Hereinafter, the structure of the present invention will be described in detail with reference to the accompanying drawings.

First, as shown in Figure 2, the packaging container 10 is configured.

The packaging container 10 may be formed in various shapes without being limited to the shape shown in FIG.

Next, the straw 20 uses a conventional straw 20 as it is shown in Figs.

The straw 20 is formed of a soft synthetic resin material that can be easily bent, and more preferably, is made of a PE material that is harmless to the human body and does not break even when repeatedly bent.

In addition, the inner diameter (d1) of the straw 20 is 2.5 to 5mm in diameter, the outer diameter (d2) is preferably formed to have a diameter of 4 to 8mm.

It is preferable to form a dimension within the threshold value because it has a problem in function as a straw when it is formed in a dimension smaller than the threshold value, and in the case where the threshold value is exceeded, the cross-sectional area in which the fluid moves is widened and the sealing property is degraded. .

On the other hand, the coupling portion 30 is composed of a structure that can be coupled to the packaging container 10, in particular, there is a fixing hole 31 that can be fixedly coupled to the straw 20, the fixed Side of the hole 31 is composed of a coupling hole 32 that can be coupled to the end of the straw 20 is not inserted into the packaging container (10).

Here, the straw 20 to be coupled to the fixing hole 31 is preferably coupled to maintain the airtightness through processing such as heat welding or sealing material injection.

In addition, the coupling hole 32 formed in the coupling portion 30 has an open groove 32a in the other direction in which the fixing hole 31 is formed, and the end of the straw 20 can be detached and attached. It is configured to.

In particular, the size of the opening groove (32a) is preferably formed to be smaller than the size of the coupling hole 32 to increase the adhesion of the straw (20).

On the other hand, in the present invention, the use identification unit 40 is further provided.

The use confirmation identification means 40 forms a fixing bar (41) detachably coupled to the opening groove (32a) formed in the coupling hole 32 of the coupling portion 30, the fixing bar 41 A bar-shaped removal bar 42 is formed in the direction extending upwardly), so that the user can easily remove the identification means for confirmation 40 through the removal bar 42.

Looking at the effect of the straw valve of the present invention made of a structure as described above are as follows.

First, the straw valve 50 of the present invention is maintained before the end of the straw 20 is not inserted into the packaging container 10 is coupled to the coupling hole 32 of the coupling portion 30.

That is, one end of the straw 20 is located inside the packaging container 10 and the other end is coupled to the end of the straw 20 exposed to the coupling hole 32 of the coupling portion 30 in a state exposed to the outside have.

In particular, the straw 20 coupled as described above is to maintain a state in which a portion is bent.

Here, the conventional straw is configured in the form of a thin tube, in particular, because the thickness is very thin because the bent portion as shown in Figure 3 when bent as shown in FIG. It is sealed.

That is, as shown in FIGS. 4 to 6, the straw 20 is normally free to move fluid such as air or water when the bending does not occur, but when the amount of bending is increased as shown in FIG. 20) is fully folded and sealed.

In this phenomenon, the cross-sectional area of the inner pipe of the straw 20 becomes smaller within the allowable curvature, but when the allowable curvature is exceeded, the first end surface S1 of the straw 20 in the bending direction as shown in FIG. 7. The second end surface S2 is not bent gently but is bent in an angular state, and the second end surface S2 opposite to the second end surface S2 is bent and partially bent while being partially tensioned as shown in FIG. 6. This is because the bending is performed in an angled state, and in particular, it is made of soft synthetic polyethylene (PE), and the airtightness is maintained by the bent portions of the first and second end surfaces (S1, S2) to have airtightness. Will be.

This principle is the same as the principle to cut off part of the air hose pipe as a temporary measure to cut off the air if the connection is not perfect during the work of the air hose pipe work in the field where the equipment equipped with the pneumatic system including the air hose is produced. Do.

However, in the present invention, since the size and thickness in the tube are thinner than the tube used for pneumatic pressure, the contents inside the packaging container 10 will have a sealability such that the contents do not leak to the outside.

On the other hand, in the combined state as described above, the user using the identification bar 40 using the removal bar 42 of the identification means for confirmation 40 to drink the contents in the straw valve 50 of the present invention. After the removal, if the end of the straw 20 which is coupled to the coupling hole 32 of the coupling portion 30 is moved in the direction in which the opening groove 32a is formed, the bent portion of the straw 20 is unfolded. The packaging container 10 is switched to a state in which the contents of the drink.

On the other hand, if the remaining amount is left without drinking all the contents inside the packaging container 10, if the end of the straw 20 exposed to the outside is attached to the coupling hole 32 of the coupling portion 30, again A portion of the straw 20 is bent so that the contents of the inside of the packaging container 10 do not come out of the bent portion serves as a valve, so that the portable after drinking.

[Example 1]

PE compressor with 2.5mm inner diameter and 4mm outer diameter (manufacturer: Hanyang Chemical Co., Ltd.). Compressor was connected to one side of the straw, and the other side was bent and placed in a fishbowl to check whether air leaked from the other side. Was sequentially inflated for 5 times at a pressure of 1 ~ 7bar.

[Example 3]

A PE straw (manufacturer: Hanyang Chemical Co., Ltd.) with an inner diameter of 5 mm and an outer diameter of 8 mm was connected to one side of the straw, and the other side was bent and placed in a fishbowl with a part bent to check whether air leaked from the other side. Air pressure was injected sequentially for 5 times at a pressure of 1-7 bar.

As in Examples 1 to 3, in the case of a straw having an inner diameter of 2.5 mm and an outer diameter of 4 mm, air did not leak when air was injected at a pressure of at least 6 bar, and air began to leak from 7 bar.

In particular, it can be seen that the larger the size of the cross-sectional area (inner diameter size) through which a fluid such as air or water moves, the thicker the thickness between the inner diameter and the outer diameter is, the more air leaks occur.

This, the result can be seen that the contents do not flow to the outside unless the pressure generated in the contents contained in the packaging 10 exceeds 6bar.

As described above, the present invention can reduce the material cost by using the straw 20 as it is conventionally used, and can be easily carried after drinking the contents of the inside of the packaging container 10 using a simple principle. It is to be able to achieve the object of the present invention.

Although the above-described embodiments have been described with respect to the most preferred embodiments of the present invention, the present invention is not limited thereto and may be modified in various forms without departing from the technical spirit of the present invention. It should be obvious to those skilled in the art.
