Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can be enjoyed when eating a rice wrapped in a film package from the opening to the end of eating without directly touching the rice ball with a dirty hand. Before opening the packaging of the triangular rice ball by the rice bag packaging bag sheet having a hand-grip sheet and a wrapping material such as laver, before opening the triangular rice ball in a state where the rice grab sheet and the laver are divided into the onigiri, especially The present invention relates to a triangular rice ball packaging form that is easy to open. 2. Description of the Related Art Onigiri packaging bag sheets in which laver is packaged, and the oldest conventional example is, for example, Japanese Utility Model Laid-Open No. 5-72.
FIGS. 15, 16 and 17 of US Pat. The onigiri wrapping bag sheet in which the laver is packaged is shown in FIGS. 15, 16 and 17, and the laver and the two inner films are sequentially arranged on an outer film having an opening strip adhered to the center of the width. The two inner films are placed, the edges are overlapped at the width center of the outer film, and the remaining edges are heat-sealed to the periphery of the outer film to accommodate the laver. Then, as shown in FIG. 17, the packaging form of the onigiri is such that the upper half avoiding the middle of the onigiri packaging bag sheet is the lower surface of the sheet, and the lower surface of the triangular onigiri is placed on the lower surface of the sheet, And the rice ball packaging bag sheet is folded up along the bottom of the triangle rice ball in the middle of the rice ball packaging bag sheet, and the lower half avoiding the middle of the rice ball packaging bag sheet is set as the sheet upper surface part, and the sheet upper surface part is a triangle rice ball triangle. The upper surface of the sheet is folded down along the left and right inclined sides of the triangular rice ball, and the remainder is aligned with the lower surface of the sheet, and the lower surface of the sheet is aligned with the left and right inclined sides of the triangular rice ball. Bend the left and right corners in order along the upper surface of the triangular rice ball, and place the points on the left and right corners so that the left and right corners do not open. And composed. To open, pull the end of the opening strip located at the top of the triangular rice ball in the folding direction to divide the exterior film left and right, and tear until the tear reaches the other end of the opening strip. Do. The opening strip will divide the label and open the left and right corners overlapping the upper surface of the triangular rice ball and divide the exterior film left and right. By pulling each half of the exterior film divided into right and left, right and left, the left and right interior films can be completely removed. Triangle rice balls are exposed with nori rolls. [0003] The disadvantages of the onigiri packaging bag sheet in which the laver is packaged and the packaging form of the onigiri are as follows:
It is pointed out in Japanese Patent No. 764 that it cannot be opened successfully. That is, the package when in the packaged state has an overlapping portion in which the upper right portion and the upper left portion are deeply overlapped with each other at the corners, and for preventing display of the overlapping portion, the overlapping portion is prevented from opening. The sticker made of paper for the purpose of use is stuck. For this reason, when the opening strip is pulled, the overlapping portion hinders the progress of the opening strip, so that the opening strip is cut off in the middle and the opening strip can be successfully removed. There was a risk of disappearing. Therefore, it has been pointed out that in such a case, the exterior film is not cut into two pieces neatly, and there is a problem that it takes time to open the package. [0004] To solve the above problems, there is disclosed a conventional onigiri package that can be easily and reliably cut by opening means, and can be easily divided into two and opened. There are many patent gazettes and utility model gazettes. JP-B-7-32679, JP-A-5-162768, JP-A-5-162770, JP-A-7-13
No. 5,917, JP-A-8-242789, JP-A-8-242790, JP-A-5-72763, and JP-A-5-72764. It is said that it can be easily, reliably, and easily opened in two parts. [0005] However, there is no problem at all. JP-B-7-32679, JP-A-5-1627
No. 68, Japanese Unexamined Patent Publication No. 5-162770, Japanese Utility Model Laid-Open No. 5
In the packaging for onigiri disclosed in Japanese Unexamined Patent Publication No. 72763/1993 and Japanese Unexamined Utility Model Publication No. 5-72764, there is an overlapping portion in which the upper right portion and the upper left portion are deeply overlapped with each other at the corners. 15 and FIG. 1 of Japanese Utility Model Laid-Open No. 5-72764 described above, in that a paper seal for display or decoration is attached to prevent
6, and the same as the rice ball wrapping bag sheet in which laver is packaged, as shown in FIG. These inventions or inventions, when the notch or notch provided on the side edge of the upper left corner of the rice ball packaging body, and the notch or notch provided on the side edge of the upper right corner, when packaging a triangle rice ball , By matching across the opening strip, the opening strip,
It says that the notch or notch in the upper left and upper right corners along with the label can be torn. However, when the center of the triangular rice ball is shifted from the center of the outer film, the notch or notch provided on the side edge of the upper left corner of the rice ball packaging body,
The notch or notch provided on the side edge of the upper right corner does not match at the intersection of the side edges, and the opening strip has a notch or notch provided on either the upper left corner or the upper right corner. And not the other notch or notch, and the label will be applied. In most packages, notches or cutouts provided in the upper left corner and the upper right corner do not completely coincide with each other in correspondence with the opening strip. This prevents the opening strip from tearing the notches or notches in the upper left corner and the upper right corner. In particular, notches of I cut, notches of V cut or semi-circle cut give out a film strip, so it is difficult to ensure completeness so that the film strip does not adhere at the time of manufacturing a package for onigiri. There is a risk that small pieces will be eaten together with the rice balls, making it impractical. Further, Japanese Patent Application Laid-Open Nos. Hei 7-135917, Hei 8-242789, Hei 8-242790
In the package for onigiri disclosed in Japanese Patent Laid-Open Publication No. H10-115, four corners are largely removed, and an upper left corner and an upper right corner overlapping the upper surface of the triangular onigiri have a small overlapping area. Of these, the onigiri package disclosed in Japanese Patent Application Laid-Open No. 7-135917 is used for opening by separating the label with an opening strip and then turning up the upper left corner and upper right corner that overlap with a small area. It is said that the strip can tear the exterior film to the end. However, Japanese Patent Application Laid-Open No. Hei 8-24 discloses that it may not be possible to turn up the upper left corner and the upper right corner that overlap with a small area with the opening strip.
2789 and JP-A-8-242790. Onigiri rice balls disclosed in JP-A-8-242789 and JP-A-8-242790 are provided with a plurality of notches on a side edge of a square cutout, so that a label can be opened with an opening strip. After splitting the, it is trying to tear it away from the notch, rather than turning up the upper left corner and upper right corner that overlap in a small area. However, JP-A-7-135917, JP-A-8-242789, and JP-A-8-24
The package for rice balls disclosed in Japanese Patent Publication No. 2790 has the following disadvantages. As a result of forming a cutout in the square, a film strip is obtained, so it is necessary to make sure that the film strip does not adhere when manufacturing the onigiri packaging, and check whether the film strip has adhered Is needed. As disclosed in Japanese Patent Application Laid-Open No. Hei 7-135917, the rice ball wrapper can turn up the upper left corner and the upper right corner, which are overlapped with a small area, after separating the label with an opening strip. If you turn it over,
The opening strip is cut, resulting in incomplete opening. The rate of incomplete opening is quite high. JP-A-7-135917, JP-A-8-2427
No. 89, Japanese Patent Application Laid-Open No. 8-242790, for any of the onigiri packages, the outer film is formed such that the upper film edge and the left and right notch side edges form a portion where the outer film looks triangular. Labels need to be attached,
As a result, the lower edge of the label hangs on the bottom of the triangle of the triangular rice ball, making it difficult to attach the label. When I purchased rice balls at a convenience store and examined them, I found that many of them moved the label position upward because the label was difficult to stick. When the center of the triangular rice ball is displaced from the center of the outer film, the notch provided at the upper left corner of the package for onigiri and the notch provided at the upper right corner of the rice ball package have side edges. At the intersection of each other, it will not match, and the opening strip will match only the notch provided at either the upper left corner or the upper right corner, and will not match the other notch or notch, and the label will be attached Will be. In most packages, the notches provided at the upper left corner and the upper right corner do not completely match the opening strip. In this way, if the label is shifted upward and the center of the triangular rice ball is shifted from the center of the exterior film, the notch is torn from the notch at the upper left corner and upper right corner with the opening strip. Disappears. Since the four corners are largely cut off, the upper left corner and the upper right corner overlapping the upper surface of the triangular rice ball have a small overlapping area, so the buyer turns over the upper left corner and the upper right corner for the hand at the store and further It is possible to flip the inner exterior film. In this regard, the onigiri wrapping bag sheet in which laver is packaged as shown in FIGS. 15, 16 and 17 of Japanese Utility Model Laid-Open Publication No. 5-72764 is not square-cut, and has an upper right corner and an upper left corner. Since the corners are deeply overlapped with each other, the overlapping parts are prevented from opening and a paper label for display or decoration is attached,
It is impossible for the purchaser to turn over the upper left corner and the upper right corner at the store, and further turn the exterior film inside. The rice ball package disclosed in Japanese Utility Model Laid-Open No. 3-108389 has four corners not cut off, and the upper left corner and the upper right corner overlapping the upper surface of the triangular rice ball are deeply overlapped with each other, and have an overlapping area. Is large and the packaging is solid, but the label is not affixed, which may give the buyer the impression that the packaging is incomplete. This onigiri package is not cut off at the four corners, so no film strips are produced during the production of the onigiri package, but it is necessary to add a notch at the time of production, and cut off the edge of the film using a cutter. This is a problem in the production of onigiri packaging because it is difficult to provide many notches. The packaging rice balls disclosed in Japanese Utility Model Publication No. 4-48712 and Japanese Utility Model Publication No. 4-48712 have a corner cut, and a film strip is generated when the package for the rice ball is manufactured. Further, since no label is attached, there is a fear that the buyer may feel that the packaging is incomplete. DISCLOSURE OF THE INVENTION The present invention has been made in view of the above-mentioned point, and when eating a rice wrapped in a film package, from the opening of the rice ball to the end of eating, the rice ball is directly polished with dirty hands.

The fourth invention of the present application is the above-mentioned invention, wherein a portion of the left corner that does not exceed the opening strip is fixed to the exterior film, and a portion of the right corner that does not exceed the opening strip is the exterior. An object of the present invention is to provide a packaging form of a triangular rice ball characterized by being fixed to a film. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A packaging form of a triangular rice ball according to the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the packaging form of the triangular rice ball is such that the opening strip 1 is attached to the width center of the exterior film 2 so as to be equal in length, and the packaging film 2 is opened. Notches 1a, 1a, 1b, 1b for tearing at positions sandwiching both ends of the strip 1
Is provided on a hand-gripping sheet 3 having a length that is about half the length of the exterior film 2 and a slightly smaller width in the center of the exterior film 2, and four places 3 a are attached to the exterior film 2 so that the hand-gripping sheet 3 does not shift. And a laver 4 slightly smaller than the length and width of the exterior film 2 is placed thereon, and further thereon, the length is equal to the length of the exterior film 2 and the width is the exterior film. 2 are placed in order, and the two interior films 5 and 6 having an elongated shape slightly larger than 1/2 of the width of
The edges are overlapped at the center of the width of the wrapper, and the remaining edges are heat-sealed around the outer film 2 to form a rice bag wrapping bag sheet S containing the hand-grip sheet 3 and the laver 4. and, as shown in FIG. 3 (a), (b) , the upper half S ₂ avoiding the middle S ₁ of the rice ball packaging bag sheet S as the sheet lower surface portion S _2, to the seat bottom surface portion S ₂ triangular rice ball M triangular rice ball was placed on the lower surface of the triangular M, and middle S ₁ of the rice ball packaging bag sheet

To fold back. Opening ridge body 1, will tear the further label 9 tore outer film 2 and reaches the intersection between the side edge of the side edge and the left-hand corner corners S _2b of the right corner corner S _2a, strip for opening since positions on both sides sandwiching the body 1 has four tear notch 8, by pulling the opening ridge body 1, the outer film 2 and the label while tearing the right corner corner S _2a and the left-hand corner corner S _2b from the notch 8 9 can be torn. It is sufficient that at least two tear notches 8 are provided with the opening strip 1 interposed therebetween. Further, the tearing notch 8 may be provided in a C shape with the opening strip 1 interposed therebetween.
When the tear notch 8 is provided by fusing, the point heat seals c and d need not be provided. The point heat seals c and d are provided before the tear notch 8 is provided. However, if the left and right corners S _2a and S _2b are pressed so as not to be opened and the label 9 is applied, the point heat seals c and d are provided. c and d are unnecessary. That is, in the packaging apparatus, since there is a bending step of aligning the left and right corners S _2a and S _2b with the sheet upper surface S ₃ of the exterior film, if the label 9 is applied in that step, the point heat seals c and d are Not required. According to the present invention, an onigiri packaging bag sheet in which no squares have been cut out and which has been packed with laver and / or a hand-holding sheet is provided on the upper right corner of the packaging bag sheet on the upper surface of the triangular rice ball. The upper left corner overlaps deeply with each other, and a tear notch is provided at both right and left corners of the triangle overlapping the upper surface of the triangular rice ball, on both sides of the opening strip, and a tear notch is provided.
