NEBULIZER

The present invention relates to a nebulizer according to the preamble of claim 1, 9 or 10.

The starting point for the present invention is a nebulizer as illustrated in WO 2006/125577 A2. The nebulizer has, as a reservoir for fluid which is to be atomized, an insertable rigid container having an inner bag containing the fluid and a pressure generator with a drive spring for delivering and atomizing the fluid. Preferably, the container is pre-installed in the nebulizer in the delivery state. Before being used for the first time a securing member of the nebulizer has to be opened or removed so that a housing of the nebulizer can be completely closed. Thus, the pre-installed container is opened by a delivery tube piercing a sealing and a septum to fluidically connect to the inner bag of the container. By rotating a lower housing part of the housing of the nebulizer the drive spring can be put under tension and fluid can be sucked into a compression chamber of the pressure generator. Simultaneously, the container is moved into the lower housing part in a stroke movement within the nebulizer and when tensioned for the first time the container may be pierced through its base by a piercing element in the lower housing part to allow venting of the container. After manual operation of a locking element the drive spring is released and the fluid in the pressure chamber is put under pressure by the drive spring and is delivered or atomized through a nozzle into a mouthpiece as an aerosol, without the use of propellant gas.

Object of the present invention is to provide a nebulizer with optimized or facilitated handling.

The above object is achieved by a nebulizer according to claim 1, 9 or 10. Preferred embodiments are subject of the subclaims.

According to one aspect of the present invention, the nebulizer comprises a securing member preventing fluidic connection or opening of the container in a delivery state. The container is already disposed in the nebulizer in the delivery state, i.e. pre-installed. The securing member can be manually opened, removed, released or destroyed to allow fluidic connection or opening of the container, in particular before or for first use of the nebulizer. The securing member comprises an actuator to open, remove, release or destroy the securing member. This allows optimized and/or facilitated handling. In particular, it allows intuitive operation of the nebulizer. For example, a user will intuitively grab, tear, tilt, pull or push the actuator to open, remove, release or destroy the securing member and, then, completely close the nebulizer for using the nebulizer.

According to a further aspect of the present invention, the securing member comprises a pre-determined breaking line along which the securing member can be opened, in particular by pulling the actuator. This allows facilitated and/or optimized handling. In particular, it allows defined opening or removal of the securing member.

According to another aspect of the present invention, the securing member can be opened, released or destroyed by turning a (lower) housing part of the nebulizer relative to the housing or upper housing part of the nebulizer, i.e. by torsioning the securing member or a preferably sleeve-like body thereof. In particular, the securing member or body is opened along a pre-determined breaking line by this torsioning. This facilitates the handling.

According to a further aspect of the present invention, the securing member is made of one piece and/or such that it can be opened, removed, released or destroyed in one piece. This allows an optimized or facilitated handling.

Preferably, the nebulizer comprises a housing part that is connectable to a housing of the nebulizer in a non-detachable manner after inserting or pre-installing the container. According a further aspect of the present invention, the housing part can be pre-mounted in another position, preferably in another rotational position, on the nebulizer or its housing than in the delivery state such that the housing part can be detached for inserting the container. This pre-mounting allows to re-open the nebulizer or its housing for inserting the container. Thus, the container can be inserted or pre-installed after producing the nebulizer. This allows optimized or facilitated handling.

The above aspects of the present invention and other aspects of the present invention as described the following can be realized independently from each other or in any combination.

A basic idea of the present invention is that even in its delivered state the nebulizer has a closed container provided therein and the nebulizer is constructed so that the container is opened inside the nebulizer before or during the first use of the nebulizer. This basic idea is called in the present invention also “pre-installed container”. This makes operation easier as there is no need to open the nebulizer, insert the container and close the nebulizer. Moreover, undesirable soiling or damage to the nebulizer caused by incorrect handling of the end-user when inserting the container can thus be prevented. Accordingly, there is better operational safety as it is impossible for the container to be wrongly inserted or otherwise misused during insertion.

Preferably, the container is not replaceable and in particular cannot be removed. This again leads to easier operation and hence improved operational reliability. This also prevents the nebulizer from being used or re-used in an undesirable or unauthorized manner.

In particular, the nebulizer cannot be opened and a lower housing part cannot be removed in order to replace the empty container with a full one in an undesirable manner.

The combination of the pre-installed container and the construction which makes the container non-replaceable results in particularly easy operation and high operational reliability as the user can only use the nebulizer as a single-use item until the container is empty, and undesirable or unauthorized further use of the nebulizer is prevented by the fact that the container cannot be replaced.

However, correspondingly easy operation and improved operational reliability for the user can also be achieved if the container is pre-installed at the pharmacy, for example, i.e. by trained staff, and optionally opened at the same time provided that the container is made non-exchangeable, in particular the nebulizer cannot be opened by the user (end-user).

FIGS. 1 and 2 show a known nebulizer 1 for atomizing a fluid 2, particularly a highly effective pharmaceutical composition, medicament or the like, diagrammatically shown in a non-tensioned state (FIG. 1) and in a tensioned state (FIG. 2). The nebulizer 1 is constructed in particular as a portable inhaler and preferably operates only mechanical and/or without propellant gas.

When the fluid 2, preferably a liquid, more particularly a pharmaceutical composition, is nebulized, an aerosol 14 (FIG. 1) is formed, which can be breathed in or inhaled by a user. Usually the inhaling is done at least once a day, more particularly several times a day, preferably at set intervals, depending on the complain or illness from which the patient is suffering.

The nebulizer 1 is provided with or comprises an insertable container 3 containing the fluid 2. The container 3 thus forms a reservoir for the fluid 2 which is to be nebulized. Preferably, the container 3 contains an amount of fluid 2 or active substance which is sufficient to provide up to 200 dosage units, for example, i.e. to allow up to 200 sprays or applications. A typical container 3, as disclosed in WO 96/06011 A1, holds e.g. a volume of about 2 to 10 ml.

The container 3 is substantially cylindrical or cartridge-shaped and once the nebulizer 1 has been opened the container can be inserted therein from below and changed if desired. It is preferably of rigid construction, the fluid 2 in particular being held in a collapsible bag 4 in the container 3.

The nebulizer 1 comprises preferably a pressure generator 5 for conveying and nebulizing the fluid 2, particularly in a preset and optionally adjustable dosage amount. The pressure generator 5 comprises preferably a holder 6 for the container 3, an associated drive spring 7, only partly shown, a releasing element 8 which can be manually operated to release the spring 7, a conveying element, such as a conveying tube 9, a non-return valve 10, a pressure chamber 11 and/or an nozzle 12 for nebulizing the fluid 2 into a mouthpiece 13. The container 3 is fixed or held in the nebulizer 1 via the holder 6 such that the conveying tube 9 penetrates into the container 3. The holder 6 may be constructed so that the container 3 can be exchanged.

As the drive spring 7 is axially tensioned the holder 6 with the container 3 and the conveying tube 9 is moved downwards in the drawings and fluid 2 is sucked out of the container 3 into the pressure chamber 11 of the pressure generator 5 through the non-return valve 10. Then, the nebulizer 1 is in the so called activated or tensioned state.

During the subsequent relaxation after actuation of the releasing element 8 the fluid 2 in the pressure chamber 11 is put under pressure as the conveying tube 9 with its now closed non-return valve 10 is moved back upwards by the relaxation of the drive spring 7 and now acts as a pressing ram or piston. This pressure forces the fluid 2 through the nozzle 12, whereupon it is nebulized into the aerosol 14, as shown in FIG. 1. The preferred droplet size of the particles has already been discussed above in the introductory part.

Generally, the nebulizer 1 operates with a spring pressure of 5 to 200 MPa, preferably 10 to 100 MPa on the fluid 2, with a volume of fluid 2 delivered per stroke of 10 to 50 μl, preferably 10 to 20 μl, most preferably about 15 μl. The fluid 2 is converted into or nebulized as aerosol 14 the droplets of which have an aerodynamic diameter of up to 20 μm, preferably 3 to 10 μm. Preferably, the generated jet spray has an angle of 20° to 160°, preferably 80° to 100°. These values also apply to the nebulizer 1 according to the teaching of the present invention as particularly preferred values.

A user (not shown) can inhale the aerosol 14, while an air supply can be sucked into the mouthpiece 13 through at least one air supply opening 15.

Preferably, the nebulizer 1 or drive spring 7 can be manually activated or tensioned. The nebulizer 1 comprises preferably an upper housing part 16 and an inner part 17 which is rotatable relative thereto (FIG. 2) having an upper part 17a and a lower part 17b (FIG. 1), while an in particular manually operable (lower) housing part 18 is releasable fixed, particularly fitted onto the inner part 17, preferably by means of a retaining element 19. Preferably, the housing parts 16 and 18 form a housing of the nebulizer 1. In order to insert and/or replace the container 3 the housing part 18 can be detached from the nebulizer 1 or its housing.

The housing part 18 can be rotated relative to the upper housing part 16, carrying with it the part 17b of the inner part 17. As a result the drive spring 7 is tensioned in the axial direction by means of a gear or transmission (not shown) acting on the holder 6. During tensioning the container 3 is moved axially downwards until the container 3 assumes an end position as shown in FIG. 2. In this activated or tensioned state the drive spring 7 is under tension. During the nebulizing process the container 3 is moved back into its original position (non-tensioned position or state shown in FIG. 1) by the drive spring 7. Thus the container 3 executes a lifting or stroke movement during the tensioning process and during the atomizing process.

The housing part 18 preferably forms a cap-like lower housing part and fits around or over a lower free end portion of the container 3. As the drive spring 7 is tensioned the container 3 moves with its end portion (further) into the housing part 18 or towards the end face thereof, while an aeration means, such as an axially acting spring 20 arranged in the housing part 18, comes in contact with base 21 of the container 3 and pierces the container 3 or a base seal thereon with a piercing element 22 when the container 3 makes contact with it for the first time, to allow air in or aeration.

The nebulizer 1 may comprise a monitoring device 23 which counts the actuations of the nebulizer 1, preferably by detecting the rotation of the inner part 17 relative to the upper part 16 of the housing. Preferably, the monitoring device 23 blocks the actuation or use of the nebulizer 1, e.g. blocks the actuation of the locking element 8, when a certain number of actuations or discharged doses has been reached or exceeded.

A preferred construction and mode of operation of a proposed inhaler or nebulizer 1 will now be described in more detail with reference to FIGS. 3 to 5, but emphasizing only essential differences from the nebulizer 1 according to FIGS. 1 and 2. The remarks relating to FIGS. 1 and 2 thus apply preferably accordingly or in a similar manner, while any desired combinations of features of the nebulizer 1 according to FIGS. 1 and 2 and the nebulizer 1 described below are possible.

Preferably, the container 3 is pre-installed. This can be realized in particular as shown in WO 2006/125577 A2 or as described in the following.

FIGS. 3 to 5 shows, in schematic sectional views, a nebulizer 1 according to a preferred embodiment of the present invention. FIG. 3 shows the nebulizer 1 in a delivery state, i.e. with pre-installed container 3 which is still closed. In this state, the housing of the nebulizer 1 is not completely closed, in particular the housing part 18 is not completely pushed on the inner part 17. FIGS. 4 and 5 show the nebulizer 1 in an activated state with the housing completely closed and with the container 3 opened. In FIG. 4, the nebulizer 1 or drive spring 7 is tensioned, i.e. the container 3 is in its lower position. FIG. 5 shows the nebulizer 1 in a non-tensioned state, e.g. after the delivery or discharge of one dose of the fluid 2, the container 3 is in its upper position.

The container 3 is already mounted or pre-installed in the nebulizer 1 in the delivery state, as shown in FIG. 3. In this state, the container 3 is still closed, i.e. there is no fluidic connection between the container 3 or its bag 4 on one hand and the nebulizer 1 or its pressure generator 5 or the conveying element on the other hand.

The container 3 comprises a fluid outlet 24 for outputting the fluid 2 to be dispensed. In particular, the fluid outlet 24 allows a fluidic connection between the container 3 or its bag 4 on one hand and the nebulizer 1, its pressure generator 5 or the conveying element on the other hand.

In the non-installed state of the container 3, i.e. before mounting or pre-installation of the container 3 in the nebulizer 1, the fluid outlet 24 is closed by a first or inner closure 25 and optionally by a second or outer closure 26. In particular, the second closure 26 covers the first closure 25.

The first or inner closure 25 is preferably formed by a septum, a membrane, a plastic seal or the like and/or is provided inside the container 3.

In the preferred embodiment, the second closure 26 is preferably formed by a seal, a foil, a cap or the like, in particular by a metallic and/or composite foil or the like, which is preferably hot-sealed or attached in any other suitable manner on or to a head end or axial end of the container 3. In the shown embodiment, the second closure 26 is formed preferably by a hot-sealed foil with an aluminum layer.

Preferably, the closures 25 and 26 are designed such that separate opening is possible, in particular such that the second closure 26 can be opened independently from the first closure 25 and/or has to be opened before the first closure 25.

Preferably, the closures 25 and 26 are designed such that successive opening is possible by means of one common element, in particular the conveying element or conveying tube 9 or the like, and/or by piercing.

In the preferred embodiment, the first closure 25 and second closure 26 are arranged one after the other and/or spaced in axial direction or direction of the stroke movement of the container 3 or with respect to the main outlet direction of the fluid 2.

Preferably, the first or inner closure 25 is formed or supported by a closure part 27 extending from the outlet or head end of the container 3 into the container 3 or bag 4. The second or outer closure 26 is preferably located adjacent to the head or axial end of the container 3 and/or held or connected to a flange 28, which can be formed by the closure part 27 or any other suitable part. However, other constructional solutions are possible.

In the delivery state according to FIG. 3, the container 3 has been pre-installed, i.e. inserted into the nebulizer 1. However, the container 3 or its fluid outlet 24 is not yet opened. In particular, the second closure 26 is already opened, but not the first closure 25. This is achieved in particular in that the housing of the nebulizer 1 is closed only partly, i.e. not completely, in the delivery state, preferably by not completely closing or pushing on the housing part 18 in the shown embodiment. Preferably, the housing part 18 is snapped on or inserted only partly in the delivery state.

Generally, the container 3, fluid outlet 24 or closures 25 or 26 are opened in particular by means of a conveying element, such as the conveying tube 9, or the like and/or by piercing or in any other suitable manner. In particular, the opening is achieved by moving the container 3 relative to the nebulizer 1 or conveying element or tube 9 or the like and/or by movement in longitudinal or axial direction.

According to the present invention, the second closure 26 is already opened in the delivery state, preferably automatically by the nebulizer 1. In particular, the second closure 26 is opened during or by or when inserting the container 3 and/or during, by or when—preferably partly—closing the housing or housing part 18 of the nebulizer 1. Preferably, the first closure 25 is designed such that, when the conveying element pierces or opens the first closure 25, such as a septum, any material may not fall into the fluid 2, but will stay connected to the closure part 27 or the like and/or will be pivoted aside.

In particular, the container 3 is attached to or held by or secured in the housing part 18, in particular by a transportation lock 29, which is preferably arranged within or at the housing part 18. The transportation lock 29 holds the container 3 preferably temporarily, in particular before attaching the housing part 18 to the nebulizer 1 and/or in the delivery state. In particular, the transportation lock 29 holds the container fixed during the fluidic connection of container 3 and/or during the mechanic of container 3, here with holder 6.

Preferably, the second closure 26 is automatically opened, in particular pierced, when pre-installing the container 3 and/or attaching the housing part 18 to the nebulizer 1, in particular when snapping or pushing the housing part 18 partly on the nebulizer 1. Then, the opening or piercing is effected in the preferred embodiment by the conveying element or conveying tube 9 which extends in the delivery state through the second closure 26 and in particular into the closure part 27, i.e. partly into the container 3. Thus, a very compact arrangement and a small size or axial extension of the nebulizer 1 can be achieved in the delivery state. In particular, the housing part 18 can be snapped or pushed on or inserted into the nebulizer 1 or its housing in the delivery state significantly further than in case of the prior art.

In the delivery state, the first closure 25 and, thus the container 3 and the fluid outlet 24 remain closed.

In the delivery state, the nebulizer 1 or the housing part 18 is preferably secured, in particular by means of a securing means or member 30, such that the container 3 and/or housing part 18 are held sufficiently spaced from the nebulizer 1 or upper housing part 16 and/or prevented from being completely inserted or pushed on the conveying element or tube 9, the housing or inner housing part 17 or the like and/or such that (complete) opening of the container 3, namely of the first closure 25, is prevented.

In the shown embodiment, the securing means or member 30 is preferably mounted between the housing part 18 and the upper housing part 16 and preferably engages with or between the housing parts 16 and 18, so that the housing part or lower part 18 is axially secured or is kept or held sufficiently away or spaced from the upper housing part 16 to be able to hold the (still) closed container 3 or first closure 25 away from the conveying tube 9.

In the preferred embodiment, the securing member 30 is at least substantially hollow and/or cylindrical and is disposed axially between the (lower) housing part 18 and the upper housing part 16. To activate the nebulizer 1 or prepare its for use, i.e. to push the housing part 18 fully on in the axial direction and thereby open the container 3, the securing member 30 first has to be removed or released or opened.

In the shown preferred embodiment, the securing member 30 is constructed in the manner of a banderole or the like, made of plastics, for example, and/or can be manually opened, removed or destroyed. The securing member 30 may alternatively or simultaneously form or constitute a seal of origin. However, other embodiments of the securing member 30 are also possible, e.g. in the form of a security tag or the like.

The securing member 30 can be made of any suitable material, in particular of plastics, any composite or the like. Further, the securing member 30 can be made of paper, in particular like a paper sleeve as shown in FIG. 6. Alternatively or additionally, the securing member 31 can be formed by a label, tap, tag or tape and/or be self-adhesive. In this case, also a sleeve can be formed as shown in FIG. 3.

Further, examples will be explained later.

Preferably, the container 3 and/or housing part 18 are held positively or in a form-fit or interlocking manner in the delivery state. This is achieved in the preferred embodiment in particular by means of the transportation lock 29 acting between the container 3 and the housing part 18, and the securing means or member 30 acting between the housing part 18 and the housing of the nebulizer 1 or the upper housing part 16 or the like. However, the transportation lock 29 or securing means or member 30 could also act directly between the container 3 on one hand and the nebulizer 1, its housing, the upper housing part 16, the inner housing part 17 or the holder 6 on the other hand.

The pre-installed container 3, i.e. its first closure 25, is still closed in the delivery state, i.e. non-activated state with pre-installed container 3. In this non-activated position, the housing part 18 is preferably secured so that it cannot be lost and, in particular, cannot be released. Then, the housing part or lower part 18 of the nebulizer 1 can no longer be detached from the nebulizer 1 after it has been (partially) axially pushed on for the first time, i.e. the nebulizer 1 cannot be opened any longer, with the result that that the container 3 cannot be changed, i.e. cannot be removed again.

In order to secure the housing part 18, it is preferably held or latched positively or in an interlocking or form-fit manner. Preferably, the housing part 18 is secured by latching means 43 particularly comprising at least one latching lug 31, protrusion, nose or the like which engages in an associated latching recess 32 in the housing part 18 or the like and, thereby, secures the housing part 18 against axial removal by interlocking engagement. In the present embodiment, the latching lug 31 may be formed by or at a latching arm 33 which can preferably flex. Thus, a ratchet-like—or vice versa—latching means 43 for securing the housing part 18 to the nebulizer 1 or to its housing or the upper housing part 16 is formed. However, other constructional solutions are also possible.

Once the securing member 30 has been removed a user (not shown) can push the housing part 18 fully on in the axial direction and thereby open the container 3, i.e. first closure 25, by inserting the conveying element or conveying tube 9. FIGS. 4 and 5 show this activated state with the housing part 18 pushed fully on and/or the container 3 open (fluidically connected to the nebulizer 1 or its pressure generator 5 or the conveying element or tube 9). In this pushed on or activated state, the housing part 18 is preferably secured or axially fixed again by interlocking engagement, i.e. form-fit manner in axial direction, particularly by further engagement of the latching means 43 or by means of some other mechanical securing device.

FIG. 4 shows the nebulizer 1 or container 3 in the activated state, the container 3, i.e. first closure 25, is open, i.e. the container 3 or its fluid 2 is fluidically connected to the nebulizer 1 or its pressure generator 5, and the housing part 18 has been pushed fully on in the axial direction. In order to bring the holder 6 into (complete) engagement with the container 3 at the head end and then be able to move the container 3 back and/or forth for the suction/tensioning and pressing strokes, it may be necessary to tension the nebulizer 1 or it drive spring 7 for the first time. During this tensioning process the holder 6 is moved together with the conveying tube 9 axially towards or into the housing part 18, thus bringing the holder 6 into (complete) engagement with the container 3 and preferably also moving or pressing the container 3 against the piercing element 22 in the region of the base of the housing part 18 and thereby piercing or opening a vent opening 34 in the container base 21. FIG. 4 shows the nebulizer 1 in this tensioned and activated state. The holder 6 is engaged with the container 3 and the conveying tube 9 has been fully inserted into the container 3.

FIG. 5 shows the nebulizer 1 in the relaxed, non-tensioned state, i.e. after atomization or discharge of a dose of the fluid 2. The holder 6 and the container 3 are in the upper position. The holder 6 is still engaged with the container 3 and remains engaged during the further uses of the nebulizer 1. Further, the container 3 is still open and fluidically connected, i.e. the nebulizer 1 remains activated.

In the delivery state shown in FIG. 3, i.e. with the container 3, namely the first closure 25, (still) closed, the nebulizer 1 can be shipped or delivered to the user. Then, the user can store the nebulizer 1 with the pre-installed container 3. The container 3 will be opened later before or during the first use of the nebulizer 1, namely when removing the securing member 30 and completely closing the nebulizer 1 or housing or housing part 18.

It should be noted that the opening of the container 3 is preferably carried out exclusively by mechanical means and/or manual actuation. However, it is additionally or alternatively possible to open it in other ways, e.g. by chemical, electrical, magnetic, pneumatic, hydraulic or similar means.

The proposed nebulizer 1 is activated after the removal of the securing member 30 and (total) axial pushing on of the housing part 18 and can be used in the same way as the nebulizer 1 shown in FIGS. 1 and 2. The pre-installation of the container 3 prevents the wrong container 3 or used containers 3 from being inserted in the nebulizer 1 by the user. Additionally it ensures that a separately supplied container 3 is not accidentally opened before being inserted in the nebulizer 1. Additionally the proposed solution prevents possible soiling or damage to the nebulizer 1, e.g. the conveying tube 9 or the like, when the nebulizer 1 is opened and the container 3 is used improperly.

As preferably the container 3 cannot then be removed, especially because the nebulizer 1 cannot be opened and the housing part 18 cannot be removed again, undesirable replacement of the container 3 by the user and in particular undesirable interim or subsequent opening of the nebulizer 1 by the user can be prevented.

To prevent unwanted opening of the container 3, particularly of the first closure 25, in the delivery state of the nebulizer 1, preferably the transportation lock 29 is provided. By frictional, forcible or interlocking engagement, for example, the transportation lock 29 prevents the container 3 from undesirably moving axially in the nebulizer 1, e.g. during transportation, in the event of accidental dropping of the nebulizer 1 or the like.

In the following, a preferred realization of the transportation lock 29 will be explained. It has to be noted that the transportation lock 29 can be realized independently from the preferred partial opening or piercing of the container 3 in the delivery state, in particular namely opening of the second closure 26. In particular, the proposed function and construction of the transportation lock 29 can be realized independently from the features of the present claims.

In the preferred embodiment, the transportation lock 29 comprises at least one gripping arm 35, preferably a plurality of gripping arms 35, for axially holding the container 3 in the delivery state, in particular by (radially) engaging around its preferably radially expanded base 21 or edge 36, as shown in FIG. 3.

The gripping arms 35 are preferably held or formed by or attached to or molded unitary with a member 37 which may form the bottom or base or end face of the housing part 18. Preferably, the member 37 or bottom holds the gripping arms 35 such that the arms 35 can flex or pivot.

Preferably, the piercing element 22 is also formed by or held by the member 37.

It has to be noted that the member 37 and/or the transportation lock 29 may be inserted into the housing part 18. The transportation lock 29 or part thereof can also be formed by or in the housing part 18.

Preferably, the transportation lock 29 is formed by multiple or only two different parts, here the gripping arm(s) 35 and a control member 39 as explained later.

The transportation lock 29, in particular, the gripping arms 35, are holding the container 3 in the delivery state (closed transportation lock 29) preferably such that the container base 21 or vent opening 34 are axially spaced from the piercing element 22, as shown in FIG. 3.

To open the transportation lock 29, the gripping arms 35 may be flexed radially outwardly. Preferably, the opening of the transportation lock 29 or the flexing of the gripping arms 35 occurs automatically when closing the nebulizer 1 or its housing completely, i.e. when snapping or pushing on the housing part 18 completely towards the upper housing part 16. During this (axial or telescopic) closing movement, the transportation lock 29 is opened and the container 3 released in axial direction preferably only in a last part of the movement and/or just little before the final completely closed position is reached or just when the final completely closed position is reached.

The closing movement of the nebulizer 1 opens the transportation lock 29 preferably automatically. In particular, the transportation lock 29 is opened by the direct or indirect interaction with or actuation by the housing of the nebulizer 1, the inner part 17 or its lower part 17b, a holding ring 38 bearing the spring 7 or the like. Preferably, the container 3 and/or first closure 25 are opened as well as the transportation lock 29 by means of a common actuation, here the closing movement of the nebulizer 1 or its housing or bottom part 18.

In the preferred embodiment, the transportation lock 29 comprises a control member 39, in particular a ring or the like, for actuating or opening or engaging with or pivoting preferably all gripping arms 35 simultaneously. In particular, the control member 39 or transportation lock 29 may convert a linear or axial movement into a pivot or radial movement of the gripping arms 35.

The control member 39 is shown in an upper position in FIG. 3 when the transportation lock 29 is closed. In this position, the control member 39 may secure the gripping arms 35 in the closed positions, in particular in a form-fit manner, e.g. by radially outwardly abutting portions (not shown) of the control member 39 or the like.

The control member 39 is axially moveable or shiftable in order to open the transportation lock 29. In particular, the control member 39 may be moved downwardly when completely closing the nebulizer 1 or its housing or completely pushing or snapping on the housing part 18. Preferably, the inner part 17 or ring 38 pushes the control member 39 downwardly or relatively to the gripping arms 35 so that the gripping arms 35 are released and, in particular, actively or positively opened or pivoted or flexed to open the transportation lock 29 and/or to release the container 3. In the shown embodiment, the control member 39 interacts with its axial end or an axial color or annular ring portion 40 with actuating portions 41 of the gripping arms 35 such that axially downward movement of the actuating portions 41 results in pivotation of the gripping arms 35 and radially outward flexing of the gripping arms 35. The flex characteristics of the gripping arms 35 depend on the used material, on the connection with member 37 and the like.

The control member 39 preferably opens the transportation lock 29 or gripping arms 35 positively.

FIGS. 4 and 5 show the transportation lock 29 and the gripping arms 35 in the open position, i.e. wherein the container 3 is free to move axially. In particular, control member 39 is shown in its downward end position. In this position, the control member 39 is preferably locked or secured within the bottom part 18, in particular by force-fit or form-fit or by a snap-connection, so that the transportation lock 29 and the gripping arms 35 are held open permanently.

However, other constructional solutions of the transportation lock 29 are possible. In this regard, reference is made in particular to WO 2006/125577 A2 which shows some other constructional solutions, which can be realized as well.

Preferably, in the non-activated state, i.e. when the housing part 18 has not been pushed on fully, the nebulizer 1 may be locked to prevent tensioning of the pressure generator 5, i.e. in particular to prevent rotation of the inner part 17 relative to the upper housing part 16. This may be important when the nebulizer 1 is supplied in the delivery state with the pressure generator 5 not under tension. Accordingly, the inhaler 1 may have a barrier, so that the inner part 17 can only be rotated relative to the upper housing part 16 when the housing part 18 has been pushed fully on. Alternatively or additionally, the securing member 30 may block not only pushing on of the bottom part 18 in the delivery state, but also any rotation of the inner part 17 until the securing member 30 has been opened, released or removed.

FIGS. 3 to 5 show the nebulizer 1 with a mouthpiece cover 42 covering the mouthpiece 13.

Generally, it should be pointed out that in the proposed nebulizer 1 the container 3 can preferably be inserted, i.e. incorporated in the nebulizer 1. Consequently, the container 3 is preferably a separate component. However, the container 3 may theoretically be formed directly by the nebulizer 1 or part of the nebulizer 1 or may otherwise be integrated in the nebulizer 1.

In the shown embodiment, the latching means 43 comprises multiple, here two latching lugs 31 engaging into associated latching recesses 32.

The latching arms 33 and/or latching lugs 31 are preferably formed at or by the inner part 17, in particular the lower part 17b. The latching recesses 32 are preferably formed at or by the housing part 18 which can be closed to cover the inserted container 3. However, the construction could also be vice versa or realized in any other suitable manner.

In the shown embodiment, the latching means 43 or housing part 18 comprises a first undercut or shoulder 44 associated to the respective latching recess 32 so that the engaging or abutting latching lug 31 holds the housing part 18 in a non-detachable or inseparable manner in the delivery state as shown in FIG. 3. This forms a first form-fit engagement or holding.

The latching means 43 forms or enables preferably a second form-fit engagement or holding of the housing part 18 in the activated state. This is realized in the shown embodiment in that the latching lugs 31 engage into further latching recesses 45 and/or behind second undercuts or shoulders 46 as shown in FIGS. 4 and 5. The second engagement of the latching means 43 is achieved preferably by completely closing the housing or housing part 18 of the nebulizer 1.

It has to be noted that the latching means 43 can be realized e.g. with only one latching lug 31, protrusion, nose, locking element or the like if desired. In this case, the above description applies preferably as well or in a similar manner.

According to a preferred aspect, the housing part 18 may be pre-mounted to the nebulizer 1, its housing or to the inner part 17 without container 3 so that the nebulizer 1, its housing or the housing part 18 can be opened again, i.e. so that the latching means 43 does not prevent opening, for later inserting or pre-installing the container 3, in particular at another factory or at a pharmacy or the like. This pre-mounting of the housing part 18 is preferably achieved in that the housing part 18 is mounted in another position, preferably another rotational position, on the nebulizer 1, in particular the inner part 17 of lower part 17b.

FIG. 6 shows in a schematic sectional view the nebulizer 1 with the pre-mounted housing part 18. Due to the other (rotational) position of the housing part 18 relative to the inner part 17, each latching lug 31 engages into a different or additional recess, groove 47 or the like. In the shown embodiment, the grooves 47 are formed in the housing part 18. The grooves 47 are axially open so that the associated latching lugs 31 may be axially drawn out of the grooves 47. Thus, the latching means 43 do not provide any latching or form-fit holding or the like in the pre-mounted state of the housing part 18. Nevertheless, the preferably radially flexible and/or biased latching lugs 31 or the latching means 43 may hold the housing part 18 by friction or force-fit so that unintentionally losing of the housing part 18 can be prevented.

FIG. 7 shows the nebulizer 1 in a schematic, explosion-like view. The following parts are separated in this view: the mouthpiece cover 42, the housing comprising upper housing part 16 and inner part 17, the securing member 30, the control member 39, the housing part 18, the container 3, and the base member 37 of the housing part 18.

FIG. 7 shows that the at least one latching lug 31 and its associated latching arm 33 may be formed for example in a through hole 48 of the inner part 17/lower part 17b. This through hole 48, in particular multiple through holes 48, may be used for engagement of holding portions of the ring 38.

The housing part 18 and the housing or inner part 17/17b of the nebulizer 1 are adapted to each other such that the housing part 18 can be pushed onto the part 17/17b in two different rotational positions, in the present embodiment in two positions offset by 180°. For this purpose, the housing part 18 may have at least one indention 48 or any other deformation or non-circular inner cross-section, in the shown embodiment it has two indentions 49 on opposite sites, corresponding or cooperating with a respective complementary form, in the shown embodiment with the monitoring device 23 of the inner part 17/lower part 17b. However, other constructional solutions are possible.

The at least one latching lug 31 on one hand and the at least one latching recess 32 and the at least one groove 47 on the other hand are distributed over the circumference such that the at least one latching lug 31 engages only into the respective groove 47 in the pre-mounted state of the housing part 18 and into the respective latching recess 32/45 in the other/rotational state (delivery state or activate state), i.e. in the usual mounting position, of the housing part 18. Preferably, the two latching lugs 31 are not positioned directly opposite to each other on the circumference of part 17/17b, but offset. Accordingly, the schematic sections according to FIGS. 3 to 6 are not in one flat plane, but along a plane folded along the longitudinal or rotational axis or the conveying tube 9.

For assembly and pre-installing the container 3, the securing member 30 is mounted onto inner part 17/lower part 17b and, the housing part 18 including the pre-installed container 3 (the container 3 is held within the housing part 18 by the closed transportation lock 29) is pushed onto inner part 17/lower part 17b, in particular until the securing member 30 is reached and/or the first engagement of the latching means 43 is reached. Thus, the housing part 18 is connected to the nebulizer 1 or its housing or to the inner part 17 or housing part 16 in a non-detachable manner. With other words, the nebulizer 1 can not be opened any more, the container 3 can not be removed or replaced any more.

The securing member 30 can be manually opened, removed, released or destroyed to allow complete closing of the housing or nebulizer 1, i.e. to push the housing part 18 completely on the inner part 17, to reach the activated state, i.e. to allow fluidic connection or opening of the container 3.

Preferably, the securing member 30 comprises an actuator 50 to open, remove, release or destroy the securing member 30. The actuator 50 is preferably non-detachable from the securing member 30. Preferably, the securing member 30 is made as one piece, in particular integrally with the actuator 50.

Preferably, the securing member 30 is made of plastics. However, the securing member 30 can be made of any other suitable material or from different materials. In particular, the securing member 30 is molded.

The securing member 30 comprises preferably a body 51. The securing member 30 or body 51 is preferably hollow and/or preferably forms a sleeve, ring, loop, banderole, or the like. In particular, it forms a closed sleeve or ring.

In the shown embodiment, the actuator 50 may form part of the circumferential wall, ring or sleeve formed by the body 51.

The actuator 50 is preferably inseparable from the securing member 30 or body 51 even if the securing member 30 is opened, removed, released or destroyed to allow fluidic connection opening of the container 3 and/or to allow entering of the activated state.

The securing member 30 or body 51 preferably comprises engagement means, such as at least one stop 52, protruding radially inwardly and/or engaging between the housing part 18 on one hand and the nebulizer 1, its housing, the upper housing part 16 or the ring 38 on the other hand, in particular to form an axial stop or abutment for the housing part 18 in the delivery state against movement into the activated state. In the present embodiment, the engagement means are preferably formed by ribs or protrusions extending in particular axially and protruding radially inwardly. Preferably, the engagement means are and/or covered and/or formed by the body 51. However, other constructional solutions are possible as well.

In the following, the term “to open the securing member” or similar formulations shall include that the securing member 30 is removed, release, destroyed or the like.

To open the securing member 30, a user (not shown) pulls, tears, pivots, tilts, pushes, presses and/or removes the actuator 50. For this purpose, the actuator 50 may form or may be formed by a handhold 53, grip, lever, tag, flap, ring, clip or the like as shown in some examples in the further figures.

The securing member 30 or body 51 comprises preferably at least one pre-determined breaking line 54 in order to facilitate opening and/or to ensure a defined opening. For example, the breaking line 53 may extend along and/or adjacent to the actuator 50 and/or on both or opposite sides of the actuator 50.

The breaking line 54 can be defined or pre-formed in particular by respective thinning of the material, a respective perforation or the like, in particular of the body 51.

In the shown embodiment, the breaking line 54 extends at least essentially in axial direction (the term “axial direction” means generally at least essentially parallel to the longitudinal or central axis or rotational axis of the nebulizer 1 and/or to the main dispensing direction of the aerosol 14/nebulizer 1).

Preferably, the securing member 30 locks the housing part 18 against rotation. This can be achieved in that the securing member 30 engages with the nebulizer 1 or upper housing part 16 and with the lower housing part 18 respectively in a form-fit manner, e.g. by axial engagement and/or by at least partially covering the preferably non-circular outer contour of the respective parts 16/18. However, other constructional solutions are possible as well.

After pulling the actuator 50, the securing member 30 or body 51 is open, preferably along at least one breaking line 54, so that the closed ring, sleeve or banderole of the securing member 30/body 51 is open and can be detached from the nebulizer 1 in particular by respective moving or flexing the free ends of the body 51 away from each other. Thus, the securing member 30 can be detached from the nebulizer 1. This allows to push the housing part 18 onto the inner part 17, i.e. towards the upper housing part 16, so that the container 3 is fluidically opened or connected and the housing of the nebulizer 1 is completely closed.

It has to be noted that the securing means 30 or the body 51 is preferably sufficiently flexible such when the actuator 50 has been pulled and the securing means 30 has been opened, the body 51 can be detached from the nebulizer 1.

In the present embodiment, the actuator 50 is directed to or points towards the housing part 18 and/or away from the mouthpiece 13 and/or essentially in axial direction.

In the following, further embodiments of the securing member 30 are explained with reference to the further figures, wherein only mayor differences are discussed or emphasized. The previous explanations and description of the previous embodiment and of the further embodiments apply preferably in addition or in a similar manner, even if not repeated.

FIG. 8A shows a side view (front face) of the nebulizer 1 with another securing member 30 and FIG. 8B shows it in a view of a transversal side (side face). In this embodiment, the actuator 50 extends upwards so that the handhold 53 extends at least in front of the mouthpiece cover 42 covering the releasing element 8. Preferably, the actuator 50 or its handhold 53 engages with the mouthpiece cover 42 or covers the mouthpiece cover 42 partially or engages therewith such that the actuator 50/handhold 53 has to be pulled (as schematically indicated in FIG. 8b by an arrow) before the mouthpiece cover 42 can be opened. This facilitates an intuitive handling of the nebulizer 1.

The actuator 50 extends essentially in axial direction and/or towards the dispensing and/or mouthpiece 13 of the nebulizer 1.

The securing means 30 comprises in this embodiment preferably only one breaking line 54.

The breaking line 54 is essentially continuously curved and, for example, at least from an essentially axial extension at the upper circumference of the body 51 to an at least essentially circumferential direction at the lower circumference of the body 51.

The actuator 50 comprises preferably a portion 55 connecting the handhold 53, grip, lever, tag, flap, ring, clip or the like with the body 51. This portion 55 is preferably stem-like and/or flexible.

FIG. 9A shows a side view (front face) of the nebulizer 1 with another securing member 30 and FIG. 9B shows it in a view of a transversal side (side face). This embodiment differs from the embodiment according to FIG. 8 essentially in that the actuator 50 or its handhold 53 extends below the part of the mouthpiece cover 42 which covers the releasing element 8. Thus, the mouthpiece cover 42 has to be opened first before the actuator 50 or its handhold 53 can be actuated, in particular grabbed or pulled. This allows also an intuitive handling. Namely, the actuator 50 or its handhold 53 is located at least partially above or on the releasing element 8 so that the user will usually actuate the actuator 50 before pressing the releasing element 8.

In this embodiment, the breaking line 55 extends more or less helically around the body 51.

FIG. 10A shows a side view (front face) of the nebulizer 1 with another securing member 30 and FIG. 10B shows it in a view of a transversal side (side face). In this embodiment, the actuator 50 is located on another side than the releasing element 8 (which is not visible because it is covered by the mouthpiece cover 42). In particular, the actuator 50 or its handhold 53 is located on a transversal side or side face relative to the side (front face) with the operating button, i.e. releasing element 8, of the nebulizer 1.

In this embodiment, the breaking line 54 runs at least essentially in axial direction.

FIG. 11A shows a side view (front face) of the nebulizer 1 with another securing member 30 and FIG. 11B shows it in a view of a transversal side (side face). This embodiment is very similar to the embodiment according to FIG. 9. Here, the nebulizer 1 is shown with open mouthpiece cover 42. Further, the handhold 53 is formed slightly differently. A half-circular form is closed by a substantial horizontal connection. In the embodiment according FIG. 9, the handhold 53 has an essentially half-circular or U-form, but does not form a closed loop or ring-like structure as shown in the embodiments according to FIGS. 8 and 11.

FIG. 12A shows a side view (front face) of the nebulizer 1 with another securing member 30 and FIG. 12B shows it in a view of a transversal side (side face). In this embodiment, the actuator 50 is located at a side face of the nebulizer 1, similar to the embodiment according to FIG. 10. Further, the actuator 50 or its portion 55 is curved and extends more or less from the front face with the releasing element 8 (shown in FIG. 12A) to the side face (shown in FIG. 12B).

In this embodiment, the actuator 50 is at essentially strip-like and/or broadens towards its free end.

Further, the actuator 50 continues essentially the curvature of the breaking line 54. The actuator 50 or its portion 55 and the breaking line 54 extend essentially along a half circle.

The opening of the securing member 30 or actuator 50 is schematically indicated by the arrow shown in FIG. 12B.

FIG. 13A shows a side view (front face) of the nebulizer 1 with another securing member 30 and FIG. 13B shows it in a view of a transversal side (side face). This embodiment is similar to the embodiment according to FIG. 12. In the present embodiment, the actuator 50 is differently curved and is at least essentially tapered or narrowed to its free end. Here, the actuator 50 or its portion 54 and the breaking line 53 form a soft curve or part of a helical line.

FIG. 14A shows a side view (front face) of the nebulizer 1 with another securing member 30 and FIG. 14B shows it in a view of a transversal side (side face). FIG. 14C shows a horizontal section of the securing member 30 without the nebulizer 1. In this embodiment, the actuator 50 is connected via a living hinge 56 (shown in FIGS. 14A and 14B at the lower end of the body 51) and is tilted upwards so that it passes or extends within the body 51 and extends towards the mouthpiece 13 and/or in axial direction. The actuator 50 is located at the side face of the nebulizer 1. To open the securing member 30, the actuator 50 is tilted or pivoted radially outwardly around the living hinge 56 wherein the portion 55 opens the body 51. For this purpose, the actuator 50 or portion 55 preferably forms a rib or cutting edge 57 as schematically shown in the section according to FIG. 14B.

The body 51 is formed preferably in one piece. The body 51 can comprise or form two parts or halves 51a and 51b which can be connected via a pivotal joint or hinge 51c, such as a living hinge. In this case, the parts or halves 51a and 51b may be relatively stiff or rigid. To open the body 51, the two parts or halves 51a and 51b are pivoted away from each other around the hinge 51c. This is possible after actuating the actuator 50, in particular after opening or breaking the body 51 along the breaking line 54.

It has to be noted that the concept of two parts or halves 51a and 51b connected by a pivotal connection or hinge 51c can be used in any other embodiment as well. Further, the two parts or halves 51a and 51b may be formed as separate parts and connected via any other type of joint or hinge 51c.

It has to be noted that the body 51 forms or comprises preferably an at least essentially closed and/or smooth surface over the circumference. However, other designs and constructions are possible as well.

FIG. 15A shows a side view (front face) of the nebulizer 1 with another securing member 30 and FIG. 15B shows it in a view of a transversal side (side face). Here, the actuator 50 has to be actuated more or less in a tangential direction perpendicular to the axial direction. In the previous embodiments, the actuator 50 has to be actuated at least essentially radially outwardly, in particular by radial pulling, which can be combined with a downward movement or downward pivotation and/or with a circumferential movement.

In the present embodiment, the actuator 50 acts as a lever which is supported on one circumferential side in the upper region of the body 51 by a firs connection or bearing 58 and on the other circumferential side in a lower region of the body 51 by a second connection or bearing 59. The connections or bearings 58, 59 are axially offset. When the actuator 50 is operated or tilted, the adjacent parts of the body 51 are moved away from each other. Thus, the diameter of the body 51 is increased and the securing member 30 can be disengaged and moved over the housing part 18 in order to detach the securing member 30 from the nebulizer 1.

FIG. 16A shows a side view (front face) of the nebulizer 1 with another securing member 30 and FIG. 16B shows it in a view of a transversal side (side face). In this embodiment, the actuator 50 is formed by the body 51 or part of the body 51. In particular, the actuator 50 does not comprise a handhold 53 or the like and/or a portion 55 extending or protruding from the body 51. The handhold 53 is preferably formed by a portion of the body 51 forming a flap or end-part, preferably adjacent to the breaking line 54. This end portion can be grabbed manually to open the securing member 30 or its body 51. Alternatively and preferably the securing member 30 or its body 51 is opened—in particularly along the breaking line 54—by turning the housing part 18 relative to the nebulizer 1/upper housing part 16. In this case, the securing member 30 or its body 51 is opened by torsioning. In order to allow turning of the housing part 18, it may be necessary to allow that inner part 17 can be turned relative to the nebulizer 1 or upper housing part 16. However, the nebulizer 1 could be respectively adapted also in a different manner. The turning of the housing part 18 to open the securing member 30 or body 51 is schematically indicated in FIG. 16 by arrows.

The breaking line 54 extends preferably at least essentially along a helical line of the body 51. However, the breaking line 54 can follow other courses or paths.

FIG. 17A shows a side view (front face) of the nebulizer 1 with another securing member 30 and FIG. 17B shows it in a view of a transversal side (side face). In this embodiment, the actuator 50 is formed by or integrated into the body 51 similar as in the embodiment according to FIG. 16. In particular, the actuator 50 does not comprise a handhold 53 and/or portion 55 extending or protruding from the body 51, in particular in axial direction. In the present embodiment, the actuator 50 extends at least essentially in circumferential direction and/or around or along the body 51. Preferably, the actuator 50 or its handhold 53 forms, comprises or is formed by a flap, a hanger, a clip, a strap or an ear as schematically shown in FIG. 17.

In the present embodiment, the actuator 50 or its handhold 53 is pulled at least essentially in circumferential or tangential direction and/or around the body 51 to open the securing member 30.

The securing member 30 comprises one or two breaking lines 54 extending at least essentially along a circumference of the body 51 with axially curved or ends or start portions 54A.

FIG. 18A shows a side view (front face) of the nebulizer 1 with another securing member 30 and FIG. 18B shows it in a view of a transversal side (side face). In this embodiment, the securing member 30 or body 51 does not comprise or form an initially closed loop, banderole, ring or sleeve (between the housing parts 16 and 18) as in the previous embodiments. Instead, the body 51 is closed by means of connecting means 60, such as a rivet or pin connection as indicated in FIG. 18. In particular, the connecting means 60 connects overlapping part or ends of the body 51 and/or provides a releasable connection to allow opening of the body 51 and detachment of the securing member 30.

The actuator 50 is located at the side face of the nebulizer 1. The handhold 53 is ring-like preferably similar to the one shown in the embodiment according to FIG. 14. To open the securing member 30 or body 51, the actuator 50 or its handhold 53 has to be pulled radially outwards, downwards and/or sidewards as schematically indicated by an arrow in FIG. 18B. Thus, the connecting means 60 is opened or released.

FIG. 19A shows a side view (front face) of the nebulizer 1 with another securing member 30 and FIG. 19B shows it in a view of a transversal side (side face). The securing member 30 or body 51 comprises connecting means 60 similar to the embodiment according to FIG. 18.

FIG. 24A shows a side view (front face) of the nebulizer 1 with another securing member 30 and FIG. 24B shows it in a view of a transversal side (side face). In the present embodiment, the securing member 30 is not a single piece, but consists of multiple or at least two parts, in particular in contrast to the previous embodiments. In the present embodiment and in the embodiments shown in FIGS. 25 and 26, the actuator 50 is not formed in one piece or integrally with the body 51, but made as a piece separate from body 51.

In the embodiment according to FIG. 24, the actuator 50 comprises a through hole or recess 64, into which the free ends of the body 51 are inserted. The free ends can be bent, folded or thickened so that the actuator 50 is held by or connected to the body 51 by force-fit or form-fit. When the actuator 50 is tilted, pivoted or pulled, in particular as indicated by the arrow shown in FIG. 24A, the actuator 50 is drawn from the free ends of the body 50 and, thus, detached from the body 51. Then, the body 51 is open and can be detached from the nebulizer 1.

In the shown embodiment, the actuator 50 is designed and/or located similar as in case of the embodiment according to FIG. 14. In particular, it extends in axial direction and/or is located on the side face. Alternatively or additionally, the body 51 may be formed by two parts or halves 51a and 51b which may be pivoted relatively to each other to open the body 51 as described in particular in connection with FIG. 14C.

FIG. 25A shows a side view (front face) of the nebulizer 1 with another securing member 30 and FIG. 25B shows it in a view of a transversal side (side face). This embodiment is very similar to the embodiment according to FIG. 24. However, the actuator 50 is axially clipped or radially pushed onto the free ends of the body 51 and/or holds the free ends of the body 51 together like a clamp in the embodiment according to FIG. 25. The actuator 50 can be opened or detached preferably by radial pulling and/or axial pushing.

FIG. 26A shows a side view (front face) of the nebulizer 1 with another securing member 30 and FIG. 26B shows it in a view of a transversal side (side face). This embodiment is very similar to the embodiment according to FIG. 25. However, the actuator 50 forms a circumferential clamp closing or holding the body 51 together. To open the securing member 30 or body 51, the actuator 50 is pulled radially outwards and/or shifted, in particular in circumferential direction or in any other suitable direction and thus released or detached.

FIG. 27A shows a side view (front face) of the nebulizer 1 with another securing member 30 and FIG. 27B shows it in a view of a transversal side (side face). This embodiment, the actuator 50 is made from a different material than the body 51 in contrast to the previous embodiments. Preferably, the actuator 50 is formed by a preferably self-adhesive tap 66, tag, label or tape and/or made of any other suitable, preferably flexible or foil-like material. The actuator 50 extends preferably in circumferential direction and closes the body 50, in particular by adhering the actuator 50 over a radial gap or slit 65 of the body 50. To open the securing member 30 or body 51, the actuator 50 is broken, torn or drawn from the body 51. Then, the body 51 can be detached from the nebulizer 1.

FIG. 28A shows a side view (front face) of the nebulizer 1 with another securing member 30 and FIG. 28B shows it in a view of a transversal side (side face). This embodiment is very similar to the embodiment according to FIG. 27. In this embodiment, the actuator 50 is larger, in particular in axial direction, than the body 51 and/or the actuator 50 of FIG. 27. Further, the securing member 30, body 51 or the actuator 50 may comprise or support or form a tap 66 which may be self-adhesive or adhered to any part thereof and/or which may at least partly cover any part thereof, such as the actuator 50 or its portion 55.

It has to be noted in general that the securing member 30 or actuator 50 or its portion 55 can be provided with symbols 67, in particular such as numerals, letters, colors, codes, signs and/or instructions or the like, in particular relating to the handling or opening and/or relating to the nebulizer 1, its medicament or fluid 2 or the like. This can be realized by using a respective, preferably self-adhering plate, tag 66 or tap or the like which could be used in addition to the actuator 50 or form the actuator 50 or any other part of the securing member 30. Alternatively or additionally, such symbols, signs, instructions or the like can be formed by molding, printing or the like, in particular on any suitable surface of any component of the securing member 30.

As already mentioned, individual features, aspects and/or principles of the embodiments described may also be combined with one another as desired and may be used particularly in the known nebulizer 1 according to FIGS. 1 and 2 but also in similar or different nebulizers.

Unlike freestanding equipment or the like the proposed nebulizer 1 is preferably designed to be portable and in particular is a mobile hand operated device.

The proposed solution may, however, be used not only in the nebulizers 1 specifically described here but also in other nebulizers or inhalers, e.g. powder inhalers or so-called metered dose inhalers.

Preferably, the fluid 2 is a liquid, as already mentioned, especially an aqueous pharmaceutical formulation. However, it may also be some other pharmaceutical formulation, a suspension or the like.

According to an alternative embodiment the fluid 2 may also comprise particles or powder. In this case, instead of the expulsion nozzle 12, some other kind of supply device may be provided, especially an expulsion opening (not shown) or a supply channel (not shown) for supplying the fluid to or powder or the like into the mouthpiece 13. The optional air supply opening 15 then serves to supply ambient air preferably in parallel so as to general or allow an airflow with a sufficient volume for breathing in or inhaling through the mouthpiece 13.

If necessary the fluid 2 may also be atomized by means of a propellant gas.

Preferred ingredients and/or formulations of the preferably medicinal fluid 2 are listed in particular in WO 2009/047173 A2 which is incorporated herewith by reference. As already stated, these may be aqueous or non-aqueous solutions, mixtures, formulations containing ethanol or free from solvent, or the like.

In the following, a further, preferred embodiment of the inhaler or nebulizer 1 according to the present invention will be described in detail with reference to FIGS. 29 to 32 wherein only essential differences will be emphasized so that the previous remarks and explications preferably in a corresponding or similar manner. This nebulizer 1 comprises in the delivery state a pre-installed container and the securing member 130 as already described. Although, it is not shown in the following drawings.

FIG. 29 shows in a very schematic, partially sectional view the nebulizer 1. The nebulizer 1 is shown a transitional state from the delivery state to the activated state with not completely closed housing or housing part 18. The housing part 18 has already been pushed on the inner part 17 more than initially provided in the delivery state such as shown in FIG. 3. Therefore, the container 3 has already been opened in the state shown in FIG. 29. Further, the securing member 30, which preferably secures the housing part 18 in the delivery state against pushing on the inner part 17, has already been released or opened or removed in the state shown in FIG. 29.

The nebulizer 1 or its housing comprises a securing means 135 for holding the container 3 such that the container 3 is moveable back and forth for the conveying of the fluid 2, pressure generation and/or nebulization, but is inseparable from the housing or housing part 18, and/or such that the container 3 is unmoveably held in the delivery state of the nebulizer 1.

The securing means 135 is located or arranged preferably at or in the housing part 18 as shown in FIG. 29.

FIG. 30 shows in a perspective view a preferred embodiment of the securing means 135. FIG. 31 shows the securing means 135 connected with the container 3.

Preferably, the securing means 135 comprises or consists of a metal and/or stamping part and/or consists of a single, unitary part as shown in FIG. 30.

Preferably, the securing means 135 is made of steel, in particular spring steel.

Preferably, the securing means 135 is produced from sheet material by cutting, stamping or the like and/or by bending.

Preferably, the securing means 135 or the part forms a cage, in particular, encompasses the container 3 or an end portion thereof.

Preferably, the securing means 135 comprises holding elements 136 and/or locking elements 37. The elements 136 and 37 are preferably designed like arms, fingers leaves or the like. In particular, the elements 136, 37 are alternately distributed over a circumference of the container 3 and/or extend at least essentially axially or in the direction of the back and forth movement of the container 3.

Preferably, the elements 136 and 37 are held by or connected with a base 138 of the securing means 135.

Preferably, the securing means 135 or base 138 comprises or holds the piercing element 22 for piercing the container 3, i.e. opening the container base 21 or its venting hole 134 in the activated and tensioned state, i.e. when the container 3 reaches its lower end position. In the shown embodiment, the piercing element 22 is formed by a respective bending of a spring portion 139 of the securing means 135 or its base 138. The spring portion 139 can support or facilitate the (complete or final) connection of the container 3 to holder 6.

The securing means 135 or base 138 comprises preferably at least one or multiple fixing portions 140 for fixing the securing means 135 at or in the nebulizer 1 or housing or housing part 18. In particular, the fixing portions 140 may fix the securing means 135 when the securing means 135 is pressed into the housing part 18 by cooperating with the side wall of the housing part 18. However, it is also possible to overmold the securing means 135, its base 138, the fixing portions 140 or the like. Moreover, the securing means 135 could be connected with the housing part 18 or the like in any other suitable manner. Preferably, the securing means 135 does not only prevent the separation of the container 3 from the nebulizer 1, its housing or housing part 18, but also forms the transportation lock 129 for holding the container 3 unmovable in the housing in the delivery state of the nebulizer 1. FIGS. 29 and 31 shows this state or situation when the container 3 is held (axially) unmovable by the securing means 135, i.e. when the transportation lock 129 is closed. In this situation, the container 3 or its preferably radially protruding end or edge 141 of the container 3 is held between the holding element 136 and locking element 37, in particular between respectively formed or bent ends of the elements 136 and 37.

In the shown embodiment, the container end or edge 141 is caught between end portions 136a and 37a of the elements 136 and 37. The holding elements 136 grip or extend over the edge 141 and the locking elements 37 or its end portions 37a grip or extend under the edge 141 or container base 21 so that the edge 141 and container 3 are securely held preventing any axial movement of the container 3 relative to the securing means 135 and relative to the associated housing part 18 in this state, i.e. with locked securing means 135/transportation lock 129.

The holding element 136 and the locking elements 137 are distributed alternatingly around the container 3 or edge 141.

Preferably, the end portions 136a of the holding elements 136 end in a first radial plane and the end portions 137a of the locking elements 137 end in another, second radial plane, wherein the two planes are axially offset to hold the edge 141 in between and/or wherein the second plane is located axially between the first plane and the lower end position of the container 3 or the lower end of the housing part 18 or the piercing element 22. Additionally or alternatively, the end portions 136a end on another radius (outer radius) than the end portions 137a and/or are axially spaced therefrom.

The end portions 136a and/or 137a are preferably form like claws or the like and/or extend preferably radially inwardly.

Preferably, the elements 136 and/or 137 can flex with its free ends radially outwardly.

For example, the ends of the end portions 136a may be inclined such that the container 3 may be inserted into or connected with the securing means 135 by a respective axial force so that the holding elements 136 flex outwardly to allow passing of edge 141. However, the holding elements 136 can be flexed outwardly also by a suitable tool (not shown) or the like when the container 3 is inserted, in particular with its edge 141, into the securing means 135.

Preferably, the holding elements 136 prevent separation of the container 3 from the securing means 135 and, thus, from the associated housing part 18 or the like.

The locking elements 137 or its end portions 137a can be flexed radially outwardly in order to open the axial holding or transportation lock 129 (this will be explained in detail with reference to FIG. 32 in the following). Then, the container 3 can axially move, in particular back and forth and/or with its edge 141 between the first plane and the piercing element 22 in the present embodiment.

In the present embodiment, the locking elements 137 comprise actuation portions 137b (preferably formed at the free ends and/or between adjacent end portions 137a). Preferably, the actuation portions 137b form axial extensions which may be radially offset. The actuation portion 137b cooperate with an associated control member 142 or multiple control members 142 of the nebulizer 1 such that the locking elements 137 are flexed radially outwardly when (completely) closing the housing to open the transportation lock 129 (here primarily formed by the locking elements 137 or its end portions 137a).

FIG. 29 shows schematically the control member 142 axially spaced from the associated actuation portion 137b as the housing has not yet been closed (completely).

FIG. 32 shows a lower part of the completely closed nebulizer 1 with opened transportation lock 129, i.e. with radially outwardly flexed locking elements 137. FIG. 32 shows that the control member 142 has an inclined guiding surface or the like to convert the axial closing movement into the radial opening movement of the actuation portion 137b and, thus, of the associated locking element 137 to open the transportation lock 129, in particular when the house ing has been completely closed or when the housing part 18 has been pushed completely on the nebulizer 1.

The control member 142 is preferably formed as an axial protrusion. It can be formed by or at a ring 143 or any other bearing means of the nebulizer 1 for counter-bearing the drive spring 7 in the inner part 17 or by or at any other suitable component if the nebulizer such as the inner part 17.

The control member 142 may be formed like an axial protruding ring or shoulder or ridge which extends along the ring 143.

The control member 142 may additionally secure the holding elements 136 against axial opening when the housing is completely closed as schematically shown in FIG. 32. In this case, the control member 142 contacts the holding element(s) 136 or its end portions 136a peripherally on the outer side to prevent any outward flexing. Then, the securing means 135 or its holding elements 136 are secured against opening so that the container 3 is securely held within the securing means 135 or the cage formed by the securing means 135 or holding elements 136.

FIG. 32 shows the container 3 in its lower position when the piercing element 22 can pierce the venting hole 134 or an associated seal attached to the container base 21.

In the present embodiment, the securing means 135 has multiple functions. It holds the container 3 (in the activated state/with completely closed housing) such that it can move back and forth, in particular during conveying of the fluid 2, during pressure generation and/or during nebulization, wherein the container 3 is inseparable from the housing or the housing part 18. Further, the securing means 135 forms the transportation lock 129 and/or holds the container 3 unmovable in the delivery state of the nebulizer 1. Additionally or alternatively, the securing means 135 comprises an opening means, here the piercing element 22, for opening the venting hole 134 of the container 3.

Preferably, the securing means 135 forms a cage which cannot be separated from the container 3 after connecting it with the container 3.

The transportation lock 129 and the locking elements 137 are kept opened during the normal use of the nebulizer 1, in particular as long as the housing is (completely) closed. When the housing is opened, i.e. the housing part 18 is detached, the control member 142 may disengage from the actuation portions 137b so that the locking element 137 can close or flex inwardly again. Then, the locking elements 137 may grip with its end portions 137a over the edge 141 of the container 3 such that an additional lock is formed which prevents that the container 3 can be separated from the securing means 135/housing part 18.

The securing means 135 prevents separation of the container 3 from the housing part 18. Therefore, the container 3 can be replaced or exchanged only together with the housing part 18 if the housing part 18 can be detached from the nebulizer 1 or inner part 17 at all. However, it is also possible that the nebulizer 1 can not be opened. Then, the container 3 can not be replaced.
