DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a packaged triangular rice ball, and more particularly to a packaged triangular rice ball that can be kept in a state where it does not come into contact with outside air.

[Prior art and problems to be solved]

Generally, there are various packaging materials used for rice balls that are packaged and sold at convenience stores and the like. An example thereof is shown in FIGS. 8 and 9.

That is, this packaging material has a film 21 on the front surface side and two films 22a, 22b on the back surface side that overlap each other at the central portion of the film 21 on the front surface side, and their peripheral portions are thermally bonded. 25 and is formed into a bag-shaped packaging material.

In this case, the film 21 on the front surface side and the films 22a, 22b on the back surface side are easily heat-bonded, but the film on the back surface side
22a and 22b are treated so as not to be heat-bonded to each other.

Then, when using the packaging material, first, between the film 21 on the front surface side and the films 22a, 22b on the back surface side, for example, the seaweed 26 or kelp that is a winding material is stored, and the back surface side It is commercially available as a triangular rice ball in which rice balls 27 for a rice ball, which is formed into a triangular prism shape, is wrapped on the upper surfaces of the films 22a and 22b, and the ends of which are wrapped with a label 28 or the like.

When eating this packaged triangular rice ball, first peel off the label 28 and the like, place the rice 27 for the rice ball on the film 22b on the one back side, and the overlapping part of the film 22a on the other back side. To remove the seaweed 26 and the like from the film 21 on the front side by pulling and pulling, move the rice 27 for rice balls to the upper surface of the exposed seaweed 26, and this time, the film 22b on the back side of the one side. The end portion of the rice ball is picked up and pulled to peel it from the film 21 on the surface side to expose the rest of the seaweed 26 and the like, and the rice ball 27 for rice balls is wrapped in this portion to complete the rice ball.

In the packaging material as described above, it is as shown in Fig. 10 when the rice for rice balls is wrapped, and the packaging material is folded at the three corners. Since there are gaps 29 in each of them, they are in a state of being formed.

Therefore, there is a possibility that moisture may enter the inside through the gap 29 and a small insect may enter in some cases, which is a sanitary problem.

This invention provides a packaged triangular rice ball that can prevent rice and seaweed located inside from coming into contact with the outside air to prevent moisture from entering, and also prevent insects from entering. The purpose is to

[Means for Solving the Problems]

In order to solve the above-mentioned problems, while forming a square shape, the film on the surface side which is subjected to a treatment for opening in the central portion, the central portion overlaps with each other, and the peripheral portion excluding this portion is the surface. On the backside film, which is composed of two backside films adhered to the backside film and accommodates a roll such as seaweed between the frontside film and the backside film. After arranging a triangular rice ball on the half part, fold the lower half part and bring the film on the back side into contact with both sides and the bottom surface of the rice part, and fold both corners of the lower half part on both inclined surfaces of the rice. After making contact, both corners of the upper half were also folded so as to overlap with both corners of the lower half, and both corners of the upper half contacted the lower half covering one side of the rice. In this state, they are polymerized with each other, and in this state, label both corners And fixed to the lower half in, but where the configuration of sealing the rice further 3 a gap corners were sealed, respectively.

Further, the unsealing treatment is a tape provided over the entire width on the film side on the back surface side of the film on the front surface side, or a U-shaped cut facing the unsealing direction provided on the film on the front surface side. Alternatively, it has a structure in which a tongue portion provided on both sides in the width direction of the film on the front surface side and a notch cut inward from both sides of the tongue portion.

[Action]

By adopting the above means, this device has three corners sealed in a state where rice for rice balls and rolled material such as seaweed and kelp are packed, so that moisture or insects may enter inside. Can be reliably prevented. In addition, the front side film is divided into two parts through the unsealing treatment applied to the front side film, and then the two front side films are removed to the left and right so that each of the two back side films is also separated. It is divided into right and left, so the rolled material such as seaweed and kelp stored between the film on the front side and the film on the back side is wrapped around rice to complete the rice ball, but this rolled material is in a dry state. The flavor of the roll,
You can complete delicious rice balls without losing the scent.

〔Example〕

 An embodiment of the present invention shown in the drawings will be described below.

FIG. 1 and FIG. 2 show an embodiment of a packaged triangular rice ball according to the present invention. In the packaging material used in this embodiment, a rectangular biaxially oriented polypropylene film is used on the surface side. Adhesive tape 3 for opening of about 1.5 mm width is adhered to the center of the short side of the film 1 on the surface side in parallel with the long side so that it can be easily pinched around the end. Cuts 4 and 4 are provided in the tape, and the thermoadhesive resin 5 is applied to the peripheral portion of the unsealing tape except for the peripheral portion thereof so that the film 1 on the front surface side is not hindered from being cut at the time of unsealing.

Then, on the back surface of the film 1 on the front surface side as described above, the films 2a, 2b on the back surface side composed of two sheets of high-density polyethylene film, with their central portions overlapping each other by 1 cm or more, and It is positioned so as to be located in the central portion of the film 1 on the side, and the peripheral portion is thermocompression bonded, and the peripheral portion between the film 1 on the front surface side and the films 2a, 2b on the rear surface side is adhered to form a packaging material. Form.

When the triangular rice ball rice 7 is packed using the packing material formed as described above, first, the film 1 on the front surface side is used.
3 is shown in FIG. 3 at the upper part of the upper surface of the backside films 2a and 2b, which is a roll, for example, laver 6 is put in the space formed between the backside films 2a and 2b. In this way, the triangular rice ball rice 7 is placed so that the top is located on the tape 3 for opening provided on the film 1 on the front side.

Next, after bending the lower half of the packaging material, fold both corners of the lower half to make contact with both inclined side surfaces of the rice for triangular rice balls, and then to the upper half of the packaging material. After the corners are bent toward the front side and both corners of the lower half are folded and folded, the label 9 is fixed.

Further, in this state, as in the case shown in FIG. 10, the gaps 29 remain at the three corners, so the three corners are heat-sealed 15 and sealed as shown in FIG. To do.

If you want to eat something packaged as above, first,
The film 1 on the surface side can be easily cut by pinching and pulling the end portion of the opening tape 3 located at the top,
After that, if you hold both sides of the cut film 1 on the front side and pull it to the left and right one by one, only the peripheral portions of the film 1 on the front side and the films 2a, 2b on the back side are heat-bonded, The packaging material can be easily pulled out, and the rolled seaweed 6 can be wrapped around the entire circumference of the rice 7 for rice balls, and a so-called triangular rice ball wrapped with seaweed can be completed and eaten. be able to.

The film 1 on the front surface side is not limited to biaxially oriented polypropylene, and may be any polyolefin film.

5 and 6 show another example of the packaging material used for the packaged triangular rice ball according to the present invention.

In this example, only the procedure for opening is different and the other parts are the same, so the same numbers are assigned and detailed description is omitted.

Unlike the above-mentioned packaging material, the packaging material shown in this example does not use a tape as a procedure for opening, and is provided with a U-shaped notch 10 that faces the opening direction.
A streak 11 for dividing the film 1 on the front surface side is provided on the surface 10, and a notch 12 is formed integrally with them.

Then, the rice 7 for triangular rice balls is wrapped in the same manner as described above, the label 9 is attached to the notched portion 12 to hold it in the wrapped state, and then the three corners are heat-sealed and hermetically sealed.

Then, when the label 9 is peeled off at the time of opening, the inside of the notch 10 is separated integrally with the label 9, and the label 9 is further circulated so that most of the film 1 on the front surface side is divided into two along the notch. Since the notch 10 is provided with the streak 11, the remaining part which is not divided into two is divided into two via the streak 11 when the film 1 on the front side is pulled left and right.

This makes it possible to easily complete a triangular rice ball wrapped with seaweed.

FIG. 7 shows still another example of the packaging material used for the packaged triangular rice ball according to the present invention. In this example, the same members as those in the above example are designated by the same reference numerals. Detailed description is omitted.

In the example shown in this example, unlike the examples shown in the above-mentioned examples, a uniaxially stretched film is used as the film 1 on the front surface side, the longitudinal direction is the stretching direction, and the tongue portion 13 is provided in the central portion. Notches 14 on both sides of the tongue part 13,
14 is provided.

Even in this case, the seaweed 26 or the like is located between the film 1 on the front surface side and the films 2a and 2b on the back surface side, and the rice 7 for triangular rice balls is located on the films 2a and 2b on the back surface side. After packaging, the three corners are heat-sealed and sealed.

At the time of unsealing, if the tongue portion 13 is pinched and pulled, the film 1 on the surface side is a uniaxially stretched film, so that it can be easily torn without a tape for unsealing,
The front-side film 1 can be divided into two parts. Therefore, by pulling the front-side film 1 left and right, the seaweed 6 etc. stored between the front-side film 1 and the back-side films 2a and 2b are rice balls. It can be wrapped around rice for cooking 7 to complete a rice ball.

[Effect of device]

As described above, according to the present invention, the rice is positioned on the back side and folded, and then the three corners are sealed and packaged, so that the inside can be reliably sealed and there is a risk that moisture or insects may enter. It is surely preventable and hygienic. Also, after winding using the procedure for opening, pulling to the left and right, wrap the rolled material such as seaweed stored between the film on the front side and the film on the back side on the triangular rice ball for triangle rice balls. You can complete a rice ball, but since there is no risk of the rolled material such as seaweed getting damp, you can keep it in a dry state for a long time without damaging the flavor and aroma of the rolled material, and a delicious triangular rice ball is completed. It has an excellent effect of being able to do.
