A hollow container is combined with a burstable envelope retaining a liquid agent. The container is designed to allow a user to open the envelope by bursting or likewise rupturing the envelope while it remains in the container. The design of the envelope provides a predictable bursting location and a lower bursting pressure of the envelope to provide a more controlled release of liquid agent. Bursting forces may be applied in any of a variety of ways just as by twisting or crushing. The design allows for desired use of beneficial envelope materials such as polyester films that are otherwise difficult to rupture.

A dispenser is disclosed. In one example, the dispenser relates to the distribution of formic acid vapour in beehives to combat mites. The dispenser has an evaporation surface which is delimited by a thin, gas-permeable, highly porous membrane made from a hydrophobic material and comprises an evaporation container and a reservoir, for the treatment dose of a liquid formic acid preparation. The evaporation container can be placed in a narrow air space of the hive, for example a comb space. The evaporation surface is exposed in a comb space of the brood nest or an air flow path. In one embodiment, the dispenser is equipped with a stackable packaging, and the treatment dose of the formic acid preparation is located exclusively in the hermetically sealed reservoir. The dispenser allows a very high evaporation rate per unit area and can be used without spatially extending the hive.

A device has a container for a substance to be dispensed. A wick as a capillary element in contact with the substance in the container and forms part of the container. The wick has a wick-side substance dispensing area. A heating element produces a substance air flow, which is enriched with substance and flows away from the device, by heating the wick-side substance dispensing area and a substantially substance-free hot air flow that flows away from the device and is warmer than the substance air flow, by heating the air surrounding the heating element. A flow-guiding and/or deflecting apparatus guides and/or deflects at least one of the air flows, preferably the substance-free hot air flow, such that the air flows hit each other, preferably at a defined angle of incidence, and form a common substance-and-hot-air flow flowing away from the device.

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 fire pit has a gas burner and a repellent container. The gas burner provides energy that volatilizes repellent from the repellent container.

A volatile material dispenser includes a base and a stand assembly that is coupled with the base. The base includes a fan and a battery therein. The stand assembly includes a platform, a stand that extends from the platform, and a manifold that extends from the stand. The volatile material dispenser also includes a shroud and an air deflector. The shroud is positioned on the base and defines a chimney. The air deflector is positioned between the shroud and the manifold. The air deflector is configured to direct air out of the chimney.

An insect repellent device has a housing that fits onto a liquid repellent reservoir. The housing may have a heater for volatilizing the liquid insect repellent.

A volatile material dispenser comprises a base that houses a printed circuit board. The base includes at least one button and a plurality of visual indicators along a front portion. The volatile material dispenser further comprises a stand assembly that is coupled with the base. The stand assembly includes a platform defining a front portion and a rear portion, a stand that is disposed above and on the rear portion of the platform, a manifold that is disposed at an upper end of the stand and defines an outer side surface from which extends a plurality of radially spaced ribs, and a piezoelectric assembly disposed within the manifold. The volatile material dispenser further comprises a cover that is configured to be attachable to and detachable from the base. The cover defines a chimney that defines a longitudinal axis. The manifold includes a refill chassis.

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.

The present invention relates to a device and a method for immobilizing and identifying pests. The present invention also relates to a device that can be filled with fluid to immobilize pests, means making sure that the level of the fluid in the device stays within defined limits.
