Definitions

  • the present invention relates to a dispensing device for dispensing a fluid and a dispenser for dispensing a fluid.
  • 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.
  • 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.
  • 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 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.
  • a dispensing device 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.
  • 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.
  • 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.
  • 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.
  • an additional ventilation valve or the like can be dispensed with.
  • 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.
  • 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.
  • 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.
  • 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.
