BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sanitary article, and more particularly to a sanitary tampon to which an absorbent can be easily inserted.

[0002]

2. Description of the Related Art Currently, two types of tampon are mainly used: a plastic applicator type and a finger type. As shown in FIG. 8, the applicator-type tampon 1 includes an outer cylinder 3 that accommodates the absorber 2 and an inner cylinder 4 that is configured to be insertable into the outer cylinder 3. Are formed, and the pores serve as an introduction path for pulling out the string 5 for taking out the absorber 2 from the inside of the outer cylinder 3 to the end of the inner cylinder 4. The absorber 2 used here is made by compression-molding absorbent fibers into a cylindrical shape.

In order to insert the tampon 1 of the applicator type, as shown in FIG. 9, the outer cylinder 3 of the tampon 1 is gripped by touching the outer cylinder 3 with the thumb and the middle finger, and the index finger is placed on the base end surface of the inner cylinder 4. When the inner cylinder 4 is pushed in with a forefinger after the outer cylinder 3 is inserted and positioned at a predetermined position, the absorber 2 accommodated in the outer cylinder 3 is pushed out of the outer cylinder 3 and inserted into the predetermined part. Thereafter, the outer cylinder 3 and the inner cylinder 4 are taken out to complete the insertion of the absorber 2.

On the other hand, a finger type tampon 1
There is no applicator, and it is composed of the absorbent body 2 and the takeout cord 5 (see FIG. 10), and the absorbent body 2 is directly inserted in use. In any of the above types of tampon 1, it is difficult to insert the tampon 1, and there has been a difficulty in spreading the tampon 1 in general. However, in the past, the plastic applicator type shown in FIG. Tampon 1 has been said to be relatively good.

[0005]

However, in the conventional applicator-type tampon 1, when the absorbent 2 is pushed out of the applicator, the cotton lumps forming the absorbent 2 move while contacting the vaginal wall. When moving through the vaginal tract having a large frictional resistance and a flat cross section, it is difficult to smoothly insert the vaginal passage into a predetermined position because the direction cannot be determined.

Accordingly, an object of the present invention is to eliminate the frictional resistance between the absorber and the vaginal wall, to allow the absorber to be smoothly inserted into a predetermined position in the vagina, and to smoothly remove the accommodating cylinder from the absorber. It is to provide a tampon that can.

[0007]

According to the present invention, there is provided a tampon comprising an absorbent body housed in a housing tube, wherein the housing tube is connected to a flexible tubular sheet portion and the flexible tubular sheet portion. A first extraction tool and a second extraction tool are respectively connected to the distal end of the flexible tubular sheet portion and formed to be longer than the length of the storage cylinder, Further, a first takeoff device and the second takeoff device, are different in length to reach the connecting portion of the tip to each other from a and the point of attachment of the attachment points joined by some other, the Flexible tubular sheet

Are longer than the entire length of the tampon 1. In addition, the first and second takeout cords 63, 6
4 is in a state where the parts respectively drawn out from the inner cylindrical portion 62B are connected, but it is more preferable in operation if this part is formed in a loop shape.

The first extraction string 63 and the second extraction string 64 have a connection point 65 partially connected to each other inside the rigid cylindrical portion 62. Also, the first extraction string 63 and the second extraction string 64
From each connection point 65, the flexible tubular sheet portion 62
The length of the leading end of the flexible tubular sheet portion 61 is different from the leading end of the flexible tubular sheet portion 61 when the first takeout string 63 and the second takeout string 64 are simultaneously pulled up. by pulling with a, it is easier to cleave the opening 61A _3. That is, the first extraction string 63 is formed to have a length that does not have a margin from the connection point 65 to the connection portion of the distal end, but the second extraction string 64 is formed from the connection point 65 to the distal end. The connection portion has a sufficient length to allow the connection portion to be loosened.

The difference between the lengths of the two 63 and 64 is 10 to
It is preferably in the range of 50 mm. If this difference is less than 10 mm, there is no significance in making the lengths of the first extraction string 63 and the second extraction string 64 different.
Beyond mm too slow timing of operation of the second withdrawal string 64, there is a risk that can not be promoted cleavage of the opening 61A _3.

The flexible sheet used for the flexible tubular sheet portion 61 only needs to have a flexibility that can follow the movement of the drawer string 63. Examples of the material of the conductive sheet include synthetic resins such as polytetrafluoroethylene, polyethylene, polypropylene, polyethylene terephthalate, and nylon.
Flexible sheet made of polytetrafluoroethylene with a thickness of 60
When molded to a thickness of μm, the flexible sheet has the following physical properties.

The tensile strength in the MD direction (longitudinal direction) of the film is 1200 g / mm ² , and the stretching ratio is 200%. The tensile strength in the TD direction (lateral direction) of the film is 100%.
g / mm ² , stretching ratio is 800% When the flexible tubular sheet portion 61 is formed using the above-mentioned sheet, a portion which is not desired to be stretched and deformed is held down, and a portion which is desired to be stretched and deformed is freed and stretched. By doing so, one direction is stretched and the other direction is contracted to form the intended flexible tubular sheet portion.

On the other hand, when the rigid cylindrical portion 62 is inserted,
Any material may be used as long as it does not substantially deform and transmits the pressing force to the absorber 2, and such a material is preferably formed of the same synthetic resin as in the case of the flexible sheet. It may be paper having strength. Next, the usage of the tampon 1 of this embodiment will be described.

First, the inner cylindrical portion 62B of the tampon 1 shown in FIG.
The grooves 62B ₁ is fitted in the protrusion 62A ₂ of the outer tube portion 62A of the engaged state of pulling out the inner tubular portion 62B with (see Fig. 2). Next, the distal end of the flexible tubular sheet portion 61 that accommodates the absorber 2 is applied to a predetermined portion, and the protrusions 62 of the inner tubular portion 62B
Push to B _2, projections of the inner cylindrical portion 62B of the tampon 1 6
Locked to at 2B _2. When the first and second takeout cords 63 and 64 are simultaneously pulled up in this state, first, the first takeout cord 63 is tensioned and pulled up to the distal end of the flexible tubular sheet portion 61. 2 take-out strings 64
Remains loose, the lifting load is
Acts to concentrate on the second withdrawal string 64 is connected one part through the perforations 6 to reach the opening 61A ₃
Openings 61A ₃ promotes to cleave at 6. Further, when the pull-out strings 63 and 64 are pulled up, the perforations are further torn with the pull-up of the first pull-out string 63, and half of the flexible tubular sheet portion 61 is gradually pulled up.
Next, the second take-out cord 64 starts to be tensioned, and the remaining portion of the flexible tubular sheet portion 61 is gradually pulled up so that the flexible tubular sheet portion 61 smoothly moves from the absorber 2 as shown in FIG. Stripped off. Furthermore, when pulling up the extraction string 63, a flexible tubular sheet 61 is the absorbent body 2 completely peeled off from the absorbent body 2 is positioned in the projection 62B ₂ of the inner cylindrical portion 62B are exposed in the vagina predetermined (See FIG. 4). Thereafter, when the inner cylinder portion 62B is gripped and pulled out, the string 5 of the absorber 2 comes out of the accommodation tube 6 and
Is inserted.

Therefore, according to the tampon 1 of this embodiment,
The insertion position of the absorber 2 in the vagina is determined by the position where the applicator is inserted, and after insertion into the vagina, there is no need to move the absorber 2 further, and the direction of the absorber 2 changes in the vagina. Without absorbing, the absorber 2 can be positioned at an arbitrary position from the outside when the applicator is inserted, and can be smoothly inserted. At this time, since the first extraction string 63 and the second extraction string 64 pull up the distal end portion of the flexible tubular sheet portion 61 with a time lag, the tearing at the perforation effectively acts to open the opening 61A. It can be split smoothly.

FIG. 5 shows a tampon 1 according to another embodiment of the present invention. As shown in FIG. 5, the tampon 1 of the present embodiment includes the tampon 1 of the above embodiment and a rigid cylindrical portion 62.
