For example, by opening and closing the sealing plate 5 of the cylinder 4 filled with pressurized fluid such as beer, and causing the pressurized fluid to flow into the container 2, the pressure inside the container 2 is increased. This pressure causes the material to be poured out in the container 2 to be poured out from a spout 6 provided in the pouring device.

This dispensing device 1 includes a cylinder storage member 7 which stores a cylinder 4 and has a dispensing passage 10 that communicates with a spout 6 for dispensing the material to be poured out in the container 2; An opening/closing mechanism housing member 8 housing an opening/closing mechanism for opening and closing the sealing plate 5 of the cylinder 4; a partition wall member 9 that partitions the cylinder housing member 7 and the opening/closing mechanism housing member 8 and in which the opening/closing mechanism is disposed; and a ring member 11 for attaching the dispensing device 1 to the container 2.

The cylinder 4 stored in the dispensing device 1 is filled with a pressurized fluid such as carbon dioxide gas, and a sealing plate 5 is removed on the top side of the cylinder 4 to close the cylinder 4. This is what happens.

1. The cylinder storage part 7a of the cylinder storage member 7 that stores the cylinder 4 filled with carbon dioxide gas has a size that allows the cylinder 4 to be press-fitted to the partition wall part 9a of the partition wall member 9, which will be described later, with the sealing plate 5. At the same time, a carbon dioxide gas outlet 12 is provided on both sides thereof.

Further, the cylinder storage member 7 is provided with a two-sided plate 13 on its upper surface side, which is coupled to the partition wall member 9. and,
A pouring passage 10 for pouring out the object to be poured in the container 2 is attached to the upper surface plate 13 along an example of the cylinder storage section 7a. A valve body 14 is provided in the middle of this outlet illumination passage 10 with a conical coil spring 1.

Four crimping parts 17 are provided to be crimped. Inside the crimp recess 17, an outflow recess 1B (not shown) is formed in the shape of a cross, through which the carbon dioxide gas in the cylinder 4 is poured out into the container 2 when the sealing plate 5 is opened. has been done.

A safety valve 19 is provided on the top plate 13 of the cylinder storage member 7 as a safety device in case the pressure inside the container 2 rises abnormally, and a safety valve 19 is provided on the partition wall member 9. , a vent hole 20 for releasing the pressure inside the container 2 to the outside of the device 1 when the safety valve I9 is opened.
is provided.

Further, the partition wall member 9 is provided with a communication path 21 at a position opposite to the pouring passage 10 of the cylinder storing member 7, which communicates the pouring passage 10 with the opening/closing mechanism storing member 8, A spout 6 for pouring out the material to be poured in the container 2 is provided in the middle of the communication path 21 so as to protrude outward.

A flange portion 22 is provided on the outer peripheral edge of the lower end side of the partition wall member 9, and is welded to the upper surface plate 13 of the pump storage member 7.

Therefore, when the carbon dioxide gas in the cylinder 4 is discharged from the cylinder 4, it flows out into the container 2 through the outlet 12.

Next, while opening and closing the sealing plate 5 of the cylinder 4,
The opening/closing mechanism that opens and closes the valve body 14 of the pouring passage 10 is located in the opening/closing mechanism storage member 8 of the pouring device l as shown in FIGS. 1, 5, and 7. Part 9
It is arranged and configured on the top surface.

First, a fitting portion 24 into which the support member 23 is fitted is provided on the upper surface side of the partition wall member 9 facing the press-fitting recess 7.

In this support member 23, the fitting hole 2 of the section 24 is
5, and a pressed piece 29 having a pressed protrusion 28 pressed by a rotating member 27, which will be described later, on one end thereof. And, the fitting part 23 mentioned in "1" is "1"
A sharp object 30 is attached that passes through the partition wall 9a of the partition wall member 9 and opens and closes the sealing plate 5 of the cylinder 2. This sharp object 30 opens the sealing plate 5 of the cylinder q and forms a discharge port 31 through which carbon dioxide gas protrudes, and
This serves as an on-off valve for the sealing plate 5.

Next, in the support member 23, a coil spring 33 is disposed from the top plate 32 side of the opening/closing mechanism storage member 8 to between the support members 23, and the support member 23 is moved toward the partition wall portion 9a side. It is pressed and energized. However, this coil spring 33 does not have enough pressing force to open the sealing plate 5 of the cylinder q when it is closed.

Therefore, the sealing plate 5 is opened by the opening operation member 34 attached to the upper surface of the support member 23.

The cap opening operation member 34 is attached to a cap opening member fitting hole 85 drilled in the top plate 32 of the opening/closing mechanism storage member 8 at a position corresponding to the support member 23, and is further attached to the rotating lever 3.
5, it is rotatable. As shown in FIGS. 5 and 7, the opening operating member 34 is provided with a first four portion 36 and a second recess 37 on its lower surface side, as shown in FIGS. 5 and 7.
The space between the first four parts 36 and the second four parts 37 is a pressing part 39 that presses the bulge part 38 provided on the upper surface of the support member 23.

The first recess 36 and the second recess 37 of this opening operation member 34 are provided with different levels, and the second recess 3
6 is opened shallower than the first recess 37. This allows the level difference of the first recess 36 to be adjusted to the support member 23 before opening.
If the sharp body 30 slides, the throttling effect of the sharp object 30 cannot be obtained, and the amount of carbon dioxide gas discharged from the discharge port 31 becomes too large. This is to enable adjustment of the amount of carbon dioxide gas discharged from 31.

Before opening the sealing plate 5, as shown in FIG.

Then, as shown in FIG.
When the concave portion 37 corresponds to the bulging portion 38 of the support member 23, the suppression of the support member 23 by the opening operation member 34 is released. However, since the support member 23 is pressed toward the partition wall 9a by the coil spring 33, the sharp object 30 of the support member 23 closes the sealing plate 5 even when the pressure by the opening operation member 34 is released. It is energized to the completed state. Therefore, at a position corresponding to the second recess 37, the support member 23 is moved to the second recess 37.
A sliding operation is possible by the step amount, and when the cylinder 4 is opened and closed, the amount of carbon dioxide gas discharged from the cylinder 4 is adjusted.

When this supporting member 23 is slid by a rotating member 27 (to be described later) as shown in FIG.
This means that opening and closing operations can be performed.

Next, a fitting hole 40 is bored in the top plate 32 of the opening/closing mechanism storage member 8, which faces the communication path 21 provided in the partition wall member 9, and this fitting hole 40 and the connection path The opening/closing operation member 41 is removed over 21 seconds. The opening/closing operation member 41 includes a pressed portion 42 fitted into the fitting hole 40 and an operation rod 43 extending from the lower surface side of the pressed portion.
This operating rod 43 is inserted into the connecting passage 21 indicated by 1 and connected to the valve body 14 provided in the dispensing passage 10. Therefore, by pressing the pressed portion 42, the valve body I4 is directly pressed against the conical coil spring 15, so that the negative outlet passage IO can be opened and closed. Further, the operating rod 43 is provided with a tapered portion 44 in the middle thereof, and when the pouring passage 10 is opened, the opening 45 of the communication passage 21 on the opening/closing mechanism side
can be closed.

Therefore, the object to be poured, such as beer, can be discharged from the spout 6 provided in the middle of the communication path 21.

Note that when the opening/closing operation member 41 is not pressed, the recording port 46 is opened, so that the material to be poured can be poured without leaving it in the spout 6 when the valve body 14 is opened.

Furthermore, rotating members 27 are provided on both sides of the -L end of the operating rod 43.
An operating section 46 is provided which can be rotated by pressing.

In addition, flange portions 47 are provided on both sides of the lower edge of the pressed portion 42, and when the flange portions 47 come into contact with the inside of the opening/closing mechanism storage member 8, the rotation of the opening/closing operation member 41 is suppressed and the above-mentioned The operating portion 46 is positioned so as to be able to press the rotating member 27.

The rotating member 27 that is pressed by the operating section 46 is formed as a plate with a planar shape of approximately 11 characters, as shown in FIG.
A position facing the operating section 46 is a pressed piece 48,
The opposite side of the pressed piece 48 serves as a pressing piece 49 that presses the support member 23 . A pivot piece 50 is provided protruding from the outer side of the suppression piece 49, and the fitting tube of the partition wall member 9 is rotatably attached to a pivot support 51 provided on the opening/closing operation member 41 side of the portion 24. It is pivotally supported. Therefore, the rotating member 27 is rotatable around the pivot piece 50. Note that four escape parts 52 are formed on the inner side of the pressing piece 49 of the rotating member 27 so that the fitting cylinder does not come into contact with the part 24.

Therefore, when the pressed piece 48 of the rotary member 27 is pressed by the operating portion 46 of the opening/closing operation member 41 in item 1, the rotating member 27 rotates around the pivot piece 50 in item 1. The pressing piece 49 of the rotary member 27 presses the pressed protrusion 28 of the support portion 10A23, and the support member 23 is raised within the fitting tube portion 24.

Next, the opening/closing mechanism storage member 8, which is attached to cover the upper surface of the partition wall member 9 attached to the cylinder storage portion 7, has the main body of the device 1 on the base end side of the upper opening 3 of the container 2.

A locking protrusion 60a is provided at the tip of the guide shaft 60, and a locking portion 65a is provided at the tip of the boss hole 65 to prevent the opening/closing mechanism operating body 61 from being removed.

Furthermore, a sliding step 66 on which the opening/closing lever 62 slides is provided on the side of the top plate 32 of the opening/closing mechanism storage member 8 on which the rotating lever 35 is mounted.

Then, the opening/closing mechanism operating body 61 on this sliding step portion 66 side
A Q-limiting protrusion 67 is extended so as to cover the step 66 when the opening/closing mechanism operating body 61 is pressed, leaving a relief portion 75 of the opening/closing lever 62 at the step 66. Note that a guide piece 68 is installed on one side end of the sliding step 66, and a guide piece 69 provided inside one example side of the regulating protrusion 67 of the opening/closing mechanism operating body 61 is installed. This engagement is intended to prevent the opening/closing mechanism operating body 61 from rotating.

The opening/closing lever 62 rotates the rotating lever 35 to open the cylinder 4, and the opening/closing mechanism operating body 61
This serves as a fall prevention member when not in use.

The opening/closing lever 62 is rotatably fitted to the guide shaft 60 through a fitting hole 80, and one end of the opening/closing lever 62 is connected to a connecting portion 70 toward the sliding step 66, which is the sliding range of the opening/closing lever 62. It extends to the hanging portion 71 through the opening. That is, as shown in FIGS. 1 and 2, the opening/closing lever 62 has a first hanging portion 72 extending toward the sliding step portion 66 by a connecting portion 70 and hanging down along the side wall 8a of the storage portion. , the lower end of the first hanging portion 72 is the step surface 66a of the sliding step portion 66.
The second hanging part 74 has a stepped part 73 at a position where it abuts on the second hanging part 74.

Therefore, as shown in FIG. 4, when the stepped portion 73 of the opening/closing lever 62 is in a position where it comes into contact with the regulating protrusion 67 of the opening/closing mechanism operating body 61, this stepped portion 73 The second hanging portion 74 is rotated to position the opening/closing lever 62 in the direction of the arrow X in FIG. As shown in Figure 8, only when
The opening/closing mechanism operating body 61 can be lowered, and by lowering the opening/closing mechanism operating body 61, the opening/closing operating member 41 can be pressed.

Further, an abutting protrusion 76 is provided on the inner surface of the upper end of the first hanging portion 72 to abut against the rotary lever 35 . Therefore, when the opening/closing lever 62 is rotated in the direction of the arrow X in FIG. It is now possible to open the bottle. In addition, this rotation lever 35
does not move together with the rotation of the opening/closing lever 62 in the opposite direction to the aforementioned rotational direction, and once the cylinder 4 is opened, the opening/closing lever 62 cannot be opened depending on the next rotation of the opening/closing lever 62. is no longer possible. This is to prevent the sharp object 30 from deforming the shape of the discharge port 31 due to repeated opening operations.

Further, the ring member II is provided with a rotation regulating protrusion 82 that regulates the rotation of the opening/closing lever 62 before the device 1 is attached to the container 2. Therefore, in order to attach the device 1 to the opening 3 of the container 2, the opening/closing lever 62 must be removed by rotating the ring member 11 and locking the container 2. Cylinder 4 cannot be opened.

Next, the operation of dispensing from the container 2 using the dispensing device 1 according to the present invention having the above-described configuration will be explained.

First, insert the vinyl pipe 84 between the lower ends of the former m path 10 of the dispensing device 1. This is for extending the 1 m pouring path 10 to the bottom of the pipe.

Then, the fitting cylindrical portion 53 of the pouring device 1 is fitted into the opening 3 of the container 2. Then, the ring member 11 is rotated in the direction of an arrow 86 provided on the "-" face of the ring member 11. At this time, the rotation restriction protrusion 82 provided on the ring member 11 moves to the rotation restriction release position of the opening/closing lever 62, and the opening/closing lever 62 becomes able to rotate.

Then, a daily use pipe 87 is attached to the spout 6 of the device 1. This daily pouring pipe 87 is for making it easier to pour the pouring material in the container 2 into kelp etc., and is slanted so that the spout at its tip faces downward.

Next, the opening/closing lever 62 is moved to the relief part 75 of the sliding cutting part 66.
Rotate to the side. Due to this rotation of the opening/closing lever 62, the abutting protrusion 76 of the opening/closing lever 62 causes the rotation lever 35 to rotate. As the rotary lever 35 rotates, the opening operation member 34 attached to the rotary lever 35 presses the support member 23, as shown in FIG. The body 30 opens the sealing plate 5 of the cylinder 4 to form the discharge port 31. However, since the sharp object 30 is pressed by the coil spring 33, even when the upper surface bulging portion 38 of the support member 23 is located at the second four portions 37 of the cap opening operation member 34, the seal is closed. The plate 5 is regulated to remain closed, and the support member 23 can freely slide in the second recess 37 of the opening operation member 34.

Further, when the opening/closing lever 62 is rotated by the relief part 75 of the sliding step part 66, the lowering restriction of the opening/closing mechanism operating body 61 by the lowering restriction protrusion 82 and the stepped part 73 of the opening/closing lever 62 is released.

Therefore, when the opening/closing mechanism operating body 61 is pressed, the pressing operation piece 64 presses the pressed portion 42 of the opening/closing operating member 41 as the opening/closing mechanism operating body 61 descends. Then, the operation section 46 of the opening/closing operation member 41 rotates the rotation member 27. Due to this rotation of the rotating member 27, the rotating member 27
The pressing piece 49 presses the pressed protrusion 28 of the support member 23 upwardly against the coil spring 33.

As a result, as shown in FIG. 9, the support member 23 is slid upward within the fitting portion 24, and the sharp object 30 attached to the fitting portion 25 is moved toward the Bonpei sealing plate 5. The opening operation is performed at a distance from the discharge port 31.

By opening the cylinder 4, carbon dioxide gas flows out from inside the cylinder 4 to the pump, and the outflow port 12 of the cylinder storage member 7
The water flows out into the container 2 from above.

Further, when the opening/closing operation member 41 is pressed, the valve body 14 connected to the tip of the operating rod 43 of the opening/closing operation member 41 resists the elastic force of the conical coil spring 15. It is lowered to open the pouring passage 10.

Therefore, the carbon dioxide gas in the cylinder 2 is discharged into the container 2, increasing the pressure in the container 1, thereby increasing the pressure inside the container 2.
The object to be poured, such as beer, stored therein can be poured out through the opened pouring passage 10 and from the spout 6 as shown in FIG. 8.

The opening/closing operation member 41 is operated by the elastic force of the coil spring 33 that presses the support member 23 via the rotating portion +Jf 27 and the valve body 1 of the spouting passage 10.
4 is constantly urged upward by a conical coil spring 15 that urges it upward.

Therefore, when the pressure on the opening/closing mechanism operating body 61 is released, the opening/closing operating member 41 is returned to the state before being pressed by the biasing force of the coil spring 33 and the conical coil spring 15, and the sealing plate 5 of the cylinder 4 is opened. Discharge port 31
is closed by the sharp body 30 of the support member 23, and the pouring passage 10 is closed by the valve body 14, and the opening/closing mechanism operating body 61 is pushed back upward.

Therefore, only by pressing and releasing the opening/closing mechanism operating body 61, the material to be poured in the container 2 can be poured out in the required amount.

<Effects of the Invention> Therefore, according to the present invention, the dispensing device is inserted into the opening of the container, and the protrusion formed on the inner peripheral surface of the ring member is inserted into the proximal end of the opening/closing mechanism storage section. Rotates along an inclined surface portion formed on the periphery and engages with a retaining portion of the inclined surface portion, so that the fitting cylinder portion attaches to the opening of the container, and the sealing member ensures airtightness. As a result, the main body of the device can be attached to the opening of the container described in 1. with a tight fit.

Furthermore, when removing the device main body from the container, the ring member is reversed to release the fitting cylinder portion, and the container The high pressure gas inside can be vented.

Therefore, it can be easily attached to the container without providing a threaded portion at the opening of the container, and when removing the pouring device, it can be removed after venting the high pressure gas in the container, It is possible to prevent the spouting device from being blown away when the spouting device is removed, and safety in removing the device can be ensured.
