Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an insertion device for use in inserting a sanitary tampon into the vaginal cavity.

Conventionally, this type of insertion tool has been put into practical use, consisting of an outer cylinder for accommodating a tampon and an inner cylinder slidably inserted into the outer cylinder for pushing out the tampon inside the outer cylinder. However, it was generally quite long and bulky, making it inconvenient for packaging and carrying.

The purpose of the present invention is to eliminate the above-mentioned drawbacks, and the gist of this invention lies in that the inner cylinder, which is slidably inserted into the outer cylinder, is configured to be bendable. The explanation based on the illustrated embodiment is as follows.

1, 2, and 3 show the basic structure of the insertion device of the present invention, which consists of an outer tube 1 and an inner tube 2 slidably inserted into the outer tube 1. The constituent material is resin.

The outer cylinder 1 is formed into a circular shape, and has radial notches 4 on its distal end surface that expand into a petal shape when the tampon 3 housed therein is pressed by the inner cylinder 2, allowing the tampon 3 to be pushed out. The small diameter portion 6 is formed through the stepped portion 5.

The inner cylinder 2 consists of a pressing head 7 and a pressing rod part 8.

The pressing head 7 has a stepped portion 9 which engages with the stepped portion 5 to prevent it from coming off from the rear end of the outer cylinder 1.

The pressing head I and the pressing rod part 8 are divided into rings, leaving a connecting part 10 to which a part of these materials is connected.

In the insertion device of the present invention having such a configuration, the pressing rod portion 8 is bent in parallel to the side surface of the outer cylinder 1 via the connecting portion 10 as shown in FIG. Raise the tampon 3 in line with the compression head 1 and press the inner cylinder 2.
When extruding from the outer cylinder 1, the extrusion operation may become unstable because the pressing rod part 8 is separated from the pressing head 7 in a ring-shaped manner, leaving a bulge in the connecting part 10.

Therefore, as shown in FIGS. 4A and 4H, there is a gap between the rear end surface of the tampon 3 inside the outer cylinder 1 and the tip edge of the pressing head 7, or between the inner surface of the front end of the outer cylinder 1 and the front end surface of the tampon 3. The distance is between the rear end edge of the outer cylinder 1 and the pressing head 7. It is not larger than the distance L2 between the pressing rod part 8 and the ring-shaped joint edge.

In this case, as shown in FIG. Since it is located inside, the outer cylinder 1
serves to jointly hold the joint edges together.

The extrusion operation does not become unstable.

5A, B, and C show means for preventing the extrusion operation from becoming unstable.

That is, in the embodiment shown in FIG. 5A, the connecting portion 100
A locking claw portion 11 is provided on the round-shaped joint edge of the pressing rod portion 8 located on the opposite side, and when the pressing rod portion 8 is raised as shown in FIG. Locking recess notch 1 that engages with
2 is provided at the ring-shaped joint edge of the pressing head 7.

@5 In the embodiment shown in FIGS. B and C, a locking claw portion 13 is provided at the round-shaped joint edge of the pressing rod portion 8 located on the opposite side of the connecting portion 10, and as shown in FIG. A locking claw portion 14 that faces and engages the locking claw portion 13 when raised is provided on the inner surface of the ring-shaped joint opening of the suppressing head 7.

In the embodiment shown in the fifth diagram, when the pressing rod part 8 is raised as shown in FIG. 15 is provided.

The positional relationship between the locking claws 1-Li2 and 14 and the locking recessed portion 12 may be opposite to that shown in the drawings.

16 in the diagram of the housing is a protruding rib provided on the outer periphery of the small diameter portion 6;
Reference numeral 17 indicates a drawer string for the tampon 3.

As mentioned above, according to the insertion tool of the present invention, the inner cylinder 2 is divided into the pressing head 7 and the pressing rod part 8 in a ring shape, and the head and the rod part can be bent by the connecting part 10. Since it is connected to the outer cylinder 1, the rod can be bent in parallel with the outer cylinder 1 when packaging and carrying it, and the overall length can be shortened to the extent that it can be almost completely stored in the palm of the hand, which is extremely convenient. It is useful for practical use.
