Description

TECHNICAL FIELD The present invention relates to a packaged rice lump in which a rice lump is packaged with a packaging sheet formed by sandwiching a sheet-shaped food product between an inner film and an outer film, and a method for unpacking the packaged rice lump.

A so-called packed rice lump, which is a lump of rice such as triangular rice ball rice wrapped in a packaging sheet, is sold at convenience stores and the like. As the packaging sheet, a triple-layered packaging sheet formed by sandwiching sheet-like seaweed between an outer film and an inner film is widely known.

For example, in Patent Document 1, an outer film having a dividable portion for dividing the packaging sheet in the longitudinal direction at a central portion in the width direction is provided with an inner film composed of two vertically long film pieces, and the width of the outer film is The inner ends of the film pieces are overlapped on the severable part of the outer film by heat welding to each end in the direction.

To wrap a triangular rice lump with the packaging sheet having the above configuration, put the rice lump on the center in the longitudinal direction of the packaging sheet, cover the rice lump so that one end side of the packaging sheet covers the rice lump, and cover the wrapped packaging sheet. Bend the corners along the triangular surfaces of the triangle rice ball rice, cover the corners on the other end of the packaging sheet so that they intersect on the outer film on one end, and then overlap the ends of the outer film. Are sealed by adhesion or welding.

In order to eat the above-mentioned packaged rice lump, the severable part of the outer film located at the top of the triangular rice slab is pinched to divide the outer film in two in the longitudinal direction, and one of the wrapping sheets divided to the left and right is placed outside. pull. This pulls the outer film half and the inner film piece together.
Next, by pulling the other half of the outer film and the other film piece of the inner film to the outer side on the opposite side, the rice cake remains with the sheet-like seaweed directly covered and can be eaten. ..

Japanese Patent Laid-Open No. 2002-159271

As described above, the packed rice lump of Patent Document 1 has a step of separating the outer film by the separable portion, a step of pulling out one half of the outer film and a film piece of the inner film when unwrapping the other, The three steps of pulling out the half of the outer film and the film piece of the inner film are required.

In particular, for children and elderly people, it is difficult to perform the above three steps smoothly in an orderly manner, and there is a demand for a packed rice cake that can be unpacked more easily.

The present invention clarifies a packaged rice lump that can unpack a rice lump in a simpler method and a method for unpacking the packaged rice lump.

The packaging sheet of the present invention,
A packaging sheet for packaging flat-shaped rice balls,
In a developed state, a rectangular outer film, an inner film provided on the back side of the outer film, and a sheet-shaped food product sandwiched between the outer film and the inner film,
The outer film extends in the width direction at the approximate center in the longitudinal direction, and has a dividing band composed of two rows of dividing portions formed at intervals substantially the same as the thickness of the rice cake to be packaged, Notches are formed on both outer sides of the dividing zone,
The notch has a first side extending along the severable portion with a side edge of the outer film as a base end, and a first edge extending from a tip end of the first side toward the side edge and separated from the severable portion. It is formed in a substantially triangular shape having two sides.

The sheet-shaped food is arranged substantially in the width direction of the outer film,
It is desirable that the first side is formed to have a length that does not reach the sheet-shaped food product.

The inner film is formed of two inner film pieces, and it is preferable that the inner film pieces are arranged with a space therebetween so as not to face the dividing band.

The inner film is formed from two inner film pieces, and it is preferable that the inner film piece has a cutout formed at a position facing the cutout of the outer film.

The packed rice cake of the present invention is formed by packaging the rice cake with the above-mentioned packaging sheet.

According to the packaging sheet of the present invention, the dividing band of the outer film has a width that is substantially the same as the thickness of the rice lump, and forms notches extending outward from the dividing band at both ends of the dividing band. Therefore, it is possible to prevent the dividing band from being bent along the rice cake when the rice cake is wrapped with the packaging sheet. Therefore, the end of the dividing band can be easily grasped, and the packed rice lump can be easily unwrapped.

Then, the packaged rice lump formed by wrapping the rice lump with the packaging sheet of the present invention is divided in the width direction by pulling the dividing band to divide the outer film, and by making the cut face formed in the outer film downward by the division, Due to its own weight, the rice lump falls while pulling out the sheet-shaped food from between the outer film and the inner film, and the rice lump wrapped with the sheet-shaped food can be obtained.

In addition, the inner film is composed of two pieces of inner film, which are arranged at intervals so as to avoid a dividing zone. That is, since the inner film does not face the dividing zone, the inner film does not exist between the bottom surface of the rice cake and the sheet-shaped food, and the bottom surface of the rice cake directly contacts the sheet-shaped food. Therefore, the packaged rice lumps obtained by wrapping the rice lumps with the packaging sheet of the present invention, after dividing the outer film in the width direction by pulling the dividing band, when the cut formed in the outer film by dividing is turned downward. In addition, since the inner film piece is not sandwiched between the bottom surface of the rice cake and the sheet-shaped food, the inner film piece does not hinder the falling of the rice cake. Therefore, the rice lump and the sheet-shaped food can be drawn out smoothly.

Further, the packed rice cake of the present invention does not require complicated steps as in the conventional case, and the packed rice cake can be unpacked extremely easily. Since the method of unwrapping the package is easy to understand, children and the elderly can easily unwrap the packaged lump and eat it.

Hereinafter, the present invention will be described with reference to the drawings.

As shown in FIGS. 1 to 3, the packaging sheet 10 of the present invention has a substantially rectangular sheet shape between a rectangular transparent outer film 20 and an inner film 30 arranged on the back surface side of the outer film 20. It is formed by sandwiching the food 40. In the figure, the thickness of the films 20, 30 and the sheet-shaped food 40 are appropriately omitted. Further, in order to make the drawings easy to understand, films and the like that are not overlapped and are not shown are omitted.

The outer film 20 is a vertically long film in the unfolded state in this embodiment. The outer film 20 has a dividing band 21 that can divide the outer film 20 in the width direction over the entire length at the center in the longitudinal direction.

The illustrated dividing band 21 is formed by adhering the separable portions 22 and 22 such as a cut tape over the entire length in the width direction of the outer film 20, and the separable portions 22 and 22 have the same thickness as the rice cake 60. It is formed in two rows so that the width (W) is substantially matched. In the illustrated embodiment, the separable portions 22 and 22 are adhered to the inner side of the outer film 20 (on the side of the sheet-shaped food 40). Then, when one end of the severable portion 22 is pulled, the outer film 20 can be torn along the severing band 21, and the cut opening 25 (FIGS. 9 to 11) formed by severing the rice can be used when unwrapping the package. Form an opening through which the mass 60 passes.

The outer film 20 has notches 23, 23 formed on both outer sides of the dividing band 21. The notches 23, 23 extend in a direction away from the dividing band 21 from the first side 23a (see FIG. 1) extending along the divisionable portion 22 with the side edge of the outer film 20 as a base end, and the tip of the first side 23a. It is desirable to have a substantially triangular shape including the second side 23b that extends and reaches the side edge. In this case, the first side 23a is formed to have a length that does not reach the sheet-shaped food 40 when the sheet-shaped food 40 is arranged. By forming the notches 23, 23, when the packaging sheet 10 is wrapped around the rice lump 60 and wrapped, the outer film 20 in the vicinity of the dividing band 21 is not rolled in, and the sheet-shaped food 40 is also prevented from being pressed. it can. Of course, the shape and size of the cutouts 23, 23 are not limited to the illustrated embodiment.

The inner film 30 is composed of two inner film pieces 31, 31 of the same shape in this embodiment. The two inner film pieces 31, 31 have the same width as the outer film 20. In addition, as shown in FIGS. 1 to 3, the inner film pieces 31 and 31 have a length such that at least a thickness (W) of the rice cake 60 is formed so as not to face the dividing band 21 of the outer film 20. Are formed on the outer film 20 and are arranged at the center in the longitudinal direction with an interval (W). That is, as shown in FIG. 6, which will be described later, the inner film pieces 31, 31 have a length that does not exist between the bottom surface of the rice lump 60 and the sheet-shaped food 40.

Further, it is preferable that the inner film 30 has notches 32, 32 having the same shape and formed in a position facing the notches 23 of the outer film 20. By forming the notches 32 and 32, when the packaging sheet 10 is wrapped around the rice lump 60 and wrapped, the inner film pieces 31 and 31 in the vicinity of the dividing band 21 are not caught and the sheet-shaped food 40 is pressed. This is because it can be prevented. In the drawing, the notches 32, 32 have the same shape and size as the notches 23, 23 of the outer film 20, but the shape and size of the notches 32, 32 may be different from the notches 23, 23. Absent.

As the inner film 30, it is desirable to use a film made of a material that does not easily adhere to rice grains. For example, the inner film pieces 31 and 31 may be embossed films in which concave portions and convex portions are uniformly distributed. By using the embossed film, it is possible to enhance the dissociation property from the rice lump 60 and prevent the rice grains from adhering to the inner film 30 or the like.

The sheet food 40 is sheet seaweed in the embodiment. Note that the sheet-shaped food 40 is not particularly limited as long as it is a thin food such as a sheet of oboro kelp or a sheet of dried mackerel. The sheet-like food 40 may be a substantially rectangular one, but as shown in the figure, a rectangular corner is chamfered or a longitudinal end is rounded and chamfered. By using it, the rice lump 60 can be easily dropped from the packaging sheet 10 as described later.

As shown in FIG. 1 to FIG. 3, the sheet-shaped food 40 is placed on the outer film 20 substantially at the center in the width direction and the longitudinal direction, and the inner film pieces 31, 31 do not face the dividing band 21 from above. It is placed away from the center. Then, the outer film 20 and the inner film pieces 31, 31 are linearly welded 11 along the vicinity of the peripheral edge of the outer film 20 so as to surround the sheet-shaped food 40, whereby the packaging sheet 10 is created. Note that the sheet-shaped food 40 can be prevented from being displaced by performing one or a plurality of spot weldings 12 and the like in the vicinity of one end or both ends in the longitudinal direction of the sheet-shaped food 40 and in the width direction.

The lump of rice 60 is packaged in the wrapping sheet 10 having the above-described configuration, and the lump of rice 70 is obtained.

The rice lump 60 to be wrapped in the packaging sheet 10 is a flat mass formed by hardening white rice, red rice or the like. Desirably, the both side surfaces are substantially parallel to each other, and the both side surfaces are connected to each other by a flat or curved peripheral surface. Part or all of the rice cake 60 may be sprinkled with sprinkled food such as sesame seeds, placed with ingredients, or sandwiched with ingredients.

The rice lump 60 shown in the drawing is a substantially triangular flat rice ball, but it may be a round or square flat rice ball.

As shown in FIG. 2, the rice cake 60 having the above configuration is placed on the packaging sheet 10 with the inner film 30 side facing upward. In the case of a triangular rice ball, one surface (referred to as a bottom surface) of the rice ball 60 is positioned so as to face the dividing zone 21 and be located between the dividable portions 22 and 22 as shown in FIG. Put. At this time, the inner film pieces 31 and 31 do not contact the bottom surface of the rice lump 60, but the rice lump 60 directly contacts the sheet food 40.

Alternatively, the packaging sheet 10 may be bent in a U shape in advance to sandwich the rice cake 60.

Then, after placing the rice cake 60 on the packaging sheet 10 as shown in FIG. 2, the packaging sheet 10 is covered so as to wrap the rice cake 60 as shown in FIG. 4, and the end of the packaging sheet 10 as shown in FIG. By sealing the portion with the fastening means 50, the packed rice lump 70 can be obtained. Although the fastening means 50 shown in the drawing is a tape, it is also possible to use a label on which the manufacturing date, contents, etc. are described, or to seal by welding.

By providing the cutouts 23 and 32, the packed rice lump 70 described above is provided with the dividing band 21 having the two separable portions 22 and 22 made of the cut tape as shown in FIGS. 5 and 6. It is not caught with the seat 10. Therefore, the dividing band 21 can maintain the shape in which the tips 21a, 21a are projected outward. If the tips 21a, 21a of the dividing band 21 are obstructive when the packed rice cake 70 is conveyed or displayed, it may be attached to the side surface of the packed rice cake 70 with a tape or the like.

FIG. 7 is a sectional view taken along the line BB of FIG. Referring to FIG. 7, the packed rice cake 70 has the dividing band 21 of the outer film 20 and the sheet-like food product 40 located on the bottom surface side, and the inner film pieces 31 and 31 are brought into contact with the bottom surface of the rice cake 60. It can be seen that the bottoms of the rice lumps 60 are placed on the sheet-shaped food 40 without being spaced apart from each other.

In order to unwrap the packed rice cake 70, the body of the packed rice cake 70 is grasped, and one end 21a of the dividing band 21 is grasped as shown in FIG. Since the cutouts 23 and 32 are provided in the outer film 20 and the inner film 30, the dividing band 21 can be in a form protruding from the side surface of the packaged rice lump 70. Since it is not wrapped, it can be easily grasped when opening. Then, by pulling the tip 21a of the grasped dividing band 21 downward, the outer film 20 is divided at a position outside the dividing portions 22 and 22, and the dividing band 21 having a width W corresponding to the thickness of the rice cake 60 is formed. After the removal, the cut 25 shown in FIGS. 9 and 10 appears on the outer film 20.

Then, by turning the cut edge 25 downward, the rice cake 60 is dropped in the direction of the arrow while pulling out the sheet-shaped food 40 by the weight of the rice cake 60, as shown in FIGS. 9 and 10. In the present invention, the inner film pieces 31, 31 are not provided so as to extend to the position facing the bottom surface of the rice lump 60. That is, since the inner film pieces 31 and 31 do not exist on the bottom surface of the falling rice cake 60 and the sheet food 40, they do not interfere with the falling of the rice cake 60 and the extrusion of the sheet food 40, and the rice cake is extremely smooth. The sheet-shaped food 40 can be pulled out by dropping 60.

Further, by dropping the rice lump 60, the rice lump 60 wrapped with the sheet-shaped food 40 can be obtained as shown in FIG. 11.

The above description of the embodiments is for explaining the present invention, and should not be construed as limiting the invention described in the claims or limiting the scope. Further, the configuration of each part of the present invention is not limited to the above embodiment, and it goes without saying that various modifications can be made within the technical scope described in the claims.
