Description

  This invention relates to a small beverage dispenser that replenishes and stores beverages from a commercial beverage server, etc., can be carried to a table of a restaurant, etc., and can be distributed to each restaurant on the table. The present invention relates to a beverage dispenser capable of safely and reliably releasing the pressurized gas inside when removing the outer lid.

  In restaurants, etc., to provide beverages such as draft beer to customers who eat and drink, drinks are poured into glasses etc. from commercial beverage servers, etc. provided in restaurants, etc. It was common for humans to carry to the table of each person who ordered a drink. However, it is quite difficult to carry a large number of glasses and the like to the table of the person who eats and drinks according to the order of each person. In addition, when the store is crowded, not only is it difficult to transport such glasses, but there is also a risk of dropping or spilling the beverage being transported, which may cause problems with customers. is there.

  In order to reduce the frequency of transporting beverages and the like in the store, a large container with a handle called a pitcher is also used. A drink is accommodated in a large pitcher and carried to a table of the eating and drinking, and each eating and drinking pours out from the pitcher into his own glass and the like for drinking. Conventional pitchers have been made of glass or resin. Glass was heavy and had a problem in handling. Even if it was made of resin, it was quite heavy when the beverage entered, so a considerable amount of force was required to pour the beverage into the glass. In terms of heat retaining properties, some resin-made double containers have improved heat retaining properties. However, since the upper part was open | released in all, the heat insulation / cold insulation effect was limited. Moreover, since the upper part was open in both cases, outgassing of the sparkling beverage was inevitable.

  In order to reduce the frequency of transporting such beverages, it is conceivable to use a small beverage server or beverage dispenser that can be placed on a table and used. As a beverage dispensing device that can be used by being placed on a table, a device as disclosed in Patent Document 1 is known. Patent Document 1 describes a beverage dispensing apparatus that uses a can container such as a 2-3 liter canned beer. In this beverage dispensing device, the inside of the can container is pressurized by an electric pump so that the beverage inside the container is poured out.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side view showing the overall configuration of a beverage dispenser 1 of the present invention. FIG. 2 is a front view showing the overall configuration of the beverage dispenser 1, and FIG. 3 is a plan view of the beverage dispenser 1 as viewed from above. The beverage dispenser 1 is a small beverage dispenser capable of dispensing a beverage on a table such as a table of a restaurant in a restaurant or the like. Since the beverage can be poured out and distributed from the beverage dispenser 1 to the glass of each restaurant, the frequency of transporting the beverage can be greatly reduced, and the beverage is efficiently provided to each restaurant. be able to.

  Moreover, the part which accommodates the drink of the drink dispenser 1 becomes a sealed vacuum heat insulation container, and can maintain the temperature of the accommodated drink at a suitable temperature for a long time. Moreover, since it is a sealed container, it is difficult for carbon dioxide gas to escape from the beverage even if it contains a sparkling beverage such as draft beer.

  The beverage dispenser 1 includes a dispenser body 11 and an outer lid 14. The outer lid 14 is detachably fixed to the dispenser body 11. The procedure for removing the outer lid 14 will be described in detail later. The dispenser body 11 includes a vacuum heat insulating container 12. In the vacuum heat insulating container 12, the wall surface constituting the container is a double wall, and the middle part of the double wall is in a sufficiently low pressure state. The vacuum heat insulating container 12 is excellent in heat retaining properties, and can maintain the temperature of the beverage at an appropriate temperature for a long time even when a beverage in an appropriate temperature state is accommodated. The vacuum heat insulating container 12 is a substantially cylindrical container and is made of a stainless material.

  A handle 111 is fixed behind the dispenser body 11. By holding the handle 111 by hand, the entire beverage dispenser 1 can be easily transported. The beverage dispenser 1 can pour out and store a beverage at an appropriate temperature from a commercial beverage server in a restaurant. Since the beverage poured out from the commercial beverage server can be used as it is, it is possible to efficiently cool the beer beverage and the like, for example, it is not necessary to separately cool the beer beverage in another container. The beverage dispenser 1 containing the beverage can carry the handle 111 as it is to the table of the restaurant. Since the beverage is contained in a sealed state, the beverage is not spilled.

  A spout 16 is provided in the upper front portion of the dispenser body 11. Further, a dispensing lever 15 protrudes from the top of the beverage dispenser 1. This beverage dispenser 1 is optimized for beer beverages such as draft beer. The outlet 16 is connected to a down tube 131, which will be described later, by a flow path hose made of a soft material (not shown). Will not be poured out. By operating the dispensing lever 15 forward or backward, the closing of the flow path hose by the dispensing lever 15 is released, and the dispensing port 16 and the down tube 131 are communicated.

  In this embodiment, when the pouring lever 15 is operated so as to be tilted forward, a beer beverage substantially free of bubbles is poured out from the pouring port 16. When the pouring lever 15 is operated so as to be tilted backward, the beer beverage with almost only foam is poured out from the pouring port 16. In addition, as a structure for foaming a beer beverage, a structure using an ultrasonic wave or a structure using an orifice principle is known. When each food / beverage person pours beer drinks etc. into a glass etc., the ratio of foam and liquid parts, such as beer drinks, can be made into an optimal state by adjusting each pouring amount.

  Thus, since the property of the beverage poured out from the spout 16 can be switched by the operation direction of the dispensing lever 15, the amount of foam of beer beverage or the like can be adjusted to an optimum state. In addition, as shown in FIG. 2, the spout 16 is provided with two spouts on the left and right, and a beer beverage almost free of bubbles is poured out from the spout on the right side. From there, beer drinks with almost only foam are poured out.

  A tray portion 112 is disposed at the lower front portion of the dispenser body 11. An elliptical concave portion is formed on the upper surface of the tray portion 112. The beverage dripped or dropped from the spout 16 does not accumulate in this recess and flow out to the surroundings.

  As shown in FIG. 3, an operation unit 1412 and a safety button 143 that are used when the outer lid 14 is removed are disposed on the top of the beverage dispenser 1. The functions of these configurations and the procedure for removing the outer lid 14 will be described in detail later.

  FIG. 4 is a cross-sectional view showing the internal configuration of the beverage dispenser 1. Note that the handle 111 and the tray portion 112 are indicated by dotted lines. A dispenser main body 11 is connected to an open portion at the upper end of the vacuum heat insulating container 12, and a dispensing lid 13 is attached to the open portion of the dispenser main body 11. The vacuum heat insulating container 12 and the dispenser body 11 and the dispenser body 11 and the dispensing lid 13 are sealed with a sealing member or the like so as to be in a sealed state. Thereby, the vacuum heat insulating container 12 is a sealed container.

  The dispensing lid 13 is provided with a down tube 131. The beverage inside the vacuum insulation container 12 is poured out through the down tube 131. A pressure pump 144 and a battery 145 for driving the pressure pump 144 are disposed inside the outer lid 14. By driving the pressurizing pump 144, external air can be pressurized and sent to the inside of the vacuum heat insulating container 12, the pressure inside the container can be increased, and the beverage can be poured out through the down tube 131.

  When the outer lid 14 is attached to the dispenser main body 11, the pressurized gas supply port 1441 of the pressurized pump 144 and the pressurized gas passage 133 provided in the dispensing lid 13 are connected in an airtight state. . The pressurized gas pressurized by the pressurized pump 144 is sent from the pressurized gas supply port 1441 through the pressurized gas passage 133 to the inside of the vacuum heat insulating container 12. Here, the pressure pump 144 and the battery 145 are arranged on the outer lid 14, but they can be arranged not on the outer lid 14 but on the dispensing lid 13, and inside the dispenser main body 11. It can also be arranged.

  The pressurizing pump 144 is driven by the operation of the dispensing lever 15. When the dispensing lever 15 is tilted forward or backward, the driving of the pressure pump 144 is started, and when the dispensing lever 15 is returned to the upright state, the driving of the pressure pump 144 is stopped. That is, the pressurizing pump 144 is driven by tilting the extraction lever 15 forward or backward, pressurizing external air, and passing through the pressurized gas passage 133 from the pressurized gas supply port 1441 to It is sent to the inside and the pressure inside the container is increased to guide the beverage from the down tube 131 to the flow path hose.

  Further, by closing the pouring lever 15 forward or backward, the closing of the flow path hose is released and the pouring port 16 and the down tube 131 communicate with each other, so that a beverage can be poured from the pouring port 16. When the dispensing lever 15 is returned to the upright state, the driving of the pressurizing pump 144 is stopped and the flow path hose is closed to stop the dispensing of the beverage. At this time, the vacuum heat insulating container 12 is in a sealed state.

  In addition, a check valve is provided in the pressurized gas passage 133 from the pressurizing pump 144 to the vacuum heat insulating container 12, and even if the pressurizing pump 144 stops, the pressurized gas inside the container flows backward through the passage. It is not released to the outside. That is, if the inside of the vacuum heat insulating container 12 becomes a high pressure state, the high pressure state is maintained for a long time.

  The dispensing lid 13 is provided with an internal pressure release valve 132 for releasing the pressurized gas inside the vacuum heat insulating container 12 to the outside. Since the inside of the vacuum heat insulating container 12 is maintained in a high pressure state, there is a problem in removing the outer lid 14 in that state. That is, when the outer lid 14 is removed in a high pressure state, the dispensing lid 13 is raised by the internal pressure, and the beverage is blown out from the gap generated thereby and scattered around, or the dispensing lid 13 is ejected. There is a fear.

  Therefore, before removing the outer lid 14 from the beverage dispenser 1, it is necessary to release the pressurized gas inside the vacuum heat insulating container 12 to the outside. A safety button 143 provided on the outer lid 14 is a safety mechanism provided for that purpose. When the safety button 143 is pressed downward, the internal pressure release valve 132 can be opened to release the pressurized gas inside the container to the outside. The safety button 143 is biased upward by an elastic member, and the internal pressure release valve 132 is biased in the closing direction (upward) by the elastic member. Therefore, the internal pressure release valve 132 is closed during normal use.

  A rotating member 141 is rotatably provided on the outer lid 14. A fixing claw 1411 is formed at the lower end portion of the rotating member 141, and the fixing claw 1411 engages with the protruding portion of the dispenser main body 11 to fix the outer lid 14 to the dispenser main body 11. The rotating member 141 is urged by an elastic member (not shown) in a direction in which the fixed claw 1411 is engaged with the protruding portion. The outer lid 14 and the dispenser main body 11 are fixed to each other by the engagement of the engaging portion on the front side of the dispenser main body 11 and the fixing claw 1411 on the rear side.

  An operation unit 1412 is provided on the upper end side of the rotating member 141. By pulling up the operation unit 1412 upward, the engagement of the fixed claw 1411 can be released and the outer lid 14 can be removed from the dispenser body 11. In order to operate the operation unit 1412, it is necessary to push the safety button 143 downward before that.

  When the safety button 143 is pushed downward, a finger can be inserted through a gap formed between the upper surface of the safety button 143 and the operation unit 1412 and the operation unit 1412 can be pulled upward. When the safety button 143 is not pushed downward, the operation unit 1412 cannot be pulled upward. With such a configuration, when the outer lid 14 is removed, the pressurized gas inside the vacuum heat insulating container 12 is always released to the outside, and the outer lid 14 can be safely removed.

  Next, a procedure for removing the outer lid 14 will be described with reference to the drawings. When the outer lid 14 is removed, first, the dispensing lever 15 is removed as shown in FIG. The dispensing lever 15 has a structure that can be easily removed from the base. Then, the safety button 143 is pushed downward. At this time, the lower end of the safety button 143 opens the internal pressure release valve 132 to release the pressurized gas inside the container to the outside.

  Next, as shown in FIG. 6, a finger is inserted through a gap formed between the upper surface of the safety button 143 and the operation unit 1412, and the operation unit 1412 is pulled up. Then, the rotation member 141 rotates in the disengagement direction, and the fixed claw 1411 at the lower end of the rotation member 141 is disengaged from the protruding portion. In this state, the outer lid 14 can be removed from the dispenser body 11.

  Next, as shown in FIG. 7, the rear end side of the outer lid 14 is pulled up from the dispenser body 11. Thereby, it becomes possible to remove the engaging part of the dispenser main body 11 front side. Then, the engaging portion on the front side of the dispenser body 11 is removed, and the entire outer lid 14 is pulled away from the dispenser body 11 as shown in FIG. The outer lid 14 can be removed from the dispenser body 11 by the above procedure. As described above, when the outer lid 14 is removed, the pressurized gas inside the vacuum heat insulating container 12 is always released to the outside, and the outer lid 14 can be safely removed. If the outer lid 14 is removed, the dispensing lid 13 can be further removed, and the vacuum insulation container 12 can be replenished with a new beverage, and the inside of the container can be cleaned.

  In order to attach the outer lid 14 to the dispenser body 11, the outer lid 14 and the engaging portion on the front side of the dispenser body 11 are first engaged, and then the rear side of the outer lid 14 is engaged with the dispenser body 11. At the start of use of the beverage dispenser 1, the outer lid 14 is removed from the dispenser body 11, and then the dispensing lid 13 is removed to accommodate the beverage inside the vacuum heat insulating container 12. Then, the dispensing lid 13 is attached to the open portion of the dispenser body 11, and then the outer lid 14 is attached to the dispenser body 11. Thus, the beverage dispenser 1 can be used.
