The present invention relates to a container for storing various liquids such as water, oil, liquid detergent, and more particularly, to a discharge structure of a liquid storage container in which the liquid is easily discharged without leaking when the liquid is poured. In the conventional liquid container 1, for example, as shown in FIG. 1, the lid 3 is detachably covered on the upper part of the body 2 in which the liquid 7 is housed. Is formed with a liquid discharge port 4. A handle 5 is formed at one side of the body 2, and a cover 6 is provided at the liquid discharge port 4. However, in the conventional liquid storage container configured as described above, a relatively small liquid discharge port 4 is formed in comparison with the body 2 in which the liquid 7 is accommodated, thereby discharging the liquid 7. In this case, air is introduced into the body through the outlet at the same time as the liquid is discharged through the outlet. At this time, due to the pressure change inside the body 2, the liquid is fluttering, and thus there is a problem that the liquid does not splash out or discharge smoothly.

Conventional prior art disclosed to solve such a problem is that of Japanese Unexamined Utility Model Publication No. 57-177946. The prior art has a structure in which a separate air distribution port is formed on a portion of the liquid outlet, but occupies a portion of the liquid outlet so that a large amount of liquid can not be discharged, and the size of the outlet must be relatively large. There is a disadvantage, because the air distribution part is in direct contact with the liquid outlet, leakage occurs after pouring the liquid, and if the flow velocity of the liquid is large, orifice phenomenon occurs around the air passage, and the outflowing fluid is reversed. There is a drawback that the backflow is sucked into the passageway, the air does not pass well, and the liquid is squirming, so the effect is hardly expected. In addition, the formation of an air flow path that occupies a portion of the cross-sectional area within the liquid outlet cross-sectional area is another technique that is quite difficult in manufacturing, which is almost impossible.

The present invention has been made in view of the above-described problems, and when the liquid is poured, the liquid is smoothly discharged without swelling, and is easy to manufacture and attach, and provides a discharge structure of a container in which no leakage occurs when the liquid is poured. Has its purpose.

The main configuration of the present invention for achieving the above object, in the known liquid storage container having an inlet 13 protruding to the upper surface, the liquid outlet 21 formed in the inner diameter of the inlet 13, The contact surface 22e is formed integrally with the bottom surface of the liquid discharge port 21 and is integrally attached to the bottom surface 12a of the upper surface of the container, and is formed between the contact surface 22e and the upper surface 12a of the upper surface of the container. An intermediate member 20 having a communication groove configured to communicate with a space formed between the outer circumference of the liquid discharge port 21 and the inlet 13 is characterized in that it is installed on the upper bottom surface 12a of the container.

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

2 is a side cross-sectional view showing an example in which an embodiment of the present invention is applied to a lid of a liquid storage container, and is a view in which the longitudinal direction of the communication groove 22 shown in FIG. 3 is extended and cut in a straight line. 3 is a partially cutaway perspective view showing an extract of the intermediate member shown in FIG. 2, and FIG. 4 is a side cross-sectional view showing a state of use of FIG.

According to an embodiment of the present invention, when the lid 12 is detachably covered, for example, as shown in FIG. 2, on the upper portion of the body 11 in which the liquid 7 is stored therein, the lid ( The intermediate member 20 is attached to the bottom face 12a of 12).

As shown in FIG. 3, the intermediate member 20 has a contact surface 22e mounted in contact with the bottom surface 12a of the lid 12, and a communication groove 22 formed with a lower groove than the contact surface 22e. To form. In addition, a liquid discharge port 21 having a diameter smaller than the inlet 13 of the container is formed at one side extending from the communication groove 22, and a concave annular groove 22d is formed at the lower end of the liquid discharge port 21. The communication groove 22 is formed to have a length in the horizontal direction to have the same lower height as the annular groove 22d of the lower end of the liquid discharge port 21.

Then, as shown in FIG. 2, the communication groove 22, the annular groove 22d, and the inlet 13 formed in the outer space of the liquid discharge port 21 are formed to be in air communication with each other.

On the other hand, the entire contact surface 22e of the intermediate member 20 except for the communication groove 22 and the annular groove 22d forming portion is attached, fastened, or integrally attached to the bottom surface 12a of the lid 12 over a large area. Is formed. That is, the intermediate member 20 formed on the bottom surface of the lid 12 is installed in a state of blocking the air inlet 13 and the body 11 inside. A use example according to the present invention configured as described above will be described with reference to FIG.

As illustrated, when the body 11 is inclined while the cover 14 is opened and the handle 15 is held by hand, the liquid outlet formed in the intermediate member 20 is formed with the liquid 7 contained in the body 11. It is discharged through 21.

At this time, the air inlet 13 formed as a space on the outer circumference of the liquid discharge port 21 communicates with the annular groove 22d, the communication groove 22 and the space inside the body 11, the air inlet 13 is atmospheric Since it is exposed to, the air flows into the body 11 through the air inlet 13 and the communication groove 22, so that atmospheric pressure acts constantly on the liquid contained in the body 11, as in the prior art. When pouring the liquid, the pressure changes inside the body will prevent the liquid from swelling. Accordingly, the liquid can be discharged smoothly without splashing.

FIG. 5A is another side view of the embodiment of FIG. 2, which is a partial side cross-sectional view taken in a straight line in the central longitudinal direction of the communication groove 22a in the same manner as in the embodiment of FIG. 5B is a view taken in the direction B-B of FIG. 5B, and FIG. 5B is a view showing that the communication groove 22a is formed between the lid 12 and the intermediate member 20. Partial cross section taken along line A-A.

The difference from the foregoing configuration here is that the communication groove 22a is not formed in the contact surface 22e of the intermediate member 20 but is formed in the bottom surface of the lid 12. In this case, the contact surface 22e of the intermediate member has a flat plate shape with no grooves such as the communication groove 22 and the annular groove 22d. However, the configuration of the liquid discharge port 21 is the same as in the previous embodiment.

The discharge structure according to the present embodiment also brings the same effect as the previous embodiment.

FIG. 6 is a cross-sectional view of a main portion showing another embodiment of the present invention, and is cut in the same direction as the previous embodiments, and FIG. 7 is a top view taken along the line c-c of FIG.

In the present embodiment, unlike the previous embodiments, communication grooves are not formed in the intermediate member 20 or the lid 12, but the side wall 22f is formed on the outer circumference of the intermediate member 20 to increase the predetermined height. By having it, the space 22b was formed between the bottom surfaces of the lid 12. In this case, as shown in Figure 7, the intermediate member is made in the shape of a double lid to cover the entire cross section of the container. In addition, at least one air hole 22c was formed at a position opposed to the liquid discharge port 21.

Since the air hole 22c and the space 22b communicate with each other, the air that enters through the air inlet 13 acts as an air passage and flows into the body 11.

In this structure, the outer circumferential surface of the intermediate member 20 is configured to be properly fitted to the inner circumferential surface of the lid 12 in order to facilitate assembly and disassembly.

As described above, the liquid storage container according to the present invention, when the liquid is discharged through the liquid outlet, the air entering through the air inlet formed in the lid through the air passage formed between the lid and the intermediate member inside the body Atmospheric pressure is applied to the liquid contained in the body inside the body, so that when the liquid is poured as in the prior art, the liquid does not swell due to the pressure change inside the accommodating portion, and thus the liquid does not splash and discharges smoothly. Have

In addition, according to the present invention, it can be manufactured as a single component, if necessary, can be freely detachable, there is an advantage that the liquid outlet 21 can also be selectively used to make various types, such as a jagged shape.

In addition, according to the present invention, when the liquid is poured, some leakage is recovered to the inlet 13 has an effect that the outlet is clean.

In addition, according to the present invention, a passage through which the air flows freely with the atmosphere is formed around the liquid discharge port 21, so that no backflow occurs in which a part of the liquid is curled, and no fluctuations in which the liquid fluctuates due to the sudden inflow of the air or the inflow of the irregular air are caused. Excellent effect.

In addition, according to the present invention, the accommodated liquid can prevent the liquid from jumping out of the outlet due to the slack during transportation of the container due to the space formed between the intermediate member and the lid and prevents the liquid from leaking out. It has the advantage of having an effect.
