[0002]
[Prior art and its problems]
As this type of double valve type liquid pouring tap, one disclosed in JP-A-8-295398 is known.
This spout was formed on the cylindrical wall by shifting the first through hole and the second through hole by 90 degrees to the plug body having a nozzle projecting and an opening on the container side and an air hole on the opposite side. The rotating cylinder is fitted in a rotatable manner, and the rotating cylinder is rotated 90 degrees from the state in which the air hole and the second through hole communicate with each other at the time of closing, and the opening on the container side and the first through hole are connected to the nozzle. The second through holes communicate with each other so that the liquid in the container can be poured out. When the rotating cylinder is rotated in the opposite direction and closed after pouring, the air hole and the second through hole communicate with each other so that the liquid staying in the rotating plug can be easily removed from the nozzle. Yes.
However, in this configuration, since three holes are formed in the plug body, there is a risk that liquid may be ejected from the air holes when the rotating cylinder is stopped at a halfway position. Therefore, there is an inconvenience that the liquid quantity cannot be selected with the pouring tap of this configuration.

[Technical issues]
The present invention provides a rotating stopper having a nozzle provided with a nozzle wall and a valve wall for opening and closing the liquid supply port, and a support plug provided with a nozzle and provided with a liquid supply port on the mounting side of the container. A double valve type liquid pouring tap that is fitted tightly and the turning plug is turned so that the valve wall opens the liquid supply port and the pouring hole communicates with the nozzle to pour out the liquid in the container. However, it is an object of the present invention to be able to select different liquid amounts with one touch.
[0004]
[Technical means]
The first technical means for solving this technical problem is as follows: (a) The rotary plug is tightly fitted so that it can be rotated in the forward and reverse directions from the closed position, and (b) in each rotational direction. That is, the pour hole having a different size is formed in the rotary stopper.
The second technical means is: (c) tightly fitting the rotary plug in the forward / reverse direction from the closed position, and (d) the two outlet holes on each rotary direction. And (e) the opening area of the liquid supply port by the valve wall when each discharge hole communicates with the nozzle is made different.
[0005]
In the first technical means, the rotary plug tightly fitted to the support plug can be rotated in the forward and reverse directions from the closed position, and the rotary plug has a rotational direction in the rotational direction. are formed pouring hole having different sizes, by selecting the rotational direction of Kaidosen, can be communicated to different sizes Note Deana the nozzle. Even if the same amount of liquid is supplied from the liquid supply port, the amount of liquid to be dispensed from the nozzle differs due to the size of the dispensing hole being different. Therefore, it is possible to select dispensing of different liquid amounts with one touch only by selecting the rotation direction of the rotary stopper.
[0006]
Also in the second technical means, the rotary plug tightly fitted to the support plug enables rotation in the forward and reverse directions from the closed position. The size of the two extraction holes formed in each rotation direction of the rotation line is not different, but the opening area of the liquid supply port by the valve wall when each extraction hole communicates with the nozzle is different. Therefore, the amount of liquid supplied from the liquid supply port to the spout is different. Therefore, the amount of liquid can be selected with a single operation simply by selecting the direction of rotation of the rotary stopper.
In this case, if the size of the two extraction holes is made to correspond to the opening area of the liquid supply port, the liquid can be supplied into the extraction plug corresponding to the amount of liquid discharged from the nozzle. Yes (see claim 3).
[0007]
In the pouring tap in the first to third technical means, the pouring hole is constituted by a long hole along the turning direction of the turning plug, and the valve of the turning plug is used when the opening state is changed to the closing state. If the discharge hole is closed by the cylindrical wall of the support plug after the wall closes the liquid supply port of the support plug, even if the supply from the container to the discharge plug is stopped during the closing, The dispensing hole communicates with the nozzle. Therefore, the liquid in the spout can be continuously poured out from the nozzle, and the liquid can be prevented from staying in the spout as much as possible.
[0008]
Even if some liquid stays in the rotary stopper when liquid is discharged from the nozzle using any one of the discharge holes, the liquid is leaked from the discharge hole because the side wall receives between the discharge holes. There is no fear of dispensing, and the liquid that has accumulated when the liquid is dispensed next time using any of the dispensing holes will be poured out. Therefore, the same liquid does not stay in the rotary stopper.
[0009]
[Effect of the present invention]
Since the amount of liquid can be selected with a single operation by selecting the direction of rotation of the swivel plug, it can be used for containers that receive dispensed liquid, and is large for large containers such as bottles and plastic bottles. There is an advantage that it can be filled quickly according to the amount of liquid, and a small container such as a cup can be slowly poured out with a small amount of liquid.
In addition, in the pouring tap of this configuration, the valve function is exhibited at two locations on the container side and the nozzle side when the cap is closed, and the valve on the container side receives the water pressure of the liquid and the valve on the nozzle side is released from the water pressure. As a result, a sufficient sealing effect can be exhibited as a whole of the spout.

When the rotary plug 12 is closely fitted in the support plug 2, this valve The wall 16 is in close contact with the blocking wall 5 so that the liquid supply port 6 can be sealed.
The valve wall 16 has a shape in which a bulging portion 16a protrudes from the lower portion of the container-side tip portion of the rotary stopper 12 at the central portion on the right side (left side in the rear view of FIG. 3) of a substantially circular arc. It has become.
In the state of FIG. 1, when the rotary plug 12 is moved in the direction of the arrow and tightly fitted into the support plug 2, the ring-shaped protrusion 17 is fitted into the concave groove 7 of the support plug 2, and the pouring hole 18, 19 is closed by the cylindrical wall of the support plug 2, and the liquid supply port 6 is closed by the valve wall 16.
[0012]
A protrusion 11 is provided on the outer upper portion of the rotary plug 12, and on the other hand, receiving portions 9 a, 9 b, 9 c for engaging with the protrusion 11 are projected on the upper and left sides of the outer edge of the support plug 2. . When the protrusion 11 is tightly fitted in the state of FIG. 1, the protrusion 11 is engaged with the receiving portion 9a, and in this state, a slight resistance is given when the turning plug 12 is turned in the left-right direction, and the pouring plug 1 is closed. So that you can know what it is.
When the turning plug 12 is turned 90 degrees counterclockwise from this state, the pouring hole 18 communicates with the nozzle 3 and the projection reaches the receiving portion 9b, and this receiving portion 9b functions as a stopper. The movement plug 12 does not rotate any further. On the other hand, when it is rotated 90 degrees in the clockwise direction, the pouring hole 19 communicates with the nozzle 3 and the projection reaches the receiving portion 9c. This receiving portion 9c functions as a stopper, and the rotating plug 12 is rotated further. It doesn't move. In either case, the communication state between the extraction hole and the nozzle 3 can be fixed in that state.
[0013]
In the state where the discharge holes 18 and 19 are horizontally opposed, the valve wall 16 closes the entire liquid supply port 6, but when the rotary plug 12 is rotated counterclockwise, the large discharge hole 18 becomes a nozzle. 3, the valve wall 16 opens the liquid supply port 6 and discharges the liquid 20 in the container 21 from the nozzle 3 (see FIG. 4).
In the Kaidosen 12 steps small Note Deana 19 is rotated in the clockwise direction is communicated with the nozzle 3, or bulging portion 16a of the valve wall is shielded from the upper portion of the liquid supply ports 6 remains as it Note Deana Compared with the case of using 18, the opening area of the liquid supply port 6 becomes smaller, and the liquid 20 is poured out from the nozzle 3 with a smaller liquid amount than the above case (see FIG. 5).
In the present embodiment, the amount of liquid 20 supplied from the liquid supply port 6 and the amount of liquid 20 discharged from the nozzle 3 are adapted.
In the above embodiment, the liquid supply port 6 is opened and closed by the arc-shaped valve wall 16, but the tip of the rotary plug 12 is closed with a wall to form two holes, Thereby, the liquid supply port 6 may be opened and closed. In this case, it is also possible to make the amount of liquid supplied to the spout 1 different by making the sizes of the holes different.
[0014]
In addition, a lid 13 for the nozzle 3 is provided below the rotary plug 12 via a bent portion 14 so that the lower end portion of the nozzle 3 can be closed by bending the bent portion 14 at the time of closing. . Since the lid 13 is configured integrally with the rotary stopper 12, in the state where the nozzle 3 is closed with the lid 13, the rotation of the rotary stopper 12 is restricted. It is possible to prevent clogging. Moreover, since it rotates with the rotation of the rotation stopper 12, when it removes from the nozzle 3 and rotates the rotation stopper 12, the lid | cover 13 will change 90 degree | times, Therefore The extraction of the liquid 20 is not disturbed.
In addition, as long as the lid | cover 13 rotates with the rotation stopper 12, the structure of the bending part 14 does not ask | require.
