Abstract: Upper and lower contiguous sheets are bonded to each other at their outermost contiguous edges thereof to form an enclosure. The enclosure is divided into a plurality of sectional compartments isolated from each other by barrier sheets which are formed by bonding the upper and lower sheets in a conventional manner. Each sectional compartment contains a predetermined quantity of absorbent granules. The barrier sheets separating the compartments and at least one of the upper and lower contiguous sheets are dissolving paper fabricated of a water soluble carboxy methyl cellulose compound. In one embodiment both the upper and lower sheets are dissolving paper which dissolve together with the barrier sheets when the absorbent granules have absorbed a predetermined amount of moisture and/or liquid. The barrier sheets disintegrate to release the absorbent granules from each sectional compartment.

Abstract: Upper and lower contiguous filter sheets are bonded to each other at the outermost contiguous edges thereof to form an enclosure. The enclosure is divided into a plurality of sectional compartments which are isolated from each other by dissolving barrier sheets. The dissolving barrier sheets consist essentially of a water soluble carboxy methyl cellulose compound. Each of the sectional compartments contain a predetermined quantity of absorbent granules. The barrier sheets function to dissolve when the granules have absorbed a predetermined amount of moisture so as to provide for increased space in which to contain moist granules.
