Description

Absorbent article for attachment of auxiliary pad {ABSORBABLE ARTICLE FOR MOUNTING AUXILIARY PAD}

The present invention relates to an absorbent article for attaching an auxiliary pad capable of attaching the auxiliary pad detachably.

Conventionally, sheet-like absorbent articles containing an absorbent body have been widely used as feminine hygiene articles for absorbing body fluids. Among such sheet-like absorbent articles, many efforts have been made to prevent leakage of menstrual blood, especially for high demand sanitary napkins.

As a sanitary napkin having a high effect of preventing the leakage of menstrual blood, for example, a raised portion is formed in a part in contact with the vicinity of the wearer's labia in Japanese Unexamined Patent Application Publication No. 58-191020 or Japanese Unexamined Patent Application Publication No. 58-43430, The improvement of the adhesiveness of a sanitary napkin with respect to the labia which has is disclosed.

Further, Japanese Patent Laid-Open No. 10-504486 discloses bonding a cylindrical or cylindrical absorbent layer in the transverse direction on the skin contact surface side, making the absorbent layer easy to conform to the wearer's operation, and fitting to the wearer's labia. Sanitary napkins have been proposed.

However, since the discharge of acupuncture points is not constant and fluctuates throughout the menstrual period, there is a problem in the conventional example as described above that only the foreigner feels unnecessarily at the time when the discharge of the acupuncture points is low.

On the other hand, a so-called ultra-thin sanitary napkin having a thickness dimension of 1 to 4 mm can provide a comfortable fit, but since the fit of the labia is low, when the discharge of the acupuncture points is large, anxiety is caused to the leakage of the acupuncture points.

As described above, the conventional sanitary napkin is only suitable for the case where the amount of menstrual blood is large or small, and it is not possible to cover the entire menstrual period flexibly in response to the change in menstrual blood emissions.

In this regard, Japanese Patent Laid-Open No. 10-127692 proposes a rod-shaped auxiliary absorber to be used in combination with a sanitary napkin. This auxiliary absorber fills the space between the grooves of the buttocks and the sanitary napkin to increase the prevention of leakage of menstrual blood, and can be used supplementally when the amount of menstrual blood is high. For this reason, the wearer is freed from the trouble of selecting a suitable sanitary napkin.

However, it is cumbersome to attach it to the buttocks to which the acupuncture points are attached, and in particular, when the auxiliary absorber is fixed to the sanitary napkin with an adhesive, it is difficult to grasp the exact fixing position to the sanitary napkin, so it is fixed at the correct position. There is also a fear that the pitability is lowered and the leakage preventing effect cannot be sufficiently exhibited.

This invention is made | formed in view of the above subjects, and the objective is to provide the feminine hygiene article which can handle through the whole menstrual period, and is easy to handle.

In order to solve the above problems, in the present invention, an auxiliary pad that complements functions such as body fluid absorbing ability of the absorbent article can be freely attached to and removed from the absorbent article, and the attachment position thereof is applied when the auxiliary pad is attached. A guide element for guiding is provided to an absorbent article.

More specifically, the present invention provides the following.

(1) An absorbent article for attaching an auxiliary pad for assisting the absorbent article such as body fluid absorption ability, the guide for guiding the attachment position of the auxiliary pad to the body side facing the wearer's body side when worn by the wearer; An absorbent article for attaching an auxiliary pad, comprising an element.

According to such an absorbent article for attachment to an auxiliary pad according to the present invention, an auxiliary pad that complements a function such as absorption of body fluid (especially acupuncture points) can be detached and a guide element for guiding the attachment position of the auxiliary pad to the body side is provided. Formed. For this reason, the wearer can select whether or not to attach the auxiliary pad to the absorbent article for attaching the auxiliary pad, and, when selecting to attach the auxiliary pad, can adhesively fix the auxiliary pad to an appropriate position based on the guide element.

Here, menstruation is continued for about a week, but as described above, a certain amount of menstrual blood is not always discharged. Specifically, until the third day from the start of menstruation, the amount of acupuncture points is high and about 70% of acupuncture points are discharged, but after that, about 30% of the points are released.

As such, the amount of menstrual blood changes, so that the optimal sanitary napkin is inevitably changed for the wearer. However, it is very cumbersome and psychological burden for the wearer to properly select and purchase such sanitary napkins and to use them separately.

In this regard, the present invention is to be attached to the auxiliary pad in accordance with the guide element formed on the body side of the absorbent article for attaching the auxiliary pad in the period of high discharge of acupuncture points, and for the auxiliary pad attachment without attaching the auxiliary pad in other periods. What is necessary is just to use an absorbent article as it is. In addition, by making the absorbent article for attaching the auxiliary pad a thin type having a thickness dimension of 1 to 4 mm, a feeling of wearing suitable for a period of low discharge of menstrual blood can be obtained.

 As described above, according to the present invention, it is possible to flexibly respond to the request of the wearer to be changed according to the change of the menstrual blood discharge, and the wearer can purchase various hygiene products in advance in order to be able to cope with the somewhat of the discharge. It is freed from the hassle of using it separately so that a suitable hygiene product can be used easily.
