Abstract

<P>PROBLEM TO BE SOLVED: To supply dry ice into a thin bag without a handle at a shop front and so on. <P>SOLUTION: The bag 20 is placed on the floor of a supply chamber 11 so as to cover the lower end of an outer cylinder 19. At this time, the upper end of the bag 20 is positioned higher than a side jetting hole 21. When a door 12 is closed and a user pushes a starting switch 18, an electromagnetic stop valve 17 is opened and, then, carbon dioxide gas is jetted from a nozzle 16. On the one hand, carbon dioxide gas is jetted from the side jetting hole 21 and the opening of the bag 20 is held on the position. Thereby, the bag 20 is held in the state of being reliably opened under the outer cylinder 19. Carbon dioxide gas jetted from the nozzle 16, on the other hand, is adiabatically expanded inside a horn 15, becomes dry ice and is supplied from the lower end of the outer cylinder 19 into the bag 20. <P>COPYRIGHT: (C)2003,JPO

That is, by placing the bag-shaped container under the outer cylinder as described above, the opening of the bag-shaped container is held at that position by the carbon dioxide gas ejected from the side ejection holes of the outer cylinder. Therefore, the dry ice falling from the expansion cylinder via the lower end open portion of the outer cylinder is reliably stored inside the bag-shaped container.

The jetting force of the liquefied carbon dioxide gas cylinder, which is the carbon dioxide gas supply source, is not always constant. If the ejection force is too large, the pressure of carbon dioxide gas ejected from the lower opening along with dry ice will become too large, and the retention force at the opening of the bag-shaped container due to the gas ejected from the side ejection holes will be exceeded. May be blown away. Therefore, in such a case, a ventilation hole is provided in the upper side surface portion of the outer cylinder so as to kill the ejection force of carbon dioxide gas ejected into the bag.

A method of using this device will be described with reference to FIGS. 4 (a) and 4 (b). First, the bag 20 is placed on the floor of the supply chamber 11 so as to cover the lower end of the outer cylinder 19. At this time, the upper end of the bag 20 is positioned above the side ejection holes 21 (FIG. 4 (a)). With the bag in that state, the door 12 is closed. When the door 12 is closed, the door switch 14 is actuated and the preparation for gas ejection is completed. Next, the user activates the start switch 1
When 8 is pressed, the solenoid opening / closing valve 17 is opened, and carbon dioxide gas is ejected from the nozzle 16. On the other hand, carbon dioxide gas is emitted from the side ejection holes 2
Squirt out of 1 to hold the opening of bag 20 in place.
As a result, the bag 20 is securely held under the outer cylinder 19 with its mouth open. On the other hand, the carbon dioxide gas ejected from the nozzle 16 adiabatically expands inside the horn 15 to become dry ice, and is supplied into the bag 20 from the lower end of the outer cylinder 19 (FIG. 4B).

In this embodiment, a thin (thickness of 0.01 to 0.03 mm) is put in a supermarket baggage stand or the like to put fresh food or the like.
I used a plastic bag with no handle. The outer diameter of the lower side surface portion of the outer cylinder 19 is set so that it can be easily covered with the opening of the bag to be used. Further, the distance between the lower end of the outer cylinder 19 and the floor of the supply chamber 11 is such that the bottom of the bag is in the supply chamber 11 even if the upper end of the opening of the plastic bag 20 is located above the side ejection holes 21.
Make sure that it does not float above the floor.

The jet output of the liquefied carbon dioxide cylinder is not always constant. If the ejection force is too large, the shape of the opening of the bag 20 placed under the outer cylinder 19 may be broken or blown off, and the dry ice 23 may not be supplied into the bag 20. Therefore, the vent hole 22 is provided in the upper portion of the outer cylinder 19 in order to kill the excessive gas ejection force. As a result, the jetting force of the gas into the bag 20 becomes substantially constant, and the dry ice is surely stored in the bag 20 smoothly and continuously. It should be noted that it is effective to provide the ventilation holes 22 in the shape of slits in the circumferential direction on the upper portion of the outer cylinder 19. Further, it is desirable that the position is below the lower end of the horn 15. According to the above principle, when the bag 20 is placed on the lower end of the outer cylinder 19, the bag 2
It is desirable that the upper end of 0 is located above the side ejection hole 21 and below the vent hole 22.
