Background technology

Eduction gear is known, particularly at cosmetics and medicine field.It allows user's discharge medium that aims at the mark, for example, and to dermal administration skin cream, or in nose or otherwise administration.

A large amount of known eduction gears are made into discharge process can be by pumping plant by repeatedly activating and repeat.A kind of eduction gear design of specific type is different, and it is for by once activating or discharging medium by twice actuating from medium receiver.This eduction gear especially can be used for test, for example cosmetics test.In the situation that the eduction gear of nasal-cavity administration, it can be used for maybe can be by double actuating by the once actuating of eduction gear, emptying medium receiver.

Aspect infection, may need to use very in short time a large amount of medicinal eduction gears.For this reason, eduction gear commonly known in the art usually has quite unaccommodated structure, because it is too complicated, and can not produces in a large number at short notice and fill.In addition,, aspect these large quantities of administrations, conventionally also need to use eduction gear especially cheaply.

Therefore, one aspect of the present invention is the suitable eduction gear of simple especially structure, and its main composition is partly matrix and the deformable film that has rigidity, and they limit medium receiver jointly.

Summary of the invention

The present invention is intended to propose a kind of suitable eduction gear with having high duplication discharge characteristic of production prices that is combined with.

According to the present invention, the another tool following characteristics of general eduction gear.Eduction gear has matrix and deformable films, and medium receiver is set to the chamber in matrix, and chamber is at the upper side opening of matrix, and the chamber of this opening is sealed by deformable films.In addition, being provided with can be with respect to the actuating unit of matrix activity, and it has punch-out.Actuating unit is directed to by this way with respect to matrix: the movement by actuating unit with respect to matrix, decompressor can be bonded in above-mentioned chamber, preferably, fill to a great extent this medium receiver completely, thereby to the medium in medium receiver is expressed to discharge orifice.

Therefore, eduction gear of the present invention has three main composition parts.Matrix is the assembly that has rigidity, is preferably made of plastics, and is wherein provided with chamber.This matrix is at least preferably covered by the film of plastically deformable at some parts at upside, thereby at least complete the stage at eduction gear, it remains on the medium being arranged in the chamber of matrix in chamber.Preferably, the part of membrane sealed chamber opening side is flat along direction of extension at least substantially, thereby the edge with chamber adjacency of the upside of matrix is directly connected to each other.In the direction of extension of quadrature therewith, film needn't be flat forcibly.This gives supplemental instruction below.

In order to use the medium being stored in medium receiver after eduction gear is made, above-mentioned punch-out is set and enters chamber.By this method, the volume of medium receiver reduces, and medium is pressed into escape route towards the direction of discharge orifice.Here arranging can wide-spread film, so that unlikely, when inserting punch-out, break, until its end position, otherwise can leakage.Punch-out is arranged on actuating unit, and it can lead actively with respect to matrix, and preferably, it is for the timely application of force of user.Therefore, not the actuation part by user's free operant, actuation part must accurately locate to insert punch-out, but punch-out, it can be movable along motion path together with actuation part, thereby can immerse chamber, and without special technique.The medium squeezing out from medium receiver is pressed into escape route, guides discharge orifice into.

Preferably, escape route is mutually extensively restricted at least in part by matrix and film, as medium receiver.A breakpoint can be set by this method in escape route, and film is connected in matrix at this breakpoint, makes in escape route, to exist at first a breakpoint, and it separates medium receiver and discharge orifice.By the pressure in medium receiver between period of energization, increase, reach a pressure stage, its be enough to make in the region of this breakpoint film and matrix disconnected from each other, make medium enter discharge orifice, or another one breakpoint is opened.For this reason, and if then the previous application chamber of described breakpoint is arranged to the chamber in body portion, more favourable.Equally, this application chamber is limited by matrix and film, and the width of application chamber is much larger than its height, and by matrix, the distance apart from film limits for it.Preferably, width is at least 2 times of the height of application chamber, especially preferably at least 3 times.In the region of application chamber, film is not attached to matrix, therefore, the medium coming from medium receiver can flow into here without a doubt, and because film is because large width has sizable area, therefore can in the region of application chamber, provide larger power, it is enough to open breakpoint.

On the one hand, breakpoint is guaranteed to pollute and can not affect medium in the storage life.In addition,, due to the orientation of eduction gear, it guarantees that from then on medium can not miss.In addition, breakpoint can have pressure point function, because it needs very large authorized pressure in application chamber, to open breakpoint.During actuation part is mobile together with punch-out, set up the required power of this pressure, after breakpoint is opened, guarantee that medium discharges completely.As already mentioned above, body portion is preferably designed to a Plastic Parts, and itself is extremely hard.Especially can be designed to polyolefin assembly, especially polypropylene components or polyethylene components, average wall thickness is at least 0.5 millimeter.

On the other hand, film is substantially very thin, and its thickness mostly is 200 microns most, preferably, mostly is 100 microns most.Depending on the structure of film, thickness also can be less than 30 microns.Film can be designed to plastic film or metallic paper, especially aluminium foil.If film design is laminated film, preferably there is at least one plastic membranous layer and at least one metal foil layer.In this case, metal foil layer especially guarantees not have completely medium can ooze out medium receiver.By plastic membranous layer, especially to guarantee that necessity of film is flexible when punch-out enters to be guaranteed, it is required for preventing that medium from tearing Leakage in certain area at film.No matter use what material, in the situation that film has a plurality of thin layer, advantageously at least one thin layer has sufficiently high flexiblely, to allow punch-out to enter chamber completely, does not but tear this thin layer.Preferably, to be accurately designed to its breaking extension so low that to be enough to make it when punch-out enters chamber, to rupture as desired for the second thin layer.For this reason, preferably, there is larger ductile thin layer and there is at least 30% breaking extension, and there is less ductile film, there is maximum 25% breaking extension.Particularly, above-mentioned plastic layer can form the ground floor of two thin layers, and metal level especially aluminium lamination can form the second thin layer.These thin layers are designed to when punch-out enters, one of two films are at chamber Fracture, and cause pressure point effect, because film is divided into into until to have the tolerance intensity of less ductile thin layer fracture very large pressing part, and along with thin layer fracture and stand unexpected reduction.

Bonding technique can be used for making film to be bonded in matrix.But, preferably weld, for example heat-sealing or ultrasonic welding.This bonding in order to carry out, advantageously film is plastic film, or has at least one plastic film layers, and it is towards the direction of matrix, if for example acrylic plastering is for this thin layer and matrix for similar plastics, adhesive bonding property is good especially.

Because punch-out enters chamber, in the medium receiver being formed by chamber, the medium of contain can constantly repeatedly be discharged in advance.For this reason, preferably, the shape of punch-out and the mobility of actuating unit are suitable for the shape of chamber, make because the punch-out of movable guiding is inserted in chamber, and in medium receiver, at least 90% contents can squeeze out from medium receiver.For this reason, punch-out has substantially consistent shape with chamber.In addition, preferably, chamber design becomes to be essentially the dome of free edge, is understandable that, under described dome, in the chamber the inside as medium receiver, does not arrange and has the wall that radius of curvature is less than 2 millimeters.When by this method, punch-out enters owing to tilting or dead band unsettled and that may cause is avoided.

The volume of medium receiver before discharge process starts can have different size, depending on purposes.Preferably, its in the scope between 2 microlitres and 2 milliliters, especially preferably, in the scope between 50 microlitres and 250 microlitres.Because medium receiver is the ratio between 1:1 and 3:1 at the minimum percentage of elongation of upside place and extreme depth, can obtain good especially discharge characteristic.This ratio is larger, and chamber is larger with respect to the width of its degree of depth.If non-constant width, the equilibrium of punch-out enters with the discharge that repeats of medium and is no longer guaranteed.If ratio is too little, film extends to the end position of punch-out always, thereby has the danger that causes film fault.

Preferably, the matrix on upside has substantially flat upper sealing surface, and it is at least in part around chamber, and before punch-out is inserted in chamber, film at least major part is parallel to this sealing surface and is fixed on sealing surface on this.Therefore, film or at least its main portion can be used as substantially flat film, and needn't reproduce the complicated shape of upside.Thus, assembling is very simple.Substantially flat upper sealing surface is interpreted as flatness and mostly is 1 millimeter most.Therefore, sealing surface is arranged in two each other at most at a distance of between the plane of 1 millimeter.Thereby, the slight deviations of the flatness in the region of upper sealing surface on the one hand indicating sealing weld seam is preferably arranged on the upper sealing surface of matrix, it is around all drain passages with in the chamber of upper side opening, and in applied as thin films, guarantees at least in the region of sealing weld seam, to obtain being rigidly connected between film and matrix.On the other hand, if sealing surface has slight bending, so, can indicate the deviation of the required flatness of sealing surface, therefore, in applied as thin films, after sealing surface, this is also similar to cylindrical surperficial part, slight bending.This bending causes the stability of film resistance to deformation before film is finally applied to matrix completely, and its preceence will give supplemental instruction below.

Equally, the Transition edges that chamber and the part around chamber of the upside of matrix are separated is arranged in the plane of this sealing surface in eduction gear completely, and wherein, upper sealing surface is completely around chamber.But advantageously, Transition edges only extends to part, the especially main portion parallel with substantially flat sealing surface, yet, a part for Transition edges be arranged on upside with sealing surface additional facet slightly at angle on.At central authorities and sealing surface slightly at angle, preferably, this additional facet that becomes to be less than the average angle of 30 ° can be flat or slight bending completely.Under this deployment scenarios with additional facet at angle, chamber extends to the region of this additional facet, thereby a part for the Transition edges of chamber is arranged on this additional facet.The in the situation that of this layout, the film that seals the medium receiver being formed by chamber in the above is not exclusively designed to flat, but in transition region, between upper sealing surface and additional facet, is at least crooked or curling, preferably, has the radius that is less than 3 millimeters.This filling aspect that is arranged in eduction gear of the present invention is particularly advantageous, because film can only be fixed on matrix in the region of sealing surface at first, thereby in the region of sealing surface, it still keeps with it certain distance in the region of additional facet at first.Therefore, chamber still partially opens at first, thereby although film has partly been applied to matrix, still usable medium filled chamber even in large area.Only have when this happens, remainder remains the free part of film, and it is connected with additional facet subsequently, so that separate in medium receiver and the external world.In addition, in use, film is favourable at this curling of region of the open side of chamber, because actuating unit and punch-out have corresponding mobility, can make punch-out contact with film, at first transition region between period of energization between sealing surface and additional facet sealed chamber.In this case, because film is convex shape there, film is easy to start distortion in discharge process, because only there is at first uniaxial stressed state in film, but not two-dimensional state of stress.

But, except said method, also can use alternative, in said method, when medium receiver is filled medium, film has partly been fixed on matrix.Therefore, for example, film can only have when chamber is filled medium and is applied.An independent filling mouth also can be set in matrix, an auxiliary exhaust mouth is set alternatively, in filling, complete rear enclosed, for example sealing.

Actuating unit can be arranged to respect to the controlled mobility of matrix, and it is linear movable that actuating unit can be done with respect to matrix along straight line.But the layout that actuating unit is hinged on matrix is pivotly favourable.This special cost saving and be easy to produce.Preferably, this suitable hinge that can the hinged use of pivotable can be bistable hinge, and it has two each other at a distance of the pivot of a segment distance, the pivot that known for example glue spraying bottle is used.The in the situation that of bistable hinge, two relative end positions are stable, without external force maintains, keep, and midway location are non-stable, and the direction towards one of two end positions moves with respect to matrix to cause actuating unit.On the one hand, especially, when chamber filling medium, bistability is offset the actuating that is not intended to of eduction gear.On the other hand, in the situation that have a mind to activating, it causes actuating unit needn't resist the opposition of hinge and pushes and enter chamber.If actuating unit is designed to and as a whole of matrix, advantageous particularly.By this method, be convenient to especially produce.Here, if the connection between actuating unit and matrix realizes by film hinge, advantageous particularly.This film hinge is very beneficial for realizing actuating unit with respect to the controlled mobility of matrix.This actuating unit have can the deployment scenarios of pivot-hinge fitting under, if the pivot of actuating unit and extending abreast at the transition region or the transition line that are occurring in the film of sealing chamber between upper sealing surface and additional facet is considered to favourable.

If wish that medium discharges as spraying jet, need to make the medium vortex of ejection.This available various ways obtains.Therefore, particularly, can on the independent nozzle assembly on matrix or in being inserted into matrix, vortex geometric configuration be set.In addition, also can arrange breakpoint, its be arranged on the region of escape route and in discharge process by medium is exerted pressure and is opened, before being only and then positioned at discharge orifice, make after this breakpoint is opened, a narrow passage is suitable for producing vortex shape.

In the design of eduction gear of only having a medium receiver, preferably, its filling liquid, powder or paste medium, and if at least two chambers are set in matrix, there is other possible design result, particularly also relate to generation spraying jet, described chamber forms one first by receiver and a second medium receiver, wherein, preferably, at least two punch-out are set on actuation part, and it is inserted at least two chambers in the situation that actuation part moves.For example, the design with two medium receivers allows first blanketing gas in these medium receivers, preferably, fill air, it is in application, particularly after opening a breakpoint, flow in second medium receiver, to carry powdery MEDIA FLOW wherein to discharge orifice.In this layout, a punch-out needn't be also for second medium receiver.It can be such in a common actuation part or two different actuation parts, having design similar in the structure of two punch-out: by the first punch-out, liquid is transported to second medium receiver from first medium receiver, subsequently, by the second punch-out, be inserted in second medium receiver, described liquid is discharged with dissolved form with together with powder original in second medium receiver.Layout due to chamber, when using a plurality of punch-out, if for example the medium of first medium receiver carries out required fully mixing with the medium of second medium receiver, also can in order or carry out interim movement exerts one's influence, reduce the volume of medium reservoir cavity, then compound is squeezed out from second medium receiver.

About the generation of the spraying jet of ubi supra, if first medium receiver is connected in discharge orifice by escape route, second medium receiver is connected in escape route by feed path, may be advantageous particularly.In this layout, the medium of second medium receiver, liquid preferably, thereby be pressed in escape route when eduction gear activates, mix with the medium of discharging from first medium receiver there, preferably, mix with air.By this method, can produce reliably spraying jet.

About the generation of pressure point, the pressure point of the suitable layout of film as multilayer film and breakpoint is done in order to address in the above.If contact surface is arranged on matrix and actuating unit on, can obtain especially repeatably pressure point effect, in the situation that the actuating of eduction gear, it,, before medium is discharged by discharge orifice, enters tangential contact each other.Here, contact surface arranges and is designed to, and the actuation force that it must have continuous increase, makes actuating unit carry out continuous actuating and move.Obtain by this method pressure point effect.Adopt this layout, correspondingly, in actuation process, between contact surface, bump at first, operating personal must solve, contact surface or by increasing suitably deflection of actuation force, to can activate continuously, or lost efficacy in the region of the theoretical fracture location arranging for this reason, to can activate continuously.The pressure point effect obtaining by this method and the difference of aforementioned pressure point effect be especially, between period of energization in pressure point effect, the pressure of medium applies and needn't in medium receiver, occur.

The invention still further relates to a kind of eduction gear group with the eduction gear of a plurality of aforementioned type, the single eduction gear of this group is designed to a whole band of eduction gear connected to one another.The manufacture of this band is, its immediate member of matrix of each eduction gear of this band is connected to an integral body, or is connected in its next-door neighbour's member.By this method, obtain simple manufacturability, particularly simple operability.Preferably had use the eduction gear of film can be by being connected to each other, with the oriented approach of stipulating, grasped affected, with respect to as bulk goods, process the follow-up fill method of comparing, this is particularly advantageous.Particularly advantageously, the respective films that forms the eduction gear of described band is fixed on corresponding matrix, and fill area is still opened between matrix and film.Therefore, eduction gear is in pre-assembled state, and wherein, except medium still to be filled, eduction gear has comprised all formation components.But at this point, film, not yet on time finally completely in upside fixed position, therefore, still allows, by film and matrix opened areas in a distance, to carry out the filling process of medium.Only have afterwards just especially by making diaphragm seal in matrix, completely closed dielectric receiver.At complete fully enclosed state not yet, particularly advantageously eduction gear forms a band that spirals and roll, and this band causes these film portion of still freely stretching out to be protected and indeformable, and this can stop filling process below.

The invention still further relates to a kind of method of the eduction gear for the production of described type, wherein, from matrix and the film---matrix and film have unfilled medium receiver---that separately exist, start: film is fixed on the part around chamber the upside of matrix, on the subregion at the edge of chamber, film is not fixed on matrix, medium receiver by film and film still the intermediate space between the subregion at loose edge be filled liquid, paste or powdery medium.Finally, film is also fixed on this subregion at edge.

The method makes it available its all component and has approached eduction gear, to approach completion status at this, from the manufacturer of eduction gear, is transported to the tucker that is generally positioned at another place.This tucker, by the opened areas filling medium receiver between film and matrix, completes fixation procedure, particularly seal process subsequently.

Particularly advantageously, before filling at the sealing surface place of upside fixed film, after filling at the additional facet place of upside fixed film.By this method, film can remain on substantially flat state, until fill.

The specific embodiment

Eduction gear of the present invention has many stable features.First, with reference to Fig. 1, these stable or most of stable features of all embodiments are described.

Eduction gear 10 of the present invention has plastic base unit 20, with respect to the actuating unit 40 of base unit activity and the film 50 that is fixed on the upside 22 of base unit 20.

Base unit 20 has discharge orifice 26, this discharge orifice can be set directly in the integral component of base unit 20, or in the first embodiment of Fig. 1 a and 1b, can be formed by the nozzle assembly 27 separating, it is arranged in base unit 20 and is fixed to regularly on this base unit.In the upside of having addressed 22 of base unit, chamber 70 is set, it forms the main portion of the outer wall of medium receiver 60.This chamber 70 is connected to discharge orifice 26 by interface channel 76, and it divides on several upsides 22 that are partly arranged on base unit 20 as a groove.In the open side of chamber 70, medium receiver 60 is to be sealed by film 50 with mode identical in Fig. 1 b, and for the purpose of understanding better, it is separately shown in Fig. 1 a, apart from base unit 20 certain distances.This film 50 all drain passages of sealing and towards the chamber of the upside 22 of base unit 20, make here, as expected, and before activating and do not have medium to miss between period of energization.

For medium is discharged from medium receiver 60, actuating unit 40 is set.It can be movable pivotally with respect to base unit 20 around pivot 4 by hinge 42 along the direction of arrow 2.As shown in block diagram 1a and 1b, Yi Ge spine is set on actuating unit 40, it forms a punch-out 44.The profile of this punch-out 44 is at least substantially corresponding to the shape of chamber 70.Punch-out 44 is arranged on actuating unit 40, makes by actuating unit 40 pivotable with respect to base unit 20 along the direction of arrow 2, and punch-out is correctly inserted in chamber 70.

Above-mentioned feature meets all embodiments shown in this specification sheets.But some supplementary features are not identical in all embodiments, or sometimes only in single embodiment, realize.

About the embodiment of Fig. 1 a and 1b, it operates in Fig. 1 d to 1f and is explained, and will address following other different characteristic.The upside 22 of base unit 20 has the upper sealing surface 23a of general flat, and its direction towards the sensing curved edge 24 of actuating unit 40 in sealing surface 23a additional facet 23b at angle changes.Chamber 70 extends beyond this edge 24, makes the Transition edges 25 between sealing surface 23a or additional facet 23b and chamber 70 only partly be parallel to the plane of sealing surface 23a.As Fig. 1 b illustrates, film 50 is also subdivided into a main portion 52a and a slave part 52b each other at angle due to face 23a, 23b, and in all cases, described main portion and slave part are same high, and are separated from each other by a curved edge 54.Another different characteristic of the embodiment of Fig. 1 a and 1b is to arrange an application chamber 72 between medium receiver 70 and interface channel 76.This application chamber 72 has bottom, and this bottom, a little less than face 23a, therefore, when film 50 is sealed in upside 22, does not produce the connection of film 50 here.Bridge cut-off 74 is fixed on flat wide application chamber 72.This narrow bridge 74 forms a breakpoint, upstream application chamber 72 and below interface channel drain be partly to extend between chamber 70, application chamber 72 and escape route 76 are separated around face by seal weld 78 and upper sealing surface 23a and additional facet 23b's.After film 50 is used, from the state of Fig. 1 a, be transformed into the state of Fig. 1 b, heat-seal process, guarantees that at least in the region of sealing weld seam 78, obtaining failure-free between the upside 22 of base unit 20 and the bottom side of film 50 connects.

The another one different characteristic of the embodiment of Fig. 1 a and 1b draws from Fig. 1 c, and it illustrates the cross section through film 50.From this figure, film 50 is designed to a laminated film, has upper film layer 50a and lower thin layer 50b, be both made of plastics, and be polyethylene in this case.Between this upper film layer 50a and lower thin layer 50b, arrange an interlayer 50c, it is an aluminium foil layer.

Fig. 1 d to 1f illustrates the operation of eduction gear 10.Fig. 1 d illustrates starting state with cross-sectional side elevational view.In this starting state corresponding to Fig. 1 b, the medium receiver 60 that medium receiver is defined with respect to the external world by the wall of chamber 70 and the downside of film 50, is filled liquid dielectric 62, is the vaccine 62 of nasal-cavity administration in this case.In order to discharge this medium, eduction gear 10 is held in the nostril that discharge orifice 26 is positioned at user.Then, actuating unit 40 in the mode shown in Fig. 1 e the direction pivotable around the pivot 4 being limited by film hinge 42 along arrow 2.During this process, after surpassing the state shown in Fig. 1 e, soon, between punch-out 44 and film 50, there is tangential contact, this initial tangential contact occurs in the region of the curved edge 54 of film 50.The in the situation that of actuating unit 40 continuous pivoting action, punch-out 44 is pressed in chamber 70 in the region at edge 54, and film 50 is out of shape simultaneously.In film 50, have tension, wherein, with reference to Fig. 1 b, tension only produces on horizontal direction 6, because film stretches upwards this side.Initial not along direction 8 stretching, extensions of quadrature with it, so only there is coaxial tension, it does not increase the required power of annoyance level that is applied to.But along with actuating unit 40 increases pivotable, the pressure in medium receiver 60 and application chamber 72 increases thereupon.Because application chamber 72 designs very flatly, but has larger area, thus film 50 in the region of application chamber 72, by a small amount of medium, upwards pressed, thereby obtain film 50 with respect to the separating force of bridge cut-off 74.Pressure in medium receiver 60 causes the drag to the increase of the continuous motion of actuating unit 40.In addition, the drag of this increase is supported, because aluminium foil layer 50c constantly stretches along direction 6, until the limit of its breaking extension.Paper tinsel layer 50c almost breaks simultaneously, and other thin layer 50a, 50b are unaffected, and film 50 is separated with narrow bridge 74.It is this moment unimpeded that medium 62 leads to the path of discharge orifice 26.High fluid pressure in medium receiver 60 and this moment under the higher application force of actuating unit 40, medium is expressed into discharge orifice 26 from medium receiver 60 by interface channel 76, use there with the form of spray 64.Especially as shown in Figure 1 f because the shape of punch-out 44 is designed to the shape complementarity with chamber 70, so almost all media from medium receiver 60, discharge.Also advantageously, the outlet of medium receiver 60 is arranged in the side in the face of the pivot 4 of actuating unit 40, and therefore, the motion path that punch-out 44 enters chamber 70 is conducive to avoid medium to flow along the direction of interface channel 76.Fig. 1 g illustrates again eduction gear 10, and it is after discharge process completes.

Fig. 1 h and 1i illustrate the generation of eduction gear 10.As shown in these figures, film 50 is only sealed on the upside 22 of base unit 20 at first in the region of upper sealing surface 23a, and in the region of additional facet 23b, is not sealed on the upside of base unit for this reason at angle.By this method, cause above-mentioned state shown in the drawings, wherein, film 50 is flush arrangement substantially still.In the region of additional facet 23b, cause thus the entrance 66 that leads to medium receiver 60 to stay open at first.Therefore, eduction gear 10 can be provided to tucker with the state shown in Fig. 1 h and 1i by the manufacturer of eduction gear.Tucker can pass through above-mentioned opening 66 filling medium receivers 60, subsequently the free end 52b of film 50 is sealed in to additional facet 23b, thereby in order to complete eduction gear.

Fig. 1 j and 1k illustrate particularly advantageous process here.Wherein, eduction gear 10 is made a continuous band 100, and it comprises a plurality of eduction gears 10, and for this reason, base unit 22 is connected to each other along lateral edges 28.Eduction gear 10 can be rolled at the still unfilled state of corresponding diagram 1h and 1i, to form a wreath, as shown in Fig. 1 j.By this method, film 50 still freely end 52b avoid mechanical action, therefore can not seal unintentionally opening 66, need described opening 66 to fill eduction gears 10 later.Eduction gear 10, after filling by these openings 66, can return a state of coiling with 100, as shown in Fig. 1 k.Therefore, remover can save space-efficient mode and stores and transport.

Therefore, eduction gear of the present invention allows to obtain the discharge medium that very favorable production prices, simple operability and height can number of iterations.

The difference of the embodiment shown in Fig. 2 a and 2b and previously presented eduction gear is only a main aspect.Therefore, the upper sealing surface 23a in this second embodiment on the upside 22 of base unit 20 is designed to slight bending, especially as shown in Figure 2 b.This slight bending causes film 50 also with the form of slight bending, in fact, with the surperficial form partly on the face of cylinder, is fixed on sealing surface 23a.By this slight bending of almost not seeing, with respect to the free end 52b of film 50, can improve sizable stability in Fig. 2 a.Therefore,, in the transportation of the eduction gear 10 completing in the part for filling, than last embodiment, guarantee that better film 50 even can not close unintentionally import 66 before filling.

In the embodiment shown in Fig. 3 a to 3c, especially there are two different characteristics.On the one hand, in this embodiment, the upside 22 of base unit 20 is designed to flat substantially.Here do not arrange and sealing surface 23 additional facet at angle, this additional facet extends to the region that chamber 70 extends therein.Therefore, in this embodiment, corresponding film 50 is not shown in Fig. 3 a and 3b, and initial, before film 50 is used, the medium receiver 60 being formed by chamber 70 and film 50 is filled completely, as shown in Figure 3 c.The another one different characteristic of this embodiment shown in Fig. 3 a to 3c is, hinge 42 is designed to bistable hinge, and it has the pivot 4a to 4c of a plurality of spaced segment distances that formed by film hinge.Draw thus, actuation part 40 or at an end position shown in Fig. 3 a to 3c, or at relative end position, aspect moment of torsion, work all the time, wherein, punch-out 44 is inserted in chamber 70.Therefore,, during 60 carryings of medium receiver and filling, guarantee that actuating unit 40 can not disturb unintentionally filling process.In addition, guarantee that the applying of power that actuation part 40 obtains discharge process do not stop the restoring force being produced by hinge 42.

In the embodiment shown in Fig. 4 a and 4b, arrange two medium receivers.Except medium receiver 60---it designs in mode identical in the situation with the embodiment shown in Fig. 1 a to 1c, has a second medium receiver 60', its equally the chamber 70' in base unit 20 form.Two medium receivers 60,60' are connected by an interface channel 76 each other.As the escape route 76' of extendible portion of interface channel 76 from second medium receiver 60'.Interface channel 76 and escape route 76' both have a bridge cut-off 74,74', it is with the identical mode effect of the bridge cut-off 74 with the embodiment shown in Fig. 1 a to 1c, and only in upstream medium receiver 60,60' and upstream application chamber 72,72', opens predetermined minimum pressure in the situation that.Corresponding film is shown in the embodiment shown in Fig. 1 a and 1b, but not shown in this embodiment.

Eduction gear shown in Fig. 4 a and 4b for mixing two media before discharge process starts.Therefore, especially can in medium receiver 60, provide liquid, and have powdery medium in medium receiver 60'.When the eduction gear 10 shown in Fig. 4 a and 4b is when activating with the identical mode shown in Fig. 1 d to 1f, first in medium receiver 60, produce pressure, the liquid wherein comprising, after crossing bridge cut-off 74, is transported to second medium receiver 60' thus.In this counteraction, also form excess pressure, at the second punch-out 44', enter in the process of the second chamber 70', described excess pressure is high must be enough to also cause that film is separated with the body portion in the region of bridge cut-off 74'.Therefore, blending agent is discharged by discharge orifice 26 subsequently.

In the eduction gear shown in Fig. 5 a to 5c, different characteristic is, obtain an accurate especially pressure point, because pin formula retainer 48 is set on actuation part 40, it is inserted in the process with respect to matrix 20 pivoting actions at actuation part 40 in the opening 30 of matrix 20, is wherein provided with the fixedly meshwork 32 of horizontal expansion.Therefore, actuation process is interrupted in position shown in Fig. 5 a and 5b, until act on, the power of actuating unit 40 is large must be enough to cause the fixedly fracture defect of meshwork 32.Only have when these fixing meshwork whens fracture, actuating unit 40 just can continue with respect to matrix motion, thereby the mode having illustrated with Fig. 1 d to 1f is carried out discharge process.

Eduction gear 10 shown in Fig. 6, as the embodiment shown in Fig. 4 a and 4b, has two medium receivers 60,60', its in all cases the chamber in base unit 20 form.In these chambers, only have the chamber 70 of medium receiver 60 in Fig. 6, to identify immediately.Chamber 70' illustrates with the form of dash line.Different from the embodiment shown in Fig. 4 a and 4b, medium receiver 60,60' are not directly connected by an interface channel.Alternatively, medium receiver 60 is connected in a discharge orifice 26 by an escape route 76, and less medium receiver 60' leads to a feed path 75, and this feed path is the not far escape route 76 that leads to before discharge orifice 26.Eduction gear shown in Fig. 7 is for generation of atomization.For this reason, only have air to be stored in medium receiver 60, and liquid pharmaceutical is present in medium receiver 60'.When having, be suitable for the punch-out 44 of chamber 70,70', during the direction pivotable of the actuation part 40 of 44' around pivot 4 along arrow 2, in two medium receivers 60,60', there is superpressure simultaneously, bridge cut-off 74,74' in escape route 76 and service duct 75 opens thus, makes air and the liquid in medium receiver 60' in medium receiver 60 similar simultaneously mobile towards the direction of discharge orifice 26.Liquid and air nearby mixed before discharge orifice 26, to discharge spraying jet.

In the embodiment shown in Fig. 7, also arrange two medium receivers 60,60', in all cases, its chamber 70,70' in matrix 20 forms.But here, different features are, actuation part 40 only has a punch-out 44, and punch-out is arranged to, enter in medium receiver 60 larger in two medium receivers during around pivot 4 pivotable at actuation part 40.In medium receiver 60, produce superpressure thus, first it cause film 50 separated with bridge cut-off 74.Once this situation occurs, air just flows into medium receiver 60' from medium receiver 60, so also under pressure, makes film 50 separated with the second bridge cut-off 74'.Once this situation occurs, air can flow towards the direction of discharge orifice 26, carries there the mealy medicine 62' being stored in second medium receiver 60', flows to discharge orifice 26.

In the embodiment shown in Fig. 8, two medium receivers 60,60' are also arranged in matrix 20, and it is connected by an interface channel 76 each other.Bridge cut-off 74,74' are arranged in successively medium receiver 60 before and afterwards, with film 50, are sealed in initial state.In this embodiment, exist first actuation part 40 and one can be with respect to the first actuation part 40 the second actuation part 40' around the second pivot 4' pivotable.Contain liquid dielectric 62 in medium receiver 60, and contain powdery medium 62' in medium receiver 60'.Actuating about the eduction gear 10 shown in Fig. 8, first, two actuation parts 40,40' are together around pivot 4 pivotables, until the pressure that punch-out 44 produces film 50 in the region of first medium receiver 60 is enough to make film 50 separated in the region of bridge cut-off 74 with matrix 20.This causes liquid 60 to enter second medium receiver 60'.Because actuation part 40,40' are at first only in the actuation part application of force, so during it enters the chamber 70 of first medium receiver 60, the second punch-out 44' does not enter the second chamber 70' yet because actuation part 40,40' due to joint 42' pivotable mutually.Bridge cut-off 74 is opened the pressure producing in rear medium receiver 60 and is also still not enough to also in the region of the second bridge cut-off 74', make film 50 separated with matrix 20, and initial two media 62,62' are remained in medium receiver 60' together.Only have when the second punch-out 40' is also inserted in chamber 60' afterwards, film 50 is just separated with bridge cut-off 74, to open the path of leading to discharge orifice 26.Once this situation occurs, the compound of two media just flows out.

Those skilled in the art can do other and improve, and do not exceed the scope of the present invention defined in claims.
