Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for producing rice balls with seaweed, and more specifically, a method for producing rice balls with seaweed, and more specifically, a method for separating rice balls and seaweed through a folded synthetic resin film and placing them on each other. After wrapping the rice ball with the film, the folded film is unfolded at the time of eating, and the rice ball is placed on the separated seaweed through the film to produce a rice ball with seaweed. Concerning a method for producing rice balls.

(Prior art) Conventionally, in a method for producing rice balls with seaweed,
As the prior art closest to the present invention,
There is a technology published in Publication No. 35108.

That is, this invention involves folding both ends of a synthetic resin band-shaped film to such an extent that the ends overlap or join together, interposing seaweed inside the folded film, and folding the folded portions on both sides of the film. After sealing and enclosing nori, cut lines are formed inside the roll portions on both sides, rice balls are placed on the overlapping portion of the folded film, and the rice balls are wrapped with the film. It's packaging.

(Problems to be Solved by the Invention) However, in the packaging method disclosed in the above-mentioned invention, there is a step of sealing both sides of the folded film and forming a cutting line inside the sealed portion. Because of this, there was a problem that the number of man-hours for packaging increased as a whole and the work became complicated. In other words, in order to package rice balls by placing them on a belt-shaped film with both ends folded to insert seaweed, the folded film must be wrapped around the rice balls. However, if the film is simply folded so that both edges overlap, there is a risk that the edges of the overlapped film will shift when wrapping the rice ball, and as a result, the sealing process described above becomes necessary. Moreover, as a result of this sealing step being required, a cutting step inside the sealing portion was required in order to unfold the folded sheet during eating.

Furthermore, since the folded film as described above had to be wrapped around the rice ball, the work of wrapping the rice and unfolding the wrapped film when eating became quite complicated. .

In addition, as a solution to the workability of the sealing process, cutting process, and wrapping of rice balls as described above,
For example, there are methods shown in FIGS. 11 to 13. That is, in this method, the plastic film 11 is first conveyed continuously on the conveyor 13a as shown in FIG.
is conveyed and pasted on both ends 10, 10 of the plastic film 11, and after cutting the pasted packaging film as shown in Figure C, it is turned 90° in the direction of arrow A as shown in Figure D. move it to change its position,
This is folded as shown in the figure (E), and then the seaweed 2a is interposed inside the folded film 1a, and then the rice balls 3 are placed on the folded film as shown in the figure (F).
This is a method of wrapping the rice ball 3a with the wrapping film 1a by placing the rice ball 3a thereon, and at the same time twisting both ends 7a of the film as shown in FIG. 12.
Then, when eating, after releasing the twisted state,
As shown in Figure 13, the rice ball 3a can be eaten by pulling out the seaweed 2a, rolling the rice ball 3a in the direction of the arrow B in the figure, placing it on the seaweed 2a, and wrapping the rice ball 3a with the seaweed 2a. This results in a state of

However, in this method, due to the position where the aluminum film is attached, the cut film must be relocated as described above.
However, there was a drawback that the work was complicated.

The present invention has been made to solve all of the above-mentioned problems, and it eliminates the step of sealing both sides of the folded film and the step of cutting the inside of the sealed portion as in the former method. unnecessary,
In addition, there is no need to change the position of the film as in the latter method, which reduces the overall man-hours for manufacturing and simplifies the work.Moreover, it is easy to wrap the rice ball in the film and unfold the film when eating. The purpose of this is to simplify the work itself.

(Means for Solving the Problems) The present invention has been made to solve the above-mentioned problems in order to achieve the above-mentioned object. The premise is a method for producing a rice ball with seaweed, in which the rice ball is placed on the overlapped portion of the folded film and packaged, and then the seaweed and the rice ball are integrated.
Based on this premise, the entire packaging film 1 is made of a non-restorable film in which both ends 7, 7 do not restore after twist wrapping, and aluminum is vapor-deposited on the packaging film 1, and the rice grips 3 using the packaging film 1 are The packaging is carried out only by twisting both ends of the packaging film 1 made of the non-recoverable film, and the packaging film 1 is folded at its folded portion 15,
This is characterized in that it is carried out by not sealing 15.

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

First, a non-recoverable film made of synthetic resin that is continuously conveyed on the conveyor 13, that is, immediately after wrapping with both ends twisted, is a non-recoverable film that does not immediately return to its original state even if the hands are removed. Aluminum is vapor-deposited on one half of the plastic film, and as shown in FIG. 1, it is cut to be slightly longer than the seaweed 2 and the rice balls 3 to form the packaging film 1. Next, a second
As shown in the figure, the seaweed 2 is placed on it, and then, as shown in FIG.
Both side edges 4, 4 are folded inward through folding parts 15, 15 so that they slightly overlap to form both sides 8, 8, and the seaweed 2 is interposed in the folded packaging film 1. Next, a fourth
As shown in the figure, heat sealing 6 is applied, and then as shown in FIG. Both ends 7, 7 of the packaging film 1 are twisted to complete the twist wrapping of rice shakes as shown in FIG.

Incidentally, since the packaging film 1 formed after the above-mentioned cutting process is made of a non-recoverable film, it is configured such that the entire surface of the film can be maintained in a twisted state without being restored. Therefore, in the above-mentioned cut state, both ends 7, 7 of the packaging film 1 are already configured to be able to maintain the above-mentioned twisted state, and the packaging film 1 can be folded in that state. Therefore, without changing the position of the packaging film 1, it is possible to proceed directly to the process of placing the seaweed and folding the film.

Next, in the case of twist-wrapping the rice shakes wrapped in this way, when eating the wrapped rice shakes, first, from the twist-wrapping state as shown in FIG. Release the condition. Next, while unfolding and spreading the packaging film 1 on both sides of the rice ball 3 as shown in FIG.
At the same time, the overlapping state of the side edges 4, 4 is released, and the folded packaging film 1 is opened outward as shown in FIG.

At this time, since both sides 8, 8 of the film 1 are pulled outward at the same time, the rice ball 3 hardly rolls and falls onto the seaweed 2 under its own weight as shown in FIG. 8 and is placed thereon. Then, when the unfolded packaging film 1 is wrapped inside as it is, the seaweed 2 is naturally wrapped around the rice ball 3 and can be eaten as a seaweed roll.

In the above embodiment, the overlapping part 5 is formed by folding the packaging film 1 so that the longitudinal side edges 4, 4 of the packaging film 1 overlap slightly as shown in FIG. The manner in which the overlapping portion is formed is not limited to the embodiment described above; for example, as shown in FIG. As shown in FIG. 9B, tape-like tension pieces 9, 9 may be attached outward to both side edges 4, 4 of the packaging film 1 folded inward. The point is that when both sides 8, 8 of the film 1 are pulled outward at the same time, the rice ball 3 is attached to the film 1.
It is sufficient if the structure is such that it falls from the overlapping part of the seaweed 2 and is placed on the seaweed 2. However, if it is formed as shown in FIG. 9 A and B above, the both side edges 4, 4 or the tension pieces 9, 9 of the film 1 can be pulled very easily, and the rice balls 3 can be placed on the seaweed 2 even more easily. I can do it.

Further, in the above embodiment, a seal 6 is provided at one location approximately in the center of the overlapping portion 5 to prevent the overlapped side edges 4, 4 of the inwardly folded packaging film 1 from shifting.
However, this seal 6 is not limited to one in which only the overlapping portion 5 of the packaging film 1 is sealed as in the embodiment, but may be one in which the seaweed 2 is sealed together with the film 1. In this case, there is an effect that the seaweed 2 is fixed and does not shift on the non-restorable film 1.

Furthermore, the seal 6 may be applied to the overlapping portion 5 of the both side edges 4, 4 of the packaging film 1 as required, and is not necessarily essential to the present invention.

Further, in the above embodiments, polypropylene film is used as the material for the non-restorable film, but other materials such as polyethylene film and cellophane may also be used.

Furthermore, aluminum does not necessarily need to be deposited on half of the plastic film as in the above embodiments, but may be deposited on the entire surface or a portion of the film. In short, it is sufficient that the entire surface of the film is made of a non-recoverable film that can maintain the twisted state.

Furthermore, in addition to the above embodiments, when aluminum is vapor-deposited on a film through a protective film and then the aluminum is melted, the deposited aluminum remains only in the areas where the protective film is present. By applying it to a desired position on the film, various patterns such as those shown in FIG. 10 can be created on the film.

In addition, the above-mentioned method for producing rice balls with seaweed includes sushi rolls,
It can be applied to all kinds of processed rice with seaweed, such as rice balls.

(Effects of the Invention) (a) As mentioned above, the present invention does not require wrapping a belt-shaped film around a rice ball as in the conventional method described above, but twists both ends of the non-recoverable film as described above. This makes it possible to produce rice balls with seaweed by wrapping the rice balls in the same way and untwisting them when eating, so when wrapping the rice balls and eating them, the film is unfolded and the rice balls are placed on top of the seaweed. A remarkable effect has been achieved in that the work of placing and winding can be performed much more simply and quickly than in the past.

(b) Furthermore, since the packaging film is entirely composed of a non-recoverable film, there is no need to change the position of the film, unlike in the above-mentioned conventional manufacturing method using an aluminum vapor-deposited film.

(c) An even more important point is that the seaweed and rice balls can be integrated by simply twisting and unwrapping both ends of the folded film as described above.
Moreover, since the film itself is a non-recoverable film and the folded portion can be formed reliably, both ends of the stacked films can be shifted during twist wrapping and unwrapping, even without applying a conventional seal to the folded portion. This eliminates the need for the sealing process at the film folding part and the cutting process inside the sealing part, which were previously essential, reducing the overall manufacturing man-hours.
This has the special effect of simplifying the overall work.

(d) Furthermore, since aluminum is vapor-deposited on the non-recoverable film, the entire packaging film becomes glossy, and as a result, the characters etc. displayed on the packaging film can appear even more clearly, and the colors and
There is an advantage that a non-recoverable film with an extremely excellent design can be formed by applying patterns or the like in various ways.
