摘要:
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.
摘要:
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.
摘要:
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.
摘要:
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.
摘要:
Disclosed herein are devices for dispensing volatile vapors such as insecticides. Table-like carrier members provide a compartment for the volatile material. One or more table leg structures extend down from a table top to support a cavity in the table top a distance above a burner element. This results in more moderate and uniform heating, thereby permitting efficient release of the volatile material over a longer period of time. In some versions the table leg structures and table top are formed as separate pieces and designed to permit side-to-side ventilation under the volatile.

This invention relates to volatile insect repellent compositions comprising an insect repellent, such as deet, and specific maleic anhydride/alpha olefin polymers to increase the residual activity of the insect repellent.
摘要:
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.
摘要:
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.
摘要:
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.
