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.

Lighting fixture data hubs and systems and methods for use. An example of a data hub may include an annunciator configured to generate a first indication and a second indication, one or more sensors configured to detect between one or more vehicles and one or more pedestrians and potential convergence thereof within a zone in a vicinity of the data hub and to emit one or more signals corresponding to said detection, and a gateway in communication with an on-board processor and the annunciator, the on-board processor configured to wirelessly receive and analyze the one or more signals, communicate said one or more signals to the gateway so that the gateway can generate the first indication or the second indication in response to the one or more signals. Data hubs may also include a sensor unit housing and/or a light source.

Provided is an insect pest control product capable of effectively controlling flying insect pests. An insect pest control product comprising a thermal vaporization/diffusion absorbent wick for vaporizing and diffusing a water-based insecticidal composition containing a pyrethroid insecticidal component having a vapor pressure of 210.sup.4 to 110.sup.2 mmHg at 30 C., a glycol ether compound and/or glycol compound having a boiling point of 150-300 C., and water, wherein a concentration of the pyrethroid insecticidal component in diffused vapor particles one hour after the start of vaporization and diffusion is 1.5-18 times as high as a concentration of the pyrethroid insecticidal component in diffused vapor particles immediately after the start of vaporization and diffusion.

A dispensing system includes a substrate made of a porous material that defines a channel. The system also includes a base in contact with the substrate, A container for discharging a flowable medium into the channel is completely accommodated within the base and is partially exterior to the substrate.

Dispensers for fragrance and chemical compounds include paperboard materials and unique shapes to allow for simplified production and use of the dispensers in various environments.

A passive emanator 2 is described.

The passive emanator 2, especially for a fragrance, comprises a container 12 including a liquid composition 16 to be evaporated and emanated from the emanator via surrounding air, a porous wick 20 emerged in the liquid composition 16, and a porous membrane 18 arranged above a level of the liquid composition 16, wherein the membrane 18 is in contact with the wick 20 such that the membrane 18 is saturated with the liquid composition 16 via the wick 20 and an outer surface of the membrane 18 is in contact with the surrounding air. The liquid composition 16 includes a first solvent (especially DMM), a second solvent (especially DPM) and a fragrance or an insect repellent. The DMM and DPM are present in the liquid composition 16 at a weight ratio between 1:5 and 1:7, preferably 1:6, and most preferably 1:6.4.

A device for the release, in particular for evaporation, of volatile substances such as fragrances or active substances, has a container for a substance to be released. At least one wick as a capillary element is in contact with the substance to be released and at least partially in the receptacle and has a substance release region. The wick, preferably its substance release region, is assigned a heating element, preferably an electrical heating element. The wick is assigned a squeezing device with a squeezing element, by which a squeezing region of the wick can be subjected to a squeezing force and/or can be compressed, in particular for a defined short period of time and/or temporarily. A defined amount of substance, in particular at least the substance collected in the squeezing region, can be conveyed with a boost in the direction of the substance release region.

A device for dispersing in the air in the vapor state and a substance that is in the liquid state at ambient temperature, and is contained in a storage container, has a ventilation system with a duct that opens out into the open air and is configured to permit the passage of a flow of air into the duct; at least one dispensing unit is designed to be supplied with a liquid substance by the storage container, the dispensing unit having micro-ducts forming an outlet is provided in the duct in order to constitute an area of evaporation of the substance therein, and a heating unit is provided on or in the dispensing unit, such as to control a flow of the substance through the dispensing unit.

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.
