Detailed description of the invention
Fig. 1 is the Conventional aerosol valve totally represented by Reference numeral 10.In FIG, show the valve 10 under total travel, to show before preparation can enter the centre hole of valve rod the flow path of complications around the length of the product formulation outside Compress Spring.
Aerosol valves 10 comprises dip tube 12, valve rod 16, valve rod housing 18, mounting cup 20, sealing member 22 and Compress Spring 32.Valve rod 16 is closed in valve rod housing 18.Valve rod 16 has pair of holes (not shown in figure 1), and the high solids product preparation of pressurization passes through this pair of holes, to enter the centre hole 24 of valve rod 16.Mounting cup 20 is directed and be stabilized on the appropriate location of product by aerosol valves 10.Valve rod 16 is at contact point 26 place contact Compress Spring 32.
Compress Spring 32 applies to upward pressure on valve rod housing 18, and valve rod housing 18 is pressed against on sealing member 22, and sealing member 22 is positioned at the inside of mounting cup 20.Valve rod 16 has the top projecting through sealing member 22 and mounting cup 20, and this top is extruded by customer and sprays product formulation.
When valve rod 16 is pressed by customer and sprayed product, product formulation upwards flows through the inner space of valve rod housing 18 in flow path 30.
As shown in Figure 1, Compress Spring 32 is fully compressed, and each coil of Compress Spring 32 is pushed together, so have little space or do not have space between arbitrary each coil.In the configuration, the coil of Compress Spring 32 serves as the obstruct of Compress Spring inner space, needs product formulation upwards to advance longer path, and almost the complete outside along Compress Spring 32 is through valve rod housing 18.This length and the main flow path 30 of complications increases following possibility, that is: the solid in product formulation is by gathering and block flow path, causes the flowing of product formulation in flow path all slowed down or intercept, causes product bug.
Fig. 2 to Fig. 9 shows the illustrative embodiments of aerosol valves 40 of the present disclosure.With reference to Fig. 2 to Fig. 4, aerosol valves 40 comprises dip tube 42, Compress Spring 44, valve rod 46, valve rod housing 48, mounting cup 50 and sealing member 52.Valve rod 46 is closed in valve rod housing 48.Valve rod 46 has valve rod hole 58, and the product formulation of the high solids content of pressurization passes through valve rod hole 58, to enter the centre hole 54 of valve rod 46.Aerosol valves 40 is located and is stabilized on the appropriate location of product by mounting cup 50.Valve rod 46 contacts Compress Spring 44 at contact point 56.
Compress Spring 44 applies to upward pressure on valve rod housing 48, and valve rod housing 48 is compressed against on sealing member 52, and sealing member 52 is positioned in the inside of mounting cup 50.Valve rod 46 has the top projecting through sealing member 52 and mounting cup 50, and this top is extruded by customer and sprays product formulation.
Sealing member 52 is the flexible materials the space sealing between mounting cup 50 and valve rod housing 48.Sealing member 52 is preferably made up of rubber or similar flexible material.Sealing member 52 is preferably shaped to packing ring.Sealing member 52, sealing between valve rod housing 48 and mounting cup 50 is formed by carrying out compressing during the crimping of mounting cup 50.Extruding on valve rod 46 can make the sealing of between sealing member 52 and valve rod housing 48 and between sealing member 52 and mounting cup 50 washer-shaped be out of shape a little.
Dip tube 42 is the product formulation that stores in container (not shown) access points to aerosol valves 40.
Compare with the flow path of the aerosol valves of prior art, aerosol valves 40 has less unexpected change in flowing side.This tendency of solids accumulation in flow path decreased in product formulation by the less site providing particle to gather, thus decrease product bug.
Fig. 5 and Fig. 6 shows the embodiment of the valve rod 46 with four (4) paths 64,66,68,70 perpendicular to one another.The cross-sectional plane of path 64,66,68 and 70 is comparatively large, with product by time reduce resistance as far as possible and thus reduce the gathering of the solid in product formulation, reduce hazard rate.
Path easily allows product formulation directly to flow through the space central authorities (know in figs. 3 and 4 and illustrate) inside Compress Spring 44 from dip tube 42, and gradually deflects around valve rod 46.Valve rod 46 is preferably thinning valve-rod body.These structures and configuration decrease product formulation and arrive the flowing back pressure (resistance) before valve rod hole 58.This is the advantage being better than conventional valve flow path, and conventional valve flow path needs unexpected change in the flowing direction, and needs by long and narrow groove before arrival valve rod hole.
Aerosol valves 40 preferably considers that valve rod housing, Compress Spring geometry and valve rod are molded the constraint of performance (for intensity and moldability) and form most probable feasible flowing path cross section.In the exemplary embodiment, express with the ratio % of the complete internal diameter of the cross-sectional plane of flow path (path) and Compress Spring coil, about 49% of the available cross section inside Compress Spring coil is divided into four paths.
Fig. 7 A shows the view of aerosol valves 40, shows the position of Compress Spring 44 relative to path 64,66,68,70.It is (the opening) compressed completely that Compress Spring 44 is depicted as in fig. 7, just as the state of spring when aerosol valves 40 is fully actuated.Fig. 7 B is the view same with Fig. 7 A, but adds top shadow to be clearly shown that these parts.
Fig. 8 A shows another view of aerosol valves 40, to demonstrate the position of Compress Spring 44 relative to path 64,66,68,70.In fig. 8 a, Compress Spring 44 is shown as and compresses completely, just as the state of spring when aerosol valves 40 is fully actuated.Fig. 8 B is the view same with Fig. 8 A, but adds top shadow to be clearly shown that these parts.
Fig. 9 shows the valve 40 under middle of stroke, this be when valve rod is extruded by customer and sprays product valve from its do not activate (closing) position be transitioned into activate (opening) position completely time valve of short duration midway location.When valve is in this midway location, product formulation is boosted through the center of Compress Spring 44 primarily of main flow path 60.But, in the traverse time that this is of short duration, some product formulation around the Compress Spring 44 in minor flow path 62 coil between space 45 move.
Figure 10 and Figure 11 shows the cross-sectional plane that valve 40 is in its complete actuated position.Valve rod 46 makes Compress Spring 44 compress completely, and this reduce or eliminates the space 45 between coil.Thus, illustrate as Figure 11 knows, under total travel, the product formulation of nearly all (or all) moves up in aerosol valves 40, and through the center of Compress Spring 44, this is depicted as main flow path 60.Compare with the flow path in existing aerosol valves (such as, comparing with the main flow path 30 of above-mentioned prior art), main flow path 60 is shorter and so not tortuous.This shorter so not tortuous flow path decreases the possibility of the solids accumulation in product formulation, and reduces product bug.
As shown in Figure 11 (and Fig. 7 A and Fig. 7 B and 8A and Fig. 8 B), the geometry of Compress Spring 44 and comparatively MP major path 64,66,68,70 introduce product formulation, with the almost complete center upwards flowing through Compress Spring 44 along main flow path 60, and be still positioned at the space that limited by spring coil and exit the upper end of Compress Spring 44.
On the contrary, in addition as shown in figure 11, interaction when activated valve 40 between valve rod 46 and Compress Spring 44 allows little product formulation or does not have product formulation to move up via minor flow path 62, and minor flow path 62 is the paths outside Compress Spring 44 and between each coil.Equally, this is because have little room when activating aerosol valves completely or there is no space between each coil.Because less product formulation moves along (assisting) route of these longer complications, the probability of the solids accumulation in flow path reduces, and because of product bug minimizing.
In the exemplary embodiment, product formulation of the present disclosure is the compound of two type media, such as the compound of powder (solid) and propellant.
experiment
Test tests with the product formulation of high solids content the aerosol valves proposed, and consequently in whole life test, does not have recordable product dispensation fault diagnosis example.This tests to be formed with the laboratory utilizing known existing aerosol valves design to carry out and contrasts, and known existing aerosol valves design causes losing efficacy owing to demonstrating the gathering of the high solids content preparation of the difficulty of assembling tendency.
Additionally provide the method using above-mentioned free-pouring aerosol valves to send high solids product preparation.Described method uses such aerosol valves: compare with existing aerosol valves, there is shorter flow path, the change of less direction and path greatly, to minimize the gathering of the solid in flow path and to reduce the product bug such as caused due to the obstruct of flow path.
As used in this application, for size, weight and other wording " about " measured refer to statement value ± scope of 10%, more preferably for institute's statement value ± 5%, and be most preferably statement value ± 1%, comprise all subranges therebetween.
