Volatile impregnated substrates, such as wicks and mats, that can be used in a dispensing device that uses a heat source or otherwise uses active means to promote the release of the volatile material from the substrate are disclosed. The preferred substrate has a structure including sand particles adhered together by a binder to form a network of pores and passages. The binder is selected from thermoset polymeric materials and mixtures thereof. A volatile material is disposed in the pores before the substrate is installed in the dispensing device. The impregnated substrate is positioned in the dispensing device on or near the heat source of the dispensing device. The heat source is activated thereby elevating the temperature of the substrate such that volatile material is released from the pores. In one embodiment, the sand particles comprise silica sand and the binder is a cured novolac resin.

Substrate for volatile delivery systems

Aerosol insecticidal sprays are disclosed that contain butylhydroxytoluene, limonene, and sodium benzoate, in addition to water, hydrocarbon solvent, propellant, surfactant, and insecticidal active. The sprays are resistant to discoloration even during long term storage.

Aerosol spray resistant to discoloration

A pressure resistant plastic bottle for containing and dispensing an aerosol composition. The plastic bottle is designed to reduce deformation by a local reinforcement to the neck and shoulder regions. The reinforcement preferably comprises the provision of a wall thickness for a lower portion of the neck as compared to the wall thickness of the upper portion of the neck to be increased by a ratio of from about 1.25:1 to about 2.5:1.

Pressurized plastic bottle with reinforced neck and shoulder for dispensing an aerosol

Disclosed herein are mats for dispensing volatile materials. A mat of the present invention includes a moat on an upper surface of the mat defining a first mat portion and a second mat portion, preferably connected at the bottom of the moat. Both portions are impregnated with the same or different volatiles. The moat is formed by pressing the upper wall of the mat with a hot forming die. While pressed against the upper wall, the hot die melts the mat material leading to the close of the pores in the material and as a result, a barrier along moat walls is formed. The moat and barrier act to prevent or reduce bleeding of the volatiles between two portions of the mat. The mat provides for both instant burst of volatile and then a sustained vaporization of volatile. Methods for making and using the mat are also disclosed.

Multi-stage dispensing mat

A pressure container comprising axially extending side walls formed of plastic extending between a top end and a bottom end. A metal top is attached at a top seam in pressure-containing relation to the top end of the side walls, and a metal bottom attached at a bottom seam in pressure-containing relation to the bottom end of the side walls. Optional top and bottom beads are formed in the side walls to aid in sealingly securing the metal top and bottom to the side walls. A method for containing pressurized materials by providing and filling such a pressure container is also shown.

Mat for dispensing a volatile

A nozzle insert, and/or an actuator nozzle structure, for use in dispensing a material to be dispensed from an aerosol can. The nozzle insert or actuator nozzle structure divide the spray of dispensed material into two independent, simultaneously emitted aerosol streams, which may have different attributes and may be emitted in different directions. One stream may be an upwardly directed fogger stream and the other stream may be a forwardly directed, aimable stream. This permits a user to direct, for example, an insecticide at a particular target, while simultaneously more generally fogging an area of interest.

Aerosol dispensing nozzle

A time duration of end of product life indicator is disclosed which utilizes a volatile dye coated or impregnated into a substrate or carrier. The dye evaporates as a volatile component of the product evaporates thereby changing the color of the substrate or carrier. The consumer is alerted to the depletion of the volatile component of the product when the substrate or carrier changes from a colored or dyed state to an uncolored state. As a result, a visual time duration or end of product life indicator is provided.

End of use and time duration indicator system and method based on volatile dye

Disclosed herein is two-stage mat for dispensing volatile materials. The mat is comprised of two materials varying either in thickness, thermal conductivity and/or porosity (and coated with like volatile material), or coated with volatile materials having different vaporization pressures. In either configuration, the mat provides for both an instant burst of volatile and then a sustained vaporization of volatile. Methods of using such mats are also disclosed.

Two-stage dispensing mat

An insect coil having an extended, burnable body. The body has multiple treated zones bearing a volatilizable insect control active ingredient at insect controlling levels separated by spacing zones bearing a level of insect control active ingredient lesser than that of the treated zones. When burned, the insect coil releases bursts spaced in time of the active ingredient in insect controlling quantities. Preferably the spacing zones are active ingredient free, and the first treated zone to be burned has an active ingredient level higher than the remaining treated zones. A method of controlling insects by use of the insect coil also is disclosed.

Insect coil

Disclosed herein is an article (such as an insect control pouch) to dispense a volatile active (such as an insect control agent). The pouch is formed from a single layer polymeric non-absorbing film. The pouch traps the active until use of the pouch is desired. When the pouch is opened the walls of the pouch serve as a substrate from which the active can readily passively evaporate. Methods of forming such pouches using heat sealing techniques, and methods of using such pouches, are also disclosed.

Insect control pouch

Disclosed herein are mats for dispensing volatile vapors such as insecticides. The mats are multi-layered. One layer is a carrier layer impregnated with the volatile. It is secured to at least one metal layer. The metal layer spreads the heat from a heater, thereby minimizing hot spots. In other embodiments additional layers are provided to provide a further heat distribution or temperature step down. An air gap can be provided between two of the layers.
