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 that stores processed rice foods such as rice balls,
A packaging device that can be used for manufacturing a processed rice food with seaweed by inserting it into an outer bag through seaweed, packaging it, and opening the tip of the outer bag and pulling out the inner bag when eating, and a processed rice food with seaweed. This relates to an insertion method for inserting an inner bag containing a seaweed into an outer bag through seaweed.

(Prior art) The applicant has already developed this type of technology in Japanese Patent Publication No. 59
The invention is published in Publication No.-41697.

That is, in this invention, an inner bag capable of storing rice balls is inserted into an outer bag through seaweed, and a cutting or dividing means is provided at the tip of the outer bag to make the tip open. At the time of eating, the tip of the outer bag is cut or divided to open the tip, and the tip of the inner bag protruding from the opening is pulled out to integrate the rice balls and seaweed to make rice balls with seaweed. It is something that you are trying to gain.

The above-mentioned cutting or dividing means at the tip of the outer bag is provided to prevent moisture from 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 or separated before 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, and more specifically, the tip of the inner bag should be on the side of the bottom of the bottomed outer bag, more specifically, below the cut or divided part. It must be inserted all the way to the side.

However, in the above-mentioned conventional technology, the inner bag and outer bag used as packaging materials are generally made of soft plastic films, and more specifically, they are made by overlapping two films and thermally sealing them at predetermined positions. Since it is a flat bag with the sealed portion as the edges on both sides, the two sides of the facing bag come into contact, making it difficult to open the bag easily and smoothly. Since the film has a bottom, even if the top surface of the outer bag is open, the two films may remain in contact with each other on the tip side. Therefore, when inserting the inner bag into the outer bag, it may be difficult to If you try to insert it into the outer bag, resistance will be generated and the tip of the inner bag will be bent so that it will not be inserted all the way to the tip of the outer bag. Therefore, after the tip of the outer bag is opened by the cutting or dividing means, However, there was a serious problem in that the tip of the inner bag did not protrude from the opening at the tip.

Therefore, 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, which is a rather negative point. This could also be a factor.

The present invention has been made in order to solve the above-mentioned problems, and it is necessary to insert the inner bag into the outer bag so that the front end of the inner bag reliably protrudes when the front end of the outer bag is opened. The purpose is to tighten.

(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 above-mentioned situation, from this point of view, 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 the 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.
At least one pair of folds 6. form a ridge line together with both side edges of the extranuclear pouch 1 and open the extranuclear pouch 1 when the extranuclear pouch 1 is inserted.
6, both facing pieces 1a of the outer nuclear bag 1;

1b, respectively, and the feature of the method for inserting the inner bag is that after forming the above-mentioned folds 6 in advance on both pieces 1a and 1b of the outer bag 1, the outer bag is inserted through the folds 6. Open the bag 1 to see the inner bag 7 in which processed cooked food is stored.
is inserted into the outer bag 1.

(Function) In other words, since the above-mentioned folds are formed on both facing pieces 1a and lb 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, the outer bag 1 opens, and the tip 5 also spreads out so that there is no contact between the films, so that the inner bag 7 can be opened very easily without any resistance. In order to be inserted into the outer bag 1 and not receive any resistance during insertion, the tip of the inner bag must be inserted almost to the innermost part of the outer bag on the tip side. When the tip is opened by cutting or dividing, the tip of the inner bag reliably protrudes from the opening of the tip.

(Example) Embodiments 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. An opening 2 is formed on the top surface, and one piece 1a of the outer bag 1 passes through the opening 2 to the other piece 1b. A bent piece 3 that can be extended to close the opening 2 is formed. Reference numeral 4 denotes a perforation for cutting the distal end 5 of the outer pouch 1 to form an opening, and is formed in the lateral direction of the distal end 5 of the outer nuclear pouch 1. 6.6 is a fold that can form a ridge line together with both side edges 1c and ld of the outer pouch 1 when the outer pouch 1 is opened, and is formed in the longitudinal direction at the center of both pieces 1a and lb of the outer pouch 1.

In FIG. 2, reference numeral 7 denotes a translucent inner bag made of a soft synthetic resin film, in which a rice ball 8 can be stored, and the outer bag 1
The external size is slightly smaller than the outer nuclear bag 1 and is formed in substantially the same shape as the outer nuclear bag 1 so that it can be inserted into the nuclear outer bag 1. 9 inserts one piece 7a of the inner bag 7 from the opening 1° of the inner bag 6 into the other piece 7.
A bent piece formed to extend from b is shown. Ratio 11 is similar to the fold line 6.6 of the outer bag 1, and both pieces 7a of the inner bag 7.
, 7b, each showing a fold formed in the central longitudinal direction. 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.

The outer bag 1 and the inner bag 7 as described above constitute a packaging device that can be used for manufacturing rice balls with seaweed by integrating the rice balls 8 and seaweed 14 separated in both bags.

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 tool.

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. A large number of inner bags 7 are suspended from the suspension rod 11 by passing through the cut 12 into the suspension rod 11 as shown in FIG.

Next, as shown in FIG. 4, air is blown into the inner bag 7 to open the opening 10, the rice ball 8 is stored in the inner bag 7, and the inner bag 7 is torn off from the hanging rod 11.

In this case, since the inner bag 7 has creases 11 and 11 formed in the longitudinal direction approximately at the center of both pieces 7a and 7b, both edges 7c and 7c of the inner bag 7 are formed when air is blown into the inner bag 7.
Together with 7d, the folds 11.11 become ridge-like, and the inner bag 7 opens, making it possible to store the rice ball 8 into 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 in which the rice balls 8 are stored, the outer bag 1 is wrapped as shown in FIG.
The insertion of the inner bag into the outer bag is completed by inserting the inner bag 7 wrapped with seaweed 14 into the outer bag 1 while opening the opening 2 of the bag. 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, the outer bag 1 has the above-mentioned folds 6,
6 is formed, the fold line 6°6 becomes a ridge line along with both side edges 1a and lb of the outer bag 1, and the outer nuclear bag 1 opens, and its tip 5 also becomes a spread state where there is no contact between the films. Therefore, the inner bag 7 is inserted into the outer bag 1 very easily and smoothly, and since the insertion is performed without resistance, the tip 16 of the inner bag 7 is inserted into the outer bag 1.
As shown in Figure (B), the tip 5 of the outer bag 1 is inserted securely to the innermost part, and the tip 16 of the inner bag 7 is inserted into the perforation 4 of the outer bag 1.
It will be located below. However, in this case, the inner bag 7 is also formed with a crease 11 that can be ridge-like like the fold i of the outer bag 1, so that the tip 1 of the inner bag 7
6 itself is also in a spread state with no contact between the films,
Therefore, the tip 16 of the inner bag 7 can be inserted into the tip of the outer bag more reliably.

Therefore, when the seaweed 14 and the rice ball 7 are integrated when eating the rice ball with seaweed, when the tip 5 of the outer bag 1 is pinched and cut through the perforation 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. It can be pulled out from the outer bag 1 very easily.

Furthermore, even when pulling out 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 inner bag 7
Since the distal end 16 of the outer bag 1 is inserted to the bottom of the perforation 4, after the outer bag 1 is separated, the distal end opening 1
The tip 16 of the inner bag 7 will surely protrude from the inner bag 7.

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

In any case, in the above embodiment, both pieces la of the outer bag 1,
Since the folds 6 and 6 are formed in the longitudinal direction at approximately the center of lb, the tip 16 of the inner bag 7 reliably protrudes below the perforation 4 immediately after the outer bag 1 is cut and opened. The inner bag 7 can now be pulled out much more easily than before.

In the above embodiment, the creases 11 and 11 are formed on both pieces 7a and 7b of the inner bag 7, so that the rice balls 8 can be easily inserted as described above, and the inner bag 7 can be easily inserted into the outer bag 1. Although the favorable effect of making the insertion, especially the insertion of the distal end 16 into the distal end 5 side of the outer bag 1, easy and reliable was achieved, forming the folds 11 and 11 as described above in the inner bag 7 was advantageous. This is by no means a condition; 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 substantially the center of both pieces 1a and lb of the outer bag 1, when the inner bag 7 is inserted, the outer bag 1 expands almost evenly throughout. However, the formation position of the fold line 6.6 is by no means limited to this, and the point is that when the inner bag 7 is inserted, the outer bag l opens and the fold line 6.6 is formed on both sides of the outer bag l. 1a,
The folds 6, 6, which can become ridge-like along with lb, are the outer bag 1.
It suffices if they are formed on both pieces 1a and 1b, respectively. Further, the number of folds 6 is not limited to one for each month 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. 9; in this case,
The tip 16 of the inner bag 7 is sealed by the point seal portion 18.
has a very sharp shape, so when the inner bag 7 is inserted into the outer bag 1, the tip 16 of the inner bag 7 is less likely to break. It has the advantage that it can be inserted even more reliably to the innermost part of the portion 5.

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 l 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 It may also be inserted into the bag. 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 embodiments, 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) Similar to soft soil, the present invention has at least one pair of creases that can form a ridgeline along with both side edges of the outer bag when the outer bag is opened, respectively, formed on both facing pieces of the outer bag. Therefore, when the inner bag is inserted, the outer bag is folded along the above-mentioned fold line and opened, and the tip of the outer bag also spreads out so that the film does not come into contact with it, so that the inner bag containing the cooked rice processed food does not come into contact with the film. It is inserted into the outer pouch very easily and smoothly without any resistance, and the tip of the inner pouch is securely inserted to the distal end side of the outer pouch, more specifically, to the bottom of the cut or divided portion of the distal end of the outer pouch. It will be inserted,
Therefore, when the tip of the outer bag is cut or divided to open it,
A remarkable effect has been achieved in that the distal end of the inner bag can reliably protrude from the distal opening.

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 into two pieces.
