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.

A drum-shaped straight-wrapped rice ball wrapped with a single film is substantially the same as the packaging method of a bun packaging machine. The details will be described below. The rice ball is supplied on a disk provided at the upper end of the rod, and the sheet film formed by extracting the film fed from the raw roll and cutting it with a cutter is near the upper side of the supplied rice ball and the rice ball rises. The upper part of the sheet film is positioned horizontally near the upper part of the rice ball with respect to the film support installed so as not to interfere with the rice ball, and the elevating cylinder rod is lowered through the circular cylinder and the suction pad provided at the lower end of the elevating cylinder rod. Then, the lifting rod and the lifting cylinder are raised at the same speed, and the lifting rod raises the rice ball and the sheet film through the inside of the circular cylinder to raise the rice ball to a height near the upper side of the circular cylinder. At the same time, the suction pad is released and the lifting cylinder is lifted. After stopping, the peripheral portion of the film covering the upper surface and the peripheral surface of the rice ball and hanging in the circular cylinder was bound to the lower surface of the rice ball and laterally fed onto the side table, and attached to the table at the laterally fed position. The film is heat-sealed so as not to open the binding portion of the film by the heater.

[0004] A packaging sheet containing laver for packaging a triangular rice ball, and a packaging method and a packaging form of a triangle rice ball for packaging with the laver-containing packaging sheet 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. Wrap the film on both sides and the bottom surface of the triangle onigiri in a channel shape with film, wrap the slope of the triangle onigiri with the overhang of the film, and do not open the four corners of the packaging sheet on the triangle surface of the triangle onigiri. A required point is point-sealed, and a paper label is attached and sealed. The actual packaging method in the packaging machine is
Fill the rice into one triangular pit of the circumferential array of the molded disk, push the rice down from the pit at a predetermined position, and superimpose it on the lower side of the molded disk. At the same time, the seaweed-containing packaging sheet is fed horizontally to a film support erected near the upper side of a predetermined triangular pit of the relay disk so as not to interfere with the rise of the rice ball. When the intermittent rotation stops, the push-up rod is raised, and the lower side of the triangular rice ball in one pit of the relay disk is recessed in the upper slide block together with the laver packaging sheet with the triangular plate provided at the upper end of the push-up rod. Penetrate into the open triangular pit, cover the upper and lower triangular faces of the triangular rice ball with a laver wrapping sheet, feed the slide block sideways and hang down Cover the lower triangular surface of the triangular rice ball with the laver wrapping sheet, and then penetrate the slide block into the triangular plate for lowering housed in the upper part of the triangular pit of the slide block. Push down the elevating rod that fixedly supports the center of the upper surface and push it down into one triangular pit of the packaging disk, do not open the four corners of the packaging sheet on the triangular surface of the triangular rice ball in the process of intermittent rotation of the packaging disk Points are sealed at required points as described above, and a paper label is attached and sealed.
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.

[0005]

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 rice ball wrapped in a laver wrapping sheet can be applied as it is to a triangle rice ball 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.

[0007] An invention for solving the above disadvantage is disclosed in, for example, Japanese Patent Publication No. 7-32679. 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.

An invention which does not cause the above-mentioned problems is disclosed in, for example, JP-A-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.

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. From the state of packaging in which the label is made and sealed, the paper label can be cut diagonally to expose one inclined surface of the triangular rice ball to the end and to maintain the triangular bag shape, and to make the triangular rice ball a film Can be eaten by turning over the film overhangs opened on both sides to expose the triangle rice ball by grasping it from above, or can take out the triangle rice ball from the triangle bag and eat it. The purpose is to provide a packaging form. In particular, the present invention uses a film in which the four corners are not cut, and the four corners of the film are greatly overlapped on the triangular surface of a triangular rice ball, and a large paper label is stuck on the triangular surface to seal the paper label. Can be exposed to a large extent so that it can be pulled out and a triangle rice ball taken out.
It is an object of the present invention to provide a packaging form of a triangular rice ball which can be eaten by largely exposing the triangular rice ball which is rolled up on a film or can be taken out of a package and eaten.

And fold the rest over the overhangs on both sides of the other side in the longitudinal direction of the packaging sheet, and then fold the four overhangs along the left and right inclined sides of the triangular onigiri, and further triangular onigiri The left and right corners extending from the inclined side surface are sequentially folded along the triangular surface of the triangular rice ball so that the tearing start end is on the outermost side, and a paper label is affixed thereon. It is another object of the present invention to provide a packaging form of a triangular rice ball. The second invention of the present application is a substantially rectangular packaging film that is made of a uniaxially stretched film that can be torn substantially linearly in one direction, and has a rectangular shape whose longitudinal direction matches the film tearing direction or at least one corner portion that is not cut off, A packaging form for packaging a triangular onigiri by a packaging sheet for a triangular onigiri, which is provided with a short notch in the packaging film corresponding to one corner of the packaging film and serves as a label diagonal tearing start end, Bend the longitudinal direction of the wrapping sheet for triangular onigiri into a channel shape to wrap the triangular face and the bottom side on both sides of the triangular onigiri. Fold it down along the side surface and put the rest on the overhangs on both sides of the other side in the longitudinal direction of the wrapping sheet, and then attach the four overhangs to the left of the triangular rice ball. The left and right corners extending from the inclined side surface of the triangular rice ball are sequentially folded along the triangular surface of the triangular onigiri so that the tearing start end is on the outermost side. It is another object of the present invention to provide a packaging form of a triangular rice ball, wherein a paper label is stuck thereon.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment 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 width of 2 mm to 5 m.
It has a high tensile strength of about 30 μm to about 40 μmm in red at about m and a melting point of, for example, 20
The diagonally tearable opening strip 2 having a high temperature is provided near the one end in the width direction of the slippery onigiri-adhesive surface of the rectangular packaging film 1 having microscopic unevenness on its surface and having slipperiness (near the right end in this embodiment). ) And both ends of the packaging film 1
Are welded in accordance with the longitudinal edges of the packaging film 1 and positioned inside the width direction of the packaging film 1 with respect to the end of the obliquely tear-opening strip 2 and in the vicinity of the obliquely tear-opening strip 2. 5 mm to 1 mm cut and opened in the packaging film 1 so that one end of the oblique tearing strip 2 is used as a label tearing start end.
It is made up of one short notch 3 of about 0 mm.

Next, FIGS. 2 (a), 2 (b) and 2 (c) show a packaging procedure and a packaging form for packaging a triangular rice ball with the above-configured triangular rice ball packaging sheet (hereinafter simply referred to as a packaging sheet) S.
This will be described with reference to FIG. Middle S in the longitudinal direction of the packaging sheet S
In FIG. 2 (a) on the side provided with the notch 3 avoiding 1, a triangular rice ball M is placed on the upper part S2, and then the bottom of the triangular rice ball M from the division line of the upper part S2 and the middle S1 of the packaging sheet S. In FIG. 2 (a), which is folded up along the surface and further avoiding the middle S1 of the packaging sheet S, the lower part S3 is a triangular rice ball M
Bend along the triangular plane of the triangle of
3 is folded down along the left and right inclined sides of the triangular rice ball M, and the remaining portions S3a and S3b are replaced with the left and right corners S2a and S2 of the upper part S2.
b, and left and right corners S3a, S2a, S2
b and S3b are folded up along the left and right inclined side surfaces of the triangular rice ball M, and the remaining left and right corners S2a and S2b are sequentially folded and overlapped along the triangular surface of the triangular rice ball M (in this embodiment, The right corner S2a on which the diagonal tearing strip 2 is provided is overlapped last), and the right corner S2a is opened obliquely so that the right corner S2a that is finally stacked does not open. 2
A suitable point a closer to the side edge is welded to the left corner S2b by point heat sealing, and in this form, the side edge of the right corner S2a of the triangle that sequentially overlaps the triangular surface of the triangular rice ball M And the intersection point b of the side edge of the left corner S2b
Is covered with a large paper label 4 in which small cuts are made at a fine pitch on the upper edge and the lower edge. Then, the label tearing start end 2a at one end of the oblique tearing strip 2 is located on the inclined surface on the left side of the triangular surface to which the label in the triangular rice ball packaging form is attached, and is not covered by the paper label 4. So located. According to the above configuration, the present invention does not need to cut the four corners of the packaging sheet S, and thus the area where the right corner S2a and the left corner S2b of the triangle where the paper label 4 overlaps the upper surface of the triangular rice ball M overlaps. And a large paper label 4
Can be stuck to complete sealing. It should be noted that the point heat seal a does not 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 label, as shown in FIG. 3, one end of the oblique tearing strip 2 is moved 180 degrees from the label tearing start end 2a.
° Turn and diagonally cut the paper label 4. Since the point heat seal a is applied to the edge rather than the obliquely tearing strip 2, if the paper label 4 is cut obliquely, the pressing of the right corner S2a can be released. Therefore, by opening the lower right corner S3b, which is folded inward, upward and opening the upper right corner S2b, which is folded outward, the right inclined surface of the triangular rice ball M can be exposed, and the wrapping is expanded. Because it is open, it is easy to take out the triangular rice ball M, and it is possible to grab the triangular rice ball M from the top of the package and turn over the film overhangs that are open on both sides to expose the triangular rice ball M. Alternatively, a triangular rice ball can be taken out of a triangular bag and eaten.

The embodiment of the packaging form of the triangular rice ball of the second invention is not shown. The packaging sheet for triangular onigiri used in the packaging form of the triangular onigiri of the second invention of the present application About the packaging sheet S for triangular onigiri shown in FIG.
The packaging film 1 uses a uniaxially stretched film instead of a biaxially stretched film. Since the uniaxially stretched film is used, it is not necessary to provide the obliquely tear-open strip 2. The form of packaging using a packaging film 1 provided with a notch 3 using a uniaxially stretched film is the packaging form of the triangular rice ball of the second invention of the present application.

The present invention includes the following modifications. (1) Two oblique tearing strips 2 may be stuck. (2) The film corner where the notch 3 is not provided may be cut off. (3) The first invention of the present application includes a case where the packaging film 1 is configured using a uniaxially stretched film instead of a biaxially stretched film.

[0016]

As described above, the packaging form of the triangular onigiri of the present invention is as follows: (1) Since a film which does not cut the four corners is used, the four corners of the film are greatly overlapped on the triangular surface of the triangular onigiri, and a large paper label is attached and sealed. A reliable and reliable packaging form can be provided. (2) While using a film that does not cut the four corners, there is no trouble that tearing of the film stops halfway when tearing the film and unpacking it, and it is possible to completely tear the film. , Easy open. In detail, wrap the triangle onigiri on both sides and the bottom surface in a channel shape with film, wrap the slope of the triangular onigiri with the overhang of the film, and overlap the four corners of the film on the triangular surface of the triangular onigiri and label it with a paper label. From the state of pasting and sealing the packaging form, as a first step, diagonally cut the paper label with a label diagonal tear strip, and as a second step, start tearing the film from the top of the triangle of the triangular rice ball. By tearing through the center of the width of the film on the side where the paper label is not attached and extending the tear through the center of the bottom of the triangular rice ball to the opposite side, you can tear the paper label and film without trouble. Then, the package divided into two sides can be easily spread out from the bottom surface of the triangular rice ball and removed. (3) By being able to use a film that does not cut the four corners, for a packaging machine that packages a triangular rice ball with the above-mentioned laver-containing packaging sheet, the packaging material supply device is not a packaging material supply device that supplies the sheet film, but a paper label. A packaging material supply device can be adopted in which a film is unwound from an original roll formed by winding a film on which a strip for tearing obliquely is wound and cut into a fixed size to form a sheet film.
