(Example) Embodiments of the present invention will be described below with reference to the drawings.

(First example) 1 to 4 show a first embodiment.

In the figure, l is a solidification molding device for a product 2 such as a popsicle, for example. This apparatus 1 has a storage bag 4 for containing a fluid material to be formed 3, which is a raw material for the product 2.

The storage bag 4 has transparent resin sheets 6 facing each other.
6, and is formed by welding the left and right side edges and the underlined portions of these sheets 6.6 to each other by heating (hereinafter simply referred to as welding). The upper part of the storage bag 4 is opened toward the outside, and this opening serves as an injection lower for injecting the material to be formed 3 into the storage bag 4.

Further, a fastener 8 is formed on the injection lower to open and close the injection lower.

The fastener 8 includes a protrusion 9 formed on the inner surface of one sheet 6 facing each other in the injection lower, and a groove formed on the inner surface of the other sheet 6 into which the protrusion 9 is removably fitted. It is composed of IO. In addition to the above, the fastener 8 may be any other means as long as it can seal the injection lower.

A discharge port 12 is formed in the lower part of the storage bag 4 between the lower edges of both sheets 6.6. This discharge port 12 is for discharging the molded material 3 inside the storage bag 4.

On the other hand, 13 is a molded bag for the product. Molded bag for this product 1
Like the storage bag 4, the storage bag 3 also includes transparent resin sheets 14.14 facing each other, and is formed by welding the outer edges of these sheets 14.14 together. In addition, at the midway point in the left-right direction of the molded bag 13 for a product, both sheets 14 and 14 cover the inside of the molded bag 13 for a product 5 times.
They are welded together to divide them into equal parts.

Therefore, this product molded bag 1 is formed by an outer edge welded part 15 where the outer edges of the sheets 14 and 14 are welded to each other, and each partition welded part 16 which partitions the inside of the product molded bag 13 as described above.
Five compartments 18 are formed within the compartment 3, and each of these compartments 18 is vertically long and has the same shape.

Furthermore, a communication path 19 is formed in the product molded bag 13 to allow the compartments 18 to communicate with each other. That is, the lower end of each partition welded part 16 is a little apart from the lower edge welded part 15a of the outer edge welded part 15, and these partitioned welded parts 16
The communication path 19 is between the lower end of the lower edge welded portion 15a and the lower edge welded portion 15a.

In addition, there are two seams (14.
A pressurization port 21 is formed between the upper edges of the pressurization port 14.
is located at the upper part of the compartment 18 in the center of the left and right sides. This press inlet 21 is for press-fitting the molded material 3 into the product molding bag 13.

A flat connecting cylinder 22 is provided that communicates the outlet 12 of the storage bag 4 with the press inlet 21 of the product molding bag 13. That is, this connecting cylinder 22 is formed by making vertically long transparent resin sheets 23 and 23 face each other and welding their left and right edges to each other, and the upper end of this connecting cylinder 22 is connected to the discharge port. 12 and welded to the inner peripheral surface of this discharge port 12. On the other hand, the lower side of the connecting cylinder 22 is inserted into the press port 21 and welded to the inner circumferential surface of the press port 21.

In the above case, the lower end of the connecting cylinder 22 extends into the compartment 18, and the lower end of the connecting cylinder 22 allows the material to be formed 3 to flow only from the storage bag 4 side to the product forming bag 13 side. This is a check valve 25 that does this. In other words, when the material 3 to be formed is about to flow back from the product forming bag 13 side to the storage bag 4 side, the lower end of this connecting cylinder 22 receives external pressure on its outer surface, as shown by the imaginary line in FIG. Therefore, this connecting cylinder 22
The two sheets 23 and 23 forming the cylindrical body 23 and 23 are in close contact with each other and close the inside of the connecting cylinder 22, thereby preventing the above-mentioned backflow.

Next, the product 2 is placed in the solidification bag W11 of the product with the above configuration.
The method for molding will be explained.

First, in order to remove the air inside the molded product bag 13', the two sheets 14 and 14 that make up the molded bag 13' are brought into close contact with each other, and then,
A desired amount of the material to be formed 3 is injected into the storage bag 4 through the injection lower. At this time, if necessary, the material to be formed 3 is stirred and mixed in the storage bag 4. Next, the injection lower is closed with the fastener 8, and from this state, the storage bag 4 is moved as shown by the imaginary line in FIG.
is sequentially compressed from the injection lower side toward the discharge port 12 side.

Then, the material to be formed 3 in the storage bag 4 is pressurized, and the material to be formed 3 flows in the direction of the solid line arrow in the figure.
is first press-fitted into the left-right center compartment chamber 18 through the press inlet 21. When the compression of the storage bag 4 is continued, the material to be formed 3 is further press-fitted into the compartment 18, and the material 3 to be molded passes through the communication path 19 and is filled into the other compartments 18 as well.

In the above case, each compartment 18 is deformed so that its cross section is approximately circular. In addition, the state of discharge of the material to be formed 3 from the storage bag 4 and the state of filling of the material to be formed 3 into the one compartment chamber 18 are as follows:
Since the storage bag 4 and the product molded bag 13 are transparent, they can be visually recognized from the outside.

When each compartment 18 is filled with the material 3 to be formed, the compression of the storage bag 4 is released, thereby completing the press-fitting of the material 3 into the product forming bag 13. In this case, the internal pressure of the product molding bag 13 becomes higher than the internal pressure of the storage bag 4, and the molded material 3 tends to flow backward from the product molding bag 13 side toward the storage bag 4 side. . However, at this time, the check valve 25 is closed and the storage bag 4 and the product molded bag 13 are isolated, so that the above-mentioned backflow is prevented.

If the material to be molded 3 is a raw material for popsicles, for example, the material to be molded 3 in the product molding bag 13 is frozen and solidified together with the product molding bag 13 in a refrigerator or the like. In this case, the storage bag 4 is removed from the product molded bag 13.
The connecting cylinder 22 may be cut between the two 4.13 in order to separate them.

When the solidification of the material to be formed 3 is completed, the corners of the product molding bag 13 are cut off as shown by the imaginary cutting line 26 in FIG. Peel off the two constituent sheets 14.14, and
When the product 2 is taken out from within the product molding bag 13, products 2 having the same shape that match each compartment 18 are obtained.

When taking out product 2 as above, one sheet 14.1
4 are welded together, so this sheet 14
．． The work of peeling off the 14-meter strip can be done relatively easily. In other words, the product 2 can be easily taken out.

Although one or more of them is according to the illustrated example, the connecting cylinder 22 may be detachably fitted into the press inlet 21. In this case, the storage bag 4 is not connected to the molded bag 13 for other products. It can be used any number of times. Further, the check valve 25 may be formed at the discharge port 12 or the pressure inlet 21.
9 may be formed either above or below the partition welded portion 16.

(Second example) 5 and 6 show a second embodiment.

In the figure, the storage bag 4 has an inverted triangular shape, and a connecting cylinder 22 in the shape of an inverted truncated cone is attached to the bottom thereof. This connecting cylinder 22 is made of resin and has rigidity. On the other hand, the inside of the product molded bag 13 is partitioned into four compartments 18 by three partition welds 16, and communication passages 19 are formed at the lower ends of the partition welds 16 at the right and left ends, respectively. A communication passage 19 is formed at the upper end of the central partition welded part 16.

Further, the pressure inlet 21 is formed in the upper part of the compartment chamber 18 at the right end, and when the lower end of the connecting cylinder 22 is removably fitted into the presser inlet 21, the outer circumferential surface of the connecting cylinder 22 is
It is designed to come into pressure contact with the inner circumferential surface of 1.

Therefore, when the material to be formed 3 is press-fitted into the product forming bag 13, the material to be formed 3 flows sequentially from the rightmost compartment 18 to the leftmost compartment 18 inside the product molding bag 13. is filled with.

The other configurations are the same as those of the first embodiment.

In addition, examples of products 2 that can be molded using the above method and apparatus include the following.

That is, in addition to the above-mentioned popsicles, items to be frozen after being filled into the molded product bag 13 include frozen tofu, chocolate, and preserved blood samples. However, in this case, the product molded bag 13 needs to be molded from a cold-resistant material.

Further, after filling the molded product bag 1-3, there are things that can be heated in a microwave oven, such as tamagoyaki, kutsuki, bread, etc., and things that can be boiled, such as konnyaku and stick dumplings. However, in this case, the product molded bag 13 needs to be molded from a heat-resistant sheet 14, 14.

Furthermore, examples of materials that can be naturally dried include concrete blocks.

(Effect of the invention) This invention has the following effects.

That is, the product can be molded by simple manual operations such as injecting the material to be molded into the storage bag and compressing the storage bag, and therefore, the product can be easily obtained by simple operations.

Moreover, the device for molding the product is mainly composed of two bags, a storage bag and a product molding bag, and since such a bag has a simple structure, it can be easily molded.

In the above case, it is preferable that the storage bag can be used any number of times for molding bags for other products, since the device can be used effectively.

In the above case, a check valve may be provided that allows the material to be formed to flow only from the storage bag side to the product molding bag side, and at least one of the storage bag and the product molding bag side may be provided. It may be formed from a transparent sheet, or the molded bag for the product may be formed by welding two resin sheets facing each other, and when constructed in this way,
The work of molding the product becomes easier.
