Definitions

  • This invention relates to an atomiser apparatus, for example, an aerosol container, where the dispensing of the fluid is by an electromechanical actuator.
  • the propellant takes the forni of a liquid when it is highly compressed, even if the temperature is well above its boiling point.
  • the product is poured into the container before the can is sealed.
  • the propellant however must be forced into the container at very high pressure such that it does not have enough room to expand into a gas.
  • This propellant will remain in liquid form so long as the pressure is maintained; when the valve is open, the pressure of the liquid propellant is instantly reduced and the liquid propellant begins to boil.
  • a gas layer is fonned at the top of the container. This pressurised gas layer pushes the product, as well as some of the liquid propellant, up the dip tube to the nozzle. As the propellant/product mixture leaves the nozzle, the propellant rapidly expands into gas and the product is ready for application.
  • the aerosol container is configured as follows: the container is first partially filled with product, the container is sealed, and then the gaseous propellant is pumped through the valve system at high-pressure. Inside the sealed container, this highly pressurised gas exerts a downward force on the product such that when the valve is opened, the propellant forces the product out of the container via a dip tube. A narrow nozzle serves to atomise the product, breaking it up into tiny droplets, which forni a spray plume.
  • the consistency of the sprayed product depends on several factors, most notably, the chemical constitution of the propellant and product, the ratio of propellant to product, the pressure of the propellant and the size and shape of the valve system.
  • the actual amount of propellant found in an aerosol container varies depending on the product: a higher percentage for fine sprays, a low percentage for foam or mousse.
  • the use of propellants in aerosol containers has long been associated with damage to the environment and the 'greenhouse effect' , which is the rise in temperature that the Earth experiences caused by certain gases in the atmosphere trapping energy from the sun.
  • gases include carbon dioxide, nitrous oxide, methane, halogenated fluorocarbons (HCFCs) and hydrofluorocarbons (HFCs), some of which have been used as propellants in the past.
  • HCFCs halogenated fluorocarbons
  • HFCs hydrofluorocarbons
  • Patent Citation 0001 EP 0615470 B (THE TECHNOLOGY PARTNERSHIP PLC). 1992-12-04. which describes a fluid droplet production apparatus, for example, for use as an atomizer spraying device, having a membrane which is vibrated by an actuator, which has a composite thin- walled structure and is arranged to operate in a bending mode. Fluid is supplied directly to a surface of the membrane and as the membrane vibrates, fluid is sprayed therefrom.
  • the standard valve system of a traditional aerosol container affects the distribution of the product droplets within the spray plume.
  • the regularity of the droplet distribution will reach an optimun at a particular distance from the nozzle. Away from this optimun distance, the spray plune will become increasingly non-unifoim and consequently some areas of the application surface will receive more product than other areas. In practice, achieving this optimum distance is difficult, especially for the blind or partially blind. Equally, ensuring that the centre of the spray plune is aligned with the target surface requires excellent hand-to-eye coordination and for many it is not very easy to do. If not done, some areas of the target surface may even be missed altogether.
  • the invention provides a device for production of a fluid droplet spray comprising an electromechanical actuator, the device having an energy source, a membrane, and an actuator adapted to vibrate the membrane, characterised in that the device further includes a means to target an application surface powered by the energy source.
  • the device By using an electromechanical actuator to dispense product from the container, the device is not contributing to the 'greenhouse gas' effect and it is not damaging the environment.
  • the targeting means assists the user in aiming the spray plume during normal usage. This combination benefits the environmentally aware user by reducing the amount of product wasted during inaccurate spraying of the product. Additionally, it also helps the user to avoid wasting money, since the product is only used where it is required.
  • the targeting means comprises a plurality of light emitting diodes.
  • the light beams emitted by the light emitting diodes are configured to coincide at an optimun distance from the device and this moment of coincidence provides feedback to the device.
  • the device is especially useful for applying product, e.g. cosmetics, to the face.
  • the moment of light beam coincidence can be used to trigger a visual indication conveying to the user a signal that the device is ready for use. This is an excellent way of reassuring the user that the spray distribution is now at its optimun and that an even distribution of the product will result if the device is operated at this distance.
  • An audible signal would make the apparatus particularly useful for partially sighted or blind people. Automatic dispensing of the product could further enhance the user experience.
  • the configuration of the light emitting diodes is detennined by the angle of the diodes from the nonnal and the spacing between the diodes.
  • the angle of the diodes is between 5-20 degrees from the nornial and the spacing between the diodes is between 2-6cm.
  • the angle of a light emitting diode is measured from the spray plane (Z-plane).
  • the angle will be set between 5-20 degrees and the light emitting diodes will be spaced between 2-6 cm apart as these figures provide the optimun set-up conditions required for the even spray application of cosmetic and personal care products when the distance to the application surface from the nozzle is set at 0.3m.
  • the targeting means comprises a plurality of light emitting diodes arranged such that the light emitted by the light emitting diodes defines a generally circular area and one of the diodes is focus able on the application surface and upon accurate focus of the diode a feedback signal is sent to the device.
  • This embodiment provides the user with the capacity to accurately align and focus the spray on an application surface.
  • the light beams from the light emitting diodes define a generally round spray area where the product will be sprayed.
  • the application surface is totally within the lit area provided by the light emitting diodes, the product is ready to be sprayed.
  • One of the light emitting diodes is also focusable on the application surface. When the application surface is at desired distance from the spray dispenser, the light beam that falls on the application surface is sharp and clear.
  • a device for production of a fluid droplet spray comprises an electromechanical actuator having an energy source, a membrane, and an actuator adapted to vibrate the membrane, characterised in that the energy source powers a sensor that is adapted to detect infra-red of wavelength between 5 and 20 ⁇ m and upon such detection a feedback signal is sent to the device.
  • the advantage of this embodiment is that the device acts as a proximity sensor for application surfaces in difficult locations, analogous to car parking sensors.
  • the device makes use of the fact that himan skin emits infrared at a wavelength of lO ⁇ m; the device incorporates a passive short-range sensor that detects the presence of infrared and upon detection the sensor sends a feedback signal to the device.
  • This feedback infom is the user that the device has detected the body's infrared and does so by providing an audible and/or visual signal. The feedback can even be used to trigger the device to automatically dispense the product from within.
  • the advantage of this is that the user is able to tell when he/she has held the device at a distance near enough to the body to apply the product, even when he/she cannot easily see the application surface.
  • the automatic dispensing of the product is especially beneficial to the blind, partially blind and/or deaf or hard of hearing.
  • Figure 1 is a schematic of a prior art product dispenser, such as an aerosol can.
  • Figure 2 is a schematic of an embodiment of the invention.
  • Figure 3 is a schematic of another embodiment of the invention, as applied to the face of a mannequin.
  • Figure 4 is a schematic of a further embodiment of the invention.
  • a typical product dispenser (1) when in use, will emit fluid in a plume (2) that contains both unifonn (20) and non-uniform (21) spray distribution areas.
  • fluid particles are evenly distributed in the X (90), Y (91) and Z (92) planes.
  • the Z (92) plane is referenced as being the general direction that the fluid spray will travel.
  • non-uniform spray distribution areas (21) the fluid particles are decreasingly regular in their distribution and appear more and more randomly spaced apart as they travel away from the aerosol nozzle (11) in the Z-plane (92).
  • the fluid will be unevenly distributed on the application surface (3) and the product application will appear patchy and unattractive. Fbwever, if the application surface (3) is placed within the uniform spray distribution area (20), the finish of the product application will appear smooth and flawless.
  • Figure 2 shows an embodiment of the invention, which helps to determine the optimun distance that the application surface (3) should be placed at relative to the nozzle (11) to ensure that it is within the unifonn spray distribution area (20).
  • a plurality of light emitting diodes (4) is spaced a distance apart (40) and each is placed at an angle (41) relative to the Z-plane (92).
  • the light beams (42) from the light emitting diodes (4) coincide. If this distance (44) is set to be the optimun distance for best product spray distribution, within the unifonn spray distribution area (20), then the device can be used as an aid to achieving a smooth and flawless product application upon an application surface (3) such as a face.
  • FIG. 3 a further embodiment of the invention is shown.
  • light shining from the light emitting diodes (4) illuninates a generally circular area (43).
  • the geometry of this illuminated area (43) is configured to correspond to the geometry of the spray plune (2) (see Fig 1). This means that when the spray plume (2) is directed towards a face (6), the user can align the illuninate area (43) with the outline of his/her face and be confident that the spray plume (2) will reach the face (6).
  • Figure 4 shows a schematic of infrared rays (5) being emitted by the surface of the body (31). These rays are detectable up to a distance (50) from the application surface, after which the energy of the waves generally dissipates into the surrounding environment.
  • the device contains an infrared sensor. If the device is placed at a distance (50) from the application surface, then it will detect the presence of infrared. With feedback, this detection can be used to transmit a signal to the user that the device is at an appropriate distance from the body for product to be dispensed. This feedback can be audible or visual and can even be used to automatically activate the dispensing of the product from the device.
