A refill for holding at least two compositions comprises a container including a body and first and second compositions disposed within the body such that the first and second compositions are substantially separated and the second composition is disposed above the first composition. The refill further includes a tube disposed within the body of the container such that the tube contains the first and second compositions, wherein the tube has an inner diameter and an outer diameter. Still further, the refill includes a wick disposed within the tube, wherein the wick contains the first and second compositions and has a diameter that is smaller than the inner diameter of the tube to create a gap between the wick and the tube is smaller than the inner diameter of the tube to create a gap between the wick and the tube.

The device for diffusing volatile substances comprises means for generating an air stream, and is characterized in that said means for generating an air stream comprise a flexible sheet (1) and at least one piezoelectric element (2), such that said piezoelectric element (2) causes said flexible sheet (1) to expand and shrink to generate the air stream. It allows generating an air flow that is adapted to the geometry of the evaporation surface.

A clasp hanger includes a hanger hook including an elongated part. The hanger hook has a hanger hook section and a neck section opposite the hook section. The neck section is expandable to allow the clasp hanger to be quickly hung on a support object such as a branch. The clasp hanger further includes an object attachment device attached to the neck section of the hanger hook. This object attachment device is configured for attaching an object such as one configured to dispense a chemical or formulation useful in pest management. The hanger hook, and object attachment device are disposed such that, after the support object is pushed through the neck, the hanger hook automatically rotates such that the support object is disposed at an interior part of the hanger hook that is away from the neck section. This prevents the support object from passing back through the neck section.

Disclosed herein is a clasp hanger for hanging. The clasp hanger includes a hanger hook comprised of an elongated part. The hanger hook has a hanger hook section and a neck section opposite the hook section. The neck section is expandable to allow the clasp hanger to be quickly hung on a support object such as a branch. The clasp hanger further includes an object attachment device attached to the neck section of the hanger hook. This object attachment device is configured for attaching an object to be hung. The object may be, for example, configured to dispense a chemical or formulation useful in agricultural pest management. The hanger hook, and object attachment device are disposed such that, after the support object is pushed through the neck, the hanger hook will automatically rotate such that the support object is disposed at an interior part of the hanger hook that is away from the neck section. This prevents the support object from passing back through the neck section.

A volatile material dispenser may include a housing adapted to hold a refill containing a volatile material and a nebulizer in communication with the refill and the volatile material within the refill, wherein the nebulizer is adapted to volatilize and emit the volatile material as nebulized particles. The nebulizer may include a piezoelectric element having a central aperture and first and second opposing surfaces and an orifice plate disposed adjacent the first surface of the piezoelectric element.

Micropores penetrating a vibration plate 12 in a thickness direction thereof are formed, in which the vibration plate 12 atomizes a solution by vibration of a piezoelectric vibrator 11 that generates ultrasonic vibration when current is applied thereto. In addition, the spraying time and the spraying interval time are controlled by turning on or off the current applied to the piezoelectric vibrator 11, such that a value of [50% particle diameter of spray particles in cumulative volume distribution]([spraying time]/[spraying interval time]) becomes 0.2 to 2.5 m.

A portable and compact mist emitting device for disperse a fluid mist into a target surrounding space. The mist emitting device includes a bottom housing having a recessed portion adapted to receive a replaceable fluid reservoir storing a liquid, a liquid conveying member having a first end positioned in the fluid reservoir and a second end extending from the recessed portion in a direction away from the fluid reservoir. The liquid conveying member conveys the liquid stored in the fluid reservoir towards the second end by capillary action. An atomizer is coupled with the liquid conveying member to convert the liquid present at the second end of the liquid conveying member into mist particles.
