It is maintained at such a temperature that iced confections such as ice cream can be poured out.
[0003]
When the cock 7 is opened, the valve body 8 is raised to open the cock pipe 9 and the spout switch 10 is turned on to drive the pump 11 in the machine chamber 4 in the forward direction, as indicated by a solid arrow. The brine 13 is supplied from the brine tank 12 to the pressure chamber 15 below the cylinder 14. As a result, the piston 16 ascends and the packed frozen dessert 17 loaded in the upper part of the cylinder 14 is compressed, and the frozen dessert 19 flows out from the take-out port 18 of the packed frozen dessert 17 and passes through the cock pipe 9. It is poured out from. When the cock 7 is closed, the spout switch 10 is turned off, the pump 11 is stopped, the valve body 8 is lowered, the cock pipe 9 is closed, and the extraction of the frozen dessert 19 is stopped.
[0004]
When the piston 16 reaches the top dead center position in the cylinder 14 and the frozen dessert 17 cannot be further compressed and the frozen dessert 19 cannot be dispensed, the operation of the operation panel 21 causes the pump 11 to move in the reverse direction. When driven, as indicated by the broken arrow, the brine 13 is returned from the pressure chamber 15 of the cylinder 14 to the brine tank 12 and the piston 16 descends. In this state, the cylinder cap 22 attached to the upper part of the cylinder 14 is opened, and the packed frozen dessert 17 is replaced.
[0005]
[Problems to be solved by the invention]
By the way, as shown in FIG. 5A, the packaged frozen dessert 17 is obtained by storing the frozen dessert 19 in a bag 23 made of a soft resin. Further, an outlet 18a is attached to the upper side of the bag 23 by welding a flange portion 18a provided at the base thereof, and the outlet 18 and the flange portion 18a are made of hard resin. Yes. The flange portion 18a has a different shape depending on how the frozen dessert 19 is packed in the bag 23 and its storage state. For example, the flange portion 18a has a planar shape as shown in FIG. 5 (a) or a shape shown in FIG. 5 (b). As shown, the upper part of the bag 23 has a curved shape.
On the other hand, a convex portion 22a is provided on the back surface of the cylinder cap 22, that is, the surface facing the packaged frozen dessert 17, as shown in FIG. 6A, and the side surface of the convex portion 22a is directed downward. It has a tapered surface that narrows.
[0006]
For this reason, in the planar flange portion 18a as shown in FIG. 5A, the upper end of the flange portion 18a is a taper of the cylinder cap 22 when the cylinder cap 22 is mounted, as shown in FIG. In some cases, the stress is pushed out to the outside along the surface and acts to separate the bag 23 and the flange portion 18a of the packaged frozen dessert 17 from each other. In such a case, the bag 23 made of a soft resin may be damaged due to the pressure applied by the packed frozen dessert 17 during the operation of pouring the frozen dessert 19, and the frozen dessert 19 may leak out.
Further, in the curved flange portion 18a as shown in FIG. 5B, the upper end of the flange portion 18a is a convex portion of the cylinder cap 22 when the cylinder cap 22 is mounted, as shown in FIG. There was a case where it was caught by the tip of 22a and pressed down. In such a case, the cylinder cap 22 is fastened to the upper portion of the cylinder 14 while bending the upper end of the flange portion 18a made of hard resin downward, so that a considerable force is required and the mounting operation of the cylinder cap 22 is difficult.
[0007]
The present invention has been made to solve such problems, and an object of the present invention is to provide a frozen confection supply device capable of easily mounting a cylinder cap on a cylinder while preventing breakage of a bag of packed frozen confectionery. And
