DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a sanitary napkin in an individual bag.

[0002]

2. Description of the Related Art Japanese Utility Model Laid-Open No. Hei 7-21018 discloses a sanitary napkin in an individual bag. This individual bag,
It is formed by bending an elongated plastic film into three layers so that both ends in the longitudinal direction overlap, and welding the overlapping films at both side edges of the bag.
When removing the napkin, the film may be torn along the welded portion. The napkin has an adhesive area formed on its back surface, and a release sheet that covers and protects the adhesive area,
One end thereof is fixed to the inner surface of the film. When the napkin is removed, the release paper automatically peels off and remains on the film side.

[0003]

When the napkin is taken out of the known sanitary napkin containing individual bags, the individual bags are torn at both side edges to open a large mouth. This individual bag makes it easy to take out the napkin, but it is difficult to put the napkin back in the open individual bag. For example, when the user wants to close the napkin again without using it, he cannot use the original bag. If you do not store the napkin in a separate bag,
It can be unsanitary. However, in the case of individual bags in which the release paper is automatically peeled when the napkin is removed, it is generally essential to break the individual bags, and so far, such individual bags have been used again. There is no effective technology to do that.

[0004] Therefore, an object of the present invention is to make it possible to reuse an opened individual bag in a sanitary napkin containing individual bags.

[0005]

In order to solve the above-mentioned problems, the present invention is based on the premise that a sanitary napkin folded in the front and rear longitudinal direction and an individual bag in which the napkin is enclosed. The napkin is covered and protected by a release paper on an adhesive area for fastening the shorts formed on the back surface of the napkin, and the individual bag is formed by an upper sheet portion and a lower sheet portion sandwiching the napkin. This is a sanitary napkin in an individual bag having a quadrangular shape having two sets of two parallel sides.

On this assumption, the present invention is characterized in that one of the two sets of parallel sides of the individual bag is provided.
A pair is parallel to both longitudinal edges of the napkin, another pair is parallel to both width edges of the napkin, and a top sheet portion of the individual bag has two sides parallel to the both edges. Starting from one side and extending toward the other side, two relatively easy tearable opening portions are formed parallel to each other with a separation dimension smaller than the width of the napkin, and the napkin is formed on a back surface of the napkin. And one end in the longitudinal direction of the napkin is arranged near one side of the individual bag where the unsealing portion starts, with the inner surface of the upper sheet portion of the individual bag facing each other, and covers the back surface of the one end. Release paper is bonded to the inner surface of the upper sheet portion between the two opening portions.

Are integrated in the welding wire 10 so as not to be present.

The width direction of the front edge 6 is divided into a central region 6A and left and right side regions 6B. In the central region 6A, the upper and lower sheet portions 4 and 5 are in a non-joined state, and in the side region 6B. The two sheet portions 4 and 5 are united by a welding wire 10 so that the mouth is not substantially opened. When the width of the napkin 2 is 30 mm or more, the width of the central region 6A is 20 mm.
That is, the width is set to not more than ３ of the width of the napkin 2. The central area 6 </ b> A is a holding portion for opening the individual bag 1 with respect to the upper sheet portion 4, preferably a holding portion where a finger can be inserted between the upper and lower sheet portions 4 and 5.

When the upper sheet portion 4 is gripped in the central area 6A and pulled upward as indicated by the arrow P, the upper sheet 4 is torn at both perforations 11 and the individual bag 1 is opened. However, both perforations 11 end shortly before the rear edge 7, and the top sheet 4 tears and stops until the perforation 11 ends.

FIG. 2 is a sectional view taken along the line II-II in FIG.
The napkin 2 is shown in a side view. The napkin 2 is bent in three layers in the longitudinal direction such that the front and rear ends overlap with the skin contact surface inside. An adhesive 12 for fastening the napkin 2 to shorts (sanitary panties) for wearing the napkin 2 is applied to a non-contact surface with respect to the skin which is bent to the outside. The adhesive 12 is covered and protected by a release paper 13, and the release paper 13 is attached via a hot-melt adhesive 15 so that one end does not peel off to the inner surface of the upper sheet portion 4 of the individual bag 1. (See also FIG. 1). Although the width of the release paper 13 can be smaller than the distance between the two perforations 11, it is preferable that the width is slightly larger than the distance as shown in FIG. Are perforated 11 and individual bag side edge 8 or 9
Is adjusted so as to be located below the upper sheet side edge portion 4A.

In the sanitary napkin with the individual bag thus constructed, one hand holds the vicinity of the central area 6A of the individual bag 1,
With the other hand, the upper surface sheet portion 4 of the central area 6A is gripped and pulled in the direction of arrow P, and when opened, the release paper 13 moves together with the upper surface sheet 4 and starts to peel off from the napkin 2. Next, while holding the top sheet 4 and holding the one hand, the end 2A of the napkin 2 looking into the central area 6A is pulled in the direction of arrow Q toward the outside of the individual bag 1, and the napkin 2 is taken out. be able to.
