Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a packaging bag for a rice cake.

[0002]

[Prior art]

 Recently, rice balls and seaweed are sold at convenience stores, etc., using packaging bags that can separate rice and laver with a plastic film, and are sold as rice balls and seaweed that are not in contact with each other. There are many. The purpose of this is to prevent the seaweed from getting wet and unpleasant taste when the seaweed and rice are wrapped in contact with each other.Remove the plastic film when eating the rice ball, and wrap the rice ball with seaweed. It is something to eat.

[0003] In the case where a grip is packaged using the above-mentioned packaging bag, in most cases, the package is opened to take out the grip as follows.

First, the opening tape is pulled to cut the outer surface film into two pieces. Next, one surface film is peeled off, and half of the rice for rice and seaweed, which have been separated and packaged, are exposed in a state where the seaweed is wrapped around the rice for rice. Next, the other surface film is peeled off, and the other half of the rice and the seaweed are exposed in a state where the seaweed is wrapped around the rice, so that a finished rice ball wrapped with seaweed is obtained. Things.

[0005] However, the above-mentioned method has a problem that, when the packaging bag divided into two parts is pulled in the opposite direction to take out the rice ball, the rice ball is broken into two. In other words, the rice for rice cake and the back film for the interior are sticky, so that the back film and rice for rice rice are easy to adhere, and when the packaging bag is pulled with both attached, the rice for rice rice becomes two. The problem of cracking had occurred.

[0006] A packaging bag for solving the above problem is disclosed in Japanese Utility Model Laid-Open No. 63-86085. 8 is a perspective view as seen from the back of the packaging bag, FIG. 9 is a cross-sectional view taken along the line IX-IX of FIG. 8, and FIG. 10 is a cross-sectional view showing a state in which the grip is packaged using the packaging bag. The packaging bag 21 is provided with a rectangular surface film 23 provided with an opening tape 22 from a center portion in the width direction toward a center portion of one end opposed thereto, and a folded portion provided on each outer side. At the center of 23, two rectangular back films 24 and 25 which are overlapped in the same direction as the opening tape 22 are overlapped, and the periphery except the portion where the opening tape 22 is provided is overlapped. Are thermally fused to form a thermally fused portion 28. Therefore, at the portion where the back film 24 and the back film 25 of the packaging bag 21 overlap, as shown in FIG. 9, the folded portions 26 and 27 which are respectively folded outward are formed.

As shown in FIG. 10, a method of packaging a hand grip using the packaging bag 21 is to store the laver 29 between the front film 23 and the back films 24 and 25 and hold the back films 24 and 25. The rice balls 30 are wrapped in a packaging bag 21 while being in contact with the rice 30 for cooking.

When the grip is wrapped using the packaging bag 21, the opening tape 22 is pulled to divide the front film 23 into two parts. When one of the front films is pulled, the back film 24 is pulled together with the one front film. However, at this time, since the folded portion 26 is peeled off from the rice for rice-grip 30 so as to be turned over, the back film 24 does not adhere to the rice for rice-grip 30. Therefore, when the rice cake is wrapped using the packaging bag 21, the rice rice for rice cake can be taken out of the rice cake package in a state of being wrapped in laver without breaking the rice rice cake for rice rice into two.

However, the conventional packaging bag 21 is insufficient in that the rice for rice cake and the back film are smoothly peeled off when the rice cake package is opened. That is, the conventional packaging bag 21 employs a configuration in which the folded portions 26 and 27 are provided in the portion where the back film 24 and the back film 25 overlap, and the folded portion is peeled off so as to be flipped from the rice for rice. Therefore, there was a problem that the folded portion was not always turned smoothly.

[0010] The conventional packaging bag 21 is also insufficient in that the seaweed is kept dry by isolating and storing the seaweed from the moisture contained in the rice for rice cladding. That is, the conventional packaging bag can separate and package rice for rice and nori, but rice for rice and seaweed are separated by the two back films 24 and 25. I was just doing. Therefore, the moisture of the rice for rice balls 30 only passes through the space 30 formed between the back film 24 and the back film 25, and the water immediately reaches the laver. Was inadequate.

[0011]

[Problems to be solved by the invention]

 The present invention protects a rice ball from damage when the packaging bag is divided into two parts and removes the rice ball from the rice bag packaging body, and can be opened more smoothly than a conventional packaging bag. An object of the present invention is to provide a packaging bag for a rice ball that can effectively protect the laver from the moisture contained in the rice ball and keep the laver in a dry state.

[0012]

FIG. 1 is a front view of a packing bag for rice balls according to the present invention, FIG. 2 is a rear view of the packing bag for rice balls, and FIG. 3 is a cross-sectional view taken along line III-III of FIG. 1 to 3, reference numeral 1 denotes a packing bag for holding rice (hereinafter, referred to as a “packaging bag”); 2, an opening tape; 3, a front surface film; Reference numeral 16 denotes a sealing portion, 16 denotes one edge of the surface film 3 in the vertical direction, and 17 denotes the other edge of the surface film 3 in the vertical direction.

As the material of the front film 3 and the back film 4, any material can be used as long as it is a plastic film for food packaging. Polyolefin plastic films such as polypropylene and polyethylene are preferable, and polypropylene is inexpensive. It is particularly preferable because it has excellent properties such as oxygen barrier properties. The thickness of the surface film is preferably from 10 to 40 μm, more preferably from 15 to 30 μm from the viewpoint of ease of opening and economy. The front film 3 and the back film 4 are preferably transparent or translucent from the viewpoint that the inside can be seen, but may be colored.

The shape of the surface film 3 is preferably a rectangle from the viewpoint that the rice cake can be packed without waste, but is not limited to the rectangle, but may be a trapezoidal shape or the like. The size of the surface film 3 is appropriately selected according to the size of the rice ball.

The opening tape 2 is laminated on the back surface of the front film 3 along the longitudinal direction at the center in the width direction of the front film 3. The opening tape 2 is preferably a belt-shaped polypropylene or polyester having a width of 3 to 20 mm, and more preferably stretched polypropylene or polyester. The opening tape 3 is preferably colored. However, the material and dimensions of the opening tape 2 are not limited to these, and the laminating method is not limited to heat fusion, and an adhesive may be used. Although not shown, notches are preferably provided on both sides of the upper edge portion of the surface film 3 where the opening tape 2 is laminated, in order to facilitate opening.

As for the material of the three back films 4, 5, and 6, it is preferable to use a polyolefin resin film as in the case of the front film 3, and it is particularly preferable to use a polypropylene film.

The three back films 4, 5, and 6 have a shape that can be superimposed on the front film 3. When the front film 3 is rectangular, the vertical length is equal to the vertical length of the front film 3. Preferably, they are equal rectangles. However, in the present invention, the shape is not limited to a rectangle, but may be another shape corresponding to the shape of the surface film 3. Further, as long as the three back films 4, 5, 6 are alternately overlapped, the length in the width direction can be changed. It is preferable that the vertical edge of each back film in the portion where the three back films 4, 5 and 6 alternately overlap is linear, but it can also be triangular or arcuate. .

The first back film 4 is superimposed on the back surface of the front film 3 with a width extending from one longitudinal edge 16 of the front film 3 to a position beyond the opening tape 2 at the center in the width direction. . The second back film 5 is polymerized with a width extending from the other edge 17 in the longitudinal direction of the front film 3 to a position beyond the opening tape 2 at the center in the width direction. The third back film 6 has a width extending from the one edge 16 in the longitudinal direction of the front film 3 to a position beyond the opening tape 2 in the center in the width direction, from the top of the first back film 4. The film 3 is polymerized.

Since the three back films 4, 5, and 6 are configured as described above, the first back film 4 and the second back film 5 have a width as shown in FIG. The space 10 is formed so as to overlap with each other along the longitudinal direction at the center in the direction. The second back film 5 and the third back film 6 overlap with each other along the vertical direction at the center in the width direction to form a space portion 11. The length in the width direction of the overlapped portion is not particularly limited, but is preferably 5 to 20 mm from the viewpoint of preventing the passage of moisture and preventing damage to the rice cake when peeling the packaging bag 1.

The peripheral portion where the front film 3 and the three back films 4, 5, 6 are superimposed has three back films at the upper and lower peripheral portions of the opening tape 2 and the central portion in the width direction. The seal portion 7 is provided except for the overlapping portions 4, 5, and 6. It is preferable that the peripheral seal portion 7 is formed by heat fusion. However, the present invention is not limited to this.

Since the packaging bag 1 of the present invention is formed in a bag shape as a whole by providing the seal portion 7, the back film 4 and the space 16 formed by the back film 5 and the front film 3 are formed in the bag. Seaweed can be stored.

FIG. 4 is a cross-sectional view showing a state in which rice balls are packaged using the packaging bag 1 of the present invention. In FIG. 4, numeral 8 denotes laver and numeral 9 denotes rice for rice balls. When the seaweed 8 and rice 9 for rice wrapping are packed using the packaging bag of the present invention, the water contained in the rice 9 reaches the seaweed 8 as shown in FIG. It must pass through the space 10 formed and the space 11 formed by the back film 5 and the back film 6. Therefore, when the moisture contained in the rice passes through the space formed by the two backing films and reaches the laver immediately, the laver is protected from the moisture of the rice more reliably than the conventional wrapping bag for nigiri. It can be kept dry.

Next, an example of a method of packing rice balls using the packaging bag 1 of the present invention will be described with reference to FIGS. It is efficient and preferable to store the laver in the space 16 formed by the front film 3, the back films 4, 5 and the sealing portion 7 in the process of manufacturing the packaging bag 1.

The packaging bag 1 is placed with the surface film 3 facing down, and rice for rice rice 9 is placed on the packaging film 1 so as to be offset to the lower end side in the longitudinal direction of the packaging bag 1 as shown in FIG. As shown in FIG. 5, both corners 11, 12 at the lower end of the packaging bag 1 are bent toward the rice 9, and both corners 11, 23 are further bent toward the side surfaces of the rice 9. Next, the upper end of the packaging bag 1 in the longitudinal direction is bent toward the surface 17 of the rice 9, and the upper corners 13, 14 are drawn on the back surface (the surface opposite to the surface 17) of the rice 9. 5 and then sealed with a label 15 from above as shown in FIG.

A method of taking out a rice ball packed using the packaging bag 1 will be described. The opening tape 2 is pulled to cut the surface film 3 into two pieces. At this time, the back film 4 and the back film 6 are sealed on only half of the front film 3, and the back film 5 is sealed on only the other half of the front film 3, so that the packaging bag 1 is divided into two as a whole. Be cut off.

Next, pulling one surface film of the above-mentioned divided packaging bag 1, for example, the surface film on which the back films 4 and 6 are sealed, pulls the back film as shown in FIG. The films 4 and 6 are pulled together with the front film, the back film 6 slides and moves along the rice 9 for rice picking, the back film 4 slides and moves along the laver, and half of the rice 9 is wrapped in the laver 8 Exposure with Next, when the other side of the packaging bag 1 is peeled off in the same manner, half of the remaining rice 9 is exposed while being wrapped in the laver 8, and a rice ball wrapped with the laver 8 is completed.

[0029] The packaging bag of the present invention can also be used for wrapping rice balls, which are made by wrapping ingredients other than laver, for example, kelp, around rice for rice balls.

[Effect of the invention]

 As explained above, the packaging bag for a hand grip of the present invention is composed of a front film on which an opening tape is laminated in the center in the width direction and three back surfaces superposed on the back surface of the front film. The back film of the first film is polymerized on the front film with a width extending from one longitudinal edge of the front film to the position beyond the opening tape at the center in the width direction, and the second back film is formed. Is polymerized with a width extending from the other edge in the longitudinal direction of the front film to a position beyond the opening tape at the center in the width direction, and the third back film is formed on one edge in the longitudinal direction of the front film. From the top of the first backing film with a width extending from the opening tape to the position beyond the opening tape at the center in the width direction, and the first sheet along the lengthwise direction at the center in the width direction. The top and bottom peripheral portions of the opening tape are located at the periphery where the top film, second back film, and third back film alternately overlap, and the top film and the third back film are superimposed. A configuration is adopted in which a seal portion is provided except for the overlapping portion of the three back films at the center in the width direction. Therefore, there is a problem that the folded part may not be able to be smoothly turned, unlike the conventional handbag, because the three backing films only overlap at the center of the handbag. It can always be opened smoothly without any problems.

[0031] In addition, the packing bag for a handgrip of the present invention has two spaces by alternately overlapping three backing films. Effective protection from the moisture contained in rice for rice making can help keep the seaweed dry.

In addition, when the packaging bag of the present invention is used, after pulling the opening tape to divide the packaging bag into two pieces, the grip is not broken into two pieces when one of the packaging bags is peeled off. Can be easily removed from the packaging bag.
