TECHNICAL FIELD OF THE INVENTION
The present invention relates to a package of processed rice food in which a sheet-like food such as a sheet of laver and a processed rice food such as a triangular rice ball are packaged in a separated state, and in particular, cooked with high-grade ingredients and fluffy. The present invention relates to a package of processed cooked rice food which is suitable for packaging a processed rice cooked softly.
[0002]
[Prior art]
Onigiri rice balls sold at convenience stores etc. are packed in a package that stores rice balls and laver separately to prevent the laver from getting wet due to the moisture of the rice balls during transportation or display. Have been.
[0003]
In this package, as shown in FIG. 5, an outer film 110 and two inner films 120, 120 sandwich a sheet of laver 1. The outer film 110 is formed in a rectangular shape having a size capable of accommodating, for example, a triangular rice ball 2. A cut tape 112 is adhered on a center line connecting the center portions 111 at both ends of the outer film 110, and the outer film 110 can be divided into two by pulling the cut tape 112.
[0004]
On the other hand, the two inner films 120, 120 have inner ends 121, 121 overlapping on the center line of the outer film 110, so that they can be separated in the width direction. The outer film 110 and the inner films 120, 120 sandwich the laver 1 therebetween, and the peripheral portions 113, 123 excluding the center portions 111, 122 at both ends are sealed by, for example, heat.
[0005]
In such a package, the onigiri 2 is placed on the inner films 120, 120, and both the films 110, 120, 120 and the laver 1 are folded according to the shape of the onigiri 2, and the onigiri 2 is wrapped around. Then, a label (not shown) displaying product information or the like is affixed to a region including both corners overlapping in a state where the outer film 110 is exposed. When the cut tape 112 is pulled, the outer film 110 is divided into two parts. When the outer film 110 and the inner films 120, 120 are further pulled in the width direction, each inner film 120, 120 is pulled from between the laver 1 and the rice ball 2. It can be eaten in a state where the seaweed 1 is wrapped around the rice ball 2 after being pulled out.
[0006]
In order to prevent the inner film overlapping at the inner end from falling apart in the process of being conveyed to a predetermined position on the automatic packaging line, both ends of the inner end of the inner film are heat-sealed to the peripheral edge of the outer film. Japanese Patent No. 2990064 discloses a package joined together by the above method.
[0007]
[Patent Document 1]
Japanese Patent No. 299,964 [0008]
[Problems to be solved by the invention]
By the way, in the conventional rice ball 2, rice is pressed into a mold and molded, and is gripped relatively hard. Therefore, in the conventional package of processed rice food, including the package disclosed in the specification of Japanese Patent No. 2990064, the outer film 110 and the inner films 120, 120 are folded according to the shape of the rice ball 2, and the packaging is performed. Have been.
[0009]
However, in recent years, rice balls 2 using high quality ingredients that are becoming popular have been softly grasped softly, so that the package cannot be bent according to the shape of the rice balls 2 as in the past, or it is likely to be bent. Then, the rice balls 2 are hardened and packaged, and the quality is impaired. Furthermore, if the rice balls 2 using high-quality food are packaged in the same packaging material as the conventional ones, they cannot be visually distinguished from the generally hardly held rice balls 2.
[0010]
Therefore, an object of the present invention is to provide a package of processed rice food in which rice balls, which are softly gripped using high-grade foods, can be packaged while maintaining a fluffy feeling.
[0011]
[Means for Solving the Problems]
The processed rice cooked food package according to the present invention is folded into two, an outer film having a cut line set in the width direction of the bent portion, and an outer film excluding the bent portion of the outer film. And two intermediate films superimposed on the inner surface of the inner film, and an intermediate film adhered to the bent portion of the outer film and having both side edges overlapping the inner ends of the respective inner films except for corner cut portions provided on four sides. The outer peripheral portion of the outer film and the three peripheral portions except for the inner end of each inner film are sealed, a sheet-like food is sealed between the outer film and the inner film, and each inner film is formed into a block. In the state where the outer film is folded in two so as to be joined to the processed rice food, the edges of the inner film are sealed, and the edges of the outer film to be joined by the corner cut portions provided in the intermediate film are joined together. Shi It is characterized by being Le.
[0012]
According to the package of the processed rice food, the outer film is folded in two so that each inner film is joined to the block of processed rice food, the peripheral portions of the inner film are sealed, and the corner cut portion is formed in the intermediate film. As a result, the peripheral portions of the outer films to be joined are sealed with each other, so that the processed cooked rice food is packaged in a state of being stored with a margin, and the soft gripping softness is maintained.
[0013]
By overlapping the inner end of each inner film with the side end of the intermediate film, the sheet-like food enclosed between the inner film and the outer film is completely converted from cooked rice cooked food packed between the two inner films. And it is possible to make it difficult to absorb the moisture of the cooked rice food.
[0014]
Then, the outer film is cut along the cutting line, and the bent portion of the outer film is cut off, thereby pulling out the inner film integrated with the outer film from between the sheet food and the cooked rice food, and processing the cooked rice. The food can be taken out from between the inner films while being sandwiched between the sheet-shaped foods. In addition, since the corner cut portions are provided on all sides of the intermediate film, the four sides of the intermediate film are not sealed to the peripheral portion of the inner film, only the peripheral portions of the outer film are sealed, without cutting the intermediate film, The outer film can be easily cut from the end of the planned cutting line, and the intermediate film attached to the bent portion of the outer film can be separated from the other outer film.
[0015]
In the package of processed rice food, the outer film may be a composite material obtained by joining and integrating a plastic material disposed on an inner surface side and a paper material disposed on an outer surface side. According to the package of the processed cooked rice food, not only the high quality feeling is exhibited but also the rigidity is increased by the outer paper material, so that the packaged processed rice food can be prevented from being crushed.
[0016]
Further, in the package of the processed rice food, the bent portion has a width substantially equal to the thickness of the processed rice food, two cut lines are set with the width, and a strip is formed along the cut line. Is preferably attached. According to the package of processed rice food, two lines to be cut are set with a width substantially equal to the thickness of the processed rice food, and two strip-shaped cutting means or two thin strips along the line to be cut. By attaching a single strip-shaped cutting means having a large width between the lines to be cut, the outer film can be easily and reliably torn from one end to the other end with the width of the cooked rice food.
[0017]
In the package of processed rice food, it is preferable that the inner film is provided with a folded portion that is folded at an inner edge on a surface opposite to the outer film. By having a folded portion that is folded back to the opposite surface from the outer film at the inner end of the inner film, the folded portion is joined to the cooked rice food, and the inner edge is from between the inner films without pulling near the bottom of the cooked rice food Because it can be taken out, processed rice food can be made hard to crack.
[0018]
BEST MODE FOR CARRYING OUT THE INVENTION
One embodiment of a package of processed rice food according to the present invention will be described with reference to FIGS. 1 to 4. The package of the processed cooked rice food of the present embodiment is a rectangular outer film 10 that is large enough to store a block of processed cooked rice food (hereinafter, referred to as “onigiri”) 2 like a triangular rice ball, and is folded in half. And two inner films 20, 20 superposed on the inner surface of the outer film 10 except for the bent portion 11 of the outer film 10. The width of the bent portion 11, that is, the interval between the inner edges 21, 21 of the two inner films 20, 20, substantially matches the thickness of the rice ball 2.
[0019]
Further, the peripheral portion 12 of the outer film 10 and the peripheral portions 22, 22 of the two inner films 20, 20 excluding the bent portion 11 side are sealed by heat or the like, and the outer film 10 and the two inner films 20 are sealed. , 20 are formed with storage portions for storing sheet-like foods (hereinafter, referred to as "seaweed") 1, 1 such as sheet-like seaweed.
[0020]
The cut line 13 is set on the outer film 10. Two lines to be cut 13 are set with the width of the bent portion 11, and a pair of band-shaped cutting means (hereinafter, referred to as “cut tape”) 14, 14 are pasted along the lines to be cut 13, 13. Be worn. However, the cut tape 14 may be a single wide tape stuck between the two scheduled cutting lines 13, 13.
[0021]
In any case, the cut tape 14 is adhered to the inner surface of the outer film 10 so that the outer film 10 can be torn without fail. May be. Further, instead of the cut tape 14, a linear scratch for guiding the tearing direction by a laser or the like may be provided on the planned cutting line 13.
[0022]
When the outer film 10 is folded in two to store the rice balls 2 in the subsequent process, the pair of cut tapes 14 and 14 are sealed at both ends by sealing the peripheral portion 12 of the outer film 10. Although they are joined, the middle part becomes bifurcated and becomes visible at the bottom of the front and back of the rice ball 2 or wraps around the bottom.
[0023]
An intermediate film 30 is adhered to the bent portion 11 of the outer film 10 on the inner surface where the two inner films 20 are arranged. The intermediate film 30 has a width wider than the interval between the two inner films 20, 20, and the side edges 31, 31 overlap the inner ends 23, 23 of the inner films 20, 20, respectively. The laver 1,1 enclosed between the outer film 10 and the laver 1,1 is completely separated from the packaged cooked rice food so as to make it difficult to absorb the moisture of the cooked rice food, and to prevent the rice from being moist. .
[0024]
Corner cut portions 33, 33,... Are provided on four sides of the intermediate film 30. By the corner cut portions 33, 33, when the peripheral portions 22, 22 of the inner films 20, 20 are sealed in a later step, the intermediate film 30 is not sealed by the inner films 20, 20, and The outer film 10 is easily cut from the ends of the planned cutting lines 13, 13 without cutting the intermediate film 30, and the outer film 10 to which the intermediate film 30 is adhered is sealed without cutting the intermediate film 30. Can be separated together with the bent portion 11 of FIG. The corner cut portions 33 can have various shapes such as an L-shape and an arc shape in addition to the oblique cut as shown. Also, by providing the corner cut portions 33, 33..., When the peripheral portion 22 of the inner film 20 is sealed in a later step, both ends of the two cut tapes 14, 14 and the outer film 10 are sealed. The peripheral edges 12 are sealed with each other.
[0025]
Notches 15 are formed on the outer film 10 near each end of the cut tape 14 so that the end of the cut tape 14 can be easily picked. When the notch 15 is also formed on the inner film 20 or the intermediate film 30, the inner film 20 or the intermediate film 30 is also torn from the site of the notch 15, and the two inner films 20 are pulled outward upon opening. At times, the inner film 20 or the intermediate film 30 may remain between the rice ball 2 and the laver 1. However, since the intermediate film 30 is provided with the corner cut portion 33, the notch 15 is formed only in the peripheral edge portion 12 of the outer film 10 where the intermediate film 30 and the inner film 20 are not sealed. Can be.
[0026]
Further, the linear notch 15 is formed in the outer film 10 by folding the outer film 10 in two in a later step, sealing the peripheral portions 22, 22 of the inner films 20, 20, and then forming the outer film 10 in the outer film 10. , 20 can be easily and reliably formed at overlapping positions even if the peripheral portions 22, 22 of the seals are slightly shifted. However, by forming the notches 15, 15 into a shape having a width such as a triangle or a U-shape, the inner films 20, 20 are formed before the three-way sealing, and the inner films 20, 20 are slightly misaligned and sealed. Also, the notches 15, 15 can be made to overlap.
[0027]
The outer film 10, the inner films 20, 20 and the intermediate film 30 are not specified as long as they are plastic films for food packaging, but it is preferable to use low cost, low air permeability polypropylene or the like. . Further, the outer film 10 may be a composite material obtained by joining and integrating a plastic material disposed on the inner surface side and a paper material disposed on the outer surface side. The outer paper material not only provides a sense of quality but also increases the rigidity and makes it possible to prevent the packaged processed rice food from being crushed.
[0028]
And, the inner films 20, 20 are provided with folded portions 24, 24 that are folded back to the opposite surface to the outer film 10 at the inner edges 21, 21 overlapping the respective side edges 31, 31 of the intermediate film 30. Is preferred. When the folded portions 24, 24 of the inner films 20, 20 are joined to the onigiri 2, the inner edges 21, 21 pull near the bottom of the onigiri 2 when the onigiri 2 is taken out from between the inner films 20, 20. And the rice ball 2 can be made hard to break. However, for example, when the inner film 20 is made of a material that is less likely to stick to the onigiri 2 or when the onigiri 2 is cooked so that it is less likely to stick to the inner film 20, the folded portion 24 may not be provided.
[0029]
In order to package the rice ball 2 with the packaged rice cooked food product of the present embodiment configured as described above, the outer film 10 and the inner films 20, 20 whose peripheral edges 12, 22, 22 are sealed in advance are used. Nori 1,1 is stored in the storage section between them. The side end 31 of the intermediate film 30 may overlap the front side of the inner end 23 of the inner film 20 or may enter the back side.
[0030]
Then, the bottom surface of the rice ball 2 is placed on the intermediate film 30, and the outer film 10 is folded in two so that the front and back surfaces of the rice ball 2 are joined to the respective inner films 20, 20, as shown in FIGS. I do. Since the width of the bent portion 11 substantially matches the thickness of the rice ball 2 and the inner edges 21 and 21 of each of the inner films 20 and 20 almost match the bottom of the rice ball 2, the bottom of the laver 1 is Almost coincides with the base of.
[0031]
Then, the three peripheral edges 22, 22 of the inner films 20, 20 which are not on the side of the bent portion 11, the peripheral edges 12 of the outer film 10, which do not seal the inner film 20, and the end 32 of the intermediate film 30. Seal each other with heat. Then, both ends of the cut tape 14 are joined because the corner cut portions 33 are provided in the intermediate film 30, but the intermediate portion is bifurcated into the front and back bottom portions of the rice ball 2, or is separated and separated. Wrap around the bottom of rice ball 2.
[0032]
Then, a notch 15 is formed in a portion where only the outer film 10 is joined. By forming the notch 15 after the outer film 10 is sealed, the notch 15 can be prevented from being displaced.
[0033]
The three sides of the bonded inner films 20, 20 are sealed, so that the rice balls 2 can be wrapped in this package with a margin, so that the rice balls 2 can maintain a soft and soft feeling. . Further, since the inner film 20 and the intermediate film 30 are interposed between the rice ball 2 and the laver 1, the laver 1 does not become wet.
[0034]
Then, in order to eat the rice ball 2, the end of the cut tape 14 is pinched and pulled, and the outer film 10 is torn at the planned cutting line 13. In addition to the notch 15 formed in the outer film 10, the corner cuts 33, 33... Are provided in the intermediate film 30, so that the end of the cut tape 14 is picked and the outer film 10 is cut along the cut line 13. Can be easily torn. Even if the outer film 10 is separated by the thickness of the rice ball 2, the outer film 10 is torn on the cut line 13 because the cut tape 14 is attached to the outer film 10. Further, since the middle portion of the cut tape 14 is forked, the outer film 10 can be torn widely without breaking the laver 1.
[0035]
As described above, when the outer film 10 is torn at the bent portion 11 between the two cut lines 13, 13, the intermediate film 30 is also cut along with the bent portion 11 of the outer film 10 as shown in FIG. Separated from 10. Since the folded portion 24 is provided on the inner film 20, the rice balls 2 sandwiched between the laver 1 and 1 can be taken out of the package without breaking. Since the peripheral portions 22, 22 of the inner films 20, 20 and the peripheral portion 12 of the outer film 10 are sealed and the two films 20, 20, 10 are integrated, when the rice balls 2 are taken out of the package, 1, 1 can be pulled out from between the two films 20, 20, 10. Further, since the intermediate film 30 is attached to the bent portion 11 of the outer film 10, the intermediate film 30 is separated from the other outer film 10 integrally with the bent portion 11 of the outer film 10.
[0036]
Since the corners of the quadrangular laver 1, 1 protrude from the triangular rice ball 2, the protruding laver 1, 1 can be eaten so as to wrap the rice ball 2 softly according to preference.
[0037]
The present invention can be variously modified within the scope of the technical matters described in the claims without being limited to the embodiments of the present invention. In the embodiment of the invention described above, the outer film 10, the inner films 20, 20 and the laver 1, 1 are formed in a rectangular shape, and the corners of the rectangular laver 1, 1 are double overlapped with the triangular rice ball 2. Is done. Then, in order to save the usage amount of the laver 1, the laver 1 may be triangular. In this case, the outer film 10 and the inner films 20, 20 may have a shape with corners cut off.
[0038]
【The invention's effect】
According to the present invention, the peripheral portion of the outer film to be folded in half and the three peripheral portions of the two inner films that are superimposed on the inner surface of the outer film except for the bent portion of the outer film are formed of seaweed. By sealing the peripheral part in a state where the outer film is folded in such a way that each inner film is bonded to the processed rice food such as rice ball, the processed rice food is Packaged with margin. Further, since the sheet-like food is sandwiched between the intermediate film and the inner film and the outer film attached to the bent portion of the outer film, the moisture of the cooked rice food prevents the sheet-like food from getting wet. be able to. Therefore, the processed rice cooked food such as the onigiri wrapped in the packaged rice cooked food according to the present invention can be maintained in a soft gripped state and can have a fluffy feeling.
