The present disclosure relates generally to storing and transporting scent cartridges.
The sense of smell (i.e., olfactory perception) is extremely important to humans. For example, the smell of smoke can alert a person of the potential dangers of a nearby fire. Additionally, smells can trigger memories and impact our emotions. Various forms of aromatherapy have been investigated in attempts to alter a person's mind, mood, cognitive function, and/or health.
A number of systems and devices have been developed for selectively providing olfactory sensations. For a variety of reasons, such systems and devices have proven to be inadequate and have not gained commercial acceptance. For example, the Smell-O-Vision system was developed over fifty years ago, which caused a number of different odors to be emitted from the seats in a movie theater when triggered by a film's soundtrack. That system was expensive and had technical problems. Accordingly, the Smell-O-Vision system was used in conjunction with only one film.
New approaches that enable users to quickly and easily generate customized scent specifications for communicating specific themes, ideas, and/or feelings using sequences and combinations of scents are desirable. Additionally, new systems and devices that dispense scents based on such scent specifications are desirable.

The headings and Abstract of the Disclosure provided herein are for convenience only and do not interpret the scope or meaning of the embodiments.
The scent dispensing device 100a may have various sizes and dimensions. For example, the size or dimensions of the scent dispensing device 100a may be in accordance with that of an article of clothing, accessory or another object to which the scent dispensing device 100a is coupled or physically secured. Furthermore, the scent dispensing device 100a may be deformable and may conform to the article of clothing or accessory to which the scent dispensing device 100a is physically coupled. The scent dispensing device 100a may be elastically deformable to conform to the article of clothing or accessory, so that the scent dispensing device 100a does not interfere with a shape, style or layout of the article or accessory. This allows the article or accessory to retain its aesthetic and functional forms. Accordingly, the scent dispensing device 100a may be used to complement the aesthetic and functional forms of the article or accessory by providing a pleasing scent without conflicting with the shape thereof.
As may be best viewed in
The scent dispensing device 100a also has a one or more selectively permeable membranes 110a, 110b (two illustrated). The selectively permeable membranes 110a, 110b may each be associated with a respective aperture 108a, 108b of the housing 102. The selectively permeable membranes 110a, 110b may be positioned in the flow path provided by the apertures 108a, 108b between the interior of the housing 102 and the external environment. The selectively permeable membranes 110a, 110b may selectively block moisture from the external environment from reaching the interior of the housing 102. The selectively permeable membranes 110a, 110b may, conversely, permit passage of gas between the interior of the housing 102 and the external environment including passage of at least one scent from the interior of the housing 102 to the external environment. Similar to the housing 102, the selectively permeable membranes 110a, 110b may also be elastically and/or resiliently bendable and resiliently conformable.
Air with or without scent may passively diffuse along a flow path and through a permeable membrane 100 (collectively referred to herein by the numeral alone). The air may be passively convectively conveyed or transferred within the interior 107 or from the interior 107 to the external environment 109 without being actively driven (for example, with the aid of a fan or an air jet).
As described herein, a scent cartridge of the one or more scent cartridges 106 may hold one or more scent media. The scent media may be in any form, such as liquid, solid or gas. In various embodiments, a scent cartridge 106 may be a wick that is twisted, braided or woven and made to absorb a liquid scent that is the scent media. The scent media may also be scented wax or powder.
A scent cartridge 106 may have any shape. For example, the scent cartridge 106 may be a disk having a radius that is greater than 5 or 10 millimeters (mm) and a height that is greater than 1 mm. Accordingly, an operator of the scent dispensing device 100 (for example, a human) may conveniently handle and manually manipulate the scent cartridge 106 when replacing a depleted scent cartridge 106 or swapping a scent cartridge 106 emanating one type of scent with another emanating a different type of scent. A person may carry multiple scent cartridges 106 (for example, in a scent cartridge holder) and may swap out the scent cartridge 106 of the scent dispensing device 100 with another scent cartridge 106 emanating a different scent depending on the scent the person wishes to wear.
The scent cartridge 106 may have a plurality of chambers 112, whereby a chamber of the plurality of chambers 112 is configured to hold a scent medium. A scent medium associated with one chamber may be different from a scent medium of another chamber. Scent provided by a scent medium, which may be any type of aroma compound, such as an essential oil, may combine with that emanating from another to compose aroma. A scent cartridge 106 holding a plurality of scent media may be used to produce various aromas. For example, aroma emanating from the scent dispensing device 100 may be chosen by selectively blocking passage from certain scent media and permitting passage from other scent media. The combination of scent emanating from the scent media may form a desired scent. For example, a scent cartridge 106 having five scent media may be used to produce
different aromas. If a scent cartridge has n scent cartridge chambers, the maximum number of potential scent combinations obtained from the scent cartridge (denoted as m) may be obtained as:
where the symbol ‘!’ denotes the factorial operator.
To increase the longevity of the scent media held by the one or more scent cartridges 106, it may be advantageous for the air circulating through the scent dispensing device 100a to be moisture-free. The selectively permeable membranes 110a, 110b may permit the passage of dry air therethrough but may be constructed to block the passage of moisture. For example, the selectively permeable membranes 110a, 110b may be made from hydrophobic or lipolithic woven or nonwoven material that inhibits the passage of moisture from the exterior environment to the interior and instead causes droplets of moisture to collect on an exterior surface of the selectively permeable membranes 110a, 110b. Due to the fact that materials having an affinity to fat (i.e., lipophilic materials) are typically water repellant, the selectively permeable membranes 110a, 110b may in many circumstances be composed of a material having lipophilic properties.
To increase the longevity or the “useful life” of the scent cartridges 106, it may be advantageous to employ multiple (e.g., two or more) layers of scent media in the scent cartridges 106. For example, the scent cartridges 106 may each include a first layer of scent media and a second layer of scent media, the second layer distinct and separate from the first layer of scent media. For instance, the first layer of scent media may take the form of a scent saturated fibrous material or fabric (e.g., felt or other nonwoven material, clumps, woven or knitted material). The fibrous material is saturated with fragrance (e.g., essential oil(s)), and optionally dried before being placed in a housing or retaining structure of the scent cartridge. For instance, the second layer may take the form of a scent impregnated or containing wax or similar material, for instance with a suspension of fragrance particles suspended therein. It may be advantageous to located the scent saturated fibrous material or fabric relatively closer to a portion of the scent cartridge that will be proximate an end users nose in use, relative to the scent impregnated or containing wax or similar material. The scent saturated fibrous material or fabric will tend to allow passage therethrough of scent originating from the from the scent impregnated or containing wax or similar material.
Using two or more layers with different scent dispersion characteristics or different scent dispersion profiles in a scent cartridge 106 may advantageously prolong the useful life of the scent cartridge. Where the respective scent dispersion profiles are inverse or at least somewhat complementary, such may advantageously result in a more uniform performance over the useful life of the scent cartridge 106. Further, using two or more layers with different scent dispersion characteristics in a scent cartridge 106 may advantageously reduce the amount of liquid scent or fragrance required to achieve a desired level of scent dispersion, thereby reducing or eliminating the possibility of leakage from the scent cartridge.
The first, the second, and any additional layers of scent media may be retained in a housing or retaining structure, for instance an annulus or ring structure having a perimeter or periphery. The housing or retaining structure may, for example, comprise a plastic or similar material. In particular, housing or retaining structure may comprise a material that is non-reactive to the scent media or fragrance (e.g., essential oils), and which forms a seal to prevent leakage from the scent cartridge 106. The first, the second, and any additional layers of scent media may be sandwiched or spaced between the selectively permeable membranes 110a, 110b, which may permit the passage of dry air therethrough but may be constructed to block the passage of moisture. For example, the selectively permeable membranes 110a, 110b may be made from hydrophobic or lipophilic woven or nonwoven material that inhibits the passage of moisture from the exterior environment to the interior and instead causes droplets of moisture to collect on an exterior surface of the selectively permeable membranes 110a, 110b. Due to the fact that materials having an affinity to fat (i.e., lipophilic materials) are typically water repellant, the selectively permeable membranes 110a, 110b may in many circumstances be composed of a material having lipophilic properties.
While generally described above as having two layers of two different types of scent media, a scent cartridge 106 may employ more than two layers of the two different types of scent media. Additionally, or alternatively, a scent cartridge 106 may employ more than two layers of more than two different types of scent media (e.g., three layers, one each of three different types of scent media). Some of the scent media may be passive, emitting scent without any particular stimulus, while some of the scent media may require activation via a particular stimulus (e.g., application of water, heat, vibratory motion) to emit scent.
As best illustrated in
As described herein, the scent dispensing device 100 may be worn on a biological body or attached to, mounted on or otherwise associated with an article of clothing or another object. The scent dispensing device 100 may, for example, be worn as a bracelet as shown in
The scent dispensing device 100 may be removably attached to an object in a variety of ways including use of a safety pin assembly. The safety pin assembly may be used to pin the device to the object. Furthermore, the scent dispensing device 100 may be removably attached by attachment to a grommet that is set in the object. A scent dispensing device 100c equipped with a safety pin assembly 120 is shown in
The deformablility of the scent dispensing device 100d, housing 102 thereof, ring or the grommet 126 enables releasable coupling of the scent dispensing device 100d to the textile 126 or other material in which the grommet 126 is set. For example, when the scent dispensing device 100d is engaged with the grommet 126, the application of force to the scent dispensing device 100d results in the release of the scent dispensing device 100d.
As shown in
As may be best viewed in
In various embodiments, the scent dispensing device 100 may also include an interface for facilitating communication with the scent dispensing device 100. For example, the interface may be electrical, optical or inductive, among others contemplated by those skilled in the art (e.g., electrical contacts or terminals). The interface, which may be wired or wireless, may be used for configuring the operation of the scent dispensing device 100. For example, the interface may be used to connect the scent dispensing device 100 to a computing device and carry data therebetween. The computing device may be used by a user to configure the operation of the scent dispensing device 100. Configuring the operation of the scent dispensing device 100 may include selecting the scent to be dispensed by the device or configuring an air flow through the scent dispensing device 100. The air flow may be adjusted such that to regulate the intensity of the scent emanating from scent dispensing device 100.
For example, the scent dispensing device 100 may be configured with a fan or an air jet, such as a synthetic air jet, among others. The fan or air jet may be positioned and selectively operable to cause a flow of air between the interior of the housing of the scent dispensing device 100 and the external environment so as to actively diffuse scent into the external environment.
In various embodiments, a selectively permeable membrane 110 of the scent dispensing device 100 may be constructed of fabric of another material. The fabric or material may be porous, whereby pores may have certain cross-sectional areas. The sizes of the cross-sectional areas may dictate the volume or rate of the scent emanating from the scent dispensing device 100, whereby as the size of a cross-sectional area decreases so does the volume or rate of the emanating scent. The sizes cross-sectional areas of the pores may be dynamically changeable based at least in part on electrical current supplied to the fabric of another material thus permitting changing a mode of operation of the scent dispensing device 100. For example, the scent dispensing device 100 may in an ‘off’ mode if the pore cross-sectional areas are reduced to a minuscule amount.
