Embodiment Construction

[0025] The present invention relates to a wick-based delivery system for delivering liquid from a storage container to a surface exposed to ambient air. In its simplest form, the system of the invention comprises a container for holding liquid and a wick for delivering liquid from the container to the upper surface of the wick.

[0026] Containers can be in a variety of shapes. For example, in figure 1 In, the container is a bottle 1 of conventional shape. Bottle 1 is filled with a vaporizable liquid. ( figure 1 The liquid level is not shown. ) A siphon core 3 should be shaped so that it fits tightly into the neck 5 of the bottle 1 . Preferably using a method such as figure 1 The neck closure 2 shown in , to hold the wick 3 in place and prevent leakage around the neck 5 of the bottle 1 . The bottle neck closure 2 and the bottle 1 should be tightly installed to prevent liquid from leaking from the bottle 1 . Similarly, the fit between the neck closure 2 and the wick 3 s...

Abstract

A wick-based delivery system includes a container for holding a liquid. The container has an opening at its top surface and is non-vented. A porous wick, having a predetermined mean pore size of less than about four microns, and preferably less than about one micron, extends through the opening in the container. When the liquid is added to the container, a lower region of the porous wick is in contact with the liquid and an upper region of the porous wick is exposed to the ambient air. The opening in the container is also substantially sealed by the insertion of the porous wick.

Description

technical field [0001] The present invention relates to a device for delivering a liquid, such as an insect repellent, fragrance or insecticide, from a storage container to a surface exposed to ambient air. Background technique [0002] Devices for releasing vapor into the surrounding air are well known in the art. Typically, the purpose of these devices is to deodorize or disinfect the surrounding air, or to emit a toxin into the air to kill or repel unwanted pests, such as mosquitoes. [0003] Several methods have been used to achieve the goal of distributing steam into the air. For example, an aerosol container is used to spray steam into the air when a trigger is activated by the user. However, other methods utilize the evaporative properties of liquids or other evaporable substances or other evaporable materials to cause diffuse distribution of vapors into the ambient air that produce the desired properties. Another such method of evaporation utilizes a wick to deliv...
