Definitions

  • the present invention relates to a valve acting section (stem hole) by which an operation mode setting operation of an aerosol-type product is used to shift from the previous closed state to an open state to inject the contents in a container body to an outer space region and a contents passage section in an invertible use mode communicating with this.
  • the invention relates to an invertible valve mechanism in which the contents passage section is composed of an upright inflow passage and an inverted inflow passage that are continuous in a single straight line-form and a shared invertible passage providing the communication from these common outflow holes to a valve acting section and in which a free fall-type moving valve is provided at a predetermined position of the inverted inflow passage.
  • This moving valve is configured so that the inverted inflow passage is set in a shutoff state when the invertible valve mechanism is upright so as to prevent the vaporized gas flowing in the upper part of the container body from entering the upright inflow passage or the shared invertible passage.
  • the moving valve may be a ball valve for example.
  • the present invention provides an invertible valve mechanism for which the separation relation between this moving valve and the common outflow hole is considered for example to suppress the "gas entrainment" phenomenon of the vaporized gas in the contents to block the so-called intermittent injection of the contents caused by this so that the smooth and continuous injection state can be secured.
  • the "gas entrainment” phenomenon is caused, during the upright operation of the invertible valve mechanism, when the inverted inflow passage in the moving valve that should be shut off from the shared invertible passage is displaced in the "dancing" state in an up-and-down direction due to the strength of the contents flowing from the upright inflow passage.
  • the "upper” and “lower” directions around the respective components of the invertible valve mechanism show the upper and lower positions in the upright state in Fig. 1 to Fig. 2 .
  • the terms “upstream” and “downstream” are not included in the scope of the definitions of the upper and lower positions.
  • the up-and-down directions in the respective drawings are also denoted as a "longitudinal” direction and the left-and-right direction is denoted as a "lateral" direction as required.
  • the above-described aerosol-type invertible valve mechanism has been conventionally used that consists of the upright inflow passage, the inverted inflow passage, and the shared invertible passage, and this inverted inflow passage includes a free fall ball valve to switch the upright injection/inverted injection (see Patent Publication 1).
  • Patent Publication 1 Japanese unexamined patent application publication H6-199376
  • DE 34 33 496 A1 relates to a valve which an be operated in an upside down position for distribution of a pressurized liquid.
  • a valve having a valve body which is closed on one side and whose blind end region is penetrated by an eccentric bore for the liquid supply, which bore opens out in an annular, axial groove of an attachment part. This groove communicates via an eccentric channel with a chamber in which an axial immersion tube and a passage open out, which passage is normally closed by a ball which is freely movable in a ball cage, but is connected via an aperture to the external space of the attachment part when the valve is turned upside down.
  • US 4,723,692 A relates to a spray value arrangement.
  • a spray valve assembly for an aerosol container comprising a valve housing which can be sealingly fixed into the top of the container, the housing defining a main passage for the throughflow of the contents of the container, a valve stem within the housing forming the main valve, an immersion pipe extending from the main passage in the housing, a secondary passage communicating the container and the main passage in the housing for the throughflow of the contents of the container when the container is inverted, an auxiliary valve disposed between the secondary and main passages, which auxiliary valve is disposed eccentrically within the valve housing.
  • GB 2 019 497 A relates to a spray valve for an aerosol can.
  • the ratio of the cross- sectional area of the aperture leading into the valve chamber, to the cross-sectional area of the dip tube nipple passage is between 1.1 and 1.5.
  • the cross-sectional area of the aperture is 1.5 to 2.0 times greater than the nipple passage area.
  • the upper end of the common outflow hole is separated from the lower end of the moving valve in the up-and-down direction by a distance of 1.2mm for example.
  • the moving valve has been provided in the very vicinity of the upper part of the common outflow hole in the inverted inflow passage that is shared by the upright inflow passage and the inverted inflow passage.
  • the moving valve tends to be in the "dancing" state due to the strength of the contents flowing from the upright inflow passage.
  • the invertible valve mechanism of the present invention pays attention on not the size or material of the moving valve but on the position of the moving valve in order to eliminate the intermittent injection state of the contents due to the "gas entrainment" in the invertible valve mechanism in which the moving valve is provided on the extended straight line at the contents outflow side of the upright inflow passage.
  • the moving valve that shuts off the inverted inflow passage from the downstream-side shared invertible passage in the upright operation mode is provided at a position separated from the upper end of the common outflow hole for the upright inflow passage and the inverted inflow passage by a distance of at least 3.5mm or more desirably a distance of 3.7mm or more.
  • This common outflow hole also functions as an inflow section to the shared invertible passage.
  • the moving valve to switch ON or OFF the inverted inflow passage is provided at a position upwardly separated from the common outflow hole for the upright inflow passage and the inverted inflow passage by a predetermined distance to thereby block the occurrence of the "dancing" state in which the moving valve in the upright operation mode is displaced by the strength of the upwardly-flowing contents.
  • This predetermined distance is "at least 3.5mm or more desirably a distance of 3.7mm or more" as described above.
  • the moving valve is provided at a position at the upper side of the common outflow hole separated by a distance about three times longer than the conventional distance of "1.2mm".
  • the present invention solves the above disadvantage using an invertible valve mechanism described below.
  • the present invention provides an invertible valve mechanism consisting of the above configuration and an aerosol-type product including this.
  • the present invention blocks the occurrence of the "dancing" state of the moving valve in the upright operation mode to prevent the "gas entrainment” of vaporized gas in the contents, thus stabilizing the continuous injection state of the contents.
  • the common outflow hole is separated, without requiring a particular change of the size of the moving valve itself or the material thereof, from the moving valve by such a distance that prevents the strength of the flowing injection contents from acting on the moving valve, thus providing the efficient use of the components of the invertible valve mechanism.

  • the letter C shows a shared invertible passage starting from the common outflow hole for the upright inflow passage A and the inverted inflow passage B.

  • the ball valve 7, the mounting cup 9, and the container body 10 are made of metal (e.g., stainless).

  • the aerosol-type invertible valve mechanism shown in Fig. 1 to Fig. 4 is basically characterized in that the vertical spacing L in the upright state between the upper end of the common outflow hole 6f of the upright inflow passage A and the inverted inflow passage B and the lower end of the ball valve 7 is set to at least 3.5mm or desirably 3.7mm or more.
  • this vertical spacing L is increased to have a value larger than a conventional value (e.g., 1.2mm) so as to reduce the influence on the ball valve 7 due to the strength of the contents upwardly flowing from the upright inflow passage A in the upright operation mode.
  • a conventional value e.g., 1.2mm
  • This reduction of the influence on the ball valve suppresses the vaporized gas in the upper part of the container body in the upright state from passing the ball valve to flow from the inverted inflow passage B to the shared invertible passage C. Specifically, this eliminates the "gas entrainment" of the vaporized gas in the contents in the shared invertible passage C.
  • the downward motion of the stem 2 changes the shape of the inner end of the stem gasket 3 to a "bow"-like shape, thereby cancelling the previous valve closed state to the lateral hole 2a.
  • This valve cancellation allows, as shown in the drawing, the contents in the lower space region of the container body 10 to pass through the upright inflow passage A and the shared invertible passage C to be injected to the outer space region through the well-known button injection opening.
  • the contents in the container body flow through the path composed of "the dip tube 8-the common outflow hole 6f-the annular space region 4h-the longitudinal penetration section 4g-the inner space region of the upper sheath-like section 4a-the lateral hole 2a-the button interior passage 1a".
  • the vertical spacing L extending from the upper end of the common outflow hole 6f to the lower end of the ball valve 7 is set to at least 3.5mm or more desirably 3.7mm or more.
  • the common outflow hole 6f separated from the ball valve 7 in the up-and-down direction as described above can substantially prevent the ball valve 7 in the upright operation mode from "dancing" due to the strength of the contents upwardly flowing from the upright inflow passage A.
  • this spacing can prevent a situation where the vaporized gas enters the shared invertible passage C via the ball valve 7 in the “dancing" state to cause the "gas entrainment" in the contents.
  • This suppression of the "gas entrainment" provides the contents injection to the outer space region not in a pulsating flow-like intermittent injection state but in a stable continuous injection state.
  • the following table 1 shows the result of the examination of this continuous injection. Specifically, the examination of the injection state was performed based on the total of 11 experimental models prepared to have the vertical spacing L between the upper end of the common outflow hole 6f and the lower end of the ball valve 7 so that the vertical spacing L is changed from 3.0mm to 4.0mm by an increment of 0.1mm.
  • L (mm) 3.0-3.4 3.5 3.6 3.7 3.8 3.9
  • the occurrence of the "gas entrainment” was examined by visually monitoring the flow of the contents injected to the outer space region via the valve acting section in the open state (the lateral hole 2a and the stem gasket 3). Specifically, the contents injected to the outer space region were visually monitored with regard to whether the contents formed a stable continuous flow or a pulsating flow-like intermittent flow.
  • the pulsating flow-like intermittent injection state of the "gas entrainment" may be sufficiently visually monitored by general users.
  • the examination result shows, as shown in the table 1, that the vertical spacing L having a different size shows the following different result.
  • the vertical spacing L from the upper end of the common outflow hole 6f to the lower end of the ball valve 7 is set to at least 3.5mm or more desirably 3.7mm or more.
  • the longitudinal space region 4f was used that had a height of 6.3mm in the up-and-down direction and a diameter of 3.4mm.
  • the upper central cylindrical section 6b was used that had a height of 1.0mm in the up-and-down direction and the inner diameter of 2.3mm.
  • the cylindrical body 6c was provided between the upper central cylindrical section 6b and the dip tube 8.
  • the cylindrical body 6c consisted of a pair of opposed flat surfaces having an interval of 2.8mm and a pair of opposed arc curved surfaces having an inner diameter of 3.3mm therebetween.
  • Each of the opposed flat surfaces included therein a common outflow hole 6f having a lateral length of 1.1mm and an inner diameter of 1.5mm.
  • the annular space region 4h had a lateral interval of 0.425mm.
  • the longitudinal penetration section 4g was used that had a height in the up-and-down direction of 6.7mm, the cross section width of 1.0mm, and a cross section having a depth of 0.6mm.
  • the cylindrical body 6c and the annular space region 4h have the direction in the up-and-down direction that is different depending on each experimental model set depending on the value of the vertical spacing L from the upper end of the common outflow hole 6f to the lower end of the ball valve 7.
  • This valve cancellation causes, as shown in the drawing, the contents in the upper space region of the container body 10 in the upright state to be sent through the inverted inflow passage B and the shared invertible passage C, thereby injecting the contents to the outer space region through the well-known button injection opening.
  • the contents in the container body are allowed to flow through the path of "the peripheral face opening 4e-the longitudinal space region 4f-the inner space region of the upper central cylindrical section 6b-the inner space region of the cylindrical body 6c-the common outflow hole 6f-the annular space region 4h-the longitudinal penetration section 4g-the inner space region of the upper sheath-like section 4a-the lateral hole 2a-the button interior passage 1a".
