本発明は、経血液の吸収速度を高め、膣内から

る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a tampon that has been improved to increase the absorption rate of menstrual blood and reduce the resistance to withdrawal from the vagina, thereby making the tampon smooth and easy to operate.

産する上で能率的とはいえない。 Conventionally, in order to increase the absorption speed, the fiber fleece that is the constituent material of the tampon body is shifted at the front and rear ends of the tampon body, so that the density of the front and rear ends of the tampon body is lower than that of the center, or the front and rear ends of the tampon body are Tampons are known in which a material having a higher absorption rate is placed in the central part of the tampon than in the central part. However, doing so cannot be said to be efficient in mass-producing tampons at high speed.

る。 Conventionally, in order to reduce the resistance to removal of the tampon body from the vagina due to the tampon body expanding uniformly over almost the entire body when absorbing menstrual blood,
Tampons are known in which a means for preventing expansion, such as a cap, is attached to the outer surface of the rear end of the tampon body. However, doing so is not only inefficient as described above, but also fails to fully achieve the intended purpose. Conventional tampons, including this tampon, are formed by compressing the tampon body substantially only in its axial direction, so that it expands only in its axial direction when absorbing menstrual blood. In particular, tampons in which the tampon body is compressed only in the axial direction and are formed with compression grooves in the axial direction on the outer circumferential surface have a higher absorption of menstrual blood than other known tampons that do not have such grooves. The tampon has very good expandability in the diametrical direction, and therefore its performance as a tampon is outstanding, but on the other hand, the withdrawal resistance is extremely high. Therefore, such tampons may cause abrasions on the vaginal walls due to friction when they are removed from the vagina.
The withdrawal cord may even pull out or break from the tampon body, leaving the tampon in the vagina.
本発明の目的は、上述のような欠点を改良する

図示の実施態様に基づいて説明すると、以下の通
りである。 The purpose of the present invention is to obtain a method for manufacturing a tampon that can improve the above-mentioned drawbacks, and the configuration of the present invention for achieving the purpose will be explained based on the illustrated embodiment. , as follows.

成し得るものであればすべて使用可能である。 FIG. 1 shows a fleece 1 constituting the tampon body of the present invention. Fleece 1 is made of water-absorbent fibers such as cotton and rayon, which are commonly used in tampons, and is simply a layered collection of fibers without using fiber binding means, and a non-woven fabric made of water-absorbent or water-absorbent fibers. Any material that can be formed into a fleece shape can be used, such as a layered material or a single water-absorbing fiber nonwoven fabric.

It is formed by hanging the pull-out cord 3 on the fleece 1 at right angles as shown in the figure, and folding the fleece 1 from one end thereof or in half and winding the fleece 1 in a spiral shape as shown in FIG. 2 using the fold as a starting point.

の直径方向にも僅かに圧搾する。 In FIG. 3, the steps of compression molding the cylindrical body 2 are shown in the order of A, B, and C. Reference numeral 4 denotes a pressing body, which has a smaller diameter than the diameter of the cylindrical body 2, and is arranged so as to move forward and backward in opposition to each other. A cylindrical body 2 having a length l 1 and a diameter d 1 is positioned between both pressing bodies 4, and both pressing bodies 4 are advanced in mutually opposing directions so that the center of both end faces of the cylindrical body 2 is After compressing the part by pressing it in the axial direction so that a concave part 5 is formed in that part, and retracting both pressing rods 4, the part is shaped into a diameter d 2 using a molding machine (not shown). A columnar tampon body 6 is formed by squeezing in the diametrical direction. In this case, in order to make the tip of the main body 6 round, it is also compressed slightly in the diametrical direction as necessary.

なる。 FIG. 4 shows another method for molding the cylindrical body 2, and in this case, the steps are shown in the order A, B, C as before. Reference numeral 7 denotes a pressing body, which has a pressing protrusion 9 projecting from the center of a pressing surface 8 having a diameter equal to or larger than the diameter of the cylindrical body 2. They are arranged so that they move forward and backward facing each other. The length between these two pressing bodies 7
l 1 and a diameter d 1 is positioned, both pressing bodies 7 are advanced in mutually opposing directions, and these pressing protrusions 9 are used to press the center portions of both end faces of the cylindrical body 2 into that area. While pressing and squeezing in the axial direction so that the concave portion 10 is formed, both pressing surfaces 8
After pressing and squeezing the entire body in the same direction so that it has a length l 2 and moving back both pressing bodies 7, it is squeezed using a molding machine (not shown) to have a diameter d 2 and form a columnar shape. A tampon body 11 is formed. In this case, unlike the forming method shown in FIG. 3, the entire cylindrical body 2 is also compressed in its axial direction, so the length of the cylindrical body 2 before compression is equal to the length of the tampon body after compression. A length longer than 11 will be used.

ましくは斯く残るように圧搾する。 At both ends of the main bodies 6, 11 molded by the molding method shown in FIGS. 3 and 4, the concave portions 5, 10 are crushed and reduced in size due to the extent of compression in the diametrical direction, parts 5a, 10b. It is preferable to squeeze so that it remains.
第５図には、前記本体６，１１の外周面の軸線

る。 As mentioned above, in the tampon bodies 6, 11 obtained by the manufacturing method of the present invention, the bodies 6, 1
Since the density of the front and rear end portions of 1 is lower than that of the center portion, the absorption rate of transmensional blood is increased, and the resistance to removal from the vagina is reduced. In addition, in the case of the main body 11, the length of the drop-wound cylindrical body 2 before compression is made longer than the length of the main body 11, and since it is also compressed in the axial direction, it also expands in the axial direction, so that the diameter The expansion force in the direction will be inferior to that of known tampons, but the tampon will expand in the axial direction to the extent that the expansion force in the diametrical direction is reduced. Therefore, while maintaining expandability in the diametrical direction, the expanded diameter does not become larger than necessary, which, together with the effect of the low density, further reduces the resistance to withdrawal from the vagina. has functions equivalent to or better than known tampons.
