Definitions

  • the invention relates to a liquid dispenser for dispensing liquids, in particular a liquid dispenser for dispensing cosmetic liquids.
  • Liquid dispensers of the generic type have a reservoir for storing the liquid before the discharge and an applicator to which the liquid can be conveyed from the reservoir for the purpose of discharge.
  • a pressure generating device is part of a generic liquid dispenser.
  • a typical pressure generating device is a liquid pump, usually in the form of a piston pump or bellows pump, through which a portion of the liquid is drawn into a pumping chamber as part of a return stroke movement and is pumped from there to the applicator as part of a stroke movement.
  • a fundamentally different form of a pressure generating device can exist in the case of generic dispensers in the form of a pressure accumulator which pressurizes the reservoir as a whole.
  • Such liquid dispensers are particularly common for deodorant.
  • the energy stored in the dispenser in the form of compressed air or in the form of a propellant gas causes the reservoir to be pressurized, so that discharge can be triggered by an actuating handle that controls a switching valve.
  • liquid dispensers with pressure generating devices in which the compressed air is not introduced here during the course of the manufacture and filling of the liquid dispenser, but is only introduced by the end user by shaking or manual pumping.
  • the actuating handle is provided for controlling a switching valve which, after the required discharge pressure has been built up, discharges the liquid which has been pressurized in this way from the reservoir via the applicator.
  • Dockument EP1249187 discloses a liquid dispenser for dispensing liquids with a pressure generating device.
  • the object of the invention is to develop a liquid dispenser such that it has an advantageous embodiment of a pressure generating device.
  • a liquid dispenser according to claim 1 for dispensing liquids, in particular cosmetic liquids for application to the skin which has a reservoir for storing liquid before discharge and an applicator through which the liquid is dispensed into an environment can be.
  • the reservoir and the applicator are connected via an outlet channel.
  • the outlet channel is designed as a valveless outlet channel which creates a permanent connection between the reservoir and the likewise valveless applicator, so that there is no liquid-tight seal between the reservoir and the applicator itself.
  • the preferred configuration provides that the liquid dispenser has a liquid channel with a pressure-dependent opening liquid outlet valve, which opens at a minimum opening pressure sufficient to open the liquid outlet valve.
  • the liquid dispenser has a pressure generating device, by means of which liquid can be pressurized in the reservoir in order to be able to convey it to the applicator through the outlet channel, which is provided with a valve or with a pressure-dependent opening valve.
  • the pressure generating device has an air pump device and an actuating pressure chamber fed thereby.
  • the actuation pressure chamber adjoins the reservoir and is separated from the reservoir by a displaceable wall, so that an excess pressure in the actuation pressure chamber leads to an excess pressure in the reservoir.
  • the pressurized surface of the wall in the reservoir and in the actuation pressure chamber is identical, so that identical pressures are also established.
  • the wall can also have pressure surfaces of different sizes on both sides, so that it acts as a pressure transducer.
  • the air pump device of the pressure generating device has an actuation handle for manually actuating a pump, air being introduced into the actuation pressure chamber by means of the actuation handle can be pumped in, so that the overpressure in the actuating pressure chamber and in the reservoir rises sufficiently to convey liquid from the reservoir to the applicator.
  • the discharge is effected directly via the actuating handle and its effect on the pressure in the actuating pressure chamber.
  • a further actuation by the user in the manner of opening an outlet valve is not provided.
  • the actuating handle acts on the air pump device, which is particularly intended to press air into the actuating pressure chamber by repeated depression and release.
  • the air pump device preferably has a pump chamber which is temporarily connected to an environment by a pressure-dependent opening air inlet valve and which is temporarily connected to the actuating pressure chamber by a pressure-dependent opening air outlet valve.
  • a pressure-dependent opening air inlet valve When the operating handle is pressed down or operated as intended, the air inlet valve is closed in the direction of the surroundings and the air outlet valve is opened in the direction of the operating pressure chamber. When released, the air outlet valve closes, the air inlet valve opens and air flows into the pump comb from the surroundings.
  • the pump chamber of the air pump device is preferably formed by a bellows, in particular by a bellows open on both sides.
  • a bellows represents a simple and advantageous method of realizing the pumping chamber.
  • due to the elastically deformable material it is suitable for providing an integrally molded valve surface for the air inlet valve or the air outlet valve.
  • one end of the bellows associated with the actuating handle is movable relative to the actuating handle and has an inlet opening which is closed when the actuating handle bears against the bellows, in particular by means of a conical one Closing section on the operating handle.
  • This design allows the inlet valve to be realized only with components that are already present in a bellows design.
  • the air pump device has a separate return spring, in particular preferably in the form of a helical spring, by means of which the actuating handle is pressed in the direction of an initial position. This results in a quick return path of the actuating handle, which is particularly advantageous if the liquid dispenser is designed in such a way that several actuations of the actuating button are required to build up the pressure in the reservoir required for the discharge.
  • the return spring also serves to enable the actuating handle to be reset more quickly with respect to the bellows and thus to open the air inlet valve.
  • the pressure increase required for this liquid delivery depends on the design of the outlet channel and to a lesser extent also on the orientation of the dispenser. Basically, it is considered to be advantageous if only a few air pump strokes via the actuating handle are required to discharge liquid, ideally only one or two air pump strokes.
  • the actuation pressure chamber is sufficiently completely sealed off from the surroundings and the air inlet valve closes sufficiently tightly in order to maintain a pressure which has been introduced once in the actuation pressure chamber for a longer period of at least a few days.
  • the valve is preferably designed such that the valve remains closed during transport in an upside-down position with the outlet valve pointing downwards and / or when the liquid dispenser is handled normally.
  • a liquid throttle can be provided for this purpose in the outlet channel, preferably with a minimum clear cross section of maximum 1 mm 2 . It is advantageous if the liquid throttle has a throttle section of at least 2 mm in length, within which the clear cross section is at most 1 mm 2 .
  • a plurality of discharge channels can also be provided, which lead to a common applicator, each of the discharge channels then preferably having a throttle section, the minimum clear cross section of which is at most 1 mm 2 and / or which has a throttle section of at least 2 mm in length.
  • the optimal dimensioning of the throttle section or the throttling effect of the outlet channel depends on the reservoir and its filling.
  • the liquid dispenser is preferably designed in such a way and its valveless outlet channel is dimensioned such that when the dispenser is upside down with a full reservoir, the flow resistance through the outlet channel is so great that the hydrostatic pressure of the liquid in the reservoir alone is not sufficient to overcome it.
  • the liquid dispenser preferably has a cap that can be removed and re-placed on a base of the liquid dispenser. This cap isolates liquid-carrying parts of the applicator from its surroundings.
  • the insulation is liquid-tight and preferably also gas-tight.
  • a gas-tight design has the effect that even an unusually low ambient pressure, for example in the context of transport by plane, does not suck liquid out of the reservoir into the applicator due to the low overpressure required for the discharge.
  • the reservoir and the actuation pressure chamber are provided within an at least partially cylindrical housing part.
  • the displaceable wall is designed in the form of an inherently rigid separating piston, which is provided in the housing part in a sealing manner so that it can slide against a cylinder wall of the housing part.
  • the separating piston slides on the inside of the cylinder wall, whereby it moves in the manner of a trailing piston in the course of the progressive emptying of the reservoir. Unlike the trailing piston, however, this is not the consequence of emptying the reservoir, but rather the cause of the emptying. Assuming friction-free sliding and the separating piston as well as a uniform cross-section of the reservoir and the actuation pressure chamber, the same pressure is established in the liquid as in the actuation pressure chamber.
  • the separating piston is to effect a pressure conversion at the same time, it should be provided that its pressurizing surfaces provided on both sides have a different size.
  • the housing part requires cylinder sections of two different cross-sectional areas.
  • displaceable wall is in the form of a deformable and preferably pliable film wall.
  • This can be, in particular, a bag wall of a bag that forms the reservoir or the actuation pressure chamber.
  • Such a film wall in particular in the form of a thin plastic film or a composite film made of several material layers, represents a very simple way of exerting the pressure of the actuating pressure chamber on the liquid in the reservoir.
  • bags are to be used, as are similarly known from so-called airless dispensers.
  • the bag is located in an area surrounded by rigid walls, which separates the bag wall into two parts, namely the reservoir and the actuation pressure chamber.
  • the reservoir inside the bag and the actuating pressure chamber are preferably provided is arranged between the outside of the bag and the inner wall of an outer housing. In principle, however, the opposite arrangement is also possible.
  • a dispenser according to the invention can in principle be provided for very different application techniques.
  • the liquid can be discharged in the form of a liquid stream or in the form of drops.
  • the applicator has a discharge opening through which the liquid reaches an environment.
  • the liquid dispenser is designed in the manner of a crucible, in which liquid is conveyed from the reservoir into a removal area from the air pump device, from which the liquid, in particular in the form of a gel or a lotion, is removed with fingers can.
  • a dispenser according to the invention has a special discharge characteristic: the liquid can be discharged at a comparatively low pressure and over a longer period of time. This can be used to advantage in various fields of application.
  • a special design of the applicator provides that the applicator has an external application element provided for absorbing liquid, in particular in the manner of a porous application element or a brush. This has a receiving side for receiving the liquid supplied from the discharge channel and a dispensing side for dispensing the liquid onto a target surface.
  • An external application element for absorbing liquid is understood to be an application element which has a complex structure for temporarily storing liquid.
  • a complex structure can be formed by the bristles of a brush, such as a horsehair brush or a brush with porous bristles, which absorbs liquid such as make-up liquid, so that it can subsequently be dispensed onto the skin in a well-dosed manner.
  • a complex structure is also achieved in particular by a porous element in the manner of a three-dimensional and essentially dimensionally stable body, which is crisscrossed by a mesh structure with chambers, pores and passages, so that it has a storage effect for the liquid introduced, but so does can deliver dosed, especially controlled by the contact pressure on the skin.
  • the porous element can be designed in the manner of a deformable sponge or a deformable porous plastic block, so that liquid is increasingly released by being pressed against the skin.
  • designs are also expedient and encompassed by the invention, in which the Forces that usually occur during cosmetic application do not cause any noteworthy deformation of the application element, for example by the application element being formed from a rigid porous plastic or by using a porous ceramic or another porous material.
  • a rigid porous material can be, for example, a sponge made of a material which is offered under the trade name POREX.
  • the sponge or the application element can then have a Shore hardness A of at least 40, preferably of at least 60, particularly preferably of at least 80.
  • the external application element is arranged at the end of the outlet channel, so that the liquid supplied thereby is absorbed in the complex structure of the element and is distributed there in the pores and cavities.
  • the liquid passes through the pores or along the bristles to the delivery side, which is preferably designed in the manner of an application surface which can be passed over the skin, for example, with slight pressure in order to dispense liquid evenly here.
  • the pressure generating device with air pump and actuating pressure chamber provided according to the invention is of great advantage.
  • the conveyance of liquid into the application element due to air pressure takes place comparatively slowly, so that the liquid can be distributed evenly in the external application element.
  • the pressure generating device provided according to the invention with an air pump and actuating pressure chamber is therefore much better suited to supplying the application element than a delivery by means of a piston pump or the like, because if the pressure is too high, as would be feared there, the liquid can flow directly in the porous element without homogeneous spreading are pressed to the delivery side and emerge there unintentionally.
  • the liquid dispenser is preferably designed in the manner of a pin or elongated, wherein it has an outer housing which is oriented in a main direction of extension, preferably slim, and wherein the applicator and the actuating handle are arranged at opposite ends of the outer housing.
  • An uninterrupted discharge of the liquid can thus be achieved by passing the applicator side over the skin, while at the opposite end the actuating handle is actuated from time to time in order to feed new liquid into the application element.
  • the actuating handle is designed as an actuating pushbutton that can be depressed in the main direction of extension in the direction of the applicator. This permits advantageous handling with one hand, by means of which the applicator is pressed against the skin and can also be actuated in the same direction at the opposite end. This prevents the orientation of the liquid dispenser from being changed unintentionally by the actuation.
  • the liquid dispenser has a main housing component with an interior in which the reservoir and the actuation pressure chamber are arranged.
  • the air pump device comprises a partition on which a sealing surface of an air outlet valve is provided. This partition is provided as a one-piece part of the main housing component.
  • the design mentioned is simple in terms of production technology due to the small number of parts and allows elements of the air pump device to be supported securely on the partition, for example a pump bellows and / or a return spring.
  • the partition is also suitable for attaching a movable or deformable valve part of the air outlet valve.
  • a slotted valve component made of elastic material, which opens in a deformed state.
  • Such valves produced by an incision or slit in the elastic material are very well suited to enable reproducible opening behavior even at very low pressures.
  • Possible configurations include a flat valve, in which a slot perpendicular to this is made in a flat element, and a dome valve with a dome, in which the slot is provided.
  • the dispenser is particularly advantageous for cosmetic applications and is accordingly filled with such a liquid in the delivery state to the end customer.
  • a liquid in the delivery state to the end customer can be, in particular, make-up liquids, in particular with a solid component, or a cosmetic gel or a cosmetic lotion.
  • the liquid dispenser is suitable for all fields of application in which liquid is to be distributed evenly over surfaces by means of a kind of sponge.
