The device for the diffusion of volatile substances comprises a container (1), which holds a liquid with the volatile substances in it, and which has an opening (9), for communication from the inside of the housing (6) to the outside; a cover (2) which can be attached to the container (1) to close the opening (9), a diffusion wick (4) for the controlled diffusion of the volatile substances, one end (13) of which protrudes from the cover (2); and a cap (5) which covers the end (13) of the diffusion wick (4) which protrudes from the cover (2), the container (1), the cover (2), the diffusion wick (4) and the cap (5) being made of the same plastic material. It thus makes it possible to provide more efficient recyclability in accordance with currently existing methods.

An aqueous dispersion, an aqueous coating composition comprising the aqueous dispersion, and coatings made therefrom capable of slow release of fragrance.

A composition may include microcapsules containing at least one odor-neutralizing agent, and agents may include such a composition. Furthermore, such compositions or agents may reduce malodors and/or be used for treating a surface, for treating room air, or for washing and/or caring for textiles using such compositions or agents.

An air freshener includes a first arm and a second arm connected together at one of their ends by a joint to enable swinging of the arms between an open configuration and a closed configuration. In a closed configuration, a fastener clasps opposite ends of the first arm and the second arm together to surround a central space in which a support structure, such as a support post of a rearview mirror on a vehicle, may be positioned. The first arm and the second arm each include an inner wall and lateral side walls defining an open chamber in which a fragrance substrate is retained by an interference fit. The inner wall defines an interior periphery, and ends of the lateral side walls define an exterior periphery of the air freshener.

Disclosed is a volatile liquid dispensing system that includes a dispenser and a refill unit. The dispenser is mounted on a predefined surface. The dispenser includes a front cover and a rear cover. The refill unit is removably secured inside the dispenser thereby maintaining a predefined gap therebetween. The refill unit includes a refill cover. The refill cover includes a fragrance reservoir and a collection device enclosed therein. The fragrance reservoir is formed by a gas shell and a fragrance shell. The fragrance reservoir is positioned in a predefined orientation with respect to the mounting surface. The collection device is positioned adjacent to the fragrance reservoir such that a predefined gap is maintained therebetween. The collection device is enclosed in the refill cover such that a predefined gap is maintained therebetween thereby allowing evaporation of the volatile liquid from all sides of the collection device.

An adhesive device is capable of releasing fragrances, specifically scent patches. The adhesive device is used in the treatment of side effects associated with incontinence or an ileostomy.

A scent dispenser/absorber includes a container, an invertible lid reversibly attached to an open end of the container, a vented cage, and a scent cartridge housed within the cage after being procured from a repository or so-called “scent library.” In an “off” condition or state, the scent cartridge/cage combination is received in an interior chamber of the container, where the scent cartridge is out of communication with the surrounding environment and therefore incapable of performing scent dispensing or absorbing functions. The scent dispenser/absorber can be switched to an “on” condition or state by manually inverting the lid and hence the associated cage/scent cartridge combination such that the scent cartridge can be positioned externally of the container, where it can communicate with the surrounding environment to perform a desired scent dispensing or absorbing function. In an “on” condition, scent molecules originating from an odorant contained in a reticulated, hydrophilic inner core of the scent cartridge pass through a thermoplastic outer skin of the scent cartridge before being diffused into the surrounding environment.

A scent producing assembly includes a self-contained module comprising an absorptive matrix infused with a volatile composition and a housing. The housing includes a receptacle shaped to receive the module, at least one energy source (1004), such as an electrically heated plate, and at least one air gap (2062) located between the energy source and the receptacle. Heat from the energy source is transferred to air within the at least one air gap and to the module, which creates a draft through the at least one air gap that enhances release of the volatile composition from the heated module.

Described are articles formed of a pulp base material comprising fibers, wherein pores are formed between the fibers. A volatile composition with at least one top note component and at least one base note component at least partially fills the pores of the pulp base material. A release rate of the at least one top note component is modulated by the pulp base material, and a release rate of the at least one base note component is enhanced by the pulp base material.

Methods, systems, and devices are disclosed for implementing switchable dispensing and/or delivery of scented substances. In one aspect, a device includes a cartridge structured to include one or more chambers containing one or more scented substances contained in a corresponding chamber, a housing structured to include a compartment to hold the cartridge, an opening to allow the scented substances to dispense to an outer environment from the device, and one or more transporting channels formed between the compartment and the opening, in which each of the one or more transporting channels is configured to accelerate a scented substance from the corresponding chamber to the opening, and an actuator switch arranged in a corresponding transporting channel and operable to move between an open position and a closed position based on an applied signal to selectively allow passage of the scented substance from the corresponding transporting path.
