のストローを提供することを目的とする。In addition, recently, beverages such as milk and fruit juices have come to be packaged in small paper containers, such as plastic containers. A straw, which is attached to a diagonal line on one side of the medium-sized paper container, is inconvenient because it is approximately the same length as the length of the diagonal line, as it is too short to suck and drink the beverage contained in the small paper container. The present inventor conducted research on a drawer-type (extendable) straw that can be used as a straw for attaching to small paper containers and is also useful as a portable straw. , the present invention has been achieved. The present invention has an inner tube inserted into and taken out from an outer tube, and even when used for prick-tie small paper containers, for example, the inner tube can be pulled out or pushed out from the outer tube to extend the straw. To provide a drawer-shaped straw that can be fixed to easily suck and drink a beverage in a small paper container.

破ることができるのである。Also, ``4,'' refers to a locking part in the form of a latching mechanism. ``The locking part 4 is a ring-shaped locking part in which a groove with a V-shaped cross section is formed in the front part of the outer tube A. However, the locking part indicated by 4 is not formed in a circular shape, but is a locking part in which 0 protrusions with a V-shaped cross section are provided at appropriate intervals on the same circumference. In both cases, the rear wall is gently sloped, the front wall is approximately vertical, and the valley (bottom)
The diameter (distance) of the inner pipe A is slightly larger than the outer diameter of the main body shell, and the outer diameter of the rear end entrance part of the hopper opening part 2 (formed to be larger than the outer diameter of the main body shell). Since the hopper closing part 2 is formed to be smaller than the locking part 4 (4,) when pulling out the inner tube A to the use condition, the hopper closing part 2 can easily get over the locking part 4 (4,), When asked, ``
The rear end entrance edge of the hopper entrance part is locked on the front wall of the locking part, and the inner tube A is stopped so as not to move backward into the outer tube B. In addition, the shape of the machine cross section of the locking part is not only the shape described above, but also the shape of the cross section and the depth of the valley (height of the inward protrusion 6) to enable the above-mentioned climbing and reverse stopping.
can be changed as appropriate. According to the present invention, the front end portion of the outer tube is formed into a funnel-shaped shape including a hopper-shaped portion provided at the front end of the locking portion and a tube body portion provided at the front end of the hopper-shaped portion. The pipe body is closely aligned with the inner pipe main body, and the inner surface of the hopper-shaped portion has a diagonal shape (sea-bowl shape) and the outer surface of the hopper-shaped opening at the rear end of the inner pipe. Because it is formed so that it is tightly strung, when the inner tube is pulled out from the outer tube until it is ready for use, the inner tube can be prevented from sliding sideways by the tube body, and can be firmly held in an airtight manner. Since the peripheral surfaces of the bowl-shaped body and the hopper-shaped closing part are brought into close contact with each other, the beverage can be sucked and drank, and since the locking part is provided, the inner tube does not move backwards, and the straw insertion opening can be closed. It can easily break through coatings (lids) made of aluminum or the like.
