Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a liquid pouring cap that is excellent in preventing liquid leakage.

(Prior Art) Conventionally, as shown in FIGS. 6 and 7, a cap for dispensing a liquid includes an inner stopper 53 fitted into the opening 52 of a container 51, and a structure surrounding the inner stopper 53. Some devices include an outer lid 54 that is removably screwed onto the mouth portion 52. The inner stopper 53 has a conical inner pillar 55 in the center and a trough 57 around which a communication hole 56 is formed. On the other hand, the outer lid 54 has an upper wall 59 with a spout 58 in the center, an outer wall 61 with a female thread 60 that screws into the opening 52, and a trough 57 of the inner stopper 53 that fits tightly into the upper wall 59. It has an integral inner wall 62. A cap having such a structure is disclosed in, for example, Japanese Utility Model Publication No. 17670/1983.

When the outer lid 54 of the cap is rotated clockwise relative to the opening 52, the inner wall 62 fits into the trough 57 of the inner stopper 53 and the flow hole 55 is opened.
6 is closed, and the upper end of the middle column 55 closes the spout 58 of the outer lid 54 to prevent the fluid in the container 51 from flowing out. On the other hand, when the outer cover 54 is rotated counterclockwise with respect to the opening 52, as shown in FIG.
6 and the spout 58 are opened, and the trough 57 and the inner wall 62 are opened.
A gap is created between the container 51 and the container 51, allowing the fluid in the container 51 to flow out from the spout 58.

However, with the cap having the above structure, the cap must be rotated multiple times in order to obtain an appropriate amount of liquid to be poured out, which is inconvenient.

On the other hand, as shown in FIG.

-Disclosed in Publication No. 8191.

In this cap, the flow port 75 and the spout 76 are communicated with each other by a slight rotation of the outer lid 74, so that an appropriate amount of liquid can be poured out.

(Problem to be Solved by the Invention) However, since the communication hole 75 is only closed by the inner surface of the outer lid 74, if the container 71 is tilted in the closed state and the liquid level is above the communication hole 75. There was a problem in that the liquid inside the container 71 leaked out through a small gap between the outer surface of the inner stopper 73 and the inner surface of the outer lid 74.

This invention was created in view of these problems.
To provide a cap for a liquid container which allows liquid in the container to be poured out and sealed by a slight rotational operation, and which prevents liquid from leaking when the container is sealed.
