Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention provides a packaging device for manufacturing processed rice food with seaweed and a method for storing the inner bag containing the processed rice food in an outer bag, and more specifically, The inner bag containing processed rice food such as rice balls is inserted into the outer bag through seaweed, and when it is time to eat, open the tip of the outer bag and pull out the inner bag to create the processed rice food with seaweed. The present invention relates to a packaging device that can be used for both manufacturing and manufacturing purposes, and an insertion method for inserting an inner bag containing processed cooked food into an outer bag through seaweed.

(Prior Art) The present applicant has already made an invention as disclosed in Japanese Patent Publication No. 59-41697 as this type of technology.

That is, in this invention, an inner bag capable of storing rice balls is inserted into an outer bag through seaweed, and cutting or dividing means is provided at the tip of the outer bag to make the tip open. When eating, cut or divide the tip of the outer bag to open the tip,
By pulling out the tip of the inner bag protruding from the opening, the rice balls and seaweed are integrated to obtain rice balls with seaweed.

The above-mentioned cutting or dividing means at the tip of the outer bag is provided to prevent moisture from getting into the seaweed and dirt from entering by keeping the outer bag closed until just before eating. It is.

(Problems to be Solved by the Invention) By the way, in the above technique, in order to pull out the inner bag from the outer bag when eating, the tip of the inner bag must be cut off or separated from the tip of the outer bag. Therefore, when inserting the inner bag into the outer bag, the tip of the inner bag should protrude from the opening of the bottomed outer bag, more specifically, from the cut or divided part. It must be inserted all the way to the bottom.

However, in the above-mentioned conventional technology, the inner bag and outer bag, which are packaging materials, are generally made of soft plastic film.
It is a flat bag formed by overlapping two films and thermally welding sealing them at predetermined positions, with the sealed areas serving as the edges on both sides. Opening cannot be done easily and smoothly, and since the tip of the outer bag has a bottom, even if the top surface of the outer bag is opened, the two films remain in contact on the tip side. Therefore, when inserting the inner bag into the outer bag, if you try to forcefully insert it, resistance will occur and the tip of the inner bag will bend, causing the bag to be inserted all the way to the tip of the outer bag. First, there was a serious problem in that after the tip of the outer bag was opened by the cutting or dividing means, the tip of the inner bag did not protrude from the opening.

As a result, it becomes very difficult to pull out the inner bag when eating, and the fact that the tip of the outer bag is bottomed until just before eating makes it even more difficult to insert the inner bag securely. This could have been a negative factor.

The present invention has been made to solve the above-mentioned problems, and when the tip of the outer bag is opened,
The purpose is to insert an inner bag into an outer bag so that the tip of the inner bag reliably projects.

(Means for Solving the Problems) In order to achieve such an object, the present invention solves the above problems by solving the above problems.Although the outer bag is bag-shaped, the sheet is substantially flat before the inner bag is inserted. In view of the problems that have arisen due to the situation, from this perspective, we have developed a packaging device that can be used for manufacturing processed rice food with seaweed, and a packaging device that can be used for manufacturing processed rice food with seaweed, as well as a packaging device that can be used to store processed rice food inside the inner bag. This was done as an insertion method, and its characteristics as a packaging device for both manufacturing and packaging are that the inner bag 7 is inserted into the outer bag 1.
When the outer bag 1 is inserted, at least one pair of folds 6, 6, which form a ridge line together with both side edges of the outer bag 1 and make the outer bag 1 open, are inserted into both facing pieces 1 of the outer bag 1.
a, 1b, respectively, and the feature of the method of inserting the inner bag is that after forming the above-mentioned folds 6 on both pieces 1a, 1b of the outer bag 1,
The purpose is to open the outer bag 1 through the fold line 6 and insert the inner bag 7 containing the processed cooked food into the outer bag 1.

(Function) In other words, since the above-mentioned folds are formed on both facing pieces 1a and 1b of the outer bag 1, when inserting the inner bag 7 containing processed cooked food into the outer bag 1, the outer bag 1 and the fold line 6 form a ridgeline, and the outer bag 1 is opened, the tip 5 is also spread out without any contact between the films, and therefore the inner bag 7 is opened very easily without any resistance. In order to avoid resistance during insertion, the tip of the inner bag is inserted into the outer bag 1 almost to the innermost part of the tip of the outer bag.
Therefore, when the distal end of the outer bag is opened by cutting or dividing, the distal end of the inner bag reliably protrudes from the opening of the distal end.

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

FIGS. 1 and 2 are diagrams respectively showing an outer bag and an inner bag constituting a packaging device for manufacturing rice grips with seaweed as an example.

In Fig. 1, reference numeral 1 denotes an outer bag made of a soft synthetic resin film and having an inverted isosceles triangular shape when viewed from the front.
One piece 1a is extended from the other piece 1b to form a bent piece 3 that can close the opening 2. 4 is a perforation for cutting the tip 5 of the outer bag 1 to form an opening, and is formed in the lateral direction of the tip 5 of the outer bag 1. Reference numerals 6 and 6 are folds that can form a ridge line together with both side edges 1c and 1d of the outer bag 1 when the outer bag 1 is opened, and are formed in the center longitudinal direction of both pieces 1a and 1b of the outer bag 1, respectively.

In FIG. 2, reference numeral 7 denotes a translucent inner bag made of a soft synthetic resin film, and the outer bag 1 is arranged so that a rice ball 8 can be stored therein and inserted into the outer bag 1.
It has slightly smaller external dimensions and is formed in substantially the same shape as the outer bag 1. 9 is the opening 1 of the inner bag 6
0 shows a bent piece formed by extending one piece 7a of the inner bag 7 from the other piece 7b. Reference numerals 11 and 11 indicate folds formed in the center longitudinal direction of both sides 7a and 7b of the inner bag 7, respectively, similar to the folds 6 and 6 of the outer bag 1. Reference numeral 12 denotes a cross-shaped cut which is formed on both sides of the bent piece 9 to allow a large number of the inner bags 7 to be inserted through the hanging rod 13 at the same time so that they can be hung and torn off.

And with the outer bag 1 and inner bag 7 as described above,
The rice ball 8 and seaweed 14 separated in both bags are integrated to constitute a packaging tool that can be used for manufacturing rice balls with seaweed.

Next, an explanation will be given of an insertion method for inserting the inner bag 7 into the outer bag 1 in such a manufacturing/packaging device.

First, a pair of fold lines 6, 6, 11, and 11 as described above are formed in advance on the outer bag 1 and the inner bag 7, respectively. Then, as shown in FIG. 3 of the inner bag 7, a large number of sheets are hung from the suspension rod 11 by inserting the cut 12 into the suspension rod 11.

Next, air is blown into the inner bag 7 to open the opening 10 as shown in FIG.

In this case, the inner bag 7 has both pieces 7a,
Folds 11 and 1 are formed in the longitudinal direction approximately at the center of 7b, respectively.
1 is formed, the crease 1 is formed along with both side edges 7c and 7d of the inner bag 7 when air is blown.
1 and 11 form ridge lines, and the inner bag 7 opens, so that the rice balls 8 can be stored in the inner bag 7 very easily and smoothly.

Thereafter, as shown in FIG. 5, after wrapping seaweed 14 around the outer circumferential surface of the inner bag 7 containing the rice balls 8, as shown in FIG. Insertion of the inner bag into the outer bag is completed by inserting the wrapped inner bag 7 into the outer bag 1. Furthermore, as shown in FIG. 7, by folding the folded piece 3 of the outer bag 1 and pasting the label 15, the seaweed 14 and the rice balls 8 are packaged in a separated state.

In this case, since the folds 6, 6 as described above are formed in the outer bag 1, the folds 6, 6 form a ridge line together with the both side edges 1a, 1b of the outer bag 1, and the outer bag 1 becomes When opened, the distal end 5 also becomes in a spread state where there is no contact between the films, so that the inner bag 7 can be inserted into the outer bag 1 very easily and smoothly, and the insertion can be performed without resistance. The tip 16 of the inner bag 7 is surely inserted almost to the deepest part of the tip 5 of the outer bag 1 as shown in FIG. It will be located at the bottom. Moreover, in this case, the inner bag 7 also has the fold 6 of the outer bag 1.
Similarly, since the fold line 11, which can be ridge-like, is formed, the tip 16 of the inner bag 7 itself is in a spread state where the films do not come into contact with each other, and thus the tip 16 of the inner bag 7 and the outer bag tip Insertion to the side can be performed more reliably.

Therefore, when the seaweed 14 and the rice balls 7 are integrated when eating rice balls with seaweed, when the tip 5 of the outer bag 1 is pinched and cut through the perforations 4 as shown in FIG. Since the tip 16 of the inner bag 7 is located below the perforation 4, the tip 16 of the inner bag 7 can be picked along with the tip 5 of the outer bag 1, and the inner bag 7 can be picked up. 7 can be pulled out from the outer bag 1 very easily.

Furthermore, even when pulling the inner bag 7 after cutting the outer bag 1 without pulling out the inner bag 7 at the same time as cutting the outer bag 1, the tip 16 of the inner bag 7 is inserted to the bottom of the perforation 4. After the outer bag 1 is cut off,
The distal end 16 of the inner bag 7 reliably protrudes from the separated distal opening 17.

Therefore, by pinching the protruding tip 16 of the inner bag 7, the inner bag 7 can be easily pulled out.

In any case, in the above embodiment, since the folds 6, 6 are formed in the longitudinal direction at the approximate center of both pieces 1a, 1b of the outer bag 1, the tip 16 of the inner bag 7
However, immediately after the outer bag 1 is cut and opened, the perforation 4
The inner bag 7 reliably protrudes downward, making it much easier to pull out the inner bag 7 as described above than in the past.

In the above embodiment, both pieces 7a and 7b of the inner bag 7
Since the creases 11 and 11 are formed on the sides, it is easy to insert the rice ball 8 as described above, and
Insertion of the inner bag 7 into the outer bag 1, especially its tip 16
Although the favorable effect of making the insertion into the distal end 5 side of the outer bag 1 easy and reliable was obtained, it is by no means a condition that the inner bag 7 be formed with folds 11, 11 as described above. The point is that such folds only need to be formed at least in the outer bag 1.

In addition, in this embodiment, since the folds 6, 6 are formed in the vertical direction at approximately the center of both pieces 1a, 1b of the outer bag 1, when the inner bag 7 is inserted, the outer bag 1 expands approximately evenly throughout. However, the formation positions of the folds 6, 6 are by no means limited to this, and the point is that when the inner bag 7 is inserted, the outer bag 1 opens and It is only necessary that the folds 6, 6, which can be ridge-like along with 1a, 1b, are formed on both pieces 1a, 1b of the outer bag 1, respectively. Furthermore, the number of folds 6 is not limited to one on each piece as in the above embodiment, but may be formed, for example, two.

Furthermore, it is also possible to point-seal the side surface of the tip 16 of the inner bag 7 as shown in FIG.
In this case, the point seal portion 18 makes the tip 16 of the inner bag 7 very sharp, so that when the inner bag 7 is inserted into the outer bag 1, the tip 16 of the inner bag 7 This has the advantage that the distal end 16 of the inner bag 7 can be inserted almost to the innermost part of the distal end 5 of the outer bag 1 more reliably since the inner bag 7 is less prone to bending or the like.

Furthermore, in the above embodiment, the perforation 4 is formed as a means for cutting the tip 5 of the outer bag 1, but this cutting means is not limited to the perforation 4 as in the embodiment, but also cuts, notches, etc. It is also possible to use other means. Furthermore, in addition to the cutting means that separates the tip portion 5 in this manner, a means that separates the tip portion 5 through perforations, cuts, etc. may be used. In short, it is only necessary that the distal end portion 5 of the outer bag 1 be provided with such means for cutting or dividing.

Furthermore, in the above embodiment, the seaweed 14 is wrapped around the outer circumferential surface of the outer bag 1 and then stored in the inner bag 7, but after the seaweed 14 is installed in the outer bag 1 in advance, the inner bag 7 is removed. It may also be inserted into the bag 1. In short, the outer bag 1 should be inserted into the inner bag 7 so that the seaweed 14 is interposed between the outer bag 1 and the inner bag 7 cans.

Further, the shapes of the outer bag 1 and the inner bag 7 are not limited to the inverted isosceles triangular shape as in the above embodiment, but may also be in an inverted trapezoidal shape or the like.

Incidentally, the type of cooked rice processed food stored in the inner bag 7 is not limited to the rice ball of this embodiment.

(Effects of the Invention) As described above, the present invention is characterized in that at least one pair of folds, which can form a ridge line together with both side edges of the outer bag when the outer bag is opened, are formed on both facing pieces of the outer bag. Therefore, when inserting the inner bag, the outer bag is folded along the fold line and opened, and the tip of the outer bag also spreads out so that the film does not come in contact with the inner bag. It is inserted into the outer bag very easily and smoothly without any resistance, ensuring that the tip of the inner bag reaches the tip of the outer bag, more specifically, below the cut or divided part of the tip of the outer bag. This has the remarkable effect that when the tip of the outer bag is cut or divided and opened, the tip of the inner bag can reliably protrude from the opening. I've reached it.

As a result, the inner bag can be pulled out extremely smoothly and easily at the same time as the outer bag is cut, or after the outer bag is cut or divided.
