Description

Three dimensional shape sanitary pad}

The present invention relates to a sanitary napkin used by women, and more particularly, to a three-dimensional sanitary napkin in which an elastic guide sheet member for preventing menstrual blood and secretions from leaking through an anal bone is provided on an absorbent pad member of the sanitary napkin.

In general, sanitary napkins are for absorbing secretions discharged by women during menstruation, and are divided into an external type, which is closely attached to the outside of the female genitalia, from which the secretions are discharged, and an internal type, which is inserted into the vagina of a woman, depending on the structure.

The external type sanitary napkin has a porous upper sheet for allowing menstrual blood to pass through, an absorbent layer positioned below the upper sheet to absorb menstrual blood flowing through the upper sheet, and a periphery positioned below the absorbent layer to have a periphery of the upper portion It consists of a waterproof sheet attached to the periphery of the sheet.

On the other hand, secretion means normal menstrual blood, and the secretion includes endocrine secretions of the human body such as mucus substances in addition to blood components.

If the entire amount of these secretions is not rapidly absorbed by the sanitary napkin, a problem occurs in that some of the secretions leak to the outside of the sanitary napkin and contaminate underwear or outerwear.

In this case, an unpleasant odor may be emitted by the secretions leaked to the outside of the sanitary napkin, and bacteria multiply in the secretions, which causes sanitary problems.

In order to solve this problem, the "double absorption sanitary napkin" (Patent Document 1) of Korean Patent Publication No. 10-0845246 uses a double absorption structure to maintain the absorption capacity and rewet prevention effect of the existing sanitary napkin and to be applied to the existing sanitary napkin. A sanitary napkin having a significantly faster absorption rate compared to that was proposed.

However, a conventional sanitary napkin including a double absorption sanitary napkin as in Patent Document 1 has a problem in that menstrual blood leaks to the outside along the anal bone when the wearer sits or lies down, and the size of the sanitary napkin varies depending on the amount of menstrual blood. It contains a problem that the user has to endure various inconveniences caused by using various types of sanitary napkins.

As another prior art for solving this problem, the "functional sanitary napkin" of Korean Patent Registration No. 10-1879280 includes a pad body that is adhered to the inner surface of underwear through a first adhesive provided on the lower surface, and an upper surface of the pad body. It is formed in the absorbing part for absorbing menstrual blood, is installed along the longitudinal direction of the pad body on the upper surface of the absorbing part, the menstrual blood is received before the absorbing part, and a guide part for delivering the received menstrual blood to the absorption part. A sanitary napkin was proposed.

However, the sanitary napkin of Patent Document 2 has a possibility that menstrual blood may flow backward through the guide part depending on the posture of the wearer, such as lying face down. Since there is no separate means for fixing the free end of the guide part while inhibiting the fit of the guide part, there is a problem that the guide part easily detaches from the anal bone.
