    专利说明:

    The invention relates to a dosage technique and can be used in aerosol packages.
    The aim of the invention is to improve the dosing accuracy of sediment-prone active substances.
    Fig, 1 shows the proposed device, a general view; figure 2 - the same option; on fig.Z - the same, option.
    The device consists of a housing 1 having an inlet 2, mounted in the housing 1 of the valve 3 with an outlet 4, and a trap of components deposited in the liquid, mounted with a gap between the wall of the aerosol container and the outer surface of the housing consisting, for example, of a funnel-shaped element 5 mounted on the outer surface of the housing 1 with a smaller base towards the entrance channel 2, the plate 6, mounted under the funnel-shaped element 5, and the annular element 7, located under the plate 6, with This last has an annular flange 8, which is located parallel to the housing 1 in the direction of the bottom of the aerosol container.
    The catcher of the components deposited in the liquid may have a cup-shaped form 9, facing a closed surface with a protrusion 10 formed on it, made in the form of a truncated cone, towards the inlet channel. The catcher of the components deposited in the liquid may be in the form of a V-shaped element with a leg 11, and on the case 1 an additional leg is attached to the leg 11 by means of a stepped plate 13.
    The aerosol container 14 has an inner wall 15, and the housing 1 has an outer wall 16, while between the inner wall 15 and the funnel-shaped element 5 there is a gap 17 of 0.1-0.5 mm, and between the inner wall 15 and the inner wall 18 of the cap 19 the gap is 0.1-2.0 mm.
    The device works as follows.
    In the operating position of the aerosol container 14, the components deposited in the liquid move down to the inlet channel 2 and are captured by the collector of the components deposited in the liquid.
    In Fig. 1, the components are captured by a funnel-shaped element 5 mounted on the outer surface of the housing 1 with an annular gap 17 of 0.1-0.5 mm from the inner wall 15 and a plate 6 with a shoulder 8 located under the funnel-shaped element 5 and covering
    body 1 with a gap of 0.1-2.0 mm between the inner wall 15 of the container 14 and the inner wall 18 of the cap 19. The ratio of the areas of the annular gap 17 to the transverse
    The cross section of the aerosol container 14 is 1: 100-1: 10, in particular 1: 50-1: 25.
    In the embodiment (FIG. 2), the precipitated components are retained by the catcher having a bowl-shaped form 9, with a protrusion 10 made in the form of a truncated cone.
    In the embodiment (FIG. 3), the deposited components are retained by the catcher having the shape of a V-shaped element with
    leg 11, displaced in the direction of the inlet channel 2 relative to leg 12, mounted at a distance of 0.1-2.0 mm from the inner wall 15 of the container 14.

    Claims (4)
    [1]
    1. A metering device housed in an aerosol can cap, comprising a housing having an inlet channel, and
    a valve mounted in the housing with an outlet, characterized in that, in order to improve the dosing accuracy of the sediment-prone active substances, it is provided with a catcher
    components deposited in a liquid, mounted with a gap between the wall of the aerosol container and the outer surface of the housing.
    [2]
    2. The device according to claim 1, wherein the catcher of the components deposited in the liquid consists of a funnel-shaped element mounted on the outer surface of the body with a smaller
    the base in the direction of the inlet channel, the plate mounted under the funnel-shaped element on the housing, and the annular element located under the plate, while the latter has
    an annular collar, located parallel to the body in the direction of the bottom of the aerosol container, with a diameter greater than the diameter of the larger base of the funnel element.
    [3]
    3. The device according to claim 1, of which is that the trap of the components precipitating in the liquid has a cup-like shape, facing the closed surface with the formation of a protrusion on it,
    made in the form of a truncated cone, in the direction of the inlet channel of the housing.
    [4]
    4. The device according to claim 1, of which is that the catcher of the components deposited in the liquid has the shape of a V-shaped element with a leg, and on the case
    the additional leg is strengthened, at the same time the latter is connected to the leg of the V-shaped
    element through a stepped plate.
