Definitions

  • the invention generally relates to devices or apparatuses to dispense fragrances, and more specifically to a fragrance or scent diffuser.
  • fragrances include: reed diffusers, candles, plug-in diffusers, gel diffusers, room sprays, potpourri, and ultrasonic mist devices.
  • a fragrance diffuser has a diffuser element connecting a first reservoir to a second reservoir. As a fragrant oil flows between the reservoirs, the diffuser element becomes saturated with oil and diffuses the fragrance or scent.
  • the diffuser is self-contained, easy to interact with, without creating a mess.
  • the diffuser is relaxing and pleasant to watch as it flows through from one end and drips to the other, releasing one small bubble at a time. It is refillable, transportable, and the intensity of the scent release can be controlled easily by saturating the wood more or less often.
  • two glass containers are connected by a wood piece that absorbs scented liquid which passes through it, soaks it up, and as it evaporates it diffuses scent into its environment.
  • the wood piece has a hole which goes all the way through it and two to three others that allow the liquid to fully penetrate and saturate the wood.
  • the wood piece has two layers: the inner which is solid and fully saturates, and outer that is cut into slats or ridges. The outer layer remains dry or relatively dry to the touch and the spaces in between allow for the evaporation, leading to scent diffusion of the inner layer.
  • the wooden piece has two narrower ends which are cut at a precise angle that allows the liquid to drip through between the two glass containers.
  • the wood piece also has two plastic O-rings that function as a barrier to prevent the scented liquid from seeping through outside of the small holes in the wood.
  • the wood pieces are bonded to prevent excess leaking of the liquid.
  • the glass containers are identical in shape and size and can be made of other nonpermeable materials.
  • an apparatus includes: a first reservoir having a first opening to a first chamber of the first reservoir; a second reservoir having a second opening a second chamber of the first reservoir; a diffuser element, where the diffuser element includes cellulose (e.g., wood), the diffuser element is connected between the first opening of the first reservoir and the second opening of the second reservoir, and an outer surface of the diffuser element includes slats and grooves, and the slats extend parallel to each other; and a first channel, extending through the diffuser element, the first channel connecting the first chamber to the second chamber.

  • An implementation of the fragrance diffuser is referred to as“scent glass.”
  • the diffuser includes a first reservoir 308 and a second reservoir 310.
  • the first reservoir has an opening 311, and the second reservoir has an opening 313.
  • the reservoirs can be glass containers, flasks, or jars, but can be vessels of any material that can hold a liquid, including polymers, plastics, polycarbonate, and the like.
  • the reservoirs are transparent or translucent (e.g., frosted or etched material) so the contents of the reservoir are visible from an exterior of the reservoir. The user will be able to check a level of the oil in the diffuser.
  • the reservoir can be opaque. Both reservoirs can have the same shape, or can be different shapes.
  • the glass can be blown glass, crystal, or leaded crystal.
  • the diffuser element is connected between opening 311 of the first reservoir and opening 313 of the second reservoir.
  • the diffuser element has an internal channel 322 (shown in broken lines) extending through it.
  • the channel connects an interior chamber 325 of the first reservoir to an interior chamber 328 of the second reservoir.
  • the diffuser element is made from a wood, plant-based, or cellulose fiber materials. However, in other implementation, other materials may be used that provide an equivalent diffusing capability or functionality.
  • An outer surface of the diffuser element includes a number of grooves 333 and 337.
  • the grooves extend parallel to each other.
  • the diffuser element can have any number of grooves, more or fewer than shown in the figure, such as 2, 3, 4, 5, 10, 20, or more grooves.
  • the grooves extend around the diffuser element.
  • a slat or ridge 338 is formed by the grooves, such as one slat between two grooves.
  • the slat or ridge may also be referred to as a fin or protrusion.
  • the grooves may be considered spaces adjacent to the slats or ridges.
  • the groove forms a cylindrical shape, and the slats or ridges form what appear as parallel disks.
  • the shape of the disks can be a circle, but other shapes in other implementations such as ellipse, oval, obround, polygonal, square, rectangular, or other.
  • the grooves and slats or ridges are symmetric about an axis through a middle or center of the diffuser element in a first direction 339, while slats or ridges extend transverse or perpendicular to the axis in a second direction 340.
  • the slats or ridges are oriented perpendicular to the direction of the flow of oil through the channel.
  • the slats or ridges can be oriented parallel to first direction 339 or other angles relative to the axis or oil flow direction.
  • an overall length of the diffuser element in first direction 339 is greater than an overall width in second direction 340. However, in other implementations, the length of the diffuser element in first direction 339 is less than the width in second direction 340.
  • Gasket 341 seals the opening 311 of the first reservoir, which prevents a fragrant oil 350 from leaking out of the reservoir.
  • Gasket 343 seals the opening 313 of the second reservoir.
  • the gasket can be rubber, neoprene, or other material that is compatible with and can seal oil or other liquids. Although only a single gasket is described per side, there can be multiple gaskets, such as 2, 3, 4, or more gaskets per side, as needed to improve the seal. Typically, there are the same number of gaskets per side, but the number can be different (in any combination such as 1 and 2, and 2 and 3).
  • a package or kit includes a scent glass or fragrance diffuser with an aromatic fragrance oil or liquid prefilled in one of the reservoirs (e.g., a first reservoir).
  • a user places diffuser on a table or other surface in a space or place where the user wants to dispense the fragrance.
  • Each reservoir has a relatively flat base surface which can rest stably on a flat surface.
  • the diffuser is placed on the surface such that a reservoir (e.g., first reservoir) with oil (e.g., oil 350) is above the diffuser element and the other reservoir (e.g., second reservoir).
  • oil e.g., oil 350
  • the other reservoir e.g., second reservoir.
  • the oil will flow, via gravity, into contact with the diffuser element, which absorbs some of the oil.
  • some of the oil will pass through the channel in the diffuser element and drip 363 into the lower reservoir (e.g., a second reservoir).
  • the oil drips into the lower reservoir there may be some bubbles 366 that flow upward through the oil of the upper reservoir.
  • all the oil in the upper reservoir will be collected (e.g., an oil 370) in the lower reservoir, and the oil drops will stop.
  • the time for an upper reservoir, full of oil, to empty by dripping into the lower reservoir is about 20 minutes.
  • the exact time can vary, such as 6, 8, 10, 15, 25, 30, 40, 50, 60 (i.e., 1 hour), 90, or 120 minutes, and depend on factors such as channel size, temperature, and viscosity and amount of oil.
  • the user can start the process over again by turning the diffuser over, such that the upper reservoir (e.g., second reservoir) becomes the lower reservoir (e.g., first reservoir), and the lower reservoir becomes the upper reservoir.
  • the fragrance oil will be consumed.
  • the user can refill or top off the fragrance oil with the same or different oil (e.g., different scent) by removing the diffuser element (which also acts as a stopper) from one of the reservoirs, and then refill that reservoir.
  • the diffuser element is inserted back in the reservoir to complete the refill process.
  • the package or kit with the fragrance diffuser is not prefilled with oil, and the user will fill the oil, such as described above.
  • the fragrant oil can be any liquid or oil with a volatile fragrance or aromatic constituent, such as an essential oil.
  • the fragrant oil can be a mixture of a carrier oil and an essential oil.
  • a carrier oil is an oil with a neutral smell and is generally less volatile than an essential oil.
  • An essential oil is an oil that comes from a plant that has an aroma.
  • the aromatic constituent may be a synthetic aromatic constituent (e.g., synthetic oil, aldehyde, ketone, or alcohol).
  • the fragrant oil mixture can also include an alcohol (e.g., isopropyl alcohol or ethanol) and water. The alcohol can help emulsify the solution and also volatilize the aromatic constituent of the solution.
  • the fragrant oil solution used may be, for example, one of many reed diffuser refill oils that are available to consumers.
  • Some examples of carrier oils include sweet almond, apricot kernel, avocado, evening primrose, jojoba, and others, and combinations of these.
  • fragrance can be a combination of a plant-based or natural fragrance and a synthetic or artificial fragrance.
  • the diffuser element is made of wood, plant-based material, or other material with cellulose fibers.
  • the cell walls of plant material are largely made of cellulose.
  • the diffuser element absorbs the fragrant oil, and the surfaces of the diffuser element become wetted or saturated with the fragrant oil. These surfaces are exposed to the air of the exterior space. Through evaporation, the volatilized chemical compounds, which include molecules responsible for the fragrance, of the oil are carried into the air of the exterior space.
  • Some examples of woods that can be used for the diffuser element includes pine, oak, cherry, poplar, willow, rattan, cedar, fir, hemlock, redwood, spruce, beech, cypress, alder, aspen, birch, mahogany, rosewood, teak, wenge, maple, and others, and any combination of these.
  • one part may be made from one type of wood, while the other part is made from another type of wood.
  • the fragrance diffuser is a significant improvement over reed diffusers.
  • current reed diffusers consist of one open container and several wooden reeds that stick through the opening. The reeds absorb the liquid on the bottom first, then have to be taken out of the container to be turned over so the saturated end can be exposed to open air and allowed to diffuse into the environment.
  • Wood, plant-based, or cellulose fiber materials are used for the diffuser element due to their oil absorbing characteristic. These materials have interstices, intercellular spaces, or pores, or a combination, that trap the oil. Based on diffusion principles, the oil is conducted, via a capillary action, to surfaces where the oil can evaporate.
  • the materials absorb oil into intercellular spaces or pores based on diffusion principles, which can be characterized based on Fick’s laws of diffusion.
  • the oil is absorbed into the material until equilibrium is achieved. In equilibrium, the oil will be an isotonic solution in relation to the material.
  • the diffuser element exposed to the air there will be a hypotonic solution of the oil.
  • the oil and fragrance will evaporate or diffuse into the air, and this will continue until equilibrium is achieved.
  • the diffuser element continues to dispense fragrance as long as this diffusion cycle continues— slowly moving oil from within the diffuser (where the oil is at a higher concentration) into the air of the room or space (where the oil is at a lower concentration). Equilibrium can be achieved under circumstances such as when the oil is no longer in contact with the diffuser element or when the oil has been entirely consumed.
  • the inside surfaces oil should continue to be kept in contact with the oil. So, when the oil has completely drained into the lower reservoir, the user can flip over the diffuser to place the oil in contact with the diffuser element again (e.g., opposite diffuser element end). The flow of the oil in the diffuser is reversible, changing directions depending on which reservoir is the upper reservoir.
  • the system is completely sealed and enclosed.
  • the oil is sealed in the unit, and unlike a reed diffuser, the oil cannot be easily spilled. There will be no drips that can occur when flipping the unit— unlike that may occur when flipping of reeds.
  • the user’s hand will not get oily because the user will flip the unit by holding and grabbing the reservoir surfaces, which are not oily.
  • the amount of oil that is absorbed by the diffuser element material depends on the amount of surface area touching the oil. The greater the surface area, the greater the absorption and rate at which oil can be conducted to the surfaces touching the air.
  • a hole is formed (e.g., drilling using a drill bit) to allow oil to gradually or slowly drip from the upper reservoir to the lower reservoir. This increases the surface area that is in contact with the oil, and also reduces the distance between the surfaces in contact with the oil and surfaces in contact with the air.
  • the surface area in contact with the oil can be increased by drilling additional holes or openings into the diffuser element. Some of these holes may not necessarily go through the diffuser element entirely, from first reservoir to second reservoir. There may be other features used to increase the surface area, such as wings, slats, ridges, pins, spirals, grooves, recesses, trenches, protrusions, fins, or other patterns on the interior diffuser element surfaces.
  • Wood or plant-based materials usually have grains running through the material.
  • the diffuser element is made so that the grains extend in the same direction as the flow of the oil, which is a similar direction as water flow and diffusion (e.g., via osmosis through the plant cells) in the tree trunk or plant stem. By orienting the wood grain in the same direction as the water flow, this can generally increase a rate of diffusion and absorption of oil in the material.
  • the diffuser element is made so that the grains extend in perpendicular to or in a different direction as the flow of the oil.
  • Figure 4 shows a method of making a diffuser element from a block of material.
  • the diffuser element made from a block of wood, plant-based material, or other material with cellulose fibers.
  • the block of wood can be a solid wood, plywood, pressed wood, fiberboard, particle board, medium-density fiberboard, hardboard, laminated wood, treated wood, wood fiber with a veneer, or others.
  • the diffuser element can be manufactured using woodworking or machining techniques (e.g., wood turning or others) and equipment. Some examples of working equipment include lathe, saw, routers, cutters, and chisels, files, sander, sandpaper, grinder, belt sander, router, and others.

Abstract

Un diffuseur de parfum comporte un élément diffuseur reliant un premier réservoir à un second réservoir. À mesure qu'une huile parfumée s'écoule entre les réservoirs, l'élément diffuseur devient saturé d'huile et diffuse le parfum ou l'odeur. Le diffuseur est autonome, facile à interagir avec, sans créer de mess. Le diffuseur est relaxant et agréable à regarder à mesure qu'il s'écoule à travers une extrémité et s'égoutte vers l'autre extrémité, libérant une petite bulle à la fois. Il est rechargeable, transportable, et l'intensité de la libération d'odeur peut être contrôlée facilement en saturant le bois plus ou moins souvent.
