Abstract

Disclosed is a non-slip cotton sanitary pad, including a pad body, configured such that a cotton lining, an absorption pad and a waterproof cover are sequentially stacked, and a pair of wings protruding from both sides of the pad body, wherein the pair of wings protruding from both sides of the pad body includes a fastener so that the wings are fastened together in a folded state on the same surface, the cotton sanitary pad is disposed such that the waterproof cover contacts underwear, and the waterproof cover includes a non-slip member on the surface contacting the underwear.

Claims (27)

1. A non-slip reusable cotton-lined sanitary pad, comprising:

a pad body, configured such that a cotton lining, an absorption pad and a waterproof cover are sequentially stacked, and

a pair of wings protruding from both sides of the pad body,

wherein the pair of wings protruding from both sides of the pad body includes a fastener so that the wings are fastened together in a folded state on the same surface,

wherein a non-slip member is provided on an outer surface of the waterproof cover such that the non-slip member is disposed between the waterproof cover and an underwear,

the non-slip member is made of a silicone material, and is thermally fused to the waterproof cover,

the fastener includes buttons or hook-and-loop closures, and

the waterproof cover is subjected to polyurethane waterproof coating.

2. The non-slip reusable cotton-lined sanitary pad of claim 1 , wherein the non-slip member is formed on an entire surface of the waterproof cover, a pad body portion of the waterproof cover, or wing portions of the waterproof cover.

3. The non-slip reusable cotton-lined sanitary pad of claim 1 , wherein the non-slip member is thermally fused to the surface of the waterproof cover, the non-slip member being in a form of a single continuous layer, a discontinuous pattern layer, or a mixed layer in which a continuous layer and a discontinuous pattern layer are provided in compartments.

4. The non-slip reusable cotton-lined sanitary pad of claim 1 , wherein the cotton sanitary pad is a cotton sanitary napkin or a cotton urinary incontinence pad.

5. The non-slip reusable cotton-lined sanitary pad of claim 1 , wherein the cotton lining is positioned on an inner surface of the cotton sanitary pad.

6. The non-slip reusable cotton-lined sanitary pad of claim 1 , wherein the absorption pad is made out of a natural absorption material.

7. The non-slip reusable cotton-lined sanitary pad of claim 6 , wherein the natural material is cotton wool or cotton fiber.

8. The non-slip reusable cotton-lined sanitary pad of claim 1 , wherein the waterproof cover is made out of a sheet or fabric cloth subjected to the polyurethane waterproof coating.

9. The non-slip reusable cotton-lined sanitary pad of claim 1 , wherein the waterproof cover constituting the outer surface of the sanitary pad is formed so as to be the same size as the cotton lining.

10. The non-slip reusable cotton-lined sanitary pad of claim 1 , wherein the non-slip member composed of the silicone non-slip material has a higher frictional force with the underwear than with the waterproof cover.

11. The non-slip reusable cotton-lined sanitary pad of claim 1 , wherein the silicone non-slip member may further include rubber or polymer materials.

12. The non-slip reusable cotton-lined sanitary pad of claim 1 , wherein a central portion of the pad body including the absorption pad stacked under the cotton lining and the waterproof cover stacked thereunder are integratedly fixed through sewing or adhesion by the state of being sequentially stacked.

13. The non-slip reusable cotton-lined sanitary pad of claim 1 , wherein the absorption pad, cotton lining, and waterproof cover are integratedly fixed through sewing.

14. The non-slip reusable cotton-lined sanitary pad of claim 1 , wherein an outer circumferential surface of the sanitary pad is further sewn with a finishing material.

15. The non-slip reusable cotton-lined sanitary pad of claim 1 , wherein the cotton sanitary pad is free of adhesives or adhesive members comprising chemical components not limited to those commonly in double-sided tape.

16. The non-slip reusable cotton-lined sanitary pad of claim 1 , wherein the cotton sanitary pad is manufactured in a variety of sizes and shapes to suit the physical body size of the user and/or to suit the amount of absorbate by the user.

17. The non-slip reusable cotton-lined sanitary pad of claim 1 , wherein the cotton sanitary pad may be repeatedly reused after washing.

18. The non-slip reusable cotton-lined sanitary pad of claim 1 , wherein the buttons or hook-and-loop closures are positioned on a location on the wings to prevent vertical and lateral movement of the cotton sanitary pad.

19. The non-slip reusable cotton-lined sanitary pad of claim 18 , wherein the non-slip member further prevents the longitudinal movement of the cotton sanitary pad by creating a frictional force between the non-slip member and the underwear.

20. The non-slip reusable cotton-lined sanitary pad of claim 19 , wherein leakage of absorbate is reduced due to the combination of the buttons or the hook-and-loop closures, the wings, and the non-slip member, as compared to conventional, disposable sanitary pads.
