A fragrance delivery system comprising at least one cartridge containing solid elements loaded by adsorption of an olfactory composition and opened by a grid having holes, the cross-section of which is smaller than the cross-section of the solid elements, wherein the solid elements are made of a polymer ensuring a natural delivery of the fragrances for a period of 6 to 18 months, and in that the cartridge is mounted on a cartridge holder holding the cartridge and connected to a mounting base on a fixed portion by an unstable linkage capable of ensuring an oscillating movement of the cartridge holder around a reference position.

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.

A fragrance compound impregnated porous carrier enclosed within an envelope where a tear initiating feature of the envelope is aligned with a trimmed portion of the porous carrier, to thereby prevent a tear in the envelope from inducing a tear in the porous carrier.

A fragrance delivery system comprising at least one cartridge containing solid elements loaded by adsorption of an olfactory composition and opened by a grid having holes, the cross-section of which is smaller than the cross-section of the solid elements, wherein the solid elements are made of a polymer ensuring a natural delivery of the fragrances for a period of 6 to 18 months, and in that the cartridge is mounted on a cartridge holder holding the cartridge and connected to a mounting base on a fixed portion by an unstable linkage capable of ensuring an oscillating movement of the cartridge holder around a reference position.

A multi-layer article including a first non-active state and a second active state, the multi-layer article comprising an outer layer having a first side and a second side, an inner layer adjacent to at least a portion of the outer layer and including a volatile material, and an upper layer including a first side and a second side, the first side of the upper layer being adjacent to at least a portion of the inner layer. The multi-layer article is folded upon itself in the first non-active state so that at least a first portion of the second side of the upper layer is disposed on a top of a second portion of the second side of the upper layer, and the first portion and the second portion of the upper layer are heat sealed in the non-active state.

Microporous materials that include thermoplastic organic polyolefin polymer (e.g., ultrahigh molecular weight polyolefin, such as polyethylene), particulate filler (e.g., precipitated silica), and a network of interconnecting pores, are described. The microporous materials of the present invention possess controlled volatile material transfer properties. The microporous materials can have a density of at least 0.8 g/cm.sup.3; and a volatile material transfer rate, from the volatile material contact surface to the vapor release surface of the microporous material, of from 0.04 to 0.6 mg/(hour*cm.sup.2). In addition, when volatile material is transferred from the volatile material contact surface to the vapor release surface, the vapor release surface is substantially free of volatile material in liquid form.

A volatile medium delivery system, comprising a housing, a barrier element engageable with the housing, and a substrate having a volatile medium absorbed therein, wherein the substrate is engageable with the housing and positionable with respect to the housing to control a predetermined release rate of volatile medium to an external environment.

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.

The volatile substance diffuser comprises a support (1) impregnated with the volatile substances, wherein at least one portion of the volatile substances is contained in at least first microcapsules (2) and second microcapsules (3) comprising a core (10) and a coating (11), the diffusion times of the first and second microcapsules (2, 3) being different to each other.

It enables the diffusion time of the volatile substances to be increased.

The present invention relates to a bracelet for the diffusion of volatile substances, comprising a strap (1) and a refill (2) impregnated with volatile substances, and is characterized in that the refill (2) comprises an outer surface (21) provided with at least one rib (3), defining at least one evaporation chamber (4).

The present invention provides a bracelet for the diffusion of volatile substances having a higher volatile substance evaporation rate, with the refill having a size that is suitable for use in a bracelet and being firmly secured on the strap, even in bracelets for children.
