However, in the conventional containers shown in FIGS. 7 and 8, the spout hole 15 is not closed even when not in use, so there is a risk that the contents may leak out if the container falls over when not in use.

In addition, the conventional one shown in FIG. 9 has a lever 45.
The spout hole 15 can be opened and closed by swinging, but the spout hole 15
Since the lever 45 protrudes when the is closed, there is a risk that the spout hole 15 may easily open if the lever 45 touches another object.

This invention was made in view of the above matters,
A technical problem is to create a spouting cap that allows the spouting tube to be moved in and out of the cap with a simple operation, and also allows the spouting hole to be opened and closed, and furthermore, there is less risk of the spouting hole being accidentally opened. .

[Means for solving problems]

A holding cylinder 3 is provided on the main body 1 which is attached to the mouth and neck part 39 of the container, and a spouting cylinder 13 provided with a seal part 14 is slidably fitted into this holding cylinder 3. A plug 5 that can close the spout hole 15 of the spout tube 13
, a communication hole 6 is provided, a compression bar 22 is inserted between the bottom of the holding cylinder 3 and the lower part of the spouting cylinder 13 , and a spouting cylinder outlet 26 is provided in the upper part of the main body 1 . A provided outer cap 24 is rotatably fitted, a guide tube 25 is provided hanging down from the outer cap 24, and either one of the outside of the pouring tube 13 and the lower part of the guide tube 25 is attached. A spiral sloped surface 17 is formed on the other side, and contact surfaces 17 and 27 are provided on the other side of the spiral sloped surface 17 to push down the pouring tube 13, and,
A flat surface 18 was provided on at least one of the tip of one spiral inclined surface 17 and the tip of the other contact surfaces 17 and 27 to form a pouring cap.

[Effect]

In the present invention, when the outer cap 24 is rotated to a position where the spiral inclined surfaces 17, 17 of the pouring tube 13 and the guide tube 25 match, or to a position where the spiral inclined surface 17 and the protruding surface 27 match, the first As shown in the figure, pouring tube 1
3 is pushed up by the compression spring 22, and the spout barrel 1
3 protrudes from the spouting tube outlet 26, the spouting hole 15 is separated from the stopper 5, and the spouting hole 15 communicates with the inside of the container.

Next, when the outer cap 24 is rotated, the spiral inclined surface 17 comes into contact with the opposing contact surfaces 17, 27,
Spiral inclined surface 17 and opposing contact surfaces 17, 27
is subjected to a force perpendicular to the surface, but the pouring tube 13 contacts the holding tube 3 via the compression spring 22, and the frictional resistance is large, so it does not rotate, and as shown in FIG. is compressed and pushed down into the holding cylinder 3. Then, the outer cap 24 is rotated to a position where the tips of the spiral inclined surfaces 17, 17 of the spout tube 13 and the guide tube 25, or the tips of the spiral inclined surfaces 17 and the tip of the protruding surface 27 match. Since at least one of the tips is formed on the flat surface 18, the tip comes into contact with the flat surface 18 perpendicularly, and no force acts to rotate the guide tube 25. Therefore, even if the user releases the outer cap 24, the spout barrel 13 remains in the depressed position.

Next, when the outer cap 24 is rotated and the tip portion is removed from the flat surface 18, the spout cylinder 13, which is pressed by the compression spring 22, rises while rotating the guide cylinder 25.
