The present invention relates to a deodorising composition containing: (a) 1,8-para-menthenethiol, (b) 3-mercaptohexyl acetate and (c) undecylenic acid or a derivative thereof. It also relates to the use of said composition for eliminating bad odours, and to a deodorant product in the form of an aerosol, a candle or a perfume diffuser that has a wick or a stick or is electric, or an article consisting of a solid polymeric material, in particular a silicone elastomer, containing the aforementioned composition.

Suggested is a rim block with improved scent performance, comprising or consisting of: (a) a solid rim block base, (b) at least one non-encapsulated perfume oil, and (c) at least one perfume oil same or different from component (b) encapsulated in a maltodextrin matrix.

The present invention relates to an evaporation retardant membrane for odorant compositions, which comprises a sheet-like support permeable to odorants, and at least one polymer coating arranged on one surface of the sheet-like support, wherein the sheet-like support is permeable to fragrances and where on at least one surface of the sheet-like support at least one polymer coating is arranged only on a part of the surface of the sheet-like support, such that the total coverage of the surface by all polymer coatings is 10 to 90%, and each quarter square centimeter of said surface is covered by a polymer coating to an extent of at least 10%. The present invention also relates to a device for controlled release of an odorant composition comprising a container for receiving an odorant composition, where the container has an opening, which is covered by the evaporation retardant membrane and the use of such a device for controlled release of odorant compositions.

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 freshener has a carrier with a pair of tabs defining a gap. A center tab extends from the pair of tabs and defines a longitudinal axis. At least one scented body is carried by one of the pair of tabs. The pair of tabs and the at least one scented body extend laterally with respect to the longitudinal axis of the center tab in opposite directions. The pair of tabs and the at least one scented body have a lateral width greater than a longitudinal depth.

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 sub stances 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.

An air enhancing device (1) for disseminating molecules and/or other substances into the air is disclosed comprising a base frame (5) configured to be fixedly mounted in a wall, panel, or furniture of a human accessible space, in particular in an in-wall box or an in-wall cavity in a wall of a building; a cartridge holder (7) attached to the base frame (5) and configured to receive a removable cartridge, the cartridge being designed to contain a fluid substance; and a fan and/or microblower configured to draw air into the air enhancing device (1) and expel air containing at least a portion of the substance out of the air enhancing device (1) into the human accessible space; and/or an emission module attached to the base frame (5) in fluid communication with the cartridge and configured to distribute a portion of the fluid substance into the air.

An odor control system for landfills includes a vapor device configured to generate an odor neutralizing chemical mixture, and at least one fan directed at a working face of a landfill. The at least one fan includes a fan housing having an inlet opening and a discharge opening connected by a passageway therethrough, a blade assembly positioned within the passageway of the fan housing and configured to rotate to generate an airflow from the discharge opening in a first direction, and a motor coupled to the blade assembly. The system includes at least one nozzle in fluid communication with the vapor device and proximate the discharge opening. The at least one nozzle is configured to disperse an odor neutralizing chemical vapor in the same first direction of the airflow from the discharge opening.

Described is a scent producing assembly having a self-contained module comprising an absorptive matrix infused with a volatile composition and a housing. The housing may include a receptacle shaped to receive the module, wherein the housing has a stowed position and a deployed position. In the stowed position, the receptacle may be contained within an interior of the housing. In the deployed position, the receptacle may be displaced out of the housing. The receptacle may move along an arcuate path when the receptacle is moved between the stowed and deployed positions.
