Abstract
A dispensing package for dispensing discrete portions of a vaporizable material in the form of prewetted absorbent pads, wherein the dispensing package broadly comprises a container and a plurality of such absorbent pads. The absorbent pads are closely stacked within the container, and generally comprise an absorbent pad portion with a flexible film backing which is resistant to permeation of the vaporizable material therethrough, and a collapsible tab- or ring-like structure joined to the backing opposite the absorbent pad portion. In other embodiments, the absorbent pad portion is preferably sub-divided into sub-portions having different fluid absorbing characteristics, which sub-portions are separated by the same flexible film as used in the backing, and less than all of the sub-portions are initially prewetted with the vaporizable material or are prewetted with different materials.
