Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a sanitary napkin that has various functions in one sheet, and the napkin is manufactured using an absorbent layer made of absorbent paper such as a sheet polymer, as shown in Figure 9. A flat absorbent material is obtained by making (α) into a flat shape, layering waterproof paper Th) on one side, and then covering the whole with a covering material (C)′ such as a non-woven fabric.
Divide into approximately 3 equal parts in the width direction, fold both end pieces (3) (3) toward the waterproof paper side from the fold line (3') (3G, and then divide these end pieces (3) (3) into two, respectively. Piece (3α) (
3α) is folded back and polymerized, and both edges in the longitudinal direction are fused (4) + 4) Attach a part of the bottom side of 1515 (approximately 1/3 of the total length) death.

A bulge (2) having a valley groove (1) (1) is formed on both sides at the center groove (1) of the center button, and a free end piece (3α) (3α
) Attach double-sided adhesive tape (s) f5) to the bottom of (6)
It is characterized by being configured as follows.

The present application has the above-mentioned characteristics. 9 Usually, the central line (
1) and the left and right folds f33 (35) are combined to reduce the 8 sides into a rod-shaped body and make it into a mobile phone side, and when using it, fold the side ends of both free end pieces (3cL) (3a) on both sides. If you stretch it out, you can expand it while keeping both longitudinal ends glued and fixed.

The protruding stripes (2) on the part where the bottom is attached protrude and are held, and the protruding stripes that adhere to the local area and the absorbent layer covering them are formed in three stages, increasing the absorption area and stretching to both sides. The width can be adjusted as desired depending on the scene.

In other words, the pyramid-shaped bulge formed at about one-third of the longitudinal direction does not deform and maintains the same shape with a large absorption area as before use, and the pleats remain on both sides (ill).
It is contracted to form an X-shaped swollen shape, and it fits perfectly to the private area during menstruation and completely seals it, so there is no slippage or leakage, and the adhesion part can be adjusted to bulges, folds, and other areas. It is formed in three tiers of the mount, providing a large absorption capacity for a long time at the required location. The shape with three levels of absorbent areas is not compact and has an absorbent layer twice the size of current sanitary napkins of the same size.

Furthermore, since it is made in a shape that is closest to the shape in use, there is no reduction in absorption area during use. Then, due to narrowing from the left and right in the longitudinal direction, wrinkles are formed in the center.
The shortcomings of conventional napkins, such as a significant reduction in absorbent area, are solved. If you use it as is without stretching it, you can use it as a mini, and by fixing the double-sided tape to your underwear depending on the degree of expansion, you can also use it as a regular size or night size. , it does not fit a napkin and also has the function of a tampon.

Book 11 as above! According to riK, the central bulge is made from the beginning in a shape that is closest to the shape when in use, and 9 width sizes can be freely selected, so the absorption capacity is extremely large, and it can be used according to the situation without slipping or leaking. It has an extremely wide range of effects.

Claims (1)

[Claims] (1) A flat absorbent material made of an absorbent layer covered with a nonwoven fabric is divided into thirds in the horizontal direction, both end pieces are folded inward, and the both end pieces are further folded.
After polymerizing the free end pieces that were divided into two halves and folded back outward, and fusing both longitudinal edges including the folded overlapping part,
□ A method for manufacturing a sanitary napkin, characterized in that the central part is bulged out, the back parts of the napkins are pasted together, and a double-sided adhesive tape is provided on the bottom of the free end pieces. 2. Both end pieces of the flat absorbent form were divided into thirds in the horizontal direction, and then the longitudinal edges of the overlapping part were fused and fixed to form a bulge in the center with the back surface pasted.・
