Abstract

(57) [Summary] [Structure] A pull-out string 3 is attached to the center of a square sheet-like fiber piece 1, a slit 2 is provided in the outer peripheral area of the fiber piece 1, and the fiber piece 1 is shaped like a parachute around the string 3. Shrink it and press-mold it into a rod. [Effect] Since the rod-like body has slits, it has good menstrual blood absorption and can easily swell and expand to sufficiently close the vaginal cavity and prevent menstrual blood leakage.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a sanitary tampon that closes the vaginal cavity and absorbs and retains menstrual blood.

0002

[Issues to be solved by conventional technology and ideas]

Conventionally, in this type of tampon, the central part of the sheet-like fiber piece formed into a square Attach and extend a pull-out string, and pull the sheet-like fiber piece forward around the string A rod-shaped body that is narrowed in the opposite direction to the direction in which the cord extends and has an approximately uniform diameter over its entire length. (For example, Japanese Patent Application Laid-Open No. 49-83292, Jikko 3-982). This tampon is formed so that it swells well When this happens, the tip expands into a parachute shape starting from the rear end where the string is located. This is to enable sufficient reception of menstrual blood. However, this In a tampon, the tip has a higher fiber density and is harder than the rear end. For this reason, the absorption rate is relatively low, and even if it is absorbed, the tip will not swell sufficiently. It does not expand.

0003 On the other hand, in order to eliminate these drawbacks, two sheet-like fiber pieces formed in a rectangular shape were Layer them in a criss-cross pattern, attach a pull-out string to the intersection, and extend the string. Sanitary tampons shaped like tampons are also known. But this It takes more time to manufacture than tampons.

0004 The problem with this invention is that while it has the form of the former tampon, it is an extremely simple method. The object of the present invention is to construct a tampon so that it easily absorbs menstrual blood and swells.

[0005]

[Means to solve the problem]

In order to solve the above problem, this invention is based on a sheet-shaped material formed into a substantially square shape. Attach and extend a drawstring to the center of the fiber piece, and draw the sheet around the string. Physiological fibers made by compressing and compressing a rod-shaped fiber piece in a direction opposite to the extending direction of the string. tampons are required.

[0006] In this invention, on the above premise, the string is attached to the outer peripheral area of the sheet-like fiber piece. A plurality of slits extending radially are provided at the center.

[0007] In a preferred embodiment, the fibers have a higher tear strength than the sheet-like fiber pieces. Exterior fabric pieces that are intertwined or joined to maintain a sheet form are placed at least on the outside of the rod-shaped body. The sheet-like fiber piece is overlapped with the surface of the sheet-like fiber piece, which will become a surface, and pressed to form the rod-shaped body.

[0008]

[Effect]

In the tampon according to this invention having the above structure, menstrual blood flows onto the surface of the rod-shaped body. It is absorbed by the rod-shaped body from the surface, especially each of the slits, and swells. And each of the above The presence of the slit makes it easier for the rod-shaped body to expand from its tip.

【Example】

An example of the tampon according to this invention will be explained with reference to the drawings as follows. It is.

0010 As shown in Figure 1, tampons are simply made of hydrophilic fibers such as cotton and rayon. The constituent material is a square sheet-like fiber piece 1 cut from an accumulated web. S A plurality of slits 2 (see FIG. 6) extend from the outer periphery of the sheet-like fiber piece 1 to the vicinity of its central region. (light) are arranged radially from the center. Center part of sheet-like fiber piece 1 A pull-out string 3 is attached to and extends outward (toward the bottom surface of the fiber piece in the figure).

[0011] As shown in FIGS. 2 and 3, the tampon is shaped like a sheet with the drawstring 3 at the center. The fiber piece 1 is compressed into a rod-shaped body 4 by compressing it in the direction opposite to the extending direction of the drawstring 3. There is. This compression molding can be easily performed using a known tampon manufacturing machine.

0012 The slit 2 in the sheet-like fiber piece 1 shown in FIG. It is provided as follows. Furthermore, as can be understood from the view shown in FIG. 5, the slit 2 is However, the arrangement may be different from that shown in FIG. The slit 2 in the illustrated example is closed. However, it may be completely open in the form of a hole or slot, or the width of the opening may be It may be provided so as to gradually expand from its outer end to its inner end or from its inner end to its outer end. stomach.

[0013] As shown in FIG. 7, on both sides of the sheet-like fiber piece 1, there is a Interior and exterior fabric pieces 5 and 6 that have high tear strength and maintain sheet form by entangling or joining fibers Even if the laminate is stacked, a slit 2 is provided in this laminate, and the rod-shaped body 4 is press-molded. good. In addition, as shown in FIG. 8, slits 2 are not provided in the interior and exterior cloth pieces 5 and 6. You can also do this. Hydrophilic fibers are bonded to the interior and exterior fabric pieces 5 and 6 using a binder. Or, in addition to nonwoven fabrics whose fibers are entangled with high-speed water jets, melt-bonded nonwoven fabrics, spa Bonded nonwoven fabrics can also be used, but nonwoven fabrics made of these hydrophobic fibers are The woven fabric should preferably have good liquid permeability, and to do so, it should have a relatively low fiber density. In addition to making the cloth pieces 5 and 6 wet, a large number of holes are formed in the cloth pieces 5 and 6, or they are treated with a hydrophilic agent. Measures such as these can be taken. In this way, the outer surface of the cloth pieces 5, 6, especially the rod-shaped body 4, If the cloth piece 6 is located at This can prevent this from remaining in the vaginal cavity and causing unsanitary conditions.

[0014] In drawer string 3, it causes capillary action and menstrual blood travels through the string and exits. It is preferable to use monofilament so as not to ooze into the area.

[0015]

[Effect of the idea]

According to the tampon according to this invention, menstrual blood is absorbed into the rod-shaped body through the slit. It swells and spreads easily from its tip, absorbing more menstrual blood and sealing it tightly against the vaginal cavity wall. When worn, it can sufficiently close the vaginal cavity and prevent menstrual blood from leaking.
