Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a packaging bag for rice balls that is coated with rice and seaweed separately and is displayed and sold at a store.

(Prior art) As a conventional packaging bag of this type, the 10th
As shown in the figure, a synthetic resin film 10 was folded back by about one-third to form a seaweed covering part 10', and both sides thereof were heat-sealed b, b to provide a seaweed container part B. In this device, a piece of seaweed is inserted into the seaweed container B, rice is placed on the seaweed covering part 10', and the rice is folded and wrapped along the outer shape of the rice. Therefore, although the seaweed and rice can be coated separately and the flavor of the seaweed can be maintained until the time of eating, the seaweed must be manually inserted one by one into the seaweed container prior to packaging, which is unsanitary. At the same time, it was very troublesome. Furthermore, when eating the seaweed, the seaweed is held in the hand, pulled out, and then wrapped around the rice, making it unsanitary and unsuitable for eating in places where there are no towels or water for washing hands.

(Problems to be Solved by the Invention) The problems to be solved by the invention are that there is no need for a separate process to insert the seaweed, the seaweed can be stored at the same time as the bag is made, and the seaweed and rice can be mixed together when eating. To obtain a packaging bag for rice balls in which seaweed can be wrapped around rice without touching it directly.

(Means for Solving the Problems) The present invention involves folding back a base film having heat-sealing properties on at least one side from both ends with the heat-sealing side facing inside, and then folding the ends together approximately in the center. The widths are overlapped as appropriate, one folded piece is used as a covering film, the other folded piece is used as a covering film, and the left and right edges of the covering film and the covering film are heat-sealed with the left and right edges of the base film. At the same time, the heat-sealed portion is provided with protruding seal portions that protrude inward at several locations to accommodate the seaweed inside.

(Function) According to the present invention, rice is placed on the covering film, a packaging bag is folded along the outer shape of the rice, and the seaweed and rice are covered separately and sold.

(Example) An example of implementing the present invention will be described based on the drawings. Reference numeral 1 indicates a base film having heat-sealability on at least one side, such as a polyolefin-based synthetic resin film (polyethylene film, polypropylene film, modified films thereof, etc.). ), single or modified films of vinyl chloride-based, polyamide-based, polyester-based, or polystyrene-based synthetic resin films, or composite films such as laminated films or composite films of these, forming one or both sides. There are also coated films and part-coated films in which one or both sides of various synthetic resin films that do not have heat sealability are coated with a substance that has heat sealability. This base film 1 is folded back from both ends with the heat-sealing surface facing inside, and the ends are overlapped approximately at the center by an appropriate width, with one folded piece 1' serving as a covering film and the other. Use the folded piece 1'' as a coating film. Sandwich a piece of seaweed between the base film 1, the coating mounting film 1', and the coating film 1", and heat seal the left and right edges to be opened, a and a, respectively. Then close the bag to obtain a packaging bag containing the seaweed.

A' is a protruding seal portion, and by providing several protruding seal portions, it is possible to prevent the seaweed from moving within the packaging bag, thereby preventing damage to the seaweed.

The packaging bag formed in this way has a coating mounting film 1'
Place rice on top, fold the bag sequentially along the outer shape of the rice, such as a triangle or round shape, to wrap the rice in it, then attach and fix the end portion with tape or the like and display it at a store. Offered for sale. still,
When the base film 1 has heat-sealing properties on both sides, the end portions may be fixed by partial sealing such as dot sealing instead of tape or the like.

Next, to explain the procedure for eating rice balls packaged using such a packaging bag, first, peel off the tape etc. and unfold the packaging bag until it reaches the state shown in Figure 4, and then open the rice ball near the center. Put your hand on the overlapping part of the sheets and peel off the covering film 1'' to expose one half of the seaweed.Next, as shown in Fig. 5, remove the covering film 1' on which the rice is placed. Fold back the base film 1 and move the rice bowl inverted onto the exposed nori seaweed A, and fold back the base film 1 and the covering film 1' back to their original positions as shown in Fig. 6.Now the rice bowl is , it was placed on one half of the nori sheet without touching it at all.Next, as shown in Figure 7, the covering mounting film 1' was peeled off to expose the other half of the nori sheet. ,
As shown in Figure 8, if you break the seaweed in half along with the base film 1,
It is possible to wrap the seaweed around the rice bowl without touching the rice bowl and the seaweed bowl at all. Normally, you fold back the base membrane 1 in half as shown in Figure 9, take out the rice ball, and eat it, but if you don't have a towel or hand-washing water, hold it in your hand as shown in Figure 8 and put it in your mouth. If you carry it and eat it, you can eat it without touching it at all, making it hygienic.

(Effects of the invention) According to the invention, a base film having heat-sealability on at least one side is folded back from both ends with the heat-sealability side facing inside, and the ends are overlapped by an appropriate width near the center. Then, one folded piece is used as a coating film, the other folded piece is used as a coating mounting film, and the left and right edges of the coating film and the coating mounting film are heat-sealed with the left and right edges of the base film to form an opening. At the same time, the two sides of the bag are closed, and at the same time, protruding seal parts are provided at appropriate locations on the heat seal part to store the seaweed inside, so the seaweed can be stored at the same time as the bag is being made, unlike conventional products. Since there is no need to manually insert the seaweed one by one after bag making, the work time can be significantly shortened and it is also sanitary.

Further, since it is sufficient to simply perform folding and heat-sealing on one film, the molding process is extremely simple and can be supplied at low cost.

Furthermore, since the seaweed is stored in a packaging bag that is closed on two sides by a folded section and the remaining two sides closed by a heat-sealed section, moisture may enter from the edges of the packaging bag during transportation or display at a store. There is no risk of the seaweed becoming damp.

Also, when eating, you can wrap the rice with seaweed to make onigiri without touching the rice or seaweed at all, so it is hygienic, and if necessary, you can eat the onigiri without touching the rice ball directly. It is also suitable for eating in places where there are no towels or water for washing hands.

Furthermore, the protruding seal portion that protrudes inward from the heat seal portion can prevent the seaweed from moving within the packaging bag, so there is no risk of damage to the seaweed.

Therefore, the present invention can achieve the intended purpose.
