"Example" Part 1 FIGS. 1 to 8 show an example of implementation.

In the figure, 1 is an insertion tube, and 2 is a push rod installed at the rear of the insertion tube, and these are made of synthetic resin as appropriate.

The insertion tube 1 is made of flexible synthetic resin and is formed to have a required diameter suitable for the tampon A and a required length suitable for insertion, and has a spherical tip 11 and radial cuts 12 at the tip. A plurality of guide protrusions 13 in a cylindrical direction are arranged at equal intervals on the inside of the rear end.

The press rod 2 consists of an outer cylinder 21 that is slidably fitted inside the plurality of guide protrusions 13, and an inner cylinder 22 that is movably fitted inside the outer cylinder.

The outer cylinder 21 is formed into a cylinder approximately half the length of a conventional single push rod, and has an outward flange 2 at the tip.
11 is provided so that the outward flange is slidably fitted into the insertion tube 1 and is abutted against the inner end of each guide protrusion 13 to prevent it from coming off. In addition, one strip in the circumferential direction on the outer periphery of the upper part, and several strips (equally spaced) in the cylindrical direction on the inner periphery are provided to prevent the free movement of the inner tube 22. They are trying to prevent free movement.

The inner cylinder 22 is formed into a rectangular cylinder with a slightly long length whose ridge matches the inner diameter of the outer cylinder 21, and has a circular outward flange 221 at the tip that is flush with the ridge, and has a finger hook at the end. A projecting edge 222 is provided.

Therefore, a locking means 3 is provided between the distal end of the outer cylinder 21 and the front end of the inner cylinder 22, and the locking means:
Inside the outer cylinder 21, at its end, a pair of front and rear retaining locking claws are slidably brought into contact with the flat front and rear surfaces of the inner cylinder 22, respectively, and prevent the outward flange 221 from coming off. 31, 31, and near the ends thereof, a pair of left and right detents are slidably abutted against the flat left and right surfaces of the inner cylinder 22, respectively, and are engaged over the outward flange 221. Stopper claws 32, 32
is provided so that the outward flange 221 can be held between the retaining pawls 31, 31, and slits 33, 33 are formed in the outer cylinder 21 on both sides of the detent pawls 32, 32, respectively. , each of the detent locking pawls 32, 32 is made elastically deformable for climbing engagement.

As shown in Fig. 1, the tampon A is placed inside the insertion tube 1, the string is passed through the push rod 2, and the inner tube 22 of the push rod 2 is retracted. As a product.

Next, when putting it into use, first, the inner cylinder 2
2 is fully pulled out by hooking the finger on the finger hook ridge 222 to activate the locking means 3. As a result, push rod 2
is sufficiently long like the conventional one,
It can be used without any problems.

Part 2 9 to 13 show other examples.

In this case, in the previous example, the slits 33, 33 of the outer cylinder 21 of the push rod 2 are
4,34. The rest is almost the same as the previous example, and the explanation will be omitted.

"Effect of the invention" According to the invention, when the tampon A is stored in the insertion tube 1 and the string is passed through the push rod 2, and the inner tube 22 of the push rod 2 is not yet pulled out. In this state, the outer tube 21 is fitted and held by the plurality of guide protrusions 13 at the rear end of the insertion tube 1, and the outward flanges 211 at the tip of the outer tube 21 are The inner ends of the guide protrusions 13 are abutted to prevent them from coming off, and furthermore, the fitting protrusions 212 provided on the outer periphery of the upper part of the outer cylinder 21 are fitted into the inner surfaces of the guide protrusions 13 in a state of biting, so that the outer Cylinder 21 and inner tube 2
2 are prevented from free movement, so even if the press rod 2 is in the contracted state, the press rod 2 will not cause any inconvenient fluctuations in the product distribution process, and of course will not protrude unsteadily for a long time. There will be no damage.
