Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an applicator type tampon inserter.

[Prior Art] As this type of tampon inserter, for example, the
As shown in the figure, an inner cylinder 21 which accommodates a tampon 22 and also serves as an extrusion member is slidably fitted into an outer cylinder 20 having a tampon extrusion port 20a at the tip, and an inner cylinder 21 on the side wall of the outer cylinder 20 Insert the tampon 22 into the inner tube 21.
A protrusion 23 is provided for pushing out from the inner cylinder 20 into the outer cylinder 20, and a guide groove 24 into which the protrusion 23 fits is provided on the side wall of the inner cylinder 21. When in use, as shown in FIG. The protrusion 23 is attached to the front edge of the guide groove 24.
Push the tampon 22 inside the inner cylinder 21 into the outer cylinder 20 by the protrusion 23 by pulling it backward as much as possible until it locks, and then push the inner cylinder 21 into the outer cylinder 20 again. By the above tampon 2
2 is extruded into the body cavity from the extrusion port 20a (see Japanese Utility Model Application No. 59-5920).

In such a tampon inserter, if the guide groove 24 is directed downward during use, the fifth
As shown in the figure, the string 25 of the tampon 22 hangs down into the guide groove 24, and when the inner tube 21 is pushed in, the string 25 is between the inner tube 21 and the outer tube 20 at the rear end of the guide groove 24. Easy to get caught in. If the insertion tool is removed in this state, the tampon 22 will also be pulled out.

[Problems to be Solved by the Invention] The technical problem of the present invention is to provide a tampon inserter in which the string of the tampon is not caught between the inner tube and the outer tube.

[Means for Solving the Problems] In order to solve the above problems, the tampon inserter of the present invention includes an inner cylinder that houses a tampon and also serves as an extrusion member inside an outer cylinder that has a tampon extrusion opening at the tip. The outer cylinder is slidably fitted, and has a protrusion on the inner surface of the side wall of the outer cylinder for pushing the tampon from the inner cylinder into the outer cylinder, and a guide groove in which the protrusion fits into the side wall of the inner cylinder. The guide groove is characterized in that the guide groove is formed to a length such that the rear end portion thereof is exposed from the outer cylinder at the maximum pushing position of the inner cylinder.

[Effect of the invention] Since the guide groove is formed to such a length that the rear end is exposed from the outer tube at the maximum pushing position of the inner tube, even if the tampon string hangs down inside the guide groove, When the inner cylinder is pushed in, the tampon will not be caught between the inner cylinder and the outer cylinder, and therefore the tampon can be pushed out reliably.

[Example] Hereinafter, an example of the present invention will be described in detail based on the drawings. In FIGS. 1 and 2, 1 is an outer cylinder made of a flexible material such as synthetic resin;
is an inner cylinder made of the same material as the outer cylinder 1.
An inner tube 2 is slidably fitted therein, and a tampon 3 is housed inside the inner tube 2.

The outer tube 1 has a tampon ejection port 4 surrounded by a plurality of petal-shaped divided pieces 1a at its tip, and the tips of these flexible divided pieces 1a are connected to the outer tube 1, respectively. They are smoothly curved toward the center and converge together to substantially close the extrusion port 4. A protrusion 5 for pushing out the tampon 3 from the inner tube 2 into the outer tube 1 is formed on the inner surface of the side wall at the rear end of the outer tube 1.

On the other hand, the inner tube 2 also serves as a pushing member for pushing out the tampon 3 from the outer tube 1 into the body cavity, and has a guide groove 6 on its side wall in which the projection 5 is movably fitted. A stopper 7 is provided on the rear outer circumferential surface of the inner cylinder 2 to abut and lock the rear end of the outer cylinder 1 to define the maximum pushing position when the inner cylinder 2 is pushed in. The length is such that the rear end of the inner cylinder 2 is exposed from the rear end of the outer cylinder 1 at the maximum pushing position. The exposed length of the guide groove 6 at this time needs to be set to a size that allows the string 8 of the tampon 3 to be freely inserted therein.

When using the above tampon inserter, please make sure that the inner tube 2
As shown in FIG.
The tip of the tampon 3 comes into contact with the rear end of the tampon 3 and presses the tampon relatively forward, and the tampon 3
extruded inward.

Subsequently, when the inner cylinder 2 is pushed into the outer cylinder 1 again, the tip of the inner cylinder 2 presses the rear end of the tampon 3, and the tampon 3 pushes open the divided piece 1a and is extruded from the extrusion port 4. Ru.

When the inner cylinder 2 is pulled out rearward, the tampon string 8 fits into the guide groove 6 as shown by the chain line in FIG. Even if the cylinder 1 is pushed to the maximum pushing position (Figs. 1 and 2) where it abuts and locks the rear end of the cylinder 1, the rear end of the guide groove 6 is exposed from the outer cylinder 1, so the inner cylinder The string 8 is not caught and locked between the tampon 2 and the outer cylinder 1, so that even if the insertion tool is removed after the tampon 3 has been pushed out, the tampon 3 will be pulled out together with the insertion tool. Never happened. In this case, it is more effective if the rear end of the guide groove 6 is formed into an arc shape as shown in FIG.

Incidentally, as shown by the chain line in FIG. 1, an arc-shaped notch 9 may be provided at the rear end of the outer cylinder 1 to face the rear end of the guide groove 6.
