Description

Lid of a liquid container < RTI ID = 0.0 >

[0001] The present invention relates to a cap of a liquid storage container, more specifically, a cap housing of a transparent or semitransparent material coupled to a top opening of a conventional liquid storage container, Wherein the cap housing is provided with a discharge passage for discharging the contents out of the storage container and a quantity of contents proportional to the contents discharged through the discharge passage in real time A liquid storage container configured to discharge a predetermined amount while grasping the amount of the discharged amount of the contents in real time with reference to an indication of the contents stored in the discharge amount indication chamber when the contents are discharged by inclining the storage container It is about the lid.

Generally, liquid products such as soy sauce, cooking oil, liquid detergent, etc., which are mainly used at home, are stored in a storage container provided with an inlet at the upper end, and an appropriate amount of the contents is discharged whenever necessary. For this purpose, a measuring cup manufactured in a predetermined form may be used. However, in this case, the measuring cup must be stored along with the measuring cup, and the contents contained in the measuring cup must be removed at every use.

In order to solve this problem, a lid equipped with a discharge control means may be used. For example, Korean Patent No. 10-1151356 (May 23, 2012) and Laid-open Patent No. 10-2013-0086817 (August 05, 2013) disclose a method of discharging the contents stored in a liquid storage container by a predetermined amount The container lid that can be introduced is introduced. Such a conventional container lid has a disadvantage in that it is difficult for the user to arbitrarily adjust the amount of the discharged substance because the amount of the contents discharged in a single operation is predetermined.

In order to alleviate this inconvenience, International Patent Publication No. WO2006 / 049668 (May 11, 2006) and corresponding US Patent No. 7,845,524 (Dec. 07, 2010) disclose that the user can check the emission amount in real time, The lid of a liquid storage container is introduced. As shown in FIGS. 1 and 2, the lid of the liquid storage container is provided with a discharge chamber 30 and a display chamber 32 inside the lid, which are separated from each other by a partition wall 44.

The discharge chamber 30 has an inlet 30A and an outlet 26 through which the contents pass though the display chamber 32 has only an inlet 34 and no outlet. Thus, when the user tilts the storage container 12 to discharge the contents, the contents stored in the storage container 12 are introduced into the inner chamber 70 by the flow guide 76, And then discharged through the inlet 30A and the outlet 26 of the discharge chamber 30 and out of the storage vessel 12.

At the same time, a part of the contents is introduced into the display chamber 34 through the inlet 34 of the display chamber 34 as shown by an arrow in Fig. 2 and then is blocked by the opposite closed end 36, ). ≪ / RTI > The inlet 34 of the display chamber 34 is provided with a guide channel 62 for guiding the flow of contents. Thus, while the contents are being discharged through the discharge chamber 30, another portion of the contents continues to flow into the display chamber 34 and is stored.

At this time, the water level of contents stored in the display chamber 34 is proportional to the discharge amount of the contents discharged through the discharge chamber 30. Thus, the user can measure the discharge amount of the contents by observing the water level of the contents through the sight window 38 of the display chamber 34. [ In the viewing window 38, a scale (arrow) indicating the amount of the contents to be discharged is displayed.

Registration No. 10-1151356 (May 23, 2012) Open Patent No. 10-2013-0086817 (Aug. 05, 2013) WO2006 / 049668 (May 11, 2006) U.S. Patent No. 7,845,524 (Dec. 07, 2010)

The lid of the liquid storage container of FIGS. 1 and 2 has an advantage that the user can discharge the contents while confirming the discharge amount in real time through the display chamber 34. In order for the lid of the liquid storage container to sufficiently exhibit such a function, the contents introduced into the display chamber 32 when the storage container 12 is tilted are sequentially discharged from the closed end 36 of the display chamber 32 And the user must be able to easily observe the display amount of the display chamber 32 through the viewing window 38. [

However, in the case of the lid of the liquid storage container, when the user tilts the storage container 12 without any care, the contents pour into the display chamber 32 downward through the inlet 34, . There is a high possibility that bubbles or air bubbles may be generated by mixing the contents introduced through the inlet 34 and the air inside the display chamber 32. Such bubbles or bubbles may cause the user to accurately grasp the display amount of the display chamber 32 To prevent it. In particular, when the content is a colored liquid or a detergent which is easy to generate foam, such a concern becomes much more likely to cause the function of the lid of the liquid storage container to deteriorate.

Also, the amount of the contents discharged into the discharge chamber 30 must be proportional to the amount of the contents introduced into the display chamber 32 in real time. The contents introduced into the inlet 30A of the discharge chamber 30 are directly discharged to the opposite outlet 26. Since the display chamber 32 has no outlet, (32) should be vented out.

3, the lid of the liquid storage container includes a first member 46 including a display chamber 32, a second member 48 including a discharge chamber 30, And a third member 52 including a flow control device 54, a fluid handler 58, a flow guide 76, and the like. However, in this structure, when the liquid container 12 is raised again, the contents stored in the display chamber 32 can not be completely recovered into the liquid container 12, and some contents remain in the display chamber 32 In this case, an error may occur between the display amount of the display chamber 32 and the drain amount of the discharge chamber 30. In addition, the lid of the liquid storage container has a three-piece structure, and the overall structure is complicated and there is room for improvement in terms of the production efficiency in terms of structure.

Accordingly, it is an object of the present invention to improve the structure and function of the lid of the conventional liquid storage container shown in Figs. 1 to 3, And further to provide a lid of a liquid storage container in which the overall structure is simpler than the lid of a conventional liquid storage container, thereby improving the production efficiency.

Wherein the contents introduced into the discharge indication chamber are first introduced into the inlet of the first display chamber and then through the end fluid passage to be filled in the second display chamber, 1 display chamber is separated from the inlet of the display chamber.

The flow control unit may include a flow control plate provided inside the lower end of the cap housing and through which the outlet of the second display chamber passes, and a space formed between the flow control plate and the inner wall of the cap housing, An inclined flow channel for obliquely guiding the contents introduced into the discharge amount display chamber to an inlet of the first display chamber at a position adjacent to the discharge passage inlet; And a channel wall for blocking off between the outlets of the display chamber.

The liquid storage container lid according to the present invention is configured such that when the storage container is tilted at an appropriate angle to discharge the contents, the contents introduced into the discharge amount indication chamber are first introduced into the inlet of the first display chamber, And the air inside the discharge indication chamber is discharged to the inside of the storage container through the outlet of the second display chamber, so that the contents introduced into the discharge indication chamber and the air discharged from the discharge indication chamber Do not interfere with each other.

Therefore, there is no possibility that bubbles or bubbles are generated in the contents stored in the discharge amount display chamber, and the stable water level is maintained. Therefore, the user can grasp the display of the discharge amount display chamber more accurately and easily.

In addition, the lid of the liquid storage container according to the present invention has a two-piece structure of a cap housing and a flow path guide member, and the overall structure is simple, so that the production efficiency can be improved.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. The structure of the lid of the liquid storage container of the present invention is basically divided into upper and lower positions based on the state where the storage container provided with the lid is erected upright. However, in the present invention, the term 'discharge' or 'inflow' refers to a phenomenon in which when the storage container is tilted at an appropriate angle to discharge the contents of the storage container, the contents flow downward toward the lid by gravity. The term " recovery " of the contents refers to a phenomenon in which the contents remaining inside the lid flow back into the storage container when the contents are tilted and then upright again.

The cap of the liquid storage container according to the present invention includes a cap housing 10 coupled to an upper inlet of a conventional liquid storage container (not shown) as shown in FIGS. 4 to 6, And a flow path guide member 20 provided inside the flow path guide member 20. The liquid storage container to which the lid of the present invention is applied is not particularly limited. However, it is preferable that a handle is provided on one side of the liquid storage container in which the inlet is formed at the upper end.

First, the cap housing 10 is a cylindrical body made of a transparent or semitransparent synthetic resin material, and has a coupling portion 11 coupled to an inlet of the storage container at a lower end thereof. The engaging portion 11 is preferably a threaded portion formed on the inner diameter of the lower end of the cap housing 10. A discharge port 12 extends through the upper surface of the cap housing 10 opposite to the coupling portion 11 and a discharge cap 12a for opening and closing the discharge port 12 is provided adjacent to the discharge port 12.

6, 9 and 10, the internal space of the cap housing 10 is divided into a discharge passage 13 and a discharge amount indication chamber 14 on both sides. The discharge passage 13 serves to guide the contents of the storage container to the discharge port 12 and to discharge the contents out of the storage container. The amount of the content proportional to the content discharged through the discharge passage 13 flows into the discharge amount indication chamber 14 in real time. However, since the discharge indication chamber 14 is closed at its upper end by the end blocking wall 14c and the end blocking wall 14c faces downward when the storage container is tilted, The contents are stored as they are. A partition wall (15) is provided between the discharge passage (13) and the discharge amount display chamber (14).

Next, the flow path guide member 20 has a flow control unit 21 for controlling the flow path of the contents and a guide wall 22 inserted into the discharge amount display chamber 14. [ The flow control unit 21 functions to introduce a part of the contents into the discharge passage 13 and a part of the contents to the discharge amount indication chamber 14. [ 9, the guide wall 22 is inserted into the discharge amount indication chamber 14 so that the internal space of the discharge amount indication chamber 14 is communicated with the first display chamber 14a and the second display chamber 14b, As shown in FIG. The free end portion 22a of the guide wall 22 is spaced apart from the end wall 14c of the discharge amount indication chamber 14 by a predetermined distance so that the free end portion 22a is separated from the end wall 22c by a predetermined distance A distal fluid passage 23 through which the contents can pass is formed.

Therefore, when the storage container is inclined at an appropriate angle to discharge the contents, the contents are simultaneously introduced into the discharge passage 13 and the discharge amount indication chamber 14 by the flow passage control part 21. [ The contents introduced into the discharge passage 13 are discharged out of the storage container as it is through the discharge port 12 as indicated by the arrow in Fig. The contents introduced into the emission display chamber 14 are first introduced into the first display chamber 14a and then through the end fluid passage 23 to the second display chamber 14a, 14b).

The outlet 142 of the second display chamber 14b is connected to the interior of the storage container 14 separated from the inlet 141 of the first display chamber 14a as shown in FIG. Therefore, while the contents are introduced into the inlet 141 of the first display chamber 14a, the air inside the discharge amount indication chamber 14 does not interfere with the inflow of the contents, And is discharged into the interior of the storage container through the opening 142. 4 to 6, a reference numeral 221 is a 'support plate' for supporting the guide wall 22 to the partition wall 15. [

In the present invention, the discharge passage (13) is preferably disposed on the opposite side of the handle provided on one side of the storage container. The discharge passage 13 and the first display chamber 14a and the second display chamber 14b are arranged side by side in the longitudinal direction of the cap housing 10 and the first display chamber 14a And is preferably disposed between the discharge passage 13 and the second display chamber 14b. Thus, when the storage container is tilted by holding the handle, the discharge passage 13 is disposed at the lowest position, and the first display chamber 14a and the second display chamber 14b are sequentially disposed thereon desirable.

According to a preferred embodiment of the present invention, the flow path control section 21 has a flow path control plate 211 and a discharge path inlet 212, a sloping flow path channel 213, and a channel wall 214. The flow control plate 211 is installed on the coupling portion 11 inside the cap housing 10 and has an outlet 142 through which the second display chamber 14b is passed.

The inclined channel channel 213 is connected to the outlet 142 of the second display chamber 14b by the inclined channel channel 213 and the outlet 142 of the second display chamber 14b. The channel wall 214 is provided so as not to fall over.

The inclined flow channel 213 serves to introduce the contents flowing into the discharge passage 13 and the contents flowing into the discharge amount indication chamber 14 at the same level and at the same condition when the storage container is tilted. 4 and 8, the discharge passage inlet 212 is disposed on both sides of the lower end of the inclined flow channel 213 and between the discharge passage inlet 212 and the lower end of the inclined flow channel 213 A pair of flow path separating blades 24 protrude. The flow path separating vane 24 functions to guide the contents flowing into the discharge passage 13 and the contents flowing into the discharge amount indication chamber 14 smoothly without interfering with each other.

6 and 9, an outlet 142 of the second display chamber 14b is provided with a buffer chamber 25 for blocking the contents from flowing into the second display chamber 14b desirable. The outlet 251 of the buffer chamber 25 is connected to the interior of the storage container in a state separated from the inlet 141 of the first display chamber 14a. Therefore, when the storage container is tilted suddenly, even if unwanted contents are introduced into the outlet 251 of the buffer chamber 25, the contents do not flow into the second display chamber 14b due to the buffer chamber 25 .

It is preferable that a flow path blocking plate 26 is provided between the outlet 251 of the buffering chamber 25 and the upper end of the inclined flow channel 213 to block the contents from flowing into the buffering chamber 25 .
