Referring to FIG. 3A, the straw 30, the inlet 30b, the outlet 30a, the body portion 39, the body portion 39a, the container 200, the blocking portion 301, and the support portion 302 are Is shown.

Body portion 39 is used to the elastic material, consisting of a tubular. Therefore, the liquid or gas can pass through. An inlet 30b is formed at one end of the body portion 39, and an outlet 30a is formed at the other end. The inlet port 30b is an inlet into which a liquid, such as a beverage, enters into the container. The liquid entering the inlet port 30b comes out through the outlet port 30b.

The body portion 39 is provided with a blocking portion 301 and a support portion 302. The blocking part 301 is located between the inlet 30b and the outlet 30a, and is preferably formed close to the outlet 30a. The support 302 is preferably formed between the inlet 30b and the blocking portion 301. Meanwhile, when the straw 20 is inserted into the container, the blocking part 301 and the support part 302 should be positioned so as not to be inserted into the container.

The blocking unit 301 serves to prevent the back flow of the liquid, that is, the beverage in the container. As shown in an enlarged cross-sectional view of portion B of FIG. 3A, the blocking portion 301 of the present embodiment is in the form of a groove formed by removing a portion of the body portion 39. As shown in the enlarged cross-sectional view of B of FIG. 3A, the groove formed in the blocking part 301 is formed by partially removing the outer wall of the body part 39, but a part of the inner wall may be removed. When the groove is formed in this way, the body portion 39 is easily folded in the blocking portion 301. That is, the groove formed in the blocking portion 301 and the support portion 302 serves to easily fold in its position when the body portion 39 is folded by folding. Therefore, the shape does not matter. It may be a wedge-shaped groove. In addition, in the manufacturing process, it is a position folded in advance using a press or other mechanism in advance, it is formed to be easily folded when the user later folds, or formed in a certain shape such as a dotted line or a straight line so that the user can easily identify the position It may be a mark. In addition, in the case of Figure 3a, but the blocking portion 301 is formed only on a portion of the body portion 39, all of the outer peripheral surface of the body portion 39 may be formed in an annular shape. However, in this case, since the restoring force of the body portion 39 is not good, it is preferable to form the blocking portion 301 with a groove or the like only as much as possible.

The support part 302 supports the folded body part 39 when the body part 39 is folded in the blocking part 301. The shape of the support part 302 is the same as the enlarged sectional view of A of FIG. 3A. The support 302 is folded when the body portion 39 in the form of a hook (hook), the folded body portion 39 is caught by the support portion 302 of the hook shape is not restored again. Figure 3b is a diagram illustrating the use of a disposable straw according to a first embodiment of the present invention, as shown in the figure, after folding the outlet 30a of the body portion 39 relative to the blocking portion 301, It is to be coupled to the support 302 to fix it. Looking at the enlarged cross-sectional view of the portion D shown in Figure 3b, the body portion 39a is the body portion 39 is folded and the space is blocked. On the other hand, in the enlarged cross-sectional view of C can be seen that the body portion 39 is fixed by the support portion 302. The support 302 should be formed in the body portion 39 at a point closer to the outlet 30a based on the blocking portion 301. The support 302 may be modified in various forms as long as it can fix the body 39 to maintain a folded form.

3C is a perspective view of the straw 30 coupled to the container 200. When the straw 30 is coupled as shown in the drawing, the possibility that the beverage inside the container flows out of the outlet 30a of the straw 30 disappears.

On the other hand, when the straw 30 of the shape as shown in FIG. 3c is coupled to the container 200, a gap is formed between the coupling portion 200a and the straw 30, and the drinking water in the container 200 flows out between the gaps. Can be. Therefore, measures should be taken to prevent this.
