A composition for an air freshener system including a 100% natural mixture of essential oil and one or more diluents that is adapted to have a longevity of between fifteen to forty days and include a flash point for the blend that is high enough that the blend remains effective for the desired period of time and slows the consumption of the essential oil and provides a consistent weight loss over the course of the air freshener system's consumption of the oil mixture.

An orientation independent delivery device. The delivery device includes a gas chamber, a delivery chamber, a gas cell, and a delivery aperture. The gas chamber includes a gas-side rigid portion and a gas-side flexible barrier. The gas-side flexible barrier is sealed to the gas-side rigid portion. The delivery chamber includes a delivery-side rigid portion and a delivery-side flexible barrier. The delivery-side flexible barrier is sealed to the delivery-side rigid portion and is oriented adjacent to the gas-side flexible barrier. The gas cell is coupled to the gas-side rigid portion of the gas chamber. The gas cell increases a gas pressure within the gas chamber to expand the gas-side flexible barrier. Expansion of the gas-side flexible barrier applies a compressive force to the delivery-side flexible barrier allowing a delivery material to escape from the delivery chamber.

Methods and apparatus are provided for activating a volatile dispensing device. The apparatus includes a puncturing mechanism formed between a first portion and a second portion of an activation arm and the puncturing mechanism being shaped to move laterally to puncture a volatile container as a compressive load is applied to the activation arm through the first and second portions.

There is a volatile composition dispenser comprising a housing comprising a rear frame having a frame opening, and an inner wall. A push button is movably disposed in the frame opening and the inner wall and is configured to be movable with respect to the inner wall from a first position to a second position wherein the push button is interlocked with the inner wall in the second position.

A volatile composition dispenser includes a housing having opposing first and second walls that are joined along their peripheries to one another. The first wall has an aperture and the second wall has a plurality of apertures. Within the housing, rests a volatile composition cartridge and a gap, which exists between the cartridge and a bottom surface of the housing, wherein said bottom surface is formed from a joinder of a base portion of one or both of the first and second walls, and wherein, upon activation, the exposure percentage of the dispenser is from about 40% to about 90%; wherein at least about 60% of the total surface area of the plurality of apertures results from individual apertures of said plurality that each have an area of at least 30 mm.sup.2 and an aspect ratio of at least about 1:2. Dispenser of a similar housing, cartridge, and gap when is activated by a user and thirty days after said activation, exhibits about 70% to 90% weight loss of said volatile composition of a partially exposed membrane of a fully exposed membrane.

There is a volatile composition dispenser comprising: a housing comprising a rear frame having a frame opening a push button movably disposed within the frame opening; and a cartridge aligned with the push button, the cartridge comprising a container having an orifice and containing a volatile composition, a rupturable substrate sealably attached to and covering the orifice, and rupture elements adjacent the rupturable substrate; and a resilient member aligned with the push button and the rupture elements wherein upon receiving a pressure on the push button, said resilient member moves the rupture elements into a first position in which the rupture elements engage with the rupturable substrate and wherein upon removing the pressure from the push button, said resilient member exerts a force on the push button and moves the rupture elements into a second position in which the rupture elements are not engaged with the rupturable substrate.

A volatile composition dispenser and methods of detecting the replacement of a cartridge of volatile composition are provided. The cartridge of the volatile composition dispenser includes one or more reservoirs, with each reservoir containing a volatile composition. A method of volatilizing the volatile composition includes operating the evaporative assistance elements with varying energy over a total emission program. Replacement of the cartridge by a user when the volatile composition dispenser is disconnected from an external power source is detected in order to reset the total emission program when reconnected to the external power source.

A diffuser includes a clip that attaches to a vent of a vehicle air conditioning system. The diffuser also includes a hollow scented body that emits a fragrance. The hollow scented body extends along a longitudinal axis and defines a cavity. The hollow scented body is mounted to the clip such that airflow from the vent is in a direction other than parallel to the longitudinal axis of the hollow scented body when the diffuser is attached to the vent.

A device including a receptacle that defines a neck. A liquid that impregnates diffusion means is housed inside the receptacle. The diffusion means includes a flexible band and a rigid band in contact with each other, the flexible band being in contact with the liquid inside the receptacle. The device also includes an inner closing element that fits tightly inside the neck and a regulation element complementary to the inner closing element. The rigid band is associated with the regulation element, the position of which determines the surface of the rigid band arranged on the outside of the receptacle. The device facilitates accurate regulation of the exposed surface of the rigid band, thereby regulating the intensity of the perfume in a room.

Described herein are compositions for malodor reduction in various air care applications.
