Description

Dispenser nozzle

Technical field

The present invention relates to a kind of dispenser nozzle, more specifically still not exclusively, the present invention relates to a kind of dispenser nozzle of pumping action, and the method for making this dispenser nozzle.

Background technology

The dispenser nozzle of pumping action generally be used to provide a kind of can be in response to operator's device of distributing fluids and from vessels not under pressure or other fluid source to the operation of spray nozzle device, described fluid is viscous fluid particularly, for example soap, shampoo, face cream etc.

Traditional pump-action nozzle devices is suitable for being assembled to outlet of container, and comprises an internal chamber, and when the actuator of spray nozzle device was operated, described internal chamber can be extruded.The extruding of described internal chamber causes pressure to increase, and the pressure increase can force the liquid that exists in the chamber to be assigned with by the device outlet.In case after the liquid of predetermined was assigned with, when perhaps chamber was extruded to abundant degree, actuator can the person of being operated discharge subsequently, chamber is allowed to reexpand.Reexpanding of described chamber causes that the internal pressure in the chamber reduces, and pressure reduces and causes that next more liquid are back to the chamber from the container that links by inlet.Check valve is set at entrance and exit, to guarantee that fluid is just by exporting chamber discharge internally and being introduced into chamber by inlet.

Actuator is the part of the main body of spray nozzle device normally, this part can be depressed, and next can the person of being operated discharge (usually being known as the pump spray nozzle device), or next the operator can draw then and discharge, with the trigger (usually being known as trigger-actuated nozzle arrangements) that causes that respectively chamber is extruded and then expands.

The tradition pump-action nozzle devices has many shortcomings.At first, many conventional apparatus are tended to extremely complicated in design, and generally include a plurality of different members (being generally 8 to 10 independent members in the pump spray nozzle device, is 10 to 14 independent members in trigger-actuated nozzle arrangements).As a result, because make the needed material quantity of independent member, and related assembling process, so the manufacturing cost of these devices is very high.Secondly, many conventional apparatus are tended to volume big (this has increased the cost of raw material again), and this volume part usually is disposed in the inside of the attached container of this device.This produces following shortcoming, and promptly spray nozzle device has taken the part of internal tank volume, and this can utilize space itself just to become a special problem in regard to very limited small container at internal tank.At last, the pumping action device size is also stipulated to a certain degree by the size of its attached container.Like this, plant bulk just is limited in the small container usually, and particularly in having the container of little neck, and this has limited the quantity of the pressure that device produces and the quantity of the fluid that can be assigned with, and therefore, this performance to device is all very harmful.

Therefore, need a kind of pump-action nozzle devices, this device:

(i) structurally simpler;

(ii) can utilize littler member; With

(iii) operate and realize effectively its function easily.

More the example of the dispenser nozzle of simple structure is disclosed in EP0442858A2, among EP0649684 and the US3820689.Disclosed dispenser nozzle is to be formed by two independent members in essence in these publications, and these two independent members are fixed together, to determine an internal chamber that has the inlet that is equipped with inlet valve and be equipped with the outlet of outlet valve.One is the base portion that is formed by rigid material in these members, and another member is the strain part, and this strain partly is fixed to the base portion upper surface, and determines internal chamber with base portion, and forms inlet and outlet valve parts.This strain partly provides a kind of internal chamber to be extruded to distribute the device of the fluid that wherein exists by it.

Can provide some advantages though be fixed to the scheme on the strain top of rigid base, for example can provide soft tactility, and easy deformation is beneficial to pressing cavity, some shortcomings are also arranged, that is:

(i) because the different attribute of two kinds of materials, so be difficult to two members are firmly held in together;

The (ii) pumping action conventional pump distributor (especially, pumping action is not the common ON/OFF effect relevant with the conventional pump distributor) that is different in essence and on market, can obtains; With

(iii) two members need be assembled together the dispenser nozzle that assembles with formation.

Summary of the invention

The invention provides a kind of technical scheme that can solve at least some relevant problems of known dispenser nozzle, first aspect, the invention provides a kind of pump-action dispenser nozzle that is suitable for making the fluid that is stored in the fluid source in use to be assigned with by described nozzle, described nozzle has the main body of the internal chamber of limiting, described internal chamber has entrance and exit, fluid is drawn in the described chamber by described inlet, the fluid that is present in the chamber is discharged from from nozzle by described outlet, described inlet comprises inlet valve, when described inlet valve is suitable for below the pressure in the chamber drops to pressure in the fluid source at least the minimum threshold amount, only allow fluid to pass through inlet and flow into chamber, described outlet comprises outlet valve, described outlet valve is configured to surpass the exit external pressure at least during the minimum threshold amount when wherein pressure, only allow fluid to flow out chamber and be discharged from from nozzle, and wherein, at least a portion that limits the main body of described chamber is configured to:

(i) applying in response to pressure, can flexibly be deformed to expansion or deformed configurations from the initial elasticity voltage biasing structure, therefore, when the described parts of main body when described initial configuration is deformed to described expansion or distressed structure, the volume of the described chamber that is limited by the described parts of main body is reduced, minimizing on the described volume causes that the pressure in the chamber increases, and causes that fluid is discharged from by outlet valve; And

(ii) next, when institute's applied pressure is removed, can get back to its initial elasticity voltage biasing structure, cause that therefore chamber volume increases, pressure wherein reduces, to such an extent as to fluid is drawn in the chamber by inlet valve;

It is characterized in that this device main body is formed by rigid material or flexible material fully, perhaps form with two injection molding methods.

Here the main body that " two injection molding method " refers to spray nozzle device comprises two parts, first parts are undertaken molded in the original moulded step by first kind of material with framework that is used for another described parts or base portion in the described parts, can be molded on the described base portion with the identical or different second kind of material of described first kind of material, with the finishing device main body.Two injection molding methods are known in the art.

Term " fluid " is used to refer to any material that can flow here.Therefore, though in use the fluid that aspirates by dispenser nozzle can be different fluids usually, in some cases, fluid can be gas or admixture of gas, for example air.For example, little pump can be formed on the sidepiece of packaging for foodstuff or sack, with the device that provides a kind of air can be drawn out of by it.

Dispenser nozzle device of the present invention has solved and the relevant the problems referred to above of many traditional pump-action dispenser nozzle, it provides a kind of extremely simple in design and generally include the device of no more than six independent members, and these independent members can be assembled in the spray nozzle device that assembles with formation together.In a preferred embodiment, described device comprises no more than three members, perhaps more preferably, no more than two independent members, perhaps even more preferably, this device is formed by an integrally formed member." independent member " refers to, and member is bonded never in any form, and in other words, they are not monolithic moldings (but each independent member can comprise one or more global facilities or part) each other.

In dispenser nozzle of the present invention, the key that reduces the number of components is such discovery, that is, even when nozzle is prepared by a kind of rigidity or flexible material fully, the member that is necessary can be in apparatus main body monolithic molding.For example, chamber, inlet, inlet valve, outlet and outlet valve can reduce the needs that comprise the independent member that all causes member increase and assembly cost increase thus by main part limitation.

Rigidity and flexible material can be any suitable materials that can make dispenser nozzle.For example, it can be a metal material, for example aluminium foil, perhaps flexible material, for example rubber.But preferably, apparatus main body is shaped by rigidity plastics or flexiplast fully.

Pump-action dispenser nozzle is preferably formed by single kind rigidity or flexiplast.

Term " rigidity plastics " in case here be used to refer to is molded into predetermined form and just has high rigidity and high-intensity plastics, but by reducing plastics thickness, it also can become soft more or can local elasticity's distortion.Like this, the plastics in thin cross section can be provided to form at least a portion that limits chamber and be configured to main body that can strain.

Term " flexible material " here be used for expression itself be flexible/can strain so that make the elastic displacement of main body at least a portion can help the plastics of pressing cavity.The flexible degree of plastics can depend on the thickness at the plastics in any given area or zone.This " flexiplast " is used in the preparation of shampoo bottle for example or shower gel container.In the manufacturing process of dispenser nozzle of the present invention, main part is formed by the plastics in thick cross section, and providing the rigidity that needs to this structure, and other part can be made up of so that the deformation characteristic of necessity to be provided the plastics in thin cross section.When needing, if need extra rigidity at some area, can occur the framework in thicker cross section so, this is commonly referred to as ribs.

Use single advantage of planting material to be, whole dispenser nozzle can be molded in molded operation of an instrument neutralization, and this can further be described below.

Preferably, fluid source is the attached or integrally formed with it container of dispenser nozzle of the present invention.

The dispenser nozzle outlet can be any form.But preferably, outlet comprises an exit passageway, and this exit passageway extends to the outlet opening of device from chamber.

The dispenser nozzle main body

Preferably, pump-action dispenser nozzle comprises two or more interconnecting members, and when coupling together, these interconnecting members can limit chamber.Particularly preferably be, the chamber of dispenser nozzle is limited between two interconnecting members.

In addition preferably, at least two interconnecting members that also limit chamber betwixt limit dispenser nozzles outlet at least a portion or from the passage of chamber exit.

Most preferably, two parts of the qualification chamber of the main body of dispenser nozzle are a base portion and a top.Base portion preferably is adapted to pass through appropriate device and is assembled to vessel port.For example, it can be the form of thread cap, and described thread cap can be screwed on the container neck opening.Furtherly, except the part of the main body that form to limit chamber, base portion also preferably limits inlet and from the part of the passage of chamber exit.

Top is suitable for being assembled on the base portion, so that between them, limit chamber, and in a preferred embodiment, also limit the exit passageway and/or the outlet opening of distributor.In specific embodiment of the present invention, base portion and top also limit oral pore.In addition preferably, the strain part of the main body that limits chamber is formed at top.

The part that is configured to the main body of strain can be the rigidity plastics in thin cross section, when exerting pressure, the rigidity plastics strain in described thin cross section is with pressing cavity, then, when applied pressure was removed, described rigidity plastics was got back to its initial elasticity voltage biasing structure again.As selection, the part that is configured to the main body of strain can comprise that is deformed the part that is rigidity basically that part is surrounded, partly be out of shape so that be applied to the strain of the pressure of rigid element around can causing, and rigid element can be shifted with pressing cavity.For example, strain part on every side can be similar to bellows (bellow), in other words, rigid element is comprised that the distorted sidewall of a plurality of fold segments of being made by rigidity plastics surrounds, be formed at when exerting pressure, can cause that the folded part of sidewall flexibly presses together to reduce the volume of chamber to rigid element.In case remove institute's applied pressure, sidewall is just got back to its initial configuration.

Particularly preferably be, at least two parts of main body are made by identical materials, and interconnect by means of the hinged or foldable connection member.This is molded together two parts in single molded operation, be rotated to contact with each other the dispenser nozzle (for example top can be transferred to base portion and contact) that assembles with formation then.

Two parts of main body for good and all are fixed together, for example by ultrasonic bonding or thermal weld.If base portion and top will be molded or weld together, so preferably, they are made by compatible material.But as previously mentioned, preferably, main body is formed by single material of planting.

As selection, two parts can be formed under the situation of welding sequence closely/go up each other with formation nozzle (for example, stinging the part that is connected by providing) facing to being assembled to.For example, the edge of parts can be configured to be assembled in the maintenance groove of another parts, to form dispenser nozzle.

Select as another kind, a kind of compatible plastics can be molded in the joint of two parts, to hold them in together.This can by in an instrument simultaneously molded two members realize, thereby in instrument, they are joined together to form dispenser nozzle device, then, around their molded suitable plastics so that two parts are kept together.

In certain embodiments, two parts can interconnect releasedly, so that in use, they can be separated with cleaning chamber and/or outlet.

For most applications, distributor all need be made by rigid material, so that necessary strength to be provided, and two parts can be stung cooperate or welds together.In these cases, the crushed element of main body tends to only just be out of shape when applying certain minimum threshold pressure, and this makes pumping action more as the ON/OFF effect of relevant traditional pump-action dispenser nozzle.But under some applicable cases, flexible material is preferred.The example of these applicable cases comprises such embodiment, and wherein, dispenser nozzle and associated container monolithic molding, described container for example can be the form of pouch, and perhaps the fluid that will supply is stored in the device rather than in the independent container.

Outlet valve

In order to make function the best, be necessary that outlet provides a check valve to chamber, perhaps the chamber outlet is suitable for playing the effect of check valve.Just be assigned with (because the displacement that is begun from its initial elasticity voltage biasing structure by the strain wall causes that the internal chamber volume reduces) when check valve makes the product that is stored in the chamber only obtain predetermined minimum threshold pressure in chamber, and all close outlet At All Other Times to form hermetic seal at all by outlet.Closing of valve can prevent when the pressure of the strain part that is applied to main body is released when pressure is lower than predetermined minimum threshold in the chamber, air sucks back in the chamber by outlet, and because the strain wall presents its initial elasticity voltage biasing structure again, so chamber volume increases.

Any suitable check valve assembly can be provided in outlet, and described check valve can form hermetic seal.Preferably, valve is formed by the member of the main body of dispenser nozzle.

In the preferred embodiment of the present invention, outlet opening comprises that one extends to the exit passageway of outlet opening from chamber, preferably, and exit passageway or its part and/or outlet opening are limited between the base portion and top of dispenser nozzle at least.More preferably, passage is limited between two abutment surfaces on base portion and top, and at least a portion of one can face toward apparent surface's fexible bias pressure in the abutment surface, so that form unidirectional outlet valve in passage or in outlet opening.In this, the fexible bias pressure surface forms a lid in exit passageway and/or outlet opening, having only when the pressure in the chamber is enough to cause the distortion of fexible bias pressure abutment surface away from adjacent surface relatively and when forming the open groove that a fluid can flow out by it thus from chamber, and this lid is just opened and allowed fluid to be assigned with from chamber.In case pressure drops to predetermined minimum threshold when following, its fexible bias pressure structure can be got back in the fexible bias pressure surface, and closing passage.

Particularly preferably be, be suitable for being out of shape whole formation of strain part with at least a portion with the main body that limits chamber of the fexible bias pressure abutment surface of opening outlet valve away from the apparent surface.

In the embodiment that the strain part of the flexibility of exit passageway/valve is made by the rigidity plastics in thin cross section, resistance is not enough to provide the minimum pressure threshold that needs.In these cases, the thick rib plastics that extend through passage can be formed so that necessary strength and resistance to be provided in exit passageway/valve.As selection, the rigidity ribs may be provided in the part top of exit passageway/valve.

In a selectivity preferred embodiment, outlet valve forms with the elastic deformation component who effectively cuts out with seal channel by extend through outlet groove.This element is installed on the device along an one edge, and allows its another edge (preferably opposite edges) freedom, free end be configured to can be shifted when the pressure in the chamber surpasses predetermined minimum threshold.When pressure is lower than predetermined minimum threshold, free end in abutting connection with the outlet groove the surface to form a sealing with it.But when pressure surpassed predetermined minimum threshold, the free end of this element began displacement from the abutment surface of groove, and to form an opening, the fluid that exists in the chamber can flow to outlet by this opening.Preferably, the elastic deformation component is arranged in a chamber that forms along the length of outlet groove or passage.More preferably, the abutment surface that when pressure is lower than minimum threshold, forms sealing with described element free end with point that described element free end contacts on tapered or slope shape.This provides a kind of dot encapsulation contact, and a kind of effective seal more is provided.What will recognize certainly is, the inclined plane of abutment surface or taper surface must be arranged to will be convenient to when pressure is lower than predetermined minimum threshold in the chamber, elastic deformation component's free end can contact described inclined plane, but when predetermined minimum threshold was exceeded, described free end expansion was away from described inclined plane.

As selection, valve can be formed in base portion or the top pillar or the obstruction on one the abutment surface, described pillar or stop up and can contact relative abutment surface to close and seal channel.The deformed region on base portion or top is installed in described pillar or obstruction, so that when the pressure in the chamber surpassed predetermined minimum threshold, pillar or obstruction can be out of shape to limit fluid can pass the opening that outlet is flowed out by it.Make pillar or stop up the needed pressure of displacement and can be set at any desirable level (thereby form pre-squeezing valve effectively, described pre-squeezing valve can guarantee that fluid only just can be discharged under desirable pressure).

In another preferred embodiment of the present invention, dispenser nozzle is configured so that fluid essentially horizontally is assigned with, and perhaps more preferably, being convenient to fluid can be assigned with on downward direction.Under latter event, outlet opening is down opening preferably, and this opening is limited by the base portion with an exit passageway, and described exit passageway leads to this opening from chamber, and described chamber is limited by the upper surface of base portion and the relative lower surface on top.Except limiting oral pore, base portion also can limit the part of the downward extension of passage.In addition preferably, leading to down, (in other words the aperture down or the downward extension of the passage in aperture are formed with the minimum internal volume, passage has minimum length, so that volume is as far as possible little, perhaps obstruction can be full of whole aperture volume, so that be retained in any fluid displacement in this zone).This provides following advantage, and promptly outlet opening forms vertically, and does not need side to be used for forming it in instrument.For example, turn forward, and keep antetheca vertical, just the hole that can obtain to turn forward by the rear wall that makes the aperture.This structure utilization be the instrument of not being with the side effect.In addition, minimized volume has reduced the problem that the fluid that is retained in the passage oozes from outlet after use, and makes because the choking phenomenon that exists the fluid that becomes dry to cause minimizes.In these embodiments, outlet valve preferably forms by the obstruction that is formed on the lower surface of top, in the outlet opening that described obstruction extends in the passage of downward extension and/or limited by base portion.The obstruction that is installed to the strain zone is configured to when the pressure in the chamber surpasses predetermined threshold, can be from downward extension passage and/or outlet opening displacement, get back to its fexible bias pressure structure then closing outlet, and prevent that air is drawn in the chamber by outlet.

The predetermined minimum pressure that needs depends on relevant applicable cases, and those skilled in the art know how to revise the attribute (for example reinforcing protrusion by being provided with) on strain surface by the mode of selecting suitable elastic deformation material and change to make the surface.

Inlet valve

In order to ensure when by main body strain part is displaced to when chamber is extruded from its initial elasticity voltage biasing structure, fluid just is discharged from by outlet, be necessary to provide one be arranged on the spray nozzle device porch or enter the mouth in check valve.

Any suitable inlet valve can be used.

Inlet valve can be suitable for having only when the pressure in the chamber and drops to predetermined minimum threshold when following, just open and allow fluid to flow in the chamber (Here it is is released when the pressure of the strain part that is applied to chamber with pressing cavity, so and because the situation that the strain part presents its initial elasticity voltage biasing structure chamber volume again when increasing).In these cases, inlet valve can be a clack valve, and described clack valve is made up of a strain lobe that is arranged on the inlet.Described lobe preferably is resiliently biased on the inlet, and is suitable for distortion, so that drop to predetermined minimum threshold when following when the pressure in the chamber, can allow fluid to be drawn in the chamber by inlet.At All Other Times the time, inlet can be closed, and prevents that thus fluid from flowing back into inlet from chamber at all.Particularly preferably be, the strain lobe forms a whole extension of the strain part of the main body that limits chamber.Particularly preferably be in addition, base portion limits inlet, and the strain part of main body is formed by top.It is therefore preferable that top comprises the strain lobe, described distortion lobe extends the inlet opening that leads to chamber with covering in described chamber, and forms inlet valve.

As selection, described lobe can not be to be resiliently biased on the inlet opening, but is disposed in inlet opening top, and is configured so that to have only when chamber and is extruded, and when pressure wherein increased, it just was pressed onto on the inlet.

But, in this simple scheme of resiliently biased clack valve on the inlet opening also some problems can appear.Especially, after certain hour, the elastic limit of materials that forms lobe may be exceeded, and this may cause that lobe can correctly not play effect.This problem can appear in the embodiment of the invention that lobe forms by the rigid material in thin cross section especially, though it also is applicable to flexible material on less degree, and because when chamber is extruded, and be out of shape when opening valve when lobe, lobe can deform, so also the problems referred to above can take place.As a result, fluid may return from chamber by inlet and drain to the container.

So preferably, clack valve comprises many alter modes.Particularly, preferably, the antelabium that inlet has a projection, described antelabium extends around the inlet opening, and the strain lobe is adjacent to antelabium, to produce a tight seal around inlet.Provide antelabium can guarantee to utilize described lobe to obtain excellent sealing.In the very little embodiment of antelabium, it may be necessary providing one or more additional support ribs at inlet opening either side, guaranteeing forming correct sealing, and prevents that antelabium is impaired.

Another preferred feature is that lobe has one and is formed on its lip-deep protuberance or obstruction.Protuberance or obstruction extend to very short distance in the inlet opening, and the adjacent sides edge is with the sealing of further raising formation.

In addition preferably, the inlet opening that leads to chamber is disposed in higher position in the chamber, so that fluid flows into chamber by inlet, and drips to downwards in retaining zone or the storage area.By making the main fluid retaining zone/storage area of inlet opening effectively, can prevent that fluid is positioned at the inlet valve top over a long time, and reduce the possibility that any leakage took place in the past along with the time thus away from chamber.

In addition preferably, the another kind of apparent surface who strengthens lobe or parts contact resilient distortion lobe is to impel strain lobe and the tight adjacency of inlet opening.In addition preferably, described another strengthened lobe in this part of apparent surface's covering inlet opening or near the apparent surface of contact resilient distortion lobe on its position, with the vertical pressure of maximization main lobe on opening.This also can help to keep the integrality that seals in addition.

Locking device

Spray nozzle device also provides a locking device, in case fluid stopping body accident is assigned with.

Preferably, described locking device and main body monolithic molding.For example, locking device can be hinge bar or parts, described hinge bar or parts integrally are connected on the part (for example base portion or top) of main body, and (for example can be transferred to position that actuator can not the person of being operated depresses, actuator engages described bar or parts, makes a part of strain of the main body that limits chamber to prevent the person of being operated from depressing).

Locking device also can comprise rigid cap, and described rigid cap can be placed on the strain part top of main body, is compressed to prevent it.Described lid can be connected on the dispenser nozzle by a hinge, so that it can be folded when needed.As selection, rigid cap can be a slide lid, and described slide lid can be to lower slider with pressing cavity during use.Described lid can be twisted to lock it, and prevents the accidental activation of locking apparatus thus.

As selection, locking device can be the form of obstruction, described obstruction is formed on one (for example top or the base portions) of main body hinge bar or parts, and can be pulled to be formed on relative hinge bar or parts on shaped portion carry out closely against joint, and form the obstruction of outlet thus, this obstruction only just can be removed removing obstruction before use by the operator.In a specific preferred embodiment, obstruction is formed on the main body top, and is configured to and can optionally be bonded in the outlet opening that is formed in the base portion, and blocks this outlet opening.Therefore, the operator can shift obstruction onto in the outlet opening with the locking outlet, and can before use obstruction be pulled out and break away from and the engaging of outlet opening, and this can engage accompanying drawing below and be described further.

Air release/leak valve

Described device can also comprise a steam leak-off valve, and air can flow with any pressure differential between the inside and outside environment of equalizing reservoir by this steam leak-off valve.In some cases, gas leaks just and takes place by the fit-up gap between dispenser nozzle and the container, but this is not preferred, may leak because if container just is squeezed or is shaken.But in a preferred embodiment, dispenser nozzle also comprises a steam leak-off valve, if promptly be suitable for permitting air to flow in the chamber container is squeezed the check valve that can prevent that any fluid from leaking from container.Any suitable one-way valve system is all satisfied the demand.But preferably, steam leak-off valve is integrally formed in the main body of distributor, perhaps more particularly, is formed between two members of main distributor.

More preferably, steam leak-off valve is formed between the top and base portion that limits the dispenser nozzle chamber.

Preferably, steam leak-off valve comprises a valve member, and this valve member is disposed in by apparatus main body and limits and fluid source is connected internally in the chamber of external environment condition.More preferably, valve member is flexibly biased, so that contact chamber sidepiece, and with its formation sealed engagement, to prevent that any liquid from leaking out from container, described valve member also is suitable for strain or displacement breaks away from and the sealed engagement of chamber sidepiece, to limit an opening, when container inner pressure drops to when being lower than at least one minimum threshold of external pressure, air can flow into container by described opening.In case the inside and outside pressure differential of container reduces to when being lower than minimum threshold pressure, valve member is just got back to the pent position of chamber.

Preferably, valve member is the form of the piston that extends into chamber, and comprises an outward extending wall, and described wall adjacent chamber sidepiece is to form sealing.Preferably, outward extending wall also forms certain angle towards internal tank.This structure means and is applied on the valve member wall and the high pressure in container can cause that wall keeps and abutment.Therefore, sealing integrity can be held, thereby prevents that liquid from spilling by valve.On the contrary, during minimum threshold at least below container inner pressure is reduced to external pressure, described wall deflection breaks away from container side, allows air to flow into container, with balance or reduce pressure differential.

Particularly preferably be, piston is installed on a deformable base or the lobe, when dome is pressed so that may be accumulated in any residue displacement in the steam leak-off valve time, described base portion or lobe can carry out some and move.In addition, preferably, can in steam leak-off valve, provide a kind of removable (for example elastically deformable) element, because this helps preventing that in use valve gets clogged.

In some embodiments of the invention, also preferably, on the negative tube opening on the device inner surface, provide over cap, to contact with valve member under the situation that prevents the high or excessive power of liquid when container is squeezed or rocked strongly that internal tank exists.Described lid can allow air and some fluids to flow through, but can prevent the hermetic unit that the fluid influence is directly formed by the piston flared end, and can prevent that sealing from partly suffering the influence of excessive force.

In a selectivity embodiment, the groove of steam leak-off valve can strain rather than male portion branch generation strain.This structure can be configured so that the trenched side-wall distortion is to allow air to flow into container.

Valve member can be made by identical materials or different materials with groove.For example, they can all be made by half flexiplast, and perhaps female element is made by a kind of rigidity plastics, and positive part is made by the material of elastically deformable.

Along with the past of time, some products that are stored in the container have a problem relevant with gas, and gas is along with the time accumulates in the bottle in the past.Build-up of pressure is inevitably, in order to discharge the pressure of this gathering, needs a relief valve.By providing one or more strias at the groove sidepiece, above-mentioned steam leak-off valve can be modified and additionally carry out this function.Contact the hermetic unit that forms by passing by valve member with the groove sidepiece, these grooves can allow gas slowly to ooze out container, but can prevent or volume that minimum liquid is oozed out.Preferably, this groove or these grooves that are formed in the trenched side-wall are formed on the outside of the contact point between valve member and the groove sidepiece so that it or they only increase and act on the piston and cause that piston outwards just is exposed during (with respect to container) distortion at container inner pressure.Described piston can be got back to its fexible bias pressure position, and in this fexible bias pressure position, in case any excessive power is issued, these grooves just are not exposed.In this process, there is not fluid product to be lost.

As selection, the gas pressure in the container can be with valve member to extrapolation, so that it is from the groove displacement and limit the opening that a gas can flow through.

Sealing device

In comprising the preferred embodiment of the present invention of at least two members, preferably, sealing device is disposed on the abutment between two interconnecting components at least, spills from dispenser nozzle to prevent any fluid.Any appropriate sealing means all meets the demands.For example, two parts can be soldered to each other and go up, perhaps a part is configured to sting be coupled to another part and carries out sealed engagement, perhaps has a flange at its periphery, and this flange can closely be assemblied in the upper surface of another part on every side to seal with its formation.

Preferably, this sealing device comprises a positive protuberance that is formed at least two parts on one the abutment surface, when described positive protuberance is joined together at two parts, with the relative abutment surface that is formed on another part on the corresponding groove form of carrying out sealed engagement admitted.

Preferably, this sealing device extends around whole chamber and outlet, oozes out so that the fluid that spills from any position of distributor can be prevented between two abutments between the member.

In comprising some embodiment of exit passageway, projecting part can extend through passage, and forms the strain valve member of outlet valve.This part of protuberance is thinner usually, so that necessary elasticity to be provided in valve member, thereby allows it to carry out its effect.

In some embodiments of the invention, positive protuberance can be configured to sting and be coupled in the groove, and perhaps as selecting, positive protuberance can be configured to resistance is arranged be assembled in the groove to be assembled to similar fashion in the receiver hole with obstruction.

Dip-tube

In most of the cases, dip-tube can form with distributor is whole, and perhaps as selection, main distributor can comprise a groove, and independent dip-tube can be assembled in this groove.During use, dip-tube can be drawn fluid from the container deep inside, and dip-tube all exists in fact in all cases.

As selection, at some containers some small volume containers for example in balsam bottle, scent flask and the spray nose device particularly, it is desirable to omit dip-tube, because during use, install and self can extend into container so that product is introduced distributor, perhaps container can be squeezed to help the distributor perfusion of fluid.As selection, device can also comprise a kind of fluid compartment, and described fluid compartment forms as integral part of device, and fluid can directly be introduced fluid in the nozzle entrance from this compartment under the situation that does not need dip-tube.

Internal chamber

The chamber of spray nozzle device can be any form, and what will recognize certainly is that the size and dimension of dome will be selected to the specific device and the application that can be fit to be correlated with.Similarly, when dome was extruded, according to relevant applicable cases, all fluids in the chamber can be discharged from, and perhaps, as selection, have only the part of the fluid that exists in the chamber to be assigned with.

In some preferred embodiments of the invention, chamber be by one of main body generally the dome-shaped resiliently deformable territory limit.Preferably, dome shaped region is formed on the upper surface of main body, so that can allow the operator near pressing it.A problem of cheese chamber may be, when the chamber person of being operated pushed, the blind area of some can be present in the chamber, and for certain situation, preferably, the blind area is minimized or in fact can be left in the basket.In order to obtain this attribute, it is found that the chamber of flattened dome or other shape generally also is preferred, the condition of the chamber of other shape is, the strain wall of chamber can be depressed, so that it contacts the relative wall of chamber and discharges all the elements thing that wherein exists thus.Therefore, flattened dome is particularly preferred, the pressing cavity and cause the extruding degree that fluid wherein is assigned with that is stored in because it has reduced that dome need inwardly be pressed.It has also reduced the needed extrusion number of times of preparation chamber when using first.

In some cases, the strain of main body part can not be sufficiently flexible, so that it keeps its initial elasticity voltage biasing structure after distortion.This can be following this situation, and fluid has high viscosity, therefore tends to resist by inlet be drawn in the chamber.In this case, can provide extra elasticity by the pillar that one or more elastically deformables are set in chamber, when chamber was extruded, described pillar can be crooked, when applied pressure was removed, described pillar back into its initial elasticity voltage biasing structure with the crushed element of main body.As selection, one or more thick ribs of plastic can be extended in the middle of this part from the edge in strain zone.Be applied to the strain part of main body when pressure, these ribs play the effect of sheet spring effectively, and when applied pressure was removed, these ribs back into its initial elasticity voltage biasing structure with this part, in this way, these ribs increase the elasticity in strain zone.

Another selection is that the elastic device of spring or other form is disposed in the chamber.As mentioned above, when wall was out of shape, spring can push, when applied pressure is removed, spring can back into the crushed element of main body its initial elasticity voltage biasing structure, and in the process that pushes back, also impels the chamber that is extruded to get back to its initial " non-extrusion structure ".

Two or more chambers

Spray nozzle device of the present invention can comprise the internal chamber that two or more are independent.

Each chamber can by independent inlet never the independent fluid in for example same container of homogeneous turbulence body source fill in the compartment fluid guided in the spray nozzle device.

As selection, one or more other chambers can not comprise inlet.On the contrary, the memory of one other fluid can be stored in the chamber self, and other chamber or its outlet scheduled volume that can be configured to only to allow one other fluid is assigned with according to separately actuation motion.

Select as another kind, one or more chambers of other chamber can be introduced air from spray nozzle device is outside.No matter an other chamber or a plurality of chamber comprises air, still comprise some other fluids that attract in the compartment that separates from container, the content of two or more chambers can be by pressing together two chambers simultaneously, and be discharged from by outlet simultaneously.The content of each chamber is mixed in outlet then, and is perhaps when discharging from spray nozzle device, after discharging or before discharging, mixed.What recognize is if change the relative volume of separate chambers and/or the size of outlet, can influence the relative scale of the composition that exists in the final mixture of discharging by outlet.In addition, exit passageway can be divided into two or more grooves that separates, and each groove extends from separate chambers, and each separating groove can supply fluid in the aforesaid nozzle passage, before discharging fluid, fluid is just mixed in described passage.

If exist an additional chamber to be used to discharge air, will recognize that so a denier air discharge process is finished, and applied pressure is removed and allows chamber distortion to get back to its initial expanded configuration thus, so, more air need be introduced into chamber to replenish the part that is discharged from.This can realize in the following manner, promptly by outlet air is sucked back (that is, not providing this to have the further chambers of air-tightness outlet valve), perhaps, more preferably, by the inlet in the main body that limits chamber air is sucked.Under a back situation, inlet preferably is provided with one and the similar check valve of above-mentioned inlet valve.This valve only can allow air to be introduced in the chamber, and prevents that when chamber is extruded air is discharged from by the hole.

In most of the cases, it is desirable to, under approximately identical pressure, discharge air and fluid from container together.This will require air chamber to push than fluid/liquid accommodating chamber many (for example many 3-200 doubly depend on relevant applicable cases).This can realize in the following manner that promptly by chamber is positioned to, when exerting pressure, the extruding meeting of air accommodating chamber preferentially takes place, and air is discharged under identical or substantially the same pressure with liquid.For example, the air accommodating chamber can be positioned in liquid containing chamber back, so that when exerting pressure, air chamber at first is compressed, up to reaching two compressed together stages of chamber.

As selection, spray nozzle device also can be modified by this way, promptly will make air pressure can be higher or lower than fluid pressure, and this may be favourable to some applicable cases.

These chambers can be arranged side by side, and perhaps a chamber is positioned on the top of another chamber.Hold in the preferred embodiment of air a further chambers, the chamber of the relative spray nozzle device of additive air chamber is provided with, and partly is out of shape the described chamber with the extruding jet nozzle device so that the extruding of air chamber can cause the main body strain.

Preferably, the fluid that exists in each chamber is discharged from simultaneously.But what will recognize is that under some applicable cases, a chamber can be discharged its fluid before or after another chamber.

In selectivity embodiment, the air and the fluid that come from container may reside in the single chamber, rather than are present in the different chambers.In these cases, fluid and air are discharged from jointly, and can mix when it flows through outlet.For example, if outlet comprises an expansion chamber, i.e. expansion chamber that is arranged in exit passageway, so, the content that is discharged from from chamber can be divided into different groove branches, and enters expansion chamber at diverse location, mixes promoting.

The specific embodiment

In the description to accompanying drawing, identical Reference numeral is used to represent identical or corresponding part in the appropriate location of different accompanying drawings hereinafter.

The embodiment of the dispenser nozzle shown in Fig. 1 comprises a main body 400 that is formed by two parts, and these two parts are a base portion 401 and the top/rigid top 402 that is installed to the upper surface of base portion 401.This main body 400 is made by rigidity plastics.

The downside of base portion 401 comprises a thread groove, makes described main body can be fixed to the thread neck part of container, thereby forms threaded cap effectively.As shown in Figure 1, top 402 is installed to the upper surface of base portion 401, and is dome-type projection basically in one of the upper surface formation of main body 400.This doming is the elastically deformable part of main body, and the operator can push this part so that it is to internal strain, to reduce the volume of internal chamber.This makes fluid spray by outlet opening 403 in the chamber.

The perspective view of base portion shown in Fig. 2 401.With reference to figure 2, base portion 401 comprises the part 501 of downward extension, and the lower surface of this part is provided with above-mentioned thread groove.The upper surface of base portion 401 has the perimeter edge 504 around indented central part 502.This recessed portion 502 comprise shape basically as the dome of putting upside down divide 502a than the deep, describedly divide to extend to form the bottom of the outlet that is spout-like generally than the deep, this outlet has the edge 505 of a part that limits oral pore.In the zone of the outlet edge 505 of base portion 401, recessed portion 502 forms abutment surface 502b, and this surface limits the exit passageway/valve of dispenser nozzle with top 402, and this passage/valve leads to the outlet opening that the respective edges by edge 505 and top forms.

Groove 506 is positioned at

groove

502, and 504 the inboard at the edge just in time, and the importance to this groove in the discussion of Fig. 3 will become clearly hereinafter.Inlet opening 503 also is positioned at the regional 502a of groove 502, and in use, fluid can be introduced dispenser nozzle by this inlet opening from the container that links.The opening of inlet 503 is positioned at another groove 503a, hereinafter its importance in the discussion of Fig. 3 be will again become apparent.

Illustrate in greater detail the lower surface (for illustrative purposes, having put upside down the top shown in Fig. 3) on top 402 among Fig. 3.Lip 601 is around the lower surface on top 402, when top 402 is installed on the base portion 401, this lip is contained in the groove 506, forming tight seal between base portion and top, thereby prevents that joint between base portion 401 and top 402 from any fluid taking place leak.The lower surface on top extends between lip 601, and presents a structure that is essentially dome-shaped groove at the 602a place, and when base portion and top linked together, described groove was aimed at recessed portion 502a; And described groove extends to form an abutment surface at regional 602b, and this neighbouring surface contacts with the relative adjacent surface 502b of base portion 401 in the dispenser nozzle that assembles, to limit exit passageway.This top also comprises flap projection 603, and when upper surface was installed to base portion 401, this flap boss fell within the groove 503a, and flexibly is pressed against on the inlet opening 503.This flap projection 603 forms the valve member of the elastically deformable of inlet valve.

By with reference to the viewgraph of cross-section shown in figure 4A and the 4B, can understand the internal structure and the operation of the dispenser nozzle 400 shown in Fig. 1 better.With reference to figure 4A, the lower surface of base portion 401 comprises groove 701 and 702.Groove 701 comprises a screw thread (not shown), and profile is circular, thereby can be installed to the round thread neck opening of a container.On the other hand, groove 702 can be used for holding a dip-tube 704, and extends to form the inlet opening 503 of dispenser valve.The part 502a of the upper surface 502 of base portion 401 limits internal chamber 700 with the part 602a of the lower surface on top 402.The part 502b of upper surface limits an exit passageway with the part 602b of the lower surface on top 402, and this passage leads to the outlet opening 403 that the edge 605 by the edge 505 of base portion and top limits.Therefore, the part 602a on top 402 is made by the thin slice of the rigidity plastics that can bear strain.Therefore, this part of main body 400 is the elastically deformable part that limits the main body of described chamber.The adjacent surface that is formed by the part 602b on top 402 is deformed to the position that this passage is opened with also being configured to the fexible bias pressure structural elasticity that can close from the exit passageway shown in Fig. 4 A and 4B.Thereby the exit passageway of this elastically deformable forms the outlet valve of this device effectively.In addition, as mentioned above, the flap projection 603 on top is contained in the groove 503a of the inlet 505 of described chamber, to form an inlet flap valve.

In addition, in use, exert pressure, can make the elastically deformable part distortion downwards on the top 402 among the regional 602a by for example operator's finger area pressed 602a.The use of pressure makes the volume in chamber 700 reduce, and pressure wherein increases.When the pressure in this chamber surpasses predetermined minimum threshold, can make the opposite face 502b of the adjacent surface 602b distortion on top away from base portion, to form an exit passageway of opening, the fluid in the chamber can pass through this passage, and is ejected by the outlet 403 of dispenser nozzle.Can recognize that lobe 603 can prevent that fluid from passing through inlet and flowing out described chamber.When fluid is discharged, because the fluid that exists in the chamber is assigned with,, and drop to when being lower than minimum threshold when pressure so the pressure in the chamber 700 can reduce gradually, the adjacent surface of the elastically deformable of exit passageway 602b is got back to the position of abutment surface 502b with distortion, and exit passageway is closed.

If remove the pressure that is applied on the described chamber subsequently in regional 602a, so, because this chamber is got back to expansion structure by means of its intrinsic strain, the pressure in the described chamber can reduce.Because enter the mouth 503 and chamber 700 between pressure differential make 603 deflections of flap projection away from the ingate, so this pressure reduce can make fluid be drawn into described chamber by inlet.In case the part 602a on the top of main body presents its initial elasticity voltage biasing structure, flap projection 603 just deforms back to position shown in Fig. 4 A, thereby inlet is closed.

As selection, the main body of Fig. 1 to 4 illustrated embodiment can be made by pliable and tough elastomeric material.Distributor can be by any suitable molding process manufacturing.For example, base portion 401 and top 402 can be separately molded, link together in identical or the mould that separates then; Perhaps as selecting, can earlier molded parts, another parts can be molded on these first parts.

Another embodiment of the present invention shown in Fig. 5 A and the 5B.Among this embodiment and Fig. 1 to 4 by the embodiment shown in the identical Reference numeral much at one.The only difference of embodiment shown in this embodiment and Fig. 1 to 4 is, shown in Fig. 5 A, its top 402 is connected to base portion 401 by hinge or collapsible joint 801, this hinge or joint make top 402 can fold into base portion 401 and engage, to form the dispenser nozzle that assembles shown in Fig. 5 B.In this embodiment, top forms by rigidity plastics is whole, but in another embodiment, this top can comprise the framework of a rigidity plastics (identical with the plastics of base portion), and flexiplast is molded on this framework.

The major advantage of Fig. 5 A and 5B illustrated embodiment is that base portion 401 and top 402 are integrally formed, this means, the integral body of distributor can be by single kind material molded forming in single step, therefore its whole advantages are exactly, because have minimum assembling and process time, so reduced cost.For example, distributor can carry out molded with the Unclosing structure shown in the accompanying drawing 5A, and is then that top is folding around Connection Element 801, thereby forms the spray nozzle device that assembles.

Accompanying drawing 6A has shown an alternative embodiment of the invention, this embodiment is identical with the embodiment shown in the accompanying drawing 5A, just this embodiment also comprises a steam leak-off valve, described steam leak-off valve is fit to allow gas from outer side inflow container, with any pressure differential that may exist between equalizing reservoir and the external environment condition (but for example, when if container is squeezed, can prevent another direction of direction of flow).

Shown in Fig. 6 B, described steam leak-off valve is made up of a strain valve member 1101, and when dispenser nozzle was assembled, described strain valve member was accommodated in the opening 1102 of base portion.Opening 1102 forms a passage with described groove 1103, and air can be by the outer side inflow container of this passage from the dispenser nozzle that assembles.Elastic deformation component 1101 top is provided with a flared rim, the inwall of its edges abut opening 1102, thus form aeroseal.If the pressure in the container is reduced because discharge fluid by dispenser nozzle, so the pressure differential between internal tank and the external environment condition cause element 1101 flared rim to internal strain, allow air to flow into the container thus from external environment condition.Shown in Fig. 6 B, in case pressure differential is balanced, flared rim is just got back to its initial elasticity voltage biasing structure so.What will recognize in addition is, if container is squeezed, product can not leak by the rim by elastic deformation component 1101, and for example by squeeze receptacle, and the wall that any pressure that is applied can be shifted flared rim onto simply with opening 1102 carries out adjacency more closely.
