The present embodiment has the above-described structure,
Subsequently, the operation will be described. First, a case of pouring ice cream in the ice cream dispenser will be described. The dispensing cylinder 11 is held in an upright position as shown in FIG. 1, and the solenoid valves SV1 to SV4 of the brine flow path 28 are controlled to open and close so as to form a flow path from the tank 25 to the pressure chamber 24. Have been. In order to pour out the ice cream A, a container (not shown) is placed on the mounting table 48, the lever 42 of the pour cock 41 is turned to the solid line position in FIG. Then, the pressurizing pump 29 is driven. Then, as shown by the solid arrow in FIG. 1, the brine X in the tank 25 is pumped up, supplied to the pressure chamber 24 of the pouring cylinder 11, and pressurized. As a result, the piston 13 rises to compress the pack B, the ice cream A flows out of the outlet C of the pack B, and is poured out of the spout 40 into the container. When an appropriate amount is dispensed, the dispensing cock 41
When the lever 42 is turned to the position indicated by the dashed line in FIG. 1, the microswitch 45 is turned off, and the pressurizing pump 29 is stopped.
Further, the spout 40 is closed and the pouring is stopped. again,
Ice cream A is poured out sequentially by repeating the above operation.

When the pouring operation is repeated and the ice cream A in the pack B is used up, the ice cream A is replaced with a new pack B. In that case, first, the heat insulating door 3 is opened. Then, the dispensing cylinder 11 is taken out of the refrigerator, and a pack exchange switch (not shown) is turned on, so that the brine flow path 28
The solenoid valves SV1 to SV4 are switched to the opening and closing modes opposite to the above, and the pressurizing pump 29 is driven. Then, the brine X in the pressure chamber 24 of the pouring cylinder 11 is sucked and returned into the tank 25, as indicated by the dashed arrow in FIG. As a result, the pressure in the pressure chamber 24 is inclined to a negative pressure, whereby the piston 13 descends, and the pack storage chamber 20 is greatly expanded. Then, the hooking mechanism is removed and the hinge 16 is tilted while holding the pouring cylinder 11. Along with this, the outlet C of the pack B is connected to the connection port 3 of the pouring section 35.
Extracted from 9. When the stay 17 is fully extended, the pouring cylinder 11 is held at the tilt position.
Then, after removing the lid 22, remove the outlet C with the U groove 21.
Take out the used pack B while pulling it out.

Next, a new pack B is placed in the pack storage chamber 20.
First, the cap E fitted to the outlet C is removed. The procedure is as follows. The above-described auxiliary tool 51 is prepared, and as shown in FIG.
With the handle facing downward, and holding the handle 52, and inserting the flange E2 of the cap E between the contact plate 53 and the latching plate 54. The insertion is stopped when the latching recess 57 hits the upper surface of the main body portion E1 of the cap E. At this time, as shown in FIG. Reach the department. Subsequently, the assisting tool 51
Is rotated clockwise as shown by the arrow in FIG. Then, the upper back surface of the flange E2 is hooked to the edge of the hooking recess 57, while the tip of the contact plate 53 presses the outer surface of the lower side of the flange E2, and the lever is used as a fulcrum using the pressed portion as a fulcrum. Under the action, as shown in FIG. 6, the main body E1 is gradually removed from the outlet C from the upper surface side while the cap E rotates in the same direction.

After the cap E is removed as described above, the pack B is dropped into the pack accommodating chamber 20 so that the position of the outlet C is positioned above the U-groove 21, and the flange C is bent while the outlet C is bent. The space between D1 and D2 is pushed down to the lower end of the U groove 21. Thereafter, when the lid 22 is attached and the pouring cylinder 11 is raised to the upright position, the upright position is maintained by the latch mechanism, and the tip of the outlet C of the pack B is connected to the connection port 39 of the pouring section 35. It fits inside and is connected.
Thus, the replacement of the pack B is completed, and finally, by closing the heat insulating door 3, it is possible to perform the discharging operation again.

As described above, according to the present embodiment,
By using the auxiliary tool 51, the cap E can be easily removed without requiring much force. In other words, the work of removing the cap E and the work of replacing the pack B can be performed efficiently in a short time.

<Second Embodiment> Next, a second embodiment of the present invention will be described with reference to FIGS. In the second embodiment, an auxiliary tool 61 for removing a cap is fixedly provided. Specifically, as shown in FIG. 7, on the back surface of the heat insulating door 3, the heat insulating door 3 is provided at an upper position on the side outside the pouring cylinder 11.

The receiving plate 69 has side plates 71 formed on both left and right sides of the front plate 70, and mounting plates 72 formed on the edges of the both side plates 71 are fixed to the substrate 62 by welding or the like. A receiving portion 68 having a shape is formed. This receiving part 6
8 is formed so that the lateral width gradually decreases from the upper end to the lower end.
And the width of the lower end is smaller than the diameter of the flange E2. Other structures are the same as those of the first embodiment, and portions having the same functions are denoted by the same reference numerals, and redundant description will be omitted.

In the second embodiment, the procedure for removing the cap E of the pack B is as follows. First, as shown in FIG. 7, the heat-insulating door 3 is opened, and the pack B is inserted into the outlet C of the auxiliary tool 61 under the hooking plate 64 from the front, and is lifted upward. As shown in FIG. 9, the flange E2 is inserted into the back surface of the hook plate 64 while the main body portion E1 of the cap E is fitted in the hook recess 67.

Subsequently, the pack B is rotated clockwise as indicated by the arrow in FIG. Then, the locking recess 6
The upper surface of the flange E2 is hooked on the edge of the flange 7, while the lower surface of the flange E2 hits the substrate 62, and the cap E is relatively moved by leverage with the contact portion as a fulcrum. The main body portion E1 is gradually removed from the outlet C from the upper surface side while rotating in the opposite direction. As shown in FIG. 10, when the cap E is completely removed, the cap E falls along the substrate 62 and is received by the receiving portion 68. Cap E as above
Is removed, the pack B is stored in the pack storage chamber 20 as in the first embodiment. The cap E received by the receiving portion 68 may be appropriately taken out before closing the heat insulating door 3 and disposed at a predetermined disposal place.

As in the first embodiment, the cap E can be easily removed. Further, since the auxiliary tool 61 is fixedly provided on the back surface of the heat insulating door 3, there is no need to search for each time and there is no risk of being lost. Further, since the removed cap E is once received by the receiving portion 68, it does not roll over into a strange place, and can be conveniently taken out and disposed of at an appropriate time when the hand is available. is there.
