
- the tapered portion 13(c) contacts with the operation portion 10(a) of the cover 10.
- the seal member 19 is fixed firmly with the valve stem 18 so that the rim 19(c) is engaged with the inner rim 18(e), and the peripheral upper end 19(a) and the peripheral lower end 19(b) contacts with the inner surface of the housing 17.
- the seal member 19 combined with the stem 18 moves upwardly and downwardly with guiding by the inner surface of the housing 17.
- the storage chamber 20 for storing contents means the room surrounded with the lower ball valve 16, the housing 17, the seal member 19, the valve stem 18 and the upper ball valve 15.
- valve stem 18 moves upwardly until the shoulder 18(d) contacts the inner rim 22(a) of the cap 22 by means of the spring 21.
- the storage chamber 20 includes contents which are flown from the container after previous operation. Because after the previous operation the valve stem 18 moves upwardly by means of the spring 21, the pressure in the storage chamber 20 is lowered, therewith the lower ball valve 16 is opened and the contents flow from the container to the storage chamber 20.
- the operation portion 10(a) acts the tapered portion 13(c) of the shutoff member 13 so that the shutoff member 13 moves rightwards.
- the head 11 does not move until the back end 13(d) of the shutoff member 13 contacts the inner surface 10(b) of the cover 10. After the back end 13(d) of the shutoff member 13 contacts the inner surface 10(b) of the cover 10, the head 11 moves downwardly with the cover 10. At this time the valve stem 18 moves downwardly, therewith the pressure in the storage chamber is increased, so that the upper ball valve 15 leaves the seat 18(a) and moves upwardly until it engages the ribs 18(b) and receiving portion 11(c).
- the contents in the storage chamber 20 are discharged from the aperture 12(a) of the tubular tip 12 through the route of the upper room 18(c) of the valve stem 18 - a narrow gap between the ribs 18b and the upper ball valve 15 - the longitudinal discharging pass way 11(a) - the lateral discharging pass way 11(b).
- the seal member 19 is positioned below the opening 17(a), the inside of the container communicates with outside by the route shown (A) through the opening 17(a).
- This pressure decrease makes fluid residue present in the aperture 12(a) nearby, the lateral discharging pass way 11(b), the longitudinal discharging pass way 11(a) and the upper room 18(c) of the stem valve 18 sucked in the storage chamber 20. This suction continues until the upper ball valve 15 contacts the seat 18(a) firmly.
- the route of the longitudinal discharging pass way 11(a) - the upper room 18(c) of the valve stem 18 - the storage chamber 20 is almost linear, the fluid residue present in the aperture 12(a) nearby, the lateral discharging pass way 11(b), the longitudinal discharging pass way 11(a) are effectively sucked in the storage 20.
- the stem valve 18 moves upwardly so that the upper ball valve 15 contacts the seat 18(a), then the pressure in the storage chamber 20 is lowered than the pressure in the container, the lower ball valve 16 leaves the seat 17(b) so that the contents in the container flow in the storage chamber 20.
- the pressure in the container is decreased corresponding to the degree that the contents in the container flows in the storage chamber 20.
- the outside air is drawn through the route shown (A) until the opening 17 is closed by the seal member 19 when the valve stem 18 recovers the position shown in FIG.1. Therefore, the pressure in the container is recovered to be the original state.
- pomp type dispenser 1 Another distinctive feature of the pomp type dispenser 1 is that the shutoff member 13 moves leftwards after releasing the cover 10 by means of the spring 14 so as to close the aperture 12(a) of the tubular tip 12. Since the tapered portion 13(c) of the shutoff member 13 presses the operation portion 10(a), the cover 10 moves upwardly relatively to the head 11 so as to recover the state shown in FIG.1.
- the front end 13(a) of the shutoff member 13 closes the aperture 12(a) of the tubular tip 12, therefore, even when the small quantity of the fluid are remained in the aperture 12(a) nearby, the fluid residue are prevented from dripping, hardening and deteriorating.
- FIG.4, FIG.5, FIG.6 illustrate the another embodiment which the seal member 19 shown and the valve stem 18 in FIG.1 are integrally molded.
- the other components are same as those shown in FIG.1.
- To assemble this dispenser the step for fixing the seal member to the valve stem 18 is needless.
- the cover 10 When the cover 10 is actuated, same as the case shown in FIG.2, the contents in the storage chamber 20 are discharged from the aperture 12(a) of the tubular tip 12 through the route of the upper room 18(c) of the valve stem 18 - the longitudinal discharging pass way 11(a) - the lateral discharging pass way 11(b) (see FIG.5).
- the route through the longitudinal discharging pass way 11(a) - the upper room 18(c) of the stem - the narrow gap between the ribs 18(b) and the upper ball valve 15 -the upper ball valve 15 - the lower ball valve 16 is almost linear without twisted parts. Also the route which the fluid residue move from the valve stem 18 to the housing 17 is not narrowed. Therefore, the fluid residue present in the aperture 12(a) nearby, the lateral discharging pass way 11(b), and the longitudinal discharging pass way 11(a) are easy to be sucked into the storage chamber 20.
- the front end 13(a) of the shutoff member 13 closes the aperture 12(a) of the tubular tip 12, certainly.
