Definitions

  • the present invention relates to a gas charge mechanism of an aerosol type dispenser for spraying contents in a constant stored chamber in a housing according to the action of a valve stem and a seal member, more particularly, to a gas charge mechanism in order to reduce the pressure of the charge gas by charging gas through a passage between the valve stem and the seal member formed by shifting the seal member apart from the stem according to the gas pressure from the valve stem.
  • Compressed gas such as nitrogen gas and carbonic acid gas are used for spraying contents in a container.
  • compressed gas are not liquefied in the normal temperature, they are not mixed with the contents.
  • the contents are sprayed by the pressure of the compressed gas.

  • the housing 34 and the annular collar 32 is fixed firmly through the gasket 33.
  • the gas is forced to pass through the aperture 33(a) between the gasket 33 and the annular collar 32. Consequently, high gas pressure has to be applied to the container 40. This high pressure causes the housing 34 gotten out of the annular collar 32 and other parts broken.
  • aerosol type dispensers disclosing the features of the preamble of appending claim 1 are known, e.g., from US 4,220,265, FR-A-2,492,778 and US 3,292,666.
  • the object of the present invention is to reduce gas pressure by making a passage between a constant stored chamber and an upstream space thereof in a container by moving the seal member for forming a constant stored chamber apart from a stem by gas charge pressure.
  • the aerosol type dispenser comprises a seal member which can be apart from a valve stem by the gas charge pressure.
  • This seal member can make a passage communicating a constant stored chamber with the upstream side of the constant stored chamber so as to pass the gas. Since the gas is charged through the passage, the gas charge pressure can be reduced.
  • the seal member is formed a cylindrical shape and provides a first brim to shift the seal member itself to the state with the gas charge pressure.
  • a first brim part of the seal member receives enough gas pressure to shift the seal member and make a passage communicating a constant stored chamber with the upstream side of the constant stored chamber.

  • 16(f) shows a lower end of the skirt
  • 16(g) shows a way between the seal member 16 and the stem 11 opened for introducing contents from a container to the constant stored chamber 14(c)
  • 14(a), 16(g') shows a
  • valve stem 11, the housing 14, the piston 18 and the bush 21 are made of POM(Polyacetal) and so on.
  • the seal members 16, 17 are made of LDPE(Low Density Polyethylene) and so on.
  • the seal member 16 for opening and closing the way 16(g) between the constant stored chamber 14(c),14(a) and the space 14(f) is equipped separately from the housing 14.
  • the seal member 16 with the brim 16a is a cylindrical shape.
  • the seal member 16 is urged upwardly by means of the spring 19.
  • the brim 16(a) provides the wide upper face 16(b) for receiving gas charge pressure and forms the hole 16(c) for passing through the contents (see FIG.4).
  • the skirt 16(d) provides the annular convex portion 16(e) for contacting firmly with the peripheral surface of the stem 11 when the stem 11 moves downwardly.
  • the seal member 16 is urged by means of the spring 19 upwardly both in the mode in nonuse and in use, and acts in the same manner as the seal valve provided in the conventional aerosol type dispenser.
  • the stem 11 in the mode in nonuse, the stem 11 is moved upwardly by urging force of the spring 15. Therewith, the side hole 11(b) is positioned above the gasket 12. The seal member 16 is also moved upwardly by urging force of the spring 19. Therefore, the way 16(g) between the stem 11 and the seal member 16 is opened.
  • the contents in the container 22 is allowed to flow in the constant stored chamber 14(c), 14(a) through the route of the dip tube 20 - the space 14(f) - the way 16(g) - the pass way 16(c) - the pass hole 14(e) according to the pressure of the compressed gas in the container 22.
  • a valve actuator (not shown) is pressed, the stem 11 moves downwardly against the urging force of the spring 14(a). At this time, as the seal member 16 keeps upward position by the urging force of the spring 19, the peripheral surface of the stem 11 contacts firmly with the annular convex portion 16(e) of the seal member 16, then the way 16g is closed. Consequently, the contents cannot be flown from the space 14(f) to the downstream part of the constant stored chamber 14(a).
  • the pressure in the constant stored chamber 14(a), 14(c) is lowered, then the piston 18 is moved upwardly according to the pressure of the compressed gas in the container 22 until the annular flat portion 18(c) of the piston 18 contacts the stopper 14(d). Therefore, the contents in the constant stored chamber 14(a),14(c) are sprayed outside through the route of the upstream part of the constant stored chamber 14(c) - the pass way 16(c) of the seal member 16 - the pass hole 14(e) - the downstream part of the constant stored chamber 14(a) - the side hole 11(b) of the stem 11 - the spraying way 11(a).
  • FIG.2 illustrates a gas charge mode of aerosol type dispenser 1.
  • compressed gas is charged into the container 22 through the route of the opening 13(a) - the aperture 12(a) between the stem 11 and the gasket 12 - the downstream part of the constant stored chamber 14(a) - the pass hole 14(e) - the passage 16(g') between the seal member 16 and the stem 11 - the space 14(f) - the dip tube 20.
  • the upper face 16(b) of the seal member 16 Since the upper face 16(b) of the seal member 16 is wide, the upper face 16(b) can receive the pressure of the compressed gas fully- The pressure received on the upper face 16(b) surpasses the urging force of the spring 19, then the seal member 16 moves downwardly while the lower end 16(f) is guided by the inner surface 18(a) of the piston 18. As a result, the passage 16(g') between the seal member 16 and the stem 11 is opened.
  • the seal member 16 is separated from the housing 14, and the wide upper surface receives fully pressure of gas charge, therefore the seal member 16 moves downwadly than the pressed(low positioned) stem 11. As a result, the enough passage 16(g') for allowing gas to pass through is opened between the seal member 16 and the stem 11.
  • the seal member 16 Since the lower end 16(f) of the seal member 16 is guided by the inner surface 18(a) of the piston 18, the seal member can move upward smoothly without inclining.
  • FIG.3 illustrates the gas charge mode of the aerosol type dispenser 2 providing the bendable seal member 17 separately from the housing 14.
  • the brim 17(a) of the seal member 17 which is different from the brim 16(a) of the seal member 16 is comprised of the outer edge 17(b) and the narrow bendable portion 17(c).
  • the pass way 17(d) for the contents is formed between the bendable portion 17(c).
  • the seal member 17 is urged upwardly by means of the spring 19 fixed on the outer edge 17(b).
  • the compressed gas is charged into the container 22 through the route of the opening 13(a) - the aperture 12(a) between the stem 11 and the gasket 12 - the downstream part of the constant stored chamber 14(a) - the pass hole 14(e) - the passage 17(h) between the seal member 17 and the stem 11 - the space 14(f) - the dip tube 20, in the same manner as the aerosol type dispenser 1 shown in FIG.2.
  • the bendable portion 17(c) of the seal member 17 recovers initial shape with elasticity of itself.
  • FIG.4(A) and FIG.4(B) illustrates the upper face of the seal member 16 shown in FIG.1 and FIG.2 and the upper surface of the seal member 17 shown in FIG.3.
  • the upper face 16(b) for receiving gas charge pressure is wider than the upper face of the bendable portion 17(c)(for receiving gas when the gas is charged). Therefore, when the seal member 16 and the seal member 17 receive the same pressure/the unit area of gas, whole pressure applied on the seal member 16 is higher than it on the seal member 17. Consequently, the seal member 16 itself moves downwardly.
  • the bendable portion 17(c) of the seal member 17 is narrower than each section of the upper face 16(b) of the seal member 16, when the seal member 17 receives gas charge pressure, the bendable portion 17(c) is bent as shown in FIG.3.
  • the each gas charge pressure in the aerosol type dispenser 1 with the seal member 16 and the aerosol type dispenser 2 with the seal member 17 was 9kg force.
  • the seal member 16, 17 may be formed in any shape so as to open enough passage between the stem 11 for charging gas by gas charge pressure.
  • seal member 16 of FIG. 3 may be formed integrally with the housing, and any part thereof is transformed by gas charge pressure.
  • a seal member may be formed separately from the housing, the seal member itself moves downwardly with bending the part such as a brim thereof by gas charge pressure.
  • the upper face 16(b) of the seal member 16 and the bendable portion 17(c) of the seal member 17 may be formed with bendable material so as to be bent by the gas charge pressure.
