Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an improvement of a beer dispensing device attached to a medium-capacity beer container.

[Conventional technology]

Recently, it has become common to pour out beer from two or three medium-capacity beer containers using a pouring tool.

Most of these pouring tools are attached to the top of the beer container, and if you stop pouring beer and stand the beer container upright, the beer and its foam (hereinafter referred to as both) remaining in the pouring tool will be removed. Bubbles (including foam) often bubbled over due to the pressure inside the container.

The first pouring device used for medium-capacity beer containers was a straight one;
It often caused boilovers.

When we consider the cause of this, we find that, in general, due to the characteristics of the pouring tool, even when the container is tilted and a full beer is poured out, the tip of the pouring tool sticks out beyond the shoulder of the container. It is necessary for the beer to flow out, so in the case of a straight pouring device, in order to meet these conditions,
It is necessary to make the spout pipe quite long, and therefore the contact area between the bubbles inside the spout pipe and the wall surface of the spout pipe becomes large, which increases the resistance to the flow of the foam mass and causes the flow of the spout pipe to increase. Unless the inner diameter was made considerably larger, the foam mass remained in the spout tube for a long time.

Later, in pursuit of ease of pouring, curved pouring tools appeared.

Generally, when pouring liquid from a container, a teapot,
As seen on the spouts of water jugs, medicine cans, earthenware bottles, etc.
It is easier to pour if the tip of the pouring tube is horizontal, that is, the angle of inclination to the vertical line is close to 90 degrees, and if the tip of the pouring tube is thin and the base is thick.

For this reason, the dispensing tool for medium-capacity beer containers also has an angle of inclination of the dispensing pipe with respect to the vertical line, that is,
Adjust the refraction angle of the bent dispensing tool to 100 degrees or more.
Although the temperature was set at 134 degrees, most of the pipes had the same thickness at the tip and base.

Generally, the boiling over phenomenon tends to occur not only when the spout tube is lengthened, but also when the inner diameter of the spout tube is made small.

If the inner diameter of the spout pipe is less than 10 mm, the spout pipe will not be damaged not only when the spout pipe is straight, but also when the spout pipe is bent almost at right angles from the base and made as short as possible. , almost completely filled with foam, and often boils over.

However, if the inner diameter of the spout pipe exceeds 20 mm, the flow rate will be too large when the pipe is filled to the brim with beer, which will often cause the beer to splatter or overflow from the glass.

The upper part of the mass of beer foam, which has viscoelasticity even if the inner diameter of the base of the spouting pipe is within the range of 10 to 20 mm, adheres to the sloped part of the bent part of the spouting pipe, and the lower part of the mass is As the foam gradually receded, the entire mass of foam filled the spouting pipe, making it easy for the foam to boil over.

[Problem that the invention attempts to solve]

The problem that the present inventors are trying to solve with this invention is to prevent the accumulation of beer foam as much as possible in the dispensing tool that is attached to the top of such a medium-capacity beer container and has a bent dispensing pipe. The purpose is to prevent beer foam in the pouring device from bubbling over due to an increase in carbon dioxide pressure in the container.

[Means for solving problems]

As a means to solve this problem, the inventors of the present invention developed a dispensing tool that is attached to the top of a medium-capacity beer container and has a bent dispensing pipe, in which the length of the rising part of the dispensing pipe is 10 ~30mm, inner diameter 10~20mm
The present invention provides a new beer dispensing device characterized in that the ratio of the area of the spout of the dispensing pipe to the beer inlet area of the rising portion is 1.2 to 3.0, and the bending angle is 135 to 150 degrees. be.

The dispensing tool referred to in the present invention may be one made of polyethylene, polypropylene, polystyrene, polyester, or other synthetic resin, and has at least one dispensing pipe, with an air introduction pipe attached. Good too. Further, the spout tube may have a small-diameter sub spout in addition to the one main spout. Further, the base of the dispensing tool is provided with a mounting part having a known conventional means such as a collar, an annular projection, or a packing so that the dispensing tool can be airtightly mounted to the opening of the container.

In addition, the rising part of the spouting pipe of the spouting tool in the present invention is the part of the spouting pipe that rises directly upward from the bottom when the spouting tool is attached to the beer container, that is,
This refers to the part of the pouring pipe from the beer inlet to the bend. Also, the part from the bend to the spout is called the bend.

The shape of the cross section of the beer inlet at the rising part is generally as follows.
The shape may be any shape, such as a circle, a shape without a circular portion on the outer periphery of the air pipe, or a thick crescent shape.

The shape of the spout may be any shape, such as a circle, but if the cross section of the beer inlet at the rising part is circular, preferably the spout has a wide area, such as a vertically elongated oval. It is better to devise ways to make it more difficult for the worn parts to come into contact with the flow of beer.

If the ratio of the area of the spout of the spout to the beer inlet area of the rising part is less than 1.2, the bent part will often be filled with beer, and if it exceeds 3.0, the area of the spout should be increased. However, the effect of preventing spillage does not improve proportionally, and on the contrary, it makes it difficult to pour beer.

If the area ratio is 1.2 or more and close to 1.2,
Bubbles of foam stay on the slope of the bend, and if the bend angle is less than 135 degrees, the slope is gentle, so the flow rate of the bubble will be slow.

In addition, when the temperature exceeds 150 degrees, the entire length of the spout pipe becomes longer, the length of the foam lump that stays becomes longer, and the distance that the foam flows down becomes longer, so it takes a long time for the foam lump to flow down. Requires.

If the area ratio is close to 3.0, even if the bending angle is less than 135 degrees, the bubbles at the bend will
At the end of pouring, the foam flows away towards the dirt, etc., and the foam no longer stays at the bent part. On the other hand, when the temperature exceeds 150 degrees, the bubbles at the bend tend to flow toward the container, and the amount of bubbles remaining increases gradually, as in the case where the area ratio is close to 1.2.
It takes a long time for the foam to flow down.

Further, boiling over cannot be completely prevented simply by setting the ratio of the area of the spout of the pouring pipe to the area of the beer inlet of the rising portion to 1.2 to 3.0. In order to exhibit the effect of preventing boiling over by setting the area ratio to 1.2 to 3.0, it is necessary that the spouting pipe be bent to a certain extent. The reason for this is that when the spout is bent, the direction in which the beer is poured using the spout is determined, and the beer is always poured from a certain point on the spout, so the upper end is on the opposite side of the spout. This is because there is always a portion that does not come into contact with the beer, which reduces the contact area of the mass of foam and promotes the flow of foam.

Moreover, if the bending angle is only 135 to 150 degrees, the effect of preventing boiling over from boiling over will not be sufficiently exhibited. If the ratio of the area of the spout of the spout to the beer inlet area of the rising part is less than 1.2, even if the inner diameter of the rising part is within the range of 10 mm to 20 mm, the mass of foam will not reach the inner wall of the bent part. It comes into contact with the top surface and completely closes the bend. If the inner diameter of the rising part is close to 10 mm, no matter what the angle of the bending part is, there will be almost no flow down, and even if it is close to 20 mm, the flow rate will be very slow.

[Effect]

In the beer pouring device according to the present invention, even if the inner diameter of the rising portion is within the range of 10 to 20 mm, the area of the spout is
Since it is 1.2 to 3.0 times larger, there is no contact when pouring beer, and in many cases, air remains at the top of the inner surface of the spout.

Therefore, when the container is stood up after pouring beer, the contact area between the foam mass and the inner surface of the spout becomes small, making it easier for the foam mass to slide into the container.

In addition, in this invention, the angle between the rising part and the bent part is 135 to 150 degrees, so if the spout pipe is straight, or the angle with the bent part is 135 to 150 degrees,
The overall length of the spout pipe is shorter than when the angle is over 150 degrees, and the mass of beer foam can slide off the bend more smoothly than when the angle is less than 135 degrees. As a result, beer foam does not accumulate in the pouring pipe, and no boiling over occurs.

〔Example〕

1 and 2 are a longitudinal sectional view and a bottom view, respectively, showing an example of a pouring device according to the present invention, and FIG. 3 is a longitudinal sectional view showing another embodiment. In these figures, 1 is a rising part, 2 is a bent part, 3 is a spout, 4 is an air pipe, 5 is a mounting part, 6 is a ring-shaped small projection for mounting, and 7 is a collar.

In FIG. 1, in order to fully exhibit the effects of the present invention, a bent portion 2 having a wide spout area is shown.
The length L ₁ of the rising portion 1 is made larger than the length L ₂ of the rising portion 1 .

However, if L ₁ is too long, the beer foam will easily scatter due to centrifugal force when pouring beer is stopped and the container is set up, while if it is too short, it will be difficult to pour the beer and at the same time the top plate will be damaged when the container is set up. Beer foam may drip. Therefore, the length of L ₁ is 35
~45 mm is preferred. Also, if L ₂ is too long, it will exhibit the same drawbacks as if L ₁ is long, while if it is too short, it will be difficult to pour, especially into low glasses.
Therefore, the length of _L2 is preferably 10 to 30 mm.

The area ratio between the beer inlet of the rising part 1 and the spout part 2 is 1.5 in the case of Fig. 1, and in the case of Fig. 3.
It is 2.2. Further, the angle between the rising portion 1 and the spout portion 2 is 135 degrees in the case of FIG. 1 and 145 degrees in the case of FIG. 3.

In addition, the longer the length _L3 of the part of the air pipe inserted into the container, the better.
If the length is too long, it will be difficult to manufacture the pouring tool, so it is preferably about 15 to 25 mm, and the inner diameter should be about 3 to 6 mm. Although such an air pipe is attached to the outside of the spout pipe in the drawing, it may be placed inside the spout pipe.

The above numerical values vary depending on the capacity and shape of the container, but if it is within the above numerical values,
It is possible to provide a beer pouring tool that does not cause boiling over.

[Effect of idea]

Since the beer dispensing device according to the present invention has the above-described structure, when it is attached to the top of a medium-capacity beer container and used, it is extremely easy to pour, and also prevents beer from boiling over due to carbon dioxide pressure in the container. , can be completely prevented.
