Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tampon in which an absorber can be easily attached and a method for manufacturing the tampon.

[0002]

2. Description of the Related Art Currently, there are two types of tampons which are mainly used, a plastic applicator type and a finger type.

As shown in FIG. 6, the applicator-type tampon comprises an outer cylinder 3 for accommodating the absorber 2 and an inner cylinder 4 which is insertable into the outer cylinder 3. Four
A pore is formed along the axis of the absorber, and this pore is the absorber 2
This is a path for pulling out the take-out cord 5 from the outer cylinder 3 to the base end of the inner cylinder 4. In addition, the absorber 2 used here
Is an absorbent fiber compressed into a cylindrical shape.

In order to insert the applicator type tampon 1, as shown in FIG. 7, the thumb and the middle finger are put on the outer cylinder 3 of the tampon 1 and held, and the index finger is inserted into the inner cylinder 4.
When the inner cylinder 4 is pushed in with the index finger after the outer cylinder 3 is inserted and positioned at a predetermined position by applying the outer cylinder 3 to the base end surface of the outer cylinder 3, the absorber 2 accommodated in the outer cylinder 3 is pushed out from the outer cylinder 3 to a predetermined position. It is inserted. Then, the outer cylinder 3 and the inner cylinder 4 are taken out to complete the insertion of the absorber 2.

On the other hand, the finger type tampon 1 is
There is no applicator, it is composed of the absorbent body 2 and the take-out string 5 (see FIG. 8), and the absorbent body 2 is directly inserted and attached at the time of use. However, any of the above-mentioned types of tampon 1 has a difficulty in being generally spread because it is difficult to insert the tampon 1. However, in terms of insertion, the plastic applicator type shown in FIG. Tampon 1 has been said to be relatively good.

[0006]

However, since the conventional applicator-type tampon 1 is made of plastic, its wall thickness must be 0.7 mm or more.
In addition, since a clearance of 0.3 mm or more is required to reduce the extrusion resistance when the absorbent body 2 is extruded, the outer diameter of the tampon 1 should be the outer diameter of the absorbent body 2 plus 2 mm or more. I had no choice.

Therefore, the most important issue of performance generally required for a tampon is ease of insertion. That is, the smaller the outer diameter of the tampon, the better, and how to make the outer diameter smaller has been a major issue.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a tampon and a method for manufacturing the tampon which can be easily and comfortably inserted by reducing the outer diameter as much as possible to reduce the resistance at the time of insertion.

[0009]

SUMMARY OF THE INVENTION The present invention comprises a tubular film accommodating an absorber, an outer tube connected to the tubular film, and an inner tube configured to be insertable into the outer tube. Prepare,
A tampon in which a pore is formed in the inner cylinder along the axis, and this pore serves as a path for pulling out the absorbent withdrawal string from the inside of the outer cylinder to the base end of the inner cylinder. The above object is achieved by providing a tampon characterized by having an opening in which an absorber is separably integrated with the opening.

Further, according to the present invention, as a method for manufacturing the above-mentioned tampon, after passing the take-out string of the absorber through the inner cylinder, the absorber is press-fitted into the opening at the tip of the inner cylinder to integrate them into one body. The inner cylinder and the absorber thus formed are inserted into the tubular film and the outer cylinder, and thereafter, the tubular film is heated to shrink, and the tubular film is brought into close contact with the absorber and the outer cylinder. The present invention also provides a method for manufacturing a tampon.

As another method of manufacturing the tampon described above, after inserting the inner cylinder into the tubular film and the outer cylinder, the take-out string of the absorber is passed through the inner cylinder so that the absorber is placed in the opening at the tip of the inner cylinder. Provided is a method for producing a tampon, which comprises press-fitting and integrating both of them, and then heating and shrinking the tubular film to bring the tubular film into close contact with the absorber and the outer cylinder. ..

[0012]

According to the tampon of the present invention, since the absorber is housed in the tubular film connected to the outer cylinder, the outer diameter of the whole is reduced to facilitate the insertion, and the inner cylinder is pushed in after the insertion. This allows the absorber to be pushed out of the tubular film and inserted into a predetermined portion.

Further, according to the tampon manufacturing method of the present invention, after the take-out string of the absorber is passed through the inner cylinder, the absorber is press-fitted into the opening at the tip of the inner cylinder to be integrated. When the tube and the absorber are inserted into the tubular film and the outer tube, and then the tube film is heated and contracted, the tubular film is brought into close contact with the absorber and the outer tube to be integrated.

Further, according to another manufacturing method of the present invention, the inner cylinder is inserted into the tubular film and the outer cylinder, and after the take-out string of the absorber is passed through the inner cylinder, the absorber is attached to the tip of the inner cylinder. When the tubular film is pressed into the opening and integrated, and then the tubular film is heated and contracted, the tubular film is brought into close contact with the absorber and the outer tube to be integrated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the embodiments shown in FIGS. In each figure, FIG. 1 is a cross-sectional view showing a state before use of the tampon according to one embodiment of the present invention, and FIG. 2 is a cross-sectional view showing a state in which the absorber is pushed out when the tampon shown in FIG. 1 is used. 3 is a view showing a tampon of another embodiment of the present invention, which is equivalent to FIG. 1, FIG. 4 is a sectional view showing a usable state of the tampon shown in FIG. 3, and FIG. 5 is a view of the tampon shown in FIG. is there.

As shown in FIGS. 1 and 2, the tampon 1 of this embodiment has a tubular film 6 accommodating the absorber 2, an outer tube 3 connected to the tubular film 6, and an outer tube 3. And an inner cylinder 4 configured to be insertable therein. Then, the inner cylinder 4 is formed with pores 4A along the axis, and the pores 4A serve as a path for drawing out the withdrawal string 5 of the absorber 2 from the inside of the outer cylinder 3 to the base end of the inner cylinder 4. There is.

Further, the outer cylinder 3 forms a grip portion having a strength not to be compressed and deformed by the grip when the tampon 1 is used. Further, the tubular film 6 has its tip slightly reduced in diameter so that the tip of the absorber 2 is exposed.
Is formed, and the diameter of the tip is reduced to such an extent that the inner cylinder 3 can push the absorber 2 out of the tubular film 6. Further, the tubular film 6 and the outer cylinder 3 are connected to each other by thermally welding the tip portion of the tubular film 6 to the groove 3A formed on the outer peripheral surface of the tip portion of the outer tube 3 and the entire outer peripheral surface of the tip portion. Has been done.

An expanded diameter opening 4B is formed at the tip of the inner cylinder 4, and the base end of the absorber 2 is press-fitted into the opening 4B so that the absorber 2 is integrated with the inner cylinder 4. However, the absorber 2 is separable from the inner cylinder 4.

The tubular film 6 is made of a flexible sheet made of plastic and is made of a heat-shrinkable or stretchable material so long as it has a fit with the absorber 2. Examples of such a material include synthetic resins such as polyethylene, polypropylene, polyethylene terephthalate, and nylon. The thickness of the tubular film 6 is preferably 10 to 200 μm, more preferably 40 to 100 μm.

Therefore, when using the tampon 1 in the state shown in FIG. 1 of the present embodiment, the tubular film 6 accommodating the absorber 2 is inserted into the vagina, and the inner cylinder 4 is pushed in, thereby absorbing the absorber 2. The inner cylinder 4 is separated from the absorbent body 2 by reaching the predetermined portion and inserting the inner cylinder 4 after the insertion and pulling out the inner cylinder 4 together with the outer cylinder 3 and the tubular film 6 from the predetermined portion as shown in FIG. The inner cylinder 4 and the outer cylinder 3 and the tubular film 6 can be easily taken out.

As described above, according to this embodiment, the thickness of the tubular film 6 which is the accommodating portion of the absorbent body 2 is thin, and the outer diameter thereof is substantially the same as that of the absorbent body 2. Therefore, the tubular film 6 accommodating the absorber 2 can be easily inserted, and after the insertion, the inner cylinder 4 can be pushed to push the absorber 2 out of the tubular film 6 and easily insert it into a predetermined portion. After the insertion, the inner cylinder 4 and the tubular film 6 can be taken out only by pulling out the outer cylinder 3 from the insertion position.

Further, the tampon of the other embodiment has the same structure as that of the above embodiment except that the structure of the inner cylinder 4 is different, as shown in FIGS. That is, in the inner cylinder 4 in the present embodiment, as shown in each of the drawings, the first inner cylinder 41 and the second inner cylinder 42 connected to and removed from the first inner cylinder 41 are telescopically configured. Therefore, the tampon 1 of this embodiment has a short and compact structure in which the second inner cylinder 42 is housed in the first inner cylinder 41 when not in use as shown in FIG. The opening of the inner cylinder 4 is the first inner cylinder 41.
41B is formed at the tip of the. When this is used, the second inner cylinder 42 is pulled out from the first inner cylinder 41 from the tampon 1 in the state shown in FIG. 3 to the state shown in FIG. 4, and thereafter the same operation as in the above embodiment is performed. Then, the absorbent body 2 is inserted into a predetermined site in the vagina as shown in FIG.

Next, one embodiment of the tampon manufacturing method of the present invention for manufacturing each tampon 1 will be described.

First, after the take-out string 5 of the absorbent body 2 is passed through the path 4A of the inner cylinder 4, one end (base end) of the absorbent body 2 is inserted into the inner cylinder 4.
The absorber 2 is integrated with the inner cylinder 4 by press-fitting it into the opening 4B at the tip of the absorber. Then, the absorber 2 is attached to the tubular film 6 formed to have a diameter slightly larger than the outer diameter of the absorber 2 (usually, the outer diameter of the absorber +0.5 to 2 mm).
The absorbent body 2 is covered with the tubular film 6 by inserting the absorbent body 2 from the tip to a position where it is exposed a little. After that, when hot air is applied to the tubular film 6 to heat and shrink the tubular film 6 (usually, the outer diameter of the absorber is −0.5 to 5 mm), the tubular film 6 adheres to the absorber 2. And integrate. Further, with the groove 3A of the outer tube 3 covered with the base end of the tubular film 6,
The tampon 1 can be manufactured by thermally welding the base end portion to the groove 3A and connecting the tubular film 6 to the outer cylinder 3 in series. Further, the tampon 1 shown in FIG. 3 can be manufactured according to this.

As another embodiment of the tampon manufacturing method of the present invention for manufacturing the tampon 1, the groove 3A of the outer tube 3 is first covered with the base end of the tubular film 6. The base end portion is heat-welded to the groove 3A and the tubular film 6 is continuously provided on the outer cylinder 3. Next, after inserting the inner cylinder 4 into the tubular film 6 and the outer cylinder 3 connected to the tubular film 6, the take-out string 5 of the absorber 2 is passed through the path 4A of the inner cylinder 4, and further,
