Embodiment

[47] with reference to Fig. 1, this figure with the decomposition view mode represent one with corresponding dosage indicator of a specific embodiments of the present invention or counter.Certainly, this uses a just embodiment, and a plurality of elements of this indicator can be realized with different modes.Or rather, the present invention relates to make the activation part of described counter start, and indicating device can be an any kind certainly, is not limited to the indicating device shown in the figure.

[48] or rather, indicator according to the invention comprises at least one measuring element 5, an actuation element 1 and a driving element 6.Actuation element 1 can move axially, preferably translation, and measuring element 5 rotations are installed in around the described shifting axle of actuation element 1.Be provided with driving element 6, so that the rotation that moving axially of actuation element 1 converted to measuring element 5 is moved.

[49] it is pointed out that indicator is assembled in the bottom of a reservoir 10 in the example of Fig. 5 (and Figure 18-20), in this case, actuation element 1 (not shown among Fig. 5) can be similar with actuation element shown in Figure 1.In this case, measuring element 5 moves to the direction of described driving element 6.On the contrary, in the example of Fig. 6---wherein indicator laterally is installed on a reservoir 10, and for example actuation element 1 can what connect together with driving element 6 be that spherical projection 1 forms to small part by one.When reservoir 10 is mobile vertically downward described in the configuration shown in Figure 6, this projection 1 causes described driving element 6 to move axially to the direction of meter 5.

[50] in the above under two kinds of situations shown in Fig. 5,6, rotation is fixing mutually for actuation element 1 and driving element 6, and driving element 6 comprises flexibility or

elastomeric element

7,8, and they can move axially a rotational motion that converts measuring element 5 to one of actuation element 1 and/or driving element 6.

[51] in the embodiment shown in fig. 1, indicator comprises that one forms the cover piece of actuation element 1, and this cover piece can be provided with one and observe fenestra 60.One display disc 2, a drive plate 3 and a boot disk 4 can between place between described actuation element 1 and the described measuring element 5.

[52] display disc 2 can comprise some colored fan sections or zone similarity 120,121, and one and the fenestra 125 that relatively is provided with of the observation fenestra 60 of actuation element 1.Also can be provided with a guide rail 126 and a center pit 127 in the described display disc 2.Equally, drive plate 3 can support the second drive pin (not shown) that first drive pin 130 and of an interlocking in the guide rail 126 of display disc 2 is positioned at an opposite side of described driving-disc.Drive plate also can be provided with a linear fenestra 136.At last, boot disk 4 can be provided with the opening 144 that linear guide seat 149 and that fenestra 145, a central aperture 147, that adapts with the fenestra 60 of driving element 1 be suitable for accepting drive plate 3 passes through for the following drive pin (not shown) that makes drive plate 3.Then all these elements are assembled on the central shaft 157 that is located on the measuring element 5, measuring element 5 also comprise one to small part be spiral type portion or track 158, it can cooperate with the following guiding or the drive pin (not shown) of drive plate 3.In this example, for example 200 dosage can be set in reservoir, last 150 dosage are presented in the observation fenestra 60 by two fan sections 120,121 of display disc.During beginning, when fan section 120 is in the observation fenestra 60 fully, this means that reservoir is full.Then, along with dosage is distributed gradually, display disc 2 rotates, and fan section 121 can replace the position of fan section 120 in observing fenestra 60 gradually.The rotation of display disc 2 realizes by measuring element 5, because the drive pin (not shown) cooperates with the spiral part of track 158 down, measuring element 5 drives drive plate 3 translation in its guide seat 149 when rotating.Because last protruding pin 130 cooperates with guide rail 126, this translation of drive plate 3 causes display disc to rotate.At last, when only being left 50 dosage in the reservoir, drive plate 3 arrives end positions, and therefore is illustrated in indicating device 50 or digital more precisely appearing in the fenestra 60 and 125 of actuation element 1 and display disc 2 on the measuring element 5.Then, because type portion 158 is circular substantially, the later action of indicator no longer makes display disc 2 move, and drive plate 3 is moved, and has only measuring element 5 to rotate in actuation element 1, and the remaining dosage number that successively decreases manifests gradually in the reservoir so that make.Certainly, this is a specific embodiments, no matter for indicating administered number, still indicates dosage number to be allocated in the reservoir, can consider the indicating mode that other is any.

[53] come off for fear of indicator, actuation element 1 preference card is in driving element 6, and in this case, driving element 1 can endwisely slip in described driving element 6.This still is an embodiment, and these different elements may be embodied to cooperation in a different manner.

[54] according to the present invention, preferably the measuring element made from a thin disk-form 5 comprises on the one hand and is used for passing appreciable indicating device 50 in the observation fenestra 60 that is located at lid 1, comprises that on the other hand one is used for the dentition 9 that cooperates with the

elastomeric element

7,8 of driving element 6.These elastomeric elements comprise at least two flexible pawls.When start element 1 from its rest position when its activated position moves, at least one first flexible pawl 7 cooperates with the described dentition 9 of measuring element 5.Described measuring element 5 is rotated to a counting direction.The elastomeric element of driving element 6 also comprises at least one second flexible pawl 8, when start element 1 from its activated position when its rest position is returned, this second flexible pawl 8 cooperates with the described dentition 9 of measuring element 5, so that described measuring element 5 is rotated to identical counting direction.In other words, the actuation cycles of indicator is divided into two different parts, one second portion of realizing when its rest position is returned from its activated position at actuation element from first that its rest position realizes when its activated position moves and at actuation element.

[55] Fig. 2,3,4 more properly represents the described

flexible pawl

7,8 of driving element 6.Certainly,, but can consider any amount of these flexible pawls even have only one first flexible pawl 7 and one second flexible pawl 8 in an example shown, and these pawls not necessarily as shown in the example on the diameter relatively.As can seeing among Fig. 2-4, the first flexible pawl 7 preferably includes a free end that is approximately tip shape, and the second flexible pawl 8 preferably includes a free end that is roughly coupler body shape.Referring now to Fig. 3, the fit system of the first flexible pawl 7 and the dentition 9 of measuring element 5 as can be seen, promptly its free end cooperates with a tooth 9a of described dentition.Fig. 4 represents cooperating between the second flexible pawl 8 and the same dentition 9 in a similar fashion, and in this case, the hook-type free end of this second flexible pawl 8 cooperates with a tooth 9b of the dentition 9 of measuring element 5.Advantageously, each tooth of this dentition 9 comprises the dip plane that a stop surface and is connected the stop surface of the tooth of direct neighbor in this stop surface and the described dentition 9.Therefore, when the user actuated actuation element 1, the relative driving element 6 of this actuation element moved axially, and did not realize relative to the rotating of driving element 6, thereby made the

flexible pawl

7,8 of actuation element 1 elastic compression, or made their elastic deformations.Then describe with reference to Fig. 7-9 as following, the distortion of the first flexible pawl 7 causes measuring element 5 to rotate.When start element 1 when its rest position is returned, two

pawls

7,8 return elastically their undeformed positions, and between this moving period, the second flexible pawl 8 cooperates with dentition 9, so that also cause measuring element 5 to rotate towards counting direction, the counting direction that this counting direction gives measuring element 5 by the first flexible pawl 7 during with actuation cycles first is identical.The second portion of this actuation cycles is shown in Figure 15-17 more accurately.

[56] now more accurately with reference to Fig. 7-17, can see, Fig. 7-the 11st, the interactional synoptic diagram during the complete actuation cycles of expression counter between the dentition 9 of the first flexible pawl 7 and measuring element 5, and Figure 12-17 is illustrated in cooperating between the same dentition 9 of the second flexible pawl 8 and measuring element 5 during identical complete count cycle of indicator in a similar fashion.These figure side by side represent during the same actuation cycles two

flexible pawls

7,8 at synchronization.

[57] clearerly be, when actuation cycles begins, when the user with actuation element 1 from its rest position when its activated position moves, the free end of the first flexible pawl 7 is relative with the stop surface of a tooth 9a of dentition 9.Shown in Fig. 8,9, along with the activated position of actuation element 1 to it moves, axially near driving elements 6, this causes first flexible pawl 7 elastic deformations for measuring element 5, first elastic claw 7 stop surface of tooth 9a that reclines then, and this causes measuring element 5 to rotate around rotating shaft.Simultaneously, as what see among Figure 12-14, the preferred free end for hook-type of the second flexible pawl 8 slides along the dip plane of tooth 9b ' that directly is positioned at the tooth 9b next door of dentition 9.Particularly, can see that near driving element 6, this causes second flexible pawl 8 elastic deformations to measuring element 5 gradually, therefore makes its free end slide on this dip plane with reference to Figure 12-14.When arriving the position of Figure 14, can be more clearly visible in the little details as the amplification of Figure 14, the free-ended edge of described hook-type of the second flexible pawl 8 carries out the transition to the stop surface of tooth 9b from the dip plane of tooth 9b '.The elasticity of this second flexible pawl 8 of the transition between Figure 14 and Figure 15 by being actuated distortion by actuation element 1 and carrying out automatically.From this constantly, when the free end of the second flexible pawl 8 is in tooth 9b, and when the start element from its activated position when its rest position is returned, measuring element 5 can be gradually axially away from driving element 6, this will make automatically the second flexible pawl (and first flexible pawl 7) again elasticity get back to its former beginning and end deformation position.In this process, and as clearly illustrating among Figure 15-17, the free end of the second flexible pawl 8 cooperates with the stop surface of tooth 9b, rotates around described axially identical with front counting direction so that spur described measuring element 5.Simultaneously, as seeing among Figure 10-11, the free end of the first flexible pawl 7 slides along the dip plane of tooth 9a.At last, in the rest position of actuation element, the first flexible pawl 7 will be interior in place at directly adjacent with the described dip plane of tooth 9a tooth 9a ', and then indicator is ready to next actuation cycles.

[58] above-described indicator has many advantages.For example, particularly, it is without any need for preventing ratchet that measuring element 5 rotates in the opposite direction to the side that provides with two

flexible pawls

7,8 or similar system.In fact, when one of them of two

flexible pawls

7,8 slided along the dip plane of a tooth each time---this may cause measuring element to move round about by friction, another flexible pawl makes measuring element rotate to counting direction, has therefore overcome the effect of these possible frictions.

[59] on the other hand, implement in the modification at first shown in Figure 18-20, be that indicator is positioned at reservoir 10 bottoms, can before moving in the main body 150 of reservoir 10 at inhalator, realize to the first of the actuation cycles that its activated position moves corresponding to the rest position of actuation element 1 from it.Is exactly this situation from the deformation resistance of the

flexible pawl

7,8 of indicator less than moment of the deformation resistance of dosage valve 100.Such result is that actuation cycles begins preceding startup at the actuating travel of valve (or pump) 100, has so just eliminated any danger of underdosage.In fact, arrive the moment of activated position from actuation element 1, the user continues to exert pressure on this actuation element 1, can cause reservoir 10 to move, and move when beginning from this, the free end of the second flexible pawl 8 carries out the transition to 9b from tooth 9b ', shown in Figure 14,15, even therefore the start of valve (or pump) is a part, can guarantee that also the complete count cycle of indicator finishes.

[60] in the second enforcement modification shown in Figure 6, indicator is laterally arranged with respect to reservoir 10, and one and the actuation element that connects together of driving element 6 thereby moving axially of reservoir 10 converted to moving radially of driving element 6, so that measuring element 5 is rotated.In this case, start the actuation cycles of indicator in the time of can beginning at the stroke of reservoir 10, thereby indicator is actuated before product dispensation.

[61] Figure 21-36 expression another embodiment of the present invention, it is with the main difference of previously described embodiment: measuring element 5 is not that the axle that moves axially around actuation element 1 rotates, but moves axially a vertical substantially rotation around one with this.In this embodiment, the same side that is positioned at of the modification of indicator and Fig. 6, but actuation element 1 and the driving element 6 realized in the monomer mode here move axially with the longitudinal axis of reservoir along main body (and reservoir), so that measuring element 5 is rotated.The lid of not shown enclosed indicator.

[62] particularly as seeing among Figure 22, driving element 6 is can axially movable mode being installed in the main body 150.Advantageously be provided with stop member, so that form to this axially movable block piece.These stop members can comprise that one of main body 150 can cooperate with a fenestra 25 of driving element 6 protruding pin 35.Also can consider other stop member.Each of

flexible pawl

7,8 supports a tooth 7 ', 8 ' that cooperates with the dentition 9 of measuring element 5 respectively.Tooth 7 ', 8 ' shape are inverted, and make that first tooth 7 ' pushes away tooth 9a, and when reservoir 10 rose in main body 150 again, second tooth 8 ' drew a tooth 9b when reservoir 10 descends in main body 150.This cycle is shown in Figure 26-36, and the periodic group of describing with reference Fig. 7-17 seemingly.Therefore be not described in detail below.But can notice that bottom line B is expressed by the both sides of indicator respectively, so that observe relatively still moving axially of the measuring element 5 of axial restraint of driving element 6.

[63]

flexible pawl

7,8 axially is being a substantially rigid preferably, and only with the perpendicular direction of moving axially of driving element 6 be flexible.

[64] advantageously, driving element 6 comprises some elastomeric elements 21,22, as the flexure strip that cooperates with the corresponding convex shoulder 31,32 of main body 150, so that be formed for the retracing spring of driving element.

[65] but actuation element 6 comprises in addition that preferably one supports the parts 24 of the axial deformation of actuation element 1.Can after reaching the blocking position that protruding pin 35 and fenestra 25 determine, continue moving axially of actuation element 1 (therefore also having reservoir 10) like this.Can fix this like this stops, thereby make when reservoir descends (when first tooth 7 ' pushes away dentition 9), obtain the rotation of lucky half tooth, and under elastomeric element 21,22 effect at reservoir 10 and when therefore driving element 6 rises (when second tooth 8 ' draws dentition 9) obtain the rotation of residue half tooth.The start of valve generally needs a big stroke, therefore needs big moving axially of reservoir 10, and the deformable segment 24 of driving element 6 allows to continue moving axially of reservoir, up to its terminal point.In addition, this system can start indicator before the beginning allocated product.

[66] advantageously, driving element 6 comprises that in addition one extends axially part 23 with the guide member of main body 150 as what a track 37 cooperated, perhaps also has lid pawl (not shown), so that guide this element when driving element 6 moves, and/or avoid harmful and move.Also can consider other guide member.

[67] compare with the indicator of Fig. 6, the indicator of Figure 21-36 especially has thinner advantage, so this can reduce the external dimensions of device.

[68] more advantageously, in above-mentioned different modification, can be provided with: the start of indicator is carried out in two sub-sections, promptly one before the dispensing orifice 151 distributing fluids products that pass main body 150 first and the second portion after the fluid product dispensation.In this case, indicator does not move between effective allotment period at product, so the accurate, reliable of it moves with user's starting device so that realize that the mode of product dispensation is irrelevant fully.

[69] certain, compare with the description of front, can with shown in the different mode of mode form indicator.Particularly, the first and second flexible pawls 7 can be different with the position with 8 shape, and condition is that the first flexible pawl should be able to promote measuring element 5 and rotates, and the second flexible pawl can spur same measuring element 5 and rotates to same direction then.Certainly can consider also that promptly the first flexible pawl 7 can spur measuring element 5 with the function of the first and second

flexible pawls

7,8 conversely, and the second flexible pawl 8 can promote measuring element 5.Another advantage of indicator according to the invention is that it includes only a unique element that is provided with dentition, these many indicators with prior art are opposite, in the prior art, for fear of the danger of underdosage, be provided with two or more dentitions of separating so that allow the safety of indicator and starting reliably.

[70] those skilled in the art can consider that also other improves, and is no more than the scope of claims regulation.
