Abstract

A dispensing head for a dispenser for dispensing a fluid is proposed wherein the dispensing head comprises a housing portion and an actuator which is rotatable relative to the housing portion to actuate the dispensing head or dispenser, and wherein the dispensing head, in particular the housing portion, comprises a tamper-evident seal. According to a first aspect, the actuator and the tamper-evident seal are configured such that when the actuator is first rotated relative to the housing portion from a first rotational position to a second rotational position, the actuator exerts a force on the tamper-evident seal, in particular in the direction of rotation of the actuator and / or radially outward, and the actuator exerts a force on the tamper-evident seal, in particular in the direction of rotation of the actuator and / or radially outward. In this way, the tamper-evident seal is damaged and / or folded down. According to a second aspect, the tamper-evident seal is formed integrally with the housing portion.

Description

Technical Field

[0001] The invention relates to a dispensing head for dispensing a fluid according to the preamble of claim 1 and to a dispenser for dispensing a fluid comprising the dispensing head.

[0002] In particular, the present invention relates to a dispensing head of a dispenser for dispensing a fluid, the dispensing head having a tamper-evident seal. The fluid is preferably a cleaning product or a cosmetic, such as a bathroom or glass cleaner, shower gel, shampoo, cream, perfume, or the like. Background Art

[0003] In principle, it is also known in the prior art, in particular in the food and cosmetics field, to provide products with packages or containers having a tamper-evident seal. In particular, a tamper-evident seal is a device by means of which a user or consumer can recognize whether a package or container is still in its original packaging state or is closed and has not been opened. For example, such a tamper-evident seal can be formed by a sticker which is attached in such a way that the sticker is damaged or destroyed when the package or container is opened (for the first time).

[0004] US 3,848,778A relates to a child-resistant actuator assembly, wherein an actuator button is mounted in a housing to form an actuator assembly, which is fixed to a sprayer or other container with a valve. The actuator button can rotate between a non-dispensing position and a dispensing position. When the actuator button is in the non-dispensing position, the matable portion of the actuator assembly forms a locking device to reliably prevent the rotational movement of the actuator button, and at the same time, the blocking device prevents the operation of the dispensing valve. When the locking device is disabled by disengaging the matable portion, the actuator button is simultaneously rotated to the dispensing position without being restricted by the blocking device to dispense the product from the container by operating the valve, such as by pressing the actuator button or tilting the actuator button.

[0005] DE 199 42 791 A1 relates to a device for dispensing a medium. The device comprises two one-piece housing parts for receiving medium blisters. To prevent damage and also to prevent accidental actuation, a locking element is provided for the rest position, which allows the housing parts to be separated and rotated relative to each other.

[0006] US 4796770 A relates to an injection molded plastic enclosure having a tamper-indicating portion. The tamper-indicating portion comprises a tamper-indicating band attached to a skirt for being hinged radially outwardly by a plurality of bridges. The tamper-indicating band is susceptible to breaking so that it can expand outwardly and make the container neck finish visible. The tamper-indicating band remains attached to the enclosure, and rupture of the tamper-indicating band indicates tampering.

[0007] EP 4 008 442 A1 relates to a dispensing device for dispensing a fluid. The dispensing device has a delivery device for delivering the fluid from a container, which can be actuated by means of an actuating rod, which can be locked by means of a locking device to prevent accidental actuation. In order to release the lock, the actuating rod is preferably mounted in a displaceable manner. The dispensing device may also include a fixing device, which fixes the actuating rod by means of the locking device to prevent unlocking.

[0008] US 4,324,351 A relates to a dispensing actuator comprising a button rotatable between two stops between a dispensing position and a non-dispensing position, the button having a protrusion engaging with the stops to avoid overrunning the stops in the dispensing position, the protrusion having an inwardly extending lip abutting against the stops.

[0009] US2003 / 0150876 A1 relates to a product discharge assembly for a container of a fluid substance. A finger-operable pump barrel is arranged in a closure for mounting the pump barrel and the closure to a container. An actuator is mounted on the pump barrel. A shield is mounted around the closure. The actuator has a skirt having a flange extending from the skirt and continuously surrounding the skirt. The shield has a lip for engaging with the actuator flange to prevent the actuator from being removed from the rod when the actuator moves outwardly beyond a predetermined position relative to the rod. The actuator and the closure may also include a mating mutually engageable feature to accommodate the rotation of the actuator relative to the closure between an actuable position allowing the actuator to reciprocate and a releasable locking position preventing the actuator from reciprocating. Summary of the invention

[0010] The object of the present invention is to provide a dispensing head with a tamper-evident seal, wherein the dispensing head is designed to be user-friendly and easy to handle and / or wherein the dispensing head can be reused in a simple manner.

[0011] The above object is solved by a dispenser head according to claim 1 or a dispenser according to claim 25. Further advantageous embodiments are subject matter of the dependent claims.

[0012] The invention relates to a dispensing head for a dispenser for dispensing a fluid. The dispensing head comprises a housing part and an actuator, which can be rotated relative to the housing part to actuate the dispensing head or the dispenser. In addition, the dispensing head, in particular the housing part, has a tamper-evident seal.

[0013] According to a first aspect of the invention, the actuator and the tamper-evident seal are configured such that: when the actuator is rotated from a first rotational position to a second rotational position relative to the housing part for the first time, the actuator applies a force to the tamper-evident seal, which causes the tamper-evident seal to be damaged and / or actuated. In particular, the force applied to the tamper-evident seal is a force directed radially outwardly in the rotational direction of the actuator. In other words, the actuator preferably presses against the tamper-evident seal, in particular in a radial direction and / or in the rotational direction of the actuator. On the one hand, this reliably achieves damage to the tamper-evident seal when the actuator is rotated for the first time, so that the tamper-evident seal reliably indicates when the dispensing head has been used. In addition, this contributes to a simple and user-friendly operation of the dispensing head. In particular, no additional steps are required to damage the tamper-evident seal, or damage to the tamper-evident seal advantageously occurs during the steps required to actuate the dispensing head or during the movement of the actuator required to actuate the dispensing head.

[0014] According to another aspect of the invention, which can also be realized independently, the tamper-evident seal is formed in an integral manner with the housing part. In other words, the tamper-evident seal constitutes a part of the housing part. Thus, in particular, the tamper-evident seal is not formed as a separate or distinct part from the housing part. This contributes to easy and / or inexpensive manufacturing of the dispensing head and to easy and user-friendly operation.

[0015] The housing part or the dispensing head is preferably designed such that the tamper-evident seal, in particular the body of the tamper-evident seal, is formed in an integral manner with the housing part or the tamper-evident seal, in particular the body of the tamper-evident seal, is connected to the housing part even after being damaged and / or actuated due to the rotation of the actuator. In particular, the tamper-evident seal remains connected to the housing part or the tamper-evident seal cannot be separated from the dispensing head or the housing part due to damage and / or actuation. This facilitates handling and does not require separate handling of separated components. As a result, the dispensing head is also easier to reuse.

[0016] The tamper-evident seal preferably has at least one breakable connecting arm. In particular, the connecting arm can be broken due to a (first) rotation of the actuator. The tamper-evident seal or its body is connected to the housing part via at least one connecting arm. In particular, the breakable connecting arm allows the tamper-evident seal to be damaged due to a rotation of the actuator.

[0017] The tamper-evident seal preferably has a flexure bearing or an area of ​​reduced material thickness. The tamper-evident seal or its body is connected to the housing part via the flexure bearing or the area of ​​reduced material thickness. On the one hand, this allows the tamper-evident seal to be damaged or actuated, in particular by forces directed in the direction of rotation of the actuator and / or radially outwards, when the actuator is rotated for the first time, and on the other hand, prevents the tamper-evident seal from being completely separated from the housing part. In addition, the flexure bearing or the area of ​​reduced material thickness allows the tamper-evident seal to not hinder the operation of the dispensing head, in particular the rotation of the actuator, after the initial rotation, even if the tamper-evident seal is not completely separated from the housing part.

[0018] Preferably, the tamper-indicating seal is arranged on the upper edge of the housing part, in particular completely on the upper edge of the housing part. Further preferably, the tamper-indicating seal protrudes inwardly and / or downwardly from the inner wall of the housing part. Thereby, the tamper-indicating seal preferably interacts with the actuator in a coordinated manner, so that by rotation of the actuator, a force directed in the rotation direction of the actuator and / or radially outwardly is exerted on the tamper-indicating seal, thereby causing damage and / or actuation, or the actuator is thereby pressed against the tamper-indicating seal. Furthermore, accidental damage or actuation of the tamper-indicating seal before the first rotation of the actuator is prevented.

[0019] The tamper-evident seal is preferably configured to pivot or fold outwards after being damaged and / or actuated and / or after the first rotation of the actuator. However, the tamper-evident seal can also be designed to be arranged inside the housing part and / or to pivot or fold inwards and / or downwards after being damaged and / or actuated and / or after the first rotation of the actuator. This helps in each case not to hinder the actuation and / or use of the dispensing head after the first rotation.

[0020] The dispenser head is preferably designed such that the tamper-evident seal or its body is moved, in particular pivoted or flipped, by a rotation of the actuator or its body, in particular pivoted or flipped by at least approximately 90° and / or pivoted or flipped about an axis perpendicular and / or at least approximately radial to a central axis of the housing part or the dispenser head. This facilitates reliable and easy identification of an indication of a successful actuation or first rotation and unimpeded actuation or use of the dispenser head after the first rotation.

[0021] Preferably, the dispensing head, in particular the housing part, has a fixing device for fixing the actuated and / or damaged tamper-evident seal, in particular for fixing the body of the tamper-evident seal. The fixing device is preferably formed in an integral manner with the housing part. By means of the fixing device, the actuated and / or damaged tamper-evident seal can be prevented from falling off and / or becoming an obstacle or interfering with or impairing the function of the dispensing head during use.

[0022] In particular, the fixing device is designed for automatically fixing the tamper-evident seal. This facilitates easy handling.

[0023] The fixing device is preferably designed for fixing the tamper-evident seal or the body of the tamper-evident seal by clamping. This enables a simple and reliable fixing of the tamper-evident seal or the body.

[0024] Preferably, the fixing device is arranged on the inside of the dispensing head or the housing part. This is aesthetically advantageous on the one hand and facilitates easy operation of the dispensing head on the other hand.

[0025] The tamper-evident seal, in particular its body, preferably has arms and / or recesses. The recesses are preferably at least approximately V-shaped and / or formed between the arms. Particularly preferably, the fixing means are configured to be complementary to the arms and / or recesses and / or the arms and / or recesses are configured for fixing the tamper-evident seal or its body. This enables the tamper-evident seal to be fixed (automatically) in a simple and reliable manner.

[0026] The actuator preferably has a driver for applying a force to the tamper-evident seal and / or for actuating and / or damaging the tamper-evident seal. In particular, the driver is designed to press against the tamper-evident seal when the actuator is (for the first time) rotated from the first rotational position to the second rotational position. This enables a reliable and / or automatic actuation or damage of the tamper-evident seal, thereby reliably indicating that use has occurred.

[0027] Preferably, the actuation or axial movement of the actuator is blocked in the first rotational position, while the actuation or axial movement of the actuator is allowed in the second rotational position. In other words, the actuator can preferably be blocked from actuation by rotating to the first rotational position. This prevents accidental actuation or accidental leakage of the fluid. In addition, the tamper-evident seal cooperates with this locking function of the actuator: in the delivery state, the actuator is preferably in the first rotational position and is therefore locked from actuation. In order to actuate the actuator (which is particularly achieved by axial movement or downward pressing of the actuator), it is preferably necessary to rotate the actuator from the first rotational position to the second rotational position. In an advantageous manner, this (first) rotation damages the tamper-evident seal, so that the damage to the tamper-evident seal is caused by the steps necessary to actuate the actuator, or no additional steps are required to put the dispensing head in an operational or dispensing ready state.

[0028] The actuator is preferably rotationally asymmetric about an axis of rotation, in particular the axis of rotation from the first rotational position to the second rotational position. Preferably, the actuator has a rotationally asymmetric outer contour portion. Particularly preferably, the outer contour portion is arc-shaped in a first sector or angular range and is rectilinear in a second sector or angular range. This allows the tamper-evident seal to be damaged when the actuator is rotated for the first time.

[0029] The dispenser head is preferably at least partially arranged in the housing part and / or enclosed by the housing part. The housing part is preferably sleeve-shaped and / or rests on the actuator.

[0030] According to another aspect, the present invention also relates to a dispenser for dispensing a fluid, comprising a dispensing head constructed as described herein.

[0031] The aspects and features mentioned above as well as further aspects and features arising from the claims and the following description can be realized independently of one another and in various combinations. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The fluid F is preferably contained in the dispenser 1 or in the container 2. Via the dispensing head 3, the fluid F can be conveyed from the container 2 to a user, not shown, and / or the fluid F can be dispensed from the dispenser 1 to a user, not shown.

[0049] The dispensing head 3 has a housing part 4 and an actuator 5 which can rotate relative to the housing part 4. The actuator 5 is used in particular to actuate the dispensing head 3 and / or the dispenser 1. The actuation of the actuator 5 or the dispensing head 3 or the dispenser 1 is in particular performed by pressing the actuator 5 downwards, so that the fluid F is preferably conveyed to the outside of the container 2 and dispensed by the dispensing head 3.

[0050] The dispensing head 3 and / or the actuator 5 can be designed as a spray head and / or can be designed to dispense the fluid F in the form of a spray or an aerosol.

[0051] The housing part 4 is preferably formed as a sleeve, a flange and / or a ring. The housing part 4 is preferably sleeved on the actuator 5.

[0052] The dispenser 1 and / or the container 2 and / or the dispensing head 3 preferably have a central or longitudinal axis A. The central or longitudinal axis A is referred to hereinafter as axis A for short. Designations such as "axial" and "radial" preferably refer to the axis A. Thus, an axial direction or an axial extension is preferably a direction, extension or movement along or parallel to the axis A. Thus, a radial direction is a direction radial to the axis A.

Preferably, the valve spring 12B is formed in an integral manner with the valve stem 12A. Preferably, the valve stem 12A and / or the valve spring 12B are made of the same material and / or are made of plastic.

[0056] By means of the pump, fluid F can be conveyed from a container 2 of the dispenser 1 and dispensed via a dispensing head 3 . The piston 7 is axially movable to convey the fluid F via an inlet 9 to a pump chamber 8 and from the pump chamber 8 to an outlet 10 .

[0057] The pump is preferably arranged within the housing part 4 and / or enclosed by the housing part 4 .

[0058] The dispensing head 3 preferably has a reset device 13, which is in particular a reset spring, for biasing and / or resetting the piston 7 and / or the actuator 5 to an initial position. In the example shown, the reset device 13 is designed as a spring bellows and / or is made of plastic. However, other solutions are also possible here, for example, the reset device 13 is designed as a metal and / or a helical spring.

[0059] The actuator 5 is preferably attached to the piston 7, in particular so that the piston 7 and the actuator 5 move together in the axial direction, in particular when the actuator 5 is moved from Figure 1 When the initial position shown in FIG. 1 is initially actuated or pressed downwards in the direction of the container 2 and / or is moved back to the initial position, in particular by means of the resetting device 13 , the piston 7 and the actuator 5 are moved together in the axial direction.

[0060] The dispense head 3 preferably has a mounting portion 14. The mounting portion 14 is preferably arranged inside the housing portion 4 and / or is enclosed by the housing portion 4.

[0061] The mounting portion 14 is preferably mounted to the container 2 or can be mounted to the container 2 , in particular to an upper edge of the container 2 , for example screwed to the container 2 .

[0062] Preferably, the pump or pump housing 6 is attached to and / or held by the mounting portion 14 .

[0063] The resetting device 13 is preferably supported on the mounting portion 14 and / or is arranged between the actuator 5 and the mounting portion 14 .

[0064] Preferably, the housing part 4 is connected to the mounting part 14 in a non-rotatable manner.

[0065] The dispensing head 3 , in particular the housing part 4 , has a tamper-evident seal 15 .

[0066] The tamper-evident seal 15 is preferably designed to indicate or represent the original state of the dispensing head 3 or the dispenser 1. Specifically, the tamper-evident seal 15 is designed to indicate or represent to the user whether the dispensing head 3 or the dispenser 1 has been used. This is achieved in particular by causing the tamper-evident seal 15 to be activated and / or damaged when the dispensing head 3 is (necessarily) used for the first time.

[0067] Figure 2 The dispensing head 3 is shown in a perspective view, in particular from the front. Figure 3 and Figure 4, the dispensing head 3 is also shown in a perspective view, but here in particular viewed from the rear side.

[0068] Especially in Figure 1 , Figure 3 and Figure 4 A tamper-evident seal 15 is shown in FIG.

[0069] The tamper-evident seal 15 is preferably configured to be actuated and / or destroyed by a (first) rotation of the actuator 5 , in particular about the axis A and / or relative to the housing part 4 .

[0070] In the present invention, "activation" of the tamper-evident seal 15 is understood in particular to be an action on the tamper-evident seal 15 by means of which the tamper-evident seal 15 is moved, in particular pivoted and / or folded downwards, and or by means of which the tamper-evident seal 15 is damaged. In particular, the actuation of the tamper-evident seal 15 takes place automatically and / or by means of the actuator 5. In particular, the actuation of the tamper-evident seal 15 is a pressing against the tamper-evident seal 15, particularly preferably a pressing against the tamper-evident seal 15 by means of the actuator 5.

[0071] In particular, an undamaged or unactivated state of the tamper-evident seal 15 indicates or represents to the user that the dispensing head 3 or the actuator 5 has not been activated or used. An actuated or damaged tamper-evident seal 15 indicates or represents to the user that the dispensing head 3 or the dispenser 1 is no longer in its original or delivered state or that the dispensing head 3 or the dispenser 1 has been used / activated.

[0072] Preferably, the actuator 5 can be positioned or arranged in different rotational positions relative to the axis A or the housing part 4, in particular in a first rotational position and a second rotational position different from the first rotational position, or the actuator 5 can be rotated between the first rotational position and the second rotational position. The axis A particularly denotes the rotational axis of the actuator 5 or the rotational axis from the first rotational position to the second rotational position.

[0073] exist Figure 3 In FIG. 1 , the actuator 5 is shown in a first rotational position, while in FIG. Figure 4 , the actuator 5 is shown in the second rotational position. Preferably, there is a rotation angle of about 90° around the axis A between the first rotational position and the second rotational position.

[0074] Preferably, the actuator 5 is rotatable relative to the housing part 4 , in particular about the axis A.

[0075] Preferably, at least in the second rotational position, the actuator 5 is movable in the axial direction relative to the axis A and / or the housing part 4. Particularly preferably, an actuation and / or an axial movement of the actuator 5 is blocked in the first rotational position, whereas an actuation and / or an axial movement of the actuator 5 is allowed in the second rotational position. In other words, the actuator 5 is thus preferably blocked from actuation and / or axial movement, in particular from being pushed axially downwards in the direction of the container 2. This will be discussed in more detail below.

[0076] exist Figure 3 In FIG, the tamper-evident seal 15 is shown in a delivered and / or original state and / or in an undamaged and / or unactivated state. Figure 4 In FIG. 1 , the tamper-evident seal 15 is shown in a damaged and / or actuated state.

[0077] The tamper-evident seal 15 is preferably configured to be actuated and / or broken before or during a first actuation of the actuator 5 and / or the dispensing head 3 and / or the dispenser 1 .

[0078] Preferably, the tamper-evident seal 15 is formed in an integral or one-piece manner with the housing part 4. In particular, the tamper-evident seal 15 forms a section or a part of the housing part 4. Preferably, the tamper-evident seal 15 is firmly or inseparably connected to the housing part 4.

[0079] In other words, the housing part 4 preferably has two sections, or the housing part 4 comprises two sections, namely the tamper-evident seal 15 and a section surrounding the tamper-evident seal 15 .

[0080] The tamper-evident seal 15 is preferably made of the same material as the material of the housing part 4. In particular, the housing part 4 and / or the tamper-evident seal 15 are made of plastic.

[0081] The tamper-evident seal 15 is preferably injection-moulded with the housing part 4 .

[0082] The tamper-evident seal 15 preferably has a body 16 .

[0083] The tamper-evident seal 15 preferably has at least one connecting arm 17. The tamper-evident seal 15 and / or the body 16 are preferably connected to the housing part 4 via the connecting arm 17. In particular, the connecting arm 17 is formed in an integral or one-piece manner with the tamper-evident seal 15 and / or the body 16 and the housing part 4. In particular, the connecting arm 17 can be broken by a rotation or a first rotation of the actuator 5 relative to the tamper-evident seal 15 and / or the housing part 4, in particular a rotation or a first rotation from a first rotation position to a second rotation position, or the connecting arm 17 is designed to break during a first rotation of the actuator 5 from the first rotation position to the second rotation position.

[0084] The connecting arm 17 preferably protrudes from the body 16 in circumferential direction and / or in tangential direction, in particular in circumferential direction and / or in tangential direction relative to the axis A. Preferably, the connecting arm 17 is arranged at the top of the body 16 .

[0085] In the illustrated example, the tamper-evident seal 15 has two connecting arms 17 , in particular wherein the two connecting arms 17 of the tamper-evident seal 15 are designed in the same manner. Therefore, the statements made with respect to the at least one connecting arm 17 preferably apply to both connecting arms 17 .

[0086] The tamper-evident seal 15 preferably has a flexure bearing 18. The flexure bearing 18 is preferably designed as a movable hinge. The tamper-evident seal 15 and / or the body 16 are preferably connected to the housing part 4 via the flexure bearing 18. The body 16 is preferably pivotable about the flexure bearing 18. The pivot axis preferably extends in a manner at least approximately perpendicular to the axis A.

[0087] In particular, the tamper-evident seal 15 has a portion of reduced material thickness and / or the flexure bearing 18 is formed by a portion of reduced material thickness.

[0088] The flexure bearing 18 is preferably formed by an extension of an at least approximately (hollow) cylindrical wall portion 19 of the shell part 4. Preferably, the material thickness of the flexure bearing 18, in particular the material thickness in the radial direction, is reduced compared to the material thickness of the wall portion 19 and / or the main body 16. In other words, the thickness or material thickness of the flexure bearing 18 is preferably smaller than the thickness or material thickness of the wall portion 19 and / or the main body 16, in particular, the thickness or material thickness of the flexure bearing 18 measured radially relative to the axis A is preferably smaller than the thickness or material thickness of the wall portion 19 and / or the main body 16 measured radially relative to the axis A. This can be achieved in particular in Figure 1 Seen in.

[0089] Preferably, the flexure bearing 18 is arranged on the body 16 at the bottom or on the side facing the container 2 .

[0090] The body 16 is preferably connected to the housing part 4 by means of connecting arms 17 and / or flexure bearings 18 or is formed in an integral manner with the housing part 4. In particular, the body 16 is held to the housing part 4 by means of the connecting arms 17 and / or the flexure bearings 18.

[0091] The dispensing head 3 and / or the tamper-evident seal 15 are preferably designed such that after the tamper-evident seal 15 has been actuated and / or damaged, in particular after one or more connecting arms 17 have been broken, or after the actuator 5 has been rotated for the first time, the tamper-evident seal 15 and / or the body 16 are folded outwardly or pivoted from the housing part 4. This is achieved in particular by pivoting the flexure bearing 18 or the body 16 about the flexure bearing 18.

[0092] The connecting arm 17 and the flexure support portion 18 are preferably designed or matched to each other so that: when the actuator 5 is rotated (for the first time) from the first rotational position to the second rotational position, the connecting arm 17 breaks, thereby damaging the tamper-evident seal 15, and at the same time the flexure support portion 18 remains intact and allows the tamper-evident seal 15 or the main body 16 to move, in particular allowing the tamper-evident seal 15 or the main body 16 to move outward.

[0093] The housing part 4 preferably has a wall part 19 and / or an (upper) edge 20 .

[0094] The wall portion 19 is preferably at least substantially cylindrical or hollow cylindrical in shape. The wall portion 19 preferably has or forms an outer surface 22 in the form of a cylindrical surface.

[0095] The edge 20 is preferably arranged on the upper side of the housing part 4 and / or the wall part 19 and / or on the side facing away from the container 2 .

[0097] The tamper-evident seal 15 is preferably arranged at the upper end of the cylindrical wall portion 19 and / or at the end facing away from the container 2 and / or at or in the vicinity of the edge 20 .

[0098] Preferably, the tamper-evident seal 15 and / or the body 16 are connected to the wall portion 19 by means of flexure bearings 18 and / or to the edge 20 by means of connecting arms 17 .

[0099] Preferably, the body 16 is connected to the wall portion 19 via a flexure bearing 18 on its bottom side and is separated from the wall portion 19 and / or the edge 20 in a lateral direction or in a circumferential direction around the rotation axis A, in particular by a slot or a slot-like opening. Preferably, the connecting arm 17 bridges the slot.

[0100] The tamper-evident seal 15 and / or the body 16 preferably protrude inwardly and / or radially and / or in the direction of the axis A from the housing part 4 and / or the wall part 19 , in particular from an inner wall of the housing part 4 or the wall part 19 .

[0101] Figure 5 1 shows a perspective view of the actuator 5. In particular, Figure 5 The interior of the actuator 5 is shown or can be seen in FIG.

[0102] The actuator 5 is preferably rotationally asymmetric, in particular rotationally asymmetric about the axis A. Preferably, the actuator 5 has a rotationally asymmetric outer contour portion 21 , in particular rotationally asymmetric in the radial direction about the axis A or the axis of rotation.

[0103] The actuator 5 preferably has a cylindrical outer surface 22. The axis A is preferably the axis of symmetry or the longitudinal axis of the cylindrical outer surface 22.

[0104] The outer profile portion 21 is preferably arranged at the lower end or the end facing the container 2 of the actuator 5 and / or the outer surface 22 .

[0105] In particular, the outer profile portion 21 protrudes radially outward from the outer surface 22 .

[0106] The outer contour section 21 in particular forms an (outer) edge or a stop. The outer contour section 21 is in particular assigned to the edge 20 of the housing part 4 and / or engages behind the edge 20 of the housing part 4 .

[0107] Preferably, the outer contour portion 21 extends in the shape of a circular arc in a first sector or angular range around the axis A or the rotation axis, and extends in a straight line in a second sector or angular range around the axis A or the rotation axis, in particular tangentially or perpendicularly to the axis A. However, in principle other solutions are also possible, such as an oval, elliptical or polygonal outer contour portion 21.

[0108] In other words, the outer contour portion 21 is preferably at least substantially circular in shape, which is flat or has a flattened portion in a region, in particular in a sector or corner region.

[0109] The dispensing head 3 or the actuator 5 and the tamper-indicating seal 15 are preferably designed such that the tamper-indicating seal 15 is or can be actuated and / or damaged by a (first) rotation of the actuator 5 from the first rotational position to the second rotational position. In particular, the dispensing head 3 or the actuator 5 and the tamper-indicating seal 15 are designed such that during the first rotation relative to the housing part 4 from the first rotational position to the second rotational position, the actuator 5 comes into contact with the tamper-indicating seal 15 or the body 16, respectively, and / or the actuator 5 exerts a force, in particular a radially outwardly directed force, on the tamper-indicating seal 15 or the body 16, respectively, or the actuator 5 presses (radially) against the tamper-indicating seal 15 or the body 16, respectively. The force exerted on the tamper-indicating seal 15 or the body 16 in particular causes the tamper-indicating seal 15 to be actuated and / or damaged, particularly preferably causes one or more connecting arms 17 to break.

[0110] In other words, the tamper-evident seal 15 is preferably adapted to be actuated and / or broken upon a first rotation of the actuator 5 .

[0111] Furthermore, the housing part 4 is preferably configured such that the tamper-evident seal 15 remains integral or in one piece with the housing part 4 even after the actuator 5 has been actuated or damaged or the connecting arm 17 has broken due to a (first) rotation of the actuator 5. In other words, the housing part 4 or the dispensing head 3 is preferably configured such that after a (first) rotation of the actuator 5, the tamper-evident seal 15 or the body 16 continues to be connected to the housing part 4, in particular via the flexure bearing 18.

[0112] Preferably, then, the dispensing head 3 is constructed so that: when the actuator 5 is rotated from the first rotational position to the second rotational position for the first time, one or more connecting arms 17 break, so that the tamper-evident seal 15 is damaged, but the solid joint 18 is not damaged or remains intact, and the tamper-evident seal 15 remains connected to the housing part 4 via the flexure support 18, even after the connecting arm 17 breaks or is damaged.

[0113] Thus, the tamper-evident seal 15 is preferably prevented from being completely separated from the housing part 4. This facilitates handling and makes the dispensing head 3 user-friendly, in particular because no separate parts need to be handled separately.

[0114] Preferably, the force exerted on the tamper-evident seal 15 during the rotation of the actuator 5 is caused by the rotational asymmetry of the actuator 5. In particular, the actuator 5 or the outer profile 21 is rotationally asymmetric, so that when the actuator 5 is rotated about the rotation axis, the outer edge of the actuator 5 or the outer profile 21 increases in distance from the rotation axis in the direction of the tamper-evident seal 15 and / or decreases in distance from the tamper-evident seal 15 and / or the body 16, so that the actuator 5 or the outer profile 21 slides along the tamper-evident seal 15 or its body 16 and presses the body 16 outwardly. The force exerted in this way eventually causes the connecting arm 17 to break and / or the tamper-evident seal 15 to fold down or pivot outwardly, in particular via the flexure bearing 18.

[0115] In the first rotational position of the actuator 5 , the distance of the outer contour portion 21 or its edge from the rotational axis in the direction of the tamper-evident seal 15 is preferably minimal and / or smaller than in at least one other rotational position.

[0116] Particularly preferably, in the first rotational position, the sector or angular area of ​​the outer profile portion 21 extending linearly or tangentially with respect to the axis A is oriented towards the tamper-evident seal 15. Then, the rotation of the actuator 5 from the first rotational position to the second rotational position causes the arcuate sector or angular area to come into contact with the tamper-evident seal 15. Since the outer edge of the arcuate sector or angular area is at a greater distance from the axis A than a linear sector, this presses the tamper-evident seal 15 or the body 16 outwards.

[0117] Preferably, the dispensing head 3 is designed so that: the axial movement of the actuator 5 downward or in the direction of the pump or container 2 is blocked in the first rotational position and unblocked in the second rotational position. In other words, the actuation of the actuator 5, in particular for dispensing the fluid, is blocked in the first rotational position and allowed in the second rotational position.

[0118] Thus, the dispenser head 3 can be locked by rotating the actuator 5 into the first rotational position and / or have a twist-locking function.

[0119] Preferably, the twist lock function is basically implemented according to the content described in US2003 / 0150876 A1. Therefore, only a brief description of this function is given below, and other contents refer to US2003 / 0150876 A1.

[0120] In particular, Figure 6 and Figure 7 The functionality of the twist lock feature can be seen in the figure. Figure 6 A cross-sectional view of the actuator 5 and the mounting portion 14 is shown. Figure 7 A perspective view of the mounting portion 14 is shown.

[0121] also, Figure 6 The actuator 5 is shown in a second rotational position, wherein the actuator 5 has been rotated from Figure 1 The position shown in FIG. 1 has been moved axially downward.

[0122] Preferably, the dispenser head 3, in particular the mounting portion 14, has a blocking device 23 for blocking the axial movement of the actuator 5 outside the first rotational position and / or the second rotational position. The blocking device 23 is preferably at least approximately cylindrical or sleeve-shaped.

[0123] Preferably, the actuator 5 has at least one, preferably a plurality of, ribs 24A, 24B, which are in particular assigned to the blocking means 23 and / or are operatively connected to the blocking means 23. The ribs 24A, 24B are preferably arranged on the inside of the actuator 5, in particular on the inside of a wall portion of the actuator 5 forming the outer surface 22 or comprising the outer surface 22.

[0124] The ribs 24A, 24B, in particular pairs of ribs, preferably represent reinforcements and / or supports for the actuator 5. Preferably, the ribs 24A, 24B prevent or reduce deformations of the actuator 5, in particular during rotation.

[0125] Preferably, the ribs 24A, 24B are elongated and / or extend parallel to the axis A.

[0126] In particular, the actuator 5 has a plurality of pairs of ribs 24A, 24B and / or the ribs 24A, 24B are arranged in pairs in the actuator 5. In the illustrated example, the actuator 5 has three pairs of ribs 24A, 24B, i.e. a total of six ribs 24A, 24B. The three pairs of ribs 24A, 24B are preferably arranged in a symmetrical manner and / or are each offset by about 120° from each other around the axis A.

[0127] Each pair of ribs preferably has a first rib 24A and a second rib 24B. The distance between the two ribs 24A, 24B in a pair of ribs is preferably smaller than the distance from the other ribs 24A, 24B or smaller than the distance from the ribs 24A, 24B of other pairs of ribs.

[0128] The ribs 24A, 24B are preferably identical in shape.

[0129] The blocking device 23 preferably has a blocking surface 25. The blocking surface 25 preferably forms an upper edge of the blocking device 23 or has an upper edge of the blocking device 23.

[0130] The blocking surface 25 preferably cooperates with the ribs 24A, 24B. In particular, the ribs 24A, 24B and the blocking surface 25 are configured so that: in the first rotational position, the ribs 24A, 24B abut or rest on the blocking surface 25 and / or prevent an axial movement of the actuator 5 in the direction of the blocking device 23 or the blocking surface 25, in particular by making the ribs 24A, 24B contact the blocking surface 25 during the downward movement of the actuator 5 or the movement of the actuator 5 in the direction of the container 2.

[0131] The blocking surface 25 is preferably interrupted and / or has a plurality of mutually separated parts, in the illustrative example three mutually separated parts, which are preferably located in the same plane. Preferably, each of these parts is assigned to a pair of ribs.

[0132] Furthermore, the blocking device 23 has at least one recess 26. The recess 26 is formed to receive the ribs 24A, 24B, preferably the pair of ribs 24A, 24B. In the recess 26, the upper edge of the blocking device 23 is lowered downward relative to the blocking surface 25. In particular, when the actuator 5 is in the second rotational position, the recess 26 allows the actuator 5 to move axially downward.

[0133] In the example shown, the blocking device 23 has three recesses 26. The recesses 26 are preferably arranged in a symmetrical manner and / or are each offset from one another by approximately 120° about the axis A. Preferably, each of the recesses 26 is assigned to a pair of ribs.

[0134] The blocking device 23 preferably has at least one stop 27 .

[0135] In the example shown, the blocking device 23 has three stops 27. The stops 27 are preferably arranged in a symmetrical manner and / or offset from one another around the axis A by approximately 120°.

[0136] In particular, the stop 27 defines or determines the first rotational position and the second rotational position, in particular together with the ribs 24A, 24B. Preferably, the stop 27 protrudes upwards from the blocking surface 25.

[0137] In the first rotational position, the ribs 24A, 24B preferably rest on the blocking surface 25 and / or the blocking surface 25 together with the ribs 24 prevent the actuator 5 from moving axially downward. Furthermore, the stop 27 preferably blocks the actuator 5 from rotating in the opposite direction to the second rotational position starting from the first rotational position. Thus, starting from the first rotational position, the actuator 5 is preferably only able to rotate in the direction of the second rotational position, while the stop 27 prevents a rotation in the opposite direction, in particular by the ribs 24A, 24B contacting the stop 27.

[0138] When the actuator 5 rotates in the direction of the second rotational position and / or reaches the second rotational position, the rib 24 is located above the recess 26, so that the actuator 5 can move downward in the second rotational position. In particular, when the actuator 5 moves downward, the ribs 24A, 24B move into the recess 26. Preferably, one pair of the paired ribs 24A, 24B moves into each recess in the recess 26. Preferably, in particular, by the ribs 24A, 24B contacting the stop 27, a rotation beyond the second rotational position and / or a rotation starting from the second rotational position in the rotational direction from the first rotational position to the second rotational position is prevented by the stop 27.

[0139] Each pair of ribs 24A, 24B is preferably arranged between two stops 27 .

[0140] Preferably, the actuator 5 is prevented from rotating beyond the second rotational position in the rotational direction from the first rotational position to the second rotational position by the second rib 24B of the pair of ribs in each case coming into contact with the stop 27. Preferably, the actuator 5 is prevented from rotating beyond the first rotational position in the rotational direction from the second rotational position to the first rotational position by the first rib 24A of the pair of ribs in each case coming into contact with the stop 27.

[0141] The ribs 24A, 24B, the recesses 26 and / or the stops 27 are preferably designed and / or arranged such that: when the actuator 5 is rotated from the first rotational position to the second rotational position, a rotational angle of about 90° is swept, and / or the first rotational position and the second rotational position differ by a rotational angle of about 90°. However, other solutions are also possible here.

[0142] The actuator 5 preferably has at least one or two latching projections 28A, 28B, in the illustrative example six latching projections 28A, 28B. The latching projections 28A, 28B are preferably arranged on the inner side of the actuator 5, in particular on the inner side of the wall portion of the actuator 5 forming or including the outer surface 22.

[0143] Preferably, the latching protrusions 28A, 28B are elongated and / or extend in parallel with the axis A.

[0144] The latching protrusions 28A, 28B preferably cooperate with the ribs 24A, 24B and / or the stop 27. In particular, the latching protrusions 28A, 28B are used to define the first rotational position and / or the second rotational position and / or latch and / or fix the actuator 5 in the first rotational position and / or the second rotational position.

[0145] Preferably, two latching projections 28A, 28B are assigned to each pair of ribs 24A, 24B. The ribs 24A, 24B in a pair of ribs are preferably arranged between the two latching projections 28A, 28B belonging to each other. This is particularly true in Figure 5 In particular, the first latching protrusion 28A is assigned to each first rib 24A, and / or the second latching protrusion 28B is assigned to each second rib 24B.

[0146] The distance between the ribs 24A, 24B and the latching projections 28A, 28B assigned to the ribs 24A, 24B preferably corresponds approximately to the width of the stop 27, in particular so that the stop 27 can be arranged between the first rib 24A and the first latching projection 28A or between the second rib 24B and the assigned second latching projection 28B, respectively, and in particular the stop 27 can be latched there. This is for example Figure 6 As shown in .

[0147] When the actuator 5 is in the first rotational position, the stop 27 is preferably arranged, in particular clamped and / or latched, between the second rib 24B and the assigned respective second latching projection 28B, respectively.

[0148] When the actuator 5 is in the second rotational position, the stop 27 is preferably arranged between the first rib 24A and the corresponding second locking projection 28A assigned, in particular clamped and / or latched between the first rib 24A and the corresponding second locking projection 28A assigned. For the second rotational position, this is particularly Figure 6 As shown in .

[0149] Thus, by means of the latching projections 28A, 28B, in particular in cooperation with the stop 27 and / or the ribs 24A, 24B, in particular an (improved) latching or snapping of the actuator 5 in the first rotational position and / or in the second rotational position is achieved.

[0150] The dispensing head 3 is preferably designed to emit an acoustic signal when reaching and / or leaving the second rotational position. The acoustic signal in particular indicates reaching the second rotational position and thus unlocking or blocking the axial movement of the actuator 5. The acoustic signal is preferably a click or a crackle or the like.

[0151] The dispensing head 3 preferably has a signaling device 29 for generating an acoustic signal. The signaling device 29 is preferably arranged in one of the recesses 26. Preferably, the signaling device 29 extends upward from the bottom of the recess 26 in a rod-like manner, and / or the recess 26 is divided into two areas by the signaling device 29, in particular into two gaps 30A, 30B, preferably wherein each of the gaps 30A, 30B is designed to receive the ribs 24A, 24B.

[0152] The signaling device 29 preferably extends parallel to the axis A.

[0153] Preferably, the signaling device 29A is elastic and / or flexible, in particular such that the signaling device 29A is bendable or can be bent by contact with the rib 24A.

[0154] The signaling device 29 preferably extends upwards beyond the blocking surface 25. In other words, the upper tip end or the upper end 29A of the signaling device 29 is located above the plane formed by the blocking surface 25 and / or above the plane in which the blocking surface 25 is located. In particular, this achieves that when the actuator 5 is rotated from the first rotational position to the second rotational position, the rib 24A of the actuator 5 contacts the signaling device 29 or the upper end 29A of the signaling device 29, and in particular slightly bends the signaling device 29 or the upper end 29A of the signaling device 29.

[0155] The signaling device 29 is preferably designed to be flexible and / or elastic, so that during rotation, the signaling device 29 first bends slightly due to contact with the rib 24A, and then quickly returns to the initial position before bending. At this time, in particular, an acoustic signal is generated, in particular by making the signaling device 29 contact with the ribs 24A, 24B when returning quickly to generate an acoustic signal.

[0156] The actuation or operation of the dispensing head 3 or the dispenser 1 is carried out in the following manner:

[0157] In the delivery state and / or before the first operation / use, the actuator 5 is preferably arranged in the first rotational position. In particular, the actuator 5 is locked in the first rotational position by means of the stop 27A and the first rib 24A corresponding to the stop 27A and the first latch protrusion 28A.

[0158] In the first rotational position, pushing the actuator 5 downwards in the direction of the container 2 is preferably blocked, so that the fluid F cannot be dispensed in the first rotational position.

[0159] Therefore, in order to enable the dispensing of the fluid, the actuator 5 preferably must first be moved from the first rotational position to the second rotational position, in particular rotated about the axis A from the first rotational position to the second rotational position.

[0160] The arrival of the second rotational position is preferably notified by an acoustic signal generated by means of the signaling device 29 and / or one of the first ribs 24A. Movement beyond the second rotational position is preferably prevented by the first rib 24A and the stop 27, since when the second rotational position is reached, the first rib 24A comes into contact with the stop 27, thereby blocking further movement beyond the second rotational position.

[0161] Preferably, the actuator 5 is latched in the second rotational position by means of the first rib 24A, the stop 27 and the first latching projection 28A.

[0162] In the second rotational position, the actuator 5 can preferably be pushed downwards, in particular by the ribs 24A, 24B positioned above the recess 26 .

[0163] The fluid is dispensed by actuating the actuator 5 or moving or pressing the actuator 5 axially downwards in the direction of the container 2 .

[0164] When the actuator 5 is pressed downwards, the piston 7 of the pump is preferably moved or pressed downwards together with the actuator 5. This increases the pressure in the pump chamber 8, which in turn causes the outlet valve 12 to open (automatically), so that the fluid F in the pump chamber 8 is pressurized by the movement of the piston 7 and flows out through the outlet 10, and the fluid F is finally discharged through the outlet channel 31 of the actuator 5.

[0165] Depending on the circumstances, during initial use, the actuator 5 must be actuated several times in order to first fill the pump chamber 8 with the fluid F before the fluid is dispensed when the actuator 5 is depressed.

[0166] After dispensing the fluid F, the user preferably releases the actuator 5. Preferably, the actuator 5 then resets automatically, in particular by means of the reset device 13. During the reset, the actuator 5 moves upwards again, and the piston 7 moves upwards simultaneously with the actuator 5. This creates a negative pressure in the pump chamber 8, by which the inlet valve 11 opens and the fluid F is sucked from the container 2 via the inlet 9 into the pump chamber 8.

[0167] A further actuation of the dispenser head 3 or a dispensing of the fluid F can then take place, or the actuator 5 can be rotated back from the second rotational position to the first rotational position again, in particular in order to block a further or unintentional actuation of the dispenser head 3 .

[0168] In particular, the first embodiment of the dispensing head 3 has been described above, and the first embodiment is particularly Figures 1 to 7 In the following, a second embodiment of the dispensing head 3 is described, which is particularly Figures 8 to 12 As shown in .

[0169] Figure 8 and Fig. 9 A portion of a dispense head 3 according to a second embodiment is shown in a partially cut-away perspective view and in a perspective view in an original or delivery state, a state in which the tamper-evident seal 15 is not actuated or damaged. Fig.10 and Fig.11 A similar view shows a dispensing head 3 according to a second embodiment. Figure 8 and Fig. 9 The same parts, but the tamper-evident seal 15 has been actuated or broken.

[0170] exist Figure 8 and Fig.10 In the figure, for better illustration, parts of the housing part 4 have been cut away so that the interior of the dispensing head 3, in particular the tamper-evident seal 15, is clearly visible. Figure 8 and Fig.10 In the figure, the section surface is shown in hatched form.

[0171] In particular, the second embodiment differs from the first embodiment by the configuration of the tamper-evident seal 15 and by the portion of the actuator 5 which interacts with the tamper-evident seal 15 and / or is assigned to the tamper-evident seal 15 .

[0172] Therefore, in the following, the second embodiment will be mainly described in terms of differences from the first embodiment. Therefore, the above descriptions related to the first embodiment also apply to the second embodiment, as long as this does not cause any contradiction with the following descriptions related to the second embodiment.

[0173] In particular, the second embodiment is also based on an operating principle that is basically the same as the operating principle of the first embodiment, namely, the tamper-evident seal 15 is actuated and / or damaged during the first rotation of the actuator 5 from the first rotational position to the second rotational position, in particular, the tamper-evident seal 15 is actuated and / or damaged by the force applied by the actuator 5 to the tamper-evident seal 15 or its body 16.

[0174] In the second embodiment, the tamper-evident seal 15 is also preferably formed integrally or in one piece with the housing part 4. Preferably, the tamper-evident seal 15 is arranged on the upper edge 20 of the housing part 4, in particular completely on the upper edge 20 of the housing part 4.

[0175] Preferably, the actuator 5 and the tamper-evident seal 15 are configured such that: during a first rotation of the actuator 5 from the first rotational position to the second rotational position relative to the housing part 4, the actuator 5 presses against the tamper-evident seal 15 or exerts a force on the tamper-evident seal 15, so that the tamper-evident seal 15 is damaged and / or actuated. In particular, in the second embodiment, the force is a force directed in the rotational direction of the actuator 5.

[0176] Also in the second embodiment, the tamper-evident seal 15 preferably has a flexure support 18 or an area of ​​reduced material thickness, by means of which the tamper-evident seal 15 is connected to the shell part 4, in particular to the upper edge 20 of the shell part 4.

[0177] Preferably, the flexure bearing 18 has or forms a joint axis or axis of rotation B. The joint axis or axis of rotation B is referred to as axis B in the following text.

[0178] The flexure bearing 18 or the axis B preferably extends at least approximately in a radial direction. In contrast, the axis of rotation of the flexure bearing 18 in the first embodiment preferably extends at least approximately in a tangential direction.

[0179] In particular, the tamper-evident seal 15 may, in addition to the flexure bearing 18 , also have at least one breakable connecting arm 17 , by means of which the tamper-evident seal 15 or the body 16 is connected to the housing part 4 , in particular to the upper edge 20 .

[0180] However, this is not mandatory. Figures 8 to 11 In the example shown in FIG. 1 , the tamper-evident seal 15 does not have a connecting arm 17 .

[0181] The connecting arm 17 is preferably arranged on a side of the body 16 opposite to the flexure bearing 18. The connecting arm 17 preferably extends at least substantially in a radial direction.

[0182] The (first) rotation of the actuator 5 from the first rotational position to the second rotational position in particular causes the tamper-evident seal 15 to pivot or bend downwards. Particularly preferably, the tamper-evident seal 15 is pivoted or bends downwards by at least approximately 90°. The pivoting or bends downwards preferably takes place about the axis B or the flexure bearing 18. The pivoting or bends downwards by at least approximately 90° is in particular achieved by Figure 8 and Fig.10 becomes apparent by comparison.

[0183] Particularly preferably, the tamper-evident seal 15 or its main body 16 protrudes inwardly and / or downwardly from an inner wall, in particular an upper edge 20 , of the housing part 4 .

[0184] In the present invention, the term “bottom” refers in particular to the position of the dispensing head 3 or dispenser 1 shown in the figures, wherein the axis A is oriented at least approximately vertically and / or the dispensing head 3 is located on top of the dispenser 1 or container 2 .

[0185] Figure 8 The tamper-evident seal 15 or the downwardly protruding body 16 is shown protruding downwardly from the upper edge 20. Furthermore, the tamper-evident seal 15 or the downwardly protruding body 16 protruding downwardly from the upper edge 20 also protrudes inwardly from the housing part 4 or the edge 20.

[0186] In principle, however, in the second embodiment the tamper-evident seal 15 or the body 16 may also be arranged on the wall portion 19 of the housing part 4 and / or be arranged to protrude inwardly from the wall portion 19 or the housing part 4 at least in a substantially radial direction.

[0187] In a second embodiment, after the actuator 5 is damaged or actuated or rotated for the first time, the tamper-evident seal 15 is pivoted or folded inwardly and / or downwardly and / or is arranged or folded inside or on the inside of the housing part 4 and / or the dispenser head 3. This is particularly true in Fig.10 and Fig.11 As shown in .

[0188] In particular, Figure 8 and Fig. 9 In the non-actuated state shown in FIG, the tamper-evident seal 15 and / or the body 16 are flush with the housing part 4, in particular with the upper edge 20. Due to the actuation, the tamper-evident seal 15 or the body 16 is preferably pivoted or folded downwards and / or inwards. In particular, this forms a gap in the housing part 4, in particular in the upper edge 20, which is easily perceptible to the user, such as in particular in FIG. Fig.10 and Fig.11 Through this gap, the user can see that the dispenser head 3 has been used and / or that a first rotation of the actuator 5 from the first rotational position to the second rotational position has occurred.

[0189] The actuator 5 preferably has a drive 32. The drive 32 is preferably assigned to the tamper-evident seal 15 and / or is designed to actuate and / or damage the tamper-evident seal 15 or its body 16, in particular during the first rotation of the actuator 5 from the first rotational position to the second rotational position, or the drive 32 is designed to exert a corresponding force on the tamper-evident seal 15 or the body 16, in particular in the rotational direction, by means of which the actuation or damage of the tamper-evident seal 15, in particular pivoting or folding down of the tamper-evident seal 15, is achieved. In other words, the drive 32 is preferably designed to press against the tamper-evident seal 15 or the body 16, in particular during the first rotation of the actuator 5 from the first rotational position to the second rotational position.

[0190] In particular, the driver 32 is arranged outside the actuator 5. The driver 32 is preferably designed and / or arranged to exert a tangential force or a force directed in the rotational direction of the actuator 5 on the tamper-evident seal 15 or the body 16 and / or to press against the tamper-evident seal 15 or the body 16 in the rotational direction.
