Perhaps, two parts can be made by rigidity or flexible material, although under latter event, the first of described main body must remain rigidity basically.The material of any suitable this spray nozzle device of manufacturing of rigidity and flexible material.For example, it can be by making such as the metal material of aluminium foil or such as the flexible material of rubber.But preferably this device main body is made by rigidity plastics fully, although flexiplast can be used for provider's first if necessary.
Best, the first of main body is made by rigidity plastics.Best, entire pump action spray nozzle device (that is, main body and actuator) is to be made by a kind of rigidity plastics.
Terminology used here " rigidity plastics " refers to the plastics that have high rigidity and intensity after being molded as required form, but also can make it have certain flexible or part strain by the thickness that reduces plastics.Like this, can provide thin parts of plastics to limit at least a portion of the main body of described chamber and elastically deformable with formation.
Terminology used here " flexiplast " expression to be flexible inherently/strain help the plastics of the compression in described chamber with the elastic displacement of at least a portion that can make main body.The flexible scope of plastics can be depending on plastics at any given zone or the thickness in the part.For example, such " flexiplast " is used for the preparation of Air shampoo bottle or shower gel container.In the manufacturing of spray nozzle device of the present invention, the part of main body can be made by the thicker part of plastics and think that this structure provides required rigidity, and other parts can be made of so that required morphotropism to be provided the thin part of plastics.Needing in some zone if necessary, can provide the framework than thickness portion under the situation of extra rigidity, is commonly called brace rod.
Utilize a kind of material to form this device and can make the entire body of this spray nozzle device in molded operation of a mould neutralization, be molded, as described further below.
Utilize a kind of material to form this spray nozzle device, special two parts therein are integrally molded and are interconnected so that top can be swung in the preferred embodiment of contact base portion with the spray nozzle device that forms this assembling by folding Connection Element or articulated joint, need not the assembling of a plurality of independently parts.In addition, utilizing a kind of material to form this spray nozzle device provides possibility that two parts are welded together (for example, by heating or ultrasonic bonding) or, if plastics are a kind of rigidity plastics, can between top and base portion, form a kind of snap fit so and connect.A kind of selection in back can also make top periodically separate so that clean with base portion.
Use for great majority, spray nozzle device need be made by a kind of rigid material and think that actuator surface provides required intensity and can make two part snap fit or weld together.Under these circumstances, only when applying a certain minimum threshold pressure the deformable segment of described main body be tending towards being out of shape and this makes the pump action more be similar to the on/off action about conventional pumps action spray nozzle device.But in some applications, a kind of flexible material may be preferred.
But thin part of the second portion rigidity plastics of this main body that can strain, its strain is compressing this chamber when exerting pressure, and it is then got back to its initial elasticity bias voltage and constructs when institute's applied pressure is removed.
But in all cases, the abutment surface that preferably defines the exit passageway of outlet is formed by rigidity plastics.Although can use flexible/elastic deformation material for this reason, they are not preferred, and this is need critically be made by a kind of rigid material usually because have any injection variation characteristic on it.Like this, in some embodiments of the invention, can make by two kinds of materials for one in two parts in qualification outlet and chamber, promptly, a kind of rigid material that forms the abutment surface that limits exit passageway and outlet opening, and a kind of elastic deformation material who limits described chamber.
Outlet valve
In order to work in the best way, the outlet in chamber must be provided with or be suitable for use as check valve.This check valve makes the product that is stored in the chamber be assigned with by outlet in the time of can only reaching predetermined minimum threshold (owing to the strain wall reduces from the cavity volume that its initial elasticity bias voltage structure displacement causes) in described chamber, and closes outlet to form gas-tight seal in the every other time.Closing of valve prevents that air is being applied to that pressure on the strain part of main body discharges and the volume in chamber is got back to its initial elasticity bias voltage structure once more along with the strain wall and sucked back in the chamber by outlet when increasing when the pressure in the chamber is lower than predetermined minimum threshold.
Any suitable check valve assembly that can form gas-tight seal can be set in the outlet.But preferably this valve is that parts by the main body of spray nozzle device form.Best, this valve is formed between the abutment surface that limits exit passageway.
In certain embodiments of the present invention, outlet valve is to be formed by fexible bias pressure one of them abutment surface with the part of the length of cutting out exit passageway on relative abutment surface.In this, thus during the open channel that the fluid in the pressure in the chamber is enough to make the fexible bias pressure abutment surface to form away from relative abutment surface distortion can to make the chamber can flow through, described valve will only be opened so that fluid is assigned with from the chamber.After pressure drops to below the predetermined minimum threshold, the fexible bias pressure surface will be got back to its fexible bias pressure structure and close this passage.
In certain embodiments of the present invention, preferably the fexible bias pressure abutment surface forms with the strain of the main body that limits described chamber is partly whole.
Among the embodiment that described therein main body integral body is made by rigidity plastics, the resistance that will be provided by fexible bias pressure surface (will be the thin portion of rigidity plastics) may not fully recover to reach the required minimum pressure threshold of this device best effort.Under these circumstances, crossing the thickening plastics muscle that passage extends can be formed so that required intensity and resistance to be provided in exit passageway/valve.Perhaps, the rigidity reinforcement can be arranged on the top of section port passage/valve.
In a selectable preferred embodiment, outlet/precompression valve is to cross exit passageway and extend and to form with the elastic deformation component on one of them described abutment surface of closing and sealing this passage by being formed on.This element is installed on this device along an one edge and its another edge (being preferably opposed edges) is freely, free end travel when the pressure in the chamber surpasses predetermined minimum threshold.When pressure is lower than predetermined minimum threshold this free end against a surface of exit passageway with its formation sealing.But when pressure surpassed predetermined minimum threshold, the free end of this element can make and is present in the opening that fluid the described chamber can flow to outlet by it to form from the abutment surface displacement of passage.Best, this elastic deformation component is positioned at a chamber that forms along the length of exit passageway or path.Best, the abutment surface that forms sealing with the free end of this element when pressure is lower than minimum threshold is to reduce gradually or tilt at the free-ended contact point place with this element.This provides the dot encapsulation contact and more effective sealing is provided.Certainly, it should be understood that the gradient of abutment surface or tapering must be to arrange like this, that is, and elastic deformation component's free end contact gradient when the pressure in the chamber is lower than predetermined minimum threshold, but when surpassing predetermined minimum threshold, expand away from it.
Perhaps, this valve can be formed on one the abutment surface in base portion or the top and contact relative abutment surface to cut out pillar or the bolt with seal channel.This pillar or bolt make pillar or bolt deformable to limit the opening that fluid can flow through outlet by it in the time of will being installed on the deformable region on base portion or top and surpassing predetermined threshold with the pressure in the convenient chamber.
The predetermined minimum pressure that must reach in described chamber in order to open outlet valve will depend on related application.It will be understood by those skilled in the art that and how for example utilize the selection that is fit to the elastic deformation material or change the performance that the mode of making on described surface (for example strengthening spine by increasing) changes the strain surface.
Inlet valve
In order to move to the chamber and to guarantee that fluid only sprays by outlet when making that described chamber is compressed from its initial elasticity bias voltage structure, therefore check valve must or be set in spray nozzle device in the porch of spray nozzle device when the strain of main body part.
Can use any suitable inlet valve.
Inlet valve only can be suitable for the pressure in the chamber drop to predetermined minimum threshold when following (, the pressure on being applied to the strain part in chamber discharge and the volume in chamber get back to its initial elasticity bias voltage structure once more along with the strain wall and when increasing) open and make fluid flow in the described chamber.Under these circumstances, inlet valve is a kind of clack valve, and it is made of the flap of the elastically deformable that is positioned at the exit opening top.This flap preferably resiliently biased on the inlet opening and be suitable for pressure in the chamber drop to predetermined minimum threshold when following distortion so that fluid is pumped in the described chamber by inlet.But in the every other time, inlet will be closed, thereby prevent that fluid from flowing back into the inlet from described chamber.Best, the flap of strain is formed a whole extension of the strain part of the main body that limits described chamber.Best, the strain that base portion limits inlet and main body is partly formed by top.Therefore, best top is included in and extends in the described chamber with inlet opening that covers described chamber and the strain flap that forms inlet valve.
Perhaps, described flap not fexible bias pressure on the inlet opening but can be arranged on the inlet opening and only be compressed and wherein pressure is pressed on the inlet it when increasing in described chamber.
But, provide the flap of fexible bias pressure on the inlet opening may bring problem simply.Particularly, As time goes on, the elastic limit that forms the material of flap may be exceeded, thereby makes its cisco unity malfunction.This problem is the embodiment that is made by the thin portion of rigid material at flap among the present invention especially, but it also in very little scope at flexible material and when described chamber be compressed and when flap distortion when opening valve because the distortion of flap and this problem may occur.Therefore, fluid may drain back to the container by inlet from described chamber.
For this reason, preferably flap comprises a plurality of adapter structures.Particularly, preferably inlet has the outstanding antelabium that extends around the ingate, the strain flap against described outstanding antelabium around inlet, to form tightening seal.The providing of antelabium guarantee with flap between form good contacting.Therein among the embodiment that antelabium is very little, may provide one or more additional brace rod to form suitable seal and prevent that also antelabium is impaired guaranteeing in any side of inlet opening.
Another preferable feature is, flap has and is formed on its lip-deep projection or bolt.Described projection or bolt in the inlet opening, extend a bit of distance and against lateral edges with the formed sealing of further reinforcement.
Best, the inlet opening in described chamber be arranged on a rising in the described chamber the position so that fluid flow in the described chamber by inlet and drop into downwards hold or storage area in.This by the main fluid that makes inlet opening and described chamber effectively hold/thereby storage area maintenance certain distance prevents the possibility that fluid is in the top of inlet valve for a long time and reduces As time goes on to take place any leakage.
Best, second strengthens the apparent surface of flap or element contact resilient distortion flap to force it closely against the inlet opening.Best, second strengthen flap in the apparent surface of strain flap, covers the ingate the part place or near this apparent surface of contact so that the pressure at right angle of the main valve clack on this hole maximizes.In addition, this helps to keep the integrality that seals.
Locking
Spray nozzle device also can be provided with and be used to the locking device that prevents that the fluid accident is assigned with.
In such embodiments, this locking will be the integral part of main body and not be the individual components that links to each other with main body.For example, described locking device can swing to one with the whole hinge bar that connects of the part (for example, base portion or top) of main body or element and it and utilizes this bar or element can prevent the position that outlet valve is opened.
This locking device can comprise that also the strain part top that can be placed on main body is to prevent its compressed rigid cap.Described lid can link to each other with spray nozzle device so that it is folded by hinge.Perhaps, rigid cap is can be to lower slider in use to compress the slip loam cake in described chamber.This lid can be twisted to be locked, thereby prevents the accidental activation of this device.
Air release/leak valve
This device also can comprise can make air flow through air leakage device with any pressure differential between the inside and outside environment of equalizing reservoir.In some cases, air leaks and can only realize by the gap in the accessory between dispenser nozzle and container, but this is not preferred, and this is because if container is inverted or is rocked and may leak.In a preferred embodiment, dispenser nozzle also comprises the air leak valve,, is adapted such that air flows in the container that is, if but it can prevent that any fluid from leaking out from container when being squeezed.Any suitable one-way valve system may be utilized.But best described air leak valve is integrally formed in the main body of distributor or is preferably between two parts of main body of distributor.
Best, the air leak valve is formed between the top and base portion in the chamber that limits dispenser nozzle.
Best, the air leak valve comprise be arranged on limit by this device main body and make valve element in inside that fluid supplies with and the passage that external environment condition links to each other.Best, described valve element is resiliently biased with the side that contacts described passage and therewith form sealed engagement and leak out from container to prevent any fluid, and described valve element also is suitable for strain or from making air flow to opening the container by it with the sealed engagement displacement of passage side to limit when the pressure ratio external pressure in the container is hanged down minimum threshold at least.After pressure differential between container inside and outside had reduced and is lower than minimum threshold pressure, this valve element turned back to and can make the position of this pathway closure.
Best, described valve element adopts and extends to the form of the plunger in the passage and comprise the outward extending wall that seals with formation against the side of passage.Best, outward extending wall also forms certain angle towards the inside of container.This structure means that the high pressure that is positioned at internal tank and is applied on the wall of described valve element will make that wall keeps leaning with the side of passage.Therefore, thus kept the integrality of sealing to prevent that liquid from passing through described valve and leaking.On the contrary, when the pressure that is positioned at internal tank drops under the external pressure at least the minimum threshold amount, thereby described wall from the side deflection of described container to allow air to flow in the container balance or to reduce pressure reduction.
Best, described plunger is installed on deformable base or the sign, is pressed when dome portion so that can discharge when having accumulated in any remaining in the air leak valve, and described deformable substrate or sign can be mobile slightly.In addition, it is preferred that removable (for example, strain) element is provided in the air leak valve, and this is because it helps to prevent that valve is blocked during use.
In certain embodiments of the present invention; best, on the opening in female threaded pipe on the inner surface of device, provide the protection housing contacting with the valve element energetically or under the excessive force with the liquid that prevents from when container is reversed or shaken excessively, to be present in the internal tank.Described housing will allow air and some fluids to flow through, but will prevent that therefore fluid from directly impinging upon in the sealing that the horn-like end of plunger forms, prevent that sealing is subjected to excessive force.
In alternative embodiment, it is elastically deformable that the passage of air leak valve can replace male parts.Can so form this layout, that is, make the sidewall of described passage be out of shape to allow air to flow in the container.
Described valve element and described passage can be made with same material or different materials.For example, they can use half flexiplast to make or female element can be made with elastic deformable material by male parts with rigid plastics.
Exist and the relevant problem of gas that As time goes on accumulates in the bottle about the overtime product that is stored in the container.For the growth of release pressure (possibly can't avoid this thing happens), need relief valve.Above-described air leak valve can be modified to be convenient to also carry out this function by one or more fine grooves are provided in the side of passage.These fine grooves will allow gas slowly ground to spill from container, and the formed sealing that contacts from the side by valve element and described passage is walked around, but prevent that liquid from spilling or make the amount of liquid that can spill minimize.Best, be formed on the outside of contact point of side that fine groove in the described channel side wall is formed on valve element and described passage so that they only the pressure in container increase and act on the plunger so that it outwards just exposes during distortion (with respect to container).Described plunger will turn back to its fexible bias pressure position, and fine groove can not exposed yet when any excess air has been issued in described fexible bias pressure position.In this program, would not lose fluid product.

In Fig. 6, illustrate in greater detail the lower surface (for purposes of illustration, the top shown in Fig. 6 is reversed) on top 402.The lower surface on top 402 is centered on by lid 601, when top 402 is assemblied in base portion 401, described lid 601 is received in the passage 506 so that form gas-tight seal between base portion and top, thereby prevents that joint between base portion 401 and top 402 from any fluid occurring and leaking.The lower surface on top extends between the structure of the basic groove for domed shape of lid 601 and 602a place supposition, when base portion and top are joined together, the groove of domed shape aligns with slot part 502a is arranged, and extend to form abutment surface at regional 602b place, described abutment surface contacts to limit exit passageway with the relative abutment surface 502b of base portion 401 in the spray nozzle device of assembling.Top also comprises flap projection 603, and when upper surface was assemblied in base portion 401, flap projection 603 was arranged in groove 503a and resiliently biased with respect to inlet opening 503.Flap projection 603 forms the elastically deformable valve element of inlet valve.
To understand the internal structure and the operation of the spray nozzle device 400 shown in Fig. 4 better in conjunction with the cross-sectional view shown in Fig. 7 A and the 7B.With reference to Fig. 7 A, base portion 401 comprises groove 701 and 702 on its lower surface.Groove 701 comprises that screw thread (not shown) and its profile are circular so that it can be assemblied in the round thread neck opening of container.On the other hand, groove 702 is suitable for receiving dip-tube 704 and extends so that form the inlet opening 503 of dispenser valve.The part 502 of the upper surface 502 of base portion 401 limits inner chamber 700 with the part 602a of top 402 surface underneath.The part 502b of upper surface defines exit passageway with the part 602b of top 402 lower surfaces, and described exit passageway leads to the edge 505 of base portion and the outlet opening 403 of edge 605 qualifications on top.Therefore, the part 602a on top 402 makes with the thin part of the rigidity plastics that can stand strain.Therefore this part of main body 400 is the elastically deformable part that defines the main body of chamber.The formed abutment surface of the part 602b on top 402 also is configured so that can be from the pent fexible bias pressure of the exit passageway structure position that is opened for path wherein of strain down, as shown in Figure 7A and 7B.Therefore, the strain exit passageway forms the outlet valve of described device effectively.And the flap projection 603 on top is received in the groove 503a of the inlet 505 of chamber to be formed into the oral lobe valve, as previously described.
Therefore, during use, in regional 602a, the elastically deformable on top 402 part can be by for example pushing to exert pressure in this zone and distortion downwards by operator's finger.The applying of pressure makes the volume of chamber 700 reduce and pressure wherein increased.When the pressure in the chamber has surpassed predetermined minimum threshold, to cause the abutment surface 602b on top to be out of shape away from the apparent surface 502b of base portion, be present in that fluid in the chamber can pass described exit passageway and the outlet 403 by spray nozzle device is discharged from so that limit the opening exit passageway.It should be understood that by flap 603 and prevent that fluid from passing through inlet and flowing out chamber.When fluid is injected, along with the fluid that is present in the chamber is assigned with, pressure in the chamber 700 will reduce gradually, and the elastically deformable abutment surface of exit passageway 602b is got back to its abutment surface 502b with distortion under it drops to minimum threshold time the position and exit passageway are closed.
If when putting on pressure on the chamber among the regional 602a and being removed, along with chamber returns expanded configuration by means of its intrinsic strain, the pressure in the chamber will reduce.Because the pressure differential between inlet 503 and the chamber 700 makes that flap projection 603 deflections must be away from the ingate, thus this pressure reduce make fluid be inhaled in the chamber by inlet.In case the part 602a on the top of main body presents its initial elasticity bias voltage structure, flap projection 603 just is out of shape go back to the position shown in Fig. 4 A, thereby inlet is closed.
As an alternative, the main body of the embodiment shown in Fig. 4 to 7 can be made with flexible plastic material.Distributor can be made by any suitable molding program.For example, base portion 401 and top 402 can by independent molded after in same mould or independently in the mould they are being linked together, perhaps, at first parts of molding then are molded in another parts on first parts.
The example that is suitable for the spray nozzle device of the form distributing fluids of a group liquid (rather than spraying) has been shown among Fig. 8 A and the 8B.Remove this embodiment and comprise that also the container that is suitable for allowing air to flow into from the outside and may exists with balance the container and any pressure differential between the external environment condition (but prevent other path of direction of flow, if for example container is reversed) the air leak valve and top is integral with each other with base portion and the fact that is connected by collapsible Connection Element 801 outside, in fact Fig. 8 A is identical with the example shown in Fig. 4 to 7 with the embodiment shown in the 8B.
In this embodiment, top forms by rigid plastic material is whole, and still, in alternative embodiment, top can comprise the framework of rigidity plastics (identical with the material of base portion), and flexible plastic material by overmolded thereon.
The major advantage of embodiment shown in Fig. 8 A and the 8B is, base portion 401 and top 402 are formed by whole, the entire body that this means distributor can be molded with a kind of material in a step, owing to minimize assembling and processing time, therefore also is attended by the advantage that reduces cost.For example, as shown in Fig. 8 A, distributor can be molded in the hatch frame, and top can be folded on the Connection Element 801 to form the spray nozzle device of assembling.
Figure 9 illustrates another example that is suitable for the spray nozzle device of the form distributing fluids of a group liquid (rather than spraying).Distributor shown in Fig. 9 comprises the many features in the previous embodiment, and is shown as similar Reference numeral.Yet, also have some improvement.
Particularly, the outlet 403 of device 1401 has been modified to make that product is distributed along the direction of arrow 1405 downwards.Certainly it should be understood that outlet can be configured so that in arbitrarily angled allocated product (for example, becoming 30-45 ° with respect to vertical direction) down.
Exit passageway also is suitable for comprising locking device.Described locking device comprises the stopper 1406 that is formed on the top 402.Described stopper extends so that form button 1407 on the upper surface on top 402, and described button can be pressed so that stopper 1406 is pushed to and outlet opening 703 sealed engagement mutually, as shown in Figure 7.Under this structure, stopper 1406 seals outlet 703 and prevent that fluid is assigned with from chamber.For depressurization and allow fluid to be assigned with by exporting 703, the operator must upwards spur button 1407 so that stopper 1406 is removed from outlet.After removing, the part 602b elastically deformable on top must be away from the abutment surface of base portion 502b so that when chamber is compressed qualification opening exit passageway.When this strain of fluid part 602b on top when outlet 703 is flowed also removes stopper so that limit the path that fluid can flow through from exporting near 703.As long as the content in the chamber is assigned with, the part 602b on top and stopper 1406 are just got back to distortion the position of sealing exit passageway.In this, stopper 1406 is positioned in the outlet 703 forming check-valves effectively, and described check-valves prevents that any air or product are sucked back in chamber.After using, the operator can push button 1407 to stop up outlet and to avoid the anything unexpected of device to operate.
The element that is generally L shaped shape 1408 with lid 1408a hangs down and outstanding by outlet 703 from the base portion of stopper 1406.When stopper was in outlet 703 sealed engagement, as shown in Figure 7, lid 1408a was from the downside displacement of base portion.Yet when button 1407 is pulled when removing stopper 1407, the lid 1408a of element 1408 is against the downside of base portion and prevent that button 1407 is pulled too far.Can use any other device that prevents that button 1407 is pulled too far.
The ridge 601 formed sealings that are received in the corresponding track 506 are modified aspect two.At first, described sealing is extended around the whole circumference of chamber 700, in addition, and around the exit passageway between the abutment surface of the 602b on part 502b that is limited to base portion and top.Therefore, formed complete sealing in case the fluid stopping body leaks between top 402 and the base portion 401 and from nozzle spills.The second, the thickness of ridge projections correspondingly reduces towards its opening towards the width of its base portion inclination and track 506.Therefore, ridge 601 can be pushed or be snap-fitted in the track 506 and engage to form tight seal, and this can be used for top 402 and base portion 401 are fixed together.
The flap valve element 603 of porch has been equipped with support arm 1420.Support arm 1420 is constituted for the flap 603 on the fexible bias pressure ingate, enters the mouth 503 thereby increase the intensity of formed sealing between them and make flap 603 be out of shape required pressure and open during use.
Pump dispenser shown in Fig. 1 to 9 comprises on upper surface and is generally dome-type projection, and described dome-type projection must be by operator presses with compression chamber and make the content that is stored in wherein be discharged from by outlet.The potential problems that described design is followed are, the operator need be with their finger presses dome, and this requires the operator that their finger is placed on the tram to be compressed fully to guarantee described chamber.What found is, need elevated pressures dome is pressed into enough degree, this may be another defective, especially when for people, handling conventional pump and become universal phenomenon by exerting pressure with the different piece of hand (for example, when the palm that uses them or even utilize their ancon or forearm).In these cases, for handle fluid from the device injection and with palm push dome to enough degree will be very the difficulty.
Therefore, proposed of the present invention another and improved embodiment, this embodiment can be handled with their hand or any position of arm by the operator, and in 10c this embodiment has been shown at Figure 10 a.Figure 10 a shows unassembled embodiment of the present invention, and wherein base portion 401 and top 402 are separated from each other.Base portion 401 is connected by flexible/collapsible Connection Element 2002 with top 402.Figure 10 a makes with rigid plastic material to the embodiment shown in the 10c, although also available flexible plastic material is made.Whole spray nozzle device is formed independent building block, and this building block is to form and take out from the mould of the structure shown in Figure 10 a by treatment step is molded.As previously described, upper surface can be swung and be assemblied in top 402 to form the nozzle arrangements of assembling, as shown in Figure 10 b on the upper surface of base portion 401.
With reference to Figure 10 b, what can find out is, in assembling structure, the projection 1210 of extending around the upper surface circumference of base portion 401 is received in and is formed on track 1211 sealed engagement in the top 402 so that forms and be tightly connected between base portion 401 and top 402, and the flap 603 of elastically deformable is received in the groove that is formed in 503 the base portion of entering the mouth with the formation inlet valve.The front has been described this two kinds of structures.Yet opposite with previously described embodiment, top 402 also has two elements 2501, and described element 2501 comprises the indenture 2501a that is suitable for receiving the tip that is formed on two pivot projections 2502 on base portion 401 upper surfaces.This layout can make top 402 pivot with respect to base portion so that the part 602a on top can be towards the part 502a displacement of the upper surface of base portion 401 with compression chamber 700, as shown in Figure 10 c.
First/actuator surface the 602a of apparatus main body is formed at top.The second elastically deformable part by elastically deformable sidewall 2504 provider's devices of base portion.Wall 2504 is resiliently biased presenting the structure shown in Figure 10 b, thereby makes actuator surface 602a present its maximum volume from base portion displacement and chamber 700.
When along the direction of arrow 2505 when actuator surface 602a exerts pressure, 2504 distortion of elastically deformable sidewall so that actuator surface towards the part 502a of the upper surface of base portion displacement, thereby compression chamber.The pressure that increases in the chamber makes stopper 1406 be assigned with from chamber from exporting 403 displacements and fluid.Can use any suitable outlet valve described in the literary composition to replace stopper 1406.When institute's applied pressure was disengaged, wall 2504 turned back to its initial elasticity voltage biasing structure, as shown in Figure 10 b, thereby increased the volume of chamber, reduced pressure wherein, and made more the multithread body 503 be inhaled in the chamber by entering the mouth.
Stopper 1406 is effectively as precompression valve, and described precompression valve guarantees that fluid only is assigned with when wherein pressure is enough to make stopper 1406 from the outlet opening displacement from chamber 700.In order to make fluid pass stopper 1406, stopper 1406 preferably hollow so that its deformable is to limit passage, perhaps, must have enough spaces above the stopper so that it is removable under the situation of its distortion.
In addition, this device selectively comprises with top 402 is whole and forms and can swing and against the locking member 2510 of base portion 401 (as shown in Figure 10 b), can pivot and compress described chamber 700 to prevent top 402.Therefore, the locked and unexpected actuating of this device will be prevented from.Locking member 2510 can be thrown off can make this device be operated in the above described manner with base portion 401.
Main difference between this embodiment and foregoing embodiment is that the actuator surface 602a on top 402 is rigidity and indeformable when exerting pressure basically.On the contrary, in wall 2504 strain appears.This provides such advantage, that is, operator's actuator surface provides the sliding-contact point for the operator.In addition, the operator can use any part of hand or arm to carry out the distribution of fluid from container.This structure also provides and has improved mechanical efficiency.
Another difference is to make the very high percentage of main body partly move when exerting pressure.
