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.

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 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.

A volatile substance dispensing device (101) and method of fabrication thereof based on a container (201) sealed by a membrane layer (220) with at least one perimetral channel (103) which prevents lateral diffusion of the volatile substance during storage. The at least one perimetral channel (103) is at least partially filled with blocking means such as glue (303) or a protrusion (302) of a separation layer (230) produced by applying heat welding during fixation to the container (201). The dispensing device (101) further comprises a removable barrier layer (240) on top of the separation layer (230).

A device for diffusion of a liquid product, of the perfume type, stored in a reservoir includes at least one fixed part capable of being mounted on the reservoir, and offering at least one point of product supply by capillarity, the fixed part including a fixed porous body capable of being impregnated with product by capillarity by being directly immersed in the reservoir. The device also includes a nomadic element for each supply point, including a mobile porous body capable of being impregnated with product by capillarity while being in contact with the fixed porous body when the nomadic element is mounted on the fixed part. The nomadic element also includes a decorative structure of the jewel type, the mobile porous body being housed inside the decorative structure.

The invention refers to a device for evaporating volatile substances comprising: a container of a liquid volatile substance, and a vapour permeable membrane (1) and a thermoplastic porous or fibrous laminate (2) bonded together. Said container is closed at its opening by said vapour permeable membrane (1) and the fibrous laminate (2), wherein the fibrous laminate (2) is welded to the thermoformed part of the container.

A volatile composition dispenser includes a housing having an aperture and having opposing first and second walls that are joined along their peripheries to one another, where said second wall has a plurality of apertures; a volatile composition cartridge disposed within the housing between said first and second walls; and a gap, which exists between said volatile composition cartridge and a bottom surface of the housing, wherein said bottom surface is formed from a base portion of one or both of the first and second walls. Upon activation, the exposure percentage is greater than 40%.

A wick for a liquid electric vaporiser is disclosed. The wick comprises charcoal, inorganic minerals and water. Furthermore, the wick has a lower end and an upper end and is characterized in that the wick has a porosity between 24% and 44%, more preferably between 28% and 42%, and most preferably between 31% and 40% by volume. The wick exhibits a permeability between 3.2 and 9 mm per hour, more preferably between 3.8 and 8 mm per hour, and most preferably between 4 and 6 mm per hour, wherein the permeability is a measure of a vertical travel speed of a solvent liquid to travel from the lower end to the upper end of the wick by capillary action when the lower end of the wick is placed in a pool of the solvent liquid having a viscosity of between 1 and 10 cP, in particular between 1 and 4 cP, and a pool depth of about 2-4 mm. A liquid electric vaporiser including said wick is also disclosed.

Exemplary embodiments of a mister of the current invention comprise a reservoir, a spacer, and a dispenser assembly. A spacer fixedly joins the reservoir to the dispenser assembly a set distance. A liquid stored within the reservoir is configured to exit the reservoir at the valve through the spacer and impinge the dispenser assembly. The dispenser assembly includes a dispenser and a motor, the motor providing a rotational force for application to the dispenser. The dispenser presents an axis generally transverse to the liquid stream flow from the reservoir. Upon liquid stream flow impinging the rotating dispenser, the centrifugal force causes the liquid stream flow to spread radially from the dispenser to the air and/or surface in the target area, where it is dispersed outwardly over a target area, atomized or as droplets.

A dispensing screen for dispensing, by evaporation, volatile materials applied thereto, is provided. The screen comprises a sheet of material and diverting means formed in the plane of the sheet. The diverting means form a minimum path length along the length of the sheet between at least a portion of a first edge and an opposing second edge of the sheet, which minimum path length is longer than the distance between the first and second edges along the surface of the sheet. A dispensing apparatus is also provided, which in embodiments includes the dispensing screen of the invention, and in embodiments includes a sink for capturing un-evaporated volatile material.
