## Abstract

The invention is a resealable package comprising a liquid and gas impermeable container with a resealable opening and a stack of wetted fibrous absorbent materials and particularly wet fibrous sheet material having interposed between the sheets of wetted absorbent materials at pre-determined intervals a liquid barrier layer. The liquid barrier layer is generally a thin flexible polymeric material which is impervious to the liquid used to wet the absorbent sheet material and is not reactable with the liquid or the absorbent sheet material.

## Claims

### Claim 1

A resealable package comprising:
a stack of wetted absorbent sheets;
a container formed by a liquid and gas impermeable material for holding said stack, said container including closure means for permitting access to said wetted absorbent sheets through an opening in said container and for resealing said opening; and
at least one liquid barrier sheet interposed in said stack between a predetermined number of wet absorbent sheets, each said liquid barrier sheet being detached from said container to provide gaseous communication between opposite sides of said liquid barrier sheet and each said liquid barrier sheet having opposite sides, with one side in contact with a first wetted absorbent sheet and the opposite side in contact with a second wetted absorbent sheet.

### Claim 2 (depends on 1)

A resealable package according to claim 1, wherein said liquid barrier sheet comprises a thin, flexible, liquid impervious film.

### Claim 3 (depends on 1)

A resealable package according to claim 1, wherein the liquid barrier sheet comprises a fibrous material having a fine mesh which is sufficiently small to prevent the passage of liquid from said wetted absorbent sheets therethrough.

### Claim 4 (depends on 1)

A resealable package according to claim 1, wherein said liquid barrier sheets are connected together along perforated fold lines and folded in an accordion pleated configuration along said perforated fold lines, with said predetermined number of wet absorbent sheets positioned between at least some adjacent folds of said liquid barrier sheet.

### Claim 5 (depends on 4)

A resealable package according to claim 4, wherein each said predetermined number of wet absorbent sheets are positioned between each pair of adjacent folds of said liquid barrier sheet.

### Claim 6 (depends on 4)

A resealable package according to claim 4, wherein said wet absorbent sheets are connected together along perforated fold lines and folded in an accordion pleated configuration along said perforated fold lines, and said accordion pleated configuration of wet absorbent sheets is positioned on one side of said accordion pleated configuration of liquid barrier sheets.

### Claim 7 (depends on 6)

A resealable package according to claim 6, wherein there is a second accordion pleated configuration of wet absorbent sheets positioned on the opposite side of said accordion pleated configuration of liquid barrier sheets.

### Claim 8 (depends on 1)

A resealable package according to claim 1, wherein each said liquid barrier sheet has a larger area than each said wet absorbent sheet.

### Claim 9 (depends on 8)

A resealable package according to claim 8, wherein each said web absorbent sheet is adhered to one said liquid barrier sheet.

### Claim 10 (depends on 1)

A resealable package according to claim 1, wherein said wet absorbent sheets are connected together along perforated lines to form a continuous sheet of wet absorbent sheets, and said continuous sheet is rolled to form a rope-like configuration.
