Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to the structure of a pouring portion in a bottom pouring type liquid container. As a bottom pouring liquid container, a bottom pouring type magic bottle using a double-ended vacuum bottle with openings at the top and bottom, as shown in Utility Model Application Publication No. 59-148734, is known. .

BACKGROUND ART In these liquid containers, a content liquid pouring path is formed in the lower part of the container, and a valve is provided in the middle of this pouring path. This valve is opened and closed by operating an external lever to pour out and stop the contents.

Problems to be Solved by the Invention However, with this structure, the lever must be continuously operated in order to continue dispensing the liquid content. It was troublesome to keep pressing the lever, especially when pouring a large amount of hot water into a large teapot or the like. Also, depending on the structure of the lever, it is possible to use a structure that allows dispensing by pressing it once and stopping dispensing by pressing it again, but this does not work in a short time when trying to dispense a small amount of liquid. You have to press the button twice, which is also cumbersome to operate.

The present invention was developed in view of the above circumstances, and allows the content liquid to be poured out by slightly rotating the lever, and when the hand that rotates the lever is released, the lever returns to its original position and stops dispensing. It is also an object of the present invention to provide a structure of a spouting part that continues dispensing even when the user's hand is removed by rotating the lever by a large amount.

Means for Solving the Problems The present invention provides a lower pouring type liquid container in which a valve for opening and closing a content liquid pouring passage is operated by rotating a rotary lever. A cam for slidingly operating the valve is formed on the rotary lever, and a cam edge corresponding to the valve open state of the cam is positioned at the center of rotation of the rotary lever. It is characterized by being formed into a circular arc with the center at .

FIG. 1 shows a bottom-pour magic bottle as a liquid container of the present invention, in which a main body 1 is fixed to the upper part of a leg 2. A protrusion 3 is formed at the front lower part of the main body 1, and a spout 4 is formed at the lower part of the protrusion 3. A valve inside the protrusion 3 is opened and closed by operating a rotary lever 5 attached to the protrusion 3, and the liquid is poured out from the spout 4.

FIG. 2 is a central vertical sectional view of the main part of the main body 1. The exterior body of the main body 1 has a body 6 and a bottom body 7, and a double-ended vacuum bottle 8 is accommodated within the exterior body.

The double-ended double-ended vacuum bottle 8 is supported by the bottom body 7 via the closing body 9, and the lower mouth pipe 11 leading to the lower opening 10 is fitted with a spouting pipe 12 forming a content liquid spouting path. 13. The spouting pipe 12 is fixed to the bottom body 7, and the molding error of the double-ended double-ended vacuum bottle 8 is adjusted by the fitting depth of the lower-end pipe 11 to the packing 13.

A valve member 15 is connected to the distal end of the spouting pipe 12 via a packing 14. In this valve member 15, the spout 4 is formed in the lower part of a cylindrical valve body 16, and a valve rod 17 is slidably inserted into the valve body 16. A valve body 19 is attached to the inner end of the valve rod 17, and the valve body 19 is closed by contacting the valve seat 18 formed on the inner surface of the valve body 16, and a substantially hemispherical head 20 is formed at the outer end. The head 20 protrudes from the tip of the valve body 16. The valve rod 17 is always biased by a spring 21 in the direction in which the valve closes.

The rotating lever 5 has a rotating shaft extending from the sliding axis of the valve rod 17, and is formed with a cam 22 that rotates as the rotating lever 5 rotates. The cam 22 is formed with an arc-shaped cam edge 23 centered on the rotation center of the rotating lever 5, and when the cam edge 23 is in contact with the head 20 of the valve rod 17, the valve The rod 17 is biased in the valve opening direction.

Reference numeral 24 denotes a stopper that prevents the rotation lever 5 from rotating when not in use. A cover 25 covers the valve member 15 and forms the protrusion 3 of the main body 1.

Operation Figure 2 shows the valve in the closed state according to the present invention. In this state, the rotating lever 5 is rotating upward, and the cam 22 is in a position where the cam edge 23 does not come into contact with the head 20 of the valve rod 17.
7 is biased in the valve closing direction, that is, to the left in the figure, by the elasticity of the spring 21, and the valve body 19 abuts against the valve seat 18 of the valve body 16, closing the valve. Therefore, although the liquid inside the double-ended double-ended vacuum bottle 8 flows from the lower mouth pipe 11 to the valve position via the spout pipe 12, it does not flow out any further.

If the rotation lever 5 is operated and rotated to the left in the figure, the cam 22 will rotate as shown in FIG.
The end of the cam edge 23 presses the head 20 of the valve rod 17, causing the valve rod 17 to bias toward the right in the figure against the elasticity of the spring 21.

As a result, the valve body 19 separates from the valve seat 18 and the valve opens, and the liquid inside the double-ended vacuum bottle 8 is transferred to the lower-end pipe 1.
1 through the spout pipe 12 and is poured out from the spout 4.

In this state, when you release your hand that is rotating the rotating lever 5, the valve rod 17 is biased to the left in the figure due to the elasticity of the spring 21, and the rotating lever 5 is also pushed to the right by the head 20. The valve rotates and returns to the closed state as shown in FIG.

Therefore, by slightly rotating the rotating lever 5, a desired amount of the liquid can be poured out, and when the hand rotating the rotating lever 5 is released, the dispensing can be immediately stopped.

Further, when the rotary lever 5 is operated and rotated significantly, the cam edge 23 of the cam 22 comes into contact with the head 20 of the valve rod 17, as shown in FIG. Thereby, the liquid content can be poured out from the spout 4 in the same manner as described above.

Also, at this time, the rotation axis of the cam 22 is on the extension line of the sliding axis of the valve rod 17, and the cam edge 23 of the cam 22 is formed in an arc shape centered on the rotation center of the cam 22. , even if you let go of your hand to rotate the rotating lever 5, the elasticity of the spring 21 will cause the rotating lever 5 to move.
does not rotate.

Therefore, even when dispensing a large amount of liquid, there is no need to continue rotating the rotary lever 5 by hand, and dispensing can be continued even if the user releases the hand.
Moreover, if the rotating lever 5 is rotated upward again, the second
It is possible to return to the state shown in the figure and stop pouring out the content liquid.

Effects of the invention According to the invention, two types of pouring operations can be performed depending on the magnitude of the rotation angle of the rotation lever 5. That is, by rotating the rotating lever 5 a small amount, the rotating lever 5 can immediately return to its original position and stop dispensing as soon as the hand is released, which is suitable for dispensing a small amount of liquid. In addition, if the rotating lever 5 is rotated widely, the rotating lever 5 will not return even if you release your hand, and you can continue dispensing up to the desired amount. Dispensing can be stopped by rotating the lever 5 upward again, and is suitable for dispensing a large amount of liquid.

In addition, in the present invention, the dispensing operation differs depending on the rotation angle of the rotation lever 5, but an appropriate click mechanism is provided at the boundary between the rotation angles, and if you release your hand before the click, the dispensing operation will be performed immediately. Preferably, dispensing can be stopped and dispensing can continue even if the hand is released by overcoming the click.
