Abstract
A pressurised dispenser valve (110) has a valve housing (111) with at least one fluid inlet (127, 128) though which a fluid present in an associated dispenser may pass to enter the valve housing. The at least one fluid inlet is formed at least partly by, or in a resiliency deformable portion (124, 125) of the valve housing. The deformable portion (124, 125) is arranged such that, in use when the valve is opened, it deforms from an initial resiliency biased configuration in which the fluid inlet (127, 128) has an initial cross sectional area to a deformed configuration in which the fluid inlet has an altered cross sectional area in response to a pressure differential between the interior of the housing and the exterior of the housing. The change in cross sectional area of the inlet can be made to vary independence on the pressure in the canister and can be used to control the rate of flow of the fluid through the inlet as the pressure in the canister falls during use.
Description
Technical field
The present invention relates to a kind of valve that is used for pressurised dispenser, and a kind of pressurised dispenser with this valve.
Background technology
Knownly provide a kind of pressurised dispenser that comprises the container that wherein under pressure, product is stored or tube jar (canister).Valve is set so that can be from the tube jar when valve is opened allocated product.The product that is assigned with is liquid often, and for example juice, and propellant also is used as pressure gas to small part and is present in the tube jar.Some propellant component such as butane exists as liquid as gas and part, and they are dissolvable in water in the liquid product.Other propellant such as pressurized air or nitrogen only exists as gas, and for such as carbon-dioxide propellant, can keep limited amount this gas in liquid with suspending.Therefore in some pressurised dispensers, liquid product is maintained in the flexible pouch in the tube jar, separates with propellant.
Nozzle usually utilizes valve rod to be assembled on the outlet valve, is transferred with form and the direction that is suitable for using to guarantee product.Many distributing boxs have the atomizer that is assembled on the outlet valve, this nozzle be constructed such that flow of liquid under pressure by this nozzle, so that it is broken or " atomizing " becomes countless drops so that formation atomisation or mist when the egress hole by nozzle.A large amount of commercial products is presented to the customer with this form, comprises for example antiperspirant sprays, deodorant spray, perfume, air freshener, anti fouling composition, coating, insecticide, glazing agent, hair care product, medicine, water and lubricant.In other application such as shaving foam, nozzle is suitable for the form allocated product with foam or gel.
The pressurised dispenser that is configured to produce atomisation usually is called as aerosol dispenser, but this term is applied to all pressurised dispensers sometimes usually, or even wherein with those distributing boxs of for example form of foam rather than atomisation form allocated product.
In aerosol dispenser, the optimal size of required drop depends primarily on relevant specific products and expection application thereof in the spraying.For example, comprise expection and needed very little drop usually by the drug spray of the medicament of patient's (for example, asthma patient) suction, this drop can be penetrated in the lung deeply.On the contrary, polish spray preferably includes has larger-diameter spray droplet, will be to promote that aerosol droplets is impacted by the surface of glazing, and especially,, then can reduce the suction degree if spraying is deletrious.
The size of the aerosol droplets that conventional spray nozzle equipment produces is by the size that comprises outlet and impel fluid to pass through a plurality of factor controls of the pressure of nozzle.But,, particularly under low pressure, then can have problems if wish to produce the spraying that comprises droplet with narrow droplet size distribution.More and more wish to use low pressure to generate spraying, this is because the amount of the propellant that exists in can reducing to spray like this, perhaps use produce lower pressure such as compressed-air actuated interchangeable propellant.If relevant liquid product has high viscosity, then under low pressure provide the problem of high-quality spraying further to worsen, this is because more be difficult to fluid atomizing to be become enough little drop.
Another problem that is equipped with the known pressurized aerosol distributing box of conventional valve and spray nozzle equipment be at aerosol dispenser life period, especially near latter stage in service life of distributing box, because the pressure in the tube jar reduces when the content article become depleted gradually, therefore the size of the aerosol droplets that produces trends towards increasing.This pressure reduces the big or small of aerosol liquid that causes generating and obviously increases, thereby the quality variation of the spraying that produces.
Depend in the amount of the life period pressure decay of distributing box use propellant type and change.When both are present in the tube jar as liquids and gases such as the propellant of butane, can be 20-30% in the decline of the life period pressure of distributing box.For this propellant, when product is used up, produce more gases from solution, and the pressure decay in the tube jar.As a comparison, propellant mainly or only exists as pressure gas, and total pressure decay can be 50% or bigger.
In order to help the breakup of drop and to improve atomizing, some known aerosol dispenser valve is arranged such that when liquid product is assigned with, perhaps in valve itself, perhaps flow of liquid and air-flow keep in valve under the situation of seperating vale separately in the downstream of valve therein, and a spot of propellant gas is introduced into this liquid product.Gas and liquid mixing and expansion when liquid passes through the outlet of nozzle help to make liquid crushing become less drop.In a kind of known equipment, one or more pores or opening are set in valve pocket, propellant gas can be discharged in the liquid product by this pore or opening when liquid product flows through this valve.This is known as gas phase tap (VPT)
A problem using VPT or other to be used for when liquid is assigned with propellant gas being introduced the equipment of liquid is that propellant gas is more promptly more depleted than other situation, has aggravated the problem of the loss of pressure with in the life period tube jar of distributing box discussed above.No matter how this all is a problem to the propellant that uses, be for example air or nitrogen of pressure gas but work as propellant, when loss of pressure may cause unacceptable performance when the content article are depleted, this was a special problem.For example, do not have VPT and using in the typical dispenser of pressurized air as propellant gas, starting pressure will be about 10 crust, be reduced to about 4 crust.But if use VPT or miscellaneous equipment, pressure can be reduced to and be lower than 2 crust, and this pressure often is not enough to atomized liquid.For this reason, the known pressurised dispenser with pressurized air propellant does not have VPT usually.
For the atomized liquid product, preferably, the pressure in the tube jar be lower than when tube jar be full and pressure when higher, the equipment that is used for propellant gas is introduced liquid product produces the higher propellant gas and the ratio of liquid.This is because under higher pressure, and the higher relatively flow rate of the liquid by nozzle usually is enough to separately cause required atomizing, and need not propellant gas is introduced flow of liquid.But, for conventional VPT, can see reverse effect, the ratio of propellant gas and liquid reduces when the pressure decay in the tube jar.This can illustrate by the stream of considering process VPT.Because the pressure in the valve pocket is lower than the pressure of the gas outside valve pocket when valve is opened, gas flows through VPT, and the gas flow rate that flows through VPT is the function of the difference of pressure at the cross-sectional area of VPT and its two ends.Because the cross-sectional plane face of known VPT connects and fixes, therefore the volume flow rate by VPT is because of the pressure decay in the tube jar when valve is opened, thereby the difference of pressure at valve pocket two ends decline and reducing.
For when when the latter stage near life-span of distributing box, the pressure in the tube jar reduced, guarantee that enough gas is discharged in the liquid to realize the suitable atomizing of liquid, conventional VPT opening must have certain minimum size.But, this means when tube jar be full and pressure when higher, excessive propellant gas is discharged in the liquid.Therefore, can see that for the VPT device of routine, the appreciiable propellant gas by the VPT discharging when the tube jar is relatively expired is wasted, this is because they are unnecessary for the suitable atomizing of guaranteeing liquid.Because propelling gas can be compressed, and therefore for given volumetric flow rate, almost be empty with the tube jar and tube jar in pressure compare when having descended, more substantial gas will be by VPT when the tube jar is full and is in its top pressure, the complexity so this problem further becomes.
In order to address the above problem, the applicant has proposed to have the aerosol dispenser of such valve in international patent application communique No.WO2006/095153, this valve comprises the flow control device that is used for when liquid product is assigned with propellant gas being introduced the device of liquid product and is arranged to increase when its length of life reduces when the pressure in the distributing box propellant gas and the ratio of the liquid product that is assigned with.Disclose some embodiment that are used to realize this effect in this application, the content of this application is incorporated into here in full.At one especially in the advantageous embodiments, valve has two flow control mechanism, flow control mechanism is used for pressure change propellant gas according to the tube jar and is discharged into speed in the juice, and another flow control mechanism also is used for the speed that the controlling liquid product stream is crossed valve according to the pressure in the tube jar.Use two flow control mechanism to make when the pressure in the tube jar reduces in this way, can increase the ratio of propellant gas and liquid product in a controlled manner.
Disclosed flow control mechanism comprises the opening that be arranged in wall of fluid by wherein among the WO2006/095153, and the flow-control element that shows as the form of disk, this flow-control element is biased on this wall by the difference of pressure at these opening two ends when valve is opened, to suppress the flowing of fluid by this opening.Disk is stacked on this opening, but is arranged to not form extraordinary sealing with wall, thereby fluid can be by entering this opening between wall and the disk.By the design that is fit to of wall and disk, change flow rate in the time of can being arranged such that pressure decay in the tube jar of leakage between wall and the disk with the control fluid.
Disclosed flow control mechanism is an actv. among the WO2006/095153, but when they when for example glazing agent, hairspray, coating, antiperspirant etc. use with the liquid product of certain type, they may get clogged or adhere.
Therefore, the valve that need have an improved flow control mechanism overcomes or alleviates in the problem relevant with known flow control mechanism some or all at least.
Also find, change the mode deliver gas in the valve pocket by VPT and cause significant different with the liquid size for the Sprayable of aerosol.Especially, have been found that and use several big holes of little VPT boring ratio to realize better effect.Think and use several apertures to promote gas and liquid in valve pocket, to mix.But, have difficulties at the manufacture view of aperture.Typically, valve pocket is by the polymeric material injection moulding, and the use pin forms the VPT hole in mould.In order to produce less hole, the size of pin need reduce, if but use very thin pin, then these pins fracture possibly.Another problem that bring in very little hole is that they can get clogged, the liquid that will be assigned be the lacquer etc. situation under especially true.

The specific embodiment
Under each situation, identical drawing reference numeral (hundred add) is used for illustrating that the following examples have the technical characterictic of identical or identical functions.
Fig. 1 illustrates first embodiment of positive type dispenser valve 10.Valve 10 has the plastics valve pocket 11 of the hollow that is installed on the metal cupule 12, and this metal cupule 12 forms the part such as the upper surface of the pressurised dispenser of aerosol tube jar.As known in the art, the dispenser cartridge jar will typically hold the liquid product and the propellant that will be assigned with, and this liquid product can be juice, gel etc., and at least a portion of this propellant is present in this liquid product top as gas.Propellant makes tube jar supercharging, makes that product is assigned with when valve is opened.Can use any suitable propellant, for example butane, pressurized air, nitrogen or carbon dioxide.But the present invention especially is advantageously used in such distributing box, promptly wherein propellant only or mainly as pressure gas for example pressurized air, nitrogen or carbon dioxide or have the VOC composition of other minimizings.
Seal liner is located in the recess of upper end of this valve pocket, and the outside diameter of this liner is sandwiched between the base portion of cupule 12 and this recess.Valve member 14 is positioned in the valve pocket slidably, and by the spring bias voltage that makes progress.All-in-one-piece valve rod 16 is outwards outstanding from valve member.The bottom of valve pocket 11 forms connection pipe (spigot) 17, and connection pipe 17 provides the inlet that leads to valve.Dip-tube 18 is installed on the connection pipe 17 in a usual manner.Valve rod 16 is a hollow, has from the upper surface of valve rod to extend to obstructed axial flow of fluid path 19 main body of valve member.Lateral fluid path 20 extends from the bottom of axial passageway 19, and leads to the recessed outer circumferential area 21 of valve member.When valve was closed, as shown in Figure 1, liner was bonded in the recessed region 21 to seal the opening of cross walkway 20.Prevent that like this fluid in the valve pocket 11 from entering cross walkway 20 and leaving valve by axial passageway 19.
The actuator/nozzle (not shown) is installed in the upper end or the distal portion of bar 16 usually in mode well known in the art.This actuator/nozzle will generally include atomizer, and this atomizer is arranged such that the fluid breaks that flows through this nozzle when valve is opened becomes liquid or is atomized to form spraying.But in some applications, actuator/nozzle can be configured to the form of foam allocated product.
When dispenser valve 10 did not activated, as shown in Figure 1, valve member 14 was spring-biased to its top or make position, thereby cross walkway 20 is sealed by liner, and the valve closure.For actuated dispenser, exert pressure to actuator/nozzle, make being biased in the valve pocket as shown in the figure downwards or moving inward of valve member 14 antagonistic springs, becoming until the opening of recessed region 21 and cross walkway 20 exposes below liner.Then, the pressure in the tube jar forces liquid product to pass through axial passageway 19 in cross walkway 20 and the bar 16, and the escape passage that enters actuator/nozzle thus is assigned with the one or more outlets by actuator/nozzle.When the downward pressure on being applied to actuator/nozzle was removed, spring upwards was biased into position shown in Figure 1 with closed valve with valve member 14 once more.
Valve pocket 11 has base portion 23, this base portion 23 is formed by the polymeric material of first substantially rigid, and part or zone 24,25 with two elastically deformables, each in 24,25 of the part of this elastically deformable or zone are that the polymeric material of elastomeric flexible forms by comparing with first rigid material at least in part.Preferably, valve pocket uses the double injection technology to be injection molding, in this technology, use the first material molded body part at first injection stage, and in second injection stage, form two deformable regions 24,25, in second injection stage, the elastomeric flexible plastic material is over-molded onto on first rigid material.Two deformable regions 24,25 will be formed by same material usually, but they can be formed by different materials.The part of substantially rigid can for example polypropylene or nylon plastic(s) form by rigid plastic material.The zone of elastically deformable can for example TPE, TPV, flexible polypropylene etc. form by flexible plastic material is arranged relatively.
Statement used herein " rigid plastic material " is in case refer to the rigidity that is molded as desirable shape then has relative higher degree and the plastic material of intensity.
Term used herein " flexible material " is in case refer to and be molded as desirable shape then be the plastic material of flexible/elastically deformable inherently.For example when bottle for preparing shampoo or shower gel container, use this material.
First deformable region 24 forms the part of the sidewall 26 of valve pocket.First deformable region 24 has opening or the hole 27 that forms fluid intake or VPT, and the propellant gas above liquid that exists in the tube jar when valve 10 is opened can enter valve pocket to mix with liquid product by this fluid intake or VPT.Extend the bottom that another deformable region 25 is crossed over connection pipe 17, and also have opening or hole 28, and this opening or hole 28 form another fluid intake, and liquid product enters valve pocket by this fluid intake when valve is opened.
When valve 10 closures, the pressure in the valve pocket will be identical with the still pressure outside this valve pocket in the tube jar.But when valve was opened, the inside of valve was connected with atmosphere via bar path 19,20, thereby the pressure in the valve pocket 11 reduce.This causes having difference of pressure between valve pocket inside and valve pocket outside, and the pressure extent is the function of the pressure in the tube jar.
In particularly preferred embodiment, deformable region 24,25 is arranged such that pressure in tube jar when the length of life of distributing box descends, and gas increases with the ratio of the liquid that is assigned with.One skilled in the art will understand that the multiple mode that realizes this effect that exists.For example, second deformable region 25 can be formed at the flow rate substantially constant of the length of life maintenance of distributing box by the liquid of valve 10, and first deformable region 24 is when being constructed such that pressure decay in the proper tube jar, and the flow rate that enters the gas of valve pocket 11 by opening 27 increases.Selectively, second deformable region 25 can be configured such that the flow rate of the liquid by valve reduces when the pressure decay in the tube jar.Typically, the flow rate of the length of life of the distributing box liquid by opening valve reduce will be up to about 30%.By this selectable layout, maintenance entered the flow rate substantially constant of the propellant gas of valve pocket 11 when first deformable region 24 can be formed at pressure decay, and perhaps its flow rate that can be configured such that gas increases.
Increase the flow rate of the gas that enters valve pocket 11 during for the pressure decay in the tube jar, first deformable region 24 is arranged such that the cross-sectional area of opening 27 non-linearly increases when valve is opened when the pressure decay in the tube jar.This can be by forming opening and/or realizing so that opening non-linearly is out of shape with respect to pressure around the profile of the deformable region of this opening.A kind of mode that realizes this is to make opening 27 form the horizontal or horizontally extending ellipse of its major axis.When the tube jar is in full pressure, opening will be by almost completely closed when valve is opened, but opening will be less closed in vertical direction when pressure decay, make for given pressure drop the cross-sectional area of the opening amount that the situation increase of ratio such as circular hole is bigger when valve is opened.
Although in described embodiment, in the deformable region 24,25 each has single opening 27,28, it should be understood that, in this embodiment or in any of other embodiment that will be described, any in the deformable region or both can have more than one opening 27,28.For example, in some applications, when the pressure decay in the tube jar to for example can be the time at the low pressure in the zone of 0.4-0.5MPa (4-5 crust), this typically be equal to tube jar liquid content about 90% by situation about being used up, wish to have unexpected, may be the increase of the flow rate of the propellant gas that passes through VPT of jump function.This unexpected increase can by in first deformed region 24, have second or another VPT opening realize, when valve is opened this second or another VPT opening is closed or closed substantially, the pressure decay in the tube jar is to can be at the predeterminated level in the scope of 0.4-0.5MPa.In case pressure has dropped to or has been lower than this predetermined value, this another VPT opening is opened at least in part when valve is opened, and making provides additional flow path in valve pocket.It is that air and the ratio that under low pressure needs air and liquid significantly increase under the situation with the quality that keeps spraying and be particularly useful that fluid by VPT this is increased in propellant gas.Should be understood that the shape of the shape of this another opening and the position and first deformable region 24 and structure all can be treated to makes this another VPT opening only open under desirable pressure.Selectively, first deformable segment 24 and opening 27 can be constructed such that, the pressure decay in the tube jar to or be lower than predetermined value, promptly, in the time of once more can be in the scope of 0.4-0.5MPa, the cross-sectional area of VPT opening 27 increases suddenly or as jump function when valve is opened.
According to the character of the material that uses, deformable region 24,25 was compressed in the moment that is under pressure, and pressure is high more, and then compression degree is big more.This may be a problem when being used for pressurised dispenser, is difficult to predict how it will react when pressure reduces because compression material along with the time may be lost elasticity in the past, makes.This problem may be worse in aerosol dispenser, because the chemical of many uses also can react with this material, and distributing box may not use and can be used for different weathers many years.Therefore, preferably, deformable region 24,25 is arranged to by bending or distortion plastic deformation changing the cross-sectional area of opening 27,28, and does not rely on the compression of material.But in many application, but the relative compression of materials used is controlled flow rate with the cross-sectional area that changes opening when pressure decay.For example, can be in the relatively thicker section of material the inlet porting opening, make under high pressure because this material of some of them material deformation is extruded to this opening with closed this opening of part.
Fig. 2 illustrates second embodiment according to valve 110 of the present invention, and wherein, first and second deformable regions 124,125 have aforesaid angled wall or surf zone.Except valve 110 is the seperating vale, wherein gas flows through this valve to mix with liquid along the flow path that separates in the nozzle (not shown), and valve 110 is similar to first embodiment.Therefore, valve 110 has isolated second seal liner 130 below upper liner 113 in the upper end of connection pipe 117 in this valve pocket.Valve member 114 has the axial protrusion 131 of downward extension, and its lower end part is in lower pad 130.Axial passageway 119 in the valve member is extended along this axial protrusion, and is connected with cross walkway 120 near the bottom of protrusion 131.This layout makes that the opening of cross walkway 120 is sealed by lower pad when valve member is positioned at its top, make position, thereby liquid product can not enter cross walkway to leave valve via axial passageway 119.
When valve 110 activated, to the actuator/nozzle (not shown) of the upper end that is installed to bar 116 apply downward pressure so that valve member as shown in the figure downwards or move inward, thereby the lower end area of protrusion 131 moves below lower liner seal so that liquid product can flow through laterally and axial liquid path 120,119 so that be assigned with.Simultaneously, the open lower end portion of gas passage 132 moves below upper liner 113, thereby propellant gas can flow through axial gas path 132 and enter the nozzle (not shown), propellant gas and liquid mixing in nozzle.When propellant/nozzle is removed pressure, spring 115 upwards is biased into position shown in Figure 2 with closed valve with valve member.
Lower pad is divided into two parts with the inside of valve pocket: top part 111a and bottom part 111b, propellant gas can enter this top part 111a via the VPT opening 127 in first deformable region 124, and liquid product can enter bottom part 111b via the opening 128 in second deformable region 125.In the present embodiment, the lower pad 130 and first deformable region 124 are integrally formed into, but this situation is optional.Lower pad has the boring 133 of perforation, and this boring has upper area 133a, and upper area 133a engages the outside face of valve member protrusion 131 to seal with its formation.The lower area of this boring is a conical butt, outside convergent on downward direction.When valve member 114 is depressed with actuated dispenser, the lower end area of protrusion 131 enters the cone part of this boring, thereby liquid can enter horizontal fluid path 120, and liner continues to form sealing around protrusion 131 above cross walkway 120, enters the top part of valve pocket or prevents that propellant gas from entering the bottom part to prevent liquid.
Shown in the modification of layout in, lower pad 130 can be modified to be formed for the spring of valve member 114, can save spring 115 in the case.
As in Fig. 3 best as seen, the lower walls 135 that first deformable region 124 has sidewall 134 and extends with the about 90 degree ground of 134 one-tenth of sidewalls.In this embodiment, VPT opening 127 forms in sidewall.When valve was opened, the difference of pressure that acts on the lower wall 135 upwards applied power to this wall as shown in Figure 2, helped compression or distortion sidewall so that closing any opening 127.In this arranged, lower wall can be formed by rigid material at least in part.Second deformable region 125 has frusto-conical, and it has sidewall surfaces 136 that liquid inlet 128 is positioned at convergent wherein and flat substantially lower end wall 137.When valve was opened, the pressure that acts on the liquid on the outside face of lower end wall applied power upwards, and it trends towards compressing or twisting the sidewall areas of convergent, thereby makes liquid inlet 128 closures.Lower end wall 137 can be rigidity or flexible.
Fig. 4 illustrates the selected embodiment of valve pocket 111, and wherein the opening 127 in first deformable region 124 is arranged in the inferior wall area 135.In this arranged, the pressure that acts on when valve is opened on the sidewall areas 134 helped compression or distortion lower wall 135 with closing any opening 127.Opening 127 is formed the ellipse that has along the main shaft of the horizontal expansion of valve pocket in this embodiment.
Fig. 5 and 6 illustrates the embodiment of slightly modified of second deformable region 125 of valve pocket 111.Fig. 5 illustrates the embodiment that wherein has two opening 128a, 128b by the sidewall areas of convergent.As shown in the figure, opening 128a, 128b can have different sizes.In the embodiment shown in fig. 6, lower end wall 137 caves inward on its outer surface, and time domain is out of shape or the mode of distortion when valve is opened to change.These embodiment show and can adjust deformable region some different modes with required flow characteristic that valve is provided.Should be understood that the multitude of different ways of revising deformable region can be used for realizing desirable effect.
As illustrated in fig. 1 and 2, pressurised dispenser is attempted with roughly vertical orientation operation.On this orientation, liquid product occupies bottom, the bottom of container, and is drawn in the valve by dip-tube.But if distributing box is inverted, then propellant gas will move to the bottom of the tube jar that is positioned at topmost now, and if valve activated, then the very major part of propellant gas will be lost by valve.In order to prevent this loss of propellant gas, some dispenser valves are assembled the layout that is closed to the fluid intake of valve when valve is inverted.Therefore, the valve shown in Fig. 2 110 has the ball-bearing casing 139 that is arranged in connection pipe 117.When valve was inverted, ball 139 sealed near flexible gaskets or sealing member 140, to prevent in distributing box propellant gas loss under inverted situation about activateding simultaneously.During normal running, the power that enters the liquid of connection pipe 117 is enough to make ball-bearing casing to pass through to allow liquid from 142 liftings of its underpart seat, and can not make it to contact with sealing member 140 by the extrusion ball bearing.
Though ball-bearing casing 139,239 is mainly attempted to prevent when distributing box activated the propellant gas loss under inversion state, its also can be used for preventing when distributing box do not use and when being in vertical state the bottom and the dip-tube of connection pipe be full of propellant gas.Under the situation that does not have ball valve 139, propellant gas will trend towards entering valve and dip-tube by VPT, equate with the liquid level of liquid in the remainder of tube jar up to it with the liquid in downward promotion valve and the dip-tube.This causes, and quite a large amount of propellant gas is wasted when valve is opened for the first time.Arrange that by ball valve of the present invention ball is placed on the lower seat 142, the sealing dip-tube prevents that like this gas enters valve when valve is closed.If desired, can provide another sealing at the lower seat place.Another embodiment according to valve 210 of the present invention is shown in Figure 7.Except the seat 240 that is used for ball-bearing casing 239 is formed integrally as the extension of lower pad 230, valve 210 is similar to previous embodiment.Therefore, lower pad 230 is extended downwards to form the sealing member 240 of O type lopps type around the internal bore of connection pipe above ball-bearing casing.If distributing box is inverted when it activated, then ball-bearing casing will form sealing to prevent that propellant gas from losing by valve with O type ring 240.For assembled valve, ball-bearing casing 239 can be inserted into by the lower pad 230 with distortion.
Although above-mentioned inverted ball valve arranges that 139,239 is actv. preventing when distributing box is inverted aspect the propellant gas loss, if valve 10,110,210 is opened when distributing box only partly is inverted, propellant gas loss may be taken place then.If valve is opened when the distributing box inclination makes the free end of dip-tube not be immersed in the liquid, thereby there is not liquid to be inhaled into valve, and propellant gas still centers on the VPT opening simultaneously, then a large amount of propellant gas will be assigned with, and this is will must not resist with flow of liquid because of the air-flow by VPT.In order to overcome this problem, spherical inversion valve can be arranged on the downstream of VPT.In the valve of not separating of all valves as shown in Figure 1, for example, be inverted valve and can be arranged in valve rod 19 or nozzle.In the seperating vale (divided valve) of the valve shown in Fig. 2 and 7, two inversion valves can be set, an inversion valve is in normal gas flow path, and another is in the normal liquid flow path.For example, except by the inversion valve 139,239 of shown in Fig. 2 and 7, locating, another can or be set in nozzle in gas passage 132,232 be inverted valve.Interchangeable, even but distributing box can have the still equipment of dispense liquid that makes when distributing box is inverted.This can comprise disclosed any equipment in applicant's the international application that is published as WO 2004/022451, and this international application is incorporated this into by reference and in full.
As shown in Figure 7, the opening 227 in first deformable region is set in the sidewall 234, but as an alternative, it can be arranged in the lower end wall 235.In fact, any one in the layout described in any embodiment can be used for described any other embodiment.
In the above-described embodiments, first deformable region 24,124,224 is arranged in the sidewall areas of valve pocket.Although this is a position easily, it should be understood that first deformable region can be arranged on any suitable position on the valve pocket.Similarly, second deformable region 25,125,225 must not be positioned at the arrival end of connection pipe, though this is an especially favourable position.
When valve according to the present invention will be used to have form and be the distributing box of propellant of pressure gas such as air or nitrogen, and especially when liquid flow rate low when for example being lower than 0.6g/s, VPT opening 27,127,227 needs very little, has the cross-sectional area in the hole that is equal to the 0.15mm diameter sometimes.It is very difficult producing this little opening, especially true in Quantity production.If utilization is passed material with pin and formed opening, then there is the trend that ruptures owing to its small size of selling.The danger that also exists this little opening in use partially or completely to be blocked.In order to overcome these difficulties, have been found that this opening or be especially favourable for very thin slit in a plurality of opening productions during with upper shed of one of needs.
The method of any suitable formation slit can be used.In one approach, after elastomeric material is by molding soon, will have the slit length that approximates hope greatly length, but have greater than the pin of the thickness of desirable thickness in final slit and inserted this elastomeric material.This can carry out in molding tool, perhaps carries out soon after taking out from molding tool at valve body.When pin is removed, flexible material trend towards being shaped again and closed this opening to stay thin slit.In an example, use length to have the slit of about 0.9mm * 0.05mm or littler size as the pin production of 0.7mm as 0.9mm and the degree of depth.The use pin thicker than actual slot can reduce the tendency of pin fracture or distortion.Another method of producing slit is to expose the zone of the material that will form slit in mould, and makes pressurized air or this material of another kind of gas blow to form slit.Moving pin in mould can be used for the zone of exposed material.In some instances, a part that can be used as moulding process forms slit.
Find that thin slit is easier to make than the circular hole that is equal to, and more difficult in use obstruction.Slit can be shaped as has crooked lateral edges, and it is to work with the similar mode of above-mentioned elliptical openings in the case.Therefore, when valve was opened, flexible material was inwardly advanced, and trended towards closed this opening, but material also can be applied thereon and vertically separates to cross over this slit.By these actions of balance, the change that can pass through the cross-sectional area of opening when the pressure decay in the tube jar realizes bigger control.
When VPT opening 27,127,227 is provided with by the form with slit, have been found that, schematically indicate as the dotted line 127a among Fig. 3, advantageously slit is positioned at elastomeric material the edge the middle part but near the rigid bodies part 23,123,223 of valve pocket.Slit 127a can be close to the location, any edge of elastomeric material, but has been found that when contiguous upper limb is located as shown in Figure 3 especially effective.If the centralized positioning of the wall 134 of the contiguous flexible material of slit, thereby then exist slit under high pressure by the danger that outwards promotes from the inside to make that air-flow is excessive.
Liquid inlet 28,128,228 also can be provided by the form with slit.
The change of flow rate by VPT opening 27,127,227 and the flow rate when the pressure decay in the distributing box is influenced by the shape of deformable region 24,124,224 itself and the shape and the size of this opening all can.In the layout shown in Fig. 1,2,3,4 and 7, the deformable region 24,124,224 that wherein is provided with the VPT opening is shaped as the shape and the profile of the rigid element that meets valve pocket 23,123,223 substantially.But, must be so, and deformable segment can be shaped in any suitable manner so that required control to the flow rate by the VPT opening to be provided.For example, deformable segment can have indenture or have outwards outstanding part or the two combination.Fig. 8 illustrates this principle.Accompanying drawing illustrates the part of the valve pocket base portion 211 ' with deformable region 224 ', and this deformable region 224 ' is shaped as provides the angled impression with a plurality of spines and groove.This is an example that deformable segment is shaped as the mode of the profile of the rigid element 233 ' that does not how meet valve pocket or side.
The material behavior of the shape of deformable region and profile, deformable segment and the shape of opening, size and location can all influence the flow rate of passing through VPT opening 27,127,227 when valve is opened and the change of the flow rate when the pressure decay in the distributing box.Therefore, the designer can handle all these parameters to realize the control of desirable flow rate.So same for deformable region 25,125,225 and liquid inlet 28,128,228.
Although advantageously deformable region is formed integrally as the part of valve pocket, but can realize identical effect by using following sleeve pipe or adapter, promptly this sleeve pipe or adapter are assembled on the rigid bodies part of valve pocket, and have with rigid element in the deformable region of suitable register.Sleeve pipe on the connection pipe 317 that is installed to valve pocket base portion 311 or Fig. 9 of adapter 350 are shown show an example.
In the embodiment shown in fig. 9, valve pocket base portion 311 integral body are formed by rigid plastic material, and sleeve pipe 350 is formed by the elastomeric flexible plastic material at least in part.Sleeve pipe has circumferential body subregion 351, its closely slidable fit to the connection pipe 317 of valve pocket 311.Sleeve pipe also has from base portion zone 351 outstanding vertically less diameter extension 352 downwards, and its formation dip-tube will be assembled to the connection pipe on it.The boring 353 of hollow extends through this connection pipe vertically, and is connected with the internal flow in base portion zone 351.The bottom 325 of cover pipe connected pipe 352 is a conical butt, and forms opening 328 the boring 353 of leading to sleeve pipe to be provided and therefore the in-to-in that leads to valve pocket 311 fluid intake is provided by the sidewall of this conical region.But overlap tapered end 325 elasticity and the plastic deformation of pipe connected pipe, and act on second deformable region 25,125,225 of above-mentioned previous embodiment in a similar fashion, to pass through the flow rate of the liquid of valve according to the pressure change in the tube jar.
Near the sidewall areas formation opening 327 of top by the base portion zone 351 of sleeve pipe.Opening 327 leads to groove 356, and this groove 356 extends downwardly into position below the bottom of valve pocket connection pipe 317 along the inside face of sleeve pipe.Opening 327 and groove 356 forms fluid intake or VPT, the propellant gas when valve is opened in the upper area of tube jar can flow through this fluid intake or VPT with the liquid mixing that enters valve pocket 311.Near at least a portion of the sidewall in the base portion zone 351 opening 327 and groove 356 is an elastomeric flexible, and is arranged to when valve is opened distortion or distortion with according to the air-flow of the pressure confinement in the tube jar by this opening and/or groove.For example, sidewall can be at least one point to internal strain, thereby the cross-sectional area that gas flows through groove wherein when valve is opened reduces as the function of the pressure in the tube jar.Sleeve pipe can be formed by the injection moulding of elastomeric flexible polymeric material fully, perhaps can form two mouldings, wherein use the first of rigid polymer material molding sleeve pipe, and flexible portion is over-molded onto on the rigid element in the second molding stage at F/s.
When propellant gas in valve and liquid mixing, as the situation of the unsegregated valve of the valve shown in Fig. 1 and 9, gas forms bubble in liquid.In general, the bubble of formation is meticulous more and even more, and then the quality of the spraying that produces at the nozzle place is just good more.But, if in valve or nozzle, there is too much dead band, the inflatable and combination of bubble, the rate that causes like this producing spraying at the nozzle place is moved.Therefore, valve and nozzle should be designed to the dead band is decreased to minimum.Valve rod 19 becomes problem especially aspect the dead band.In order to reduce the dead band in the valve rod, pipe or bar can insert this boring.This can be the object that independent insertion is holed, and perhaps it can be set to the protrusion on the downside that is positioned at the nozzle on the upper end of bar.For example, little mast can be projected into from the downside of nozzle the valve rod 19 to reduce the dead band.Mast can be shaped as guarantees that gas and liquid keep mixing.In one arrangement, in the outside face of mast perpendicular grooves is set, gas/liquid mixture flows between the wall of this mast and valve rod along this groove.This layout can be used to provide filter, prevents big so that can not enter and stopped nozzles along the particle of groove by valve.Being used for forming this layout of filter in the combination of valve and nozzle can be protected independently mutually with the notion of setting forth in claims of the present invention.
As a kind of mode that reduces the dead band, filter or screen cloth can be introduced valve rod and/or introduced valve itself.Interchangeable layout will utilize the wherein dead band of filling such as valve pockets such as bead or valve rod will become any zone of problem.The size of bead will form big must be enough to not can butterfly gate or prevent that valve member from moving, and will bubble during by this bead the form with thermopnore keep bubble less.This notion can be protected independently mutually with the main inventive concept of protection in claims 1.Pressurised dispenser under high pressure and very rapidly is filled by valve usually.In order to ensure not explosion of deformable region or distortion, perhaps adapter sleeves can not blown off or displacement during filling process, and the dispensers according to the invention valve can have reducing valve, and this reducing valve will be opened so that pressure fluid enters the tube jar.Can use any suitable valve.In a kind of especially favourable layout, little slit is set in one of deformable region or in adapter sleeves.Between normal used life, the pressure in the tube jar will be enough to keep slit closed always.During filling, the liquid in valve pocket or the adapter and/or the pressure of gas will be enough to open slit, can not destroy deformable region or make the deformable region displacement so that make liquid and/or gas can enter the tube jar.
In the above-described embodiments, deformable region is arranged to according to the pressure change gas in the tube jar and the flow rate of liquid, and preferably is arranged to increase along with the pressure decay in the tube jar ratio of propellant gas and liquid.Although this is especially favourable, the present invention also can be applicable to wherein the dispenser valve of a kind of flow rate in control gaseous only or the liquid.Therefore, valve can only have the single deformable region that is similar to above-mentioned first area, to adjust the air-flow by VPT.Replacedly, valve can only have the single deformable region that is similar to above-mentioned second area, to adjust the flow of liquid by valve.
The present invention also can be used for for the pressurised dispenser valve provide fluid intake needn't fibrous root according to the flow rate of pressure change fluid.For example, having discussed above that the very little VPT opening of use is favourable in the valve pocket of valve, because their help gas and liquid mixing, is difficult and produce this little opening in rigidity plastics.These problems can be by providing the VPT opening to overcome in deformable region to be similar to previously described mode.Because opening closure when valve is opened, so these openings can have initial size greater than actual required size by production, and deformable region is constructed such that opening approached required size when proper valve was opened.In this arranges, the cross-sectional area of the opening when valve is opened can keep equating and with the tube jar in pressure independent.
The present invention also can be applicable to provide to valve pocket the fluid intake of automated washing.Because therefore the size and the alteration of form of the opening in the deformable region when the valve open and close can trend towards being evicted from by captive any material in opening.Under any circumstance, will trend towards when valve closure and opening return their bigger initial size, coming off when valve is opened and opening hour blocks opening material.Even material spontaneously moves really, the powerful vibration of tube jar also is enough to evict from any such material.
When the material that for example distributes such as gel, often gel must be contained in the sack that is welded on the valve pocket.In this arranged, propellant gas was maintained in the tube jar of this sack.This is called as bag-on-valve in the art.The dispensers according to the invention valve is suitable for using in the bag-on-valve distributing box.In this arranges, first deformable region will be positioned in the outside of bag, thereby propellant gas can enter valve pocket, and second deformable region can be positioned at bag.
Pressurised dispenser valve according to the present invention can be designed to assemble and be assembled to such distributing box, and promptly this distributing box uses the used existing machinery of conventional pressurised dispenser valve, and this is especially favourable.Similarly, the distributing box that is equipped with according to valve of the present invention can use existing filling machine to fill.As a result, can only adopt less relatively investment cost according to valve of the present invention.
The present invention also has the liquid of the wide region of different viscosities applicable to distribution, this liquid includes but not limited to antiperspirant spraying, deodorant spray, perfume, air freshener, anti fouling composition, coating, insecticide, glazing agent, hair care product, medicine, water and lubricant, foam and gel.
Although described the present invention with preferred embodiment, it should be understood that the present invention is not limited to disclosed layout, and intention comprises various modification and the equivalent constructions that comprises in the spirit and scope of the present invention with respect to being considered to the most practical at present.For example, although described the present invention with respect to its king-rod and valve member all-in-one-piece sun type dispenser valve, the present invention can be applied to its king-rod and the cloudy type dispenser valve of actuator/nozzle all-in-one-piece with being equal to.In addition, in a preferred embodiment, valve is constructed such that flexible portion distortion when proper valve is opened, and closes at the inlet opening that wherein forms with difference of pressure closure or part owing to the valve pocket two ends.But this arranges opposite, thus in the opening any or each can be closed or only very little under initial condition, and the distortion owing to flexible portion enlarges when valve activated.When having two flexible regions, a flexible region can be arranged such that the size of inlet opening reduces when valve activated, and another flexible region is arranged such that the size of opening increases.
