B. KASOFF SANITARY NAPKIN ot..417, 195o Filed Jan. 26, 1949 Patented Oct. 17, 195() UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to sanitary napkins and has for its object to provide in a manner as hereinafter set forth a structure for absorbing menstrual discharges without soiling the clothing.

A further object of the invention resides in the provision of a sanitary napkin which has a maximum amount of absorptive capacity Without increasing the discomfort of the wearer.

A further object of the invention resides in the provision of a sanitary napkin having means therein to prevent the penetration of moisture therefrom to the garment or garments of the wearer.

Another object of the invention resides in the provision of a sanitary napkin which is simple in construction and arrangement, thoroughly enicient for its intended use, soft, pliable, comfortable and having a minimum of bulk, and which may be conveniently carried in the pocket or purse for emergency and which is comparatively inexpensive to manufacture and convenient for destruction after use.

These objects and other incidental ends and advantages of the invention will hereinafter appear in the progress of the disclosure and as pointed out in the appended claim.

Accompanying this specification is a drawing in which:

Figure I is a view in perspective of the complete and assembled sanitary napkin.

Figure 2 is a view in perspective showing parts of a napkin in position prior to the iinal folding operation.

Figure 3 is a sectional view of Figure 1, along the plane 33 thereof.

Figure i is a sectional view of Figure 1 along the plane 4 4 thereof.

In accordance with the invention and the preferred form shown, the body of the napkin I may be composed of any suitable absorbent material such as cotton layers, paper in-sheet form or any other cheap and soft absorbent material. As shown, the napkin body is composed of a core of a plurality of layers or plies which make up the core and is indicated by numeral I2. Any desired number of layers may be employed to produce the necessary thickness.

A casing for core I2 made of any absorbent and soft material such as crepe paper is provided and may be of more than one ply as indicated by numeral I 3. Casing I3 in the form of a sheet is adapted to be Wound about core I2 longitudinally thereof to encase the core I2 and maintain said core in shape.

To provide one side of core I2 waterproof, a liner I6 is shown and is adapted to be held in place frictionally.

Thus, the core I2 and the casing therefor are encased in an envelope such as cheese-cloth I5. As shown, the liner consists of a rectangular sheet of water-proof material I 6 such as rubberized cloth, plastic, sheet rubber, oil cloth, oil silk or paraiin treated fabric and as shown in Figure 3 is placed against one of the walls of core I2 and maintained in place by folding casing I3 and envelope I5 thereover.

Figures 1, 3 and 4 show the liner I6 as being placed between casing I3 and cloth I5, the latter having over-all dimensions so that when folded, the longitudinal edges overlap over liner I6 and the doubled or multiple ply edges I5a are foldable toward each other as shown in Figure l.

Thus a napkin has been provided which prevents possibility of fluid passing therethrough. It is to be observed that the napkin above-described may be cheaply manufactured and at the same time affords the comfort and the protection required of the device.

I wish it understood that minor changes and variations in integration, location, material and duplication of parts may all be resorted to Without departing from the spirit of the invention and the scope of the appended claim.

I claim:

A sanitary napkin comprising a thick elongated core of soft absorbent material, said absorbent core having opposite flat faces and long side edges, a thin absorbent casing sheet wrapped about the faces and side edges of the absorbent material and having the edges thereof overlapn ping one another above one of the fiat faces, a thin, pliable and water proof liner extending along the overlapped edges of the casing sheet and interposed between the flat face of the core and said edges of the casing, a cheese cloth strip enveloping the core, casing sheet and liner to hold the same in assembled relationship.
