Description

The present invention relates to a dispensing device for dispensing a fluid and a dispenser for dispensing a fluid.

In particular, the present invention relates to a dispenser for the storage and discharge of cleaning agents or pharmaceutical or cosmetic fluids, in particular liquids. A fluid can be accommodated in a container of the dispenser, which can be conveyed out of the container by means of a dispensing device attached to the container and can be dispensed from the dispenser by means of the dispensing device. The fluid can be delivered in various delivery forms, for example as a spray or aerosol or as a foam.

In principle, however, the following invention is versatile and can be used in any technical field in which a fluid is dispensed from a container.

The WO 2015/106868 A1 discloses a dispenser for liquids with a liquid reservoir in which the liquid is stored before discharge, with an outlet channel through which the liquid can be released into an environment, and with a pump chamber that can be volumetrically reduced by means of an operating handle. An inlet valve of the pump chamber is formed by a ring-shaped sealing lip, which is prestressed against a counter surface and thus lies sealingly against the counter surface.

The US 2012/0024904 A1 discloses a liquid dispenser with a pump device which is formed by a flexible bellows and with which liquid can be pumped out of a container of the dispenser. The pump device is actuated or the bellows is compressed by pressing down an axially movable actuation handle, which also has an outlet opening for the fluid. An inlet and outlet valve open automatically.

The US 5,114,052 concerns a hand-operated trigger pump. An operating lever is formed integrally with a main body of a spray cap by a film hinge. The operating lever engages with two button-like guide elements Guide rails arranged on a bellows form-fittingly, so that the bellows can be compressed with the actuating lever for fluid delivery.

The US 3,840,157 relates to a hand-operated spray device for dispensing a liquid with an operating lever. A cylinder-piston arrangement for conveying or dispensing the liquid can be actuated by means of the actuating lever. When actuated, the cylinder-piston arrangement is lifted from an associated seat so that air can pass between the seat and the cylinder-piston arrangement into the container.

The DE 198 03 693 A1 relates to a spray pump with a flexible bellows which is actuated by an operating lever. The bellows is formed in one piece with a base. A valve element of a valve is formed by a ball.

The DE 44 11 031 A1 relates to a pump that can be operated with a hand lever and is formed by a cylinder-piston arrangement.

The US 4,278,187 A1 relates to a pump arrangement with a securing mechanism for securing an operating lever. The operating lever has a hook that is hooked into a lip to secure the operating lever.

The US 2006/0113329 A1 relates to a dispenser that has a locking sleeve. The locking sleeve can be rotated between a first position in which operation of the dispenser is prevented and a second position in which operation of the dispenser is permitted.

The US 5,303,867 A relates to a lever-operated dispensing device for dispensing fluids, in particular as a spray. A flexible pump is preferably designed as a bellows and oriented in the delivery direction.

The US 6,279,784 B1 relates to a lever-operated pump spray head. The spray head includes a component with a collapsible fluid chamber portion and an expandable spring portion. The actuating lever is coupled to this component, with pivoting of the lever causing the spring section to stretch and the fluid chamber section to compress.

The JP 2007 244937 A relates to a pump dispenser with an elastically deformable dome and a lever. A lower end of the dome is in a dome base fitted. When the lever is actuated, the dome base is pushed upward by the lever so that the dome deforms to release fluid within it.

It is an object of the present invention to enable a simple, reliable and/or safe function and/or a simple structure of a dispensing device or a dispenser and/or an operation and/or an exit of fluid during the transport of a dispenser in a simple manner or to prevent it in a cost-effective way.

The above task is solved by a dispensing device according to claim 1 or by a dispenser according to claim 12. Advantageous further developments are the subject of the subclaims.

A dispensing device according to the proposal is designed to dispense a fluid, in particular contained in an assigned container and/or connected to the dispensing device.

The dispensing device has a pump device with a flexible bellows for conveying the fluid. In particular, the fluid can be conveyed into the bellows by an expansion of the bellows or a negative pressure created by the expansion and can be released from the bellows by compressing the bellows.

The pump device has a base connected to the bellows on an inlet side of the bellows. The base has or forms a supply channel for the fluid.

According to the present invention, the dispensing device has an operating lever for actuating the pumping device or dispensing device. A base element of the base of the pump device has or forms an actuation surface designed as a counter surface for the actuation lever. This is conducive to simple and reliable actuation of the pumping device or delivery device and/or compression of the bellows.

The combination of the actuating lever and the pump device with a flexible bellows has proven to be particularly advantageous in a synergistic manner.

Preferably, a line of the base that forms or has the feed channel is held sealingly in a seat or a guide. The line preferably has a particularly conical taper on the outside, so that the line is lifted off the seat or the guide when the dispensing device is actuated or the base moves axially, and in this way a ventilation gap is created between the guide and the line for ventilation of a container is formed. This enables easy ventilation of the container with a simple construction of the dispensing device. In particular, an additional ventilation valve or the like can be dispensed with.

Preferably, the dispensing device has an inlet valve with a valve element for sealingly covering an end opening of the feed channel. The valve element is preferably formed in one piece with the bellows and held via one or more flexible arms of the bellows. This is conducive to reliable sealing of the feed channel and/or allows a simple structure with few parts.

The operating lever has a manually operable operating arm.

The actuating arm can preferably be secured against (unwanted) actuation, in particular in a securing position, by folding it down and/or on a spray head of the dispensing device. In this way, it can be prevented that fluid accidentally escapes from the dispenser during the delivery or transport of a dispenser that is filled with a liquid and has a dispensing device according to the proposal. In particular, no additional transport security or one separate from the dispenser or the dispensing device needs to be provided or attached to the dispensing device or the dispenser. This enables cost-effective production and/or delivery, since in particular there is no need for additional fuses or security parts. In particular, the proposed solution is also particularly environmentally friendly because less waste is produced.

Preferably, the actuating lever or actuating arm can be secured against actuation in a securing position and, in particular with the actuating lever in the securing position, an outlet opening of the dispensing device can be closed. In this way, double security can be achieved or an unwanted leakage of fluid can be effectively prevented.

Preferably, the actuating lever or actuating arm can be secured or locked against actuation by a movable locking element. The locking element is preferably arranged or can be arranged between the actuating lever or actuating arm and a housing of the dispensing device, in particular so that the locking element blocks the actuating lever or actuating arm against unwanted actuation and/or the position of the actuating lever is fixed relative to the housing. In this way, the actuating lever can be reliably secured or locked in a simple manner.

The actuating lever is designed in particular to move the base axially and/or to compress the bellows. This is conducive to simple and reliable operation.

The actuating lever is pivotally mounted on the dispensing device. This is conducive to simple construction and/or cost-effective production.

The operating lever has or is formed by the operating arm for manual operation and a lifting arm for moving the base. The lifting arm is preferably arranged or can be arranged transversely, in particular at right angles, to the actuating arm, at least in a use position of the actuating lever. The actuating arm is preferably movably connected to the lifting arm by a film hinge. This allows the actuating arm to be folded away from the lifting arm in a simple and cost-effective manner.

Preferably, the actuating arm can be fixed in a position of use on the lifting arm, in particular by means of a latching connection. This enables simple and reliable operation or actuation of the foldable actuation arm.

A closure of the dispensing head or the outlet opening is preferably designed to secure the actuating lever or actuating arm against actuation - at least in a closed position. This enables transport security in a simple manner without additional components.

The actuating lever or actuating arm can preferably be secured in a form-fitting and/or latching manner with the closure of the dispensing head or the outlet opening. This is conducive to reliable backup.

According to a further aspect, the present invention relates to a dispenser for dispensing a fluid with the dispensing device and a container. The fluid can be conveyed out of the container using the dispensing device and can be dispensed from the dispenser by means of the dispensing device.

The dispensing head 14 preferably has a fastening part 14A for connecting or fastening the pump device 4 or the bellows 5 to/on the dispensing head 14. The fastening part 14A is preferably a separate or separately manufactured component from the dispensing head 14. However, other solutions are also possible here.

The fastening part 14A preferably has one or more openings 14B for the fluid F, which are preferably designed like slots.

The dispensing head 14 preferably has or forms an outlet channel 15 which runs in particular transversely or perpendicular to the axis L. The outlet channel 15 is preferably fluidly connected or connectable to the outlet 5B, in particular through the opening(s) 14B in the fastening part 14A, and opens into an outlet opening 16. The fluid F can preferably flow via the outlet channel 15 and the outlet opening 16 emerge from the dispensing head 14 or are dispensed by the dispenser 1 or the dispensing device 2.

The fluid F is dispensed from the dispenser 1 or the dispensing device 2 preferably by actuating the pump device 4 or the bellows 5, in particular by means of an actuating lever 21. The actuating lever 21 will be discussed in more detail later.

When using the dispenser 1 for the first time, it may be necessary to first operate the pump device 4 a few times in order to remove air from the pump device 4 and/or to introduce fluid F from the container 3 into the dispensing device 2 or the pump device 4 for the first time. to promote the bellows 5.

When the pump device 4 is actuated, the fluid F preferably passes from the container 3 via the feed channel 11 or the line 12 and/or the riser line 13 into the delivery device 2 or the pump device 4 or the bellows 5.

The inlet valve 7 is preferably designed in such a way that it opens when the fluid F is delivered with the pump device 4 or when the fluid pressure is present on the supply channel side and thus enables the fluid F to be delivered from the supply channel 11 through the inlet valve 7 into the interior 5C of the bellows 5 .

The bellows 5 is preferably in an unactuated position or rest position, which is in Fig. 1 is shown, and in an actuated or compressed position, which is shown in Fig. 3 is shown, can be positioned or arranged or deformed into these positions.

The bellows 5 is preferably designed to automatically assume or return to the rest position, in particular by elastic resetting, if no force deforming the bellows 5 from the rest position acts on the bellows 5. Preferably, the bellows 5 is compressed axially or along the axis L in the actuated position. The compression of the bellows 5 takes place in particular axially or parallel to the axis L and/or by pushing or folding the corrugated side wall 6 together.

The bellows 5 is preferably held or fastened in a stationary or immovable manner on the outlet side, in particular by or on the dispensing head 14. Preferably, the outlet 5B and/or the dispensing head 14 change their (axial) position relative to the housing 2A and/or the container 3 does not occur when the bellows 5 is compressed or deformed or when the dispensing device 2 or the dispenser 1 is actuated.

The inlet 5A and/or the base 9 preferably change their (axial) position relative to the housing 2A and/or the container 3 at a time Compression or deformation of the bellows 5 or when the dispensing device 2 or the dispenser 1 is actuated.

Preferably, when or by actuating the pump device 4, an axial movement of the base 9, in particular upwards or in the direction of the bellows 5, and / or a compression or reduction in volume of the bellows 5 takes place.

The compression or volume reduction of the bellows 5 causes an increased pressure of the fluid F located in the interior 5C of the bellows 5, so that the fluid F is present at the outlet valve 8 at an increased pressure, through which the outlet valve 8 preferably opens.

The compression of the bellows 5 therefore preferably causes the fluid F to enter the outlet channel 15 through the outlet valve 8 and to leave it via the outlet opening 16 and thus to be discharged from or by the dispensing device 2.

When the operation of the pump device 4 is ended or no compressive force (any longer) acts on the bellows 5, the bellows 5 preferably returns to the rest position, in particular by elastic resetting.

Preferably, the expansion of the bellows 5 from the compressed or actuated position into the rest position reduces the pressure in the interior 5C of the bellows or creates a negative pressure in the bellows 5 or its interior 5C during the expansion, through which preferably the outlet valve 8 closes. Furthermore, the inlet valve 7 is preferably opened by the negative pressure, so that fluid F present in the supply channel 11 at the inlet valve 7 flows or can flow through the inlet valve 7 into the interior 5C of the bellows 5.

The inlet valve 7 is preferably formed by the line 12 and the bellows 5. In particular, the inlet valve 7 or the bellows 5 has a valve element 7A formed in one piece with the bellows 5. The valve element 7A preferably closes

The arms 7B preferably lie in a plane running transversely, in particular perpendicularly, to the axis L.

Preferably one end of an arm 7B is arranged on the valve element 7A and/or one end of an arm 7B is arranged on the fastening section 5D.

The arms 7B can project radially or tangentially from or extend to the valve element 7A.

Preferably, the arms 7B are curved or the arms 7B run at least essentially radially at their ends and in a central section or spaced from the ends in a circular arc-like manner and/or coaxially to the axis L, in particular parallel to the outer contour of the valve element 7A and/or to the inner edge of the attachment section 5D. As a result, the curved arms 7B are extended compared to radially extending or arranged arms 7B, so that opening the inlet valve 7 is easier.

The outlet valve 8 is preferably formed by a particularly ring-like sealing lip 8A, which - at least in the closed state of the outlet valve 8 - rests sealingly on a counter surface 8B, which is preferably designed like a ring and/or is arranged coaxially to the axis L, and is in particular biased against the counter surface 8B . In an open position of the outlet valve 8, the sealing lip 8A is lifted off the counter surface 8B, so that a gap is formed between the sealing lip 8A and the counter surface 8B, through which the fluid F emerges from the interior 5C of the bellows 5 and into the outlet channel 15 can occur.

Preferably, the fastening part 14A has or forms the counter surface 8B.

Preferably, the dispenser 1 or the dispensing device 2 is designed in such a way that when the pump device 4 is actuated, the container 3 is automatically ventilated, so that during or through the conveying and/or dispensing of the fluid F from the Container 3 no (too high) negative pressure is created in the dispenser 1 or the container 3. Such a negative pressure could lead to a deformation of the container 3 and/or prevent or make it more difficult (further) delivery of the fluid F from the container 3, which is undesirable.

The dispenser 1 or the dispensing device 2 is preferably designed so that when the pump device 4 is actuated, in particular when the bellows 5 or the base 9 moves axially, a ventilation gap 17 is formed, through which ventilation of the container 3 is made possible or . he follows.

The ventilation gap 17 is formed in particular by the line 12 being lifted or spaced apart from the guide 18 during an axial movement.

In particular, the ventilation gap 17 is formed between the guide 18 and the line 12 when the pump device 4 is actuated, in particular when the bellows 5 is compressed or is deformed from the rest position into the compressed position and/or when the base 9 moves axially upwards or is moved in the direction of the dispensing head 14.

The ventilation gap 17 is preferably formed during the axial movement of the base 9 or line 12 in that the line 12 has or forms a (conically) tapered section or a particularly conical taper 19 on the outside.

The taper 19 is preferably arranged in the area of the guide 18 on the line 12.

Due to the taper 19, the outer diameter of the line 12 is preferably changed, in particular reduced downwards or with increasing distance from the bellows 5.

Due to the taper 19, the distance between the line 12 or taper 19 and the guide 18 is changed, in particular increased, in particular when the base 9 or line 12 moves axially (in the direction of the bellows 5 or upwards), so that the ventilation gap 17 is formed.

The guide 18 preferably forms and/or has a seat and/or stop 18A for the line 12. The stop 18A is preferably designed to prevent and/or block an axial movement of the base 9 or line 12 downwards or in the direction of the container 3. The stop 18A is preferably designed as a projection projecting radially inwards from the guide 18 or its inside, in particular as an annular bead.

The connecting part 20 preferably forms a part or section of the housing 2A or the housing 2A has the connecting part 20.

The connecting part 20 preferably has the guide 18 or forms it.

Preferably, the dispensing device 2 is attached to the container 3 with or through the connecting part 20. The connecting part 20 can, for example, be screwed onto the container 3 and/or connected to the container 3 in a latching manner. However, other solutions are also possible here.

The connecting part 20 is preferably arranged axially between the container 3 and the bellows 5 and/or the dispensing head 14.

The dispenser 1 or the dispensing device 2 or the housing 2A preferably has a housing part 2B. Preferably, the housing part 2B forms a part or section of the housing 2A. The housing part 2B is preferably at least essentially sleeve- or ring-like or hollow cylindrical and/or arranged coaxially to the axis L.

The housing part 2B is preferably arranged (axially) between the connecting part 20 and the dispensing head 14 or connects them to one another.

The bellows 5 is preferably arranged within the housing part 2B and/or coaxially therewith.

The dispensing head 14, the fastening part 14A, the housing part 2B and/or the connecting part 20 can each be connected to one another in a force-fitting, form-fitting and/or fluid manner, in particular locked, screwed, glued, welded or molded on. It is also possible for one or more of the parts 14, 14A, 2B, 20 mentioned to be formed in one piece or to form different sections of a single component.

The dispensing device 2 or pumping device 4 has an operating lever 21 for manual actuation of the dispensing device 2 or the pumping device 4. Preferably, the pumping device 4 is actuated or the bellows 5 is compressed to deliver the fluid F (exclusively) by (manually) actuating the actuating lever 21 by a user (not shown).

At this point it should be noted that in embodiments that do not fall within the scope of protection of the claims, the pump device 4 or delivery device 2 also can be realized without the actuating lever 21 or can be actuated in a different way than with the actuating lever 21 described in more detail below. Solutions are conceivable here, for example, in which the pumping device 4 is actuated or the bellows 5 is compressed by an axial movement or a dispensing head is pressed down, for example in FIG WO 2015/106868 A1 or the US 2012/0024904 A1 described.

It is also possible that in embodiments that do not fall within the scope of protection of the claims, the properties and features of the actuating lever 21 described below, in particular with regard to securing against actuation, are carried out independently of the implementation of the pump device 4 by or with a flexible bellows . For example, instead of the bellows 5, a cylinder-piston arrangement is also conceivable, for example similar to that in the US 3,840,157 cylinder-piston arrangement described.

The actuating lever 21 is pivotably arranged or mounted on the dispensing device 2, in particular the housing 2A.

The actuating lever 21 has an actuating arm 22 and a lifting arm 23 coupled to the actuating arm 22 or is formed by them.

The actuating arm 22 is preferably arranged outside the housing 2A or housing part 2B. The lifting arm 23 is preferably arranged at least in sections or predominantly within the housing 2A or housing part 2B or protrudes into it.

The housing 2A or housing part 2B preferably has a recess or opening through which the actuating lever 21 or lifting arm 23 can be carried out or carried out.

The actuating lever 21 is in particular Fig. 5 shown.

The actuation arm 22 is designed for manual actuation by a user, not shown.

The actuating arm 22 can be curved or curved and/or ergonomically shaped. This is conducive to easy and comfortable operation.

The lifting arm 23 is designed to drive the pump device 4, in particular to actuate or compress the bellows 5 and/or to axially move the base 9, in particular upwards or in the direction of the outlet 5B and/or dispensing head 14.

The lifting arm 23 is preferably arranged at an end section of the actuating arm 22, in particular so that the greatest possible leverage can be generated during actuation via the actuating arm 22.

In Fig. 2 the actuating lever 21 is in a first or unactuated pivot position and in Fig. 3 shown in a second or actuated pivot position. Preferably, the actuating lever 21 can be pivoted between the first or unactuated and the second or actuated pivot position.

The movement from the first to the second pivoting position is preferably carried out by manual actuation or pivoting of the actuating lever 21 by a user, not shown.

The base element 10 of the base 9 forms or has a counter surface or actuating surface for the actuating lever 21 or lifting arm 23. The actuating lever 21 or lifting arm 23 preferably rests on the base element 10 or the actuating surface formed thereby and/or acts on it and/or exerts a force thereon, in particular when pivoting from the first to the second pivoting position.

By actuating the actuating lever 21 or the actuating arm 22, in particular by pivoting from the first to the second pivoting position, the bellows 5 is preferably actuated or compressed and / or deformed or moved from the rest position to the compressed position. This is done in particular by the fact that during the actuation or pivoting movement of the lifting arm 23 rotates about a pivot axis or a bearing part 24, so that an end of the lifting arm 23 assigned or facing the base 9 is raised or moved in the direction of the bellows 5.

In particular, an actuation of the actuation lever 21 or a pivoting of the actuation lever 21 from the first to the second pivot position causes compression of the bellows 5 and/or discharge of the fluid F.

Preferably, a movement of the actuating lever 21 from the second or actuated pivot position (back) into the first or unactuated pivot position occurs automatically or no active movement or actuation of the actuating lever 21 is required for this. A movement from the second to the first pivot position can preferably be carried out by a user releasing the actuating arm 22.

The expansion of the bellows 5 and/or the movement of the actuating lever 21 from the second to the first pivot position, in particular caused by the expansion, is preferably carried out by the (elastic) restoring force, which is caused by the previous elastic deformation or compression of the bellows 5 becomes. When the bellows 5 expands, the base 9 or the base element 10 or the actuating surface formed thereby preferably acts on the actuating lever 21 or lifting arm 23 or exerts a force on the actuating lever 21 or lifting arm 23, so that the actuating lever 21 is moved or pivoted from the second pivot position into the first pivot position.

The lifting arm 23 is formed by two mutually parallel, in particular arm-like or web-like elements 23A, which are connected to or arranged on the actuating arm 22 on one side and on the end side opposite the actuating arm 22 by a further element 23B, which is transverse or . Arranged at right angles to the elements 23A, are rigidly connected to one another. In this way, a lifting arm 23 that is both stable and saves material is formed. However, other solutions are also possible here.

A particularly rounded or cylindrical bearing part 24 is arranged or fastened between the elements 23A. The bearing part 24 preferably runs transversely, in particular vertically, between the elements 23A. The bearing part 24 is preferably formed in one piece with the lifting arm 23 and/or the actuating arm 22. For example, the actuating lever 21, the actuating arm 22 and/or the lifting arm 23 can be formed by a (one-piece) injection molded component. However, other solutions are also possible.

The actuating lever 21 is pivotally mounted on the dispensing device 2, in particular the housing 2A or the connecting part 20, by means of the bearing part 24.

The bearing part 24 preferably forms a rotation axis or pivot axis about which the actuating lever 21 can be pivoted or is pivoted when actuated.

The connecting part 20 has a bearing 25 for the bearing part 24 which is complementary to the bearing part 24. The bearing 25 is designed in particular for the preferably rotatable holding or mounting of the bearing part 24 or actuating lever 21. In particular, the bearing part 24 can be arranged or fastened, preferably in a latching manner, in the bearing 25, in particular with the bearing 25 holding the bearing part 24 in a form-fitting manner and/or at least partially surrounding it.

In Fig. 1 to 3 the actuating lever 21 is shown in a position of use. The position of use is preferably that position or relative arrangement of the actuating arm 22 and lifting arm 23 to one another in which an actuation of the actuating lever 22 for dispensing the fluid F takes place or can take place. In particular, the term “position of use” refers to a relative arrangement of the actuating arm 22 and the lifting arm 23 to one another, but not a pivoting position of the actuating lever 21.

The lifting arm 23 and the actuating arm 22 are preferably arranged transversely, in particular at least substantially perpendicularly, to one another - at least in the position of use.

Preferably, the actuating arm 22 can be folded down, in particular from the lifting arm 23, and/or the actuating arm 22 is movable relative to the lifting arm 23, in particular foldable or pivotable. This functionality is particularly important in the Fig. 6 to 8 illustrated embodiments realized.
