Description

Dispenser nozzle or the improvement relevant with it

Technical field

The present invention relates to the improvement of dispenser nozzle, the method that particularly relates to the improvement of pump-action dispenser nozzle and make this device, but be not limited to this.

Background technology

The pump-action dispenser nozzle device is normally used for offering a kind of device that fluid never can be distributed in the pressurizing vessel.

The problem of traditional pumping action nozzle is that their design is extremely complicated, generally includes many building blocks (comprising 8 to 10 separate parts usually in dispenser nozzle device).Therefore, owing to need wide variety of materials to form these separate parts and with its assembling, these device manufacturing costs are relatively more expensive.In addition, many traditional device volumes huge (this has also increased the cost of raw material), the internal tank that the part of this volume always places this device and connected.Because this nozzle can occupy the part of internal tank capacity, so this is again a defective, this defective especially becomes problem under the small containers situation, and wherein the useful space of this small containers inside is limited.At last, the size of pumping action device is also determined by the size of the container that this device connected to a certain degree.Therefore, the big young pathbreaker of device is restricted in small containers, particularly is restricted more in the narrow small containers of those necks, this has just limited the pressure size that this device can produce, and the amount of the fluid that can distribute, for this reason, this is disadvantageous for device performance.

Summary of the invention

The invention provides the solution that solves traditional dispensers nozzle implications, in aspect first, the invention provides a kind of pump-action dispenser nozzle, this nozzle is adapted such that the fluid that is stored in the fluid source in use distributes through described nozzle, described nozzle has main body, one first chamber of this main part limitation and one second chamber, first chamber has entrance and exit, wherein fluid can be inhaled into described chamber through this inlet, and the fluid in the chamber can be discharged from nozzle through outlet, described inlet comprises inlet valve, only when cavity indoor pressure is lower than at least one minimum threshold of fluid source internal pressure, this inlet valve allows fluid to flow into this chamber, and described outlet comprises outlet valve, and only when internal pressure surpassed at least one minimum threshold of exit external pressure, this outlet valve allowed fluid to flow out chamber and discharges from nozzle, second chamber comprises outlet and outlet valve at least, and one or more section construction that wherein limits the main body of described first and second chambers becomes:

(i) in response to applied pressure, be expansion or deformation state from initial elasticity bias voltage form strain, thereby, because described one or more part of this main body is described expansion or deformation state from described original state deformation, the capacity of the described chamber that is limited by described one or more part of this main body reduces, the increase that reduces to have caused chamber interior pressure of described capacity, thus fluid sprays through outlet valve; And

(ii) when institute's applied pressure is removed, return to initial elasticity bias voltage form subsequently, thereby make chamber capacity increase, internal pressure descends, thereby other fluid is drawn at least the first chamber through inlet valve.

Dispenser nozzle project organization of the present invention is extremely simple, generally include the separate part that is no more than 6 assembles and forms this dispenser nozzle, sprays the problems referred to above that dispenser nozzles exist thereby dispenser nozzle of the present invention has solved many conventional pump effects.In a preferred embodiment, this device will comprise and be no more than 3 parts, perhaps more preferably be no more than 2 separate parts, and perhaps preferred again, this device is made by independent integrally formed parts.For " independent parts ", we are defined as each parts with it and are connected never in any form, just, these parts are not a manufacturing (but each separate part can comprise parts or part that one or more is integrally formed) integrally with other parts.The key that reduces number of components is, essential feature is integrally formed in apparatus main body.For example, chamber, inlet, inlet valve, outlet, outlet valve can be limited by main body, thereby have reduced to comprise separate part and then brought parts and the needs of assembly fee increase.

Further, spray nozzle device of the present invention also provides a kind of two kinds of devices that fluid distributes from spray nozzle device simultaneously that can make.In some special-purposes, this spray nozzle device also comprises third and fourth further chambers.Each chamber can comprise a kind of fluid, and perhaps one or more further chambers can comprise air or another kind of gaseous fluid.

Second chamber can also comprise an inlet, can be from the fluid of second fluid source through this inlet inflow, and wherein second fluid source for example is an independent compartment of the container that device connected.In this case, second chamber preferably includes the inlet that has inlet valve.

In addition, second chamber also can not comprise inlet.The substitute is, the holder of second fluid can be stored in second chamber, and it can distribute single actuating down, and perhaps more preferably, the outlet of second chamber can be configured to actuate second fluid that only allows scheduled volume at every turn and distribute.

As a kind of further optional mode, be included in additive fluid in second chamber and can be gas or such as the multiple gases mixture of air.At latter event, need to spray simultaneously air under some certain applications, this be because, under the situation of spray dispenser nozzle, the mixing of air stream and one other fluid can be divided the spray that distributes and dripped from install, perhaps, and under viscosity fluid ratio such as hair jelly, face cream, shaving foam or the like situation more, for example by producing foam, the mixing of air stream and one other fluid can change the character of spraying product.

At embodiment with the further chambers that is used for discharging air, be to be understood that, discharge air and remove institute's applied pressure in case finish, thereby make the elastically deformable of chamber partly return to initial elasticity bias voltage form, at this moment, more air needs in the intake chamber to replenish the gas of discharging.This can realize (promptly by making outlet valve become two-way valve) by air is sucked back through outlet, and is perhaps preferred, and this can be by sucking through an independent air intake air from external environment condition.Under latter event, air intake preferably has a check valve that is similar to above-mentioned inlet valve.This valve only allows air to be drawn in the chamber, and air is discharged through the hole can prevent the chamber pressurized time.

As a rule, with under the basic identical pressure of air of first chamber discharge, need discharge second fluid simultaneously from second chamber.If second fluid is an air, then need make air chamber be subjected to more compressing (for example, according to related application scenario, many 3 to 200 times) usually than the chamber that comprises fluid/liquid.This can realize by locating this chamber, thereby when exerting pressure, the chamber that comprises air preferentially compresses, thereby makes air can discharge with identical or essentially identical pressure with liquid.For example, the chamber that comprises air can be positioned at the chamber back that comprises liquid, thereby when exerting pressure, air chamber is by first compression, and after arriving certain phase, two chambers compress together again.In addition, air chamber can be positioned at the chamber top that comprises liquid, thereby pressure is applied directly in the air chamber, and pressure is transferred to the chamber that comprises liquid from this chamber more then.Therefore, air chamber will preferentially be compressed.

In addition, dispenser nozzle can also be suitable for like this, promptly makes fluid high or low from the pressure ratio fluid pressure that second chamber distributes, and this is useful in some specific occasion.

When two or more separate parts were arranged in the dispenser nozzle, making the outlet valve of each chamber all open simultaneously was a problem.In view of this reason, preferably structure is constructed to be permeable to pressure is applied to the elastically deformable part of main body, so that outlet valve can twist/open at predetermined point or time.

In optional embodiment, may reside in the single chamber from the air and the fluid of container, rather than in the chamber that separates.In these cases, fluid and air are discharged simultaneously, and are mixing when outlet is flowed out.For example, when outlet comprises an expansion chamber, a chamber of widening is set in exit passageway just, the contents of discharging from chamber can be separated in each branch of passage, and pass through expansion chamber at diverse location, to promote mixing.

No matter it still is some other fluids that additional one or more chamber comprises air, wherein these air or fluid suck from the compartment in the container, and by compressing two or more chambers simultaneously, the contents in these chambers can be discharged simultaneously through outlet.The contents of each chamber will mix in outlet then, this can occur in its when dispenser nozzle is discharged, discharge before or after the discharge.Should be appreciated that by change and separate the relative capacity of chamber and/or the relative scale that outlet size can influence each component in the final mixture that outlet is discharged.And then, exit passageway can be divided into two or more autonomous channels, each passage extends since a separate chamber, and each autonomous channel can inject fluid in the nozzle passage as mentioned above, and this nozzle passage is the passage that the autonomous channel was compiled before discharging.

Chamber can be arranged side by side, and perhaps a chamber is stacked in another chamber roof.In a preferred embodiment, wherein one of further chambers comprises air, and this additive air chamber partly is out of shape and compresses the chamber of dispenser nozzle with respect to the chamber location of dispenser nozzle so that the compression of air chamber causes the elastically deformable of main body.

In some embodiments of the invention, fluid can be discharged from a chamber before or after the fluid of discharging from another chamber.

The chamber of dispenser nozzle can be any form, certainly can understand, and can select the size of chamber and shape to come adaptive specific device and related application occasion.Similarly, all fluids when a plurality of chambers are compressed in a plurality of chambers can be discharged, and perhaps, only are that a part of fluid in these chambers is assigned with out, and this also depends on related application scenario.

In some certain preferred embodiment of the present invention, chamber can be limited by the roughly dome-shaped zone of main body, and this zone can strain.Preferably, this dome shaped region is formed on the upper surface of main body, thereby the operator can cause these regional strains by exerting pressure.

A problem of this cheese chamber is, when the operator compresses it, has some dead band in chamber, and for some application scenarios, this dead band preferably is minimized or in fact can ignores.In order to realize this characteristic, have been found that the chamber of flat-top or other shape is normally preferred.Like this, the elastically deformable of chamber part can be depressed, thereby it touches the relative wall that limits chamber, just preferably can discharge all contents that wherein hold.In view of this reason, flat-top is particularly preferred, and this is because it has reduced for compression chamber and has impelled storage fluid wherein to distribute the degree that need inwardly exert pressure in the top.It is ready to the required amount of exerting pressure of chamber when also having reduced to use for the first time.

In some cases, the elastically deformable part that limits the main body of described chamber may insufficient resilience keep its initial elasticity bias voltage form after deformation.Can to be fluid have that thereby high viscosity is tending towards hindering its situation through the inlet intake chamber for this.In these cases, by one or more strain post is set, can provide extra elasticity in chamber.This strain post bending when chamber compresses, and when institute's plus-pressure is removed, impel the deformable segment of main body to return to its initial elasticity bias voltage form.In addition, one or more thickening ribs of plastic can be extended to the center of this part from edge, strain zone.These ribs pass through to be used as effectively leaf spring, thereby have increased the elasticity in strain zone, and it compresses when pressure is applied to the elastically deformable part of main body, and impels this part to return to initial elasticity bias voltage form when institute's plus-pressure is removed.

Another possibility is that the elastic device of spring or other form is set in chamber.As mentioned above, this spring compression when wall deformation, this spring impels the deformable segment of main body to return to its initial elasticity bias voltage form when pressure is removed, thereby impels compression chamber to return to its initial " not confined state ".

In certain embodiments of the present invention, the elastically deformable of main body part can directly be pushed by the operator.In some cases, this is a problem, because the operator need utilize finger to come the elastically deformable part of compress body.This needs the operator aspect that certain harmony is arranged, and needs the pressure of appropriate amount, and this makes this device not too suitable for some people.And then, use the other parts of health except that finger, such as palm, wrist or ancon, be difficult to touch these devices.

In view of this reason, preferably, some embodiment of the present invention is suitable for providing a rigid actuator surface, thereby the operator can push and can utilize any suitable part of health more easily.

In these cases, preferably, the first that limits the main body of described chamber forms the actuator surface of a rigidity or substantially rigid, wherein pressure can be applied to this surface, and the second portion that limits the main body of described chamber is configured to respond the pressure that is applied to described actuator surface from initial elasticity bias voltage form strain.Thereby described actuator surface is a stretch position from the deformation of initial elasticity offset position, and wherein said chamber has heap(ed) capacity at the initial elasticity offset position, and reduces at the stretch position capacity.The reducing of capacity causes the pressure in the chamber to increase, and fluid is discharged through outlet valve.When applied pressure is removed, the second portion of main body will return to its initial elasticity bias voltage form then, and make the actuator surface recovery to its initial elasticity offset position, thereby cause chamber capacity to increase, pressure wherein reduces, and fluid is injected into first chamber at least through inlet valve.

For " substantially rigid ", we are defined as it, the actuator surface has the rigidity higher than the second portion of main body, and its rigidity is enough to make the second portion generation deformation of main body when pressure is applied to the actuator surface, and the deformation minimum on actuator surface.

Preferably, the actuator surface is positioned at the upper surface of device.Most preferably, this surface entire upper surface of cladding system basically.

Preferably, the area on actuator surface is enough big, so that the operator can utilize palm, ancon and/or wrist to apply pressure on it.

Preferably, the actuator surface is flat or is flat substantially, though it can also be crooked in certain embodiments.Also preferably, the actuator surface keeps its state when pressure applies, yet it also can be configured to the bending of limited extent ground.

Also preferably, the second portion that limits the main body of chamber is the sidewall of chamber or the part of bottom, can carry out strain when wherein the second portion of this main body is pressed on the actuator surface.

The actuator surface can be configured to when exerting pressure its slip or rotate with compression chamber.

In some embodiments of the invention, the outlet of dispenser nozzle goes for producing the spraying of fluid, and wherein this fluid is discharged from one or more chamber of dispenser nozzle.By proper method well known in the art, the outlet of dispenser nozzle can be suitable for carrying out this function.For example, the outlet opening of outlet can be a pore, so that the fluid through its outflow is divided into many droplets under the pressure.Yet in these embodiments, preferably, outlet comprises outlet opening and is connected the exit passageway of chamber to outlet opening.Outlet valve is preferably disposed in the exit passageway.Particularly preferably be, exit passageway comprises that one or more inner sprinkling regulates parts, and these parts can be used for reducing the size of the fluid drop of discharging through the outlet opening of dispenser nozzle during use.Inside in the exit passageway is sprayed the adjusting parts and is for example comprised one or more expansion chamber, one or more eddy chamber, one or more inner spray hole (being used to produce the fluid spray that flows in exit passageway) and one or more venturi chamber (venturi chamber).Comprise the known size that will influence the spray droplets that device produces between the operating period of one or more above-mentioned parts.What be sure of is, adopts separately or in conjunction with the atomizing of the droplet that utilizes these parts to help to produce.These effects of spraying the spray characteristics of regulating parts and influence generation thereof are well known in the art, and are for example described in International Patent Application WO 01/89958, and the whole contents of this application in this combination as a reference.Should be appreciated that enough power is provided when providing the outlet valve that is positioned at the exit passageway upstream and outlet opening to guarantee fluid by exit passageway to be resolved into liquid droplet and form spraying.

In certain embodiments of the present invention, exit passageway and outlet opening can form independently unit or plug-in unit, and its outlet that can be connected to chamber is to form the outlet of dispenser nozzle.This unit or plug-in unit can also be hinged to apparatus main body, thereby make it can screw in desired location when needs use, and screw out this position when not required.

In optional embodiment of the present invention, the liquid in the chamber can be distributed into liquid stream, and it is not separated into droplet.The liquid that distributes with this form for example comprises soap, shampoo, face cream or the like.

Chamber by main part limitation can be limited between two or more interconnecting parts of main body.Particularly preferably be, the chamber of dispenser nozzle is limited between two interconnecting parts, two interconnecting parts are the parts of the independent formation of the qualification chamber that can be installed together, and perhaps more preferably, these two parts can be integrated into a separate part mutually.Under latter event, preferably, these two parts link together by the hinged or foldable connection parts, make that these two parts are molded together in same mould, and they are contacted with each other to limit chamber.

In a preferred embodiment of the invention, its middle outlet comprises outlet valve, outlet opening and connects the exit passageway of chamber to outlet opening that also preferably, at least two interconnecting parts that limit chamber also define at least a portion of exit passageway.Most preferably, these two interconnecting parts form outlet valve betwixt, also define whole exit passageway and outlet opening.

Exit passageway preferably defines between the relative abutment surface of an abutment surface of one of described part and another described part.One or more abutment surface preferably includes one or more and forms groove and/or depression on it, and these grooves and/or depression limited exit passageway when abutment surface contacted.Most preferably, each described abutment surface comprises groove and/or the depression that forms on it, and these grooves and/or depression alignment were to limit exit passageway when abutment surface contacted.Groove and/or depression preferably extend to the opposite edges of abutment surface from chamber, when abutment surface contacted, outlet opening was limited to the end of exit passageway in these opposite edges.In a preferred embodiment, wherein in exit passageway, have one or more and spray the adjusting parts, can form these parts by alignment recess or other structure that is formed on the abutment surface, described in International Patent Application WO 01/89958.

Two parts of this of main body can be permanently fixed together by for example ultra-sonic welded or thermal weld.If bottom and top are molded or weld together, then they preferably are made of compatible material.

In addition, these two parts can be by the tight/resistant installation mutually outside the welding manner, so that nozzle (for example, by providing buckle (snap-fit) to connect) to be provided.For example, the edge of a part may be fitted in the holddown groove of another part, to form dispenser nozzle.

As a possibility, can annotate the compatible plastic material at the junction of two parts mould, so that they are fixed together.This can be achieved like this, and molded these two parts simultaneously in a mould bond them together in this mould to form dispenser nozzle, and mould is annotated appropriate plastic material with these two partial fixings together around them then.

In certain embodiments, these two parts can keep releasable connection each other, thereby they can separate between the operating period, thereby can clean chamber and/or outlet.

Most preferably, these two parts of the dispenser nozzle main body of qualification chamber are bottom and top.Preferably for example screw thread or buckle connect and are installed in the opening of container by appropriate device in the bottom.And then in a preferred embodiment, except forming a main body part that limits chamber, the bottom also preferably defines inlet, and the part of the exit passageway from the chamber to the outlet opening.

Top is suitable for being installed to the bottom, thereby limits chamber between them, and in a preferred embodiment, limits outlet valve, exit passageway and/or outlet opening.In some preferred embodiment of the present invention, bottom and top also define outlet opening.Also preferably, the elastically deformable part of the main body that limits chamber is formed at top.

Preferably, top comprises the first of main body, and the bottom comprises the second portion of the main body of above-mentioned qualification.

The main body of spray nozzle device can be made by suitable material.

In certain embodiments of the present invention, wherein main body comprises two interconnecting parts, and these two interconnecting parts are installed together the qualification chamber, and these two parts are made from the same material or a different material.For example, a part is made by flexible/deformable material, and such as strain plastics or elastomeric material, and above-mentioned another part can be made by rigid material, such as rigidity plastics.These embodiment are preferred for some application scenarios, because flexible/deformable material forms the main body second portion that limits chamber, and can impel the chamber inner fluid to discharge and distortion easily by operator presses actuator surface.This flexible material can also provide a kind of sense of touch of softness for the operator.These embodiment can be joined together to form them the spray nozzle device of assembling then by independent molded two parts, also can adopt bimodulus to annotate technology in same mould and come molded these two parts.At latter event, these two parts can be simultaneously molded, is combined together in mould then, and perhaps, a part is earlier molded by first material, and the second portion that is made of second material directly is molded on the first then.

In addition, these two parts can be made by rigidity or flexible material.Rigidity and flexible material can be that dispenser nozzle can be by its any suitable material of making.For example, it can be made by metal material, such as aluminium foil, also can be made by flexible material, such as rubber.Yet preferably, device main body is whole to be made by rigid plastic material, although can utilize the flexiplast material to form the first of main body when needing.

Preferably, the first of main body is made by rigid plastic material.Most preferably, whole pump-action dispenser nozzle (just, main body and actuator) is made by independent a kind of rigid plastic material.

The wording that is adopted " rigid plastic material " refers to such plastic material here, that is, it just has high rigidity and intensity in case be molded as required shape, but by reducing the thickness of these plastics, some parts it also can more flexible or strain.Therefore, can provide the plastic section of attenuate to assign to form the main body at least a portion that limits chamber and strain.

The term that is adopted " flexiplast " refers to such plastic material here, that is, this nature is flexible/elastically deformable, thereby makes that at least a portion of main body can strain, to help the compression of chamber.It is fixed that the degree of flexibility of plastics can be come according to the plastics thickness on any given area or the zone.This " flexiplast " material for example can be used in the middle of the preparation of shampoo bottle or shower cream container.In the middle of the manufacturing of dispenser nozzle of the present invention, the part of main body can be assigned to form by thicker plastic section, and to provide structure required rigidity, other parts then can be assigned to form by thin plastic section, but so that required deformation behavior to be provided.What if desired, be known as supporting rib usually can appear at some zone that needs additional stiffness than the thickness portion framework.

Forming whole dispenser nozzle by homogenous material makes apparatus main body be molded in the mould and in a molded operation to make, will further discuss below.

Form dispenser nozzle by homogenous material and avoided needs that a plurality of separate parts are assembled, particularly in certain embodiments, two parts are integrally formed, be connected with each other by collapsible Connection Element or hinge connector, thereby top can rotate and touches the bottom to form the dispenser nozzle of assembling.And then, form dispenser nozzle by homogenous material the possibility (for example, by thermal weld or ultra-sonic welded) that two parts are welded together is provided, perhaps,, then can between top and bottom, form buckle and connect if plastic material is a rigid plastic material.A kind of possibility in back can also make top and bottom can regularly separate with cleaning.

For most of application scenarios, dispenser nozzle need be made by rigid material, the required intensity in actuator surface to be provided and to make that two parts can buckle or weld together.In some cases, but the deformable segment of main body only just is tending towards deformation when certain minimum threshold pressure is applied in, and this makes pumping action more be similar to the ON/OFF effect of traditional pump-action dispenser nozzle.Yet in some application scenario, flexible material is preferred.

Main body second portion that can strain can be the part of the rigid plastic material of relative thin, and its strain returns to initial elasticity bias voltage form subsequently with compression chamber when applied pressure is removed when exerting pressure.

Yet in most of the cases, preferably, the abutment surface that limits the exit passageway of outlet is made by rigid plastic material.Though flexible/deformable material also can be used for this purpose, they are not too desirable usually, and parts all need accurately be formed by rigid material usually because all spray adjusting.Therefore, in some embodiments of the invention, one of two parts that limit outlet and chamber can be formed by two kinds of materials, just form the rigid material of the abutment surface that limits exit passageway and outlet opening and the deformable material that limits chamber.

In order to obtain optimum performance, need the outlet of first chamber to have at least or as check valve.Preferably, two chambers comprise a unidirectional outlet valve, but the outlet valve of second chamber can be two-way valve (for example, if second chamber is an air chamber, can allow air to enter second chamber) as mentioned above in some instances.

Providing of check valve is feasible, when only in chamber, realizing predetermined minimum threshold (main body elastically deformable part begins due to deformation causes that the internal chamber capacity reduces from initial elasticity bias voltage form), the fluid that is stored in each chamber can be discharged through outlet, and all closes outlet At All Other Times.Valve cut out when cavity indoor pressure was lower than predetermined minimum threshold, this will prevent the pressure that is applied to main body elastically deformable part discharge and chamber capacity when increasing air be drawn back in the chamber through outlet, wherein chamber capacity increases because of the strain wall returns to initial elasticity bias voltage form.

Also can adopt any suitable check valve assembly that can form gas-tight seal.Yet preferably, the parts by the dispenser nozzle main body form valve.Most preferably, valve is formed between the abutment surface that limits exit passageway.

In some embodiments of the invention, one of abutment surface by limiting exit passageway forms outlet valve, and this abutment surface elasticity is supported relative abutment surface partially to close a part of length of exit passageway.From this point, thereby only be enough to impel this elastic biasing abutment surface deformation to break away from this relative abutment surface when forming a passage of opening at each cavity indoor pressure, this valve is opened to allow fluid to flow out from chamber, wherein from the fluid of each chamber this passage of opening of can flowing through.In case pressure drops to below the predetermined minimum threshold, this elastic biasing surface will return to fexible bias pressure form and closing passage.

In certain embodiments of the present invention, particularly preferably be, the elastically deformable part of elastic biasing abutment surface and main body is integrally formed, limits chamber like this.

In the whole embodiment that is made by rigid plastic material of main body, the resistance that elastic biasing surface (can be the rigidity plastics part that approaches) provides does not have the required minimum pressure threshold of optimum performance that enough elasticity is come implement device.In these cases, can form and cross the plastics thickening rib that passage extends, so that intensity and resistance required in exit passageway/valve to be provided.In addition, can above exit passageway/valve portion, provide the rigidity ribs.

In optional preferred embodiment, by being formed on the elastically deformable parts on one of described abutment surface, can form one or more outlet valve, these elastically deformable parts cross exit passageway and extend to close and to seal this passage.These parts are installed to this device along one of its edge, another edge (preferably opposed edges) is free end, deformation when this free end surpasses predetermined minimum threshold at cavity indoor pressure.This free end is in abutting connection with a surface of exit passageway, to form sealing when pressure is lower than predetermined minimum threshold.Yet when pressure surpassed predetermined minimum threshold, the free end of these parts began deformation from the abutment surface of passage, and to form an opening, the fluid indoor through this atrium can flow to outlet.Preferably, these elastically deformable parts are formed on along in the chamber of the length of exit passageway.Most preferred, abutment surface is tapered with the free-ended contact point of parts place or tilt, and wherein abutment surface forms with the free end of parts when being lower than minimum threshold and seals.This just provides the dot encapsulation contact, and very effective sealing is provided.What certainly can understand is, the free end of elastically deformable parts contacted this inclined-plane when the gradient of abutment surface or tapering must be arranged to make cavity indoor pressure be lower than predetermined minimum threshold, and it will expand this inclined-plane of disengaging when surpassing predetermined minimum threshold.

In addition, valve can be mast or connector, and it is formed on the abutment surface on one of bottom or top, and contacts relative abutment surface to close and to seal this passage.But this mast or connector will be installed to the bottom or the deformation region on top, thereby when cavity indoor pressure surpassed predetermined threshold, this mast or connector deformation were limiting an opening, through the outlet of can flowing through of this opening fluid.

To depend on related application scenario for opening the predetermined minimum pressure that must reach in the outlet valve chamber.One skilled in the art will know that the characteristic that how to change this strain surface, for example can be by selecting suitable deformable material or changing this surperficial mode of manufacturing (for example, strengthening ridge) by being provided with.

When the elastically deformable of main body part is deflected in the chamber and during compression chamber, only discharges through outlet in order to make fluid from initial elasticity bias voltage form, need on the inlet of spray nozzle device or in the inlet, a check valve be set.

Can adopt any suitable inlet valve.

Inlet valve only can be set to open and to allow fluid inflow chamber indoor (the elastically deformable part that for example ought be applied to chamber discharges with the pressure of compression chamber, and chamber capacity is when increasing when partly returning to initial elasticity bias voltage form along with elastically deformable) when following when cavity indoor pressure drops to predetermined minimum threshold.In these cases, inlet valve can be a clack valve, and it comprises the strain flap that is positioned on the inlet opening.The best elasticity of this flap is against on the inlet opening partially, and produces deformation and allow fluid to flow into chamber to allow cavity indoor pressure to drop to predetermined minimum threshold when following.Yet At All Other Times, inlet will be closed, thereby prevent that fluid from flowing back into inlet from chamber.Particularly preferably be, this strain flap forms the one of the elastically deformable part of the main body that limits chamber and extends form.Also particularly preferably be, the bottom limits inlet, and the elastically deformable part of main body is formed by top.Therefore, preferably, top comprises the strain flap, and this flap extends covering inlet opening and extends to chamber in described chamber, and forms inlet valve.

In addition, flap not elasticity supports the inlet opening partially, can be positioned on the inlet opening, and it only can be configured to when the chamber compression and wherein compresses inlet during the pressure increase.

Yet the clack valve that simply is provided at elastic biasing on the inlet opening has brought problem.Especially, the long-term elasticity limit that can surpass the formed material of flap of using, this will cause its cisco unity malfunction.Especially in the embodiments of the invention that flap is partly formed by thin rigid material this problem can appear, although this problem is light and can be because flap deformation and taking place during the chamber compression also this problem can take place when valve is opened in flap deformation for the flexible material degree.Therefore, fluid can flow back into the container from chamber through inlet.

In view of these reasons, preferably, clack valve comprises many counterparts.Particularly preferably be, inlet has the rising antelabium that extends around the ingate, and the strain flap is in abutting connection with this antelabium, with around the inlet tight seal.Provide antelabium to guarantee to utilize flap to obtain excellent contact.In the very little embodiment of antelabium, need provide one or more additional supporting rib in a side of inlet opening, to guarantee forming good sealing and to prevent that antelabium from damaging.

Further preferred embodiment is that flap has projection or obstruction in its surface.It is a bit of that this projection or obstruction extend into the inlet opening, and seal with further enhancing in abutting connection with lateral margin.

Also preferably, the inlet opening of chamber is positioned at the higher position of chamber, thereby fluid flows into chamber through inlet, drops to keep or storage area.Away from the main fluid maintenance/storage area of chamber, prevented that fluid from remaining in the inlet valve top for a long time by the opening that effectively will enter the mouth, thereby reduced along with the possibility that takes place time lapse to leak.

Also preferably, second strengthens the apparent surface of flap or parts contact resilient distortion flap, to impel it closely in abutting connection with the inlet opening.Also preferably, second strengthens flap on a part of apparent surface or near the apparent surface of a part of apparent surface's local contact resilient distortion flap, with the pressure at right angle of the main valve clack on the maximization hole, wherein this part apparent surface covers the ingate.This helps further to keep the globality of sealing.

Dispenser nozzle also can have locking device, in case the fluid stopping body is discharged suddenly.

In these embodiments, locking device will be the integrated component of main body, will can not be the separate part that is connected to main body.For example, this locking device can be hinge bar or hinge member, and its one is connected to the part (for example, bottom or top) of main body, and can rotate to certain position, opens thereby this hinge bar or parts prevent outlet valve.

This locking device can comprise rigid cap, and the top that it is positioned at the elastically deformable part of main body prevents that this locking device is compressed.This lid can be hinged to dispenser nozzle, folding when needed.In addition, this rigid cap can be a top cover slidably, its can be in use sliding compression chamber downwards.This lid can reverse with locking, thereby prevents actuating suddenly of locking apparatus.

This device can also comprise leakage hole, and air can flow through this leakage hole, with pressure reduction between the inside and outside environment of compensation vessel.In some cases, the gap that the installation place occurs between dispenser nozzle and container will leak gas simply, but this is not preferred, because also can leak when container is squeezed or shake.In a preferred embodiment, dispenser nozzle also comprises steam leak-off valve, check valve just, and it can allow air to flow into container, if but be inverted and can prevent that any fluid from letting out from container.Any suitable one-way valve system can adopt.Yet preferably, steam leak-off valve also can be integrally formed in the main distributor, perhaps more preferably, forms between two parts of main distributor.

Most preferably, steam leak-off valve is formed between the top and bottom that limits the dispenser nozzle chamber.

The specific embodiment

Below in the description of accompanying drawing, in different figure, identical Reference numeral suitably representation class like or corresponding part.

Fig. 1 illustrates first embodiment of dispenser nozzle of the present invention.Be used for comprising main body 100 that this main body is formed by two parts, just bottom 101 and top 102 with this device of Sprayable distributing fluids.Bottom 101 and top 102 are connected with each other by collapsible attaching parts 103.

The bottom 101 is coupled to (not shown) on the container, is inhaled into described device or distributes from described device to allow to be stored in fluid in the described container during use.

In this embodiment, main body 100 is made by single rigid plastic material in independent molded operation.This device can be molded as structure shown in Figure 1, and top 102 is folding around attaching parts 103 then, and is assembled to the upper surface of bottom 101, thereby forms the spray nozzle device that assembles.In case bottom 101 and top 102 are assembled together, the adjacent part/surperficial 101a of the part 102a of the lower surface on top 102 upper surface of 101 then in abutting connection with the bottom.The sunk part 101b and the 101c of bottom 101 upper surface and the sunk part 102b and the 102c that are formed on the correspondence in the lower surface on top 102 aim at respectively, limit two independent internal chamber.

Each chamber comprises ingate 104a and the 104b that is formed on the bottom.Each ingate is provided with depression 105a and 105b separately, as shown in Figure 1.When top 102 is assembled to the bottom 101 the time, the flap 106a of elastically deformable and 106b are received in respectively among depression 105a and the 105b.Flap 106a and 106b elastic biasing, the opening with ingate 104a and 104b offsets respectively, thereby forms inlet valve.Therefore, only when the pressure in the ingate surpassed cavity indoor pressure, fluid could flow in two chambers, thereby described flap departs from the opening of ingate 104a and 104b, allowed fluid to flow into chamber.Each ingate 104a is connected to different fluid sources with 104b, such as installing independent compartment in the container that is connected.In addition, a chamber can suck air (or gas of other form) from container or external environment condition.At latter event, air intake can simply be formed in the device main body, sucks from external environment condition to allow air.

Outlet comprises exit passageway and outlet opening, when abutment surface 101a and 102a contact, is limited by this abutment surface 101a and 102a.This passage forms by groove 106,107 and 108 is aimed at groove 109,110 and 111 respectively, and the chamber that forms in the exit passageway 112 and 113 forms with depression 114 and 115 alignings respectively by cave in.

Therefore, the chamber that the fluid that distributes from the chamber that depression 101b/102b forms between the operating period forms by alignment recess 112/114 entered the chamber that forms by alignment recess 113/115 then before discharging through outlet opening.The fluid that distributes from the chamber that depression 101c/102c forms between the operating period enters the chamber that alignment recess 113/115 forms, at this it and mixed before discharging from the fluid that other chamber distributes through outlet opening.

Provide the chamber that forms in the passage to be found and help to make the drop division that from dispenser nozzle, distributes, thereby can produce thin spraying.

The exit passageway of deriving from each chamber can also comprise the outlet valve (not shown), and it is positioned at chamber upstream, thus only when cavity indoor pressure during above a predetermined minimum threshold fluid could discharge.Can form valve by other parts in elastically deformable flap or the exit passageway, other parts in elastically deformable flap or the exit passageway can be that the pathway closure position begins deformation from the initial elasticity offset position, to limit an opening, when cavity indoor pressure was in or surpass minimum threshold, fluid can flow through this opening.

This device preferably also comprises sealing device, combines closely to guarantee top and bottom.In the embodiment shown in fig. 1, plastic cement (plastic) can be annotated on the junction by mould, suitably seals closely obtaining.In addition, a part can have ridge, and it is around depression and the side that limits those groove/depressions of exit passageway, and with the groove sealed engagement of the correspondingly-shaped that on relative abutment surface, forms.This ridge will closely cooperate with corresponding groove and be in the same place, to help bottom 101 and top 102 are closely kept in abutting connection with ground mutually.Projection and groove also form a kind of sealing, in case the fluid stopping body is from chamber or exit passageway spills and seepage between top 102 and bottom 101.

In optional embodiment, steam leak-off valve can be mast or the flap that is positioned at a hole,, when pressure reduction occurs, this hole can strain opening passage, thereby allow air to flow into the container from external environment condition.

During use, exert pressure by part 102b on the upper surface of the device that assembles and 102c, fluid can be discharged from dispenser nozzle.These parts form the elastically deformable part of main body.When applied pressure was removed, part 102b and 102c got back to the initial bias state, thereby made chamber capacity increase, and fluid injects each chamber through inlet 104a and 104b.

In certain embodiments, a chamber, for example the chamber that forms of alignment recess 101c/102c comprises air, the pressurized together of chamber causes air stream to be discharged from this chamber, thereby and the liquid that distributes of another chamber mix.This mixing will make the breakup of drop, and help liquid to divide timing to form thin spraying through outlet.

Fig. 2 illustrates an optional embodiment of the present invention, and its form with spraying is sprayed two kinds of liquid simultaneously.The many aspects of this embodiment all are similar to embodiment shown in Figure 1 (adopting same reference numerals to represent).Yet, have some differences.At first, top 102 is connected to bottom 101 from the front, rather than connects from the side as shown in Figure 1.Therefore, be assembled to bottom 101, can turn down top 102 simply, thereby form the dispenser nozzle that assembles by bending/folding attaching parts 103 and with it.

Device shown in Figure 2 can also be configured to spray separately two kinds of liquid, thereby by merging these two kinds independently liquid, they are only in the dispenser nozzle external mix, and this needs for some application examples.Certainly can understand, in optional embodiment, exit passageway can merge in the exit passageway of embodiment shown in Figure 1 in a similar fashion.

Exit passageway can also be different, and promptly passage is aimed at by groove 201 and 202 and formed.This passage extends to an eddy chamber, and this chamber is aimed at by semi-cylindrical canyon 203 and 204 and formed.Therefore, the fluid that distributes from each chamber between the operating period is along this channel flow, and enters this eddy chamber, thereby before outlet opening is discharged rotating flow is being incorporated in the fluid stream.Eddy chamber is well known in the art, and can fluid before outlet is discharged once more the convection cell droplet divide.

Another difference that is different from embodiment shown in Figure 1 is that embodiment shown in Figure 2 also comprises two air release valve.Form air release valve by valve member 205 and 206, valve portion 205 and 206 is formed on the lower surface on top 102, and is received in respectively in opening 207 and 208 when the assembling nozzle device, and opening 207 and 208 is formed on the abutment surface 101a of bottom.Opening 207 and 208 also defines some passages, and in the spray nozzle device that assembles, air can enter the container from the outside through these passages.The tip of these elastically deformable parts has an enlarging edge, the inwall of its this opening of edges abut, thus form gas-tight seal.If because of fluid exists pressure to reduce from the spray nozzle device discharge, then the pressure reduction between internal tank and the external environment condition has caused the inside deformation of enlarging edge of these parts, thereby allows air to flow into container from external environment condition.In case this pressure reduction is able to balance, then this enlarging edge is just got back to initial elasticity bias voltage form, to prevent the air opening of further flowing through.Should be understood that if container is inverted, product can not be through this ovfl of these elastically deformable parts, for example any pressure that applies by squeeze receptacle can promote the wall that this opening edge more closely is contiguous to opening simply.

In an optional embodiment, steam leak-off valve can be mast or the flap that is positioned at a hole, when pressure reduction exists this hole can strain opening passage, thereby allow air to flow into the container from external environment condition.

In another optional embodiment, the top 102 of elastically deformable comprises a finedraw, and it is positioned at the top of the opening that is similar to opening 207 and 208.When pressure reduction existed, this seam can be opened.

In another optional embodiment, valve member can be mast or stopper, and it is formed on the top 102, blocks the opening that forms in the bottom, and only when top just mobile during to lower compression, with the distribution of fluid in the actuation chamber.

Another difference is that top comprises ridge 209, and it is around each depression (102b and 102c), and each side of extension slot/depression 201-204, and wherein groove/depression 201-204 limits each exit passageway.When top and bottom were combined together, these projectioies were received in the sealed engagement that forms with corresponding groove 210, and wherein corresponding groove 210 is formed on the upper surface of bottom 101.Formed sealing has prevented that any fluid from leaking from chamber, perhaps prevents oozing out of the junction of exit passageway between top 102 and bottom 101.This ridge also extends through exit passageway, forms the outlet valve member.This part of projection can form a clack valve, only when reach predetermined minimum threshold in each chamber, this clack valve can deformation with the permission fluid along each channel flow.Other the institute sometimes, this valve member is closed this passage.

Fig. 3 illustrates another embodiment of the present invention, and it is similar to embodiment shown in Figure 2, and difference is that it is not the form distributing fluids with spraying, but dispenser nozzle 301 is configured to distributing fluids group (such as viscous fluid).Therefore, this device comprises straight exit passageway, and it is wider than the passage of previous embodiment, does not also have any chamber.

Suction distributor shown in Fig. 1-3 all has the projection of two general dome shapes on the upper surface of the device that assembles, it must be pushed by the operator, also makes contents wherein discharge through outlet with compression chamber.Potential problems of this project organization are, the operator need push this dome with finger, and this just needs the operator that its finger is placed on correct position, fully compresses to guarantee chamber.Also find, need a bigger pressure this dome could be pressed into enough degree, this has just produced a shortcoming again, especially usually needs the user to utilize such as the different parts of the hand of palm even utilizes ancon or forearm is exerted pressure, to actuate common suction distributor.In these examples, for example utilize palm to impel fluid to discharge from device, fully compress this dome and can bring very many problems.

Therefore, of the present invention another improves embodiment and is developed, and by the actuator surface of rigidity or substantially rigid is provided, makes the operator can use any position of hand or arm to actuate, and this embodiment is illustrated among Fig. 4 A-4D.Fig. 4 A illustrates and is unkitted the embodiment for preparing, and just, bottom 101 and top 102 are separated from each other.By bent/collapsible attaching parts 103, bottom 101 can be connected to top 102.This bottom comprises two outlet opening 401a and 401b, outlet opening of each chamber just, and this chamber forms by alignment recess 101b/102b and 101c/102c respectively.Each outlet receives plug members 402a and the 402b that is formed on the top 102 respectively.

As mentioned above, top 102 can rotate to the top of bottom 101 upper surface and be assembled to the upper surface of bottom 101, thereby forms the spray nozzle device that assembles, shown in Fig. 4 B.With reference to Fig. 4 B, can see that this dispenser nozzle that assembles comprises a bigger actuator surface as upper surface, this upper surface forms by the part 102b and the 102c on top.

With reference to Fig. 4 C, show along the cross-sectional view of the line X-X ' of Fig. 4 B, can see, in the structure that assembles, around the projection 403 that the periphery of the regional 101b of bottom 101 extends be received in and groove 404 between sealed engagement in, to form being tightly connected between bottom 101 and the top 102, wherein this groove 404 is formed in the top 102.Elastically deformable flap 106a is also received among the depression 105a, and to form inlet valve, wherein this is recessed to form in the bottom and surrounds inlet 104a.

Top 102 also has two parts 405, and it comprises groove 405a, and this groove receives the end of two pivot protrusion 406 that form on 101 upper surfaces of bottom.This structure makes top 102 to pivot with respect to the bottom, thereby the part 102b on top can move with compression chamber 410, shown in Fig. 4 D to the part 101a of bottom 101 upper surfaces.

First/actuator surface the 102b/c of apparatus main body is formed at top.By the elastically deformable sidewall 411 of bottom, the second elastically deformable part that can the generator main body.Wall 411 is resiliently biased, and having the structure shown in Fig. 4 C, thereby actuator surface 102b 101 removes from the bottom, and chamber 410 obtains heap(ed) capacities.

When pressure is applied to actuator surface 102b with the direction of arrow 415,411 deformation of elastically deformable wall, thereby the actuator surface to the part 101b of the upper surface of bottom 101 off normal, thereby compression chamber.The pressure that increases in the chamber makes that stopping up 402a removes from outlet 401a, thereby fluid is discharged from chamber.Any suitable outlet valve described here can replace stopping up 402a.When applied pressure discharged, wall 411 was got back to initial elasticity bias voltage form, and shown in Fig. 4 C, thereby the capacity of increase chamber reduces the pressure in it, made that more the multithread body is through inlet 104a intake chamber.

Stop up 402a effectively as precompression valve, only guarantee when its internal pressure be enough to obstructions when outlet opening is removed fluid ability from chamber 410 discharges.In order to make fluid by stopping up 402a, it is hollow preferably, thereby it can deformation limit a passage, perhaps must have enough spaces above stopping up, and stops up 402a like this and can move, so that it can be removed from outlet opening.
