Description

[Detailed Description of the Invention] The present invention relates to a product for treating body fluids such as menstrual blood and urine, and particularly to a thin menstrual blood treatment product.

Recently, menstrual blood processing products (hereinafter referred to as napkins) have been becoming thinner due to the development of menstrual blood absorbing materials and changes in user preferences.

Thin napkins are extremely useful because they are not bulky when handled and used, but if they become thinner than a certain point, they become so-called weak at the waist, and when used, they twist and become narrow, making it impossible to cover the required area of the female private parts. The disadvantage is that menstrual blood leaks.

As a means to eliminate such defects, it is possible to apply an adhesive in a continuous film over a wide area of the non-menstrual blood absorbing surface of the napkin, and to fix the napkin to the shorts through this adhesive. Although such napkins are currently in practical use, applying adhesive in this way not only stains the shorts, but also damages or breaks the shorts due to the adhesive force of the adhesive when the napkin is peeled off from the shorts. , there is a drawback.

The purpose of the present invention is to provide a novel body fluid treatment article that can eliminate the above-mentioned drawbacks, and the structure for achieving this purpose will be explained based on the illustrated embodiment. , as follows.

The drawings show a napkin as an example of the body fluid treatment article of the present invention, and FIGS. 1 and 2 are external perspective views of each embodiment thereof, and FIG. 3 is a diagram of the napkin shown in FIGS. 1 and 2. FIG. 3 is an enlarged cross-sectional view along the width direction.

As shown in FIG. 3, the embodiment shown in FIG. 5. A laminate 7 is formed by overlaying the nonwoven fabric 6 on the lower surface of the laminate 7, and the laminate 7 is thermocompression bonded (welded) so that vertical grooves 8a and 9a are formed slightly inside both long sides of the laminate 7. The laminated state is integrated.

In the embodiment shown in the second figure, the vertical grooves 8a, ga are also provided on both short sides.
It has the same structure as the embodiment shown in the first figure, except that it is thermocompressed so that horizontal grooves 8b and 9b, which have the same shape and are continuous with them, are formed.

The absorbent material 2 is made of water-absorbing paper (paper cotton), compressed or uncompressed pulverized pulp (flottous pulp), water-absorbing polymer alone or in combination, and may be a fibrous web or a water-permeable sheet. 3 preferably consists of 50 to 100% hydrophobic fibers, the waterproof sheet 5 consists of a size-treated pipe sheet or film, and the nonwoven fabric 4
, 6 preferably consists of 50 to 100% hydrophobic fibers.

In the present invention, the positions of the waterproof sheet 5 and the nonwoven fabric 6 are reversed so that the waterproof sheet 5 is on the bottom surface, and the fibrous web or water permeable sheet 3 and the nonwoven fabric 6 are , one or both of these may not be placed.

Moreover, the apparent thickness of the napkin 1 is 2 to 6 mm.

Furthermore, the napkin 1 shown in FIG. 1 is obtained by pressing the laminated body 7, which is shaped into a wide width, with heated rolls or plates having a carved pattern corresponding to the uneven pattern shown in FIG. By cutting along the chain line 10 at the same time, a large amount can be obtained at the same time.

Incidentally, the napkin 1 shown in the second figure can also be obtained in large quantities at the same time by pressing a certain shape with a heated roll or plate having a carved pattern corresponding to the uneven pattern and cutting it.

The body fluid treatment article of the present invention is constructed by thermo-compression bonding and integrating the laminate so that vertical grooves are formed near both long sides of the laminate as described above. Even if it is extremely thin and so-called weak,
Since the longitudinal grooves are hardened by thermocompression bonding, their waist is reinforced, and therefore they are less likely to twist and become narrow during use.

Also, although the vertical grooves are hardened, they are more concave than the surface, and are located inside the long sides of the napkin, so they are difficult to reach into women's private parts. Does not give a foreign body feeling.

In addition, due to the thermocompression bonding of the longitudinal grooves, each layer and fiber in that area are tightly adhered to each other, and the capillary action of the fibers is significantly reduced, so body fluids absorbed by the absorbent body permeate toward the long sides of the napkin. Even if it diffuses, it is difficult to leak outside beyond the thermocompression bonded part.

Furthermore, since the body fluid treatment article of the present invention has a structure in which each member is simply laminated and thermocompressed, it can be manufactured in large quantities at the same time by the means described in connection with FIG. 4 and supplied at a low cost. It is extremely beneficial.
