Hereinafter, the present application will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, a cap A for a liquid container 100 according to the present application comprises an upper body 10; A lower body 20; And a cover (30).

The upper body 10 includes a discharge port 11 and an air inlet 12.

Therefore, the liquid content 100 accommodated in the container B to which the cap A for the liquid content-containing packaging container according to the present application is coupled can be discharged to the outside through the discharge port 11, and the air inlet 12 Outside air can be introduced into the container B. [

At this time, the discharge port 11 may include a first guide portion 11a (the opening width of the upper end is formed larger than the opening width of the lower end) protruding upward from the upper surface of the upper body 10.

Therefore, after the liquid content 100 is discharged, the liquid content 100 remaining around the discharge port 11 flows downward along the inner surface of the first guide part 11a and is reintroduced into the container B And liquid condensation can be prevented. Therefore, when the lid 30 is opened, the surrounding of the liquid content 100 remaining around the discharge port 11 can be prevented from being contaminated.

Here, the protrusion length of the first guide portion 11a may be longer than the protrusion length of the air inlet 12.

The air inlet 12 may protrude upward from the upper surface of the upper body 10. The air inlet 12 may protrude downward from the upper surface of the upper body 10. Specifically, the lower protrusion length of the air inlet 12 may be formed without limitation, but may be shorter than the lower length of the upper body 10, or may be formed to have the same length as the annular protrusion 15 described below. Further, the position of the air inlet 12 may be disposed inside the annular protrusion 15 described below.

In addition, the upper body 10 may include an annular protrusion 15 at the lower portion of the upper surface thereof.

The outer surface of the annular protrusion 15 is in close contact with the inner surface of the second guide portion 27 of the lower body 20 described below so that the coupling between the upper body 10 and the lower body 20 is securely And it is possible to prevent leakage of the liquid content 100 during use of the container (B).

The lower body 20 includes a cut-out portion 21 which is coupled with the upper body 10 and has a diameter larger than that of the discharge port 11.

Therefore, as the cut-out portion 21 is maintained in an uncut state, the container B can be sealed so that leakage of the liquid content 100 and external air contact can be blocked. Further, when the cut-out portion 21 is cut, the cut-out hole 22 is formed, so that a large amount of the liquid contents 100 can be discharged easily.

At this time, the cut-out portion 21 is formed to have a thin thickness, that is, in a groove shape, compared with other portions, so that it can be easily cut as an external force is applied.

Further, the cut-out hole 22 may be formed inside the extension line of the annular protrusion 15 of the upper body 10. Accordingly, the liquid content 100 discharged through the cut-out hole 22 can smoothly flow to the discharge port 11 by the guide of the annular protrusion 15. [

On the other hand, the upper and lower extension lines of the air inlet 12 may be located on the outer side of the cut-out hole 22 from the upper surface of the lower body 20. Therefore, the outflow of the liquid content 100 through the air inlet 12 can be prevented when the liquid content 100 is discharged.

In addition, the lower body 20 may include a grip ring 23 connected to the cut-out portion 21.

Therefore, as shown in FIG. 8, when the cutout portion 21 is cut, the grip ring 23 can be pulled and cut easily.

In addition, the lower body 20 may include a second guide portion 27 at an upper portion thereof. 2 and 9, the second guide portion 27 is a portion that can be fitted between the inner surface of the upper body 10 and the outer surface of the annular protrusion 15.

Accordingly, the liquid content 100 remaining in the lower body 20 flows downward along the inner surface of the second guide portion 27 after the liquid content 100 is discharged through the cut-off hole 22, It is re-introduced into the container (B), so that liquid condensation can be prevented.

In addition, the second guide portion 27 may have a groove 27a formed thereon. 9, the cross-sectional shape of the groove 27a has a shape recessed by a predetermined depth in an inner diameter direction on the outer circumferential surface of the second guide portion 27, and the groove 27a has a cross- And may be formed over the outer circumferential surface of the portion (27). On the other hand, the specific cross-sectional shape of the groove 27a is not only depressed by a predetermined depth in the inner diameter direction of the second guide portion 27, but also extends in the upward direction of the second guide portion 27 by a predetermined length And the like.

As the groove 27a having such a shape is provided, the upper end of the second guide portion 27 may take the form of a ring. That is, as shown in FIG. 9, the second guide portion 27 may be provided at the upper end of the second guide portion 27 with a tight fitting portion 27b having an annular shape bent in the outer diameter direction. Therefore, when the lower body 20 is coupled with the upper body 10, the close contact portion 27b provided at the upper end of the second guide portion 27 can be closely contacted with the inner peripheral surface of the upper body 10 have. Thus, leakage of the liquid content 100 through the joint between the lower body 20 and the upper body 10 can be prevented. The second guide portion 27 is provided at the upper end of the second guide portion 27 with an annular contact portion 27b so as to be brought into close contact with the inner circumferential surface of the upper body 10 so that even when the liquid content of the liquid content 100 is large The leakage of the liquid content 100 can be effectively prevented.

In addition, the lower body 20 may have a trough 24 spaced from the inner circumferential surface on the inner side of the lower portion.

Therefore, the upper body of the container B is inserted between the inner circumferential surface of the lower body 20 and the tip 24, so that the combined state of the lower body 20 and the container B can be secured.

A protrusion 25 may be formed at the lower end of the inner surface of the lower body 20.

Therefore, as the protruding jaw 25 is brought into close contact with the outer circumferential surface of the container B, the combined state of the lower body 20 and the container B can be further strengthened.

At this time, the projecting step 25 may be coupled to the concave-convex portion formed on the outer peripheral surface of the container B. Therefore, the airtightness between the lower body 20 and the container B can be maintained smoothly.

The lid 30 is connected to the upper body 10 and is fitted on the upper body 10 to block exposure of the upper surface of the upper body 10. [

Therefore, foreign matter can be prevented from flowing through the discharge port (11) and the air inlet (12) by coupling the cover (30) to the upper body (10).

In addition, the lid 30 may include a first blocking portion 32 for blocking the opening of the discharge port 11. [

Accordingly, unintentional outflow of the liquid content 100 through the discharge port 11 can be prevented as the first cut-off portion 32 blocks the opening of the discharge port 11.

At this time, the tip end of the first blocking portion 32 is inserted into the discharge port 11.

Therefore, the opening of the discharge port 11 can be stably shut off as the outer circumference of the first blocking portion 32 is close to the inner surface of the discharge port 11.

In addition, the lid 30 may include a second blocking portion 33 for blocking the opening of the air inlet 12.

Accordingly, unintentional outflow of the liquid content 100 through the air inlet 12 can be prevented as the second cut-off portion 33 blocks the opening of the air inlet 12.

The tip end of the second blocking portion 33 is inserted into the air inlet 12.

Accordingly, the opening of the air inlet 12 can be stably shut off as the outer circumference of the second cut-off portion 33 comes close to the inner surface of the air inlet 12.

In addition, the first blocking portion 32 may include a first rib 32a formed radially inward.

Therefore, by supporting the first rib 32a, the first blocking portion 32 becomes more rigid, thereby preventing the first blocking portion 32 from being damaged.

In addition, the second blocking portion 33 may include a second rib 33a formed radially around the outer surface of the upper portion.

Therefore, by supporting the second ribs 33a, the second blocking portions 33 are made more rigid so that damage to the second blocking portions 33 can be prevented.

Meanwhile, the upper body 10 and the lower body 20 can be coupled by the helical engagement. A spiral 13 may be formed on the inner circumferential surface of the lower portion of the upper body 10 and a spiral 26 may be formed on the outer circumferential surface of the upper portion of the lower body 20.

Therefore, the upper body 10 and the lower body 20 can be simply coupled with each other by binding the spiral 13 of the upper body 10 and the spiral 26 of the lower body 20, The engagement between the spiral 13 of the upper body 10 and the spiral 26 of the lower body 20 is released so that the upper body 10 and the lower body 20 can be separated easily.

The upper body 10 and the lid 30 may be connected to each other by a connection ring 31. The connection ring 31 is formed closer to the air inlet 12 than the discharge port 11 so that interference by the lid 30 is minimized when the liquid content 100 is discharged through the discharge port 11 .

The use of the cap A for the liquid contents-containing container according to the present application will be described in detail as follows.

3, when the cap A for a liquid containing contents packaging container according to the present application is initially engaged with the container B, the cutout 21 of the lower body 20 is not cut off Whereby the container (B) is sealed.

Therefore, even if the container B flows during a circulation process or the like, unintentional outflow of the liquid content 100 contained therein is prevented, and outside air contact is prevented.

In the meantime, in the cap A for the liquid contents-containing container according to the present application, the cut-out portion 21 of the lower body 20 is cut off before use. Therefore, the liquid content 100 in the container B is introduced into the upper body 10 through the cut-off hole 22 formed as the cut-out portion 21 is cut, as shown in FIG. Can be discharged through the discharge port (11).

At this time, the upper body 10 is formed with the air inlet 12 together with the discharge port 11, so that the liquid content (hereinafter referred to as " liquid content " 100) can be smoothly discharged through the discharge port (11).

In addition, in the present application, the discharge port 11 may include the first guide part 11a on the upper part. Therefore, after the liquid content 100 is discharged, the liquid content 100 remaining around the discharge port 11 flows downward along the inner surface of the first guide part 11a and is reintroduced into the container B . Therefore, liquid condensation of the liquid content 100 can be prevented, so that contamination of the periphery or the like due to leakage of the liquid content 100 remaining around the discharge port 11 when the lid 30 is opened is prevented .

However, since the discharge port 11 is formed to have a relatively small diameter, it is suitable for small-amount discharge of the liquid-containing substance 100, so that it may be difficult to discharge a large amount of the liquid.

However, in the present application, the upper body 10 and the lower body 20 are coupled only by the helical binding, and the upper body 10 can be separated from the lower body 20 when the threading is released. Accordingly, when the upper body 10 is detached, the liquid content 100 is discharged to the outside of the container B directly through the cut-out hole 22 as shown in FIG.

The diameter of the cut-out portion 21 is formed to be larger than the diameter of the discharge port 11 so that the cut-out hole 22 formed by cutting the cut-out portion 21 has a diameter larger than the diameter of the discharge port 11 The liquid content 100 can be ejected in a relatively large amount as the liquid content 100 is directly discharged through the cut-out hole 22.

Here, the lower body 20 may include the second guide portion 27 on the upper portion thereof. Accordingly, the liquid content 100 remaining in the lower body 20 flows downward along the inner surface of the second guide portion 27 after the liquid content 100 is discharged through the cut-off hole 22, It is re-introduced into the container (B), so that liquid condensation can be prevented.

However, since there is no separate air inlet means such as the air inlet 12 of the upper body 10 in the lower body 20, the liquid contents 100 may leak into the lower body 20 through the cut- have.

However, since the cut-off hole 22 has a relatively large diameter, air can be introduced simultaneously with the discharge of the liquid content 100 (see a thick arrow in FIG. 5). Therefore, even if there is no separate air inflow means, the liquid content 100 can be smoothly discharged without being clogged.

Meanwhile, foreign matter may be introduced into the upper body 10 through the discharge port 11 and the air inlet 12.

However, in the present application, the lid 30 is connected to the upper body 10 coupled to the lower body 20, and the lid 30 covers the upper body 10, And the opening of the air inlet 12 can be blocked. More specifically, as shown in FIG. 6, the first blocking portion 32 is inserted into the discharge port 11, and the second blocking portion 33 is inserted into the air inlet 12, as shown in FIG. The foreign matter can be prevented from flowing through the discharge port 11 and the air inlet 12 of the upper body 10 because the opening of the discharge port 11 and the air inlet 12 is blocked, have.

However, when the first blocking portion 32 and the second blocking portion 33 are damaged or broken, it may be difficult to block the opening of the discharge port 11 and the air inlet 12.

However, in the present application, the first blocking portion 32 may include the first rib 32a formed radially inward, and the second blocking portion 33 may be formed radially around the outer surface of the upper portion And may include a second rib 33a. Therefore, the first blocking portion 32 and the second blocking portion 33 are further strengthened by the support of the first and

second ribs

32a and 33a, 2 blocking portion 33 can be prevented from being damaged.

As described above, since the cap (A) for the liquid contents-containing packaging container according to the present application is circulated in a state in which the lower body (20) is hermetically sealed, leakage of the liquid content (100) have. The discharge port 11 is formed in the upper body 10 and the cutout portion 21 having a diameter larger than that of the discharge port 11 is formed in the lower body 20, The liquid content 100 is discharged from the lower body 20 through the discharge port 11 of the upper body 10 while the cut portion 21 of the upper body 20 is cut off, 10, and discharging the liquid content 100 through the cut-out hole 22, the discharge amount of the liquid content 100 can be easily adjusted.

The cap A for a liquid contents packaging container according to the present application is characterized in that a groove 27a is formed on the upper portion of the second guide portion 27 of the lower body 20, And a tight fitting portion 27b having an annular shape bent in the outer diameter direction of the second guide portion 27 may be provided at the upper end portion. Therefore, when the lower body 20 is coupled with the upper body 10, the close contact portion 27b provided at the upper end of the second guide portion 27 is in close contact with the inner peripheral surface of the upper body 10, The leakage of the liquid content 100 can be prevented. Particularly, even if the fluidity of the liquid content 100 is large (for example, soy sauce etc.), leakage of the liquid content 100 can be effectively prevented

As described above, the present application is not limited to the above-described embodiments, and thus can be modified without departing from the gist of the present invention as claimed in the claims, And is within the protection scope of the application.
