The via barrel 30 shown in FIG. 2 has a cylindrical rubber member fixed to the upper and lower portions, and a handle portion 30a is formed in the circumferential direction on the upper rubber member. A dispensing head 31 for connecting the gas hose H2 and the beer hose H3 is attached to the outlet of the via barrel 30. The dispense head 31 opens and closes the flow path of beer from the beer barrel 30 to the beer hose H3 by operating the lever 31a.

  As shown in FIGS. 2 and 5, the carbon dioxide supply device 40 supplies carbon dioxide by sublimating dry ice. The carbon dioxide supply device 40 includes a dry ice container 41 that encloses dry ice. The dry ice container 41 includes a stainless steel container portion 41a having a bottomed cylindrical shape for containing dry ice, and a stainless steel lid portion 41c that closes the upper surface opening of the container portion 41a. In the dry ice container 41, the upper end surface of the container part 41a is covered with a lid part 41c via a packing member, and is sealed by being pressed against the container part 41a by two fasteners 41d using the lid part 41c as a fastening metal fitting. Yes. In the present embodiment, the capacity of the dry ice container 41 is 1.7L.

  The dry ice container 41 has a substantially rectangular parallelepiped shape in which a large rounded portion is formed at each corner, and the rear surface, which is the opposite surface of the via barrel 30, is shaped along the outer peripheral surface of the via barrel 30. It has a substantially arc shape that protrudes rearward so that the center part is recessed forward. The upper end edge (upper end portion) of the container portion 41a is formed with a flange portion 41b protruding in the horizontal direction, and the lid portion 41c has the same size as the flange portion 41b. As shown in FIG. 6, the dry ice container 41 has a container part 41a (a container part 41a (a lower part of the container part 41a) protruding from the container part 41a (the lower part of the container part 41b). The lower portion of the flange portion 41 b of the heel portion 41 b is not in direct contact with the via barrel 30 due to a gap O generated between the via barrel 30. Thereby, the beer in the beer barrel 30 is not frozen by the dry ice in the container part 41a. In the dry ice container 41, the flange portion 41b and the lid portion 41c of the container portion 41a protrude from the container portion 41a (the lower portion from the flange portion 41b) to the via barrel 30 side. The same effect can be obtained even if the is protruded to the via barrel 30 side.

  The dry ice container 41 includes a delivery connector (sending part) 42 for sending carbon dioxide gas to the lid part 41c, a recoverable safety device 43, and a non-recoverable safety device 44. The connector 42 for sending out is for sending the carbon dioxide gas which arises from the dry ice accommodated in the container part 41a, and is connected to the via barrel 30 by gas hose H1, H2. Between the gas hoses H1 and H2, a pressure reducing valve 32 for reducing the pressure of the carbon dioxide gas fed into the via barrel 30 to 80 kPa as a predetermined pressure is attached.

  The recoverable safety device 43 includes a safety valve and is attached to an attachment hole formed in the lid portion 41c. When the pressure in the dry ice container 41 exceeds 160 kPa as a predetermined pressure by the biasing force of the spring member, the recoverable safety device 43 releases the carbon dioxide gas by opening the valve unit against the biasing force of the spring member. The inside of the dry ice container 41 does not exceed 160 kPa. According to the provisions of the Aviation Law Enforcement Regulation, the internal pressure of the dry ice container 41 must not exceed 200 kPa. However, the internal pressure of the dry ice container 41 should not exceed 160 kPa as a pressure lower than 200 kPa by the recoverable safety device 43. Therefore, even if it is instantaneous, it does not exceed 200 kPa, and it is possible to make the dry ice container 41 safer and mountable on a passenger aircraft. Even if the set pressure of the recoverable safety device 43 does not exceed 200 kPa, the dry ice container 41 can be similarly mounted on the passenger aircraft.

  The non-recoverable safety device 44 uses a rupturable plate 44c that bursts when the predetermined pressure exceeds 200 kPa, so that the pressure in the dry ice container 41 does not exceed 200 kPa. As shown in FIG. 7, the non-recoverable safety device 44 includes a substantially cylindrical holder 44a fixed to a mounting hole formed in the lid portion 41c, and a silicon-type annular packing member 44b above the holder 44a. A round aluminum rupture plate 44c placed on the rupture plate 44c, a washer 44d placed above the rupture plate 44c, and a male screw formed on the outer periphery of the holder 44a to screw the rupture plate 44c into the holder 44a. And a nut 44e for fixing to the nut. As described above, in the provisions of the Aviation Law Enforcement Regulation, it is necessary to prevent the internal pressure of the dry ice container 41 from exceeding 200 kPa, but the internal pressure of the dry ice container 41 does not exceed 200 kPa even in the non-recoverable safety device 44. Thus, the dry ice container 41 can be made safer and mountable on a passenger aircraft.

  When dry ice is accommodated in the dry ice container 41, the internal pressure of the dry ice container 41 increases as the dry ice becomes carbon dioxide. When the internal pressure of the dry ice container 41 exceeds 160 kPa, the safety valve that is the recoverable safety device 43 is temporarily opened to discharge carbon dioxide gas, and the internal pressure of the dry ice container 41 does not exceed 160 kPa. Further, when the safety valve which is the recoverable safety device 43 is not activated due to a failure or the like, and the internal pressure of the dry ice container 41 exceeds 200 kPa from 160 kPa, the rupture disc 44c of the non-recoverable safety device 44 is ruptured and carbon dioxide gas is generated. It is discharged and the internal pressure of the dry ice container 41 does not exceed 200 kPa. As described above, in the carbon dioxide supply device 40, safety devices having two different mechanisms for suppressing an increase in pressure are provided, such as a recoverable safety device 43 including a safety valve and a non-recoverable safety device 44 having a rupturable plate 44c. Since it is used, the pressure in the dry ice container 41 can be reliably prevented from exceeding 200 kPa as compared with the one provided with two safety devices having the same mechanism.

  As shown in FIG. 8, the hand draft (draft) 50 is a hand-held draft for pouring beer delivered from the beer barrel 30 through the beer hose H3 into the cup. The hand draft 50 has a cylindrical main body 51 having a valve mechanism in an inner hole through which beer passes, and a pouring hole integrally formed on the peripheral wall of the main body 51 and communicating with the inner hole. The nozzle 52, the grip 53 connected to the lower part of the main body 51, an operation lever 54 for operating the valve mechanism, and a cap 55 covering the spout of the spout nozzle 52 are provided.

  The operation lever 54 includes an arm portion 54a connected to the valve mechanism portion and a lever portion 54b that rotates the arm portion 54a to operate the valve mechanism portion. The operation lever 54 extends an arm portion 54a fixed to the valve mechanism portion with a screw 54c on the opposite side of the pouring nozzle 52 of the main body portion 51 to the pouring nozzle 52 side, and the lever portion 54b extends from the distal end portion of the arm portion 54a. Is extended downward along the grip 53. When the operation lever 54 is not operated, the hand draft 50 is configured such that the valve mechanism portion is closed by the biasing force of the built-in spring. When the lever portion 54b of the operation lever 54 is tilted toward the grip 53, the hand draft 50 is built-in. The valve mechanism portion is opened against the urging force of the spring, and the beer passing through the inner hole flows into the pouring hole and is poured out from the pouring nozzle 52.

  The cap 55 is attached to the tip end portion of the dispensing nozzle 52 so as to be detachable and rotatable. The cap 55 includes a bottomed cylindrical main body portion 55a that covers the distal end portion of the dispensing nozzle 52, and a lock portion 55b that is integrally formed on the lower outer periphery of the main body portion 55a and restricts the tilting of the operation lever 54. ing. When the hand draft 50 is not used, as shown in FIG. 8, the main body portion 55 a of the cap 55 is fitted to the dispensing nozzle 52, and the lock portion 55 b is locked to the grip 53 side of the lever portion 54 b of the operation lever 54. Then, the tilting of the operation lever 54 can be restricted. When the cap 55 is rotated clockwise (for example, 90 °) shown in FIG. 8A from this state, the lock portion 55b is not locked to the grip 53 side of the lever portion 54b of the operation lever 54, and the cap 55 is moved. It can be removed, and the operation lever 54 can be tilted. As described above, when the cap 55 is attached to the dispensing nozzle 52 when the hand draft 50 is not used and the lock portion 55b is locked to the lever portion 54b of the operation lever 54, a force for erroneously tilting the operation lever 54 is generated. However, it is possible to prevent beer from being poured out from the pouring nozzle 52. Further, if the lock portion 55b of the cap 55 is locked to the grip 53 side of the lever portion 54b of the operation lever 54, the cap 55 does not come off the dropping nozzle 52 even if there is vibration. Further, when the hand draft 50 is used, it is also possible to temporarily place the main body portion 55 a by fitting it with the fixing screw 54 c of the operation lever 54 after removing the cap 55 from the pouring nozzle 52.

Moreover, the lever 31a of the dispensing head 31 is operated from the opening 17a of the partition plate 17, and the flow path of beer is opened. The beer hose H3 connected to the dispensing head 31 is led out upward from the opening 17a of the partition plate 17 and wound around the opening 17a and is housed in the inner lid housing part 15 together with the hand draft 50. 18 is placed on the upper side of the inner lid housing 15.

  Thus, the beer dispenser 10 which accommodated the beer barrel 30, the carbon dioxide supply device 40, and the hand draft 50 in the housing | casing 11, and made the state which connected gas hose H1, H2 and beer hose H3 suitably in FIG. As shown, it is stored in a cart 60 and transported to the airport. The beer dispenser 10 accommodated in the cart 60 is loaded into a passenger plane and used to provide beer to passengers.

  When beer is provided to passengers using the beer dispenser 10 in the passenger plane, as shown in FIG. 9, the front door of the cart 60 is opened to open the front, the top cover 18 is removed, and the drain 21 is attached using the mounting bracket 21. The tank 20 is attached to the front surface of the housing 11. As shown in FIG. 10, the drain tank 20 may be fixedly attached to a drawer 61 called a drawer provided on the upper portion of the cart 60 by the mounting bracket 21. The hand draft 50 is taken out of the housing 11 through the notch 16a of the inner lid housing part 15 through the beer hose H3, and is fixed to the notch 20b of the tongue 20a of the drain tank 20 by being locked. Since the hand draft 50 and the beer hose H3 are housed in the inner lid housing portion 15 until they are taken out from the housing 11, they are cooled by the dry ice container 41 and the dry ice D for cold storage during transport, like the beer barrel 30. Has been. Thereby, the beer poured out from the hand draft 50 can be prevented from being heated when passing through the beer hose H3 and the hand draft 50.

  When providing beer to a passenger, the cart 60 is moved to the vicinity of the passenger, the hand draft 50 is removed from the drain tank 20, the cap 55 of the hand draft 50 is removed from the dispensing nozzle 52, and the beer is placed in the cup. Pour out. When the beer has been poured out, the hand draft 50 is again locked in the notch 20b of the drain tank 20 and fixed. At this time, since the pouring nozzle 52 of the hand draft 50 is on the upper side of the drain tank 20, the beer spilled from the pouring nozzle 52 falls into the drain tank 20, so that the floor surface can be prevented from being soiled.

  When this beer dispenser 10 is used on a domestic passenger plane in Japan, as with other food and drink, it takes 2 hours to transport from the catering company to the airport, and 3 hours as the maximum time for the passenger plane to fly to its destination. Must be available for a total of 5 hours or more. In the beer dispenser 10 described above, when 1.2 kg of dry ice is put into the dry ice container 41 of the carbon dioxide supply device 40, the internal pressure of the dry ice container 41 rises to 160 kPa in about 5 minutes, and the carbon dioxide is delivered. Otherwise, this pressure was maintained for about 10 hours. Even when beer was poured out using the beer dispenser 10, the internal pressure of the dry ice container 41 was maintained at 160 kPa for 5 hours or more. Further, even under severe conditions of 35 ° C., the internal pressure of the dry ice container 41 was maintained at 160 kPa for 5 hours or more. At this time, the via barrel 30 was sufficiently cooled by the cold heat of the dry ice container 41.

  The above 1.2 kg of dry ice can maintain a pressure of 160 kPa at which the internal pressure of the dry ice container 41 can pump beer, and can sufficiently cool the via barrel 30, for a total of 5 hours of transportation time to the airport and flight time. The dry ice container 41 has a volume that can accommodate 1.2 kg of dry ice. Further, since the dry ice container 41 can be replenished with dry ice by opening and closing the lid portion 41c, if the dry ice container 41 is replenished with dry ice after the passenger aircraft arrives at the destination, it is necessary for the return path. The internal pressure of the dry ice container 41 is maintained at 160 kPa according to time, and the via barrel 30 can be sufficiently cooled.

  As described above, the carbon dioxide supply device 40 used in the beer dispenser 10 has a relatively low pressure generated by sublimation of dry ice in the dry ice container 41 without using high-pressure carbon dioxide such as a gas cartridge or a carbon dioxide cylinder. The dry ice container 41 has a recoverable safety device 43 comprising a safety valve that discharges carbon dioxide gas when exceeding 160 kPa, and a rupture plate 44c that bursts and discharges carbon dioxide when exceeding 200 kPa. Since two safety devices, the non-recoverable safety device 44, were provided, it could be installed in a passenger aircraft as a safe carbon dioxide supply device that satisfies the provisions of the Aviation Law Enforcement Regulations.

  Further, the beer dispenser 10 accommodates the dry ice container 41 and the via barrel 30 in the same casing 11, and cools the via barrel 30 by the cold heat generated from the dry ice container 41. Thereby, it is not necessary to provide a separate cooling device in the beer dispenser 10, the beer in the via barrel 30 can be cooled, the dispenser device can be downsized, and the manufacturing cost can be kept low. Further, the dry ice container 41 has a substantially arc shape in which the opposite surface facing the via barrel 30 is shaped along the outer peripheral surface of the via barrel 30 and the left and right sides protrude rearward so that the central portion is recessed forward. Therefore, it is possible to prevent the housing 11 from becoming large while ensuring a sufficient volume in the dry ice container 41.

  In the beer dispenser 10, when dry ice is sealed in the dry ice container 41, the outer surface of the dry ice container 41 becomes about −40 ° C., and when the via barrel 30 is brought into close contact with the dry ice container 41, There was a risk that the beer would freeze. However, in the dry ice container 41, the flange 41b and the lid 41c at the upper end of the container part 41a are protruded toward the via barrel 30 so that the parts other than the upper end of the dry ice container 41 are in close contact with the via barrel 30. The beer can be prevented from freezing.

In addition, since the hand draft 50 can be disposed outside the cart 60 from the opening of the front door of the cart 60, the housing 11 can be unitized and easily accommodated in the cart 60. At this time, the handle portions 12d and 12e are formed on the upper part of the front wall and the rear wall of the main body 12 of the housing 11, so that the unitized housing 11 can be easily carried. In addition, the development period can be shortened compared to the case where components are mounted on a dedicated cart, and the cost is reduced by using an existing cart 60 that meets the technical standards that can be mounted on a passenger aircraft. Can be kept low.

  Further, in the beer dispenser 10 of the present embodiment, the diameter of the via barrel 30 is smaller than the inner diameter in the left-right direction of the housing 11, but is smaller than the inner diameter in the left-right direction of the cart 60 as shown in FIG. If it is within the range, it is possible to use the via barrel 30 having a diameter larger than the inner diameter in the left-right direction of the casing 11 by protruding a part of the via barrel 30 from the U-shaped notch 12 a of the casing 11. . At this time, as shown in FIG. 11, some of the outer peripheries of the via barrel 30 are formed with an annular protrusion 30 b, but the via barrel 30 is positioned by the positioning annular step portions 12 b and 12 c of the main body 12 of the housing 11. The height of the annular protrusion 30 b is adjusted so that it does not hit the rail 60 a of the drawer 61 provided on the inner wall of the cart 60. Moreover, in this beer dispenser 10, since the reinforcement member 14 which connects the upper end part both sides of the U-shaped notch part 12a was provided in the left-right both sides wall of the main-body part 12 of the housing | casing 11, the U-shaped notch part 12a was formed. A reduction in the strength of the side walls can be suppressed.

  In the beer dispenser 10 of the present embodiment, the hand draft 50 is detachably fixed to the drain tank 20. For example, a magnet is attached to the hand draft 50 so that the hand draft 50 can be attached to and detached from the upper surface or side surface of the metal cart 60. It may be fixed to the housing 11, the cart 60 or the drawer 61 detachably by using a fixing bracket on the hand draft 50.

  In the beer dispenser 10 of the present embodiment, the inner lid accommodating portion 15 accommodates the pressure reducing valve 32 and accommodates the hand draft 50 and the beer hose H3 when not in use, and further accommodates the drain tank 20 in the inner lid. If the shape and size that can be accommodated in the portion 15 and all the accessories such as a cup for providing beer together with the drain tank 20 are accommodated in the casing 11 including the inner lid accommodating portion 15 and unitized, the beer can be obtained. As a beverage dispenser 10 ready to be dispensed, it is possible to easily manage transportation, preparatory work for beer provision and storage.
