Abstract

PROBLEM TO BE SOLVED: To eliminate the spillage of mensual blood and urine from a human body without being absorbed, the shortcoming of the conventional napkins because a groove to a hip part from a discharge part thereof fails to tightly fit the napkin, eventually causing a clearance between the napkin and the part of the human body contacting the napkin to let the mensual blood and urine spill through a groove splitting the hip part and the front part. SOLUTION: In the shape of the solid napkin, a portion thereof is raised in a mound from one end to the other end thereof along the longitudinal center line and curved from the center to both ends thereof and also curved along the length thereof in a longitudinally vertical cross section. This allows the duplication of the shape of a part of the body contacting the napkin. If provided at the center of the napkin, a gather causes a part with the gather to shrink uneven. By the utilization of this method, a solid napkin is produced with a groove and a curve from the vagina part to the hip part which are worked to duplicate the shape of the part of the body contacting the napkin.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to napkins in which a longitudinal center line has a mountain shape and both longitudinal ends are curved.

[0002]

2. Description of the Related Art Conventionally, commercially available napkins have a flat shape or have only a gentle curve. In addition, as in the sanitary napkin sandwiched between the buttocks of the Japanese Utility Model Application No. 5-29328 filed for utility model registration, only a portion from the center to the rear in the longitudinal direction is convex, and Even if there is no longitudinal curvature, or even if there is a longitudinal curvature like the sanitary napkin of the application No. 4-340001, a flat thing without a mountain-shaped raised portion on the center line is devised. Has been
In any case, these napkins differed greatly in the shape of the body part to which they were applied.

[0003]

In the prior art, since the groove from the excretion part of menstrual blood and urine to the buttocks is not in close contact with the napkins, a gap is formed between the napkins and the body part to which it is applied. This has the disadvantage that menstrual blood and urine that have flowed into the buttocks and the front cracks leak without being absorbed by the napkins, and contaminate the underwear. The present invention has been made to eliminate this disadvantage.

[0004]

According to the present invention, a ridge is formed in a mountain shape from end to end along a longitudinal center line, and a cross section perpendicular to the longitudinal direction has a curved shape from the center to both ends, and further curved in the longitudinal direction. As a result, the napkins are characterized in that they have a shape that duplicates the shape of the body to which the napkins are applied. Along the longitudinal centerline,
By making gathers, napkins are made to protrude into a mountain shape and have a cross section perpendicular to the longitudinal direction that has a curved shape from the center to both ends and that is also curved in the longitudinal direction. . The term "napkins" as used herein refers to articles intended to absorb liquids that come out of the vagina and the urethra, such as sanitary napkins, diapers, and urine collecting pads. Here, the shape of a napkin is a duplicate of the shape of the body, and the shape-replicating type is a shape similar to the part to be worn, as if the shape of the napkin was duplicated. Refers to the state in which

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Napkins according to the present invention will be described in more detail with reference to FIGS. (A) Method of making with a mold. Take a mold of the body where the napkins are to be attached with clay or the like, and press the napkins according to the mold. (B) How to put center gathers. Since the method (a) is costly, as shown in FIG. 1, when a center gather is placed along a longitudinal center line in a flat napkin, the relevant portion rises and extends from the center line to the left and right ends. Both the face and longitudinal ends, ie, the front and rear, are curved. In addition, if you put the gathers on the side of the buttocks, that is, the gathers at the back, tightly, the entire back will bend upwards, so the napkins will be curved like a peach crack that fits perfectly with the body curve from near the vagina to the buttocks. You can have it. (C) A drafting method. As shown in FIG. 6, napkins are divided into a left half and a right half by drafting, superimposed on the outer surface, and the center side is sewn along the seam in the figure, and then the two unsewn sides are sewn. Spread the edges left and right.
Also, instead of stitching, similar parts can be made by pasting overlapping parts together. However, the stitching method has a more convex central portion, so that when a napkin is worn, it can be fitted into the groove at the central portion of the body. (D) Stitching together gathered pieces. FIG.
As shown in the figure, if one of the longer sides of the rectangle is gathered, it can bend. Two of them are prepared, and as described in (c) above, they are made by overlapping the outer surface and sewing the gathered side together.

[0006]

According to the present invention, the napkins are formed by bending the body so as to follow the curve of the body from the urine or menstrual blood discharge port to the buttocks, and by making the center of the vagina or the buttocks into a mountain shape so as to fill the grooves. The effect of preventing leakage of urine and menstrual blood is enhanced. Also, when gathers are placed on a flat object, elasticity is created. Therefore, when the body presses the napkins while wearing the napkins, the recoil thereof strengthens the curvature of the front part and the rear part, and further adheres to the body. Further, since the portion shrunk by the gathers is compressed, the density of the absorber inside the napkin increases, and the absorbing power can be increased.
