Description

[Detailed description of the invention] (1) Industrial application field This invention relates to a tampon inserter used for women's menstrual treatment.

(2) Prior Art The tampon inserter shown in Figs. 1 and 2 is known as this type of tampon inserter. An outer cylinder 1, 1' which is closed with a petal-shaped divided piece and has check claws 1a, 1'a at opposite positions on the inner wall of the rear end, and vertical grooves 2a, 2'a for inserting the check claws. The tampon ejector is comprised of an inner cylinder 2, 2' for extruding tampons which is fitted into the outer cylinder so as to be movable in the front and back direction, and tampons 3, 3' housed within the inner cylinders 2, 2'.

When the tampon inserter is not in use, the tampons 3, 3' are stored in the inner tubes 2, 2' as shown in FIGS. 1 and 2. When the inner cylinders 2, 2' are pulled out from the rear ends of the outer cylinders 1, 1' during use, the rear ends of the tampons 3, 3' stored in the inner cylinders are engaged by the check claws 1a, 1'a. The inner cylinder 2,
Remove the tampons 3, 3' by pulling out the inner tube until the front end of the tampon 2' comes off the rear end of the tampon 3, 3'.
is stored from inside the inner cylinders 2, 2' to inside the outer cylinders 1, 1',
Thereafter, by pressing the rear ends of the tampons 3, 3' with the front ends of the inner cylinders 2, 2', the tampons 3, 3' expand the divided pieces from the front ends of the outer cylinders 1, 1' and are pushed out. It's starting to become easier.

(3) Problems to be solved by the invention By the way, the above-mentioned tampon inserter has check claws 1a and
1'a, it is also necessary to provide a pair of vertical grooves 2a, 2'a, through which the pair of non-return claws are inserted, at opposing positions in the inner cylinders 2, 2'. Therefore, it is undeniable that the strength against vertical force becomes weak in the peripheral walls of the inner cylinders 2, 2' where the vertical grooves 2a, 2'a are provided, and the front end of the inner cylinders 2, 2' When pushing out the tampons 3, 3' stored inside, the inner cylinder 2,
There was a problem in that the peripheral wall 2' was easily bent, making it very difficult to push out the tampon. Also,
As mentioned above, the outer cylinders 1 and 1' have check claws 1a and 1'a.
are provided in a pair facing each other so as to protrude into the inner cylinders 2, 2' from the vertical grooves 2a, 2'a, so that the inner cylinders 2, 2' can be viewed not only from the front end side but also from the rear end side. To,
It was difficult to insert a tampon with an outer diameter that matched the inner diameter of the inner cylinder, and it was inevitable to insert a tampon with a diameter smaller than the inner diameter of the inner cylinder by the height of the two check claws 1a and 1'a that protruded into the inner cylinder. In addition to not being able to be inserted, the structure is complicated due to the two non-return claws 1a and 1'a as mentioned above, and the cost is relatively high for a disposable product. .

Therefore, this idea prevents the strength of the vertically grooved peripheral wall of the inner tube from weakening against vertical forces, and allows the inner tube to fully perform its function as a tampon extruder. To provide a tampon insertion tool which allows a tampon whose inner diameter substantially matches the inner diameter of the tampon to be easily inserted from the rear end side.

(4) Means for solving the problems In order to solve the above problems, the tampon inserter of this invention is characterized by adopting the following technical means. That is, in the tampon inserter as described above, the outer cylinder has only one plastic non-return claw on the inner wall, and this non-return claw has a hook shape with the tip thereof slanted toward the front end of the outer cylinder. In addition, the inner tube has only one vertical groove for inserting the non-return claw, and this vertical groove does not penetrate to the front end of the inner tube. When the cylinder is pulled out from the rear end of the outer cylinder, it is engaged with a non-return claw.

(5) Effect By adopting the above-mentioned technical measures, it is possible to double the strength of the inner cylinder against longitudinal force compared to conventional ones, and therefore, the inner cylinder can be used for extruding tampons. It becomes possible to fully demonstrate the function. In addition, only one non-return claw is provided on the inner wall of the outer cylinder, and this non-return claw is made of plastic and elastically displaces so as to approach the inner wall of the outer cylinder. A tampon that matches the inner diameter of the inner cylinder can be easily inserted into the inner cylinder.

(6) Example In FIGS. 3 and 4, the front end of the outer cylinder 11 is
It is closed by a plurality of petal-shaped segments 11a having elasticity and flexibility. As shown in FIG. 5, on the inner wall of the rear end of the outer cylinder 11, there is one hook-shaped check claw 11b made of plastic, whose tip is integrally inclined toward the front end of the outer cylinder 11. It is formed. As shown in FIG. 6, the circumferential wall of the pressing inner cylinder 12 is formed with one vertical groove 12a for inserting a check claw, which communicates the inside and outside of the inner cylinder 12 without penetrating to the front and rear ends of the inner cylinder 12. With the check claw 11b inserted into the longitudinal groove 12a, the inner cylinder 12 is inserted into the outer cylinder 1.
1 from the rear end opening so as to be movable in the front and rear directions. When the inner cylinder 12 is pushed into the outer cylinder 11, the check claw 11b is inserted into the vertical groove 12a.
As the inner cylinder 12 is pulled out from the outer cylinder 11,
When the non-return claw 11b is moved relatively forward within the vertical groove 12a and the non-return claw 11b comes into contact with the frontmost end of the vertical groove 12a, the inner cylinder 12 is no longer pulled out. There is. At this time, the check claw 11b
The distal end of the inner cylinder 12 is at the same level as the front end of the inner cylinder 12, or is at a position that projects slightly.

As shown in FIG. 3, a tampon 13 is housed in the inner cylinder 12, and the check claw 11b is located behind the tampon 13. Also 1 tampon
Tampon removal string 14 fastened to the rear end of 3
is in a state where it is pulled out from the rear end opening of the inner cylinder 12.

When using the tampon inserter, first pull out the inner tube 12 from the rear end of the outer tube 11, then the fourth
As shown in the figure, the non-return claw 11b is moved relatively forward within the vertical groove 12a and is locked to the rear end of the tampon 13, and the inner tube 12 is further pulled out to prevent the tampon 13 from non-returning. It is pressed by the claw 11b and is housed in the outer cylinder 11 from inside the inner cylinder 12. After that, when the inner tube 12 is pushed into the outer tube 11 again, the front end of the inner tube 12 presses the rear end of the tampon 13, and the tampon 13 pushes out the divided pieces 11a and is pushed out from the outer tube 11. .

FIG. 7 shows another embodiment of an inner cylinder 12' in which a vertical groove 12'a for inserting a non-return pawl is formed into a fan shape so that the rear end side is wider than the front end side. If the vertical groove 12'a of the inner cylinder 12' is formed in this way, the non-return claw 1 of the outer cylinder 11 can be removed when assembling the tampon inserter.
1b can be easily inserted into the vertical groove 12'a, making assembly easier.

(7) Effects of the invention This invention is as described above, and the strength of the inner cylinder against vertical force is stronger than that of conventional ones, and this also impairs the tampon extrusion function of the inner cylinder. As a result, the inner cylinder allows the tampon to be pushed out smoothly and reliably by expanding the divided pieces from inside the outer cylinder. Since there is no such thing, commercialization, which has been difficult to realize, can be achieved. In addition, a tampon with an outer diameter that matches the inner diameter of the inner cylinder can be easily inserted into the inner cylinder from the rear end side.
Therefore, there is no need to make the inner diameter of the inner tube or the inner diameter of the outer tube that fits into the inner tube larger than the outer diameter of the tampon, and the tampon inserter can be made more compact. Furthermore, the structure is significantly simpler than conventional ones, and it has excellent effects such as being able to reduce the cost of disposable items.
