Claims

1. A sanitary pad comprising: (i) a lower cover layer 10 which includes a straight type body 11 and wing parts 12 formed at respective center portions on both sides of the straight type body 11 in a lateral direction thereof, and is made of a film material; (ii) an absorbent pad layer 20 whose both sides are separated from the lower cover layer 10 at a central portion of the lower cover layer 10 in a longitudinal direction of the lower cover layer 10 and only central portion is adhered to the lower cover layer 10, wherein a distal end portion thereof is divided into two hemispherical protrusions 21 and 22; (iii) an upper cover layer 30 laminated on the absorbent pad layer 20; and (iv) side cover layers 40 having a form in which both ends thereof extend from upper edges on both sides of the upper cover layer 30 to both upper end portions of the cover layer 10 in the lateral direction thereof, and middle portions thereof are inserted into a gap formed between the lower cover layer 10 and the separated both side portions of the absorbent pad layer 20 among the lower cover layer 10 and the absorbent pad layer 20.

DETAILED DESCRIPTION OF THE INVENTION

[0015] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0016] The sanitary pad according to the present invention is characterized by including: (i) a lower cover layer 10 which includes a straight type body 11 and wing parts 12 formed at respective center portions on both sides of the straight type body 11 in a lateral direction thereof, and is made of a film material; (ii) an absorbent pad layer 20 whose both sides are separated from the lower cover layer 10 at a central portion of the lower cover layer 10 in a longitudinal direction of the lower cover layer 10 and only central portion is adhered to the lower cover layer 10, wherein a distal end portion thereof is divided into two hemispherical protrusions 21 and 22; (iii) an upper cover layer 30 laminated on the absorbent pad layer 20; and (iv) side cover layers 40 having a form in which both ends thereof extend from upper edges on both sides of the upper cover layer 30 to both upper end portions of the cover layer in the lateral direction thereof, and middle portions thereof are inserted into a gap formed between the lower cover layer 10 and the separated both side portions of the absorbent pad layer 20 among the lower cover layer 10 and the absorbent pad layer 20.

[0017] Specifically, as shown in FIG. 3, the lower cover layer 10 forming the sanitary pad of the present invention includes the straight type body 11 and the wing parts 12 formed at the respective center portions on both sides of the straight type body 11 in the lateral direction thereof, and is made of a film material.

[0018] In addition, as shown in FIG. 4, the absorbent pad layer 20 forming the sanitary pad of the present invention has a configuration in which both sides are separated from the lower cover layer 10 at the central portion of the lower cover layer 10 in the longitudinal direction of the lower cover layer 10 and only the central portion is adhered to the lower cover layer 10, and is made of a non-woven material or a cotton pulp material, etc.

[0019] The absorbent pad layer 20 is characterized in that the distal end portion thereof is divided into the two hemispherical protrusions 21 and 22 so that the absorbent pad layer 20 reliably comes into close contact with a crotch portion of the human body of the wearer. In addition, a proximal end portion of the absorbent pad layer 20 is adhered to the lower cover layer 10 along an adhesion line 50. In the present disclosure, the “distal end” refers to a side which comes into close contact with the crotch portion (the right side in FIG. 3), and the “proximal end” refers to a side opposite thereto (the left side in FIG. 3).

[0020] The upper cover layer 30 forming the sanitary pad of the present invention is laminated on the absorbent pad layer 20, and is made of a non-woven material or a mesh film material, etc.

[0021] The side cover layers 40 forming the sanitary pad of the present invention are made of a non-woven material or a mesh film material, and have a form in which the both ends thereof extend from the upper edges on both sides of the upper cover layer 30 to the both upper end portions of the cover layer 10 in the lateral direction thereof, and the middle portions thereof are inserted into the gap formed between the lower cover layer 10 and the separated both side portions of the absorbent pad layer 20 among the lower cover layer 10 and the absorbent pad layer 20.

[0022] The present invention is characterized in that the both side portions of the absorbent pad layer 20 wrapped with the side cover layers 40 are separated from the lower cover layer 10.

[0023] The both side portions of the absorbent pad layer separated from the lower cover layer 10 play a role of a barrier membrane to minimize the gap between the sanitary pad and the human body, thus to prevent the menstrual blood leaking to an outside by increasing the contact area with the human body, even if the lower cover layer 10 attached to the underwear is moved away from the human body due to a movement of the wearer of the sanitary pad.

[0024] According to the present invention, both side portions of the absorbent pad layer 20 are separated from the lower cover layer 10, and then the separated both side portions are wrapped with the side cover layers 40. Therefore, even if the lower cover layer 10 attached to the underwear is moved away from a human body due to a movement of a wearer of the sanitary pad, the absorbent pad layer 20 reliably comes into close contact with a crotch portion of the wearer by increasing a contact area with the human body. In addition, the distal end portion of the absorbent pad layer 20 is divided into two hemispherical protrusions 21 and 22, and the lower end portion of the sanitary pad is formed in a form that is folded depending on a difference in the thickness, thereby it is possible to effectively prevent the leakage of menstrual blood by increasing a degree of adhesion of the sanitary pad in accordance with a curved surface of the human body.
