Definitions
- the invention relates to a dispenser for a liquid according to the preamble of claim 1.
- WO 03/084362 Al a dispenser for liquid media is known. Such dispensers, as shown for example in FIG. 5, tend to leak unintentionally in the case of low-viscosity media such as, for example, penetrating oil or nail polish remover.
- the invention has for its object to develop a dispenser that is inexpensive to produce and reliably prevents leakage of larger quantities of the medium even with low viscosity media or liquids.
- the liquid dispenser according to the invention provides a metering unit which has a channel which has an inlet and an outlet, wherein the channel can be reduced in its cross-sectional area (DK) to at least one gap on at least one longitudinal section through a metering element arranged in the channel ,
- DK cross-sectional area
- Dispenser is an adapted to the properties of the liquid gap inexpensive to produce, since this is produced by two compared to the gap large-sized components. Such components can be produced with much less effort than a channel with an extremely small diameter.
- the core of the invention is thus a dispenser for low-viscosity liquids, which comprises a cost-effectively manufacturable micro-gap as a central component.
- the invention is provided to seal the inlet of the channel with respect to a storage space through a membrane and to make the membrane permeable to the liquid from the storage space to the inlet of the channel.
- the core idea of the membrane is thus a dispenser for low-viscosity liquids, which is sealed off by a membrane acting as a pressure-controlled valve against the liquid present in the storage space, as long as the liquid is not exerted by human or mechanical force on the wall of the tank increased pressure on the membrane becomes.
- the membrane has a self-closing opening, which is formed by at least one slot.
- a membrane is inexpensive to produce.
- such a membrane can also be produced from materials which are resistant to aggressive liquids. Through the thickness of the membrane and / or the slot length and / or the number of slots and / or intersecting Slits this is easily adaptable to liquids of different properties and in particular different viscosity.
- the membrane is also provided to hold the membrane by a conical section of the metering element or a shoulder formed on the metering element against the base body in front of the inlet of the channel. This makes it possible to dispense with a separate fastening component for the membrane.
- the invention provides mobility of the membrane on the metering element and in the longitudinal direction of the metering element. Movement in the direction of the channel is producible by increasing a pressure of the liquid. As a result, it is also possible to use rigid materials for the membrane, since this does not have to deform in order to open and close a gap in the region of the gap.
- the membrane with a resilient and peripheral edge web.
- edge web can both achieve an effective seal against the body as well as realize sufficient spring properties.
- the membrane of an elastically resilient sealing ring or O-ring and an annular disc.
- This allows a cost-effective production, since sealing rings in a variety of sizes are available as standard components and for the annular disc, a cost-effective material can be used, since this does not have to have any resilient or elastic properties.
- the invention provides, the shell of the tank in at least a portion of flexible and thus depressible form, in order to increase a pressure in the storage space of the tank by a finger pressure.
- Such a tank can be produced in a particularly cost-effective manner with respect to a tank with a mechanical or propellant-driven pump device or conveying device.
- a chamber between the membrane and the inlet of the channel is provided to form a chamber between the membrane and the inlet of the channel.
- Such a pre-chamber allows bulging of individual lobes of the membrane in the direction of the channel and thus prevents unwanted sealing of the inlet of the channel through the membrane when the liquid is pressed out of the storage space.
- the invention also provides for closeability of the outlet of the membrane. As a result, unwanted drying out or undesired odor nuisance by the dispenser can be effectively counteracted.
- the invention provides to arrange an applicator at the outlet of the channel. This allows the dispenser to be optimized for a wide variety of applications.
- the invention provides in particular to form the applicator as a nozzle. As a result, a precise application of the liquid is possible even in hard to reach places.
- the invention also provides for the applicator to be designed as a brush element.
- a brush element By a brush element a targeted and even distribution of the liquid over a larger area is possible.
- the invention provides to close the applicator by a lid. This can cause a dry or An odor nuisance can be prevented by the applicator.
- a cross-sectional area (DD) of the metering element and the cross-sectional area (DK) of the channel are formed at a common interface as congruent surfaces, wherein the cross-sectional area of the metering element is reduced by a recess and / or the cross-sectional area to form the gap for the liquid of the channel is increased by a recess in a base body in which the channel is formed.
- an optimal manufacturing process can be selected for each material used.
- At pin-shaped or cylindrical or disc-shaped metering elements made of plastic can be produced, for example, with simple means by reworking a flattening.
- the invention provides that the dosing over its entire length has a constant cross-section and / or that the channel over its entire length has a constant cross-section. As a result, both components manufacturing technology are easy to produce.
- One embodiment of the invention provides to close the inlet of the channel through a first end of a tube or a tube, wherein the tube or the tube opens with a second end in the storage space of the tank.
- the invention provides a brush element comprising a plurality of bristles and a staple, the bristles being U-shaped through the annular staple and point with their free ends in the same direction.
- a brush element can be easily mounted, since no free ends of the bristles point in the mounting direction and so damage to bristles during assembly is excluded.
- the invention also provides for the metering needle or metering disk to be completely fixed within the channel between an inlet and an outlet of the channel, with the metering needle terminating, in particular, offset from the outlet of the channel.
