Abstract
Abstract A sanitary pad package (10) is disclosed which includes a backing sheet (12) and a sterilizable absorbant sanitary pad (18). A peelable adhesive (24) is provided to enclose the sanitary pad (18) when the backing sheet (12) is folded about the midfold line (26). The peelable adhesive (24) includes an adhesive coating (28) and a coating (30) having openings (32) therethrough exposing the backing sheet (12). The adhesive coating (28) is activated so that the coating (28) enters the openings (32) to adhere to the backing sheet (12).

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
217 words
A sanitary pad package comprising: a sterilizable, single layer backing sheet; a dry sterilizable absorbent sanitary pad secured on a first side of the backing sheet, the backing sheet extending beyond the edges of the sanitary pad, the backing sheet and sterilizable absorbent sanitary pad being sterilizable for use of the sanitary pad package within a sterile field; a continuous strip of peelable adhesive secured on the first side of the backing sheet and extending about the periphery of the sanitary pad so that the backing sheet can be folded to bring portions of the strip of peelable adhesive into facing relationship to form a continuous seal about the periphery of the sanitary pad to enclose the sanitary pad in the backing sheet so that the sterility of the sanitary pad can be maintained prior to enduring opening of the sanitary pad package, the peelable adhesive eliminating the need to tear the backing sheet to open the sanitary pad package, thereby reducing the time and effort needed to open the sanitary pad package while maintaining the sterility of the sterilizable absorbent sanitary pad; and strips of peelable adhesive secured on the opposite side of the backing sheet and the backing sheet is folded along intermediate fold lines outward from the continuous seal to form a compact package.

Claim 3
Dependent Claim
396 words
A sanitary pad package comprising: a generally rectangular sterilizable, single layer backing sheet of paper having first and second sides being foldable along a midline fold and first and second intermediate folds on either side of the midline fold; a dry sterilizable absorbent sanitary pad secured on a first side of the backing sheet and inside the intermediate fold lines, the backing sheet extending beyond the edges of the sanitary pad about the entire periphery of the sanitary pad, the backing sheet and sterilizable absorbent sanitary pad being sterilizable to permit the use of the sanitary pad package in a sterile surgical field, the backing sheet being fluid permeable to allow initial sterilization and resterilization of the sanitary pad package; a continuous strip of peelable adhesive secured on the first side of the backing sheet and extending about the periphery of the sanitary pad and between the intermediate folds so that the backing sheet can be folded about the midline fold to bring portions of the strip of peelable adhesive into facing relationship to form a continuous seal about the periphery of the sanitary pad to enclose the sanitary pad in the backing sheet so that the sterility of the pad can be maintained prior to and during opening of the sanitary pad package, the peelable adhesive on a first side of the midline fold being formed of an activatable adhesive coating, the peelable adhesive on the opposite side of the midline fold being formed by a second coating having a plurality of spaced openings therethrough exposing the first side of the backing sheet, the adhesive coating being activatable to enter the openings through the second coating and adhere to the first side of the backing sheet to form the continuous seal; and strips of peelable adhesive positioned at the outer edges of the backing sheet on the second side of the backing sheet and near the midline fold of the second side of the backing sheet so that as the backing sheet is folded around the intermediate fold lines, the outer edges are adhesively attached near the midline fold to form a compact package, the peelable adhesive avoiding the need to tear the backing sheet to open the sanitary pad package and thus reducing the time and effort needed to open the sanitary pad package while maintaining the sterility of the sterilizable absorbent sanitary pad.
