2. Description of the Related Art Onigiri sold at convenience stores include a drum-shaped straight-on rice ball wrapped in a single film and a triangular onigiri wrapped in a seaweed wrapping sheet.

[0003] A packaging sheet containing laver for packaging a triangle rice ball, and a packaging method and a packaging form of a triangle rice ball for packaging with the packaging sheet containing laver are illustrated in, for example, Japanese Utility Model Laid-Open No. 5-72764. The details will be described below. The seaweed-containing packaging sheet has the seaweed and two inner films placed in order on an outer film having an opening strip welded to the center of the width of the inner surface, and the two inner films are edged at the width center of the outer film. They are overlapped with each other and the remaining edges are welded to the peripheral portion of the exterior film. The packaging is required to wrap the triangles on the both sides and the bottom of the triangle onigiri in a channel shape with film, wrap the slope of the triangle onigiri with the overhang of the film, and not to open the four corners of the film on the triangle surface of the triangle onigiri. A point seal is applied to the point, and a paper label is attached and sealed. The actual packaging method of the packaging machine is as follows. A round disk of a relay disk provided with rice packed in a triangular pit in a circumferential arrangement of a molded disk, and the rice pushed down from the pit at a predetermined position and superimposed on the lower side of the molded disk. While delivering to the one triangular pit of the circumferential arrangement, the packaging sheet with laver is placed near the upper side of the predetermined triangular pit of the relay disk and against the packaging sheet support erected so as not to interfere with the rising of the rice ball. Supply horizontally, then raise the push-up rod when the relay disk stops intermittently and stop and move the triangular rice ball in one pit of the relay disk with the triangular plate provided at the upper end of the push-up rod together with the seaweed-containing packaging sheet. Penetrate into the triangular pit recessed in the slide block and open on the lower side, and cover the upper triangular surface and the bottom surface of the triangular rice ball with a laver wrapping sheet. Then, slide the slide block sideways, cover the lower triangular surface of the triangular rice ball with the half of the wrapping sheet with laver, and then slide the triangular plate for lowering housed in the upper part of the triangular pit of the slide block. The lifting rod that penetrates the block and fixedly supports the center of the upper surface of the lowering triangular plate is pushed down and penetrates into one triangular pit of the packaging disk, and the four corners of the packaging sheet are rotated intermittently by the packaging disk. Is placed on the triangular face of the triangular rice ball, point-sealing the required part so that it does not open, affixing a paper label and sealing.
To open, start tearing the exterior film from the top of the triangle of the triangular rice ball, tear through the center of the width of the exterior film on the side where the paper label is not affixed, and pass through the center of the bottom of the triangle rice ball and the opposite side Then, the paper label and the outer film are torn, and the package divided into two sides is opened and removed from the bottom surface of the triangular rice ball.
Then, the left and right interior films can be completely removed. Triangle rice balls are exposed with nori rolls.

[0004]

As described above, conventionally, there is no triangular rice ball wrapped in a single film. The above-described method of packaging a drum-shaped straight-wrapped rice ball wrapped with a single film cannot be applied to a triangle rice ball.

On the other hand, the method of packaging a triangular onigiri wrapped in a laver wrapping sheet can be applied as it is to a triangular onigiri wrapped in a single film. That is, packaging is performed using a rectangular film having an opening strip welded to the center of the width of the inner surface. However, the disadvantage of the packaging form of the triangular rice ball disclosed in Japanese Utility Model Laid-Open No. 5-72764 will be inherited as it is. Such a defect means that the left and right triangular corners of the film overlapping the triangular surface of the triangular rice ball have an overlapping portion where the corners are deeply overlapped with each other and a paper label is stuck, so that the opening strip When the body is pulled, the overlapping part hinders the progress of the tearing position by the opening strip, and the film cannot be completely wound, and the packaging cannot be completely bisected. is there.

[0006] An invention for solving the above problem is disclosed in Japanese Patent Publication No. 7-32679, for example. To be more specific, the packaging form using the laver-containing packaging sheet has an overlapping portion in which the upper right portion and the upper left portion of the laver-containing packaging sheet are deeply overlapped with each other at the corners, in order to prevent the overlapping portion from opening. When notches or notches provided on the side edges of the left and right corners of the laver packaging sheet are packaged with a triangular rice ball, the paper labels are stuck at the intersection of the side edges. It is described that the opening strip can tear the notch or notch in the upper left corner and the upper right corner together with the label by matching the opening strip. However, when packaging is performed with the center line of the outer film shifted from the center of the triangular rice ball,
Notches or notches provided at the side edges of the left and right corners of the rice ball packaging body do not match at the intersection of the side edges, and in this state a paper label will be attached, and most packaging will be The problem that the tearing of the film by the opening strip cannot be completely performed by one turn and the packaging cannot be completely bisected cannot be solved. In short, the technology for solving the inconvenience is an incomplete invention that has not sufficiently achieved its purpose, and has not been put to practical use.

[0007] An invention which does not cause the above problems is disclosed, for example, in Japanese Patent Application Laid-Open No. Hei 7-135917. The four corners of the packaging sheet with laver are cut off. Therefore, in the packaging form, the upper left corner and the upper right corner of the laver-containing packaging sheet overlap with a small area. In order to tear the packaging sheet containing laver to the end by pulling the opening strip, the label is formed so that the outer film looks triangular at the upper edge of the label and the side edges of the notch on the left and right sides of the packaging sheet. It is necessary to adhere the label and not to press the left and right corners of the packaging sheet with the label. By pulling the opening strip and tearing the packaging sheet with laver, the label can be cut into two pieces after tearing, tearing up, and turning up the left and right corners that overlap in a small area of the packaging sheet to complete the packaging sheet Can be torn. These inventions have been put to practical use. However, since these inventions also have a defect, when trying to package using a rectangular single film having an opening strip welded at the center of the inner surface and having four corners cut off, the defect remains as it is. It will be inherited. The disadvantages of the invention disclosed in JP-A-7-135917 are listed below. (1) As a result of providing cutouts at the four corners, film strips are obtained, so it is necessary to make sure that film strips do not adhere to the packaging sheet, and check whether film strips are attached. Is needed. (2) After the label is cut by the strip for opening, the upper left corner and the upper right corner that overlap with a small area cannot be turned up, resulting in incomplete opening. Even if it is forcibly turned up, the opening strip is often cut, resulting in incomplete opening. (3) Since it is difficult to attach a label, many of them have shifted the labeling position upward, and tearing by an opening strip cannot be torn at an intermediate position of a paper label. (4) The upper left corner and the upper right corner overlapping the upper surface of the triangular rice ball are small, and the overlapping area is small, so the buyer turns over the upper left corner and upper right corner for the hand at the store. Further, it is possible to turn the exterior film inside.

[0008] The packaging form of the triangular rice ball invented in Utility Model Registration No. 3055539 eliminates all of the disadvantages (1) to (4) above. The triangular rice ball packaging form does not require cutting off the four corners when manufacturing the laver-containing packaging sheet, and can be completely opened. However, there are disadvantages. In the packaging form before the paper label is applied, it is necessary to form two to four long notches at the position hidden by the paper label by pressing the knife edge heated to high heat, which considerably increases the cost of remodeling the machine. . In addition, a conventional packaging machine for packaging a triangular rice ball with a laver-containing packaging sheet, when pushing up the laver and the packaging sheet, half of the packaging sheet may hang down and shift to the left and right, so it is not possible to pack accurately, If the opening strip is displaced from the center of the triangular rice ball, there is a possibility that two to four long notches applied by pressing a knife edge heated to a high temperature at a position hidden by the paper label may break the opening strip. .

According to the present invention, a paper is formed by wrapping the triangular onigiri on both sides and the bottom surface in a channel shape with a film, wrapping the inclined surface of the triangular onigiri with an overhang of the film, and further overlapping the four corners of the film on the triangular surface of the triangular onigiri. Before opening, the seaweed and the triangular rice ball do not come into direct contact with each other.The first step is to cut the paper label diagonally, and the second step is to film the triangular rice ball from the top of the triangle. Start the tearing of the film and tear through the center of the width of the film on the side where the paper label is not affixed, and extend the tear through the center of the bottom of the triangular rice ball to the opposite side. It is easy to remove the torn left and right wrappings from the bottom surface of the triangular rice ball and remove it, and wrap the triangular rice ball in nori. It may be, and its object is to provide a package form of the package sheet and the triangular onigiri Erlenmeyer rice balls. In particular, the invention of the present application is to completely tear the film by one turn even in a packaging form in which the four corners of the sheet are greatly overlapped on the triangular surface of a triangular rice ball, and a large paper label is attached and sealed as a packaging sheet that does not cut the four corners. It is an object of the present invention to provide a wrapping sheet for triangular onigiri and a wrapping form for triangular onigiri. According to the present invention, there is no need to apply two to four long notches by pressing a high-heated knife edge at a position hidden by a paper label, and there is no need to modify a conventional triangular rice ball packing machine. It is an object of the present invention to provide an onigiri packaging sheet and a triangular onigiri packaging form.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A packaging sheet for a triangular onigiri and a packaging form for the triangular onigiri of the present invention will be described with reference to the drawings. As shown in FIG. 1, the packaging sheet S for triangular rice balls
Has a rectangular exterior film 1, and has a label oblique tearing strip 2 welded in the vicinity of a lateral edge of the exterior film 1, and further has a longitudinal edge of the exterior film 1. It has a tearing start end 4 that bisects the package by providing notches 3 and 3 at substantially the center, and further has an end at the widthwise center of the exterior film 1 on the welding surface of the label oblique tear strip 2 of the exterior film 1. Two interior films 5 and 5 whose edges are vertically overlapped are overlapped, and laver 6 which is slightly smaller than the exterior film 1 is sandwiched between the exterior film 1 and the two interior films 5 and 5. A heat seal 7 is applied to a peripheral portion where the exterior film 1 and the two interior films 5 and 5 overlap each other, avoiding an overlapping portion between the two interior films 5 and 5 and a tearing start end 4. Exterior fill A notch 8 is provided at a required position where the heat seal 7 is applied to the inner film 1 and the interior films 5 and 5 so that the end of the label diagonal tear strip 2 is a label diagonal tear start end 2a. A perforation 9 having a length of about 30 mm is provided, and a notch 10 for dividing the body is provided at the end of the perforation 9. The packaging sheet S for a triangular rice ball must not be cut off diagonally at the corner where the label diagonal tearing start end 2a is provided. In other words, the shape of the corner where the label oblique tearing start end 2a is not cut off obliquely is a constituent feature of the invention. The reason is that when the corner is cut off, the packaging sheet S is retracted from the longitudinal edge, and the label diagonal tearing start end 2a does not function positionally. The portion other than the corner where the label oblique tearing start end 2a is provided may be cut obliquely. The notches 3, 3 are provided on the exterior film 1 and the interior films 5,
5 is not given. In the packaging sheet S for triangular rice balls, the heat seal 7 is applied to the exterior film 1 and the interior films 5 and 5 around the laver 6. If the notch 8 is provided only on the exterior film 1, the exterior film 1 is peeled off from the interior film 5 by heat sealing, and it is difficult to peel off. Therefore, notch 8
Is applied to the exterior film 1 and the interior films 5 and 5.
The interior film 5 having the above-mentioned sliding property is not a uniaxially stretched film. When the label diagonal tearing start end 2a is pinched and torn, the perforation 9 is made so that the tear line of the interior film 5 coincides with the tear line of the exterior film 1.
It is good to provide.

The exterior film 1 is a uniaxially stretched film which is transparent and can be torn substantially linearly in one direction. The exterior film 1 is used so that it can be torn to the left and right in the width direction (so that the tear is in the longitudinal direction). Therefore, according to the invention of the present application, the notch 3 or 3 is provided at the approximate center of the longitudinal edge of the exterior film 1 so that the exterior film 1 is torn to the left and right in the width direction. There is no need to stick a tear strip on the surface.

As the interior film 5, a film having fine unevenness on the surface and having a slipperiness is used. The label diagonal tear strip 2 has a width of about 3 mm to 5 mm and a red thickness of 3 mm.
A film having a high tensile strength at about 0 μm to 40 μm and a melting point higher than that of the packaging film 1 by, for example, 20 ° C. is used.

Next, referring to FIGS. 3 (a), 3 (b) and 3 (c), a procedure and a packaging form for packaging the triangular onigiri with the above-configured packaging sheet for triangular onigiri (hereinafter simply referred to as a packaging sheet) S will be described. I will explain. The wrapping sheet S is bent in a channel shape with the interior film 5 inside and wrapped around the triangular surface and the bottom surface on both sides of the triangular rice ball M,
Overhangs S3a, S3 on both sides of one side in the longitudinal direction of the packaging sheet S
b is folded down along the left and right inclined side surfaces of the triangular rice ball, and the remainder is overlapped on the overhangs S2a, S2b on the other side in the longitudinal direction of the packaging sheet, and then the four overhangs S3a, S2a, S2
b and S3b are folded along the left and right inclined sides of the triangular rice ball M, and the left and right corners S2a and S2b extending from the inclined sides of the triangular rice ball M are cut at the label diagonal tearing start end 2a.
Are folded in order along the triangular surface of the triangular onigiri so that the outermost portion comes to the outermost side, and a paper label 11 is attached thereon. More specifically, as shown in FIG. 3 (a), a triangular rice ball M is placed on an upper part S2 avoiding the middle S1 in the longitudinal direction of the packaging sheet S. Then, as shown in FIG. 3 (b), The upper part S2 and the middle part S1 are folded up along the bottom surface of the triangular rice ball M from the division line of the middle part S1, and the lower part S3 avoiding the middle part S1 of the packaging sheet S is bent along the upper surface of the triangular rice ball M triangle. The lower portion S3 of the seat is folded down along the left and right inclined sides of the triangular rice ball M, and the remaining portions S3a and S3b are aligned with the left and right corners S2a and S2b of the upper portion S2. The left and right corners S3a, S2a, S2b, and S3b that protrude outward are folded up along the left and right inclined sides of the triangular rice ball M, and the remaining left and right corners S2a, S2 are left.
b is folded in order along the upper surface of the triangular rice ball M and overlapped (in this embodiment, the right corner S2a on which the label diagonal tear strip 2 is provided is overlapped last), and the right corner which is stacked last In order to prevent the portion S2a from opening, an appropriate portion a closer to the side edge than the label diagonal tear strip 2 at the right corner S2a is welded to the left corner S2b by point heat sealing. At the upper edge and the lower edge, small incisions are made at a fine pitch so as to hide the intersection point b between the side edge of the right corner S2a and the side edge of the left corner S2b of the triangle which sequentially overlaps the upper surface of the triangular rice ball M. A large paper label 11 put in the box is adhered, and the ears S4 and S5 at the two corners formed by packaging are point-sealed in the directions opposite to the arrows. Then, the label diagonal tear strip 2
The label diagonal tearing start end 2a at one end is located on the inclined surface on the left side of the triangular surface on which the label in the triangular rice ball packaging form is affixed and is not covered by the paper label 11. Therefore, the label diagonal tearing start end 2a can be picked. The tearing start end 2a at one end of the label oblique tearing strip 2 is positioned so as to slightly protrude from the top of the triangular surface on which no label is stuck in the triangular rice ball packaging form. According to the above configuration, the present invention does not need to cut the four corners of the packaging sheet S.
Is the right corner S2a of the triangle that overlaps the upper surface of the triangle rice ball M
And a large overlapping area of the left corner S2b can be secured, and a large paper label 11 can be adhered thereon, thus enabling complete sealing. The point heat seal a is provided so as not to make a hole in the film. The actual packaging method in the packaging machine can be implemented by making a design change to a packaging machine for packaging a triangular rice ball with the laver-containing packaging sheet described in the section of [Prior Art]. In detail, the packaging sheet feeding device with laver of the conventional packaging machine is removed, and instead, a strip for tearing the printed continuous film is welded to a continuous film, and a notch is applied and wound. When a design change is made to attach a packaging material supply device that unwinds a film from the raw roll and cuts the film to a fixed size to be a packaging sheet of the present invention, a triangular rice ball can be wrapped with the packaging sheet of the present invention.

To open the paper label 11, the paper label 11 is turned obliquely from one end of the label diagonal tear strip 2 by 180 ° from the label diagonal tear start end 2a, and teared from the perforation 9 to the right corner of the triangular rice ball M. Sever. Since the point heat seal a is applied to the edge rather than the label diagonal tear strip 2, when the paper label 11 is cut diagonally, the point heat seal a peels off and the right corner S2a is separated, The pressing of the left corner S2b can also be released. When the paper label 11 is torn beyond the center of the width, the label diagonal tearing strip 2 reaches the cutting position of the strip cutting notch 10 before completely tearing the paper label 11 obliquely (FIG. 4 (a) )). The cutting of the paper label 11 at an angle can be stopped here, and the right corner S2a is not opened to the end. Next, the tearing start end 4 is turned by 180 ° and the exterior film 1 is formed.
To tear the paper label 11 beyond the bottom surface of the triangular rice ball M. Strip for diagonal tearing of label 2
When the tearing position reaches the side edge of the left corner S2b, the paper label 11 is first cut obliquely, so if the label oblique tear strip 2 is further pulled, the triangular right corner S2
2a and the left corner S2b are rolled up by the label diagonal tear strip 2 (FIG. 4 (b)).
, The packaging film 1 can be torn to the end and the package can be bisected, so that the package bisected to the left and right can be easily spread out from the bottom surface of the triangular rice ball and removed.

The present invention includes the following modifications. (1) Two strips 2 for diagonal tearing may be attached. (2) A C-shaped notch may be used instead of the two notches 3 and 3. (3) The interior films 5 and 5 may have folded edges near the width center and may overlap each other. (4) A notch similar to the notch provided on the paper label 11 may be provided on the side edge of the left corner S2b, and may be torn open.

[0017]
