The present invention relates to a manual whipping beer server that pours beer from a beer can while whipping.

In general, beer foam acts as a lid to retain carbon dioxide gas, and it is said that the fine foam enhances the richness and aroma of beer. In beer halls and the like, a beer server is used that can pressurize the inside of a beer barrel filled with a large amount of beer with carbon dioxide gas, pour beer, and then post-load fine bubbles. Therefore, the beer poured into the glass can be drunk in a state where fine bubbles are appropriately placed on the liquid surface, carbon dioxide gas is retained, and the beer feels delicious.

As a beer server for allowing a beer loaded with such fine bubbles to be drunk at home, the one shown in FIG. 6 (6A) is proposed in the following Patent Document 1.

In this beer server, the dispenser 62 extends diagonally from the attachment portion 61 connected to the mouth 52 of the barrel-shaped large-capacity beer can 51, and the outflow passage 63 is formed inside the dispenser 62. The rotary blade 65 arranged in the outflow path 63 is rotationally driven by the motor 64 attached to the ejector 62. The motor 64 is supplied with power from the battery 67 built in the grip portion 66 extending from the dispenser 62.

The axis of the rotation axis of the rotary blade 65 is orthogonal to the flow direction of the outflow path 63, and the stirring blades of the rotary blade 65 are arranged radially around the rotation axis one by one.

As a result, when pouring beer, the motor 64 is driven to rotate the rotary blade 65, and the beer flowing through the outflow path 63 is agitated to form bubbles.

Further, in Patent Document 2 below, a beer server as shown in FIG. 6 (6B) is proposed. This beer server is separate from a cylindrical storage container 81 that stores a beer can 71 having a normal capacity such as 350 ml in a state where a pull top 72 is opened to form an opening 73, and a mechanical box 82 that is attached to and detached from the upper end thereof. It consists of a body adapter 83.

The mechanical box 82 contains a motor pump and an ultrasonic generator, and is provided with a lever-type operator 84 on the upper surface and a spout 85 on the side surface. The motor pump and the ultrasonic generator are operated by a battery built in the mechanical box 82.

When used as a tabletop type, the glass 74 is placed on the glass receiver 86 at the bottom of the storage container 81 with the mechanical box 82 mounted on the top of the storage container 81, and the operator 84 is tilted. The beer liquid is poured into the glass 74 by the drive of the motor pump, and fine bubbles are formed by the ultrasonic generator and placed on the liquid surface of the beer.

Further, the mechanical box 82 removed from the storage container 81 can be used as a hand-held beer server by attaching it to the top of the beer can 71 via the adapter 83, and can be carried and used on the go.

However, the beer server as described above requires a power source for continuously generating bubbles, and therefore has a problem of high running cost. Further, since a heavy object such as a battery or a motor is built in, when the one described in Patent Document 2 is used as a handheld type, there is a problem that the burden on the arm is large and it is difficult to pour beer.

Therefore, it is an object of the present invention to provide a beer server capable of continuously generating fine bubbles with a lightweight and simple structure without requiring a power source.

In order to solve the above-mentioned problems, the present invention is in a beer server that is attached to and detached from the top of a beer can, agitates the beer flowing through the flow path of the nozzle with the rotation of the stirring blade, foams it, and pours it out.
The operating mechanism for rotating the rotary blade provided with the stirring blade is a lever that is pivotally supported and swings, an initial gear that rotates integrally with the lever, and the rotation of the initial gear is regulated. It is provided with a rotation transmission gear portion that is transmitted to the rotary blade as a rotary motion, and a return spring that urges the lever and the initial gear to return to the initial position.
When the lever is pushed in, the rotary wing body rotates in the forward direction due to the pushing pressure, and when the lever is released from the pushed state, the rotary wing body rotates in the opposite direction due to the urging force of the return spring. I decided to provide something.

Further, the nozzle has a large inner diameter so that the flow path has a circular cross section and a wide gap is secured between the flow path and the outer circumference of the stirring blade from the base side to the middle of the flow direction of the flow path. It was set, and the inner diameter was gradually reduced in a tapered shape from the middle of the flow direction of the flow path to the tip.

Further, the rotary blades are a plurality of pieces provided side by side in the flow direction of the flow path at positions facing each other around the rotation axis and a rotation axis extending so as to be parallel to the flow direction of the flow path of the nozzle. It was made up of the stirring blade.

Further, the stirring blade is assumed to have a saw blade edge formed by repeating a mountain portion and a valley portion at an edge facing downstream in the flow direction of the flow path of the nozzle.

Then, a case containing the operating mechanism for rotating the rotating blade and the base of the nozzle is fixed to a pedestal covering the top of the beer can, and inside the case, a mechanism accommodating chamber in which the operating mechanism is housed. And, it is assumed that the flow path of the nozzle through which beer flows is arranged side by side via the partition wall.

In the manual whipping beer server according to the present invention, not only the rotating blade rotates in the forward direction when the lever is pushed in, but also the rotating blade rotates in the opposite direction when the lever is released from the pushed state. The stirring blade of the rotating blade continuously stirs the beer flowing through the flow path of the nozzle to generate fine bubbles, which can be placed on the liquid surface of the beer.

In addition, because it has a simple manual structure, it does not require heavy objects such as a power supply or motor, it does not require running costs, and it is a lightweight and easy-to-use handheld type that can be easily used on a daily basis and when going out. It can be carried around, and after use, it only needs to be lightly rinsed through the flow path of the beer, and there is no need for disassembly.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

As shown in FIG. 1, this manual whipping beer server is attached to and detached from the top of a beer can 1 having a normal capacity of 350 ml or 500 ml.

The case 11 containing the operating mechanism of the beer server is formed in half on the left and right and is connected by screws, and is fixed to a pedestal 12 that covers the top of the beer can 1. The base of the cylindrical nozzle 13 is inserted and fixed to the front portion of the case 11, and the nozzle 13 projects forward from the case 11. A rotating blade 14 is inserted into the nozzle 13, and the rotating blade 14 is provided with a stirring blade 15.

As shown in FIGS. 2 to 4, inside the case 11, a mechanism accommodating chamber 11a in which an operation mechanism for rotating the rotary blade 14 is housed, and a flow path of a nozzle 13 in which the stirring blade 15 is inserted are inserted. 16 and 16 are arranged side by side via the partition wall 11b.

The pedestal 12 is provided with an outlet 12a for flowing out beer from the beer can 1 and an air hole 12b for introducing atmospheric pressure on the mounting surface of the case 11. Further, a fitting groove 12c into which the winding portion 1a on the outer periphery of the top of the beer can 1 is press-fitted is provided on the back side of the outer peripheral portion, and a picking piece 12d for removing from the beer can 1 is provided on the rear portion of the outer peripheral edge. ..

The nozzle 13 has a large diameter portion 13a in which the stirring blade 15 is inserted from the base portion to the middle of the flow direction of the flow path 16, and a tapered portion 13b having a narrowed tip side. An inflow port 13c communicating with the outflow port 12a of the pedestal 12 is provided on the outer periphery of the base portion of the large diameter portion 13a.

The rotary wing body 14 is provided with a plurality of stirring blades 15 around a rotary shaft 14a extending so as to be parallel to the flow direction of the flow path 16 of the nozzle 13, and the rotary shaft 14a is a partition wall 11b of the case 11. It is inserted through a sleeve 11c that penetrates the sleeve and is rotatably supported.

The stirring blades 15 are arranged side by side at opposite positions around the rotation shaft 14a so as to form a plurality of pairs with a slight interval in the flow direction of the flow path 16. The extending lengths of the stirring blades 15 from the rotating shaft 14a are the same.

Regarding the dimensional relationship between the stirring blade 15 and the nozzle 13, the inner diameter of the nozzle 13 is set large so that a relatively wide gap is formed between the large diameter portion 13a of the nozzle 13 and the outer circumference of the stirring blade 15, and the tapered portion 13b has a large inner diameter. , The inner diameter of the nozzle 13 is gradually reduced toward the tip.

Further, the stirring blade 15 has a saw blade edge formed by repeating peaks and valleys at an edge of the nozzle 13 facing downstream in the flow direction of the flow path 16.

The operation mechanism for rotating the rotary blade 14 is a swinging lever 17, a fan-shaped initial gear 18 that rotates integrally with the lever 17, and a rotary blade whose rotation of the initial gear 18 is a speed-controlled rotary motion. It includes a rotation transmission gear portion 19 that transmits to 14, and a return spring 20 that urges the lever 17 and the initial gear 18 to return to the initial position.

The lever 17 and the initial gear 18 are pivotally supported by the case 11 by the shaft 21, and the initial gear 18 rotates within a predetermined angle range. The rotation transmission gear portion 19 includes a first gear 19a ₁ , a second gear 19a ₂ , a third gear 19b ₁ , a fourth gear 19b ₂ , a fifth gear 19c ₁ , a sixth gear 19c ₂ , and a seventh gear 19d. There is.

The first gear 19a ₁ and the second gear 19a ₂ are integrally molded, and the fifth gear 19c ₁ and the sixth gear 19c ₂ are also integrally molded. It is supported. The third gear 19b ₁ and the fourth gear 19b ₂ are pivotally supported by the case 11 so as to be integrally rotated by the shaft 23.

The shafts 21, 22, and 23 are made of metal in consideration of durability, unlike other constituent members made of plastic.

The first gear 19a ₁ that meshes with the initial gear 18 is a pinion, and the second gear 19a ₂ having a diameter larger than that of the first gear 19a ₁ rotates at a constant speed with the integrated first gear 19a ₁ and is second. The rotation is accelerated and transmitted to the third gear 19b ₁ having a diameter slightly smaller than that of the gear 19a ₂ .

The fourth gear 19b ₂ , which rotates integrally with the third gear 19b ₁ , has a larger diameter than the third gear 19b ₁ , and speeds up and transmits the rotation to the fifth gear 19c ₁ , which is a pinion.

The sixth gear 19c ₂ , which is integrated with the fifth gear 19c ₁ and rotates at a constant speed, is a crown gear unlike other gears that are spur gears, and is integrally molded with the shaft end of the rotating shaft 14a of the rotating blade 14. It meshes with the 7th gear 19d of the pinion, converts the axial direction of rotation by 90 °, and accelerates and transmits the rotation to the 7th gear 19d.

The return spring 20 is a tension coil spring, one end of which is locked to a protrusion on the inner surface of the case 11, and the other end of which is locked to a protrusion on one side surface of the initial gear 18.

In such an operation mechanism, when the lever 17 is pushed in, the rotary wing body 14 rotates in the positive direction due to the pushing pressure, and when the lever 17 is released from the pushed state, the rotating wing body 14 is moved by the urging force of the return spring 20. Rotate in the opposite direction.

When pouring beer using the manual whipping beer server having the above configuration, the manual whipping beer server is placed on the top of the beer can 1 with the pull top 2 at the top of the beer can 1 opened to form the opening 3. Install. At this time, the position of the opening 3 of the beer can 1 and the position of the outlet 12a of the pedestal 12 and the inlet 13c of the nozzle 13 are aligned.

Then, as shown in FIG. 5 (5A), the glass 31 is slanted, the beer can 1 is tilted, and the beer flowing out from the tip of the nozzle 13 is placed along the inside of the glass 31 for 6 minutes. Pour the beer from the eyes to the 7th minute.

At this time, as described above, in the large diameter portion 13a of the nozzle 13, a relatively wide gap is secured between the inner peripheral surface thereof and the outer periphery of the stirring blade 15, so that the beer does not foam and the nozzle 13 does not foam. It passes through the flow path 16 of the above and is poured into the glass 31 as a transparent liquid.

Next, as shown in FIG. 5 (5B), when the glass 31 is placed on a flat place, the beer can 1 is tilted, and the lever 17 is pushed in, the rotating blade 14 rotates in the positive direction due to the pushing pressure. The beer flowing through the flow path 16 is stirred by the stirring blade 15 and foamed, and the foam flowing out from the tip of the nozzle 13 is poured onto the liquid surface of the beer in the glass 31.

After that, when the lever 17 is released from the pushed state, the rotating blade 14 is rotated in the opposite direction by the urging force of the return spring 20, and the beer flowing through the flow path 16 is also stirred by the stirring blade 15 and foamed by this rotation. , The bubbles flowing out from the tip of the nozzle 13 are continuously poured onto the liquid surface of the beer in the glass 31.

When an appropriate amount of foam is placed on the liquid surface of the beer in the glass 31 by repeating the operation of pushing the lever 17 and the operation of releasing the lever 17 in this way, the pouring of the beer is completed.

In the manual whipping beer server as described above, not only the rotating blade 14 rotates in the forward direction by pushing the lever 17, but also the rotating blade 14 rotates in the opposite direction when the lever 17 is released from the pushed state. Since it rotates, the stirring blade 15 of the rotating blade 14 continuously stirs the beer flowing through the flow path 16 of the nozzle 13, generates fine bubbles, and can be placed on the liquid surface of the beer, resulting in creamy foaming. You can taste the beer.

In addition, because it has a simple manual structure, it does not require heavy objects such as a power supply or motor, it does not require running costs, and it is a lightweight and easy-to-use handheld type that can be easily used on a daily basis and when going out. It can be carried around, and after use, it is only necessary to lightly rinse the flow path 16 of the nozzle 13 through which beer flows, and there is no need for disassembly or the like.

In selecting the shape of the nozzle 13 in the above embodiment, six types of shapes as shown in Table 1 were verified.

As a result, when pouring beer, a cylindrical one with a narrowed tip, such as the sixth one, is used when the stirring blade is poured without foaming as it is, and when the stirring blade is foamed and poured. Since the best results were obtained in both cases, a nozzle 13 having a shape based on the sixth shape was adopted as the nozzle 13 of the above embodiment.

Further, in selecting the shape of the stirring blade 15 of the rotating blade 14, six types of shapes as shown in Table 2 were verified. In this verification, a jig for electrically rotating the rotary blade 14 was used, and the nozzle 13 was unified to the sixth one in Table 1.

As a result, as in "F", a plurality of stirring blades are provided at opposite positions around the rotation axis, and the end edge facing the downstream side in the flow direction is a saw blade edge, but the passage resistance of beer is small. Since unintended foaming does not occur, there is almost no shaft runout during rotation, and plastic molding is relatively easy, the stirring blade 15 of the above embodiment is based on the shape of "F". ..

Further, in selecting the sizes of the nozzle 13 and the stirring blade 15, verification was performed for three types of cases as shown in Tables 3 and 4.

As a result, like "B", the inner diameter of the large diameter portion 13a of the nozzle 13 is 13 mm, and the distance (W) between the tips of the opposing stirring blades 15 is 11 mm. This combination was adopted because it was judged that there was little beer liquefaction (liquefaction) and the foam quality was good.
