The present invention is directed to methods, compositions and articles comprising olfactory-active compositions. An article of the present invention comprises a structural component and an olfactory-active composition. The article may control the release, release rate or absorption of the olfactory-active composition. The article may be of various shapes and sizes. A method of use of an article comprises providing fragrance to an environment.

A volatile composition dispenser including a solid article having a volatile composition and a peripheral evaporative surface. The solid article shrinks relative to the peripheral evaporative surface from an initial size to a reduced size smaller than the initial size upon exposure of the solid article to the environment in an interior space. The solid article is characterized by a shrinkage in a direction away from the peripheral evaporative surface of greater than 1% to less than 40%. A visual indicator is located proximal to the peripheral evaporative surface of the solid article. The dispenser has a first configuration in which the visual indicator is not visually perceptible, and a second configuration in which the visual indicator is visually perceptible upon shrinkage of at least a portion of the solid article from the initial size to the reduced size for indicating a state of use of the dispenser.

A diffusion apparatuses comprising a decorative element, namely a bracelet, necklace or other like decorative element that may be worn by a user thereof, diffuses substances therefrom, specifically through one or more valves. The decorative element preferably comprises a reservoir having a substance to be diffused through a tube running through the decorative element, and configured to be diffused through the one or more valves on a surface of the decorative element. Methods of using the same are further provided.

A volatilization device and a storage device. The volatilization device comprises: a shell having a cavity, an air outlet communicated with the cavity being formed on the shell; and a color change member fixed on the shell. One side of the color change member is exposed to the cavity, the other side of the color change member can be seen from the outer wall of the shell, and the color change member changes color according to the concentration of a target gas in the cavity. The storage device comprises a box and the volatilization device, and the shell is fixed in the box. The color change member is fixed on the shell, one side of the color change member is exposed to the cavity of the shell, the other side of the color change member can be seen from the outer wall of the shell, and a user thus can determine, by observing the color change of the color change member, the validity of an item to be stored in the cavity, helping the user in in-time replacing.

An embodiment of the present disclosure may include a base for a scent warmer. The base may include a base member and a stem extending upwardly from the base member. The stem may be configured to carry a heating element thereon. The base may also include an elastomeric sleeve surrounding at least a portion of the stem. The elastomeric sleeve may be configured to apply a retention force between a removable decorative body and the stem. The elastomeric sleeve may include a wall member sized and configured to abut against the stem and a plurality of ribs extending radially outward from the wall member.

A display container for displaying an aromatic botanical specimen includes: (a) a container body for enclosing the botanical specimen and scented air having a scent of the botanical specimen; (b) at least one scent discharge port in the container body; and (c) an air pump coupled to the container body and operable to discharge the scented air from within the container body to the environment through the at least one scent discharge port.

The present invention relates to freshening compositions, devices comprising same and methods of using same for freshening the atmosphere, the air or surfaces. Also provided are methods for manufacturing the freshening compositions and devices comprising same. Disclosed are non-glycol ether liquid freshening compositions comprising a fragrance release modulator. A freshening composition of this invention may comprise (i) from about 0.1 wt % to about 95 wt % perfume raw materials, (ii) from about 0.01 wt % to about 90 wt % fragrance release modulator, and (iii) from about 1.0 wt % to about 95 wt % solvents, diluents or a mixture thereof. Disclosed are passive and active air or surface freshening products comprising a freshening composition of the present invention that allow controlled and customized release of the freshening composition to the atmosphere, air, or onto surfaces. The addition of a fragrance release modulator to formulate a freshening composition of the present invention allows the modulation of the release of the freshening composition.

As an accessory to cannabis and other smokers, an increased capacity, environmental and ecological friendly, sustainable solution personal air filter is disclosed. The solution effectively and efficiently combines passive filter medium and properties of fluid mechanics to achieve the increased capacity. Additionally, a specific order of passive filter elements is provided to increase filtering efficiency. Wherever possible, biodegradable materials are employed such a biodegradable PLA polymers.

A surface cleaning device includes a nozzle and an odor dial assembly. The nozzle includes a nozzle housing and a dirty air passageway. The odor dial assembly include a fragrance member and a dial body configured to be removably coupled to the nozzle housing. The dial body at least partially defines a fragrance cavity configured to at least partially receive the fragrance member and a fragrance passageway extending therethrough. The odor dial assembly is configured to transition between a plurality of user-selectable positions to adjust an amount of fragrance particles released by the fragrance member into the dirty air passageway.

An air treatment system is disclosed that includes a modular configuration whereby a fan module, filter module, and humidifier module may couple together to provide a plurality of air treatment solutions. In more detail, the modules can stack end-to-end in a vertical configuration. The modules may electrically couple to each other via a common electrical bus and enable a controller disposed in the fan module (or other module) to control fan flow rates, direction, and humidity. The fan module can include an articulating nozzle capable of directing airflow in virtually any direction and angle about an environment. The fan module can further include an inlet arrangement that can selectively restrict external air from entering the fan module housing when the fan module is fluidly coupled to the filter module. Thus, the fan module may generate air flow from exclusively filtered air to minimize or otherwise reduce bacterial/mold growth within the fan module housing.
