Description

Technical Field

[0001] The present invention relates to a discharge head for discharging liquids, particularly pharmaceutical liquids or body care agents, as well as disinfectants and cleaning agents, and a liquid dispenser having such a discharge head. Background Technology

[0002] The discharge head according to the invention or of this type is used to discharge liquid from a liquid reservoir. For this purpose, the discharge head has a discharge channel and a discharge opening at the end of the discharge channel. For the purpose of discharge, it is preferable to press the discharge head down relative to the liquid reservoir. To prevent accidental discharge of liquid, particularly by children playing with the liquid dispenser, such a discharge head can be manually switched between a safety state and a release state, wherein discharge of liquid is prohibited in the safety state and discharge of liquid is enabled in the release state.

[0003] This type of discharge head has a housing with a discharge perforation. When the discharge opening and the discharge perforation are aligned and there is no baffle between them to prevent discharge, liquid discharged through the discharge opening can be discharged through the discharge perforation. To prevent discharge, this type of discharge head has one of two possible configurations: In the first configuration, the discharge head has an inner body with the discharge opening located therein, and the inner body is rotatable relative to the housing about a switch axis. The discharge opening is aligned with the discharge perforation of the housing in the open rotation position and is covered by the housing in the closed rotation position. Therefore, in such a design, the prevention or implementation of discharge depends on the relative rotational positions of the discharge opening and the discharge perforation. Alternatively, in the second configuration, this type of discharge head has a baffle body arranged inside the housing, which is rotatable relative to the housing about a switch axis. The baffle body has a blocking section arranged between the discharge opening and the discharge perforation in the housing in the closed rotation position and releases the discharge perforation in the open rotation position. In such a design, it is therefore stipulated that the discharge opening and discharge perforation are always aligned and oriented, and the prohibition or realization of the discharge depends on the location of the blocking section that can be positioned between them.

[0004] The described or similar type of discharge head is known from documents EP 2707311 B1 and US 8777061 B1. Summary of the Invention

[0005] The objective of this invention is to improve safety in preventing unintentional discharge for dispensers or discharge heads of this type, and in particular to ensure child protection features.

[0006] This task is accomplished by a discharge head, which, consistent with the discharge head of this type described at the beginning, has on one hand a housing with discharge perforations and on the other hand an inner body or baffle disposed inside the housing, the inner body or baffle being rotatable relative to the housing about a switch axis. It is irrelevant here that, during rotation, either the housing or the baffle or the inner body remains anti-rotational relative to the liquid reservoir, the discharge head being coupled to the liquid reservoir. The discharge opening is preferably configured as a discharge nozzle having a jet opening and / or a vortex mechanism, the discharge opening being preferably configured to be anti-rotational relative to the housing in a design with a baffle, and preferably located within the inner body and thus rotatable relative to the housing in a design with an inner body.

[0007] According to the present invention, a releasable snap-fit ​​coupling part is provided, by means of which the outer shell and the inner body or baffle body can be rotatably coupled in the closed rotational position, so that the open rotational position can only be reached again after a manual force is applied to the release surface of the releasable snap-fit ​​coupling part.

[0008] In the context of this invention, a "clamp coupling part" refers to a coupling mechanism that, when the inner body or baffle body rotates relative to the outer shell, suddenly occupies a coupling state upon reaching the closed rotation position through the mechanical unloading of a previously pre-tightened locking section. This coupling state cannot be released again simply by applying an opposite torque. When the discharge head is placed in this closed state, a preferred radial and / or axial force is applied to the release surface to elastically deflect the aforementioned locking section again, thereby enabling a subsequent reversal towards the open rotation position. Preferably, the clamp coupling part is configured such that an audible noise is generated upon reaching the closed rotation position and / or also upon reaching the open rotation position, allowing the user to detect the arrival of the corresponding terminal position audibly and, if necessary, tactilely.

[0009] According to the first configuration mentioned above, the discharge is achieved and prevented by the relative rotational property of the inner body and thus the discharge opening relative to the outer casing. Preferably, the inner body has an outer, surrounding shell section and a conduit section integrally connected thereto and extending into the internal region of the shell section, the conduit section being penetrated by the discharge channel. Not only are some designs in which the outer casing is kept anti-rotational relative to the liquid reservoir by means of a corresponding coupling mechanism while the inner body is rotatable relative to the liquid reservoir about the switch axis, but other designs in which the inner body is kept anti-rotational relative to the liquid reservoir by a coupling mechanism while the outer casing is rotatable relative to the liquid reservoir about the switch axis are also possible.

[0010] Here, the shell section is preferably a support for an element with a snap-fit ​​coupling located within the inner body. Furthermore, if the inner body is rotatable relative to the liquid reservoir, a gripping surface is preferably provided in the shell section to allow manual rotation of the inner body relative to the outer casing. The piping section extends into the internal region and, together with the discharge passage, surrounds the inlet piping leading to the discharge opening. The discharge opening can be integrally provided within the inner body or formed by a separate component as will be explained below.

[0011] When the housing is rotatable relative to the liquid reservoir, the housing preferably has at least one gripping surface for easy handling, the gripping surface in particular having a structured part, such as grooves.

[0012] Apart from the components directly associated with the snap-fit ​​coupling, the shell section is preferably designed to rotate only relative to the outer shell, while the conduit section is additionally designed to be depressable. For the purpose of limited mobility of the conduit section, a deformable connection region is preferably provided, which acts as a joint and is positioned between the shell section and the conduit section. The connection region is preferably formed of at least one thin-walled plastic bridge that elastically deforms upon depressurization.

[0013] The piping section is preferably configured for direct coupling to the valve tube of the accumulator and for this purpose has a liquid inlet aligned with the switch axis. The valve tube is preferably pushed into the liquid inlet. Axial movement of the liquid inlet causes the valve tube to be forced in, thereby causing the valve to open.

[0014] The piping section can be directly accessed from the outside, allowing it to be pressed down by a direct force applied to its upper side. However, the following design is advantageous, wherein the housing has a pressable operating handle, which is particularly in the form of an upper, pressable operating surface. This operating handle acts indirectly on the piping section. Therefore, the piping section is subjected to a downward force through the operating handle of the housing.

[0015] In the second configuration mentioned, a baffle body is provided, which is arranged between the discharge opening and the discharge perforation according to its rotational position relative to the housing and is able to prevent liquid discharge therefrom. In this design, the baffle body preferably has an outer surrounding shell section, which, unlike in the first configuration, cannot rotate with the discharge opening. Instead, in this configuration, the discharge opening is preferably configured to resist rotation relative to the housing and the discharge perforation disposed therein. Particularly preferred is that, for this purpose, the conduit section is integrally provided at the member forming the housing. This conduit section, similar to the conduit section mentioned above in the first configuration, is penetrated by a discharge channel that supplies liquid to the discharge opening. As already described, the discharge opening can be integrally defined in the conduit section or formed by a separate member.

[0016] In this second configuration, a depressable operating handle is preferably located on the housing. The piping section is preferably integrally connected to the operating handle. Preferably, this piping section also has a liquid inlet aligned with the switch axis and acting on the valve pipe of the liquid reservoir in the manner described above.

[0017] The snap-fit ​​coupling provided according to the invention is configured to couple the inner body (in the first configuration) or the baffle body (in the second configuration) to the outer casing (in the closed rotational position) in such a way that a pure torque load toward the open rotational position is insufficient to move the inner body away from the closed rotational position. To restore rotatability, an additional force must be applied to the release surface. The coupling in the closed position is particularly form-locked, preferably by a snap-fit ​​in a substantially radial direction along the reference switch axis. However, partial or fully axial snap-fit ​​is also possible in principle.

[0018] The locking mechanism is implemented in such a way that a segment, which elastically deflects from its initial position when moving toward the closed rotational position, engages with the recess or retaining perforation of the retaining profile when the aforementioned shape-locking is formed. The elastically deflected segment can be located on the outer casing and / or on the inner body or baffle body.

[0019] In a preferred design, the locking coupling portion is formed by a locking protrusion extending outward from the inner body or baffle body and capable of elastically deflecting radially inward, and a corresponding retaining perforation or retaining contour portion on the outer shell.

[0020] Here, the release surface is preferably formed through the end face of the aforementioned locking protrusion, thus eliminating the need for a separate release surface. Therefore, the locking protrusion is directly and manually loaded to disengage it from the aforementioned retaining recess or retaining perforation, thereby allowing it to immediately return to the open rotational position. However, it is also possible to construct the release surface separately from the locking protrusion and to apply force to it indirectly.

[0021] A particularly advantageous design specifies that the retaining perforation or retaining recess is formed by the discharge perforation itself, and the locking protrusion springs into the retaining perforation or retaining recess when the closed rotational position is reached. To move from the closed rotational position to the open rotational position, the user first presses the locking protrusion arranged in the discharge perforation, causing the locking protrusion to be pushed inward from the discharge perforation. Rotational movement toward the open rotational position is then possible.

[0022] However, the retaining perforation or retaining contour portion can also be provided separately from the discharge perforation, particularly on the side of the housing opposite to the discharge perforation.

[0023] Preferably, the locking protrusion is disposed at a radially deflectable surface segment, which is disposed on an adjacent segment of the inner body or the baffle body within a tangentially oriented deformation region.

[0024] In order for the locking protrusion to engage with the corresponding retaining perforation or retaining contour when reaching the closed rotation position, it must be pre-tensioned elastically. One feasible approach is to keep the locking protrusion elastically pre-tensioned at all times when it is not engaged in the closed rotation position. However, this carries the risk that the elasticity will decrease over time due to relaxation. Therefore, it is preferable that the locking protrusion is at least partially relaxed in the open rotation position and tensioned before reaching the closed rotation position during rotational movement toward the closed rotation position. To achieve this, a guide ramp is preferably provided on the inner side of the housing, or on the outer side of the inner body or baffle body, and / or at the locking protrusion, which, when the inner body or baffle body moves relative to the housing toward the closed rotation position, elastically deflects the locking protrusion, particularly radially inward or outward, by means of the guide ramp.

[0025] Preferably, the safety mechanism of the outer casing at the inner body or the baffle body is provided not only in the closed rotational position but also in the open position. However, the safety mechanism cannot be overcome by rotational movement alone in the closed rotational position, while in the open rotational position, it is preferably overcome by rotational movement that overcomes the increased resistance torque. For this purpose, it is preferable that the baffle body or inner body and the outer casing have a retaining device that works together to provide safety for the rotational position in the open rotational position. The aforementioned locking protrusion is also part of the snap-fit ​​coupling portion, and it is preferably also part of these retaining devices. Particularly preferably, upon reaching the open rotational position, the locking protrusion springs into the recess and generates an audible noise, which is interpreted by the user as confirmation of reaching the open rotational position.

[0026] The described safety feature in the open rotation position reduces the risk of erroneous discharge, which could occur if the outer casing and inner / baffle body are unintentionally positioned a few degrees away from the open rotation position.

[0027] The two configurations mentioned above, with an inner body or with a baffle body, result in the discharge opening being visible through the discharge perforation of the outer casing in the open rotation position and not visible in the closed rotation position. This is either because the discharge opening is offset relative to the discharge perforation in the closed rotation position (the first configuration with an inner body), or because the blocking section of the baffle body is arranged between the discharge opening and the discharge perforation (the second configuration with a baffle body).

[0028] This is also preferably used to enable users to quickly identify the exact rotational position of the discharge head through color coding. For this purpose, it is preferable that the discharge opening is formed by a discharge opening member, such as, in particular, a nozzle member, which has a different color scheme from the inner body or baffle body. Therefore, it is particularly possible to design the discharge opening member to be green and the inner body or baffle body to be red. In the open rotational position, the discharge opening member is visible through the discharge perforation and is indicated by its green color as it is ready to discharge. In the closed rotational position, only the inner body or baffle body is visible through the discharge perforation, and this inner body or baffle body is red to indicate that the discharge head is currently blocked.

[0029] For the discharge head according to the invention, the discharge in the closed rotation position is prohibited at least by the following means: the liquid discharged through the discharge opening cannot escape through the discharge perforation, either because the discharge opening and the discharge perforation are not aligned (first configuration) or because a baffle is arranged between the two (second configuration).

[0030] However, it is preferred that rotation toward the closed rotation position is also prohibited from discharge in an additional manner.

[0031] Therefore, it is particularly preferable that the inner body, or baffle body, is coordinated with the outer shell in such a way that the downward pressure of the operating handle of the outer shell is locked in the closed rotation position. This can be achieved, in particular, by having the piping section positioned above the locking section in the closed rotation position, the locking section acting as a stop and thereby preventing the downward pressure of the piping section.

[0032] Another way to prohibit or obstruct the discharge in the closed rotation position is to have the housing have a free area on the side opposite the discharge perforation for lateral access to the operating handle, and the inner body, or baffle body, also has a free area for lateral access to the operating handle. In the open rotation position, these free areas overlap, thereby creating lateral accessibility to the operating handle and facilitating downward pressure with a finger positioned laterally on the discharge head. Conversely, in the closed rotation position, the free areas are offset relative to each other, thereby preventing lateral accessibility. Even if this alone does not reliably prohibit operation, it demonstrates to the user that discharge in the closed rotation position is not permissible.

[0033] As described, the inner body, or baffle, is rotated about the switch axis relative to the housing for replacement purposes. While it is not important to which component remains anti-rotational relative to the liquid reservoir for the described operation, it is considered preferable that the housing is form-locked or force-locked anti-rotationally fixed to the liquid reservoir, so that the liquid reservoir can be held in place on the one hand, and the inner body, or baffle, can be rotated relative to the liquid reservoir on the other hand for rotation purposes.

[0034] Preferably, manual force application to the inner body or baffle body along the rotation direction is performed by means of a gripping surface disposed thereon, which is designed in particular to facilitate hand gripping through surface structuring. When the locking protrusion engages with the retaining profile, it is advantageous to place the gripping surface directly at the locking protrusion. However, if a retaining perforation is provided, and the locking protrusion engages with the retaining perforation as specified, then the gripping surface for rotating the inner body or baffle body is preferably disposed separately from the locking protrusion and / or the release surface, and preferably opposite the release surface. This opposite arrangement makes it particularly difficult for a child to simultaneously apply force to both the release surface and the gripping surface to transition to the open rotation position.

[0035] In addition to the discharge head itself, the present invention also relates to a liquid dispenser having such a discharge head. This liquid dispenser, in addition to having a discharge head, also has a liquid reservoir, at which the discharge head is fixed.

[0036] Such dispensers are particularly capable of being constructed to dispense pharmaceutical liquids or body care products, as well as disinfectants and cleaning agents, and have a liquid reservoir filled with such liquids when in a ready-to-use state.

[0037] Particularly preferred is that the liquid reservoir is configured as an accumulator, meaning it is already pressurized, for example, by compressed air or propellant, before being put into operation. Particularly preferred is that the liquid reservoir has an outlet valve that can be operated by means of an internal body or a piping section disposed in the outer casing. For this purpose, the outlet valve preferably has a depressurizable valve tube that opens the outlet valve by depressurization. This valve tube is preferably inserted into the fluid inlet described above in the piping section and can be depressurized therethrough.

[0038] The described discharge head makes accidental discharge of liquid difficult due to its safety shut-off rotation position, especially when a dispenser with such a discharge head comes into the hands of a child. However, such child protection is only sufficiently safe if the discharge head as a whole is also difficult to remove from the liquid storage device.

[0039] Not only is a design in which the outer casing is connected to the liquid reservoir in a rotation-resistant manner possible, but such a design is also possible in which the inner body is connected to the liquid reservoir in a rotation-resistant manner. "Rotation-resistant" in this context means that the connection is maintained in a form-locked or force-locked manner in terms of rotation, and that the resistance to rotation of the outer casing or inner body relative to the liquid reservoir is higher than the resistance of a component that is rotatable relative to the outer casing or inner body. Therefore, it is preferably specified that the discharge head and, in particular, its casing, are connected to the liquid reservoir such that a separation force of 100 Newtons is insufficient to pull the discharge head from the liquid reservoir. A locking connection, in particular, can be involved to ensure this. It is also particularly suitable that the connection is designed so that it cannot be released without damage. In such a case, separation of the discharge head and the liquid reservoir can only be achieved destructively, in particular by bending or breaking the retaining section of the discharge head. This can typically only be achieved by using a force that is at least impossible for a child to apply. Attached Figure Description

[0048] Figures 17 to 22 A fourth variant of the discharge head is shown. Detailed Implementation

[0049] Figure 1 The liquid dispenser 100 according to the invention is shown in general view.

[0050] The liquid dispenser 100 has a liquid reservoir 102, which is configured as an accumulator, storing pharmaceutical liquids or body care products under pressure. The liquid reservoir 102 is closed by a crimp cap. The crimp cap has an outlet valve 104 with a valve tube 106. This valve tube 106 is referenced... Figure 1Pressing down opens the outlet valve 104, allowing liquid to flow through the valve tube 106 into the discharge head 10, which is fixed to the crimp cover by means of a locking connection.

[0051] The discharge head 10 has a liquid inlet 16, which is pushed onto the valve tube 106. The discharge channel 12 extends from the liquid inlet 16 to the discharge opening 14, which is preferably designed as a jet opening and can be provided with a front vortex chamber to induce vortices in the outflowing fluid and thus generate a jet stream.

[0052] The pipe section 44 of the discharge head 10 can be pressed down by manually applying force from top to bottom. As a result, the liquid inlet is also pressed down, which in turn squeezes the valve pipe 106 downward and thereby opens the outlet valve 104.

[0053] The other accompanying figures illustrate this in more detail. Figure 1 The configuration of the discharge head 10 is shown only as an example.

[0054] exist Figures 2 to 7D In the design, the discharge head 10 has an outer shell component 20 and an inner body 40 therein. An additional discharge opening component 90 is provided, which is inserted into a corresponding empty portion of the inner body 40.

[0055] The outer casing member 20 is configured to be locked onto the liquid reservoir 102. A coupling mechanism for this purpose is provided on the inner side of the coupling flange 21, which remains in a fixed position relative to the liquid reservoir 102 during operation and can only be released from the liquid reservoir under strong tensile loading, and preferably cannot be released from the liquid reservoir without damage. An incompletely encircling outer cover section 23 extends upward from the coupling flange 21, through which the discharge perforation 22 passes. An operating handle 30 is integrally formed on the inner side of the outer cover section 23, which is secured to the outer cover section 23 only by means of a narrow bridging member and can thus be elastically pressed down relative to the outer cover section 23.

[0056] The aforementioned inner body 40 is fitted into the outer shell member 20. This inner body 40 has an outer, surrounding shell section 42 and a conduit section 44 integrally connected thereto. The conduit section 44 contains the described components for the liquid inlet 16, the discharge passage 12, and a receiving portion for the discharge opening member 90. The conduit section 44 is integrally formed into a partial section that can be pressed down relative to the section surrounding the shell section 42 by elastic deformation, thereby transmitting the force acting on the operating handle 30 to the conduit section 44, and thus enabling the conduit section 44 to press down the valve pipe 106 to open the valve.

[0057] Furthermore, a locking protrusion 66 is provided at the shell section 42 of the inner body 40. This locking protrusion, via a notch, can also deflect relative to an adjacent portion of the shell section 42. This locking protrusion 66 has an end face 62, which, as will be described below, also represents a release surface 62. This release surface 62 has an inlet ramp 64 on one side. Additionally, the shell section 42 has a gripping surface 48 approximately opposite the locking protrusion 66; the use of this gripping surface will be explained below.

[0058] exist Figures 2 to 5 In the assembled state shown, the inner body 40 is inserted into the outer casing 20 from below and is rotatable within the outer casing about the switch axis 2. Except for sections 66, 44, and 30 located at these two components in a limited manner, the outer casing 20 and the inner body 40 are movable relative to each other in a manner capable of pure rotation about the switch axis 2. They have corresponding guide surfaces for this purpose.

[0059] exist Figure 2 and Figure 3 The diagram shows the closed state of the discharge head 10. In this closed state, the inner body 40 and the outer shell member 20 are in a closed rotational position relative to each other. In this closed rotational position, the locking protrusion 66 is arranged within the discharge through-hole 22, which thereby forms a retaining through-hole 68 for the snap-fit ​​coupling portion 60. The same rotational position of the inner body 40 relative to the outer shell member 20 is shown in the diagram. Figure 6 As can be seen, in this position, the discharge opening 14 is not aligned with the discharge perforation 22, thus making discharge impossible. Furthermore, discharge in this position becomes difficult because the downward pressure of the operating handle 30 is blocked by the locking section 41 of the inner body 40. Additionally, the cut-off free area 46 in the inner body 40... Figure 2 and Figure 3In the closed state, it is offset by 90° relative to the corresponding free area 26 of the outer casing component 20, so that it is obvious to the user that no operation should be performed in this rotational position.

[0060] In order to place the discharge head in the open position—in which discharge can subsequently be made by operating the operating handle 30—the inner body 40 must be rotated counterclockwise by approximately 90° relative to the outer casing member 20. However, this is only possible if, for this purpose, the locking protrusion 66 is disengaged from the discharge opening 22 by direct, manual force applied to the release surface 62 of the locking protrusion. This is in Figure 3 Arrows are used to indicate this. Therefore, it is stipulated that... (refer to...) Figure 2 The user presses the locking protrusion 66 radially inward and performs the action in this state. Figure 5 The relative rotation is indicated by the arrow. A gripping surface 48, already described, is provided for this relative rotation and is moved counter-clockwise by the user. Thus, when the discharge opening 14 is positioned aligned with the discharge perforation 22, the locking protrusion 66 is removed from the discharge perforation 22. Figure 4 and Figure 5 The open state thus obtained is shown. In this state, liquid can be discharged by pressing down the operating handle 30. This pressing down also indirectly causes the pipe section 44 of the inner body 40 to be pressed down, and thus causes the valve pipe 106 to be pressed down.

[0061] To return the discharge head 10 to its locked position after use, rotate the gripping surface 48 clockwise. During the transition, the locking protrusion 66 is radially pressed inward through the inside of the housing member 20 by means of its guide ramp 64 until it re-engages in the discharge perforation 22 within the area of ​​the discharge perforation 22. This re-engages the device. Figure 2 and Figure 3 The initial state of the insurance.

[0062] With the help of Figures 7A to 7D The cross-sectional view further illustrates the relationship between... Figure 2 and Figure 3 Corresponding Figure 7A Close the rotation position to the Figure 4 and Figure 5 Corresponding Figure 7D The transition from the open rotation position. Starting from the closed rotation position, manually press the locking protrusion 66 inward from the discharge perforation 22, as if through... Figure 7B As indicated by the arrow in the diagram. While still manually pressing the locking protrusion 66 inward, the user begins to rotate by applying force to the gripping surface 48, as shown in... Figure 7CAs indicated in the diagram, when the open rotation position is reached, the locking protrusion 66 engages with a recess on the inner side of the housing member 20. This causes a noise and signals to the user that the rotational movement has been performed sufficiently. Furthermore, the engagement of the locking protrusion 66 with the recess 28 also ensures that the open position is not easily disengaged.

[0063] Figures 8 to 12 The design scheme is largely similar to the previous embodiment. The differences are explained below. Other applicable provisions are as follows: Figures 2 to 7D The characteristics described.

[0064] according to Figures 8 to 12 The discharge head 10 also has a housing member 20 and an inner body 40. However, unlike the previous design, there is no locking protrusion extending into the discharge perforation 22 in the closed state. Instead, a section—where the gripping surface 48 is provided—forms both the locking protrusion 66 and its end face 62. To form a snap-fit ​​coupling portion 60 with this section, a retaining profile portion 70 is provided in the free region 26 of the housing member 20. Figure 8 and Figure 9 In the closed position of the safety mechanism, the locking protrusion 66 is positioned radially outward so far that rotational movement toward the open rotational position is prevented by the retaining profile portion 70's stack portion 72. Only when the locking protrusion 66 is pressed in by applying a radial force to the gripping surface 48 can an additional tangential force be applied to induce rotation from the open position. Figure 8 and Figure 9 From the closed state to Figure 10 and Figure 11 Rotational motion in the open state. Figure 9 and Figure 11 The arrows in the diagram indicate pressing and rotation.

[0065] Reverse movement to the safety state is facilitated by the guide ramp 74, which in this case is not located at the locking protrusion 66, but at the stack 72.

[0066] In this second design, the safety features are guaranteed almost exactly the same as in the first design, provided that measures are taken to prevent accidental opening, for example, in luggage. However, regarding child protection, Figures 2 to 7D The embodiment is more suitable because reaching the open rotational position is difficult for a child due to the simultaneous force applied to the locking protrusion 66 and the gripping surface 48, which are arranged opposite each other therein. However, regarding Figures 8 to 12In some embodiments, when the retaining contour portion 70 and the locking protrusion 66 are properly designed, especially when pressing the gripping surface into place for the purpose of releasing the snap connection requires an operating force of more than 20 N (Newtons), manipulation by a child becomes significantly more difficult.

[0067] Figures 13 to 16 An alternative construction is shown. Consistent with the aforementioned embodiments, a housing member 20 is also provided here, which has a discharge perforation 22 through which liquid previously discharged through the subsequent discharge opening 14 can be discharged. However, unlike the previously mentioned embodiments, in... Figures 13 to 16 In this embodiment, instead of an inner body with piping sections, a baffle body 50 is provided, which is coupled to the outer housing member 20 in a manner similar to that of the inner body described above, so that it can rotate relative to the outer housing member 20 about the switch axis 2.

[0068] In this design, the pipe section with the discharge opening 14 is not configured to rotate relative to the housing member 20, but rather is configured such that the discharge opening 14 is always aligned with the discharge perforation 22. However, to prevent discharge, in Figure 13 and Figure 14 In the closed rotation position, the baffle body 50 closes the discharge perforation 22 by means of the blocking section 52. For this purpose, a gap is provided between the inside of the discharge perforation 22 and the discharge opening 14.

[0069] The baffle body 50 is in conjunction with Figures 8 to 12 In the same manner as in the embodiment, the inner body 40 is fixed to the outer shell member 20 in the closed rotation position, that is, by means of the locking protrusion 66, the end face 62 of which forms a gripping surface 48.

[0070] In order to discharge the head 10 from Figure 12 and Figure 13 Its closed rotation position is placed into Figure 14 and Figure 15 In its open rotational position, the locking protrusion 66 must be moved again by applying a radial force to the release surface 62 of the locking protrusion, so that the locking protrusion 66 can subsequently pass beside the stack 72 of the retaining profile portion 70. Figure 13 The arrow in the diagram illustrates this. Through this movement, the recess 56 of the baffle body 50 reaches between the discharge opening 14 and the discharge perforation 22, thereby allowing discharge to be made through this perforation in the open rotation position.

[0071] Figures 17 to 22 Another embodiment of the discharge head 10 according to the invention is shown. This is similar to... Figures 2 to 7D The design scheme is consistent with the aforementioned design scheme, wherein the discharge head has a housing component 20 and an inner body 40 therein.

[0072] Compared to Figures 2 to 7D The first major difference in the design schemes is that, Figures 17 to 22 In the design, the outer shell component 20 is designed to rotate, while the inner body 40 is simultaneously the portion of the discharge head 10 that is locked to the liquid reservoir 102. The inner body 40 has, for this purpose, a locking device 49 for securing it to the liquid reservoir 102, as shown in… Figure 18 As can be seen in the image.

[0073] Compared to Figures 2 to 7D Another difference in the aforementioned design is that the angle between the discharge opening 14 and the release surface 62 is not 90°, but less than 90°, approximately 45° in this case. This allows the discharge head 10 to move effortlessly between the secured and released states. Since the inner body 40 is fixed to the liquid reservoir 102, the necessary relative rotational movement can be achieved by gripping the outer casing member 20 and the liquid reservoir 102 and applying the necessary torque relative to each other. To facilitate this, at least one gripping surface 27, in this case two opposing gripping surfaces 27, is provided on the outer casing member 20.

[0074] This achieves exceptionally good maneuverability. The user can grasp the outer surface of the housing member 20 with one hand in the area of ​​the gripping surface 27 and press the release surface 62 in with the same hand, as by... Figure 19 and Figure 20 As indicated by the arrow, this allows for subsequent rotational movement relative to the liquid reservoir 102 and the inner body 40 and its outer surface 47. Thus, the user inserts the discharge head from... Figure 19 and Figure 20 The insurance status has been changed to Figure 21 and Figure 22 It is currently in use.

[0075] In use, and then able to Figure 21 The operating handle 30 of the outer casing component 20 is pressed down in the manner indicated by the arrow. As a result, the piping section 44 of the inner body 40 is also indirectly pressed down, in which elastic deformation occurs, because the components surrounding the inner body 40, especially its outer surface 47 and the locking device 49, are not pressed down together.
