As shown in FIGS. 1 to 4, the packaging material for rice balls of the present invention accommodates a sheet-shaped food product 4 in a housing portion 3 between an outer film 1 and an inner film 2, and a sheet in the housing portion 3. The cover material 5 is arranged between the food product 4 and the outer film 1.

The outer film 1 is a single transparent film made of synthetic resin such as OPP (biaxially oriented polypropylene). The inner film 2 is composed of two films, a transparent left piece film 2A and a right piece film 2B made of synthetic resin such as OPP (biaxially oriented polypropylene), and the inner end portions of the respective films 2A and 2B are It is supposed to be superimposed. The outer film 1 and the inner film 2 are formed in a substantially rectangular shape having the same size, and the left and right end portions 1a and 1b of the outer film 1 and the left and right end portions 2a and 2b of the inner film 2 are heat-sealed to each other. It is supposed to be joined by. Notches 6 are provided at the four corners of the outer film 1 and the inner film 2, respectively. When the triangular shaped rice ball R is covered with the outer film 1 and the inner film 2, the notches 6 make it easy to put together the four corners of the outer film 1 and the inner film 2 located on the top of the rice ball R.

Further, the outer film 1 may have an outer surface on which appropriate characters or patterns are printed, and the inner surface has a center portion in the left-right direction on opposite short sides (upper and lower sides) of the outer film 1. ), two cut tapes 7 are attached, and the cut tapes 7 can be guided and torn. The cut tape 7 can be made of synthetic resin such as PET. The outer film 1 may be formed of a film having a tear direction in the longitudinal direction (longitudinal direction) instead of providing the cut tape 7.

An opening operation piece 9 is formed by providing two cuts 8 on the outside of the cut tape 7 at the central portions of the respective short sides (upper and lower sides) of the outer film 1 which face each other. By pulling the unsealing piece 9, the central portion of the outer film 1 in the left-right direction is torn into strips up to the opposing short sides thereof, so that the outer film 1 can be divided.

The left side film 2A and the right side film 2B of the inner film 2 have the same long sides (left and right sides) as the long sides (left and right sides) of the outer film 1, and short sides (upper and lower sides) of the outer film 1 respectively. Is longer than half of the short sides (upper and lower sides) of the above, and as shown in FIGS. 2 to 4, the respective inner end edges (free ends) overlap each other at the center.

The accommodating portion 3 is an unbonded portion between the outer film 1 and the inner film 2, and accommodates the sheet-shaped food product 4 and the cover material 5.

The sheet-shaped food 4 may be grilled seaweed, but may be any food as long as it is a sheet-shaped food. Examples of the sheet-shaped food product 4 include thinly roasted eggs, tatami sardines and the like, in addition to kelp and bonito flakes formed into a sheet shape with gelatin. The sheet-shaped food 4 has a substantially rectangular shape, and the width in the left-right direction is the same as the length of one side of the bottom surface Ra of the rice ball R, slightly longer, or slightly shorter, and the length in the vertical direction is The length of the rice ball R covers the front surface Rb, the back surface, and the bottom surface Ra. Further, the accommodation of the sheet-shaped food 4 in the accommodation portion 3 may be performed by either a manual method or a machine-automatic insertion method.

The cover material 5 is made of a synthetic resin such as PET, and an upper dividing portion 5b and a lower dividing portion 5c are continuously provided above and below the covering portion 5a of the rice ball R through the upper and lower dividing lines 10 and 11. .. The cover member 5 has a substantially rectangular shape, and the width in the left-right direction is equal to, slightly longer, or slightly shorter than the length of one side of the bottom surface Ra of the rice ball R, and the length in the up-down direction is The lengths of the long sides (left and right sides) of the outer film 1 and the inner film 2 are the same or slightly shorter. In the cover material 5, the upper end 5t, the upper end 1c of the outer film 1 and the upper end 2c of the inner film 2 are joined by heat sealing or the like except for the central portion, and the lower end 5d and the outer It is assumed that the lower end portion 1d of the film 1 and the lower end portion 2d of the inner film 2 are joined together by heat sealing or the like except for the central portion. Therefore, the cover material 5 is joined at the same time as the outer film 1 and the inner film 2, so that the cover material 5 does not require any trouble and can be easily positioned in the housing portion 3 and can be housed at the time of shipping. It will not be biased vertically or horizontally in the part 3.

The cover portion 5a of the cover material 5 covers the entire bottom surface Ra of the rice ball R which has a triangular shape when opened, and the lower sides of the front surface Rb and the back surface, respectively, about 1/3. It is preferable because it is easy to hold and easy to eat. Further, although the upper and lower severable lines 10 and 11 of the cover material 5 are perforated as shown in the figure, they may be half-cuts or the like. Any material can be used as long as it can be easily divided when it is pulled and separated.

The upper separable line 10 of the cover material 5 is composed of a first upper separable line 10a that traverses the cover material 5 and a second upper separable line 10b that longitudinally crosses the cover material 5. Further, the lower severable line 11 of the cover material 5 is composed of a first lower severable line 11a that traverses the cover material 5 and a second lower severable line 11b that vertically extends through the cover material 5.

The first upper severable wire 10a of the upper severable wire 10 is assumed to extend to both left and right edges of the cover material 5, and the second upper severable wire 10b of the upper severable wire 10 is the first upper severable wire. From the center of the movable line 10a toward the upper edge of the cover material 5, it is assumed that the intermediate portion of these is spread. In the illustrated example, the second upper severable line 10b extends to approximately 1/2 of the upper edge of the cover material 5, but the left and right parts of the outer film 1 are respectively exposed when the later-described opening is performed. In order to make it easier to divide when pulling in one direction and separating, the cover material 5 may extend to the upper end edge. Further, the first lower severable wire 11a of the lower severable wire 11 is assumed to extend to both left and right edges of the cover material 5, and the second lower severable wire 11b of the lower severable wire 11 is the first From the center of the lower severable wire 11a to the lower end edge of the cover material 5, it is assumed that the intermediate part between them is spread. In the illustrated example, the second lower severable line 11b extends to about 1/2 of the lower end edge of the cover material 5, but the left and right portions of the outer film 1 are respectively removed at the time of opening described later. In order to make it easier to divide when pulling in one direction and separating, the cover material 5 may extend to the lower end edge.

The first upper severable wire 10a of the upper severable wire 10 is bent or curved toward the upper edge of the cover material 5, and the first lower severable wire 11a of the lower severable wire 11 is The cover member 5 is bent or curved toward the lower edge. In this case, the smaller the bending angle α when bent, the above-mentioned upper severable wire 10 and the lower severable wire when pulling each of the left and right parts of the outer film 1 outwardly at the time of opening to be described later and separating them. 11 is also easy to divide, but since the area where the cover portion 5a of the cover material 5 covers the rice ball R becomes small, it is preferable that the bending angle α be 120 to 170 degrees. Further, the smaller the radius of curvature r when curved is, the upper severable wire 10 and the lower severable wire 11 when the left and right parts of the outer film 1 are pulled outward and separated from each other at the time of opening, which will be described later. The radius of curvature r is preferably 70 to 110 mm because the area covered by the cover portion 5a of the cover material 5 is small, although it is also easy to divide.

Next, the case where the triangular rice ball R is packed using the packing material for rice balls of the present invention will be described.

First, the inner surface of the packing material for rice balls, that is, the inner film 2 is placed on the front side, and one of the triangular surfaces (rear surface) of the rice ball R is placed on the upper side of the inner film 2 as shown in FIG.

Then, the lower part of the packing material for rice balls is lifted up, bent near the bottom surface Ra of the rice ball R, and covered on the rice ball R so as to match the front surface Rb.

Next, the upper and lower parts of the packing material for rice balls that overlap on the left and right of the rice ball R are folded back to the back side and overlapped, and a seal or tape (not shown) is attached to the overlapped part. Attach and fix (see Figure 8).

The rice ball R wrapped with the packing material for rice balls in this way is ready to be sold at a store such as a supermarket or a convenience store.

When the packaging material for rice balls of the present invention is opened, as shown in FIG. 9, the opening operation piece 9 is grasped and pulled by a finger so that the outer film 1 is torn in the same width as the opening operation piece 9 in the tearing direction. It is divided into left and right parts with the center as the boundary.

Therefore, the left and right parts of the outer film 1 are pulled outward and separated. Then, the upper dividing portion 5b and the lower dividing portion 5c of the cover material 5 are the intersections of the first upper dividing possible line 10a and the second upper dividing possible line 10b, and the first lower dividing possible line 11a and the second lower dividing possible line. From the intersection of 11b, it is divided along these severable lines and separated from the cover portion 5a of the cover material 5. Then, the inner film 2 is also separated into left and right piece films 2A and 2B, and as shown in FIG. 10, the sheet food 4 is attached to the rice ball R, and the bottom is covered with the cover 5a of the cover material 5. The rice ball R appears.

When the rice ball R is eaten, if the user holds the portion of the cover material 5 covered with the cover 5a, the sheet-shaped food 4 is not directly touched and becomes soiled and unsanitary, and water and seasonings are added. It will not make your hands sticky.

The packaging material for rice balls of the present invention is configured as described above, and positions the cover portion 5a of the cover material 5 at the substantially central portion of the housing portion 3 between the outer film 1 and the inner film 2. It is easy to cover the bottom portion of the rice ball R with the cover portion 5a of the cover material 5 when opening, without the cover material 5 being biased in the vertical direction or the horizontal direction when being transported or packed at the time of shipping. In addition, the work of releasably attaching the cover material 5 by the heat-sealing portion is unnecessary, and the production time and the production cost are not required.
