The present invention relates to a straw, and more particularly, to a disposable straw with a content leakage prevention function.

Use a straw to easily drink the soda in the pack or a soda in a fast food restaurant. 1A and 1B are perspective views of a straw according to the prior art. FIG. 1A is a straight straw 10 and includes an inlet 12 for inserting into a container containing a drink and an outlet 11 for outflow of the drink. FIG. 1B is a straw 20 in which wrinkles 22 are additionally formed so as to drink beverage more effectively. The pleats 22 can be bent freely at a desired angle, allowing the consumer to conveniently drink beverages without bowing much head. On the other hand, these straws 10 and 20 are made of synthetic resin, and have elasticity and elasticity.

Figure 2a is a perspective view of the container according to the prior art, Figure 2b is a perspective view of the container of a disposable straw and pack according to the prior art. The container 200 in the form as shown in Figure 2a is referred to as a 'pack'. The body portion 201 of the pack is made of a thick paper material, the coupling portion 202 is formed on the top. Coupling portion 202 is made of a material of a relatively low strength, when to insert the straw 20 strongly torn. However, once the torn coupling portion 202 can not be restored to its original state, the consumer is forced to drink beverages in combination with the straw 20 as shown in Figure 2b.

At this time, if you drink all the drinks in the container 200 at a time, there is no problem, when drinking only a part of the drinking water to move to the outlet 20a, or the gap between the coupling portion 202 and the straw 20 Drinking water may flow between them. Therefore, the consumer had to carry the coupling part 202 and the straw 20 so that the container 200 might not fall, and it was necessary to be careful.

Furthermore, the container in the form of a pack 200 has a problem that the body is crushed well so that the beverage is more easily leaked by the pressure.

In addition, since the entire diameter of the straw 20 is the same, there is a problem in that the container 200 falls out well.

The present invention is intended to provide a disposable straw not only does not flow out of the drinking water to the outlet and the container coupling portion of the container, but also the straw from the container.

One side of the present invention is provided with a disposable straw including a tubular body portion, an inlet formed at one end of the body portion, an outlet formed at the other end of the body portion, and a fixing portion formed at the body portion between the inlet and the outlet. A straw can be used to secure the straw to the vessel.

The fixing part may include a first inclined portion having a diameter that increases in the inlet direction from the inlet direction, and a second inclined portion having a diameter that increases in the inlet direction in the outlet direction. Coupling grooves may be formed between the parts.

On the other hand, it may further include a first blocking portion formed in the body portion between the outlet and the fixing portion, and a second blocking portion formed in the body portion between the first blocking portion and the fixing portion. This block serves to prevent the drinking water from flowing out of the outlet. The first blocking portion and the second blocking portion may be formed by removing a portion of the body portion, or may be a mark formed to identify a position on the body portion. Furthermore, the first blocking portion and the second blocking portion may be formed diagonally with respect to the body portion.

Another aspect of the invention, the tubular body portion, the inlet formed in one end of the body portion, the outlet formed in the other end of the body portion, the inlet and the pleat formed in the body portion between the outlet and the inlet and the pleat A disposable straw is provided that includes a fixing portion formed on the body portion.

Hereinafter, an embodiment of a disposable straw according to the present invention will be described in detail with reference to the accompanying drawings. In the description with reference to the accompanying drawings, the same components will be denoted by the same reference numerals regardless of the reference numerals and redundant description thereof will be omitted.

3A is a perspective view and a partially enlarged cross-sectional view of a disposable straw according to a first preferred embodiment of the present invention. Referring to FIG. 3A, a straw 30, an inlet 30b, an outlet 30a, a body portion 39, a first blocking portion 301, and a second blocking portion 302 are shown.

Body portion 39 is used to the elastic material, consisting of a tubular. Therefore, it is a structure through which a liquid or gas can pass. 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 part 39 is provided with a first blocking part 301 and a second blocking part 302. The first blocking portion 301 is located between the inlet 30b and the outlet 30a, and is preferably formed close to the outlet 30a. The second blocking portion 302 is preferably formed between the inlet 30b and the first blocking portion 301. On the other hand, when the straw 20 is inserted into the container, the first blocking portion 301 and the second blocking portion 302 should be positioned so as not to be inserted into the container.

The first blocking portion 301 and the second blocking portion 302 serve to prevent backflow of the liquid, that is, the beverage in the container. 3A is an enlarged cross-sectional view, the first blocking portion 301 of the present embodiment is in the form of a groove formed by removing a portion of the body portion 39. In the drawing, the groove formed in the first blocking portion 301 is formed by removing an outer wall of the body portion 39, but a portion of the inner wall may be removed. Meanwhile, the second blocking unit 302 may also be formed in the same form as the first blocking unit 301. When the groove is formed in this way, the body portion 39 is easily folded in the first blocking portion 301 and the second blocking portion 302. That is, the groove formed in the first blocking portion 301 and the second blocking portion 302 serves to easily fold in the position when the body 39 is folded by folding. Therefore, the shape does not matter. It may be a wedge-shaped groove, as shown in an enlarged sectional view of FIG. 3C. In addition, in the manufacturing process, the position is pre-folded using a press or other mechanism in advance, so that when the user folds again later, it is formed to be easily folded, 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, although the first and second blocking portions 301 and 302 are formed in only a part of the body portion 39 in FIG. 3A, all of the outer circumferential surfaces 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 first and second blocking portions 301 and 302 with grooves or the like only as much as possible.

Figure 3b is an illustration of the use of a disposable straw according to a first embodiment of the present invention. As shown in the figure, when the straw 30 is inserted into the container in the inlet (not shown) direction, the first blocking portion 301 and the second blocking portion 302 are exposed to the outside. After drinking some of the beverage inside the container through the outlet 30a, when the rest is stored or moved, the first blocking part 301 and the second blocking part 302 are folded in the same direction as shown. As a result, the body portion 39 forms a triangular shape. At this time, as shown in the enlarged cross-sectional view of Figure 3b the inner wall of the body portion 39 of the first blocking portion 301 is in contact with each other to block the internal space of the body portion 39, so that liquid or gas can not move. The same applies to the second blocking unit 302. On the other hand, since the body portion 39 is made of a synthetic resin having a good elasticity, when the first blocking portion 301 and the second blocking portion 302 are left in a folded state, the restoring force to return to the original state as shown by the arrow of FIG. Occurs. Therefore, a force is needed to counteract this restoring force. In the present exemplary embodiment, when the first blocking part 301 and the second blocking part 302 are folded in a state in which the straw 30 is coupled to the container 200, the inlet port 30a of the straw 30 is opened on the container upper part ( Positioning at 200a cancels the restoring force. As a result, the first blocking part 301 and the second blocking part 302 are kept in a folded state, and the beverage in the container 200 is discharged back to the outlet 30a even when pressure is applied to the container 200. Will not be.

3D is a perspective view of a disposable straw according to a second preferred embodiment of the present invention,

In the present embodiment, unlike the first embodiment, the first blocking unit 301 and the second blocking unit 302 are formed in a diagonal shape with respect to the body unit 39. When the first blocking portion 301 and the second blocking portion 302 are formed in such a diagonal manner, the outlet 30a is naturally folded behind the body portion 39 as shown in FIG. 3F.

At this time, when forcibly moving the outlet 30a in front of the body portion 39 as shown in FIG. 3f, a restoring force is generated such that the outlet 30a goes back as shown by the arrow of FIG. 3f. However, since the body portion 39 supports such restoring force, the first blocking portion 301 and the second blocking portion 302 are kept unfolded without being folded. Therefore, when coupled to the container in the form of Figure 3f the body portion 39 is to maintain the form without loosening.

Figure 4a is a perspective view of a disposable straw according to a third embodiment of the present invention, Figure 4b is an illustration of the use of a disposable straw according to a third embodiment of the present invention. 4A and 4B, a straw 40, an inlet 40b, an outlet 40a, a body portion 49, a blocking portion 401, and a pleat portion 404 are shown.

In this embodiment, the wrinkle portion 404 is formed in the body portion 49 adjacent to the outlet 40a, and relates to a straw for easy drinking of the beverage. In the present embodiment, it is characterized in that the blocking portion 401 is formed between the outlet port 40a and the pleats 404. Since the shape of the blocking unit 401 has already been sufficiently described in the first and second embodiments, detailed description thereof will be omitted. The blocking portion 401 should basically be formed in the body portion 49 corresponding to the exposed position when the straw 40 is inserted into the container. If it is such a position may be formed anywhere except the wrinkle portion 404, it is preferably located between the wrinkle portion 404 and the outlet (40a). This is because when the blocking portion 401 is folded in this position and the outlet 40a is placed in the upper portion of the container 400a, the blocking portion 401 is not easily released and maintains its shape as shown in FIG. 4B.

On the other hand, as shown in Figure 4b, when the first blocking portion 401 in the folded state, the restoring force is generated as described above, this restoring force is offset by placing the outlet 40a in the upper container 400a. However, when the restoring force is strong, the body 49 inserted into the container 200 is pushed out. Therefore, the means for preventing the body portion 49 inside the container 200 from being pushed out by the restoring force should be taken.

Figure 5a is a perspective view of a disposable straw according to a fourth embodiment of the present invention, Figure 5b is an illustration of the use of a disposable straw according to a fourth preferred embodiment of the present invention. 5A and 5B, the straw 50, the inlet 50b, the outlet 50a, the body part 59, the first blocking part 501, the second blocking part 502, and the fixing part 506 are shown. ), The first inclined portion 506b, the second inclined portion 506a, and the engaging portion 507 are shown.

The fixing part 506 is a part of the body part 59 and is located between the second blocking part 502 and the inlet port 50b. The fixing part 506 serves as a locking protrusion so that the body 59 inserted into the container 500 does not push out. In order to act as a locking protrusion, the diameter of the fixing part 506 should be larger than the diameter of the coupling part 507 formed in the container 500. Although the diameter of the fixing part 506 is larger, the body part 59 is a synthetic resin penetrated therein, so it is difficult for the fixing part 506 to be inserted into the container through the coupling part 507 of the container 500. There is no.

The fixed part 506 is comprised by the 1st inclination part 506b and the 2nd inclination part 506a. The first inclined portion 506a has a shape in which the diameter of the body portion 59 gradually increases in the inlet 50b direction from the inlet 50b direction, and the second inclined portion 506a in the inlet 50b direction from the outlet 50a direction. The diameter of the body portion 59 gradually increases. Therefore, the largest diameter point in the fixing part 506 is the point where the first inclined portion 506b and the second inclined portion 506a are coupled.

As shown in FIG. 5B, when the fixing part 506 is inserted into the container 500, the first blocking part 501 and the second blocking part 502 are folded and the outlet 50a is positioned above the container. In 50a, a restoring force is generated in a downward direction, and as a reaction thereto, a lifting force is generated in the body portion 59 in an upward direction. However, this lifting force is blocked by the fixing part 506 having a larger diameter than the coupling part 507, and the restoring force is blocked by the container upper part 500a, thus maintaining a stable state as shown in FIG. 5B. In addition, the second inclined portion 506a blocks the coupling portion 507 to prevent the liquid inside the container 500 from flowing out.

6A is a perspective view of a disposable straw according to a fifth preferred embodiment of the present invention, and FIG. 6B is a diagram illustrating the use of a disposable straw according to a fifth preferred embodiment of the present invention. 6A and 6B, the straw 60, the inlet 60b, the outlet 60a, the body portion 69, the first blocking portion 601, the second blocking portion 602, and the fixing portion 606. ), A first inclined portion 606a, a second inclined portion 606b, a coupling groove 606c, and a coupling portion 607 are shown.

The present embodiment is characterized in that the coupling groove 606c is additionally formed in the fixing portion 606. Coupling groove 606c is almost the same as the diameter of the coupling portion 607 so as to facilitate fitting. On the other hand, when the diameter of the coupling groove 606c is formed smaller than the maximum diameter of the fixing portion 606 serves to more stably fix the body portion 69 to the container 600 after coupling as shown in Figure 6b.

7 is a flowchart illustrating a method of using a disposable straw according to a sixth exemplary embodiment of the present invention. This embodiment will be described with reference to FIGS. 3A and 3B. As shown in FIG. 3A, the straight straw 30 has inlets 30b and outlets 30a formed at both ends of the tubular body 39, and includes a first blocking part 301 and a second blocking part. 302 are formed in the body part 39, respectively.

S71 is a step of coupling the straw 30 to the container 200 in the direction of the inlet 30b. In order to drink the contents (beverage) inside the container 200, the straw 30 must be inserted. This step is a conventional step.

S72 is a step of folding the first blocking unit 301 and the second blocking unit 302 to prevent the contents from moving into the straw 30 into the body 39. When the first blocking part 301 and the second blocking part 302 are folded, a shape as shown in FIG. 3B is obtained. As shown in the enlarged view, the inner wall of the body portion 39 comes into contact with each other, preventing the contents from moving. Therefore, even if pressure is applied to the container 200, the contents do not flow out through the body portion 39.

S73 is a step of placing the outlet 30a in the container upper portion 200a so that the first blocking portion 301 and the second blocking portion 302 are not loosened. "Unlocked" means the case that the material of the body portion 39 of the straw 30 is a synthetic resin, the internal space of the body portion 39 is opened by the restoring force. That is, as shown in FIG. 3B, the restoring force is generated in the direction of the arrow in the outlet 30a, and the body portion 39 tries to maintain the straight shape again. In order to prevent this, the outlet 30a is positioned in the upper portion of the container 200a. The container upper portion 200a cancels this restoring force.

However, when the restoring force is strong, since the body portion 39 inside the container 200 may come out of the container 200, the fixing part 506 may be additionally formed in the body portion 59 as shown in FIG. 5B. 5B, the fixing of the body portion 39 to the container 500 by using the fixing portion 506 is preferably performed before the step S73.

8 is a flowchart illustrating a method of using a disposable straw according to a seventh preferred embodiment of the present invention. This embodiment will be described with reference to FIGS. 4A and 4B. As shown in FIG. 4A, the straw 40 has inlets 40a and outlets 40b formed at both ends of the tubular body portion 49, and a wrinkle portion 404 is formed. A blocking portion 401 is formed between the pleats 404 and the outlet 40b.

S81 is a step of coupling the straw 40 to the container 400 in the direction of the inlet 40b. In order to drink the contents (beverage) inside the container 400, the body 49 of the straw 40 must be inserted. This step is a conventional step.

S82 is a step of blocking the internal space of the body portion 49 by folding the blocking portion 401. Since the shape and operation principle of the blocking unit 401 have already been sufficiently described in the embodiments of FIGS. 4A and 4B, detailed descriptions thereof will be omitted.

S83 is a step of placing the outlet 40a formed on the body portion so that the blocking portion 401 is not released. This is a step for maintaining the internal space of the body portion 49 in a blocked state.

This embodiment is generally the same as the sixth embodiment of FIG. 7, except that the use of the straw 40 in which the pleated portion 404 and one blocking portion 401 are formed is used.

Although the technical spirit of the present invention has been described in detail according to the above-described embodiments, the above-described embodiments are for the purpose of description and not of limitation, and a person of ordinary skill in the art will appreciate It will be understood that various embodiments are possible within the scope.

As in the above embodiment, even if the disposable straw of the present invention is plugged into the container by the fixing portion does not fall easily. In particular, the coupling groove formed in the fixing portion increases the coupling force with the container. In addition, the contents can be prevented from spilling after being inserted into the container. Therefore, after drinking only a part of the beverage in the container, even if the beverage is moved, the risk of spilling the contents disappears.
