この発明は、内側ストロ−及び外側ストロ−からなる摺
動式の伸縮ストロ−の改良に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement in a sliding telescoping straw consisting of an inner straw and an outer straw.
（従来の技術）
飲料用容器に付着させるストロ−は、飲用の際に容器内
に落ら込んでしまわないよう、飲料用容器の深ざよりも
長いものであることが望ましい。(Prior Art) It is desirable that a straw attached to a beverage container be longer than the depth of the beverage container so that the straw does not fall into the container during drinking.

様な問題を生じていた。However, since a straw of a length that is not inconvenient for drinking is longer than the beverage container itself, it is impossible to attach it to the beverage container. Therefore, it becomes necessary to attach a retractable straw that is in a contracted state when attached and expands when drinking. This telescopic straw has a double structure consisting of an inner straw and an outer straw, and the diameter of the outer straw is reduced at the joint, and the inner straw is
Since it is simply a diameter-enlarged end, the following problems have conventionally occurred.

。In other words, a telescopic straw is extended and inserted into a beverage container to drink.
When extending the straw, correct handling can be achieved by extending the inner straw in the normal extension direction, that is, toward the tip, but if you inadvertently extend it in the opposite direction, the inner straw may be pulled out from the outer straw. In addition, the conventional straw drawers mentioned above had no means to reliably maintain the extended state, that is, to prevent the straw from easily contracting again, so it could be accidentally drawn while drinking. There was a risk that if the straw was pushed and contracted, the straw would fall into the container.

いる。Conventionally, in view of the above points, it has been proposed to prevent the inner straw from being easily pulled out from the outer straw, and to maintain the extended state without easily contracting once the straw has been extended. For the purpose of so that it engages with the tip of the outer straw,
Furthermore, an inward stopper is formed near the tip of the outer straw, for example at the boundary between the outer straw body and the reduced diameter portion, to prevent the inner straw from being drawn in.
In order to prevent the straw from being pulled out, a telescopic straw in which a diameter-reduced portion is also formed at the proximal end of the outer straw has been developed and is well known.

。(Problems to be Solved by the Invention) This known telescoping straw is very good in that the inner straw does not come out, and in the extended state, the inner straw does not enter into the outer straw and contract. However, since the stopper that prevents the inner straw from being drawn in in the extended state is formed as an inward stopper on the outer straw, when the inner straw is pulled out from the outer straw and extended, the inner straw is There is a problem in that it is difficult to determine the position where the rear end of the inner straw passes over the above stopper of the outer straw when it is pulled out, and as a result, the inner straw is pulled out forcibly and the inner straw is pulled out from the outer straw. There was also the problem that it would come out.

である。In view of the above-mentioned problems, this invention allows the final position of the inner straw to be visually confirmed when the inner straw is pulled out from the outer straw and extended, and the inner straw is pulled out at the most suitable position. The purpose of this invention is to provide a new retractable straw that can be retracted.

で効果的である。The inner straw body 1 is inserted into the outer straw body 8, and in the illustrated embodiment, the outer diameter of the inner straw body 1 is set at the tip of the outer straw body 8 so that the inner straw body 1 can easily expand and contract. The dimension is slightly smaller than the inner diameter of the detail 11. When the inner straw body 1 is pulled out from the tip of the outer straw body 8 and extended,
At the final stage, after the positioning protrusion 4 pushes out the tapered part 11 of the outer straw 0-8 and passes through, the inner straw body 1 is expanded in the intermediate diameter so that the inner straw body 1 is not pulled away from the outer straw body 8. The outer diameter of the portion 5 is made slightly larger than the inner diameter of the tip tapered portion 11 of the outer straw body 8, and when the intermediate enlarged diameter portion 5 and the tip tapered portion 11 overlap, the intermediate enlarged diameter portion 5 is set to the tip end. The details 11 are fitted together by expanding pressure. The positioning protrusion 4 is
The reason why the straw of the present application is made of a synthetic resin material is that it passes through the tapered part II by expanding it.
After the contact, the tapered portion 11 and the intermediate enlarged diameter portion 5 are brought into close contact with each other by contracting and restoring, which is effective in ensuring that the airtight condition is maintained at this portion.

この先細部１１を通過する。The telescoping straw of the present invention having the above-mentioned configurations is similar to previously known telescoping straws; before use, the inner straw body 1 is housed within the outer straw body 8, and as shown in FIG. The tip of the main body 1 slightly protrudes from the outer straw main body 8. When in use, the inner straw body 1 can be pulled out by pinching the tip and pulling it out from the outer straw body 8, and at the final pull-out position,
11] When the positioning protrusion 4 of the inner straw body 1 reaches the tapered part 11 of the outer straw body 8, the drawer becomes heavy. If the force is increased and the straw is pulled out, the positioning protrusion 4 pushes out the tapered part 11 of the outer straw 8 and passes through this tapered part 11.
