The invention described herein is a framed fluid delivery device that is made up of a fluid-delivery cartridge for the timed-release delivery of a fluid contained therein, and a frame assembly for retaining the fluid delivery cartridge. The frame assembly is made up of a base portion that facilitates the delivery of fluid released from the fluid-delivery cartridge, at least one side panel associated with the base, and that secures the fluid-delivery cartridge within the frame assembly proximate the released fluid delivering means. Additionally, a fluid delivery device is disclosed that includes a fluid-delivery cartridge for the timed-release delivery of a fluid contained therein, the cartridge having a bottom, a top, and sides, and a dispersion pad positioned proximate the bottom of the fluid-delivery cartridge, wherein the dispersion pad at least partially surrounds the sides of the fluid-delivery cartridge.

1. Field of the Invention
The present invention relates generally to the delivery of volatile liquids over a period of time to a surrounding area of space, and particularly to structures capable of retaining a fluid delivery device capable of releasing a fluid over time, and facilitating the improved release of volatile liquids therefrom.
2. Background Art
FIG. 1 comprises a perspective view of a fluid delivery system as substantially described herein;
FIG. 2 comprises a perspective view of a frame assembly as described herein;
FIG. 3 comprises a perspective view of an alternative embodiment of the frame assembly;
The present invention is shown and described herein as a framed fluid delivery device that, at a minimum, has a fluid-delivery cartridge for the delivery of a fluid contained therein over a period of time, and a frame assembly for retaining the fluid delivery cartridge, comprising means for securing the fluid-delivery cartridge within the frame assembly. The frame enables the cartridge to be securely retained within the frame assembly for easy handling and storage.
Preferably, the frame assembly consists of a base portion having a means for facilitating the delivery of fluid released from the fluid-delivery cartridge, and at least one side panel, but preferably at least two side panels, associated with the base, wherein the securing means secures the fluid-delivery cartridge proximate the released fluid delivering means. The side panels may also have leg extensions depending therefrom. The side panels may be either hingedly or fixedly associated with the base portion. If the side panels are hingedly attached, they enable the frame assembly to begin from a substantially planar position and to be folded upward into its final shape or position.
The base portion is preferably a substantially planar piece having one or more sides. For example, the base portion could be circular, oval, rectangular, square, triangular, pentagonal, or any other two dimensional shape. Additionally, depending up on the shape, it is preferred that the at least two side panels comprise a number of side panels equivalent to the number of sides of the base portion plane.
