Description

[Detailed Description of the Invention] <Industrial Application Field> The disclosed technology belongs to the technical field of soft resin packaging materials used for mass production of simple rice balls.

Accordingly, the present invention consists of an outer bag and an inner bag, each having a triangular shape or the like, made of a soft resin sheet such as soft vinyl, with seaweed interposed between the two, and rice balls placed inside the inner bag. After the rice is filled and the inner bag is pulled out from the bottom, seaweed is wrapped directly around the rice ball, and a tear-off part for pulling out the inner bag is pre-formed at the tip of the outer bag. This invention relates to a rice ball packaging material, in particular, the above-mentioned seaweed is interposed in advance between the outer bag and the inner bag, and three layers of these are stacked on top of each other before filling with rice ball rice. The entire circumference of the inner bag is sealed, and at least the filling/unsealing part of the entire circumference is welded and sealed, and the filling/unsealing part is once folded after the rice balls are filled into the inner bag. This invention relates to a rice ball packaging material that is secured to an outer bag with a point seal or the like, and further has an inner bag and an outer bag that are overlapped and welded and sealed at the filling/opening section.

<Prior art> As is well known, the so-called restaurant industry has become extremely prosperous due to the recent diversification and complexity of people's lives, and bread, sandwiches, rice balls, etc. are becoming increasingly popular among working people. Among them, it has become popular not only as a substitute for breakfast at station stands, but also for lunch, and a large amount is being consumed in parking areas of expressway corridors.

Among these, onigiri rice balls are in extremely strong demand due to the so-called traditional aspect of Japanese food, and the supply side is also preparing a system to quickly respond to this demand through the distribution market.

・Thus, in the balance between the restaurant industry and the distribution market,
Hygiene issues are unavoidable, and in particular, there are various problems in maintaining a simple and quick large-scale ready supply due to seasonal factors such as summer, and in addition to these, there are cost issues. The current situation is that there are major bottlenecks.

In other words, there are time and regional constraints from production to consumption, and there are also strict requirements for high quality and sanitary conditions, and on the supply side, there is a dual problem: the supply side must be cost-effective. There are three difficult conditions.

To solve these problems, there are primarily technical solutions, and various inventions have been devised in related industries, some of which are on the way to practical use.

Among these, in order to meet the needs of consumers for simplicity and speed, for example, rice balls are filled inside an inner bag made of a soft resin sheet such as soft vinyl, and the inner bag is filled with rice balls on the outside. By inserting seaweed through a bag and wrapping it with a heavy outer bag made of the same material, a sanitary condition is maintained by sealing off external moisture and germs from the rice and seaweed. When actually eating rice balls, the inner bag was removed and nori was wrapped directly around the rice balls, and by opening the filling and unsealing part of the outer bag, onigiri rice balls were developed and used as needed. It is becoming more and more common.

Recently, a rapidly increasing number of inventions and devising techniques that have made this phenomenon possible have been applied for and announced.
- Although the invention of No. 169067 is excellent in theory and principle, and if it is put into practical use, it is expected to be effective to a certain extent, it is difficult to remove seaweed from the rice balls inside the inner bag. The winding is actually erased in terms of points such as s! Over time, people with little experience in consumption have not been able to check the quality of their products, and as a result, various complaints have been made.

<Problems to be solved by the invention> However, the biggest problem in terms of actual consumption by consumers is that the filling opening part for pulling out the inner bag from the outer bag during actual consumption is Although they are pre-formed, the so-called open type does not completely solve the sanitary problem of easy entry of moisture and germs, and also requires complicated processes such as manufacturing, storage, transportation, and display. When passing through the distribution market, seaweed absorbs moisture and deteriorates, leading to problems such as a decrease in taste or lack of flavor when eaten, and the problem of difficulty in opening smoothly at the filling and opening section. There was also.

In addition, creating a completely sealed type simply increases the number of man-hours on the manufacturing side, which has the disadvantage of increasing costs.
For consumers, there is a negative point in that they cannot handle it as they wish, and for example, there is also a disadvantage in that they cannot be easily handled freehand with one hand when driving a car.

The purpose of the invention of this application is to solve the problems that hinder the mass consumption of rice balls, especially their packaging materials, based on the above-mentioned prior art, and to make it possible to produce them manually at low cost.
Despite the complex distribution process from production to consumption, it is hygienic! To provide an excellent rice ball packaging material that fully satisfies all necessary conditions such that the elasticity is sufficiently maintained and that it can be used extremely easily by consumers during consumption, thereby benefiting the field of food service use in the distribution industry. This is what I am trying to do.

In order to solve the above-mentioned problems, the structure of the invention of this application, which is based on the above-mentioned claims, is to solve the above-mentioned problems. The entire circumference of the outer bag and inner bag of the rice ball packaging material is made into a triple layered structure by folding seaweed in a predetermined manner between the outer bag and inner bag made of a soft resin such as molded soft vinyl. In particular, at least the filling and unsealing part is sealed by welding and sealing, and the packaging material is in a state where onigiri rice can be filled. Open the package and fill it with onigiri rice.
Therefore, in the process leading up to this, the seaweed inserted between the inner bag and outer bag is protected against moisture and mold from the outside.
It maintains a completely sealed sanitary condition, and even if the rice balls are filled manually or the packaging material is handled, the seaweed can maintain its sanitary condition completely, and After the rice balls are filled into the inner bag through the filling/unsealing part, the filling/unsealing part is folded and attached to the outer bag with a point seal etc. with the inner and outer bags sealed all around. Alternatively, the filled and unsealed parts of the packaging material are overlapped and welded-sealed so that the onigiri remains completely sealed and stored, transported, and displayed until consumption, so that it is not consumed by the consumer. When eating, remove the point seal or cut off the welded seal for the filling and opening part, remove it, and pull strongly on the cut-off part at the lower end of the outer bag to separate the cut-off part of the outer bag and remove the inner bag. Accordingly, the seaweed is immediately wrapped around the rice ball inside the outer bag, allowing the consumer to properly eat the fully formed rice ball from the opened filling part. The measures taken were as follows.

<Example-Structure> What is shown in FIG. 1 is a rice ball packaging material 1 that constitutes the gist of the invention of this application, and its inner bag 2 and outer bag 3 are
As shown in the figure, it is a roughly triangular bag-shaped bag (therefore, it is folded into two sheets), and is made of a soft resin sheet such as soft vinyl, with each side facing away from the other. The filling/unsealing part 4.5 is formed in an open state, and there is a thin wall part similar to a so-called integral hinge slightly inside the opening part, which has sufficient sealing properties and is easy to cut out. A cut-off part 6 is formed in advance, and welded seals 7.8 are formed on the other two sides, forming each inner bag 2 and outer bag 3 into a triangular bag as shown in Fig. 2.3. are doing.

Although it is not formed on the inner bag 2, as shown in FIG. 3, a cut-off part 9 is formed in advance in the tip of the outer bag 3 in parallel to the cut-off part 6, similar to the above-mentioned cut-off part 6. .

Therefore, in both the inner bag 2 and the outer bag 3, the cut-off part 6.6 is cut off by applying force and pulling, and in the outer bag 3, the cut-off part 9 at the tip thereof is similarly cut off. It is designed to be separated by pulling.

Also, what is shown in FIG. 4 is seaweed 10, which is a rectangular material that is folded as shown in the figure to form a funnel shape or a substantially triangular truncated pyramid shape.

Therefore, rice ball packaging material 1 is made using these three types of materials.
To do this, as shown in FIG. 4, the seaweed 10 folded into a funnel shape is attached to the outside of the inner bag 2 shown in FIG. 2, and the outer bag shown in FIG. 3 is attached to the outside of the seaweed 10. 3 through the filling/unsealing part 5 of the inner bag 2 and the filling/unsealing part 5 of the outer bag 3 as shown in FIG. A welding seal 11 is formed through the welding seal 11.

Therefore, in the state shown in FIG. 1, although the filling and opening portion 4 of the inner bag 2 is welded and sealed on the front and back with the filling and opening portion 5 of the outer bag 3 by the welding seal 11, the inner bag 2 is integrally sealed. The filling/unsealing part 4 of the bag 2 is kept open inside and outside.

That is, although the inner bag 2 and the outer bag 3 are sealed with the folded funnel-shaped seaweed 10 shown in FIG. The filling/unsealing part 4 of the inner bag 2 is in an open state.

Therefore, the inner bag 2 and the outer bag 3 are placed in the filling/opening part 4 between them.
．． It is made into a packaging material as a triple-layered bag in which seaweed 5 is sealed and folded seaweed 10 is inserted.

Therefore, once the above-mentioned triple bag rice ball packaging material is formed, the space between the inner bag 2 and the outer bag 3 is sealed with the seaweed 10 interposed, so that it is blocked from the outside air. Therefore, the seaweed 10 is completely sealed from moisture, mold, etc.

Thus, onigiri packaging material 1 as shown in FIG.
When it is formed as a raw material and used to make onigiri,
The rice balls are manufactured manually or automatically using a suitable manufacturing device.

Therefore, the manufacturing process will be explained using the flow sheet shown in Fig. 7 and below. As shown in Fig. 7.8.9, as mentioned above,
The seaweed 10 is folded in a predetermined manner as shown in FIGS. 9 and 10, and layered in a triple bag with the inner bag 2 shown in FIG. 7 on the inside and the outer bag 3 shown in FIG. 8 on the outside, A triangular triple bag as shown in FIG. 11 is formed, and as described above, the above-mentioned heat seal is placed slightly above the separation part 6.6 with respect to the filling and opening part 4.5 of the inner bag 2 and outer bag 3. Alternatively, the welded seal 11 is formed by means such as ultrasonic welding.

Of course, the inner bag 2 and the filling/unsealing part 4 are in an open state in this step.

Then, as shown in FIG. 12, the filling/unsealing part 4 of the inner bag 2 of the packaging material 1 is opened and a predetermined amount of rice balls 12 is filled manually or by an automatic filling device as described above.

Therefore, even in this case, since the space between the inner bag 2 and the outer bag 3 is sealed by the welding seal 11, the seaweed 10 does not absorb the warm air of the rice balls, etc., and does not dry out. Maintained.

After filling the onigiri rice 12, heat sealing,
Alternatively, as described above, the welding seal 1 may be applied to the filling and opening portions 4.5 of the inner bag 2 and outer bag 3 by supersonic welding or the like, again overlapping the welding seal 11 previously applied at the time of manufacturing the packaging material 1.
By performing step 3, the filling and opening section 4 of the inner bag 2 and outer bag 3 is completed.
5 is completely stacked in four layers and welded and sealed to form packaging material 1.
The filling and unsealing portion of the container is completely hermetically sealed.

Therefore, the rice balls in this state are made into rice balls 14 shown in FIG. 6, and are displayed in a predetermined manner at supermarkets, parking area shops, etc., and delivered to consumers.

Therefore, the consumer who purchased the rice ball 14
As shown in Fig. 3, when eating, by grasping the rice ball 14 and applying force to separate the filling and opening part 4.5, the separation part 6 of the inner bag 2 and outer bag 3 can be easily separated and removed. Then, the filling/unsealing portion of the packaging material 1 is opened.

Therefore, by pulling the cut-off part 9 at the tip of the lower end, only the cut-off part 9 of the outer bag 3 is removed by the cut-out part and separated. The distal end of this aspect of the bag 2 is also pulled downward, so that an opening is formed at the distal end of the outer bag 3, the cutoff section 9 is separated, and the inner bag 2 is pulled downward within the outer bag 3. The outer bag 3
Due to the lubricity of the material, the rice ball slides against the rice ball 12 on the inside and the seaweed 10 on the outside, and is gradually pulled out from the opening.

In this case, the outer seaweed 10 is not left inside the outer bag 3 and is not deformed, but gradually becomes attached to the inner rice ball 12 and becomes wrapped around it.

Then, when the inner bag 2 is completely pulled out from the opening at the tip of the outer bag 3, the rice ball 16 becomes a regular rice ball with seaweed 10 wrapped around the outside of the rice ball 12, as shown in FIG. You can get it.

In this case, when eating the rice ball 16, the outer bag 3 may be left on the outside of the rice ball 16, or it may be removed. Of course, when the rice balls 16 are gradually eaten from the filling/unsealing part, the remaining rice balls 16 can be wrapped and stored in the outer bag 3 if necessary.

The types from manufacturing to feeding shown in FIGS. 7 to 14 above are described for the rice ball shown in FIG. 6, but the inner bag 2 of the rice ball packaging material 1 shown in FIG. With the filling opening section 4 open and the rice ball outer bag 12 filled, a second welding seal 1 is applied to the filling opening section 4.5.
3. Instead, as shown in FIG. 5, the rice ball 11 is made into a sealed rice ball 11 that is folded back and a point sticker 15 such as a label with appropriate seaweed is attached to the outer surface of the outer bag 3 and pasted and temporarily fixed. Also good.

It goes without saying that the embodiment of the invention of this application is not limited to the above-mentioned embodiments. For example, in the rice ball 14 in the state shown in FIG. Various modes can be adopted, such as temporarily fixing with a seal 15.

<Effects of the Invention> As described above, according to the invention of this application, in a rice ball wrapped in seaweed that is basically wrapped with a rice ball packaging material made of a soft resin sheet such as soft vinyl, the rice ball packaging material is used before filling the rice ball with rice. By inserting seaweed between the inner bag and the outer bag and sealing the space between them, the path from the material stage to the filling of rice balls is complicated, and it also takes a long time over time. Even when necessary, the seaweed that is the lifeblood of rice balls can be kept fresh without absorbing moisture, and since it is not exposed to the outside air, there is no infiltration of germs. Since the rice balls are not touched by hands during the process, their freshness and flavor are maintained, as well as sanitary conditions.Furthermore, the process from manufacturing and displaying the rice balls to distributing them to consumers and eating them is completely controlled. It is possible to maintain a dry and sealed state, and therefore, even when the consumer finally consumes it, the excellent effect is that the texture and flavor are maintained.

This not only preserves the flavor and texture, but structurally, the so-called seaweed is always interposed between the inner and outer bags, so it is protected from impact and is protected against breakage. There is no risk of tearing, and therefore, an excellent effect is achieved in that the product value can be sufficiently maintained.

Therefore, due to the design, the filling and opening parts of the inner bag and outer bag are
Alternatively, since the seal is welded and sealed three times, an excellent effect is achieved in that the sanitary condition against the outside air is more reliably maintained.

Furthermore, after the inner bag of the rice ball packaging material for rice balls is filled through its filling/unsealing part, the filling/unsealing part of the rice ball packaging material is folded back and fixed on the outside of the outer bag with a point seal or the like. This greatly simplifies the work, reduces costs, and also allows the consumer to easily open the rice ball packaging material when eating the rice ball.

In such an embodiment, it is extremely advantageous if the manufacturing location and the selling location are close to each other.
