  The present invention relates to a pouring device that is attached to a portable container and that dispenses an effervescent beverage contained in the portable container.

  Conventionally, sparkling beverages typified by beer (hereinafter also referred to as “beer etc.”), when poured into a container such as a mug or glass (hereinafter referred to as “jog etc.”), flavor, mouthfeel, In order to improve the appearance over the throat and the appearance, it is preferred that a foam layer of about 30% is formed on a layer of about 70% of beer, and the foam is made up of carbonic acid dissolved in beer. In order to delay omission and oxidation of beer and the like, fine bubbles last longer, and beer and other flavors last longer, so it is said that creamy is better.

  At stores such as beer halls, beer gardens, and pubs (hereinafter referred to as “beer halls”), beer packed in barrels is poured into mugs and the like using a dedicated beer dispenser. At this time, in order to form a creamy foam layer on a layer of beer, etc., skill is required in adjusting the angle of the mug, pouring cock operation, pouring amount, gas pressure, etc. when pouring beer etc. It is necessary.

  In order to easily obtain creamy foam even if it is not skillful in such a beer extraction process, Patent Document 1 proposes a tap with an ultrasonic generating element attached to the extraction flow path of the beer dispenser. Has been. According to such an apparatus, it became possible to form creamy bubbles easily even without being skilled.

  By the way, in beer halls, etc., in addition to providing beer etc. in individual mugs from beer dispensers, services provided to customers using portable containers called pitchers that can hold several glasses of beer etc. Has also been done. The beer provided by the pitcher is dispensed separately from the pitcher into individual mugs at each table.

  The pitcher is made of resin and has a capacity of about 1 to 2 liters for business use. When the pitcher is fully filled with beer, the weight of the beer and the pitcher itself exceeds 2 kg. It may become heavy. When a customer who is unfamiliar with beer, etc., handles such a heavy pitcher and pours it from a pitcher to a mug, the poured beer, etc., taps the liquid level of the beer, etc. inside the mug. If the beer is full of foam, or if the momentum of pouring from the pitcher to the mug is too weak, the beer may not be sufficiently foamy. As described above, there is a problem that it is very difficult to generate an appropriate amount of creamy foam in a mug or the like.

  Also, when pouring beer into individual mugs, etc. from portable containers such as cans and bottles in addition to pitchers in outdoor resorts and homes other than beer halls, creamy foam is also generated as described above. There was a problem that it was difficult to generate an appropriate amount.

  The present invention is for solving the above-described problems, and adds an appropriate amount of creamy foam to a sparkling beverage poured from a portable container into a mug or the like without requiring skill. An object of the present invention is to provide a pouring device that can be used.

  A first characteristic configuration of the dispensing device according to the present invention is a dispensing device that is attached to a portable container and that dispenses an effervescent beverage contained in the portable container, and is contained in the portable container. An intake port for taking in the sparkling beverage, a spout for pouring out the sparkling beverage taken in from the intake port, a flow path for communicating the intake port and the spout, and A flow state changing mechanism that changes the flow state of the sparkling beverage flowing through the flow path to at least the first pouring state or the second pouring state, and the sparkling beverage flowing through the flow path A vibration mechanism that imparts vibration, and the vibration mechanism is activated when the second dispensing state is established.

  When vibration is imparted to the sparkling beverage by the vibration mechanism, bubbles are generated by the dissolved carbon dioxide gas. When the flow state of the sparkling beverage is in the first pouring state by the flow state changing mechanism, the vibration mechanism does not give vibration without suppressing the generation of foam, and when it is in the second pouring state, the vibration mechanism By applying vibration to the sparkling beverage flowing through the flow path, fine foam can be generated. Accordingly, an appropriate amount of creamy foam can be added without requiring skill.

  The second characteristic configuration is configured such that an effervescent beverage is poured out from the pouring outlet by making the portable container into an inclined pouring posture, and the flow state changing mechanism is The dispensing amount of the sparkling beverage dispensed from the dispensing outlet is configured to be quantitative or changeable to a small amount, and the first dispensing state is a state when the dispensing amount is quantitative, and the second dispensing The dispensing state is a state when the dispensing amount is small.

  When you want to pour a sparkling beverage into a mug or the like, you can quickly dispense by securing a predetermined flow rate with the amount of sparkling beverage poured out from the spout by the flow state changing mechanism as a fixed amount. . On the other hand, when it is desired to pour bubbles into a mug or the like, the amount of pour can be reduced by the flow state changing mechanism, and bubbles can be generated in that state. That is, since the amount dispensed is small, there is no possibility of excessive foam generation. Therefore, an appropriate amount of foam can be easily poured into a mug or the like without requiring skill.

  In the third characteristic configuration, the flow path is composed of a plurality of flow pipes that connect the intake port and the spout port provided at least one by one, and the flow state changing mechanism includes: By closing at least one of the plurality of flow pipes, the dispensing amount is configured to be changed from a fixed amount to a small amount, and the vibration exciter is configured of the plurality of flow pipes. It is in the point which gives a vibration with respect to the sparkling beverage which flows through the other flow pipe which is not obstruct | occluded.

  With a simple configuration in which a plurality of flow pipes are prepared and at least one of them is closed, it is possible to easily change the dispensing amount.

  The fourth characteristic configuration is that, among the plurality of flow pipes, the total flow path cross-sectional area of the flow pipe to be closed by the flow state changing mechanism is the total flow path cross-sectional area of another flow pipe. It is in the point set larger than.

  The flow pipe to be blocked is a flow path for the sparkling beverage. Accordingly, by setting the total flow path cross-sectional area of the flow path to be larger than the total flow path cross-sectional area of the flow pipe that is not the blockage target, it is possible to sufficiently secure the amount of the sparkling beverage dispensed. A flow pipe that is not a block target is a flow path of the sparkling beverage for generating foam. Therefore, by setting the total flow path cross-sectional area of the flow path to be smaller than the total flow path cross-sectional area of the flow pipe to be blocked, it is possible to reliably generate bubbles in the flow pipe and to reduce the amount of bubbles generated. It can be an appropriate amount.

  In the fifth characteristic configuration, among the plurality of flow pipes, the flow pipe to be closed by the flow state changing mechanism is configured such that when the portable container is in the pouring posture, It exists in the point arrange | positioned in the position which becomes relatively lower than a flow-through pipe.

  When a sparkling beverage is poured into a mug or the like, the possibility that excess foam generated in the portable container is poured out together with the sparkling beverage is reduced.

  In the sixth characteristic configuration, the flow path includes at least one flow pipe that communicates the intake port and the spout provided at least one, and the flow state changing mechanism includes: The pouring amount is changed from a fixed amount to a small amount by reducing the cross-sectional area of the flow passage of the flow pipe, and the vibration exciter is applied to the sparkling beverage flowing through the flow pipe. In contrast, vibration is applied.

  When you want to pour a sparkling beverage into a mug or the like, you can quickly dispense by securing a predetermined flow rate with the amount of sparkling beverage poured out from the spout by the flow state changing mechanism as a fixed amount. . On the other hand, when it is desired to pour bubbles into a mug or the like, the amount of pour can be reduced by the flow state changing mechanism, and bubbles can be generated in that state. That is, since the amount dispensed is small, there is no possibility of excessive foam generation. Therefore, an appropriate amount of foam can be easily poured into a mug or the like without requiring skill.

  In the seventh characteristic configuration, the flow state changing mechanism includes an operation unit, a movable unit, and a flexible tube disposed in at least a part of the flow tube. In conjunction with the operation of the operation unit, the tube is pressed and deformed, and the activation switch of the vibration mechanism is turned on.

  In the ninth characteristic configuration, the flow state changing mechanism includes a position holding mechanism that holds the movable portion at a predetermined movable position, and the position holding mechanism has the movable portion held at the movable position. When the operation unit is operated when there is not, the movable unit is held at the movable position to maintain a small amount of extraction, and the operation unit is operated when the movable unit is held at the movable position. Is operated, the holding is released, and the amount of extraction is maintained at a fixed amount.

  By providing the position holding mechanism, the flow rate of the sparkling beverage flowing through the flow path is maintained at a small amount without continuing to operate the operation unit. When the operation unit is operated again, the state where the flow rate is small is cancelled.

  The tenth characteristic configuration is that the vibration mechanism stops when the amount of extraction is changed from a small amount to a fixed amount by the flow state changing mechanism.

  The vibration mechanism can be stopped along with the operation of stopping the dispensing of the sparkling beverage.

  The eleventh characteristic configuration includes a gas supply mechanism for supplying gas into the portable container, and the internal pressure of the portable container is increased by the gas supplied by the gas supply mechanism, thereby The sparkling beverage is configured to be poured out, and the spout includes a first spout and a second spout, and the flow path includes the intake and the first spout. And a second flow path that communicates the intake port and the second outlet, and the flow state changing mechanism includes the first flow path or the second flow path. A flow path can be selected. The first extraction state is a state in which the first flow path is selected. In the second extraction state, the second flow path is selected. It is in a state that

  When the first flow path is selected by the flow state change mechanism, vibration is not applied by the vibration mechanism to suppress the generation of bubbles, and when the second flow path is selected, the vibration mechanism causes the flow to pass. Fine bubbles can be produced by applying vibration to the sparkling beverage flowing through the flow path. By preparing a suitable flow path for each of the sparkling beverage and foam, it is possible to dispense appropriately.

  The twelfth characteristic configuration is that the channel cross-sectional area of the first flow path is set larger than the flow path cross-sectional area of the second flow path.

  When pouring sparkling beverages into mugs, etc., the amount of sparkling beverage dispensed from the spout is quantified by selecting the first flow path with a large channel cross-sectional area by the flow condition changing mechanism. As a result, a predetermined flow rate can be secured and quick dispensing can be performed. On the other hand, when you want to pour foam into a mug, etc., select the second flow path with a small cross-sectional area of the flow path by the flow condition change mechanism, so that the amount of pour is reduced and bubbles are generated in that state. Can be made. That is, since the amount dispensed is small, there is no possibility of excessive foam generation. Therefore, an appropriate amount of foam can be easily poured into a mug or the like without requiring skill.

  The thirteenth characteristic configuration includes a discharge path for discharging the gas supplied to the portable container, and the flow state changing mechanism includes both the first flow path and the second flow path. The release path is opened when not selected.

  When neither a sparkling beverage nor foam is poured out into a mug or the like, the gas supplied to the portable container is released, and the internal pressurized state is released, so that the sparkling beverage or foam is unexpectedly released. Is prevented from being poured out from the spout through the first flow path or the second flow path.

  The fourteenth characteristic configuration is that the vibration generating mechanism is an ultrasonic wave generating means, and the ultrasonic wave generating means vibrates to the sparkling beverage flowing through the flow path through the flow path by ultrasonic waves. It is in the point which gives.

  The texture of the bubbles generated by the vibration of the ultrasonic wave derived from the ultrasonic wave generation means can be made fine.

  The fifteenth characteristic configuration lies in that an adjustment unit for the vibration frequency and vibration amplitude of the ultrasonic wave generating means is provided.

  By changing the vibration frequency and vibration amplitude by the adjustment unit, the state of the bubble to be poured out can be freely adjusted. Since the state of the generated foam varies depending on the state and type of the sparkling beverage, such as the temperature, and the brand, a plurality of optimum settings may be stored for each sparkling beverage stored in the portable container.

Then, the pressing portion 60 cooperates with the pressure receiving portion 59 on the main body portion 31 side to deform the tube constituting the beer flow tube 44, and the beer flow tube 44 is closed. The position when the movable bar 57 is moved to the beer flow pipe 44 side against the elastic force of the compression spring 63 is referred to as a “pressing position”.

  Thus, when the beer flow pipe 44 is closed, the beer of the pitcher 10 can be poured out only from the dual-purpose flow pipe 45. In this manner, the flow rate changing mechanism 50 changes the amount of beer poured out from the spout 43 from a fixed amount to a small amount by closing at least one of the plurality of flow tubes.

  When the user releases the operation lever 54, that is, when the pressing portion 55 is stopped, the movable bar 57 is moved from the pressing position and returned to the initial position by the elastic force of the compression spring 63 and the elastic force of the tube itself, The block of the beer flow pipe 44 in the flow path 40 is released, and the amount of beer poured out from the spout 43 is changed from a small amount to a fixed amount. That is, in this embodiment, the flow rate changing mechanism 50 constitutes a flow state changing mechanism for changing the flow state of beer flowing through the flow path 40 to at least the first or second discharge state, and the beer The state where the flow-through pipe 44 is not closed constitutes the first extraction state, and the state where the flow-through pipe 44 for beer is closed constitutes the second extraction state.

  The movable bar 57 further includes an interlocking portion 64 that is formed to extend upward between the pressing portion 60 and the contact portion 61. The interlocking unit 64 moves as the movable bar 57 slides, and turns on / off an activation switch 75 of the ultrasonic generator 72 described later.

That is, in this embodiment, the flow rate changing mechanism 50 configures a flow state changing mechanism that changes the flow state of beer flowing through the flow path 80 to at least the first or second discharge state. The state where the flow path 80 is not deformed constitutes the first extraction state, and the state where the flow path 80 is deformed constitutes the second extraction state.

  The vibration surface 77 of the ultrasonic generator 72 is disposed so that one end portion of the flow path 80 is in contact with the piping portion 84 constituting the spout 82. In conjunction with the deformation of the tube 83 so that the cross-sectional area of the flow path is reduced by the operation of the operation lever 54, the interlocking portion 64 of the movable bar 57 turns on the start switch 75, and the drive circuit generates ultrasonic waves. The pipe 72 is started and the piping part 84 is vibrated. When the beer passes through the pipe portion 84, vibration is imparted and foaming is excited, and the beer is poured into a jug or the like from the spout 82 as creamy foam. When a desired amount of foam is poured into the mug or the like, the user releases the thumb from the pressing portion 55 while returning the pitcher 10 from the pouring posture to the steady posture. As described above, an appropriate amount of creamy foam can be added to beer poured from the pitcher 10 into a mug or the like without requiring skill. The vibration surface 77 is not limited to the configuration in contact with the piping portion 84, and is configured to contact the tube 83 to vibrate the tube 83 and to impart vibration to the beer flowing through the tube 83 to cause foaming.
