Detailed Description of the Invention "Field of Industrial Application" The present invention consists of an outer tube and an inner tube inserted into the outer tube, and when swallowing, the inner tube is pulled out from the outer tube to extend its length. The present invention relates to a two-stage straw for use.

``Prior Art'' FIGS. 6 and 7 show a conventional two-stage straw, in which reference numeral 1 indicates an inner tube and reference numeral 2 indicates an outer tube. Conventional 2
The stepped straw is formed by tube bodies having considerably different diameters, ie, inner and outer tubes 1 and 2 h.

For this reason, one end 2a of the outer tube 2 was formed with a tapered portion 2b whose diameter was gradually reduced until it came into contact with the circumferential surface of the inner tube 1. Further, a backstopping stopper 2d that protrudes inward is formed near one end 2a of the outer tube 2. With respect to such an outer tube 2, the other end 1a of the inner tube l is provided with a stopper/sealing portion 1 whose diameter is gradually expanded to such an extent that it is loosely inscribed in the outer tube 2.

In use, such a conventional two-stage straw has an inner tube 1 housed within an outer tube 2, as shown in FIG. When using this straw, the inner tube 1 is pulled out from the outer tube 2 to extend its length. Then, as shown in FIG. 7, the stopper-cum-sealing portion 1b of the inner tube 1 engages with the anti-backward stopper 2d of the outer tube 2, thereby pushing the extended straw. In addition, the stopper and sealing part 11 of the inner tube l

``Problems to be Solved by the Invention'' In such a conventional two-stage straw, there is a stopper and seal of the inner tube 1 between the tapered part 2b of the outer tube 2 and the reverse prevention stopper 2d. Either the inner tube l and the outer tube 2 are thin and delicate, so the stopper-cum-sealing portion 1b and the anti-backward movement stopper 2d are fitted together to prevent the inner tube l from moving back and forth during expansion. , it is difficult to accurately form the taper portion 2b, etc., and for this reason, the conventional two-stage straw cannot securely fix the inner tube 1 during expansion.
That is, there was a problem in that the stopper properties were poor.

For this reason, in conventional two-stage straws, the inner and outer tubes are 1.
There is a problem that the airtightness of 2 cannot be sufficiently improved, and when in use, outside air flows in through the gap between the inner and outer tubes 1.2, making it impossible to drink the beverage smoothly and causing an unpleasant feeling of use. .

Furthermore, in such a two-stage straw, one end 2a of the outer tube 2 and the other end 1a of the inner tube 1 must be processed into a predetermined shape, and then the outer tube 2 and the inner tube 1 must be assembled. There wasn't. For this reason, the conventional two-stage straw has the disadvantage that it takes time and effort to manufacture, making it difficult to reduce manufacturing costs.

``Means for Solving the Problems'' Therefore, in the two-stage straw of the present invention, the inner and outer tubes are formed by tube bodies that are in close contact with each other, and the two tubes are spaced apart in the axial direction of the peripheral wall of the outer tube. Recesses of the same shape reaching the inner tube are provided at two locations on the peripheral wall of the inner tube, and recesses that fit into convex portions formed on the inner wall of the outer tube by the recesses of the outer tube are provided at two locations on the outer tube. The above-mentioned problem was solved by providing the four parts spaced apart in the axial direction by the same distance as the four parts.

As the latter method of simultaneously molding the combined inner and outer tubes 11 and 12, there is a thin-walled double tube manufacturing method previously proposed by the present inventors (filed on September 30, 1988). In this method, an inner tube 11 is extruded by a first extruder, and while a fluid such as air is fed into the inner tube 11, the inner tube 11 is placed in the center of a die of a second extruder. The inner tube 11 is guided into the provided through hole and is molded by this second extrusion molding machine.
This is a method of manufacturing a double tube by extruding the material that will become the outer tube 12 on the outer periphery of the outer tube, and then immediately cooling the material that will become the outer tube 12 while sucking it from the outer periphery. By appropriately cutting the tube, a double tube consisting of a combination of inner and outer tubes 11 and 12 of a predetermined length can be obtained.

When manufacturing the two-stage straw of the above embodiment, the tips of the upper and lower heaters 22a, 22b are formed into a substantially V-shape, and the double tube is
Either the heaters 22a and 22b are rotated an appropriate number of times between the heaters 22a and 22b, or the heaters 22a and 22b are rotated and moved intermittently between the heaters 22a and 22b. The inner and outer tubes of the double tube passed through this device 11.
12, as shown in FIG.
12a, 12a are formed at the same time, thereby manufacturing the two-stage straw of the present invention.

In the two-stage straw of the present invention, the inner tube 11 is manufactured separately.
.. When manufacturing after combining the outer tube 12, use an inner tube 11 that is longer than the outer tube 12.
It is possible to manufacture a two-stage straw that can be easily pulled out. Further, it is possible to process the tip only at the end of the inner tube 11.

On the other hand, when the double tube manufacturing method previously proposed by the present inventors is used, the gap between the inner and outer tubes 11 and 12 is extremely small, resulting in a two-stage straw with very little air leakage. Obtainable. Another advantage is that there is no need for a step of assembling the inner and outer tubes II and 12 during manufacturing. When cutting the above double tube to form the inner and outer tubes 11 and 12, the inner and outer tubes 1
1.12 become the same length, making it difficult to pull out the inner tube 11. In such a case, the inner and outer tubes 11.12 are sharpened, and the inner tube 11 is rotated 180° within the outer tube 12.
As shown in FIG. 4, the ease of drawing out the inner tube 11 can be improved by looking through the end of the inner tube 11 from the end of the outer tube 12.
